We have included certain financial measures in this prospectus that are not defined under generally accepted accounting principles in the United States, or GAAP, including Adjusted EBITDA, which is defined as earnings before interest, taxes, depreciation, and amortization (“EBITDA”), adjusted to exclude transaction costs, stock-based compensation, and certain non-cash items. Adjusted EBITDA is not a measurement of our financial performance under GAAP and should not be considered in isolation or as alternatives to net income or any other performance measures derived in accordance with GAAP or as alternatives to cash flows from operating activities as measures of our liquidity.

We use Adjusted EBITDA to evaluate our operating performance and liquidity, and this financial measure is among the primary measures used by management for planning and forecasting future periods. We believe 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 makes it easier to compare our results with the results of other companies that have different financing and capital structures.

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. Our computation of Adjusted EBITDA in this prospectus may also differ in some respects from the calculation of Consolidated Cash Flow in the indentures governing the Notes and the relevant defined term contained in the agreement governing our New Credit Facilities (the “New Credit Agreement”).

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 used capital and intangible assets in our business, and because the payment of income taxes is necessary if we generate taxable income, any measure that excludes these items has material limitations. As a result of these limitations, Adjusted EBITDA 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).

Our industry uses many terms and acronyms that may not be familiar to you. To assist you in reading this prospectus, we have provided definitions of some of these terms below.

4G: Fourth generation of cellular wireless standards. It is a successor to 3G and 2G standards, with the aim to provide a wide range of data services, with rates up to gigabit-speed Internet access for mobile as well as stationary users.

Backbone: A major fiber-optic network that interconnects smaller networks including regional and metropolitan networks. It is the through-portion of a transmission network, as opposed to spurs which branch off the through-portions.

Bandwidth Infrastructure: Lit and dark bandwidth provided over fiber networks. These services are commonly used to transport telecom services, such as wireless, data, voice, Internet, and video traffic between locations. These locations frequently include cellular towers, network-neutral and network-specific data centers, carrier hotels, mobile switching centers, CATV head ends and satellite uplink sites, ILEC central offices, and other key buildings that house telecommunications and computer equipment. Bandwidth Infrastructure services that are lit (i.e., provided by using optronics that “light” the fiber) include private line, Ethernet, and Wavelength services. Bandwidth Infrastructure services that are not lit are sold as dark fiber capacity.

Capacity: The information carrying ability of a telecommunications service. Below is a list of some common units of capacity for bandwidth and colocation services:

Carrier: A provider of communications services that commonly include voice, data, and Internet services.

Carrier Hotel: A building containing many carriers, IXCs, and other telecommunications service providers that are widely interconnected. These facilities generally have high-capacity power service, backup batteries and generators, fuel storage, riser cable systems, large cooling capability, and advanced fire suppression systems.

CDN: Content distribution network; a system of computers networked together across the Internet that cooperate to deliver various types of content to end users. The delivery process is designed generally for either performance or cost.

Central Office: A facility used to house telecommunications equipment (e.g., switching equipment), usually operated by the ILECs and CLECs.

CLEC: Competitive local exchange carrier; provides local telecommunications services in competition with the ILEC.

Cloud Computing: An Internet-based or intranet-based computing environment wherein computing resources are distributed across the network (i.e., the “cloud”), dynamically allocated on an individual or pooled basis, and increased or reduced as circumstances warrant.

Colocation: The housing of transport equipment, other communications equipment, servers, and storage devices within the same location. Some colocation providers are network-neutral, meaning that they allow the customers who colocate in their facilities to purchase Bandwidth Infrastructure and other telecommunications services from third parties. Operators of these colocation facilities sell interconnection services to their customers, enabling them to cross connect with other customers located within the same facility and/or with

Bandwidth Infrastructure providers. Other colocation facilities are operated by service providers and are network-specific in that they require their customers to purchase Bandwidth Infrastructure and other telecommunications services from them.

Conduit: A pipe, usually made of metal, ceramic, or plastic, that protects buried fiber-optic cables.

Data Center: A facility used to house computer systems, backup storage devices, routers, services, and other Internet and other telecommunications equipment. Data Centers generally have environmental controls (air conditioning, fire suppression, etc.), redundant/backup power supplies, redundant data communications connections, and high security.

Dark Fiber: Fiber that has not yet been connected to telecommunications transmission equipment or optronics and, therefore, has not yet been activated or “lit.”

DS: Digital signal level; a measure of the transmission rate of optical telecommunications traffic. For example: DS-1 corresponds to 1.544 Mbps and DS-3 corresponds to 45 Mbps. See the definition of “Capacity,” above.

DWDM: Dense wavelength-division multiplexing. The term “dense” refers to the number of channels being multiplexed. A DWDM system typically has the capability to multiplex greater than 16 wavelengths.

Ethernet: The standard local area network (“LAN”) protocol. Ethernet was originally specified to connect devices on a company or home network as well as to a cable modem or DSL modem for Internet access. Due to its ubiquity in the LAN, Ethernet has become a popular transmission protocol in metropolitan, regional, and long haul networks as well.

Fiber Optics: Fiber, or fiber optic cables, are thin filaments of glass through which light beams are transmitted over long distances.

Gbps: Gigabits per second, a measure of telecommunications transmission speed. One gigabit equals 1 billion bits of information.

ILEC: Incumbent local exchange carrier; a traditional telecommunications provider that, prior to the Telecommunications Act of 1996, had the exclusive right and responsibility for providing local telecommunications services in its local service area.

Interconnection Service: A service that is used to connect two customers who are located within a single building or within a single colocation space using either fiber or other means.

IP: Internet protocol; the transmission protocol used in the transmission of data over the Internet.

ISP: Internet service provider; provides access to the Internet for consumers and businesses.

IXC: Inter-exchange carrier; a telecommunications company that traditionally provided telecom service between local voice exchanges and intrastate or interstate (i.e., long distance) voice exchanges. Today, IXCs frequently provide additional services to their customers beyond voice including data and wireless Internet services.

Lateral/Spur: An extension from the main or core portion of a network to a customer’s premises or other connection point.

Local Loop: A circuit that connects an end customer premise to a metropolitan network, regional network, or backbone network.

LTE Network: Long-term evolution network; can be used to provide 4G cellular networks that are capable of providing high-speed (greater than 100 Mbps) cellular data services.

Mbps: Megabits per second; a measure of telecommunications transmission speed. One megabit equals one million bits of information.

Meet-Me Room: A physical location in a building, usually a data center or carrier hotel, where voice carriers, Internet service providers, data service providers, and others physically interconnect so that traffic can be passed between their respective networks. At any given colocation facility or data center, network owners may also be able to interconnect outside the Meet-Me Room.

Mobile Switching Centers: Buildings where wireless service providers house their Internet routers and voice switching equipment.

MPLS: Multi-protocol label switching; a standards-based technology for speeding up data services provided over a network and making those data services easier to manage.

Multiplexing: An electronic or optical process that combines a large number of lower speed transmissions into one higher speed transmission.

NOC: Network operations center; a location that is used to monitor networks, troubleshoot network degradations and outages, and ensure customer network outages and other network degradations are restored.

OC: Optical carrier level; a measure of the transmission rate of optical telecommunications traffic. For example, OC-3 corresponds to 155 Mbps. See the definition of “Capacity” above.

Optronics: Various types of equipment that are commonly used to light fiber. Optronics includes systems that are capable of providing SONET, Ethernet, Wavelength, and other services over fiber-optic cable.

POP: Point-of-presence; a location in a building separate from colocation facilities and data centers that houses equipment used to provide telecom or Bandwidth Infrastructure services.

Private Line: Dedicated private bandwidth that generally utilizes SONET technology and is used to connect various locations.

Route Miles: The length, measured in non-overlapping miles, of a fiber network. Route miles are distinct from fiber miles, which is the number of route miles in a network multiplied by the number of fiber strands within each cable on the network. For example, if a ten-mile network segment has a 24-count fiber installed, it would represent 10x24 or 240 fiber miles.

SONET: Synchronous optical network; a network protocol traditionally used to support private-line services. This protocol enables transmission of voice, data, and video at high speeds. Protected SONET networks provide for virtually instantaneous restoration of service in the event of a fiber cut or equipment failure.

Streaming: The delivery of media, such as movies and live video feeds, over a network in real time.

Switch: An electronic device that selects the path that voice, data, and Internet traffic take or use on a network.

Tier 1 IP Network: An IP network that participates in the Internet via settlement-free peering.

Transport: A telecommunication service to move data, Internet, voice, video, or wireless traffic from one location to another.

VPN: Virtual private network; a computer network that is implemented as an overlay on top of an existing larger network.

Wavelength: A channel of light that carries telecommunications traffic through the process of wavelength-division multiplexing.

WiMax: Worldwide interoperability for microwave access. WiMax services can be used by 4G cellular networks that are capable of providing high-speed (greater than 100 Mbps) cellular data services.

Overview

We are a provider of bandwidth infrastructure and network-neutral colocation and interconnection services, which are key components of telecommunications and Internet infrastructure services. These services enable our customers to manage, operate, and scale their telecommunications and data networks and data center related operations. We provide our bandwidth infrastructure services over our dense regional, metropolitan, and national fiber networks, enabling our customers to transport data, voice, video, and Internet traffic, as well as to interconnect their networks. Our bandwidth infrastructure services are primarily used by wireless service providers, carriers, other communications service providers, media and content companies, and other bandwidth-intensive enterprises. We typically provide our lit bandwidth infrastructure services for a fixed-rate monthly recurring fee under long-term contracts, which average more than three years in length (and typically average approximately six years for fiber-to-the-tower services). Our dark fiber contracts are generally longer term in nature, averaging approximately twelve years. Our network-neutral colocation and interconnection services facilitate the exchange of voice, video, data, and Internet traffic between multiple third-party networks.

As of March 31, 2012, our fiber networks spanned approximately 45,673 route miles and 2,018,677 fiber miles, served 164 geographic markets in the United States, and connected to 5,431 buildings, including 2,427 cellular towers, allowing us to provide our bandwidth infrastructure services to our customers over redundant fiber facilities between key customer locations. The majority of the markets that we serve and buildings to which we connect have few other networks capable of providing similar bandwidth infrastructure services. We believe this provides us with a sustainable competitive advantage in these markets and buildings. As a result, we believe that the services we provide our customers would be difficult to replicate in a cost- and time-efficient manner. We provide our network-neutral colocation and interconnection services utilizing our own data centers located within three major carrier hotels in the important gateway markets of New York and New Jersey and in facilities located in Chicago, Illinois; Las Vegas, Nevada; Los Angeles, California; Nashville, Tennessee; Plymouth, Minnesota; Cincinnati, Ohio; Cleveland, Ohio; Columbus, Ohio; Pittsburgh, Pennsylvania; and Memphis, Tennessee.

acquired, of $3,036.2 million (after deducting our acquisition cost for OVS and ZEN, two business units that we spun-off to our affiliate Onvoy on March 11, 2010 and April 1, 2011, respectively, and businesses spun-off to those entities in connection with subsequent acquisitions).

Our fiscal year ends June 30 each year and we refer to the fiscal year ended June 30, 2011 as “Fiscal 2011” and the year ending June 30, 2012 as “Fiscal 2012.”

Acquisition of Abovenet

On March 18, 2012, we entered into an Agreement and Plan of Merger with AboveNet, a publicly traded company listed on the New York Stock Exchange. On July 2, 2012, the closing of the transaction contemplated by such agreement occurred (the “AboveNet Acquisition”), pursuant to which we acquired 100% of the outstanding capital stock of AboveNet for a purchase price of approximately $2.2 billion in cash (net of cash acquired). At the closing, each outstanding share of AboveNet common stock was converted into the right to receive $84 in cash.

AboveNet is a provider of bandwidth infrastructure and network-neutral colocation and interconnection services, primarily to large corporate enterprise clients and communication carriers, including Fortune 1000 and FTSE 500 companies in the United States and Europe. AboveNet’s commercial strategy has been consistent with ours: to focus on leveraging its infrastructure assets to provide bandwidth infrastructure services to a select set of customers with high bandwidth demands. It provides lit and dark fiber bandwidth infrastructure services over its dense metropolitan, regional, national, and international fiber networks. It also operates a Tier 1 IP network with direct and indirect (through peering arrangements) connectivity in many of the most important bandwidth centers and peering exchanges in the U.S., Europe, and Japan. Its product set is highly aligned with our own, consisting primarily of dark fiber, wavelength, Ethernet, and IP and colocation services. AboveNet has also grown a very strong base of business with enterprise clients, particularly within the financial services segment.

As of March 31, 2012, AboveNet’s fiber networks spanned approximately 22,789 route miles and 2,587,228 fiber miles and connected to approximately 3,291 on-net buildings, including more than 2,600 enterprise locations, many of which house some of the largest corporate users of network services in the world. AboveNet’s metropolitan networks typically contain 432, and in some cases 864, fiber strands in each cable. This high fiber count allows AboveNet to add new customers in a timely and cost-effective manner by focusing incremental construction and capital expenditures on the laterals that connect to the customer premises. AboveNet’s metropolitan networks serve 17 markets in the U.S., with strong network footprints in a number of the largest metropolitan markets including Boston, Chicago, Los Angeles, New York, Philadelphia, San Francisco, Seattle, and Washington, D.C. It also serves four metropolitan markets in Europe: London, Amsterdam, Frankfurt, and Paris. These locations also include many private data centers and hub locations that are important for AboveNet’s customers. AboveNet uses under-sea capacity on the Japan-U.S. Cable Network to provide connectivity between the U.S and Japan and capacity on the Trans-Atlantic undersea telecommunications network (“TAT-14”) and other trans-Atlantic cables to provide connectivity from the U.S. to Europe.

Recent Developments

Private Notes Offering

In connection with the AboveNet Acquisition, on June 28, 2012, Zayo Escrow Corporation (“Escrow Corp”), a direct wholly-owned subsidiary of the Company, completed a private offering (the “Private Notes Offering”) exempt from registration under the Securities Act of 1933, as amended (the “Securities Act”), of $750,000,000 aggregate principal amount of 8.125% senior secured first-priority notes due 2020 and $500,000,000 aggregate principal amount of 10.125% senior unsecured notes due 2020. On July 2, 2012, the

Company and Zayo Capital, Inc. both assumed the obligations of Escrow Corp under such notes (the “Assumption”). The Issuers assumed the rights and obligations of Escrow Corp under such notes by entering into supplemental indentures to the applicable base indentures governing such notes. Upon consummation of the Assumption, Escrow Corp was merged with and into the Company, with the Company continuing as the surviving entity and as a co-issuer of such notes. $600,000 aggregate principal amount of the 10.125% senior unsecured notes due 2020 was purchased by one of our executive officers and such notes are not included in the exchange offer to which this prospectus relates.

New Credit Facilities and Sponsor Equity Contribution

Concurrent with the closing of the AboveNet Acquisition, we entered into a new $250 million senior secured revolving credit facility (the “New Revolving Credit Facility”) and a new $1.62 billion senior secured term loan facility (the “New Term Loan Facility” and, together with the New Revolving Credit Facility, the “New Credit Facilities”). See “Description of Other Indebtedness.”

In addition, CII, our ultimate parent, concluded the sale of 98,916,060.11 Class C Preferred Units of CII pursuant to certain securities purchase agreements with private investment funds affiliated with GTCR LLC (collectively, “GTCR”), as well as certain existing owners of CII and other investors. The total value of the Class C Preferred Units of CII sold pursuant to the securities purchase agreements was approximately $472 million (the “Sponsor Equity Contribution”), the net proceeds of which were contributed to the Company. As specified in the securities purchase agreements, on July 2, 2012, CII and its members also entered into the Third Amended and Restated Limited Liability Company Agreement and a Second Amended and Restated Registration Rights Agreement, each dated as of July 2, 2012.

A portion of the proceeds from the Sponsor Equity Contribution, together with (i) the net proceeds from the Private Notes Offering and the New Term Loan Facility, and (ii) cash on hand, were used to pay the outstanding portion of our existing credit facilities, to finance our cash tender offer for the $350 million outstanding aggregate principal amount of our Existing Notes (as defined below), to pay the cash consideration for the AboveNet Acquisition, to refinance certain indebtedness of AboveNet in connection therewith, and to pay associated fees and expenses.

Tender for 10.25% Senior Secured Notes and Consent Solicitation

On June 4, 2012, we commenced a cash tender offer and consent solicitation (the “Tender Offer”) for any and all of our $350 million outstanding 10.25% senior secured first-priority notes due 2017 (the “Existing Notes”). On July 2, 2012, we announced that we had accepted for purchase $347 million or 99% of the outstanding Existing Notes that were tendered at the expiration of the Tender Offer. In connection with the Tender Offer, we also received the requisite consents to approve the amendments to the indenture governing the Existing Notes that eliminated most of the restrictive covenants and certain of the events of default and released the collateral securing the obligations under the Existing Notes. Also on July 2, 2012, we announced that we would redeem the remaining $3 million of outstanding Existing Notes on August 1, 2012 pursuant to a Notice of Full Redemption issued on July 2, 2012.

Acquisition of AriaLink

On May 1, 2012, we acquired 100% of the equity interest in Control Room Technologies, LLC, Allegan Fiber Communications, LLC, and Lansing Fiber Communications (collectively, “AriaLink”). The purchase price, which was funded with cash on hand, was $18.0 million and is subject to certain post-closing adjustments.

The AriaLink acquisition added 739 new route miles to our national footprint, including over 300 miles of metropolitan networks in Lansing, Michigan. AriaLink’s network will be interconnected with our existing network, enabling end-to-end bandwidth infrastructure services between our existing approximately 46,000 route mile national network and AriaLink’s network in Michigan.

Entry into Material Definitive Agreement to Acquire FiberGate Holdings, Inc. (“FiberGate”)

On June 4, 2012, we entered into an agreement to acquire 100% of the equity interest in FiberGate (the “FiberGate Acquisition”), a privately held corporation, incorporated in the Commonwealth of Virginia. The purchase price, subject to certain adjustments at closing and post-closing, is $117.0 million and will be paid with cash on hand (including proceeds from the transactions described herein). The agreement is subject to customary closing conditions (including regulatory approval) and includes customary representations, warranties, covenants, and agreements.

Headquartered in Alexandria, Virginia, FiberGate is a provider of dark fiber services throughout the Washington, D.C., Northern Virginia, and Baltimore, Maryland corridor. The FiberGate Acquisition will add 650 unique and dense route miles to our and AboveNet’s already robust metro fiber network in and around the capital region. FiberGate also has 315 on-net buildings, including key government sites, carrier hotels, data centers, cell towers, and enterprise buildings. FiberGate has provided dark fiber services to the federal government since its inception in 1995 and has since expanded its clientele to include large enterprise and carrier customers.

Our Company

Our Business Units

We are organized into three business units: Zayo Bandwidth (“ZB”), zColo, and Zayo Fiber Solutions (“ZFS”). Each business unit is structured to provide sales, delivery, and customer support for its specific telecom and Internet infrastructure services.

Zayo Bandwidth. Through our ZB unit, we provide Bandwidth Infrastructure services over our regional, metropolitan, and national fiber networks. These services are typically lit bandwidth, meaning that we use optronics to “light” the fiber, and consist of private line, wavelength, Ethernet, and IP services. Our target customers within this unit are primarily wireless service providers, carriers, and other communications service providers (including ILECs, IXCs, RLECs, CLECs, and foreign carriers), media and content companies, cable and satellite video providers, and other Internet-centric businesses that require an aggregate minimum of 10 Gbps of bandwidth across their networks.

zColo. Through our zColo unit, we provide network-neutral colocation and interconnection services in three major carrier hotels in the New York metropolitan area and in facilities located in Chicago, Las Vegas, Los Angeles, and Nashville. As a result of the restructuring of our business units, in January 2011, ZEN and ZB transferred five facilities to zColo located in Plymouth, Cincinnati, Cleveland, Columbus, Chicago, and Memphis. In July 2011, ZB transferred an additional colocation facility to zColo, which is located in Pittsburgh. In addition, we are the exclusive operator of the Meet-Me Room at 60 Hudson Street, which is one of the most important carrier hotels in the United States with approximately 300 domestic and international global networks interconnecting within this facility. Our zColo data centers house and power Internet and private-network equipment in secure, environmentally-controlled locations that our customers use to aggregate and distribute data, voice, Internet, and video traffic. Throughout two of the three facilities in the New York City metropolitan area, we operate intra-building interconnect networks that, along with the Meet-Me Room at 60 Hudson Street, are utilized by our customers to efficiently and cost-effectively interconnect with other Internet, data, video, voice, and wireless networks. As of March 31, 2012 and June 30, 2011 the zColo unit managed 94,175 and 72,927 square feet of billable colocation space, respectively.

Zayo Fiber Solutions. The ZFS unit was formally launched on July 1, 2010, after our acquisition of AGL Networks, a company whose business was comprised solely of dark fiber-related services. Through our ZFS unit, we provide dark fiber and related services primarily on our existing fiber footprint. We lease dark fiber pairs to our customers and, as part of our service offering, we manage and maintain the underlying fiber network for the customer. Our customers light the fiber using their own optronics, and as such we do not manage the bandwidth that the customer receives. This allows the customer to manage bandwidth on their own metropolitan and long haul networks according to their specific business needs. ZFS’s customers include carriers and other communication service providers, Internet service providers, wireless service providers, major media and content companies, large enterprises, and other companies that have the expertise to run their own fiber-optic networks. We market and sell dark fiber-related services under long-term contracts (averaging twelve years in length and in some cases more than 20 years); our customers generally pay us on a monthly basis for these services.

Our Business Strategy

Our primary business objective is to be the preferred provider of Bandwidth Infrastructure and network-neutral colocation and interconnection services within our target markets. The following are key elements to our strategy for achieving this objective:

•

Specifically Focus on Bandwidth Infrastructure and Colocation Services. Bandwidth infrastructure and network-neutral colocation and interconnection services are critical network components in the delivery of communications services (including Internet connectivity, wireless voice and data, content delivery, and voice and data networks) by communications service providers to their end users. We believe our disciplined approach and specific focus on providing these critical services to our targeted customers enable us to provide a high level of customer service while at the same time being responsive to changes in the marketplace.

•

Leverage Our Extensive Infrastructure Asset Base by Targeting Customers Within Our Network Footprint. Targeting our sales efforts on markets that are served by our network enables us to reduce our reliance on, and the associated costs of, third-party service providers. This also enables us to provide our customers with a high level of customer service while producing high incremental margins and attractive returns on the capital we invest.

•

Continue to Expand and Leverage Our Fiber-to-the-Tower Footprint. We believe the bandwidth needs for wireless backhaul will continue to grow with the continued adoption of smart phones, tablet PCs, netbooks, and other bandwidth-intensive mobile devices, as well as the escalating deployment of 4G networks. The legacy copper infrastructure that currently serves most cellular towers is not able to provide the same bandwidth capacity as our fiber-based networks. Our existing fiber-to-the-tower networks enable us to sell additional bandwidth to our existing customers as their capacity needs grow, as well as sell our bandwidth infrastructure services to other wireless carriers located on these towers. In addition, we will continue to seek opportunities to expand our fiber-to-the-tower footprint where the terms of the contract provide an attractive return on our investment. The expansion of our fiber-to-the-tower network footprint provides the ancillary benefit of bringing other potential customer locations within reach of our network.

•

Maintain a Disciplined Approach to Capital Investments. A significant portion of our capital expenditures are “success-based,” meaning that the capital is invested only after we have entered into a customer contract with terms that we believe provide an attractive return on our investment. When building our networks, we design them so that adding incremental customers to the network or increasing the bandwidth for an existing customer can be done economically and efficiently. As customer demand increases for our network-neutral colocation and interconnection services, we will seek opportunities to invest in additional data center space.

•

Selectively Expand Through Acquisitions. We have made numerous acquisitions since our founding and we will continue to evaluate potential acquisition opportunities. 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 have consistently demonstrated that we are able to acquire and effectively integrate companies and organically grow revenue and Adjusted EBITDA post-acquisition. Acquisitions have the ability to increase the scale at which we operate, which in turn affords us the ability to increase our operating leverage, extend our network reach, and broaden our customer base. We will continue to evaluate potential acquisitions, both small and large, on a number of criteria, including the quality of the infrastructure assets, the fit within our existing businesses, the opportunity to expand our network, and the opportunity for us to create value as a result of the acquisition. See “Risk Factors—Future acquisitions are a component of our strategic plan, and will include integration and other risks that could harm our business.”

SUMMARY OF THE EXCHANGE OFFER

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 8.125% senior secured first-priority notes due 2020 and 10.125% senior unsecured notes due 2020, but does not include the Accredited Investor Notes (as defined below). The term “Exchange Notes” refers collectively to our 8.125% senior secured first-priority notes due 2020 (the “Secured Exchange Notes”) and 10.125% senior unsecured notes due 2020 (the “Unsecured Exchange Notes) 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, $1,249,400,000 aggregate principal amount of the Outstanding Notes is outstanding, consisting of:

•

$750,000,000 aggregate principal amount of 8.125% senior secured first-priority notes due 2020 (the “Secured Outstanding Notes,” and together with the Secured Exchange Notes, the “Secured Notes”); and

•

$499,400,000 aggregate principal amount of 10.125% senior unsecured notes due 2020 (the “Unsecured Outstanding Notes,” and together with the Unsecured Exchange Notes, the “Unsecured Notes”). This aggregate principal amount does not include $600,000 in aggregate principal amount of 10.125% senior unsecured notes due 2020 purchased by Matthew Erickson, the President of ZFS, in the Private Notes Offering (the “Accredited Investor Notes”). Mr. Erickson qualifies as an “accredited investor” (as defined in Rule 501 under the Securities Act), and his purchase was on terms available to other investors. The Accredited Investor Notes are not eligible to be exchanged in the exchange offer.

We issued the Outstanding Notes in a private transaction 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, 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 , 2012, 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

Upon consummation of the exchange offer, 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. 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 Agreement

We are making the exchange offer pursuant to a registration rights agreement that we entered into on July 2, 2012 with the initial purchasers of the Outstanding Notes (the “registration rights agreement”).

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 the Senior Secured First-Priority Notes” and “Description of the Senior Unsecured Notes” in this prospectus.

Optional Redemption

At any time on or after July 1, 2015, we may redeem the Secured Notes, in whole or in part, at the applicable redemption prices set forth in this prospectus, plus accrued interest.

Before July 1, 2015, we may redeem the Secured Notes, in whole or in part, at a redemption price equal to 100% of their principal amount, plus accrued interest and a “make-whole” premium.

In addition, before July 1, 2015, we may redeem up to 35% of the Secured Notes at a redemption price equal to 108.125% of their principal amount, plus accrued interest, using the proceeds of certain equity offerings.

Subsidiary Guarantees

The Secured Notes will be fully and unconditionally guaranteed, jointly and severally, on a senior secured basis by all of our current and future domestic restricted subsidiaries, which will include each domestic subsidiary of AboveNet. We refer to these subsidiaries as the “Guarantors,” and the guarantees of the Secured Notes as the “Secured Guarantees.”

Collateral and Security

The Secured Notes and the Secured Guarantees will be secured, subject to certain permitted liens, on a first priority basis equally and ratably with the obligations under each of the New Credit Facilities, by a pledge of substantially all assets of the Issuers and the Guarantors that secure the New Credit Facilities (the “Collateral”). For more information, see “Description of the Senior Secured First-Priority Notes—Collateral and Security.”

Subject to certain exceptions, pursuant to an intercreditor agreement, the representative of the series of senior secured obligations that constitute the largest total outstanding amount of any outstanding senior secured obligations has the exclusive right, under the circumstances set forth in the applicable security and collateral agreements, to direct the collateral agent to take actions with respect to the Collateral. The representative of the lenders under the New Credit Facilities will be the controlling representative. See “Description of the Senior Secured First-Priority Notes—Intercreditor Agreement—Enforcement of Security Interests.”

Ranking

The Secured Notes and the Secured Guarantees will be the senior secured obligations of the Issuers and the Guarantors and will:

•

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

•

be secured equally and ratably with each of the New Credit Facilities and any future obligations of the Issuers and the Guarantors that are secured by a first-priority lien on the Collateral;

•

rank senior in right of payment to future indebtedness of the Issuers and the Guarantors that is subordinated in right of payment to the Secured Notes, if any;

•

be structurally subordinated 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 Secured Notes, which will consist only of unrestricted subsidiaries and foreign subsidiaries that do not guarantee any of our other indebtedness; and

•

be effectively senior in right of payment to all of the Issuers’ and the Guarantors’ existing and future unsecured indebtedness to the extent of the value of the Collateral.

As of March 31, 2012, on an as adjusted basis after giving effect to the issuance of the Outstanding Notes and the Assumption, the entry into each of the New Credit Facilities, the Sponsor Equity Contribution, and the use of proceeds from each of the foregoing:

•

the Secured Notes would have been effectively senior in right of payment to the $500 million of Unsecured Notes and $12.0 million in capital lease obligations, in each case to the extent of the value of the Collateral;

•

the Secured Notes would have been effectively equal in right of payment to $1.62 billion of senior secured indebtedness under the New Term Loan Facility; and

•

we would have had an additional $250.0 million available for borrowing under the New Revolving Credit Facility, subject to certain conditions, which amount if borrowed would be effectively equal in right of payment to the Secured Notes.

Terms of the Unsecured Exchange Notes

Securities Offered

$499,400,000 aggregate principal amount of 10.125% senior unsecured notes due 2020. This aggregate principal amount does not include the Accredited Investor Notes, which are not eligible to be exchanged in the exchange offer.

Maturity Date

July 1, 2020

Interest

We will pay interest on the Unsecured Notes semi-annually in arrears on January 1 and July 1 of each year, commencing on January 1, 2013, to holders of record on the December 15 or June 15 immediately preceding the interest payment date.

Before July 1, 2016, we may redeem the Unsecured Notes, in whole or in part, at a redemption price equal to 100% of their principal amount, plus accrued interest and a “make-whole” premium.

In addition, before July 1, 2015, we may redeem up to 35% of the Unsecured Notes at a redemption price equal to 110.125% of their principal amount, plus accrued interest, using the proceeds of certain equity offerings.

See “Description of the Senior Unsecured Notes—Optional Redemption.”

Subsidiary Guarantees

The Unsecured 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, which will include each domestic subsidiary of AboveNet. We refer to the guarantees of the Unsecured Notes as the “Unsecured Guarantees.”

Ranking

The Unsecured Notes and the Unsecured Guarantees will be the senior unsecured obligations of the Issuers and the Guarantors and will:

•

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

•

rank senior in right of payment to future indebtedness of the Issuers and the Guarantors that is subordinated in right of payment to the Unsecured Notes, if any;

•

be effectively subordinated to the Issuers’ and the Guarantors’ secured indebtedness, including the Secured Notes and indebtedness under each of the New Credit Facilities, to the extent of the value of the Collateral securing such indebtedness; and

•

be structurally subordinated 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 Unsecured Notes, which will consist only of unrestricted subsidiaries and foreign subsidiaries that do not guarantee any of our other indebtedness.

