As filed pursuant to 424(b)(3)
Under the Securities Act of 1933
Registration No. 333-207398

We are jointly offering to exchange up to $1,780,000,000 aggregate principal amount of our 6.00% Senior Notes due 2023 (the “2023 Exchange Notes”) and 6.375% Senior Notes due 2025 (the “2025 Exchange Notes,” and together with the 2023 Exchange Notes, the “Exchange Notes”) for an equal amount of our outstanding, unregistered 6.00% Senior Notes due 2023 (the “2023 Outstanding Notes”) and 6.375% Senior Notes due 2025 (the “2025 Outstanding Notes,” and together with the 2023 Outstanding Notes, the “Outstanding Notes”), respectively. The term “Notes” refers to both the Outstanding Notes and the Exchange Notes. We refer to the offer to exchange the Exchange Notes for the Outstanding Notes as the “exchange offer” in this prospectus. The Exchange Notes will be identical in all material respects to the Outstanding Notes of the applicable series, except that the Exchange Notes are registered under the Securities Act of 1933, as amended (the “Securities Act”), and except that the transfer restrictions, registration rights and additional interest provisions relating to the Outstanding Notes will not apply to the Exchange Notes.

See the “Description of 2023 Notes” and “Description of 2025 Notes” section beginning on page 90 for more information about the Exchange Notes to be issued in this exchange offer.

Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities or passed upon the adequacy or the accuracy of this prospectus. Any representation to the contrary is a criminal offense.

Zayo Group, LLC (the “Company”), Zayo Capital, Inc. (“Zayo Capital”) and the current subsidiaries of the Company that have guaranteed the notes (the “Guarantors”) have jointly filed a registration statement with the Securities and Exchange Commission (the “SEC”) on Form S-4 to register the exchange offer contemplated in this prospectus. This prospectus is part of that registration statement. As allowed by the SEC’s rules, this prospectus does not contain all of the information you can find in the registration statement or the exhibits to the registration statement. This prospectus contains summaries of the material terms and provisions of certain documents and in each instance we refer you to the copy of such document filed as an exhibit to the registration statement.

We file annual and quarterly reports and other information with the SEC. The registration statement (including the exhibits and schedules thereto) and the periodic reports and other information filed by Zayo Group, LLC and Zayo Capital, Inc. with the SEC may be inspected and copied at the SEC’s Public Reference Room at 100 F Street, N.E., Washington, D.C. 20549. Please call the SEC at 1-800-SEC-0330 for further information on the Public Reference Room. Such information may also be accessed electronically by means of the SEC’s homepage on the Internet at www.sec.gov, which contains reports and other information regarding registrants, including Zayo Group, LLC, that file electronically with the SEC. The information contained on the SEC website is not incorporated by reference in this prospectus and you should not consider that information a part of this prospectus.

You may also obtain this information without charge by writing or telephoning us at the following address and telephone number:

In order to ensure timely delivery, you must request the information no later than five business days before the expiration of the exchange offer.

Pursuant to the indentures governing the Notes, Zayo Group, LLC and Zayo Capital, Inc. have agreed, whether or not subject to the informational requirements of the Exchange Act, to provide the trustee and holders of the Notes with annual, quarterly and other reports at the times and containing in all material respects the information specified in Sections 13 and 15(d) of the Exchange Act and to file such reports with the SEC.

We have included Adjusted EBITDA as a financial measure in this prospectus. Adjusted EBITDA is not defined under generally accepted accounting principles in the United States, or GAAP. We define Adjusted EBITDA as earnings/(loss) from continuing operations before interest, income taxes, depreciation and amortization (“EBITDA”) adjusted to exclude acquisition or disposal-related transaction costs, losses on extinguishment of debt, stock-based compensation, unrealized foreign currency gains (losses) on intercompany loans, and non-cash income (loss) on equity and cost method investments. We use Adjusted EBITDA to evaluate operating performance, and this financial measure is among the primary measures used by management for planning and forecasting for future periods. We believe that the presentation of Adjusted EBITDA is relevant and useful for investors because it allows investors to view results in a manner similar to the method used by management and facilitates comparison of our results with the results of other companies that have different financing and capital structures.

We also monitor Adjusted EBITDA because our subsidiaries have debt covenants that restrict their borrowing capacity that are based on a leverage ratio, which utilizes a modified EBITDA, as defined in our Credit Agreement (as defined below) and the indentures governing our outstanding notes. The modified EBITDA is consistent with our definition of Adjusted EBITDA; however, it includes the pro forma Adjusted EBITDA of and expected cost synergies from the companies acquired by us during the quarter for which the debt compliance certification is due. Adjusted EBITDA results, along with other quantitative and qualitative information, are also utilized by management and our compensation committee for purposes of determining bonus payouts to employees.

Adjusted EBITDA has limitations as an analytical tool and should not be considered in isolation from, or as a substitute for, analysis of our results as reported under GAAP. For example, Adjusted EBITDA:

Our computation of Adjusted EBITDA may not be comparable to other similarly titled measures computed by other companies because all companies do not calculate Adjusted EBITDA in the same fashion.

Because we have acquired numerous entities since our inception and incurred transaction costs in connection with each acquisition, borrowed money in order to finance our operations and acquisitions, and used capital and intangible assets in our business, and because the payment of income taxes is necessary if we generate taxable income after the utilization of our net operating loss carryforwards, any measure that excludes these items has material limitations. As a result of these limitations, these measures should not be considered as a measure of discretionary cash available to us to invest in the growth of our business or as a measure of our liquidity. See “Selected Historical Consolidated Financial Information” for a quantitative reconciliation of Adjusted EBITDA to net income/(loss).

SUMMARY OF THE EXCHANGE OFFER

We are jointly offering to exchange up to $1,780,000,000 aggregate principal amount of our 6.00% Senior Notes due 2023 (the “2023 Exchange Notes”) and 6.375% Senior Notes due 2025 (the “2025 Exchange Notes”) for an equal amount of our outstanding, unregistered 6.00% Senior Notes due 2023 (the “2023 Outstanding Notes” and together with the 2023 Exchange Notes, the “2023 Notes”) and 6.375% Senior Notes due 2025 (the “2025 Outstanding Notes” and together with the 2025 Exchange Notes, the “2025 Notes”), respectively.

The following is a summary of the principal terms of the exchange offer. A more detailed description is contained in the section “The Exchange Offer.” The term “Outstanding Notes” refers collectively to our outstanding 6.00% Senior Notes due 2023 and 6.375% Senior Notes due 2025. The term “Exchange Notes” refers collectively to our 6.00% Senior Notes due 2023 and 6.375% Senior Notes due 2025 offered by this prospectus, which have been registered under the Securities Act of 1933, as amended (the “Securities Act”). The term “Notes” refers collectively to the Outstanding Notes and the Exchange Notes offered in the exchange offer. The term “Indentures” refers to the indentures that govern both the Outstanding Notes and the Exchange Notes.

The Exchange Offer

We are offering to exchange $1,000 principal amount of Exchange Notes, which have been registered under the Securities Act, for each $1,000 principal amount of each applicable series of Outstanding Notes, subject to a minimum exchange of $2,000. As of the date of this prospectus, $1,780,000,000 aggregate principal amount of the Outstanding Notes is outstanding, consisting of:

$1,430,000,000 aggregate principal amount of 2023 Outstanding Notes; and

$350,000,000 aggregate principal amount of 2025 Outstanding Notes.

We issued the Outstanding Notes in private transactions for resale pursuant to Rule 144A and Regulation S under the Securities Act. The terms of the Exchange Notes are substantially identical to the terms of the Outstanding Notes of the applicable series, except that provisions relating to transfer restrictions, registration rights, and rights to increased interest in addition to the stated interest rate on the Outstanding Notes (“Additional Interest”) will not apply to the Exchange Notes.

In order to exchange your Outstanding Notes for Exchange Notes, you must properly tender them at or prior to the expiration of the exchange offer.

Expiration Time

The exchange offer will expire at 5:00 p.m., New York City time, on November 18, 2015, unless the exchange offer is extended, in which case the expiration time will be the latest date and time to which the exchange offer is extended. See “The Exchange Offer—Terms of the Exchange Offer; Expiration Time.”

Procedures for Tendering Outstanding Notes

You may tender your Outstanding Notes through book-entry transfer in accordance with The Depository Trust Company’s Automated Tender Offer Program, known as ATOP. If you wish to accept the exchange offer, you must:

•

complete, sign, and date the accompanying letter of transmittal, or a facsimile of the letter of transmittal, in accordance with the instructions contained in the letter of transmittal, and mail or otherwise deliver the letter of transmittal, together with your Outstanding Notes, to the exchange agent at the address set forth under “The Exchange Offer—The Exchange Agent”; or

•

arrange for The Depository Trust Company to transmit to the exchange agent certain required information, including an agent’s message forming part of a book-entry transfer in which you agree to be bound by the terms of the letter of transmittal, and transfer the Outstanding Notes being tendered into the exchange agent’s account at The Depository Trust Company.

You may tender your Outstanding Notes for the applicable series of Exchange Notes in whole or in part in minimum denominations of $2,000 and integral multiples of $1,000 in excess of $2,000.

See “The Exchange Offer—How to Tender Outstanding Notes for Exchange.”

Guaranteed Delivery Procedures

If you wish to tender your Outstanding Notes and time will not permit your required documents to reach the exchange agent by the expiration time, or the procedures for book-entry transfer cannot be completed by the expiration time, you may tender your Outstanding Notes according to the guaranteed delivery procedures described in “The Exchange Offer—Guaranteed Delivery Procedures.”

Special Procedures for Beneficial Owners

If you beneficially own Outstanding Notes registered in the name of a broker, dealer, commercial bank, trust company, or other nominee and you wish to tender your Outstanding Notes in the exchange offer, you should contact the registered holder promptly and instruct it to tender on your behalf. See “The Exchange Offer—How to Tender Outstanding Notes for Exchange.”

Withdrawal of Tenders

You may withdraw your tender of Outstanding Notes at any time at or prior to the expiration time by delivering a written notice of withdrawal to the exchange agent in conformity with the procedures discussed under “The Exchange Offer—Withdrawal Rights.”

Acceptance of Outstanding Notes and Delivery of Exchange Notes

We will accept any and all Outstanding Notes that are properly tendered in the exchange offer and not withdrawn at or prior to the expiration time promptly upon the expiration time. The Exchange Notes issued pursuant to the exchange offer will be delivered promptly upon expiration of the exchange offer, and any tendered Outstanding Notes that are not accepted for exchange will be returned

to the tendering holder promptly upon the expiration or termination of the exchange offer. See “The Exchange Offer—Terms of the Exchange Offer; Expiration Time.”

Registration Rights Agreements

We are making the exchange offer pursuant to three separate registration rights agreements that we entered into with the initial purchasers of the Outstanding Notes on January 23, 2015 and March 9, 2015, with respect to the 2023 Exchange Notes, and May 6, 2015, with respect to the 2025 Exchange Notes (the “Registration Rights Agreements”).

Resales of Exchange Notes

We believe that the Exchange Notes issued in the exchange offer may be offered for resale, resold, or otherwise transferred by you without compliance with the registration and prospectus delivery requirements of the Securities Act, provided that:

•

you are not an “affiliate” of ours;

•

the Exchange Notes you receive pursuant to the exchange offer are being acquired in the ordinary course of your business;

•

you have no arrangement or understanding with any person to participate in the distribution of the Exchange Notes issued to you in the exchange offer;

•

if you are not a broker-dealer, you are not engaged in, and do not intend to engage in, a distribution of the Exchange Notes issued in the exchange offer; and

•

if you are a broker-dealer, you will receive the Exchange Notes for your own account, the Outstanding Notes were acquired by you as a result of market-making or other trading activities, and you will deliver a prospectus when you resell or transfer any Exchange Notes issued in the exchange offer. See “Plan of Distribution” for a description of the prospectus delivery obligations of broker-dealers in the exchange offer.

If you do not meet these requirements, your resale of the Exchange Notes must comply with the registration and prospectus delivery requirements of the Securities Act.

Our belief is based on interpretations by the staff of the SEC, as set forth in no-action letters issued to third parties. The staff of the SEC has not considered this exchange offer in the context of a no-action letter, and we cannot assure you that the staff of the SEC would make a similar determination with respect to this exchange offer.

If our belief is not accurate and you transfer an exchange note without delivering a prospectus meeting the requirements of the federal securities laws or without an exemption from these laws, you may incur liability under the federal securities laws. We do not and will not assume, or indemnify you against, this liability.

See “The Exchange Offer—Consequences of Exchanging Outstanding Notes.”

Consequences of Failure to Exchange Your Outstanding Notes

If you do not exchange your Outstanding Notes in the exchange offer, your Outstanding Notes will continue to be subject to the restrictions on transfer provided in the Outstanding Notes and in the Indentures. In general, the Outstanding Notes may not be offered or sold unless registered or sold in a transaction exempt from registration under the Securities Act and applicable state securities laws. If a substantial amount of the Outstanding Notes is exchanged for a like amount of the Exchange Notes, the liquidity and the trading market for your untendered Outstanding Notes could be adversely affected. See “The Exchange Offer—Consequences of Failure to Exchange Outstanding Notes.”

Exchange Agent

The exchange agent for the exchange offer is The Bank of New York Mellon Trust Company, N.A. For additional information, see “The Exchange Offer—The Exchange Agent” and the accompanying letter of transmittal.

Material U.S. Federal Income Tax Considerations

The exchange of your Outstanding Notes for Exchange Notes will not be a taxable exchange for United States federal income tax purposes. You should consult your own tax advisor as to the tax consequences to you of the exchange offer, as well as tax consequences of the ownership and disposition of the Exchange Notes. For additional information, see “Material U.S. Federal Income Tax Considerations.”

SUMMARY OF THE TERMS OF THE EXCHANGE NOTES

The terms of the Exchange Notes are substantially the same as the Outstanding Notes, except that provisions relating to transfer restrictions, registration rights, and Additional Interest will not apply to the Exchange Notes. The following is a summary of the principal terms of the Exchange Notes. A more detailed description is contained in the sections “Description of 2023 Notes” and “Description of 2025 Notes” in this prospectus.

Issuers

Zayo Group, LLC and Zayo Capital, Inc., as co-issuers.

$1,430,000,000 aggregate principal amount of 6.00% Senior Notes due 2023.

$350,000,000 aggregate principal amount of 6.375% Senior Notes due 2025.

We pay interest on the 2025 Exchange Notes semi-annually in arrears on May 15 and November 15 of each year to holders of record on the May 1 or November 1 immediately preceding the interest payment date.

Interest on the Exchange Notes will accrue from the most recent date to which interest has been paid on the Outstanding Notes of the applicable series, if any.

We may redeem the 2023 Exchange Notes and the 2025 Exchange Notes, in whole or in part, on or after April 1, 2018 and May 15, 2020, respectively, at the applicable redemption prices set forth in this prospectus under the headings “Description of 2023 Notes—Optional Redemption” and “Description of 2025 Notes—Optional Redemption,” plus accrued and unpaid interest.

We may redeem the 2023 Exchange Notes and the 2025 Exchange Notes, in whole or in part, at any time before April 1, 2018 and May 15, 2020, respectively, at a redemption price equal to 100% of their principal amount plus accrued and unpaid interest and a “make-whole” premium.

In addition, using the proceeds of certain equity offerings, we may redeem (i) at any time prior to April 1, 2018, up to 40% of the 2023 Exchange Notes at a redemption price equal to 106.00% of their principal amount, plus accrued and unpaid interest and additional interest and (ii) at any time prior to May 15, 2018, up to 40% of the 2025 Exchange Notes at a redemption price equal to 106.375% of their principal amount, plus accrued and unpaid interest.

See “Description of 2023 Notes—Optional Redemption” and “Description of 2025 Notes—Optional Redemption,”

Subsidiary Guarantees

The Exchange Notes will be fully and unconditionally guaranteed, jointly and severally, on a senior unsecured basis by all of our current and future domestic restricted subsidiaries and any other restricted subsidiaries of ours that guarantee any indebtedness of the Issuers or any guarantor (the “Guarantors”). We refer to the guarantees of the Exchange Notes as the “Guarantees.”

Ranking

The Exchange Notes and the Guarantees will be general unsecured obligations of the Issuers and each Guarantor and will rank:

•

equally in right of payment with all existing and future senior unsecured indebtedness of the Issuers and the Guarantors;

•

senior in right of payment to all future indebtedness of the Issuers and the Guarantors that is by its terms expressly subordinated in right of payment to the Exchange Notes or the applicable Guarantee, if any;

•

effectively subordinated to the Issuers’ and the Guarantors’ secured indebtedness, including the indebtedness under the Credit Facilities (as defined below), to the extent of the value of the collateral securing such indebtedness; and

•

structurally subordinate in right of payment to all future indebtedness and other liabilities of future subsidiaries of the Issuers and the Guarantors that do not guarantee the Exchange Notes, which will consist only of unrestricted subsidiaries and foreign subsidiaries that do not guarantee any of our other indebtedness.

As of June 30, 2015:

•

the Notes were effectively subordinated in right of payment to $32.7 million in capital lease obligations to the extent of the value of the collateral securing such capital lease obligations;

•

the Notes were effectively subordinated in right of payment to $1,646.8 million of senior secured indebtedness consisting of indebtedness under the Term Loan Facility (as defined below) to the extent of the value of the collateral; and

•

we would have had an additional $440.8 million available for borrowing under the Revolver (as defined below), subject to certain conditions, all of which would be effectively senior to the Exchange Notes if borrowed to the extent of the value of the collateral.

For the year ended June 30, 2015, the non-guarantor subsidiaries of the Company (other than Zayo Capital, Inc.) generated 12% of the Company’s consolidated net revenue. In addition, as of June 30, 2015, these non-guarantor subsidiaries of the Company held 13% of the

Company’s total consolidated assets and had $151.3 million in liabilities (excluding inter-company liabilities).

Change of Control

If we experience a change of control, we will be required to make an offer to repurchase the Notes at a price equal to 101% of the outstanding principal amount of the Notes plus accrued and unpaid interest to the date of repurchase. See “Description of 2023 Notes—Repurchase at the Option of Holders—Change of Control” and “Description of 2025 Notes—Repurchase at the Option of Holders—Change of Control.”

Certain Covenants

The Indentures governing the Notes restrict our ability and the ability of our restricted subsidiaries to, among other things:

•

incur additional indebtedness and issue preferred stock;

•

pay dividends or make other distributions with respect to any equity interests or make certain investments or other restricted payments;

•

create liens;

•

sell assets;

•

incur restrictions on the ability of our restricted subsidiaries to pay dividends or make other payments to us;

•

consolidate or merge with or into other companies or transfer all or substantially all of our assets;

•

engage in transactions with affiliates; and

•

enter into sale and leaseback transactions.

These covenants are subject to a number of important qualifications and exceptions. See “Description of 2023 Notes—Certain Covenants” and “Description of 2025 Notes—Certain Covenants.”

Risk Factors

See “Risk Factors” for a discussion of certain risks you should carefully consider.

The Exchange Notes involve substantial risks similar to those associated with the Outstanding Notes. If any of the following risks actually occur, our business, financial condition or operating results could be materially adversely affected, which, in turn, could adversely affect our ability to pay interest or principal on the notes or otherwise fulfill our obligations under the indentures governing the notes.

We cannot assure you that an active trading market for the Exchange Notes will exist if you desire to sell the Exchange Notes.

There is no existing public market for the Outstanding Notes or the Exchange Notes. We do not intend to have the Exchange Notes listed on a national securities exchange or to arrange for quotation on any automated dealer quotation systems. Therefore, we cannot assure you as to the development or liquidity of any trading market for the Exchange Notes. The liquidity of any market for the Exchange Notes will depend on a number of factors, including:

Historically, the market for non-investment grade debt has been subject to disruptions that have caused substantial volatility in the prices of securities similar to the Exchange Notes. The market, if any, for the Exchange Notes may face similar disruptions that may adversely affect the prices at which you could sell your Exchange Notes. Therefore, you may not be able to sell your Exchange Notes at a particular time and the price that you receive when you sell may not be favorable.

You may have difficulty selling any Outstanding Notes that you do not exchange.

If you do not exchange your Outstanding Notes for Exchange Notes in the exchange offer, you will continue to hold Outstanding Notes subject to restrictions on their transfer. Those transfer restrictions are described in the Indentures and in the legend contained on the Outstanding Notes, and arose because we originally issued the Outstanding Notes under an exemption from the registration requirements of the Securities Act.

In general, you may offer or sell your Outstanding Notes only if they are registered under the Securities Act and applicable state securities laws, or if they are offered and sold under an exemption from those requirements. We do not currently intend to register the Outstanding Notes under the Securities Act or any state securities laws. If a substantial amount of the Outstanding Notes is exchanged for a like amount of the Exchange Notes issued in the exchange offer, the liquidity of your Outstanding Notes could be adversely affected. See “The Exchange Offer—Consequences of Failure to Exchange Outstanding Notes” for a discussion of additional consequences of failing to exchange your Outstanding Notes.

We have consistently generated net losses since our inception and such losses may continue in the future.

We have consistently generated net losses since our inception and such losses may continue in the future. These net losses primarily have been driven by significant depreciation, amortization, interest expense, and

stock-based compensation. During Fiscal 2015, we had depreciation and amortization expense of $406.2 million, stock-based compensation expense of $200.7 million, and interest expense of $214.0 million. At June 30, 2015, we had $3,785.1 million of total debt (including capital lease obligations and before any unamortized discounts, premiums and debt issuance costs). We cannot assure you that we will generate net income in the future.

Since our inception, we have used more cash than we have generated from operations, and we may continue to do so.

Since our inception, we have consistently consumed our entire positive cash flow generated from operating activities with our investing activities. Our investing activities have consisted principally of the acquisition of businesses as well as material additions to property and equipment. We have funded the excess of cash used in investing activities over cash provided by operating activities with proceeds from equity contributions and equity and debt issuances.

We intend to continue to invest in expanding our fiber network and our business and pursuing acquisitions that we believe provide an attractive return on our capital. These investments may continue to exceed the amount of cash flow available from operations after debt service requirements. To the extent that our investments exceed our cash flow from operations, we plan to rely on potential future debt or equity issuances, which could increase interest expense or dilute the interest of Holdings’ stockholders, as well as cash on hand and borrowings under our revolving credit facility. We cannot assure you, however, that we will be able to obtain or continue to have access to sufficient capital on reasonable terms, or at all, to successfully grow our business.

We are highly dependent on our management team and other key employees, many of whom own equity that was previously illiquid but became liquid as a result of Holdings’ initial public offering.

We expect that our continued success will largely depend upon the efforts and abilities of members of our management team and other key employees. Our success also depends upon our ability to identify, attract, develop, and retain qualified employees. None of the executive management team except for Mr. Caruso is bound by an employment agreement with us. If we lost members of our management team or other key employees, it would likely have a material adverse effect on our business. As announced on December 26, 2014, Dan Caruso, Chief Executive Officer and Chairman of the Board of Directors of the Company is undergoing treatment for prostate cancer. Mr. Caruso was diagnosed with and treated for prostate cancer in 2013 and recent tests have revealed that trace amounts of the cancer remain. Mr. Caruso is continuing to fulfill his responsibilities as the Company’s CEO and Chairman on a full-time basis with no interruption. At this time, no organizational changes related to Mr. Caruso’s cancer treatment are planned or anticipated.

All of our officers and many of our key management and employees have had a significant portion of their compensation paid in equity. The liquidity provided by Holdings’ initial public offeing and subsequent equity offerings in many cases represents material wealth of our officers and key management employees that may impact retention and focus of existing key employees.

Our revenue is relatively concentrated among a small number of customers, and the loss of any of these customers could significantly harm our business, financial condition, results of operations, and cash flows.

Our largest single customer, based on recurring revenue, accounted for approximately 6% of our revenue during Fiscal 2015, and total revenues from our top ten customers accounted for approximately 27% of our revenue during Fiscal 2015. We currently depend, and expect to continue to depend, upon a relatively small number of customers for a significant percentage of our revenue. Many of these customers are also competitors for some or all of our service offerings. Our customer contracts typically have terms of one to twenty years. Our customers may elect not to renew these contracts. Furthermore, our customer contracts are terminable for cause if we breach a material provision of the contract. We may face increased competition and pricing pressure as our customer contracts become subject to renewal. Our customers may negotiate renewal of their contracts at lower

rates, for fewer services or for shorter terms. Many of our customers are in the telecommunications industry, which is undergoing consolidation. To the extent that two or more of our customers combine, they may be able to use their greater size to negotiate lower prices from us and may purchase fewer services from us, especially if their networks overlap. If we are unable to successfully renew our customer contracts on commercially acceptable terms, or if our customer contracts are terminated, our business could suffer.

We are also subject to credit risk associated with the concentration of our accounts receivable from our key customers. If one or more of these customers were to become bankrupt, insolvent or otherwise were unable to pay for the services provided by us, we may incur significant write-offs of accounts receivable or incur impairment charges.

We have numerous customer orders for connections, including contracts with multiple national wireless carriers to build out additional towers. If we are unable to satisfy new orders or build our network according to contractually specified deadlines, we may incur penalties or suffer the loss of revenue.

Future acquisitions are a component of our strategic plan, and will include integration and other risks that could harm our business.

We have grown rapidly and intend to continue to acquire complementary businesses and assets, and some of these acquisitions may be large or in new geographic areas where we do not currently operate. This exposes us to the risk that when we evaluate a potential acquisition target we over-estimate the target’s value and, as a result, pay too much for it. We also cannot be certain that we will be able to successfully integrate acquired assets or the operations of the acquired entity with our existing operations. Businesses and assets that we have acquired or may acquire in the future may be subject to unknown or contingent liabilities for which we may have limited or no recourse against the sellers. While we usually require the sellers to indemnify us with respect to breaches of representations and warranties that survive, such indemnification is often limited and subject to various materiality thresholds, a significant deductible or an aggregate cap on losses. As a result, there is no guarantee that we will recover any amounts with respect to losses due to breaches by the sellers of their representations and warranties. In addition, the total amount of costs and expenses that we may incur with respect to liabilities associated with acquired properties and entities may exceed our expectations, which may adversely affect our operating results and financial condition.

We have previously engaged in and may continue to engage in large acquisitions, such as the AboveNet and Latisys acquisitions, which could be much more difficult to integrate. Difficulties with integration could cause material customer disruption and dissatisfaction, which could in turn increase churn and reduce new sales. Additionally, we may not be able to integrate acquired businesses in a manner that permits us to realize the cost synergies we anticipate in the time, manner, or amount we currently expect, or at all. Our actual cost synergies, cost savings, growth opportunities, and efficiency and operational benefits resulting from any acquisition may be lower and may take longer to realize than we currently expect. In addition, some recently acquired companies have had Adjusted EBITDA margins that were lower than ours, which had a negative impact on our incremental margins. Future acquisitions may have a similar effect.

We may incur additional debt or issue additional equity to assist in the funding of these potential transactions, which may increase our leverage and/or dilute the interest of Holdings’ stockholders. Further, additional transactions could cause disruption of our ongoing business and divert management’s attention from the management of daily operations to the closing and integration of the acquired business. Acquisitions also involve other operational and financial risks such as:

We are growing rapidly and may not maintain or efficiently manage our growth.

We have rapidly grown our company through acquisitions of companies and assets as well as expansion of our own network and the acquisition of new customers through our own sales efforts. We also intend to continue to grow our company, including through acquisitions, some of which may be large. Customers can be reluctant to switch providers of bandwidth services because it can involve substantial expense and technical difficulty. That can make it harder for us to acquire new customers through our own sales efforts. Our expansion may place strains on our management and our operational and financial infrastructure. Our ability to manage our growth will be particularly dependent upon our ability to:

Service level agreements in our customer agreements could subject us to liability or the loss of revenue.

Our contracts with customers typically contain service guarantees (including network availability) and service delivery date targets, which could enable customers to claim credits and, under certain conditions, terminate their agreements. Our inability to meet our service level guarantees could adversely affect our revenue. In Fiscal 2015, lost revenue from failure to meet service level guarantees was approximately $0.9 million. While we typically have carve-outs for force majeure events, many events, such as fiber cuts, equipment failure and third-party vendors being unable to meet their underlying commitments with us, could impact our ability to meet our service level agreements.

Any failure of our physical infrastructure or services could lead to significant costs and disruptions.

Our business depends on providing customers with highly reliable service. The services we provide are subject to failure resulting from numerous factors, including:

Problems within our network or our datacenters, whether within our control or the control of our landlords or other third-party providers, could result in service interruptions or equipment damage. As current and future customers increase their power usage in our facilities over time, the remaining available power for future customers could limit our ability to grow our business and increase occupancy rates or network density within our existing facilities. Accordingly, we may not be able to efficiently upgrade or change these systems to meet new demands without incurring significant costs that we may not be able to pass on to our customers. In the past, we have experienced disruptions in our network attributed to equipment failure and power outages. Although such disruptions have been remedied and the network has been stabilized, there can be no assurance that similar disruptions will not occur in the future. Given the service level agreement obligations we typically have in our customer contracts, such disruptions could result in customer credits; however, we cannot assume that our customers will accept these credits as compensation in the future, and we may face additional liability or loss of customers.

We use franchises, licenses, permits, rights-of-way, conduit leases, fiber agreements, and property leases, which could be canceled or not renewed.

We must maintain rights-of-way, franchises, and other permits from railroads, utilities, state highway authorities, local governments, transit authorities, and others to operate our owned fiber network. We cannot be certain that we will be successful in maintaining these rights-of-way agreements or obtaining future agreements on acceptable terms. Some of these agreements are short-term or revocable at will, and we cannot assure you that we will continue to have access to existing rights-of-way after they have expired or terminated. If a material portion of these agreements are terminated or are not renewed, we might be forced to abandon our networks. In order to operate our networks, we must also maintain fiber leases and IRU agreements that we have with public and private entities. There is no assurance that we will be able to renew those fiber routes on favorable terms, or at all. If we are unable to renew those fiber routes on favorable terms, we may face increased costs or reduced revenues.

In order to expand our network to new locations, we often need to obtain additional rights-of-way, franchises, and other permits. Our failure to obtain these rights in a prompt and cost-effective manner may prevent us from expanding our network, which may be necessary to meet our contractual obligations to our customers and could expose us to liabilities.

If we lose or are unable to renew key real property leases where we have located our POPs, it could adversely affect our services and increase our costs, as we would be required to restructure our network and move our POPs.

We are required to maintain, repair, upgrade, and replace our network and our facilities, the cost of which could materially impact our results and our failure to do so could irreparably harm our business.

Our business requires that we maintain, repair, upgrade, and periodically replace our facilities and networks. This requires management time and capital expenditures. In the event that we fail to maintain, repair, upgrade, or replace essential portions of our network or facilities, it could lead to a material degradation in the level of service that we provide to our customers. Our networks can be damaged in a number of ways, including by other parties engaged in construction close to our network facilities. In the event of such damage, we will be required to incur expenses to repair the network. We could be subject to significant network repair and replacement expenses in the event a terrorist attack or a natural disaster damages our network. Further, the operation of our network requires the coordination and integration of sophisticated and highly specialized hardware and software. Our failure to maintain or properly operate this can lead to degradations or interruptions in customer service. Our

failure to provide proper customer service could result in claims from our customers, early termination of contracts, and damage our reputation.

Our debt level could negatively impact our financial condition, results of operations, cash flows, and business prospects and could prevent us from fulfilling our obligations under our outstanding indebtedness. In the future, we may incur substantially more indebtedness, which could further increase the risks associated with our leverage.

As of June 30, 2015, our total debt (including capital lease obligations and before any unamortized discounts, premiums or debt issuance costs) was $3,785.1 million, primarily consisting of our $1,430.0 million of 2023 Outstanding Notes, $350.0 million of 2025 Outstanding Notes, and $325.6 million of 10.125% senior unsecured notes due 2020 (the “2020 Unsecured Notes” collectively with the 2023 Outstanding Notes and the 2025 Outstanding Notes, the “Existing Notes”), $1,646.8 million senior secured term loan facility (the “Term Loan Facility”) and $32.7 million in capital lease obligations. In addition, we have a $450.0 million senior secured revolving credit facility (the “Revolver,” and collectively with the Term Loan Facility, the “Credit Facilities”), of which $440.8 million was available at June 30, 2015, subject to certain conditions. Subject to the limitations set forth in the indentures governing the Existing Notes and the agreement governing the Credit Facilities (the “Credit Agreement”), we may incur additional indebtedness (including additional first lien obligations) in the future. If new indebtedness is added to our current levels of indebtedness, the related risks that we now face in light of our current debt level, including our possible inability to service our debt, could intensify. Our level of debt could have important consequences, including the following:

Cash payments for interest, net of capitalized interest, which are reflected in our cash flows from operating activities, during the year ended June 30, 2015 was $191.2 million, and represented 32% of our cash flows from operating activities. Excluding our aggregate redemptions of $924.4 million of notes in December 2014 and March 2015 and Term Loan Facility repayment of $344.5 million in May 2015, we also made cash payments related to principal payments on our debt obligations (including capital leases) during the year ended June 30, 2015 of $23.1 million, which are reflected in our cash flows from financing activities, and represented 4% of our cash flows from operating activities during the period.

We may not be able to generate enough cash flow to meet our debt obligations.

Our future cash flow may be insufficient to meet our debt obligations and commitments. Any insufficiency could negatively impact our business. A range of economic, competitive, business, regulatory, and industry factors will affect our future financial performance, and, as a result, our ability to generate cash flow from

operations and to pay our debt. Many of these factors, such as economic and financial conditions in our industry and the U.S. or the global economy, or competitive initiatives of our competitors, are beyond our control.

If we do not generate enough cash flow from operations to satisfy our debt obligations, we may have to undertake alternative financing plans, such as:

We cannot assure you that we would be able to implement alternative financing plans, if necessary, on commercially reasonable terms, or at all, or that implementing any such alternative financing plans would allow us to meet our debt obligations.

If we are unable to meet our debt service obligations, it would be in default under the terms of the Indentures and the Credit Agreement, permitting acceleration of the amounts due on the Notes and under the Credit Agreement and eliminating our ability to draw on the Revolver. If the amounts outstanding under the Credit Facilities, the Notes, or other future indebtedness were to be accelerated, we could be forced to file for bankruptcy.

Our debt agreements contain restrictions on our ability to operate our business and to pursue our business strategies, and our failure to comply with these covenants could result in an acceleration of our indebtedness.

The Indentures and the Credit Facilities each contain, and agreements governing future debt issuances may contain, covenants that restrict our ability to, among other things:

As a result of these covenants, we are limited in the manner in which we may conduct our business, and as a result we may be unable to engage in favorable business activities or finance future operations or capital needs. The ability to comply with some of the covenants and restrictions contained in the Credit Agreement and the Indentures may be affected by events beyond our control. If market or other economic conditions deteriorate, our ability to comply with these covenants may be impaired. A failure to comply with the covenants, ratios, or tests in the Credit Agreement, the Indentures, or any future indebtedness could result in an event of default under the Credit Facilities, the Indentures or our future indebtedness, which if not cured could have a material adverse effect on our business, financial condition, and results of operations.

In addition, the Credit Facilities require us to comply with specified financial ratios, including ratios regarding total leverage and secured leverage. Our ability to comply with these ratios may be affected by events beyond our control. These restrictions limit our ability to plan for or react to market conditions, meet capital needs, or otherwise constrain our activities or business plans. They also may adversely affect our ability to finance our operations, enter into acquisitions, or engage in other business activities that would be in our interest.

A breach of any of the covenants contained in the Credit Agreement, in any future credit agreement or the Indentures or our inability to comply with the financial ratios could result in an event of default, which would allow the lenders to declare all borrowings outstanding to be due and payable or to terminate the ability to borrow under the Revolver. If the amounts outstanding under the Credit Facilities, the Notes or other future indebtedness were to be accelerated, we cannot assure that our assets would be sufficient to repay in full the money owed, including the Notes. In such a situation, we could be forced to file for bankruptcy.

Our future tax liabilities are not predictable or controllable. If we become subject to increased levels of taxation, our financial condition and operations could be negatively impacted.

We provide telecommunication and other services in multiple jurisdictions across the United States and Europe and are, therefore, subject to multiple sets of complex and varying tax laws and rules. We cannot predict the amount of future tax liabilities to which we may become subject. Any increase in the amount of taxation incurred as a result of our operations or due to legislative or regulatory changes would be adverse to us. In addition, we may become subject to income tax audits by many tax jurisdictions throughout the world. It is possible that certain tax positions taken by us could result in tax liabilities for us. While we believe that our current provisions for taxes are reasonable and appropriate, we cannot assure you that these items will be settled for the amounts accrued or that we will not identify additional exposures in the future.

We cannot assure you whether, when or in what amounts we will be able to use our net operating losses, or when they will be depleted.

At June 30, 2015, we had approximately $1,115.0 million of federal net operating losses (“NOLs”), which relate primarily to prior acquisitions. Under certain circumstances, these NOLs can be used to offset our future federal and certain taxable income. If we experience an “ownership change,” as defined in Section 382 of the Internal Revenue Code and related Treasury regulations at a time when our market capitalization is below a certain level, our ability to use the NOLs could be substantially limited. This limit could impact the timing of the usage of the NOLs, thus accelerating cash tax payments or causing NOLs to expire prior to their use, which could affect the ultimate realization of the NOLs.

Furthermore, transactions that we enter into, as well as transactions by existing or future 5% stockholders that we do not participate in, could cause us to incur an “ownership change,” which could prevent us from fully utilizing our NOLs to reduce our federal income taxes. These limitations could cause us not to pursue otherwise favorable acquisitions and other transactions involving our capital stock, or could reduce the net benefits to be realized from any such transactions. Despite this, we expect to use substantially all of these NOLs and certain other deferred tax attributes as an offset to our federal future taxable income, although the timing of that use will depend upon our future earnings and future tax circumstances. If and when our NOLs are fully utilized, we expect that the amount of our cash flow dedicated to the payment of federal taxes will increase substantially.

We may be subject to interest rate risk and increasing interest rates may increase our interest expense.

Borrowings under each of the Credit Facilities bear, and our future indebtedness may bear, interest at variable rates and expose us to interest rate risk. If interest rates increase, our debt service obligations on the variable rate indebtedness would increase even though the amount borrowed remained the same, and our net income and cash available for servicing our indebtedness would decrease.

The international operations of our business expose us to risks that could materially and adversely affect the business.

We have operations and investments outside of the United States, as well as rights to undersea cable capacity extending to other countries, that expose us to risks inherent in international operations. These include:

We may as part of our expansion strategy increase our exposure to international investments and operations.

Our international operations are subject to the laws and regulations of the U.S. and many foreign countries, including the U.S. Foreign Corrupt Practices Act and the U.K. Bribery Act.

We are subject to a variety of laws regarding our international operations, including the U.S. Foreign Corrupt Practices Act and the U.K. Bribery Act of 2010, and regulations issued by U.S. Customs and Border Protection, the U.S. Bureau of Industry and Security, the U.S. Treasury Department’s Office of Foreign Assets Control (“OFAC”) and various foreign governmental agencies. We cannot predict the nature, scope or effect of future regulatory requirements to which our international operations might be subject or the manner in which existing laws might be administered or interpreted. Actual or alleged violations of these laws could lead to enforcement actions and financial penalties that could result in substantial costs.

The U.S. Foreign Corrupt Practices Act, the U.K. Bribery Act and similar anti-bribery laws in other jurisdictions generally prohibit companies and their intermediaries from making improper payments for the purpose of obtaining or retaining business. Recent years have seen a substantial increase in anti-bribery law enforcement activity with more frequent and aggressive investigations and enforcement proceedings by both the Department of Justice and the U.S. Securities and Exchange Commission, increased enforcement activity by non-U.S. regulators and increases in criminal and civil proceedings brought against companies and individuals. We have created and implemented a program for compliance with anti-bribery laws. Because our anti-bribery internal control policies and procedures have been recently implemented, we may have increased exposure to reckless or criminal acts committed by our employees or third-party intermediaries. Violations of these anti-bribery laws may result in criminal or civil sanctions, which could have a material adverse effect on our business, financial condition, and results of operations.

We conduct a portion of our business using the British Pound Sterling and the Euro. Appreciation of the U.S. Dollar adversely affects our consolidated revenue. For example, the U.S. Dollar has appreciated significantly against the Euro in recent periods. Since we tend to incur costs in the same currency in which those

operations realize revenue, the effect on operating income and operating cash flow is largely mitigated. However, if the U.S. Dollar continues to appreciate significantly, future revenues, operating income and operating cash flows could be materially affected.

