Overview

We are the leading global provider of network-neutral data center and colocation services. Platform Equinix™ combines state-of-the-art International Business Exchange^® (IBX^®) data centers, a global footprint and unique ecosystems. Together these components accelerate business growth for our customers by safeguarding their infrastructure, housing their assets and applications closer to users to improve performance and enabling them to collaborate with the widest variety of partners and customers. More than 3,350 enterprise, cloud, digital content and financial companies connect to more than 650 network service providers and rely on Platform Equinix to grow their business, improve application performance and protect their vital digital assets. We operate in 37 strategic markets across the Americas, EMEA and Asia-Pacific regions and continue to invest in expanding our platform to power customer growth. For the year ended December 31, 2010 and the three months ended March 31, 2011 we had revenues of $1,220.3 million and $363.0 million, net income of $36.9 million and $25.1 million and adjusted EBITDA of $544.8 million and $167.3 million, respectively. For the twelve months ended March 31, 2011, we had revenues of $1,334.7 million, net income of $47.8 million and adjusted EBITDA of $594.8 million. For a discussion of our primary non-GAAP metric, adjusted EBITDA, including a reconciliation to GAAP financial measures, see our non-GAAP financial measures discussion in “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in the 2010 Annual Report and the Q1 2011 Report, each of which is incorporated by reference in this prospectus.

Our services are primarily comprised of colocation, interconnection and managed IT infrastructure services.

•

Colocation services include cabinets, power, operations space and storage space for customers’ colocation needs.

•

Interconnection services include cross connects, as well as switch ports on the Equinix Internet Exchange and Equinix Carrier Ethernet Exchange services. These services provide scalable and reliable connectivity that allows customers to exchange traffic directly with the service provider of their choice or directly with each other, creating a performance-optimized business ecosystem for the exchange of data between strategic partners.

•

Managed IT infrastructure services allow customers to leverage our significant telecommunications expertise, maximize the benefits of our IBX data centers and optimize their infrastructure and resources.

Our network-neutral business model contributes to our success in the market. We offer customers direct interconnection to an aggregation of bandwidth providers, rather than focusing on selling a particular network, including the world’s top carriers, Internet Service Providers (ISPs), broadband access networks (DSL / cable) and international carriers. Neutrality also means our customers can choose to buy from, or partner with, leading companies across our five targeted verticals. These include:

•

Network Providers (AT&T, British Telecom, Comcast, Level 3 Communications, NTT, Qwest, SingTel, Sprint, Verizon Business)

•

Cloud and IT Services (Amazon.com, Carpathia, Microsoft, Citrix, IBM, Salesforce.com, Voxel.net, WebEx)

•

Content Providers (eBay, DIRECTV, Facebook, Google, Hulu, SONY, Yahoo!, Zynga)

•

Enterprise (Booz Allen Hamilton, Barnes & Noble, Bechtel, Deloitte & Touche, GAP, The McGraw-Hill Companies, United Stationers Inc., Wellpoint)

•

Financial Companies (ACTIV Financial, Bloomberg, BOX, CBOE, DirectEdge, JP Morgan Chase, Quantlab Financial, Thomson Reuters)

Internet connectivity and the ability to efficiently distribute digital content or services across multiple networks to a global audience are core strategic requirements to an increasing number of businesses today. Customer demand for highly reliable, secure, network-neutral data center and colocation facilities continues to expand more rapidly than the supply of facilities available in the industry. We believe the factors contributing to the continued increase in demand for our services include:

•

The continuing growth of consumer Internet traffic from new bandwidth-intensive services, such as video, VoIP, social media, mobile data, gaming, data-rich media, Ethernet and wireless services.

•

Significant increases in power and cooling requirements for today’s data center equipment. Servers have increased the overall level of power consumed and heat generation by more than two times since 2000 and many legacy-built data centers are unable to accommodate new power and cooling demands.

•

The growth of enterprise applications delivered across communications networks, such as Software-as-a-Service (SaaS), and disaster recovery, and the adoption of cloud computing technology services.

•

The financial services market is experiencing tremendous growth with the shift to electronic trading and increased volume of peak messages (transactions per second), requiring optimized data exchange through business ecosystems.

•

The growth of “proximity communities” that rely on immediate physical colocation and interconnection with their strategic partners and customers, such as financial exchange ecosystems for electronic trading and settlement.

•

The high capital costs associated with building and maintaining “in-sourced” data centers creates an opportunity for capital savings by leveraging an outsourced colocation model.

The supply and demand imbalance in the industry has, to date, created a favorable pricing environment for us, as well as an opportunity to increase market share. We have gained many customers that have outgrown their existing data centers or that have realized the benefits of a network-neutral model and the ability to create their own optimized business ecosystems for the exchange of data. Strategically, we will continue to look at attractive opportunities to grow market share and selectively expand our footprint and service offerings. We continue to leverage our global reach and depth to differentiate based upon our ability to support truly global customer requirements in all our markets.

Our Value Proposition

More than 3,900 companies, including a diversified mix of cloud and IT service providers, content providers, enterprises, financial companies, and network service providers, currently operate within our IBX data centers. These companies derive specific value from the following elements of our service offering:

•

Comprehensive global service: With over 90 IBX data centers in 37 markets in the Americas, EMEA and Asia-Pacific regions, we offer a consistent global service.

•

Premium data centers: Our IBX data centers feature advanced design, security, power and cooling elements to provide customers with industry-leading reliability. While others in the market have business models that include additional offerings, we are focused on data center services and interconnection as our core competencies.

•

Dynamic business ecosystems: Our network-neutral model has enabled us to attract a critical mass of networks that, in turn, attracts other businesses seeking to interconnect within a single location. This ecosystem model, versus connecting to multiple partners in disparate locations, reduces costs and optimizes the performance of data exchange. As we grow and attract an even more diversified base of customers, the value of our IBX data center offering increases.

•

Improved economics: Customers seeking to outsource their data center operations rather than build their own capital-intensive data centers enjoy significant capital cost savings in this credit-challenged economic environment. Customers also benefit from improved economics on account of the broad access to networks that we provide. Rather than purchasing costly local loops from multiple transit providers, customers can connect directly to more than 650 networks inside our IBX data centers.

•

Leading insight: With more than 10 years of industry experience, we have a specialized staff of industry experts who helped build and shape the interconnection infrastructure of the Internet. This specialization and industry knowledge base offer customers a unique consultative value and a competitive advantage.

Our Strategy

Our objective is to expand our global leadership position as the premier network neutral data center operator for cloud and IT services providers, content providers, financial companies, enterprises and network services providers. Key components of our strategy include the following:

Improve customer performance through interconnection. We have assembled a critical mass of premier network providers and content companies and have become one of the core hubs of

the information-driven world. This critical mass is a key selling point for companies that want to connect with a diverse set of networks to provide the best connectivity to their end-customers and network companies that want to sell bandwidth to companies and interconnect with other networks in the most efficient manner available. Currently, we service more than 650 unique networks, including all of the top tier networks, allowing our customers to directly interconnect with providers that serve more than 90% of global Internet routes. We have a growing mass of key players in the cloud and IT services, enterprise and financial sectors, such as Bank of America, The GAP, Gannett Company, Inc., IBM, Salesforce.com, Sony and others. We expect that these segments will continue to grow as they seek to leverage our critical mass of network providers and interconnect directly with each other to improve performance.

Streamline ease of doing business globally. Data center reliability, power availability and network choice are the most important attributes considered by our customers when they are choosing a data center provider in a particular location. We have long been recognized as a leader in these areas and our performance continues to improve against these criteria. Our power infrastructure delivered 99.9999% uptime globally in 2010.

In 2010, more than half of our revenue came from customers with deployments across two or more of our global regions, and as globalization continues, seamless global services will become an increasingly important data center selection criteria. We are currently rolling out global product, pricing and contracts harmonization initiatives to meet these global demands.

Deepen existing and grow new ecosystems. As networks, cloud and IT services providers, content providers, financial services providers and other enterprises locate in our IBX data centers, it benefits their suppliers and business partners to do so as well to gain the full economic and performance benefits of direct interconnection for their business ecosystems. These partners, in turn, pull in their business partners, creating a “network effect” of customer adoption. Our interconnection services enable scalable, reliable and cost-effective interconnection and optimized traffic exchange thus lowering overall cost and increasing flexibility. The ability to directly interconnect with a wide variety of companies is a key differentiator for us in the market. We are rolling out innovative exchanges to accelerate commercial growth in our sites and accelerate this network effect.

Expand vertical go-to-market plan. We plan to continue to focus our go-to-market efforts on customer segments and business applications for whom our value proposition of reliability, global reach and ecosystem collaboration opportunities is particularly attractive. Today we have identified these segments as cloud and IT services, content and digital media, financial services, enterprises and network service providers. As digital business evolves, we will continue to identify and focus our go-to-market efforts on industry segments that need our value proposition.

Accelerate global reach and scale. We continue to evaluate expansion opportunities in select markets based on customer demand. We expect to open eight new IBX data centers, or IBX data center expansions, in eight markets in 2011. In April 2010, we successfully completed our acquisition of Switch and Data Facilities Company, Inc. (“Switch and Data”). This extended our presence into 16 new markets in the U.S. and Canada. In April 2011, we expanded into South America by investing with Riverwood Capital L.P. to acquire a controlling interest in ALOG Data Centers do Brasil S.A.

Our strategy is to continue to grow in select existing markets and possibly expand to additional markets where demand and financial return potential warrant. We expect to execute this expansion strategy in a cost-effective and disciplined manner through a combination of

Any investment in the notes involves a high degree of risk. You should consider the risks described below carefully and all of the information contained and incorporated by reference in this prospectus before deciding whether to purchase the notes. The risks and uncertainties described below are not the only risks and uncertainties we face. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also impair our business operations. If any of the events described in the following risks actually occur, our business, financial condition and results of operations could suffer. In that event, the price of the notes could decline, and you may lose all or part of your investment in the notes. The risks discussed below also include forward-looking statements and our actual results may differ substantially from those discussed in these forward-looking statements. See “Forward-Looking Statements.”

Acquisitions present many risks, and we may not realize the financial or strategic goals that were contemplated at the time of any transaction.

Over the last several years, we have completed several acquisitions, including that of Switch and Data Facilities Company, Inc. in 2010. We also acquired, with RW Brasil Fundo de Investimento em Participações, a subsidiary of Riverwood Capital L.P., approximately 90% of the outstanding capital stock of ALOG Data Centers do Brasil S.A. in 2011. We may make additional acquisitions in the future, which may include acquisitions of businesses, products, services or technologies that we believe to be complementary, acquisitions of new IBX data centers or real estate for development of new IBX data centers or through investments in local data center operators. We may pay for future acquisitions by using our existing cash resources (which may limit other potential uses of our cash), incurring additional debt (which may increase our interest expense, leverage and debt service requirements) and/or issuing shares (which may dilute our existing stockholders and have a negative effect on our earnings per share). Acquisitions expose us to several potential risks, including:

The occurrence of any of these risks could have a material adverse effect on our business, results of operations, financial condition or cash flows.

We cannot assure you that the price of any future acquisitions of IBX data centers will be similar to prior IBX data center acquisitions. In fact, we expect costs required to build or render new IBX data centers operational to increase in the future. If our revenue does not keep pace with these potential acquisition and expansion costs, we may not be able to maintain our current or expected margins as we absorb these additional expenses. There is no assurance we would successfully overcome these risks or any other problems encountered with these acquisitions.

Our substantial debt could adversely affect our cash flows and limit our flexibility to raise additional capital.

We have a significant amount of debt and expect to incur additional debt to support our growth. As of March 31, 2011, our total indebtedness was approximately $2.1 billion, our stockholders’ equity was $2.0 billion and our cash and investments totaled $456.7 million. On a pro forma basis, after giving effect to the issuance and sale of the notes offered hereby, our total consolidated indebtedness as of March 31, 2011 would have been $2.6 billion.

Our substantial amount of debt could have important consequences. For example, it could:

The occurrence of any of the foregoing factors could have a material adverse effect on our business, results of operations and financial condition. In addition, the performance of our stock price may trigger events that would require the write-off of a significant portion of our debt issuance costs related to our convertible debt, which may have a material adverse effect on our results of operations.

We may also need to refinance a portion of our outstanding debt as it matures, such as our $250.0 million 2.50% convertible subordinated notes due in 2012. There is a risk that we may not be able to refinance existing debt or that the terms of any refinancing may not be as favorable as the terms of our existing debt. Furthermore, if prevailing interest rates or other factors at the time of refinancing result in higher interest rates upon refinancing, then the interest expense relating to that refinanced indebtedness would increase. These risks could materially adversely affect our financial condition, cash flows and results of operations.

The uncertain economic environment may continue to have an impact on our business and financial condition.

The uncertain economic environment could have an adverse effect on our liquidity. Customer collections are our primary source of cash. While we believe we have a strong customer base and have continued to experience strong collections, if the current market conditions were to worsen, some of our customers may have difficulty paying us. As a result, we may experience increased churn in our customer base, including reductions in their commitments to us. We may also be required to further increase our allowance for doubtful accounts, which would negatively impact our results. Our sales cycle could also be further lengthened if customers slow spending, or delay decision-making, on our products and services, which could adversely affect our revenue growth. In addition, we could experience pricing pressure as a result of economic conditions if our competitors lower prices and attempt to lure away our customers with lower cost solutions.

The uncertain economic environment could also have an impact on our foreign exchange forward contracts if our counterparties’ credit deteriorates further or they are otherwise unable to perform their obligations.

Finally, our ability to access the capital markets may be severely restricted at a time when we would like, or need, to do so which could have an impact on our flexibility to pursue additional expansion opportunities and maintain our desired level of revenue growth in the future.

If we are not able to generate sufficient operating cash flows or obtain external financing, our ability to fund incremental expansion plans may be limited.

Our capital expenditures, together with ongoing operating expenses and obligations to service our debt, will be a substantial drain on our cash flow and may decrease our cash balances. Additional debt or equity financing may not be available when needed or, if available, may not be available on satisfactory terms. Our inability to obtain additional debt and/or equity financing or to generate sufficient cash from operations may require us to prioritize projects or curtail capital expenditures which could adversely affect our results of operations.

Fluctuations in foreign currency exchange rates in the markets in which we operate internationally could harm our results of operations.

We may experience gains and losses resulting from fluctuations in foreign currency exchange rates. To date, the majority of our revenues and costs are denominated in U.S. dollars; however, the majority of revenues and costs in our international operations are denominated in foreign currencies. Where our prices are denominated in U.S. dollars, our sales could be adversely affected by declines in foreign currencies relative to the U.S. dollar, thereby making our products and services more expensive in local currencies. We are also exposed to risks resulting from fluctuations in foreign currency exchange rates in connection with our international expansions. To the extent we are paying contractors in foreign currencies, our expansions could cost more than anticipated as a result of declines in the U.S dollar relative to foreign currencies. In addition, fluctuating foreign currency exchange rates have a direct impact on how our international results of operations translate into U.S. dollars.

Although we have in the past, and may decide in the future, to undertake foreign exchange hedging transactions to reduce foreign currency transaction exposure, we do not currently intend to eliminate all foreign currency transaction exposure. For example, while we hedge certain of our foreign currency assets and liabilities on our consolidated balance sheet, we do not hedge revenue. Therefore, any weakness of the U.S. dollar may have a positive impact on our consolidated results of operations because the currencies in the foreign countries in which we operate may translate into more U.S. dollars. However, if the U.S. dollar strengthens relative to the currencies of the foreign countries in which we operate our consolidated financial position and results of operations may be negatively impacted as amounts in foreign currencies will generally translate into fewer U.S. dollars. For additional information on foreign currency risk, refer to our discussion of foreign currency risk in “Quantitative and Qualitative Disclosures About Market Risk” in Part I, Item 3 of the Q1 2011 Report, which is incorporated by reference in this prospectus.

We are continuing to invest in our expansion efforts but may not have sufficient customer demand in the future to realize expected returns on these investments.

We are considering the acquisition or lease of additional properties and the construction of new IBX data centers beyond those expansion projects already announced. We will be required to commit substantial operational and financial resources to these IBX data centers, generally 12 to 18 months in advance of securing customer contracts, and we may not have sufficient customer demand in those markets to support these centers once they are built. In addition, unanticipated technological changes could affect customer requirements for data centers, and we may not have built such requirements into our new IBX data centers. Either of these contingencies, if they were to occur, could make it difficult for us to realize expected or reasonable returns on these investments.

Our products and services have a long sales cycle that may harm our revenues and operating results.