As of March 31, 2012, on an as adjusted basis after giving effect to the issuance of the Unsecured Notes and the Assumption, the entry into each of the New Credit Facilities, the Sponsor Equity Contribution, and the use of proceeds from each of the foregoing:

•

the Unsecured Notes would have been effectively subordinated in right of payment to $12.0 million in capital lease obligations to the extent of the value of the collateral securing such capital lease obligations;

•

the Unsecured Notes would have been effectively subordinated in right of payment to $2.25 billion of senior secured indebtedness (consisting of $750.0 million aggregate principal amount of the Secured Notes and $1.62 billion in indebtedness under the New Term Loan Facility) to the extent of the value of the Collateral; and

•

we would have had an additional $250.0 million available for borrowing under the New Revolving Credit Facility, subject to certain conditions, all of which would be effectively senior to the Unsecured Notes if borrowed to the extent of the value of the Collateral.

Terms Common to the Secured Exchange Notes and the Unsecured Exchange Notes

Issuers

Zayo Group, LLC and Zayo Capital, Inc.

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, if any, to the date of repurchase. See “Description of the Senior Secured First-Priority Notes—Repurchase at the Option of Holders—Change of Control” and “Description of the Senior Unsecured Notes—Repurchase at the Option of Holders—Change of Control.”

Certain Covenants

The Indentures will 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 will be subject to a number of important qualifications and exceptions. See “Description of the Senior Secured First-Priority Notes—Certain Covenants” and “Description of the Senior Unsecured 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.

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.

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

We intend to continue to acquire complementary businesses and assets, and some of these acquisitions may be large. 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. Prior to the AboveNet Acquisition, we paid $317.9 million for our largest acquisition to date. We may engage in significantly larger acquisitions similar to the AboveNet Acquisition, which could be much more difficult to integrate. Difficulties with integration could cause material customer disruption and dissatisfaction, which could in turn increase disconnects and reduce new sales.

We may incur additional debt or issue additional preferred units to assist in the funding of these potential transactions, which may increase our leverage and/or dilute our existing equity holders at CII, our ultimate parent. Further, additional transactions (including acquisitions by our parent or affiliates) 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 operations. Acquisitions also involve other operational and financial risks such as:

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

As of March 31, 2012, on an adjusted basis after giving effect to the Private Notes Offering, the entrance into each of the New Credit Facilities, the Sponsor Equity Contribution, and the use of proceeds from each of the foregoing (i) our total debt, including the Notes and capital leases, was $2.7 billion and (ii) we had total borrowing capacity of $250.0 million under the New Revolving Credit Facility. Subject to the limitations set forth in the Indentures and the New 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.

Specifically, our level of debt could have important consequences to the holders of the Notes, including the following:

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 and the value of the Notes. 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 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. Our inability to generate sufficient cash flow to satisfy our debt obligations, including our obligations under the Notes, or to obtain alternative financings, could materially and adversely affect the value of the Notes.

If we are unable to meet our debt service obligations, we would be in default under the terms of the Indentures and the New Credit Agreement. If such a default were to occur, the lenders under the New Credit Facilities could elect to declare all amounts outstanding under each of the New Credit Facilities immediately due and payable, and the lenders under the New Revolving Credit Facility would not be obligated to continue to advance funds thereunder. If the amounts outstanding are accelerated, we cannot assure you that our assets will be sufficient to repay in full the money owed to the lenders or to our debt holders, including holders of the Notes.

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

Since our inception, we have consistently consumed our entire positive cash flow generated from operating activities with our investing activities. To date, our investing activities have consisted principally of the acquisition of businesses as well as material additions of 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, bank debt, the issuance of the Notes, and capital leases.

Our near-term expectation is to continue to invest success-based capital (meaning that the capital is invested only after we have entered into a customer contract with terms that we believe provide an attractive return on our investment) in incremental property and equipment at an amount that may exceed the amount of capital available

from operations after debt service requirements. We also intend to continue to opportunistically pursue acquisitions, some of which may be quite large. In addition to our cash flow from operations, we plan to rely on proceeds from the Notes offering, cash on hand, and availability under the New Credit Facilities. We cannot assure you, however, that we will have access to sufficient cash to successfully operate or grow our business.

We incurred net losses in prior periods and we cannot guarantee that we will generate net income in the future.

We incurred net losses from continuing operations in the last three fiscal years. Our business plan is to continue to expand our network on a success basis, meaning that we attempt primarily to invest capital only when the terms of a customer contract provide an attractive return on our investment. If we continue to expand our network we might continue to incur losses in future periods. In addition, we cannot assure you that we will be successful in implementing our business plan or that we will not change our business plan. Furthermore, if a material number of circuits are disconnected or customers disconnect or terminate their service with us, we may not be able to generate positive net income in future periods. Further, we grant stock-based compensation to employees with terms that require the awards to be classified as liabilities. As such, we account for these awards as a liability and re-measure the liability at each reporting date. To the extent that our valuation increases, additional expense will be recognized at the applicable reporting date. In prior periods, the expense has been a material contributor to our net loss from continuing operations. Additionally, our interest expense will increase with the Private Notes Offering and borrowing under the New Credit Facilities, which will have an adverse effect on our net income.

We are experiencing rapid growth of our business and operations, and we may not be able to 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 intend to continue to rapidly grow our company, including through acquisitions, some of which may be large. Our expansion places strains on our management and our operational and financial infrastructure. Our ability to manage our growth will be particularly dependent upon our ability to:

If we fail to implement these or other necessary measures, our ability to manage our growth and our results of operations will be impaired.

Our back office infrastructure, including the operational support systems, processes, and people is a key component to providing a good experience to our customers, the failure of which could impair our ability to retain existing customers or attract new customers.

Our ability to provide ongoing high-quality service to customers is fundamental to our success. The material failure of one or more of our operational support systems, including the systems for sales tracking, billing, order entry, provisioning, and trouble ticketing, may inhibit us from performing critical aspects of our services for an extended period. If we incur system failures, we may incur additional expenses, delays, and a degradation of customer experience, and we may not be able to efficiently and accurately install new orders for services on a timely basis. Further, the impact of a prolonged failure of these systems could negatively impact our reputation and ability to retain existing customers and to win new business.

Our ability to provide services would be hindered if any of our franchises, licenses, permits, rights-of-way, conduit leases, fiber agreements, or property leases are 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, which could have a material adverse effect on our business, financial condition, and results of operations. In order to operate our networks, we must also maintain fiber leases and IRU agreements that we have with public and private entities. A small percentage of these agreements (less than five percent in route mile terms) expire prior to 2020. 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 might experience the following:

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 and have an adverse effect on our business, financial condition, and results of operations.

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.

If our contracts with our customers are not renewed or are terminated, our business could be substantially harmed.

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. 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 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.

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, and results of operations.

Before giving effect to the AboveNet Acquisition, our largest single customer accounted for approximately 14% and 13% of our monthly recurring revenue during the three and nine months ended March 31, 2012, and total revenues from our top ten customers accounted for approximately 50% of our monthly recurring revenue during both the three and nine months ended March 31, 2012. We currently depend, and expect to continue to depend, upon a relatively small number of customers for a significant percentage of our revenue. If any of our

key customers experience a general decline in demand due to economic or other forces, if the demand for bandwidth does not continue to grow, or if any such customer is not satisfied with our services, such key customer may reduce the number of service orders it has with us, terminate its relationship with us (subject to certain early termination fees), or fail to renew its contractual relationship with us upon expiration.

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 that could adversely affect our operating results and financial condition. As a result of the AboveNet Acquisition, we have a more diverse customer base; however we will still rely on a relatively small number of customers for a significant portion of our revenue.

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 if not met by us, enable customers to claim credits against their payments to us and, under certain conditions, terminate their agreements. Our inability to meet our service level guarantees could adversely affect our revenue and cash flow. 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 or service level agreements with us, could impact our ability to meet our service level agreements and are potentially out of our control.

We are required to maintain, repair, upgrade, and replace our network and our facilities, and our failure to do so could harm our business.

Our business requires that we maintain, repair, upgrade, and periodically replace our facilities and networks. This requires and will continue to require management time and the periodic expenditure of capital. 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, which would adversely affect our business. 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 in order to maintain services to customers. 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 technologies. Our failure to maintain or properly operate this hardware and software can lead to degradations or interruptions in customer service. Our failure to provide proper customer service can result in claims from our customers for credits or damages, can lead to early termination of contracts, and can damage our reputation for service, thereby limiting future sales opportunities.

Any failure of our physical infrastructure or services could lead to significant costs and disruptions that could reduce our revenues, harm our business reputation, and have a material adverse effect on our financial results.

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 at one or more of our data centers, whether or not within our control, could result in service interruptions or equipment damage. 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. We have service level commitment obligations with substantially all of our customers. As a result, service interruptions or equipment damage in our network or at our data centers could result in credits for service interruptions to these customers. We have at times in the past given credits to our customers as a result of service interruptions due to equipment failures. We cannot assume that our customers will accept these credits as compensation in the future. Also, service interruptions and equipment failures may expose us to additional legal liability. We depend on our landlords and other third-party providers to properly maintain the buildings in which our data centers are located. Improper maintenance by such landlords and third parties increase the risk of service interruptions and equipment damage.

We do not own the buildings in which our data centers are located. Instead, we lease our data center space, and the non-renewal of leases could be a significant risk to our ongoing operations.

We would incur significant costs if we were forced to vacate one of our data centers due to the high costs of equipment relation and installation of necessary infrastructure in a new data center. In addition, if we were forced to vacate a data center, we could lose customers that chose our services based on our location. Our landlords could attempt to evict us for reasons beyond our control. Further, we may be unable to maintain good working relationships with our landlords, which would adversely affect our customer service and could result in the loss of customers.

We may be unable to expand our existing data centers or locate and secure suitable sites for additional data centers.

Our data centers may reach high rates of utilization in our key locations. Our ability to meet the growing needs of our existing customers and to attract new customers in these key markets depends on our ability to add additional capacity by incrementally expanding our existing data centers or by locating and securing additional data centers in these markets. Such additional data centers must meet specific infrastructure requirements, such as access to multiple telecommunications carriers, a significant supply of electrical power, and the ability to sustain heavy floor loading. In many markets, the supply of space with these characteristics is limited and subject to high demand.

We may not be able to obtain or construct additional laterals to connect new buildings to our network.

In order to connect a new building to our network, we need to obtain or construct a lateral from our existing network to the building. We may not be able to obtain fiber in an existing lateral at an attractive price or may not be able to construct our own lateral due to the cost of construction or municipal regulatory restrictions. Failure to obtain fiber in an existing lateral or to construct a new lateral could keep us from adding new buildings to our network.

Our services have a long sales cycle, which may have a material adverse effect on our business, financial condition, and results of operations.

A customer’s decision to purchase bandwidth infrastructure services typically involves a significant commitment of our time and resources. As a result, we experience a long sales cycle for some of our services. Furthermore, we may expend significant time and resources in pursuing a particular sale or customer that does not generate revenue. Delays due to the length of our sales cycle or costs incurred that do not result in sales may have a material adverse effect on our business, financial condition, and results of operations.

We were formed in 2007 and have primarily built our operations through the consolidation of 20 acquisitions and asset purchases, the first of which closed in July 2007 and the most recent of which, the AboveNet Acquisition, closed on July 2, 2012.

Prior to our first acquisition, our activities were exclusively related to start-up and corporate development. Our history as a consolidated entity is brief and has been subject to ongoing and substantial change since our inception, consequently there is a limited amount of information upon which you can make an investment decision. Other issuers could have longer histories, which may have greater predictive value.

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 Daniel Caruso, Kenneth desGarennes, Glenn S. Russo, David Howson, Chris Morley, or Matthew Erickson is bound by an employment agreement with us. A portion of Daniel Caruso’s professional time is spent on his service as Executive Chairman of Envysion, Inc., of which he is a significant investor. The loss of members of our management team or other key employees is likely to have a material adverse effect on our business. In addition, our management team’s equity interests are at CII, our ultimate parent. Accordingly, if CII’s other subsidiaries acquire assets, our management could have, indirectly, a significant portion of their equity in another enterprise to which they could devote substantial attention.

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 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 could result in a material adverse effect on our sales, financial condition, and results of operations. 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 have identified a material weakness in our internal controls over financial reporting, and our business may be adversely affected if we do not adequately address that weakness or if we have other material weaknesses or significant deficiencies in our internal control over financial reporting.

We did not adequately implement certain controls to evaluate the amount to be recognized related to deferred income taxes associated with business combinations and we have therefore identified a material weakness in our internal controls over financial reporting as of June 30, 2011. The control deficiency resulted in an error in the purchase accounting associated with our acquisition of FiberNet (See Note 2 to our audited consolidated financial statements contained elsewhere in this prospectus) and a restatement of our annual financial statement for the fiscal years ended June 30, 2011 and 2010, our interim financial statements for each period in fiscal 2011 and the interim financial statements for the first two quarters of the fiscal year ended June 30, 2012. The existence of this or one or more other material weaknesses or significant deficiencies could result in errors in our financial statements, and substantial costs and resources may be required to rectify any internal control deficiencies. If we cannot produce reliable financial reports, investors could lose confidence in our reported financial information, we may be unable to obtain additional financing to operate and expand our business, and our business and financial condition could be harmed.

The telecommunications industry is highly competitive, and contains competitors that have significantly greater resources and a more diversified base of existing customers than we do.

In the telecommunications industry, we compete against ILECs, which have historically provided local telephone services and currently occupy significant market positions in their local telecommunications markets. In addition to these carriers, several other competitors, such as facilities-based communications service providers, including CLECs, cable television companies, electric utilities and large end-users with private networks, offer services similar to those offered by us. Many of our 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. Additionally, some of our brands are relatively new and as such have limited tenure in the market. Many of these competitors have the added advantage of a larger, more diversified customer base. If we fail to develop and maintain brand recognition through sales and marketing efforts and a reputation for high-quality service, we may be unable to attract new customers and risk losing existing customers to competitors with better known brands.

Consolidation among companies in the telecommunications industry could adversely impact our business

The telecommunications industry is intensely competitive and has undergone significant consolidation over the past few years. There are many reasons for consolidation in the industry, including the desire for telecommunication 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 decrease the demand for leased fiber infrastructure assets.

If we do not adapt to swift changes in the telecommunications industry, we could lose customers or market share.

The telecommunications industry is characterized by rapidly changing technology, evolving industry standards, frequent new service introductions, shifting distribution channels, and changing customer demands. We may not be able to adequately adapt our services or acquire new services that can compete successfully. Our failure to obtain and integrate new technologies and applications could impact the breadth of our service portfolio, resulting in service gaps, a less differentiated service suite, and a less compelling offering to customers. We risk losing customers to our competitors if we are unable to adapt to this rapidly evolving marketplace.

In addition, the introduction of new services or technologies, as well as the further development of existing services and technologies, may reduce the cost or increase the supply of certain services similar to those that we provide. As a result, our most significant competitors in the future may be new entrants to the telecommunications industry. These new entrants may not be burdened by an installed base of outdated equipment or obsolete technology. Our future success depends, in part, on our ability to anticipate and adapt in a timely manner to technological changes. Failure to do so could have a material adverse effect on our business.

We are subject to significant regulation that could change or otherwise impact us in an adverse manner.

Telecommunications services are subject to significant regulation at the federal, state, and local levels. These regulations affect our business and our existing and potential competitors. In addition, 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, and 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 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. The FCC regularly considers changes to its 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.

Unfavorable general economic conditions in the United States could negatively impact our operating results and financial condition.

Unfavorable general 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.

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 data center 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.

Changes in regulations affecting commercial power providers may increase our costs.

In the normal course of business, we need to enter into agreements with many providers of commercial power for our office, network, and data centers. Costs of obtaining commercial power can comprise a significant component of our operating expenses. Changes in regulations that affect commercial power providers, particularly regulations related to the control of greenhouse gas emissions or other climate change related matters, could adversely affect the costs of commercial power, which may increase the costs of providing our services. Volatility in market prices for fuel and electricity that affect commercial power providers may also increase the costs of providing our services. Both such increases in our costs may adversely affect our operating results and financial condition.

Rights of holders of the Secured Notes in the Collateral may be adversely affected by bankruptcy proceedings.

The right of the collateral agent for the Secured Notes to repossess and dispose of the Collateral securing the Secured Notes upon the occurrence of an event of default is likely to be significantly impaired by federal bankruptcy law if bankruptcy proceedings are commenced by or against us or our subsidiaries. Upon the commencement of a case for relief under Title 11 of the U.S. Bankruptcy Code (the “Bankruptcy Code”), a secured creditor, such as the collateral agent for the Secured Notes, is prohibited from repossessing its security from a debtor in a bankruptcy case, or from disposing of security repossessed from a debtor, without bankruptcy court approval. Moreover, the Bankruptcy Code permits the debtor to continue to retain and to use the Collateral, and the proceeds, products, rents, or profits of the Collateral, even though the debtor is in default under the applicable debt instruments, provided that the secured creditor is given “adequate protection.” The meaning of the term “adequate protection” may vary according to circumstances, but it is intended in general to protect the value of the secured creditor’s interest in the Collateral from any diminution in the value of the Collateral as a result of the stay of repossession or disposition or any use of the Collateral by the debtor during the pendency of the bankruptcy case. In view of the broad discretionary powers of a bankruptcy court, it is impossible to predict how long payments under the Secured Notes could be delayed following commencement of a bankruptcy case, whether or to what extent the collateral agent would repossess or dispose of the Collateral, or whether or to what extent holders of the Secured Notes would be compensated for any delay in payment or loss of value of the Collateral through the requirements of “adequate protection.” Furthermore, in the event the bankruptcy court determines that the value of the Collateral is not sufficient to repay all amounts due on the Secured Notes, the holders of the Secured Notes would be “undersecured” and have unsecured claims as to the deficiency. Federal bankruptcy laws do not permit the payment or accrual of interest, costs, or attorneys’ fees for “undersecured claims” during the debtor’s bankruptcy case.

In addition to the limitations described above, the collateral agent’s ability to foreclose on the Collateral on behalf of the holders of the Secured Notes may also be challenged on the basis of the argument that the collateral agent’s security interest has not been perfected, required consents of third parties have not been obtained, contractual restrictions, priority issues, state law requirements, FCC and State PUC prior approval obligations, and practical problems associated with the realization of the collateral agent’s security interest in the Collateral securing the Secured Notes, including cure rights, foreclosing on the Collateral within the time periods permitted by third parties or prescribed by laws, statutory rights of redemption and the effect of the order of foreclosure. Given the foregoing, we cannot assure you that in a bankruptcy proceeding the collateral agent will be able to foreclose on the Collateral on behalf of the holders of the Secured Notes or that foreclosure on the Collateral will be sufficient to repay the Secured Notes in full.

The value of the Collateral securing the Secured Notes may not be sufficient to repay the Secured Notes in full.

The Secured Notes and the Secured Guarantees are secured by first-priority liens on the Collateral described in this prospectus (subject to permitted liens and other limitations), equally and ratably with all of our and the Guarantors’ outstanding obligations under the New Credit Facilities and future first lien obligations if any, permitted to be incurred pursuant to the Indentures and the New Credit Agreement. No independent appraisals of any of the Collateral were prepared by or on behalf of us in connection with the Private Notes Offering. The book value of the Collateral should not be relied on as a measure of realizable value for such assets. The value of the Collateral could be impaired in the future as a result of changing economic and market conditions, our failure to successfully implement our business strategy, competition and other factors. A significant portion of the Collateral may include assets that may only be usable as part of the existing operating business. In addition, as of March 31, 2012, 22% of our assets consisted of goodwill and intangible assets. By their nature, our intangible assets may not have a readily ascertainable market value or be readily saleable or, if saleable, there may be substantial delays in their liquidation.

In the event of a foreclosure, liquidation, bankruptcy, or similar proceeding with respect to the Collateral securing the Secured Notes and the Secured Guarantees, the value realized on the Collateral will depend upon many factors, including market and economic conditions, the time period available for a sale, the availability of buyers and the condition of the Collateral. In particular, borrowers often fail to adequately maintain collateral in the period before a bankruptcy. This could significantly reduce the value of the Collateral and your recovery. The indenture governing the Secured Notes does not require that we maintain the current level of the Collateral or maintain a specific ratio of indebtedness to asset values. We cannot assure you that the proceeds from the sale of the Collateral would be sufficient to repay secured noteholders all amounts owed under the Secured Notes and the New Credit Facilities and future first lien obligations. Any proceeds received by the collateral agent in respect of the Collateral for distribution to holders of first lien obligations will be shared by all such parties on a pro rata basis. After taking into consideration such applications of proceeds in respect of the Collateral, the proceeds, if any, available for distribution to holders of the Secured Notes may not be sufficient to fully repay such holders all amounts owed under the Secured Notes.

To the extent that the proceeds of the Collateral are not sufficient to repay amounts owed under the Secured Notes, then holders of the Secured Notes would have general unsecured claims against the remaining assets of the Issuers and the Guarantors, and in the context of a bankruptcy case by or against us, secured noteholders may not be entitled to receive interest payments or reasonable fees, costs or charges due under the Secured Notes, and may be required to repay any such amounts already received by them. Any claim for the difference between the amount, if any, realized by holders of the Secured Notes from the sale of Collateral securing the Notes and the obligations under the Notes will rank equally in right of payment with all of our and the Guarantors’ other senior unsecured indebtedness of the Issuers and the Guarantors and other obligations, including the Unsecured Notes and trade payables.

The value of the Collateral securing the Secured Notes may not be sufficient to secure post-petition interest, costs, and/or attorneys’ fees during bankruptcy.

In the event a bankruptcy is commenced by or against us, holders of the Secured Notes will only be entitled to post-petition interest, costs and/or attorneys’ fees under the bankruptcy code to the extent that the value of their security interest in the Collateral (which would be determined after taking into consideration, among other things, any equal ranking or prior ranking lien claims in the Collateral) is greater than their pre-bankruptcy claim. Holders of indebtedness (including the Secured Notes) that have a security interest in Collateral with a value equal or less than their pre-bankruptcy claim will not be entitled to post-petition interest, costs, or attorneys’ fees under the bankruptcy code. We did not conduct appraisals of any of our assets in connection with the Private Notes Offering and cannot assure you that the value of the secured noteholders’ interest in the Collateral equals or exceeds the principal amount of the Secured Notes at this time, nor can we provide any assurances as to the value of our assets at the time of a subsequent bankruptcy, if any. In addition, the risk that the value of the security interest in the Collateral securing the Secured Notes will be less than the pre-bankruptcy claim of the holders of the Secured Notes will be exacerbated if a bankruptcy court treats the Secured Notes, together with any of our other substantial indebtedness, as a single class for determining the availability of post-petition interest, costs, and/or attorneys’ fees.

State law may limit the ability of the collateral agent for the holders of the Secured Notes to foreclose on the real property and improvements included in the Collateral.

The Secured Notes are secured by, among other things, liens on substantially all the property and assets securing each of the New Credit Facilities. The laws of the states in which the real property and improvements are located may limit the ability of the collateral agent to foreclose on the real property Collateral (including improvements thereon). Laws of those states govern the perfection, enforceability, and foreclosure of mortgage liens against real property interests that secure debt obligations such as the Secured Notes. These laws may impose procedural requirements for foreclosure different from and necessitating a longer time period for completion than the requirements for foreclosure of security interests in personal property. Debtors may have the

right to reinstate defaulted debt (even it is has been accelerated) before the foreclosure date by paying the past due amounts and a right of redemption after foreclosure. Governing laws may also impose “security first” and “one-action” rules, which can affect the ability to foreclose or the timing of foreclosure on real and personal property Collateral regardless of the location of the Collateral and may limit the right to recover a deficiency following a foreclosure.

The holders of the Secured Notes and the trustee also may be limited in their ability to enforce a breach of the covenant described in “Description of the Senior Secured First-Priority Notes—Certain Covenants with Respect to the Collateral—Limitation on Liens.” Some decisions of state courts have placed limits on a lender’s ability to accelerate debt secured by real property upon breach of covenants prohibiting the creation of certain junior liens or leasehold estates, and thus lenders may need to demonstrate that enforcement is reasonably necessary to protect against impairment of the lender’s security or to protect against an increased risk of default. Although the foregoing court decisions may have been preempted, at least in part, by certain federal laws, the scope of such preemption, if any, is uncertain. Accordingly, a court could prevent the trustee and the holders of the Secured Notes from declaring a default and accelerating the Secured Notes by reason of a breach of this covenant, which could have a material adverse effect on the ability of holders to enforce the covenant.

The Collateral can be released in certain circumstances without consent of the holders of the Secured Notes, which would increase the risks in bankruptcy or in other situations.

Under the terms of the indenture governing the Secured Notes, the collateral agreements and the intercreditor agreement, we are permitted to sell or transfer property and other assets included in the Collateral to the extent that such sales or dispositions are permitted under the terms of the indenture governing the Secured Notes. Additionally, if a guarantor of the Secured Notes is released from its respective Secured Guarantee, then the assets of that guarantor will be released from the Collateral. Therefore, the Collateral available to secure the Secured Notes could be reduced in connection with the sale or transfer of assets, subject to the requirements of the indenture governing the Secured Notes.

The indenture governing the Secured Notes permits us, subject to certain limitations and financial tests, to designate one or more of our restricted subsidiaries that is a guarantor of the Secured Notes as an unrestricted subsidiary. If we designate a subsidiary guarantor as an unrestricted subsidiary, all of the liens on any Collateral owned by such subsidiary or any of its subsidiaries and any guarantees of the Secured Notes by such subsidiary or any of its subsidiaries will be released under the indenture governing the Secured Notes. Designation of an unrestricted subsidiary will reduce the aggregate value of the Collateral securing the Secured Notes to the extent that liens on the assets of the unrestricted subsidiary and its subsidiaries are released. In addition, the creditors of the unrestricted subsidiary and its subsidiaries will have a senior claim on the assets of such unrestricted subsidiary and its subsidiaries and holders of the Secured Notes will not. See “Description of the Senior Secured First-Priority Notes—Intercreditor Agreement—Release of Liens on Collateral.”

We will, absent the occurrence and continuance of an event of default under the Indentures, have control over the Collateral, and the sale of particular assets by us could reduce the pool of assets securing the Secured Notes and the Secured Guarantees.

Absent the occurrence and continuance of an event of default under the Indentures or the New Credit Agreement, the collateral documents relating to the Collateral allow us to remain in possession of and retain exclusive control over the Collateral, to operate the Collateral, to alter and repair the Collateral and to collect, invest and dispose of any income from the Collateral securing the Secured Notes and the Secured Guarantees (subject to certain limitations under the Indentures).

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

The Collateral securing the Secured Notes and the Secured Guarantees excludes certain assets, generally as a result of applicable laws and regulations, or the terms of existing agreements, but in some cases due to the high relative cost of granting a perfected security interest in those assets. Property not included in the Collateral includes:

As of the date of this prospectus, we do not have any real property interest that meets the $5.0 million threshold, and as a result there are no mortgages or other grants of security interests in real property at this time.

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

Applicable law requires that a security interest in certain tangible and intangible assets can only be properly perfected and its priority retained through certain actions undertaken by the secured party. The liens on the Collateral securing the Secured Notes may not be perfected with respect to the claims of the Secured Notes if the collateral agent is not able to or does not take the actions necessary to perfect any of such liens. In addition, applicable law requires that certain property and rights acquired after the grant of a general security interest or lien can only be perfected at the time such property and rights are acquired and identified. There can be no assurance that the collateral agent will monitor, or that we will inform the collateral agent of, the future acquisition of property and rights that constitute Collateral, and that the necessary action will be taken to properly perfect the security interest in such after-acquired Collateral. The collateral agent has no obligation to monitor the acquisition of additional property or rights that constitute Collateral or the perfection of any security interest therein. Such failure may result in the loss of the security interest in the Collateral or the priority of the security interest in favor of the Secured Notes against third parties. Additionally, the indenture and the collateral documents entered into in connection with the Secured Notes do not require us to take a number of actions that

might improve the perfection or priority of the liens of the collateral agent in the Collateral. With limited exceptions, the actions we are required to take are limited to (i) the filing of UCC-1 financing statements in the jurisdictions of incorporation of us and the Guarantors, (ii) the granting of mortgages over owned real properties to the extent described under “Description of the Senior Secured First-Priority Notes—Collateral and Security,” (iii) the delivery of stock certificates of domestic subsidiaries, (iv) the entry into control agreements over certain deposit accounts and securities accounts and (v) the delivery of debt instruments in favor of the Guarantors. To the extent that the security interests created by the collateral documents with respect to any Collateral are not perfected, the collateral agent’s rights will be equal to the rights of general unsecured creditors in the event of a bankruptcy.

Any future pledge of Collateral in favor of the trustee or collateral agent, including pursuant to collateral documents delivered after the date of the indenture governing the Secured Notes, may be avoidable by the pledgor (a debtor in possession) or by its trustee in bankruptcy if certain events or circumstances exist or occur, including, among others, if (1) the pledgor is insolvent at the time of the pledge, (2) the pledge permits the holders of the Secured Notes to receive a greater recovery than if the pledge had not been given and the pledgor had commenced a Chapter 7 liquidation and (3) a bankruptcy proceeding in respect of the pledgor is commenced within 90 days following the pledge (or, in certain circumstances, a longer period).

We are obligated to maintain insurance pursuant to the terms of the indenture governing the Secured Notes. However, there are certain losses that may be either uninsurable or not economically insurable, in whole or in part, or against which we may not obtain adequate insurance. As a result, it is possible that insurance proceeds will not compensate us fully for our losses. If there is a total or partial loss of any of the Collateral, we cannot assure you that any insurance proceeds received by us will be sufficient to satisfy all of our secured obligations, including the Secured Notes.

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) do not and will not guarantee the Notes, and the Collateral securing the Secured Notes and the Secured Guarantees excludes all of their respective assets. See “Description of the Senior Secured First-Priority Notes—Secured Note Guarantees” and “Description of the Unsecured Notes—Unsecured 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 New Revolving Credit Facility by 2017, and will need to repay or refinance the indebtedness under the New Term Loan Facility by 2019.

Our New Revolving Credit Facility will mature in 2017, and our New Term Loan Facility will mature in 2019, each of which maturities will occur prior to the maturity of the Notes. If we are unable to repay, extend, or refinance either of the New 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 New 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 Indentures do 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 Indentures governing the Notes, we are 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 Senior Secured First-Priority Notes—Repurchase at the Option of Holders—Change of Control” and “Description of the Senior Unsecured Notes—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 Indentures 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 Indentures. The occurrence of a change of control would also constitute an event of default under our New 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 New 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 Indentures 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.

Each 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 is not insolvent, does not have unreasonably small capital for the business in which we or it is engaged and has not 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.

Borrowings under each of the New Credit Facilities bear, and 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.

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 New 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 conduct our business, and we may be unable to engage in favorable business activities or finance future operations or capital needs. Our ability to comply with some of the covenants and restrictions contained in the agreement governing the New Credit Facilities 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 New Credit Agreement, the Indentures, or any future indebtedness could result in an event of default under our New Credit Facilities, the Indentures 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, our New Credit Facilities require us to comply with specified financial ratios, including ratios regarding total leverage, secured leverage and interest coverage. 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 New 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 our ability to borrow under our New Revolving Credit Facility. If the amounts outstanding under our New 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, the lenders could foreclose on the assets and capital stock pledged to them. See “Description of Other Indebtedness,” “Description of the Senior Secured First-Priority Notes” and “Description of the Senior Unsecured Notes.”

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 is dependent on receipt of dividends from its direct and indirect subsidiaries. Subject to the restrictions contained in the Indentures and the New Credit Agreement, 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 are 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 our New Credit Agreement, the Indentures and the agreements governing our other debt will 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. Our New Credit Agreement and the Indentures 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.

