PROSPECTUS

CyrusOne LP

CyrusOne Finance Corp.

Offer to Exchange
Up to $100,000,000 Principal Amount of
6.375% Senior Notes due 2022
for
a Like Principal Amount of
6.375% Senior Notes due 2022
which have been registered under the Securities Act of 1933



          CyrusOne LP and CyrusOne Finance Corp. (the "issuers") are offering to exchange up to $100,000,000 of their outstanding, unregistered 6.375% Senior Notes due 2022 (the "Initial Notes"), for a like principal amount of registered 6.375% Senior Notes due 2022 (the "Exchange Notes"). The Initial Notes and the Exchange Notes are sometimes referred to in this prospectus together as the "Notes," and the transaction to exchange Initial Notes for Exchange Notes is sometimes referred to in this prospectus as the "Exchange Offer" or "this offer." The terms of the Exchange Notes are identical in all material respects to the terms of the Initial Notes, except that the Exchange Notes are registered under the Securities Act of 1933, as amended (the "Securities Act"), and the transfer restrictions, registration rights and related special interest provisions applicable to the Initial Notes do not apply to the Exchange Notes. The Initial Notes may only be tendered in an amount equal to $2,000 in principal amount or in integral multiples of $1,000 in excess thereof. This offer is subject to certain customary conditions and will expire at 5:00 p.m., New York City time, on,                        2015, unless we extend it. The Exchange Notes will not be listed on any securities exchange or any automated dealer quotation system and there is currently no market for the Exchange Notes.

          The Initial Notes are, and the Exchange Notes will be, guaranteed (the "guarantees") on a senior basis by CyrusOne Inc., the sole beneficial owner and sole trustee of CyrusOne GP, which is the sole general partner of CyrusOne LP, CyrusOne GP and all of CyrusOne LP's existing domestic subsidiaries (other than CyrusOne Finance Corp. and CyrusOne Government Services LLC). In addition, each of CyrusOne LP's domestic restricted subsidiaries that guarantee any of our other indebtedness or other indebtedness of the guarantors will be required to guarantee the Notes in the future (together with CyrusOne Inc. and all of CyrusOne LP's existing domestic subsidiaries (other than the CyrusOne Finance Corp. and CyrusOne Government Services LLC), the "guarantors"). All references to the Notes include references to the related guarantees.

          The Initial Notes are, and the Exchange Notes will be, unsecured senior obligations of the issuers, ranking equal in right of payment with all of the issuers' existing and future unsecured senior debt, including the Existing Notes (as defined below), and senior in right of payment to all of the issuers' future subordinated debt, if any. The Initial Notes are, and the Exchange Notes will be, effectively subordinated to any of the issuers' existing and future secured debt to the extent of the value of the assets securing such debt. The guarantees relating to the Initial Notes are, and the guarantees relating to the Exchange Notes will be, ranked equal in right of payment with all of the guarantors' existing and future unsecured senior debt and senior in right of payment to all of the guarantors' future subordinated debt, if any. The guarantees relating to the Initial Notes are, and the guarantees relating to the Exchange Notes will be, effectively subordinated to any of the guarantors' existing and future secured debt to the extent of the value of the assets securing such debt. In addition, as with the Initial Notes, the Exchange Notes will be structurally subordinated to the liabilities of any non-guarantor subsidiaries.

          Both the Existing Notes and the Exchange Notes will be governed by the same indenture, will constitute the same class of securities for the purposes of the indenture and will vote together on all matters. The Initial Notes were issued under a CUSIP number different from the CUSIP number applicable to the Existing Notes. Holders that exchange Initial Notes in the Exchange Offer will receive Exchange Notes that have the same CUSIP number as the Existing Notes and, as a result, the Exchange Notes will be fungible in the trading market with the Existing Notes.

          For a more detailed description of the Exchange Notes, see "Description of the Notes."

          Each broker-dealer that receives Exchange Notes for its own account pursuant to the Exchange Offer must acknowledge that it will deliver a prospectus meeting the requirements of the Securities Act in connection with any resale of such Exchange Notes. The letter of transmittal states that by so acknowledging and by delivering such a prospectus, a broker-dealer will not be deemed to admit that it is an "underwriter" within the meaning of the Securities Act. This prospectus, as it may be amended or supplemented from time to time, may be used by a broker-dealer in connection with resales of Exchange Notes received in exchange for Initial Notes where such Initial Notes were acquired by such broker-dealer as a result of market-making activities or other trading activities. We have agreed that, during the period described in Section 4(a)(3) of the Securities Act and Rule 174 thereunder that is applicable to transactions by brokers or dealers with respect to Exchange Notes, we will use our commercially reasonable efforts to make this prospectus, as amended and supplemented, available to broker-dealers for use in connection with resales of Exchange Notes.



          Investing in our securities involves a high degree of risk. See "Risk Factors" beginning on page 11 of this prospectus for a discussion of certain factors you should consider in connection with this Exchange Offer.

          We are not asking for a proxy and you are requested not to send us a proxy.



          NEITHER THE SECURITIES AND EXCHANGE COMMISSION (THE "SEC") NOR ANY STATE SECURITIES COMMISSION HAS APPROVED OR DISAPPROVED OF THESE SECURITIES OR PASSED UPON THE ADEQUACY OR ACCURACY OF THIS PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE.

The Cervalis Acquisition

        On July 1, 2015, our operating partnership completed its acquisition of Cervalis Holdings LLC, a Delaware limited liability company ("Cervalis") for approximately $400.0 million, excluding transaction related expenses and subject to customary purchase price adjustments. As a result of the acquisition of Cervalis (the "Cervalis Acquisition"), Cervalis is a wholly owned subsidiary of CyrusOne LP and we acquired four Tier 3+ data center facilities and two work area recovery facilities (the "Cervalis Facilities") serving the New York metropolitan area.

        The Cervalis Facilities currently comprise more than 500,000 gross square feet of space, including more than 120,000 CSF and over 100,000 square feet of work area recovery space. In the year ended December 31, 2014 and in the six months ended June 30, 2015, Cervalis generated revenues of approximately $69.0 million and $39.5 million, respectively, with approximately two-thirds of such revenues being derived from colocation services and the remainder from interconnection, managed services and work area recovery products. As of June 30, 2015, 79% of the CSF within the Cervalis Facilities was utilized. In addition to the currently available raised floor space, it currently has capacity under powered shell to deliver an incremental 50,000 CSF.

        The Cervalis Acquisition is expected to provide additional benefits to us, including the following:

Summary of the Terms of the Exchange Offer

Background

  On July 1, 2015, we completed a private placement of $100,000,000 of our 6.375% Senior Notes due 2022. In connection with this private placement, we entered into a registration rights agreement in which we agreed, among other things, to complete this Exchange Offer.

The Exchange Offer

 

We are offering to exchange the unregistered Initial Notes for a like principal amount of 6.375% Senior Notes due 2022, which have been registered under the Securities Act. The Initial Notes may only be tendered in an amount equal to $2,000 in principal amount or in integral multiples of $1,000 in excess thereof. See "The Exchange Offer—Terms of the Exchange Offer."

 

In order to exchange the Initial Notes, you must follow the required procedures, and we must accept the Initial Notes for exchange. We will exchange all Initial Notes validly tendered and not validly withdrawn prior to the expiration date. See "The Exchange Offer."

Resale of Exchange Notes

 

Based on interpretations of the SEC staff, as described in previous no-action letters, we believe that Exchange Notes issued pursuant to the Exchange Offer in exchange for Initial Notes may be offered for resale, resold and otherwise transferred without compliance with the registration and prospectus delivery provisions of the Securities Act, provided that:

 

you are acquiring the Exchange Notes issued in this offer in the ordinary course of your business;

 

you have not engaged in, do not intend to engage in, and have no arrangement or understanding with any person to participate in a distribution, (within the meaning of the Securities Act) of the Exchange Notes to be issued in the Exchange Offer; and

 

you are not an "affiliate" of ours, as defined in Rule 405 of the Securities Act.

 

By tendering your Initial Notes as described in "The Exchange Offer—Procedures for Tendering," you will be making representations to this effect. If you fail to satisfy any of these conditions, you cannot rely on the position of the SEC set forth in the no-action letters referred to above and you must comply with the registration and prospectus delivery requirements of the Securities Act in connection with a resale of the Exchange Notes.

 

We base our belief on interpretations by the SEC staff in no-action letters issued to other issuers in exchange offers like ours. We cannot guarantee that the SEC would make a similar decision about our Exchange Offer. If our belief is wrong, you could incur liability under the Securities Act. We will not protect you against any loss incurred as a result of this liability under the Securities Act.

Table of Contents

 

Each broker-dealer that receives Exchange Notes for its own account in exchange for Initial Notes, where such Initial Notes were acquired by such broker-dealer as a result of market-making activities or other trading activities, must acknowledge that it will deliver a prospectus meeting the requirements of the Securities Act in connection with any offer to resell, resale or other transfer of Exchange Notes in the Exchange Offer. See "Plan of Distribution."

Consequences If You Do Not Exchange Your Initial Notes

 

Initial Notes that are not tendered in the Exchange Offer or are not accepted for exchange will continue to bear legends restricting their transfer. You will not be able to offer or sell such Initial Notes unless you are able to rely on an exemption from the requirements of the Securities Act or the Initial Notes are registered under the Securities Act.

 

After the Exchange Offer is completed, we will no longer have an obligation to register the Initial Notes, except under limited circumstances. To the extent that Initial Notes are tendered and accepted in the Exchange Offer, the market for any remaining Initial Notes will be adversely affected. See "Risk Factors—Risks Relating to the Notes and the Exchange Offer—Any Initial Notes that are not exchanged will continue to be restricted securities and may become less liquid."

Expiration Date

 

The Exchange Offer expires at 5:00 p.m., New York City time, on            , 2015, unless we extend such Exchange Offer. See "The Exchange Offer—Expiration Date; Extensions; Amendments."

Issuance of Exchange Notes

 

We will issue Exchange Notes in exchange for Initial Notes tendered and accepted in the Exchange Offer promptly following the expiration date (unless amended as described in this prospectus). See "The Exchange Offer—Terms of the Exchange Offer."

Conditions to the Exchange Offer

Summary of the Terms of the Exchange Notes

        Unless specifically indicated, the summary below describes the principal terms of the Notes (including the Exchange Notes). This summary is not intended to be complete. For a more complete understanding of the Notes, please refer to the section entitled "Description of the Notes" in this prospectus. Other than the restrictions on transfer, registration rights and special interest provisions, the Exchange Notes will have the same financial terms and covenants in all material respects as the Initial Notes, which are summarized as follows:

Issuers

  CyrusOne LP and CyrusOne Finance Corp.

Notes offered

 

$100,000,000 in aggregate principal amount of 6.375% Senior Notes due 2022. The Initial Notes constitute an additional issuance of 6.375% Notes due 2022 pursuant to our indenture, dated as of November 20, 2012, as supplemented, under which $525,000,000 of 6.375% Senior Notes due 2022 were issued on November 20, 2012 (the "Existing Notes"). The Exchange Notes are identical in all material respects to the terms of the Initial Notes, except for the original date of issuance, the date from which interest will initially begin to accrue, that the Exchange Notes are registered under the Securities Act and that the transfer restrictions, registration rights and related special interest provisions applicable to the Initial Notes do not apply to the Exchange Notes. The Exchange Notes will evidence the same debt as the Initial Notes, and both the Initial Notes and the Exchange Notes will be governed by the same indenture.

 

The Exchange Notes are identical in all material respects to the terms of the Existing Notes, except for the original date of issuance, issue price and the date from which interest will initially begin to accrue. Both the Existing Notes and the Exchange Notes will be governed by the same indenture, will constitute the same class of securities for the purposes of the indenture and will vote together on all matters. The Initial Notes were issued under a CUSIP number different from the CUSIP number applicable to the Existing Notes. Holders that exchange Initial Notes in the Exchange Offer will receive Exchange Notes that have the same CUSIP number as the Existing Notes and, as a result, the Exchange Notes will be fungible in the trading market with the Existing Notes.

Maturity date

 

November 15, 2022.

Interest

 

The Notes bear interest at a rate of 6.375% per year, payable semi-annually in cash on May 15 and November 15 of each year. Interest on the Exchange Notes will accrue from the most recent date to which interest on the Initial Notes has been paid, or if no interest has been paid on the Initial Notes, from May 15, 2015. The next interest payment date on the Initial Notes is November 15, 2015.

Guarantees

  The Notes are fully, jointly and severally and unconditionally guaranteed on a senior basis by CyrusOne, the sole beneficial owner and sole trustee of CyrusOne GP, which is the sole general partner of our operating partnership and will also be a guarantor of the Exchange Notes, and all of CyrusOne LP's existing domestic subsidiaries (other than CyrusOne Finance Corp. and CyrusOne Government Services LLC). Each of the guarantors under the Notes also guarantees the credit agreement governing our senior unsecured revolving credit facility and senior unsecured term loan facility (the "Credit Agreement"). Each domestic subsidiary that guarantees indebtedness of CyrusOne LP or any guarantor in the future will also guarantee the Notes.

Ranking

 

The Notes are:

 

senior unsecured obligations of the issuers;

 

pari passu in right of payment with any existing and future unsecured senior indebtedness of the issuers (including the Existing Notes);

 

senior in right of payment to any future subordinated indebtedness of the issuers, if any;

 

effectively subordinated in right of payment to all existing and future secured indebtedness of the issuers to the extent of the value of the collateral securing such indebtedness; and

 

structurally subordinated in right of payment to all indebtedness and other liabilities, including trade payables, of our operating partnership's non-guarantor subsidiaries.

 

Each guarantee is:

 

a senior unsecured obligation of such guarantor;

 

pari passu in right of payment with any existing and future senior unsecured indebtedness of such guarantor;

 

senior in right of payment to any future subordinated indebtedness of such guarantor, if any; and

 

effectively subordinated in right of payment to all secured indebtedness of such guarantor, to the extent of the value of the collateral securing such indebtedness.

As of June 30, 2015, after giving effect to the Cervalis Acquisition, the issuance and sale of $100.0 million principal amount of Initial Notes on July 1, 2015 and the borrowing of $150.0 million under our senior unsecured term loan facility on July 1, 2015, we would have had $993.6 million principal amount of debt outstanding, including $474.8 million principal amount of Notes, $205.0 million under our revolving credit facility, $300.0 million under our term loan facility and $13.8 million of capital leases. In addition, we would have had $154.1 million of other financing arrangements. All of our outstanding indebtedness is unsecured other than our capital leases. As of June 30, 2015, after giving effect to the foregoing, we would have had the ability to borrow up to an additional $437.9 million under our revolving credit facility (not giving effect to the unused portion of the accordion feature in the Credit Agreement, for which we do not have commitments), net of outstanding letters of credit of approximately $7.1 million, subject to satisfying certain financial tests.

 

The non-guarantor subsidiaries generated less than 2% of our combined revenues for both the year ended December 31, 2014 and the six months ended June 30, 2015 and held approximately $43.3 million, or 2%, of our combined assets and approximately $40.7 million, or 3%, of our combined liabilities as of June 30, 2015.

Optional redemption

 

Prior to November 15, 2017, the issuers may redeem the Notes, in whole or in part, at any time at a redemption price equal to 100% of the principal amount of the Notes, plus accrued and unpaid interest to the redemption date, plus the applicable "make-whole" premium set forth in this prospectus. The issuers may redeem the Notes, in whole or in part, at any time on or after November 15, 2017, at a redemption price equal to 100% of the principal amount of the Notes, plus accrued and unpaid interest to the redemption date, plus a premium declining over time as set forth in this prospectus. In addition, at any time on or prior to November 15, 2015, the issuers may redeem up to 35% of the aggregate principal amount of the Notes with the proceeds of certain equity offerings, as described in this prospectus. See "Description of the Notes—Optional Redemption."