A customer’s decision to license cabinet space in one of our IBX data centers and to purchase additional services typically involves a significant commitment of resources. In addition, some customers will be reluctant to commit to locating in our IBX data centers until they are confident that the IBX data center has adequate carrier connections. As a result, we have a long sales cycle. Furthermore, we may expend significant time and resources in pursuing a particular sale or customer that does not result in revenue. We are also planning significant hiring in our sales force for 2011. It will take time for these new hires to become fully productive.

The current economic downturn may further impact this long sales cycle by making it extremely difficult for customers to accurately forecast and plan future business activities. This could cause customers to slow spending, or delay decision-making, on our products and services, which would delay and lengthen our sales cycle.

Delays due to the length of our sales cycle may materially and adversely affect our revenues and operating results, which could harm our ability to meet our forecasts for a given quarter and cause volatility in our stock price.

We have incurred substantial losses in the past and may incur additional losses in the future.

As of March 31, 2011, our accumulated deficit was $324.0 million. Although we have generated net income for each fiscal year since 2008, which was our first full year of net income since our inception, we are also currently investing heavily in our future growth through the build-out of multiple additional IBX data centers and IBX data center expansions as well as acquisitions of complementary businesses. As a result, we will incur higher depreciation and other operating expenses, as well as acquisition costs and interest expense, that may negatively impact our ability to sustain profitability in future periods unless and until these new IBX data centers generate enough revenue to exceed their operating costs and cover our additional overhead needed to scale our business for this anticipated growth. The current global financial crisis may also impact our ability to sustain profitability if we cannot generate sufficient revenue to offset the increased costs of our recently-opened IBX data centers or IBX data centers currently under construction. In addition, costs associated with the acquisition and integration of any acquired companies, as well as the additional interest expense associated with debt financing we have undertaken to fund our growth initiatives, may also negatively impact our ability to sustain profitability. Finally, given the competitive and evolving nature of the industry in which we operate, we may not be able to sustain or increase profitability on a quarterly or annual basis.

Any failure of our physical infrastructure or services could lead to significant costs and disruptions that could reduce our revenue and harm our business reputation and financial results.

Our business depends on providing customers with highly reliable service. We must protect our customers’ IBX infrastructure and their equipment located in our IBX data centers. While we own certain of our IBX data centers, others are leased by us, and we rely on the landlord for basic maintenance of the property. If such landlord has not maintained a leased property sufficiently, we may be forced into an early exit from the center which could be disruptive to our business. Furthermore, we continue to acquire IBX data centers not built by us. If we discover that these IBX data centers and their infrastructure assets are not in the condition we expected when they were acquired, we may be required to incur substantial additional costs to repair or upgrade the centers.

The services we provide in each of our IBX data centers are subject to failure resulting from numerous factors, including:

Problems at one or more of our IBX data centers, whether or not within our control, could result in service interruptions or significant equipment damage. We have service level commitment obligations to certain of our customers, including our significant customers. As a result, service interruptions or significant equipment damage in our IBX data centers could result in difficulty maintaining service level commitments to these customers and potential claims related to such failures. Because our IBX data centers are critical to many of our customers’ businesses, service interruptions or significant equipment damage in our IBX data centers could also result in lost profits or other indirect or consequential damages to our customers. We cannot guarantee that a court would enforce any contractual limitations on our liability in the event that one of our customers brings a lawsuit against us as a result of a problem at one of our IBX data centers.

We may incur significant liabilities to our customers in connection with a loss of power or our failure to meet other service level commitment obligations, or if we are held liable for a substantial damage award. In addition, any loss of service, equipment damage or inability to meet our service level commitment obligations could reduce the confidence of our customers and could consequently impair our ability to obtain and retain customers, which would adversely affect both our ability to generate revenues and our operating results.

We may also incur significant liability in the event of an earthquake, particularly in one of the high hazard zones for earth movement which include, but are not limited to, California, Japan, the New Madrid Seismic Zone and the Pacific Northwest Seismic Zone, where insurance coverage for earthquakes can be extremely expensive. While we purchase minimal levels of earthquake coverage for certain of our IBX data centers in California, at other California IBX data centers and in other high hazard zones we have elected to self-insure. In the event of a large earthquake in any of these locations, we may find our insurance coverage to be inadequate to cover our damages, and our business, financial condition and results of operations could be materially and adversely impacted.

The shortage of electricity supply and other aftermath caused by the recent Japanese earthquake and resulting tsunami may affect our business operations. We have two IBX centers close to Tokyo, Japan, one in Heiwajima and one in Shinagawa plus a third data center under construction in Tokyo. As of the date of this offering, all of our Japanese centers are operational. However, there can be no assurances that future operations and revenue may not be seriously affected by, among other things, the potential of the shortage of electricity power supply in Japan as well as the potential of a nuclear reactor disaster occurring at a power plant within one hundred and forty miles of our IBX centers. These events may seriously damage our ability to conduct business in Japan or, in the worst case, cause operations to completely cease with our Japanese revenue suffering a material downturn.

Furthermore, we are dependent upon Internet service providers, telecommunications carriers and other website operators in the Americas region, Asia-Pacific region, EMEA and elsewhere,

some of which have experienced significant system failures and electrical outages in the past. Users of our services may in the future experience difficulties due to system failures unrelated to our systems and services. If for any reason, these providers fail to provide the required services, our business, financial condition and results of operations could be materially and adversely impacted.

Our construction of additional new IBX data centers, or IBX data center expansions, could involve significant risks to our business.

In order to sustain our growth in certain of our existing and new markets, we must either expand an existing data center, lease a new facility or acquire suitable land with or without structures to build new IBX data centers from the ground up. Expansions or new builds are currently underway, or being contemplated, in many of our markets. Any related construction requires us to carefully select and rely on the experience of one or more general contractors, designers and associated subcontractors during the design and construction process. Should a general contractor, designer or significant subcontractor experience financial or other problems during the design or construction process, we could experience significant delays, increased costs to complete the project and other negative impacts to our expected returns. Site selection is also a critical factor in our expansion plans, and there may not be suitable properties available in our markets with the necessary combination of high power capacity and fiber connectivity.

While we may prefer to locate new IBX data centers adjacent to our existing locations, we may be limited by the inventory and location of suitable properties, as well as by the need for adequate power and optical fiber to the site. In the event we decide to build new IBX data centers separate from our existing IBX data centers, we may provide services to interconnect these two centers. Should these services not provide the necessary reliability to sustain service, this could result in lower interconnection revenue and lower margins and could have a negative impact on customer retention over time.

We are subject to various federal, state, local and foreign environmental and health and safety laws and regulations, including those relating to the generation, storage, handling and disposal of hazardous substances and wastes. Certain of these laws and regulations also impose joint and several liability, without regard to fault, for investigation and cleanup costs on current and former owners and operators of real property and persons who have disposed of or released hazardous substances into the environment. Our operations involve the use of hazardous substances and materials such as petroleum fuel for emergency generators, as well as batteries, cleaning solutions and other materials. In addition, we lease, own or operate real property at which hazardous substances and regulated materials have been used in the past. At some of our locations, hazardous substances or regulated materials are known to be present in soil or groundwater and there may be additional unknown hazardous substances or regulated materials present at sites we own, operate or lease. At some of our locations, there are land use restrictions in place relating to earlier environmental cleanups that do not materially limit our use of the sites. To the extent any hazardous substances or any other substance or material must be cleaned up or removed from our property, we may be responsible under applicable laws, regulations or leases for the removal or cleanup of such substances or materials, the cost of which could be substantial.

In addition, we are subject to environmental, health and safety laws regulating air emissions, storm water management and other issues arising in our business. While these obligations do not normally impose material costs upon our operations, unexpected events, equipment malfunctions and human error, among other factors, can lead to violations of environmental laws, regulations

or permits. Furthermore, environmental laws and regulations change frequently and may require additional investment to maintain compliance. Noncompliance with existing, or adoption of more stringent, environmental or health and safety laws and regulations or the discovery of previously unknown contamination could require us to incur costs or become the basis of new or increased liabilities that could be material.

Fossil fuel combustion creates greenhouse gas emissions that are linked to global climate change. Regulations to limit greenhouse gas emissions are in force in the European Union in an effort to prevent or reduce climate change. In the United States, federal legislative proposals have been considered that would, if adopted, implement some form of regulation or taxation to reduce or mitigate greenhouse gas (“GHG”) emissions. In addition, the U.S. Environmental Protection Agency (“EPA”) is taking steps towards using its existing authority under the Clean Air Act to regulate GHG emissions. On June 3, 2010, EPA published a final rule, known as the Tailoring Rule, setting forth the permitting program for regulating GHG emissions from major stationary sources. These permitting requirements will include, but are not limited to, meeting the best available control technologies for GHG emissions, and monitoring, reporting and recordkeeping for GHG emissions. The first steps of the program became effective January 2, 2011, and apply to large sources of GHGs such as, for example, fossil-fueled electricity generating facilities, that are already subject to Clean Air Act major source permits for their emission of non-greenhouse gas air pollutants (such as sulfur dioxide or particulate matter). The second step of the permitting program is effective July 1, 2011, and applies to the construction a new facility that will emit 100,000 tons per year or more of carbon dioxide equivalent (“CO2e”, a unit of measurement for GHGs) or to the modification of an existing facility that results in an increase of GHG emissions by 75,000 tons per year of CO2e. There is a small-source exception to the Tailoring Rule that we believe applies to our facilities. Under the exception, no source with emissions below 50,000 tons per year of CO2e or any modification resulting in an increase of less than 50,000 tons per year of CO2e will be subject to Prevention of Significant Deterioration (“PSD”) or Title V permitting before at least April 30, 2016. EPA also announced plans in the final rule to develop permitting requirements for smaller sources of GHGs after the expiration of the small-source exception, which could potentially affect our facilities. We will continue to monitor the developments of this regulatory program to evaluate its impact on our facilities and business.

If we are unable to recruit or retain qualified personnel, our business could be harmed.

We must continue to identify, hire, train and retain IT professionals, technical engineers, operations employees, and sales and senior management personnel who maintain relationships with our clients and who can provide the technical, strategic and marketing skills required for our company to grow. There is a shortage of qualified personnel in these fields, and we compete with other companies for the limited pool of these personnel. The failure to recruit and retain necessary technical, managerial, sales and marketing personnel, including but not limited to members of our executive team, could harm our business and our ability to grow our company.

We may not be able to compete successfully against current and future competitors.

Our IBX data centers and other products and services must be able to differentiate themselves from those of other providers of space and services for telecommunications companies, webhosting companies and other colocation providers. In addition to competing with neutral colocation providers, we must compete with traditional colocation providers, including telecom companies, carriers, Internet service providers and webhosting facilities. Similarly, with respect to our other products and services, including managed services, bandwidth services and security services, we must compete with more established providers of similar services. Most of these companies have longer operating histories and significantly greater financial, technical, marketing and other resources than us.

Because of their greater financial resources, some of our competitors have the ability to adopt aggressive pricing policies, especially if they are not highly leveraged. As a result, in the future, we may suffer from pricing pressure that would adversely affect our ability to generate revenues and adversely affect our operating results. In addition, these competitors could offer colocation on neutral terms, and may start doing so in the same metropolitan areas in which we have IBX data centers. Some of these competitors may also provide our target customers with additional benefits, including bundled communication services, and may do so in a manner that is more attractive to our potential customers than obtaining space in our IBX data centers. If these competitors were able to adopt aggressive pricing policies together with offering colocation space, our ability to generate revenues may be materially and adversely affected.

We may also face competition from persons seeking to replicate our IBX data center concept by building new data centers or converting existing data centers that some of our competitors are in the process of divesting. We may continue to see increased competition for data center space and customers from large REITS who also operate in our market. We may experience competition from our landlords, some of which are REITS, in this regard. Rather than leasing available space in our buildings to large single tenants, they may decide to convert the space instead to smaller square foot units designed for multi-tenant colocation use. Landlords/REITS may enjoy a cost effective advantage in providing services similar to those provided by our IBX data centers, and in addition to the risk of losing customers to these parties, this could also reduce the amount of space available to us for expansion in the future. Competitors may operate more successfully or form alliances to acquire significant market share. Furthermore, enterprises that have already invested substantial resources in outsourcing arrangements may be reluctant or slow to replace, limit or compete with their existing systems by becoming a customer. Customers may also decide it is cost-effective for them to build out their own data centers, which could have a negative impact on our results of operations. In addition, other companies may be able to attract the same potential customers that we are targeting. Once customers are located in competitors’ facilities, it may be extremely difficult to convince them to relocate to our IBX data centers.

Our business could be harmed by prolonged electrical power outages or shortages, increased costs of energy or general lack of availability of electrical resources.

Our IBX data centers are susceptible to regional costs of power, electrical power shortages, planned or unplanned power outages and limitations, especially internationally, on the availability of adequate power resources.

Power outages, such as those that occurred in California during 2001, the Northeast in 2003, from the tornados on the U.S. east coast in 2004, and relating to the earthquake and tsunami in Japan in 2011, could harm our customers and our business. We attempt to limit exposure to system downtime by using backup generators and power supplies; however, we may not be able to limit our exposure entirely even with these protections in place, as was the case with the power outages we experienced in our Chicago and Washington, D.C. metro area IBX data centers in 2005, London metro area IBX data centers in 2007 and Paris metro area IBX data centers in 2009.

In addition, global fluctuations in the price of power can increase the cost of energy, and although contractual price increase clauses exist in the majority of our customer agreements, we may not always choose to pass these increased costs on to our customers.

In each of our markets, we rely on third parties to provide a sufficient amount of power for current and future customers. At the same time, power and cooling requirements are growing on a per unit basis. As a result, some customers are consuming an increasing amount of power per cabinet. We generally do not control the amount of electric power our customers draw from

their installed circuits. This means that we could face power limitations in our centers. This could have a negative impact on the effective available capacity of a given center and limit our ability to grow our business, which could have a negative impact on our financial performance, operating results and cash flows.

We may also have difficulty obtaining sufficient power capacity for potential expansion sites in new or existing markets. We may experience significant delays and substantial increased costs demanded by the utilities to provide the level of electrical service required by our current IBX data center designs.

We are exposed to potential risks from errors in our financial reporting systems and controls, including the potential for material misstatements in our consolidated financial statements.

Section 404 of the Sarbanes-Oxley Act of 2002 requires companies to evaluate their internal controls over financial reporting. Although we received an unqualified opinion regarding the effectiveness of our internal control over financial reporting as of December 31, 2010, in the course of our ongoing evaluation we have identified certain areas where we would like to improve and we are in the process of evaluating and designing enhanced processes and controls to address such areas, none of which we believe constitutes a material change. However, we cannot be certain that our efforts will be effective or sufficient for us, or our independent registered public accounting firm, to issue unqualified reports in the future, especially as our business continues to grow and evolve and as we acquire other businesses.

Our ability to manage our operations and growth will require us to improve our operational, financial and management controls, as well as our internal reporting systems and controls. We may not be able to implement improvements to our internal reporting systems and controls in an efficient and timely manner and have in the past, and may in the future, discover deficiencies in existing systems and controls. In addition, internal reporting systems and controls are subject to human error. Any such deficiencies could result in material misstatements in our consolidated financial statements, which might involve restating previously issued financial statements. Additionally, as we expand, we will need to implement new systems to support our financial reporting systems and controls. We may not be able to implement these systems such that errors would be identified in a timely manner, which could result in material misstatements in our consolidated financial statements.

If we cannot effectively manage our international operations, and successfully implement our international expansion plans, our revenues may not increase and our business and results of operations would be harmed.

For the years ended December 31, 2010, 2009 and 2008, we recognized 38%, 39% and 37%, respectively, of our revenues outside the U.S. For the three months ended March 31, 2011, we recognized 36% of our revenues outside the U.S. We currently operate outside of the Americas in the EMEA and Asia-Pacific regions. In April 2011, we expanded into South America through an investment in ALOG Data Centers do Brasil S.A.

To date, the network neutrality of our IBX data centers and the variety of networks available to our customers has often been a competitive advantage for us. In certain of our acquired IBX data centers in the Asia-Pacific region the limited number of carriers available reduces that advantage. As a result, we may need to adapt our key revenue-generating services and pricing to be competitive in those markets. In addition, we are currently undergoing expansions or evaluating expansion opportunities in the EMEA and Asia-Pacific regions. Undertaking and managing expansions in foreign jurisdictions may present unanticipated challenges to us.