We may be vulnerable to security breaches that could disrupt our operations and adversely affect our business and operations.

Despite security measures and business continuity plans, our information technology networks and infrastructure may be vulnerable to damage, disruptions, or shutdowns due to unauthorized access, computer viruses, cyber-attacks, distributed denial of service, and other security breaches. An attack on or security breach of our network could result in interruption or cessation of services, our inability to meet our service level commitments, and potentially compromise customer data transmitted over our network. We cannot guarantee that our security measures will not be circumvented, resulting in network failures or interruptions that could impact our network availability and have a material adverse effect on our business, financial condition, and operational results. We may be required to expend significant resources to protect against such threats. If an actual or perceived breach of our security occurs, the market perception of the effectiveness of our security measures could be harmed, and we could lose customers. Any such events could result in legal claims or penalties, disruption in operations, misappropriation of sensitive data, damage to our reputation, and/or costly response measures, which could adversely affect our business.

We could face increased competition from companies in the telecommunications and media industries that currently do not focus on bandwidth infrastructure.

Many of our competitors in the bandwidth infrastructure space are other focused bandwidth infrastructure providers that operate on a regional or local basis. In some cases we also compete with communications service providers who also own certain infrastructure assets and make them available to customers as an infrastructure service. These communication service providers include ILECs, such as AT&T and Verizon, and cable television companies, such as Comcast.

Some of these competitors have greater financial, managerial, sales and marketing, and research and development resources than we do and are able to promote their brands with significantly larger budgets. Most of them are also our customers. If ILECs and cable television companies focus on providing bandwidth infrastructure, it could have a material adverse effect on us. A few of these competitors also have significant fiber assets that they principally employ in the provision of their communications services. If any of these competitors with greater resources and/or significant fiber assets chose to focus those resources on bandwidth infrastructure, our ability to compete in the bandwidth infrastructure industry could be negatively impacted. To the extent that communication service providers, cable television companies, and other media companies choose to distribute their content over their own networks that could reduce demand for our services. Additionally, significant new entrants into the bandwidth services industry would increase supply, which could cause prices for our services to decline.

Consolidation among companies in the telecommunications and cable television industries could further strengthen our competitors and adversely impact our business.

The telecommunications and cable television industries are intensely competitive and continue to undergo significant consolidation. There are many reasons for consolidation in these industries, including the desire for communications and cable television companies to acquire network assets in regions where they currently have no or insufficient amounts of owned network infrastructure. The consolidation within the industry may cause customers to disconnect services to move them to their own networks, or consolidate buying with other bandwidth infrastructure providers. Additionally, consolidation in the industry could further strengthen our

competitors, give them greater financial resources and geographic reach, and allow them to put additional pressure on prices for bandwidth infrastructure services.

Certain of our services are subject to regulation that could change or otherwise impact us in an adverse manner.

Communications services are subject to domestic and international regulation at the federal, state, and local levels. These regulations affect our business and our existing and potential competitors. Our electronic communications services and electronic communications networks in Europe and elsewhere are subject to regulatory oversight by national communications regulators, such as the United Kingdom’s Office of Communications (“Ofcom”) and France’s Autorité de Régulation des Communications Electroniques et des Postes (“ARCEP”). In addition, in the United States, both the Federal Communications Commission (“FCC”) and the state public utility commissions or similar regulatory authorities (the “State PUCs”) typically require us to file periodic reports, pay various regulatory fees and assessments, and to comply with their regulations. Such compliance can be costly and burdensome and may affect the way we conduct our business. Delays in receiving required regulatory approvals (including approvals relating to acquisitions or financing activities or for interconnection agreements with other carriers), the enactment of new and adverse international or domestic legislation or regulations (including those pertaining to broadband initiatives and net-neutrality), or the denial, modification or termination by a regulator of any approval or authorization, could have a material adverse effect on our business. Further, the current regulatory landscape is subject to change through judicial review of current legislation and rulemaking by the FCC, Ofcom, ARCEP, and other domestic, foreign, and international rulemaking bodies. These bodies regularly consider changes to their regulatory framework and fee obligations. Changes in current regulation may make it more difficult to obtain the approvals necessary to operate our business, significantly increase the regulatory fees to which we are subject, or have other adverse effects on our future operations in the United States and Europe.

We may be liable for the material that content providers distribute over our network.

Although we believe our liability for third party information stored on or transmitted through our networks is limited, the liability of private network operators is limited both by changing technology and evolving legal principles. As a private network provider, we could be exposed to legal claims relating to third party content stored or transmitted on our networks. Such claims could involve, among others, allegations of defamation, invasion of privacy, copyright infringement, or aiding and abetting restricted activities such as online gambling or pornography. If we decide to implement additional measures to reduce our exposure to these risks or if we are required to defend ourselves against these kinds of claims, our operating results and financial condition could be negatively affected.

Unfavorable general global economic conditions could negatively impact our operating results and financial condition.

Unfavorable general global economic conditions could negatively affect our business. Although it is difficult to predict the impact of general economic conditions on our business, these conditions could adversely affect the affordability of, and customer demand for, our services, and could cause customers to delay or forgo purchases of our services. One or more of these circumstances could cause our revenue to decline. Also, our customers may not be able to obtain adequate access to credit, which could affect their ability to purchase our services or make timely payments to us. The current economic conditions, including federal fiscal and monetary policy actions, may lead to inflationary conditions in our cost base, particularly in our lease and personnel related expenses. This could harm our margins and profitability if we are unable to increase prices or reduce costs sufficiently to offset the effects of inflation in our cost base. For these reasons, among others, if challenging economic conditions persist or worsen, our operating results and financial condition could be adversely affected.

Disruptions in the financial markets could affect our ability to obtain debt or equity financing or to refinance our existing indebtedness on reasonable terms or at all.

Disruptions in the financial markets could impact our ability to obtain debt or equity financing, or lines of credit, in the future as well as impact our ability to refinance our existing indebtedness on reasonable terms or at all, which could affect our strategic operations and our financial performance and force modifications to our operations.

Changes in our traffic patterns or industry practice could result in increasing peering costs for our IP network.

Peering agreements with other ISPs have allowed us to access the Internet and exchange traffic with these providers. In most cases, we peer with these ISPs on a payment-free basis, referred to as settlement-free peering. We plan to continue to leverage this settlement-free peering. If other providers change the terms upon which they allow settlement-free peering or if changes in Internet traffic patterns, including the ratio of inbound to outbound traffic, cause us to fall below the criteria that these providers use in allowing settlement-free peering, the costs of operating our Internet backbone will likely increase. Any increases in costs could have an adverse effect on our margins and our ability to compete in the IP market.

The ongoing threat of terrorist activity and other acts of war or hostility have had, and may continue to have, an adverse effect on business, financial and general economic conditions. Effects from these events and any future terrorist activity, including cyber terrorism, may, in turn, increase our costs due to the need to provide enhanced security, which would adversely affect our business and results of operations. Terrorist activity could damage or destroy our Internet infrastructure and may adversely affect our ability to attract and retain customers, raise capital, and operate and maintain our network access points. We are particularly vulnerable to acts of terrorism because of our large datacenter presence in New York. We are also susceptible to other catastrophic events such as major natural disasters, extreme weather, fires, or similar events that could affect our headquarters, other offices, our network, infrastructure, or equipment, all of which could adversely affect our business.

The Notes will be structurally subordinated to all liabilities of subsidiaries that are not Guarantors.

Certain of our current and future subsidiaries (foreign subsidiaries that do not guarantee any of our other indebtedness and unrestricted subsidiaries) will not guarantee the Notes. See “Description of 2023 Notes—Note Guarantees” and “Description of 2025 Notes—Note Guarantees.” In the event of a bankruptcy, liquidation or reorganization of any future non-guarantor subsidiary, including any of our future foreign subsidiaries that do not guarantee any of our other indebtedness, holders of their indebtedness and their trade creditors will generally be entitled to payment of their claims from the assets of those entities before any assets are made available for distribution to us. As a result, the Notes will effectively be subordinated to the prior payment of all of the liabilities of all future non-guarantor subsidiaries. Non-guarantor subsidiaries are separate and distinct legal entities and have no obligation, contingent or otherwise, to pay amounts due pursuant to the Notes or to make any funds available therefor, whether by dividends, loans, distributions or other payments.

We will need to repay or refinance any indebtedness under our Revolver and Term Loan Facility prior to the maturity of the Notes.

Our Revolver and Term Loan Facility will mature prior to the maturity of the Notes. If we are unable to repay, extend, or refinance either of the Credit Facilities prior to maturity, it would have a material adverse effect on the value of the Notes. In addition, any debt that we incur to refinance debt under either of the Credit Facilities could also mature prior to the Notes, and could therefore create the same financing risk.

A financial failure by us, any of our subsidiaries or any other entity in which we have an interest may result in the assets of any or all of those entities becoming subject to the claims of all creditors of those entities.

A financial failure by us, any of our subsidiaries or any other entity in which we have an interest could affect payment of the Notes if a bankruptcy court were to “substantively consolidate” us and our subsidiaries, including entities in which we have an interest but whose financial statements are not consolidated with our financial statements. If a bankruptcy court substantively consolidated us and our subsidiaries, including entities in which we have an interest but whose financial statements are not consolidated with ours, the assets of each entity would be subject to the claims of creditors of all entities. This would expose holders of the Notes not only to the usual impairments arising from bankruptcy, but also to potential dilution of the amount ultimately recoverable because of the larger creditor base. The Indenture does not limit the ability of entities whose financial statements are not consolidated with us to incur debt, which could increase this risk. Furthermore, forced restructuring of the Notes could occur through the “cram-down” provision of the bankruptcy code. Under this provision, the Notes could be restructured over your objections as to their general terms, primarily interest rate and maturity.

Upon a change of control as defined in the Indenture, we will be required to make an offer to repurchase all outstanding Notes at 101% of their principal amount plus accrued and unpaid interest, unless we have previously given notice of our intention to exercise our right to redeem the notes or unless such obligation is suspended. See “Description of the 2023 Notes—Offers to Purchase; Open Market and Other Purchases—Repurchase at the Option of Holders—Change of Control” and “Description of the 2025 Notes—Offers to Purchase; Open Market and Other Purchases—Repurchase at the Option of Holders—Change of Control.” We may not have sufficient financial resources to purchase all of the Notes that are tendered upon a change of control offer or, if then permitted under the Indenture governing the Notes, to redeem the notes. A failure to make the applicable change of control offer or to pay the applicable change of control purchase price when due would result in a default under each of the Indenture. The occurrence of a change of control would also constitute an event of default under the Indenture, each of the Existing Indentures and our Credit Facilities and may constitute an event of default under the terms of our other indebtedness. In the event any purchase or redemption is prohibited, we may seek to obtain waivers from the required lenders under our Credit Facilities or holders of other indebtedness to permit the required repurchase or redemption, but the required holders of such indebtedness have no obligation to grant, and may refuse to grant such a waiver.

The ability of holders of Notes to require us to repurchase Notes as a result of a disposition of “substantially all” of our assets or a change in the composition of our board of directors is uncertain.

The definition of change of control in the Indenture includes a phrase relating to the direct or indirect sale, transfer, conveyance or other disposition of “all or substantially all” of our assets and the assets of our subsidiaries, taken as a whole. Although there is a limited body of case law interpreting the phrase “substantially all,” there is no precise established definition of the phrase. Accordingly, the ability of a holder of Notes to require us to repurchase such Notes as a result of a sale, transfer, conveyance or other disposition of less than all of our and our restricted subsidiaries’ assets taken as a whole to another person or group is uncertain. In addition, a recent Delaware Chancery Court decision raised questions about the enforceability of provisions that are similar to those in the Indentures, related to the triggering of a change of control as a result of a change in the composition of a board of directors. Accordingly, the ability of a holder of Notes to require us to repurchase Notes as a result of a change in the composition of the directors on our board is uncertain.

Federal and state statutes allow courts, under specific circumstances, to cancel the Notes or the related guarantees and require noteholders to return payments received from us or the Guarantors.

Our creditors or the creditors of the Guarantors of the Notes could challenge the issuance of the Notes and the related guarantees as fraudulent conveyances or on other grounds. Under federal bankruptcy law and

comparable provisions of state fraudulent transfer laws, the delivery of the Notes or the guarantees could be found to be a fraudulent transfer and declared void if a court determined that we or the relevant guarantor, at the time that we or the relevant guarantor incurred the indebtedness evidenced by the note or its guarantee, as applicable, (1) delivered the note or guarantee, as applicable, with the intent to hinder, delay or defraud existing or future creditors; or (2) received less than reasonably equivalent value or did not receive fair consideration for the delivery of the note or guarantee, as applicable, and any of the following three conditions apply:

In addition, any payment by us or that guarantor pursuant to the Notes or its guarantee, as applicable, could be voided and required to be returned to us or the guarantor, or to a fund for the benefit of the creditors of us or the guarantor, as applicable. In any such case, the right of noteholders to receive payments in respect of the Notes from us or any such guarantor, as applicable, would be effectively subordinated to all indebtedness and other liabilities of ours or that guarantor.

The Indenture contains a “savings clause,” which limits the liability of each guarantor that is a subsidiary of ours on its guarantee to the maximum amount that such guarantor can incur without risk that its guarantee will be subject to avoidance as a fraudulent transfer. We cannot assure you that this limitation will protect such guarantees from fraudulent transfer challenges or, if it does, that the remaining amount due and collectible under the guarantees would suffice, if necessary, to pay the Notes in full when due. Furthermore, in a recent case, Official Committee of Unsecured Creditors of TOUSA, Inc. v. Citicorp North America, Inc., the U.S. Bankruptcy Court in the Southern District of Florida held that a savings clause similar to the savings clause used in the indenture was unenforceable. As a result, the subsidiary guarantees were found to be fraudulent conveyances. The United States Court of Appeals for the Eleventh Circuit recently affirmed the liability findings of the Bankruptcy Court without ruling directly on the enforceability of savings clauses generally. If the TOUSA decision is followed by other courts, the risk that the guarantees would be deemed fraudulent conveyances would be significantly increased.

If a court declares the Notes or guarantees to be void, or if the Notes or guarantees must be limited or voided in accordance with their terms, any claim a noteholder may make against us for amounts payable on the Notes could, with respect to amounts claimed against us or the Guarantors, be subordinated to our indebtedness and the indebtedness of the Guarantors, including trade payables. The measures of insolvency for purposes of these fraudulent transfer laws vary depending upon the law applied in any proceeding to determine whether a fraudulent transfer has occurred. Generally, however, we or a guarantor would be considered insolvent if:

On the basis of historical financial information, recent operating history and other factors, we believe that we and each guarantor, after giving effect to the issuance of the Notes and its guarantee of the Notes, respectively, will not be insolvent, will not have unreasonably small capital for the business in which we or it is engaged and will not have incurred debts beyond our or its ability to pay such debts as they mature. We cannot assure you, however, as to what standard a court would apply in making these determinations or that a court would agree with our conclusions in this regard.

We may be subject to interest rate risk and increasing interest rates may increase our interest expense.

The Indenture and the agreements governing our existing indebtedness each contain, and agreements governing future debt issuances may contain, covenants that restrict our ability to, among other things:

As a result of these covenants, we are limited in the manner in which we may conduct our business, and as a result we may be unable to engage in favorable business activities or finance future operations or capital needs. The ability to comply with some of the covenants and restrictions contained in the Indenture and the agreements governing our existing indebtedness may be affected by events beyond our control. If market or other economic conditions deteriorate, our ability to comply with these covenants may be impaired. A failure to comply with the covenants, ratios, or tests in the Indenture and the agreements governing our existing indebtedness or any future indebtedness could result in an event of default under the Indenture and the agreements governing our existing indebtedness or our future indebtedness, which, if not cured or waived, could have a material adverse effect on our business, financial condition, and results of operations.

In addition, the Credit Facilities require us to comply with specified financial ratios. Our ability to comply with these ratios may be affected by events beyond our control. These restrictions limit our ability to plan for or react to market conditions, meet capital needs, or otherwise constrain our activities or business plans. They also may adversely affect our ability to finance our operations, enter into acquisitions, or engage in other business activities that would be in our interest.

A breach of any of the covenants contained in the Indenture and the agreements governing our existing or future indebtedness or our inability to comply with the financial ratios could result in an event of default, which would allow the lenders to declare all borrowings outstanding to be due and payable or to terminate the ability to borrow under the Revolver. If the amounts outstanding under the Credit Facilities, the Notes or other future indebtedness were to be accelerated, we cannot assure that our assets would be sufficient to repay in full the money owed, including the Notes. In such a situation, we could be forced to file for bankruptcy.

The Notes are new issues of securities, and there is no existing trading market for the Notes. Although the initial purchasers have informed us that they intend to make a market in the Notes, they have no obligation to do

so and may discontinue making a market at any time without notice. Accordingly, we cannot assure you that a liquid market will develop for the Notes, that you will be able to sell your Notes at a particular time or that the prices that you receive when you sell the Notes will be favorable.

We do not intend to apply for listing or quotation of the Notes on any securities exchange or stock market. The liquidity of any market for the Notes will depend on a number of factors, including:

Historically, the market for non-investment grade debt has been subject to disruptions that have caused substantial volatility in the prices of these securities. We cannot assure you that the market for the Notes will be free from similar disruptions. Any disruptions could have an adverse effect on noteholders. In addition, subsequent to their initial issuance, the Notes may trade at a discount from their initial offering price depending upon prevailing interest rates, the market for similar Notes, our performance, or other factors.

The Company is dependent upon dividends from its subsidiaries to meet its debt service obligations.

The Company is a holding company and conducts all of its operations through its subsidiaries. The Company’s ability to meet its debt service obligations will be dependent on receipt of dividends from its direct and indirect subsidiaries. Subject to the restrictions contained in the Indenture and the agreements governing our existing indebtedness, future borrowings by our subsidiaries may contain restrictions or prohibitions on the payment of dividends by the Company’s subsidiaries to the Company. In addition, federal and state corporate law and federal and state regulatory requirements may limit the ability of the Company’s subsidiaries to pay dividends to it. We cannot assure you that the agreements governing the current and future indebtedness of the Company’s subsidiaries, applicable laws, or state regulation will permit the Company’s subsidiaries to provide it with sufficient dividends, distributions or loans to fund payment of the Notes, or to fund our other liquidity needs.

The Notes will be joint and several obligations of a Delaware limited liability company and a Delaware corporation, the latter of which has no independent operations or subsidiaries and generates no cash flow to service the Notes.

Zayo Capital is, as of the date of this prospectus, a finance company with no independent operations and no material assets. As a result of the foregoing, Zayo Capital has no cash flows and will provide no credit support for the Notes.

Despite our current leverage, we may still be able to incur substantially more debt. This could further exacerbate the risks that we and our subsidiaries face.

We may be able to incur additional debt in the future. The terms of the Indenture and the agreements governing our existing indebtedness allow us to incur substantial amounts of additional debt, subject to certain limitations. If additional debt is added to our current debt levels, the related risks we could face would be magnified.

Servicing our debt requires a significant amount of cash, and we may not have sufficient cash flow from our business to pay our substantial debt.

Our ability to make scheduled principal and interest payments on our indebtedness, including the Notes, and our ability to refinance that indebtedness, will depend upon our future operating performance, which is subject to general economic and competitive conditions and to financial, business and other factors, many of which we cannot control. If we do not have sufficient funds on hand to pay our debt, we may be required to seek a waiver or amendment from our lenders, refinance our indebtedness, sell assets, or sell additional shares of securities. Our ability to refinance our indebtedness will depend on the capital markets and our financial condition at the time. We may not be able obtain such financing or complete such transactions on terms acceptable to us, or at all. In addition, we may not be able to consummate an asset sale to raise capital or sell assets at prices that we believe are fair, and proceeds that we do receive may not be adequate to meet any debt service obligations then due. The Indenture and the agreements governing our existing indebtedness restrict our ability to use the proceeds from asset sales. Our failure to generate sufficient funds to pay our debts or to undertake any of these actions successfully could result in a default on our debt obligations, which would materially adversely affect our business, results of operations and financial condition and our ability to satisfy our obligation under the Notes.

There are significant restrictions on your ability to transfer or resell the Notes.

The Notes are being offered and sold pursuant to an exemption from registration under the Securities Act and applicable state securities laws. Therefore, you may transfer or resell the Notes in the United States only in a transaction registered under or exempt from the registration requirements of the Securities Act and applicable state securities laws, and you may be required to bear the risk of your investment for an indefinite period of time. See “Notice to Investors.” Under the registration rights agreement, we have agreed to file with the SEC an exchange offer registration statement or, under some circumstances, a shelf registration statement with respect to the Notes and to use our reasonable best efforts to cause the registration statement to become effective. The SEC, however, has broad discretion to declare any registration statement effective and may delay, defer or suspend the effectiveness of any registration statement for a variety of reasons. If issued under an effective registration statement, the exchange Notes generally may be resold or otherwise transferred by each holder of the exchange notes with no need for further registration. However, the exchange notes will constitute a new issue of securities with no established trading market. An active trading market for the exchange notes may not develop, or, in the case of non-exchanging holders of the Notes, the trading market for the Notes following the exchange offer may not continue.

Any rating downgrade for the Notes may cause the price of the Notes to fall.

We have received credit ratings from certain rating services in connection with this offering of the Notes. In the event a rating service were to lower its rating on the Notes below the rating initially assigned to the Notes or otherwise announce its intention to put the Notes on credit watch, the price of the Notes could decline.

The following table sets forth our historical ratio of earnings to fixed charges for the periods indicated. For the purposes of computing the ratio of earnings to fixed charges, earnings consist of earnings/(loss) from continuing operations before income taxes, as adjusted to include fixed charges. Fixed charges consist of interest expense on all indebtedness, amortization of debt discount, and amortization of debt issuance costs and that portion of rental expense under operating leases that we believe to be a reasonable approximation of interest factor.

This exchange offer is being made pursuant to the registration rights agreements. The summary of the registration rights agreements contained herein does not purport to be complete and is qualified in its entirety by reference to each of the registration rights agreements. A copy of each of the registration rights agreements is filed as an exhibit to the registration statement of which this prospectus forms a part.

This prospectus and the accompanying letter of transmittal together constitute the exchange offer. Subject to the terms and conditions in this prospectus and the letter of transmittal, we will accept for exchange Outstanding Notes that are validly tendered at or prior to the expiration time and are not validly withdrawn as permitted below. The expiration time for the exchange offer is 5:00 p.m., New York City time, on November 18, 2015, or such later date and time to which we, in our sole discretion, extend the exchange offer.

In the event of a material change in the exchange offer, including the waiver of a material condition, we will extend the exchange offer period if necessary so that at least five business days remain in the exchange offer following notice of the material change. We will give written notice of any extension, non-acceptance, termination, or amendment as promptly as practicable by a public announcement. In the case of an extension, such public announcement shall be made no later than 9:00 a.m., New York City time, on the next business day after the previously scheduled expiration time and shall include disclosure of the approximate number of Outstanding Notes tendered to date.

During an extension, all Outstanding Notes previously tendered will remain subject to the exchange offer and may be accepted for exchange by us, upon expiration of the exchange offer, unless validly withdrawn.

Each broker-dealer that receives Exchange Notes for its own account in exchange for Outstanding Notes, where such Outstanding Notes were acquired by such broker-dealer as a result of market-making activities or other trading activities, must acknowledge in the letter of transmittal that it will deliver a prospectus in connection with any resale of such Exchange Notes. See “Plan of Distribution.”

Only a record holder of Outstanding Notes may tender in the exchange offer. When the holder of Outstanding Notes tenders and we accept Outstanding Notes for exchange, a binding agreement between us and the tendering holder is created, subject to the terms and conditions in this prospectus and the accompanying letter of transmittal. Except as set forth below, a holder of Outstanding Notes who desires to tender Outstanding Notes for exchange must, at or prior to the expiration time:

The method of delivery of the Outstanding Notes, the letter of transmittal or agent’s message, and all other required documents to the exchange agent is at the election and sole risk of the holder. If such delivery is by mail, we recommend registered mail, properly insured, with return receipt requested. In all cases, you should allow sufficient time to assure timely delivery. No letters of transmittal or Outstanding Notes should be sent directly to us.

Signatures on a letter of transmittal must be guaranteed unless the Outstanding Notes surrendered for exchange are tendered:

If signatures on a letter of transmittal or notice of withdrawal are required to be guaranteed, the guarantor must be an eligible institution. If Outstanding Notes are registered in the name of a person other than the person who signed the letter of transmittal, the Outstanding Notes tendered for exchange must be endorsed by, or accompanied by a written instrument or instruments of transfer or exchange, in satisfactory form as determined by us in our sole discretion, duly executed by the registered holder with the registered holder’s signature guaranteed by an eligible institution.

We, in our reasonable judgment, will make a final and binding determination of all questions as to the validity, form, eligibility (including time of receipt), and acceptance of Outstanding Notes tendered for exchange and all other required documents based upon whether the Outstanding Notes and all such other documents have been properly tendered in accordance with the procedures set forth in this prospectus. We reserve the absolute right to:

Our interpretation of the terms and conditions of the exchange offer as to any particular Outstanding Note, either before or after the expiration time (including the letter of transmittal and the instructions thereto), will be final and binding on all parties. To the extent we waive any conditions to the exchange offer, we will waive such conditions as to all Outstanding Notes. Holders must cure any defects and irregularities in connection with tenders of Outstanding Notes for exchange within such reasonable period of time as we will determine, unless we waive such defects or irregularities. Neither we, the exchange agent, nor any other person will be under any duty to give notification of any defect or irregularity with respect to any tender of Outstanding Notes for exchange, nor will any of us incur any liability for failure to give such notification.

WE MAKE NO RECOMMENDATION TO THE HOLDERS OF THE OUTSTANDING NOTES AS TO WHETHER TO TENDER OR REFRAIN FROM TENDERING ALL OR ANY PORTION OF THEIR OUTSTANDING NOTES IN THE EXCHANGE OFFER. IN ADDITION, WE HAVE NOT AUTHORIZED ANYONE TO MAKE ANY SUCH RECOMMENDATION. HOLDERS OF THE OUTSTANDING NOTES MUST MAKE THEIR OWN DECISION AS TO WHETHER TO TENDER PURSUANT TO THE EXCHANGE OFFER, AND, IF SO, THE AGGREGATE AMOUNT OF OUTSTANDING NOTES TO TENDER, AFTER READING THIS PROSPECTUS AND THE LETTER OF TRANSMITTAL AND CONSULTING WITH THEIR ADVISERS, IF ANY, BASED ON THEIR FINANCIAL POSITIONS AND REQUIREMENTS.

Any financial institution that is a participant in DTC’s system must make book-entry delivery of Outstanding Notes by causing DTC to transfer the Outstanding Notes into the exchange agent’s account at DTC in accordance with DTC’s Automated Tender Offer Program, known as ATOP. Such participant should transmit its acceptance to DTC at or prior to the expiration time or comply with the guaranteed delivery procedures described below. DTC will verify such acceptance, execute a book-entry transfer of the tendered Outstanding Notes into the exchange agent’s account at DTC and then send to the exchange agent confirmation of such book-entry transfer. The confirmation of such book-entry transfer will include an agent’s message. The letter of transmittal or facsimile thereof or an agent’s message, with any required signature guarantees and any other required documents, must be transmitted to and received by the exchange agent at the address set forth below under “—The Exchange Agent” at or prior to the expiration time of the exchange offer, or the holder must comply with the guaranteed delivery procedures described below.

If a holder of Outstanding Notes desires to tender such notes and the holder’s notes are not immediately available, or time will not permit such holder’s Outstanding Notes or other required documents to reach the exchange agent at or prior to the expiration time, or the procedure for book-entry transfer cannot be completed on a timely basis, a tender may be effected if:

The notice of guaranteed delivery must be received at or prior to the expiration time.

You may withdraw tenders of your Outstanding Notes at any time at or prior to the expiration time.

For a withdrawal to be effective, a written notice of withdrawal, by facsimile or by mail, must be received by the exchange agent, at the address set forth below under “—The Exchange Agent,” at or prior to the expiration time. Any such notice of withdrawal must:

We will determine all questions as to the validity, form, and eligibility (including time of receipt) of such notices and our determination will be final and binding on all parties. Any tendered Outstanding Notes validly withdrawn will be deemed not to have been validly tendered for exchange for purposes of the exchange offer. Properly withdrawn Notes may be re-tendered by following one of the procedures described under “—How to Tender Outstanding Notes for Exchange” above at any time at or prior to the expiration time.

All of the conditions to the exchange offer must be satisfied or waived at or prior to the expiration of the exchange offer. Promptly following the expiration time we will accept for exchange all Outstanding Notes validly tendered and not validly withdrawn as of such date. We will promptly issue Exchange Notes for all validly tendered Outstanding Notes. For purposes of the exchange offer, we will be deemed to have accepted validly tendered Outstanding Notes for exchange when, as, and if we have given oral or written notice to the exchange agent, with written confirmation of any oral notice to be given promptly thereafter. See “—Conditions to the Exchange Offer” for a discussion of the conditions that must be satisfied before we accept any Outstanding Notes for exchange.

For each Outstanding Note accepted for exchange, the holder will receive an exchange note of the same series registered under the Securities Act having a principal amount equal to, and in the denomination of, that of the surrendered outstanding note. Accordingly, registered holders of Exchange Notes that are outstanding on the relevant record date for the first interest payment date following the consummation of the exchange offer will receive interest accruing from the most recent date through which interest has been paid on the Outstanding Notes, or if no interest has been paid, from the original issue date of the Outstanding Notes. Outstanding Notes that we accept for exchange will cease to accrue interest from and after the date of consummation of the exchange offer.

If we do not accept any tendered Outstanding Notes, or if a holder submits Outstanding Notes for a greater principal amount than the holder desires to exchange, we will promptly return such unaccepted or non-exchanged Outstanding Notes without cost to the tendering holder. In the case of Outstanding Notes tendered by book-entry transfer into the exchange agent’s account at DTC, such non-exchanged Outstanding Notes will be credited to an account maintained with DTC. We will return the Outstanding Notes or have them credited to DTC promptly after the withdrawal, rejection of tender or termination of the exchange offer, as applicable. The untendered portion of any untendered note tendered in part must be in denominations of $2,000 or integral multiples of $1,000 in excess thereof.

The exchange offer is not conditioned upon the tender of any minimum principal amount of Outstanding Notes. 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 issue Exchange Notes in exchange for, any Outstanding Notes and may terminate or amend the exchange offer, by oral (promptly confirmed in writing) or written notice to the exchange agent or by a timely press release, if at any time before the expiration of the exchange offer, any of the following conditions exist:

For accounting purposes, we will not recognize gain or loss upon the issuance of the Exchange Notes for Outstanding Notes. We are capitalizing costs incurred in connection with the issuance of the exchange notes and amortizing those costs over the life of the debt.

We will not make any payment to brokers, dealers, or others soliciting acceptance of the exchange offer except for reimbursement of mailing expenses. We will pay the cash expenses to be incurred in connection with the exchange offer, including:

Holders who tender their Outstanding Notes for exchange will not be obligated to pay any transfer taxes in connection with the exchange. If, however, Exchange Notes issued in the exchange offer are to be delivered to, or are to be issued in the name of, any person other than the holder of the Outstanding Notes tendered, or if a transfer tax is imposed for any reason other than the exchange of Outstanding Notes in connection with the exchange offer, then the holder must pay these transfer taxes, whether imposed on the registered holder or on any other person. If satisfactory evidence of payment of or exemption from these taxes is not submitted with the letter of transmittal, the amount of these transfer taxes will be billed directly to the tendering holder.

We have appointed The Bank of New York Mellon Trust Company, N.A. as our exchange agent for the exchange offer. All executed letters of transmittal should be directed to the exchange agent at the address set forth below. Questions and requests for assistance with respect to the procedures for the exchange offer, requests for additional copies of this prospectus or of the letter of transmittal and requests for notices of guaranteed delivery should also be directed to the exchange agent at the address below:

Delivery of the letter of transmittal to an address other than as set forth above or transmission of such letter of transmittal via facsimile other than as set forth above will not constitute a valid delivery.

Outstanding Notes that are not tendered or are tendered but not accepted will, following the consummation of the exchange offer, continue to accrue interest and be subject to the provisions in the Indentures and the legend contained on the Outstanding Notes regarding the transfer restrictions of the Outstanding Notes but will not retain any rights under the applicable registration rights agreements. In general, Outstanding Notes, unless registered under the Securities Act, may not be offered or sold except pursuant to an exemption from, or in a transaction not subject to, the Securities Act and applicable state securities laws. We do not currently anticipate that we will take any action to register under the Securities Act or under any state securities laws the Outstanding Notes that are not tendered in the exchange offer or that are tendered in the exchange offer but are not accepted for exchange.

Holders of the Exchange Notes of any series and any Outstanding Notes of such series that remain outstanding after consummation of the exchange offer will vote together as a single series for purposes of determining whether holders of the requisite percentage of the Notes have taken certain actions or exercised certain rights under the Indentures.

We have not requested, and do not intend to request, an interpretation by the staff of the SEC as to whether the Exchange Notes issued in the exchange offer may be offered for sale, resold, or otherwise transferred by any holder without compliance with the registration and prospectus delivery provisions of the Securities Act. However, based on interpretations of the staff of the SEC, as set forth in a series of no-action letters issued to third parties, we believe that the Exchange Notes may be offered for resale, resold, or otherwise transferred by holders of those Exchange Notes without compliance with the registration and prospectus delivery provisions of the Securities Act, provided that:

Each holder participating in the exchange offer will be required to furnish us with a written representation in the letter of transmittal that they meet each of these conditions and agree to these terms.

However, because the SEC has not considered the exchange offer for our Outstanding Notes in the context of a no-action letter, we cannot guarantee that the staff of the SEC would make similar determinations with respect to this exchange offer. If our belief is not accurate and you transfer an exchange note without delivering a prospectus meeting the requirements of the federal securities laws or without an exemption from these laws, you may incur liability under the federal securities laws. We do not and will not assume, or indemnify you against, this liability.

Any holder that is an affiliate of ours or that tenders Outstanding Notes in the exchange offer for the purpose of participating in a distribution:

The Exchange Notes issued in the exchange offer may not be offered or sold in any state unless they have been registered or qualified for sale in such state or an exemption from registration or qualification is available and complied with by the holders selling the Exchange Notes. We currently do not intend to register or qualify the sale of the Exchange Notes in any state where we would not otherwise be required to qualify.

Under the registration rights agreements we agreed, among other things, that if:

(1) we are not permitted to consummate the exchange offer because the exchange offer is not permitted by applicable law or any applicable interpretation of the staff of the SEC;

(2) the exchange offer is not consummated, for any reason, on or before (i) January 23, 2016 with respect to the 2023 Notes, or (ii) May 6, 2016 with respect to the 2025 Notes; or

(a) it is prohibited by law or SEC policy from participating in the exchange offer;

(b) it may not resell the Exchange Notes acquired by it in the exchange offer to the public without delivering a prospectus, and the prospectus contained in the exchange offer registration statement is not appropriate or available for such resales; or

then we will file with the SEC a shelf registration statement to cover resales of the Notes by the holders of the Notes who satisfy certain conditions relating to the provision of information in connection with the shelf registration statement.

If obligated to file the shelf registration statement, we will use our reasonable best efforts to cause the shelf registration statement to be declared effective by the SEC as promptly as possible after the obligation to file such shelf registration statement arises.

If the shelf registration statement is declared effective but thereafter ceases to be effective or usable in connection with resales of Outstanding Notes during the periods specified in the registration rights agreement (except with respect to permitted suspension periods as provided therein), then we will pay Additional Interest to each holder of affected Outstanding Notes on the terms provided in the registration rights agreement.

Holders of Notes will be required to deliver certain information to be used in connection with the shelf registration statement and to provide comments on the shelf registration statement within the time periods set forth in the registration rights agreements in order to have their Notes included in the shelf registration statement and benefit from the provisions regarding Additional Interest set forth above. By acquiring Outstanding Notes, a holder will be deemed to have agreed to indemnify us against certain losses arising out of information furnished by such holder in writing for inclusion in any shelf registration statement. Holders of Notes will also be required to suspend their use of the prospectus included in the shelf registration statement under certain circumstances upon receipt of written notice to that effect from us.

Although we intend, if required, to file the shelf registration statement, we cannot assure you that the shelf registration statement will be filed or, if filed, that it will become or remain effective.

The foregoing description is a summary of certain provisions of the registration rights agreements. It does not restate the registration rights agreements in their entirety. We urge you to read the registration rights agreements, which are exhibits to the registration statement of which this prospectus forms a part and can also be obtained from us. See “Where You Can Find More Information.”

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following management’s discussion and analysis of financial condition and results of operations contains forward-looking statements that involve risks and uncertainties. Please see “Forward-Looking Statements” and “Risk Factors” for a discussion of the uncertainties, risks and assumptions that may cause our actual results to differ materially from those currently anticipated. This discussion should be read in conjunction with the “Selected Historical Consolidated Financial Information” and our historical consolidated financial statements and related notes as of June 30, 2014 and 2015 and for the fiscal years ended June 30, 2013, 2014 and 2015 included in this prospectus.

The following discussion and analysis should be read together with our audited consolidated financial statements and the related notes appearing elsewhere in this prospectus.

Amounts presented in this “Management’s Discussion and Analysis of Financial Condition and Results of Operations” are rounded. As such, rounding differences could occur in period-over-period changes and percentages reported throughout this section.

We are a large and fast growing provider of bandwidth infrastructure in the United States and Europe. Our products and services enable mission-critical, high-bandwidth applications, such as cloud-based computing, video, mobile, social media, machine-to-machine connectivity, and other bandwidth-intensive applications. Key products include leased dark fiber, fiber to cellular towers and small cell sites, dedicated wavelength connections, Ethernet, IP connectivity, cloud services and other high-bandwidth offerings. We provide our services over a unique set of dense metro, regional, and long-haul fiber networks and through our interconnect-oriented datacenter facilities. Our fiber networks and datacenter facilities are critical components of the overall physical network architecture of the Internet and private networks. Our customer base includes some of the largest and most sophisticated consumers of bandwidth infrastructure services, such as wireless service providers; telecommunications service providers; financial services companies; social networking, media, and web content companies; education, research, and healthcare institutions; and governmental agencies. We typically provide our bandwidth infrastructure services for a fixed monthly recurring fee under contracts that vary between one and twenty years in length. As of June 30, 2015, we had $6.0 billion in revenue under contract with a weighted average remaining contract term of approximately 46 months. We operate our business with a unique focus on capital allocation and financial performance with the ultimate goal of maximizing equity value for Holdings’ stockholders. Our core values center on partnership, alignment, and transparency with our three primary constituent groups-employees, customers, and stockholders.

We are a wholly-owned subsidiary of Zayo Group Holdings, Inc., a Delaware corporation (“Holdings”), which prior to October 16, 2014, was wholly owned by Communications Infrastructure Investments, LLC, a Delaware limited liability company (“CII”)

Our fiscal year ends June 30 each year, and we refer to the fiscal year ended June 30, 2015 as “Fiscal 2015,” the fiscal year ended June 30, 2014 as “Fiscal 2014,” and the fiscal year ended June 30, 2013 as “Fiscal 2013.”

We use the management approach to determine the segment financial information that should be disaggregated and presented. The management approach is based on the manner by which management has organized the segments within the Company for making operating decisions, allocating resources, and assessing performance. As of June 30, 2015, we have three reportable segments as described below:

As a result of the growth of our business from these acquisitions, and capital expenditures and the increased debt used to fund those investing activities, our results of operations for the respective periods presented and discussed herein are not comparable.

On February 23, 2015, we acquired all of the equity interest of the subsidiaries of Latisys Holdings, LLC (“Latisys”), a colocation and infrastructure as a service (“Iaas”) provider for a price of $677.5 million, net of cash acquired. The Latisys acquisition was funded with the proceeds of our January Notes Offering (as defined below).

The Latisys acquisition added colocation and IaaS services through eight datacenters across five markets in Northern Virginia, Chicago, Denver, Orange County and London. The acquired datacenters currently total over 185,000 square feet of billable space and 33 megawatts of critical power.

The results of the acquired Latisys business are included in our operating results beginning February 23, 2015.

On July 1, 2014, we acquired a 96% equity interest in Neo, a Paris-based bandwidth infrastructure company, for purchase consideration of €54.1 million ($73.9 million, net of cash acquired, based on the foreign currency exchange rate on that date). The purchase consideration was funded with cash on hand available from the proceeds of the Sixth Amendment to our Credit Agreement (as defined below). The acquisition of Neo added over 300 route miles of owned Paris metro fiber and approximately 540 on-net buildings to our network. Neo also operates nine colocation centers across France, offering more than 36,000 square feet of datacenter space. The Paris and regional network throughout France were integrated into our existing European network connecting London, Frankfurt, and Amsterdam and the U.S.