Change of control

 

If a "Change of Control" occurs, noteholders may require the issuers to repurchase all or part of their Notes at 101% of the principal amount of the Notes, plus accrued and unpaid interest to the repurchase date. The term "Change of Control" is defined under "Description of the Notes—Certain Definitions."

Certain covenants

  The indenture governing the Notes contains covenants that, among other things, limit our operating partnership's ability and the ability of its restricted subsidiaries to:

 

incur secured or unsecured indebtedness;

 

pay dividends or distributions on its equity interests, or redeem or repurchase equity interests of CyrusOne or CyrusOne LP;

 

make certain investments or other restricted payments;

 

enter into transactions with affiliates;

 

enter into agreements limiting the ability of CyrusOne LP's restricted subsidiaries to pay dividends or make certain transfers and other payments to CyrusOne LP or to other restricted subsidiaries;

 

sell assets; and

 

merge, consolidate or transfer all or substantially all of their assets.

 

CyrusOne LP and its restricted subsidiaries are also required to maintain total unencumbered assets of at least 150% of their unsecured debt on a consolidated basis.

 

These covenants contain important exceptions, limitations and qualifications. For so long as the Notes are rated investment grade by each of Moody's Investors Service, Inc. ("Moody's") and Standard & Poor's Ratings Services ("S&P"), certain covenants will be suspended with respect to the Notes and the subsidiary guarantees will be released. For more details, see "Description of the Notes."

Activities of CyrusOne, CyrusOne GP and CyrusOne Finance Corp.

 

The indenture governing the Notes restricts the activities of CyrusOne, CyrusOne GP and CyrusOne Finance Corp. See "Description of the Notes—Covenants—Limitation on Activities of Holdings and CyrusOne GP" and "Description of the Notes—Covenants—Limitation on Activities of Finance Corp."

No public trading market

 

The Exchange Notes will not be listed on any national securities exchange or any automated dealer quotation system. As a result, an active trading market for the Exchange Notes may not develop or be sustained. If an active trading market does not develop, the market price and liquidity of the Exchange Notes may be adversely affected. See "Risk Factors—Risks Related to the Notes and the Exchange Offer."

Governing law

 

The indenture, the Notes and the guarantees are and will be governed by the laws of the state of New York.

Risk factors

 

Investing in the Notes involves a high degree of risk. See "Risk Factors" and all other information included or incorporated by reference into this prospectus (including the "Risk Factors" under Item 1A of our Annual Report on Form 10-K for the fiscal year ended December 31, 2014, incorporated by reference herein) for a discussion of the factors you should carefully consider before deciding to participate in the Exchange Offer or invest in the Notes.

RISK FACTORS

        In considering whether to participate in this Exchange Offer, you should carefully consider all of the information we have included or incorporated by reference in this prospectus. In particular, you should carefully consider the risk factors incorporated by reference from our most recent Annual Report on Form 10-K, the risks discussed below and the other information contained in this prospectus and the documents we incorporate by reference herein before making a decision to participate in this Exchange Offer. Any or all of these risks could have a material adverse effect on our businesses, reputation, financial condition, results of operations and cash flows, the trading price of the Notes and our ability to make payments on the Notes. Some statements in this prospectus, including statements in the following risk factors, constitute forward-looking statements. Please refer to the section entitled "Special Note Regarding Forward-Looking Statements."

Risks Related to the Notes and the Exchange Offer

We have significant outstanding indebtedness that involves significant debt service obligations, limits our operational and financial flexibility, exposes us to interest rate fluctuations and exposes us to the risk of default under our debt obligations.

        As of June 30, 2015, after giving effect to the Cervalis Acquisition, the issuance and sale of $100.0 million principal amount of Initial Notes on July 1, 2015 and the borrowing of $150.0 million under our senior unsecured term loan facility on July 1, 2015, we would have had $993.6 million principal amount of debt outstanding, including $474.8 million principal amount of Notes, $205.0 million under our revolving credit facility, $300.0 million under our term loan facility and $13.8 million of capital leases. In addition, we would have had $154.1 million of other financing arrangements. All of our outstanding indebtedness is unsecured other than our capital leases. As of June 30, 2015, we would have had the ability to borrow up to an additional $437.9 million under our revolving credit facility (not giving effect to the unused portion of the accordion feature in the Credit Agreement, for which we do not have commitments), net of outstanding letters of credit of approximately $7.1 million, subject to satisfying certain financial tests. As of June 30, 2015, the Credit Agreement contained an accordion feature that would have allowed our operating partnership to request an increase in the total commitment by up to $250.0 million. There are no limits on the amount of indebtedness we may incur other than limits contained in the indenture governing the Notes, the Credit Agreement or future agreements that we may enter into or as may be set forth in any policy limiting the amount of indebtedness we may incur adopted by CyrusOne's board of directors. A substantial level of indebtedness could have adverse consequences for our business, financial condition and results of operations because it could, among other things:

11


Table of Contents

Despite our current indebtedness levels, we may still be able to incur substantially more debt, including secured debt. This could exacerbate further the risks associated with our substantial leverage.

        We may be able to incur substantial additional indebtedness in the future, including debt under the Credit Agreement and future credit facilities, some or all of which may be secured and therefore would rank effectively senior to the Notes. As of June 30, 2015, after giving effect to the borrowing of $150.0 million under our senior unsecured term loan facility on July 1, 2015, we would have had $437.9 million of availability under the Credit Agreement, net of outstanding letters of credit of approximately $7.1 million, and the Credit Agreement's accordion feature would have allowed our operating partnership to request an increase in the total commitment by up to an additional $250.0 million. While the indenture governing the Notes has certain restrictions on the incurrence of additional debt by our operating partnership and its restricted subsidiaries, it does not entirely prohibit any additional incurrence and has no restrictions on CyrusOne's ability to incur indebtedness directly. The indenture governing the Notes also allows our operating partnership and its restricted subsidiaries to incur certain secured debt which would be effectively senior to the Notes. In addition, the indenture does not prevent our operating partnership or its restricted subsidiaries from incurring other liabilities that do not constitute indebtedness. See "Description of the Notes." If new debt or other liabilities are added to our current debt levels, the related risks that we now face could intensify.

As with the Existing Notes, the Notes and the related guarantees are unsecured and are and will continue to be effectively junior in right of payment to any secured indebtedness of the issuers or the guarantors.

        As with the Existing Notes, the Notes and the related guarantees are the issuers' and the guarantors' unsecured senior obligations. The Notes and the guarantees are and will continue to be effectively junior in right of payment to all of the issuers' and all of the guarantors' existing and future secured debt, to the extent of the value of the assets securing such obligations. As of June 30, 2015, after giving effect to the Cervalis Acquisition, the issuance and sale of $100.0 million principal amount of Initial Notes on July 1, 2015, and the borrowing of $150.0 million under our senior unsecured term loan facility on July 1, 2015, we would have had $993.6 million principal amount of debt outstanding, including $474.8 million principal amount of Notes, $205.0 million under our revolving credit facility, $300.0 million under our term loan facility and $13.8 million of capital leases. In addition, we would have had $154.1 million of other financing arrangements. All of our outstanding indebtedness is unsecured other than our capital leases. As of June 30, 2015, after giving effect to the borrowing of $150.0 million under our senior unsecured term loan facility on July 1, 2015, we would have had the ability to borrow up to an additional $437.9 million under our revolving credit facility (not giving effect to the unused portion of the accordion feature in the Credit Agreement, for which we do not have commitments), net of outstanding letters of credit of approximately $7.1 million, subject to satisfying certain financial tests. Under the terms of the indenture governing the Notes, subject to satisfaction of

12


Table of Contents

certain other requirements, our operating partnership and its restricted subsidiaries may incur additional debt secured by their respective assets. For a discussion of our operating partnership's ability to incur such secured debt, see "Description of the Notes—Covenants—Limitation on Indebtedness." Because the Notes are unsecured obligations, your right of repayment may be compromised if:

        If any of these events occur, any secured lenders could foreclose on the assets of the issuers or the guarantors in which they have been granted a security interest, in each case to your exclusion, even if an event of default exists under the indenture governing the Notes at such time. As a result, upon the occurrence of any of these events, it is possible that there would be no assets remaining from which your claims could be satisfied or, if any assets remained, they might be insufficient to fully satisfy your claims. You may therefore not be fully repaid if the issuers or the guarantors become insolvent or otherwise fail to make payment on the Notes.

As with the Existing Notes, the Notes are and will continue to be structurally junior in right of payment to the liabilities of any of the issuers' non-guarantor subsidiaries.

        Only CyrusOne, CyrusOne GP and all of our operating partnership's existing domestic subsidiaries (other than CyrusOne Finance Corp. and CyrusOne Government Services LLC) guarantee the Notes. In addition, any new domestic subsidiary of our operating partnership will not be required to guarantee the issuers' obligations under the Notes if it does not guarantee any other debt of CyrusOne, our operating partnership or any other subsidiary guarantor. As with the Existing Notes, the Notes are and will continue to be structurally junior in right of payment to the indebtedness and other liabilities of the issuers' non-guarantor subsidiaries. These non-guarantor subsidiaries are separate and distinct legal entities and have no obligation, contingent or otherwise, to pay any amounts due pursuant to the Notes, or to make any funds available therefor, whether by dividends, loans, distributions or other payments. Any right that the issuers or the subsidiary guarantors have to receive any assets of any of the non-guarantor subsidiaries upon the bankruptcy, liquidation or reorganization of those subsidiaries, and the consequent rights of holders of Notes to realize proceeds from the sale of any of such non-guarantor subsidiaries' assets, will be structurally subordinated to the claims of such non-guarantor subsidiaries' creditors, including trade creditors, mortgage holders and holders of preferred equity interests of those subsidiaries. Accordingly, in the event of a bankruptcy, liquidation or reorganization of any of our non-guarantor subsidiaries, these non-guarantors subsidiaries will pay the holders of their debts, holders of preferred equity interests and their trade creditors before distributing any of their assets to us. The non-guarantor subsidiaries generated less than 2% of our combined revenues for both the year ended December 31, 2014 and the six months ended June 30, 2015 and held approximately $43.3 million, or 2%, of our combined assets and approximately $40.7 million, or 3%, of our combined liabilities as of June 30, 2015, after giving effect to the Cervalis Acquisition.

The agreements governing our indebtedness place restrictions on us, reducing our operational flexibility and creating default risks.

        The agreements governing our indebtedness contain covenants that place restrictions on us and our subsidiaries. These covenants restrict, among other things, our and our subsidiaries' ability to:

13


Table of Contents

        These covenants could impair our ability to grow our business, take advantage of attractive business opportunities or successfully compete. In addition, the Credit Agreement requires us to maintain specified financial metrics and satisfy financial condition tests. The indenture governing the Notes also requires our operating partnership and its subsidiaries to maintain total unencumbered assets of at least 150% of the aggregate principal amount of their outstanding unsecured indebtedness on a consolidated basis. Our ability to comply with these metrics or tests may be affected by events beyond our control, including prevailing economic, financial and industry conditions. A breach of any of these covenants or covenants under any other agreements governing our indebtedness could result in an event of default. Cross-default provisions in our debt agreements could cause an event of default under one debt agreement to trigger an event of default under our other debt agreements. Upon the occurrence of an event of default under any of our debt agreements, the lenders or holders thereof could elect to declare all outstanding debt under such agreements to be immediately due and payable. If we were unable to repay or refinance the accelerated debt, the lenders or holders, as applicable, could proceed against any assets pledged to secure that debt, including foreclosing on or requiring the sale of our data centers, and our assets may not be sufficient to repay such debt in full. For a detailed description of the covenants and restrictions imposed by the indenture governing the Notes, see "Description of the Notes."

The documents that govern our outstanding indebtedness require that we maintain certain financial metrics and, if we fail to do so, we will be in default under the applicable debt instrument, which in turn could trigger defaults under our other debt instruments, which could result in the maturities of all of our debt obligations being accelerated.

        Each of our significant debt instruments requires that we maintain certain financial metrics. The Credit Agreement provides that the total indebtedness of our operating partnership and its subsidiaries shall not exceed 60% of the gross value of the assets of our operating partnership and its subsidiaries, determined based on the capitalized value of the stabilized properties of our operating partnership and its subsidiaries for the preceding fiscal quarter multiplied by four, the book value of the stabilized properties acquired by our operating partnership and its subsidiaries during the four fiscal quarters most recently ended, the book value of development properties owned by our operating partnership and its subsidiaries, unrestricted cash and cash equivalents held by our operating partnership and its subsidiaries, the book value of land assets held by our operating partnership and its subsidiaries and the book value of mortgage notes held by our operating partnership and its subsidiaries. The Credit Agreement also requires that our operating partnership maintain a minimum EBITDA to fixed charges ratio of not less than 1.70 to 1.00 and a minimum consolidated net worth of $1.347 billion, plus 80% of the sum of the net proceeds from any equity offerings by us, our operating partnership and its

14


Table of Contents

subsidiaries and the value of any equity issued upon the contribution of assets to our operating partnership or its subsidiaries after October 9, 2014.

        In addition, the indenture that governs the Notes requires that our operating partnership and its restricted subsidiaries maintain total unencumbered assets of at least 150% of the aggregate principal amount of all of their outstanding unsecured indebtedness on a consolidated basis.

        If we do not continue to satisfy these covenant metrics, we will be in default under the applicable debt instrument, which in turn would trigger defaults under our other debt instruments, which could result in the maturities of all of our debt obligations being accelerated. These events would have a material adverse effect on our liquidity.

Certain exceptions under the indenture permit our operating partnership and its restricted subsidiaries to make distributions to maintain the REIT status of CyrusOne even when they cannot otherwise make restricted payments under the indenture.

        Under the indenture, our operating partnership and its restricted subsidiaries are allowed to make restricted payments only if, at the time they make such a restricted payment, our operating partnership is able to incur at least $1.00 of indebtedness under certain provisions of the "Limitation on Indebtedness" covenant, including that our operating partnership has a consolidated EBITDA to consolidated interest expense coverage ratio of at least 2.0 to 1.0 and its indebtedness is not greater than 60% of adjusted total assets. For a more complete discussion of the restricted payment and debt incurrence covenants of the indenture applicable to the Notes, see "Description of the Notes—Covenants—Limitation on Restricted Payments" and "Description of the Notes—Covenants—Limitation on Indebtedness."

        Even when our operating partnership and its restricted subsidiaries are unable to make restricted payments during a period in which they are unable to incur $1.00 of indebtedness, so long as no default or event of default under the indenture shall have occurred and be continuing, the indenture permits our operating partnership and its restricted subsidiaries to declare or pay any dividend or make any distribution to their equity holders to fund a dividend or distribution by them, so long as CyrusOne believes in good faith that it qualifies as a REIT under the Code, and the declaration or payment of any such dividend or the making of any such distribution is necessary either to maintain CyrusOne's status as a REIT under the Code for any calendar year or to enable CyrusOne to avoid payment of any tax for any calendar year that could be avoided by reason of a distribution by CyrusOne to its shareholders, with such distribution to be made as and when determined by CyrusOne, whether during or after the end of the relevant calendar year.

We may not have the ability to raise the funds necessary to finance the change of control offer required by the indenture.

        Upon the occurrence of certain change of control events, we will be required to offer to repurchase the Notes at 101% of the principal amount thereof, plus accrued and unpaid interest to the date of repurchase. However, it is possible that we will not have sufficient funds at the time of the change of control to make the required repurchase of the Notes, especially if the change of control also constitutes a change of control under the Credit Agreement. Under the Credit Agreement, a change of control constitutes an event of default, which could result in our obligation to repay any outstanding borrowings under the Credit Agreement and repurchase the Notes at the same time. Our failure to repay or repurchase the Notes would constitute an event of default under the indenture.

An active trading market may not develop for the Exchange Notes.

        The failure of a market developing for the Exchange Notes could affect the liquidity and value of the Exchange Notes and you may not be able to sell the Exchange Notes readily, or at all, or at or above the price that you paid.