Our international operations are generally subject to a number of additional risks, including:

In addition, compliance with international and U.S. laws and regulations that apply to our international operations increases our cost of doing business in foreign jurisdictions. These laws and regulations include data privacy requirements, labor relations laws, tax laws, anti-competition regulations, import and trade restrictions, export requirements, U.S. laws such as the Foreign Corrupt Practices Act, and local laws which also prohibit corrupt payments to governmental officials. Violations of these laws and regulations could result in fines, criminal sanctions against us, our officers or our employees, and prohibitions on the conduct of our business. Any such violations could include prohibitions on our ability to offer our services in one or more countries, could delay or prevent potential acquisitions, and could also materially damage our reputation, our brand, our international expansion efforts, our ability to attract and retain employees, our business and our operating results. Our success depends, in part, on our ability to anticipate and address these risks and manage these difficulties.

Economic uncertainty in developing markets could adversely affect our revenue and earnings.

We conduct business and plan to expand in developing markets with economies that tend to be more volatile than those in the United States and Western Europe. The risk of doing business in developing markets such as China, Brazil, United Arab Emirates and other economically volatile areas could adversely affect our operations and earnings. Such risks include the financial instability among customers in these regions, political instability, fraud or corruption and other non-economic factors such as irregular trade flows that need to be managed successfully with the help of the local governments. In addition, commercial laws in some developing countries can be vague, inconsistently administered and retroactively applied. If we are deemed not to be in compliance with applicable laws in developing countries where we conduct business, our

prospects and business in those countries could be harmed, which could then have a material adverse impact on our results of operations and financial position. Our failure to successfully manage economic, political and other risks relating to doing business in developing countries and economically and politically volatile areas could adversely affect our business.

The increased use of high power density equipment may limit our ability to fully utilize our IBX data centers.

Customers are increasing their use of high-density electrical power equipment, such as blade servers, in our IBX data centers which has significantly increased the demand for power on a per cabinet basis. Because many of our IBX data centers were built a number of years ago, the current demand for electrical power may exceed the designed electrical capacity in these centers. As electrical power, not space, is a limiting factor in many of our IBX data centers, our ability to fully utilize those IBX data centers may be limited. The availability of sufficient power may also pose a risk to the successful operation of our new IBX data centers. The ability to increase the power capacity of an IBX data center, should we decide to, is dependent on several factors including, but not limited to, the local utility’s ability to provide additional power; the length of time required to provide such power; and/or whether it is feasible to upgrade the electrical infrastructure of an IBX data center to deliver additional power to customers. Although we are currently designing and building to a much higher power specification, there is a risk that demand will continue to increase and our IBX data centers could become obsolete sooner than expected.

We have experienced fluctuations in our results of operations on a quarterly and annual basis. The fluctuations in our operating results may cause the market price of our common stock to be volatile. We may experience significant fluctuations in our operating results in the foreseeable future due to a variety of factors, including, but not limited to:

Any of the foregoing factors, or other factors discussed elsewhere in this report, could have a material adverse effect on our business, results of operations and financial condition. Although we have experienced growth in revenues in recent quarters, this growth rate is not necessarily indicative of future operating results. Prior to 2008, we had generated net losses every fiscal year since inception. It is possible that we may not be able to generate net income on a quarterly or annual basis in the future. In addition, a relatively large portion of our expenses are fixed in the short-term, particularly with respect to lease and personnel expenses, depreciation and amortization and interest expenses. Therefore, our results of operations are particularly sensitive to fluctuations in revenues. As such, comparisons to prior reporting periods should not be relied upon as indications of our future performance. In addition, our operating results in one or more future quarters may fail to meet the expectations of securities analysts or investors.

The failure to obtain favorable terms when we renew our IBX data center leases could harm our business and results of operations.

While we own certain of our IBX data centers, others are leased under long-term arrangements with lease terms expiring at various dates ranging from 2011 to 2035. These leased centers have all been subject to significant development by us in order to convert them from, in most cases, vacant buildings or warehouses into IBX data centers. Most of our IBX data center leases have renewal options available to us. However, many of these renewal options provide for rent set at then-prevailing market rates. To the extent that then-prevailing market rates are higher than present rates, these higher costs may adversely impact our business and results of operations.

We depend on a number of third parties to provide Internet connectivity to our IBX data centers; if connectivity is interrupted or terminated, our operating results and cash flow could be materially and adversely affected.

The presence of diverse telecommunications carriers’ fiber networks in our IBX data centers is critical to our ability to retain and attract new customers. We are not a telecommunications carrier, and as such we rely on third parties to provide our customers with carrier services. We believe that the availability of carrier capacity will directly affect our ability to achieve our projected results. We rely primarily on revenue opportunities from the telecommunications carriers’ customers to encourage them to invest the capital and operating resources required to connect from their centers to our IBX data centers. Carriers will likely evaluate the revenue opportunity of an IBX data center based on the assumption that the environment will be highly competitive. We cannot provide assurance that each and every carrier will elect to offer its services within our IBX data centers or that once a carrier has decided to provide Internet connectivity to our IBX data centers that it will continue to do so for any period of time.

Our new IBX data centers require construction and operation of a sophisticated redundant fiber network. The construction required to connect multiple carrier facilities to our IBX data centers is complex and involves factors outside of our control, including regulatory processes and the availability of construction resources. Any hardware or fiber failures on this network may result in significant loss of connectivity to our new IBX data center expansions. This could affect our ability to attract new customers to these IBX data centers or retain existing customers.

If the establishment of highly diverse Internet connectivity to our IBX data centers does not occur, is materially delayed or is discontinued, or is subject to failure, our operating results and cash flow will be adversely affected.

We may be vulnerable to security breaches which could disrupt our operations and have a material adverse effect on our financial performance and operating results.

A party who is able to compromise the security measures on our networks or the security of our infrastructure could misappropriate either our proprietary information or the personal information of our customers, or cause interruptions or malfunctions in our operations. We may be required to expend significant capital and resources to protect against such threats or to alleviate problems caused by breaches in security. As techniques used to breach security change frequently, and are generally not recognized until launched against a target, we may not be able to implement security measures in a timely manner or, if and when implemented, we may not be able to determine the extent to which these measures could be circumvented. Any breaches that may occur could expose us to increased risk of lawsuits, regulatory penalties, loss of existing or potential customers, harm to our reputation and increases in our security costs, which could have a material adverse effect on our financial performance and operating results.

We have government customers, which subjects us to risks including early termination, audits, investigations, sanctions and penalties.

We derive some revenues from contracts with the U.S. government, state and local governments and their respective agencies. Some of these customers may terminate all or part of their contracts at any time, without cause.

There is increased pressure for governments and their agencies, both domestically and internationally, to reduce spending. Some of our federal government contracts are subject to the approval of appropriations being made by the U.S. Congress to fund the expenditures under these contracts. Similarly, some of our contracts at the state and local levels are subject to government funding authorizations.

Additionally, government contracts are generally subject to audits and investigations which could result in various civil and criminal penalties and administrative sanctions, including termination of contracts, refund of a portion of fees received, forfeiture of profits, suspension of payments, fines and suspensions or debarment from future government business.

Because we depend on the development and growth of a balanced customer base, including key magnet customers, failure to attract, grow and retain this base of customers could harm our business and operating results.

Our ability to maximize revenues depends on our ability to develop and grow a balanced customer base, consisting of a variety of companies, including enterprises, cloud, digital content and financial companies, and network service providers. We consider certain of these customers to be key magnets in that they draw in other customers. The more balanced the customer base within each IBX data center, the better we will be able to generate significant interconnection revenues, which in turn increases our overall revenues. Our ability to attract customers to our IBX data centers will depend on a variety of factors, including the presence of multiple carriers, the mix of products and services offered by us, the overall mix of customers, the presence of key customers attracting business through vertical market ecosystems, the IBX data center’s operating reliability and security and our ability to effectively market our services. However, some of our customers may face competitive pressures and may ultimately not be successful or may be consolidated through merger or acquisition. If these customers do not continue to use our IBX data centers it may be disruptive to our business. Finally, the uncertain economic climate may harm our ability to attract and retain customers if customers slow spending, or delay decision-making, on our products and services, or if customers begin to have difficulty paying us and we experience increased churn in our customer base. Any of these factors may hinder the development, growth and retention of a balanced customer base and adversely affect our business, financial condition and results of operations.

We are subject to securities class action and other litigation, which may harm our business and results of operations.

We are subject to various legal proceedings as described in Note 9 to Notes to Consolidated Financial Statements in the Q1 2011 Report. In addition, we may, in the future, be subject to other litigation. For example, securities class action litigation has often been brought against a company following periods of volatility in the market price of its securities. Litigation can be lengthy, expensive, and divert management’s attention and resources. Results cannot be predicted with certainty and an adverse outcome in litigation could result in monetary damages or injunctive relief that could seriously harm our business, results of operations, financial condition or cash flows.

We cannot assure that the steps taken by us to protect our intellectual property rights will be adequate to deter misappropriation of proprietary information or that we will be able to detect unauthorized use and take appropriate steps to enforce our intellectual property rights. We also are subject to the risk of litigation alleging infringement of third-party intellectual property rights. Any such claims could require us to spend significant sums in litigation, pay damages, develop non-infringing intellectual property, or acquire licenses to the intellectual property that is the subject of the alleged infringement.

Various laws and governmental regulations, both in the U.S. and abroad, governing Internet related services, related communications services and information technologies remain largely unsettled, even in areas where there has been some legislative action. For example, the Federal Communications Commission recently issued a Notice of Inquiry for comments on proposed Internet rules and regulation of broadband that may result in material changes in the regulations and contribution regime affecting us and our customers. Likewise, as part of a review of the current equity market structure, the Securities and Exchange Commission and the Commodity Futures Trading Commission have both sought comments regarding the regulation of independent data centers, such as Equinix, which provide colocation services for financial markets and exchanges. Such regulation may ultimately affect our provision of services.

It also may take years to determine whether and how existing laws, such as those governing intellectual property, privacy, libel, telecommunications services and taxation, apply to the Internet and to related services such as ours and substantial resources may be required to comply with regulations or bring any non-compliant business practices into compliance with such regulations. In addition, the development of the market for online commerce and the displacement of traditional telephony service by the Internet and related communications services may prompt an increased call for more stringent consumer protection laws or other regulation both in the U.S. and abroad that may impose additional burdens on companies conducting business online and their service providers.

The adoption, or modification of laws or regulations relating to the Internet and our business, or interpretations of existing laws, could have a material adverse effect on our business, financial condition and results of operations.

The telecommunications industry is currently undergoing consolidation. As customers combine businesses, they may require less colocation space, and there may be fewer networks available to choose from. Given the competitive and evolving nature of this industry, further consolidation of our customers and/or our competitors may present a risk to our network-neutral business model and have a negative impact on our revenues and results of operations. In addition, increased utilization levels industry-wide could lead to a reduced amount of attractive expansion opportunities available to us.

Terrorist activity throughout the world and military action to counter terrorism could adversely impact our business.

The continued threat of terrorist activity and other acts of war or hostility contribute to a climate of political and economic uncertainty. Due to existing or developing circumstances, we may need to incur additional costs in the future to provide enhanced security, including cybersecurity, which would have a material adverse effect on our business and results of operations. These

circumstances may also adversely affect our ability to attract and retain customers, our ability to raise capital and the operation and maintenance of our IBX data centers. We may not have adequate property and liability insurance to cover catastrophic events or attacks.

Certain provisions of our certificate of incorporation and bylaws may discourage, delay or prevent a third party from acquiring control of us in a merger, acquisition or similar transaction that a stockholder may consider favorable. Such provisions include:

In addition, Section 203 of the Delaware General Corporation Law, which restricts certain business combinations with interested stockholders in certain situations, may also discourage, delay or prevent someone from acquiring or merging with us.

References to “Equinix,” the “Company,” “we,” “our” and “us” and similar terms in this section “Risk Factors—Risks Relating to the Notes” mean Equinix, Inc. and not any of its subsidiaries.

Our subsidiaries will not guarantee the notes. We depend in large part on the cash flow from our subsidiaries to meet our obligations, and your claims will be subordinated to all of the creditors of these subsidiaries.

Our subsidiaries will not guarantee the notes. Our subsidiaries are separate and distinct legal entities with no obligation to pay any amounts due pursuant to the notes or to provide us with funds for our payment obligations. Substantially all of our operations are conducted through our subsidiaries and we derive substantially all our revenues from our subsidiaries, and substantially all of our operating assets are owned by our subsidiaries. As a result, our cash flow and our ability to service our indebtedness, including the notes, depends in large part on the earnings of our subsidiaries and on the distribution of earnings, loans or other payments to us by these subsidiaries. Payments to us by our subsidiaries also will be contingent upon their earnings and their business considerations. In addition, the ability of our subsidiaries to make any dividend, distribution, loan or other payment to us could be subject to statutory or contractual restrictions. Because we depend in large part on the cash flow of our subsidiaries to meet our obligations, these types of restrictions may impair our ability to make scheduled interest and principal payments on the notes. Our subsidiaries held approximately 81% of our consolidated assets as of March 31, 2011.

The notes will be unsecured and effectively subordinated to any of our secured indebtedness and structurally subordinated to all of the liabilities of our subsidiaries.

The notes will be our general unsecured senior obligations, ranking equal in right of payment with our existing and any future unsubordinated indebtedness. However, because they are unsecured, the notes will be effectively junior to any of our secured indebtedness to the

extent of the value of the assets securing such debt. As of March 31, 2011, after giving pro forma effect to the offering, we would have had total consolidated indebtedness of approximately $2.6 billion, none of which was secured indebtedness of Equinix.

In addition, the notes will be structurally subordinated to all of the liabilities of our subsidiaries, which may include indebtedness, trade payables, guarantees, lease obligations and letter of credit obligations. In the event of a bankruptcy, liquidation or reorganization of any of our subsidiaries, holders of their indebtedness and their trade creditors will generally be entitled to payment of their claims from the assets of those subsidiaries before any assets of the subsidiaries are made available for distribution to us. As of March 31, 2011, our subsidiaries had $937 million of indebtedness and other liabilities (including trade payables but excluding intercompany items and liabilities of a type not required to be reflected on a balance sheet of such subsidiaries in accordance with GAAP).

In addition, the indenture governing the notes will permit us and our subsidiaries to incur significant amounts of additional indebtedness, including secured indebtedness. In the event that we are declared bankrupt, become insolvent or liquidate or reorganize, our assets that serve as collateral under any such secured indebtedness would be made available to satisfy the obligations under the secured indebtedness before those assets may be used to satisfy our obligations with respect to the notes. Holders of the notes will participate ratably with all holders of our unsecured indebtedness that is deemed to be of the same class as the notes, and potentially with all of our other general creditors, based upon the respective amounts owed to each holder or creditor, in our remaining assets. In any of the foregoing events, we cannot assure you that there will be sufficient assets to pay amounts due on the notes. As a result, holders of the notes may receive less, ratably, than holders of secured indebtedness.

Our debt agreements allow us and our subsidiaries to incur significantly more debt, which could exacerbate the other risks described herein.

The terms of our debt instruments, including the indenture governing the notes offered hereby, permit us and our subsidiaries to incur additional indebtedness. Additional debt may be necessary for many reasons, including to adequately respond to competition, to comply with regulatory requirements related to our service obligations or for financial reasons alone. We are considering increasing amounts available to us for borrowing by entering into new term loans or revolving credit facilities. Incremental borrowings or borrowings at maturity on terms that impose additional financial risks to our various efforts to improve our operating results and financial condition could exacerbate the other risks described herein.

Our revolving credit line and other debt instruments have restrictive covenants that could limit our financial flexibility.

The indentures related to the notes, our 8.125% senior notes due 2018 and our revolving credit line contain financial and other restrictive covenants that limit our ability to engage in activities that may be in our long-term best interests. Our ability to borrow under our revolving credit line is subject to compliance with certain financial covenants, including leverage and interest coverage ratios. Our revolving credit line includes other restrictions that, among other things, limit our ability to incur indebtedness; grant liens; engage in mergers, consolidations and liquidations; make asset dispositions, restricted payments and investments; enter into transactions with affiliates; and amend, modify or prepay certain indebtedness. The indenture related to the notes will contain limitations on our ability to effect mergers and change of control events, as well as other limitations, including:

Our failure to comply with these covenants could result in an event of default that, if not cured or waived, could result in the acceleration of all of our debts. We do not have sufficient working capital to satisfy our debt obligations in the event of an acceleration of all or a significant portion of our outstanding indebtedness.

Upon the occurrence of a change of control (as defined in “Description of Notes—Change of Control”), we will be required to make an offer to purchase each holder’s notes at a purchase price equal to 101% of the principal amount thereof plus accrued and unpaid interest to, but not including, the date of repurchase.