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

We received credit ratings from certain rating services in connection with the Private Notes Offering. 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.

Although we expect that our acquisition of AboveNet will result in benefits to us, we may not realize those benefits because of integration difficulties and other challenges.

The success of our acquisition of AboveNet will depend in large part on the success of management in integrating the operations, strategies, technologies, and personnel of the two companies. We may fail to realize some or all of the anticipated benefits of the AboveNet Acquisition if the integration process takes longer than expected or is more costly than expected. Our failure to meet the challenges involved in successfully integrating the operations of AboveNet or to otherwise realize any of the anticipated benefits of the AboveNet Acquisition, including additional revenue opportunities, could impair our operations. In addition, we anticipate that the overall integration of AboveNet will be a time-consuming and expensive process that, without prior planning and effective and timely implementation, could significantly disrupt our business.

Potential difficulties the combined company may encounter in the integration process include the following:

The anticipated benefits and synergies include the combination of offices in various locations and the elimination of numerous technology systems, duplicative personnel and duplicative market and other data sources. However, these anticipated benefits and synergies assume a successful integration and are based on projections, which are inherently uncertain, and other assumptions. Even if integration is successful, anticipated benefits and synergies may not be achieved or may be of lesser benefit than expected.

We have incurred and will continue to incur transaction, integration, and restructuring costs in connection with the AboveNet Acquisition.

We have incurred and will continue to incur significant costs in connection with the AboveNet Acquisition, including fees of our attorneys, accountants, and financial advisors. We expect to incur additional costs associated with transaction fees and other costs related to the acquisition. We will incur integration and restructuring costs as we integrate the businesses of AboveNet with those of the Company. Although we expect that the realization of efficiencies related to the integration of the businesses will offset incremental transaction, integration, and restructuring costs over time, we cannot give any assurance that this net benefit will be achieved in the near term.

The unaudited pro forma financial data for the Company included in this prospectus is preliminary, and Zayo Group, LLC’s actual financial position and operations after the AboveNet Acquisition may differ materially from the unaudited pro forma financial data included in this prospectus.

The unaudited pro forma financial data for Zayo Group, LLC included in this prospectus is presented for illustrative purposes only and is not necessarily indicative of what Zayo Group, LLC’s actual financial position or operations would have been had the AboveNet Acquisition been completed on the dates indicated. Zayo Group, LLC’s actual results and financial position after the AboveNet Acquisition may differ materially and adversely from the unaudited pro forma financial data included in this prospectus. See “Unaudited Pro Forma Condensed Financial Information.”

The international operations of the combined companies 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:

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

Peering agreements with other ISP’s have allowed AboveNet to access the Internet and exchange traffic with these providers. In most cases, AboveNet peered with these ISP’s on a payment-free basis, referred to as settlement-free peering. We plan to leverage this settlement-free peering on a combined company basis. 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.

Demand for our services from certain customers in the financial services industry may be negatively affected by regulatory changes.

Certain of AboveNet’s financial services customers utilize AboveNet’s network and services for high-frequency trading. To the extent that regulatory changes restrict this activity, the need of these customers for our services may be reduced or eliminated, which could have an adverse effect on our revenues and results of operations.

The following tables present selected unaudited pro forma condensed financial information and operating data of Zayo Group, LLC (co-issuer of the Notes) for the periods and as of the dates indicated. The following unaudited pro forma condensed financial information has been prepared giving effect to (i) the AboveNet Acquisition, (ii) the acquisition of 360networks, (iii) the FiberGate Acquisition, (iv) the Private Notes Offering, (v) the proceeds of the Sponsor Equity Contribution, (vi) the entry into each of the New Credit Facilities, and (vii) the use of proceeds from each of the foregoing. The unaudited pro forma condensed financial information does not give effect to the acquisitions of Arialink or MarquisNet due to insignificance.

The unaudited pro forma condensed financial information as of and for the year ended June 30, 2011 is derived from (i) our audited historical consolidated financial statements for Fiscal 2011, (ii) unaudited historical financial statements of AboveNet for the year ended June 30, 2011, (iii) unaudited historical financial statements of 360networks for the year ended June 30, 2011, and (iv) unaudited historical financial statements of FiberGate for the year ended June 30, 2011.

The unaudited pro forma condensed financial information as of and for the nine months ended March 31, 2012 is derived from (i) our unaudited historical condensed consolidated financial statements for the nine months ended March 31, 2012, (ii) unaudited historical financial statements of AboveNet for the nine months ended March 31, 2012, (iii) unaudited historical financial statements of 360networks for the five months ended November 30, 2011, and (iv) unaudited historical financial statements of FiberGate for the nine months ended March 31, 2012.

As part of the 360networks acquisition, we acquired VoIP360, Inc., a legal subsidiary of 360networks. The VoIP360, Inc. entity held substantially all of 360networks Voice over Internet Protocol (“VoIP”) and other voice product offerings. Effective April 1, 2011, we spun-off our voice operations to Zayo Group Holdings Inc. (“Holdings”), our parent company, in order to maintain our focus on our Bandwidth Infrastructure business. To further this objective, concurrently with the close of the 360networks acquisition, we spun-off 360networks VoIP operations comprising VoIP 360, Inc. and certain other 360networks operations to Holdings. The adjustment included in the pro forma statements of operations during the year ended June 30, 2011 and the nine months ended March 31, 2012 include an adjustment to remove the VoIP business from the historical results of 360networks.

The unaudited pro forma condensed financial information reflect pro forma adjustments that are described above and in the accompanying notes and are based on available information and certain assumptions that we believe are reasonable under the circumstances. The pro-forma balance sheets and statements of operations below reflect our preliminary estimates of the acquisition date fair values of the assets and liabilities assumed in the AboveNet Acquisition and to be assumed in the FiberGate acquisition. The determination of the fair values of the acquired assets and assumed liabilities (and the related determination of estimated lives of depreciable tangible and identifiable intangible assets) requires significant judgment. The Company has not completed its valuation analysis and calculations in sufficient detail necessary to arrive at the final estimates of the fair value of the acquired assets and liabilities assumed, along with the related allocations to goodwill and intangible assets. The unaudited pro forma condensed financial information is presented for informational purposes only and does not purport to be indicative of what would have occurred had the events actually been consummated at the beginning of the periods presented, nor is it necessarily indicative of our future consolidated operating results.

The selected unaudited pro forma condensed financial information should be read in conjunction with the accompanying notes thereto, the information contained in “Selected Historical Consolidated Financial Information” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” and our audited consolidated financial statements as of and for the year ended June 30, 2011, the audited consolidated financial statements as of and for the year ended December 31, 2011 of AboveNet, the audited consolidated financial statements as of and for the year ended December 31, 2010 of 360networks, and the audited consolidated financial statements as of and for the year ended December 31, 2011 of FiberGate, each included elsewhere in this prospectus.

Notes to the Unaudited Condensed Statements of Operations for the nine months ended March 31, 2012 and year ended June 30, 2011.

Additionally, AboveNet incurred approximately of $0.1 million and $0.2 million of operating costs with FiberGate during the nine months ended March 31, 2012 and year ended June 30, 2011, respectively. These expenses have been removed in the “AboveNet Pro Forma Adjustments” column.

The Company would have recognized $70.2 million in expenses associated with debt extinguishment costs during the year ended June 30, 2011, including an expense of $18.1 million associated with writing-off the Company’s unamortized debt acquisition costs, an expense of $42.6 million associated with the payment of early redemption fees on the Company’s previous indebtedness, and an expense of $9.4 million associated with writing off the net unamortized discount on the extinguished debt balances. These non-recurring expenses have not been reflected in the pro-forma results of operations, above.

Note: The purchase price allocations from the AboveNet Acquisition and pending acquisition of FiberGate, discussed above, are preliminary pending the Company’s completion of its acquisition accounting procedures associated with valuing the net assets acquired which will include independent valuation of identified tangible and intangible assets acquired.

The following tables present selected historical consolidated financial information for Zayo Group, LLC for the periods and as of the dates indicated. The selected historical consolidated financial information for Zayo Group, LLC as of and for the years ended June 30, 2011, 2010, 2009 and 2008 is derived from, and qualified by reference to, our audited consolidated financial statements included elsewhere in this prospectus. The selected historical consolidated financial information for Zayo Group, LLC as of March 31, 2012 and for the nine months ended March 31, 2012 and 2011 is derived from, and qualified by reference to, our unaudited consolidated financial statements included elsewhere in this prospectus. Our unaudited consolidated financial statements have been prepared on the same basis as our audited consolidated financial statements and, in our opinion, reflect all adjustments, consisting only of normal and recurring adjustments, necessary for a fair presentation of such financial statements in all material respects.

We were organized in May 2007, and our first substantive activity was the acquisition of Memphis Networks LLC on July 31, 2007 and of PPL Telecom LLC on August 24, 2007. PPL Telecom LLC is our predecessor company, however, we do not believe that reliable financial statements for PPL Telecom LLC for prior periods can be produced. As such, no selected financial information for periods prior to our fiscal year ended June 30, 2008 have been set forth in this table.

The financial data set forth in the following tables should be read in conjunction with our historical consolidated financial statements and related notes and “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” each included elsewhere in this prospectus. The results for any interim period are not necessarily indicative of the results that may be expected for a full year or any future period.

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

Because a portion of the proceeds from the offering of Secured Outstanding Notes was used to refinance our $350.0 million senior secured note balance outstanding on July 2, 2012 (our “Previous Secured Indebtedness”) and our ratio of earnings to fixed charges would change by ten percent or more as a result of such repayment, we are presenting our pro forma ratio of earnings to fixed charges below. The adjustments to derive the pro forma ratio are limited to the net change in interest resulting from the refinancing. As only a portion of the proceeds from the offering of Secured Outstanding Notes was used to retire our Previous Secured Indebtedness, only the related portion of the interest has been used in calculating the pro forma adjustment.

In computing the pro forma ratio, the historical ratio is adjusted by the pro forma interest expense adjustment which is calculated as follows:

The pro forma ratio of earnings to fixed charges calculated below does not give pro forma effect to our recent acquisitions.

This exchange offer is being made pursuant to the registration rights agreement. The summary of the registration rights agreement contained herein does not purport to be complete and is qualified in its entirety by reference to the registration rights agreement. A copy of the registration rights agreement 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 , 2012, 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, delay, non-acceptance, termination, or amendment as promptly as practicable by a public announcement, and in the case of an extension, no later than 9:00 a.m., New York City time, on the next business day after the previously scheduled expiration time.

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 will determine in our sole discretion 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. We reserve the absolute right to:

Our determinations, either before or after the expiration time, under, and of the terms and conditions of, the exchange offer, including the letter of transmittal and the instructions to it, or as to any questions with respect to the tender of any Outstanding Notes, 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 written notice to the exchange agent. 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 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 be subject to the provisions in the Indentures and the legend contained on the Outstanding Notes regarding the transfer restrictions of the Outstanding Notes. 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 and any Outstanding Notes 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.

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

(2) the exchange offer is not consummated on or before June 28, 2013, for any reason; 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 commercially reasonable efforts to cause the shelf registration statement to be declared effective by the SEC reasonably promptly but in any event on or prior to 60 days 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 agreement 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 agreement. It does not restate the registration rights agreement in its entirety. We urge you to read the registration rights agreement, which is an exhibit to the registration statement of which this prospectus forms a part and can also be obtained from us.

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 “Unaudited Pro Forma Condensed Financial Information,” our unaudited interim financial statements and condensed notes as of and for the nine month periods ended March 31, 2012 and 2011 and our audited financial statements and notes as of June 30, 2011 and 2010, and for the fiscal years ended June 30, 2011, 2010 and 2009 included in this prospectus. The results of operations for the periods reflected herein may not necessarily be indicative of results that may be expected for future periods, nor are interim results necessarily indicative of full year results.

We are a provider of bandwidth infrastructure and network-neutral colocation and interconnection services, which are key components of telecommunications and Internet infrastructure services. These services enable our customers to manage, operate, and scale their telecommunications and data networks and data center related operations. We provide our bandwidth infrastructure services over our dense regional, metropolitan, and national fiber networks, enabling our customers to transport data, voice, video, and Internet traffic, as well as to interconnect their networks. Our bandwidth infrastructure services are primarily used by wireless service providers, carriers and other communications service providers, media and content companies, and other bandwidth-intensive enterprises. We typically provide our lit bandwidth infrastructure services for a fixed-rate monthly recurring fee under long-term contracts, which average more than three years in length (and average approximately six years for fiber-to-the-tower services). Our dark fiber contracts are generally longer term in nature, averaging approximately twelve years. Our network-neutral colocation and interconnection services facilitate the exchange of voice, video, data, and Internet traffic between multiple third-party networks.

As of March 31, 2012, our fiber networks spanned approximately 45,673 route miles and 2,018,677 fiber miles, served 164 geographic markets in the United States, and connected to 5,431 buildings, including 2,427 cellular towers, allowing us to provide our bandwidth infrastructure services to our customers over redundant fiber facilities between key customer locations. The majority of the markets that we serve and buildings to which we connect have few other networks capable of providing similar bandwidth infrastructure services, which we believe provides us with a sustainable competitive advantage in these markets. As a result, we believe that the services we provide to our customers would be difficult to replicate in a cost- and time-efficient manner. We provide our network-neutral colocation and interconnection services utilizing our own data centers located within three major carrier hotels in the important gateway markets of New York and New Jersey and in facilities located in Chicago, Illinois; Las Vegas, Nevada; Los Angeles, California; Nashville, Tennessee; Plymouth, Minnesota; Cincinnati, Ohio; Cleveland, Ohio; Columbus, Ohio; Pittsburgh, Pennsylvania; and Memphis, Tennessee.

We are a wholly-owned subsidiary of Zayo Group Holdings, Inc., a Delaware corporation (“Holdings”), which is in turn 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, 2011 as “Fiscal 2011” and the year ending June 30, 2012 as “Fiscal 2012.”

When assessing the results of our operations, we review such results at our business unit level. As of March 31, 2012, the Company consisted of three business units: Zayo Bandwidth (“ZB”), zColo, and Zayo Fiber Solutions (“ZFS”). Our ZB unit focuses on lit bandwidth infrastructure product offerings. ZFS focuses on dark fiber infrastructure products and the zColo unit focuses on network-neutral colocation and interconnection services. See “Business—Overview—Our Business Units” for further discussion of our business units.

We are an active participant in federal broadband stimulus projects created through the American Recovery and Reinvestment Act. To date, we have been awarded, as a direct recipient, federal stimulus funds for two projects and as a sub-recipient federal stimulus funds for one project by the National Telecommunication and Information Administration. The projects involve the construction, ownership, and operation of fiber networks for the purpose of providing broadband services to governmental and educational institutions, as well as underserved, and usually rural, communities. As part of the award, the federal government funds a large portion of the construction and development costs. On the three projects awarded to us to date, as either a direct or sub-recipient, the stimulus funding will cover, on average, approximately 75% of the total expected cost of the projects. All of these projects allow for our ownership or use of the network for other commercial purposes, including the sale of our bandwidth infrastructure services to new and existing customers. The details of the three awards are as follows:

We were founded in 2007 in order to take advantage of the favorable Internet, data, and wireless growth trends driving the demand for bandwidth infrastructure services. These trends have continued in the years since our founding, despite volatile economic conditions, and we believe that we are well-positioned to continue to capitalize on those trends. We have built our network and services through 20 acquisitions and asset purchases (including the AboveNet Acquisition) for an aggregate purchase consideration, net of cash acquired, of $3,036.2 million (after deducting our acquisition cost for OVS and ZEN, two business units operated by our affiliate Onvoy, which we spun-off on March 11, 2010 and April 1, 2011, respectively).

On December 1, 2011, we acquired 100% of the equity of 360networks. We paid the purchase price of approximately $317.9 million, net of approximately $1.0 million in cash acquired and net of an assumed working

capital deficiency of approximately $26.0 million. Included in the $317.9 million purchase price was VoIP 360, Inc., a legal subsidiary of 360networks. The VoIP360, Inc. entity held substantially all of 360networks Voice over Internet Protocol (“VoIP”) and other voice product offerings. Effective January 1, 2011, we spun-off our voice operations to Holdings in order to maintain focus on our Bandwidth Infrastructure business. Concurrently with the close of the 360networks acquisition, we spun-off 360networks VoIP operations to Holdings. On the spin-off date, we estimated the net fair value of the VoIP assets and liabilities which were contributed to Holdings to be $11.7 million.

The acquired 360networks business operates approximately 19,789 route miles of intercity and metropolitan fiber network across 22 states and British Columbia. 360networks’ intercity network interconnects over 70 markets across the central and western United States, including 23 of our fiber markets and a number of new markets such as Albuquerque, New Mexico; Bismarck, North Dakota; Des Moines, Iowa; San Francisco, California; San Diego, California; and Tucson, Arizona. In addition to its intercity network, 360networks operates over 800 route miles of metropolitan fiber networks across 26 markets, including Seattle, Washington; Denver, Colorado; Colorado Springs, Colorado; Omaha, Nebraska; Sacramento, California; and Salt Lake City, Utah.

The results of the legacy 360networks business are included in the operating results of the ZB and ZFS business units beginning December 1, 2011.

On December 31, 2011, we entered into an Asset Purchase Agreement with MarquisNet. The agreement was consummated on the same date, at which time our zColo business unit acquired substantially all of the net assets of MarquisNet for a purchase price of $15.5 million, subject to post-closing adjustments. The acquisition was funded with a draw on our revolving line-of-credit.

The acquired MarquisNet business operates a single 28,000 square foot data center which provides colocation services in Las Vegas, Nevada. With this acquisition, our zColo business unit operates thirteen interconnect-focused colocation facilities.

The operating results of the acquired business are included in zColo’s operating results beginning on January 1, 2012.

On July 1, 2010, we acquired 100% of the equity of AGL Networks from its parent, AGL Resources Inc., and changed AGL Networks’ name to Zayo Fiber Solutions, LLC. We paid the purchase price of approximately $73.7 million with cash on hand. AGL Networks’ assets were comprised of dense, high-fiber-count networks totaling 786 route miles and over 180,000 fiber miles, and included 281 incremental on-net buildings across the metropolitan markets of Atlanta, Georgia, Charlotte, North Carolina, and Phoenix, Arizona. AGL Networks generated all of its revenue from providing dark fiber related services to both wholesale and enterprise customers.

In connection with the AGL Networks acquisition, we established the ZFS unit on July 1, 2010. The assets of AGL Networks complement our existing dark fiber services, which had previously been provided by ZEN and ZB. Subsequent to the acquisition, we transferred those existing dark fiber customer contracts to our ZFS unit and began leveraging a portion our pre-existing fiber network to provide dark fiber solution offerings.

The results of the legacy AGL Networks business are included in the operating results of the ZFS business unit beginning on July 1, 2010.

On October 1, 2010, we completed a merger with AFS, the parent company of American Fiber Systems, Inc. (“AFS Inc.”). The AFS merger was consummated with the exchange of $110.0 million in cash and a $4.5 million non-interest bearing promissory note due in October 2012 for all of the interest in AFS. We calculated the fair value of the promissory note to be $4.1 million resulting in an aggregate purchase price of $114.1 million. The AFS merger was effected through a merger between AFS and a special purpose vehicle created for the AFS merger. The purchase price was based upon the valuation of both the business and assets directly owned by AFS and the ownership interest in US Carrier Telecom Holdings, LLC, held by AFS Inc. for which we estimated the fair value to be $15.1 million. AFS is a provider of bandwidth infrastructure services in nine metropolitan markets: Atlanta, Georgia; Boise, Idaho; Cleveland, Ohio; Kansas City, Missouri; Las Vegas, Nevada; Minneapolis, Minnesota; Nashville, Tennessee; Reno, Nevada; and Salt Lake City, Utah. AFS owns and operates approximately 1,251 route miles and approximately 172,415 fiber miles of fiber networks and has approximately 600 incremental on-net buildings in these markets.

The results of the legacy AFS business are included in the operating results of the ZB and ZFS business units beginning on October 1, 2010.

On September 20, 2010, our zColo business unit acquired certain colocation assets in Nashville, Tennessee from Dolphini Corporation for a cash purchase price of $0.2 million.

The table below summarizes the net cash paid for all of our acquisitions and asset purchases since our inception.

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

On June 4, 2012, we entered into an Agreement and Plan of Merger to acquire 100 percent of the equity interest in FiberGate. See “Prospectus Summary—Recent Developments—Entry into Material Definitive Agreement to Aquire FiberGate Holdings, Inc. (“FiberGate”)” for a description of FiberGate’s business.

As discussed in “Business—Overview—Our Business Units” below, effective April 1, 2011, we spun-off our ZEN business unit to Holdings. During the three and nine months ended March 31, 2011, the results of the operations of ZEN have been aggregated and are presented in a single caption entitled, “Earnings from discontinued operations, net of income taxes” on our consolidated statements of operations. Prior to the spin-off, transactions with the ZEN business unit were eliminated in consolidation. Subsequent to the spin-off transactions with ZEN are reflected within our results of operations.

All discussions contained in this “Management’s Discussion and Analysis of Financial Condition and Results of Operations” relate only to our results of operations from our continuing operations.

During the nine months ended March 31, 2012 and 2011, we invested $102.8 million (net of stimulus grant reimbursements) and $87.7 million (net of stimulus grant reimbursements), respectively, in capital expenditures related to property and equipment primarily to expand our fiber network and largely in connection with new customer contracts. During Fiscal 2011, 2010 and 2009, we invested $112.5 million (net of stimulus grant reimbursements), $58.8 million (net of stimulus grant reimbursements) and $61.6 million, respectively, in capital expenditures related to property and equipment primarily to expand our fiber network and largely in connection with new customer contracts. We expect to continue to make significant capital expenditures in future periods.

We had total indebtedness (excluding capital leases) of $690.0 million and $354.4 million as of March 31, 2012 and June 30, 2011, respectively. Our indebtedness as of June 30, 2011 principally included our $350.0 million of Senior Secured Notes (“Existing Notes”), the net proceeds from which were used to fund our acquisitions and for other working capital purposes. The nominal interest rate on our Existing Notes is fixed at 10.25%. Our indebtedness as of March 31, 2012 also includes a $315.0 million term loan (the “Existing Term Loan Facility”) which was entered into on December 1, 2011 in order to fund the 360networks acquisition. The interest rate on the Existing Term Loan Facility is floating and was 7.0% as of March 31, 2012. During the three months ended March 31, 2012, we also made a $30.0 million draw on our existing revolving credit facility (the “Existing Revolving Credit Facility”) in order to fund the acquisition of MarquisNet and to pay certain short term liabilities assumed in the 360networks acquisition. The interest rate on the Existing Revolving Credit Facility is floating and was 4.75% as of March 31, 2012.

As a result of the growth of our business from the acquisitions, discussed above, 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.

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. 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 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.

Most revenue is billed in advance on a fixed-rate basis. The remainder of revenue is billed in arrears on a transaction basis determined by customer usage. Fees billed in connection with customer installations and other up-front charges are deferred and recognized as revenue ratably over the contract life.

Revenue attributable to leases of dark fiber pursuant to indefeasible rights-of-use agreements (“IRUs”) are 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. However, ASC 360-20 Property Plant and Equipment: Real Estate Sales, allows for full profit recognition on IRU contracts when the following conditions have been met: 1) the sale has been consummated, 2) the buyer’s initial and continuing investments are adequate to demonstrate a commitment to pay for the property, 3) the sellers receivable is not subject to future subordination, and 4) the seller has transferred to the buyer the usual risks and rewards of ownership in a transaction that is in substance a sale and does not have a substantial continuing involvement with the property. During Fiscal 2011, the Company recognized revenue in the amount of $1.1 million related to a fiber sale. The Company did not enter into any contracts during the years ended June 30, 2010 or 2009 that would have required sales-type accounting treatment.

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 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 lease certain network facilities, primarily infrastructure assets such as lit fiber circuits, dark fiber, and colocation assets, to augment our owned infrastructure for which we are generally billed a fixed monthly fee. We also use the facilities of other carriers for which we are billed on a usage basis.

We recognize the cost of these facilities or services when it is incurred in accordance with contractual requirements. We dispute incorrect billings. The most prevalent types of disputes include disputes for circuits that are not disconnected on a timely basis and usage bills with incorrect or inadequate call detail records. Depending on the type and complexity of the issues involved, it may take several quarters to resolve disputes.

In determining the amount of such operating expenses and related accrued liabilities to reflect in our financial statements, we consider the adequacy of documentation of disconnect notices, compliance with prevailing contractual requirements for submitting such disconnect notices and disputes to the provider of the facilities, and compliance with our interconnection agreements with these carriers. Significant judgment is required in estimating the ultimate outcome of the dispute resolution process, as well as any other amounts that may be incurred to conclude the negotiations or settle any litigation.

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 common units granted to employees are considered to be stock-based compensation with terms that require the awards to be classified as liabilities. As such, we account for these awards as a liability and re-measure the liability at each reporting date until the date of settlement. Each reporting period we adjust the value of the vested portion of our liability awards to their fair value. The preferred units granted to certain employees and directors are considered to be stock-based compensation with terms that require the awards to be classified as equity. As such, we account for these awards as equity, which requires us to determine the fair market value of the award on the grant date and amortize the related expense over the vesting period of the award.

We use a third party valuation firm to assist in the valuation of our common units for each reporting period and preferred units when granted. In developing a value for these units, we utilize a two-step valuation approach. In the first step we estimate the value of our equity instruments through an analysis of valuations associated with various future potential liquidity scenarios for our shareholders. The second step involves allocating this value across our capital structure. The valuation is conducted in consideration of the guidance provided in the American Institute of Certified Public Accountant (“AICPA”) Practice Aid “Valuation of Privately-Held Company Equity Securities Issued as Compensation” and with adherence to the Uniform Standards of Professional Appraisal Practice (“USPAP”) set forth by the Appraisal Foundation.

In estimating our fair value, we have historically evaluated both market- and income-based valuation techniques. The income approach was based on our projected free cash flows. In our market-based approach, the valuation was estimated based on the prices paid by investors and acquirers of interest of comparable companies in the public and private markets. The valuation was based on a weighted average of the market and income valuation techniques. As a result of our expansion since inception and due to the fact that the committed capital from our ultimate investors has been fully funded, the potential of a liquidation event for our shareholders in the future has increased. As such, we have revised the market-based approach utilized in our valuation to account for potential liquidation events.

During Fiscal 2011, we employed a probability-weighted estimated return method to value our common units. The method estimates the value of the units based on an analysis of values of the enterprise assuming various future outcomes. 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. This approach utilizes a variety of assumptions regarding the likelihood of a certain scenario occurring, if the event involves a transaction, the potential timing of such an event, and the potential valuation that each scenario might yield. The potential future outcomes that we considered were remaining a private company with the same ownership, a sale or merger, an initial public offering (“IPO”), and a partial recapitalization.

We most heavily weighted the valuation estimate associated with remaining a private entity with the same ownership. In this assumption, we assessed our value using a discounted cash flow approach, which involves developing a projected free cash flow, estimating an appropriate risk adjusted present value discount rate, calculating the present value of our projected free cash flows, and calculating a terminal value. In estimating our fair value, we utilized the following discounted cash flow valuation techniques: Total Enterprise Value to Terminal Revenue and Total Enterprise to Terminal EBITDA. There are several inputs that are required to develop an estimate of the enterprise value when utilizing these income approaches including, forecasted earnings, discount rate, and the terminal multiple. We have developed a forecast of our revenues and EBITDA through December 31, 2015. Our forecasted revenues and EBITDA are based on our composition as of the balance sheet date, not adjusted for potential acquisitions. The next step in the income approach is to estimate a discount rate which most appropriately reflects our cost of capital which we estimated to be 13%. In determining this discount rate, we utilized a weighted average cost of capital (“WACC”) utilizing the Capital Asset Pricing Model (“CAPM”) build-up method. This method derives the cost of equity in part from the volatility (risk) statistics suggested by the Guideline Public Companies in the form of their five year historical betas. We included certain incremental risk premiums specific to us to account for the fact that we have historically depended on outside investment to operate, are significantly smaller than the Guideline Public Companies and have a history of substantial volatility in earnings and cash flows. Based on our projections and discount rate we estimate the present value of our future cash flows. In order to estimate the enterprise value we add to the estimated discounted cash flows an estimated terminal value. The terminal value is estimated utilizing the “Observed Market Multiple” method. This method requires us to observe prevailing valuations associated with the Guideline Public Companies and the acquisitions of guideline Companies. This terminal value is converted to a present value through the use of an appropriate present value factor.

For purposes of the probability-weighted expected return method valuation, management also considered various liquidation possibilities including an IPO, a sale or merger, and a partial recapitalization. In each of these scenarios a distribution is established around the estimated dates and valuations of each scenario. Future valuation figures are based upon corresponding market data for comparable companies in comparable scenarios. These include publicly traded valuation statistics and acquisition valuation statistics for comparable companies in the IPO scenario and sale/merger scenario, respectively. Valuation statistics are combined with expectations regarding our future economic performance to produce future valuation estimates. Estimates are then translated to present value figures through the use of appropriate discount rates.

We also considered the likelihood of a near-term recapitalization. In this scenario, we would complete a partial recapitalization of our equity, and to facilitate the ultimate liquidity for all investors, we would pursue a future sale via an IPO or a sale to a financial or strategic buyer.

The third scenario that we reviewed in determining our enterprise value was a dual track exit in which we engage in a formal process with an investment banker to achieve liquidity for existing shareholders. In this scenario, we would simultaneously evaluate both an IPO and a sale of the Company. As part of the sale process, we would engage in discussions with both financial and strategic buyers.

Based on these scenarios, management calculated the probability-weighted expected return to all of the equity holders. The resulting enterprise valuation is 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 are satisfied, the remaining proceeds are 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 Class A preferred unit holders and 20% to the common unit holders depending upon the return multiple to the Class A preferred unit holders up to the amount of the Class A gain percentage. Once the amount of proceeds related to the Class A percentage gain has been distributed, then proceeds attributable to the Class B gain percentages are distributed in a similar method as the Class A gains.

The value attributable to each class of shares is 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 which we believe indicates a reasonable spectrum of discounts for each of the valuation techniques utilized. The empirical methods we utilized rely on datasets procured from observed transactions in interests in the public domain that are perceived to incorporate pricing information related to the marketability (or lack thereof) of interest itself. These empirical methods include IPO Studies and Restricted Stock Studies. The primary theoretical models utilized in our analysis were the option pricing approach, discounted cash flow, and Quantitative Marketability Discount Model. Based on a review of these approaches, we estimated the appropriate marketability discount to be in the range of 11.7% and 23.02%.

Determining the fair value of share-based awards at the grant date and subsequent reporting dates requires judgment. If actual results differ significantly from these estimates, stock-based compensation expense and the Company’s results of operations could be materially impacted.

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 is directly related to the construction and installation of network infrastructure assets. 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, which is reduced by any reimbursements received for such costs. 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. During Fiscal 2011 and the nine months ended March 31, 2012, the Company capitalized interest in the amount of $3.7 million and $3.6 million, respectively. No interest was capitalized during Fiscal 2010 or Fiscal 2009.

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: a) tax losses that can be carried forward to be utilized against taxable income in future years; and b) 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 level of deferred tax asset recognition is influenced by management’s assessment of our future profitability with regard to relevant business plan forecasts. 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 profitability.

In connection with several of our acquisitions, we have acquired significant net operating loss carryforwards (“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 occurred.