The results of the acquired Neo business are included in our operating results beginning July 1, 2014.

On May 16, 2014, we acquired all of the outstanding shares of Geo, which is a London-based dark fiber provider. The purchase consideration of £174.3 million ($292.3 million), net of cash acquired, was paid with a combination of cash on hand and available funds drawn on our Revolver (as defined below).

Geo owns and operates a high capacity fiber network in the United Kingdom, providing dark fiber and colocation services to a variety of high-bandwidth sectors including media companies, service providers, financial services, datacenters, and gaming organizations. The acquisition added over 2,100 route miles to our European network and additional connectivity to 587 on-net buildings.

The results of the acquired Geo business are included in our operating results beginning May 16, 2014.

The table below summarizes the dates and purchase prices (which are net of cash acquired and include assumption of debt and capital leases) of all acquisitions and asset purchases through June 30, 2015.

We completed each of the acquisitions described above, with the exception of Voicepipe and Corelink, with cash raised through combinations of equity issuances and the incurrence of debt. We acquired Voicepipe from certain existing CII equity holders in exchange for CII preferred units, and we acquired Corelink with a combination of cash and CII preferred units.

On July 2, 2012, we and our direct wholly-owned subsidiary Zayo Capital, Inc. (“Zayo Capital”) issued $750.0 million aggregate principal amount of 8.125% senior secured first-priority notes due 2020 (the “2020 Secured Notes”) and $500.0 million aggregate principal amount of 2020 Unsecured Notes. On July 2, 2012, we also entered into a $250.0 million senior secured revolving credit facility (the “Revolver”) and a $1,620.0 million senior secured term loan facility (the “Term Loan Facility”), which are governed by a Credit Agreement (the “Credit Agreement”) that has been subsequently amended. A portion of the net proceeds from the 2020 Secured Notes, 2020 Unsecured Notes and the Term Loan Facility, together with cash on hand and equity contributions, were used to extinguish our prior term loan facility and revolver, to finance the cash tender offer for and subsequent redemption of our prior senior secured notes, to pay the cash consideration for the AboveNet acquisition, and to pay associated fees and expenses.

In connection with the debt extinguishment activities discussed above, we recognized an expense in July 2012 of $65.0 million associated with debt extinguishment costs, including a cash expense of $39.8 million associated with the payment of early redemption fees on our previous indebtedness and non-cash expenses of $17.0 million associated with the write-off of our unamortized debt issuance costs and $8.2 million associated with writing-off the net unamortized discount on the debt balances extinguished.

On October 5, 2012, we and Zayo Capital entered into a second amendment (the “Second Amendment”) to the Credit Agreement governing the Term Loan Facility and Revolver. Under the terms of the Second Amendment, effective October 5, 2012, the interest rate on the Term Loan Facility was adjusted to bear an interest rate at LIBOR plus 4.0% (subject to a 5.25% floor), which represented a decrease of 187.5 basis points from the original Credit Agreement. The Second Amendment also reduced the interest rate on the Revolver by 187.5 basis points.

On February 27, 2013, we and Zayo Capital entered into a Fourth Amendment (the “Fourth Amendment”) to the Credit Agreement. Under the terms of the Fourth Amendment, effective February 27, 2013, the interest rate on the Term Loan Facility was further adjusted to bear interest at LIBOR plus 3.5% (subject to a 4.5% floor). The amended terms represent a downward adjustment of 50 basis points on the spread and a further 25 basis point reduction minimum floor. Under the terms of the Fourth Amendment, the Revolver bore interest at LIBOR plus 3.00%, based on our current leverage ratio, which represented a 50 basis point reduction. The Fourth Amendment also amended certain terms and provisions of the Credit Agreement, including removing the senior secured and total leverage maintenance covenants and increasing the total leverage ratio required to be met in order to incur certain additional indebtedness from 5.00:1.00 to 5.25:1.00 as a multiple of EBITDA (as defined in the Credit Agreement).

In connection with the aforementioned amendments, we incurred early redemption call premiums of $16.2 million and $16.1 million for the Second Amendment and Fourth Amendment, respectively. The early redemption call premiums were paid with cash on hand to the syndicate of creditors in the Term Loan Facility. Prior to the consummation of the amendments, we requested the consent of all creditors holding balances in the Term Loan Facility to the amended terms. $15.3 million and $15.0 million of the early call premium paid to consenting creditors in the Second and Fourth Amendments, respectively, were accounted for as additional debt issuance costs for the modified obligations during the year ended June 30, 2013, which are being amortized over the term of the Term Loan Facility using the effective interest method. The remaining call premium of $0.9 million and $1.1 million associated with the Second and Fourth Amendments, respectively, that was paid to non-consenting creditors has been recorded as a loss on extinguishment of debt on the consolidated statements of operations for the year ended June 30, 2013. Existing and/or new creditors replaced the non-consented commitments, such that the full amount of the Term Loan Facility’s commitments were replaced in both the Second and Fourth Amendments.

In connection with the Second and Fourth Amendments, we recognized an expense of $12.2 million during the year ended June 30, 2013 associated with debt extinguishment costs. The loss on extinguishment of debt

associated with the amendments includes the aforementioned early call premiums paid to non-consenting creditors, non-cash expense associated with the write off of unamortized debt issuance costs and issuance discounts on the debt balances accounted for as an extinguishment, and certain fees paid to third parties involved in the amendments.

On November 26, 2013, we and Zayo Capital entered into a Fifth Amendment (the “Fifth Amendment”) to the Credit Agreement. Under the terms of the Fifth Amendment, the Term Loan Facility was increased by $150.0 million to $1,749.8 million and the interest rate was adjusted to LIBOR plus 3.0% with a minimum LIBOR rate of 1.0%. The amended terms represented a downward adjustment of 50 basis points on the interest rate from the Fourth Amendment. The interest rate on the Revolver was amended to LIBOR plus 2.75% (based on our then current leverage ratio), which represented a downward adjustment of 25 basis points on the interest rate from the Fourth Amendment. In connection with the Fifth Amendment, we did not incur a re-pricing premium.

Also, in connection with the Fifth Amendment, we recognized an expense during the second quarter of Fiscal 2014 of $1.9 million associated with debt extinguishment costs, including cash expense of $1.0 million related to third party costs and non-cash expense of $0.9 million associated with the write-off of our unamortized debt issuance costs and discount on the Term Loan Facility accounted for as an extinguishment. We also incurred an additional $1.5 million in debt issuance costs in the second quarter of Fiscal 2014.

On May 16, 2014, we and Zayo Capital entered into a Sixth Amendment (the “Sixth Amendment”) to the Credit Agreement. Per the terms of the Sixth Amendment, our Term Loan Facility was increased by $275.0 million to $2,015.9 million and bears interest at the existing rate of LIBOR plus 3.0 percent with a minimum LIBOR rate of 1.0 percent. The $275.0 million add-on was priced at 99.5 percent. No other terms of the Credit Agreement were amended. In connection with the Sixth Amendment, we incurred an additional $3.2 million in debt issuance costs and $1.4 million was recorded as a discount.

On December 15, 2014, we redeemed $75.0 million of its outstanding 2020 Secured Notes at a price of 108.125% of the principal amount and $174.4 million of its outstanding 2020 Unsecured Notes at a price of 110.125% (collectively, the “December Notes Redemption”). As part of the December Notes Redemption, we recorded an early redemption call premium of $23.8 million which has been recorded as a loss on extinguishment of debt on the consolidated statements of operations in Fiscal 2015.

On January 23, 2015, we and Zayo Capital (together, the “Issuers”) completed a private offering (the “January Notes Offering”) of $700.0 million aggregate principal amount of 2023 Notes. On March 9, 2015, the Issuers completed a private offering of an additional $730.0 million aggregate principal amount of 2023 Notes at a premium of 1% (the “March Notes Offering”, and together with the January Notes Offering, the “2023 Notes Offerings”) resulting in aggregate gross proceeds for the 2023 Notes of $1,437.3 million. The issue premium of $7.3 million on the March Notes Offering is being accreted against interest expense over the term of the 2023 Notes under the effective interest method. The 2023 Notes bear interest at the rate of 6.00% per year, which is payable on April 1 and October 1 of each year, beginning on October 1, 2015. The 2023 Notes will mature on April 1, 2023. The net proceeds from the January Notes Offering were used to fund the Latisys acquisition (see Note 3—Acquisitions). The net proceeds from the March Notes Offering were used to redeem our remaining $675.0 million 2020 Secured Notes (the “Second Notes Redemption”) at a price of 105.75%. As part of the Second Notes Redemption, we recorded an early redemption call premium of $38.8 million. The call premium has been recorded as a loss on extinguishment of debt on the consolidated statements of operations for the year ended June 30, 2015.

On April 17, 2015, we entered into a Seventh Amendment (the “Seventh Amendment”) to the Credit Agreement. Per the terms of the Seventh Amendment, the Revolver was increased by $200.0 million to $450.0 million, and the maturity date of the Revolver was extended to the earliest of (i) five years after the effective date of the Seventh Amendment, (ii) six months prior to the maturity date of our Term Loan Facility, subject to

repayment or amendment thereof, and (iii) six months prior to the maturity date of the 2020 Unsecured Notes, subject to repayment or amendment thereof. The Seventh Amendment also increased the letter of credit commitment from $30.0 million to $50.0 million and provided that, in the event that the Term Loan Facility was amended or refinanced to remove all financial maintenance covenants, the Fixed Charge Coverage Ratio maintenance requirement would be replaced with a springing Senior Secured Leverage Ratio maintenance requirement applicable only to the Revolver. Further, pursuant to the Seventh Amendment, up to $50.0 of revolving loans and letters of credit may be denominated in or issued in, as applicable, Euros or British Pound Sterling.

On May 6, 2015, we and Zayo Capital issued $350.0 million aggregate principal amount of 2025 Notes. Interest on the 2025 Notes is payable on May 15 and November 15 of each year, beginning on November 15, 2015. The 2025 Notes will mature on May 15, 2025. The net proceeds from the 2025 Notes were used to repay $344.5 million of our Term Loan Facility. As a result of that repayment, we recorded a loss on extinguishment of debt of $8.4 million.

On May 6, 2015, we entered into an Amendment and Restatement Agreement whereby the Credit Agreement was amended and restated in its entirety. The amended and restated Credit Agreement extended the maturity date of all of the outstanding term loans under the Term Loan Facility to May 6, 2021. The interest rate margins applicable to the Term Loan Facility were decreased by 25 basis points to LIBOR plus 2.75% with a minimum LIBOR of 1.0%. In addition, the amended and restated Credit Agreement removed the Fixed Charge Coverage Ratio covenant and replaced such covenant with a springing Senior Secured Leverage Ratio maintenance requirement applicable only to the Revolver, increased certain lien and debt baskets, and removed certain covenants related to collateral.

Interest rates on the Term Loan Facility and Revolver as of June 30, 2015 were 3.75% and 3.0%, respectively.

During Fiscal 2015, 2014, and 2013, we invested, net of stimulus grant reimbursements, $530.4 million, $360.8 million, and $332.6 million, respectively, in capital expenditures primarily to expand our fiber network to support new customer contracts. We expect to continue to make significant capital expenditures in future periods.

Our revenue is comprised predominately of monthly recurring revenue (“MRR”). MRR is related to an ongoing service that is generally fixed in price and paid by the customer on a monthly basis. We also report monthly amortized revenue (“MAR”), which represents the amortization of previously collected upfront charges to customers. Upfront charges are typically related to IRUs structured as pre-payments rather than monthly recurring payments (though we structure IRUs as both prepaid and recurring, largely dependent on the customers’ preference) and installation fees. The last category of revenue we report is other revenue. Other revenue includes credits and adjustments, termination revenue, construction services, and equipment sales.

Our consolidated reported revenue in any given period is a function of our beginning revenue under contract and the impact of organic growth and acquisition activity. Our organic activity is driven by net new sales (“bookings”), gross installed revenue (“installs”) and churn processed (“churn”) as further described below.

Net New Sales. Net new sales (“bookings”) represent the dollar amount of orders, to be recorded as MRR and MAR upon installation, in a period that have been signed by the customer and accepted by our service

delivery organization. The dollar value of bookings is equal to the monthly recurring price that the customer will pay for the services and/or the monthly amortized amount of the revenue that we will recognize for those services. To the extent a booking is cancelled by the customer prior to it being installed, it is subtracted from the total bookings number in the period that it is cancelled. Bookings do not immediately impact revenue until they are installed (gross installed revenue).

Gross Installed Revenue. Installs are the amount of MRR and MAR for services that have been installed, tested, accepted by the customer, and have been recognized in revenue during a given period. Installs include new services, price increases, and upgrades.

Churn Processed. Churn is any negative change to MRR and MAR. Churn includes disconnects, negative price changes, and disconnects associated with upgrades or replacement services. For each period presented, disconnects associated with attrition and upgrades are the drivers of churn, accounting for more than 80% of negative changes in MRR and MAR while price changes account for less than 20%. Monthly churn is also presented as a percentage of MRR and MAR (“churn percentage”).

Given the size and amount of acquisitions we have completed, we have estimated the revenue growth rate associated with our organic activity in each period reported. Our estimated organic growth rate is calculated by adding an estimate of the acquired companies’ revenue for the reporting period prior to the date of inclusion in our results of operations, and then calculating the growth rate between the two reported periods. The estimate of acquired annual revenue is based on the acquired companies’ revenues for the most recent quarter prior to close (including estimated purchase accounting adjustments) multiplied by four. If, in calculating our estimated organic growth rates, we were to use the actual revenue results for the four quarters preceding the closing of each of our acquisitions, our estimated organic growth rates would be higher than the estimated organic growth rates presented. If we were to use acquired annualized revenue, calculated by taking each acquired company’s revenues for the most recent quarter prior to the closing of such acquisition and multiplying by four, our estimated organic growth rates would be lower than the estimated organic growth rates presented.

We have foreign subsidiaries that enter into contracts with customers and vendors in currencies other than the United States Dollar (“USD”)—principally the Great British Pound (“GBP”) and to a lesser extent the Euro. Changes in foreign currency exchange rates impact our revenue and expenses each period. The comparisons excluding the impact of foreign currency exchange rates assume exchange rates remained constant at the comparative period rate.

Our operating costs and expenses consist of network expense (“Netex”), compensation and benefits, network operations expense (“Netops”), stock-based compensation expense, other expenses, and depreciation and amortization.

Netex consists of third-party network service costs resulting from our leasing of certain network facilities, primarily leases of circuits and dark fiber, from carriers to augment our owned infrastructure, for which we are generally billed a fixed monthly fee. Netex also includes colocation facility costs for rent and license fees paid to the landlords of the buildings in which our colocation business operates, along with the utility costs to power those facilities. While increases in demand for our services will drive additional operating costs in our business, consistent with our strategy of leveraging our owned infrastructure assets, we expect to primarily utilize our existing network infrastructure or build new network infrastructure to meet the demand. In limited circumstances, we will augment our network with additional circuits or services from third-party providers. Third-party network service costs include the upfront cost of the initial installation of such circuits. Such costs are included in operating costs in our consolidated statements of operations over the respective service period.

development of business support systems) are capitalized and amortized to operating costs and expenses. Compensation and benefits expenses related to the departments attributed to generating revenue are included in our operating costs line item while compensation and benefits expenses related to the sales, product, and corporate departments are included in our selling, general and administrative expenses line item of our consolidated statements of operations.

Netops expense includes all of the non-personnel related expenses of operating and maintaining our network infrastructure, including contracted maintenance fees, right-of-way costs, rent for cellular towers and other places where fiber is located, pole attachment fees, and relocation expenses. Such costs are included in operating costs in our consolidated statements of operations.

Prior to Holdings’ initial public offering, our stock-based compensation expense contained two components, CII common unit awards classified as liabilities and, to a lesser extent, CII preferred unit awards classified as equity. For the CII common units granted to employees and directors, we recognized an expense equal to the fair value of all of those common units that vest during the period plus the change in fair value of previously vested units, and recorded a liability in respect of those amounts. Following the IPO, our stock-based compensation expense contains three components: previously granted CII common unit awards, CII preferred unit awards and restricted stock unit awards made under our new equity compensation program. For previously granted CII common unit awards, following the IPO, we amortize the offering date fair value of those units (including unvested units) over the vesting period based on expected settlement behavior with a corresponding adjustment to equity, as the awards no longer have cash settlement features. For previously granted CII preferred units, we use the straight line method, over the vesting period, to amortize the fair value of those units, as determined on the date of grant. We recognize stock-based compensation expense for restricted stock unit awards granted to employees, members of management, and directors based on their estimated grant date fair value on a straight line basis over the requisite service period, as adjusted for an estimate of forfeitures. These restricted stock unit awards are primarily equity classified, except certain awards that have not yet been granted to employees. Following Holdings’ initial public offering, subsequent changes in the fair value of the CII preferred and common units and restricted stock unit awards granted generally do not affect the amount of expense we recognize.

Stock-based compensation expense is included, based on the responsibilities of the awarded recipient, in either our operating costs or selling, general and administrative expenses in our consolidated statements of operations.

Other expenses include expenses such as property tax, franchise fees, colocation facility maintenance, travel, office expense and other administrative costs. Other expenses are included in both operating costs and selling, general and administrative expenses depending on their relationship to generating revenue or association with sales and administration.

Transaction costs include expenses associated with professional services (i.e. legal, accounting, regulatory, etc.) rendered in connection with acquisitions or disposals (including spin-offs), travel expense, severance expense incurred on the date of acquisition or disposal, and other direct expenses incurred that are associated with signed and/or closed acquisitions or disposals. Transaction costs are included in selling, general and administrative expenses in our consolidated statements of operations.

Refer to “Selected Historical Consolidated Financial Information” for additional financial information for the indicated periods.

Our total revenue increased by $217.4 million, or 19%, to $1,347.1 million for the year ended June 30, 2015, from $1,129.7 million for the year ended June 30, 2014. The increase in revenue was driven by our organic growth as well as Fiscal 2014 and 2015 acquisitions.

We estimate that the period-over-period organic growth was approximately 7%. Our organic growth was driven by installs that exceeded churn over the course of both periods, resulting from continued strong demand for bandwidth infrastructure services broadly across our service territory and customer verticals. Additional underlying revenue drivers included:

We estimate that the period-over-period acquisition-related revenue growth was approximately 12%.

The average exchange rate between the USD and GBP strengthened by 3.2% during the year ended June 30, 2015. Normalizing our revenue to exclude the impact of foreign currency exchange rate fluctuations, we estimate that revenue would have increased between the year ended June 30, 2015 and June 30, 2014 by an additional $2.2 million.

Physical Infrastructure. Revenue from our Physical Infrastructure segment increased by $167.0 million, or 34%, to $662.4 million from $495.4 million, for the years ended June 30, 2015 and 2014, respectively. The increase was a result of both organic and acquisition related growth.

Dark Fiber is the largest Strategic Product Group within the segment and benefited from continued growth in infrastructure demand. Our FTT and zColo products also contributed to the segment’s growth. Bookings of MRR and MAR for the year ended June 30, 2015 were $11.5 million (with a total contract value of approximately $1,426.0 million), an increase from the $0.9 million in bookings for the same period in the prior year. Gross installs were $9.7 million for Fiscal 2015, compared to $8.1 million for Fiscal 2014. The monthly churn percentage was consistent between the two periods at 0.8%, resulting in total churn processed of $5.0 million compared to $3.9 million in the same period in the prior year.

Cloud and Connectivity. Revenue from our Cloud and Connectivity segment increased by $55.3 million, or 9%, to $661.5 million from $606.2 million for the years ended June 30, 2015 and 2014, respectively. The increase was a result of both organic and acquisition related growth.

Bookings of MRR and MAR increased from $11.1 million to $12.7 million between the two comparative periods, with a total contract value of approximately $405.0 million for the year ended June 30, 2015. Gross installs were $12.7 million for the year ended June 30, 2015, compared to $11.5 million in the prior year. The monthly churn percentage decreased from 1.7% to 1.6%, resulting in total churn processed of $9.9 million compared to $10.2 million in the same period in the prior year.

Other. Revenue from our Other segment decreased by $4.9 million, or 17%, to $23.2 million from $28.1 million, for the years ended June 30, 2015 and 2014, respectively. The decrease was the result of the non-recurring nature of revenue related to the Other segment, which had slightly lower sales in Fiscal 2015 as compared to Fiscal 2014. The Other segment represented approximately 1.7% of our total revenue during the year ended June 30, 2015.

The following table reflects the stratification of our revenues during these periods. The substantial majority of our revenue continued to come from recurring payments from customers under contractual arrangements.

Our operating costs increased by $111.7 million, or 10% to $1,177.8 million for Fiscal 2015 from $1,066.1 million for Fiscal 2014. The increase in consolidated operating costs was primarily due to increased costs as a result of Fiscal 2015 and Fiscal 2014 acquisition related growth, and organic growth of our network, partially offset by a $53.0 million decrease in stock-based compensation.

Physical Infrastructure. Physical Infrastructure operating costs increased by $58.0 million, or 11%, to $599.1 million for Fiscal 2015 from $541.1 million for Fiscal 2014. The increase in operating costs and expenses was primarily a result of the timing of our Fiscal 2015 and Fiscal 2014 acquisitions and additional costs associated with the organic growth of our network partially offset by a decrease in stock-based compensation.

Cloud and Connectivity. Cloud and Connectivity operating costs increased by $48.3 million, or 10%, to $550.5 million for Fiscal 2015 from $502.2 million for Fiscal 2014. The increase in operating costs and expenses was primarily a result of the timing of our Fiscal 2015 and Fiscal 2014 acquisitions.

Other. Other operating costs increased by $5.4 million, or 24%, to $28.2 million for Fiscal 2015 from $22.8 million for Fiscal 2014 as a result of decreased revenue from ZPS.

The table below sets forth the components of our operating costs and expenses during the years ended June 30, 2015 and 2014:

Netex. Our Netex increased by $27.8 million, or 18%, to $178.3 million for Fiscal 2015 from $150.5 million for Fiscal 2014. The increase in Netex was primarily due to increased facility costs related to the colocation acquisitions completed in Fiscal 2015 and Fiscal 2014, partially offset by cost savings, as planned network related synergies were realized. Netex as a percentage of total revenue remained at 13% for Fiscal 2015 and 2014.

Compensation and Benefits Expenses. Compensation and benefits expenses increased by $31.7 million, or 25%, to $158.6 million for Fiscal 2015 from $126.9 million for Fiscal 2014.

The increase in compensation and benefits reflected the increase in headcount during Fiscal 2015 to support our growing business, including certain employees retained from businesses acquired since June 30, 2014, and employer matching of employee 401(k) contributions beginning in the fourth quarter of Fiscal 2014.

Network Operations Expenses. Network operations expenses increased by $22.0 million, or 17%, to $152.5 million for Fiscal 2015 from $130.5 million for Fiscal 2014. The increase principally reflected the growth of our network assets and the related expenses of operating that expanded network. Our total network route miles increased approximately 6% to 85,644 miles at June 30, 2015 from 80,861 miles at June 30, 2014.

Other Expenses. Other expenses increased by $13.8 million, or 22%, to $75.6 million for Fiscal 2015, from $61.8 million Fiscal 2014. The increase was primarily the result of additional expenses attributable to our Fiscal 2014 and 2015 acquisitions.

Transaction Costs. Transaction costs increased by $1.4 million, or 31%, to $5.9 million for Fiscal 2015 from $4.5 million for Fiscal 2014. The increase was due to higher transaction-related costs associated with our Fiscal 2015 acquisitions.

Stock-Based Compensation. Stock-based compensation expense decreased by $53.0 million, or 21%, to $200.7 million for Fiscal 2015 from $253.7 million for Fiscal 2014.

Prior to Holdings’ initial public offering, we recognized changes in the fair value of the common units through increases or decreases in stock-based compensation expense and adjustments to the related stock-based compensation liability. This liability was impacted by changes in the estimated value of the common units, number of vested common units, and distributions made to holders of the common units. In connection with the IPO, we re-measured the fair value of the common units at the offering date based on various projections involving future stock performance, vesting and forfeitures. The fair value of unvested common units on the offering date is recognized as stock-based compensation expense ratably over the remaining vesting period. For restricted stock unit awards, expense is recognized based on the estimated fair value of the units awarded over the requisite service period. The estimated fair value of the restricted stock unit awards is impacted by various factors, including market and performance-based targets, expectations regarding future stock performance, the measurement or performance period, and forfeiture rates. The higher Fiscal 2014 stock-based compensation expense is primarily driven by increases to the estimated fair value of our liability classified common unit awards.

Depreciation and amortization expense increased by $68.0 million, or 20%, to $406.2 million for Fiscal 2015 from $338.2 million for Fiscal 2014. The increase was primarily the result of depreciation related to capital expenditures since June 30, 2014 and acquisition-related growth.

The table below sets forth the components of our total other expense, net for the years ended June 30, 2015 and 2014.

Interest expense. Interest expense increased by $10.5 million, or 5%, to $214.0 million from $203.5 million for the years ended June 30, 2015 and 2014, respectively. The increase was primarily a result of our increased indebtedness and changes in the fair value of our interest rate swaps, partially offset by reduced interest rates on our outstanding indebtedness as a result of our Fiscal 2015 debt transactions.

Loss on extinguishment of debt. During the year ended June 30, 2015, we redeemed our $750.0 million 2020 Secured Notes and a portion of our 2020 Unsecured Notes and repaid $344.5 million on our Term Loan Facility. As part of the redemptions and early payment on the Term Loan Facility, we paid early redemption call premiums totaling $62.6 million and recorded an expense of $31.7 million related to unamortized debt issuance costs and discounts associated with the extinguished indebtedness. These expenses were recorded as a loss on extinguishment of debt during the year ended June 30, 2015.

Foreign currency (loss)/gain on intercompany loans. Foreign currency (loss)/gain on intercompany loans decreased to a loss of $24.4 million for the years ended June 30, 2015, from a gain of $4.7 million for the year ended June 30, 2014. This non-cash loss was driven by the strengthening of the USD against the GBP and the related impact on intercompany loans entered into by foreign subsidiaries in their functional currency.

Income tax expense decreased over the prior year by $49.0 million, to an income tax benefit of $8.7 million for Fiscal 2015, from an income tax expense of $40.3 million for Fiscal 2014. Our provision for income taxes included both the current provision and a provision for deferred income tax expense resulting from timing differences between tax and financial reporting accounting bases. In addition, as a result of our stock-based compensation related to our CII common and preferred units and certain transaction costs not being deductible for income tax purposes, our effective tax rate was higher than the statutory rate.

The following table reconciles an expected tax provision based on a statutory federal tax rate applied to our earnings before income tax to our actual provision for income taxes (in millions):

Our total revenue increased by $118.7 million, or 12%, to $1,129.7 million for Fiscal 2014, from $1,011.0 million for Fiscal 2013. The increase in revenue was driven by our organic growth as well as the timing of our Fiscal 2014 and Fiscal 2013 acquisitions.

We estimate that we achieved an organic growth rate of approximately 6% year-over-year. Our organic growth was driven by installs that exceeded churn over the course of both periods, resulting from continued strong demand for bandwidth infrastructure services broadly across our service territory and customer industry verticals. Further underlying revenue drivers included:

We estimate that the period-over-period acquisition-related revenue growth was approximately 6%. Multiple Fiscal 2014 and Fiscal 2013 acquisitions impacted revenue growth between the two periods. The five Fiscal 2014 acquisitions were completed on August 1, 2013, October 1, 2013, October 2, 2013, March 4, 2014, and May 16, 2014 and were included in our Fiscal 2014 results for approximately eleven, nine, nine, four, and one month(s), respectively. The Fiscal 2014 acquisitions represented smaller acquisitions of dark fiber and colocation-only providers, with the exception of Geo, which was a larger acquisition of a European-based dark fiber and wavelength services provider completed in the fourth quarter of Fiscal 2014. The six Fiscal 2013 acquisitions were completed at various times throughout the year, although the largest (AboveNet) closed on July 2, 2012 and was fully included in our annual results for the year ended June 30, 2014 and 2013 and therefore was not a contributor to the period-over-period acquisition growth. The other acquisitions were included in our results of operations for only part of Fiscal 2013 compared to their inclusion for all of Fiscal 2014.

Physical Infrastructure. Revenues from our Physical Infrastructure segment increased by $82.4 million, or 20%, to $495.4 million for Fiscal 2014 from $413.0 million for Fiscal 2013.

Dark fiber is the largest Strategic Product Group within the segment and benefited from continuing growth in infrastructure demand. Our FTT and zColo products also contributed to the segment’s growth. Bookings of MRR and MAR for the year ended June 30, 2014, were $10.6 million (with a total contract value of approximately $1,300.0 million), nearly double the $6.3 million in bookings for the prior annual period. Installs were $8.1 million for Fiscal 2014, compared to $6.5 million for the prior annual period. The monthly churn percentage decreased between the two periods to 0.8% from 0.9%. All of the Fiscal 2014 acquisitions impacted the Physical Infrastructure segment revenues as FiberLink (dark fiber) and CoreLink and CoreXchange (both colocation) were Physical Infrastructure-only businesses and Geo was primarily Physical Infrastructure (dark fiber).

Cloud and Connectivity. Revenues from our Cloud and Connectivity segment increased by $35.7 million, or 6%, to $606.2 million for Fiscal 2014, from $570.5 million for Fiscal 2013.

Growth was strongest in the segment’s Ethernet and IP Strategic Product Groups, driven by customer demand and increased effectiveness in marketing these products. Wavelength revenue growth was dampened by churn, including price concessions we proactively offered in exchange for customer contract extensions. SONET is a legacy product, and its revenue declined between the two periods, consistent with our expectations. Bookings of MRR and MAR decreased slightly to $11.1 million from $11.3 million between the two periods, with a total contract value of approximately $420.0 million, for the year ended June 30, 2014. Installs were $11.5 million for

the year ended June 30, 2014, compared to $11.8 million for the comparative annual period. The monthly churn percentage remained consistent at 1.7% for the two periods, resulting in total churn processed of $10.2 million compared to $9.6 million in the prior fiscal year. The Cloud and Connectivity period-over-period revenue results were primarily influenced by the carryover impacts from the Fiscal 2013 acquisitions, as the Fiscal 2014 acquisitions mostly impacted the Physical Infrastructure segment.

Other. Revenue from our Other segment, consisting of ZPS, increased by 2%, or $0.6 million, to $28.1 million for Fiscal 2014 from $27.5 million for Fiscal 2013. The increase was largely driven by a one-time equipment sale in the fourth quarter of Fiscal 2014. The Other segment represented approximately 3% of our total revenue.

Physical Infrastructure. Physical Infrastructure operating costs and expenses increased by $166.0 million, or 44%, to $541.1 million for Fiscal 2014 from $375.1 million for Fiscal 2013. The increase in operating costs and expenses was primarily a result of the acquisitions of Geo, CoreXchange, Fiberlink, Access, Corelink and CoreNAP, in Fiscal 2014 and Fiscal 2013.

Cloud and Connectivity. Cloud and Connectivity operating costs and expenses increased by $4.7 million, or 1%, to $502.2 million for Fiscal 2014 from $497.5 million for Fiscal 2013. The relatively flat operating costs and expenses in relation to the 6% increase in revenue for Cloud and Connectivity was primarily due to realized network-related cost synergies related to our acquisitions, and, to a lesser extent, ongoing off-net circuit cost reduction projects.

Other. Other operating costs and expenses decreased by $1.4 million, or 6%, to $22.8 million for Fiscal 2014 from $24.2 million for Fiscal 2013. The reduction in other operating costs and expenses was primarily attributable to a reduction in MRR.

The table below sets forth the components of our operating costs and expenses during the years ended June 30, 2014 and 2013.

Netex. Our Netex increased by $4.6 million, or 3%, to $150.5 million for Fiscal 2014 from $145.9 million for Fiscal 2013. The increase in Netex was primarily due to increased facility costs related to the colocation acquisitions completed in Fiscal 2013 and Fiscal 2014, partially offset by cost savings, as planned network related synergies were realized. Netex as a percentage of total revenue decreased to 13% from 15% as a result of cost reductions and because our incremental revenue typically has less third-party network service costs associated with it than the existing base of revenue.

Compensation and Benefits Expenses. Compensation and benefits expenses increased by $3.5 million, or 3%, from $123.4 million for Fiscal 2013 to $126.9 million for Fiscal 2014.

The increase in compensation and benefits reflected the increase in headcount during Fiscal 2014 to support our growing business, including certain employees retained from businesses acquired since June 30, 2013, and employer matching of employee 401(k) contributions beginning in the fourth quarter of Fiscal 2014. This was partially offset by a reduction in bonus payout as the average payout for the year ended June 30, 2013 was approximately 130% of target as compared to approximately 100% of target for the year ended June 30, 2014.

Netops. Netops expense increased by $9.6 million, or 8%, to $130.5 million for Fiscal 2014 from $120.9 million for Fiscal 2013. The increase principally reflected the growth of our network assets and the related expenses of operating that expanded network. Our total network route miles increased approximately 7%, to 80,860 miles at June 30, 2014, from 75,839 miles at June 30, 2013.

Other Expenses. Other expenses increased by $1.2 million, or 2%, to $61.8 million for Fiscal 2014 from $60.6 million for Fiscal 2013. The increase was primarily the result of additional expenses attributable to our Fiscal 2014 and Fiscal 2013 acquisitions, which were partially offset by the receipt of $3.8 million in connection with an escrow settlement relating to the 360networks acquisition during the second quarter of Fiscal 2014.

Transaction Costs. Transaction costs decreased by $9.7 million, or 68%, to $4.5 million for Fiscal 2014 from $14.2 million for Fiscal 2013. The decrease was due to higher transaction-related costs in the first quarter of Fiscal 2013 associated with the AboveNet acquisition, partially offset by the transaction-related costs associated with the Geo and Neo acquisitions in Fiscal 2014.

Stock-Based Compensation. Stock-based compensation expense increased by $147.9 million, or 140%, from $105.8 million for Fiscal 2013 to $253.7 million for Fiscal 2014.

Depreciation and amortization expense increased by $13.7 million, or 4%, to $338.2 million for Fiscal 2014 from $324.5 million for Fiscal 2013. The increase was primarily the result of depreciation related to capital expenditures since June 30, 2013 and acquisition-related growth.

The table below sets forth the components of our total other expense, net for the years ended June 30, 2014 and 2013.

Interest Expense. Interest expense increased by $1.0 million, or less than 1%, to $203.5 million for Fiscal 2014, from $202.5 million for Fiscal 2013. The increase was primarily a result of additional interest expense related to the $150.0 million and $275.0 million add-ons to our Term Loan Facility during the second and fourth quarters of Fiscal 2014, respectively. Also contributing to the increase in interest expense was the impact of changes in market value of our interest rate swaps during the year ended June 30, 2014 as compared to the year ended June 30, 2013. The change in market value was additional interest expense of $4.7 million for the year ended June 30, 2014 as compared to a reduction in interest expense of $2.6 million for the year ended June 30, 2013, representing a year over year increase in interest expense of $7.3 million. These increases were partially offset by a decrease in interest expense resulting from the amendments to our Credit Agreement during the second and third quarters of Fiscal 2013 and second quarter of Fiscal 2014 to lower the interest rates on our Term Loan Facility and Revolver, in addition to quarterly principal payments on our Term Loan Facility, which reduced our outstanding debt obligations.

Loss on Extinguishment of Debt. In connection with the debt refinancing activities during Fiscal 2014, we recognized an expense of $1.9 million associated with debt extinguishment costs, including a cash expense of $0.9 million associated with the payment of third party costs and non-cash expenses of $1.0 million, consisting of $0.7 million associated with the write-off of unamortized debt issuance costs and $0.3 million associated with the write-off of the net unamortized discount on the extinguished debt balances.

In connection with the debt refinancing activities during the Fiscal 2013, we incurred an expense of $77.3 million associated with debt extinguishment costs, including a cash expense of $41.9 million associated with the payment of early redemption fees and other third party expenses on our previous indebtedness and non-cash expenses, including $35.4 million associated with the write-off of unamortized debt issuance costs and unamortized discounts.

Income tax expense increased over the prior year by $61.5 million, from an income tax benefit of $21.8 million for Fiscal 2013 to an income tax expense of $40.3 million for Fiscal 2014. Our provision for income taxes included both the current and deferred provision for income tax expense resulting from timing differences between tax and financial reporting accounting bases. In addition, as a result of our pre-IPO stock-based compensation and certain transaction costs not being deductible for income tax purposes, our effective tax rate was higher than the statutory rate.

The following table reconciles our expected tax benefit based on the statutory federal tax rate applied to our earnings before income taxes to our actual (benefit)/provision for income taxes:

The following table reconciles our expected tax provision based on the statutory federal tax rate applied to our earnings before income taxes to our actual provision/(benefit) for income taxes:

We define Adjusted EBITDA as earnings/(loss) from continuing operations before interest, income taxes, depreciation and amortization (“EBITDA”) adjusted to exclude acquisition or disposal-related transaction costs, losses on extinguishment of debt, stock-based compensation, unrealized foreign currency gains (losses) on intercompany loans, and non-cash income (loss) on equity and cost method investments. We use Adjusted EBITDA to evaluate operating performance, and this financial measure is among the primary measures used by management for planning and forecasting for future periods. We believe that the presentation of Adjusted EBITDA is relevant and useful for investors because it allows investors to view results in a manner similar to the method used by management and facilitates comparison of our results with the results of other companies that have different financing and capital structures.

We also monitor Adjusted EBITDA because our subsidiaries have debt covenants that restrict their borrowing capacity that are based on a leverage ratio, which utilizes a modified EBITDA, as defined in our Credit Agreement and the indentures governing our Existing Notes. The modified EBITDA is consistent with our definition of Adjusted EBITDA; however, it includes the pro forma Adjusted EBITDA of and expected cost synergies from the companies acquired by us during the quarter for which the debt compliance certification is due.

Adjusted EBITDA results, along with other quantitative and qualitative information, are also utilized by management and our compensation committee for purposes of determining bonus payouts to employees.

Our computation of Adjusted EBITDA may not be comparable to other similarly titled measures computed by other companies because all companies do not calculate Adjusted EBITDA in the same fashion.

Reconciliations from segment and consolidated Adjusted EBITDA to net (loss)/earnings from operations are as follows:

Our primary sources of liquidity have been cash provided by operations, equity contributions, and incurrence of debt. Our principal uses of cash have been for acquisitions, capital expenditures, and debt service requirements. We anticipate that our principal uses of cash in the future will be for acquisitions, capital expenditures, working capital, and debt service.

We have financial covenants under the indentures governing our Existing Notes and our Credit Agreement that, under certain circumstances, restrict our ability to incur additional indebtedness. The indenture governing our 2020 Unsecured Notes limits any increase in our secured indebtedness (other than certain forms of secured indebtedness expressly permitted under such indenture) to a pro forma secured debt ratio of 4.50 times our previous quarter’s annualized modified EBITDA (as defined in the indenture) and limits our incurrence of additional indebtedness to a total indebtedness ratio of 5.25 times the previous quarter’s annualized modified EBITDA. The indentures governing the 2023 Notes and the 2025 Notes limit any increase in our secured indebtedness (other than certain forms of secured indebtedness expressly permitted under such indentures) to a pro forma secured debt ratio of 4.50 times our previous quarter’s annualized modified EBITDA (as defined in the indentures), and limit our incurrence of additional indebtedness to a total indebtedness ratio of 6.00 times the previous quarter’s annualized modified EBITDA. The Credit Agreement also contains a covenant, applicable only to the Revolver, that we maintain a senior secured leverage ratio below 5.25:1.00 at any time when the aggregate principal amount of loans outstanding under the Revolver is greater than 35% of the commitments under the Revolver. The Credit Agreement also requires us and our subsidiaries to comply with customary affirmative and negative covenants, including covenants restricting the ability of us and our subsidiaries, subject to specified exceptions, to incur additional indebtedness, make additional guaranties, incur additional liens on assets, or dispose of assets, pay dividends, or make other distributions, voluntarily prepay certain other indebtedness, enter into transactions with affiliated persons, make investments and amend the terms of certain other indebtedness.