If we experience a change of control, we may not have sufficient financial resources available to satisfy our obligations to repurchase the notes. Our failure to repurchase the notes as required under the indenture governing the notes would result in a default under the indenture, which could result in defaults under our and our subsidiaries’ other debt agreements and have material adverse consequences for us and the holders of the notes. See “Description of Notes—Change of Control.” Moreover, if holders of the notes elect to have their notes repurchased by us (or holders of our other existing and future debt securities such as our 8.125% Senior Notes due 2018 that have a similar right to require us to repurchase their securities upon such a change on control elect to have their debt securities repurchased by us) it could cause a default under our existing or future debt, even if the change of control itself does not result in a default under existing or future debt, due to the financial effect of such repurchase on us.

The terms of the indenture and the notes provide only limited protection against significant corporate events that could affect adversely your investment in the notes.

While the indenture and the notes contain terms intended to provide protection to holders upon the occurrence of certain events involving significant corporate transactions or our creditworthiness, these terms are limited and may not be sufficient to protect your investment in the notes. As described under “Description of the Notes — Change of Control,” upon the occurrence of a change of control, we will be required to make an offer to purchase each holder’s notes at a purchase price equal to 101% of the principal amount thereof plus accrued and unpaid interest to, but not including, the date of repurchase. However, the change of control provisions may not protect you if we undergo a highly leveraged transaction, reorganization, restructuring, acquisition or similar transaction that may negatively affect the value of your notes unless the transaction is included within the definition of a change of control. If we were to enter into a significant corporate transaction that would negatively affect the value of the notes, but that would not constitute a change of control triggering event, you would not have any rights to require us to repurchase the notes prior to their maturity, which also would adversely affect your investment.

An active trading market for the notes may not develop or be maintained; many factors affect the trading market and value of the notes.

The notes are a new issue of securities with no trading history or established trading market. We cannot assure you that a trading market for the notes will ever develop or, if a trading market develops, that it will be maintained or provide adequate liquidity, that holders will be able to sell any of the notes at a particular time (if at all) or that the prices holders receive if or when they sell the notes will be above their initial offering price. We have not applied, and do not intend to apply, for the listing of the notes on any automated dealer quotation system.

A real or perceived economic downturn or higher interest rates could cause a decline in the value of the notes, and to high-yield bonds generally, and thereby negatively impact the market for high-yield bonds, and more specifically, the notes. Because the notes may be thinly traded, it may be more difficult to sell and accurately value the notes. In addition, as has been evident in the recent volatility in the global financial markets, the present economic slowdown and the uncertainty over its breadth, depth and duration, the entire high-yield bond market can experience sudden and sharp price swings, which can be exacerbated by large or sustained sales by major investors in the notes, a high-profile default by another issuer, or simply a change in the market’s psychology regarding high-yield notes.

Our credit ratings may not reflect all of the risks of an investment in the notes.

The credit ratings on the notes may not reflect the potential impact of all of the risks related to structure and other factors on the value of the notes. In addition, actual or anticipated changes in our credit ratings will generally affect the market value of the notes.

We may invest or spend the net proceeds of this offering in ways with which you may not agree and in ways that may not earn a profit.

We intend to use the net proceeds of this offering for general corporate purposes, which may include capital expenditures, repayment of our 2.50% convertible subordinated notes due 2012 upon maturity, working capital and potential acquisitions and strategic transactions. From time to time we evaluate potential strategic transactions and acquisitions of businesses, technologies or products. Currently, we do not have any agreements or understandings with respect to any such material strategic transactions or acquisitions. However, we will retain broad discretion over the use of the net proceeds from this offering. You may not agree with the ways we decide to use these proceeds, and our use of the proceeds may not yield any profits.

If the notes are rated investment grade at any time by both Standard & Poor’s and Moody’s, most of the restrictive covenants contained in the indenture governing the notes will be suspended.

If, at any time, the credit rating on the notes, as determined by both Standard & Poor’s and Moody’s, equals or exceeds BBB- and Baa3, respectively, or any equivalent replacement ratings, we will not be subject to most of the restrictive covenants and certain events of default contained in the indenture governing the notes. As a result, you may have less credit protection than you will at the time the notes are issued. In the event that one or both of the ratings later drops below investment grade, we will thereafter again be subject to such restrictive covenants and events of default.

The following table sets forth our consolidated ratio of earnings to fixed charges:

In calculating the ratio of earnings to fixed charges, earnings consist of net income (loss) before income tax expense, cumulative effect of a change in accounting principle and fixed charges. Fixed charges consist of interest expense, including such portion of rental expense that was attributed to interest.

The following table sets forth our cash, cash equivalents and short-term and long-term investments and current portion of our indebtedness and our capitalization as of March 31, 2011:

This table should be read in conjunction with the section “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and our consolidated financial statements and related notes from the Q1 2011 Report incorporated by reference in this prospectus.

The Company will issue the notes under an indenture (the “Indenture”) between itself and U.S. Bank National Association, as Trustee (the “Trustee”). The following is a summary of the material provisions of the Indenture. The Indenture will comply with the Trust Indenture Act of 1939. The terms of the notes include those stated in the Indenture and those made part of the Indenture by reference to certain provisions of the Trust Indenture Act. You can find definitions of certain capitalized terms used in this description under “—Certain Definitions.” For purposes of this section, references to the “Company” include only Equinix, Inc. and not its subsidiaries. You are encouraged to read the Indenture because it, and not this description, defines your rights as a holder of the notes. Copies of the Indenture are available upon request to the Company at the address indicated under “Where You Can Find Additional Information” in this prospectus.

The Company will issue the notes in fully registered form in denominations of $2,000 and integral multiples of $1,000 in excess thereof. The Trustee will initially act as Paying Agent and Registrar for the notes. The notes may be presented for registration or transfer and exchange at the offices of the Registrar. The Company may change any Paying Agent and Registrar without notice to holders of the notes (the “Holders”). The Company will pay principal (and premium, if any) on the notes at the Trustee’s corporate office in New York, New York. At the Company’s option, interest may be paid at the Trustee’s corporate trust office or by check mailed to the registered address of Holders.

The Company is issuing $500.0 million aggregate principal amount of notes in this offering and, subject to compliance with the limitations described under “—Certain Covenants—Limitation on Incurrence of Additional Indebtedness,” may issue an unlimited principal amount of additional notes at later dates under the same Indenture (the “Additional Notes”). Any Additional Notes that the Company issues in the future will be identical in all respects to the notes that the Company is issuing now and will be treated as a single class for all purposes under the Indenture with the notes offered hereby, except that notes issued in the future will have different issuance dates and may have different issuance prices; provided that if any such Additional Notes are not fungible with the notes offered hereby for U.S. federal income tax purposes, such Additional Notes will have one or more separate CUSIP numbers. Unless the context requires otherwise, references to “notes” for all purposes of the Indenture and this “Description of Notes” include any Additional Notes that are actually issued.

Interest on the notes will accrue at a rate of % per annum and will be payable semi-annually in arrears on January 15 and July 15, commencing on January 15, 2012. The Company will pay interest to those persons who were holders of record on the January 1 or July 1 immediately preceding each interest payment date. Interest on the notes will accrue from the date of original issuance or, if interest has already been paid, from the date it was most recently paid. Interest will be computed on the basis of a 360-day year comprised of twelve 30-day months.

The notes will be general senior obligations of the Company. The Holders’ right to payment under these notes will be:

At March 31, 2011, after giving pro forma effect to the offering, the Company had total consolidated indebtedness of approximately $2.6 billion, none of which was secured indebtedness of Equinix. At such date, the Subsidiaries of the Company had approximately $937 million of indebtedness and other liabilities (including trade payables but excluding intercompany items and liabilities of a type not required to be reflected on a balance sheet of such Subsidiaries in accordance with GAAP).

At any time prior to July 15, 2014, the Company may on any one or more occasions redeem up to 35% of the aggregate principal amount of the notes (calculated giving effect to any issuance of Additional Notes) outstanding under the Indenture, at a redemption price equal to % of the principal amount of the notes to be redeemed, plus accrued and unpaid interest to, but not including, the redemption date, with the net cash proceeds of one or more Equity Offerings; provided that

(1) at least 65% of the aggregate principal amount of the notes (calculated giving effect to any issuance of Additional Notes) issued under the Indenture remains outstanding immediately after the occurrence of such redemption (excluding notes held by the Company and its subsidiaries); and

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

On or after July 15, 2016, the Company may redeem all or a part of the notes, on any one or more occasions, at the redemption prices (expressed as percentages of principal amount) set forth below plus accrued and unpaid interest thereon, if any, to, but not including, the applicable redemption date, if redeemed during the twelve-month period beginning on July 15 of the years indicated below:

At any time prior to July 15, 2016, the Company may also redeem all or a part of the notes at a redemption price equal to 100% of the principal amount of notes redeemed plus the Applicable Premium as of, and accrued and unpaid interest, if any, to, but not including, the date of redemption (the “Redemption Date”), subject to the rights of Holders of record of notes on the relevant record date to receive interest due on the relevant interest payment date.

In the event that the Company chooses to redeem less than all of the notes, selection of the notes for redemption will be made by the Trustee:

1. in compliance with the requirements of the principal national securities exchange, if any, on which the notes are listed; or

2. if the notes are not listed on a national securities exchange, on a pro rata basis, by lot or by such method as the Trustee shall deem fair and appropriate;

No notes of a principal amount of $2,000 or less shall be redeemed in part. Notice of redemption will be mailed by first-class mail at least 30 but not more than 60 days before the redemption date to each Holder of notes to be redeemed at its registered address. If any note is to be redeemed in part only, then the notice of redemption that relates to such note must state the portion of the principal amount thereof to be redeemed. A new note in a principal amount equal to the unredeemed portion thereof will be issued in the name of the Holder thereof upon cancellation of the original note (or appropriate adjustments to the amount and beneficial interests in a global note will be made). On and after the redemption date, interest will cease to accrue on notes or portions thereof called for redemption as long as the Company has deposited with the Paying Agent funds in satisfaction of the applicable redemption price.

We are not required to make any mandatory redemption or sinking fund payments with respect to the notes. However, under certain circumstances, we may be required to offer to purchase notes as described under “—Change of Control” and “—Certain Covenants—Limitation on Asset Sales.” We may at any time and from time to time purchase notes in the open market or otherwise, subject to compliance with applicable securities laws.

The Company is a holding company for its Subsidiaries. Substantially all of the Company’s operations are conducted through its Subsidiaries and the Company derives substantially all its revenues from its Subsidiaries, and substantially all of its operating assets are owned by its Subsidiaries. Accordingly, the Company is dependent upon the distribution of the earnings of its Subsidiaries, whether in the form of dividends, advances or payments on account of intercompany obligations, to service its debt obligations. In addition, the claims of the Holders are subject to the prior payment of all liabilities (whether or not for borrowed money) and to any preferred stock interest of such Restricted Subsidiaries. There can be no assurance that, after providing for all prior claims, there would be sufficient assets available from the Company and its Subsidiaries to satisfy the claims of the Holders of notes. See “Risk Factors—Our subsidiaries will not guarantee the notes. We depend in large part on the cash flow from our subsidiaries to meet our obligations, and your claims will be subordinated to all of the creditors of these subsidiaries.”

On the Issue Date, the notes will not be guaranteed by any of the Company’s Subsidiaries. To the extent that, in the future, any Domestic Restricted Subsidiary of the Company becomes a Guarantor pursuant to the “Subsidiary Guarantees” covenant, such Guarantor will unconditionally, jointly and severally guarantee the Company’s obligations under the Indenture and the notes on a senior unsecured basis. The obligations of each Guarantor under its Guarantee will be limited as necessary to prevent the Guarantee from constituting a fraudulent conveyance or fraudulent transfer under applicable law.

Upon the occurrence of a Change of Control, unless the Company or a third party has previously or concurrently mailed a redemption notice with respect to all outstanding notes as described under “—Redemption,” the Company will be required to make an offer to purchase each Holder’s notes pursuant to the offer described below (the “Change of Control Offer”), at a purchase price equal to 101% of the principal amount thereof plus accrued and unpaid interest to the date of purchase.

Within 30 days following the date upon which the Change of Control occurred, the Company must send, or cause the Trustee to send, by first class mail, a notice to each Holder, with a copy to the Trustee, which notice shall govern the terms of the Change of Control Offer. Such notice shall state, among other things, the purchase date, which must be no earlier than 30 days nor later than 60 days after the date such notice is mailed, other than as may be required by law (the “Change of Control Payment Date”). Holders electing to have a note purchased pursuant to a Change of Control Offer will be required to surrender the note, with the form entitled “Option of Holder to Elect Purchase” on the reverse of the note completed and specifying the portion (equal to $2,000 and integral multiples of $1,000 in excess thereof) of such Holder’s notes that it agrees to sell to the Company pursuant to the Change of Control Offer, to the Paying Agent at the address specified in the notice prior to the close of business on the third business day prior to the Change of Control Payment Date.

If a Change of Control Offer is made, there can be no assurance that the Company will have available funds sufficient to pay the purchase price for all the notes that might be delivered by Holders seeking to accept the Change of Control Offer. In the event the Company is required to purchase outstanding notes pursuant to a Change of Control Offer, the Company expects that it would seek third-party financing to the extent it does not have available funds to meet its purchase obligations. However, there can be no assurance that the Company would be able to obtain such financing. In addition, there can be no assurance that the Company would be able to obtain the consents necessary to consummate a Change of Control Offer from the lenders under agreements governing outstanding Indebtedness that may in the future prohibit the Change of Control Offer. The failure to consummate a Change of Control Offer would constitute an Event of Default under the Indenture. See “Risk Factors—We may not be able to repurchase the notes upon a change of control” for more information.

One of the events that constitutes a Change of Control under the Indenture is the disposition of “all or substantially all” of the Company’s assets. This term has not been interpreted under New York law, which is the governing law of the Indenture, to represent a specific quantitative test. As a consequence, if Holders of the notes assert that the Company is required to make a Change of Control Offer and the Company elects to contest such assertion, there is uncertainty as to how a court interpreting New York law would interpret the term. Neither the Board of Directors of the Company nor the Trustee may waive the covenant of the Company to make a Change of Control Offer following a Change of Control. Restrictions in the Indenture described

herein on the ability of the Company and its Subsidiaries to incur additional Indebtedness, to grant Liens on the property of the Company and the Restricted Subsidiaries and to make Restricted Payments may also make more difficult or discourage a takeover of the Company, whether favored or opposed by the management or stockholders of the Company. There can be no assurance that the Company or the acquiring party will have sufficient financial resources to effect a Change of Control Offer. Such restrictions may, in certain circumstances, make more difficult or discourage any leveraged buyout of the Company or any of its Subsidiaries by their respective management. However, the Indenture may not afford the Holders protection in all circumstances from the adverse aspects of a highly leveraged transaction, reorganization, amalgamation, restructuring, merger or similar transaction.

The Company will not be required to make a Change of Control Offer upon a Change of Control if a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in the Indenture applicable to a Change of Control Offer made by the Company and purchases all notes validly tendered and not withdrawn under such Change of Control Offer. The Company (or a third party) may make a Change of Control Offer in advance of, and conditioned upon, any Change of Control.

The Company will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent such laws and regulations are applicable in connection with the repurchase of notes pursuant to a Change of Control Offer. To the extent that the provisions of any securities laws or regulations conflict with the “Change of Control” provisions of the Indenture, the Company shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under the “Change of Control” provisions of the Indenture by virtue thereof.

During any period of time that: (i) the notes have Investment Grade Ratings from two Rating Agencies and (ii) no Default or Event of Default has occurred and is continuing under the Indenture (the occurrence of the events described in the foregoing clauses (i) and (ii) being collectively referred to as a “Covenant Suspension Event”), the Company and its Restricted Subsidiaries will not be subject to the following provisions of the Indenture:

(4) “—Limitation on Dividend and Other Payment Restrictions Affecting Subsidiaries;”

(6) clause 2 of the first paragraph of “—Consolidation, Merger and Sale of Assets;”

(collectively, the “Suspended Covenants”). Upon the occurrence of a Covenant Suspension Event, the Guarantees, if any, of any Guarantors will also be suspended as of such date (the “Suspension Date”). In the event that the Company and the Restricted Subsidiaries are not subject to the Suspended Covenants for any period of time as a result of the foregoing, and on any subsequent date (the “Reversion Date”) one or both of the Rating Agencies withdraw their Investment Grade Rating or downgrade the rating assigned to the notes below an Investment Grade Rating, then the Company and the Restricted Subsidiaries will thereafter again be subject to the Suspended Covenants with respect to future events and the Guarantees, if any, of any Guarantors will be reinstated if such Guarantees are then required by the terms of the Indenture. The period of time between the Suspension Date and the Reversion Date is referred to in this description as the “Suspension Period.” Notwithstanding that the Suspended Covenants may be reinstated, no Default or Event of Default will be deemed to have occurred as a result of a failure to comply with the Suspended Covenants during the Suspension Period (or upon termination of the Suspension Period or after that time based solely on events that occurred during the Suspension Period).