As of March 31, 2012, we have a cumulative NOL carry forward balance of $197.4 million of which we expect to utilize all but $52.9 million. During the year ended June 30, 2011, we added $41.2 million to our NOL carryforward balance as a result of NOLs acquired from the AFS merger. These NOLs, if not utilized to reduce taxable income in future periods, will expire in various amounts beginning in 2015 and ending in 2029. We utilized NOLs to offset income tax obligations in each of the years ended June 30, 2010 and 2009 and during the nine months ended March 31, 2012. As a result of Internal Revenue Service regulations, we are currently limited to utilizing a maximum of $18.8 million NOLs during Fiscal 2012; however, to the extent that we do not utilize $18.8 million of NOLs during a fiscal year, the difference between the $18.8 million maximum usage and the actual NOLs used is carried over to the next fiscal year. During the year ended June 30, 2011, we generated an NOL of $107.8 million due to the availability of bonus depreciation on new assets placed in service during the fiscal year. This fiscal 2011 loss is not limited by the Section 382 limitation described above. The deferred tax assets recognized at June 30, 2011 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 NOLs are available would result in full utilization of our current unreserved NOLs.

We perform an assessment of goodwill for impairment annually in April of each year or more frequently if we determine that indicators of impairment exist. Our impairment review process compares the fair value of each reporting unit to its carrying value. Our reporting units are consistent with the reportable business units identified in Note 18—Segment Reporting, to our audited consolidated financial statements included elsewhere in this prospectus.

In performing the annual goodwill impairment test, if the fair value of the reporting unit exceeds its carrying value, goodwill is not impaired and no further testing is performed. If the carrying value of the reporting unit exceeds its estimated fair value, then a second step must be performed, and the implied fair value of the reporting unit’s goodwill must be determined and compared to the carrying value of the reporting unit’s goodwill. If the

carrying value of a reporting unit’s goodwill exceeds its implied fair value, then an impairment loss equal to the difference will be recorded.

We consider the use of multiple valuation techniques in accordance with fair value measurements and disclosures guidance to estimate the fair value of its reporting business units and have consistently applied an income and market-based approach to measure fair value.

Under the income approach, we estimate the reportable segment’s fair market value using the discounted cash flow method. The discounted cash flow method involves the following key steps:

In developing the projected free cash flows, we utilize expected growth rates implied by the financial projections that have been developed by management. The cash flow forecasts are based upon upside, midpoint, and downside scenarios. In developing the discount rate, we use a rate that reflects the cost of capital for the Company. This cost of capital reflects the relative risk of an investment in the Company, and the time value of money. We calculate this discount rate using the weighted-average cost of capital formula. Management estimated the weighted-average cost of capital for the ZB business unit to be 12.1% and 13.2% for the ZFS business unit. Using the projected cash flow and discount rate inputs, we calculate the present value of our projected cash flows. In calculating the terminal value, we estimate a long-term growth rate that we believe appropriately reflects the expected long-term growth in nominal U.S. gross domestic product. The terminal value is converted to a present value through the use of the appropriate present value factor. This figure is then summed with the present value of projected free cash flow for the projection period to render a valuation estimate for each reporting segment.

Under the market approach, we estimate the reportable segment’s fair market value using the Analysis of Guideline Public Companies method. The use of this method involves the following:

In identifying and selecting the guideline companies that could be deemed appropriate for our reporting units, we screened potential companies using a research tool with parameters including constraints regarding geographic location, primary industry classification, and market capitalization. We selected the Enterprise Value to Revenue and EBITDA ratios as the most appropriate market based valuation technique for us. With the assistance of a third-party valuation firm, we estimated the 2011 revenue trading multiples based on Guideline Public Companies. Utilizing third-party market studies, we estimated a control premium as part of the market based calculations, which is in-line with historical control premiums offered for comparable transactions in the communications industry, the availability of financing, and number of potential buyers.

In estimating the fair market value of each of our reportable segments, we averaged the valuations from each of the approaches above. The resulting valuations are significantly higher than the current carrying value of

these segments. Although we estimate the fair value of our segments utilizing the average of various valuation techniques, none of the valuation techniques on a stand-alone basis indicated an impairment of any of our segments.

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 most 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 of one year or less 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, as well as the assumptions and estimates used to determine the cash inflows and outflows. 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 and 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 forecasted amounts and the difference could be material.

Our operating costs consist primarily of third-party network service costs, colocation facility costs and colocation facility utilities costs. Third-party network service costs result from our leasing of certain network facilities, primarily leases of circuits and dark fiber, from other local exchange carriers to augment our owned infrastructure for which we are generally billed a fixed monthly fee. Our colocation facility costs comprise rent and license fees paid to the landlords of the buildings in which our zColo business operates along with the utility costs to power those facilities.

Recurring transport costs are the largest component of our operating costs and primarily include monthly service charges from telecommunication carriers related to the circuits and dark fiber utilized by us to interconnect our customers. While increases in demand will drive additional operating costs in our business, we expect to primarily utilize our existing network infrastructure and augment, when necessary, with additional circuits or services from third-party providers. Transport costs include the upfront cost of the initial installation of such circuits.

Our selling, general and administrative (“SG&A”) expenses include personnel costs, costs associated with the operation of our network (network operations), and other related expenses, including sales commissions,

marketing programs, office rent, professional fees, travel, software maintenance costs, costs incurred related to potential and closed acquisitions (i.e., transaction costs) and other expenses.

After compensation and benefits, network operations expenses are the largest component of our SG&A expenses. Network operations expenses include all of the non-personnel related expenses of maintaining our network infrastructure, including contracted maintenance fees, right-of-way costs, rent for locations where fiber is located (including cellular towers), pole attachment fees, and relocation expenses.

We compensate certain members of our management and independent directors through grants of common units of CII, which vest over varying periods of time, depending on the terms of employment of each such member of management or directors. In addition, certain of our senior executives and independent directors have been granted preferred units of CII.

For the common units granted to members of management and directors, we recognize an expense equal to the fair value of all of those common units vested during the period, and record a liability in respect of that amount. Subsequently, we recognize changes in the fair value of those common units through increases or decreases in stock-based compensation expense and related adjustments to the related stock-based compensation liability.

When the preferred units are initially granted, we recognize no expense. 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. Subsequent changes in the fair value of the preferred units granted to those executive officers and directors are not taken into consideration as we amortize that expense.

Nine Months Ended March 31, 2012 Compared to the Nine Months Ended March 31, 2011

Our total revenue during the nine months ended March 31, 2012 increased by $63.1 million, or 30%, from $209.4 million to $272.5 million during the nine months ended March 31, 2011 and 2012, respectively. The increase in revenue was impacted by the October 1, 2010 AFS merger, the December 1, 2011 acquisition of 360networks and December 31, 2011 acquisition of MarquisNet. The monthly recurring revenue on the acquisition date of the acquired AFS, 360networks, and MarquisNet businesses was approximately $2.3 million, $7.0 million and $0.6 million, respectively. The remaining increase in revenue recognized during the nine months ended March 31, 2012 as compared to the nine months ended March 31, 2011 was a result of organic growth. As a result of internal sales efforts since March 31, 2011, we have entered into $572.0 million of gross new sales contracts, which will represent an additional $8.0 million in monthly revenue once installation on those contracts is accepted. Since March 31, 2011, we have received acceptance on gross installations that have resulted in additional monthly revenue of $6.9 million as of March 31, 2012, as compared to March 31, 2011. This increase in revenue related to our organic growth is partially offset by total customer churn of $4.6 million in monthly revenue since March 31, 2011.

The stratification of our revenue during the nine months ended March 31, 2012 and 2011 was consistent with a majority of the revenue recognized during the periods presented resulting from monthly recurring revenue streams. The following table reflects the stratification of our revenues during these periods:

Zayo Bandwidth. Our revenues from our ZB operating segment increased by $37.5 million, or 24%, from $158.2 million to $195.8 million during the nine months ended March 31, 2011 and 2012, respectively. The increase is a result of both acquisition and organic growth. Of the approximately $2.3 million in acquired monthly recurring revenue from AFS, approximately $1.5 million was assigned to the ZB operating segment. Additionally, $5.4 million of the acquired monthly recurring revenue from 360networks was assigned to the ZB operating segment. As a result of internal sales efforts since March 31, 2011, the ZB segment entered into $263.1 million of gross new sales contracts, which will represent an additional $5.2 million in monthly revenue once installation on those contracts is accepted. Since March 31, 2011, ZB received acceptance on gross installations that have resulted in additional monthly revenue of $4.8 million as of March 31, 2012, as compared to March 31, 2011. This increase in revenue related to organic growth is partially offset by total customer churn at ZB of $3.7 million in monthly revenue since March 31, 2011. Also offsetting the increase in revenue is a decrease resulting from ZB transferring certain intra-building and colocation assets and the related customer revenues to the zColo segment on January 1, 2011 and July 1, 2011.

Zayo Fiber Solutions. Our revenues from our ZFS operating segment increased by $17.1 million or 55% from $31.1 million to $48.2 million during the nine months ended March 31, 2011 and 2012, respectively. The increase is a result of both acquisition and organic growth. Of the approximately $2.3 million in acquired monthly recurring revenue from AFS, approximately $0.8 million was assigned to the ZFS operating segment. Additionally, $1.6 million of the acquired monthly recurring revenue from 360networks was assigned to the ZFS operating segment. Since March 31, 2011, ZFS received acceptance on gross installations that have resulted in additional monthly revenue of $1.3 million as of March 31, 2012, as compared to March 31, 2011. This increase in revenue related to organic growth is partially offset by total customer churn at ZFS of $0.2 million in monthly revenue since March 31, 2011.

zColo. Our revenues from our zColo segment increased by $7.1 million, or 29% from $24.4 million to $31.6 million during the nine months ended March 31, 2011 and 2012, respectively. The increase is a result of acquisition and organic growth and as a result of certain intra-building and colocation services which were migrated from ZB to zColo subsequent to March 31, 2011. The Company acquired MarquisNet on December 31, 2011 and the entire MarquisNet business was allocated to the zColo segment. The monthly recurring revenue on the acquisition date of the acquired MarquisNet business was approximately $0.6 million. Since March 31, 2011, zColo received acceptance on gross installations that have resulted in additional monthly revenue of $0.8 million as of March 31, 2012, as compared to March 31, 2011. This increase in revenue related to organic growth is partially offset by total customer churn at zColo of $0.6 million in monthly revenue since March 31, 2011. Effective January 1, 2011, the ZB segment transferred contracts amounting to approximately $0.3 million in monthly recurring revenue to the zColo business unit and effective July 1, 2011, ZB transferred a colocation facility in Pittsburgh, Pennsylvania and the associated quarterly recurring revenue of approximately $0.1 million to the zColo segment.

Our operating costs, excluding depreciation and amortization, increased by $6.5 million, or 12% from $53.3 million to $59.8 million during the nine months ended March 31, 2011 and 2012, respectively. The increase in operating costs, excluding depreciation and amortization, primarily relates to additional network costs incurred in order to support new customer contracts entered into subsequent to March 31, 2011 and additional costs associated with the acquired 360networks and MarquisNet businesses. The 12% increase in operating costs, excluding depreciation and amortization, occurred during the same period in which our revenues increased by 30%. The lower ratio of operating costs as compared to revenues is primarily a result of gross installed revenues having a lower component of associated operating costs than the prior period’s revenue base and churned revenue due to a higher percentage of our newly installed revenue being supported by our owned infrastructure assets (i.e., on-net). The ratio also benefited from synergies realized related to our previous acquisitions.

The table below sets forth the components of our SG&A expenses during the nine months ended March 31, 2012 and 2011.

Compensation and Benefits Expenses. Compensation and benefits expenses increased by $4.1 million, or 14%, from $29.9 million to $34.1 million during the nine months ended March 31, 2011 and 2012, respectively. The increase reflects the increased number of employees hired during the year to support our growing business. At March 31, 2012 we had 485 full time employees compared to 393 at March 31, 2011. A majority of the increase to our headcount occurred on December 1, 2011 as a result of hiring certain former employees of 360networks.

Network Operations Expenses. Network operations expenses increased by $6.3 million, or 31%, from $20.1 million to $26.4 million during the nine months ended March 31, 2011 and 2012, respectively. The increase in such expenses principally reflects the growth of our network assets and the related expenses of operating that expanded network. The ratio of network operating expenses as compared to revenues was consistent during the three months ended March 31, 2012 and 2011 at 10%.

Other SG&A. Other SG&A expenses, which includes expenses such as property tax, franchise fees, travel, office expense, and maintenance expense on colocation facilities, decreased by $1.3 million, or 8%, from $16.5 million to $15.2 million during the nine months ended March 31, 2011 and 2012, respectively. The decrease is principally a result of reduced franchise fees resulting from favorable renegotiations on existing franchise agreements. These savings were partially offset by increases in other SG&A expenses associated with our acquisitions of 360networks and MarquisNet.

Stock-based compensation expense decreased by $9.1 million, or 32%, from $28.8 million to $19.7 million during the nine months ended March 31, 2011 and 2012, respectively. During the quarter ended March 31, 2011,

we began employing a probability-weighted estimated return method to value our common units. The method estimates the value of the units based on an analysis of values of the enterprise assuming various future outcomes. 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. Prior to quarter ended March 31, 2011, the company estimated the fair value of the common units utilizing market-and income-based valuation techniques. Moving to the probability-weighted estimated return method resulted in a significant increase to the estimated value of the common units during the quarter ended March 31, 2011 which in turn resulted in a higher stock-based compensation expense during the three and nine months ended March 31, 2011.

The stock-based compensation expense associated with the common units is impacted by both the estimated value of the common units and the number of common units vesting during the period. During the nine months ended March 31, 2012, an additional 18.0 million units vesting as compared to the three months ended March 31, 2011. The following table reflects the estimated fair value of the common units during the relevant periods impacting the stock compensation expense for the nine months ended March 31, 2012 and 2011.

Depreciation and amortization expense increased by $16.8 million, or 38%, from $43.9 million to $60.7 million during the nine months ended March 31, 2011 and 2012, respectively. The increase is a result of the substantial increase to our property and equipment and intangible asset balance since March 31, 2011, principally from $127.6 million in capital expenditures since March 31, 2011 and the increase to our property and equipment and intangible balance due to the AFS acquisition on October 1, 2010, the 360networks acquisition on December 1, 2011 and MarquisNet acquisition on December 31, 2011.

Interest expense increased by $10.8 million, or 45%, from $24.3 million to $35.1 million during the nine months ended March 31, 2011 and 2012, respectively. The increase is a result of our increased indebtedness during the nine months ended March 31, 2012 as compared to the nine months ended March 31, 2011. In connection with the 360networks acquisition, we entered into a $315.0 million Term Loan agreement on December 1, 2011 which accrued interest during the period at 7.0%. During the quarter ended December 31, 2011, we borrowed an additional $30.0 million against our Existing Revolving Credit Facility which accrued interest at a floating rate ranging from 4.0% to 4.75% during the period. Additionally, on September 14, 2010 we issued an additional $100.0 million in Existing Notes which accrued interest at 10.25%.

Income tax expense increased during the period by $11.3 million from $7.5 million to $18.8 million during the nine months ended March 31, 2011 and 2012, respectively. Our provision for income taxes includes both the current provision and a provision for deferred income tax expense resulting from timing differences between tax and financial reporting accounting bases. We are unable to combine our net operating losses (“NOLs”) for

application to the income of our subsidiaries in some states and thus our state income tax expense is higher than the expected blended rate. In addition, as noted above, we are subject to limits on the amount of carry forward NOLs that we may use each year for federal and state purposes.

The following table reconciles an expected tax provision based on a statutory federal tax rate of 34% applied to our book net income.

The effective tax rate is significantly affected by the amount of non-deductible stock-based compensation recognized during the year. As part of estimating the annual effective tax rate, the company is required to estimate the amount of non-deductible stock-based compensation the Company will incur in future periods. Due to changes is business and market conditions, it is difficult to forecast the value of the common units and the resulting impact on the non-deductible stock-based compensation expense during the year and as such the estimated annual effective tax rate can change in future interim periods.

We define Adjusted EBITDA as earnings from continuing operations before interest, income taxes, depreciation, and amortization adjusted to exclude transaction costs, stock-based compensation, and certain non-cash items. We use Adjusted EBITDA to evaluate operating performance and liquidity, and these financial measures are among the primary measures used by management for planning and forecasting of future periods. We believe Adjusted EBITDA is especially important in a capital-intensive industry such as telecommunications. We further 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 makes it easier to compare our results with the results of other companies that have different financing and capital structures.

We also monitor Adjusted EBITDA as we have debt covenants that restrict our borrowing capacity that are based on a leverage ratio which utilizes a modified EBITDA, as defined in our credit agreement, which is materially consistent with our Adjusted EBITDA definition. We must not exceed a consolidated leverage ratio (funded debt to annualized modified EBITDA), as determined under the credit agreement, of 4.25x the last quarter’s annualized modified EBITDA. 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 substitutes 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. Reconciliations from net earnings/(loss) from continuing operations to Adjusted EBITDA and net cash provided by operating activities to Adjusted EBITDA are as follows:

Reconciliation from net cash provided by continuing operating activities to Adjusted EBITDA

Our revenue was generated from the following business units during the years ended June 30, 2011 and 2010:

Our total revenue increased by $87.9 million, or 44%, from $199.3 million to $287.3 million for the year ended June 30, 2010 and 2011, respectively. The increase is principally a result of the AGL Networks acquisition and the AFS merger, which occurred on the first day of the first and second quarter of Fiscal 2011, respectively. Also contributing to the increase is growth in revenues resulting from the addition of new customer services. As a result of internal sales efforts since June 30, 2010 we have entered into $425.0 million of gross new sales contracts, which will represent an additional $6.7 million in monthly recurring revenue once installation on those contracts is accepted. Since June 30, 2010, we have received acceptance on gross installations that have resulted in additional monthly recurring revenue of $6.0 million as of June 30, 2011, as compared to June 30, 2010. This increase in revenue related to our organic growth is offset by total customer churn of $3.9 million in monthly revenue since June 30, 2010.

The stratification of our revenue during the years ended June 30, 2011 and 2010 was consistent with a majority of the revenue recognized during the periods presented resulting from monthly recurring revenue streams. The following table reflects the stratification of our revenues during these periods:

Zayo Bandwidth. Our revenues from our Zayo Bandwidth business unit increased by $31.1 million, or 17%, from $183.1 million to $214.1 million during the years ended June 30, 2010 and 2011, respectively. This increase is primarily a result of additional revenue associated with the AGL Networks acquisition and AFS merger during Fiscal 2011 and organic growth related to our sales efforts and expansion of our network. Partially offsetting this increase is the impact of Zayo Bandwidth transferring to Zayo Fiber Solutions its dark fiber assets and customer contracts as of July 1, 2010. Additionally, as of January 1, 2011 Zayo Bandwidth transferred certain intra-building and colocation assets and the related customer contracts to the zColo unit. The transfer of these customer contracts from Zayo Bandwidth to zColo resulted in a decrease to revenue of $1.1 million at ZB during the year ended June 30, 2011.

zColo. Our revenues from our zColo business unit increased by $9.9 million or 41% from $24.0 million to $33.9 million during the years ended June 30, 2010 and 2011, respectively. Our colocation revenues are primarily derived from the assets acquired from the acquisition of FiberNet in September of 2009. The year-over-year increase in revenues is primarily a result of a full year of operating results generated by the legacy FiberNet colocation assets during Fiscal 2011. Also contributing to the increase are revenues from intra-building and colocation services which were migrated from the ZB to the zColo unit effective January 1, 2011. The transfer of these customer contracts from Zayo Bandwidth to zColo resulted in an additional $1.1 million in revenue being recognized at the zColo unit during the year ended June 30, 2011.

Zayo Fiber Solutions. The Zayo Fiber Solutions business unit was established on July 1, 2010. The revenue recognized by Zayo Fiber Solutions during the year ended June 30, 2011 includes dark fiber contracts acquired in our AGL Networks acquisition and our merger with AFS. The revenue in Fiscal 2011 also includes revenue from dark fiber revenue from customers that were transferred from the Zayo Bandwidth and Zayo Enterprise Networks business units upon the formation of the Zayo Fiber Solutions business unit on July 1, 2010. We have not restated the corresponding items of the segment information included within this Report related to the re-allocation of dark fiber contracts from ZB to the ZFS on July 1, 2010, as we have determined that it is impractical to do so.

Our operating costs, excluding depreciation and amortization, increased by $8.8 million, or 14%, from $62.7 million to $71.5 million during the years ended June 30, 2010 and 2011, respectively. The increase in operating costs, excluding depreciation and amortization, primarily relates to the increased costs associated with our acquisition of AGL Networks and merger with AFS during Fiscal 2011 and our organic network expansion efforts. The 14% increase in operating costs, excluding depreciation and amortization, occurred during the same period in which our revenues increased by 44%. The lower ratio of operating costs as compared to revenues is primarily a result of gross installed revenues having a lower component of associated operating costs than the prior period’s revenue base and churned revenue. The ratio also benefited from synergies realized related to our previous acquisitions.

The table below sets forth the components of our SG&A expenses during the years ended June 30, 2011 and 2010, respectively.

Compensation and Benefits Expenses. Compensation and benefits expenses increased by $8.6 million, or 28%, from $31.0 million to $39.7 million during the years ended June 30, 2010 and 2011, respectively. The increase reflects the increased number of employees as our business grew during this period, principally as a result of our acquisition of AGL Networks and merger with AFS in Fiscal 2011. At June 30, 2011 we had 396 full time employees compared to 300 at June 30, 2010.

Network Operations Expenses. Network operations expenses increased by $7.7 million, or 39%, from $19.9 million to $27.6 million during the years ended June 30, 2010 and 2011, respectively. The increase in such expenses principally reflects the growth of our network assets and the related expenses of operating that expanded network following our acquisition of AGL Networks and the AFS merger during Fiscal 2011. The ratio of network operations expenses as a percentage of revenues was consistent during the years ended June 30, 2011 and 2010 at 10%.

Other SG&A. Other SG&A expenses, which includes expenses such as property tax, travel, office expense, and maintenance expense on colocation facilities, increased by $8.1 million, or 59%, from $13.7 million to $21.7 million during the years ended June 30, 2010 and 2011, respectively. The increase is principally from our acquisition of AGL Networks and merger with AFS in Fiscal 2011 and our organic network expansion efforts.

Stock-based compensation expenses increased by $6.1 million, or 34%, from $18.2 million to $24.3 million during the years ended June 30, 2010 and 2011, respectively. The increase is primarily a result of an adjustment in the estimated value of the common units issued to the Company’s employees and directors. As of June 30, 2011, management estimates the value of the Company’s Class A, B, C, D and E common units to be $0.81, $0.58, $0.33, $0.31 and $0.23, respectively compared to a valuation of $0.49, $0.28, $0.03, $0.0 and $0.0, respectively, as of June 30, 2010.

Depreciation and amortization expense increased by $21.8 million, or 56%, from $38.7 million to $60.5 million during the years ended June 30, 2010 and 2011, respectively. The increase is a result of the substantial increase in our capital assets and intangible assets, principally from the AGL Networks acquisition and merger with AFS in Fiscal 2011, and the resulting depreciation and amortization of such capitalized amounts.

Interest expense increased by $14.7 million, or 79%, from $18.7 million to $33.4 million during the years ended June 30, 2010 and 2011, respectively. The increase is primarily a result of our increased indebtedness

associated with our Existing Notes. As of June 30, 2011 we had Existing Notes with a principal amount of $350.0 million, which accrue interest at a notional rate of 10.25%. During the period January 1, 2010 through March 12, 2010, our average debt balance, which consisted of term loans and a revolving line of credit, was $177.5 million. These term loans accrued interest at lower rates ranging from 5.9% to 6.4%. On March 12, 2010, we issued $250 million in Existing Notes which accrued interest at 10.25%. With a portion of the proceeds of the Existing Notes, we repaid our term loans and revolver. Additionally, in September of 2010, we issued an additional $100 million in Existing Notes. The increased average outstanding debt balance during the year ended June 30, 2011 as compared to the year ended June 30, 2010 was the primary cause of the increased interest expense during the period. Partially offsetting the increase in interest expense was $3.7 million of interest which was capitalized during the year ended June 30, 2011 related to our construction projects.

Income tax expense increased over the prior year by $7.7 million from $4.8 million to $12.5 million during the year ended June 30, 2010 and 2011, respectively. Our provision for income taxes includes both the current provision and a provision for deferred income tax expense resulting from timing differences between tax and financial reporting accounting bases. We are unable to combine our NOLs for application to the income of our subsidiaries in some states and thus our state income tax expense is higher than the expected combined rate. In addition, as noted above, we are subject to limits on the amount of carry forward NOLs that we may use each year for federal and state purposes. See “—Factors Affecting Our Results of Operations.” The following table reconciles an expected tax provision based on a statutory federal tax rate of 34% applied to our book net income.

Our revenue was generated from the following business units during the years ended June 30, 2010 and 2009:

Our total revenue increased by $74.0 million, or 59%, from $125.3 million to $199.3 million during the years ended June 30, 2009 and 2010, respectively. The increase is a result of a full year of revenue from our Fiscal 2009 acquisitions being reflected in the Fiscal 2010 results and organic growth.

The stratification of our revenue during the years ended June 30, 2010 and 2009 was consistent with a majority of the revenue recognized during the periods presented resulting from monthly recurring revenue streams. The following table reflects the stratification of our revenues during these periods:

Zayo Bandwidth. Our revenues from our Zayo Bandwidth business unit increased by $53.8 million, or 42%, from $129.3 million during the year ended June 30, 2009 to $183.1 million during the year ended June 30, 2010, principally as a result of increased revenues attributable to our acquisition of FiberNet and the allocation of a portion of the FiberNet assets and legacy business to the Zayo Bandwidth business unit.

zColo. Our zColo business unit, which only began operations in September 2009 following our acquisition of FiberNet, recognized $24.0 million of revenues during the year ended June 30, 2010.

Our operating costs, excluding depreciation and amortization, increased by $24.9 million, or 66%, from $37.8 million to $62.7 million during the years ended June 30, 2009 and 2010, respectively. The increase in operating costs, excluding depreciation and amortization, reflects the increased operating costs of our growing network.

The table below sets forth the components of our SG&A expenses during the years ended June 30, 2010 and 2009, respectively.

Compensation and Benefits Expenses. Compensation and benefits expenses increased by $9.5 million, or 44%, from $21.5 million to $31.0 million during the years ended June 30, 2009 and 2010, respectively. The increase reflects the increased number of employees as our business grew during this period, principally as a result of our acquisition of FiberNet in September of 2009. At June 30, 2010, we had 300 full time employees compared to 218 at June 30, 2009.

Network Operations Expenses. Network operations expenses increased by $2.6 million, or 15%, from $17.3 million to $19.9 million during the years ended June 30, 2009 and 2010, respectively. The increase in such

expenses principally reflected the growth of our network assets and the related expenses of operating that expanded network following our acquisition of FiberNet in September of 2009.

Other SG&A. Other SG&A expenses, which includes expenses such as property tax, travel, office expense, and maintenance expense on colocation facilities, increased by $1.7 million, or 14%, from $12.0 million to $13.7 million during the years ended June 30, 2009 and 2010, respectively. The increase is a result of our acquisition of FiberNet in September of 2009 as well as our organic network expansion efforts.

Transaction Costs. We incurred transaction costs, which principally include expenses incurred in connection with potential and closed acquisitions, of $0.7 million and $1.3 million during the years ended June 30, 2009 and 2010, respectively.

Stock-based compensation expenses increased by $11.8 million, or 183%, from $6.4 million to $18.2 million during the years ended June 30, 2009 and 2010, respectively. The increase is primarily a result of an additional 5.4 million common units vesting during the year ended June 30, 2010 as compared to the year ended June 30, 2009 and an increase in the fair market value of the Class A, B and C common units from $0.16, $0 and $0 per unit, respectively as of June 30, 2009 to $0.49, $0.28 and $0.03 per unit, respectively as of June 30, 2010.

Depreciation and amortization expense increased by $12.2 million, or 46%, from $26.6 million to $38.7 million during the years ended June 30, 2009 and 2010, respectively. The increase is a result of the substantial increase in our capital assets and intangible assets, principally from the FiberNet acquisition in September 2009, and the resulting depreciation and amortization of such capitalized amounts.

The table below sets forth the components of our total other expense, net for the years ended June 30, 2010 and 2009, respectively.

Interest Expense. Interest expense increased by $3.5 million, or 23%, from $15.2 million during the year ended June 30, 2009 to $18.7 million during the year ended June 30, 2010. The increase is a result of the increase in our debt balance beginning in March 2010 as a result of the offering of $250.0 million of Existing Notes and the higher interest rate (10.25%) associated with the Existing Notes. This increase was partially offset by the decline in the LIBOR rates during the nine months ended March 31, 2010 as compared to Fiscal 2009 as the interest rate on our term loans, which were paid off with proceeds from the offering of the Existing Notes in March 2010, was adjustable based on the LIBOR rate. Interest expense associated with our interest rate swaps was $0.7 million in Fiscal 2010 compared to $3.1 million in Fiscal 2009.

Other Income. During the year ended June 30, 2010 the Company recognized a reduction in the price we originally paid for the Onvoy acquisition. We received $0.8 million from the Onvoy purchase escrow account

during the period when such amount was released from escrow. In accordance with ASC 805-10, the Company recognized the release from escrow as other income as the release was outside of the one year acquisition accounting true-up period.

Loss on Extinguishment of Debt: A portion of the proceeds from our issuance in March 2010 of $250.0 million in principal amount of Existing Notes was used to pay off all of our then-outstanding term loans. Upon the termination of the term loans, the Company wrote off the unamortized portion of the debt issuance costs associated with those loans resulting in a loss on extinguishment of debt of $5.9 million.

Income tax expense increased over the prior year by $7.1 million from a benefit of $2.3 million to a provision of $4.8 million during the years ended June 30, 2009 and 2010, respectively. Our provision for income taxes includes both the current provision and a provision for deferred income tax expense resulting from timing differences between tax and financial reporting accounting bases. We are unable to combine our NOLs for application to the income of our subsidiaries in some states and thus our state income tax expense is higher than the expected combined rate. In addition, as noted above, we are subject to limits on the amount of carry forward NOLs that we may use each year for federal and state purposes. See “—Factors Affecting Our Results of Operations.” The following table reconciles an expected tax provision based on a statutory federal tax rate of 34% applied to our book net income.

Reconciliation from net cash provided by continuing operating activities to Adjusted EBITDA

Our primary sources of liquidity have been cash provided by operations, equity contributions, and borrowings. Our principal uses of cash have been for acquisitions, capital expenditures, and debt-service requirements. See “—Cash flows,” below. We anticipate that our principal uses of cash in the future will be for acquisitions, capital expenditures, working capital, and debt service.

As of March 31, 2012, we have financial covenants under the agreements governing each of our Existing Revolving Credit Facility, our Existing Term Loan Facility, and our Existing Notes that, under certain circumstances, restrict our ability to incur additional indebtedness. Among other limitations, the financial covenants contained in the agreements governing our Existing Revolving Credit Facility and Existing Term Loan Facility prohibit us from maintaining total secured indebtedness of more than 4.5 times our previous quarter’s annualized modified EBITDA (which is materially consistent with our Adjusted EBITDA definition). In addition, the indenture governing our Existing Notes limits any increase in our secured indebtedness (other than certain forms of secured indebtedness expressly permitted under the indenture governing the Existing Notes) to a pro-forma secured debt ratio of 3.5 times our previous quarter’s annualized modified EBITDA and limits our incurrence of additional indebtedness to a total indebtedness ratio of 4.25 times our previous quarter’s annualized modified EBITDA.