As of June 30, 2015, we had $308.0 million in cash and cash equivalents and a working capital surplus of $178.9 million. Cash and cash equivalents consist of amounts held in bank accounts and highly-liquid U.S. treasury money market funds. Additionally, as of June 30, 2015, we had $440.8 million available under our Revolver, subject to certain conditions.

Our capital expenditures, net of stimulus grants, increased by $169.6 million, or 47%, during the year ended June 30, 2015 as compared to the year ended June 30, 2014, to $530.4 million from $360.8 million, respectively. The increase in capital expenditures is a result of meeting the needs of our larger customer base resulting from our acquisitions and organic growth. We expect to continue to invest in our network for the foreseeable future. These capital expenditures, however, are expected to primarily be success-based; that is, in most situations, we will not invest the capital until we have an executed customer contract that supports the investment.

As part of our corporate strategy, we continue to be regularly involved in discussions regarding potential acquisitions of companies and assets, some of which may be quite large. We expect to fund such acquisitions with cash from operations, debt issuances (including available borrowings under our Revolver), equity contributions, and available cash on hand. We regularly assess our projected capital requirements to fund future growth in our business, repay our debt obligations, and support our other general corporate and operational needs, and we regularly evaluate our opportunities to raise additional capital. As market conditions permit, we may refinance existing debt, issue new debt securities through the capital markets, or obtain additional bank financing to fund our projected capital requirements or provide additional liquidity.

We believe that our cash flows from operating activities, in addition to cash and cash equivalents currently on-hand, will be sufficient to fund our operating activities and capital expenditures for the foreseeable future, and in any event for at least the next 12 to 18 months. Given the generally volatile global economic climate, no assurance can be given that this will be the case.

We regularly consider acquisitions and additional strategic opportunities, including large acquisitions, which may require additional debt or equity financing.

The following table sets forth the components of our cash flows for the years ended June 30, 2015, 2014 and 2013.

Net cash flows from operating activities increased by $45.0 million to $607.0 million from $562.0 million during the years ended June 30, 2015 and 2014, respectively.

Net cash flows from operating activities during the year ended June 30, 2015 include the net loss of $155.1 million, plus the add backs of non-cash items deducted in the determination of net loss, principally depreciation and amortization of $406.2 million, stock-based compensation expense of $200.7 million, foreign currency loss on intercompany loans of $24.4 million and non-cash cash interest expense of $19.7 million plus an add back for $94.3 million associated with a loss on extinguishment of debt, partially offset by the deferred tax benefit of $13.2 million. Also contributing to the cash provided by operating activities were additions to deferred revenue of $149.1 million, less amortization of deferred revenue of $72.1 million. Cash flow during the period was reduced by the net change in working capital components of $49.8 million. The $49.8 million cash outflow associated with the change in working capital components was primarily driven by increases in trade receivables of $11.2 million, decrease of accounts payable and accrued liabilities of $22.9 million and increases in other assets and liabilities of $14.4 million.

Net cash flows from operating activities during the year ended June 30, 2014 represents our net loss of $177.1 million, plus the add back to our net loss of non-cash items deducted in the determination of net loss, principally depreciation and amortization of $338.2 million, non-cash interest expense of $22.1 million, the deferred tax provision of $26.9 million, stock-based compensation expense of $253.7 million and loss on extinguishment of debt of $1.9 million. Also contributing to the cash provided by operating activities were additions to deferred revenue of $163.8 million, less amortization of deferred revenue of $55.6 million. Cash flow during the period was increased by the net change in working capital components of $(9.1) million.

The increase in net cash flows from operating activities during the year ended June 30, 2015 as compared to the year ended June, 2014 is primarily a result of additional earnings from organic growth and synergies realized from our Fiscal 2014 and Fiscal 2015 acquisitions, offset in part by increased interest and tax payments.

Net cash flows from operating activities increased by $161.6 million, or 40%, to $566.5 million from $404.9 million during the years ended June 30, 2014 and 2013, respectively.

Net cash flows from operating activities during the year ended June 30, 2013 represents the loss from operations of $141.9 million, plus the add backs of non-cash items deducted in the determination of net loss, principally depreciation and amortization of $324.5 million, stock-based compensation expense of $105.8 million, losses on extinguishment of debt of $77.3 million, additions to deferred revenue of $61.7 million and non-cash interest expense of $12.3 million, offset by amortization of deferred revenue of $43.1 million and deferred tax provision of $23.5 million, plus the net change in working capital components.

The increase in net cash flows from operating activities during the year ended June 30, 2014 as compared to the year ended June 30, 2013 is primarily a result of additional earnings from our organic growth, a higher volume of upfront IRU payments, cost synergies realized from our acquisitions and interest expense savings from our refinancings.

We used cash in investing activities of $1,386.1 million, $754.1 million and $2,804.0 million during the years ended June 30, 2015, 2014 and 2013, respectively.

During the year ended June 30, 2015, our principal uses of cash for investing activities were $530.4 million in additions to property and equipment and $855.7 million in net cash paid for acquisitions.

During the year ended June 30, 2014, our principal uses of cash for investing activities were $360.8 million in additions to property and equipment and $393.0 million in net cash paid for acquisitions.

During the year ended June 30, 2013, our principal uses of cash for investing activities were $323.3 million in additions to property and equipment, net of stimulus grant reimbursements and $2,483.4 million in net cash paid for acquisitions. Our largest acquisition in Fiscal 2013 was our $2,210.0 million acquisition of AboveNet.

Our net cash provided by financing activities was $793.5 million, $397.2 million and $2,340.0 million during the years ended June 30, 2015, 2014 and 2013, respectively.

Our cash flows provided by financing activities during the year ended June 30, 2015 are primarily comprised of $1,787.3 million from debt proceeds and $385.0 million of proceeds from equity contributions. These were partially offset by $1,292.0 million of principal payments on long-term debt and capital lease obligations, $62.6 million of early redemption fees on debt extinguished and $24.2 million of debt issuance costs.

Our cash flows provided by financing activities during the year ended June 30, 2014 are primarily comprised of $423.6 million from debt proceeds, partially offset by $25.9 million of principal payments on long-term debt and capital lease obligations and $4.9 million in debt issuance costs.

Our cash flows from financing activities during the year ended June 30, 2013 primarily consist of $3,189.3 million from the proceeds from long-term debt, $343.8 million in equity contributions from CII and $22.6 million in net transfers of cash out of restricted cash accounts. These cash inflows were partially offset by $83.1 million in debt issuance costs, $1,058.6 million in principal repayments on long-term debt and capital lease obligations and $72.1 million in early redemption fees on debt extinguishments.

The following table represents a summary of our estimated future payments under contractual cash obligations as of June 30, 2015 for continuing operations. Changes in our business needs, cancellation provisions, changing interest rates and other factors may result in actual payments differing from these estimates. We cannot provide certainty regarding the timing and amounts of these future payments.

Our operating leases and purchase commitments include expected payments for our operating facilities, network services and capacity, communications equipment, and maintenance obligations. Our purchase commitments are primarily success-based, meaning that before we commit resources to expand our network, we have a signed customer contract that will provide us with an attractive return on the required capital. The contractual long-term debt payments, above, include an estimate of future interest expense based on the interest rates in effect on our floating rate debt obligations as of the most recent balance sheet date.

Cash payments for interest, net of capitalized interest, which are reflected in our cash flows from operating activities, during the year ended June 30, 2015 were $191.2 million and represent 31% of our cash flows from operating activities before interest expense. We also made cash payments related to principal payments on our long-term debt and capital lease obligations of $23.1 million (exclusive of the impact of redemption and refinancing transactions), which are reflected in our cash flows from financing activities, and represent 4% of our cash flows from operating activities.

We do not have any special purpose or limited purpose entities that provide off-balance sheet financing, liquidity, or market or credit risk support and we do not engage in leasing, hedging, or other similar activities that expose us to any significant liabilities that are not (i) reflected on the face of the consolidated financial statements, (ii), or disclosed in Note 14-Commitments and Contingencies to our audited consolidated financial statements, or in the Contractual Cash Obligations table included above.

On April 7, 2015, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) 2015-03, Simplifying the Presentation of Debt Issuance Costs, which requires debt issuance costs related to a recognized debt liability to be presented on the balance sheet as a direct deduction from the debt liability, similar to the presentation of debt discounts. Prior to the issuance of ASU 2015-03, debt issuance costs were required to be presented as deferred charge assets, separate from the related debt liability. ASU 2015-03 does not change the recognition and measurement requirements for debt issuance costs. The Company early-adopted ASU 2015-03 as of the end of Fiscal 2015, and applied its provisions retrospectively. The adoption of ASU 2015-03 resulted in the reclassification of $71.0 million and $89.4 million of unamortized debt issuance costs related to the Company’s Existing Notes from other non-current assets to long-term debt within its consolidated balance sheets as of both June 30, 2015 and June 30, 2014, respectively.

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers, which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The ASU will replace most existing revenue recognition guidance in GAAP when it becomes effective. In July 2015, the FASB deferred the effective date to annual reporting periods and interim reporting periods within annual reporting periods beginning after December 15, 2017. Early adoption is permitted as of the original effective date or annual reporting periods and interim reporting periods within annual reporting periods beginning after December 15, 2016. The standard permits the use of either the retrospective or cumulative effect transition method. The Company is evaluating the effect that ASU 2014-09 will have on its consolidated financial statements and related disclosures. The Company has not yet selected a transition method nor has it determined the effect of the standard on its ongoing financial reporting.

This discussion and analysis of our financial condition and results of operations are based upon our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”). The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenue, expenses and related disclosures. We base our estimates on historical results which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. We evaluate these estimates on an ongoing basis. Actual results may differ from these estimates under different assumptions or conditions.

We have accounting policies that involve estimates such as the allowance for doubtful accounts, revenue reserves, useful lives of long-lived assets, fair value of our common and preferred units issued as compensation, accruals for estimated tax and legal liabilities, accruals for exit activities associated with real estate leases, accruals for customer disputes and valuation allowance for deferred tax assets. We have identified the policies below, which require the most significant judgments and estimates to be made in the preparation of our consolidated financial statements, as critical to our business operations and an understanding of our results of operations.

We recognize revenue derived from leasing fiber optic telecommunications infrastructure and the provision of telecommunications and colocation services when the service has been provided and when there is persuasive evidence of an arrangement, the fee is fixed or determinable and collection of the receivable is reasonably assured. Taxes collected from customers and remitted to government authorities are excluded from revenue.

We often bill customers for upfront charges, which are non-refundable. These charges relate to down payments or prepayments for future services and are influenced by various business factors including how we and the customer agree to structure the payment terms. If the upfront payment made by a customer provides no benefit to the customer beyond the contract term, the upfront charge is deferred and recognized as revenue ratably over the contract term. If the upfront payment provides benefit to the customer beyond the contract term, the charge is recognized as revenue over the estimated life of the customer relationship.

Revenue attributable to leases of dark fiber pursuant to IRUs is accounted for in the same manner as the accounting treatment for sales of real estate with property improvements or integral equipment. This accounting treatment typically results in the deferral of revenue for the cash that has been received and the recognition of revenue ratably over the term of the agreement (generally up to 20 years).

Revenue is recognized at the amount expected to be realized, which includes billing and service adjustments. During each reporting period, we make estimates for potential future sales credits to be issued in

respect of current revenue related to service interruptions and customer disputes, which are recorded as a reduction in revenue. We analyze historical credit activity when evaluating our credit reserve requirements. We reserve for known service interruptions as incurred. We review customer disputes and reserve against those we believe to be valid claims. The determination of the customer dispute credit reserve involves significant judgment, estimations and assumptions.

We defer recognition of revenue until cash is collected on certain components of revenue, principally contract termination charges and late fees.

We estimate the ability to collect our receivables by performing ongoing credit evaluations of our customers’ financial condition, and provide an allowance for doubtful accounts based on expected collection of our receivables. Our estimates are based on assumptions and other considerations, including payment history, credit ratings, customer financial performance, industry financial performance and aging analysis.

We account for our stock-based compensation in accordance with the provisions of ASC 718—Compensation: Stock Compensation, which requires stock compensation to be recorded as either liability or equity awards based on the terms of the grant agreement.

The CII common units granted to employees were considered to be stock-based compensation with terms that required the awards to be classified as liabilities due to cash settlement features. Prior to Holdings’ initial public offering, we adjusted the value of the vested portion of our common unit liability awards to their fair value at the end of each reporting period. We used a third party valuation firm to assist in the valuation of the CII common units at each reporting period. In developing a value for the common units, a two-step valuation approach was used. In the first step, we estimated the value of our equity through an analysis of valuations associated with various future potential liquidity scenarios. The second step involved allocating these values across our capital structure.

We allocated value to each class of common units using the Probability Weighted Expected Return Method (“PWERM”). The unit value was based on a probability-weighted present value of expected future proceeds to our shareholders, considering each potential liquidity scenario available to us as well as preferential rights of each security. The potential scenarios that we considered within the PWERM framework were remaining a private company with the same ownership, a sale or merger, and an initial public offering. The PWERM utilized a variety of assumptions regarding the likelihood of a certain scenario occurring, if the scenario involved a transaction, the potential timing of such an event, and the potential valuation that each scenario might yield.

Based on these scenarios, management calculated the probability-weighted expected return to all of the equity holders. The resulting enterprise valuation was then allocated across our capital structure. Upon a liquidation of CII, or upon a non-liquidating distribution, the holders of common units would share in the proceeds after the CII preferred unit holders received their unreturned capital contributions and their priority return (6% per annum). After the preferred unreturned capital contributions and the priority return were satisfied, the remaining proceeds were allocated on a scale ranging from 85% to the Class A preferred unit holders and 15% to the common unit holders to 80% to the preferred unit holders and 20% to the common unit holders depending upon the return multiple to the preferred unit holders, also known as the waterfall allocation.

The value attributable to each class of shares was then discounted in order to account for the lack of marketability of the units. In determining the appropriate lack of marketability discount, we evaluated both empirical and theoretical approaches to arrive at a composite range that we believed indicated a reasonable spectrum of discounts for each of the valuation techniques utilized. The empirical methods we evaluated relied

on datasets procured from observed transactions in equity interests in the public domain that were perceived to incorporate pricing information related to the marketability (or lack thereof) of the equity interest itself. These empirical methods included initial public offering studies and restricted stock studies. Theoretical models utilized in our analysis formed the primary basis for the discount for lack of marketability, and included the Finnerty Average-Strike Put, the Asian Protective Put and the Black-Scholes-Merton Protective Put.

In connection with Holdings’ initial public offering and the related amendment to the CII operating agreement, there was a deemed modification to the stock compensation arrangements with our current and former employees and directors. As a result, previously issued common units, which were historically accounted for as liability awards, became classified as equity awards. Prior to reclassifying our common unit liability to equity, we re-measured the fair value of the CII common units factoring in the change in fair value resulting from the passage of time and the change in fair value caused by the modification. The fair value of these previously vested common units was estimated to be $490.2 million on the modification date, and this amount is reflected in our consolidated statement of Member’s equity as an increase to member’s interest during the year ended June 30, 2015. The unrecognized compensation associated with unvested CII common units was $70.2 million as of June 30, 2015, which will be recognized ratably over the remaining vesting period of the outstanding common units through May 15, 2017.

On October 9, 2014, we and CII’s board of managers approved a non-liquidating distribution by CII of shares of Holdings’ common stock held by CII to holders of CII vested common units. Holders of vested CII common units received shares of Holdings’ common stock as a distribution in respect of the value of their underlying vested CII common units. Employees with unvested CII common units will continue to receive monthly distributions from CII of our common stock as they vest under the original terms of the CII common unit grant agreements. CII may be required to distribute additional shares of Holdings’ common stock to CII common unit holders on a quarterly basis through June 30, 2016 based on our stock price performance, subject to the existing vesting provisions of the CII common units. The shares to be distributed to the common unit holders are based on a pre-existing distribution mechanism, whose primary input is our stock price at each subsequent measurement date. Any remaining shares of common stock owned by CII will be distributed to the existing CII preferred unit holders.

The valuation of the CII common units as of the date of Holdings’ initial public offering was determined based on a Monte Carlo simulation. The Monte Carlo valuation analysis attempts to approximate the probability of certain outcomes by running multiple trial runs, called simulations, using random variables to generate potential future stock prices. This valuation technique was used to estimate the fair value associated with future distributions of our common stock to CII common unit holders. The Monte Carlo simulation first projects the number of shares to be distributed by CII to the common unit holders at each subsequent measurement date based on stock price projections under each simulation. Shares attributable to unvested CII common units are subject to the existing vesting provisions of the CII common unit awards. The estimated future value of shares scheduled to be distributed by CII based on vesting provisions are calculated under each independent simulation. The present value of the number of shares of common stock to be distributed to common unit holders under each simulation is then computed, and the average of each simulation is the fair value of our common stock to be distributed by CII to the common unit holders. This value was then adjusted for prior non-liquidating distributions made by us to derive a value for CII common units by class and on a per unit basis. These values were used to calculate the fair value of outstanding CII common units as of the IPO date. Various inputs and assumptions were utilized in the valuation method, including forfeiture behavior, vesting provisions, holding restrictions, peer companies’ historical volatility, and an appropriate risk-free rate.

In October 2014, Holdings’ Board of Directors adopted the 2014 Performance Compensation Incentive Plan (“PCIP”). The PCIP includes incentive cash compensation and equity (in the form of Holdings’ restricted stock units or “RSUs”). Grants of RSUs under the PCIP plan are made quarterly for all participants. The PCIP went into effect on October 16, 2014.

Under Part A of the PCIP, most full-time employees, including our executives, are eligible to earn quarterly awards of RSUs. Each participant in Part A of the PCIP has a target RSU annual award value, which will be allocated each fiscal quarter. The number of Part A RSUs granted will be calculated based on the final award value determined by the Compensation Committee divided by the average closing price of our common stock over the last ten trading days of the respective performance quarter. Part A RSUs granted to participants cliff vest based upon continued employment through one year after the last day of the quarter in which the Part A RSU grant is made, and at that time will be exchanged for an equal number of shares in Holdings’ common stock.

Each quarterly Part A award is recorded as a liability as of the end of the respective measurement quarter, as the awards represent an obligation denominated in a fixed dollar amount to be settled in a variable number of shares during the subsequent quarter. Upon the issuance of the RSUs, the liability is re-measured, representing the vested portion of the fair value of the actual number of RSUs issued, and the liability is then reclassified to member’s interest. The remaining unvested value is expensed through the respective vesting date.

Under Part B of the PCIP, participants, who include members of our senior management team, are awarded quarterly grants of RSUs. The number of Part B RSUs earned by the participants cliff vest, if at all, based upon (i) Holdings’ stock price performance over a performance period of one year with the starting price being the average closing price over the last ten trading days of the quarter immediately prior to the grant and the average closing price over the last ten trading days of the measurement period and (ii) continued employment through one year after the last day of the quarter preceding the grant date of the Part B RSU. The existence of a vesting provision that is associated with the performance of our stock price is a market condition, which affects the determination of the grant date fair value. Upon vesting, RSUs convert to shares of Holdings’ common stock.

The grant date fair value of Part B awards issued during a given period are expensed over the performance period. The grant date fair value is estimated utilizing a Monte Carlo simulation, which uses randomly generated stock-price paths through a Geometric Brownian Motion stock price simulation. This simulation provides a stochastic projection of the ten-day average closing stock price ending on the vesting date (i.e., end of performance period), the total stock price performance over the performance period, and the number of common shares to be issued at the vesting date. Various assumptions are utilized in the valuation method, including the target stock price performance ranges and respective share payout percentages, our historical stock price performance and volatility, peer companies’ historical volatility and an appropriate risk-free rate. The aggregate future value of the grant under each simulation is calculated using the estimated per share value of the common stock at the end of the restriction period multiplied by the number of common shares projected to be granted at the vesting date. The present value of the aggregate grant is then calculated under each simulation resulting in a distribution of potential present values. The average of this present value distribution equals the fair value of the grant.

We record property and equipment acquired in connection with a business combination at their estimated fair values on the acquisition date. See “—Critical Accounting Policies and Estimates: Acquisitions—Purchase Price Allocation.” Purchases of property and equipment are stated at cost, net of depreciation. Major improvements are capitalized, while expenditures for repairs and maintenance are expensed when incurred. Costs incurred prior to a capital project’s completion are reflected as construction-in-progress and are part of network infrastructure assets. Depreciation begins once the property and equipment is available and ready for use. Certain internal direct labor costs of constructing or installing property and equipment are capitalized. Capitalized direct

labor reflects a portion of the salary and benefits of certain field engineers and other employees that are directly related to the construction and installation of network infrastructure assets. We have contracted with third party contractors for the construction and installation of the majority of our fiber network. Depreciation and amortization is provided on a straight-line basis over the estimated useful lives of the assets, with the exception of leasehold improvements, which are amortized over the lesser of the estimated useful lives or the term of the lease.

We perform periodic internal reviews to estimate useful lives of our property and equipment. Due to rapid changes in technology and the competitive environment, selecting the estimated economic life of telecommunications property and equipment requires a significant amount of judgment. Our internal reviews take into account input from our network services personnel regarding actual usage, physical wear and tear, replacement history, and assumptions regarding the benefits and costs of implementing new technology that factor in the need to meet our financial objectives.

When property and equipment is retired or otherwise disposed of, the cost and accumulated depreciation is removed from the accounts, and resulting gains or losses are reflected in operating income.

From time to time, we are required to replace or re-route existing fiber due to structural changes such as construction and highway expansions, which is defined as a “relocation.” In such instances, we fully depreciate the remaining carrying value of network infrastructure removed or rendered unusable, and capitalize the new fiber and associated construction costs of the relocation placed into service. To the extent that the relocation does not require the replacement of components of our network, and only involves the act of moving our existing network infrastructure, as-is, to another location, the related costs are expensed as incurred.

Interest costs are capitalized for all assets that require a period of time to get them ready for their intended use. This policy is based on the premise that the historical cost of acquiring an asset should include all costs necessarily incurred to bring it to the condition and location necessary for its intended use. In principle, the cost incurred in financing expenditures for an asset during a required construction or development period is itself a part of the asset’s historical acquisition cost. The amount of interest costs capitalized for qualifying assets is determined based on the portion of the interest cost incurred during the assets’ acquisition periods that theoretically could have been avoided if expenditures for the assets had not been made. The amount of interest capitalized in an accounting period is calculated by applying the capitalization rate to the average amount of accumulated expenditures for the asset during the period. The capitalization rates used to determine the value of interest capitalized in an accounting period is based on our weighted average effective interest rate for outstanding debt obligations during the respective accounting period.

We periodically evaluate the recoverability of our long-lived assets and evaluate such assets for impairment whenever events or circumstances indicate that the carrying amount of such assets may not be recoverable.

Impairment is determined to exist if the estimated future undiscounted cash flows are less than the carrying value of such assets. We consider various factors to determine if an impairment test is necessary. The factors include: consideration of the overall economic climate, technological advances with respect to equipment, our strategy, and capital planning. Since our inception, no event has occurred nor has there been a change in the business environment that would trigger an impairment test for our property and equipment assets.

Deferred tax assets arise from a variety of sources, the most significant being: tax losses that can be carried forward to be utilized against taxable income in future years; and expenses recognized in our income statement but disallowed in our tax return until the associated cash flow occurs.

We record a valuation allowance to reduce our deferred tax assets to the amount that is expected to be recognized. The amount of deferred tax assets recorded on our consolidated balance sheets is influenced by management’s assessment of our future taxable income with regard to relevant business plan forecasts, the reversal of deferred tax balances, and reasonable tax planning strategies. At each balance sheet date, existing assessments are reviewed and, if necessary, revised to reflect changed circumstances. In a situation where recent losses have been incurred, the relevant accounting standards require convincing evidence that there will be sufficient future taxable income.

In connection with several of our acquisitions, we have acquired significant net operating loss carry forwards (“NOLs”). The Tax Reform Act of 1986 contains provisions that limit the utilization of NOLs if there has been an “ownership change” as described in Section 382 of the Internal Revenue Code.

Upon acquiring a company that has NOLs, we prepare an assessment to determine if we have a legal right to use the acquired NOLs. In performing this assessment we follow the regulations within the Internal Revenue Code Section 382: Net Operating Loss Carryovers Following Changes in Ownership. Any disallowed NOLs acquired are written-off in purchase accounting.

A valuation allowance is required for deferred tax assets if, based on available evidence, it is more-likely-than-not that all or some portion of the asset will not be realized due to the inability to generate sufficient taxable income in the period and/or of the character necessary to utilize the benefit of the deferred tax asset. When evaluating whether it is more-likely-than-not that all or some portion of the deferred tax asset will not be realized, all available evidence, both positive and negative, that may affect the realizability of deferred tax assets is identified and considered in determining the appropriate amount of the valuation allowance. We continue to monitor our financial performance and other evidence each quarter to determine the appropriateness of our valuation allowance. If we are unable to meet our taxable income forecasts in future periods we may change our conclusion about the appropriateness of the valuation allowance which could create a substantial income tax expense in our consolidated statement of operations in the period such change occurs.

As of June 30, 2015, we had a cumulative federal (U.S.) NOL carry forward balance of $1,115.0 million. During the year ending June 30, 2015, we utilized $95.9 million of NOL carry forwards that were available to offset future taxable income. Our NOL carry forwards, if not utilized to reduce taxable income in future periods, will expire in various amounts beginning in 2020 and ending in 2032. As a result of Internal Revenue Service regulations, we are currently limited to utilizing a maximum of $485.9 million of acquired NOL carry forwards during Fiscal 2015; however, to the extent that we do not utilize $485.9 million of our acquired NOL carry forwards during a fiscal year, the difference between the $485.9 million maximum usage and the actual NOLs usage is carried over to the next calendar year. Of our $1,115.0 million NOL carry forwards balance, $927.0 million of these NOL carry forwards were acquired in acquisitions. The deferred tax assets recognized at June 30, 2015 have been based on future profitability assumptions over a five-year horizon.

The analysis of our ability to utilize our NOL balance is based on our forecasted taxable income. The forecasted assumptions approximate our best estimates, including market growth rates, future pricing, market

acceptance of our products and services, future expected capital investments, and discount rates. Although our forecasted income includes increased taxable earnings in future periods, flat earnings over the period in which our NOL carry forwards are available would result in full utilization of our current unreserved NOL carry forwards.

We review goodwill and indefinite-lived intangible assets for impairment at least annually in April, or more frequently if a triggering event occurs between impairment testing dates.

Intangible assets arising from business combinations, such as acquired customer contracts and relationships (collectively “customer relationships”), are initially recorded at fair value. We amortize customer relationships primarily over an estimated life of ten to twenty years using the straight-line method, as this method approximates the timing in which we expect to receive the benefit from the acquired customer relationship assets. Goodwill represents the excess of the purchase price over the fair value of the net identifiable assets acquired in a business combination.

Our impairment assessment begins with a qualitative assessment to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying value. The qualitative assessment includes comparing the overall financial performance of the reporting units against the planned results used in the last quantitative goodwill impairment test. Additionally, each reporting unit’s fair value is assessed in light of certain events and circumstances, including macroeconomic conditions, industry and market considerations, cost factors, and other relevant entity- and reporting unit-specific events. If it is determined under the qualitative assessment that it is more likely than not that the fair value of a reporting unit is less than its carrying value, then a two-step quantitative impairment test is performed. Under the first step, the estimated fair value of the reporting unit is compared with its carrying value (including goodwill). If the fair value of the reporting unit exceeds its carrying value, step two does not need to be performed. If the estimated fair value of the reporting unit is less than its carrying value, an indication of goodwill impairment exists for the reporting unit and the enterprise must perform step two of the impairment test (measurement). Under step two, an impairment loss is recognized for any excess of the carrying amount of the reporting unit’s goodwill over the implied fair value of that goodwill. The implied fair value of goodwill is determined by allocating the fair value of the reporting unit in a manner similar to a purchase price allocation in acquisition accounting. The residual fair value after this allocation is the implied fair value of the reporting unit goodwill. Fair value of the reporting unit under the two-step assessment is determined using a discounted cash flow analysis. The selection and assessment of qualitative factors used to determine whether it is more likely than not that the fair value of a reporting unit exceeds the carrying value involves significant judgments and estimates.

Our impairment assessment for indefinite-lived intangible assets involves comparing the estimated fair value of indefinite-lived intangible assets to their respective carrying values. To the extent the carrying value of indefinite-lived intangible assets exceeds the fair value, we will recognize an impairment loss for the difference.

Intangible assets with finite useful lives are amortized over their respective estimated useful lives and reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. We recorded no impairment charges for goodwill or intangibles during the years ended June 30, 2015, 2014, or 2013.

We apply the acquisition method of accounting to account for business combinations. The cost of an acquisition is measured as the aggregate of the fair values at the date of exchange of the assets given, liabilities incurred, and equity instruments issued. Identifiable assets, liabilities, and contingent liabilities acquired or assumed are measured separately at their fair value as of the acquisition date. The excess of the cost of the

acquisition over our interest in the fair value of the identifiable net assets acquired is recorded as goodwill. If our interest in the fair value of the identifiable net assets acquired in a business combination exceeds the cost of the acquisition, a gain is recognized in earnings on the acquisition date only after we have reassessed whether we have correctly identified all of the assets acquired and all of the liabilities assumed.

For certain of our larger acquisitions, we engage outside appraisal firms to assist in the fair value determination of identifiable intangible assets such as customer relationships, tradenames, property and equipment and any other significant assets or liabilities. We adjust the preliminary purchase price allocation, as necessary, after the acquisition closing date through the end of the measurement period (up to one year) as we finalize valuations for the assets acquired and liabilities assumed.

The determination and allocation of fair values to the identifiable assets acquired and liabilities assumed is based on various assumptions and valuation methodologies requiring considerable management judgment. The most significant variables in these valuations are discount rates, terminal values, the number of years on which to base the cash flow projections, and the assumptions and estimates used to determine cash inflows and outflows or other valuation techniques (such as replacement cost). We determine which discount rates to use based on the risk inherent in the related activity’s current business model and industry comparisons. Terminal values are based on the expected life of products, forecasted life cycle and forecasted cash flows over that period. Although we believe that the assumptions applied in the determination are reasonable based on information available at the date of acquisition, actual results may differ from the estimated or forecasted amounts and the difference could be material.

Our exposure to market risk consists of changes in interest rates from time to time and market risk arising from changes in foreign currency exchange rates that could impact our cash flows and earnings.

As of June 30, 2015, we had outstanding $350.0 million 2025 Notes, $1,430.0 million 2023 Notes and $325.6 million 2020 Unsecured Notes, a balance of $1,646.8 million on our Term Loan Facility, and $32.7 million of capital lease obligations. As of June 30, 2015, we had $440.8 million available for borrowing under our Revolver.

On April 17, 2015, we entered into a Seventh Amendment to our Credit Agreement governing our Term Loan Facility and the Revolver which increased our borrowing capacity on the Revolver from $250.0 million to $450.0 million.

Based on current market interest rates for debt of similar terms and average maturities and based on recent transactions, we estimate the fair value of our Existing Notes to be $2,109.3 million as of June 30, 2015. Our 2025 Notes, 2023 Notes and 2020 Unsecured Notes accrue interest at fixed rates of 6.375%, 6.00% and 10.125%, respectively.

Both our Revolver and our Term Loan Facility accrue interest at floating rates subject to certain conditions. As of June 30, 2015, the applicable interest rate on our Revolver was 3.0% and the rate on our Term Loan Facility was 3.75%. A hypothetical increase in the applicable interest rate on our Term Loan Facility of one percentage point would increase our annual interest expense by only 0.283% or $4.7 million, which is limited as a result of the applicable interest rate as of June 30, 2015 being below the Credit Agreement’s 1.0% LIBOR floor. A hypothetical increase of one percentage point above the LIBOR floor would increase the Company’s annual interest expense by approximately $16.5 million before considering the offsetting effects of our interest rate swaps.

In August 2012, we entered into interest rate swap agreements with an aggregate notional value of $750.0 million and a maturity date of June 30, 2017. The contract states that we pay a 1.67% fixed rate of interest for the term of the agreement, beginning June 30, 2013. The counterparties pay to us the greater of actual LIBOR or 1.25%. We entered into the swap arrangements to reduce the risk of increased interest costs associated with potential future increases in LIBOR rates. A hypothetical increase in LIBOR rates of 100 basis points would increase the fair value of our interest rate swaps by approximately $7.3 million.

We are exposed to the risk of changes in interest rates if it is necessary to seek additional funding to support the expansion of our business and to support acquisitions. The interest rate that we may be able to obtain on future debt financings will be dependent on market conditions.

We have exposure to market risk arising from foreign currency exchange rates. During the year ended June 30, 2015, our foreign activities accounted for 11% of our consolidated revenue. We monitor foreign markets and our commitments in such markets to assess currency and other risks. Currently, fluctuations in foreign exchange rates do not pose a material risk, a 1% increase in foreign exchange rates would change consolidated revenue by approximately $1.5 million. To date, we have not entered into any hedging arrangement designed to limit exposure to foreign currencies. Because of our more recent European expansion related to the Geo and Neo acquisitions, our level of foreign activities is expected to increase and if it does, we may determine that such hedging arrangements would be appropriate and will consider such arrangements to minimize our exposure to foreign exchange risk.

We are a large and fast growing provider of bandwidth infrastructure in the United States and Europe, and a wholly-owned subsidiary of Holdings. Our products and services enable mission-critical, high-bandwidth applications, such as cloud-based computing, video, mobile, social media, machine-to-machine connectivity, and other bandwidth-intensive applications. Key products include leased dark fiber, fiber to cellular towers and small cell sites, dedicated wavelength connections, Ethernet and IP connectivity and other high-bandwidth offerings. We provide our services over a unique set of dense metro, regional, and long-haul fiber networks and through our interconnect-oriented datacenter facilities. Our fiber networks and datacenter facilities are critical components of the overall physical network architecture of the Internet and private networks. Our customer base includes some of the largest and most sophisticated consumers of bandwidth infrastructure services, such as wireless service providers; telecommunications service providers; financial services companies; social networking, media, and web content companies; education, research, and healthcare institutions; and governmental agencies. We typically provide our bandwidth infrastructure services for a fixed monthly recurring fee under contracts that vary between one and twenty years in length. We operate our business with a unique focus on capital allocation and financial performance with the ultimate goal of maximizing equity value for the Holdings stockholders. Our core values center on partnership, alignment, and transparency with our three primary constituent groups—employees, customers, and stockholders.

We were founded in 2007 with the investment thesis of building a bandwidth infrastructure platform to take advantage of the favorable Internet, data, and wireless growth trends driving the on-going demand for bandwidth infrastructure, and to be an active participant in the consolidation of the industry. The growth of cloud-based computing, video, mobile and social media applications, machine-to-machine connectivity, and other bandwidth-intensive applications continues to drive rapidly increasing consumption of bandwidth on a global basis Cisco estimates that mobile data traffic will grow at a compound annual growth rate of 57% from 2014 to 2019 and that IP traffic will grow at a compound annual growth rate of 21% from 2013 to 2018. As an early believer in the enduring nature of these trends, we assembled our asset base and built a business model specifically to provide high-bandwidth connectivity to customers whose businesses depend most on the continuous and growing demand for bandwidth. As a core tenet of our strategy for capitalizing on these industry trends, we have been a leading industry consolidator and have acquired 34 bandwidth infrastructure businesses and assets to date. Our owned, secure, and redundant fiber network and datacenters serve as the foundation for our bandwidth solutions and allow us to offer customers both physical infrastructure and cloud and connectivity services. We believe the continuously growing demand for stable and secure bandwidth from service providers, enterprises and consumers, combined with our unique and dense metro, regional, and long-haul networks, position us as a mission-critical infrastructure supplier to the largest users of bandwidth.

Our network footprint includes both large and small metro geographies, the extended suburban regions of many cities, and the large rural, national and international links that connect our metro networks. We believe that our network assets would be difficult to replicate given the geographic reach, network density, and capital investment required. Our fiber networks span over 85,500 route miles and 6,700,000 fiber miles (representing an average of 78 fibers per route), served 320 geographic markets in the United States and Europe, and connect to approximately 18,000 buildings, including 5,000 cellular towers and 863 datacenters. We own fiber networks in over 300 metro markets, including large metro areas, such as New York, Chicago, San Francisco, Paris, and London, as well as smaller metro areas, such as Allentown, Pennsylvania, Fargo, North Dakota, and Spokane, Washington. Our networks allow us to provide our high-bandwidth infrastructure services to our customers over redundant fiber facilities between key customer locations. We believe our ownership and the location and density of our expansive network footprint allow us to more competitively service our target customers’ bandwidth infrastructure needs at the local, regional, national, and international level relative to other regional bandwidth infrastructure service providers or long-haul carriers. We also provide our network-neutral colocation and interconnection services utilizing our own datacenters located within major carrier hotels and other strategic buildings in 45 locations throughout the United States and France and operate more than 520,000 square feet of billable colocation space.

The density and geographic reach of our network footprint allow us to provide tailored bandwidth infrastructure solutions on our own network (“on-net”) that address the current and future bandwidth needs of our customers. Our dense metro and regional networks have high fiber counts that enable us to provide both our physical infrastructure services (e.g., dark fiber) and our cloud and connectivity services (e.g., wavelengths and Ethernet). Our networks are deep and scalable, meaning we have spare fiber, conduit access rights and/or rights of way rights that allow us to continue to add capacity to our network as our existing and new customers’ demand for our services increases. In addition, many of our core network technologies provide capacity through which we can continue to add wavelengths to our network without consuming additional fiber. We also believe the density and diversity of our networks provide a strong and growing competitive barrier to protect our existing revenue base. We believe our networks provide significant opportunity to organically connect to new customer locations, datacenters, towers, or small cell locations to help us achieve an attractive return on our capital deployed. Since our founding, we have assembled a large portfolio of fiber networks and colocation assets through both acquisitions and customer demand-driven investments in property and equipment. From our inception to date, we have completed acquisitions with an aggregate purchase consideration, net of cash acquired, totaling approximately $4.6 billion. For the period from July 1, 2012 through June 30, 2015, we also invested over $1.2 billion in capital expenditures, exclusive of acquisitions and stimulus grant reimbursements, primarily to expand the reach and capacity of our networks. As of June 30, 2015, our total debt (including capital lease obligations and before any unamortized discounts, premiums and debt issuance costs) was $3,785.1 million and was primarily incurred in connection with acquisitions.

Our business model focuses on providing on-net bandwidth infrastructure solutions to our customers, which results in what we refer to as “infrastructure economics.” Infrastructure economics are characterized by attractive revenue visibility, strong margins coupled with operating leverage for new revenue, success-based capital investments with low maintenance capital needs, and the ability to generate significant cash flow over time. Our capital expenditure investments are predominantly success-based, meaning that before we commit resources to expand our network, we have a signed customer contract that will provide us with an attractive return on the required capital. After committing capital to connect additional customer sites, our goal is to sell additional high-bandwidth connectivity on these new routes at a relatively low incremental cost, which further enhances the return we extract from our asset base. Finally, the combination of our scale and infrastructure economics results in the ability to generate meaningful free cash flow over time.

Our management is intensely focused on creating equity value for the Holdings stockholders. Our equity value creation philosophy includes regular and rigorous financial and operational measurement, financial transparency (both internally and externally), and clear alignment of interests among employees, management, and stockholders. Our real-time measurement and reporting system serves as the foundation for our decision making and our extensive financial and operational disclosure. We also believe in fostering an entrepreneurial culture that aligns the interests of our employees, management, and stockholders.

We are a Delaware limited liability company and wholly owned subsidiary of Holdings, a Delaware corporation, formed in 2007. As of June 30, 2015, we had 1,833 employees.

Our fiscal year ends June 30 each year and we refer to the fiscal year ended June 30, 2015 as “Fiscal 2015”, the fiscal year ended June 30, 2014 as “Fiscal 2014”, and the fiscal year ended June 30, 2013 as “Fiscal 2013”.

We are a bandwidth infrastructure provider, and our services are a critical component of the broader $2 trillion global communications industry. Bandwidth infrastructure, consisting primarily of fiber networks and interconnect-oriented colocation facilities, plays a fundamental role in the communications value chain, similar to other types of infrastructure such as datacenters and cellular towers. Bandwidth infrastructure assets are a critical resource, connecting datacenters, cellular towers, and other carrier and private networks to support the substantial growth in global data, voice and video consumption by both business and individual consumers.