        As with the Existing Notes and the Initial Notes, we do not intend to apply for the listing of the Exchange Notes on any national securities exchange or any automated dealer quotation system. As a result, an active trading market for the Exchange Notes may not develop or be sustained. The initial purchasers in the offering of the Initial Notes have advised us that, as of the issue date of the Initial Notes, they intended to make a market in the Initial Notes. However, the initial purchasers are not obligated to make a market in the Initial Notes, and one or more initial purchasers may cease any market-making in the Notes at any time. We cannot assure you that any market for the Exchange Notes will develop, or if one does develop, that it will be liquid. If the Exchange Notes are traded, they may trade at a discount from their initial offering price, depending on prevailing interest rates, the market for similar securities, our credit rating, our operating performance and financial condition and other factors. If an active trading market does not develop, the market price and liquidity of the Exchange Notes may be adversely affected. As a result, we cannot assure you that you will be able to sell any of the Exchange Notes at a particular time, at attractive prices, or at all. Thus, you may be required to bear the financial risk of your investment in the Exchange Notes indefinitely.

The trading prices of the Notes will be directly affected by our credit rating.

        The Initial Notes are and the Exchange Notes will be publicly rated by Moody's, S&P and other independent rating agencies. A security rating is not a recommendation to buy, sell or hold securities. These public debt ratings may affect our ability to raise debt. Any future downgrading of the Notes by Moody's and S&P or another rating agency may affect the cost and terms and conditions of our financings and could adversely affect the value and trading price of the Notes.

        Credit rating agencies continually revise their ratings for companies that they follow, including us. Any ratings downgrade could adversely affect the trading price of the Notes or the trading market for the Notes to the extent a trading market for the Notes develops.

Federal and state statutes allow courts, under specific circumstances, to void guarantees and require noteholders to return payments received from guarantors.

        If a bankruptcy case or lawsuit is initiated by unpaid creditors of any guarantor, the debt represented by the guarantees entered into by the guarantor may be reviewed under the federal bankruptcy law and comparable provisions of state fraudulent transfer laws. Under these laws, a guarantee could be voided, or claims in respect of the guarantee could be subordinated to certain obligations of a guarantor if, among other things, the guarantor, at the time it entered into the guarantee, received less than reasonably equivalent value or fair consideration for entering into the guarantee and was one of the following:

        In addition, any payment by a guarantor could be voided and required to be returned to the guarantor or to a fund for the benefit of the guarantor's creditors under those circumstances.

16


Table of Contents

        If a guarantee of a subsidiary were voided as a fraudulent conveyance or held unenforceable for any other reason, holders of the Notes would be solely creditors of CyrusOne, CyrusOne GP, the issuers and creditors of our operating partnership's subsidiaries that have validly guaranteed the Notes. The Notes then would be structurally subordinated to all liabilities of the subsidiary whose guarantee was voided.

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

        The indenture requires that future domestic subsidiaries of our operating partnership guarantee the Notes under certain circumstances. These considerations will also apply to those guarantees.

Any Initial Notes that are not exchanged will continue to be restricted securities and may become less liquid.

        Initial Notes that are not tendered or that we do not accept for exchange will, following this offer, continue to be restricted securities, and the holder may not offer to sell them except pursuant to an exemption from, or in a transaction not subject to, the Securities Act and applicable state securities laws. We will issue Exchange Notes in exchange for the Initial Notes pursuant to this offer only following the satisfaction of the procedures and conditions set forth in "The Exchange Offer—Conditions to the Exchange Offer" and "The Exchange Offer—Procedures for Tendering." Such procedures and conditions include timely receipt by the exchange agent of such Initial Notes (or a confirmation of book entry transfer) and of a properly completed and duly executed letter of transmittal (or an agent's message from DTC). Because we anticipate that most holders of Initial Notes will elect to exchange their Initial Notes for Exchange Notes, we expect that the liquidity of the market for the Initial Notes remaining after the completion of the Exchange Offer will be substantially limited. Any Initial Notes tendered and exchanged in this offer will reduce the aggregate principal amount of Initial Notes outstanding. Following the Exchange Offer, Initial Notes generally will not have any further registration rights, and such Initial Notes will continue to be subject to certain transfer restrictions. Accordingly, the liquidity of the market for the Initial Notes could be adversely affected.

The ability of a broker-dealer to transfer the Exchange Notes may be restricted.

        A broker-dealer that acquired the Initial Notes for its own account as a result of market-making activities or other trading activities must comply with the prospectus delivery requirements of the Securities Act in connection with any resale of the Exchange Notes. Our obligation to make this prospectus available to broker-dealers is limited. Consequently, we cannot guarantee that a proper prospectus will be available to broker-dealers wishing to resell their Exchange Notes.

Risks Related to the Cervalis Acquisition

The Cervalis Acquisition may not achieve its intended benefits or may disrupt our plans and operations.

        There can be no assurance that we will be able to successfully integrate Cervalis with our business or otherwise realize the expected benefits of the Cervalis Acquisition. Our ability to realize the anticipated benefits of the Cervalis Acquisition will depend, to a large extent, on our ability to integrate

Cervalis with our business. The combination of two independent businesses is a complex, costly and time-consuming process. Our business may be negatively impacted by the Cervalis Acquisition if we are unable to effectively manage our expanded operations. The integration process requires significant time and focus from our management team and may divert attention from the day-to-day operations of the combined business. Additionally, the continued integration of Cervalis could disrupt our current plans and operations, which could delay the achievement of our strategic objectives.

        The expected synergies and operating efficiencies of the Cervalis Acquisition may not be fully realized, which could result in increased costs and have a material adverse effect on our business, financial condition, results of operations and/or cash flows. In addition, the overall integration of the businesses may result in material unanticipated problems, expenses, liabilities, competitive responses, loss of customer relationships and diversion of management's attention, among other potential adverse consequences. The risks of combining our operations of the businesses include, among others:

        Many of these risks will be outside of our control and any one of them could result in increased costs, decreases in the amount of expected revenue, and diversion of our management's time and energy, which could have a material adverse effect on our business, financial condition, results of operations and/or cash flows. In addition, even if our operations are integrated successfully with Cervalis', we may not realize the full benefits of the Cervalis Acquisition, including the synergies, operating efficiencies, or sales or growth opportunities that are expected. These benefits may not be achieved within the anticipated time frame or at all.

We may be subject to unknown or contingent liabilities related to Cervalis for which we may have limited recourse against the sellers.

        Cervalis may be subject to unknown or contingent liabilities for which we may have limited recourse against the sellers. Unknown or contingent liabilities might include liabilities for clean-up or remediation of environmental conditions, claims of customers, vendors or other persons dealing with the acquired entities, tax liabilities and other liabilities whether incurred in the ordinary course of business or otherwise. While the sellers are required to indemnify us with respect to breaches of representations and warranties, such indemnification is somewhat limited and subject to various survival periods, materiality thresholds, a deductible of $2.0 million and an aggregate cap on losses, with minimal exceptions, of $4.0 million.

        As a result, there can be no assurance that we will recover all amounts with respect to losses due to breaches of Cervalis' representations and warranties. In addition, the total amount of costs and expenses that we may incur with respect to liabilities associated with Cervalis may exceed our expectations, which may adversely affect our business, financial condition and results of operations.

USE OF PROCEEDS

        This Exchange Offer is intended to satisfy our obligations under the registration rights agreement entered into in connection with the issuance of the Initial Notes. We will not receive any cash proceeds from the issuance of the Exchange Notes in connection with this Exchange Offer.

        In consideration for issuing the Exchange Notes as contemplated by this prospectus, we will receive the Initial Notes in a like principal amount. The Initial Notes surrendered and exchanged for the Exchange Notes will be retired and canceled and cannot be reissued.

DESCRIPTION OF THE NOTES

        You can find the definitions of certain terms used in this description under the subheading "Certain Definitions." In this description, "CyrusOne" refers only to CyrusOne LP, and not to any of its Subsidiaries nor to Holdings or any of its Subsidiaries; the term "Finance Corp." refers to CyrusOne Finance Corp., a wholly-owned Subsidiary of CyrusOne LP with nominal assets which conducts no operations; the term "Issuers" refers to CyrusOne and Finance Corp.; "CyrusOne GP" refers to CyrusOne GP, the general partner of CyrusOne; and "Holdings" refers to CyrusOne, Inc., the 100% owner of CyrusOne GP, and not to any of its Subsidiaries.

        On November 20, 2012, the Issuers issued $525.0 million aggregate principal amount of 6.375% Senior Notes due 2022 (the "Existing Notes") under the indenture (as amended or supplemented, the "indenture") dated as of November 20, 2012, among the Issuers, the Guarantors and Wells Fargo Bank, N.A., as trustee (the "Trustee"). On July 1, 2015, the Issuers issued $100.0 million aggregate principal amount of 6.375% Senior Notes due 2022 (the "Initial Notes") under the indenture in a private transaction that was not subject to the registration requirements of the Securities Act. As of the date of this prospectus, $374.8 million of the Existing Notes and $100.0 million of the Initial Notes are outstanding. Unless otherwise expressly stated or the context otherwise requires, references to the "notes" in this "Description of the Notes" means the Existing Notes, the Initial Notes, the Exchange Notes and any other Additional Notes the Issuers may issue in the future pursuant to the terms of the indenture.

        The Exchange Notes are identical in all material respects to the terms of the Existing Notes, except for the original date of issuance, issue price and the date from which interest will initially begin to accrue. The Exchange Notes are identical in all material respects to the terms of the Initial Notes, except for the original date of issuance, the date from which interest will initially begin to accrue, that the Exchange Notes are registered under the Securities Act, and the transfer restrictions, registration rights and related special interest provisions applicable to the Initial Notes do not apply to the Exchange Notes. The Exchange Notes will evidence the same debt as the Initial Notes, and both the Initial Notes and the Exchange Notes will be governed by the indenture. The Exchange Notes will rank pari passu in right of payment with the Existing Notes and the holders of the Exchange Notes will vote together with the holders of the Existing Notes on any matter submitted to a vote of the holders of the notes under the indenture.

        The Initial Notes were issued under a CUSIP number different from the CUSIP number applicable to the Existing Notes. Holders that exchange Initial Notes in the Exchange Offer will receive Exchange Notes that have the same CUSIP number as the Existing Notes and, as a result, the Exchange Notes will be fungible in the trading market with the Existing Notes.

        As of the date of this prospectus, there is $474.8 million aggregate principal amount of outstanding notes. Accordingly, if all of the Initial Notes are exchanged for Exchange Notes, the Exchange Notes will constitute 21.1% of the total voting power of the notes issued under the indenture that will be outstanding upon completion of this offer.

        The terms of the notes include those stated in the indenture and those made part of the indenture by reference to the Trust Indenture Act of 1939, as amended.

        The following description is a summary of the material provisions of the indenture. It does not restate the indenture in its entirety. We urge you to read the indenture because it, and not this description, defines your rights as holders of the notes. Copies of the indenture are available as set forth below under "—Additional Information." Certain defined terms used in this description but not defined below under "—Certain Definitions" have the meanings assigned to them in the indenture.

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

Brief Description of the Notes and the Note Guarantees

        The Notes.    As with the Existing Notes and the Initial Notes, the Exchange Notes will be:

        Finance Corp. currently has no obligations other than the notes and its Guarantee in respect of CyrusOne's credit agreement.

        The Note Guarantees.    As with the Existing Notes and the Initial Notes, the Exchange Notes will be guaranteed on a joint and several basis by Holdings, CyrusOne GP, all of CyrusOne's existing domestic Restricted Subsidiaries (other than Finance Corp., CyrusOne Government Services LLC and any Receivables Entity) and all of CyrusOne's future Restricted Subsidiaries that are or become required to issue Note Guarantees pursuant to the covenant described below under the caption "—Covenants—Limitation on Issuances of Guarantees by Restricted Subsidiaries."

        The Note Guarantee of each Guarantor is and will be:

        Not all of CyrusOne's Subsidiaries guarantee the notes. In the event of a bankruptcy, liquidation or reorganization of any of these non-guarantor Subsidiaries, the non-guarantor Subsidiaries will pay the holders of their debt and their trade creditors before they will be able to distribute any of their assets to us. The non-guarantor Subsidiaries generated less than 2% of our combined revenues for both the year ended December 31, 2014 and the six months ended June 30, 2015, after giving effect to the Cervalis Acquisition, and held approximately $43.3 million, or 2%, of our combined assets and approximately $40.7 million, or 3%, of our combined liabilities as of June 30, 2015, after giving effect to the Cervalis Acquisition.

        As of the date of this offer, all of our Subsidiaries are "Restricted Subsidiaries." However, under the circumstances described in the definition of "Unrestricted Subsidiaries," we are permitted to designate certain of our Subsidiaries as "Unrestricted Subsidiaries." Our Unrestricted Subsidiaries are not subject to many of the restrictive covenants in the indenture. Our Unrestricted Subsidiaries do not guarantee the notes.

        Each Note Guarantee is limited to the maximum amount that would not render the Guarantor's obligations subject to avoidance under applicable fraudulent conveyance provisions of the United States

23


Table of Contents

Bankruptcy Code or any comparable provision of state law. By virtue of this limitation, a Guarantor's obligation under its Note Guarantee could be significantly less than amounts payable with respect to the notes, or a Guarantor may have effectively no obligation under its Note Guarantee. See "Risk Factors—Risks Related to the Notes and the Exchange Offer—Federal and state statutes allow courts, under specific circumstances, to void guarantees and require noteholders to return payments received from guarantors."

        Each Guarantor that makes a payment under its Note Guarantee is and will be entitled upon payment in full of all guaranteed obligations under the indenture to a contribution from each other Guarantor in an amount equal to such other Guarantor's pro rata portion of such payment based on the respective net assets of all the Guarantors at the time of such payment determined in accordance with GAAP.

        The Note Guarantee of a Subsidiary Guarantor will automatically terminate and be released upon:

        In addition, if on any date following the Original Issue Date the notes are rated Investment Grade by both Rating Agencies and no Default or Event of Default shall have occurred and be continuing under the indenture, then, beginning on that date, the Subsidiary Guarantors will be automatically released from their obligations under the Note Guarantees; provided, however, that following a Reinstatement Date, each of the Restricted Subsidiaries who would have been required to Guarantee the notes but for the foregoing will be required to execute and deliver a supplemental indenture to the indenture providing for a Note Guarantee by such Restricted Subsidiary.

Finance Corp.

        Finance Corp. is a Maryland corporation and a wholly-owned Subsidiary of CyrusOne that was formed for the purpose of facilitating the offering of the Existing Notes by acting as co-issuer. Finance Corp. is nominally capitalized and does not have any operations or revenues. As a result, holders and prospective purchasers of the notes should not expect Finance Corp. to participate in servicing the interest and principal obligations on the notes. See "—Covenants—Limitation on Activities of Finance Corp."

Principal, Maturity and Interest

        The Issuers issued $100.0 million in aggregate principal amount of Initial Notes. The Issuers will exchange up to $100.0 million of Initial Notes for a like principal amount of Exchange Notes in the Exchange Offer. The Issuers may issue Additional Notes under the indenture from time to time after the issuance of the Initial Notes. Any issuance of Additional Notes is subject to all of the covenants in

24


Table of Contents

the indenture, including the covenant described below under the caption "—Covenants—Limitation on Indebtedness." The notes and any Additional Notes subsequently issued under the indenture will be treated as a single class for all purposes under the indenture, including, without limitation, waivers, amendments, redemptions and offers to purchase. The Issuers issued the Initial Notes and will issue the Exchange Notes in minimum denominations of $2,000 and integral multiples of $1,000 in excess of $2,000. The notes will mature on November 15, 2022.

        Interest on the notes accrues at the rate of 6.375% per annum and is payable semi-annually in arrears on May 15 and November 15, commencing on May 15, 2016 in the case of the Exchange Notes. The Issuers will make each interest payment to the holders of record on the immediately preceding May 1 and November 1.