As of March 31, 2012, we had $17.2 million in cash and cash equivalents. Cash and cash equivalents consist of amounts held in bank accounts and highly-liquid U.S. treasury money market funds. Working capital (current assets less current liabilities) at March 31, 2012 was a deficit of $31.8 million. Although we have a working capital deficit as of March 31, 2012, a large portion of the deficit is a result of the current portion of our deferred revenue balance of $22.8 million that we will be recognizing as revenue over the next twelve months. The actual cash outflows associated with fulfilling this deferred revenue obligation during the next twelve months will be significantly less than the March 31, 2012 current deferred revenue balance. As of March 31, 2012, we had $63.8 million available under our Existing Revolving Credit Facility, which can be used to satisfy any short-term obligations.

Our net capital expenditures increased by $15.1 million, or 17%, during the nine months ended March 31, 2012 as compared to the nine months ended March 31, 2011, from $87.7 million to $102.8 million (net of stimulus grants), respectively. Our net capital expenditures increased by $53.7 million, or 91%, during the year ended June 30, 2011 as compared to the year ended June 30, 2010, from $58.8 million to $112.5 million (net of stimulus grants), respectively. Our capital expenditures primarily relate to success-based contracts. The increase in capital expenditures is a result of meeting the needs of our increased customer base resulting from our acquisitions and organic growth. We expect to continue to invest in our network (in part driven by fiber-to-the-tower activities) 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 (including available borrowings under our revolving credit facility), equity contributions, and available cash on hand.

We believe that our cash flow from operating activities, in addition to cash and cash equivalents currently on-hand, will be sufficient to fund our operating activities 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 review acquisitions and additional strategic opportunities, including large acquisitions, which may require additional debt or equity financing.

Nine Months Ended March 31, 2012 Compared to the Nine Months Ended March 31, 2011

The following table sets forth components of our cash flow for the nine months ended March 31, 2012 and 2011.

Net cash flows from operating activities increased by $35.8 million, or 66%, from $54.6 million to $90.4 million during the nine months ended March 31, 2011 and 2012, respectively. Net cash flows from operating activities during the nine months ended March 31, 2012 represents our net loss of $0.6 million, plus the add back to our net earnings of non-cash items deducted in the determination of net earnings, principally depreciation and amortization of $60.7 million, the deferred tax provision of $19.1 million and non-cash stock-based compensation expense of $19.7 million, plus the change in working capital components.

Net cash flows from operating activities during the nine months ended March 31, 2011 represents our net loss from continuing operations of $16.0 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 $43.9 million, the deferred tax provision of $4.9 million and non-cash stock-based compensation expense of $28.8 million, plus the change in working capital components.

The increase in net cash flows from operating activities during the nine months ended March 31, 2012 as compared to March 31, 2011 is primarily a result of additional earnings and synergies realized from our acquisitions of AGL Networks, AFS, 360networks and MarquisNet and organic growth. Offsetting the increase to cash flows from operating activities during the nine months ended March 31, 2012 as compared to the nine months ended March 31, 2011 were net cash outflows during the fiscal 2012 period of approximately $26.0 million related to payments made against the net working capital deficiency assumed in the 360networks acquisition.

We used cash in investing activities of $271.3 million and $436.1 million during the nine months ended March 31, 2011 and 2012, respectively. During the nine months ended March 31, 2012, our principal uses of cash for investing activities were $317.9 million for the acquisition of 360networks, $15.5 million for our acquisition of MarquisNet and $102.8 million in additions to property and equipment, net of stimulus grant reimbursements.

During the nine months ended March 31, 2011, our principal uses of cash in investing activities was our $73.7 million purchase of AGL Networks, our $110.0 merger with AFS and $87.6 million in additions to network-related equipment, net of stimulus grant reimbursements.

Our net cash provided by financing activities was $138.4 million and $337.6 million during the nine months ended March 31, 2011 and 2012, respectively. Our cash flows from financing activities during the nine months ended March 31, 2012 comprise $335.6 million from the proceeds from long-term borrowings, $1.4 million in

equity contributions from Holdings and a $10.9 million advance from CII. This cash inflow was partially offset by $9.0 million in debt issuance costs, $0.4 million in transfers of cash to restricted cash accounts and $0.8 million in principal payments on capital leases during the period.

Our cash flows from financing activities during the nine months ended March 31, 2011 primarily comprise $103.0 million in cash proceeds from our September 2010 Existing Notes offering, $35.5 million in equity contributions from CII, and $0.8 million in transfers of cash from restricted cash accounts. These cash inflows were partially offset by $4.1 million in deferred financing costs and $1.4 million in principal payments on capital leases during the period.

The following table sets forth components of our cash flow for the years ended, 2011, 2010, and 2009.

Net cash flows from operating activities increased by $38.9 million, or 67%, from $58.2 million to $97.1 million during the years ended June 30, 2010 and 2011, respectively. Net cash flows from operating activities during the year ended June 30, 2011 represents our loss from continuing operations of $5.0 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 $60.5 million, the deferred tax provision of $11.1 million and non-cash stock-based compensation expense of $24.3 million, plus the change in working capital components.

Net cash flows from operating activities during the year ended June 30, 2010 represents our loss from continuing operations of $14.0 million, plus the add back to our net earnings of non-cash items deducted in the determination of net income, principally depreciation and amortization of $38.7 million, the deferred tax provision of $5.4 million, non-cash stock-based compensation expense of $18.2 million and our loss on extinguishment of debt of $5.9 million, plus the change in working capital components.

The increase in net cash flows from operating activities during Fiscal 2011 is a result of the increase in earnings recognized associated with our acquisitions during Fiscal 2011 and organic growth.

We used cash in investing activities of $296.2 million and $155.3 million during the years ended June 30, 2011 and 2010, respectively. During the year ended June 30, 2011, our principal uses of cash in investing activities were our $73.7 million purchase of AGL Networks, our $110.0 merger with AFS and $112.5 million in additions to property and equipment, net of stimulus grant reimbursements.

During the year ended June 30, 2010, our principal uses of cash in investing activities were our $96.6 million purchase of FiberNet and $58.8 million in additions to network-related equipment.

Our net cash provided by financing activities was $134.2 million and $135.4 million during the years ended June 30, 2011 and 2010, respectively. Our cash flows from financing activities during the year ended June 30,

2011 primarily comprise $103.0 million in cash proceeds from our September 2010 Existing Notes offering and $36.5 million in equity contributions from CII. These cash inflows were offset by $4.1 million in deferred financing costs and $1.7 million in principal payments on capital leases during the period.

Our cash flows from financing activities during the year ended June 30, 2010 primarily consisted of $39.8 million from equity contributions, $246.9 million in net proceeds from our March 2010 Note offering and $30 million in net proceeds on a term loan entered into in order to finance the FiberNet acquisition. These financing inflows were offset by the repayment of our outstanding term loans totaling $166.2 million, debt issuance costs incurred during the period of $12.4 million, $2.2 million in capital lease principal payments, and $0.6 million in transfers of cash to restricted cash accounts.

The following table represents a summary of our estimated future payments under contractual cash obligations as of March 31, 2012. 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 payments.

Our purchase commitments are primarily success-based; that is, we have executed customer contracts that support the future capital expenditures. These purchase commitments exclude commitments related to stimulus projects in which we will be reimbursed for such expenditures. The contractual long-term debt payments, above, include an estimate of future interest expense based on the interest rate in effect on our floating rate debt obligations as of the most recent balance sheet date.

We do not have any off-balance sheet arrangements other than our operating leases. We do not participate in transactions that generate relationships with unconsolidated entities or financial partnerships, such as entities often referred to as structured finance or special purpose entities, which would have been established for the purpose of facilitating off-balance sheet arrangements.

In August 2011, the FASB issued guidance that allows companies to consider qualitative factors when testing goodwill for impairment. Current GAAP requires an entity to perform a two-step test in which the first step involves calculating the fair value of goodwill and comparing it to the carrying value. The recently issued guidance allows an entity to assess qualitative factors to determine whether it is more likely than not that the fair value exceeds the carrying value prior to performing the two step evaluation. If it is determined that it is unlikely that the carrying value exceeds the fair value, then the entity is no longer required to complete the two step goodwill impairment evaluation. We are considering the early adoption of this new guidance in fiscal 2012 and do not believe the adoption would have a material impact on our consolidated results of operations or financial condition.

We have reviewed all other new accounting pronouncements and believe they will not have a material impact on our financial statements.

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 July 10, 2012, we had outstanding approximately $750 million of our Secured Notes, $500 million of our Unsecured Notes, $1,620 million under our New Term Loan Facility, $4.4 million in a seller note due to the former owners of AFS, and $3.8 million of capital lease obligations (collectively, our “Existing Indebtedness”). As of July 10, 2012, we had $250 million available for borrowing under our $250 million New Revolving Credit Facility. The carrying value of our Existing Indebtedness based on current market interest rates for debt of similar terms and average maturities approximates the fair value.

Our Secured Notes and Unsecured Notes accrue interest at fixed rates of 8.125% and 10.125%, respectively. Both our New Revolving Credit Facility and our New Term Loan Facility accrue interest at floating rates subject to certain conditions. As of July 10, 2012, the applicable interest rate on our New Revolving Credit Facility was 5.62% and the rate on our New Term Loan Facility was 7.125%. A hypothetical increase in the applicable interest rate on our New Term Loan Facility of one percentage point would increase our annual interest expense by approximately $16.2 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.

With our recent acquisition of AboveNet, we will have exposure to market risk arising from foreign currency exchange rates. During the year ended December 31, 2011, AboveNet’s foreign activities accounted for 9.5% of its consolidated revenue. Due to the strengthening of the British pound compared to the U.S. dollar, the translation rate for the year ended December 31, 2011 increased 3.7% compared to the translation rate used for the year ended December 31, 2010.

Effective with the closing of the AboveNet Acquisition, we monitor foreign markets and our commitments in such markets to manage currency and other risks. To date, we have not entered into any hedging arrangement designed to limit exposure to foreign currencies. Because of our European expansion, our level of foreign activities is expected to increase and if it does, we may determine that such hedging arrangements would be appropriate and we will consider such arrangements to minimize risk.

We are a provider of bandwidth infrastructure and network-neutral colocation and interconnection services, which are key components of telecommunications and Internet infrastructure services. These services enable our customers to manage, operate, and scale their telecommunications and data networks and data center related operations. We provide our bandwidth infrastructure services over our dense regional and metropolitan fiber networks, enabling our customers to transport data, voice, video, and Internet traffic, as well as to interconnect their networks. Our bandwidth infrastructure services are primarily used by wireless service providers, carriers and other communications service providers, media and content companies, and other bandwidth-intensive enterprises. We typically provide our lit bandwidth infrastructure services for a fixed-rate monthly recurring fee under long-term contracts, which are usually average more than three years in length (and average approximately six years for fiber-to-the-tower services). Our dark fiber contracts are generally longer term in nature, averaging approximately twelve years in length. Our network-neutral colocation and interconnection services facilitate the exchange of voice, video, data, and Internet traffic between multiple third-party networks.

As of March 31, 2012, our fiber networks spanned approximately 45,673 route miles and 2,018,677 fiber miles, served 164 geographic markets in the United States, and connected to 5,431 buildings, including 2,427 cellular towers, allowing us to provide our bandwidth infrastructure services to our customers over redundant fiber facilities between key customer locations. The majority of the markets that we serve and buildings to which we connect have few other networks capable of providing similar bandwidth infrastructure services, which we believe provides us with a sustainable competitive advantage in these markets. As a result, we believe that the services we provide our customers would be difficult to replicate in a cost- and time-efficient manner. We provide our network-neutral colocation and interconnection services utilizing our own data centers located within three major carrier hotels in the important gateway markets of New York and New Jersey and in facilities located in Chicago, Illinois; Las Vegas, Nevada; Los Angeles, California; Nashville, Tennessee; Plymouth, Minnesota; Cincinnati, Ohio; Cleveland, Ohio; Columbus, Ohio; Pittsburgh, Pennsylvania; and Memphis, Tennessee.

We were founded in 2007 in order to take advantage of the favorable Internet, data, and wireless growth trends driving the demand for bandwidth infrastructure services. These trends have continued in the years since our founding, despite volatile economic conditions, and we believe that we are well-positioned to continue to capitalize on those trends. We have built our network and services through 20 acquisitions and asset purchases for an aggregate purchase consideration, net of cash acquired, of $3,036.2 million (after deducting our acquisition cost for Onvoy Voice Services (“OVS”) and Zayo Enterprise Networks (“ZEN”), two business units which we spun-off to our parent in March of 2010 and April of 2011, respectively; see “—Our Business Units”). We have invested $241.4 million (after deducting that portion of our equity capital that we used to fund our acquisition of OVS and ZEN) of equity capital to fund these acquisitions. Some of our most significant acquisitions to date have been:

See “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Factors Affecting Our Results of Operations—Business Acquisitions” for additional information regarding our acquisitions and asset purchases since inception.

We are organized into three business units: Zayo Bandwidth (“ZB”), zColo and Zayo Fiber Solutions (“ZFS”). Each business unit is structured to provide sales, delivery, and customer support for its specific telecom and Internet infrastructure services.

Zayo Bandwidth. Through our ZB unit, we provide bandwidth infrastructure services over our metropolitan and regional fiber networks. These services are typically lit bandwidth, meaning that we use optronics to “light” the fiber, and consist of private line, wavelength, Ethernet, and IP services. Our target customers within this unit are primarily wireless service providers, carriers and other communications service providers (including ILECs, IXCs, RLECs, CLECs, and foreign carriers), media and content companies, cable and satellite video providers, and other Internet-centric businesses that require an aggregate minimum of 10 Gbps of bandwidth across their networks.

zColo. Through our zColo unit, we provide network-neutral colocation and interconnection services in three major carrier hotels in the New York metropolitan area (60 Hudson Street and 111 8th Avenue in New York, New York, and 165 Halsey Street in Newark, New Jersey) and in facilities located in Chicago, Illinois; Las Vegas, Nevada; Los Angeles, California; and Nashville, Tennessee. As a result of the restructuring of our business units, in January 2011, ZEN and ZB transferred five facilities to zColo located in Plymouth, Minnesota; Cincinnati, Ohio; Cleveland, Ohio; Columbus, Ohio; Pittsburg, Pennsylvania; and Memphis, Tennessee. In July, ZB transferred an additional colocation facility located in Pittsburgh, Pennsylvania to zColo. In addition, we are the exclusive operator of the Meet-Me Room at 60 Hudson Street, which is one of the most important carrier hotels in the United States with approximately 300 domestic and international networks interconnecting within this facility. Our zColo data centers house and power Internet and private-network equipment in secure, environmentally-controlled locations that our customers use to aggregate and distribute data, voice, Internet, and video traffic. Throughout two of the three facilities in the New York City metropolitan area, we operate intra-building interconnect networks that, along with the Meet-Me Room at 60 Hudson Street, are utilized by our customers to efficiently and cost-effectively interconnect with other Internet, data, video, voice, and wireless networks. As of March 31, 2012 and June 30, 2011, the zColo unit managed 94,175 and 72,927 square feet of billable colocation space, respectively.

Zayo Fiber Solutions. The ZFS unit was formally launched on July 1, 2010, after our acquisition of AGL Networks, a company whose business was comprised solely of dark fiber-related services. See “—Factors Affecting Our Results of Operations—Business Acquisitions—Acquisition of AGL Networks, LLC (“AGL Networks”).” Through our ZFS unit, we provide dark fiber and related services primarily on our existing fiber footprint. We lease dark fiber pairs to our customers and, as part of our service offering, we manage and maintain the underlying fiber network for the customer. Our customers light the fiber using their own optronics, and as such, we do not manage the bandwidth that the customer receives. This allows the customer to manage bandwidth on their own metropolitan and long haul networks according to their specific business needs. ZFS’s customers include carriers and other communication service providers, Internet service providers, wireless service providers, major media and content companies, large enterprises, and other companies that have the expertise to run their own fiber optic networks. We market and sell dark fiber-related services under long-term contracts (averaging approximately twelve years in length); our customers generally pay us on a monthly basis for these services.

Below is a summary of the key services provided by our three business units, the types of customers we target and our representative peer groups that offer comparable services:

See Note 18 to our 2011 audited consolidated financial statements included in this prospectus for financial information by business unit.

Our primary business objective is to be the preferred provider of bandwidth infrastructure and network-neutral colocation and interconnection services within our target markets. The following are the key elements to our strategy for achieving this objective:

Specifically Focus on Bandwidth Infrastructure and Colocation Services. Bandwidth infrastructure and network-neutral colocation and interconnection services are critical network components in the delivery of communications services (including Internet connectivity, wireless voice and data, content delivery and voice and data networks) by communications service providers to their end users. We believe our disciplined approach and specific focus on providing these critical services to our targeted customers enable us to provide a high level of customer service while at the same time being responsive to changes in the marketplace.

Selectively Expand Through Acquisitions. We have made numerous acquisitions since our founding and we will continue to evaluate potential acquisition opportunities. 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 have consistently demonstrated that we are able to acquire and effectively integrate companies and organically grow revenue and EBITDA post-acquisition. Acquisitions have the ability to increase the scale at which we operate, which in turn affords us the ability to increase our operating leverage, extend our network reach, and broaden our customer base. We will continue to evaluate potential acquisitions, both small and large, on a number of criteria, including the quality of the infrastructure assets, the fit within our existing businesses, the opportunity to expand our network, and the opportunity for us to create value as a result of the acquisition. See “Risk Factors—Future acquisitions are a component of our strategic plan, and will include integration and other risks that could harm our business.”

We classify the communications services industry into four distinct categories: enablers of infrastructure, telecom and Internet infrastructure service providers, communications service providers, and end users. Bandwidth infrastructure services and colocation and interconnection services are components of telecom and Internet infrastructure services.

We are a provider of bandwidth infrastructure and colocation services, a subset of telecom and Internet infrastructure services. We provide the following services:

Nearly all communications service providers utilize one or more forms of telecom and Internet infrastructure services in order to provide services such as Internet connectivity, wireless voice and data services, CDN services, hosting services, local and long distance voice networks, HDTV networks and data networks. These services are typically offered by ILECs, RLECs, hosting companies, wireless service providers, IXCs, CLECs, CATV, satellite TV, and CDN service providers.

In recent years, the industry has experienced significant increases in global IP traffic. The growth in Internet traffic overall is being driven by a mix of consumer and business trends including the proliferation of wireless

smart phones, rich media such as video on demand, real time online streaming video, social networks, online gaming, cloud computing, 3G and 4G mobile broadband cards and the trend towards enterprise outsourcing of IT and storage needs.

Growth in demand of telecom and Internet infrastructure services is also likely to continue to come from private data networks or those networks that do not utilize the Internet. Such networks have many uses including executing trades and backing up data for the major financial exchanges, securely transferring corporate and government information, conducting high definition video calls, supporting federal medical privacy regulations (HIPPA) compliance when sending patient medical x-rays electronically, and backing up or storing other critical data. Services sold by bandwidth infrastructure providers are commonly used to support these data networks.

In recent years, there have been numerous acquisitions of companies that provide bandwidth infrastructure services in the United States. We believe our industry will continue to consolidate, resulting in a decrease in the number of bandwidth infrastructure providers. At the same time, we anticipate that demand for bandwidth will continue to increase, positively impacting businesses that provide bandwidth infrastructure services.

Our telecom and Internet infrastructure assets consist of our fiber networks (including our fiber-to-the-tower networks), the optronics that we use to provide our bandwidth infrastructure services over our fiber networks, and our data centers where we provide network-neutral colocation and interconnection services.

The vast majority of our fiber networks are owned or operated under long-term indefeasible right of use (“IRU”) contracts, span 45,673 route miles, and connect to 164 geographic markets in the United States. Within the markets that we serve, our network connects to 5,431 buildings, including major data centers, carrier hotels and central offices, single-tenant high-bandwidth locations, cellular towers and enterprise buildings. Our networks are designed in such a way that ample opportunity exists to organically add additional markets and buildings to our networks; we are focused on adding markets and buildings that have limited or no existing bandwidth infrastructure providers. Our fiber networks also have the following key attributes:

Regional fiber networks. We use our regional fiber networks to provide bandwidth infrastructure services between markets that we serve. Our regional networks are commonly used in the following scenarios: First, to provide service between on-net buildings (or buildings that are directly connected to our fiber network), that are located in different large markets, for example, Chicago and New York. Second, to connect our on-net buildings in small and midsized markets back to major data centers, wireless switching centers, carrier hotels and ILEC central offices in larger markets, for example, between Lima, Ohio and Cleveland, Ohio. Occasionally our networks provide service between on-net buildings in two different small or midsized 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 markets to our regional networks on a success basis, meaning that we attempt primarily to invest capital only when the terms of a customer contract provide an attractive return on our investment. We have deployed current generation DWDM technologies across most of our regional networks which are capable of scaling to multiple terabytes of bandwidth, which allow us to continue to add capacity as demand for bandwidth increases. We expect technology to continue to advance and that we will augment our regional networks accordingly.

Fiber-to-the-tower networks. We operate fiber-to-the-tower networks in 53 distinct geographic areas across our footprint and have fiber-to-the-tower projects under construction in four additional markets. We connect to 2,427 cellular towers and have contracts with multiple national wireless carriers to build out to 597 additional towers. These fiber-to-the-tower networks provide our customers with bandwidth infrastructure services that offer significantly improved performance over legacy copper networks. Our fiber-to-the-tower networks are scalable, which means that we can increase the amount of bandwidth that we provide to each of the towers as our customers’ wireless data networks grow. Our fiber-to-the-tower markets are generally in areas where we already have dense networks, which afford us the ability to offer ring-protected fiber-to-the-tower services. As such, we are able to offer a higher service level agreement than those traditionally offered over legacy unprotected microwave and copper networks.

Our fiber-to-the-tower networks have the ability to provide significantly more bandwidth to a given tower than copper and microwave networks. We believe that bandwidth used on our fiber-to-the-tower networks will grow over time as smart phone penetration increases, tablet computers and readers are adopted, wireless 3G and 4G laptop cards are more broadly used, video consumption increases on mobile devices, and 3G networks are upgraded to 4G networks, including LTE and WiMax networks.

Diverse portfolio of on-net buildings. We provide service to over 5,400 on-net buildings and are continually making capital investments to increase our on-net building footprint. On-net buildings are buildings that directly connect via fiber to our metropolitan or regional fiber 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 are primarily composed of the following:

Our key colocation 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, New York and 165 Halsey Street in Newark, New Jersey. zColo also has the exclusive right to operate and provide colocation and interconnection services in the Meet-Me Room at 60 Hudson Street, although carriers may inter-connect there in less cost-effective manners including without using the Meet-Me-Room. We also have colocation facilities located in Chicago, Illinois; Las Vegas, Nevada; Los Angeles, California; Nashville, Tennessee; Plymouth, Minnesota; Cincinnati, Ohio; Cleveland, Ohio; Columbus, Ohio; Pittsburgh, Pennsylvania; and Memphis, Tennessee. All of our colocation facilities are network-neutral and have backup power in the form of batteries and generators, air conditioning, modern fire suppression equipment and ample power to meet customer needs. We have long-term leases with the owners of each of the buildings where we provide colocation services. Our colocation facilities total approximately 94,175 net square feet of billable data center space.

Our primary network operations center (“NOC”) is located in Tulsa, Oklahoma and provides 24-hour, 365-day monitoring and network surveillance. 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.

We have the necessary right-of-way agreements and other required rights, including state and federal government authorization, that allow us to maintain and expand our fiber networks which 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 right-of-way agreements under long-term contracts.

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 the members’ equity contributions, borrowings under our credit agreement, and cash provided by operating activities.

Zayo Bandwidth. Through our Zayo Bandwidth unit, we offer bandwidth infrastructure services over our fiber network. These service offerings are targeted to meet the needs of the largest consumers of bandwidth infrastructure in the United States. Services are primarily provided under contracts with terms ranging from three to six years and typically include a monthly recurring charge and in many cases an installation fee. The monthly recurring fee is fixed in most cases and is based on the amount of bandwidth provided and the type of locations to which the bandwidth connects.

Bandwidth infrastructure services typically include (i) private line services that range in speed, or bandwidth provided, from 45 Mbps to 10 Gbps and include DS-1, DS-3, OC-3, OC-12, OC-48 and OC-192 services; (ii) Ethernet services that range in speed from 100 Mbps to 10 Gbps; (iii) wavelength services that are provided at 2.5 Gbps and 10 Gbps speeds; (iv) IP services that can range from 10 Mbps to 10 Gbps; and (v) fiber-to-the-tower services. ZB offers several configurations of these services. These configurations include simple point-to-point (or building-to-building) services and more complex point-to-multi-point or multi-point-to-multi-point services. We also custom-tailor complex network solutions for our largest customers, including customized low latency routing, multi-hundred location fiber-to-the-tower networks, and other similarly customized deployments.

All services are provided over modern fiber optic cable and are monitored by our 24-hour, 365-day NOC. A majority of our services are provided end-to-end exclusively over our fiber network, which provides many benefits including:

ZB is an active participant in federal broadband stimulus projects available through the Broadband Technology Opportunity Program and the American Recovery and Reinvestment Act. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Overview—Recent Developments—Broadband Stimulus Awards.”

zColo. Through our zColo business unit, we provide network-neutral colocation, interconnection and other services.

Colocation Services. Our facilities provide our customers with secure, reliable, and environmentally-controlled data center space. Our colocation services include redundant power and cooling, physical security, fire suppression and remote hands services. Each of our colocation facilities is managed by experienced and well-trained technicians and monitored from our network control center based in New York, New York. We typically provide our services for an installation fee and a recurring monthly fee and generally provide them on one- to five-year contracts.

Zayo Fiber Solutions. Through our ZFS unit, we provide dark fiber-related services to customers who desire to operate their telecommunications and data networks at the fiber level, in those markets where we have fiber inventory in excess of our needs. These include customers from Zayo Bandwidth, as well as from the legacy 360 networks, AFS and AGL Networks businesses, and range from large wireless carriers to local municipalities. Dark fiber related services generally consist of the following:

Our business primarily engages in direct sales without the use of agents or resellers. Our sales organization consists of 38 sales representatives, 36 of which report into a common sales group and the remaining two report directly to the zColo business unit and specialize in selling colocation and interconnect services. Each of these sales representatives is responsible for meeting a monthly quota. The primary sales organization sells services across all three business units and products. The sales representatives are directly supported by sales management, engineering, solutions engineering and marketing staff.

The main sales organization is organized into five sales channels that align around both region and customer segment. Each of these channels maintains dedicated sales and solutions engineering support resources. Three channels focus on the eastern, Midwestern and western geographic regions of the United States, primarily supporting regional carriers and medium to large enterprise customers, particularly in the healthcare, education, media and financial sectors. The other two channels focus on the national wireline and wireless carriers, also selling across our complete product set.

Our zColo sales force is located in various markets and is focused on existing customers who are located within our colocation facilities that require additional interconnection or colocation services, and on new customers that require colocation services in the major carrier hotels and data centers in the United States.

Separate from the sales groups, we have a corporate marketing group that is responsible for the Company’s marketing efforts. The marketing staff manages our web presence, customer facing mapping tools, marketing campaigns, and public relations. The sales organization is further supported by product management groups that are focused on the dark fiber, wavelengths, private line, Ethernet, IP, colocation, and fiber-to-the-tower product groups.

Our customers generally have a significant and growing need for the telecom and Internet 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 such as companies in the education, healthcare, financial services, and technology industries. Our largest single customer accounted for approximately 14% of our monthly recurring revenue during the nine months ended March 31, 2012, and total revenues from our top ten customers accounted for approximately 50% of our monthly recurring revenue during the same period. We currently depend, and expect to continue to depend, upon a relatively small number of customers for a significant percentage of our revenue. If any of our key customers experience a general decline in demand due to economic or other forces, or if any such customer is not satisfied with our services, such key customer may reduce the number of service orders it has with us, terminate its relationship with us (subject to certain early termination fees), or fail to renew its contractual relationship with us upon expiration.

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.

We have numerous customer orders for connections, including contracts with multiple national wireless carriers, to build out to more than 597 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.

Bandwidth Infrastructure. We believe that among the key factors that influence our customers’ choice of bandwidth infrastructure providers are the ability to provide our customers with a service that exclusively utilizes our fiber network from end-to-end, the quality of the service the customer receives, the ability to implement a complex custom solution to meet the customer’s needs, the price of the service provided, and the ongoing customer service provided.

Generally, price competition in non-commoditized geographies is less intense than that for commoditized routes. 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. Typically, these competitors are large, well-capitalized ILECs such as AT&T Inc., CenturyLink, Inc. and Verizon Communications Inc., or are publicly traded bandwidth infrastructure providers such as AboveNet (prior to the consummation of the AboveNet Acquisition), and Level 3 Communications, Inc. In certain geographies, privately held companies can also offer comparable fiber-based solutions. On occasion, the price for bandwidth infrastructure services is too high compared with the cost of lower-speed, copper-based telecom services. We believe that price competition will continue in situations where our competitors have comparable pre-existing fiber networks. Some of our competitors have long-standing customer relationships, very large enterprise values, and significant access to capital. In addition, several of our competitors have large, pre-existing expansive fiber networks.

Colocation. The market for our colocation and interconnection services is very competitive. We compete based on price, quality of service, network-neutrality, type and quantity of customers in our data centers, and location. We compete against large, well-established colocation providers who have significant enterprise values, and against privately-held, well-funded companies. Given that certain companies are privately held, we are unable to effectively calculate our market share.

Some of our competitors have longer-standing customer relationships and significantly greater access to capital, which may enable them to materially increase data center 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 nationally and are able to attract a customer base that values and requires national reach and scale.

We compete with other interconnection and colocation service providers including Equinix, Inc., The Telx Group, Inc., Terremark Worldwide, Inc. (a Verizon Communications, Inc. subsidiary), Level 3 Communications, Inc., and Savvis, Inc. (a CenturyLink Inc. subsidiary) among others. These companies offer similar services and operate in the markets where we provide service.

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 such pending litigation matters will not have a material adverse effect upon our results of operations or our consolidated financial condition.

In December 2011, a lawsuit was filed by Idacorp, Inc. (“Idacorp”) against AFS Inc. in the United States District Court for the District of Idaho. On October 1, 2010, we completed a merger with American Fiber Systems Holdings Corporation, the parent company of AFS. On October 12, 2006, Idacorp and AFS entered into a stock purchase agreement under which Idacorp, Inc. agreed to sell to AFS 100% of the equity interest in Idacomm, a provider of telecommunications services and commercial Internet services in Idaho and Nevada, for a purchase price of $10.0 million subject to certain post-close adjustments. Per the terms of the stock purchase agreement there was a holdback clause which allowed AFS to hold back $2.0 million of the purchase price to satisfy certain indemnification claims. The holdback was established in 2006 as both Idacorp and AFS were aware of a potential indemnification claim which could be imposed by the City of Las Vegas which would require certain aerial fibers owned by Idacomm to be relocated to underground locations in the Las Vegas, Nevada area. In 2009 (and then again in 2010), AFS notified Idacorp of indemnification claims against the holdback related to the City of Las Vegas’s “Project Clear Skies” and other matters. Project Clear Skies is a plan for relocating aerial utilities to underground locations in the Las Vegas area. As the indemnification claims are valid and were received within the holdback period, we do not believe the lawsuit filed by Idacorp has merit and as such have not accrued for the $2 million holdback. As of March 31, 2012, no loss contingencies have been accrued for related to this lawsuit. We have an accrued liability of $2.8 million within other liabilities on our condensed consolidated balance sheet as of March 31, 2012, which represents the estimated cost associated with relocating the legacy Idacomm aerial fibers in the Las Vegas area to underground locations as would be required under the Project Clear Skies initiative.