Our industry has changed substantially over the past 16 years. The first phase of the bandwidth infrastructure industry occurred with the advent of the Internet and the ensuing dot com era in the late 1990s. This led to the first major wave of fiber network deployments as a number of companies of varying backgrounds invested billions of dollars in fiber network construction throughout the U.S. and Europe. These fiber network developers included companies with national and international plans (e.g., Level 3 Communications, Qwest Communications, Williams Communications) and more regional plans (e.g., 360networks, Progress Telecom, OnFiber). Following these network builds, many of the fiber companies struggled in the early 2000s due to the lack of sufficient demand for their high-bandwidth services. Bandwidth demand during this timeframe was limited by the fact that many bandwidth-intensive applications (e.g. streaming video, cloud, mobile broadband, big data analytics, etc.) were either not yet contemplated or still very early in their life cycle. Instead, the majority of traffic at the time was low-bandwidth services such as voice and dial-up modem connections. In addition, the similarity of the fiber routes deployed resulted in significant overcapacity and associated pricing pressure, leaving a “last mile” gap and heavy competition and overcapacity along these routes. These two primary factors combined to significantly limit the fiber network providers’ operating cash flows, resulting in the majority of these companies transitioning their business models, consolidating and/or seeking bankruptcy protection.

In the following years, a substantial expansion in computing power and bandwidth-intensive applications drove meaningful bandwidth traffic growth. This growth highlighted the need to address the “last mile” gap by bringing bandwidth capacity directly to both the consumer and business end user. The capacity and performance of the consumer last mile connection was primarily addressed by the expansion of cable networks and through mobile network development by wireless carriers (supported by cellular tower operators). The growing bandwidth demand of business end users was addressed by a number of focused fiber developers constructing new networks to directly connect to datacenters, cellular towers, government facilities, schools, hospitals and other locations with high-bandwidth needs. These fiber network companies were generally local or regional in nature, and were most often either survivors of the initial fiber development wave, subsidiaries of a utility parent, or owned by entrepreneurs. This period is also noted for increased financial discipline following the large speculative capital deployments of the dot com era. This is the timeframe and industry environment in which our Company was founded.

The acceleration in the development of bandwidth-intensive devices and applications has resulted in a significant need to further fill in the “last mile” gap, leading to substantial capital investments in fiber networks by bandwidth infrastructure providers. Bandwidth infrastructure service providers support applications such as high definition television broadcasting and video; online streaming video; cloud applications replacing in-house enterprise software platforms; and explosive mobile data consumption (Cisco found that, in 2013, global mobile data traffic grew 81% and was nearly 18 times the size of the entire global Internet in 2000). Companies whose services require large amounts of bandwidth and enterprises that consume large amounts of bandwidth are struggling to adapt to this rapidly evolving landscape, and the bandwidth infrastructure industry is growing in economic importance as it addresses this critical need. In addition to these demand trends, there has been significant consolidation amongst the bandwidth infrastructure services providers, validating a core tenet of the Company’s founding investment thesis. This has been most pronounced amongst fiber providers in the U.S., with over 60 transactions within the past 10 years (approximately half of which have been consummated by us), and to a lesser degree in Europe.

We view the participants in today’s communications industry in two distinct categories:

The proliferation of smart devices and mobile broadband, real-time streaming video, social networks, online gaming, machine-to-machine connectivity, big data analytics, and cloud computing will continue to drive substantial consumer and business demand for bandwidth. Cisco estimates that mobile data traffic will grow at a compound annual growth rate of 57% from 2014 to 2019 and that IP traffic will grow at a compound annual growth rate of 21% from 2013 to 2018. Additionally, according to Gartner, “4.9 billion connected things will be in use in 2015, up 30 percent from 2014, and will reach 25 billion by 2020. The Internet of Things (IoT) has become a powerful force for business transformation, and its disruptive impact will be felt across all industries and all areas of society.” (Gartner Press Release, “Gartner Says 4.9 Billion Connected ‘Things’ Will Be in Use in 2015,” November 11, 2014, http://www.gartner.com/newsroom/idl2905717).

Communications service providers develop and deliver value-added solutions that are tailored to mass market residential and enterprise customers whose needs continue to grow and evolve as bandwidth trends expand. Given this rapid growth and the complexity and cost of building and maintaining networks, communications service providers are increasingly looking to bandwidth infrastructure providers to augment the reach and performance of their own networks and support the delivery of the services their customers demand. As this dynamic continues, bandwidth infrastructure providers will become further entrenched as mission-critical partners to the communications service providers.

Similarly, end users such as private enterprises (e.g., media/content providers, financial institutions, and hospital systems) and public sector entities (e.g., governmental agencies and school districts) have experienced significant growth and change in the role that bandwidth plays within their organizations. As these needs continue to grow in both volume and criticality, end users will increasingly choose to directly procure bandwidth infrastructure services in order to gain more security, control and scale in their internal network operations. An example of this disintermediation is the trend of large school districts, adapting to e-education requirements, directly purchasing dark fiber as a replacement to more value-added solutions. We believe that, as these dynamics play out across all industries, the number of end users directly seeking bandwidth infrastructure services will continue to expand.

By focusing on the reach, density, and performance of their physical networks, bandwidth infrastructure providers can deliver customized services to communications service providers and end users more quickly and with superior economics than these users could otherwise self-provide. Whether providing fiber connectivity to a wireless provider’s towers to enable mobile broadband, supplying a national communications service provider with a metro fiber footprint in new markets, providing a lit bandwidth connection to multiple enterprise datacenters for an industrial company, providing interconnection capabilities to a hosting company within a datacenter, or solving for the next society-impacting innovation, bandwidth infrastructure providers will continue to invest in and expand their infrastructure assets to meet this growing demand.

Given the natural economies of scale, there has been significant consolidation among bandwidth infrastructure providers, particularly in the U.S. We believe this consolidation trend will continue in the U.S. and is beginning in Europe. Combined with the barriers to new entrants, we foresee a decreasing number of bandwidth infrastructure providers against a backdrop of continued strong demand for their services.

Our bandwidth infrastructure assets consist of our fiber networks, the optronic equipment used to provide our lit services over our fiber networks, and our datacenters where we provide colocation and interconnection services.

Our fiber network footprint includes both large and small metro geographies, the extended suburban regions of many cities, and the large rural, national and international fiber links that connect our metro networks. Our network represents a collection of assets that we believe is difficult to replicate. Our fiber networks span over 85,500 route miles and 6,700,000 fiber miles (representing an average of 78 fibers per route), serve approximately 320 geographic markets in the United States and Europe, and connect approximately 18,000 buildings, including approximately 5,000 cellular towers and 863 datacenters. Our networks allow us to provide our high-bandwidth infrastructure services to our customers over redundant fiber facilities between critical customer locations. We believe the expansiveness and density of our fiber network footprint allow us to more competitively service our target customers’ bandwidth infrastructure needs at the local, regional, national, and international level relative to other regional or long-haul bandwidth infrastructure service providers. Our fiber networks also have the following key attributes:

Metro Fiber Networks. We use our metro fiber networks to provide bandwidth infrastructure services within the metro markets that we serve. Our metro networks are most commonly used in the following two scenarios. First, to provide service between on-net buildings that are located in the same geographic market. Second, to connect our on-net buildings within a metro market to another metro market via our regional and/or long-haul networks. We continue to expand our metro fiber networks within the metro geography and into the surrounding suburban areas as we extend to additional buildings to meet new demand on a success basis. Success-based expansion means that before we commit resources to expand our network, we have a signed customer contract that will provide us with an attractive return on required capital. In many of our metro markets, we have high count fiber cables (sometimes as many as 864 fibers per cable) and in some cases multiple spare conduits on our metro fiber routes. On individual segments where our fiber capacity becomes highly utilized, we seek to augment that capacity also on a success basis.

Regional and Long-haul Fiber Networks. We use our regional fiber networks to provide bandwidth infrastructure services between the metro markets that we serve. Our regional and long-haul networks are most commonly used in the following three scenarios. First, to provide service between on-net buildings that are located in different large markets (for example, Chicago and New York). Second, to connect our on-net buildings in small and mid-sized markets back to major datacenters, wireless switching centers, and carrier hotels in larger markets (for example, between Lima, Ohio and Cleveland, Ohio). Third, occasionally our networks provide service between on-net buildings in two different small or mid-sized markets located on various parts of our regional networks (for example, between Sioux Falls, South Dakota and Alexandria, Minnesota). We seek to continue to add new segments and markets to our regional and long-haul networks on a success basis, supported by a customer contract. We have deployed current generation DWDM technologies across the majority of our regional and long-haul networks, allowing a current maximum scaling to four Terabytes (i.e. 4,000G) of bandwidth and the ability to add capacity as demand for bandwidth increases. We expect that as technology continues to advance, we will augment and invest in our regional and long-haul networks accordingly.

Fiber-to-the-Tower Networks. We operate fiber-to-the-tower networks across our fiber network footprint. We connect to approximately 5,000 cellular towers and have contracts with multiple national wireless carriers to build out to approximately 2,500 additional towers. These FTT networks provide our customers with bandwidth infrastructure services that offer significantly improved speed, scale, performance and service levels relative to legacy copper and microwave networks. Our FTT networks are scalable, which means that we can quickly and easily increase the amount of bandwidth that we provide to each of the towers as our customers’ wireless data networks grow. Our FTT markets are generally in areas where we already have dense fiber networks (either metro or regional), which affords us the ability to offer ring-protected mobile infrastructure services. We are increasingly providing dark fiber services on our FTT networks.

Through these fiber networks, we provide service to over approximately 18,000 on-net buildings and are continually making success-based capital investments to increase our on-net building footprint. On-net buildings are buildings that are directly connected via fiber to our long-haul, regional, metro, and FTT networks. Our customers generally purchase our bandwidth infrastructure services to transport their data, Internet, wireless and voice traffic between buildings directly connected to our network. The types of buildings connected to our network primarily consist of the following:

Many of our zColo datacenter facilities are located in some of the most important carrier hotels in the United States, including 60 Hudson Street and 111 8th Avenue in New York; 165 Halsey Street in Newark; 401 N. Broad Street in Philadelphia; 1 Summer Street in Boston; 1950 N. Stemmons Freeway and 2323 Bryan Street in Dallas; and 2001 6th Street in Seattle. zColo also has the exclusive right to operate and provide colocation and interconnection services in the Meet-Me Room at 60 Hudson Street. We also have colocation facilities located in Atlanta, Ashburn, Austin, Baltimore, Chicago, Cincinnati, Cleveland, Columbus, Denver, Las Vegas, Los Angeles, Memphis, Miami, Nashville, Phoenix, Pittsburgh, Minneapolis, Washington, D.C. and nine additional locations in France. All of our facilities are network-neutral, and have ample power to meet customer needs, backup power in the form of batteries and generators, air conditioning, modern fire suppression equipment, 24/7 security and equipment monitoring, and redundant cooling capabilities. We have long-term leases with the owners of each of the buildings where we provide colocation services. Our colocation facilities total more than 520,000 square feet of billable colocation space.

We have the necessary right-of-way agreements and other required rights, including state and federal government authorization, to allow us to maintain and expand our fiber networks that are located on private property and public rights-of-way, including utility poles. When we expand our network, we obtain the necessary construction permits, license agreements, permits and franchise agreements. Certain of these permits, licenses and franchises are for a limited duration. When we need to use private property, our strategy is to obtain rights-of-way under long-term contracts.

We provide two major types of products and services, which form the basis for two of our three operating segments: Physical Infrastructure and Cloud and Connectivity. Our Other segment includes Zayo Professional Services (“ZPS”), our professional services business that provides network and technical resources to our customers. Across our segments, we operate individual Strategic Product Groups. Each Strategic Product Group has financial accountability and decision-making authority, which promotes agility in the fast-moving markets we serve. Financial information for each of our operating segments and our domestic and foreign operations is contained in Note 16—Segment Reporting to our consolidated financial statements.

Our primary network operating center (“NOC”) is located in Tulsa, Oklahoma and provides 24 hour per day, 365 days per year monitoring and network surveillance. As part of our business continuity plan, our primary NOC is backed up by several regional operations centers located in Washington, D.C.; Allentown, Pennsylvania; and Butte, Montana. We continually monitor for and proactively respond to any events that negatively impact or interrupt the services that we provide to our customers. Our NOC also responds to customer network inquiries via standard customer trouble ticket procedures. Our NOC coordinates and notifies our customers of maintenance activities and is the organization responsible for ensuring that we meet our service level agreements.

Our Information Technology systems have been designed and built specifically for the needs of a focused bandwidth infrastructure provider primarily leveraging the salesforce.com platform. This platform was adopted at our inception and has been enhanced over time to integrate all of our acquired companies and increase functionality in every area.

Our current systems’ capability is mature, and we view our application functionality as a competitive advantage in our industry. Our system is differentiated from the typical telecom industry technology solution consisting of separate and loosely integrated sales force automation, customer relationship management, provisioning, mapping, inventory, financial, provisioning and other systems with multiple, sometimes conflicting databases.

We have also developed within our salesforce.com platform a proprietary capability we call Tranzact. Tranzact is a set of tools and processes designed to enhance the speed and simplicity of procuring bandwidth infrastructure services. We believe Tranzact will further increase our competitive advantage in delivering bandwidth infrastructure solutions.

We have a fully implemented business continuity and disaster recovery plan that provides near real-time data access from physically diverse datacenters (Dallas and Washington, D.C.). We further protect our data with off-site data storage practices.

Our business primarily engages in direct sales through our sales organization, consisting of 134 sales representatives as of June 30, 2015. Each of these sales representatives is part of an enterprise or carrier focused sales team led by a sales director whose team is responsible for meeting a quarterly bookings quota. The sales organization sells services across all our Strategic Product Groups. The sales representatives are directly supported by sales management, engineering, solutions engineering and marketing staff.

The sales organization is organized into direct sales channels that generally align around both region and customer. Each of these channels maintains dedicated sales and solutions engineering support resources. There are four direct sales channels in the United States who are geographically focused supporting regional carriers and medium to large enterprise customers, particularly in the healthcare, education, internet content, media and financial sectors. Within those channels there are dedicated teams focused on our national wireline and wireless customers across all geographies. Within Europe, there are direct outside sales channels focused on similar European-based customers.

In addition to the direct channels discussed above, an indirect sales channel manages our channel partner program with various high value telecom sales agents. Finally, we have developed a group of sales overlay teams to focus on leveraging our infrastructure assets for the benefit of specific industry verticals and geographies.

Our direct sales force is compensated through a unique system relative to typical industry practices. Sales staff are compensated through salary and incentive compensation, which is comprised of cash and equity. Incentive compensation is achieved based upon the net present value (“NPV”) of the contracted services sold, the incremental revenue related to contracted services sold and the effective management of churn related to the accounts they manage. We believe that this compensation system best aligns the interests of our salespeople, management and the Holdings stockholders. It also is an example of the financial philosophy and culture that we have developed since our inception.

Separate from the sales groups, we have a corporate marketing group that is responsible for our web presence, customer facing mapping tools, marketing campaigns, and public relations. The sales organization is further supported by product management teams that are organized into the Strategic Product Groups.

Our customers generally have a significant and growing need for the bandwidth infrastructure services that we provide. Our customer base consists of wireless service providers, carriers and other communication service providers, media and content companies (including cable and satellite video providers), and other bandwidth-intensive businesses in the education, healthcare, financial services, governmental and technology entities. Our

largest single customer, based on recurring revenue, accounted for approximately 6% of our revenue during the year ended June 30, 2015, and total revenues from our top ten customers accounted for approximately 27% of our revenue during the same period. These customers are multinational organizations with substantial liquidity and access to capital, and whose bandwidth needs are mission-critical to their own businesses and strategies. While these large customers generally have a finite set of master contracts with us, they procure a large volume of individual services with us, each of which has its own service detail and term.

The majority of our customers sign Master Service Agreements (“MSAs”) that contain standard terms and conditions including service level agreements, required response intervals, indemnification, default, force majeure, assignment and notification, limitation of liability, confidentiality and other key terms and conditions. Most MSAs also contain appendices that contain information that is specific to each of the services that we provide. The MSAs either have exhibits that contain service orders or, alternatively, terms for services ordered are set forth in a separate service order. Each service order sets forth the minimum contract duration, the monthly recurring charge, and the non-recurring charges.

In pursuit of our mission, our Business Strategy includes the following key elements:

We believe the following are among our core competitive strengths and enable us to differentiate ourselves in the markets we serve:

Given the requirement to own the underlying bandwidth infrastructure assets (e.g., fiber networks and datacenter facilities) in order to provide physical infrastructure services, the competitive environment tends to be less intensive for these products and the barriers to entry high. The degree of competition and parties in competition vary by physical infrastructure sub-service and by individual market and fiber route. The competitive situation by service is described as follows:

Dark Fiber. Competition in dark fiber services tends to be less intense than for lit bandwidth infrastructure services primarily because a provider must predominantly own and operate a high count fiber network covering a substantial portion of the geographical demand in order to compete for a customer’s business. The uniqueness, density and depth (i.e., high fiber count) of our metro, regional, and long-haul fiber networks is therefore a key differentiating factor. In addition, given that providing dark fiber services often includes some degree of network expansion, dark fiber providers must also have internal project management expertise and access to capital to execute on the expansion aspect of the business. Due to the custom nature of most dark fiber opportunities, many larger lit bandwidth infrastructure providers do not actively market dark fiber as a product, even if they own fiber networks in the desired geographies. As a result, competition is often more limited in the dark fiber services market and highly dependent on the local (even sub-market) supply and demand environment. Given this dynamic and the generally longer contractual term of dark fiber services, dark fiber pricing tends to be more inflationary in nature.

Specific dark fiber competitors vary significantly based on geography, and often a particular solution can be provided by only one to three carriers that have sufficient fiber in place in the desired area or route. These competitors tend to fall into two categories: first, privately owned regional bandwidth infrastructure providers with a similar degree of focus (e.g., Lightower and Sunesys) and second, single market dark fiber providers with market and fiber construction expertise (e.g., DQE Communications and Edison Carrier Solutions).

Mobile Infrastructure. Competition in mobile infrastructure services tends to mirror dark fiber services because of the need to own and operate an expansive and deep metro fiber network in order to compete. Given the frequent need to expand upon an existing fiber footprint in order to access additional cell towers and small cell locations, project management expertise and access to capital is also a key competitive factor. One additional criterion is that wireless carriers prefer to work with a more finite group of mobile infrastructure providers on either a metro or regional geographic basis. As a result, the competitive group tends to match that of dark fiber services, with the addition of two competitive groups. First, local cable providers and ILECs who will often break from their retail and small enterprise core focus to compete for FTT business, often as a result of legacy copper or coaxial-based services provided to these towers. Second, microwave backhaul providers who focus on more remote or rural towers that have lesser bandwidth needs that they can serve with less capital-intensive (and less bandwidth-capable) microwave solutions at a lower total cost. Examples of these additional mobile infrastructure competitors are Comcast, Time Warner Cable, CenturyLink, PEG Bandwidth, Conterra and TTMI.

Colocation. The market for our colocation and interconnection services is very competitive. We compete based on price, quality of service, network-neutrality, breadth of network connectivity options, type and quantity of customers in our datacenters, and location. We compete against both large, public colocation providers who have significant enterprise values, and privately-held, well-funded companies. Some of our competitors have longer-standing customer relationships and significantly greater access to capital, which may enable them to materially increase datacenter space, and therefore lower overall market pricing for such services. Several of our competitors have much larger colocation facilities in the markets where we operate. Others operate globally and are able to attract a customer base that values and requires global reach and scale.

These focused interconnection and colocation service providers include: Equinix, Inc., The Telx Group, Inc., Terremark Worldwide, Inc. (a Verizon Communications, Inc. subsidiary), Coresite, Savvis, Inc. (a CenturyLink, Inc. subsidiary), and Cologix. These companies offer similar services and operate in similar markets to us.

We believe that some of the key factors that influence our customers’ selection of us as their cloud and connectivity services provider are our ability to provide an on-net service that utilizes our fiber network on an end-to-end basis, the ability to more quickly implement a complex custom solution to meet customers’ needs, the price of the service provided, and the ongoing customer service provided.

Generally, price competition varies depending on the size and location of the market. We face direct price competition when there are other fiber-based carriers who have networks that serve the same customers and geographies that we do. The specific competitors vary significantly based on geography, and often a particular solution can be provided by only one to three carriers that have comparable fiber in place. Typically, these competitors are large, well-capitalized ILECs, such as AT&T Inc., CenturyLink, Inc., and Verizon Communications Inc., or are publicly traded communications service providers that provide bandwidth infrastructure, such as Level 3 Communications, Inc. or Cogent Communications. In certain geographies, privately-held companies such as Lightower and Southern Light, can also offer comparable fiber-based solutions. On occasion, the price for high-bandwidth infrastructure services is too high compared with the cost of lower-speed, copper-based telecom services. We believe that price competition will continue where our competitors have comparable existing fiber networks. Some of our competitors have long-standing customer relationships, very large enterprise values, and significant access to capital.

We do not own any significant intellectual property, nor do we spend a material amount on research and development. Our working capital requirements and expansion needs have been satisfied to date through equity contributions, debt issuances and cash provided by operating activities.

Our operations require that certain of our subsidiaries hold licenses, certificates, and/or other regulatory authorizations from the Federal Communications Commission (“FCC”), state Public Utilities Commissions (“PUCs”), European telecommunications regulators such as Ofcom and ARCEP and other foreign regulators, all of which we have obtained and maintain in the normal course of our business. The FCC, State PUCs and foreign regulators generally have the power to modify or terminate a carrier’s authority to provide regulated wireline services for failure to comply with certain federal, state and foreign laws and regulations, and may impose fines or other penalties for violations of the same. The State PUCs typically have similar powers with respect to the intrastate services that we provide under their jurisdiction. In addition, we are required to submit periodic reports to the FCC, State PUCs, and foreign regulators documenting interstate, intrastate and foreign revenue, among other data, for fee assessments and general regulatory governance, and in some states are required to file tariffs of our rates, terms, and conditions of service. In order to engage in certain transactions in these jurisdictions, including changes of control, the encumbrance of certain assets, the issuance of securities, the incurrence of indebtedness, the guarantee of indebtedness of other entities, including subsidiaries of ours, and the transfer of our assets, we are required to provide notice and/or obtain prior approval from certain of these governmental agencies. The construction of additions to our current fiber network is also subject to certain governmental permitting and licensing requirements.

In addition, our business is subject to various other regulations at the federal, state, local and international levels. These regulations affect the way we can conduct our business and our costs of doing so. However, we believe, based on our examination of such existing and potential new regulations being considered in ongoing FCC, State PUC and European and other foreign telecommunications proceedings, that such regulations will not have a significant impact on us.

Our principal properties are fiber optic networks and their component assets. We own a majority of the communications equipment required for operating the network and our business. As of June 30, 2015, we own or lease approximately 85,500 fiber route miles or 6,700,000 fiber miles. We provide colocation and interconnection services utilizing our own data centers located within major carrier hotels and other strategic buildings in 45 locations throughout the United States and France. We generally do not own the buildings where we provide our colocation and interconnection services; however, the zColo group managed approximately 520,000 square feet of billable colocation space.

We lease our corporate headquarters in Boulder, Colorado as well as regional offices and sales, administrative and other support offices. Our corporate headquarters located at 1805 29th Street, Suite 2050, Boulder, Colorado is approximately 30,000 square feet. We lease properties to locate the POPs necessary to operate our networks. Office and POP space is leased in the markets where we maintain our network and generally ranges from 100 to 5,000 square feet. Each of our business units utilize these facilities. The majority of our leases have renewal provisions at either fair market value or a stated escalation above the last year of the current term.

In the ordinary course of business, we are from time to time party to various litigation matters that we believe are incidental to the operation of our business. We record an appropriate provision when the occurrence of loss is probable and can be reasonably estimated. We cannot estimate with certainty our ultimate legal and financial liability with respect to any such pending litigation matters, and it is possible one or more of them could have a material adverse effect on us. However, we believe that the outcome of any such pending litigation matters will not have a material adverse effect upon our results of operations, our consolidated financial condition, or our liquidity.

The following is a summary of provisions relating to our material indebtedness other than the Notes. The following summary does not purport to be complete and is subject to, and qualified in its entirety by reference to, the provisions of the corresponding agreements, including the definitions of certain terms therein that are not otherwise defined in this prospectus.

In addition to the Notes, we currently have outstanding $325.6 million aggregate principal amount of 10.125% senior unsecured notes due 2020 (the “2020 Notes”).

Interest on the 2020 Notes is payable on January 1 and July 1 of each year. The 2020 Notes will mature on July 1, 2020. At any time on or after July 1, 2016, we may redeem the 2020 Notes, in whole or in part, at the applicable redemption prices set forth in the indenture governing the 2020 Notes (the “2020 Indenture”), plus accrued and unpaid interest. Before July 1, 2016, we may redeem the 2020 Notes, in whole or in part, at a redemption price equal to 100% of their principal amount, plus accrued and unpaid interest and a “make-whole” premium as set forth in the 2020 Indenture. In addition, the 2020 Indenture provided for redemption of up to 35% of the 2020 Notes before July 1, 2015, at a redemption price equal to 110.125% of their principal amount, plus accrued and unpaid interest, using the proceeds of certain equity offerings. Under this provision, we redeemed $174.4 million of the 2020 Notes on December 16, 2014, with a portion of the proceeds of Holdings’ initial public offering. The 2020 Indenture limits any increase in our secured indebtedness (other than certain forms of secured indebtedness expressly permitted under the indentures) to a pro forma secured debt ratio of 4.50 times the previous quarter’s annualized modified EBITDA (as defined in the 2020 Indenture), and limits our incurrence of additional indebtedness to a total indebtedness ratio of 5.25 times the previous quarter’s annualized modified EBITDA.

The 2020 Indenture also contains covenants that, among other things, restricts the ability of the Issuers to incur additional indebtedness and issue preferred stock, pay dividends or make other distributions with respect to any equity interests, make certain investments or other restricted payments, create liens, sell assets, incur restrictions on the ability of their restricted subsidiaries to pay dividends or make other payments to the Issuers, consolidate or merge with or into other companies or transfer all or substantially all of their assets, engage in transactions with affiliates, and enter into sale and leaseback transactions.

We have a $450 million Revolver and a $1,643 million Term Loan Facility, which are governed by the Credit Agreement. The Term Loan Facility bears interest per annum at a fixed rate of LIBOR plus 2.75% with a minimum LIBOR rate of 1.0%, and the Revolver, which was undrawn as of June 30, 2015, bears interest at LIBOR plus 2.75% (based on our current leverage ratio). Borrowings under the Term Loan Facility and Revolver are prepayable at any time prior to maturity (subject to advance notice) without penalty. The Term Loan Facility will mature in May 2021. The Revolver will mature at the earliest of (i) five years after the effective date of the Seventh Amendment, (ii) six months prior to the maturity date of the Term Loan Facility, subject to repayment or amendment thereof, and (iii) six months prior to the maturity date of the 2020 Unsecured Notes, subject to repayment or amendment thereof.

The Credit Agreement, as amended, removed the covenant requiring us to maintain a certain fixed-charge coverage ratio. Such covenant was replaced with a requirement, applicable only to the Revolver, to maintain a senior secured leverage ratio below 5.25:1.00 at any time when the aggregate principal amount of loans outstanding under the Revolver is greater than 35% of the commitments under the Revolver.

The Credit Agreement also requires the Company and its subsidiaries to comply with customary affirmative and negative covenants, including covenants restricting the ability of the Company and its subsidiaries, subject to

specified exceptions, to incur additional indebtedness, make additional guaranties, incur additional liens on assets, or dispose of assets, pay dividends, or make other distributions, voluntarily prepay certain other indebtedness, enter into transactions with affiliated persons, make investments and amend the terms of certain other indebtedness.

In this “Description of 2023 Notes,” the word “Issuers” refers collectively to Zayo Group, LLC and Zayo Capital, Inc., and the word “Company” refers solely to Zayo Group, LLC, and not to any of its subsidiaries. The definitions of certain other terms used in this description are set forth throughout the text or under “—Certain Definitions.”

On January 23, 2015, the Issuers completed a private offering of $700 million aggregate principal amount of 6.00% senior unsecured notes due 2023 (the “2023 Outstanding Notes”) under an indenture dated January 23, 2015 (the “2023 Indenture”) among the Issuers, the Guarantors and The Bank of New York Mellon Trust Company, N.A., as trustee (the “Trustee”). On March 9, 2015, the Issuers completed a private offering of an additional $730 million aggregate principal amount of the 2023 Outstanding Notes under the 2023 Indenture, bringing the total aggregate principal amount of 2023 Outstanding Notes to $1.43 billion. The 2023 Outstanding Notes were issued in a private transaction that was not subject to the registration requirements of the Securities Act and are referred to collectively herein as the “Outstanding Notes.”

The Issuers will issue, in exchange for the 2023 Outstanding Notes, up to $1.43 billion aggregate principal amount of 6.00% senior unsecured notes due 2023 (the “2023 Exchange Notes”).

Except as otherwise indicated below, the following summary applies to both the 2023 Exchange Notes and the 2023 Outstanding Notes. As used in this “Description of 2023 Notes,” the term “2023 Notes” means both the 2023 Exchange Notes and the 2023 Outstanding Notes, unless otherwise indicated. The terms of the Notes will include those stated in the Indentures and those made part of the Indentures by reference to the Trust Indenture Act of 1939, as amended (the “TIA”).

The terms of the 2023 Exchange Notes and the 2023 Outstanding Notes are substantially identical, except that the 2023 Exchange Notes:

The following description is a summary of the material terms of the 2023 Indenture. It does not, however, restate the 2023 Indenture in its entirety. You should read the 2023 Indenture because it contains additional information and because the 2023 Indenture, and not this description, define your rights as a holder of the 2023 Notes. A copy of the 2023 Indenture may be obtained by requesting it from the Company.

Brief Description of the Structure and Ranking of the 2023 Notes and the 2023 Note Guarantees

As of June 30, 2015 and after excluding intercompany balances and intercompany guarantees:

As of the date of this prospectus, none of the Company’s Foreign Subsidiaries and Zayo Capital, Inc., the co-issuer, guarantee the 2023 Notes. For the year ended June 30, 2015, the non-guarantor Subsidiaries of the Company (other than Zayo Capital, Inc.) generated 12% of the Company’s consolidated net revenue and 10% of the Company’s consolidated Adjusted EBITDA. In addition, as of June 30, 2015, these non-guarantor Subsidiaries of the Company held 13% of the Company’s total consolidated assets and had $151.3 million in liabilities (excluding inter-company liabilities). In addition, the 2023 Indenture will not require any future Foreign Subsidiaries of the Company to guarantee the 2023 Notes unless they guarantee other Indebtedness of the Issuers. In the event of a bankruptcy, liquidation or reorganization of any non-guarantor Subsidiaries, the non-guarantor Subsidiaries will likely be required to repay financial and trade creditors before distributing any assets to the Issuers or a Guarantor.

As of the date of this prospectus, all of the Company’s Subsidiaries (other than Zayo Capital, Inc., the co-issuer) are “Restricted Subsidiaries.” However, under the circumstances described below under “—Certain Covenants—Designation of Restricted and Unrestricted Subsidiaries,” the Company will be permitted to designate certain of its Subsidiaries as “Unrestricted Subsidiaries.” Unrestricted Subsidiaries will not be subject to any of the restrictive covenants in the 2023 Indenture. Further, Unrestricted Subsidiaries will not Guarantee the 2023 Notes.

Although the 2023 Indenture contains limitations on the amount of additional Indebtedness that the Issuers, the Guarantors and the Restricted Subsidiaries may incur, the amount of such additional Indebtedness could be substantial.

The 2023 Notes will mature on April 1, 2023. The Issuers will issue up to $1.43 billion aggregate principal amount of 2023 Notes in this exchange offer. Subject to the covenant described under “—Certain Covenants—Limitation on Indebtedness,” the Issuers are permitted to issue additional notes under the 2023 Indenture (“Additional 2023 Notes”). The 2023 Notes and any Additional 2023 Notes that are issued will be treated as a single class under the 2023 Indenture, including with respect to waivers, amendments, redemptions and Offers to Purchase. The Additional 2023 Notes may be issued at different prices from the original issue price of the 2023 Notes in this offering. Unless the context otherwise requires, references to the “2023 Notes” for all purposes under the 2023 Indenture and in this “Description of 2023 Notes” include any Additional 2023 Notes that are issued.

Interest on the 2023 Notes will accrue from October 1, 2015, the most recent date to which interest has been paid or, if no interest has been paid, from and including January 23, 2015, at a rate per annum of 6.00%, and will be payable semiannually in arrears on April 1 and October 1 of each year. Interest will be payable to Holders of record on each Note in respect of the principal amount thereof outstanding as of the immediately preceding March 15 or September 15, as the case may be.

Interest will be computed on the basis of a 360-day year comprising twelve 30-day months. Interest on overdue principal and interest will accrue at a rate that is 2% higher than the then applicable interest rate on the 2023 Notes. In no event will the rate of interest on the 2023 Notes be higher than the maximum rate permitted by applicable law.

The 2023 Notes will be issued only in fully registered form without coupons and only in denominations of $2,000 and integral multiples of $1,000 in excess thereof.

The 2023 Notes will be initially in the form of one or more global notes (the “2023 Global Notes”). The 2023 Global Notes will be deposited with the Trustee as custodian for the Depository Trust Company (“DTC”). Ownership of interests in the 2023 Global Notes, referred to in this description as “book entry interests,” will be limited to Persons that have accounts with DTC or their respective participants. The terms of the 2023 Indenture will provide for the issuance of definitive registered 2023 Notes in certain circumstances. Please see the section entitled “—Book Entry, Delivery and Form.”

The registered Holder of a 2023 Note will be treated as the owner of it for all purposes.

A Holder may transfer or exchange 2023 Notes in accordance with the 2023 Indenture and the procedures described in “Notice to Investors.” The Registrar and the Trustee may require a Holder, among other things, to

furnish appropriate endorsements and transfer documents. No service charge will be made for any registration of transfer, exchange or redemption of the 2023 Notes, but the Issuers may require payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection with any such registration of transfer or exchange.

The Issuers are not required to transfer or exchange any 2023 Note selected for redemption. Also, the Issuers are not required to transfer or exchange any 2023 Note for a period of 15 days before a selection of 2023 Notes to be redeemed.

If a Holder has given wire transfer instructions to the Company at least ten Business Days prior to the applicable payment date, the Company will pay all principal, interest and premium, if any, on that Holder’s 2023 Notes in accordance with those instructions. All other payments on 2023 Notes will be made at the office or agency of the Paying Agent and Registrar unless the Company elects to make interest payments by check mailed to the Holders at their addresses set forth in the register of Holders; provided that all payments of principal, premium, if any, and interest, with respect to the 2023 Global Notes registered in the name of or held by DTC or its nominee and will be made by wire transfer of immediately available funds to the account specified by DTC.

The Trustee will initially act as Paying Agent and Registrar. The Company may change the Paying Agent or Registrar without prior notice to the Holders, and the Company or any of its Subsidiaries may act as Paying Agent or Registrar.

The Initial Guarantors jointly and severally guarantee the due and punctual payment of all amounts payable under the 2023 Notes, including principal, premium, if any, and interest. The 2023 Indenture requires any future Domestic Subsidiary, that is not designated as an Unrestricted Subsidiary, and any other Restricted Subsidiary that Guarantees Indebtedness of the Issuers or any Guarantor to provide a Note Guarantee. The ability of any future Domestic Subsidiaries to provide a Note Guarantee may be subject to prior approval by certain State PUCs. See “—Certain Covenants—Future Subsidiary 2023 Note Guarantees.”

Each 2023 Note Guarantee of a Guarantor is the Guarantor’s senior obligation. The 2023 Indenture states that each Guarantor under its 2023 Note Guarantee will be limited to an amount not to exceed the maximum amount that can be guaranteed by such Guarantor by law or without resulting in its obligations under its 2023 Note Guarantee being voidable or unenforceable under applicable laws relating to fraudulent transfer, or under similar laws affecting the rights of creditors generally. With respect to risks related to such limitations, see “Risk Factors—Risks Relating to the 2023 Notes—Federal and state statutes allow courts, under specific circumstances, to cancel the notes or the related guarantees and require noteholders to return payments received from us or the guarantors.” Each Guarantor that makes a payment or distribution under its 2023 Note Guarantee will be entitled to contribution from any other Guarantor.

A 2023 Note Guarantee of a Guarantor will be automatically and unconditionally released (and thereupon shall terminate and be discharged and be of no further force and effect):

(1) in connection with any sale or other disposition (including by merger or otherwise) of Capital Stock of the Guarantor after which such Guarantor is no longer a Subsidiary of the Company, if the sale of all such Capital Stock of that Guarantor complies with the applicable provisions of the 2023 Indenture;

(2) if the Company properly designates the Guarantor as an Unrestricted Subsidiary under the 2023 Indenture;

(3) solely in the case of a 2023 Note Guarantee created pursuant to the second paragraph of the covenant described below under “—Certain Covenants—Future Subsidiary 2023 Note Guarantees,” upon the release or discharge of the Guarantee that resulted in the creation of such 2023 Note Guarantee pursuant to that covenant, except a discharge or release by or as a result of payment under such 2023 Note Guarantee;

(4) upon a Legal Defeasance or satisfaction and discharge of the 2023 Indenture that complies with the provisions under “—Legal Defeasance and Covenant Defeasance” or “—Satisfaction and Discharge”; or

(5) upon payment in full of the aggregate principal amount of all 2023 Notes then outstanding and all other obligations under the 2023 Indenture and the 2023 Notes then due and owing.

Upon any occurrence giving rise to a release of a 2023 Note Guarantee as specified above, the Trustee will, at the written directions of the Company, execute any documents reasonably required in order to evidence or effect such release, termination and discharge in respect of such 2023 Note Guarantee. Neither the Issuers nor any Guarantor will be required to make a notation on the 2023 Notes to reflect any 2023 Note Guarantee or any such release, termination or discharge.

At any time prior to April 1, 2018, the Issuers may redeem up to 40% of the aggregate principal amount of 2023 Notes issued under the 2023 Indenture (including any Additional 2023 Notes) at a redemption price of 106.00% of the principal amount thereof, plus accrued and unpaid interest, if any, thereon to the redemption date, subject to the rights of Holders of 2023 Notes on the relevant record date to receive interest due on the relevant interest payment date, with the net cash proceeds of one or more Equity Offerings; provided that:

(1) at least 60% of the aggregate principal amount of 2023 Notes issued under the 2023 Indenture (including any Additional 2023 Notes) remains outstanding immediately after the occurrence of such redemption (excluding 2023 Notes held by the Issuers or their Affiliates); and

(2) the redemption must occur within 90 days of the date of the closing of such Equity Offering.

At any time prior to April 1, 2018, the Issuers may redeem all or part of the 2023 Notes at a redemption price equal to the sum of (i) 100% of the principal amount thereof, plus (ii) the Applicable Premium as of the date of redemption, plus (iii) accrued and unpaid interest, if any, to the date of redemption, subject to the rights of Holders of 2023 Notes on the relevant record date to receive interest due on the relevant interest payment date.

On or after April 1, 2018, the Issuers may redeem all or a part of the 2023 Notes, at the redemption prices (expressed as percentages of principal amount) set forth below plus accrued and unpaid interest, if any, thereon, to the applicable redemption date, subject to the rights of Holders of 2023 Notes on the relevant record date to receive interest due on the relevant interest payment date, if redeemed during the 12-month period beginning on April 1 of the years indicated below:

If less than all of the 2023 Notes are to be redeemed at any time, the 2023 Notes will be selected for redemption on a pro rata basis, by lot or by such other method as the Trustee deems fair and appropriate; provided, however that so long as the 2023 Notes are held through DTC, the 2023 Notes selected for redemption shall be selected in accordance with the applicable procedures of DTC.

No 2023 Notes of $2,000 or less will be redeemed in part. Notices of redemption will be delivered, at least 30 but not more than 60 days before the redemption date, to each Holder of 2023 Notes to be redeemed at its registered address. Notices of redemption may not be conditional.

If any 2023 Note is to be redeemed in part only, the notice of redemption that relates to that 2023 Note will state the portion of the principal amount thereof to be redeemed. A new 2023 Note in principal amount equal to the unredeemed portion of the original 2023 Note will be issued in the name of the Holder thereof upon cancellation of the original 2023 Note. 2023 Notes called for redemption become due on the date fixed for redemption. On and after the redemption date, interest will cease to accrue on 2023 Notes or portions thereof called for redemption.