        Interest on the Exchange Notes will accrue from the most recent date to which interest on the Initial Notes has been paid, or if no interest has been paid on the Initial Notes, from May 15, 2015. Interest is computed on the basis of a 360-day year comprised of twelve 30-day months.

Methods of Receiving Payments on the Notes

        The notes are payable as to principal, premium, if any, and interest at the office or agency of the paying agent and registrar within the City and State of New York, or, at the option of the Issuers, payment of interest may be made by check mailed to the holders at their addresses set forth in the register of holders; provided that payment by wire transfer of immediately available funds is required with respect to principal of, premium on, if any, and interest on, all global notes and all other notes the holders who have provided wire transfer instructions to the Issuers or the paying agent to an account in the United States of America.

Paying Agent and Registrar for the Notes

        The Trustee is the current paying agent and registrar. CyrusOne may change the paying agent or registrar without prior notice to the holders of the notes, and CyrusOne or any of its Subsidiaries may act as paying agent or registrar.

Transfer and Exchange

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

Optional Redemption

        At any time prior to November 15, 2015, the Issuers may on any one or more occasions redeem up to 35% of the aggregate principal amount of notes issued under the indenture (including Additional Notes, if any), upon not less than 30 nor more than 60 days' notice to the holders (with a copy to the Trustee), at a redemption price equal to 106.375% of the principal amount of the notes redeemed, plus accrued and unpaid interest, if any, to the date of redemption (subject to the rights of holders of notes on any relevant record date occurring prior to the applicable redemption date to receive interest on the

25


Table of Contents

relevant interest payment date), with an amount of cash equal to the net cash proceeds of an Equity Offering; provided that:

        At any time prior to November 15, 2017, the Issuers may on any one or more occasions redeem all or a part of the notes, upon not less than 30 nor more than 60 days' notice to the holders (with a copy to the Trustee), at a redemption price equal to 100% of the principal amount of the notes redeemed, plus the Applicable Premium as of, and accrued and unpaid interest, if any, to the date of redemption (subject to the rights of holders of notes on any relevant record date occurring prior to the applicable redemption date to receive interest due on the relevant interest payment date).

        Except pursuant to the preceding paragraphs, the notes will not be redeemable at the Issuers' option prior to November 15, 2017.

        On or after November 15, 2017, the Issuers may on any one or more occasions redeem all or a part of the notes, upon not less than 30 nor more than 60 days' notice to the holders (with a copy to the Trustee), at the redemption prices (expressed as percentages of principal amount) set forth below, plus accrued and unpaid interest, if any, on the notes redeemed, to the applicable date of redemption, if redeemed during the twelve-month period beginning on November 15 of the years indicated below (subject to the rights of holders of notes on any relevant record date occurring prior to the applicable redemption date to receive interest on the relevant interest payment date):

Year
  Redemption
Price
 

2017

    103.188 %

2018

    102.125 %

2019

    101.063 %

2020 and thereafter

    100 %

        Unless the Issuers default in the payment of the redemption price, interest will cease to accrue on the notes or portions thereof called for redemption on the applicable redemption date.

Selection and Notice of Redemption

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

        No notes of $2,000 or less can be redeemed in part. Notices of redemption will be mailed by first class mail at least 30 but not more than 60 days before the redemption date to each holder of notes to be redeemed at its registered address, except that redemption notices may be mailed more than 60 days prior to a redemption date if the notice is issued in connection with a defeasance of the notes or a satisfaction and discharge of the indenture. Any redemption may, at CyrusOne's option, be subject to the satisfaction of one or more conditions precedent.

        If any note is to be redeemed in part only, the notice of redemption that relates to that note will state the portion of the principal amount of that note that is to be redeemed. A new note in principal amount equal to the unredeemed portion of the original note will be issued in the name of the holder of notes upon cancellation of the original note. Notes called for redemption become due on the date

26


Table of Contents

fixed for redemption. On and after the redemption date, interest ceases to accrue on notes or portions of notes called for redemption.

Mandatory Redemption; Sinking Fund

        The Issuers are not required to make any mandatory redemption or sinking fund payments for the notes.

Suspension of Covenants

        For so long as (i) the notes are rated Investment Grade by each of S&P and Moody's (or, if either (or both) of S&P and Moody's have been replaced in accordance with the definition of "Rating Agencies," by each of the then applicable Rating Agencies) and (ii) no Default has occurred and is continuing under the indenture, CyrusOne and its Restricted Subsidiaries will not be subject to the covenants in the indenture specifically listed under the following captions in this "Description of the Notes" section of this prospectus (collectively, the "Suspended Covenants"):

        Additionally, during such time as the above referenced covenants are suspended, (i) the Note Guarantees of the Subsidiary Guarantors will also be suspended (the "Suspended Guarantees") and (ii) CyrusOne will not be permitted to designate any Restricted Subsidiary as an Unrestricted Subsidiary unless CyrusOne would have been permitted to designate such Subsidiary as an Unrestricted Subsidiary if the Suspended Covenants had been in effect for such period.

        If at any time the notes' credit rating is downgraded from an Investment Grade rating by either of the Rating Agencies, then the Suspended Covenants and the Suspended Guarantees will thereafter be reinstated as if such covenants and guarantees had never been suspended (the "Reinstatement Date") and will be applicable pursuant to the terms of the indenture (including in connection with performing any calculation or assessment to determine compliance with the terms of the indenture), unless and until the notes subsequently attain an Investment Grade rating from both the Rating Agencies (in which event the Suspended Covenants and the Suspended Guarantees will no longer be in effect for such time that the notes maintain an Investment Grade rating); provided, however, that no Default, Event of Default or breach of any kind will be deemed to exist under the indenture, the notes or the Note Guarantees with respect to the Suspended Covenants or the Suspended Guarantees based on any actions taken or events occurring during the Suspension Period referred to below, or any actions taken at any time pursuant to any contractual obligation arising prior to the Reinstatement Date, regardless of whether such actions or events would have been permitted if the applicable Suspended Covenants or the Suspended Guarantees remained in effect during such period. The period of time between (i) the date of suspension of the Suspended Covenants and the Suspended Guarantees and (ii) the Reinstatement Date, if any, is referred to as the "Suspension Period." On the Reinstatement Date, all

27


Table of Contents

Indebtedness incurred during the Suspension Period will be classified as having been Incurred in compliance with clauses (1), (2) and (3) of the covenant described below under the caption "—Covenants—Limitation on Indebtedness." To the extent such Indebtedness would not be so permitted to be Incurred in compliance with clauses (1), (2) and (3) of the covenant described below under the caption "—Covenants—Limitation on Indebtedness," such Indebtedness will be classified as having been Incurred pursuant to clause (4)(D) of that covenant. Calculations made after the Reinstatement Date of the amount available to be made as Restricted Payments pursuant to the covenant described below under "—Covenants—Limitation on Restricted Payments" will be made as though such covenant had been in effect since the Original Issue Date and throughout the Suspension Period. Accordingly, Restricted Payments made during the Suspension Period will reduce the amount available to be made as Restricted Payments under the first paragraph of the covenant described below under "—Covenants—Limitation on Restricted Payments," to the extent set forth in such covenant. For purposes of determining compliance with the covenant described below under the caption "—Covenants—Limitation on Asset Sales," the amount of Excess Proceeds will be deemed to be zero as of the Reinstatement Date.

        There can be no assurance that the notes will ever achieve or maintain a rating of Investment Grade from any Rating Agency.

Covenants

        The indenture contains, among others, the following covenants.

Limitation on Indebtedness

(3)

Table of Contents

        Notwithstanding the foregoing, CyrusOne and any of its Restricted Subsidiaries may declare or pay any dividend or make any distribution to their equity holders to fund a dividend or distribution by Holdings (and make any corresponding distributions to CyrusOne's partners other than Holdings), so long as (A) Holdings believes in good faith that Holdings qualifies as a real estate investment trust under the Code and the declaration or payment of such dividend, in each case, by Holdings, or the making of such distribution is necessary either to maintain Holdings' status as a real estate investment trust under the Code for any calendar year or to enable Holdings to avoid payment of any tax for any calendar year that could be avoided by reason of a distribution by Holdings to its shareholders, with such distribution by Holdings to be made as and when determined by Holdings, whether during or after the end of the relevant calendar year, and (B) no Default or Event of Default shall have occurred and be continuing.

Limitation on Dividend and Other Payment Restrictions Affecting Restricted Subsidiaries

        CyrusOne will not, and will not permit any of its Restricted Subsidiaries to, create or otherwise cause or suffer to exist or become effective any consensual encumbrance or restriction of any kind on the ability of any Restricted Subsidiary to:

        The foregoing provisions will not restrict any encumbrances or restrictions:

36


Table of Contents

        Nothing contained in this covenant will prevent CyrusOne or any of its Restricted Subsidiaries from restricting the sale or other disposition of property or assets of CyrusOne or its Restricted Subsidiaries that secure Indebtedness of CyrusOne or any of its Restricted Subsidiaries.

Limitation on Issuances of Guarantees by Restricted Subsidiaries

        CyrusOne will not permit any of its Restricted Subsidiaries to Guarantee, directly or indirectly, any Indebtedness of Holdings, CyrusOne or any Subsidiary Guarantor ("Guaranteed Indebtedness"), unless, if such Restricted Subsidiary is not already a Subsidiary Guarantor, such Restricted Subsidiary executes and delivers a supplemental indenture to the indenture providing for a Subsidiary Guarantee by such Restricted Subsidiary within ten business days; provided that this paragraph will not be applicable to any Guarantee of any Restricted Subsidiary that existed at the time such Person became a Restricted Subsidiary and was not Incurred in connection with, or in contemplation of, such Person becoming a Restricted Subsidiary.

        If the Guaranteed Indebtedness:

Limitation on Transactions with Affiliates

        CyrusOne will not, and will not permit any of its Restricted Subsidiaries to enter into, renew or extend any transaction (including, without limitations, the purchase, sale, lease or exchange of property or assets, or the rendering of any service) with any Affiliate of CyrusOne or any of its Restricted

37


Table of Contents

Subsidiaries (each an "Affiliate Transaction"), except upon terms no less favorable to CyrusOne or such Restricted Subsidiary than could be obtained, at the time of such transaction or, if such transaction is pursuant to a written agreement, at the time of the execution of the agreement providing therefor, in a comparable arm's-length transaction with a Person that is not such an Affiliate.

        The foregoing limitation does not limit, and will not apply to:

38


Table of Contents

        Notwithstanding the foregoing, any transaction or series of related transactions covered by the first paragraph of this covenant and not covered by (2) through (13) of the immediately foregoing paragraph (X) the aggregate amount of which exceeds $10.0 million in value must be approved or determined to be fair in the manner provided for in clause (1)(A) or (B) above and (Y) the aggregate amount of which exceeds $35.0 million in value must be determined to be fair in the manner provided for in clause (1)(B) above.

Limitation on Asset Sales

        CyrusOne will not, and will not permit any of its Restricted Subsidiaries to, consummate any Asset Sale, unless:

        Within 365 days after the receipt of any Net Cash Proceeds from an Asset Sale, CyrusOne will or will cause such Net Cash Proceeds (or an amount equal to the amount of such Net Cash Proceeds) to be applied to:

39


Table of Contents

        Pending the application of any such Net Cash Proceeds as described above, CyrusOne may invest such Net Cash Proceeds in any manner that is not prohibited by the indenture.

        The amount of such excess Net Cash Proceeds required to be applied (or to be committed to be applied) during such 365-day period as set forth in the preceding sentence and not applied as so required by the end of such period will constitute "Excess Proceeds." If, as of the first day of any calendar month, the aggregate amount of Excess Proceeds not previously subject to an Offer to Purchase pursuant to this covenant totals more than $25.0 million, CyrusOne must commence, not later than the fifteenth business day of such month, and consummate an Offer to Purchase from the holders of the notes and all holders of other Indebtedness that is pari passu with the notes containing provisions similar to those set forth in the indenture with respect to offers to purchase or redeem with the proceeds of sales of assets, on a pro rata basis, an aggregate principal amount of notes and such other pari passu Indebtedness equal to the Excess Proceeds on such date, at a purchase price equal to 100% of the principal amount of the notes and such other pari passu Indebtedness plus, in each case, accrued interest to the Payment Date.

        If the aggregate principal amount of notes and other pari passu Indebtedness with the notes tendered into such Offer to Purchase exceeds the amount of Excess Proceeds, then the notes and such other pari passu Indebtedness will be purchased on a pro rata basis based on the principal amount of the notes and such other pari passu Indebtedness tendered. Upon completion of each Offer to Purchase, any remaining Excess Proceeds subject to such Offer to Purchase will no longer be deemed to be Excess Proceeds and may be applied to any other purpose not prohibited by the indenture.

Repurchase of Notes upon a Change of Control

        Unless CyrusOne has previously or concurrently mailed a redemption notice with respect to all existing notes as described above under the caption "—Optional Redemption" and all conditions precedent applicable to such redemption notice have been satisfied, CyrusOne must commence, within 30 days of the occurrence of a Change of Control, an Offer to Purchase for all notes then outstanding, at a purchase price equal to 101% of the principal amount of the notes, plus accrued interest to the Payment Date.

        There can be no assurance that CyrusOne will have sufficient funds available at the time of any Change of Control to make any debt payment (including repurchases of notes) required by the foregoing covenant (as well as any covenant that may be contained in other securities of CyrusOne or that might be outstanding at the time).

        Subject to the following paragraph, the provisions described above that require CyrusOne to make an Offer to Purchase following a Change of Control will be applicable regardless of whether any other provisions of the indenture are applicable. Except as described above with respect to a Change of Control, the indenture does not contain provisions that permit the holders of the notes to require that CyrusOne repurchase or redeem the notes in the event of a takeover, recapitalization or similar transaction. In addition, holders of notes may not be entitled to require CyrusOne to purchase their notes in certain circumstances involving a significant change in the composition of CyrusOne's or Holdings' Board of Directors, including in connection with a proxy contest where CyrusOne's or Holdings' Board of Directors does not approve a dissident slate of directors but approves them as Continuing Directors.

        CyrusOne will not be required to make an Offer to Purchase upon a Change of Control if a third party makes the Offer to Purchase in the manner, at the times and otherwise in compliance with the requirements set forth in the indenture applicable to an Offer to Purchase made by CyrusOne and purchases all notes validly tendered and not withdrawn under such Offer to Purchase. Notwithstanding anything to the contrary herein, an Offer to Purchase may be made in advance of a Change of Control,

40


Table of Contents

conditioned upon the consummation of such Change of Control, if a definitive agreement is in place for the Change of Control at the time the Offer to Purchase is made.

        CyrusOne will comply, to the extent applicable, with the requirements of Section 14(e) of the Exchange Act and any other securities laws or regulations in connection with the repurchase of notes as a result of Change of Control. To the extent that the provisions of any securities laws or regulations conflict with the provisions of the covenant described hereunder, we will comply with the applicable securities laws and regulations and will not be deemed to have breached our obligations under the covenant described hereunder by virtue of our compliance with such securities laws or regulations.

        If the terms of any Credit Facilities prohibit CyrusOne from making an Offer to Purchase or from purchasing the notes pursuant thereto, prior to the mailing of the notice to holders, but in any event within 30 days following any Change of Control, CyrusOne covenants to:

        CyrusOne must first comply with the covenant described above before it will be required to purchase notes in the event of a Change of Control; provided, however, that CyrusOne's failure to comply with the covenant described in the preceding sentence or to make an Offer to Purchase because of any such failure shall constitute a default described in clause (4) under "—Events of Default" below (and not under clause (3) thereof).

        The definition of "Change of Control" includes a disposition of all or substantially all of the assets of CyrusOne and its Subsidiaries, taken as a whole, to any Person. Although there is a limited body of case law interpreting the phrase "substantially all," there is no precise established definition of the phrase under applicable law. Accordingly, in certain circumstances there may be a degree of uncertainty as to whether a particular transaction would involve a disposition of "all or substantially all" of the assets of CyrusOne and its Subsidiaries, taken as a whole. As a result, it may be unclear as to whether a Change of Control has occurred and whether a holder of notes may require CyrusOne to make an offer to repurchase the notes as described above.