In late March 2012, shareholder plaintiffs brought three purported class and/or derivative claims challenging the AboveNet Acquisition. Two actions were filed in Westchester County, New York Supreme Court: Wachsler v. AboveNet, Inc., et al. and Raul v. LaPerch, et al.; and one action was filed in Chancery Court in Delaware, Miramar Firefighters Pension Fund v. AboveNet, Inc., et al. The Delaware plaintiffs filed an amended complaint on April 17, 2012 and the Westchester actions were stayed by agreement in favor of the Delaware action through June 20, 2012. All three actions allege that AboveNet and its directors breached their fiduciary duties by failing to garner a higher price for AboveNet by engaging in a flawed sales process and by agreeing to inappropriate deal terms, including the go-shop and termination fee provisions. The actions also assert that AboveNet and the Company aided and abetted those purported breaches by entering into the AboveNet Acquisition Agreement, rendering substantial assistance to the AboveNet board of directors in connection with the breaches, and acting with knowledge of, or with reckless disregard to, the individual defendants’ breaches of fiduciary duty. The Raul and Miramar Firefighters Pension Fund actions further allege that the merger sub, Voila Sub, Inc., also aided and abetted those purported breaches. The Delaware plaintiffs had sought a preliminary injunction to alter and delay the transaction in the Miramar Firefighters Pension Fund action but withdrew their application. Plaintiffs now contend they will pursue a money damages claim.

Our operations require that certain of our subsidiaries hold licenses, certificates, and/or other regulatory authorizations from the Federal Communications Commission (“FCC”) and various state Public Utilities Commissions (“PUCs”), all of which we have obtained and maintain in the normal course of our business. The FCC and State PUCs generally have the power to modify or terminate a carrier’s authority to provide regulated wireline services for failure to comply with certain federal and state laws and regulations, and may impose fines or other penalties for violations of the same, and the State PUCs typically have similar powers with respect to the intrastate services we provide under their jurisdiction. In addition, we are required to submit periodic reports to the FCC and the State PUCs documenting interstate and intrastate 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 certain of 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, and local 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 and State PUC proceedings, that such regulations will not have a material adverse effect on us.

Our Audit Committee is currently composed of Mr. Connor, Mr. Cashman, and Mr. Siegel, each of whom is a non-employee member of the board.

We have adopted a written code of conduct that serves as the code of ethics applicable to our directors, officers, and employees, including our principal executive officer and senior financial officers, in accordance with Section 406 of the Sarbanes-Oxley Act of 2002 and the rules of the SEC. In the event that we make any changes to, or provide any waivers from, the provisions of our code of conduct applicable to our principal executive officer and senior financial officers, we intend to disclose these events on our website or in a report on Form 8-K within four business days of such event. This code of conduct is available in the “Corporate Governance” section of our website at http://investor.zayo.com/corporate-governance.

Our Compensation Committee is currently comprised of Michael Choe and John Siegel, each of whom is a non-employee member of the board. The Compensation Committee is responsible for, among other things:

The following Compensation Discussion and Analysis describes the material elements of compensation for our executive officers. When we refer to “executive” in this section, we mean our five executives listed in the Summary Compensation Table, below.

The objective of our compensation practices is to attract, retain, and motivate the highest quality employees and executives who share our core value of enhancing equity-holder value. We believe that the primary goal of management is to create value for our stakeholders and we have designed our compensation program around this philosophy. Substantially all of our employees have a material portion of their compensation tied to the Company’s performance, and a large portion of the overall compensation of our executives is comprised of long-term compensation.

The components of compensation for our executives are base salary, quarterly non-equity incentive compensation, equity participation, and benefits. In addition, in limited circumstances, the Compensation Committee may exercise its discretion to pay other cash bonuses. Total compensation is targeted at or above the

median for the industry, depending on the executive’s experience, historical performance, and demands of the position. Total compensation increases with position and responsibility. Pursuant to our objective of aligning our executives’ interests with the interests of our equity holders, we create compensation packages that meet or exceed general industry levels by combining base salaries that are at or below industry levels with bonuses and equity incentives that are at or above industry levels. The percentage of compensation that is “at risk” also increases with position and responsibility. “At risk” compensation includes potential quarterly payouts under our non-equity incentive compensation plan and long-term incentive awards. Executives with greater roles in, and responsibility for, achieving our performance goals bear a greater proportion of the risk that those goals are not achieved and receive a greater proportion of the rewards if goals are met or surpassed.

Base Salary. We provide our executives with a base salary to provide them with an immediate financial incentive. Base salaries are determined based on (1) a review of salary ranges for similar positions at companies of similar size based on annual revenues, (2) the specific experience level of the executive, and (3) expected contributions by the executive. Base salaries are generally at or below our peer companies. Base salaries are approved by the Board’s Compensation Committee and are based on the recommendation of our CEO, Mr. Caruso. Base salaries are reviewed and adjusted from time to time based on individual merit, promotions, or other changes in job responsibilities. There are no automatic increases in base salary.

Our co-founder, Mr. Caruso, currently receives a minimal base salary. In lieu of receiving a market-based salary, Mr. Caruso elected to receive substantially all of his compensation in the form of equity awards.

Non-Equity Incentive Compensation Plan. Consistent with our compensation objectives described above, we also have a quarterly non-equity incentive compensation plan in which most of our salaried employees, including our executives, participate. Similar to base salaries, this plan provides our executives with potential cash payments which act as an incentive for current performance, while also encouraging behavior that is consistent with our long-term goals. In support of our compensation objectives, target payout amounts under this plan are generally above what management estimates to be the industry median, so that when combined with below or at median salaries, they create total cash compensation at or above the median of our industry generally.

We make these non-equity incentive compensation plan payments to participating executives if quarterly financial targets (generally a modified calculation of adjusted EBITDA) and certain business unit objectives are met. The financial targets and business unit objectives are proposed by the CEO (who does not participate in the non-equity incentive compensation plan) and are approved by the Compensation Committee. Our CEO recommends to the Compensation Committee the quarterly payouts under this plan, from 0% to 200% of an individual or a group’s target payout, based on the relative achievement of the financial targets and business unit objectives. The actual financial results may be adjusted up or down to account for certain non-recurring or unusual events, if approved by the Compensation Committee.

The business unit objectives that were set in Fiscal 2011 consisted of financial performance objectives, strategy initiatives, executive initiatives, and financial management goals, at the business unit level. The business unit objectives established for the company reflect a mix of near-term projects and longer-term improvement initiatives. Actual payouts under the plan are determined based on our CEO’s quantitative and qualitative evaluation of performance against the objectives and are approved by our Compensation Committee.

The table below shows the total target payouts and actual payouts under the non-equity incentive compensation plan for Fiscal 2011 for our Chief Executive Officer, Chief Financial Officer, and three most highly compensated other executive officers. We refer to these five people as our named executive officers.

Upon reevaluating the current ratio of base salary, bonus, and equity of our named executives, we may increase their bonus targets in connection with any increase in their base salaries with the approval of the Compensation Committee.

Our CEO, Mr. Caruso, does not earn a quarterly payment under the non-equity incentive compensation plan.

Equity. A significant percentage of total compensation for our executives is allocated to equity compensation. We believe equity ownership encourages executives to behave like owners and provides a clear link between the interest of executives and those of equity holders.

Certain employees, including our executives, are granted common units in CII, our indirect parent company. Upon a distribution at CII, the holders of common units are entitled to share in the proceeds of a distribution after certain obligations to the preferred unit holders are met. See Note 13: Equity of our audited consolidated financial statements included elsewhere in this prospectus for additional information on member’s equity of CII, including the common units.

Certain executives also received preferred units in CII. The preferred unit holders are not entitled to receive dividends or distributions (although CII may elect to include holders of preferred units in distributions at its discretion). Upon a distribution at CII the holders of preferred units are entitled to receive their unreturned capital contributions and a priority return of 6% prior to any distributions being made to common unit holders. After the unreturned capital contributions and priority returns are satisfied, preferred unit holders receive 80-85% of the proceeds of a distribution while the common unit holders receive the remaining 15-20%, depending on the aggregate preferred investor return on their investments.

Common units are awarded to executives upon hiring and at any time thereafter at the discretion of the Compensation Committee based on the executives’ past or expected role in increasing our equity value. All of the granted common units are subject to the terms of employee equity agreements covering vesting and transfer, among other terms.

In Fiscal 2011, each of the named executive officers received incremental grants based on the Compensation Committee’s subjective evaluation of their overall performance and expected contribution to the future increase in CII’s overall equity value.

Bonus. Under the terms of his offer letter, Mr. Howson was entitled to a signing bonus equal to $60,000, which was paid during Fiscal 2011.

Benefits. We offer our executives the same health and welfare benefit and disability plans that we offer to all of our employees.

Our CEO, Mr. Caruso, makes recommendations to the Compensation Committee regarding the total compensation of each executive (excluding himself), including base salary, target bonus, and equity compensation, as well as the financial targets and business unit objectives which determine bonus payouts. The Compensation Committee considers the CEO’s recommendations in consultation with the full Board, and makes all final decisions for the total amount of compensation and each element of compensation for our executives, including Mr. Caruso.

Mr. Caruso and the Compensation Committee use their general knowledge of the compensation practices of other similar telecommunications companies and other private equity-owned companies in the formulation of their recommendations and decisions. The day-to-day design and administration of savings, health, welfare and paid time-off plans and policies applicable to our employees in general, including our executives, are handled by company management and our professional employee organization, ADP.

During Fiscal 2011, our named executives have been granted the following preferred and common units in CII as equity compensation for services rendered.

Accelerated Vesting. Under the respective Employee Equity Agreements for Messrs. desGarennes, Russo, Snella and Howson, each of their unvested Units will immediately vest five months after the consummation of a sale of CII, provided that the relevant employee has remained continuously employed from the date of the relevant Employee Equity Agreement through the date of such sale and does not voluntarily terminate his employment prior to the expiration of such five months, if (i) all of the consideration paid in respect of such sale consists of cash or certain marketable securities or (ii) in the event that the consideration consists of other than cash or such securities, the board of directors of CII determines that such sale constituted a management control acquisition. For purposes of such Employee Equity Agreement, a “sale” of CII means any of (a) a merger or consolidation of CII or its subsidiaries into or with any other person or persons, or a transfer of units in a single transaction or a series of transactions, in which in any case the members of CII or the members of its subsidiaries immediately prior to such merger, consolidation, sale, exchange, conveyance or other disposition or first of such series of transactions possess less than a majority of the voting power of CII’s or its subsidiaries’ or any successor entity’s issued and outstanding capital securities immediately after such transaction or series of such transactions; or (b) a single transaction or series of transactions, pursuant to which a person or persons who are not direct or indirect wholly-owned subsidiaries of CII acquire all or substantially all of CII’s or its subsidiaries’ assets determined on a consolidated basis, in each case, other than (i) the issuance of additional capital securities in a public offering or private offering for the account of CII or (ii) a foreclosure or similar transfer of equity occurring in connection with a creditor exercising remedies upon the default of any indebtedness of CII. Further, for purposes of such Employee Equity Agreement, “management control acquisition” is defined as a sale of CII with respect to which (i) immediately prior to such sale of CII, Dan Caruso is serving CII as chief executive officer and (ii) after giving effect to the consummation of the sale of CII, Dan Caruso is not offered the opportunity to serve as the chief executive officer of the combined company resulting from such sale of CII.

Under the Vesting Agreements for Mr. Caruso, the unvested Preferred Units and Common Units will, upon a sale of CII, immediately vest, provided that the executive remains employed by CII or one of its subsidiaries. For purposes of the Vesting Agreements, “sale” of CII means any of the following: (a) a merger or consolidation of CII or its subsidiaries into or with any other person or persons, or a transfer of units in a single transaction or a series of transactions, in which in any case the members of CII or the members of its subsidiaries immediately prior to such merger, consolidation, sale, exchange, conveyance or other disposition or first of such series of transactions possess less than a majority of the voting power of CII’s or its subsidiaries’ or any successor entity’s issued and outstanding capital securities immediately after such transaction or series of such transactions; or (b) a single transaction or series of transactions, pursuant to which a person or persons who are not direct or indirect wholly-owned subsidiaries of CII acquire all or substantially all of CII’s or its subsidiaries’ assets determined on a consolidated basis, in each case whether pursuant to a sale, lease, transfer, exclusive license or other disposition outside of the ordinary course of business.

The following summary compensation table sets forth information concerning the annual and long-term compensation earned by our named executive officers.

The following table provides information about grants of plan based awards to our named executive officers in Fiscal 2011 and non-equity incentive plan award information for Fiscal 2011:

The table below lists the number and value of equity awards that have not vested at year end of Fiscal 2011:

We do not maintain a defined benefit pension plan, and there were no pension benefits earned by our executives in the year ended June 30, 2011.

Nonqualified Defined Contribution and Other Nonqualified Deferred Compensation Plans

We do not have any nonqualified defined contribution or other nonqualified deferred compensation plans covering our executives.

As a general practice the executives are not entitled to any payments upon termination or change-in-control other than those rights provided in the employee equity agreements. See “—Employment and Equity Arrangements” above for information regarding vesting of equity in CII upon a change of control of CII. The following table sets forth information about the market value of unvested units held by each of the named executives which would have accelerated upon a change in control on the last day of Fiscal Year 2011:

Prior to June 18, 2010, our Board was comprised of our Chief Executive Officer and representatives from a subset of our private equity investors. Neither our employee director nor the director representatives from our private equity investors received any compensation for their services on either the Board or Committees of the Board during Fiscal 2010. On June 18, 2010 we expanded our Board to include two independent directors not affiliated with our current investor base. Upon the expansion of the Board, we instituted a compensation program for independent directors. The following table details the compensation paid to non-employee directors during Fiscal 2011:

The independent board member compensation plan consists of an annual retainer of $25,000 for each independent director for their Board membership and separate annual fees for committee chairmanship and membership. These separate fees for independent directors are comprised of an annual fee of $12,500 for the chairmanship of the audit committee and $5,000 for the chairmanship of the compensation committee. In addition, each independent director who is a member, other than the chairman, of the audit committee receives an annual fee of $5,000 and an independent director who is a member, other than the chairman, of the compensation committee receives an annual fee of $2,500. Independent board members also receive a per-meeting fee of $1,000 for attendance at in-person Board meetings.

During Fiscal 2011, Mr. Connor was granted 63,739 Class D Common Units of which 33.3% will vest on January 1, 2012 and the remainder will vest pro rata on a monthly basis over the two-year period ending on January 1, 2014. The grant date fair value of Mr. Connor’s Class D Common Units was $0. Mr. Connor was also granted 50,000 Class E Common Units of which 33.3% will vest on May 20, 2012, and the remainder will vest pro rata on a monthly basis over the two-year period ending on May 20, 2014. The grant date fair value of Mr. Connor’s Class E Common Units was $11,500. We have also agreed to pay each independent director an amount sufficient to reimburse them for 50% of the applicable income taxes on the Class B Preferred Units granted to them in Fiscal 2010. Pursuant to the compensation program for independent directors, during Fiscal 2011, Mr. Connor received $97,524, including $55,524 to cover an estimate of the taxes assessed against the Class B preferred units granted to Mr. Connor during Fiscal 2010.

We reimburse our non-employee directors for travel, lodging and other reasonable out-of-pocket expenses in connection with the attendance at Board and committee meetings. We also provide liability insurance for our directors and officers.

On March 24, 2011, Don Detampel resigned from our Board of Directors. Mr. Detampel’s voluntary resignation was a result of his pursuit of alternative endeavors which could result in constraints on his time and potential business conflicts. There were no disagreements between Mr. Detampel and the Company or any officer or director of the Company which led to Mr. Detampel’s resignation. Mr. Detampel acted as one of our first two independent directors and served on our Board of Directors since July 2, 2010. With the resignation, Mr. Detampel also resigned from his role as Chairman of the Company’s Compensation Committee and as a member of the Audit Committee. In connection with his resignation, Mr. Detampel forfeited on all of his unvested equity grants which included 63,926 Class B Preferred Units, 110,935 Class C Common Units, and 55,572 Class D Common Units. During Fiscal 2011, pursuant to the compensation program for independent directors, Mr. Detampel received $85,584, including $48,583 to cover an estimate of the taxes assessed against Mr. Detampel’s Class B preferred unit grant.

Daniel Caruso is a founder of the Zayo Group and owns a substantial amount of equity of CII, our indirect parent company. Mr. Caruso currently acts as our Chief Executive Officer, but has not entered into an employment agreement with us or any entity affiliated with us that contractually determines his rights and obligations. On May 22, 2007, however, Mr. Caruso entered into a Founder Noncompetition Agreement with CII and on December 31, 2007, he entered into a Vesting Agreement with regard to certain equity in CII. In connection with the Sponsor Equity Contribution, Mr. Caruso’s non-competition agreement was extended to July 2, 2017. Pursuant to the noncompetition agreement, Mr. Caruso is, during the term of the agreement, not permitted to own, manage, work for, provide assistance to or be connected in any other manner with a business engaged in owning or operating fiber networks, other than with respect to us, subject to limited exceptions, including those noted below.

Mr. Caruso is an investor in Envysion, Inc. and GTS Central Europe and currently serves as the executive Chairman of Envysion, Inc. Envysion, Inc. is engaged in managed video as a service and is not a direct competitor of the Zayo Group.

Mr. Caruso, despite the fact that he does not have an employment agreement with Zayo Group, LLC or any of its affiliates, intends to devote the vast majority of his business time to Zayo Group, LLC and its subsidiaries.

In June 2012, CII and its preferred unit holders authorized a $7.0 million non-liquidating distribution against Zayo Group’s stock-based compensation liability to Mr. Caruso.

During Fiscal 2011, none of the members of the Compensation Committee served, or has at any time served, as an officer or employee of the Company or any of our subsidiaries. In addition, none of our executive officers has served as a member of a compensation committee, or other committee serving an equivalent function of any other entity.

SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT AND RELATED STOCKHOLDER MATTERS

One hundred percent of our equity is owned, indirectly, by CII. The following table sets forth the beneficial ownership of our indirect parent company, CII, by each person or entity that is known to us to own more than 5% of CII’s outstanding membership interests and each of our named executive officers and directors who owns an interest in CII as of July 10, 2012. CII’s membership interests are comprised of Preferred Class C Units and Common Units. The ownership rights of the members of CII are governed by the Third Amended and Restated Limited Liability Company Agreement, dated July 2, 2012.

On July 2, 2012, in connection with the Company’s acquisition of AboveNet, the Company completed a third round of equity financing in which 98,916,060.11 Class C Preferred Units were sold to new and existing investors for aggregate proceeds of $472.25 million. At the same time, all existing Preferred Units were converted into 257,548,148.92 Class C Preferred Units.

The Common Units do not carry voting rights. Upon a liquidation of the Company, the holders of the preferred units are entitled to receive their unreturned capital contributions and a priority return of 6% prior to any distributions being made to common unit holders. After the unreturned capital contributions and priority returns are satisfied, preferred unit holders receive 80% to 85% of the proceeds of a distribution while the common unit holders receive the remaining 15% to 20%, depending on the aggregate preferred investor return on investment. As of July 10, 2012, CII had 356,548,148.92 Preferred Class C Units outstanding and 175,168,378 common units outstanding. Beneficial ownership is determined in accordance with the rules of the SEC. Except as otherwise indicated, to our knowledge, the persons named in the table below have sole voting and investment power with respect to all units shown as owned by them except as otherwise set forth in the notes to the table and subject to community property laws, where applicable.

We acquired Onvoy on November 7, 2007 at which time Onvoy operated as a vertically integrated telecommunications company. Subsequent to our acquisition of Onvoy, we separated the business of Onvoy into three distinct operating business units. Two of the business units of Onvoy were integrated into our Zayo Bandwidth and Zayo Enterprise Networks business units following the acquisition. The third business unit, Onvoy Voice Services, remained with Onvoy.

During the third quarter of 2010, management determined that the services provided by Onvoy did not fit within the Company’s current business model of providing telecom and internet infrastructure services, and the Company therefore spun off Onvoy to Holdings, the parent of the Company.

On April 1, 2011, after completing a restructuring of our operating segments, we determined that the ZEN unit no longer fit within our current business model and we spun the ZEN unit to our ultimate parent, CII. CII subsequently contributed the assets and liabilities of ZEN to its Onvoy subsidiary.

We have certain ongoing contractual relationships with Onvoy, which are based on agreements entered into at market rates between Onvoy and us.

The contractual relationships between us and Onvoy cover the following services:

We have entered into a Master Services Agreement with Onvoy which requires us to provide the following services to Onvoy:

We have entered into a Master Services Agreement with Onvoy which requires Onvoy to provide the following services to us:

In addition to the services and contracts described above, we have entered into transition services agreements with Onvoy that outline each party’s responsibility with regards to payment to, and separation of services associated with, shared vendors. Furthermore, we have entered into a management agreement with

Onvoy which relates to certain services provided for Onvoy by our management, such as compensation and benefits, insurance, tax, financial services and other corporate support.

Subsequent to the April 1, 2011 spin-off of ZEN and the March 12, 2010 spin-off of Onvoy, the revenue and expenses associated with transactions with ZEN and Onvoy have been recorded in the results from continuing operations. The following table represents the revenue and expense transactions recognized with these related parties subsequent to their spin-off dates:

We, or Onvoy, may terminate existing contracts in the future or we may enter into additional or other contractual arrangements with Onvoy as a result of which our contractual relationship with Onvoy and the payments among us and Onvoy pursuant to such contracts may substantially change.

As of June 30, 2011, the Company had a receivable balance due from Onvoy, in the amount of $187.0 million related to services the Company provided to OVS and/or ZEN.

On September 14, 2010, Dan Caruso, our President, Chief Executive Officer and Director, purchased $500,000 (face amount) of our Existing Notes in connection with our September 20, 2010 $100.0 million Existing Notes offering. The purchase price of the Existing Notes purchased by Mr. Caruso was $516,000, including the premium on the Existing Notes and accrued interest.

On June 28, 2012, Matthew Erickson, the President of ZFS, purchased $600,000 in aggregate principal amount of our 10.125% senior unsecured notes due 2020 at the offering price for such notes in the Private Notes Offering. Mr. Erickson qualifies as an “accredited investor” (as defined in Rule 501 under the Securities Act), and this purchase was on terms available to other investors.

As of March 31, 2012 and June 30, 2011, the Company had a due to related-party balance with CII of $15.5 million and $4.6 million, respectively, which is payable on demand. During the nine months ended March 31, 2011, CII made an advance payment to the Company in the amount of $17.6 million of which $13.0 million was returned to CII during the same period. The advance was used to make an interest payment on the Company’s Existing Notes. The liability to CII as of March 31, 2012 relates to the net $4.6 million interest payment made by CII on the Company’s Existing Notes in March 2011 and $11.0 million in cash provided to the Company to fund the December 2011 acquisition of 360networks.

Our board of directors is comprised of a majority of non-independent directors. Although the Company’s equity is not publicly traded, the Company utilized the definition of director “independence” as defined in Rule 5605(a)(2) of the Marketplace Rules of the NASDAQ Stock Market. Rick Connor, our Audit Committee Chairman, is our only independent director. Our board of directors has an audit committee and compensation committee. Each member of the compensation committee is a non-employee director as defined in Rule 16b-3 of the Exchange Act and is an outside director as defined in Section 162(m) of the Internal Revenue Code.

The following is a summary of provisions relating to our material indebtedness other than the Notes.

Our obligations under the New Credit Facilities are guaranteed by our domestic subsidiaries, subject to certain exceptions. All obligations under the New Credit Facilities are secured by a lien and security interest on substantially all of our tangible and intangible assets and those of the subsidiary guarantors, subject to certain exceptions. This lien is equally and ratably shared with the lien securing our obligations and those of such subsidiaries in respect of the Secured Notes. Until such time as the requisite regulatory approvals have been obtained from certain state public utility commissions, borrowings under the New Revolving Credit Facility shall not exceed $130,000,000.

Borrowings under the New Term Loan Facility bear interest per annum at a fixed rate, at our option subject to certain restrictions, of LIBOR plus a margin of 5.875%, or the Base Rate plus a margin of 4.875%. At the closing date, borrowings under the New Revolving Credit Facility accrued interest per annum at a fixed rate, at our option subject to certain restrictions, of LIBOR plus a margin of 5.375%, or the Base Rate plus a margin 4.375%. The margins for revolving loans are subject to quarterly adjustment commencing at the first full fiscal quarter after the closing date based on our leverage ratio. The “Base Rate” is equal to the greater of (i) the Federal Funds effective rate plus 50 basis points and (ii) LIBOR for a one-month interest period (calculated daily) plus 100 basis points; in no case will the Base Rate applicable to the New Term Loan Facility be less than 2.25% per annum and in no case will LIBOR applicable to the New Term Loan Facility be less than 1.25% per annum. Borrowings under the New Credit Facilities are prepayable at any time prior to maturity (subject to advance notice) without penalty, other than customary breakage costs and redeployment costs.

On June 4, 2012, we commenced a cash tender offer and consent solicitation for any and all of our $350 million outstanding 10.25% senior secured first-priority notes due 2017. On July 2, 2012, we announced that we had accepted for purchase $347 million or 99% of the outstanding Existing Notes that were tendered at the expiration of the Tender Offer. In connection with the Tender Offer, we also received the requisite consents to approve the amendments to the indenture governing the Existing Notes that eliminated most of the restrictive covenants and certain of the events of default and released the collateral securing the obligations under the Existing Notes. Also on July 2, 2012, we announced that we would redeem the remaining $3 million of outstanding Existing Notes on August 1, 2012 pursuant to a Notice of Full Redemption issued on July 2, 2012.

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

The Secured Exchange Notes will be issued under an indenture, dated as of June 28, 2012, between Escrow Corp and The Bank of New York Mellon Trust Company N.A., as trustee (the “Trustee”), as supplemented by the First Supplemental Indenture thereto, dated as of July 2, 2012, among the Issuers, Escrow Corp, the guarantors party thereto and the Trustee (the “Secured Indenture”). The terms of the Secured Notes include those set forth in the Secured Indenture and those made part of the Secured Indenture by reference to the Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”).

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

Any Secured Outstanding Notes that remain outstanding after the completion of the exchange offer, together with the Secured Exchange Notes issued in connection with the exchange offer, will be treated as a single class of notes under the Secured Indenture. As a result, we refer to the Secured Exchange Notes and the Secured Outstanding Notes collectively as the “Secured Notes” for purposes of the following summary.

The following description is a summary of the material terms of the Secured Indenture and the Security Documents. It does not, however, restate the Secured Indenture or any Security Document in their entirety. You should read the Secured Indenture and the Security Documents because they contain additional information and because they and not this description define your rights as a holder of the Secured Notes. Copies of the Secured Indenture and the Security Documents may be obtained by requesting them from the Company.

The following summary also includes a description of certain actions to be taken by certain Grantors to grant (and, where applicable, register or perfect) initial security interests in their assets after the closing of the initial offering of the Secured Outstanding Notes. Such Grantors have completed all such actions required under the Secured Indenture through the date of this prospectus.

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

As of March 31, 2012, on an as adjusted basis after giving effect to the issuance of the Secured Notes and the Unsecured Notes, the use of proceeds thereof, and the entry into the New Credit Facilities, and after excluding intercompany balances and intercompany guarantees:

As of the date of this prospectus, all of the Company’s Domestic Subsidiaries (other than Zayo Capital, Inc., the co-issuer) are Guarantors and guarantee the Secured Notes. However, the Secured Indenture does not require any future Foreign Subsidiaries to provide a Secured Note Guarantee unless such Foreign Subsidiary guarantees other Indebtedness of the Issuers. Certain Subsidiaries acquired in the AboveNet Acquisition are Foreign Subsidiaries of the Company. Accordingly, they and any other future Foreign Subsidiaries of the Company may not be Guarantors. 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 Domestic 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 Secured Indenture. Further, Unrestricted Subsidiaries will not Guarantee the Secured Notes.

Although the Secured 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 Secured Notes will mature on January 1, 2020. The Issuers will issue up to $750 million aggregate principal amount of Secured Notes in the exchange offer. Subject to the covenant described under “—Certain Covenants—Limitation on Indebtedness,” the Issuers are permitted to issue additional Secured Notes under the Secured Indenture (“Additional Secured Notes”). The Secured Notes and any Additional Secured Notes that are issued will be treated as a single class under the Secured Indenture, including with respect to waivers, amendments, redemptions and Offers to Purchase. The Additional Secured Notes will be secured, subject to Permitted Liens, on a first-priority basis equally and ratably with the Secured Notes and any other Permitted Additional Pari Passu Obligations. The Additional Secured Notes may be issued at different prices from the original issue price of the Secured Notes. Unless the context otherwise requires, references to the “Secured Notes” for all purposes under the Secured Indenture and in this “Description of the Senior Secured First-Priority Notes” include any Additional Secured Notes that are issued.

Interest on the Secured 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 8.125%, and will be payable semi annually in arrears on January 1 and July 1 of each year, commencing on January 1, 2013. Interest will be payable to Holders of record on each Secured Note in respect of the principal amount thereof outstanding as of the immediately preceding December 15 or June 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 Secured Notes. In no event will the rate of interest on the Secured Notes be higher than the maximum rate permitted by applicable law.

The Secured 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 Secured Notes will be initially in the form of one or more global notes (the “Global Notes”). The Global Notes will be deposited with the Trustee as custodian for the Depository Trust Company (“DTC”). Ownership of interests in the 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 Secured Indenture will provide for the issuance of definitive registered Secured Notes in certain circumstances. Please see the section entitled “—Book Entry, Delivery and Form.”

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

A Holder may transfer or exchange Secured Notes in accordance with the Secured 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 Secured 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 Secured Note selected for redemption. Also, the Issuers are not required to transfer or exchange any Secured Note for a period of 15 days before a selection of Secured 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 Secured Notes in accordance with those instructions. All other payments on Secured 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 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 Secured Notes, the Secured Note Guarantees, and all other Pari Passu Obligations will be secured equally and ratably by continuing first priority security interests (subject to Permitted Liens and certain exceptions) in substantially all of the tangible and intangible assets of the Issuers and the Guarantors, whether now owned or hereafter acquired or arising, and wherever located, including, but not limited to, all existing and future Capital Stock and intercompany debt of any Domestic Subsidiary owned directly by the Issuers or any Guarantor and all existing and future Capital Stock of any Foreign Subsidiary owned directly by the Issuers or any Guarantor (limited (i) in the case of any such Foreign Subsidiaries, to 65% of the Capital Stock of such Foreign Subsidiaries, and (ii) in the case of all Subsidiaries of the Company, to the maximum amount which would not require the filing with the SEC of separate financial statements for such Subsidiary pursuant to Rule 3-16 of Regulation S-X under the Securities Act), accounts receivable, deposit accounts, chattel paper, inventory, equipment, leasehold interests, investment property, intellectual property, interests in commercial tort claims, other general intangibles and certain real property, and all proceeds of the foregoing, subject to the exceptions discussed in the succeeding paragraph (collectively, the “Collateral”).