Unless the Issuers have previously or concurrently delivered a redemption notice with respect to all the outstanding 2023 Notes as described under “—Optional Redemption,” the Issuers must commence, within 30 days of the occurrence of a Change of Control, and consummate an Offer to Purchase for all 2023 Notes then outstanding, at a purchase price in cash equal to 101% of the aggregate principal amount of the 2023 Notes repurchased, plus accrued and unpaid interest, if any, thereon, to the date of repurchase, subject to the rights of Holders of 2023 Notes on the relevant record date to receive interest due on the relevant interest payment date.

The Issuers’ ability to pay cash to the Holders of the 2023 Notes following the occurrence of a Change of Control may be limited by the Issuers’ then-existing financial resources. Sufficient funds may not be available when necessary to make any required repurchases. See “Risk Factors—Risks Relating to the 2023 Notes—We may not be able to repurchase the notes upon a change of control or asset sale.”

The Change of Control purchase feature of the 2023 Notes may in certain circumstances make more difficult or discourage a sale or takeover of the Issuers and, thus, the removal of incumbent management. The Change of Control purchase feature is a result of negotiations between the Initial Purchasers and the Company. As of the date of this prospectus, the Issuers have no present intention to engage in a transaction involving a Change of Control, although it is possible that the Issuers could decide to do so in the future. Subject to the limitations discussed below, the Issuers could, in the future, enter into certain transactions, including acquisitions, refinancings or other recapitalizations, that would not constitute a Change of Control under the 2023 Indenture, but that could increase the amount of Indebtedness outstanding at such time or otherwise affect the Company’s capital structure or credit ratings. Restrictions on the Company’s ability to Incur additional Indebtedness are contained in the covenants described below under “—Certain Covenants—Limitation on Indebtedness.”

The Issuers 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 2023 Indenture applicable to an Offer to Purchase made by the Issuers and purchases all 2023 Notes validly tendered and not withdrawn under such Offer to Purchase.

If holders of not less than 90% in aggregate principal amount of the outstanding 2023 Notes validly tender and do not withdraw such notes in connection with an Offer to Purchase upon a Change of Control and the Company, or any third party making a Change of Control offer in lieu of the Company as described above, purchases all of the 2023 Notes validly tendered and not withdrawn by such holders, the Company or such third party will have the right, upon not less than 15 days nor more than 60 days’ prior notice, provided that such notice is given not more than 30 days following such purchase date, to redeem all 2023 Notes that remain outstanding following such purchase at a price equal to the price offered to each other holder in such tender offer plus accrued and unpaid interest, if any, to, but not including, the applicable redemption date.

Restricted Subsidiaries taken as a whole. Although there is a limited body of case law interpreting the phrase “substantially all,” there is no precise established definition of the phrase under applicable law. Accordingly, the ability of a Holder of 2023 Notes to require the Issuers to repurchase such 2023 Notes as a result of a sale, transfer, conveyance or other disposition of less than all of the assets of the Company and the Restricted Subsidiaries taken as a whole to another Person or group may be uncertain. See “Risk Factors—Risks Relating to the Notes—The ability of holders of notes to require us to repurchase notes as a result of a disposition of “substantially all” of our assets or a change in the composition of our board of directors is uncertain.”

The Company will not, and will not permit any Restricted Subsidiary to, consummate an Asset Sale unless:

(1) the Company (or the Restricted Subsidiary, as the case may be) receives consideration at the time of such Asset Sale at least equal to the Fair Market Value of the assets or Equity Interests issued or sold or otherwise disposed of; and

(2) at least 75% of the consideration therefor received by the Company or such Restricted Subsidiary is in the form of:

(a) Cash Equivalents (including any Cash Equivalents received from the conversion within 180 days of such Asset Sale of any securities, notes or other obligations received in consideration of such Asset Sale);

(c) any Designated Noncash Consideration received by the Company or any of its Restricted Subsidiaries in such Asset Sale having an aggregate Fair Market Value, taken together with all other Designated Noncash Consideration received pursuant to this clause (c) that is at that time outstanding, not to exceed the greater of (x) 3.0% of Consolidated Total Assets and (y) $150 million (with the Fair Market Value of each item of Designated Noncash Consideration being measured at the time received and without giving effect to subsequent changes in value); or

Any Net Available Cash received by the Company or any Restricted Subsidiary from any Asset Sale may be applied within 365 days of receipt of such Net Available Cash, to permanently reduce any Indebtedness constituting Indebtedness of a non-Guarantor Subsidiary or to permanently reduce any senior Indebtedness of the Issuers or any Guarantor (in each case owing to a Person other than the Company or any Affiliate of the Company) (and, if the obligation repaid is revolving credit Indebtedness, to correspondingly reduce loan commitments with respect thereto).

The amount of such Net Available Cash required to be applied (or to be committed to be applied) during such 365-day period as set forth in the preceding paragraph and not applied (or committed to be applied) as so required by the end of such period, or used to consummate an Offer to Purchase pursuant to any indenture or similar document governing Permitted Additional Secured Obligations, shall constitute “Excess Proceeds.” If, as of the first day of any calendar month, the aggregate amount of Excess Proceeds totals at least $50 million, the Company must commence, not later than the 15th Business Day of such month, and consummate an Offer to Purchase, from the Holders and all holders of other Pari Passu Debt containing provisions similar to those set forth in the 2023 Indenture with respect to offers to purchase with the proceeds of sales of assets, the maximum principal amount of 2023 Notes and such other Pari Passu Debt that may be purchased out of the Excess Proceeds; provided that the amount of Excess Proceeds required to be used to make an Offer to Purchase pursuant to this paragraph shall be reduced by any mandatory prepayments made under any Series of Pari Passu Debt in respect of such Excess Proceeds (and which prepayments shall not be in excess of such Series pro rata share of such Excess Proceeds). The offer price in any such Offer to Purchase will be equal to 100% of the principal amount (or accreted value, if applicable) of the 2023 Notes and such other Pari Passu Debt plus accrued

and unpaid interest, if any, to the date of purchase, subject to the rights of Holders of 2023 Notes on the relevant record date to receive interest on the relevant interest payment date, and will be payable in cash. To the extent that any Excess Proceeds remain after consummation of an Offer to Purchase pursuant to this “—Repurchase at the Option of Holders Asset Sales” covenant, the Company may use those Excess Proceeds for any purpose not otherwise prohibited by the 2023 Indenture, and those Excess Proceeds shall no longer constitute “Excess Proceeds.”

For the purposes of this covenant, the following are deemed to be Cash Equivalents: the assumption of (i) Indebtedness of the Company (other than Disqualified Stock or Indebtedness that is by its terms subordinated in right of payment to the 2023 Notes); (ii) Indebtedness of any Restricted Subsidiary (other than Indebtedness of a Guarantor that is by its terms subordinated in right of payment to the 2023 Notes or Disqualified Stock of any Guarantor) or (iii) any liabilities (as shown on the Company’s or such Restricted Subsidiary’s most recent balance sheet) of the Company or any Restricted Subsidiary (other than contingent liabilities, Indebtedness that is by its terms subordinated to the 2023 Notes or any 2023 Note Guarantee and liabilities to the extent owed to the Company or any Subsidiary of the Company) and, in each case, the full and unconditional release of the Company or such Restricted Subsidiary from all liability on such Indebtedness in connection with such Asset Sale.

(a) the 2023 Notes have achieved an Investment Grade Rating from both of the Ratings Agencies; and

(b) no Default or Event of Default has occurred and is continuing under the 2023 Indenture,

then, beginning on that day and continuing until the Reversion Date (as defined below), the Company and its Restricted Subsidiaries will not be subject to the provisions of the 2023 Indenture summarized under the following headings (collectively, the “Suspended Covenants”):

If at any time the 2023 Notes cease to have such Investment Grade Rating by either Rating Agency or if a Default or Event of Default occurs and is continuing, then the Suspended Covenants will, from such date and thereafter be reinstated as if such covenants had never been suspended (the “Reversion Date”) and be applicable pursuant to the terms of the 2023 Indenture (including in connection with performing any calculation or assessment to determine compliance with the terms of the 2023 Indenture), unless and until the 2023 Notes subsequently attain an Investment Grade Rating from both Ratings Agencies and no Default or Event of Default is in existence (in which event the Suspended Covenants shall no longer be in effect for such time that the 2023 Notes maintain an Investment Grade Rating from both Ratings Agencies and no Default or Event of Default is in

existence); provided, however, that no Default, Event of Default or breach of any kind shall be deemed to exist under the 2023 Indenture, the 2023 Notes or the Guarantees with respect to the Suspended Covenants based on, and none of the Company or any of its Subsidiaries shall bear any liability for, any actions taken or events occurring during the Suspension Period (as defined below), or any actions taken at any time pursuant to any contractual obligation arising prior to the Reversion Date, regardless of whether such actions or events would have been permitted if the applicable Suspended Covenants remained in effect during such period. The period of time between the date of suspension of the covenants and the Reversion Date is referred to as the “Suspension Period.”

On the Reversion Date, all Indebtedness Incurred during the Suspension Period will be classified to have been Incurred pursuant to one of the clauses (other than pursuant to clause (2)) set forth in the first paragraph of “—Certain Covenants—Limitation on Indebtedness” (to the extent such Indebtedness would be permitted to be Incurred thereunder as of the Reversion Date and after giving effect to the Indebtedness Incurred prior to the Suspension Period and outstanding on the Reversion Date). To the extent such Indebtedness would not be so permitted to be Incurred pursuant to “—Certain Covenants—Limitation on Indebtedness,” such Indebtedness will be deemed to have been outstanding on the Issue Date, so that it is classified as permitted under clause (2) of “—Certain Covenants—Limitation on Indebtedness.” Calculations made after the Reversion Date of the amount available to be made as Restricted Payments under “—Certain Covenants—Limitation on Restricted Payments” will be made as though the covenants described under “—Certain Covenants—Limitation on Restricted Payments” had been in effect since the 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 “—Certain Covenants—Limitation on Restricted Payments” to the extent set forth in such covenant.

There can be no assurance that the 2023 Notes will ever achieve or maintain an Investment Grade Rating.

(A) The Company will not, and will not permit any Restricted Subsidiary to, directly or indirectly, take any of the following actions (each, a “Restricted Payment”):

(I) declare or pay any dividend or make any other payment or distribution with respect to any of the Company’s or any Restricted Subsidiary’s Equity Interests (including, without limitation, any payment in connection with any merger or consolidation involving the Company or any Restricted Subsidiary) or to the direct or indirect holders of the Company’s or any Restricted Subsidiary’s Equity Interests in their capacity as such (other than dividends, payments or distributions (x) payable in Equity Interests (other than Disqualified Stock) of the Company or (y) to the Company or a Restricted Subsidiary);

(II) purchase, redeem or otherwise acquire or retire for value (including, without limitation, in connection with any merger or consolidation involving the Company or any Restricted Subsidiary) any Equity Interests of the Company held by any Person (other than by a Restricted Subsidiary) or any Equity Interests of any Restricted Subsidiary held by any Person (other than by the Company or another Restricted Subsidiary);

(III) call for redemption or make any payment on or with respect to, or purchase, redeem, defease or otherwise acquire or retire for value, prior to the Stated Maturity thereof, any Indebtedness that is subordinated in right of payment to the 2023 Notes or any 2023 Note Guarantee except (a) in anticipation of satisfying a sinking fund obligation, principal installment or final maturity, in each case due within one year of the date of such payment, purchase, repurchase or other acquisition or (b) intercompany Indebtedness permitted to be Incurred pursuant to clause (6) of the second paragraph of the covenant described below under “—Certain Covenants—Limitation on Indebtedness”; or

(IV) make any Investment (other than a Permitted Investment) in any Person; unless, at the time of and after giving pro forma effect to such Restricted Payment:

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

(2) the Company could Incur at least $1.00 of additional Indebtedness pursuant to the Consolidated Leverage Ratio test set forth in the first paragraph of the covenant described below under “—Certain Covenants—Limitation on Indebtedness”; and

(3) such Restricted Payment, together with the aggregate amount of all other Restricted Payments made by the Company and the Restricted Subsidiaries after July 1, 2012 (excluding Restricted Payments permitted by clauses (2), (3), (4), (5), (6), (7), (8), (10), and (11) of the next succeeding paragraph (B) and provided that Restricted Payments under clauses (1), (9) and (12) of the next succeeding paragraph (B) shall not cause availability under this clause (3) to be less than zero), is less than the sum, without duplication, of:

(a) (x) the aggregate Consolidated Cash Flow accrued in the period beginning on the first day of the quarter beginning on July 1, 2012, and ending on the last day of the most recent quarter for which internal financial statements are available prior to the date of such proposed Restricted Payment (or, if such Consolidated Cash Flow for such period is a deficit, less 100% of such deficit), less (y) 1.5 times consolidated interest expense during such period; plus

(b) the aggregate net cash proceeds and the fair market value of securities or other property received by the Company after July 2, 2012 as a contribution to its common equity capital or from the issue, sale or exchange of Equity Interests (other than Disqualified Stock) of the Company and the amount of reduction of Indebtedness of the Company or its Restricted Subsidiaries that has been converted into or exchanged for such Equity Interests (other than Equity Interests sold to, or Indebtedness held by, a Subsidiary of the Company); plus

(c) with respect to Investments (other than Permitted Investments) made by the Company and the Restricted Subsidiaries after July 2, 2012, an amount equal to the net reduction in such Investments in any Person (except, in each case, to the extent any such amount is included in the calculation of Consolidated Net Income), resulting from repayment to the Company or any Restricted Subsidiary of loans or advances or from the receipt of net cash proceeds from the sale of any such Investment, from the release of any Guarantee (except to the extent any amounts are paid under such Guarantee) or from redesignations of Unrestricted Subsidiaries as Restricted Subsidiaries, not to exceed, in each case, the amount of such Investments previously made by the Company or any Restricted Subsidiary in such Person; plus

As of June 30, 2015, we had at least $1,967 million available to make Restricted Payments under clause (3) of the immediately preceding paragraph above.

(B) The preceding provisions will not prohibit the following; provided that, in the case of clauses (7) and (8) below only, no default in payment of interest, principal, or premium on the 2023 Notes has occurred and is continuing:

(1) the payment of any dividend within 60 days after the date of declaration thereof, if at said date of declaration such payment would have complied with the provisions of the 2023 Indenture, and the redemption of any Indebtedness that is subordinated in right of payment to the 2023 Notes or the 2023 Note Guarantees within 60 days after the date on which notice of such redemption was given, if at said date of the giving of such notice, such redemption would have complied with the provisions of the 2023 Indenture;

(2) the payment of any dividend or other distribution by a Restricted Subsidiary to all the holders of its Equity Interests on a pro rata basis;

(3) any Restricted Payment in exchange for, or out of the net cash proceeds of a contribution to the common equity of the Company or a substantially concurrent sale (other than to a Subsidiary of the Company) of, Equity Interests (other than Disqualified Stock) of the Company; provided that the amount of any such net cash proceeds that are utilized for such Restricted Payment will be excluded from clause (3) (b) of the preceding paragraph (A);

(4) the redemption, repurchase, defeasance or other acquisition or retirement for value of Indebtedness that is subordinated in right of payment to the 2023 Notes or the 2023 Note Guarantees in exchange for or with the net cash proceeds from a substantially concurrent Incurrence (other than to a Subsidiary of the Company) of, Permitted Refinancing Indebtedness;

(5) the repurchase of Capital Stock deemed to occur upon the exercise of options or warrants to the extent that such Capital Stock represents all or a portion of the exercise price thereof and applicable withholding taxes, if any;

(6) the payment of cash in lieu of fractional Equity Interests pursuant to the exchange or conversion of any exchangeable or convertible securities; provided, that such payment shall not be for the purpose of evading the limitations of this covenant (as determined by the Board of Directors of the Company in good faith);

(7) the declaration and payment of dividends to holders of any class or series of Disqualified Stock of the Company or any Restricted Subsidiary, or Preferred Stock of a Restricted Subsidiary, in each case issued in accordance with the covenant described below under “—Certain Covenants—Limitation on Indebtedness”;

(8) the repurchase, redemption or other acquisition or retirement for value of any Equity Interests of the Company, or the dividend or other distribution, directly or indirectly, to Parent, to fund the repurchase, redemption or other acquisition or retirement for value of any Equity Interests of Parent, in each case held by any current or former employee or director of the Company (or any Subsidiaries) pursuant to the terms of any employee equity subscription agreement, stock option agreement or similar agreement entered into in the ordinary course of business; provided that the aggregate price paid, or distributed or paid out as a dividend under this clause (8) in any calendar year will not exceed $30 million (with unused amounts in any calendar year being carried over to succeeding years) or, in the event any unused amounts of any previous year are being carried over, $60 million;

(9) the declaration and payment of dividends on the Company’s Equity Interests (or a Restricted Payment to Parent to fund a payment of dividends on Parent’s Equity Interests) of up to 6% per annum of the net cash proceeds received by (or, in the case of a Restricted Payment to Parent, contributed to the capital of) the Company in or from any public equity offering of common stock after July 2, 2012;

(10) other Restricted Payments in an aggregate amount not to exceed the greater of (i) $150 million and (ii) 3.0% of the Consolidated Total Assets;

(11) the declaration and payment of dividends by the Company to, or the making of the loans to, Parent in amounts required for Parent to pay, in each case without duplication, (a) franchise taxes and other fees, taxes and expenses required to maintain their corporate existence; (b) foreign, federal, state and local income taxes, to the extent such income taxes are (i) attributable to the income of the Company and their Restricted Subsidiaries and (ii) required to be paid by Parent, and only for so long as the Company is treated as a pass-through entity for U.S. federal income tax purposes; provided that in each case the amount of such payments in any fiscal year does not exceed the amount that Company and its Restricted Subsidiaries would be required to pay in respect of its foreign, federal, state and local taxes for such fiscal year were the Company and its Restricted Subsidiaries to pay such taxes separately from any such parent entity; (c) customary salary, bonus and other benefits payable to officers and employees of Parent to the extent such salaries, bonuses and other benefits are attributable to the ownership or operation of the Company and its Restricted Subsidiaries; (d) general corporate operating and overhead costs and expenses of Parent to the extent such costs and expenses are attributable to the ownership or operation of the Company and its Restricted Subsidiaries; and (e) amounts required for Parent to pay fees and expenses incurred by Parent related to the maintenance of Parent of its corporate or other entity existence; and

(12) other Restricted Payments so long as, after giving pro forma effect to the payment of such Restricted Payment, the Consolidated Leverage Ratio would be positive and less than 3.75 to 1.00.

The amount of all Restricted Payments (other than cash) will be the Fair Market Value on the date of the Restricted Payment of the asset(s) or securities proposed to be transferred or issued to or by the Company or such Subsidiary, as the case may be, pursuant to the Restricted Payment.

The Company will not, and will not permit any Restricted Subsidiary to, Incur any Indebtedness; provided that the Company or any Guarantor may Incur Indebtedness if, after giving effect to the Incurrence of such Indebtedness and the receipt and application of the proceeds therefrom, the Consolidated Leverage Ratio would be positive and less than 6.00 to 1.00.

The first paragraph of this covenant will not prohibit the Incurrence of any of the following items of Indebtedness (collectively, “Permitted Indebtedness”):

(1) the Incurrence by the Company or any Guarantor of Indebtedness under the Credit Facilities (including, without limitation, the Incurrence by the Company and the Guarantors of Guarantees thereof) in an aggregate amount at any one time outstanding pursuant to this clause (1) not to exceed (x) $3.0 billion, plus (y) an additional amount that does not cause the Consolidated Secured Debt Ratio of the Company and its Restricted Subsidiaries to exceed 4.50 to 1.00;

(3) the Incurrence by the Company and the Guarantors of Indebtedness represented by the 2023 Notes (other than Additional 2023 Notes) and the related 2023 Note Guarantees;

(4) the Incurrence by the Company or any Guarantor of Indebtedness represented by Capital Lease Obligations, mortgage financings or purchase money obligations, in each case, Incurred for the purpose of financing all or any part of the purchase price or cost of construction or improvement of property, plant or equipment used in the business of the Company or such Guarantor, whether through the direct acquisition of such assets or the acquisition of Equity Interest of any person owning such assets (including any reasonably related fees or expenses Incurred in connection with such acquisition, construction or improvement), in an aggregate amount, including all Permitted Refinancing Indebtedness Incurred to refund, refinance or replace any Indebtedness Incurred pursuant to this clause (4), not to exceed, at any time outstanding, the greater of (i) $200 million and (ii) 4.0% of the Consolidated Total Assets;

(5) the Incurrence by the Company or any Restricted Subsidiary of Permitted Refinancing Indebtedness in exchange for, or the net cash proceeds of which are used to refund, refinance or replace Indebtedness that was permitted by the 2023 Indenture to be Incurred under the first paragraph of this covenant or clauses (2), (3), (5), (14) or (15) of this paragraph;

(6) the Incurrence by the Company or any Restricted Subsidiary of Indebtedness owing to and held by the Company or any Restricted Subsidiary; provided that:

(a) if the Company or any Guarantor is the obligor on such Indebtedness and such Indebtedness is owed to a non-Guarantor Restricted Subsidiary, such Indebtedness must be unsecured and expressly subordinated in right of payment to the prior payment in full in cash of all Obligations with respect to the 2023 Notes, in the case of the Company, or the 2023 Note Guarantee, in the case of a Guarantor; and

(b) any event that results in any such Indebtedness being held by a Person other than the Company or a Restricted Subsidiary (except for any pledge of such Indebtedness constituting a Permitted Lien until the pledgee commences actions to foreclose on such Indebtedness) will be deemed, in each case, to constitute an Incurrence of such Indebtedness by the Company or such Restricted Subsidiary, as the case may be, that was not permitted by this clause (6);

(7) the Guarantee by the Company or any Guarantor of Indebtedness of the Company or a Restricted Subsidiary that was permitted to be Incurred by another provision of this covenant;

(8) the Incurrence by the Company or any Guarantor of Hedging Obligations that are Incurred for the purpose of fixing, hedging or swapping interest rate, commodity price or foreign currency exchange rate risk (or to reverse or amend any such agreements previously made for such purposes), and not for speculative purposes;

(9) the Incurrence by the Company or any Guarantor of Indebtedness arising from agreements providing for indemnification, adjustment of purchase price or similar obligations, or Guarantees or letters of credit, surety bonds or performance bonds securing any obligations of the Company or any Restricted Subsidiary pursuant to such agreements, in any case Incurred in connection with the disposition or acquisition of any business, assets or Capital Stock of a Guarantor (other than Guarantees of Indebtedness Incurred by any Person acquiring all or any portion of such business, assets or Capital Stock of a Guarantor for the purpose of financing such acquisition), so long as the amount does not exceed the gross proceeds actually received by the Company or any Guarantor in connection with such disposition;

(10) the Incurrence by the Company or any Restricted Subsidiary of Indebtedness arising from the honoring by a bank or other financial institution of a check, draft or similar instrument drawn against insufficient funds in the ordinary course of business; provided that such Indebtedness is extinguished within five Business Days of its Incurrence;

(11) the Incurrence by the Company or any Guarantor of Indebtedness in respect of bid, performance or surety bonds or letters of credit issued in the ordinary course of business, including letters of credit supporting lease obligations or supporting such bid, performance or surety bonds or in respect of workers’ compensation claims, or other Indebtedness with respect to reimbursement obligations regarding workers’ compensation claims; provided that, upon the drawing of such letters of credit or the Incurrence of such repayment or reimbursement obligations under any such bid, performance or surety bonds, such obligations are reimbursed within 30 days following such drawing or Incurrence;

(12) the Incurrence by the Company or any Restricted Subsidiary of Indebtedness to the extent the net cash proceeds thereof are promptly deposited to defease or to satisfy and discharge the 2023 Notes as described below under “—Legal Defeasance and Covenant Defeasance” or “—Satisfaction and Discharge”;

(13) customer deposits and advance payments received from customers for goods and services sold in the ordinary course of business;

(14) the Incurrence of Acquired Debt; provided that after giving effect to the Incurrence thereof, the Company could incur at least $1.00 of additional Indebtedness pursuant to the Consolidated Leverage Ratio test set forth in the first paragraph above;

(15) the Incurrence by the Company or any Guarantor of additional Indebtedness in an aggregate amount at any one time outstanding, including all Permitted Refinancing Indebtedness Incurred to refund, refinance or replace any Indebtedness Incurred pursuant to this clause (15), not to exceed the greater of (i) $250 million and (ii) 5.0% of Consolidated Total Assets; or

(16) the Indebtedness of a Receivables Subsidiary in respect of a Receivables Facility, which is non-recourse to the Issuers or any other Restricted Subsidiary in any way other than Standard Securitization Undertakings.

For purposes of determining compliance with this covenant, in the event that any proposed Indebtedness meets the criteria of more than one of the categories described in clauses (1) through (16) above, or is entitled to be Incurred pursuant to the first paragraph of this covenant, the Company will be permitted to classify, and may later reclassify, such item of Indebtedness or a part thereof in any manner that complies with this covenant. Notwithstanding the foregoing, Indebtedness under the Credit Facilities outstanding on the Issue Date, if any, will be deemed to have been Incurred on such date in reliance on the exception provided by clause (1) above and shall not be reclassified.

For purposes of determining compliance with any U.S. dollar-denominated restriction on the Incurrence of Indebtedness, the U.S. Dollar Equivalent principal amount of Indebtedness denominated in a foreign currency shall be calculated based on the relevant currency exchange rate in effect on the date such Indebtedness was Incurred (or first committed, in the case of revolving credit debt); provided that if such Indebtedness is Incurred to refinance other Indebtedness denominated in a foreign currency, and such refinancing would cause the applicable U.S. dollar denominated restriction to be exceeded if calculated at the relevant currency exchange rate in effect on the date of such refinancing, such U.S. dollar-denominated restriction shall be deemed not to have been exceeded so long as the principal amount of such refinancing Indebtedness does not exceed the principal amount of such Indebtedness being refinanced.

The principal amount of any Indebtedness Incurred to refinance other Indebtedness, if Incurred in a different currency from the Indebtedness being refinanced, shall be calculated based on the currency exchange rate applicable to the currencies in which such respective Indebtedness is denominated that is in effect on the date of such refinancing.

The accretion of original issue discount shall be deemed not to be an Incurrence of Indebtedness.

The Company will not Incur any Indebtedness that is contractually subordinate in right of payment to any other Indebtedness of the Company unless it is contractually subordinate in right of payment to the 2023 Notes at least to the same extent. The Company will not permit the co-issuer or any Guarantor to Incur any Indebtedness that is contractually subordinate in right of payment to any other Indebtedness of the co-issuer or such Guarantor, as the case may be, unless it is contractually subordinate in right of payment to the 2023 Notes or such Guarantor’s 2023 Note Guarantee, as the case may be, at least to the same extent. For purposes of the 2023 Indenture, no Indebtedness will be deemed to be contractually subordinated in right of payment to any other Indebtedness of the Issuers or any Guarantor, as applicable, solely by reason of any Liens or Guarantees arising or created in respect thereof.

The Company will not, and will not permit any Restricted Subsidiary to, create, incur, assume or otherwise cause or suffer to exist or become effective any Lien of any kind (other than Permitted Liens) upon any of their property or assets, now owned or hereafter acquired unless all payments due under the 2023 Indenture and the 2023 Notes are secured on an equal and ratable basis with the obligations so secured until such time as such obligations are no longer secured by a Lien.

Limitation on Dividend and Other Payment Restrictions Affecting Restricted Subsidiaries

The Company will not, and will not permit any Restricted Subsidiary to, directly or indirectly, create or permit to exist or become effective any consensual encumbrance or restriction on the ability of any Restricted Subsidiary to:

(1) pay dividends or make any other distributions on its Capital Stock (or with respect to any other interest or participation in, or measured by, its profits) to the Company or any Restricted Subsidiary (it being understood that the priority of any Preferred Stock in receiving dividends or liquidating distributions prior to dividends or liquidating distributions being paid on Common Stock shall not be deemed a restriction on the ability to make distributions on Capital Stock);

(3) make loans or advances to the Company or any Restricted Subsidiary (it being understood that the subordination of loans or advances made to the Company or any Restricted Subsidiary to other Indebtedness Incurred by the Company or any Restricted Subsidiary shall not be deemed a restriction on the ability to make loans or advances); or

(4) transfer any of its properties or assets to the Company or any Restricted Subsidiary.

However, the preceding restrictions will not apply to encumbrances or restrictions:

(1) existing under, by reason of or with respect to the Credit Facilities as in effect on the Issue Date or Existing Indebtedness, or any other agreements in effect on the Issue Date and any amendments, modifications, restatements, renewals, extensions, supplements, refundings, replacements or refinancings thereof; provided that the encumbrances and restrictions in any such amendments, modifications, restatements, renewals, extensions, supplements, refundings, replacements or refinancings, taken as a whole, are not, as determined by the Company in good faith, materially more restrictive than those contained in, as the case may be, the Credit Facilities or the Security Documents as in effect on the Issue Date or Existing Indebtedness or such other agreements, as the case may be, as in effect on the Issue Date;

(2) set forth in the 2023 Indenture, the 2023 Notes and the 2023 Note Guarantees;

(4) with respect to any Person or the property or assets of a Person acquired by the Company or any Restricted Subsidiary existing at the time of such acquisition and not incurred in connection with or in contemplation of such acquisition, which encumbrance or restriction is not applicable to any Person, or the properties or assets of any Person, other than the Person, or the property or assets of the Person, so acquired, and any amendments, modifications, restatements, renewals, extensions, supplements, refundings, replacements or refinancings thereof; provided that the encumbrances and restrictions in any such amendments, modifications, restatements, renewals, extensions, supplements, refundings, replacements or refinancings, taken as a whole, are not, as determined by the Company in good faith, materially more restrictive than those in effect on the date of the acquisition;

(5) that restrict in a customary manner the subletting, assignment or transfer of any property or asset that is a lease, license, conveyance or contract or similar property or asset;

(6) existing by virtue of any transfer of, agreement to transfer, option or right with respect to, or Lien on, any property or assets of the Company or any Restricted Subsidiary not otherwise prohibited by the 2023 Indenture;

(7) arising or agreed to in the ordinary course of business, not relating to any Indebtedness, and that do not, individually or in the aggregate, detract from the value of property or assets of the Company or any Restricted Subsidiary in any manner material to the Company or any Restricted Subsidiary, as determined by the Company in good faith;

(8) that restrict distributions or transfer by a Restricted Subsidiary if such restrictions exist under, by reason of or with respect to any agreement for the sale or other disposition of all or substantially all of the Capital Stock of, or property and assets of, that Restricted Subsidiary and are pending such sale or other disposition;

(9) on cash or other deposits or net worth, which encumbrances or restrictions are imposed by customers or suppliers or required by insurance, surety or bonding companies, in each case, under contracts entered into in the ordinary course of business;

(10) arising from customary provisions in joint venture agreements and other similar agreements entered into in the ordinary course of business and which the Board of Directors of the Company determines in good faith will not adversely affect the Issuers’ ability to make payments of principal or interest on the 2023 Notes;

(11) arising from purchase money obligations Incurred in compliance with clause (4) of the covenant described above under “—Certain Covenants—Limitation on Indebtedness” that impose restrictions of the nature described in clause (4) above on the assets acquired; and

(12) existing under, by reason of, or with respect to Indebtedness of any Restricted Subsidiary that is a Foreign Subsidiary; provided that the Issuers’ Boards of Directors determine in good faith at the time such encumbrances or restrictions are created that they do not adversely affect such Issuer’s ability to make prepayments of principal or interest on the 2023 Notes.

The Issuers. The Issuers will not, directly or indirectly: (1) consolidate or merge with or into another Person (whether or not such Issuer is the surviving corporation), or (2) sell, assign, transfer, convey or otherwise dispose of all or substantially all of the properties and assets of the Issuers and the Restricted Subsidiaries taken as a whole, in one or more related transactions, to another Person, unless:

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

(b) the Person formed by or surviving any such consolidation or merger (if other than such Issuer) or to which such sale, assignment, transfer, conveyance or other disposition will have been made (i) is a Person organized or existing under the laws of the United States, any state thereof or the District of Columbia; provided that in the case where such Person is not a corporation, a co-obligor of the 2023 Notes is a corporation organized or existing under such laws and (ii) assumes all the obligations of such Issuer under the 2023 Notes and the 2023 Indenture pursuant to a supplemental indenture reasonably satisfactory to the Trustee;

(3) immediately after giving effect to such transaction on a pro forma basis, (i) such Issuer or the Person formed by or surviving any such consolidation or merger (if other than such Issuer), or to which such sale, assignment, transfer, conveyance or other disposition will have been made, will be permitted to Incur at least $1.00 of additional Indebtedness pursuant to the Consolidated Leverage Ratio test set forth in the first paragraph of the covenant described above under “—Certain Covenants—Limitation on Indebtedness”; or (ii) the Consolidated Leverage Ratio is positive and less than the Company’s Consolidated Leverage Ratio immediately prior to such transaction;

(4) each Guarantor, unless such Guarantor is the Person with which such Issuer has entered into a transaction under this covenant, will have confirmed to the Trustee in writing that its 2023 Note Guarantee will apply to the obligations of such Issuer or the surviving Person in accordance with the 2023 Notes and the 2023 Indenture; and

(5) the Company delivers to the Trustee an Officers’ Certificate (attaching the arithmetic computation to demonstrate compliance with clause (3) above) and Opinion of Counsel, in each case stating that such transaction and such agreement comply with this covenant and that all conditions precedent provided for in the 2023 Indenture relating to such transaction have been complied with;

provided that clause (3) above will not apply (i) if, in the good faith determination of the Board of Directors of the Company, whose determination shall be evidenced by a Board Resolution, the principal purpose of such transaction is to change the state of incorporation of the Company, and such transaction does not have as one of its purposes the evasion of the foregoing limitations; or (ii) to any consolidation, merger, sale, assignment, transfer, conveyance or other disposition of assets between or among such Issuer and any Guarantor.

Upon any consolidation, merger, sale, assignment, transfer, conveyance or other disposition in accordance with this covenant, the successor Person formed by such consolidation or into or with which such Issuer is merged or to which such sale, assignment, transfer, conveyance or other disposition is made will succeed to, and be substituted for (so that from and after the date of such consolidation, merger, sale, assignment, conveyance or other disposition, the provisions of the 2023 Indenture referring to the “Issuers” will refer instead to the successor Person and not to such Issuer), and may exercise every right and power of, such Issuer under the 2023 Indenture with the same effect as if such successor Person had been named as an Issuer in the 2023 Indenture. In the event of any such transfer, the predecessor will be released and discharged from all liabilities and obligations in respect of the 2023 Notes and the 2023 Indenture and the predecessor may be dissolved, wound up or liquidated at any time thereafter.

In addition, the Company and the Restricted Subsidiaries may not, directly or indirectly, lease all or substantially all of the properties or assets of the Company and the Restricted Subsidiaries considered as one enterprise, in one or more related transactions, to any other Person.

Although there is a limited body of case law interpreting the phrase “all or 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 “all or substantially all” of the property or assets of a Person. See “Risk Factors—Risks Relating to the Notes—The ability of holders of notes to require us to repurchase notes as a result of a disposition of ‘substantially all’ of our assets or a change in the composition of our board of directors is uncertain.”

The Guarantors. A Guarantor will not, directly or indirectly: (1) consolidate or merge with or into another Person (whether or not such Guarantor is the surviving Person), or (2) sell, assign, transfer, convey or otherwise dispose of all or substantially all of the properties and assets of the Guarantor, in one or more related transactions, to another Person, other than the Company or another Guarantor, unless:

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

(a) the Guarantor is the surviving corporation, or the Person formed by or surviving any such consolidation or merger (if other than the Guarantor) or to which such sale, assignment, transfer, conveyance or other disposition which has been made (i) is organized or existing under the laws of the United States, any state thereof or the District of Columbia and (ii) assumes all the obligations of that Guarantor under the 2023 Indenture, including its 2023 Note Guarantee, pursuant to a supplemental indenture satisfactory to the Trustee; or

(b) such sale, assignment, transfer, conveyance or other disposition or consolidation or merger complies with the covenant described above under “—Repurchase at the Option of Holders—Asset Sales.”

The Company will not, and will not permit any Restricted Subsidiary to, directly or indirectly make any payment to, or sell, lease, transfer or otherwise dispose of any of its properties or assets to, or purchase any property or assets from, or enter into, make, amend, renew or extend any transaction, contract, agreement, understanding, loan, advance or Guarantee with, or for the benefit of, any of their Affiliates (each, an “Affiliate Transaction”) involving aggregate payments or consideration in excess of $10 million, unless:

(1) such Affiliate Transaction is on fair and reasonable terms that are no less favorable to the Company or the relevant Restricted Subsidiary than those that would have been obtained in a comparable arm’s-length transaction by the Company or such Restricted Subsidiary with a Person that is not an Affiliate of the Company or any Restricted Subsidiary; and

(a) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $25 million, a Board Resolution attached to in an Officers’ Certificate certifying that such Affiliate Transaction or series of related Affiliate Transactions complies with this covenant and that such Affiliate Transaction or series of related Affiliate Transactions has been approved by a majority of the Disinterested Members; and

(b) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $150 million or 3% of Consolidated Total Assets, an opinion issued by an independent accounting, appraisal or investment banking firm of national standing stating that such Affiliate Transaction or series of related Affiliate Transactions is fair to the Company or such Restricted Subsidiary from a financial point of view.

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

(2) Restricted Payments that are permitted by the provisions of the 2023 Indenture described above under “—Certain Covenants—Limitation on Restricted Payments” and Permitted Investments;

(3) any issuance or sale of Equity Interests (other than Disqualified Stock) of the Company;

(4) transactions pursuant to agreements or arrangements in effect on the Issue Date and described in the Offering Memorandum, or any amendment, modification, or supplement thereto or renewal or replacement thereof, as long as such agreement or arrangement, as so amended, modified, supplemented, renewed or replaced, taken as a whole, is not materially more disadvantageous to the Company and the Restricted Subsidiaries than the agreement or arrangement in existence on the Issue Date as determined by the Disinterested Members of the Board of Directors of the Company evidenced by a Board Resolution;

(5) payments by the Company (and any direct or indirect parent thereof) and its Subsidiaries pursuant to tax sharing agreements among the Company (and any such parent) and its Subsidiaries on customary terms to the extent attributable to the ownership or operation of the Company and its Subsidiaries; provided that in each case the amount of such payments in any fiscal year does not exceed the amount that the Company, its Restricted Subsidiaries and its Unrestricted Subsidiaries (to the extent of amounts received from Unrestricted Subsidiaries) would be required to pay in respect of foreign, federal, state and local taxes for such fiscal year were the Company and its Subsidiaries (to the extent described above) to pay such taxes separately from any such parent entity;

(6) payment of reasonable and customary fees to, and reasonable and customary indemnification arrangements and similar payments on behalf of, directors of the Company or any Subsidiary thereof; and

(7) any employment, consulting, service or termination agreement, or reasonable and customary indemnification arrangements, entered into by the Company or any Restricted Subsidiary with officers and employees of the Company or any Subsidiary thereof and the payment of compensation to officers and employees of the Company or any Subsidiary thereof (including amounts paid pursuant to employee benefit plans, employee stock option or similar plans), so long as such agreement or payment have been approved by a majority of the Disinterested Members.

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

(1) the Company or such Restricted Subsidiary, as applicable, could have (a) Incurred Indebtedness in an amount equal to the Attributable Debt relating to such Sale and Leaseback Transaction and (b) incurred a Lien to secure such Indebtedness pursuant to the covenant described above under “—Certain Covenants—Limitation on Liens”;

(2) the gross cash proceeds of that Sale and Leaseback Transaction are at least equal to the Fair Market Value of the property that is the subject of that Sale and Leaseback Transaction; and

(3) the transfer of assets in that Sale and Leaseback Transaction is permitted by, and the Company applies the proceeds of such transaction in compliance with, the covenant described above under “—Repurchase at the Option of Holders—Asset Sales.”