        The provisions under the indenture governing the notes relative to CyrusOne's obligation to make an offer to repurchase the notes as a result of a Change of Control may be waived or modified with the written consent of the holders of a majority in principal amount of the notes.

SEC Reports and Reports to Holders

        Whether or not Holdings is subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act, Holdings must provide the Trustee and, upon written request, the holders of notes within fifteen (15) business days after filing, or in the event no such filing is required, within fifteen (15) business days after the end of the time periods specified in those sections with:

41


Table of Contents

provided that, the foregoing delivery requirements will be deemed satisfied if the foregoing materials are available on the SEC's EDGAR system or on CyrusOne's or Holdings' website within the applicable time period specified above.

        In addition, following the earlier of (x) the consummation of the initial public offering of Holdings or (y) the consummation of the exchange offer relating to the Existing Notes, whether or not required by the SEC, Holdings will, if the SEC will accept the filing, file a copy of all of the information and reports referred to in clauses (1) and (2) of the preceding paragraph with the SEC for public availability within the time periods specified in the SEC's rules and regulations. If CyrusOne had any Unrestricted Subsidiaries during the relevant period, Holdings will also provide to the trustees and the holders of the notes information sufficient to ascertain the financial condition and results of operations of CyrusOne and its Restricted Subsidiaries, excluding in all respects the Unrestricted Subsidiaries.

        For so long as any of the notes remain outstanding and constitute "restricted securities" under Rule 144, Holdings will furnish to the holders of the notes and prospective investors, upon their request, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act.

        Notwithstanding anything herein to the contrary, Holdings will not be deemed to have failed to comply with any provision of this reporting covenant for purposes of clause (4) set forth below under the caption "—Events of Default" as a result of the late filing or provision of any required information or report until 90 days after the date any such information or report was due.

Limitation on Activities of Finance Corp.

        Finance Corp. will not hold any material assets, become liable for any material obligations or engage in any significant business activities; provided that Finance Corp. may be a co-obligor or guarantor with respect to Indebtedness if CyrusOne is an obligor on such Indebtedness and the net proceeds of such Indebtedness are received by CyrusOne, Finance Corp. or one or more Subsidiary Guarantors. At any time after CyrusOne is a corporation, Finance Corp. may consolidate or merge with or into CyrusOne or any Restricted Subsidiary.

Limitation on Activities of Holdings and CyrusOne GP

        Neither Holdings nor CyrusOne GP will Incur any Indebtedness other than their respective Note Guarantees issued on the Original Issue Date and guarantees of additional Indebtedness (including Additional Notes) or leases of CyrusOne and its Restricted Subsidiaries that is permitted to be Incurred by CyrusOne or such Restricted Subsidiary under the covenant described above under the caption "—Limitation on Indebtedness." In addition:

42


Table of Contents

        Notwithstanding anything to the contrary in this covenant, Holdings and/or CyrusOne GP may consolidate, merge or sell all or substantially all of its assets in accordance with the provisions of the indenture described below under "—Consolidation, Merger and Sale of Assets" and above under "—Repurchase of Notes Upon a Change of Control."

Events of Default

        Events of Default under the indenture are defined as the following:

43


Table of Contents

44


Table of Contents

        If an Event of Default (other than an Event of Default specified in clause (7) or (8) above that occurs with respect to Holdings, CyrusOne GP, an Issuer or any Significant Subsidiary) occurs and is continuing under the indenture, the Trustee or the holders of at least 25% in aggregate principal amount of the notes then outstanding, by written notice to CyrusOne (and to the Trustee if such notice is given by the holders), may, and the Trustee at the request of the holders of at least 25% in aggregate principal amount of the notes then outstanding will, declare the principal of, premium, if any, and accrued interest on the notes to be immediately due and payable. Upon a declaration of acceleration, such principal of, premium, if any, and accrued interest will be immediately due and payable. In the event of a declaration of acceleration because an Event of Default set forth in clause (5) above has occurred and is continuing, such declaration of acceleration will be automatically rescinded and annulled if the event of default triggering such Event of Default pursuant to clause (5) shall be remedied or cured by Holdings, an Issuer or the relevant Significant Subsidiary or waived by the holders of the relevant Indebtedness within 60 days after the declaration of acceleration with respect thereto.

        If an Event or Default specified in clause (7) or (8) above occurs with respect to Holdings, CyrusOne GP, an Issuer or any Significant Subsidiary, the principal of, premium, if any, and accrued interest on the notes then outstanding will automatically become and be immediately due and payable without any declaration or other act on the part of the Trustee or any holder. The holders of at least a majority in principal amount of the outstanding notes by written notice to CyrusOne and to the Trustee, may waive all past defaults and rescind and annul a declaration of acceleration and its consequences if:

        The holders of a majority in aggregate principal amount of the outstanding notes may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on the Trustee. However, the Trustee may refuse to follow any direction that conflicts with law or the indenture, that may involve the Trustee in personal liability, or that the Trustee determines in good faith may be unduly prejudicial to the rights of holders of notes not joining in the giving of such direction and may take any other action it deems proper that is not inconsistent with any such direction received from holders of notes. A holder may not pursue any remedy with respect to the indenture or the notes unless:

45


Table of Contents

        However, such limitations do not apply to the right of any holder of a note to receive payment of the principal of, premium, if any, or interest on, such note or to bring suit for the enforcement of any such payment on or after the due date expressed in the notes, which right shall not be impaired or affected without the consent of the holder.

        The indenture requires certain officers of CyrusOne to certify, on or before a date not more than 120 days after the end of each fiscal year, that a review has been conducted of the activities of CyrusOne and Holdings and the Restricted Subsidiaries and of their performance under the indenture and that CyrusOne, Holdings and the Restricted Subsidiaries have fulfilled all obligations thereunder, or, if there has been a default in fulfillment of any such obligation, specifying each such default and the nature and status thereof. CyrusOne and Holdings will also be obligated to notify the Trustee of any default or defaults in the performance of any covenants or agreements under the indenture.

Consolidation, Merger and Sale of Assets

        The Issuers, Holdings and CyrusOne GP.    None of Holdings, CyrusOne GP nor either of the Issuers will consolidate or merge with or into, or sell, convey, transfer, lease or otherwise dispose (collectively, a "transfer") of all or substantially all of its property and assets (as an entirety or substantially an entirety in one transaction or a series of related transactions) to, any Person or permit any Person to merge with or into Holdings, CyrusOne GP or an Issuer unless:

46


Table of Contents

        Upon any consolidation or merger or any transfer of all or substantially all of Holdings', CyrusOne GP's or such Issuer's assets, in accordance with the foregoing, the successor Person formed by such consolidation or into which Holdings, CyrusOne GP or such Issuer is merged or to which such transfer is made, will succeed to, be substituted for, and may exercise every one of Holdings', CyrusOne GP's or such Issuer's rights and powers under the indenture with the same effect as if such successor Person had been named therein as Holdings, CyrusOne GP or such Issuer and, except in the case of the lease or a sale or other transfer of less than all assets, Holdings, CyrusOne GP or such Issuer will be released from the obligations under the notes and the Note Guarantee, as applicable.

        Subsidiary Guarantors.    No Subsidiary Guarantor will consolidate or merge with or into, or transfer all or substantially all of its property and assets (as an entirety or substantially an entirety in one transaction or a series of related transactions) to, any Person (other than CyrusOne or another Guarantor), unless:

        Notwithstanding the foregoing, the Note Guarantee by a Subsidiary Guarantor that is a Restricted Subsidiary of CyrusOne will be automatically released as set forth under "—The Note Guarantees."

Legal Defeasance and Covenant Defeasance

        CyrusOne may at any time, at the option of its Board of Directors evidenced by a Board Resolution set forth in an officers' certificate, elect to have all of the Issuers' obligations discharged with respect to the outstanding notes and all obligations of the Subsidiary Guarantors discharged with respect to their Note Guarantees ("Legal Defeasance") except for:

        In addition, CyrusOne may, at its option and at any time, elect to have the obligations of the Issuers and the Subsidiary Guarantors released with respect to certain covenants (including their obligation to make an Offer to Purchase upon a Change of Control or Asset Sale, as the case may be) that are described in the indenture ("Covenant Defeasance") and thereafter any omission to comply with those covenants will not constitute a Default or Event of Default with respect to the notes. In the event Covenant Defeasance occurs, all Events of Default described under "—Events of Default" (except those relating to payments on the notes or bankruptcy, receivership, rehabilitation or insolvency

47


Table of Contents

events with respect to Holdings, CyrusOne GP and the Issuers) will no longer constitute an Event of Default with respect to the notes.

        In order to exercise either Legal Defeasance or Covenant Defeasance:

Satisfaction and Discharge

Each holder, by accepting the notes, waives and releases all such liability.

50


Table of Contents

Governing Law

        The indenture provides that it and the notes and the Note Guarantees are governed by, and construed in accordance with, the laws of the State of New York.

Concerning the Trustee

        The indenture provides that, except during the continuance of an Event of Default, the Trustee will not be liable, except for the performance of such duties as are specifically set forth in the indenture. If an Event of Default has occurred and is continuing, the Trustee will use the same degree of care and skill in its exercise of the rights and powers vested in it under the indenture as a prudent person would exercise under the circumstances in the conduct of such person's own affairs.

        The indenture and provisions of the Trust Indenture Act incorporated by reference into the indenture contain limitations on the rights of the Trustee, should it become a creditor of CyrusOne, Holdings or the Subsidiary Guarantors, to obtain payment of claims in certain cases or to realize on certain property received by it in respect of any such claims, as security or otherwise. The Trustee is permitted to engage in other transactions; provided that if it acquires any conflicting interest, it must eliminate such conflict or resign.

THE EXCHANGE OFFER

Purpose of the Exchange Offer

        In connection with the issuance and sale of the Initial Notes on July 1, 2015, we entered into a registration rights agreement with the initial purchasers for the benefit of the holders of the Initial Notes. Under the registration rights agreement, we agreed, among other things, to use our commercially reasonable efforts to file and to have declared effective an exchange offer registration statement under the Securities Act and to consummate an exchange offer. We are conducting this Exchange Offer to satisfy these obligations under the registration rights agreement.

        We are making the Exchange Offer in reliance on the position of the SEC as set forth in certain no-action letters. However, we have not sought our own no-action letter. Based upon these interpretations by the SEC, we believe that a holder of Initial Notes who exchanges such Initial Notes for Exchange Notes in the Exchange Offer, generally may offer the Exchange Notes for resale, sell the Exchange Notes and otherwise transfer the Exchange Notes without further registration under the Securities Act and without delivery of a prospectus that satisfies the requirements of Section 10 of the Securities Act. This does not apply, however, to a holder who is our "affiliate" within the meaning of Rule 405 of the Securities Act. We also believe that a holder may offer, sell or transfer the Exchange Notes only if the holder acknowledges that the holder is acquiring the Exchange Notes in the ordinary course of its business and is not participating, does not intend to participate and has no arrangement or understanding with any person to participate in a distribution of the Exchange Notes.

        Any holder of the Initial Notes using the Exchange Offer to participate in a distribution of Exchange Notes also cannot rely on the no-action letters referred to above. Any broker-dealer who holds Initial Notes acquired for its own account as a result of market- making activities or other trading activities and who receives Exchange Notes in exchange for such Initial Notes pursuant to the Exchange Offer may be a statutory underwriter, must deliver a prospectus meeting the requirements of the Securities Act in connection with any resales of Exchange Notes and must acknowledge such delivery requirement. See "Plan of Distribution."

        Except as described above, this prospectus may not be used for an offer to resell, resale or other transfer of Exchange Notes.

        The Exchange Offer is not being made to, nor will we accept tenders for exchange from, holders of Initial Notes in any jurisdiction in which the Exchange Offer or the acceptance of tenders would not be in compliance with the securities or blue sky laws of such jurisdiction.

Terms of the Exchange Offer

        Upon the terms and subject to the conditions of the Exchange Offer, we will accept any and all Initial Notes validly tendered prior to 5:00 p.m., New York time, on the Expiration Date (as defined below) for the Exchange Offer. Promptly after the Expiration Date (unless extended as described in this prospectus), we will issue an aggregate principal amount of up to $100,000,000 of Exchange Notes and guarantees thereof for a like aggregate principal amount of Initial Notes and guarantees thereof tendered and accepted in connection with the Exchange Offer. The Exchange Notes issued in connection with the Exchange Offer will be delivered promptly after the Expiration Date. Holders may tender some or all of their Initial Notes in connection with the Exchange Offer, but only in an amount equal to $2,000 in principal amount or in integral multiples of $1,000 in excess thereof. The terms of the Exchange Notes will be identical in all material respects to the terms of the Initial Notes except that the Exchange Notes:

74


Table of Contents

        The Exchange Notes will evidence the same debt as the Initial Notes exchanged for the Exchange Notes and will be entitled to the benefits of the same indenture pursuant to which the Initial Notes were issued, which is governed by New York law, including any guarantees thereof. For a complete description of the terms of the Exchange Notes and the guarantees thereof, see "Description of the Notes." We will not receive any cash proceeds from the Exchange Offer.

        As of the date of this prospectus, $100.0 million aggregate principal amount of Initial Notes is outstanding. Only registered holders of the Initial Notes, or their legal representatives and attorneys-in-fact, as reflected in the records of the trustee under the indenture, may participate in this offer. We will not set a fixed record date for determining registered holders of the Initial Notes entitled to participate in this offer. This prospectus, together with the letter of transmittal, is being sent to all registered holders of Initial Notes and to others believed to have beneficial interests in the Initial Notes.

        In connection with the issuance of the Initial Notes, we arranged for the Initial Notes purchased by qualified institutional buyers and those sold in reliance on Regulation S under the Securities Act to be issued and transferable in book-entry form through the facilities of DTC, acting as depositary. Except as described under "Book-Entry, Delivery and Form", Exchange Notes will be issued in the form of a global note registered in the name of DTC or its nominee and each beneficial owner's interest in it will be transferable in book-entry form through DTC. See "Book-Entry, Delivery and Form".

        Holders of Initial Notes do not have any appraisal or dissenters' rights in connection with the Exchange Offer. If you do not tender your Initial Notes or if you tender Initial Notes that are not accepted for exchange, your Initial Notes will remain outstanding and continue to accrue interest but will not retain any rights under the registration rights agreement. Existing transfer restrictions would continue to apply to Initial Notes that remain outstanding. See "—Consequences of Failure to Properly Tender Initial Notes in the Exchange Offer" and "Risk Factors—Risk Factors Relating to the Notes and the Exchange Offer—Any Initial Notes that are not exchanged will continue to be restricted securities and may become less liquid" for more information regarding Initial Notes outstanding after this offer.

        We shall be considered to have accepted validly tendered Initial Notes if and when we have given oral (to be followed by prompt written notice) or written notice to the Exchange Agent (as defined below). The Exchange Agent will act as agent for the tendering holders for the purposes of receiving the Exchange Notes from us.

        If any tendered Initial Notes are not accepted for exchange because of an invalid tender, the occurrence of certain other events described in this prospectus or otherwise, we will return the Initial Notes, without expense, to the tendering holder promptly after the Expiration Date for the Exchange Offer.

        Holders who tender Initial Notes will not be required to pay brokerage commissions or fees or, subject to the instructions in the letter of transmittal, transfer taxes on exchange of Initial Notes in connection with the Exchange Offer. We will pay all charges and expenses, other than certain applicable taxes described below, in connection with the Exchange Offer. See "—Fees and Expenses".