On the Reversion Date, all Indebtedness incurred, or Disqualified Capital Stock or Preferred Stock issued, during the Suspension Period will be classified as having been incurred or issued pursuant to paragraph (a) of “—Limitation on Incurrence of Additional Indebtedness” below or one of the clauses set forth in paragraph (b) of “—Limitation on Incurrence of Additional Indebtedness” below (to the extent such Indebtedness or Disqualified Capital Stock or Preferred Stock would be permitted to be incurred or issued thereunder as of the Reversion Date and after giving effect to Indebtedness incurred or issued prior to the Suspension Period and outstanding on the Reversion Date). To the extent such Indebtedness or Disqualified Capital Stock or Preferred Stock would not be so permitted to be incurred or issued pursuant to paragraph (a) or (b) of “—Limitation on Incurrence of Additional Indebtedness,” such Indebtedness or Disqualified Capital Stock or Preferred Stock will be deemed to have been outstanding on the Issue Date, so that it is classified as permitted under clause (3) of paragraph (b) of “—Limitation on Incurrence of Additional 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 covenant 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.” As described above, however, no Default or Event of Default will be deemed to have occurred on the Reversion Date as a result of any actions taken by the Company or its Restricted Subsidiaries during the Suspension Period.

(a) The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, assume, guarantee, acquire, become liable, contingently or otherwise, with respect to, or otherwise become responsible for payment of (collectively, “incur”) any Indebtedness (other than Permitted Indebtedness); provided that if no Default or Event of Default shall have occurred and be continuing at the time of or as a consequence of the incurrence of any such Indebtedness, the Company or any of its Restricted Subsidiaries may incur Indebtedness if on the date of the incurrence of such Indebtedness, after giving effect to the incurrence thereof, the Consolidated Fixed Charge Coverage Ratio of the Company would have been greater than 2.0 to 1.0; provided that the amount of Indebtedness that may be incurred and Disqualified Capital Stock or Preferred Stock that may be issued pursuant to the foregoing by any Restricted Subsidiaries that are not Guarantors (other than borrowings under a Bank Facility which is secured by Liens incurred pursuant to clause 2(a) of the “—Limitation on Liens” covenant) shall not exceed $100.0 million at any one time outstanding.

(b) The foregoing will not apply to (collectively, “Permitted Indebtedness”):

1. Indebtedness under the notes (other than any Additional Notes) issued on the Issue Date;

2. Indebtedness incurred pursuant to any Bank Facility in an aggregate principal amount at any one time outstanding not to exceed $250.0 million;

3. other Indebtedness of the Company and its Restricted Subsidiaries outstanding on the Issue Date (other than Indebtedness under clauses 1, 2 or 18 of this paragraph (b)) reduced by the amount of any scheduled amortization payments, mandatory prepayments when actually paid, conversions or permanent reductions thereof;

4. Interest Swap Obligations of the Company or any Restricted Subsidiary of the Company covering Indebtedness of the Company or any of its Restricted Subsidiaries; provided that such Interest Swap Obligations are entered into to protect the Company and its Restricted Subsidiaries from fluctuations in interest rates on its outstanding Indebtedness incurred without violation of the Indenture to the extent the notional principal amount of such Interest Swap Obligation does not, at the time of the incurrence thereof, exceed the principal amount of the Indebtedness to which such Interest Swap Obligation relates;

5. Indebtedness under Currency Agreements; provided that in the case of Currency Agreements which relate to Indebtedness, such Currency Agreements do not increase the Indebtedness of the Company and its Restricted Subsidiaries outstanding other than as a result of fluctuations in foreign currency exchange rates or by reason of fees, indemnities and compensation payable thereunder;

6. Indebtedness of a Restricted Subsidiary of the Company owing to and held by the Company or a Wholly Owned Restricted Subsidiary of the Company for so long as such Indebtedness is held by the Company or a Wholly Owned Restricted Subsidiary of the Company or the holder of a Lien permitted under the Indenture, in each case subject to no Lien held by a Person other than the Company or a Wholly Owned Restricted Subsidiary of the Company or the holder of a Lien permitted under the Indenture; provided that if as of any date any Person other than the Company or a Wholly Owned Restricted Subsidiary of the Company or the holder of a Lien permitted under the Indenture owns or holds any such Indebtedness or holds a Lien in respect of such Indebtedness, such date shall be deemed the incurrence of Indebtedness not constituting Permitted Indebtedness under this clause (6) by the issuer of such Indebtedness;

7. Indebtedness of the Company owing to and held by a Wholly Owned Restricted Subsidiary of the Company for so long as such Indebtedness is held by a Wholly Owned Restricted Subsidiary of the Company or the holder of a Lien permitted under the Indenture, in each case subject to no Lien other than a Lien permitted under the Indenture; provided that if as of any date any Person other than a Wholly Owned Restricted Subsidiary of the Company or the holder of a Lien permitted under the Indenture owns or holds any such Indebtedness or any Person holds a Lien in respect of such Indebtedness, such date shall be deemed the incurrence of Indebtedness not constituting Permitted Indebtedness under this clause 7 by the Company;

8. Indebtedness arising from the honoring by a bank or other financial institution of a check, draft or similar instrument inadvertently (except in the case of daylight overdrafts) drawn against insufficient funds in the ordinary course of business; provided that such Indebtedness is extinguished within five business days of incurrence;

9. Indebtedness of the Company or any of its Restricted Subsidiaries in respect of performance bonds, bankers’ acceptances, workers’ compensation claims, surety, bid, appeal or similar bonds, completion guarantees, payment obligations in connection with self-insurance or similar obligations, and bank overdrafts (and letters of credit in respect thereof) in the ordinary course of business;

10. Indebtedness represented by Capitalized Lease Obligations and Purchase Money Indebtedness of the Company and its Restricted Subsidiaries incurred in the ordinary course of business not to exceed (together with any Refinancing Indebtedness with respect thereto) 5.0% of Total Assets at any one time outstanding;

12. Indebtedness of the Company or any Restricted Subsidiary consisting of “earn-out” obligations, guarantees, indemnities or obligations in respect of purchase price adjustments in connection with the acquisition or disposition of assets (including Capital Stock);

13. Indebtedness incurred by the Company or any of the Restricted Subsidiaries in respect of letters of credit, bank guarantees or similar instruments issued or created in the ordinary course of business, including in respect of health, disability or other employee benefits or property, casualty or liability insurance or self-insurance or other Indebtedness with respect to reimbursement-type obligations regarding workers’ compensation claims; provided that any reimbursement obligations in respect thereof are reimbursed within 60 days following the incurrence thereof;

14. Indebtedness in respect of Sale and Leaseback Transactions in an aggregate amount not to exceed $50.0 million at any one time outstanding;

15. Acquired Indebtedness, if on the date that such Indebtedness is incurred, after giving pro forma effect thereto, (A) the Company or such Restricted Subsidiary, as the case may be, shall be able to incur at least $1.00 of additional Indebtedness (other than Permitted Indebtedness) pursuant to the first paragraph above under this covenant, or (B) the Consolidated Fixed Charge Coverage Ratio of the Company would be no less than the Consolidated Fixed Charge Coverage Ratio of the Company immediately prior to the date such Indebtedness is incurred;

16. Additional Indebtedness of the Company and its Restricted Subsidiaries in an aggregate principal amount (or accreted value) not to exceed $100.0 million at any one time outstanding (which amounts may, but need not, be incurred in whole or in part under the Bank Facility); provided that the amount of Indebtedness that may be incurred pursuant to this clause 16 by any Restricted Subsidiaries (other than borrowings under a Bank Facility which is secured by Liens incurred pursuant to clause 2(a) of the “—Limitation on Liens” covenant) that are not Guarantors shall not exceed $50.0 million at any one time outstanding;

17. Indebtedness represented by guarantees by the Company or its Restricted Subsidiaries of Indebtedness otherwise permitted to be incurred under the Indenture; provided that, in the case of a guarantee by a Restricted Subsidiary, such Restricted Subsidiary complies with the “Subsidiaries Guarantees” covenant to the extent applicable; and

(c) For purposes of determining compliance with this “Limitation on Incurrence of Additional Indebtedness” covenant, in the event that all or a portion of an item of Indebtedness meets the

criteria of more than one of the categories of Permitted Indebtedness described in clauses 1 through 18 of paragraph (b) above or is entitled to be incurred pursuant to the Consolidated Fixed Charge Coverage Ratio provisions of such covenant, the Company shall, in its sole discretion, classify (or later reclassify) such item of Indebtedness, in whole or in part, in any manner that complies with this covenant; provided that all Indebtedness outstanding under the Bank Facility up to the maximum amount permitted under clause 2 of paragraph (b) above shall be deemed to have been incurred pursuant to clause 2 of paragraph (b). Accrual of interest, whether payable in cash or in kind, accretion or amortization of original issue discount, imputed interest, the payment of interest on any Indebtedness in the form of additional Indebtedness with the same terms, and the payment of dividends on Disqualified Capital Stock in the form of additional shares of the same class of Disqualified Capital Stock will not be deemed to be an incurrence of Indebtedness or an issuance of Preferred Stock of a Restricted Subsidiary or Disqualified Capital Stock, as applicable, for purposes of this “Limitation on Incurrence of Additional Indebtedness” covenant.

(d) In addition, the Company will not, and will not permit any Restricted Subsidiary that becomes a Guarantor to, directly or indirectly, incur any Indebtedness which by its terms (or by the terms of any agreement governing such Indebtedness) is expressly subordinated in right of payment to any other Indebtedness of the Company or such Guarantor, as the case may be, unless such Indebtedness is also by its terms (or by the terms of any agreement governing such Indebtedness) made expressly subordinate to the notes or the applicable Guarantee, as the case may be, to the same extent and in the same manner as such Indebtedness is subordinated to other Indebtedness of the Company or such Guarantor, as the case may be. For purposes of the foregoing, no Indebtedness will be deemed to be subordinated in right of payment to any other Indebtedness of the Company or any Guarantor solely by virtue of such Indebtedness being unsecured or by virtue of the fact that the holders of such Indebtedness have entered into one or more intercreditor agreements giving one or more of such holders priority over the other holders in the collateral held by them.

(e) 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, in the case of term debt, or first committed, in the case of revolving credit debt; provided that if such Indebtedness is Refinancing Indebtedness 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. Notwithstanding any other provision of this covenant, the maximum amount of Indebtedness that may be incurred pursuant to this covenant will not be deemed to be exceeded with respect to any outstanding Indebtedness due solely to the result of fluctuations in the exchange rates of currencies.

Limitation on Restricted Payments. The Company will not, and will not cause or permit any of its Restricted Subsidiaries to, directly or indirectly:

1. declare or pay any dividend or make any distribution (other than dividends or distributions payable in Qualified Capital Stock of the Company) on or in respect of shares of the Company’s Capital Stock to holders of such Capital Stock;

2. purchase, redeem or otherwise acquire or retire for value any Capital Stock of the Company;

3. make any principal payment on, purchase, defease, redeem, prepay, decrease or otherwise acquire or retire for value, earlier than one year prior to any scheduled final maturity, scheduled repayment or scheduled sinking fund payment, any Subordinated Indebtedness; or

(each of the foregoing actions set forth in clauses 1, 2, 3 and 4 being referred to as a “Restricted Payment”); if at the time of such Restricted Payment or immediately after giving effect thereto,

(ii) the Company is not able to incur at least $1.00 of additional Indebtedness (other than Permitted Indebtedness) in compliance with the first paragraph under the “Limitation on Incurrence of Additional Indebtedness” covenant; or

(iii) the aggregate amount of Restricted Payments (including such proposed Restricted Payment) made subsequent to the Issue Date (the amount expended for such purposes, if other than in cash, being the fair market value of such property as determined in good faith by the Board of Directors of the Company) shall exceed the sum of:

(v) an amount equal to the Company’s Consolidated EBITDA for the period from July 1, 2011 to the end of the Company’s most recently ended fiscal quarter for which financial statements are available at the time of such Restricted Payment (the “Basket Period”) less the product of 1.4 times the Company’s Consolidated Interest Expense for the Basket Period; plus

(w) 100% of the aggregate net cash proceeds received by the Company from any Person (other than a Subsidiary of the Company) from the issuance and sale subsequent to July 1, 2011 and on or prior to the date the Restricted Payment occurs (the “Reference Date”) of Qualified Capital Stock of the Company or warrants, options or other rights to acquire Qualified Capital Stock of the Company (but excluding any debt security that is convertible into, or exchangeable for, Qualified Capital Stock, until such debt security has been converted into, or exchanged for, Qualified Capital Stock); plus

(x) without duplication of any amounts included in clause (iii)(w) above, 100% of the aggregate net cash proceeds of any equity contribution received by the Company from a holder of the Company’s Capital Stock subsequent to the Issue Date and on or prior to the Reference Date (excluding, in the case of clauses (iii)(w) and (y), any net cash proceeds from any equity offering to the extent used to redeem the notes in compliance with the provisions set forth under “—Redemption”); plus:

1. the aggregate amount returned in cash on or with respect to Investments (other than Permitted Investments) made subsequent to the Issue Date whether through interest payments, principal payments, dividends or other distributions or payments;

2. the net cash proceeds received by the Company or any of its Restricted Subsidiaries from the disposition of all or any portion of such Investments (other than to a Subsidiary of the Company);

3. upon redesignation of an Unrestricted Subsidiary as a Restricted Subsidiary (except to the extent the Investment constituted a Permitted Investment), the fair market value of such Subsidiary as of the date of such redesignation; and

4. net cash dividends or other net cash distributions paid to the Company or any Restricted Subsidiary of the Company from any Unrestricted Subsidiaries of the Company; plus:

(z) $180 million (which amount approximates the current amount of restricted payments available under the covenant “Limitation on Restricted Payments” in the Company’s outstanding 8.125% Senior Notes due 2018 as 50% of the Company’s consolidated net income through June 30, 2011);

provided that the sum of clauses (1), (2), (3) and (4) above shall not exceed the aggregate amount of all such Investments made subsequent to the Issue Date.

Notwithstanding the foregoing, the provisions set forth in the immediately preceding paragraph do not prohibit:

1. the payment of any dividend within 60 days after the date of declaration of such dividend if the dividend would have been permitted on the date of declaration;

2. the acquisition of any shares of Capital Stock of the Company, either (i) solely in exchange for shares of Qualified Capital Stock of the Company or (ii) through the application of net proceeds of a substantially concurrent sale for cash (other than to a Subsidiary of the Company) of shares of Qualified Capital Stock of the Company;

3. the acquisition of any Subordinated Indebtedness either (i) solely in exchange for shares of Qualified Capital Stock of the Company, or (ii) through the application of net proceeds of a substantially concurrent sale for cash (other than to a Subsidiary of the Company) of (a) shares of Qualified Capital Stock of the Company or (b) Refinancing Indebtedness;

4. repurchases by the Company of Common Stock of the Company from officers, directors and employees of the Company or any of its Subsidiaries or their authorized representatives upon the death, disability or termination of employment of such employees or termination of their seat on the board of the Company in an aggregate amount not to exceed $5.0 million in any calendar year;

5. repurchases of Capital Stock deemed to occur upon the exercise of stock options or warrants if such Capital Stock represents a portion of the exercise price and related statutory withholding taxes of such options or warrants;

6. payments of dividends on Disqualified Capital Stock or Preferred Stock of any Restricted Subsidiary, the incurrence or issuance of which was permitted by the Indenture;

7. cash payments in lieu of the issuance of fractional shares in connection with (i) the exercise of warrants, options or other securities convertible into or exchangeable for Capital Stock of the Company or (ii) a merger, consolidation, amalgamation or other combination involving the Company or any of its Subsidiaries;

8. the retirement of any shares of Disqualified Capital Stock of the Company by conversion into, or by exchange for, shares of Disqualified Capital Stock of the Company or out of the net cash proceeds of the substantially concurrent sale (other than to a Subsidiary of the Company) or other shares of Disqualified Capital Stock of the Company;

9. in the event of a Change of Control, and if no Default or Event of Default shall have occurred and be continuing, the payment, purchase, redemption, defeasance or other

acquisition or retirement of Subordinated Indebtedness of the Company or any Guarantor, in each case at a purchase price not greater than 101% of the principal amount of such Subordinated Indebtedness, plus accrued and unpaid interest thereon; provided that prior to such payment, purchase, redemption, defeasance or other acquisition or retirement, the Company (or a third party to the extent permitted by the Indenture) has made a Change of Control Offer with respect to the notes offered hereby as a result of such Change of Control and has repurchased all notes validly tendered and not withdrawn in connection with such Change of Control Offer;

10. in the event of an Asset Sale that requires the Company to offer to repurchase notes pursuant to the covenant described under “Limitation on Asset Sales,” and if no Default or Event of Default shall have occurred and be continuing, the payment, purchase, redemption, defeasance or other acquisition or retirement of Subordinated Indebtedness of the Company or any Guarantor, in each case at a purchase price not greater than 100% of the principal amount of such Subordinated Indebtedness, plus accrued and unpaid interest thereon; provided that (A) prior to such payment, purchase, redemption, defeasance or other acquisition or retirement, the Company has made an offer with respect to the notes offered hereby pursuant to the provisions of the covenant described under “Limitation on Asset Sales” and has repurchased all notes validly tendered and not withdrawn in connection with such offer and (B) the aggregate amount of all such payments, purchases, redemptions, defeasances or other acquisitions or retirements of all such Subordinated Indebtedness may not exceed the amount of the Net Cash Proceeds Amount remaining after the Company has complied with clause (3) of the covenant described under “Limitation on Asset Sales”;

11. the conversion, repayment, repurchase, redemption or other retirement (whether for cash or otherwise) of, or the payment of interest in respect of, the 2012 Convertible Notes and the 2016 Convertible Notes; and

12. other Restricted Payments in an aggregate amount not to exceed $50.0 million after the Issue Date.