The Board of Directors of the Company may designate any Restricted Subsidiary to be an Unrestricted Subsidiary; provided that:

(1) any Guarantee by the Company or any Restricted Subsidiary of any Indebtedness of the Subsidiary being so designated will be deemed to be an Incurrence of Indebtedness by the Company or such Restricted Subsidiary, as the case may be, at the time of such designation, and such Incurrence of Indebtedness would be permitted under the covenant described above under “—Certain Covenants—Limitation on Indebtedness”;

(2) the aggregate Fair Market Value of all outstanding Investments owned by the Company and the Restricted Subsidiaries in the Subsidiary being so designated (including any Guarantee by the Company or any Restricted Subsidiary of any Indebtedness of such Subsidiary) will be deemed to be an Investment made as of the time of such designation and that such Investment would be permitted under the covenant described above under “—Certain Covenants—Limitation on Restricted Payments”;

(3) such Subsidiary does not hold any Capital Stock or Indebtedness of, or own or hold any Lien on any property or assets of, or have any Investment in, the Company or any Restricted Subsidiary;

(a) is not party to any agreement, contract, arrangement or understanding with the Company or any Restricted Subsidiary unless the terms of any such agreement, contract, arrangement or understanding are no less favorable to the Company or such Restricted Subsidiary than those that might be obtained at the time from Persons who are not Affiliates of the Company;

(b) is a Person with respect to which neither the Company nor any Restricted Subsidiary has any direct or indirect obligation (i) to subscribe for additional Equity Interests or (ii) to maintain or preserve such Person’s financial condition or to cause such Person to achieve any specified levels of operating results; and

(c) has not Guaranteed or otherwise directly or indirectly provided credit support for any Indebtedness of the Company or any Restricted Subsidiary, except to the extent such Guarantee or credit support would be released upon such designation; and

(5) no Default or Event of Default would be in existence following such designation.

Any designation of a Restricted Subsidiary as an Unrestricted Subsidiary will be evidenced to the Trustee by filing with the Trustee the Board Resolution giving effect to such designation and an Officers’ Certificate and an Opinion of Counsel certifying that such designation complied with the preceding conditions and was permitted by the 2023 Indenture. If, at any time, any Unrestricted Subsidiary (x) would fail to meet any of the preceding requirements described in clause (4) above, it will thereafter cease to be an Unrestricted Subsidiary for purposes of the 2023 Indenture, and any Indebtedness, Investments, or Liens on the property, of such Subsidiary will be deemed to be Incurred or made by a Restricted Subsidiary as of such date, and if such Indebtedness, Investments or Liens are not permitted to be Incurred or made as of such date under the 2023 Indenture, the Issuers will be in default under the 2023 Indenture.

The Board of Directors of the Company may at any time designate any Unrestricted Subsidiary to be a Restricted Subsidiary; provided that:

(1) such designation will be deemed to be an Incurrence of Indebtedness by a Restricted Subsidiary of any outstanding Indebtedness of such Unrestricted Subsidiary and such designation will only be permitted if such Indebtedness is permitted under the covenant described above under “—Certain Covenants—Limitation on Indebtedness”;

(2) all outstanding Investments owned by such Unrestricted Subsidiary will be deemed to be made as of the time of such designation and such designation will only be permitted if such Investments would be permitted under the covenant described above under “—Certain Covenants—Limitation on Restricted Payments”;

(3) all Liens upon property or assets of such Unrestricted Subsidiary existing at the time of such designation would be permitted under the covenant described above under “—Certain Covenants—Limitation on Liens”; and

(4) no Default or Event of Default would be in existence following such designation.

If the Company or any Restricted Subsidiary acquires or creates another Domestic Subsidiary on or after the Issue Date, then that newly acquired or created Domestic Subsidiary must become a Guarantor and (i) execute a supplemental indenture and (ii) deliver an Opinion of Counsel to the Trustee. The ability of any future Domestic Subsidiary to become a Guarantor may be subject to prior approval by certain State PUCs.

The Company will not permit any Restricted Subsidiary, directly or indirectly, to Guarantee any Indebtedness of the Issuers or any Guarantor unless such Restricted Subsidiary (a) is a Guarantor or (b) within ten days executes and delivers to the Trustee an Opinion of Counsel and a supplemental indenture providing for the Guarantee of the payment of the 2023 Notes by such Restricted Subsidiary, which Guarantee will rank senior in right of payment to or equally in right of payment with such Subsidiary’s Guarantee of such other Indebtedness.

The Company will not, and will not permit any Restricted Subsidiary to, engage in any business other than Permitted Businesses, except to such extent as would not be material to the Company and the Restricted Subsidiaries taken as a whole.

The Company will not, and will not permit any Restricted Subsidiary to, directly or indirectly, pay or cause to be paid any consideration to or for the benefit of any Holder of 2023 Notes for or as an inducement to any consent, waiver or amendment of any of the terms or provisions of the 2023 Indenture or the 2023 Notes unless such consideration is offered to be paid to all Holders that may legally participate in the transaction, in the structure proposed by the Company, and is paid to all such Holders of the 2023 Notes that consent, waive or agree to amend in the time frame and in the manner set forth in the solicitation documents relating to such consent, waiver or agreement.

The Issuers will (i) furnish to the Trustee, (ii) upon request, furnish to beneficial owners and prospective investors and (iii) prior to the consummation of the Exchange Offer, make publicly available on its website, a copy of all of the information and reports referred to in clauses (1) and (2) below within the time periods specified in the Commission’s rules and regulations:

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

(2) all current reports that would be required to be filed with the Commission on Form 8-K if the Issuers were required to file such reports.

After consummation of the Exchange Offer contemplated by the Registration Rights Agreement, whether or not required by the Commission, the Issuers will comply with the periodic reporting requirements of the Exchange Act and will file the reports specified in the preceding paragraph with the Commission within the time periods specified above unless the Commission will not accept such a filing. The Issuers will not take any action for the purpose of causing the Commission not to accept any such filings. If, notwithstanding the foregoing, the Commission will not accept any Issuer’s filings for any reason, such Issuer will post the reports referred to in the preceding paragraph on its website within the time periods that would apply if such Issuer were required to file those reports with the Commission.

If the Company has designated as Unrestricted Subsidiaries any of its Subsidiaries that is a Significant Subsidiary or that, when taken together with all other Unrestricted Subsidiaries, would be a Significant Subsidiary, then the quarterly and annual financial information required by this covenant will include a reasonably detailed presentation, either on the face of the financial statements or in the footnotes thereto, and in “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” of the financial condition and results of operations of the Company and the Restricted Subsidiaries separate from the financial condition and results of operations of the Unrestricted Subsidiaries.

Notwithstanding the foregoing, if any parent of the Company becomes a Guarantor, the reports, information and other documents required to be filed and provided as described above may be those of the parent, rather than those of the Company, so long as such filings would satisfy the Commission’s requirements.

In addition, the Issuers and the Guarantors have agreed that, for so long as any 2023 Notes remain outstanding, they will furnish to the Holders and to prospective investors, upon their request, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act.

(2) default in payment when due (whether at maturity, upon acceleration, redemption or otherwise) of the principal of, or premium, if any, on the 2023 Notes;

(3) failure by the Company or any Restricted Subsidiary to make or consummate an Offer to Purchase in accordance with the provisions described above under “—Repurchase at the Option of Holders—Change of Control,” “—Repurchase at the Option of Holders—Asset Sales” or to comply with the provisions described above under “—Certain Covenants—Merger, Consolidation or Sale of Assets”;

(4) failure by the Company or any Restricted Subsidiary for 60 days after written notice by the Trustee or Holders representing 25% or more of the aggregate principal amount of 2023 Notes outstanding to comply with any of the other agreements in the 2023 Indenture;

(5) default under any mortgage, indenture or instrument under which there may be issued or by which there may be secured or evidenced any Indebtedness by the Company or any Restricted Subsidiary (or the payment of which is Guaranteed by the Company or any Restricted Subsidiary) whether such Indebtedness or Guarantee now exists, or is created after the Issue Date, if that default:

(a) is caused by a failure to make any payment when due at the final maturity of such Indebtedness (a “Payment Default”); or

(b) results in the acceleration of such Indebtedness prior to its express maturity;

and, in each case, the amount of any such Indebtedness, together with the amount of any other such Indebtedness that is then subject to a Payment Default or the maturity of which has been so accelerated, aggregates $50 million or more;

(6) failure by the Company or any Restricted Subsidiary to pay final judgments (to the extent such judgments are not paid or covered by insurance provided by a reputable and solvent carrier) aggregating in excess of $50 million, which judgments are not paid, discharged or stayed for a period of 90 days;

(7) except as permitted by the 2023 Indenture, any 2023 Note Guarantee is held in any judicial proceeding to be unenforceable or invalid or ceases for any reason to be in full force and effect or any Guarantor, or any Person acting on behalf of any Guarantor, denies or disaffirms its obligations under its 2023 Note Guarantee; and

(8) certain events of bankruptcy or insolvency with respect to the Company, any Guarantor or any Restricted Subsidiary that is a Significant Subsidiary of the Company (or any Restricted Subsidiaries that together would constitute a Significant Subsidiary of the Company).

In the case of an Event of Default described in clause (8) above, all outstanding 2023 Notes will become due and payable immediately without further action or notice. If any other Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in principal amount of the then-outstanding 2023 Notes may declare all the 2023 Notes to be due and payable immediately by notice in writing to the Company specifying the Event of Default.

Holders of the 2023 Notes may not enforce the 2023 Indenture or the 2023 Notes except as provided in the 2023 Indenture. Subject to certain limitations, Holders of a majority in principal amount of the then-outstanding 2023 Notes may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders of the 2023 Notes notice of any Default or Event of Default (except a Default or Event of Default relating to the payment of principal or interest) if it determines that withholding notice is in their interest.

The Holders of a majority in aggregate principal amount of the 2023 Notes then outstanding by notice to the Trustee may on behalf of the Holders of all of the 2023 Notes waive any existing Default or Event of Default and its consequences under the 2023 Indenture except a continuing Default or Event of Default in the payment of premium, or interest, or the principal of, the 2023 Notes. However, the Trustee may refuse to follow any direction that conflicts with law or the 2023 Indenture, that may involve the Trustee’s personal liability, or that the Trustee determines in good faith may be unduly prejudicial to the rights of Holders of 2023 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 2023 Notes. A Holder may not pursue any remedy with respect to the 2023 Indenture or the 2023 Notes unless:

(1) the Holder gives the Trustee written notice of a continuing Event of Default;

(2) the Holders of at least 25% in aggregate principal amount of outstanding 2023 Notes make a written request to the Trustee to pursue the remedy;

(3) such Holder or Holders offer the Trustee indemnity reasonably satisfactory to the Trustee against any costs, liability or expense;

(4) the Trustee does not comply with the request within 60 days after receipt of the request and the offer of indemnity; and

(5) during such 60-day period, the Holders of a majority in aggregate principal amount of the outstanding 2023 Notes do not give the Trustee a direction that is inconsistent with the request.

However, such limitations do not apply to the right of any Holder of a 2023 Note to receive payment of the principal of, premium, if any, or interest on, such 2023 Note or to bring suit for the enforcement of any such payment, on or after the due date expressed in the 2023 Notes, which right will not be impaired or affected without the consent of the Holder.

The Company is required to deliver to the Trustee annually within 90 days after the end of each fiscal year a statement regarding compliance with the 2023 Indenture. Within five Business Days of becoming aware of any Default or Event of Default, the Company is required to deliver to the Trustee a statement specifying such Default or Event of Default.

No director, officer, employee, incorporator, stockholder, member, manager or partner of any Issuer or any Guarantor, as such, will have any liability for any obligations of the Company or the Guarantors under the 2023 Notes, the 2023 Indenture, or the 2023 Note Guarantees, or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder of 2023 Notes, by accepting a 2023 Note, waives and releases all such liability. The waiver and release are part of the consideration for issuance of the 2023 Notes. The waiver may not be effective to waive liabilities under the federal securities laws.

The Issuers may, at their option and at any time, elect to have all of its obligations discharged with respect to the outstanding 2023 Notes and all obligations of the Guarantors discharged with respect to their 2023 Note Guarantees (“Legal Defeasance”) except for:

(1) the rights of Holders of outstanding 2023 Notes to receive payments in respect of the principal of, or interest or premium, if any, on such 2023 Notes when such payments are due from the trust referred to below;

(2) the Issuers’ obligations with respect to the 2023 Notes concerning issuing temporary 2023 Notes, registration of 2023 Notes, mutilated, destroyed, lost or stolen 2023 Notes and the maintenance of an office or agency for payment and money for security payments held in trust;

(3) the rights, powers, trusts, duties and immunities of the Trustee, and the Issuers’ and the Guarantors’ obligations in connection therewith; and

In addition, the Issuers may, at their option and at any time, elect to have the obligations of the Issuers and the Guarantors released with respect to certain covenants in the 2023 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 2023 Notes. In the event Covenant Defeasance occurs, certain events (not including non-payment, bankruptcy, receivership, rehabilitation and insolvency events) described under “—Events of Default and Remedies” will no longer constitute Events of Default with respect to the 2023 Notes.

(1) the Company must irrevocably deposit with the Trustee, in trust, for the benefit of the Holders of the 2023 Notes, cash in U.S. dollars, non-callable Government Securities, or a combination thereof, in such amounts as will be sufficient, in the opinion of a nationally recognized firm of independent public accountants, to pay the principal of, and interest and premium, if any, on the outstanding 2023 Notes on the Stated Maturity or on the applicable redemption date, as the case may be, and the Issuers must specify whether the 2023 Notes are being defeased to maturity or to a particular redemption date;

(2) in the case of Legal Defeasance, the Issuers will have delivered to the Trustee an Opinion of Counsel reasonably acceptable to the Trustee confirming that (a) the Issuers have received from, or there has been published by, the Internal Revenue Service a ruling or (b) since the Issue Date, there has been a change in the applicable federal income tax law, in either case to the effect that, and based thereon such Opinion of Counsel will confirm that, the Holders of the outstanding 2023 Notes will not recognize income, gain or loss for federal income tax purposes as a result of such Legal Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Legal Defeasance had not occurred;

will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred;

(4) no Default or Event of Default will have occurred and be continuing either (a) on the date of such deposit; or (b) insofar as Events of Default from bankruptcy or insolvency events are concerned, at any time in the period ending on the 91st day after the date of deposit;

(5) such Legal Defeasance or Covenant Defeasance will not result in a breach or violation of, or constitute a default under, any material agreement or instrument to which the Company or any of its Subsidiaries is a party or by which the Company or any of its Subsidiaries is bound;

(6) the Issuers must have delivered to the Trustee an Opinion of Counsel to the effect that, assuming no intervening bankruptcy of any Issuers or any Guarantor between the date of deposit and the 91st day following the deposit and assuming that no Holder is an “insider” of any Issuer under applicable bankruptcy law, after the 91st day following the deposit, the trust funds will not be subject to the effect of any applicable bankruptcy, insolvency, reorganization or similar laws affecting creditors’ rights generally, including Section 547 of the United States Bankruptcy Code and Section 15 of the New York Debtor and Creditor Law;

(7) the Issuers must deliver to the Trustee an Officers’ Certificate stating that the deposit was not made by the Issuers with the intent of preferring the Holders over the other creditors of the Issuers with the intent of defeating, hindering, delaying or defrauding creditors of the Issuers or others;

(8) if the 2023 Notes are to be redeemed prior to their Stated Maturity, the Issuers must deliver to the Trustee irrevocable instructions to redeem all of the 2023 Notes on the specified redemption date under arrangements satisfactory to the Trustee for the giving of notice of such redemption by the Trustee in the Issuers’ names and at the Issuers’ expense; and

(9) the Company must deliver to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent relating to the Legal Defeasance or the Covenant Defeasance, as applicable, have been complied with.

The 2023 Indenture will be discharged and will cease to be of further effect as to all 2023 Notes issued thereunder, when:

(a) all 2023 Notes that have been authenticated (except lost, stolen or destroyed 2023 Notes that have been replaced or paid and 2023 Notes for whose payment money has theretofore been deposited in trust and thereafter repaid to the Issuers) have been delivered to the Trustee for cancellation; or

(b) all 2023 Notes that have not been delivered to the Trustee for cancellation (x) have become due and payable (by reason of the mailing of a notice of redemption or otherwise), (y) will become due and payable at Stated Maturity within one year or (z) are to be called for redemption within one year under arrangements satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the Issuers’ names and at the Issuer’s expense, and in each such case the Issuers have irrevocably deposited or caused to be deposited with the Trustee as trust funds in trust solely for the benefit of the Holders of the 2023 Notes, cash in U.S. dollars, non-callable Government Securities, or a combination thereof, in such amounts as will be sufficient, in the opinion of a nationally recognized firm of independent public accountants, without consideration of any reinvestment of interest, to pay and discharge the entire indebtedness on the 2023 Notes not delivered to the Trustee for cancellation for principal, premium, if any, and accrued interest to the Stated Maturity or redemption date, as the case may be;

default under, any other instrument to which any Issuer or any Guarantor is a party or by which the any Issuer or any Guarantor is bound;

(3) any Issuer or any Guarantor has paid or caused to be paid all sums payable by it under the 2023 Indenture; and

(4) the Issuers have delivered irrevocable instructions to the Trustee under the 2023 Indenture to apply the deposited money toward the payment of the 2023 Notes at Stated Maturity or the redemption date, as the case may be.

In addition, the Issuers must deliver an Officers’ Certificate and an Opinion of Counsel to the Trustee stating that all conditions precedent to satisfaction and discharge have been satisfied.

Except as provided in the next two succeeding paragraphs, the 2023 Indenture and the 2023 Notes may be amended or supplemented with the consent of the Holders of at least a majority in principal amount of the 2023 Notes then outstanding (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, 2023 Notes), and any existing default or compliance with any provision of the 2023 Indenture and the 2023 Notes may be waived with the consent of the Holders of a majority in principal amount of the then-outstanding 2023 Notes (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, 2023 Notes).

Without the consent of each Holder affected, an amendment or waiver may not (with respect to any 2023 Notes held by a non-consenting Holder):

(1) reduce the principal amount of 2023 Notes whose Holders must consent to an amendment, supplement or waiver;

(2) change the Stated Maturity of the principal of, or any installment of interest on, any 2023 Note;

(3) reduce the principal amount of, or premium, if any, or interest on, any 2023 Note;

(4) change the optional redemption dates or optional redemption prices of the 2023 Notes from those stated under “—Optional Redemption”;

(5) waive a Default or Event of Default in the payment of principal of, or interest, or premium, if any, on, the 2023 Notes (except, upon a rescission of acceleration of the 2023 Notes by the Holders of at least a majority in aggregate principal amount of the 2023 Notes, a waiver of the payment default that resulted from such acceleration) or in respect of any other covenant or provision that cannot be amended or modified without the consent of all Holders;

(7) make any change in the amendment and waiver provisions of the 2023 Indenture;

(8) release any Guarantor from any of its obligations under its 2023 Note Guarantee or the 2023 Indenture, except in accordance with the terms of the 2023 Indenture;

(9) impair the right to institute suit for the enforcement of any payment on or with respect to the 2023 Notes or the 2023 Note Guarantees;

(10) amend, change or modify the obligation of the Company to make and consummate an Offer to Purchase with respect to any Asset Sale in accordance with the covenant described above under “—Repurchase at the Option of Holders—Asset Sales” after the obligation to make such Offer to Purchase has arisen, or the obligation of the Issuers to make and consummate an Offer to Purchase in the event of a Change of Control in accordance with the covenant described above under “—Repurchase at the Option of

Holders—Change of Control” after such Change of Control has occurred, including, in each case, amending, changing or modifying any definition relating thereto;

(11) except as otherwise permitted under the covenants described above under “—Certain Covenants Merger, Consolidation or Sale of Assets” and “—Certain Covenants—Future Subsidiary 2023 Note Guarantees,” consent to the assignment or transfer by any Issuers or any Guarantor of any of their rights or obligations under the 2023 Indenture.

Notwithstanding the preceding, without the consent of any Holder of 2023 Notes, the Issuers, the Guarantors and the Trustee may amend or supplement the 2023 Indenture or the 2023 Notes:

(1) to cure any provision determined by the Board of Directors of the Company in good faith, evidenced by a Board Resolution, to be an ambiguity, defect or inconsistency;

(2) to provide for uncertificated 2023 Notes in addition to or in place of certificated 2023 Notes;

(3) to provide for the assumption of any Issuer’s or any Guarantor’s obligations to Holders of 2023 Notes in accordance with the 2023 Indenture in the case of a merger or consolidation or sale of all or substantially all of such Issuer’s or such Guarantor’s assets;

(4) to make any change that would provide any additional rights or benefits to the Holders of 2023 Notes or that does not materially, in the good faith determination of the Board of Directors of the Company, evidenced by a Board Resolution, adversely affect the legal rights under the 2023 Indenture of any such Holder;

(5) to comply with requirements of the Commission in order to effect or maintain the qualification of the 2023 Indenture under the Trust Indenture Act;

(6) to comply with the provisions described above under “—Certain Covenants—Future Subsidiary 2023 Note Guarantees”;

(7) to evidence and provide for the acceptance of appointment by a successor Trustee;

(8) to provide for the issuance of Additional 2023 Notes in accordance with the 2023 Indenture; or

(9) to conform the 2023 Indenture or the 2023 Notes to any provision of this “Description of the 2023 Notes” to the extent such provision is intended to be a verbatim recitation thereof.

If the Trustee becomes a creditor of any Issuer or any Guarantor, the 2023 Indenture and the Trust Indenture Act limit its right to obtain payment of claims in certain cases, or to realize on certain property received in respect of any such claim as security or otherwise. The Trustee will be permitted to engage in other transactions; provided that if it acquires any conflicting interest, it must eliminate such conflict within 90 days, apply to the Commission for permission to continue, or resign.

The 2023 Indenture provides that in case an Event of Default occurs and is continuing, the Trustee will be required, in the exercise of its power, to use the degree of care of a prudent man in the conduct of his own affairs. Subject to such provisions, the Trustee will be under no obligation to exercise any of its rights or powers under the 2023 Indenture at the request of any Holder of 2023 Notes, unless such Holder will have offered to the Trustee security and indemnity satisfactory to it against any loss, liability or expense.

Except as set forth below, 2023 Notes will be issued in registered, global form in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof. The 2023 Notes will be issued at the closing of this offering only against payment in immediately available funds.

2023 Notes initially will be represented by one or more notes in registered, global form without interest coupons (collectively, the “2023 Global Notes”). The 2023 Global Notes will be deposited upon issuance with the Trustee as custodian for DTC and registered in the name of DTC or its nominee, in each case for credit to an account of a direct or indirect participant in DTC as described below. Beneficial interest in the 2023 Global Notes may be held only through Euroclear Bank, S.A./N.V as operator of the Euroclear System (“Euroclear”) and Clearstream Banking, S.A. (“Clearstream”) (as indirect participants in DTC).

Except as set forth below, the 2023 Global Notes may be transferred, in whole and not in part, only to another nominee of DTC or to a successor of DTC or its nominee. Beneficial interests in the 2023 Global Notes may be exchanged for 2023 Notes in certificated form. See “—Exchange of 2023 Global Notes for Certificated 2023 Notes.”

In addition, transfers of beneficial interests in the Global Notes will be subject to the applicable rules and procedures of DTC and its direct or indirect participants (including, if applicable, those of Euroclear and Clearstream), which may change from time to time.

The following description of the operations and procedures of DTC, Euroclear and Clearstream are provided solely as a matter of convenience. These operations and procedures are solely within the control of the respective settlement systems and are subject to changes by them. The Issuers take no responsibility for these operations and procedures and urges investors to contact the system or their participants directly to discuss these matters.

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

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

(1) upon deposit of the Global Notes, DTC will credit the accounts of Participants designated by the Initial Purchasers with portions of the principal amount of the Global Notes; and

(2) ownership of these interests in the Global Notes will be shown on, and the transfer of ownership thereof will be effected only through, records maintained by DTC (with respect to the Participants) or by the Participants and the Indirect Participants (with respect to other owners of beneficial interest in the Global Notes).

Investors in the 2023 Global Notes who are Participants in DTC’s system may hold their interests therein directly through DTC. Investors in the 2023 Global Notes who are not Participants may hold their interests therein indirectly through organizations (including Euroclear and Clearstream) which are Participants in such system. Euroclear and Clearstream will hold interests in the Regulation S Global Notes on behalf of their participants through customers’ securities accounts in their respective names on the books of their respective depositories, which are Euroclear Bank, S.A./N.V., as operator of Euroclear, and Citibank, N.A., as operator of Clearstream. All interests in a Global Note, including those held through Euroclear or Clearstream, may be subject to the procedures and requirements of DTC. Those interests held through Euroclear or Clearstream may also be subject to the procedures and requirements of such systems.

Except as described below, owners of interests in the Global Notes will not have notes registered in their names, will not receive physical delivery of notes in certificated form and will not be considered the registered owners or “Holders” thereof under the 2023 Indenture for any purpose.

Payments in respect of the principal of, and interest and premium, if any, on a Global Note registered in the name of DTC or its nominee will be payable to DTC in its capacity as the registered Holder under the 2023 Indenture. Under the terms of the 2023 Indenture, the Issuers and the Trustee will treat the Persons in whose names the 2023 Notes, including the 2023 Global Notes, are registered as the owners thereof for the purpose of receiving payments and for all other purposes. Consequently, neither the Issuers, the Trustee nor any agent of the Issuers or the Trustee has or will have any responsibility or liability for:

(1) any aspect of DTC’s records or any Participant’s or Indirect Participant’s records relating to or payments made on account of beneficial ownership interest in the Global 2023 Notes or for maintaining, supervising or reviewing any of DTC’s records or any Participant’s or Indirect Participant’s records relating to the beneficial ownership interests in the Global 2023 Notes; or

(2) any other matter relating to the actions and practices of DTC or any of its Participants or Indirect Participants.

DTC has advised the Issuers that its current practice, upon receipt of any payment in respect of securities such as the 2023 Notes (including principal and interest), is to credit the accounts of the relevant Participants with the payment on the payment date unless DTC has reason to believe it will not receive payment on such payment date. Each relevant Participant is credited with an amount proportionate to its beneficial ownership of an interest in the principal amount of the relevant security as shown on the records of DTC. Payments by the Participants and the Indirect Participants to the beneficial owners of 2023 Notes will be governed by standing instructions and customary practices and will be the responsibility of the Participants or the Indirect Participants and will not be the responsibility of DTC, the Trustee or the Issuers. Neither the Issuers nor the Trustee will be liable for any delay by DTC or any of its Participants in identifying the beneficial owners of the 2023 Notes, and the Issuers and the Trustee may conclusively rely on and will be protected in relying on instructions from DTC or its nominee for all purposes.

Transfers between Participants in DTC will be effected in accordance with DTC’s procedures, and will be settled in same-day funds, and transfers between participants in Euroclear and Clearstream will be effected in accordance with their respective rules and operating procedures.

Cross-market transfers between the Participants 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 counterparty in such system in accordance with the rules and procedures and within the established deadlines (Brussels time) of such system. Euroclear or Clearstream, as the case may be, will, if the transaction meets its settlement requirements, deliver instructions to its respective depositary to take action to effect final settlement on its behalf by delivering or receiving interests in the relevant Global Note in DTC, and making or receiving payment in accordance with normal procedures for same-day funds settlement applicable to DTC. Euroclear participants and Clearstream participants may not deliver instructions directly to the depositories for Euroclear or Clearstream.

DTC has advised the Issuers that it will take any action permitted to be taken by a Holder of 2023 Notes only at the direction of one or more Participants to whose account DTC has credited the interests in the Global 2023 Notes and only in respect of such portion of the aggregate principal amount of the 2023 Notes as to which such Participant or Participants has or have given such direction. However, if there is an Event of Default under the 2023 Notes, DTC reserves the right to exchange the 2023 Global Notes for legended notes in certificated form, and to distribute such notes to its Participants.

Although DTC, Euroclear and Clearstream have agreed to the foregoing procedures to facilitate transfers of interests in the 2023 Global Notes among participants in DTC, Euroclear and Clearstream, they are under no obligation to perform or to continue to perform such procedures, and may discontinue such procedures at any time. Neither the Issuers nor the Trustee nor any of their respective agents will have any responsibility for the performance by DTC, Euroclear or Clearstream or their respective participants or indirect participants of their respective obligations under the rules and procedures governing their operations.

A 2023 Global Note is exchangeable for definitive notes in registered certificated form (“Certificated 2023 Notes”) if:

(1) DTC (a) notifies the Issuers that it is unwilling or unable to continue as depositary for the 2023 Global Notes or (b) has ceased to be a clearing agency registered under the Exchange Act, and in each case the Issuers fail to appoint a successor depositary;

(2) the Issuers, at their option, notify the Trustee in writing that they elect to cause the issuance of Certificated 2023 Notes (DTC has advised the Issuers that, in such event, under its current practices, DTC would notify its participants of the Issuers’ request, but will only withdraw beneficial interests from a Global Note at the request of each DTC participant); or

(3) there will have occurred and be continuing a Default or Event of Default with respect to the 2023 Notes.

In addition, beneficial interests in a Global Note may be exchanged for Certificated 2023 Notes upon prior written notice given to the Trustee by or on behalf of DTC in accordance with the 2023 Indenture. In all cases, Certificated 2023 Notes delivered in exchange for any 2023 Global Note or beneficial interests in 2023 Global Notes will be registered in the names, and issued in any approved denominations, requested by or on behalf of the depositary (in accordance with its customary procedures).

Certificated Notes may not be exchanged for beneficial interests in any Global Note.

The Issuers will make payments in respect of the 2023 Notes represented by the 2023 Global Notes (including principal, premium, if any, interest) by wire transfer of immediately available funds to the accounts specified by the Global Note Holder. The Issuers will make all payments of principal, interest and premium, if any, with respect to Certificated 2023 Notes by wire transfer of immediately available funds to the accounts specified by the Holders thereof or, if no such account is specified, by mailing a check to each such Holder’s registered address. The 2023 Notes represented by the 2023 Global Notes are expected to trade in DTC’s Same-Day Funds Settlement System, and any permitted secondary market trading activity in such 2023 Notes will, therefore, be required by DTC to be settled in immediately available funds. The Issuers expect that secondary trading in any Certificated 2023 Notes will also be settled in immediately available funds.

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

Such present value will be calculated using a discount rate equal to the rate of interest implicit in such transaction, determined in accordance with GAAP.

“Beneficial Owner” has the meaning assigned to such term in Rule 13d-3 and Rule 13d-5 under the Exchange Act, except that in calculating the beneficial ownership of any particular “person” (as that term is used in Section 13(d)(3) of the Exchange Act), such “person” will be deemed to have beneficial ownership of all securities that such “person” has the right to acquire by conversion or exercise of other securities, whether such right is currently exercisable or is exercisable only upon the occurrence of a subsequent condition. The terms “Beneficially Owns” and “Beneficially Owned” will have correlative meanings.

The 2025 Outstanding Notes were issued in a private transaction that was not subject to the registration requirements of the Securities Act and are referred to collectively herein as the “Outstanding Notes.”

Brief Description of the Structure and Ranking of the 2025 Notes and the 2025 Note Guarantees

As of June 30, 2015 and after excluding intercompany balances and intercompany guarantees:

As of the date of this prospectus, none of the Company’s Foreign Subsidiaries and Zayo Capital, Inc., the co-issuer, guarantee the 2025 Notes. For the year ended June 30, 2015, the non-guarantor Subsidiaries of the Company (other than Zayo Capital, Inc.) generated 12% of the Company’s consolidated net revenue and 10% of the Company’s consolidated Adjusted EBITDA. In addition, as of June 30, 2015, these non-guarantor Subsidiaries of the Company held 13% of the Company’s total consolidated assets and had $151.3 million in liabilities (excluding inter-company liabilities). In addition, the 2025 Indenture will not require any future Foreign Subsidiaries of the Company to guarantee the 2025 Notes unless they guarantee other Indebtedness of the Issuers. In the event of a bankruptcy, liquidation or reorganization of any non-guarantor Subsidiaries, the non-guarantor Subsidiaries will likely be required to repay financial and trade creditors before distributing any assets to the Issuers or a Guarantor.

As of the date of this prospectus, all of the Company’s Subsidiaries (other than Zayo Capital, Inc., the co-issuer) are “Restricted Subsidiaries.” However, under the circumstances described below under “—Certain Covenants—Designation of Restricted and Unrestricted Subsidiaries,” the Company will be permitted to designate certain of its Subsidiaries as “Unrestricted Subsidiaries.” Unrestricted Subsidiaries will not be subject to any of the restrictive covenants in the 2025 Indenture. Further, Unrestricted Subsidiaries will not Guarantee the 2025 Notes.

Although the 2025 Indenture contains limitations on the amount of additional Indebtedness that the Issuers, the Guarantors and the Restricted Subsidiaries may incur, the amount of such additional Indebtedness could be substantial.

The 2025 Notes will mature on May 15, 2025. The Issuers will issue up to $350 million aggregate principal amount of 2025 Notes in this exchange offer. Subject to the covenant described under “—Certain Covenants—Limitation on Indebtedness,” the Issuers are permitted to issue additional notes under the 2025 Indenture (“Additional 2025 Notes”). The 2025 Notes and any Additional 2025 Notes that are issued will be treated as a single class under the 2025 Indenture, including with respect to waivers, amendments, redemptions and Offers to Purchase. The Additional 2025 Notes may be issued at different prices from the original issue price of the 2025 Notes in this offering. Unless the context otherwise requires, references to the “2025 Notes” for all purposes under the 2025 Indenture and in this “Description of 2025 Notes” include any Additional 2025 Notes that are issued.

Interest on the 2025 Notes will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from and including the Issue Date, at a rate per annum of 6.375%, and will be payable semiannually in arrears on May 15 and November 15 of each year. Interest will be payable to Holders of record on each Note in respect of the principal amount thereof outstanding as of the immediately preceding May 1 or November 1, as the case may be.

Interest will be computed on the basis of a 360-day year comprising twelve 30-day months. Interest on overdue principal and interest will accrue at a rate that is 2% higher than the then applicable interest rate on the 2025 Notes. In no event will the rate of interest on the 2025 Notes be higher than the maximum rate permitted by applicable law.

The 2025 Notes will be issued only in fully registered form without coupons and only in denominations of $2,000 and integral multiples of $1,000 in excess thereof.

The 2025 Notes will be initially in the form of one or more global notes (the “2025 Global Notes”). The 2025 Global Notes will be deposited with the Trustee as custodian for the Depository Trust Company (“DTC”). Ownership of interests in the 2025 Global Notes, referred to in this description as “book entry interests,” will be limited to Persons that have accounts with DTC or their respective participants. The terms of the 2025 Indenture will provide for the issuance of definitive registered 2025 Notes in certain circumstances. Please see the section entitled “—Book Entry, Delivery and Form.”

The registered Holder of a 2025 Note will be treated as the owner of it for all purposes.

A Holder may transfer or exchange 2025 Notes in accordance with the 2025 Indenture and the procedures described in “Notice to Investors.” The Registrar and the Trustee may require a Holder, among other things, to furnish appropriate endorsements and transfer documents. No service charge will be made for any registration of transfer, exchange or redemption of the 2025 Notes, but the Issuers may require payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection with any such registration of transfer or exchange.

The Issuers are not required to transfer or exchange any 2025 Note selected for redemption. Also, the Issuers are not required to transfer or exchange any 2025 Note for a period of 15 days before a selection of 2025 Notes to be redeemed.

If a Holder has given wire transfer instructions to the Company at least ten Business Days prior to the applicable payment date, the Company will pay all principal, interest and premium, if any, on that Holder’s 2025 Notes in accordance with those instructions. All other payments on 2025 Notes will be made at the office or agency of the Paying Agent and Registrar unless the Company elects to make interest payments by check mailed to the Holders at their addresses set forth in the register of Holders; provided that all payments of principal, premium, if any, and interest, with respect to the 2025 Global Notes registered in the name of or held by DTC or its nominee and will be made by wire transfer of immediately available funds to the account specified by DTC.

The Initial Guarantors jointly and severally guarantee the due and punctual payment of all amounts payable under the 2025 Notes, including principal, premium, if any, and interest. The 2025 Indenture requires any future Domestic Subsidiary, that is not designated as an Unrestricted Subsidiary, and any other Restricted Subsidiary that Guarantees Indebtedness of the Issuers or any Guarantor to provide a Note Guarantee. The ability of any future Domestic Subsidiaries to provide a Note Guarantee may be subject to prior approval by certain State PUCs. See “—Certain Covenants—Future Subsidiary 2025 Note Guarantees.”

Each 2025 Note Guarantee of a Guarantor is the Guarantor’s senior obligation. The 2025 Indenture states that each Guarantor under its 2025 Note Guarantee will be limited to an amount not to exceed the maximum amount that can be guaranteed by such Guarantor by law or without resulting in its obligations under its 2025 Note Guarantee being voidable or unenforceable under applicable laws relating to fraudulent transfer, or under similar laws affecting the rights of creditors generally. With respect to risks related to such limitations, see “Risk Factors—Risks Relating to the 2025 Notes—Federal and state statutes allow courts, under specific circumstances, to cancel the notes or the related guarantees and require noteholders to return payments received from us or the guarantors.” Each Guarantor that makes a payment or distribution under its 2025 Note Guarantee will be entitled to contribution from any other Guarantor.

A 2025 Note Guarantee of a Guarantor will be automatically and unconditionally released (and thereupon shall terminate and be discharged and be of no further force and effect):

(2) if the Company properly designates the Guarantor as an Unrestricted Subsidiary under the 2025 Indenture;

(3) solely in the case of a 2025 Note Guarantee created pursuant to the second paragraph of the covenant described below under “—Certain Covenants—Future Subsidiary 2025 Note Guarantees,” upon the release or discharge of the Guarantee that resulted in the creation of such 2025 Note Guarantee pursuant to that covenant, except a discharge or release by or as a result of payment under such 2025 Note Guarantee;

(4) upon a Legal Defeasance or satisfaction and discharge of the 2025 Indenture that complies with the provisions under “—Legal Defeasance and Covenant Defeasance” or “—Satisfaction and Discharge”; or

(5) upon payment in full of the aggregate principal amount of all 2025 Notes then outstanding and all other obligations under the 2025 Indenture and the 2025 Notes then due and owing.

Upon any occurrence giving rise to a release of a 2025 Note Guarantee as specified above, the Trustee will, at the written directions of the Company, execute any documents reasonably required in order to evidence or effect such release, termination and discharge in respect of such 2025 Note Guarantee. Neither the Issuers nor any Guarantor will be required to make a notation on the 2025 Notes to reflect any 2025 Note Guarantee or any such release, termination or discharge.

At any time prior to May 15, 2018, the Issuers may redeem up to 40% of the aggregate principal amount of 2025 Notes issued under the 2025 Indenture (including any Additional 2025 Notes) at a redemption price of 106.375% of the principal amount thereof, plus accrued and unpaid interest, if any, thereon to the redemption date, subject to the rights of Holders of 2025 Notes on the relevant record date to receive interest due on the relevant interest payment date, with the net cash proceeds of one or more Equity Offerings; provided that:

(1) at least 60% of the aggregate principal amount of 2025 Notes issued under the 2025 Indenture (including any Additional 2025 Notes) remains outstanding immediately after the occurrence of such redemption (excluding 2025 Notes held by the Issuers or their Affiliates); and

(2) the redemption must occur within 90 days of the date of the closing of such Equity Offering.

At any time prior to May 15, 2020, the Issuers may redeem all or part of the 2025 Notes at a redemption price equal to the sum of (i) 100% of the principal amount thereof, plus (ii) the Applicable Premium as of the date of redemption, plus (iii) accrued and unpaid interest, if any, to the date of redemption, subject to the rights of Holders of 2025 Notes on the relevant record date to receive interest due on the relevant interest payment date.

On or after May 15, 2020, the Issuers may redeem all or a part of the 2025 Notes, at the redemption prices (expressed as percentages of principal amount) set forth below plus accrued and unpaid interest, if any, thereon, to the applicable redemption date, subject to the rights of Holders of 2025 Notes on the relevant record date to receive interest due on the relevant interest payment date, if redeemed during the 12-month period beginning on May 15 of the years indicated below:

If less than all of the 2025 Notes are to be redeemed at any time, the 2025 Notes will be selected for redemption on a pro rata basis, by lot or by such other method as the Trustee deems fair and appropriate; provided, however that so long as the 2025 Notes are held through DTC, the 2025 Notes selected for redemption shall be selected in accordance with the applicable procedures of DTC.

No 2025 Notes of $2,000 or less will be redeemed in part. Notices of redemption will be delivered, at least 30 but not more than 60 days before the redemption date, to each Holder of 2025 Notes to be redeemed at its registered address. Notices of redemption may not be conditional.

If any 2025 Note is to be redeemed in part only, the notice of redemption that relates to that 2025 Note will state the portion of the principal amount thereof to be redeemed. A new 2025 Note in principal amount equal to

the unredeemed portion of the original 2025 Note will be issued in the name of the Holder thereof upon cancellation of the original 2025 Note. 2025 Notes called for redemption become due on the date fixed for redemption. On and after the redemption date, interest will cease to accrue on 2025 Notes or portions thereof called for redemption.