The Collateral will exclude certain items of property, including without limitation:

No grants of mortgages or other perfection steps taken with respect to Real Property have occurred as of the date of this prospectus, because none of the Real Property interests of the Issuers or the Guarantors meets the aforementioned $5,000,000 threshold. Such unmortgaged Real Property interests include, without limitation, numerous leases of real property, some of which are material to the present conduct of the business of the Issuers and the Guarantors and as to which the Issuers and the Guarantors will use commercially reasonable efforts to obtain landlord waivers or collateral access waivers.

On the date of the Assumption, the Issuers and the Initial Guarantors entered into the Security Documents (including, without limitation, the Security Agreement and the Intercreditor Agreement) with the Collateral Agent, which documents provide for the grant of security interests in the Collateral in favor of the Collateral Agent, for the benefit of the Trustee and the Holders of the Secured Notes and the New Credit Facility Lenders under the New Credit Facilities; provided that the Issuers and the Guarantors, as applicable, may use their commercially reasonable efforts to execute and deliver certain deposit account control agreements and certain other ancillary Security Documents required to cause the Secured Notes to be secured by Liens on the Collateral after the Issue Date with the approval of, and within the time frame agreed to by, the collateral agent for the lenders under the New Credit Facilities.

The Issuers will, and the Company will cause each of the Guarantors to, do or cause to be done all acts and things which may be required, or which the Collateral Agent from time to time may reasonably request, to assure and confirm that the Collateral Agent holds, for the benefit of the Trustee and the Holders of the Secured Notes and the New Credit Facility Lenders, duly created, enforceable and perfected Liens upon the Collateral as contemplated by the Secured Indenture and the Security Documents.

The Issuers and the Guarantors will be able to Incur additional Indebtedness in the future which could share in the Collateral. Any such Indebtedness may limit the recovery from the realization of the value of such Collateral available to satisfy the Holders of the Secured Notes and the New Credit Facility Lenders. The lenders with respect to such Indebtedness will be required to join the Intercreditor Agreement as Additional Pari Passu Secured Parties. No Collateral will secure any other Indebtedness unless such Collateral also secures the Secured Notes Obligations and the New Credit Facility Obligations. The amount of all such additional Indebtedness will be limited by the covenants disclosed under “—Certain Covenants—Limitation on Indebtedness” and “—Certain Covenants—Limitation on Liens.” Under certain circumstances the amount of such additional Indebtedness could be significant.

No appraisals of any Collateral have been prepared in connection with this offering. The value of the Collateral at any time is subject to fluctuation based on factors that include, among others, the condition of the telecommunications industry, the ability to sell the Collateral in an orderly sale, general economic conditions, the availability of suitable buyers and similar factors. By their nature, some or all of the Collateral may be illiquid and may have no readily ascertainable market value. We cannot assure you that the fair market value of the Collateral as of the date of this prospectus exceeds the principal amount of the Indebtedness secured thereby. The value of the assets pledged as Collateral for obligations under the Secured Indenture and the New Credit Facilities could be impaired in the future as a result of changing economic conditions, our failure to implement our business strategy, competition or other future trends.

We cannot assure you that, in the event of a foreclosure, the proceeds from the sale of the portion of the Collateral allocated or allocable to the repayment of the obligations under the Secured Indenture and the New Credit Facilities would be sufficient to satisfy the amounts outstanding under the Secured Notes and the loans under the New Credit Facilities. If such proceeds were not sufficient to repay amounts outstanding under the Secured Notes and the loans under the New Credit Facilities, the holders of the Secured Notes and the lenders under the New Credit Facilities (to the extent not repaid from the proceeds of the sale of the Collateral) would have only an unsecured, general claim against us and our Guarantors’ remaining assets, which claim would rank equal in priority to unsecured general Indebtedness. In the event that a bankruptcy case is commenced by or against us, if the value of the Collateral is less than the amount of principal and accrued and unpaid interest on the Secured Notes and all other secured obligations, interest may cease to accrue on the Secured Notes from and after the date the bankruptcy petition is filed.

Promptly following the acquisition by the Issuers or any Guarantor of any After-Acquired Property (but subject to the applicable limitations in the Security Documents), the Issuers or such Guarantor will execute and deliver such security agreement supplements, mortgages, deeds of trust, security instruments, financing statements, title insurance, surveys and certificates and opinions of counsel as are reasonably necessary to vest in the Collateral Agent a perfected security interest or other Liens in or on such After-Acquired Property and to have such After-Acquired Property added to the Collateral, and thereupon all provisions of the Secured Indenture relating to the Collateral will be deemed to relate to such After-Acquired Property to the same extent and with the same force and effect.

On the date of the Assumption, the Issuers, the Guarantors, the Trustee (as Authorized Representative for the Holders of the Secured Notes), Morgan Stanley Senior Funding, Inc. (in its capacity as Authorized Representative for the New Credit Facility Lenders and administrative agent for the New Term Loan Facility, the “New Credit Facility Agent”), SunTrust Bank (in its capacity as administrative agent for the New Revolving Credit Facility) and the Collateral Agent entered into a Collateral Agency and Intercreditor Agreement (as the same may be amended from time to time, the “Intercreditor Agreement”), with respect to the Collateral, which Intercreditor Agreement may be amended from time to time without the consent of the Holders of the Secured Notes to add additional lenders holding Additional Pari Passu Obligations permitted to be incurred under the Secured Indenture, the New Credit Facilities, the Intercreditor Agreement and any Additional Pari Passu Agreements then in effect.

By accepting the Secured Notes, each Holder will be deemed to have irrevocably appointed, as of the date of the Assumption, SunTrust Bank as the Collateral Agent, to act as its agent under the Intercreditor Agreement, the Security Agreement and the other Security Documents, and to have irrevocably authorized the Collateral Agent to perform the duties and exercise the rights powers and discretions that are specifically given to it under the Intercreditor Agreement, the Security Agreement and the other Security Documents, together with any other incidental rights power and discretion. Under the terms of the Intercreditor Agreement, the Collateral Agent may resign on 30 days prior written notice, and the Collateral Agent may also be removed for cause and replaced by a replacement collateral agent selected by the Applicable Authorized Representative, in consultation with the Issuers.

The Collateral Agent will hold (directly or through co trustees, co-agents, agents or sub agents), and will be entitled to enforce, all Liens on the Collateral created by the Security Documents. The Collateral Agent will, at least initially, be the same institution that will be serving as the administrative agent for the revolving credit facility under the New Credit Facilities.

Under the Intercreditor Agreement, the Applicable Authorized Representative has the right, under certain circumstances, to direct the Collateral Agent to foreclose or take other actions with respect to the Collateral, and no other party to the Intercreditor Agreement will have the right to take any action with respect to the Collateral. Except as described below, the Applicable Authorized Representative will be the Authorized Representative of the Series of Pari Passu Obligations that constitutes the largest outstanding principal amount of any then-outstanding Series of Pari Passu Obligations (the “Controlling Authorized Representative”). Upon the occurrence of the Non-Controlling Authorized Representative Enforcement Date (as defined below), the then-Applicable Authorized Representative will be replaced as Applicable Authorized Representative by the Authorized Representative of the Series of Pari Passu Obligations that then constitutes the next largest outstanding principal amount of any then outstanding Series of Pari Passu Obligations with respect to the Collateral (the “Major Non-Controlling Authorized Representative”).

The “Non-Controlling Authorized Representative Enforcement Date,” with respect to which a Major Non-Controlling Authorized Representative becomes the Applicable Authorized Representative is the date that is 90 days (throughout which 90-day period the applicable Non-Controlling Authorized Representative was the Major Non-Controlling Authorized Representative) after the occurrence of both (a) an event of default, as defined in the Secured Indenture, the New Credit Facilities or any other applicable indenture or credit document for that Series of Pari Passu Obligations, and (b) the Collateral Agent’s and each other Authorized Representative’s receipt of written notice from that Authorized Representative certifying that (i) such Authorized Representative is the Major Non-Controlling Authorized Representative and that an event of default, as defined in the Secured Indenture, the New Credit Facilities or any other applicable indenture or credit document for that Series of Pari Passu Obligations, has occurred and is continuing and (ii) the Pari Passu Obligations of that Series are currently due and payable in full (whether as a result of acceleration thereof or otherwise) in accordance with the Secured Indenture, the New Credit Facilities or other applicable indenture or credit document, as applicable, for that Series of Pari Passu Obligations; provided that the Non-Controlling Authorized Representative Enforcement Date will be stayed and shall not occur and shall be deemed not to have occurred with respect to any Collateral if (1) at any time the Collateral Agent has commenced and is diligently pursuing any enforcement action with respect to such Collateral or (2) at any time the Issuers or the Guarantor that has granted a security interest in such Collateral is then a debtor under or with respect to (or otherwise subject to) any insolvency or liquidation proceeding. If no such stay occurs, or is deemed to occur, then the Major Non-Controlling Authorized Representative will become the Applicable Authorized Representative from and after the occurrence of the Non-Controlling Authorized Representative Enforcement Date. As of the date of this prospectus, Morgan Stanley Senior Funding, Inc., in its capacity as Authorized Representative for the New Credit Facility Lenders under the New Credit Facilities, is the Controlling Authorized Representative and the Applicable Authorized Representative, and the Trustee, in its capacity as Authorized Representative for the Holders of the Secured Notes, is the initial Major Non-Controlling Authorized Representative.

The Applicable Authorized Representative will have the sole right to instruct the Collateral Agent to act or refrain from acting with respect to the Collateral, and (a) the Collateral Agent will not follow any instructions (other than certain types of instructions to exercise rights other than enforcement rights) with respect to the Collateral from any representative of any Non-Controlling Secured Party or other Pari Passu Secured Party (other than the Applicable Authorized Representative), and (b) no Authorized Representative of any Non-Controlling Secured Party or other Pari Passu Secured Party (other than the Applicable Authorized Representative) will instruct the Collateral Agent to commence any judicial or non-judicial foreclosure proceedings with respect to, seek to have a trustee, receiver, liquidator or similar official appointed for or over, attempt any action to take possession of, exercise any right, remedy or power with respect to, or otherwise take any action to enforce its interests in or realize upon, or take any other action available to it in respect of, the Collateral.

No representative of any Non-Controlling Secured Party may contest, protest or object to any foreclosure proceeding or action brought by or at the direction of the Collateral Agent in connection with the Intercreditor Agreement or the exercise of remedies against the Collateral. Each Authorized Representative has agreed that it will not accept any Lien on any Collateral for the benefit of any series of Pari Passu Obligations (other than funds deposited for the discharge or defeasance of any Additional Pari Passu Agreement) unless each other series of Pari Passu Obligations is also secured by a Lien on such Collateral. Each of the Pari Passu Secured Parties will also agree that it will not contest or support any other person in contesting, in any proceeding (including any insolvency or liquidation proceeding), the perfection, priority, validity or enforceability of a Lien held by or on behalf of any of the Pari Passu Secured Parties in all or any part of the Collateral, or the provisions of the Intercreditor Agreement.

If an Intercreditor Event of Default has occurred and is continuing and the Collateral Agent takes action to enforce rights in respect of any Collateral, or any distribution is made with respect to any Collateral in any bankruptcy case of the Issuers or any Guarantor, the proceeds of any sale, collection or other liquidation of any Collateral by the Collateral Agent or any other Pari Passu Secured Party (or received pursuant to any other intercreditor agreement), as applicable, the proceeds of any such distribution (subject, in the case of any such distribution, to the paragraph immediately following) shall be applied:

FIRST, to the payment of all reasonable legal fees and expenses and other reasonable costs or out-of-pocket expenses or other liabilities of any kind incurred by the Collateral Agent, acting on behalf of the Pari Passu Secured Parties under any Pari Passu Security Document or otherwise in connection with any Pari Passu Security Document or the Intercreditor Agreement;

SECOND, to the Collateral Agent and to any Authorized Representative, ratably in an amount equal to any fees, expenses (including any lawyers fees and expenses) and, with respect to any Authorized Representative, any indemnity amounts (including, in the case of any Authorized Representative, any fees and expenses owed to the Collateral Agent under the Intercreditor Agreement and any Pari Passu Security Document which has been advanced or paid to the Collateral Agent by such Authorized Representative) owed to such person under the Intercreditor Agreement and any Pari Passu Security Documents which are unpaid;

THIRD, to the payment in full of all other Pari Passu Obligations then due and owing on a ratable basis among all Series, to be applied in accordance with the terms of the applicable Secured Credit Documents; and

FOURTH, after payment in full of all Pari Passu Obligations, to the Company for the account of the Company or the applicable Guarantor as its interests may appear.

Notwithstanding the foregoing, with respect to any Collateral for which a third party (other than a Pari Passu Secured Party) has a lien or security interest that is junior in priority to the security interest of any Series of Pari Passu Obligations but senior (as determined by appropriate legal proceedings in the case of any dispute) to the security interest of any other Series of Pari Passu Obligations (such third party, an “Intervening Creditor”), the value of any Collateral or proceeds, of which are allocated to such Intervening Creditor will be deducted on a ratable basis solely from the Collateral or proceeds to be distributed in respect of the Series of Pari Passu Obligations with respect to which such impairment exists.

None of the Pari Passu Secured Parties may institute any suit or assert in any suit, bankruptcy, insolvency or other proceeding any claim against the Collateral Agent or any other Pari Passu Secured Party seeking damages from or other relief by way of specific performance, instructions or otherwise with respect to any Collateral. In addition, none of the Pari Passu Secured Parties may seek to have any Collateral or any part thereof marshaled upon any foreclosure or other disposition of such Collateral. If any Pari Passu Secured Party obtains possession of any Collateral or realizes any proceeds or payment in respect thereof, at any time prior to the discharge of each of the Pari Passu Obligations, then it must hold such Collateral, proceeds or payment in trust for the other Pari Passu Secured Parties and promptly transfer such Collateral, proceeds or payment to the Collateral Agent to be distributed in accordance with the Intercreditor Agreement.

The Pari Passu Secured Parties acknowledge that the Pari Passu Obligations may, subject to the limitations set forth in the other Secured Credit Documents, be increased, extended, renewed, replaced, restated, supplemented, restructured, repaid, refunded, refinanced or otherwise amended or modified from time to time, all without affecting the priorities set forth in the Intercreditor Agreement defining the relative rights of the Pari Passu Secured Parties; provided that the authorized representative of the holders of such amended or modified Indebtedness shall have executed a Joinder Agreement to the Intercreditor Agreement on behalf of the holders of such additional refinancing Indebtedness.

The Issuers and the Guarantors will be entitled to the release of property and other assets included in the Collateral from the Liens securing the Pari Passu Obligations under any one or more of the following circumstances:

The Liens on the Collateral securing the Secured Notes and the Guarantees will also be released upon (i) the termination and release of all Liens on Collateral in accordance with the terms of the Secured Indenture, the New Credit Facilities, each Additional Pari Passu Agreement then in effect, the Intercreditor Agreement, and all other applicable Pari Passu Security Documents, or (ii) the consent of each Authorized Representative, the Issuers and, as applicable, Holders of the Secured Notes and Lenders under the Credit Facility and the Guarantors, it being agreed that the release of the Collateral pursuant to the preceding clause (i) or (ii) will be concurrent with the termination of the Intercreditor Agreement and the other Pari Passu Security Documents (including the release of all Liens granted thereunder).

The Collateral Agent may enter into any amendment to any Pari Passu Security Document, so long as the Collateral Agent receives a certificate of the Company stating that such amendment is permitted by the terms of the Secured Indenture, the New Credit Facilities and each other Secured Credit Document then in effect. The Collateral Agent will give notice to each Authorized Representative of any release of Collateral and of any amendment to any Pari Passu Security Document.

The Collateral will be pledged pursuant to the Security Documents, which contain provisions relating to the administration of the Collateral. The following is a summary of some of the covenants and provisions set forth in the Security Documents and the Secured Indenture as they relate to the Collateral:

Further Assurances. The Security Documents and the Secured Indenture provide that each Grantor will, at its own expense, promptly execute and deliver all further instruments and documents, and take all further action, that may be necessary, or that Collateral Agent may request, in order to perfect any security interest granted or purported to be granted thereby or to enable the Collateral Agent to exercise and enforce its rights and remedies under such Security Documents with respect to any of the Collateral. Under the terms of the Security Agreement, each Grantor authorizes the filing by the Collateral Agent of financing or continuation statements, or amendments, and such Grantor will execute and deliver to the Collateral Agent such other instruments or notices, as may be necessary or as Collateral Agent may request, in order to perfect and preserve the security interest granted or purported to be granted under the Security Agreement.

Real Property Mortgages and Filings. Each Grantor agrees that upon the acquisition of any fee interest in Real Property in excess of $5,000,000 in value it will promptly notify the Collateral Agent of such acquisition and will grant to the Collateral Agent, for the benefit of the Pari Passu Secured Parties (including the Trustee and

the Holders of the Secured Notes), a first priority mortgage (subject to Permitted Liens) on each fee interest in Real Property owned by such Grantor and will deliver such other documentation and opinions, in form and substance satisfactory to Collateral Agent, in connection with the grant of such mortgage as the Collateral Agent reasonably requests, including title insurance policies, financing statements, fixture filings and environmental audits and such Grantor will pay all recording costs, intangible taxes and other fees and costs (including attorneys’ fees and expenses) incurred in connection therewith.

FCC Licenses and State PUC Licenses. The Collateral Agent’s rights with respect to the FCC Licenses and the State PUC Licenses, or assets subject thereto, are expressly subject to, and limited by any restrictions imposed by, the Communications Act and State Telecommunication Laws, as applicable. Prior to the exercise by Collateral Agent of any power, rights, privilege, or remedy under the Security Agreement which requires any consent, approval, or authorization of the FCC or any other governmental authority, the relevant Grantors will, at the Collateral Agent’s request, execute and deliver all applications, certificates, instruments, and other documents and papers that Collateral Agent determines may be required to obtain such consent, approval, or authorization. Neither the Collateral Agent nor any receiver appointed by reason of the exercise of any remedies will control, supervise, direct, or manage, or attempt to control, supervise, direct, or manage, the business of any Grantor, in any case that would result in any assignment of any FCC License or State PUC License or a transfer of control of any Grantor, any FCC License or any State PUC License, or assets subject thereto, if such assignment or such transfer of control would require under the Communications Laws or State Telecommunications Laws the prior approval of the FCC or any other governmental authority without first obtaining such approval.

New Subsidiaries. Pursuant to the Secured Indenture and the terms of the New Credit Facilities, on and after the date of the Assumption, any new direct Domestic Subsidiary (whether by acquisition or creation) of a Grantor is required to enter into the Security Agreement by executing and delivering a supplement to the Security Agreement in the form attached to the Security Agreement within 30 days following the acquisition or creation thereof. The ability of any future Domestic Subsidiary to enter into the Security Agreement may be subject to prior approval by certain State PUCs. Upon the execution and delivery of such supplement by such new Domestic Subsidiary, such Domestic Subsidiary shall become a Grantor under the Security Agreement, with the same force and effect as if originally named as a Grantor on the Issue Date. The execution and delivery of any instrument adding an additional Grantor as a party to the Security Agreement shall not require the consent of any then-existing Grantor.

The right of the Collateral Agent (acting on behalf of the Trustee and the Holders of the Secured Notes) to repossess and dispose of Collateral upon the occurrence of an Event of Default would be significantly impaired by applicable bankruptcy law in the event that a bankruptcy case were to be commenced by or against the Issuers or any Guarantor prior to the Collateral Agent’s having repossessed and disposed of the Collateral. Upon the commencement of a case for relief under Title 11 of the United States Bankruptcy Code of 1978, as amended (the “Bankruptcy Code”), a secured creditor such as the Collateral Agent (acting on behalf of the Pari Passu Secured Parties) is prohibited from repossessing its security from a debtor in a bankruptcy case, or from disposing of security repossessed from the debtor, without bankruptcy court approval.

In view of the broad equitable powers of a U.S. bankruptcy court, it is impossible to predict how long payments under the Secured Notes and the New Credit Facilities could be delayed following commencement of a bankruptcy case, whether or when the Collateral Agent could repossess or dispose of the Collateral, the value of the Collateral at the time of the bankruptcy petition or whether or to what extent Holders of the Secured Notes or the lenders under the New Credit Facilities would be compensated for any delay in payment or loss of value of the Collateral. The Bankruptcy Code permits only the payment and/or accrual of post petition interest, costs and attorneys’ fees to a secured creditor during a debtor’s bankruptcy case to the extent the value of the Collateral is determined by the bankruptcy court to exceed the aggregate outstanding principal amount of the obligations secured by the Collateral.

Furthermore, in the event a domestic or foreign bankruptcy court determines that the value of the Collateral is not sufficient to repay all amounts due on the Secured Notes, the Holders of the Secured Notes would hold secured claims to the extent of the value of the Collateral to which the Holders of the Secured Notes are entitled, and unsecured claims with respect to such shortfall.

The Secured Indenture provides that, to the extent applicable, the Company will comply with the provisions of the Trust Indenture Act Section 314(b) after qualification of the Secured Indenture pursuant to the Trust Indenture Act.

The Company will cause Section 313(b) of the Trust Indenture Act, relating to reports, and Section 314(d) of the Trust Indenture Act, relating to the release of property and to the substitution therefor of any property to be pledged as collateral for the Secured Notes, to be complied with, after qualification of the Secured Indenture under the Trust Indenture Act. Any certificate or opinion required by Section 314(d) of the Trust Indenture Act may be made by an Officer of the Company except in cases where Section 314(d) requires that such certificate or opinion be made by an independent engineer, appraiser or other expert, who shall be reasonably satisfactory to the Trustee. Notwithstanding anything to the contrary in this paragraph, the Company will not be required to comply with all or any portion of Section 314(d) of the Trust Indenture Act if they determine, in good faith based on advice of counsel, that under the terms of Section 314(d) and/or any interpretation or guidance as to the meaning thereof of the Commission and its staff, including “no action” letters or exemptive orders, all or any portion of Section 314(d) is inapplicable.

On the date of the Assumption and upon joining the Secured Indenture, the Initial Guarantors jointly and severally agreed to guarantee the due and punctual payment of all amounts payable under the Secured Notes, including principal, premium, if any, and interest. The Secured Indenture will require 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 Secured Note Guarantee. The ability of any future Domestic Subsidiaries to provide a Secured Note Guarantee may be subject to prior approval by certain State PUCs. See “—Certain Covenants—Future Subsidiary Secured Note Guarantees.”

Each Secured Note Guarantee of a Guarantor will be the Guarantor’s secured obligation, secured on a first priority basis, subject to Permitted Liens. The Secured Indenture states that each Guarantor under its Secured 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 Secured 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 Secured Notes and the Unsecured 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 Secured Note Guarantee will be entitled to contribution from any other Guarantor.

A Secured 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 Secured Indenture;

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

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

(4) upon a Legal Defeasance or satisfaction and discharge of the Secured 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 Secured Notes then outstanding and all other obligations under the Secured Indenture and the Secured Notes then due and owing.

Upon any occurrence giving rise to a release of a Secured Note Guarantee as specified above, the Trustee will, at the written direction of the Company, execute any documents reasonably required in order to evidence or effect such release, termination and discharge in respect of such Secured Note Guarantee. Neither the Issuers nor any Guarantor will be required to make a notation on the Secured Notes to reflect any Secured Note Guarantee or any such release, termination or discharge. Upon any release of a Guarantor from its Secured Note Guarantee, such Guarantor shall also be released from its obligations under the Security Documents.

At any time prior to July 1, 2015, the Issuers may redeem up to 35% of the aggregate principal amount of Secured Notes issued under the Secured Indenture (including any Additional Secured Notes) at a redemption price of 108.125% of the principal amount thereof, plus accrued and unpaid interest, if any, thereon to the redemption date, subject to the rights of Holders of Secured 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 65% of the aggregate principal amount of Secured Notes issued under the Secured Indenture (including any Additional Secured Notes) remains outstanding immediately after the occurrence of such redemption (excluding Secured 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 July 1, 2015, the Issuers may redeem all or part of the Secured 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 Secured Notes on the relevant record date to receive interest due on the relevant interest payment date.

On or after July 1, 2015, the Issuers may redeem all or a part of the Secured 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 Secured 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 July 1 of the years indicated below:

If less than all of the Secured Notes are to be redeemed at any time, the Trustee will select Secured Notes for redemption on a pro rata basis, by lot or by such other method as the Trustee deems fair and appropriate.

No Secured 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 Secured Notes to be redeemed at its registered address. Notices of redemption may not be conditional.

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

The Issuers are not required to make any mandatory redemption or sinking fund payments with respect to the Secured Notes. However, under certain circumstances, the Issuers may be required to offer to purchase the Secured Notes as described below under “—Repurchase at the Option of Holders—Change of Control” and “—Repurchase at the Option of Holders—Asset Sales.” The Company and its Restricted Subsidiaries may at any time and from time to time purchase Secured Notes in the open market or otherwise.

The Secured Indenture contains provisions related to the escrow of certain funds and providing for a special mandatory redemption of the Secured Notes in the event the AboveNet Acquisition Agreement was terminated or the AboveNet Acquisition or the Assumption was not consummated. These provisions have ceased to apply to the Secured Outstanding Notes, and will not apply to the Secured Exchange Notes, because the AboveNet Acquisition has been consummated.

Unless the Issuers have previously or concurrently delivered a redemption notice with respect to all the outstanding Secured 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 Secured Notes then outstanding, at a purchase price in cash equal to 101% of the aggregate principal amount of the Secured Notes repurchased, plus accrued and unpaid interest, if any, thereon, to the date of repurchase, subject to the rights of Holders of Secured 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 Secured 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 Notes—We may not be able to repurchase the Notes upon a change of control.”

The Change of Control purchase feature of the Secured 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 Secured 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 Secured Indenture applicable to an Offer to Purchase made by the Issuers and purchases all Secured Notes validly tendered and not withdrawn under such Offer to Purchase.

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 Secured Notes to require the Issuers to repurchase such Secured 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 Secured 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;

(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) 1.0% of total assets and (y) $10 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

(3) in the case of an Asset Sale of Collateral, all consideration from such Asset Sale that is not in the form of Cash Equivalents is pledged as Collateral to secure the Secured Notes concurrently with or promptly after the acquisition.

Any Net Available Cash received by the Company or any Restricted Subsidiary from any Asset Sale:

(1) in the case of any Asset Sale of Collateral, (A) shall be reinvested within 360 days in Replacement Assets; provided that (x) to the extent the assets subject to such Asset Sale were Collateral, such newly acquired assets shall also be Collateral and (y) the purchase of the Replacement Assets is consummated no later than (i) the 360th day after such Asset Sale or (ii) so long as a binding agreement with respect to the purchase of Replacement Assets is entered into within 360 days after the Asset Sale, 90 days after the date of such binding agreement, or (B) shall otherwise be used to make an Offer to Purchase (as described below) in accordance with the following paragraph; or

(2) in the case of any Asset Sale of assets not constituting Collateral, may be applied (A) as provided in the immediately preceding clause (1) above or (B) 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 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 Secured Indenture with respect to offers to purchase with the proceeds of sales of assets, the maximum principal amount of Secured 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 Secured 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 Secured 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 Secured Indenture, and those Excess Proceeds shall no longer constitute “Excess Proceeds.”

Except in the case of an Asset Sale of Collateral, 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 Secured 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 Secured 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 Secured Notes or any Secured 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 Secured 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 Secured 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 Secured Indenture summarized under the following headings (collectively, the “Suspended Covenants”):

If at any time the Secured 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 Secured Indenture (including in connection with performing any calculation or assessment to determine compliance with the terms of the Secured Indenture), unless and until the Secured 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 Secured 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 Secured Indenture, the Secured 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 “—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 “—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 “—Limitation on Indebtedness.” Calculations made after the Reversion Date of the amount available to be made as Restricted Payments under “—Limitation on Restricted Payments” will be made as though the covenants described under “—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 “—Limitation on Restricted Payments” to the extent set forth in such covenant.

There can be no assurance that the Secured 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”):

(1) 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);

(2) 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);

(3) 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 Secured Notes or any Secured 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

(4) 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 the Issue Date (excluding Restricted Payments permitted by clauses (2), (3), (4), (5), (6), (7), (8) and (11) of the next succeeding paragraph (B)), 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 received by the Company after the date the AboveNet Acquisition is consummated as a contribution to its common equity capital or from the issue or sale 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 the date the AboveNet Acquisition is consummated, 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

(B) The preceding provisions will not prohibit the following; provided that, in the case of clauses (7) and (8) below only, no Default has occurred and is continuing or would be caused thereby:

(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 Secured Indenture, and the redemption of any Indebtedness that is subordinated in right of payment to the Secured Notes or the Secured 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 Secured 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 Secured Notes or the Secured 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 Communications Infrastructure Investments, LLC (“CII”), the Company’s indirect parent company, to fund the repurchase, redemption or other acquisition or retirement for value of any Equity Interests of CII, 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; or, prior to the Company’s initial public offering, a distribution or dividend, directly or indirectly, to any of the Company’s direct or indirect parent companies for the purpose of enabling CII to effect a repurchase, redemption or other acquisition or retirement of the Equity Interests in CII from one or more of its equity investors that fail to comply with their funding commitments under the CII limited liability company agreement; 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 $7.5 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, $15 million;

(9) the declaration and payment of dividends on the Company’s Equity Interests (or a Restricted Payment to any direct or indirect parent to fund a payment of dividends on such entity’s Equity Interests), following the first public equity offering of such common stock after the Issue Date, of up to 6% per annum of the net cash proceeds received by (or, in the case of a Restricted Payment to a direct or indirect parent entity, contributed to the capital of) the Company in or from any such public equity offering;

(10) other Restricted Payments in an aggregate amount not to exceed $30 million; and

(11) the declaration and payment of dividends by the Issuers to, or the making of the loans to, the Parent in amounts required for the 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 Issuers and their Restricted Subsidiaries and (ii) required to be paid by the Parent, and only for so long as the Issuers are treated as pass-through entities 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 the Issuers and their Restricted Subsidiaries would be required to pay in respect of its foreign, federal, state and local taxes for such fiscal year were the Issuers and their 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 the Parent to the extent such salaries, bonuses and other benefits are attributable to the ownership or operation of the Issuer and its Restricted Subsidiaries; (d) general corporate operating and overhead costs and expenses of the Parent to the extent such costs and expenses are attributable to the ownership or operation of the Issuer and its Restricted Subsidiaries; and (e) amounts required for the Parent to pay fees and expenses incurred by the Parent related to the maintenance of the Parent of its corporate or other entity existence.

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.

For the purposes of this covenant, any payment made on or after March 12, 2010, but prior to the Issue Date, shall be deemed to be a “Restricted Payment” to the extent that such payment would have been a Restricted Payment had the Secured Indenture been in effect at the time of such payment (and, to the extent that such Restricted Payment was permitted by clauses (1) through (11) above, such Restricted Payment may be deemed by the Company to have been made pursuant to such clause).

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 5.25 to 1.