In determining the aggregate amount of Restricted Payments made subsequent to the Issue Date in accordance with clause (iii) of the immediately preceding paragraph, amounts expended pursuant to clauses (1) and (4) shall be included in such calculation.

Limitation on Asset Sales. The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, consummate an Asset Sale unless:

1. the Company or such Restricted Subsidiary, as the case may be, receives consideration therefor at the time of such Asset Sale at least equal to the fair market value at the time of such Asset Sale of the property, assets or stock sold or otherwise disposed of (as determined in good faith by the Company’s Board of Directors);

2. at least 75% of the consideration received by the Company or the Restricted Subsidiary, as the case may be, from such Asset Sale shall be in the form of cash, Cash Equivalents and/or Replacement Assets (as defined) and is received at the time of such disposition; provided that, for purposes of this clause 2, (a) the amount of any liabilities (as shown on the Company’s or such Restricted Subsidiary’s most recent balance sheet) of the Company or any such Restricted Subsidiary (other than liabilities that are by their terms subordinated in right of payment to the notes or any Guarantee of a Guarantor) that are assumed by the transferee of any such assets, (b) the fair market value of any securities or other assets received by the Company or any such Restricted Subsidiary in exchange for any such assets that are converted into cash or Cash Equivalents within 360 days after such Asset

Sale and (c) any Designated Non-cash 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 Non-cash Consideration received pursuant to this subclause (c) that is at that time outstanding, not to exceed the greater of 1.0% of Total Assets and $50.0 million at the time of the receipt of such Designated Non-cash Consideration (with the fair market value of each item of Designated Non-cash Consideration being measured at the time received and without giving effect to subsequent changes in value), in each case shall be deemed to be cash for purposes of this provision; and

3. upon the consummation of an Asset Sale, the Company shall apply, or cause such Restricted Subsidiary to apply, the Net Cash Proceeds relating to such Asset Sale within 360 days of receipt thereof either:

(a) to permanently reduce Indebtedness under a Bank Facility or to permanently repay any secured Indebtedness (other than Subordinated Indebtedness) of the Company or any Restricted Subsidiary or any Indebtedness of any Restricted Subsidiary that is not a Guarantor;

(b) to make an investment in properties and assets (including Capital Stock) that replace the properties and assets that were the subject of such Asset Sale or in properties and assets that will be used in the business of the Company and its Restricted Subsidiaries as existing on the Issue Date or in businesses reasonably related thereto (“Replacement Assets”);

(c) to repay other Pari Passu Indebtedness; provided that the Company shall also equally and ratably reduce Indebtedness under the notes by making an offer (in accordance with the procedures set forth below for a Net Proceeds Offer) to all Holders to purchase the pro rata principal amount of notes, in each case at a purchase price equal to 100% of the principal amount thereof, plus accrued and unpaid interest to the repurchase date (subject to the right of holders of record on the relevant record date to receive interest due on the relevant interest payment date); and/or

(d) a combination of prepayment and investment permitted by the foregoing clauses (a)—(c);

provided that in the case of an investment in Replacement Assets pursuant to clause (b) or (d) above, a binding commitment shall be treated as a permitted application of the Net Cash Proceeds from the date of such commitment and, in the event such binding commitment is later cancelled or terminated for any reason before such Net Cash Proceeds are so applied, the Company or such Restricted Subsidiary enters into another binding commitment within 180 days of such cancellation or termination of the prior binding commitment.

Pending the final application of such Net Cash Proceeds, the Company may temporarily reduce borrowings under the Bank Facility or any other revolving credit facility or otherwise invest the Net Cash Proceeds in any manner not prohibited by the Indenture. On the 361st day after an Asset Sale or such earlier date, if any, as the Board of Directors of the Company or of such Restricted Subsidiary determines not to apply the Net Cash Proceeds relating to such Asset Sale as set forth in clauses 3(a)–(d) of the preceding paragraph (each, a “Net Proceeds Offer Trigger Date”), such aggregate amount of Net Cash Proceeds (rounded down to the nearest $1,000) that has not been applied on or before such Net Proceeds Offer Trigger Date as permitted in clauses 3(a)–(d) of the preceding paragraph or the last provision of this paragraph (each a “Net Proceeds Offer Amount”) shall be applied by the Company or such Restricted Subsidiary to make an offer to purchase (the “Net Proceeds Offer”) to all Holders and, to the

extent required by the terms of any Pari Passu Indebtedness, to all holders of Pari Passu Indebtedness, on a date (the “Net Proceeds Offer Payment Date”) not less than 30 nor more than 60 days following the applicable Net Proceeds Offer Trigger Date, from all Holders (and holders of any such Pari Passu Indebtedness) on a pro rata basis, the maximum amount of notes and Pari Passu Indebtedness equal to the Net Proceeds Offer Amount at a price equal to 100% of the principal amount of the notes and Pari Passu Indebtedness to be purchased, plus accrued and unpaid interest thereon, if any, to the date of purchase; provided that if at any time any non-cash consideration received by the Company or any Restricted Subsidiary of the Company, as the case may be, in connection with any Asset Sale is converted into or sold or otherwise disposed of for cash (other than interest received with respect to any such non-cash consideration), then such conversion or disposition shall be deemed to constitute an Asset Sale hereunder and the Net Cash Proceeds thereof shall be applied in accordance with this covenant.

The Company may defer the Net Proceeds Offer until there is an aggregate unutilized Net Proceeds Offer Amount equal to or in excess of $25.0 million resulting from one or more Asset Sales (at which time, the entire unutilized Net Proceeds Offer Amount, and not just the amount in excess of $25.0 million, shall be applied as required pursuant to this covenant).

In the event of the transfer of substantially all (but not all) of the property and assets of the Company and its Restricted Subsidiaries as an entirety to a Person in a transaction permitted under “—Merger, Consolidation and Sale of Assets,” which transaction does not constitute a Change of Control, the successor corporation shall be deemed to have sold the properties and assets of the Company and its Restricted Subsidiaries not so transferred for purposes of this covenant, and shall comply with the provisions of this covenant with respect to such deemed sale as if it were an Asset Sale. In addition, the fair market value of such properties and assets of the Company or its Restricted Subsidiaries deemed to be sold shall be deemed to be Net Cash Proceeds for purposes of this covenant.

Each Net Proceeds Offer will be mailed to the record Holders as shown on the register of Holders within 25 days following the Net Proceeds Offer Trigger Date, with a copy to the Trustee, and shall comply with the procedures set forth in the Indenture. Upon receiving notice of the Net Proceeds Offer, Holders may elect to tender their notes in whole or in part (of $2,000 and integral multiples of $1,000 in excess thereof) in exchange for cash. To the extent Holders properly tender notes and holders of Pari Passu Indebtedness properly tender such Pari Passu Indebtedness in an amount exceeding the Net Proceeds Offer Amount, the tendered notes and Pari Passu Indebtedness will be purchased on a pro rata basis based on the aggregate amount of notes and Pari Passu Indebtedness tendered (and the Trustee shall select the tendered notes of tendering Holders on a pro rata basis based on the amount of notes and Pari Passu Indebtedness tendered). A Net Proceeds Offer shall remain open for a period of 20 business days or such longer or shorter period as may be required or permitted, respectively, by law. If any Net Cash Proceeds remain after the consummation of any Net Proceeds Offer, the Company may use those Net Cash Proceeds for any purpose not otherwise prohibited by the Indenture. Upon completion of each Net Proceeds Offer, the amount of Net Cash Proceeds will be reset at zero.

The Company will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent such laws and regulations are applicable in connection with the repurchase of notes pursuant to a Net Proceeds Offer. To the extent that the provisions of any securities laws or regulations conflict with the “Asset Sale” provisions of the Indenture, the Company shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under the “Asset Sale” provisions of the Indenture by virtue thereof.

Limitation on Dividend and Other Payment Restrictions Affecting Subsidiaries. The Company will not, and will not cause or permit any of its Restricted Subsidiaries to, directly or indirectly,

create or otherwise cause or permit to exist or become effective any encumbrance or restriction on the ability of any Restricted Subsidiary of the Company to:

1. pay dividends or make any other distributions on or in respect of its Capital Stock;

2. make loans or advances to the Company or any other Restricted Subsidiary or to pay any Indebtedness or other obligation owed to the Company or any other Restricted Subsidiary of the Company; or

3. transfer any of its property or assets to the Company or any other Restricted Subsidiary of the Company,

except in each case for such encumbrances or restrictions existing under or by reason of:

(c) customary non-assignment provisions of any contract or any lease, license or sublicense governing a leasehold interest of any Restricted Subsidiary of the Company;

(d) any instrument governing Acquired Indebtedness, which encumbrance or restriction is not applicable to any Person, or the properties or assets of any Person, other than the Person or the properties or assets of the Person so acquired;

(e) agreements existing on the Issue Date to the extent and in the manner such agreements are in effect on the Issue Date;

(f) the Bank Facility, an agreement governing other Pari Passu Indebtedness permitted to be incurred under the Indenture or, with respect to a Restricted Subsidiary, an agreement evidencing Indebtedness incurred not in violation of the Indenture; provided that, with respect to any agreement governing such other Pari Passu Indebtedness or other Indebtedness, as the case may be, the provisions relating to such encumbrance or restriction are no less favorable to the Company or Restricted Subsidiary, as the case may be, in any material respect as determined by the Board of Directors of the Company in its reasonable and good faith judgment than the provisions contained in the Bank Facility, in the case of such other Pari Passu Indebtedness, and the agreements of such Restricted Subsidiary, in the case of such other Indebtedness, in each case as in effect on the Issue Date;

(g) restrictions on the transfer of assets subject to any Lien permitted under the Indenture imposed by the holder of such Lien;

(h) restrictions imposed by any agreement to sell assets or Capital Stock permitted under the Indenture to any Person pending the closing of such sale;

(i) such encumbrances or restrictions being binding on a Restricted Subsidiary at such time as such Restricted Subsidiary first becomes a Restricted Subsidiary, provided that such encumbrances or restrictions are not entered into solely in contemplation of such Person becoming a Restricted Subsidiary;

(j) customary provisions in joint venture agreements and other similar agreements (in each case relating solely to the respective joint venture or similar entity or the equity interests therein) entered into in the ordinary course of business;

(k) any amendment to or Refinancing of the Indebtedness issued, assumed or incurred pursuant to an agreement referred to in clauses (b), (d), (e) and (f) above; provided that the provisions relating to such encumbrance or restriction contained in any such agreement, taken as a whole, are no less favorable to the Company in any material respect as determined by the Board of Directors of the Company in their reasonable and good faith judgment than the provisions relating to such encumbrance or restriction contained in agreements referred to in such clauses (b), (d), (e) and (f);

(l) customary restrictions on leases, subleases, licenses, sublicenses or asset sale agreements otherwise permitted hereby;

(m) restrictions imposed on cash or other deposits or net worth imposed by customers or required by insurance, surety or bonding companies, in each case, entered into in the ordinary course of business; and

(n) encumbrances and restrictions applicable only to Restricted Subsidiaries of the Company that are not Domestic Restricted Subsidiaries.

Limitation on Preferred Stock of Domestic Restricted Subsidiaries. The Company will not permit any of its Domestic Restricted Subsidiaries that are not Guarantors to issue any Preferred Stock (other than to the Company or to a Wholly Owned Restricted Subsidiary of the Company) or permit any Person (other than the Company or a Wholly Owned Restricted Subsidiary of the Company) to own any Preferred Stock of any Domestic Restricted Subsidiary of the Company that is not a Guarantor.

Limitation on Liens. The Company will not, and will not cause or permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, assume or permit or suffer to exist any Liens of any kind against or upon any property or assets of the Company or any of its Restricted Subsidiaries whether owned on the Issue Date or acquired after the Issue Date, or any proceeds therefrom, or assign or otherwise convey any right to receive income or profits therefrom unless:

1. in the case of Liens securing Subordinated Indebtedness, the notes or any Guarantee, as the case may be, are secured by a Lien on such property, assets or proceeds that is senior in priority to such Liens; and

2. in all other cases, the notes or any Guarantee, as the case may be, are equally and ratably secured, except for:

(a) Liens securing borrowings under a Bank Facility in an amount not to exceed the greater of (x) the amount permitted to be incurred pursuant to and in compliance with clause (b)(2) of the covenant “—Limitation on Incurrence of Additional Indebtedness” and (y) such amount that at the time of such granting and after giving pro forma effect to any such Lien and obligations secured thereunder (including the use of proceeds thereof) the Company and its Restricted Subsidiaries shall have a Secured Leverage Ratio less than or equal to 1.5 to 1.0;

(b) Liens existing as of the Issue Date to the extent and in the manner such Liens are in effect on the Issue Date;

(c) Liens securing the Company’s and its Restricted Subsidiaries’ Obligations under any hedge facility permitted under the Indenture to be entered into by the Company and its Restricted Subsidiaries;

(e) Liens in favor of the Company or a Wholly Owned Restricted Subsidiary of the Company on assets of any Restricted Subsidiary of the Company;

(f) Liens securing Refinancing Indebtedness which is incurred to Refinance any Indebtedness which has been secured by a Lien permitted under the Indenture and which has been incurred in accordance with the provisions of the Indenture; provided that such Liens: (i) are no less favorable to the Holders in any material respect and are not more favorable to the lienholders in any material respect with respect to such Liens than the Liens in respect of the Indebtedness being Refinanced as determined by the Board of Directors of the Company in its reasonable and good faith judgment; and (ii) do not extend to or cover any property or assets of the Company or any of its Restricted Subsidiaries not securing the Indebtedness so Refinanced; and

Consolidation, Merger and Sale of Assets. The Company will not, in a single transaction or series of related transactions, consolidate or merge with or into any Person, or sell, assign, transfer, lease, convey or otherwise dispose of (or cause or permit any Restricted Subsidiary of the Company to sell, assign, transfer, lease, convey or otherwise dispose of) all or substantially all of the Company’s assets (determined on a consolidated basis for the Company and the Company’s Restricted Subsidiaries) whether as an entirety or substantially as an entirety to any Person unless:

(b) the Person (if other than the Company) formed by such consolidation or into which the Company is merged or the Person which acquires by sale, assignment, transfer, lease, conveyance or other disposition the properties and assets of the Company and of the Company’s Restricted Subsidiaries substantially as an entirety (the “Surviving Entity”);

(x) shall be an entity organized and validly existing under the laws of the United States or any State thereof or the District of Columbia; provided that in the case where the Surviving Entity is not a corporation, a co-obligor of the notes is a corporation; and

(y) shall expressly assume, by supplemental indenture (in form and substance satisfactory to the Trustee), executed and delivered to the Trustee, the due and punctual payment of the principal of, and premium, if any, and interest on all of the notes and the performance of every covenant of the notes and the Indenture on the part of the Company to be performed or observed;

2. immediately after giving effect to such transaction and the assumption contemplated by clause 1(b)(y) above (including giving effect to any Indebtedness and Acquired Indebtedness incurred or anticipated to be incurred in connection with or in respect of such transaction), (A) the Company or such Surviving Entity, as the case may be, shall be able to incur at least $1.00 of additional Indebtedness (other than Permitted Indebtedness) pursuant to the first paragraph of the “Limitation on Incurrence of Additional Indebtedness” covenant or (B) the applicable Consolidated Fixed Charge Coverage Ratio of the Company or the Person formed by or surviving any such consolidation or merger (if other than the Company) would be no less than the applicable Consolidated Fixed Charge Coverage Ratio of the Company immediately prior to such transaction;

3. immediately before and immediately after giving effect to such transaction and the assumption contemplated by clause 1(b)(y) above (including, without limitation, giving effect to any Indebtedness and Acquired Indebtedness incurred or anticipated to be incurred and any Lien granted in connection with or in respect of the transaction), no Default or Event of Default shall have occurred or be continuing; and

4. the Company or the Surviving Entity shall have delivered to the Trustee an officers’ certificate and an opinion of counsel, each stating that such consolidation, merger, sale, assignment, transfer, lease, conveyance or other disposition and, if a supplemental indenture is required in connection with such transaction, such supplemental indenture complies with the applicable provisions of the Indenture and that all conditions precedent in the Indenture relating to such transaction have been satisfied.