Unless the Issuers have previously or concurrently delivered a redemption notice with respect to all the outstanding 2025 Notes as described under “—Optional Redemption,” the Issuers must commence, within 30 days of the occurrence of a Change of Control, and consummate an Offer to Purchase for all 2025 Notes then outstanding, at a purchase price in cash equal to 101% of the aggregate principal amount of the 2025 Notes repurchased, plus accrued and unpaid interest, if any, thereon, to the date of repurchase, subject to the rights of Holders of 2025 Notes on the relevant record date to receive interest due on the relevant interest payment date.

The Issuers’ ability to pay cash to the Holders of the 2025 Notes following the occurrence of a Change of Control may be limited by the Issuers’ then-existing financial resources. Sufficient funds may not be available when necessary to make any required repurchases. See “Risk Factors—Risks Relating to the 2025 Notes—We may not be able to repurchase the notes upon a change of control or asset sale.”

The Change of Control purchase feature of the 2025 Notes may in certain circumstances make more difficult or discourage a sale or takeover of the Issuers and, thus, the removal of incumbent management. The Change of Control purchase feature is a result of negotiations between the Initial Purchasers and the Company. As of the date of this prospectus, the Issuers have no present intention to engage in a transaction involving a Change of Control, although it is possible that the Issuers could decide to do so in the future. Subject to the limitations discussed below, the Issuers could, in the future, enter into certain transactions, including acquisitions, refinancings or other recapitalizations, that would not constitute a Change of Control under the 2025 Indenture, but that could increase the amount of Indebtedness outstanding at such time or otherwise affect the Company’s capital structure or credit ratings. Restrictions on the Company’s ability to Incur additional Indebtedness are contained in the covenants described below under “—Certain Covenants—Limitation on Indebtedness.”

The Issuers 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 2025 Indenture applicable to an Offer to Purchase made by the Issuers and purchases all 2025 Notes validly tendered and not withdrawn under such Offer to Purchase.

If holders of not less than 90% in aggregate principal amount of the outstanding 2025 Notes validly tender and do not withdraw such notes in connection with an Offer to Purchase upon a Change of Control and the Company, or any third party making a Change of Control offer in lieu of the Company as described above, purchases all of the 2025 Notes validly tendered and not withdrawn by such holders, the Company or such third party will have the right, upon not less than 15 days nor more than 60 days’ prior notice, provided that such notice is given not more than 30 days following such purchase date, to redeem all 2025 Notes that remain outstanding following such purchase at a price equal to the price offered to each other holder in such tender offer plus accrued and unpaid interest, if any, to, but not including, the applicable redemption date.

The definition of Change of Control includes a phrase relating to the direct or indirect sale, transfer, conveyance or other disposition of “all or substantially all” of the properties or assets of the Company and the Restricted Subsidiaries taken as a whole. Although there is a limited body of case law interpreting the phrase “substantially all,” there is no precise established definition of the phrase under applicable law. Accordingly, the

ability of a Holder of 2025 Notes to require the Issuers to repurchase such 2025 Notes as a result of a sale, transfer, conveyance or other disposition of less than all of the assets of the Company and the Restricted Subsidiaries taken as a whole to another Person or group may be uncertain. See “Risk Factors—Risks Relating to the Notes—The ability of holders of notes to require us to repurchase notes as a result of a disposition of “substantially all” of our assets or a change in the composition of our board of directors is uncertain.”

The Company will not, and will not permit any Restricted Subsidiary to, consummate an Asset Sale unless:

(2) at least 75% of the consideration therefor received by the Company or such Restricted Subsidiary is in the form of:

The amount of such Net Available Cash required to be applied (or to be committed to be applied) during such 365-day period as set forth in the preceding paragraph and not applied (or committed to be applied) as so required by the end of such period, or used to consummate an Offer to Purchase pursuant to any indenture or similar document governing Permitted Additional Secured Obligations, shall constitute “Excess Proceeds.” If, as of the first day of any calendar month, the aggregate amount of Excess Proceeds totals at least $50 million, the Company must commence, not later than the 15th Business Day of such month, and consummate an Offer to Purchase, from the Holders and all holders of other Pari Passu Debt containing provisions similar to those set forth in the 2025 Indenture with respect to offers to purchase with the proceeds of sales of assets, the maximum principal amount of 2025 Notes and such other Pari Passu Debt that may be purchased out of the Excess Proceeds; provided that the amount of Excess Proceeds required to be used to make an Offer to Purchase pursuant to this paragraph shall be reduced by any mandatory prepayments made under any Series of Pari Passu Debt in respect of such Excess Proceeds (and which prepayments shall not be in excess of such Series pro rata share of such Excess Proceeds). The offer price in any such Offer to Purchase will be equal to 100% of the principal amount (or accreted value, if applicable) of the 2025 Notes and such other Pari Passu Debt plus accrued and unpaid interest, if any, to the date of purchase, subject to the rights of Holders of 2025 Notes on the relevant

record date to receive interest on the relevant interest payment date, and will be payable in cash. To the extent that any Excess Proceeds remain after consummation of an Offer to Purchase pursuant to this “—Repurchase at the Option of Holders Asset Sales” covenant, the Company may use those Excess Proceeds for any purpose not otherwise prohibited by the 2025 Indenture, and those Excess Proceeds shall no longer constitute “Excess Proceeds.”

For the purposes of this covenant, the following are deemed to be Cash Equivalents: the assumption of (i) Indebtedness of the Company (other than Disqualified Stock or Indebtedness that is by its terms subordinated in right of payment to the 2025 Notes); (ii) Indebtedness of any Restricted Subsidiary (other than Indebtedness of a Guarantor that is by its terms subordinated in right of payment to the 2025 Notes or Disqualified Stock of any Guarantor) or (iii) any liabilities (as shown on the Company’s or such Restricted Subsidiary’s most recent balance sheet) of the Company or any Restricted Subsidiary (other than contingent liabilities, Indebtedness that is by its terms subordinated to the 2025 Notes or any 2025 Note Guarantee and liabilities to the extent owed to the Company or any Subsidiary of the Company) and, in each case, the full and unconditional release of the Company or such Restricted Subsidiary from all liability on such Indebtedness in connection with such Asset Sale.

(a) the 2025 Notes have achieved an Investment Grade Rating from both of the Ratings Agencies; and

(b) no Default or Event of Default has occurred and is continuing under the 2025 Indenture,

then, beginning on that day and continuing until the Reversion Date (as defined below), the Company and its Restricted Subsidiaries will not be subject to the provisions of the 2025 Indenture summarized under the following headings (collectively, the “Suspended Covenants”):

If at any time the 2025 Notes cease to have such Investment Grade Rating by either Rating Agency or if a Default or Event of Default occurs and is continuing, then the Suspended Covenants will, from such date and thereafter be reinstated as if such covenants had never been suspended (the “Reversion Date”) and be applicable pursuant to the terms of the 2025 Indenture (including in connection with performing any calculation or assessment to determine compliance with the terms of the 2025 Indenture), unless and until the 2025 Notes subsequently attain an Investment Grade Rating from both Ratings Agencies and no Default or Event of Default is in existence (in which event the Suspended Covenants shall no longer be in effect for such time that the 2025 Notes maintain an Investment Grade Rating from both Ratings Agencies and no Default or Event of Default is in

existence); provided, however, that no Default, Event of Default or breach of any kind shall be deemed to exist under the 2025 Indenture, the 2025 Notes or the Guarantees with respect to the Suspended Covenants based on, and none of the Company or any of its Subsidiaries shall bear any liability for, any actions taken or events occurring during the Suspension Period (as defined below), or any actions taken at any time pursuant to any contractual obligation arising prior to the Reversion Date, regardless of whether such actions or events would have been permitted if the applicable Suspended Covenants remained in effect during such period. The period of time between the date of suspension of the covenants and the Reversion Date is referred to as the “Suspension Period.”

There can be no assurance that the 2025 Notes will ever achieve or maintain an Investment Grade Rating.

(A) The Company will not, and will not permit any Restricted Subsidiary to, directly or indirectly, take any of the following actions (each, a “Restricted Payment”):

(III) call for redemption or make any payment on or with respect to, or purchase, redeem, defease or otherwise acquire or retire for value, prior to the Stated Maturity thereof, any Indebtedness that is subordinated in right of payment to the 2025 Notes or any 2025 Note Guarantee except (a) in anticipation of satisfying a sinking fund obligation, principal installment or final maturity, in each case due within one year of the date of such payment, purchase, repurchase or other acquisition or (b) intercompany Indebtedness permitted to be Incurred pursuant to clause (6) of the second paragraph of the covenant described below under “—Certain Covenants—Limitation on Indebtedness”; or

(IV) make any Investment (other than a Permitted Investment) in any Person; unless, at the time of and after giving pro forma effect to such Restricted Payment:

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

As of June 30, 2015, we had at least $1,967 million available to make Restricted Payments under clause (3) of the immediately preceding paragraph above.

(1) the payment of any dividend within 60 days after the date of declaration thereof, if at said date of declaration such payment would have complied with the provisions of the 2025 Indenture, and the redemption of any Indebtedness that is subordinated in right of payment to the 2025 Notes or the 2025 Note Guarantees within 60 days after the date on which notice of such redemption was given, if at said date of the giving of such notice, such redemption would have complied with the provisions of the 2025 Indenture;

(2) the payment of any dividend or other distribution by a Restricted Subsidiary to all the holders of its Equity Interests on a pro rata basis;

(4) the redemption, repurchase, defeasance or other acquisition or retirement for value of Indebtedness that is subordinated in right of payment to the 2025 Notes or the 2025 Note Guarantees in exchange for or with the net cash proceeds from a substantially concurrent Incurrence (other than to a Subsidiary of the Company) of, Permitted Refinancing Indebtedness;

(10) other Restricted Payments in an aggregate amount not to exceed the greater of (i) $150 million and (ii) 3.0% of the Consolidated Total Assets;

(12) other Restricted Payments so long as, after giving pro forma effect to the payment of such Restricted Payment, the Consolidated Leverage Ratio would be positive and less than 3.75 to 1.00.

The first paragraph of this covenant will not prohibit the Incurrence of any of the following items of Indebtedness (collectively, “Permitted Indebtedness”):

(3) the Incurrence by the Company and the Guarantors of Indebtedness represented by the 2025 Notes (other than Additional 2025 Notes) and the related 2025 Note Guarantees;

(5) the Incurrence by the Company or any Restricted Subsidiary of Permitted Refinancing Indebtedness in exchange for, or the net cash proceeds of which are used to refund, refinance or replace Indebtedness that was permitted by the 2025 Indenture to be Incurred under the first paragraph of this covenant or clauses (2), (3), (5), (14) or (15) of this paragraph;

(6) the Incurrence by the Company or any Restricted Subsidiary of Indebtedness owing to and held by the Company or any Restricted Subsidiary; provided that:

(a) if the Company or any Guarantor is the obligor on such Indebtedness and such Indebtedness is owed to a non-Guarantor Restricted Subsidiary, such Indebtedness must be unsecured and expressly subordinated in right of payment to the prior payment in full in cash of all Obligations with respect to the 2025 Notes, in the case of the Company, or the 2025 Note Guarantee, in the case of a Guarantor; and

(7) the Guarantee by the Company or any Guarantor of Indebtedness of the Company or a Restricted Subsidiary that was permitted to be Incurred by another provision of this covenant;

(12) the Incurrence by the Company or any Restricted Subsidiary of Indebtedness to the extent the net cash proceeds thereof are promptly deposited to defease or to satisfy and discharge the 2025 Notes as described below under “—Legal Defeasance and Covenant Defeasance” or “—Satisfaction and Discharge”;

(13) customer deposits and advance payments received from customers for goods and services sold in the ordinary course of business;

applicable U.S. dollar denominated restriction to be exceeded if calculated at the relevant currency exchange rate in effect on the date of such refinancing, such U.S. dollar-denominated restriction shall be deemed not to have been exceeded so long as the principal amount of such refinancing Indebtedness does not exceed the principal amount of such Indebtedness being refinanced.

The accretion of original issue discount shall be deemed not to be an Incurrence of Indebtedness.

The Company will not Incur any Indebtedness that is contractually subordinate in right of payment to any other Indebtedness of the Company unless it is contractually subordinate in right of payment to the 2025 Notes at least to the same extent. The Company will not permit the co-issuer or any Guarantor to Incur any Indebtedness that is contractually subordinate in right of payment to any other Indebtedness of the co-issuer or such Guarantor, as the case may be, unless it is contractually subordinate in right of payment to the 2025 Notes or such Guarantor’s 2025 Note Guarantee, as the case may be, at least to the same extent. For purposes of the 2025 Indenture, no Indebtedness will be deemed to be contractually subordinated in right of payment to any other Indebtedness of the Issuers or any Guarantor, as applicable, solely by reason of any Liens or Guarantees arising or created in respect thereof.

The Company will not, and will not permit any Restricted Subsidiary to, create, incur, assume or otherwise cause or suffer to exist or become effective any Lien of any kind (other than Permitted Liens) upon any of their property or assets, now owned or hereafter acquired unless all payments due under the 2025 Indenture and the 2025 Notes are secured on an equal and ratable basis with the obligations so secured until such time as such obligations are no longer secured by a Lien.

Limitation on Dividend and Other Payment Restrictions Affecting Restricted Subsidiaries

(4) transfer any of its properties or assets to the Company or any Restricted Subsidiary.

However, the preceding restrictions will not apply to encumbrances or restrictions:

(2) set forth in the 2025 Indenture, the 2025 Notes and the 2025 Note Guarantees;

(5) that restrict in a customary manner the subletting, assignment or transfer of any property or asset that is a lease, license, conveyance or contract or similar property or asset;

The Issuers. The Issuers will not, directly or indirectly: (1) consolidate or merge with or into another Person (whether or not such Issuer is the surviving corporation), or (2) sell, assign, transfer, convey or otherwise dispose of all or substantially all of the properties and assets of the Issuers and the Restricted Subsidiaries taken as a whole, in one or more related transactions, to another Person, unless:

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

(b) the Person formed by or surviving any such consolidation or merger (if other than such Issuer) or to which such sale, assignment, transfer, conveyance or other disposition will have been made (i) is a Person organized or existing under the laws of the United States, any state thereof or the District of Columbia; provided that in the case where such Person is not a corporation, a co-obligor of the 2025 Notes is a corporation organized or existing under such laws and (ii) assumes all the obligations of such Issuer under the 2025 Notes and the 2025 Indenture pursuant to a supplemental indenture reasonably satisfactory to the Trustee;

(4) each Guarantor, unless such Guarantor is the Person with which such Issuer has entered into a transaction under this covenant, will have confirmed to the Trustee in writing that its 2025 Note Guarantee will apply to the obligations of such Issuer or the surviving Person in accordance with the 2025 Notes and the 2025 Indenture; and

(5) the Company delivers to the Trustee an Officers’ Certificate (attaching the arithmetic computation to demonstrate compliance with clause (3) above) and Opinion of Counsel, in each case stating that such transaction and such agreement comply with this covenant and that all conditions precedent provided for in the 2025 Indenture relating to such transaction have been complied with;

Upon any consolidation, merger, sale, assignment, transfer, conveyance or other disposition in accordance with this covenant, the successor Person formed by such consolidation or into or with which such Issuer is merged or to which such sale, assignment, transfer, conveyance or other disposition is made will succeed to, and be substituted for (so that from and after the date of such consolidation, merger, sale, assignment, conveyance or other disposition, the provisions of the 2025 Indenture referring to the “Issuers” will refer instead to the successor Person and not to such Issuer), and may exercise every right and power of, such Issuer under the 2025 Indenture with the same effect as if such successor Person had been named as an Issuer in the 2025 Indenture. In the event of any such transfer, the predecessor will be released and discharged from all liabilities and obligations in respect of the 2025 Notes and the 2025 Indenture and the predecessor may be dissolved, wound up or liquidated at any time thereafter.

The Guarantors. A Guarantor will not, directly or indirectly: (1) consolidate or merge with or into another Person (whether or not such Guarantor is the surviving Person), or (2) sell, assign, transfer, convey or otherwise dispose of all or substantially all of the properties and assets of the Guarantor, in one or more related transactions, to another Person, other than the Company or another Guarantor, unless:

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

(a) the Guarantor is the surviving corporation, or the Person formed by or surviving any such consolidation or merger (if other than the Guarantor) or to which such sale, assignment, transfer, conveyance or other disposition which has been made (i) is organized or existing under the laws of the United States, any state thereof or the District of Columbia and (ii) assumes all the obligations of that Guarantor under the 2025 Indenture, including its 2025 Note Guarantee, pursuant to a supplemental indenture satisfactory to the Trustee; or

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

(2) Restricted Payments that are permitted by the provisions of the 2025 Indenture described above under “—Certain Covenants—Limitation on Restricted Payments” and Permitted Investments;

(3) any issuance or sale of Equity Interests (other than Disqualified Stock) of the Company;

(4) transactions pursuant to agreements or arrangements in effect on the Issue Date and described in the May Offering Memorandum, or any amendment, modification, or supplement thereto or renewal or replacement thereof, as long as such agreement or arrangement, as so amended, modified, supplemented, renewed or replaced, taken as a whole, is not materially more disadvantageous to the Company and the Restricted Subsidiaries than the agreement or arrangement in existence on the Issue Date as determined by the Disinterested Members of the Board of Directors of the Company evidenced by a Board Resolution;

(6) payment of reasonable and customary fees to, and reasonable and customary indemnification arrangements and similar payments on behalf of, directors of the Company or any Subsidiary thereof; and

(2) the gross cash proceeds of that Sale and Leaseback Transaction are at least equal to the Fair Market Value of the property that is the subject of that Sale and Leaseback Transaction; and

The Board of Directors of the Company may designate any Restricted Subsidiary to be an Unrestricted Subsidiary; provided that:

(3) such Subsidiary does not hold any Capital Stock or Indebtedness of, or own or hold any Lien on any property or assets of, or have any Investment in, the Company or any Restricted Subsidiary;

(5) no Default or Event of Default would be in existence following such designation.

Any designation of a Restricted Subsidiary as an Unrestricted Subsidiary will be evidenced to the Trustee by filing with the Trustee the Board Resolution giving effect to such designation and an Officers’ Certificate and an Opinion of Counsel certifying that such designation complied with the preceding conditions and was permitted by the 2025 Indenture. If, at any time, any Unrestricted Subsidiary (x) would fail to meet any of the preceding requirements described in clause (4) above, it will thereafter cease to be an Unrestricted Subsidiary for purposes of the 2025 Indenture, and any Indebtedness, Investments, or Liens on the property, of such Subsidiary will be deemed to be Incurred or made by a Restricted Subsidiary as of such date, and if such Indebtedness, Investments or Liens are not permitted to be Incurred or made as of such date under the 2025 Indenture, the Issuers will be in default under the 2025 Indenture.

The Board of Directors of the Company may at any time designate any Unrestricted Subsidiary to be a Restricted Subsidiary; provided that:

(4) no Default or Event of Default would be in existence following such designation.

The Company will not permit any Restricted Subsidiary, directly or indirectly, to Guarantee any Indebtedness of the Issuers or any Guarantor unless such Restricted Subsidiary (a) is a Guarantor or (b) within ten days executes and delivers to the Trustee an Opinion of Counsel and a supplemental indenture providing for the Guarantee of the payment of the 2025 Notes by such Restricted Subsidiary, which Guarantee will rank senior in right of payment to or equally in right of payment with such Subsidiary’s Guarantee of such other Indebtedness.

The Company will not, and will not permit any Restricted Subsidiary to, directly or indirectly, pay or cause to be paid any consideration to or for the benefit of any Holder of 2025 Notes for or as an inducement to any consent, waiver or amendment of any of the terms or provisions of the 2025 Indenture or the 2025 Notes unless such consideration is offered to be paid to all Holders that may legally participate in the transaction, in the structure proposed by the Company, and is paid to all such Holders of the 2025 Notes that consent, waive or agree to amend in the time frame and in the manner set forth in the solicitation documents relating to such consent, waiver or agreement.

(2) all current reports that would be required to be filed with the Commission on Form 8-K if the Issuers were required to file such reports.

In addition, the Issuers and the Guarantors have agreed that, for so long as any 2025 Notes remain outstanding, they will furnish to the Holders and to prospective investors, upon their request, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act.

(2) default in payment when due (whether at maturity, upon acceleration, redemption or otherwise) of the principal of, or premium, if any, on the 2025 Notes;

(4) failure by the Company or any Restricted Subsidiary for 60 days after written notice by the Trustee or Holders representing 25% or more of the aggregate principal amount of 2025 Notes outstanding to comply with any of the other agreements in the 2025 Indenture;

(a) is caused by a failure to make any payment when due at the final maturity of such Indebtedness (a “Payment Default”); or

(b) results in the acceleration of such Indebtedness prior to its express maturity;

(7) except as permitted by the 2025 Indenture, any 2025 Note Guarantee is held in any judicial proceeding to be unenforceable or invalid or ceases for any reason to be in full force and effect or any Guarantor, or any Person acting on behalf of any Guarantor, denies or disaffirms its obligations under its 2025 Note Guarantee; and

In the case of an Event of Default described in clause (8) above, all outstanding 2025 Notes will become due and payable immediately without further action or notice. If any other Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in principal amount of the then-outstanding 2025 Notes may declare all the 2025 Notes to be due and payable immediately by notice in writing to the Company specifying the Event of Default.

Holders of the 2025 Notes may not enforce the 2025 Indenture or the 2025 Notes except as provided in the 2025 Indenture. Subject to certain limitations, Holders of a majority in principal amount of the then-outstanding 2025 Notes may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders of the 2025 Notes notice of any Default or Event of Default (except a Default or Event of Default relating to the payment of principal or interest) if it determines that withholding notice is in their interest.

The Holders of a majority in aggregate principal amount of the 2025 Notes then outstanding by notice to the Trustee may on behalf of the Holders of all of the 2025 Notes waive any existing Default or Event of Default and its consequences under the 2025 Indenture except a continuing Default or Event of Default in the payment of premium, or interest, or the principal of, the 2025 Notes. However, the Trustee may refuse to follow any direction that conflicts with law or the 2025 Indenture, that may involve the Trustee’s personal liability, or that the Trustee determines in good faith may be unduly prejudicial to the rights of Holders of 2025 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 2025 Notes. A Holder may not pursue any remedy with respect to the 2025 Indenture or the 2025 Notes unless:

(1) the Holder gives the Trustee written notice of a continuing Event of Default;

(2) the Holders of at least 25% in aggregate principal amount of outstanding 2025 Notes make a written request to the Trustee to pursue the remedy;

(3) such Holder or Holders offer the Trustee indemnity reasonably satisfactory to the Trustee against any costs, liability or expense;

(4) the Trustee does not comply with the request within 60 days after receipt of the request and the offer of indemnity; and

(5) during such 60-day period, the Holders of a majority in aggregate principal amount of the outstanding 2025 Notes do not give the Trustee a direction that is inconsistent with the request.

However, such limitations do not apply to the right of any Holder of a 2025 Note to receive payment of the principal of, premium, if any, or interest on, such 2025 Note or to bring suit for the enforcement of any such payment, on or after the due date expressed in the 2025 Notes, which right will not be impaired or affected without the consent of the Holder.

The Company is required to deliver to the Trustee annually within 90 days after the end of each fiscal year a statement regarding compliance with the 2025 Indenture. Within five Business Days of becoming aware of any Default or Event of Default, the Company is required to deliver to the Trustee a statement specifying such Default or Event of Default.

No director, officer, employee, incorporator, stockholder, member, manager or partner of any Issuer or any Guarantor, as such, will have any liability for any obligations of the Company or the Guarantors under the 2025 Notes, the 2025 Indenture, or the 2025 Note Guarantees, or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder of 2025 Notes, by accepting a 2025 Note, waives and releases all such liability. The waiver and release are part of the consideration for issuance of the 2025 Notes. The waiver may not be effective to waive liabilities under the federal securities laws.

The Issuers may, at their option and at any time, elect to have all of its obligations discharged with respect to the outstanding 2025 Notes and all obligations of the Guarantors discharged with respect to their 2025 Note Guarantees (“Legal Defeasance”) except for:

(1) the rights of Holders of outstanding 2025 Notes to receive payments in respect of the principal of, or interest or premium, if any, on such 2025 Notes when such payments are due from the trust referred to below;

(2) the Issuers’ obligations with respect to the 2025 Notes concerning issuing temporary 2025 Notes, registration of 2025 Notes, mutilated, destroyed, lost or stolen 2025 Notes and the maintenance of an office or agency for payment and money for security payments held in trust;

(3) the rights, powers, trusts, duties and immunities of the Trustee, and the Issuers’ and the Guarantors’ obligations in connection therewith; and

In addition, the Issuers may, at their option and at any time, elect to have the obligations of the Issuers and the Guarantors released with respect to certain covenants in the 2025 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 2025 Notes. In the event Covenant Defeasance occurs, certain events (not including non-payment, bankruptcy, receivership, rehabilitation and insolvency events) described under “—Events of Default and Remedies” will no longer constitute Events of Default with respect to the 2025 Notes.

(1) the Company must irrevocably deposit with the Trustee, in trust, for the benefit of the Holders of the 2025 Notes, cash in U.S. dollars, non-callable Government Securities, or a combination thereof, in such amounts as will be sufficient, in the opinion of a nationally recognized firm of independent public accountants, to pay the principal of, and interest and premium, if any, on the outstanding 2025 Notes on the Stated Maturity or on the applicable redemption date, as the case may be, and the Issuers must specify whether the 2025 Notes are being defeased to maturity or to a particular redemption date;

(2) in the case of Legal Defeasance, the Issuers will have delivered to the Trustee an Opinion of Counsel reasonably acceptable to the Trustee confirming that (a) the Issuers have received from, or there has been published by, the Internal Revenue Service a ruling or (b) since the Issue Date, there has been a change in the applicable federal income tax law, in either case to the effect that, and based thereon such Opinion of Counsel will confirm that, the Holders of the outstanding 2025 Notes will not recognize income, gain or loss for federal income tax purposes as a result of such Legal Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Legal Defeasance had not occurred;

(3) in the case of Covenant Defeasance, the Issuers will have delivered to the Trustee an Opinion of Counsel reasonably acceptable to the Trustee confirming that the Holders of the outstanding 2025 Notes will not recognize income, gain or loss for federal income tax purposes as a result of such Covenant Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred;

(8) if the 2025 Notes are to be redeemed prior to their Stated Maturity, the Issuers must deliver to the Trustee irrevocable instructions to redeem all of the 2025 Notes on the specified redemption date under arrangements satisfactory to the Trustee for the giving of notice of such redemption by the Trustee in the Issuers’ names and at the Issuers’ expense; and

The 2025 Indenture will be discharged and will cease to be of further effect as to all 2025 Notes issued thereunder, when:

(a) all 2025 Notes that have been authenticated (except lost, stolen or destroyed 2025 Notes that have been replaced or paid and 2025 Notes for whose payment money has theretofore been deposited in trust and thereafter repaid to the Issuers) have been delivered to the Trustee for cancellation; or

(b) all 2025 Notes that have not been delivered to the Trustee for cancellation (x) have become due and payable (by reason of the mailing of a notice of redemption or otherwise), (y) will become due and payable at Stated Maturity within one year or (z) are to be called for redemption within one year under arrangements satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the Issuers’ names and at the Issuer’s expense, and in each such case the Issuers have irrevocably deposited or caused to be deposited with the Trustee as trust funds in trust solely for the benefit of the Holders of the 2025 Notes, cash in U.S. dollars, non-callable Government Securities, or a combination thereof, in such amounts as will be sufficient, in the opinion of a nationally recognized firm of independent public accountants, without consideration of any reinvestment of interest, to pay and discharge the entire indebtedness on the 2025 Notes not delivered to the Trustee for cancellation for principal, premium, if any, and accrued interest to the Stated Maturity or redemption date, as the case may be;

(2) no Default or Event of Default will have occurred and be continuing on the date of such deposit or will occur as a result of such deposit and such deposit will not result in a breach or violation of, or constitute a default under, any other instrument to which any Issuer or any Guarantor is a party or by which the any Issuer or any Guarantor is bound;

(3) any Issuer or any Guarantor has paid or caused to be paid all sums payable by it under the 2025 Indenture; and

(4) the Issuers have delivered irrevocable instructions to the Trustee under the 2025 Indenture to apply the deposited money toward the payment of the 2025 Notes at Stated Maturity or the redemption date, as the case may be.

In addition, the Issuers must deliver an Officers’ Certificate and an Opinion of Counsel to the Trustee stating that all conditions precedent to satisfaction and discharge have been satisfied.

Except as provided in the next two succeeding paragraphs, the 2025 Indenture and the 2025 Notes may be amended or supplemented with the consent of the Holders of at least a majority in principal amount of the 2025 Notes then outstanding (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, 2025 Notes), and any existing default or compliance with any provision of the 2025 Indenture and the 2025 Notes may be waived with the consent of the Holders of a majority in principal amount of the then-outstanding 2025 Notes (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, 2025 Notes).

Without the consent of each Holder affected, an amendment or waiver may not (with respect to any 2025 Notes held by a non-consenting Holder):

(1) reduce the principal amount of 2025 Notes whose Holders must consent to an amendment, supplement or waiver;

(2) change the Stated Maturity of the principal of, or any installment of interest on, any 2025 Note;

(3) reduce the principal amount of, or premium, if any, or interest on, any 2025 Note;

(4) change the optional redemption dates or optional redemption prices of the 2025 Notes from those stated under “—Optional Redemption”;

(5) waive a Default or Event of Default in the payment of principal of, or interest, or premium, if any, on, the 2025 Notes (except, upon a rescission of acceleration of the 2025 Notes by the Holders of at least a majority in aggregate principal amount of the 2025 Notes, a waiver of the payment default that resulted from such acceleration) or in respect of any other covenant or provision that cannot be amended or modified without the consent of all Holders;

(7) make any change in the amendment and waiver provisions of the 2025 Indenture;

(8) release any Guarantor from any of its obligations under its 2025 Note Guarantee or the 2025 Indenture, except in accordance with the terms of the 2025 Indenture;

(9) impair the right to institute suit for the enforcement of any payment on or with respect to the 2025 Notes or the 2025 Note Guarantees;

arisen, or the obligation of the Issuers to make and consummate an Offer to Purchase in the event of a Change of Control in accordance with the covenant described above under “—Repurchase at the Option of Holders—Change of Control” after such Change of Control has occurred, including, in each case, amending, changing or modifying any definition relating thereto;

(11) except as otherwise permitted under the covenants described above under “—Certain Covenants Merger, Consolidation or Sale of Assets” and “—Certain Covenants—Future Subsidiary 2025 Note Guarantees,” consent to the assignment or transfer by any Issuers or any Guarantor of any of their rights or obligations under the 2025 Indenture.

Notwithstanding the preceding, without the consent of any Holder of 2025 Notes, the Issuers, the Guarantors and the Trustee may amend or supplement the 2025 Indenture or the 2025 Notes:

(1) to cure any provision determined by the Board of Directors of the Company in good faith, evidenced by a Board Resolution, to be an ambiguity, defect or inconsistency;

(2) to provide for uncertificated 2025 Notes in addition to or in place of certificated 2025 Notes;

(3) to provide for the assumption of any Issuer’s or any Guarantor’s obligations to Holders of 2025 Notes in accordance with the 2025 Indenture in the case of a merger or consolidation or sale of all or substantially all of such Issuer’s or such Guarantor’s assets;

(4) to make any change that would provide any additional rights or benefits to the Holders of 2025 Notes or that does not materially, in the good faith determination of the Board of Directors of the Company, evidenced by a Board Resolution, adversely affect the legal rights under the 2025 Indenture of any such Holder;

(5) to comply with requirements of the Commission in order to effect or maintain the qualification of the 2025 Indenture under the Trust Indenture Act;

(6) to comply with the provisions described above under “—Certain Covenants—Future Subsidiary 2025 Note Guarantees”;

(7) to evidence and provide for the acceptance of appointment by a successor Trustee;

(8) to provide for the issuance of Additional 2025 Notes in accordance with the 2025 Indenture; or

(9) to conform the 2025 Indenture or the 2025 Notes to any provision of this “Description of the 2025 Notes” to the extent such provision is intended to be a verbatim recitation thereof.

If the Trustee becomes a creditor of any Issuer or any Guarantor, the 2025 Indenture and the Trust Indenture Act limit its right to obtain payment of claims in certain cases, or to realize on certain property received in respect of any such claim as security or otherwise. The Trustee will be permitted to engage in other transactions; provided that if it acquires any conflicting interest, it must eliminate such conflict within 90 days, apply to the Commission for permission to continue, or resign.

The 2025 Indenture provides that in case an Event of Default occurs and is continuing, the Trustee will be required, in the exercise of its power, to use the degree of care of a prudent man in the conduct of his own affairs. Subject to such provisions, the Trustee will be under no obligation to exercise any of its rights or powers under the 2025 Indenture at the request of any Holder of 2025 Notes, unless such Holder will have offered to the Trustee security and indemnity satisfactory to it against any loss, liability or expense.

Except as set forth below, 2025 Notes will be issued in registered, global form in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof. The 2025 Notes will be issued at the closing of this offering only against payment in immediately available funds.

2025 Notes initially will be represented by one or more notes in registered, global form without interest coupons (collectively, the “2025 Global Notes”). The 2025 Global Notes will be deposited upon issuance with the Trustee as custodian for DTC and registered in the name of DTC or its nominee, in each case for credit to an account of a direct or indirect participant in DTC as described below. Beneficial interest in the 2025 Global Notes may be held only through Euroclear Bank, S.A./N.V as operator of the Euroclear System (“Euroclear”) and Clearstream Banking, S.A. (“Clearstream”) (as indirect participants in DTC).

Except as set forth below, the 2025 Global Notes may be transferred, in whole and not in part, only to another nominee of DTC or to a successor of DTC or its nominee. Beneficial interests in the 2025 Global Notes may be exchanged for 2025 Notes in certificated form. See “—Exchange of 2025 Global Notes for Certificated 2025 Notes.”

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

(1) upon deposit of the Global Notes, DTC will credit the accounts of Participants designated by the Initial Purchasers with portions of the principal amount of the Global Notes; and

Investors in the 2025 Global Notes who are Participants in DTC’s system may hold their interests therein directly through DTC. Investors in the 2025 Global Notes who are not Participants may hold their interests therein indirectly through organizations (including Euroclear and Clearstream) which are Participants in such system. Euroclear and Clearstream will hold interests in the Regulation S Global Notes on behalf of their participants through customers’ securities accounts in their respective names on the books of their respective depositories, which are Euroclear Bank, S.A./N.V., as operator of Euroclear, and Citibank, N.A., as operator of Clearstream. All interests in a Global Note, including those held through Euroclear or Clearstream, may be subject to the procedures and requirements of DTC. Those interests held through Euroclear or Clearstream may also be subject to the procedures and requirements of such systems.

Payments in respect of the principal of, and interest and premium, if any, on a Global Note registered in the name of DTC or its nominee will be payable to DTC in its capacity as the registered Holder under the 2025 Indenture. Under the terms of the 2025 Indenture, the Issuers and the Trustee will treat the Persons in whose names the 2025 Notes, including the 2025 Global Notes, are registered as the owners thereof for the purpose of receiving payments and for all other purposes. Consequently, neither the Issuers, the Trustee nor any agent of the Issuers or the Trustee has or will have any responsibility or liability for:

(1) any aspect of DTC’s records or any Participant’s or Indirect Participant’s records relating to or payments made on account of beneficial ownership interest in the Global 2025 Notes or for maintaining, supervising or reviewing any of DTC’s records or any Participant’s or Indirect Participant’s records relating to the beneficial ownership interests in the Global 2025 Notes; or

(2) any other matter relating to the actions and practices of DTC or any of its Participants or Indirect Participants.

DTC has advised the Issuers that its current practice, upon receipt of any payment in respect of securities such as the 2025 Notes (including principal and interest), is to credit the accounts of the relevant Participants with the payment on the payment date unless DTC has reason to believe it will not receive payment on such payment date. Each relevant Participant is credited with an amount proportionate to its beneficial ownership of an interest in the principal amount of the relevant security as shown on the records of DTC. Payments by the Participants and the Indirect Participants to the beneficial owners of 2025 Notes will be governed by standing instructions and customary practices and will be the responsibility of the Participants or the Indirect Participants and will not be the responsibility of DTC, the Trustee or the Issuers. Neither the Issuers nor the Trustee will be liable for any delay by DTC or any of its Participants in identifying the beneficial owners of the 2025 Notes, and the Issuers and the Trustee may conclusively rely on and will be protected in relying on instructions from DTC or its nominee for all purposes.

DTC has advised the Issuers that it will take any action permitted to be taken by a Holder of 2025 Notes only at the direction of one or more Participants to whose account DTC has credited the interests in the Global 2025 Notes and only in respect of such portion of the aggregate principal amount of the 2025 Notes as to which such Participant or Participants has or have given such direction. However, if there is an Event of Default under the 2025 Notes, DTC reserves the right to exchange the 2025 Global Notes for legended notes in certificated form, and to distribute such notes to its Participants.

Although DTC, Euroclear and Clearstream have agreed to the foregoing procedures to facilitate transfers of interests in the 2025 Global Notes among participants in DTC, Euroclear and Clearstream, they are under no obligation to perform or to continue to perform such procedures, and may discontinue such procedures at any time. Neither the Issuers nor the Trustee nor any of their respective agents will have any responsibility for the performance by DTC, Euroclear or Clearstream or their respective participants or indirect participants of their respective obligations under the rules and procedures governing their operations.

A 2025 Global Note is exchangeable for definitive notes in registered certificated form (“Certificated 2025 Notes”) if:

(1) DTC (a) notifies the Issuers that it is unwilling or unable to continue as depositary for the 2025 Global Notes or (b) has ceased to be a clearing agency registered under the Exchange Act, and in each case the Issuers fail to appoint a successor depositary;

(2) the Issuers, at their option, notify the Trustee in writing that they elect to cause the issuance of Certificated 2025 Notes (DTC has advised the Issuers that, in such event, under its current practices, DTC would notify its participants of the Issuers’ request, but will only withdraw beneficial interests from a Global Note at the request of each DTC participant); or

(3) there will have occurred and be continuing a Default or Event of Default with respect to the 2025 Notes.

In addition, beneficial interests in a Global Note may be exchanged for Certificated 2025 Notes upon prior written notice given to the Trustee by or on behalf of DTC in accordance with the 2025 Indenture. In all cases, Certificated 2025 Notes delivered in exchange for any 2025 Global Note or beneficial interests in 2025 Global Notes will be registered in the names, and issued in any approved denominations, requested by or on behalf of the depositary (in accordance with its customary procedures).

Certificated Notes may not be exchanged for beneficial interests in any Global Note.

The Issuers will make payments in respect of the 2025 Notes represented by the 2025 Global Notes (including principal, premium, if any, interest) by wire transfer of immediately available funds to the accounts specified by the Global Note Holder. The Issuers will make all payments of principal, interest and premium, if any, with respect to Certificated 2025 Notes by wire transfer of immediately available funds to the accounts specified by the Holders thereof or, if no such account is specified, by mailing a check to each such Holder’s registered address. The 2025 Notes represented by the 2025 Global Notes are expected to trade in DTC’s Same-Day Funds Settlement System, and any permitted secondary market trading activity in such 2025 Notes will, therefore, be required by DTC to be settled in immediately available funds. The Issuers expect that secondary trading in any Certificated 2025 Notes will also be settled in immediately available funds.

Set forth below are certain defined terms used in the 2025 Indenture. Reference is made to the 2025 Indenture for a full description of all such terms, as well as any other capitalized terms used herein for which no definition is provided.

“Applicable Premium” means, with respect to a 2025 Note at any date of redemption, the greater of (i) 1.0% of the principal amount of such 2025 Note and (ii) the excess of (A) the present value at such date of redemption of (1) the redemption price of such 2025 Note at May 15, 2020 (as described above under “—Optional Redemption”), plus (2) all remaining required interest payments due on such Note through May 15, 2020 (excluding accrued but unpaid interest to the date of redemption), discounted to present value using a discount rate equal to the Treasury Rate plus 50 basis points, over (B) the principal amount of such 2025 Note.

(1) the sale, lease, conveyance or other disposition (each, a “Transfer”) of any assets; and

(7) a Transfer of accounts receivable in connection with the compromise, settlement or collection thereof in the ordinary course of business or in bankruptcy or similar proceedings;

(8) a Transfer that constitutes a Restricted Payment that is permitted by the covenant described above under “—Certain Covenants—Limitation on Restricted Payments” or a Permitted Investment;