Expiration Date; Extensions; Amendments

        Upon the terms and subject to the conditions described in this prospectus and in the accompanying letter of transmittal, we will accept for exchange any and all Initial Notes validly tendered on or before the Expiration Date and not withdrawn as permitted below. As used in this

75


Table of Contents

section of the prospectus entitled, "The Exchange Offer," the term "Expiration Date" means 5:00 p.m., New York City time, on                        , 2015. If, however, we, in our sole discretion, extend the period of time for which this offer is open, the term "Expiration Date" means the latest time and date to which this offer is so extended. Initial Notes tended in this offer must be in denominations of an amount equal to $2,000 in principal amount or in integral multiples of $1,000 in excess thereof.

        We reserve the right, in our sole discretion:

        If we amend the Exchange Offer in a manner that we consider material, we will disclose such amendment by means of a prospectus supplement, and we will extend the Exchange Offer for a period of five to ten business days.

        If we determine to extend, amend or terminate the Exchange Offer, we will publicly announce this determination by making a timely release through an appropriate news agency.

        If we delay accepting any Initial Notes or terminate the Exchange Offer, we promptly will pay the consideration offered, or return any Initial Notes deposited, pursuant to the Exchange Offer as required by Rule 14e-1(c).

Interest on the Exchange Notes

        Interest on the Exchange Notes will accrue at a rate of 6.375% per year from the most recent date to which interest on the Initial Notes has been paid or, if no interest has been paid on such Initial Notes, from May 15, 2015. Interest on the Notes is payable semiannually in cash in arrears on May 15 and November 15 commencing May 15, 2016.

Conditions to the Exchange Offer

        Notwithstanding any other provision of the Exchange Offer, or any extension of the Exchange Offer, we will not be required to accept for exchange, or to exchange any Exchange Notes for, any Initial Notes and we may terminate the Exchange Offer or, at our option, modify, extend or otherwise amend the Exchange Offer as provided in this prospectus before the acceptance of the Initial Notes, if prior to the Expiration Date:

        The foregoing conditions are for our sole benefit and may be waived by us, in whole or in part, in our absolute discretion. Any determination made by us concerning an event, development or circumstance described or referred to above will be conclusive and binding.

        If any of the foregoing conditions are not satisfied, we may, at any time on or prior to the Expiration Date:

        In addition, subject to applicable law, we may in our absolute discretion terminate the Exchange Offer for any other reason.

Effect of Tender

        Any tender by a holder, and our subsequent acceptance of that tender, of Initial Notes will constitute a binding agreement between that holder and us upon the terms and subject to the conditions of the Exchange Offer described in this prospectus and in the letter of transmittal. The participation in the Exchange Offer by a tendering holder of Initial Notes will constitute the agreement by that holder to deliver good and marketable title to the tendered Initial Notes, free and clear of any and all liens, restrictions, charges, pledges, security interests, encumbrances or rights of any kind of third parties.

Absence of Dissenters' Rights

        Holders of the Initial Notes do not have any appraisal or dissenters' rights in connection with the Exchange Offer.

Procedures For Tendering

        If you wish to participate in the Exchange Offer and your Initial Notes are held by a custodial entity such as a bank, broker, dealer, trust company or other nominee, you must instruct that custodial entity to tender your Initial Notes on your behalf pursuant to the procedures of that custodial entity. Please ensure you contact your custodial entity as soon as possible to give them sufficient time to meet your requested deadline.

        The Exchange Agent and DTC have confirmed that the Exchange Offer is eligible for ATOP with respect to book-entry notes held through DTC. The letter of transmittal, or a facsimile thereof, with any required signature guarantees, or, in the case of book-entry transfer, an agent's message in lieu of the letter of transmittal, and any other required documents, must be transmitted to and received by the Exchange Agent on or prior to the Expiration Date at its address set forth below under the caption "Exchange Agent". Initial Notes will not be deemed to have been tendered until the letter of transmittal and signature guarantees, if any, or agent's message, is received by the Exchange Agent. We have not provided guaranteed delivery procedures in conjunction with the Exchange Offer or under this prospectus.

        The method of delivery of Initial Notes, the letter of transmittal and all other required documents to the Exchange Agent is at the election and risk of the holders. Instead of delivery by mail, we recommend that holders use an overnight or hand delivery service, properly insured. In all cases, sufficient time should be allowed to assure delivery to and receipt by the Exchange Agent on or prior to the Expiration Date. Do not send the letter of transmittal or any Initial Notes to anyone other than the Exchange Agent.

        If you are tendering your Initial Notes in exchange for Exchange Notes and anticipate delivering your letter of transmittal and other documents other than through DTC, we urge you to contact promptly a bank, broker or other intermediary that has the capability to hold notes custodially through

78


Table of Contents

DTC to arrange for receipt of any Initial Notes to be delivered pursuant to the Exchange Offer and to obtain the information necessary to provide the required DTC participant with account information in the letter of transmittal.

        If you are a beneficial owner which holds Initial Notes through Euroclear (as defined below) or Clearstream (as defined below) and wish to tender your Initial Notes, you must instruct Euroclear or Clearstream, as the case may be, to block the account in respect of the tendered Initial Notes in accordance with the procedures established by Euroclear or Clearstream. You are encouraged to contact Euroclear and Clearstream directly to ascertain their procedure for tendering Initial Notes.

Book-Entry Delivery Procedures for Tendering Initial Notes Held with DTC

        If you wish to tender Initial Notes held on your behalf by a nominee with DTC, you must:

        Any financial institution that is a nominee in DTC, including Euroclear and Clearstream, must tender Initial Notes by effecting a book-entry transfer of Initial Notes to be tendered in the Exchange Offer into the account of the Exchange Agent at DTC by electronically transmitting its acceptance of the Exchange Offer through the ATOP procedures for transfer. DTC will then verify the acceptance, execute a book-entry delivery to the Exchange Agent's account at DTC and send an agent's message to the Exchange Agent. An "agent's message" is a message, transmitted by DTC to, and received by, the Exchange Agent and forming part of a book- entry confirmation, which states that DTC has received an express acknowledgement from an organization that participates in DTC (a "participant"), tendering Initial Notes that the participant has received and agrees to be bound by the terms of the letter of transmittal and that we may enforce the agreement against the participant. A letter of transmittal need not accompany tenders effected through ATOP.

Proper Execution and Delivery of the Letter of Transmittal

        Signatures on a letter of transmittal or notice of withdrawal described under "—Withdrawal of Tenders", as the case may be, must be guaranteed by an eligible guarantor institution unless the Initial Notes tendered pursuant to the letter of transmittal are tendered for the account of an eligible guarantor institution. An "eligible guarantor institution" is one of the following firms or other entities identified in Rule 17Ad-15 under the Exchange Act (as the terms are used in Rule 17Ad-15):

        If signatures on a letter of transmittal or notice of withdrawal are required to be guaranteed, that guarantee must be made by an eligible institution.

        If the letter of transmittal is signed by the holders of Initial Notes tendered thereby, the signatures must correspond with the names as written on the face of the Initial Notes without any change whatsoever. If any of the Initial Notes tendered thereby are held by two or more holders, each holder

79


Table of Contents

must sign the letter of transmittal. If any of the Initial Notes tendered thereby are registered in different names on different Initial Notes, it will be necessary to complete, sign and submit as many separate letters of transmittal, and any accompanying documents, as there are different registrations of certificates.

        If Initial Notes that are not tendered for exchange pursuant to the Exchange Offer are to be returned to a person other than the tendering holder, certificates for those Initial Notes must be endorsed or accompanied by an appropriate instrument of transfer, signed exactly as the name of the registered owner appears on the certificates, with the signatures on the certificates or instruments of transfer guaranteed by an eligible guarantor institution.

        If the letter of transmittal is signed by a person other than the holder of any Initial Notes listed in the letter of transmittal, those Initial Notes must be properly endorsed or accompanied by a properly completed bond power, signed by the holder exactly as the holder's name appears on those Initial Notes. If the letter of transmittal or any Initial Notes, bond powers or other instruments of transfer are signed by trustees, executors, administrators, guardians, attorneys-in-fact, officers of corporations or others acting in a fiduciary or representative capacity, those persons should so indicate when signing, and, unless waived by us, evidence satisfactory to us of their authority to so act must be submitted with the letter of transmittal.

        No alternative, conditional, irregular or contingent tenders will be accepted. By executing the letter of transmittal, or facsimile thereof, the tendering holders of Initial Notes waive any right to receive any notice of the acceptance for exchange of their Initial Notes. Tendering holders should indicate in the applicable box in the letter of transmittal the name and address to which payments and/or substitute certificates evidencing Initial Notes for amounts not tendered or not exchanged are to be issued or sent, if different from the name and address of the person signing the letter of transmittal. If those instructions are not given, Initial Notes not tendered or exchanged will be returned to the tendering holder.

        All questions as to the validity, form, eligibility, including time of receipt, and acceptance and withdrawal of tendered Initial Notes will be determined by us in our absolute discretion, which determination will be final and binding. We reserve the absolute right to reject any and all tendered Initial Notes determined by us not to be in proper form or not to be tendered properly or any tendered Initial Notes our acceptance of which would, in the opinion of our counsel, be unlawful. We also reserve the right to waive, in our absolute discretion, any defects, irregularities or conditions of tender as to particular Initial Notes, whether or not waived in the case of other Initial Notes. Our interpretation of the terms and conditions of the Exchange Offer, including the terms and instructions in the letter of transmittal, will be final and binding on all parties. Unless waived, any defects or irregularities in connection with tenders of Initial Notes must be cured within the time we determine. Although we intend to notify holders of defects or irregularities with respect to tenders of Initial Notes, neither we, the Exchange Agent nor any other person will be under any duty to give that notification or shall incur any liability for failure to give that notification. Tenders of Initial Notes will not be deemed to have been made until any defects or irregularities therein have been cured or waived.

        Any holder whose Initial Notes have been mutilated, lost, stolen or destroyed will be responsible for obtaining replacement securities or for arranging for indemnification with the trustee of the Initial Notes. Holders may contact the Exchange Agent for assistance with these matters.

        In addition, we reserve the right, as set forth above under the caption "—Conditions to the Exchange Offer", to terminate the Exchange Offer. By tendering, each holder represents and acknowledges to us, among other things, that:

Withdrawal of Tenders

        Tenders of Initial Notes in the Exchange Offer may be validly withdrawn at any time prior to the Expiration Date.

        For a withdrawal of a tender to be effective, a written or facsimile transmission notice of withdrawal must be received by the Exchange Agent prior to the Expiration Date at its address set forth below under the caption "Exchange Agent". The withdrawal notice must:

        The signature on any notice of withdrawal must be guaranteed by an eligible guarantor institution, unless the Initial Notes have been tendered for the account of an eligible guarantor institution.

        Withdrawal of tenders of Initial Notes may not be rescinded, and any Initial Notes validly withdrawn will thereafter be deemed not to have been validly tendered for purposes of the Exchange Offer. Validly withdrawn Initial Notes may, however, be re-tendered by again following one of the procedures described in "—Procedures for Tendering" on or prior to the Expiration Date.

Exchange Agent

        We have appointed Wells Fargo Bank, N.A. as exchange agent in connection with this offer (the "Exchange Agent"). In such capacity, the Exchange Agent has no fiduciary duties to the holders of the Notes and will be acting solely on the basis of our directions. Holders should direct questions, requests for assistance and for additional copies of this prospectus or the letter of transmittal to the Exchange Agent addressed as follows:

Wells Fargo Bank, N.A.
Corporate Trust Operations
MAC N9303-121
P.O. Box 1517
Minneapolis, Minnesota 55480
(800) 344-5128

Fees and Expenses

        We will not make any payment to brokers, dealers or others soliciting acceptances of the Exchange Offer. We will pay certain other expenses to be incurred in connection with the Exchange Offer, including the fees and expenses of the Exchange Agent and certain accountant and legal fees.

        Holders who tender their Initial Notes for exchange will not be obligated to pay transfer taxes. If, however:

Accounting Treatment

        The Exchange Notes will be recorded at the same carrying value as the Initial Notes as reflected in our accounting records on the date of the exchange. Accordingly, we will not recognize any gain or loss for accounting purposes upon the completion of this offer. The expenses of this offer that we pay will increase our deferred financing costs in accordance with generally accepted accounting principles.

Consequences of Failure to Properly Tender Initial Notes in the Exchange Offer

        Issuance of the Exchange Notes in exchange for the Initial Notes under this offer will be made only after timely receipt by the Exchange Agent of a properly completed and duly executed letter of transmittal (or an agent's message from DTC) and the certificate(s) representing such Initial Notes (or confirmation of book-entry transfer), and all other required documents. Therefore, holders of the Initial Notes desiring to tender such Initial Notes in exchange for Exchange Notes should allow sufficient time to ensure timely delivery. We are under no duty to give notification of defects or irregularities of tenders of Initial Notes for exchange or waive any such defects or irregularities. Initial Notes that are not tendered or that are tendered but not accepted by us will, following completion of this offer, continue to be subject to the existing restrictions upon transfer thereof under the Securities

82


Table of Contents

Act, and, upon completion of this offer, certain registration rights under the registration rights agreements will terminate.

        In the event this offer is completed, we generally will not be required to register the remaining Initial Notes, subject to limited exceptions. Remaining Initial Notes will continue to be subject to the following restrictions on transfer:

        We do not currently anticipate that we will register the remaining Initial Notes under the Securities Act. To the extent that Initial Notes are tendered and accepted in connection with this offer, any trading market for remaining Initial Notes could be adversely affected. See "Risk Factors—Risk Factors Relating to the Notes and the Exchange Offer—Any Initial Notes that are not exchanged will continue to be restricted securities and may become less liquid."

        Neither we nor our board of directors make any recommendation to holders of Initial Notes as to whether to tender or refrain from tendering all or any portion of their Initial Notes pursuant to this offer. Moreover, no one has been authorized to make any such recommendation. Holders of Initial Notes must make their own decision whether to tender pursuant to this offer and, if so, the aggregate amount of Initial Notes to tender, after reading this prospectus and the letter of transmittal and consulting with their advisors, if any, based on their own financial position and requirements.

BOOK-ENTRY, DELIVERY AND FORM

The Global Notes

        Initially, the Exchange Notes will be represented by one or more registered notes in global form, without interest coupons (collectively, the "Global Notes"). The Global Notes will be deposited on the issue date with, or on behalf of, DTC and registered in the name of Cede & Co., as nominee of DTC, or will remain with the trustee as custodian for DTC.

        Except as set forth below, the Global Notes may be transferred, in whole and not in part, solely to another nominee of DTC or to a successor of DTC or its nominee. Beneficial interests in the Global Notes may not be exchanged for notes in physical, certificated form ("Certificated Notes") except in the limited circumstances described below.

        All interests in the Global Notes, including those held through Euroclear Bank S.A., as operator of the Euroclear System ("Euroclear") or Clearstream Banking, S.A. ("Clearstream"), may be subject to the procedures and requirements of DTC. Those interests held through Euroclear or Clearstream may also be subject to the procedures and requirements of such systems.

Certain Book-Entry Procedures for the Global Notes

        The descriptions of the operations and procedures of DTC, Euroclear and Clearstream set forth below are provided solely as a matter of convenience. These operations and procedures are solely within the control of the respective settlement systems and are subject to change by them from time to time. We do not take any responsibility for these operations or procedures, and investors are urged to contact the relevant system or its participants directly to discuss these matters.

        DTC has advised us that it is:

        DTC was created to hold securities for its participants (collectively, the "Participants") and facilitates the clearance and settlement of securities transactions between Participants through electronic book-entry changes to the accounts of its Participants, thereby eliminating the need for physical transfer and delivery of certificates. DTC's Participants include securities brokers and dealers, banks and trust companies, clearing corporations and certain other organizations. Indirect access to DTC's system is also available to other entities such as banks, brokers, dealers and trust companies (collectively, the "Indirect Participants") that clear through or maintain a custodial relationship with a Participant, either directly or indirectly. Investors who are not Participants may beneficially own securities held by or on behalf of DTC only through Participants or Indirect Participants.