For purposes of the foregoing, the transfer (by lease, assignment, sale or otherwise, in a single transaction or series of transactions) of all or substantially all of the properties or assets of one or more Restricted Subsidiaries of the Company, in a single or a series of related transactions, which properties and assets, if held by the Company instead of such Restricted Subsidiaries, would constitute all or substantially all of the properties and assets of the Company on a consolidated basis, shall be deemed to be the transfer of all or substantially all of the properties and assets of the Company.

Notwithstanding the foregoing clauses 1, 2 and 3, but subject to the proviso in subclause (x) of clause 1(b), the Company may merge with (a) any of its Wholly Owned Restricted Subsidiaries or (b) an Affiliate that is a Person that has no material assets or liabilities and which was organized solely for the purpose of reorganizing the Company in another jurisdiction.

The Indenture will provide that upon any consolidation, combination or merger or any transfer of all or substantially all of the assets of the Company in accordance with the foregoing in which the Company is not the continuing corporation, the successor Person formed by such consolidation or into which the Company is merged or to which such conveyance, lease or transfer is made shall succeed to, and be substituted for, and may exercise every right and power of, the Company under the Indenture and the notes with the same effect as if such surviving entity had been named as such and all financial information and reports required by the Indenture shall be provided by and for such surviving entity.

To the extent that the notes are guaranteed by one or more Guarantors pursuant to the “Subsidiary Guarantees” covenant, such Guarantors will be subject to similar provisions relating to the consolidation, merger or sale of assets of such Guarantors.

(a) The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, enter into or permit to exist any transaction or series of related transactions (including, without limitation, the purchase, sale, lease or exchange of any property or the rendering of any service) with, or for the benefit of, any of its Affiliates (each an “Affiliate Transaction”), having a value greater than $5.0 million other than (x) Affiliate Transactions permitted under paragraph (b) below and (y) Affiliate Transactions on terms that are no less favorable than those that might reasonably have been obtained in a comparable transaction at such time on an arm’s-length basis from a Person that is not an Affiliate of the Company or such Restricted Subsidiary.

All Affiliate Transactions (and each series of related Affiliate Transactions which are similar or part of a common plan) involving aggregate payments or other property with a fair market value in excess of $25.0 million shall be approved by the Board of Directors of the Company or such

Restricted Subsidiary, as the case may be, such approval to be evidenced by a Board Resolution stating that such Board of Directors has determined that such transaction complies with the foregoing provisions. If the Company or any Restricted Subsidiary of the Company enters into an Affiliate Transaction (or a series of related Affiliate Transactions related to a common plan) that involves an aggregate fair market value of more than $50.0 million, the Company or such Restricted Subsidiary, as the case may be, shall, prior to the consummation thereof, obtain a favorable opinion as to the fairness of such transaction or series of related transactions to the Company or the relevant Restricted Subsidiary, as the case may be, from a financial point of view, from an Independent Financial Advisor and file the same with the Trustee.

1. loans, advances and payments of reasonable fees and compensation paid (whether in cash or the issuance of Capital Stock of the Company) to and indemnity provided on behalf of, officers, directors, employees or consultants of the Company or any Restricted Subsidiary of the Company in the ordinary course of business or as determined in good faith by the Company’s Board of Directors or senior management;

2. transactions exclusively between or among the Company and any of its Restricted Subsidiaries or exclusively between or among such Restricted Subsidiaries, provided that such transactions are not otherwise prohibited by the Indenture;

3. any agreement as in effect as of the Issue Date or any amendment thereto or any transaction contemplated thereby (including pursuant to any amendment thereto) in any replacement agreement thereto so long as any such amendment or replacement agreement, taken as a whole, is not materially more disadvantageous to the Holders than the original agreement as in effect on the Issue Date;

4. any transaction on arm’s-length terms with any non-Affiliate that becomes an Affiliate as a result of such transaction;

5. any employment, consulting and severance arrangements entered into by the Company or any of its Restricted Subsidiaries in the ordinary course of business;

7. Permitted Investments and Restricted Payments permitted by the Indenture; and

8. the payment of customary fees and reasonable out-of-pocket costs to, and indemnities provided on behalf of, directors, officers and employees of the Company and the Restricted Subsidiaries in the ordinary course of business to the extent attributable to the ownership or operation of the Company and the Restricted Subsidiaries.

Subsidiary Guarantees. If any existing or future Domestic Restricted Subsidiary shall, after the Issue Date, guarantee any Public Debt Securities, then the Company shall cause such Domestic Restricted Subsidiary to:

1. execute and deliver to the Trustee a supplemental indenture in form reasonably satisfactory to the Trustee pursuant to which such Restricted Subsidiary shall unconditionally guarantee all of the Company’s obligations under the notes and the Indenture on the terms set forth in the Indenture; and

2. deliver to the Trustee an officers’ certificate and an opinion of counsel that such supplemental indenture has been duly authorized, executed and delivered by such Restricted

Subsidiary and constitutes a legal, valid, binding and enforceable obligation of such Restricted Subsidiary.

Thereafter, such Domestic Restricted Subsidiary shall be a Guarantor for all purposes of the Indenture until such Domestic Restricted Subsidiary is released from its Guarantee as provided in the Indenture.

Conduct of Business. The Company and its Restricted Subsidiaries will not engage in any businesses that are not the same, similar, ancillary, complementary or reasonably related to the businesses in which the Company and its Restricted Subsidiaries are engaged on the Issue Date, except to an extent that so doing would not be material to the Company and its Restricted Subsidiaries, taken as a whole.

Payments for Consent. The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, pay or cause to be paid any consideration to or for the benefit of any Holder of notes for or as an inducement to any consent, waiver or amendment of any of the terms or provisions of the Indenture or the notes unless such consideration is offered to be paid and is paid to all Holders of the notes that consent, waive or agree to amend in the time frame set forth in the solicitation documents relating to such consent, waiver or agreement.

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

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

provided that the foregoing delivery requirements shall be deemed satisfied if the foregoing materials are available on the Commission’s EDGAR system or on the Company’s website within the applicable time period.

In addition, whether or not required by the Commission, the Company will, if the Commission will accept the filing, file a copy of all of the information and reports referred to in clauses (1) and (2) with the Commission for public availability within the time periods specified in the Commission’s rules and regulations. In addition, the Company will make the information and reports available to securities analysts and prospective investors upon request. If the Company had any Unrestricted Subsidiaries during the relevant period, the Company will also provide to the Trustee and, upon request, to any Holder of the notes, information sufficient to ascertain the financial condition and results of operations of the Company and its Restricted Subsidiaries, excluding in all respects the Unrestricted Subsidiaries.

Notwithstanding anything to the contrary herein, the Company will not be deemed to have failed to comply with any of its obligations hereunder for purposes of clause (3) under “—Events of Default” until 90 days after the date any report hereunder is due to be delivered to the Trustee.

(1) the failure to pay interest on any notes when the same becomes due and payable and the default continues for a period of 30 days;

(2) the failure to pay the principal on any notes, when such principal becomes due and payable, at maturity, upon redemption or otherwise (including the failure to make a payment to purchase notes tendered pursuant to a Change of Control Offer or a Net Proceeds Offer) on the date specified for such payment in the applicable offer to purchase;

(3) a default in the observance or performance of any other covenant or agreement contained in the Indenture which default continues for a period of 60 days after the Company receives written notice specifying the default (and demanding that such default be remedied) from the Trustee or the Holders of at least 25% of the outstanding principal amount of the notes (except in the case of a default with respect to the “Merger, Consolidation and Sale of Assets” covenant, which will constitute an Event of Default with such notice requirement but without such passage of time requirement);

(4) the failure to pay at final maturity (giving effect to any applicable grace periods and any extensions thereof) the stated principal amount of any Indebtedness of the Company or any Restricted Subsidiary of the Company, or the acceleration of the final stated maturity of any such Indebtedness (which acceleration is not rescinded, annulled or otherwise cured within 20 days of receipt by the Company or such Restricted Subsidiary of notice of any such acceleration) if the aggregate principal amount of such Indebtedness, together with the principal amount of any other such Indebtedness in default for failure to pay principal at final stated maturity or which has been so accelerated (in each case with respect to which the 20-day period described above has passed), equals $75.0 million or more at any time;

(5) one or more judgments in an aggregate amount in excess of $75.0 million shall have been rendered against the Company or any of its Restricted Subsidiaries and such judgments remain undischarged, unpaid or unstayed for a period of 60 days after such judgment or judgments become final and non-appealable;

(6) certain events of bankruptcy affecting the Company or any of its Material Subsidiaries; or

(7) any Guarantee of a Guarantor that is a Material Subsidiary (or group of Guarantors that would constitute a Material Subsidiary) or any material provision thereof ceases to be in full force and effect or any Guarantee of a Guarantor is declared to be null and void and unenforceable or any Guarantee of a Guarantor is found to be invalid or any Guarantor denies its liability under its Guarantee (other than by reason of release of a Guarantor in accordance with the terms of the Indenture).

If an Event of Default (other than an Event of Default specified in clause (6) above with respect to the Company) shall occur and be continuing, the Trustee or the Holders of at least 25% in principal amount of outstanding notes may declare the principal of and accrued interest on all the notes to be due and payable by notice in writing to the Company and the Trustee specifying the respective Event of Default and that it is a “notice of acceleration,” and the same shall become immediately due and payable.

If an Event of Default specified in clause (6) above with respect to the Company occurs and is continuing, then all unpaid principal of, and premium, if any, and accrued and unpaid interest on

all of the outstanding notes shall ipso facto become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holder.

The Indenture will provide that, at any time after a declaration of acceleration with respect to the notes as described in the preceding paragraphs, the Holders of a majority in principal amount of the notes may rescind and cancel such declaration and its consequences:

2. if all existing Events of Default have been cured or waived except nonpayment of principal or interest that has become due solely because of the acceleration;

3. to the extent the payment of such interest is lawful, interest on overdue installments of interest and overdue principal, which has become due otherwise than by such declaration of acceleration, has been paid;

4. if the Company has paid the Trustee its reasonable compensation and reimbursed the Trustee for its expenses, disbursements and advances; and

5. in the event of the cure or waiver of an Event of Default of the type described in clause (6) of the description above of Events of Default, the Trustee shall have received an officers’ certificate and an opinion of counsel that such Event of Default has been cured or waived. No such rescission shall affect any subsequent Default or impair any right consequent thereto.

The Holders of a majority in principal amount of the notes may waive any existing Default or Event of Default under the Indenture, and its consequences, except a default in the payment of the principal of or interest on any notes.

Holders of the notes may not enforce the Indenture or the notes except as provided in the Indenture and under the TIA. Subject to the provisions of the Indenture relating to the duties of the Trustee, the Trustee is under no obligation to exercise any of its rights or powers under the Indenture at the request, order or direction of any of the Holders, unless such Holders have offered to the Trustee reasonable indemnity. Subject to all provisions of the Indenture and applicable law, the Holders of a majority in aggregate principal amount of the then outstanding notes have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on the Trustee.

Under the Indenture, the Company is required to provide an officers’ certificate to the Trustee promptly upon any such officer obtaining knowledge of any Default or Event of Default (provided that such officers shall provide such certification at least annually whether or not they know of any Default or Event of Default) that has occurred and, if applicable, describe such Default or Event of Default and the status thereof.

No past, present or future director, officer, employee, incorporator, agent, stockholder or Affiliate of the Company, as such, shall have any liability for any obligations of the Company under the notes or under the Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation. No past, present or future director, officer, employee, incorporator, agent, stockholder or Affiliate of any of the Guarantors, as such, shall have any liability for any obligations of the Guarantors under any Guarantees or the Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder of notes by accepting a note waives and releases all such liabilities. The waiver and release are part

of the consideration for the issuance of the notes and any Guarantees. Such waiver may not be effective to waive liabilities under federal securities law, and it is the view of the Commission that such a waiver is against public policy.

The Company may, at its option and at any time, elect to have its obligations and the obligations of the Guarantors discharged with respect to the outstanding notes (“Legal Defeasance”). Such Legal Defeasance means that the Company shall be deemed to have paid and discharged the entire Indebtedness represented by the outstanding notes, except for:

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

2. the Company’s obligations with respect to the notes concerning issuing temporary notes, registration of notes, mutilated, destroyed, lost or stolen notes and the maintenance of an office or agency for payments;

3. the rights, powers, trust, duties and immunities of the Trustee and the Company’s obligations in connection therewith; and

In addition, the Company may, at its option and at any time, elect to have the obligations of the Company released with respect to certain covenants that are described in the Indenture (“Covenant Defeasance”) and thereafter any omission to comply with such obligations shall not constitute a Default or Event of Default with respect to the notes. In the event Covenant Defeasance occurs, certain events (not including non-payment, bankruptcy, receivership, reorganization and insolvency events) described under “—Events of Default” will no longer constitute an Event of Default with respect to the notes.

1. the Company must irrevocably deposit with the Trustee, in trust, for the benefit of the Holders, cash in U.S. dollars, non-callable U.S. government obligations, rated AAA or better by S&P and Aaa by Moody’s, or a combination thereof, in such amounts as will be sufficient, in the opinion of a nationally recognized firm of independent public accountants, to pay the principal of, premium, if any, and interest on the notes on the stated date for payment thereof or on the applicable redemption date, as the case may be;

2. in the case of Legal Defeasance, the Company shall have delivered to the Trustee an opinion of counsel in the United States reasonably acceptable to the Trustee confirming that:

(a) the Company has received from, or there has been published by, the Internal Revenue Service a ruling; or

(b) since the date of the Indenture, there has been a change in the applicable federal income tax law,

in either case to the effect that, and based thereon such opinion of counsel shall confirm that, the Holders will not recognize income, gain or loss for federal income tax purposes as a result of such Legal Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Legal Defeasance had not occurred;

3. in the case of Covenant Defeasance, the Company shall have delivered to the Trustee an opinion of counsel in the United States reasonably acceptable to the Trustee confirming that the Holders 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 shall have occurred and be continuing on the date of such deposit (other than a Default or an Event of Default resulting from the borrowing of funds to be applied to such deposit and the grant of any Lien securing such borrowings);

5. such Legal Defeasance or Covenant Defeasance shall not result in a breach or violation of, or constitute a default under the Indenture (other than a Default or an Event of Default resulting from the borrowing of funds to be applied to such deposit and the grant of any Lien securing such borrowings) or any other material agreement or instrument to which the Company or any of its Restricted Subsidiaries is a party or by which the Company or any of its Restricted Subsidiaries is bound;

6. the Company shall have delivered to the Trustee an officers’ certificate stating that the deposit was not made by the Company with the intent of preferring the Holders over any other creditors of the Company or with the intent of defeating, hindering, delaying or defrauding any other creditors of the Company or others;

7. the Company shall have delivered to the Trustee an officers’ certificate and an opinion of counsel, which opinion may be subject to customary assumptions and exclusions, each stating that all conditions precedent provided for or relating to the Legal Defeasance or the Covenant Defeasance have been complied with;

8. the Company shall have delivered to the Trustee an opinion of counsel to the effect that assuming no intervening bankruptcy of the Company between the date of deposit and the 124th day following the date of deposit and that no Holder is an insider of the Company, after the 124th day following the date of deposit, the trust funds will not be subject to the effect of any applicable bankruptcy, insolvency, reorganization or similar laws affecting creditors’ rights generally; and

Notwithstanding the foregoing, the opinion of counsel required by clause 2 above with respect to a Legal Defeasance need not be delivered if all notes not theretofore delivered to the Trustee for cancellation (1) have become due and payable or (2) will become due and payable on the maturity date or a redemption date within one year under arrangements reasonably satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name, and at the expense, of the Company.