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 New 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 $2,000 million;

(3) the Incurrence by the Company and the Guarantors of Indebtedness represented by the Secured Notes (other than Additional Secured Notes), the Unsecured Notes and the Secured Exchange Notes (as defined below) in respect thereof and the related Secured Note Guarantees;

any Indebtedness Incurred pursuant to this clause (4), not to exceed, at any time outstanding, the sum of (i) $100 million and (ii) 3.0% of the consolidated total assets of the Company (excluding Unrestricted Subsidiaries and determined as of the end of the most recent quarter of the Company for which internal financial statements are available) at any time outstanding;

(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 Senior Secured 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 Secured Notes, in the case of the Company, or the Secured Note Guarantee, in the case of a Guarantor; and

(b) (i) 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 Secured 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 $100 million; 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 New Credit Facilities outstanding on the date of the Assumption, 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 Secured 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 Secured Notes or such Guarantor’s Secured Note Guarantee, as the case may be, at least to the same extent. For purposes of the Secured 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.

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 New Credit Facilities or the Security Documents as in effect on the date of the Assumption 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 New Credit Facilities or the Security Documents as in effect on the date of the Assumption or Existing Indebtedness or such other agreements as in effect on the Issue Date;

(2) set forth in the Secured Indenture, the Secured Notes and the Secured 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 Senior Secured 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 Secured 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 Secured Notes.

The Company. 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 Secured Notes is a corporation organized or existing under such laws and (ii) assumes all the obligations of such Issuer under the Secured Notes, the Secured Indenture and the Security Documents 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 Secured Note Guarantee will apply to the obligations of such Issuer or the surviving Person in accordance with the Secured Notes and the Secured Indenture;

(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 (including any supplement to any Security Document if required in connection with such transaction) comply with this covenant and that all conditions precedent provided for in the Secured Indenture relating to such transaction have been complied with;

(6) such Issuer or the surviving entity, as applicable, promptly causes such amendments, supplements or other instruments to be executed, delivered, filed and recorded, as applicable, in such jurisdictions as may be reasonably required by applicable law to preserve and protect the Lien of the Security Documents on the Collateral owned by or transferred to such Issuer or the surviving entity;

(7) the Collateral owned by or transferred to such Issuer or the surviving entity, as applicable, shall (a) continue to constitute Collateral under the Secured Indenture and the Security Documents, (b) be subject to the Lien in favor of the Collateral Agent for the benefit of the Trustee and the Holders of the Secured Notes, and (c) not be subject to any Lien other than Permitted Liens; and

(8) the property and assets of the Person which is merged or consolidated with or into such Issuer or the surviving entity, as applicable, to the extent that they are property or assets or of the types which would constitute Collateral under the Security Documents, shall be treated as After-Acquired Property and such Issuer or the surviving entity shall take such action as may be reasonably necessary to cause such property and assets to be made subject to the Lien of the Security Documents in the manner and to the extent required in the Secured Indenture;

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 Secured 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 Secured Indenture with the same effect as if such successor Person had been named as an Issuer in the Secured Indenture. In the event of any such transfer, the predecessor will be released and discharged from all liabilities and obligations in respect of the Secured Notes and the Secured 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 Secured Notes and the Unsecured 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.”

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 Secured Indenture, including its Secured Note Guarantee, and the Security Documents pursuant to a supplemental indenture satisfactory to the Trustee; provided that

(A) the Guarantor or the surviving entity, as applicable, promptly causes such amendments, supplements or other instruments to be executed, delivered, filed and recorded, as applicable, in such jurisdictions as may be reasonably required by applicable law to preserve and protect the Lien of the Security Documents on the Collateral owned by or transferred to the Guarantor or the surviving entity;

(B) the Collateral owned by or transferred to the Guarantor or the surviving entity, as applicable, shall (x) continue to constitute Collateral under the Secured Indenture and the Security Documents, (y) be subject to the Lien in favor of the Collateral Agent for the benefit of the Trustee and the Holders of the Secured Notes, and (z) not be subject to any Lien other than Permitted Liens; and

(C) the property and assets of the Person which is merged or consolidated with or into the Guarantor or the surviving entity, as applicable, to the extent that they are property or assets or of the types which would constitute Collateral under the Security Documents, shall be treated as After-Acquired Property and the Guarantor or the surviving entity shall take such action as may be reasonably necessary to cause such property and assets to be made subject to the Lien of the Security Documents in the manner and to the extent required in the Secured Indenture; 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”), 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 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 $50 million, 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:

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

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

(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 comprising Collateral if the aggregate amount of such assets or properties does not to exceed $50,000,000, and provided further that the Company or any Restricted Subsidiary may enter into a Sale and Leaseback Transaction with respect to assets or properties other than Collateral 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 Secured 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 Secured 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 Secured Indenture, the Issuers will be in default under the Secured 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 date of the Assumption, then that newly acquired or created Domestic Subsidiary must become a Guarantor and (i) execute a supplemental indenture, (ii) deliver an Opinion of Counsel to the Trustee, (iii) execute supplements to the applicable Security Documents in order to grant a Lien in the Collateral owned by such entity to the same extent as that set forth in the Secured Indenture and the Security Documents, in each case, within 30 days following such acquisition or creation and (iv) take all actions required by the Security Documents to perfect such Lien. 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 Secured 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 Secured Notes for or as an inducement to any consent, waiver or amendment of any of the terms or provisions of the Secured Indenture or the Secured 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 Secured 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:

“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, 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 Secured 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.

(1) default for 30 days in the payment when due of interest on the Secured Notes;

(2) default in payment when due (whether at maturity, upon acceleration, redemption or otherwise) of the principal of, or premium, if any, on the Secured 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 Secured Notes outstanding to comply with any of the other agreements in the Secured Indenture or under the Security Documents;

(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 $40 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 $40 million, which judgments are not paid, discharged or stayed for a period of 90 days;

(7) except as permitted by the Secured Indenture, any Secured 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 Secured Note Guarantee;

(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); and

(9) unless all of the Collateral has been released from the Liens in accordance with the provisions of the Security Documents, (i) default by any Issuer or any Guarantor in the performance of any obligation under the Security Documents which adversely affects the enforceability, validity, perfection or priority of the Liens securing the Secured Notes on a material portion of the Collateral, (ii) the repudiation or disaffirmation by the any Issuer or any Guarantor of any of its material obligations under the Security Documents or (iii) the determination in a judicial proceeding that the Security Documents are unenforceable or invalid against any Issuer or any Guarantor party thereto for any reason with respect to a material portion of the Collateral and, in the case of any event described in subclauses (i) through (iii), such default, repudiation, disaffirmation or determination is not rescinded, stayed, or waived by the Persons having such authority pursuant to the Security Documents or otherwise cured within 60 days.

In the case of an Event of Default described in clause (8) above, all outstanding Secured 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 Secured Notes may declare all the Secured Notes to be due and payable immediately by notice in writing to the Company specifying the Event of Default.

Holders of the Secured Notes may not enforce the Secured Indenture or the Secured Notes except as provided in the Secured Indenture. Subject to certain limitations, Holders of a majority in principal amount of the then-outstanding Secured Notes may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders of the Secured 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 Secured Notes then outstanding by notice to the Trustee may on behalf of the Holders of all of the Secured Notes waive any existing Default or Event of Default and its consequences under the Secured Indenture except a continuing Default or Event of Default in the payment of premium or interest on, or the principal of, the Secured Notes. Subject to the terms of the Intercreditor Agreement, the Security Documents and certain restrictions, the Holders of a majority in principal amount of the then-outstanding Secured Notes will have the right to direct the time, method and place of conducting any proceeding for exercising any remedy available to the Trustee or the Collateral Agent. However, the Trustee and the Collateral Agent may refuse to follow any direction that conflicts with law or the Secured Indenture, that may involve the Trustee’s or the Collateral Agent’s personal liability, or that the Trustee or the Collateral Agent determines in good faith may be unduly prejudicial to the rights of Holders of Secured 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 Secured Notes. A Holder may not pursue any remedy with respect to the Secured Indenture or the Secured 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 Secured 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 Secured Notes do not give the Trustee a direction that is inconsistent with the request.

Notwithstanding the foregoing, in no event may any Holder enforce any Lien of the Collateral Agent pursuant to the Security Documents.

However, such limitations do not apply to the right of any Holder of a Secured Note to receive payment of the principal of, premium, if any, or interest on, such Secured Note or to bring suit for the enforcement of any such payment, on or after the due date expressed in the Secured 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 Secured 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 Secured Notes, the Secured Indenture, the Secured Note Guarantees, or the Security Documents or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder of Secured Notes, by accepting a Secured Note, waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Secured 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 Secured Notes and all obligations of the Guarantors discharged with respect to their Secured Note Guarantees (“Legal Defeasance”) except for:

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

(2) the Issuers’ obligations with respect to the Secured Notes concerning issuing temporary Secured Notes, registration of Secured Notes, mutilated, destroyed, lost or stolen Secured 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 Secured 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 Secured 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 Secured Notes.

If the Issuers exercise the legal defeasance or covenant defeasance option, the Liens on the Collateral will be released and the Secured Note Guarantees in effect at such time will terminate.

(1) the Company must irrevocably deposit with the Trustee, in trust, for the benefit of the Holders of the Secured 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 Secured Notes on the Stated Maturity or on the applicable redemption date, as the case may be, and the Issuers must specify whether the Secured 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 Secured 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 Secured 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;

(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 Secured Notes are to be redeemed prior to their Stated Maturity, the Issuers must deliver to the Trustee irrevocable instructions to redeem all of the Secured 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 Secured Indenture will be discharged and will cease to be of further effect as to all Secured Notes issued thereunder, when:

(a) all Secured Notes that have been authenticated (except lost, stolen or destroyed Secured Notes that have been replaced or paid and Secured 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 Secured 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, 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 Secured 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 Secured Indenture; and

(4) the Issuers have delivered irrevocable instructions to the Trustee under the Secured Indenture to apply the deposited money toward the payment of the Secured 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 Secured Indenture, the Secured Notes and the Intercreditor Agreement may be amended or supplemented with the consent of the Holders of at least a majority in principal amount of the Secured Notes then outstanding (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, Secured Notes), and any existing default or compliance with any provision of the Secured Indenture, the Secured Notes and the Intercreditor Agreement may be waived with the consent of the Holders of a majority in principal amount of the then-outstanding Secured Notes (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, Secured Notes).

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

(1) reduce the principal amount of Secured 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 Secured Note;

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

(4) change the optional redemption dates or optional redemption prices of the Secured 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 Secured Notes (except, upon a rescission of acceleration of the Secured Notes by the Holders of at least a majority in aggregate principal amount of the Secured 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 Secured Indenture;

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

(9) impair the right to institute suit for the enforcement of any payment on or with respect to the Secured Notes or the Secured 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 Secured Note Guarantees,” consent to the assignment or transfer by any Issuers or any Guarantor of any of their rights or obligations under the Secured Indenture.

In addition, any amendment to, or waiver of, any provision of the Secured Indenture or any Security Document that has the effect of releasing all or substantially all of the Collateral from the Liens of the Secured Notes will require consent of the Holders of at least 75% in aggregate principal amount of the Secured Notes then outstanding.

Notwithstanding the preceding, without the consent of any Holder of Secured Notes, the Issuers, the Guarantors, the Trustee and the Collateral Agent may amend or supplement the Secured Indenture, the Secured Notes, the Intercreditor Agreement or the Security Documents:

(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 Secured Notes in addition to or in place of certificated Secured Notes;

(3) to provide for the assumption of any Issuer’s or any Guarantor’s obligations to Holders of Secured Notes in accordance with the Secured 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 Secured 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 Secured Indenture of any such Holder;

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

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

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

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

(9) to conform the Secured Indenture, the Secured Notes, the Intercreditor Agreement or any Collateral Agreement to any provision of this “Description of the Senior Secured First-Priority Notes” to the extent such provision is intended to be a verbatim recitation thereof;

(10) to amend the Intercreditor Agreement to add additional lenders holding Additional Pari Passu Obligations permitted under the Secured Indenture, the New Credit Facilities, the Intercreditor Agreement and any Additional Pari Passu Agreements then in effect; or

If the Trustee becomes a creditor of any Issuer or any Guarantor, the Secured 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 Secured 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 Secured Indenture at the request of any Holder of Secured Notes, unless such Holder will have offered to the Trustee security and indemnity satisfactory to it against any loss, liability or expense.

Subject to certain exceptions, the Secured Indenture provides that neither the Trustee not the Collateral Agent shall be responsible for the existence, genuineness, value or protection of any Collateral for the legality, effectiveness or sufficiency of any Security Document, or for the creation, perfection, priority, sufficiency or protection of any Lien created by a Note.

The Secured Notes initially will be represented by one or more notes in registered, global form without interest coupons (collectively, the “Global Notes”). The Global Notes will be deposited upon issuance with the Trustee as custodian for The Depository Trust Company (“DTC”), in Los Angeles, California, 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 interests in the Global Notes may be held through the Euroclear System (“Euroclear”) and Clearstream Banking, S.A. (“Clearstream”) (as indirect participants in DTC).

Except as set forth below, the 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 Global Notes may be exchanged for Secured Notes in certificated form. See “—Exchange of Global Notes for Certificated 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 Global Notes who are Participants in DTC’s system may hold their interests therein directly through DTC. Investors in the 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 may hold interests in the 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 Secured 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 Secured Indenture. Under the terms of the Secured Indenture, the Issuers and the Trustee will treat the Persons in whose names the Secured Notes, including the 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:

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 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 Secured 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 Secured 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 Secured 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 Secured Notes only at the direction of one or more Participants to whose account DTC has credited the interests in the Global Notes and only in respect of such portion of the aggregate principal amount of the Secured Notes as to which such Participant or Participants has or have given such direction. However, if there is an Event of Default under the Secured Notes, DTC reserves the right to exchange the 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 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 Global Note is exchangeable for definitive notes in registered certificated form (“Certificated Notes”) if:

(1) DTC (a) notifies the Issuers that it is unwilling or unable to continue as depositary for the 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 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 Secured Notes.

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

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

The Issuers will make payments in respect of the Secured Notes represented by the Global Notes (including principal, premium, if any, and 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 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 Secured Notes represented by the Global Notes are expected to trade in DTC’s Same-Day Funds Settlement System, and any permitted secondary market trading activity in such Secured Notes will, therefore, be required by DTC to be settled in immediately available funds. The Issuers expect that secondary trading in any Certificated 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.

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

Any Unsecured Outstanding Notes that remain outstanding after the completion of the exchange offer, together with the Unsecured Exchange Notes issued in connection with the exchange offer, will be treated as a single class of notes under the Unsecured Indenture.

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

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

As of March 31, 2012, on an as adjusted basis after giving effect to the issuance of the Unsecured Notes and the Secured Notes, the use of proceeds thereof, and the entry into the New Credit Facilities, and after excluding intercompany balances and intercompany guarantees:

As of the date of this prospectus, all of the Company’s Domestic Subsidiaries (other than Zayo Capital, Inc., the co-issuer) are Guarantors and guarantee the Unsecured Notes. However, the Unsecured Indenture does not require any future Foreign Subsidiaries to provide a Unsecured Note Guarantee unless such Foreign Subsidiary guarantees other Indebtedness of the Issuers. Certain Subsidiaries acquired in the AboveNet Acquisition are Foreign Subsidiaries of the Company. Accordingly, they and any other future Foreign Subsidiaries of the Company may not be Guarantors. 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 Domestic 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 Unsecured Indenture. Further, Unrestricted Subsidiaries will not Guarantee the Unsecured Notes.

Although the Unsecured 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 Unsecured Notes will mature on July 1, 2020. The Issuers will issue up to $499.4 million aggregate principal amount of Unsecured Notes in the exchange offer. Subject to the covenant described under “—Certain

Covenants—Limitation on Indebtedness,” the Issuers are permitted to issue additional Unsecured Notes under the Unsecured Indenture (“Additional Unsecured Notes”). The Unsecured Notes and any Additional Unsecured Notes that are issued will be treated as a single class under the Unsecured Indenture, including with respect to waivers, amendments, redemptions and Offers to Purchase. The Additional Unsecured Notes may be issued at different prices from the original issue price of the Unsecured Notes. Unless the context otherwise requires, references to the “Unsecured Notes” for all purposes under the Unsecured Indenture and in this “Description of the Unsecured Notes” include any Additional Unsecured Notes that are issued.

Interest on the Unsecured 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 10.125%, and will be payable semi annually in arrears on January 1 and July 1 of each year, commencing on January 1, 2013. Interest will be payable to Holders of record on each Unsecured Note in respect of the principal amount thereof outstanding as of the immediately preceding December 15 or June 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 Unsecured Notes. In no event will the rate of interest on the Unsecured Notes be higher than the maximum rate permitted by applicable law.

The Unsecured 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 Unsecured Notes will be initially in the form of one or more global notes (the “Global Notes”). The Global Notes will be deposited with the Trustee as custodian for the Depository Trust Company (“DTC”). Ownership of interests in the 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 Unsecured Indenture will provide for the issuance of definitive registered Unsecured Notes in certain circumstances. Please see the section entitled “—Book Entry, Delivery and Form.”

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

A Holder may transfer or exchange Unsecured Notes in accordance with the Unsecured 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 Unsecured 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 Unsecured Note selected for redemption. Also, the Issuers are not required to transfer or exchange any Unsecured Note for a period of 15 days before a selection of Unsecured Notes to be redeemed.

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 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.

On the date of the Assumption and upon joining the Unsecured Indenture, the Initial Guarantors jointly and severally agreed to guarantee the due and punctual payment of all amounts payable under the Unsecured Notes, including principal, premium, if any, and interest. The Unsecured Indenture will require 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 Unsecured Note Guarantee. The ability of any future Domestic Subsidiaries to provide a Unsecured Note Guarantee may be subject to prior approval by certain State PUCs. See “—Certain Covenants—Future Subsidiary Unsecured Note Guarantees.”

Each Unsecured Note Guarantee of a Guarantor will be the Guarantor’s senior obligation. The Unsecured Indenture states that each Guarantor under its Unsecured 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 Unsecured 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 Secured Notes and the Unsecured 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 Unsecured Note Guarantee will be entitled to contribution from any other Guarantor.

A Unsecured 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 Unsecured Indenture;

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

(4) upon a Legal Defeasance or satisfaction and discharge of the Unsecured 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 Unsecured Notes then outstanding and all other obligations under the Unsecured Indenture and the Unsecured Notes then due and owing.

Upon any occurrence giving rise to a release of a Unsecured 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 Unsecured Note Guarantee. Neither the Issuers nor any Guarantor will be required to make a notation on the Unsecured Notes to reflect any Unsecured Note Guarantee or any such release, termination or discharge.

At any time prior to July 1, 2015, the Issuers may redeem up to 35% of the aggregate principal amount of Unsecured Notes issued under the Unsecured Indenture (including any Additional Unsecured Notes) at a redemption price of 110.125% of the principal amount thereof, plus accrued and unpaid interest, if any, thereon to the redemption date, subject to the rights of Holders of Unsecured 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 65% of the aggregate principal amount of Unsecured Notes issued under the Unsecured Indenture (including any Additional Unsecured Notes) remains outstanding immediately after the occurrence of such redemption (excluding Unsecured 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 July 1, 2016, the Issuers may redeem all or part of the Unsecured 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 Unsecured Notes on the relevant record date to receive interest due on the relevant interest payment date.

On or after July 1, 2016, the Issuers may redeem all or a part of the Unsecured 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 Unsecured 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 July 1 of the years indicated below:

If less than all of the Unsecured Notes are to be redeemed at any time, the Trustee will select Unsecured Notes for redemption on a pro rata basis, by lot or by such other method as the Trustee deems fair and appropriate.

No Unsecured 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 Unsecured Notes to be redeemed at its registered address. Notices of redemption may not be conditional.

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

The Issuers are not required to make any mandatory redemption or sinking fund payments with respect to the Unsecured Notes. However, under certain circumstances, the Issuers may be required to offer to purchase the Unsecured Notes as described below under “—Repurchase at the Option of Holders—Change of Control” and “—Repurchase at the Option of Holders—Asset Sales.” The Company and its Restricted Subsidiaries may at any time and from time to time purchase Unsecured Notes in the open market or otherwise.

The Unsecured Indenture contains provisions related to the escrow of certain funds and providing for a special mandatory redemption of the Unsecured Notes in the event the AboveNet Acquisition Agreement was terminated or the AboveNet Acquisition or the Assumption was not consummated. These provisions have ceased to apply to the Unsecured Outstanding Notes, and will not apply to the Unsecured Exchange Notes, because the AboveNet Acquisition has been consummated.

Unless the Issuers have previously or concurrently delivered a redemption notice with respect to all the outstanding Unsecured 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 Unsecured Notes then outstanding, at a purchase price in cash equal to 101% of the aggregate principal amount of the Unsecured Notes repurchased, plus accrued and unpaid interest, if any, thereon, to the date of repurchase, subject to the rights of Holders of Unsecured 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 Unsecured 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 Notes—We may not be able to repurchase the Notes upon a change of control.”

The Change of Control purchase feature of the Unsecured 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 Unsecured 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 Unsecured Indenture applicable to an Offer to Purchase made by the Issuers and purchases all Unsecured Notes validly tendered and not withdrawn under such Offer to Purchase.

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 Secured Notes and the Unsecured 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:

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 the Senior Secured Indenture and 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 Unsecured Indenture with respect to offers to purchase with the proceeds of sales of assets, the maximum principal amount of Unsecured 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 the Secured Notes or 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 Unsecured 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 Unsecured 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 Unsecured 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 Unsecured 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 Unsecured 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 Unsecured Notes or any Unsecured 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 Unsecured 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 Unsecured 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 Unsecured Indenture summarized under the following headings (collectively, the “Suspended Covenants”):

If at any time the Unsecured 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 Unsecured Indenture (including in connection with performing any calculation or assessment to determine compliance with the terms of the Unsecured Indenture), unless and until the Unsecured 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 Unsecured 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 Unsecured Indenture, the Unsecured 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 Unsecured 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”):

(3) 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 Unsecured Notes or any Unsecured 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

(4) 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;

(B) The preceding provisions will not prohibit the following; provided that, in the case of clauses (7) and (8) below only, no Default has occurred and is continuing or would be caused thereby:

(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 Unsecured Indenture, and the redemption of any Indebtedness that is subordinated in right of payment to the Unsecured Notes or the Unsecured 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 Unsecured 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 Unsecured Notes or the Unsecured 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;

(9) the declaration and payment of dividends on the Company’s Equity Interests (or a Restricted Payment to any direct or indirect parent entity to fund a payment of dividends on such entity’s Equity Interests), following the first public equity offering of such common stock after the Issue Date, of up to 6% per annum of the net cash proceeds received by (or, in the case of a Restricted Payment to a direct or indirect parent entity, contributed to the capital of) the Company in or from any such public equity offering;

(10) other Restricted Payments in an aggregate amount not to exceed $30 million; and

For the purposes of this covenant, any payment made on or after March 12, 2010, but prior to the Issue Date, shall be deemed to be a “Restricted Payment” to the extent that such payment would have been a Restricted Payment had the Unsecured Indenture been in effect at the time of such payment (and, to the extent that such Restricted Payment was permitted by clauses (1) through (11) above, such Restricted Payment may be deemed by the Company to have been made pursuant to such clause).

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 Unsecured Notes (other than Additional Unsecured Notes), the Secured Notes and the Unsecured Exchange Notes (as defined below) in respect thereof and the related Unsecured 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 sum of (i) $100 million and (ii) 3.0% of the consolidated total assets of the Company (excluding Unrestricted Subsidiaries and determined as of the end of the most recent quarter of the Company for which internal financial statements are available) at any time outstanding;

(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 Unsecured 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 Unsecured Notes, in the case of the Company, or the Unsecured 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;

(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 Unsecured 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;

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 Unsecured 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 Unsecured Notes or such Guarantor’s Unsecured Note Guarantee, as the case may be, at least to the same extent. For purposes of the Unsecured 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 Unsecured Indenture and the Unsecured 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:

(1) existing under, by reason of or with respect to the New Credit Facilities as in effect on the date of the Assumption 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 New Credit Facilities or the Security Documents as in effect on the date of the Assumption or Existing Indebtedness or such other agreements, as the case may be, as in effect on the Issue Date;

(2) set forth in the Unsecured Indenture, the Unsecured Notes and the Unsecured 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;

(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 Unsecured Notes is a corporation organized or existing under such laws and (ii) assumes all the obligations of such Issuer under the Unsecured Notes and the Unsecured 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 Unsecured Note Guarantee will apply to the obligations of such Issuer or the surviving Person in accordance with the Unsecured Notes and the Unsecured 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 Unsecured 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 Unsecured 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 Unsecured Indenture with the same effect as if such successor Person had been named as an Issuer in the Unsecured Indenture. In the event of any such transfer, the predecessor will be released and discharged from all liabilities and obligations in respect of the Secured Notes and the Secured 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 Unsecured Indenture, including its Unsecured Note Guarantee, pursuant to a supplemental indenture satisfactory to the Trustee; or

(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

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

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

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

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

(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 Unsecured 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 Unsecured 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 Unsecured Indenture, the Issuers will be in default under the Unsecured 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 Unsecured 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 Unsecured Notes for or as an inducement to any consent, waiver or amendment of any of the terms or provisions of the Unsecured Indenture or the Unsecured 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 Unsecured 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.

(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.

In addition, the Issuers and the Guarantors have agreed that, for so long as any Unsecured 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.

(1) default for 30 days in the payment when due of interest on the Unsecured Notes;

(2) default in payment when due (whether at maturity, upon acceleration, redemption or otherwise) of the principal of, or premium, if any, on the Unsecured 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 Unsecured Notes outstanding to comply with any of the other agreements in the Unsecured 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 Unsecured Indenture, any Unsecured 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 Unsecured Note Guarantee; and

In the case of an Event of Default described in clause (8) above, all outstanding Unsecured 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 Unsecured Notes may declare all the Unsecured Notes to be due and payable immediately by notice in writing to the Company specifying the Event of Default.

Holders of the Unsecured Notes may not enforce the Unsecured Indenture or the Unsecured Notes except as provided in the Unsecured Indenture. Subject to certain limitations, Holders of a majority in principal amount of the then-outstanding Unsecured Notes may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders of the Unsecured 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 Unsecured Notes then outstanding by notice to the Trustee may on behalf of the Holders of all of the Unsecured Notes waive any existing Default or Event of Default and its consequences under the Unsecured Indenture except a continuing Default or Event of Default in the payment of premium or interest on, or the principal of, the Unsecured Notes. However, the Trustee may refuse to follow any direction that conflicts with law or the Unsecured 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 Unsecured 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 Unsecured Notes. A Holder may not pursue any remedy with respect to the Unsecured Indenture or the Unsecured 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 Unsecured 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 Unsecured 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 Unsecured Note to receive payment of the principal of, premium, if any, or interest on, such Unsecured Note or to bring suit for the enforcement of any such payment, on or after the due date expressed in the Unsecured 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 Unsecured 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 Unsecured Notes, the Unsecured Indenture, or the Unsecured Note Guarantees, or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder of Unsecured Notes, by accepting a Unsecured Note, waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Unsecured 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 Unsecured Notes and all obligations of the Guarantors discharged with respect to their Unsecured Note Guarantees (“Legal Defeasance”) except for:

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

(2) the Issuers’ obligations with respect to the Unsecured Notes concerning issuing temporary Unsecured Notes, registration of Unsecured Notes, mutilated, destroyed, lost or stolen Unsecured 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 Unsecured 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 Unsecured 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 Unsecured Notes.

(1) the Company must irrevocably deposit with the Trustee, in trust, for the benefit of the Holders of the Unsecured 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 Unsecured Notes on the Stated Maturity or on the applicable redemption date, as the case may be, and the Issuers must specify whether the Unsecured Notes are being defeased to maturity or to a particular redemption date;

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 Unsecured 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 Unsecured Notes are to be redeemed prior to their Stated Maturity, the Issuers must deliver to the Trustee irrevocable instructions to redeem all of the Unsecured 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 Unsecured Indenture will be discharged and will cease to be of further effect as to all Unsecured Notes issued thereunder, when:

(a) all Unsecured Notes that have been authenticated (except lost, stolen or destroyed Unsecured Notes that have been replaced or paid and Unsecured 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 Unsecured 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, 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 Unsecured 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;

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

(4) the Issuers have delivered irrevocable instructions to the Trustee under the Unsecured Indenture to apply the deposited money toward the payment of the Unsecured 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 Unsecured Indenture and the Unsecured Notes may be amended or supplemented with the consent of the Holders of at least a majority in principal amount of the Unsecured Notes then outstanding (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, Unsecured Notes), and any existing default or compliance with any provision of the Unsecured Indenture and the Unsecured Notes may be waived with the consent of the Holders of a majority in principal amount of the then-outstanding Unsecured Notes (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, Unsecured Notes).

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

(1) reduce the principal amount of Unsecured 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 Unsecured Note;

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

(4) change the optional redemption dates or optional redemption prices of the Unsecured 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 Unsecured Notes (except, upon a rescission of acceleration of the Unsecured Notes by the Holders of at least a majority in aggregate principal amount of the Unsecured 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 Unsecured Indenture;

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

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

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

Notwithstanding the preceding, without the consent of any Holder of Unsecured Notes, the Issuers, the Guarantors and the Trustee may amend or supplement the Unsecured Indenture or the Unsecured 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 Notes in addition to or in place of certificated Notes;

(3) to provide for the assumption of any Issuer’s or any Guarantor’s obligations to Holders of Unsecured Notes in accordance with the Unsecured 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 Unsecured 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 Unsecured Indenture of any such Holder;

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

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

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

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

(9) to conform the Unsecured Indenture or the Unsecured Notes to any provision of this “Description of the Unsecured 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 Unsecured 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 Unsecured 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 Unsecured Indenture at the request of any Holder of Unsecured Notes, unless such Holder will have offered to the Trustee security and indemnity satisfactory to it against any loss, liability or expense.

The Unsecured Notes initially will be represented by one or more notes in registered, global form without interest coupons (collectively, the “Global Notes”). The Global Notes will be deposited upon issuance with the Trustee as custodian for The Depository Trust Company (“DTC”), in Los Angeles, California, 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 interests in the Global Notes may be held through the Euroclear System (“Euroclear”) and Clearstream Banking, S.A. (“Clearstream”) (as indirect participants in DTC).

Except as set forth below, the 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 Global Notes may be exchanged for Unsecured Notes in certificated form. See “—Exchange of Global Notes for Certificated 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

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 Unsecured Indenture. Under the terms of the Unsecured Indenture, the Issuers and the Trustee will treat the Persons in whose names the Unsecured Notes, including the 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 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 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 Unsecured 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 Unsecured 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 Unsecured 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 Unsecured Notes only at the direction of one or more Participants to whose account DTC has credited the interests in the Global Notes and only in respect of such portion of the aggregate principal amount of the Unsecured Notes as to which such Participant or Participants has or have given such direction. However, if there is an Event of Default under the Unsecured Notes, DTC reserves the right to exchange the Global Notes for legended notes in certificated form, and to distribute such notes to its Participants.

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

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

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

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

The Issuers will make payments in respect of the Unsecured Notes represented by the Global Notes (including principal, premium, if any, and 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 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 Unsecured Notes represented by the Global Notes are expected to trade in DTC’s Same-Day Funds Settlement System, and any permitted secondary market trading activity in such Unsecured Notes will, therefore, be required by DTC to be settled in immediately available funds. The Issuers expect that secondary trading in any Certificated Notes will also be settled in immediately available funds.

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.