        We expect that pursuant to procedures established by DTC (1) upon deposit of each Global Note, DTC will credit the accounts of Participants with an interest in the Global Note and (2) ownership of the Notes will be shown on, and the transfer of ownership thereof will be effected only through, records maintained by DTC (with respect to the interests of Participants) and the records of Participants and the Indirect Participants (with respect to the interests of persons other than Participants).

        The laws of some jurisdictions may require that certain purchasers of securities take physical delivery of such securities in definitive form. Accordingly, the ability to transfer interests in the Notes

84


Table of Contents

represented by a Global Note to such persons may be limited. In addition, because DTC can act only on behalf of its Participants, who in turn act on behalf of persons who hold interests through Participants, the ability of a person having an interest in Notes represented by a Global Note to pledge or transfer such interest to persons or entities that do not participate in DTC's system, or to otherwise take actions in respect of such interest, may be affected by the lack of a physical definitive security in respect of such interest.

        So long as DTC or its nominee is the registered owner of a Global Note, DTC or such nominee, as the case may be, will be considered the sole owner or holder of the Notes represented by the Global Notes for all purposes under the indenture. Except as provided below, owners of beneficial interests in a Global Note will not be entitled to have Notes represented by such Global Note registered in their names, will not receive or be entitled to receive physical delivery of Certificated Notes, and will not be considered the owners or holders thereof under the indenture for any purpose, including with respect to the giving of any direction, instruction or approval to the respective trustees thereunder. Accordingly, each holder owning a beneficial interest in a Global Note must rely on the procedures of DTC and, if such holder is not a Participant or an Indirect Participant, on the procedures of the Participant through which such holder owns its interest, to exercise any rights of a holder of Notes under the indenture or such Global Note. We understand that under existing industry practice, in the event that we request any action of holders of Notes, or a holder that is an owner of a beneficial interest in a Global Note desires to take any action that DTC, as the holder of such Global Note, is entitled to take, DTC would authorize the Participants to take such action and the Participants would authorize holders owning through such Participants to take such action or would otherwise act upon the instruction of such holders. Neither we nor the trustee will have any responsibility or liability for any aspect of the records relating to or payments made on account of Notes by DTC, or for maintaining, supervising or reviewing any records of DTC relating to such Notes.

        Payments with respect to the principal of, and premium, if any, and interest on, any Notes represented by a Global Note registered in the name of DTC or its nominee on the applicable record date will be payable by the trustee to or at the direction of DTC or its nominee in its capacity as the registered holder of the Global Note representing such Notes under the indenture. Under the terms of the indenture, we and the trustee may treat the persons in whose names the Notes, including the Global Notes, are registered as the owners thereof for the purpose of receiving payment thereon and for any and all other purposes whatsoever. Accordingly, neither we nor the trustee has or will have any responsibility or liability for the payment of such amounts to owners of beneficial interests in a Global Note (including principal, premium, if any, and interest). Payments by the Participants and the Indirect Participants to the owners of beneficial interests in a Global Note will be governed by standing instructions and customary industry practice and will be the responsibility of the Participants or the Indirect Participants and DTC.

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

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

85


Table of Contents

procedures for same-day funds settlement applicable to DTC. Euroclear participants and Clearstream participants may not deliver instructions directly to the depositories for Euroclear or Clearstream.

        Because of time zone differences, the securities account of a Euroclear or Clearstream participant purchasing an interest in a Global Note from a Participant in DTC will be credited, and any such crediting will be reported to the relevant Euroclear or Clearstream participant, during the securities settlement processing day (which must be a business day for Euroclear and Clearstream) immediately following the settlement date of DTC. Cash received in Euroclear or Clearstream as a result of sales of interests in the Global Notes by or through a Euroclear or Clearstream participant to a Participant in DTC will be received with value on the settlement date of DTC but will be available in the relevant Euroclear or Clearstream cash account only as of the business day for Euroclear or Clearstream following DTC's settlement date.

        Although DTC, Euroclear and Clearstream have agreed to the foregoing procedures to facilitate transfers of interests in the Global Notes among participants in DTC, Euroclear and Clearstream, they are under no obligation to perform or to continue to perform such procedures, and such procedures may be discontinued at any time. Neither we nor the trustee will have any responsibility for the performance by DTC, Euroclear or Clearstream or their respective participants or indirect participants of their respective obligations under the rules and procedures governing their operations.

Certificated Notes

        A Global Note is exchangeable for Certificated Notes if:

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

        Neither we nor the trustee shall be liable for any delay by DTC or any Participant or Indirect Participant in identifying the beneficial owners of the related Notes and each such person may conclusively rely on, and shall be protected in relying on, instructions from DTC for all purposes (including with respect to the registration and delivery, and the respective principal amounts, of the Exchange Notes to be issued).

MATERIAL UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

        The following discussion summarizes the material U.S. federal income tax considerations relevant to the exchange of Initial Notes for Exchange Notes pursuant to the Exchange Offer and the purchase, ownership and disposition of Notes. This summary only applies to investors that will hold their Notes as "capital assets" under the Code.

        This summary is based upon current U.S. federal income tax law, which is subject to change or differing interpretations, possibly with retroactive effect. This summary does not discuss all aspects of U.S. federal income taxation that may be important to particular investors in light of their individual circumstances, such as investors subject to special tax rules (e.g., financial institutions, insurance companies, expatriates, broker-dealers, REITs, regulated investment companies, traders in securities who elect a mark-to-market method of accounting, tax-exempt organizations, persons that will hold the Notes as a part of a straddle, hedge, conversion, constructive sale or other integrated transaction for U.S. federal income tax purposes, entities treated as partnerships for U.S. federal income tax purposes or investors therein, persons subject to alternative minimum tax or U.S. Holders (as defined below) that have a "functional currency" other than the U.S. dollar), all of whom may be subject to tax rules that differ materially from those summarized below. In addition, this summary does not discuss any U.S. federal tax laws other than U.S. federal income tax laws (such as estate or gift tax laws or the Medicare tax on certain investment income) or any foreign, state or local tax considerations. We are not planning to seek a ruling from the IRS regarding the U.S. federal income tax consequences of the purchase, ownership or disposition of the Notes. Accordingly, there can be no assurance that the IRS will not successfully challenge one or more of the conclusions stated herein. Each holder of Initial Notes considering this Exchange Offer should consult its own tax advisor regarding the tax consequences of the Exchange Offer to it, including those under state, foreign and other tax laws and other federal income tax consequences of the purchase, ownership or disposition of the Notes.

        For purposes of this summary, a "U.S. Holder" is a beneficial owner of a Note that is, for U.S. federal income tax purposes, (1) an individual who is a citizen or resident of the United States, (2) a corporation created or organized under the laws of the United States, any state thereof or the District of Columbia, (3) an estate, the income of which is subject to U.S. federal income tax regardless of its source or (4) a trust, if (a) a U.S. court can exercise primary supervision over the administration of the trust and one or more "United States persons" within the meaning of the Code control all substantial trust decisions or (b) the trust has a valid election in effect under applicable U.S. Treasury regulations to be treated as a United States person. A beneficial owner of a Note that for U.S. federal income tax purposes is an individual, corporation, estate or trust that is not a U.S. Holder is referred to herein as a "Non-U.S. Holder."

        If an entity treated as a partnership for U.S. federal income tax purposes is a beneficial owner of Notes, the tax treatment of a partner in the partnership generally will depend upon the status of the partner and the activities of the partnership. A partnership holding Notes, and partners in such a partnership, are urged to consult their tax advisors.

Exchange of the Initial Notes for Exchange Notes

        An exchange of Initial Notes for Exchange Notes pursuant to the Exchange Offer will not be treated as a taxable exchange or other taxable event for U.S. federal income tax purposes. Accordingly, there will be no U.S. federal income tax consequences to holders who exchange their Initial Notes for Exchange Notes in connection with the Exchange Offer and any such holder will have the same adjusted tax basis and holding period in the Exchange Notes as it had in the Initial Notes immediately before the exchange.

87


Table of Contents

U.S. Holders

        Stated Interest.    Interest on a Note will generally be taxable to a U.S. Holder as ordinary interest income at the time it is paid or accrued, in accordance with the U.S. Holder's regular method of tax accounting for U.S. federal income tax purposes.

        Market Discount.    If a U.S. Holder acquires a Note at a cost that is less than its stated redemption price at maturity (i.e., its stated principal amount), the amount of such difference is treated as "market discount" for U.S. federal income tax purposes, unless such difference is less than .0025 multiplied by the stated redemption price at maturity multiplied by the number of complete years to maturity (from the date of acquisition).

        Under the market discount rules of the Code, a U.S. Holder is required to treat any partial payment of principal on a Note, and any gain on the sale, exchange, retirement or other disposition of a Note, as ordinary income to the extent of the accrued market discount that has not previously been included in income. If a U.S. Holder disposes of a Note with market discount in certain otherwise nontaxable transactions, such holder must include accrued market discount as ordinary income as if the holder had sold the Note at its then fair market value.

        In general, the amount of market discount that has accrued is determined on a ratable basis. A U.S. Holder may, however, elect to determine the amount of accrued market discount on a constant yield to maturity basis. This election is made on a note-by-note basis and is irrevocable.

        With respect to Notes with market discount, a U.S. Holder may not be allowed to deduct immediately a portion of the interest expense on any indebtedness incurred or continued to purchase or to carry the Notes. A U.S. Holder may elect to include market discount in income currently as it accrues, in which case the interest deferral rule set forth in the preceding sentence will not apply. This election will apply to all debt instruments acquired by the U.S. Holder on or after the first day of the first taxable year to which the election applies and is irrevocable without the consent of the IRS. A U.S. Holder's tax basis in a Note will be increased by the amount of market discount included in the holder's income under the election.

        Amortizable Bond Premium.    If a U.S. Holder purchases a Note for an amount in excess of the stated redemption price at maturity, the holder will be considered to have purchased the Note with "amortizable bond premium" equal in amount to the excess. Generally, a U.S. Holder may elect to amortize the premium as an offset to interest income otherwise required to be included in income in respect of the Note during the taxable year, using a constant yield method similar to that described above, over the remaining term of the Note. Under Treasury Regulations, the amount of amortizable bond premium that a U.S. Holder may deduct in any accrual period is limited to the amount by which the holder's total interest inclusions on the Note in prior accrual periods exceed the total amount treated by the holder as a bond premium deduction in prior accrual periods. If any of the excess bond premium is not deductible, that amount is carried forward to the next accrual period. A U.S. Holder who elects to amortize bond premium must reduce the holder's tax basis in the Note by the amount of the premium used to offset interest income as set forth above. An election to amortize bond premium applies to all taxable debt obligations then owned and thereafter acquired by the U.S. Holder and may be revoked only with the consent of the IRS.

        Election of Constant Yield Method.    U.S. Holders may elect to include in gross income all interest that accrues on a Note, including any stated interest, market discount, de minimis market discount and unstated interest, as adjusted by amortizable bond premium, by using a constant yield prescribed in the Code and applicable Treasury Regulations. This election for a Note with amortizable bond premium will result in a deemed election to amortize bond premium for all taxable debt obligations held or subsequently acquired by the U.S. Holder on or after the first day of the first taxable year to which the election applies and may be revoked only with the consent of the IRS. Similarly, this election for a

88


Table of Contents

Note with market discount will result in a deemed election to accrue market discount in income currently for the Note and for all other debt instruments acquired by the U.S. Holder with market discount on or after the first day of the taxable year to which the election first applies, and may be revoked only with the consent of the IRS. A U.S. Holder's tax basis in a Note will be increased by each accrual of income under the constant yield election described in this paragraph.

        Sale, Exchange, Retirement, Redemption or Other Taxable Disposition of the Notes.    Upon a sale, exchange, retirement, redemption or other taxable disposition of Notes, a U.S. Holder generally will recognize gain or loss in an amount equal to the difference, if any, between the amount realized on the disposition and the U.S. Holder's adjusted tax basis in such Notes. The amount realized will include the amount of any cash and the fair market value of any property received for the Notes (other than any amount attributable to accrued but unpaid interest, which will be taxable as ordinary income (as described above under "—Stated Interest") to the extent not previously included in income). A U.S. Holder's adjusted tax basis in a Note generally will be equal to the cost of the Note to such U.S. Holder, increased by the amount of any market discount previously included in gross income and reduced by the amount of any amortizable bond premium applied to reduce, or allowed as a deduction against, interest on a Note. Any such gain or loss generally will be capital gain or loss (except with respect to accrued market discount not previously included in income, which will be taxable as ordinary income), and will be long-term capital gain or loss if the U.S. Holder's holding period for the Note is more than one year at the time of disposition. For non-corporate U.S. Holders, long-term capital gain generally will be subject to reduced rates of taxation. The deductibility of capital losses is subject to certain limitations.

Non-U.S. Holders

        Interest.    Subject to the discussion below concerning backup withholding and FATCA, all payments of interest on the Notes made to a Non-U.S. Holder will be exempt from U.S. federal income and withholding tax; provided that: (1) such Non-U.S. Holder does not own, actually or constructively, 10% or more of the capital or profits interest in the operating partnership, (2) such Non-U.S. Holder is not a controlled foreign corporation with respect to which the operating partnership is a "related person" (within the meaning of Section 864(d)(4) of the Code), (3) the beneficial owner of the Notes certifies, under penalties of perjury, to us or our paying agent on IRS Form W-8BEN or W-8BEN-E (or appropriate substitute form) that it is not a U.S. person and provides certain other information or satisfies certain other certification requirements and (4) such payments are not effectively connected with such Non-U.S. Holder's conduct of a trade or business in the United States.

        If a Non-U.S. Holder cannot satisfy the requirements described above, payments of interest will be subject to a 30% U.S. federal withholding tax, unless such Non-U.S. Holder provides us with a properly executed (1) IRS Form W-8BEN or W-8BEN-E (or appropriate substitute form) claiming an exemption from or reduction in withholding under the benefit of an applicable income tax treaty or (2) IRS Form W-8ECI (or appropriate substitute form) stating that interest paid or accrued on the Notes is not subject to withholding tax because it is effectively connected with the conduct of a trade or business in the United States and is includible in such Non-U.S. Holder's gross income.

        Sale, Exchange, Retirement, Redemption or Other Taxable Disposition of the Notes.    Subject to the discussion below concerning backup withholding and FATCA and except with respect to accrued but unpaid interest, which generally will be taxable as interest and may be subject to the rules described above under "—Non-U.S. Holders—Interest," a Non-U.S. Holder generally will not be subject to U.S. federal income or withholding tax on the receipt of payments of principal on a Note, or on any gain recognized upon the sale, exchange, retirement, redemption or other taxable disposition of a Note, unless in the case of gain (1) such gain is effectively connected with the conduct by such Non-U.S. Holder of a trade or business within the United States, in which case such gain will be taxed as described below under "—Non-U.S. Holders—Income Effectively Connected with a U.S. Trade or

89


Table of Contents

Business," or (2) such Non-U.S. Holder is an individual who is present in the United States for 183 days or more in the taxable year of disposition, and certain other conditions are met, in which case such Non-U.S. Holder will be subject to tax at 30% (or, if applicable, a lower treaty rate) on the gain derived from such disposition, which may be offset by U.S. source capital losses.

        Income Effectively Connected with a U.S. Trade or Business.    If a Non-U.S. Holder of Notes is engaged in a trade or business in the United States, and if interest on the Notes or gain realized on the sale, exchange, retirement, redemption or other taxable disposition of the Notes is effectively connected with the conduct of such trade or business, the Non-U.S. Holder generally will be subject to regular U.S. federal income tax on such income or gain in the same manner as if the Non-U.S. Holder were a U.S. Holder. If the Non-U.S. Holder is eligible for the benefits of an income tax treaty between the United States and the Non-U.S. Holder's country of residence, any "effectively connected" income or gain generally will be subject to U.S. federal income tax only if it is also attributable to a permanent establishment or fixed base maintained by the Non-U.S. Holder in the United States. In addition, if such a Non-U.S. Holder is a foreign corporation, such holder may also be subject to a branch profits tax equal to 30% (or such lower rate provided by an applicable income tax treaty) of its effectively connected earnings and profits, subject to certain adjustments. Payments of interest that are effectively connected with a U.S. trade or business will not be subject to the 30% U.S. federal withholding tax provided that the Non-U.S. Holder claims exemption from withholding. To claim exemption from withholding, the Non-U.S. Holder must certify its qualification, which generally can be done by providing a properly executed IRS Form W-8ECI (or other applicable form).

Information Reporting and Backup Withholding

        U.S. Holders.    Payments of interest on, or the proceeds of the sale, exchange, retirement, redemption or other taxable disposition of, a Note are generally subject to information reporting unless the U.S. Holder is an exempt recipient (such as a corporation). Such payments may also be subject to U.S. federal backup withholding at a 28% rate, if the recipient of such payment fails to supply a taxpayer identification number, certified under penalties of perjury, as well as certain other information or otherwise fails to establish an exemption from backup withholding. Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules will be allowed as a refund or credit against that U.S. Holder's U.S. federal income tax liability provided the required information is timely furnished to the IRS.

        Non-U.S. Holders.    A Non-U.S. Holder may be required to comply with certain certification procedures to establish that the holder is not a United States person in order to avoid backup withholding at a 28% rate, with respect to payments of interest on, or the proceeds of the sale, exchange, retirement, redemption or other disposition of, a Note. Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules will be allowed as a refund or a credit against that Non-U.S. Holder's U.S. federal income tax liability provided the required information is timely furnished to the IRS. In certain circumstances, the name and address of the beneficial owner and the amount of interest paid on a Note, as well as the amount, if any, withheld, may be reported to the IRS. Copies of these information returns may also be made available under the provisions of a specific treaty or agreement to the tax authorities of the country in which the Non-U.S. Holder resides.

FATCA

        Pursuant to Sections 1471 through 1474 of the Code ("FATCA"), withholding at a rate of 30% may be required on payments of interest on, and, beginning on January 1, 2019, gross proceeds from the sale, exchange, retirement, redemption or other taxable disposition of, a Note paid to non-U.S. financial institutions and certain other non-U.S. entities, unless they satisfy certain reporting requirements. Holders of Notes are urged to consult their tax advisors regarding to the possible implications of FATCA on their investment in Notes.

PLAN OF DISTRIBUTION

        Each broker-dealer that receives Exchange Notes in exchange for Initial Notes acquired for its own account as a result of market-making or other trading activities pursuant to the Exchange Offer must acknowledge that it will deliver a prospectus in connection with any resale of such Exchange Notes. This prospectus, as it may be amended or supplemented from time to time, may be used by a broker-dealer in connection with resales of such Exchange Notes. We have agreed that, during the period described in Section 4(a)(3) of the Securities Act and Rule 174 thereunder that is applicable to transactions by brokers or dealers with respect to Exchange Notes (the "Applicable Period"), we will use our commercially reasonable efforts to make this prospectus, as amended and supplemented, available to broker-dealers for use in connection with resales of Exchange Notes.

        We will not receive any proceeds from any sale of Exchange Notes by broker-dealers. Exchange Notes received by broker-dealers for their own account pursuant to this offer may be sold from time to time in one or more transactions in the over-the-counter market, in negotiated transactions, through the writing of options on the Exchange Notes or a combination of such methods of resale, at market prices prevailing at the time of resale, at prices related to such prevailing market prices or at negotiated prices. Any such resale may be made directly to purchasers or to or through brokers or dealers who may receive compensation in the form of commissions or concessions from any such broker-dealer and/or the purchasers of any such Exchange Notes. Any broker-dealer that resells Exchange Notes that were received by it for its own account pursuant to this offer and any broker or dealer that participates in a distribution of such Exchange Notes may be deemed to be an "underwriter" within the meaning of the Securities Act, and any profit of any such resale of Exchange Notes and any commissions or concessions received by any such persons may be deemed to be underwriting compensation under the Securities Act. The letter of transmittal states that by acknowledging that it will deliver and by delivering a prospectus, a broker-dealer will not be deemed to admit that it is an "underwriter" within the meaning of the Securities Act.

        This Exchange Offer is being made by the Issuers based upon the Issuers' understanding of interpretations by the staff of the SEC, as set forth in no-action letters issued to third parties, that the Exchange Notes issued in exchange for the Initial Notes pursuant to the Exchange Offer may be offered for resale, resold and otherwise transferred by holders thereof, without compliance with the registration and prospectus delivery provisions of the Securities Act; provided that: (i) such holder is not an "affiliate", as defined in Rule 405 under the Securities Act, of the Issuers; (ii) such Exchange Notes are acquired in the ordinary course of such holder's business; and (iii) such holder is not engaged in, does not intend to engage in, a distribution of such Exchange Notes and has no arrangement or understanding with any person to participate in a distribution, as defined in the Securities Act, of the Exchange Notes.

        However, the Issuers have not sought their own no-action letter and therefore the staff of the SEC has not considered this Exchange Offer in the context of a no-action letter. There can be no assurance that the staff of the SEC would make a similar determination with respect to the Exchange Offer as in other circumstances. If a holder of Initial Notes is an affiliate of the Issuers, acquires the Exchange Notes other than in the ordinary course of such holder's business or is engaged in or intends to engage in a distribution of the Exchange Notes or has any arrangement or understanding with respect to the distribution of the Exchange Notes to be acquired pursuant to the Exchange Offer, such holder could not rely on the applicable interpretations of the staff of the SEC and must comply with the registration and prospectus delivery requirements of the Securities Act in connection with any secondary resale transaction.

        During the Applicable Period, we will send additional copies of this prospectus and any amendment or supplement to this prospectus to any broker-dealer that requests such documents in the letter of transmittal. We have agreed to pay all expenses incident to this offer other than commissions or concessions of any brokers or dealers and will indemnify the holders of the Notes (including broker-dealers selling Exchange Notes during the Applicable Period) against certain liabilities, including liabilities under the Securities Act.

PART II

INFORMATION NOT REQUIRED IN PROSPECTUS

Item 20.    Indemnification and Limitation of Directors' and Officers' Liability

        Set forth below is a description of certain provisions of the organizational documents for each registrant, as applicable, and a description of the applicable state law for each registrant, respectively.

Maryland Registrants:

Maryland Law

        The following applies to CyrusOne, CyrusOne Finance Corp. ("FinCo"), CyrusOne LP and CyrusOne GP.

        Maryland law permits a Maryland corporation to include in its charter a provision limiting the liability of its directors and officers to the corporation and its stockholders for money damages, except for liability resulting from (i) actual receipt of an improper benefit or profit in money, property or services or (ii) active and deliberate dishonesty that is established by a final judgment and which is material to the cause of action. The charters of CyrusOne and FinCo each contain a provision that eliminates the liability of its respective directors and officers to the maximum extent permitted by Maryland law.

        The MGCL requires a corporation (unless its charter provides otherwise, which the charters of CyrusOne and FinCo do not) to indemnify a director or officer who has been successful, on the merits or otherwise, in the defense of any proceeding to which he or she is made a party by reason of his or her service in that capacity. The MGCL permits a corporation to indemnify its present and former directors and officers, among others, against judgments, penalties, fines, settlements and reasonable expenses actually incurred by them in connection with any proceeding to which they may be made or threatened to be made a party by reason of their service in those or other capacities unless it is established that:

        Under the MGCL, a Maryland corporation may not indemnify a director or officer in a suit by or in the right of the corporation in which the director or officer was adjudged liable to the corporation or in a proceeding in which the director or officer was adjudged liable on the basis that personal benefit was improperly received. A court may order indemnification if it determines that the director or officer is fairly and reasonably entitled to indemnification, even though the director or officer did not meet the prescribed standard of conduct or was adjudged liable on the basis that personal benefit was improperly received. However, indemnification for an adverse judgment in a suit by or in the right of the corporation or for a judgment of liability on the basis that personal benefit was improperly received, is limited to expenses.

II-1


Table of Contents

        In addition, the MGCL permits a Maryland corporation to advance reasonable expenses to a director or officer upon the corporation's receipt of:

        CyrusOne's charter authorizes it to obligate CyrusOne, and CyrusOne's bylaws obligate it, to the maximum extent permitted by Maryland law in effect from time to time, to indemnify and, without requiring a preliminary determination of the ultimate entitlement to indemnification, pay or reimburse reasonable expenses in advance of final disposition of a proceeding to:

        CyrusOne's charter and bylaws also permit it to indemnify and advance expenses to any person who served a predecessor of CyrusOne in any of the capacities described above and to any employee or agent of CyrusOne or a predecessor of CyrusOne.

        CyrusOne has entered into indemnification agreements with each of its directors and executive officers that provide for indemnification to the maximum extent permitted by Maryland law.

        FinCo's charter and bylaws obligate FinCo, to the maximum extent permitted by Maryland law in effect from time to time, to indemnify and, without requiring a preliminary determination of the ultimate entitlement to indemnification, pay or reimburse reasonable expenses in advance of final disposition of a proceeding to:

        FinCo's charter and bylaws also permit it to indemnify and advance expenses to any person who served a predecessor of FinCo in any of the capacities described above and to any employee or agent of FinCo or a predecessor of FinCo.

        In addition, the partnership agreement of CyrusOne LP provides that CyrusOne, its directors, officers and employees, CyrusOne GP, as general partner, and its trustees, officers and employees, employees of our operating partnership and any other persons that the general partner may designate are indemnified to the fullest extent permitted by law, but that CyrusOne LP shall not indemnify any indemnitee for any liability (i) if it is established that the act or omission of the indemnitee constituted fraud, intentional harm or gross negligence on the part of the indemnitee, (ii) arising from an action or proceeding initiated by the indemnitee (other than to enforce such indemnitee's rights to

II-2


Table of Contents

indemnification or advance of expenses) or (iii) with respect to any claim as to which the indemnitee is found to be liable to CyrusOne LP.

        CyrusOne GP's declaration of trust contains a provision that eliminates the liability of its trustees and officers to the maximum extent permitted by Maryland law, which limits the liability of trustees and officers to the same extent as described above for directors and officers of CyrusOne and FinCo. CyrusOne GP's declaration of trust obligates it, to the maximum extent permitted by Maryland law in effect from time to time, to indemnify and, without requiring a preliminary determination of the ultimate entitlement to indemnification, pay or reimburse reasonable expenses in advance of final disposition of a proceeding to any present or former trustee or officer of CyrusOne GP against any claim or liability to which such person may become subject by reason of such status, except for liability for such person's gross negligence or intentional harm. CyrusOne GP's declaration of trust also permits it to indemnify and advance expenses to any person who served a predecessor of CyrusOne GP in any of the capacities described above and to any employee or agent of CyrusOne GP or a predecessor of CyrusOne GP.

        Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers or persons controlling our company pursuant to the foregoing provisions, we have been informed that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.

Delaware Registrants:

Delaware General Corporate Law

        The following applies to CyrusOne TRS Inc., a Delaware registered company ("Cyrus TRS"). The following description is intended only as a summary and is qualified in its entirety by reference to the Certificate of Incorporation of CyrusOne TRS Inc. (the "TRS certificate of incorporation"), the Bylaws of CyrusOne TRS Inc. (the "TRS bylaws"), and the Delaware General Corporate Law (the "DGCL").

        Pursuant to the DGCL, a corporation may indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of such corporation) by reason of the fact that such person is or was a director, officer, employee or agent of such corporation, or is or was serving at the request of such corporation in such capacity for another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys' fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with such action, suit or proceeding, if such person acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the best interests of such corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe his or her conduct was unlawful.

        The DGCL also permits indemnification by a corporation under similar circumstances for expenses (including attorneys' fees) actually and reasonably incurred by such persons in connection with the defense or settlement of an action by or in the right of such corporation, except that no indemnification shall be made in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable to such corporation unless and only to the extent that the Delaware Court of Chancery or the court in which such action or suit was brought shall determine upon application that such person is fairly and reasonably entitled to indemnity for such expenses which such court shall deem proper.

        To the extent that a present or former director or officer is successful in the defense of such an action, suit or proceeding (or of any claim, issue or matter therein), the corporation is required by the

II-3


Table of Contents

DGCL to indemnify such person for actual and reasonable expenses (including attorneys' fees) incurred thereby.

        Expenses (including attorneys' fees) incurred by a director or officer in defending any civil, criminal, administrative or investigative action, suit or proceeding may be paid (on terms and conditions satisfactory to the corporation) in advance of the final disposition of such action, suit or proceeding upon receipt of an undertaking by or on behalf of such person to repay such amount if it is ultimately determined that such person is not entitled to be so indemnified.

        The DGCL provides that the indemnification and advancement of expenses described above shall not be deemed exclusive of other indemnification or advancement of expenses that may be granted by a corporation pursuant to its by-laws, a disinterested director vote, a stockholder vote, an agreement or otherwise.

        The DGCL also provides corporations with the power to purchase and maintain insurance on behalf of any person who is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation in a similar capacity for another corporation, partnership, joint venture, trust or other enterprise, against any liability asserted against him or her in any such capacity, or arising out of his or her status as such, whether or not the corporation would have the power to indemnify him or her against such liability as described above.

        Cyrus TRS is organized as a corporation under Delaware law and is subject to the provisions of the DGCL. The TRS certificate of incorporation and TRS bylaws provide that Cyrus TRS shall, to the fullest extent permitted by applicable law, indemnify and hold harmless each person (each, a "TRS Covered Person") who is or was or whose testator or intestate was a director, officer, employee or agent of Cyrus TRS or of any corporation (each, a "Predecessor Corporation") that consolidated or merged with or into Cyrus TRS, or who is or was or whose testator or intestate was a fiduciary of or otherwise rendered services to any employee benefit plan of Cyrus TRS. Additionally, Cyrus TRS may, to the fullest extent permitted by applicable law, indemnify and hold harmless each person (each, a "TRS Affiliate Covered Person") who is or was or whose testate or intestate was serving at the request of Cyrus TRS as a director, officer, employee or agent of another corporation, or of a partnership, joint venture, trust or other enterprise or who at the request of Cyrus TRS or its affiliate was serving as a fiduciary of or otherwise rendering services to any employee benefit plan of or relating to such affiliate.

        The TRS certificate of incorporation and the TRS bylaws also provide that Cyrus TRS shall, to the fullest extent not prohibited by applicable law, pay the expenses (including attorneys' fees) incurred by a TRS Covered Person or of a TRS Affiliate Covered Person in defending any proceeding in advance of its final disposition; provided, however, that, to the extent required by law, such payment of expenses in advance of the final disposition of the proceeding shall be made only upon receipt of an undertaking by, or, with TRS approval, on behalf of, such TRS Covered Person or TRS Affiliate Covered Person, to repay all amounts advanced if it should be ultimately determined that such person is not entitled to be indemnified.

        Furthermore, pursuant to the TRS certificate of incorporation, as permitted under the DGCL, a director of Cyrus TRS shall not be personally liable to Cyrus TRS or its stockholders for monetary damages for breach of his or her fiduciary duty as a director, except for liability (1) for any breach of his or her duty of loyalty to Cyrus TRS or its stockholders, (2) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (3) under Section 174 of the DGCL or (4) for any transaction from which he or she derived an improper personal benefit.

        The DGCL permits and Cyrus TRS has, liability insurance for the benefit of its directors and officers.

        (b)   The undersigned registrants hereby undertake that, for the purposes of determining any liability under the Securities Act of 1933, each filing of the registrants' annual report pursuant to section 13(a) or section 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

Table of Contents

Act of 1934) that is incorporated by reference in the registration shall be deemed to be a new registration statement relating to the securities offering therein, and the offering of such securities at that time shall be deemed to be the initial bona 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 provisions described in Item 20, 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 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 and will be governed by the final adjudication of such issue.

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