The Indenture will be discharged and will cease to be of further effect (except as to surviving rights or registration of transfer or exchange of the notes, as expressly provided for in the Indenture) as to all outstanding notes when:

(a) all the notes theretofore authenticated and delivered (except lost, stolen or destroyed notes which have been replaced or paid and notes for whose payment money

has theretofore been deposited in trust or segregated and held in trust by the Company and thereafter repaid to the Company or discharged from such trust) have been delivered to the Trustee for cancellation; or

(b) all notes not theretofore delivered to the Trustee for cancellation (1) have become due and payable or (2) will become due and payable within one year, or are to be called for redemption within one year, under arrangements reasonably satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name, and at the expense, of the Company, and the Company has irrevocably deposited or caused to be deposited with the Trustee funds in an amount sufficient to pay and discharge the entire Indebtedness on the notes not theretofore delivered to the Trustee for cancellation, for principal of, premium, if any, and interest on the notes to the date of maturity or redemption, as the case may be, together with irrevocable instructions from the Company directing the Trustee to apply such funds to the payment thereof at maturity or redemption, as the case may be;

2. the Company has paid all other sums payable under the Indenture by the Company; and

3. the Company has delivered to the Trustee an officers’ certificate and an opinion of counsel, which opinion may be subject to customary assumptions and exclusions, stating that all conditions precedent under the Indenture relating to the satisfaction and discharge of the Indenture have been complied with.

Except as provided in the next two succeeding paragraphs, the Company and the Trustee with the consent of the holders of at least a majority in aggregate principal amount of the notes then outstanding (including consents obtained in connection with a tender offer or exchange offer for the notes) may amend the Indenture, the notes or any Guarantees and the holders of at least a majority in aggregate principal amount of the notes outstanding may waive any past default or compliance with any provisions of the Indenture, the notes or any Guarantees.

Without the consent of each holder of an outstanding note, no amendment or waiver may:

2. reduce the rate of or change or have the effect of changing the time for payment of interest, including defaulted interest, on any notes;

3. reduce the principal of or change or have the effect of changing the fixed maturity of any notes, or change the date on which any notes may be subject to redemption or reduce the redemption price therefor, other than prior to the Company’s obligation to purchase notes under provisions relating to the Company’s obligation to make and consummate a Change of Control Offer in the event of a Change of Control or to make and consummate a Net Proceeds Offer with respect to any Asset Sale;

5. make any change in provisions of the Indenture protecting the right of each Holder to receive payment of principal of and interest on such note on or after the due date thereof or to bring suit to enforce such payment (except a rescission of acceleration of the notes by the Holders of at least a majority in aggregate principal amount of the notes and a waiver of the payment default that resulted from such acceleration), or permitting Holders of a majority in principal amount of notes to waive Defaults or Events of Default;

6. after the Company’s obligation to purchase notes arises thereunder, amend, change or modify in any material respect the obligation of the Company to make and consummate a Change of Control Offer in the event of a Change of Control or make and consummate a Net Proceeds Offer with respect to any Asset Sale that has been consummated or, after such Change of Control has occurred or such Asset Sale has been consummated, modify any of the provisions or definitions with respect thereto;

7. modify or change any provision of the Indenture or the related definitions affecting the ranking of the notes or any Guarantee in a manner which adversely affects the Holders;

8. release any Guarantor that is a Material Subsidiary from any of its obligations under its Guarantee or the Indenture otherwise than in accordance with the terms of the Indenture; or

The Indenture and the notes may be amended by the Company and the Trustee without the consent of any holder of the notes to:

2. provide for the assumption by a Surviving Person of the obligations of the Company under the Indenture;

3. provide for uncertificated notes in addition to or in place of certificated notes (provided that the uncertificated notes are issued in registered form for purposes of Section 163(f) of the Code, or in a manner such that the uncertificated notes are described in Section 163(f)(2)(B) of the Code);

4. add Guarantees with respect to the notes or confirm and evidence the release, termination or discharge of any security or Guarantee when such release, termination or discharge is permitted by the Indenture;

5. secure the notes, add to the covenants of the Company for the benefit of the holders of the notes or surrender any right or power conferred upon the Company;

6. make any change that does not adversely affect the rights of any holder of the notes;

7. comply with any requirement of the Commission in connection with the qualification of the Indenture under the Trust Indenture Act;

8. provide for the issuance of Additional Notes in accordance with the Indenture;

9. evidence and provide for the acceptance of appointment by a successor Trustee;

10. conform the text of the Indenture or the notes to any provision of this “Description of Notes” to the extent that such provision in this “Description of Notes” was intended to be a recitation of a provision of the Indenture or the notes; or

11. make any amendment to the provisions of the Indenture relating to the transfer and legending of the notes as permitted by the Indenture, including, without limitation to facilitate the issuance and administration of the notes; provided that (i) compliance with the Indenture as so amended would not result in the notes being transferred in violation of the Securities Act or any applicable securities law and (ii) such amendment does not materially and adversely affect the rights of Holders to transfer the notes.

The consent of the holders of the notes is not necessary to approve the particular form of any proposed amendment. It is sufficient if such consent approves the substance of the proposed amendment.

The Indenture will provide that it, the notes and any Guarantees will be governed by, and construed in accordance with, the laws of the State of New York but without giving effect to applicable principles of conflicts of law to the extent that the application of the law of another jurisdiction would be required thereby.

The Indenture will provide that, except during the continuance of an Event of Default, the Trustee will perform only such duties as are specifically set forth in the Indenture. During the existence of an Event of Default, the Trustee will exercise such rights and powers vested in it by the Indenture, and use the same degree of care and skill in its exercise as a prudent person would exercise or use under the circumstances in the conduct of his own affairs.

The Indenture and the provisions of the TIA contain certain limitations on the rights of the Trustee, should it become a creditor of the Company, to obtain payments of claims in certain cases or to realize on certain property received in respect of any such claim as security or otherwise. Subject to the TIA, the Trustee will be permitted to engage in other transactions; provided that if the Trustee acquires any conflicting interest as described in the TIA, it must eliminate such conflict or resign.

Any action required or permitted to be taken by the Board of Directors of the Company pursuant to the terms of the Indenture may be taken by a duly constituted committee of the Board of Directors of the Company.

The notes will be issued in the form of one or more fully registered global notes without coupons that will be deposited with The Depository Trust Company, New York, New York, which we refer to in this prospectus supplement as DTC, and registered in the name of its nominee, Cede & Co. This means that the Company will not issue certificates to each owner of notes. The global notes will be issued to DTC, which will keep a computerized record of its participants (for example, your broker) whose clients have purchased the notes. The participant will then keep a record of its clients who purchased the notes. Unless it is exchanged in whole or in part for a certificated note, a global note may not be transferred, except that DTC, its nominees, and their successors may transfer a global note as a whole to one another.

DTC has provided the following information to us. DTC, the world’s largest securities depositary, is a:

DTC holds and provides asset servicing for over 3.6 million of U.S. and non-U.S. equity issues, corporate and municipal debt issues, and money market instruments (from over 100 countries) that its direct participants deposit with DTC. DTC also facilitates the post-trade settlement among direct participants of sales and other securities transactions in deposited securities, through electronic computerized book-entry transfers and pledges between direct participants’ accounts. This eliminates the need for physical movement of securities certificates. Direct participants include both U.S. and non-U.S. securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations. DTC is a wholly owned subsidiary of The Depository Trust & Clearing Corporation (“DTCC”). DTCC is the holding company for DTC, National Securities Clearing Corporation and Fixed Income Clearing Corporation, all of which are registered clearing agencies. DTCC is owned by users of its regulated subsidiaries. Access to DTC’s book-entry system is also available to indirect participants such as securities brokers and dealers, banks and trust companies that clear through or maintain a custodial relationship with a direct participant, either directly or indirectly. DTC has Standard & Poor’s highest rating: AAA. The rules applicable to DTC and its direct and indirect participants are on file with the Commission.

Principal and interest payments on global notes registered in the name of DTC’s nominee will be made in immediately available funds to DTC’s nominee as the registered owner of the global notes. We and the Trustee will treat DTC’s nominee as the owner of the global notes for all other purposes as well. Accordingly, we, the Trustee and any paying agent will have no direct responsibility or liability to pay amounts due on the global notes to owners of beneficial interests in the global notes. DTC’s practice is to credit direct participants’ accounts upon receipt of any payment of principal or interest on the payment date in accordance with their respective holdings of beneficial interests in the global notes as shown on DTC’s records. Payments by direct and indirect participants to owners of beneficial interests in the global notes will be governed by standing instructions and customary practices. These payments will be the responsibility of the direct and indirect participants and not of DTC, the Trustee or us, subject to any statutory or regulatory requirements as may be in effect from time to time.

Notes that are represented by a global note, will be exchangeable for certificated notes with the same terms in authorized denominations only if:

The information in this section concerning DTC and DTC’s book-entry system has been obtained from sources that we believe to be reliable, but we take no responsibility for the accuracy thereof.

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

1. interest on outstanding Indebtedness determined on a fluctuating basis as of the Transaction Date and which will continue to be so determined thereafter shall be deemed to have accrued at a fixed rate per annum equal to the rate of interest on such Indebtedness in effect on the Transaction Date; and

2. notwithstanding clause 1 above, interest on Indebtedness determined on a fluctuating basis, to the extent such interest is covered by agreements relating to Interest Swap Obligations, shall be deemed to accrue at the rate per annum resulting after giving effect to the operation of such agreements.

The following are the material U.S. federal income tax consequences of ownership and disposition of the notes. This discussion only applies to notes that are:

This discussion does not describe all of the tax consequences that may be relevant to a holder in light of the holder’s particular circumstances, including alternative minimum tax consequences, or tax consequences applicable to holders subject to special rules, such as:

If an entity or arrangement that is classified as a partnership for U.S. federal income tax purposes holds notes, the U.S. federal income tax treatment of a partner will generally depend on the status of the partner and the activities of the partnership. Partnerships holding notes and partners in such partnerships should consult their tax advisors as to the particular U.S. federal income tax consequences of holding and disposing of the notes.

This summary is based on the Internal Revenue Code of 1986, as amended to the date hereof, administrative pronouncements, judicial decisions and final, temporary and proposed Treasury Regulations, changes to any of which subsequent to the date of this prospectus may affect the tax consequences described herein. Persons considering the purchase of notes are urged to consult their tax advisors with regard to the application of the U.S. federal income tax laws to their particular situations as well as any tax consequences arising under the laws of any state, local or foreign taxing jurisdiction.

As used herein, the term “U.S. Holder” means a beneficial owner of a note that is, for U.S. federal income tax purposes:

The term “U.S. Holder” also includes certain former citizens and residents of the United States.

Potential Contingent Payment Debt Treatment. Under certain circumstances, Equinix may pay holders amounts in excess of the stated interest and principal payable on the notes. For instance, Equinix would be required to offer to repurchase notes in the circumstances described under “Description of Notes—Certain Covenants—Limitation on Asset Sales” and “Description of Notes—Change of Control.” Although the issue is not free from doubt, Equinix intends to take the position that the possibility of such payments does not result in the notes being treated as contingent payment debt instruments under the applicable Treasury Regulations. Equinix’s position is not binding on the Internal Revenue Service (the “IRS”). If the IRS successfully takes a contrary position, U.S. Holders would be required to treat any gain recognized on the sale or other disposition of the notes as ordinary income rather than as capital gain. Furthermore, U.S. Holders would be required to accrue interest income on a constant yield basis at an assumed yield determined at the time of issuance of the notes, with adjustments to such accruals when any contingent payments are made that differ from the payments calculated based on the assumed yield. U.S. Holders should consult their tax advisors regarding the tax consequences of the notes being treated as contingent payment debt instruments. The remainder of this discussion assumes that the notes are not treated as contingent payment debt instruments.

Payments of Interest. It is expected, and therefore this discussion assumes, that the notes will be issued without original issue discount for U.S. federal income tax purposes. Accordingly, stated interest paid on a note will be taxable to a U.S. Holder as ordinary interest income at the time it accrues or is received in accordance with the U.S. Holder’s method of accounting for federal income tax purposes. If, however, the notes’ principal amount exceeds the issue price by more than a de minimis amount, as determined under applicable Treasury Regulations, a U.S. Holder will be required to include such excess in income as original issue discount, as it accrues, in accordance with a constant yield method based on a compounding of interest before the receipt of cash payments attributable to this income.

Sale, Exchange, Redemption or Retirement of the Notes. Upon the sale, exchange, redemption or retirement of a note, a U.S. Holder will recognize taxable gain or loss equal to the difference between the amount realized on the sale, exchange or retirement and the U.S. Holder’s tax basis in the note. For these purposes, the amount realized does not include any amount attributable to accrued stated interest. Amounts attributable to accrued stated interest are treated as interest as described under “—Payments of Interest” above.

Gain or loss realized on the sale, exchange or retirement of a note will generally be capital gain or loss and will be long-term capital gain or loss if at the time of sale, exchange or retirement the note has been held for more than one year. Long term capital gains recognized by non-corporate U.S. Holders are currently subject to reduced tax rates. The deductibility of capital losses may be subject to limitations.

Backup Withholding and Information Reporting. Information returns will generally be filed with the IRS in connection with payments on the notes (including accruals of original issued discount, if any) and the proceeds from a sale, exchange, redemption, retirement or other disposition of the notes. A U.S. Holder will be subject to backup withholding on these payments if the U.S. Holder fails to provide its taxpayer identification number to the paying agent and comply with certain certification procedures or otherwise establish an exemption from backup withholding. The amount of any backup withholding from a payment to a U.S. Holder will be

allowed as a credit against the U.S. Holder’s U.S. federal income tax liability and may entitle the U.S. Holder to a refund, provided that the required information is timely furnished to the IRS.

As used herein, the term “Non-U.S. Holder” means a beneficial owner of a note that is, for U.S. federal income tax purposes:

“Non-U.S. Holder” does not include a nonresident alien individual present in the United States for 183 days or more in the taxable year of disposition of the notes. Such a holder is urged to consult his or her own tax advisor regarding the U.S. federal income tax consequences of the sale, exchange or other disposition of the notes.

Payments on the Notes. Subject to the discussion below concerning backup withholding, payments of principal, interest (including original issue discount, if any) and premium on the notes by Equinix or any paying agent to any Non-U.S. Holder will not be subject to U.S. federal withholding tax, provided that, in the case of interest (including original issue discount, if any),

If a Non-U.S. Holder of a note is engaged in a trade or business in the United States, and if interest (including original issue discount, if any) on the note is effectively connected with the conduct of this trade or business, the Non-U.S. Holder, although exempt from the withholding tax discussed in the preceding paragraph, will generally be taxed in the same manner as a U.S. Holder (see “Tax Consequences to U.S. Holders” above), except that the Non-U.S. Holder will be required to provide a properly executed IRS Form W-8ECI in order to claim an exemption from the withholding tax discussed in the preceding paragraph. Holders are urged to consult their own tax advisors regarding whether an applicable income tax treaty provides for a different result and regarding other U.S. tax consequences of the ownership and disposition of notes including the possible imposition of a branch profits tax at a rate of 30% (or a lower treaty rate) on its effectively connected earnings and profits attributable to its notes.

Sale, Exchange or Other Disposition of Notes. Subject to the discussion below concerning backup withholding, a Non-U.S. Holder generally will not be subject to U.S. federal income tax on gain recognized on a sale or other disposition of notes (other than with respect to amounts attributable to accrued interest (including original issue discount) which will be subject to tax in the manner described above), unless the gain is effectively connected with a trade or business of the Non-U.S. Holder in the United States, subject to an applicable income tax treaty providing otherwise.

If a Non-U.S. Holder is engaged in a trade or business in the United States and gain recognized by the Non-U.S. Holder on a sale or other disposition of notes is effectively connected

with a conduct of such trade or business, the Non-U.S. Holder will generally be taxed in the same manner as a U.S. Holder (see “Tax Consequences to U.S. Holders” above), subject to an applicable income tax treaty providing otherwise. Non-U.S. Holders whose gain from dispositions of notes may be effectively connected with a conduct of a trade or business in the United States are urged to consult their own tax advisors with respect to the U.S. tax consequences of the ownership and disposition of notes, including the possible imposition of an additional branch profits tax imposed at a rate of 30% (or a lower treaty rate).

Backup Withholding and Information Reporting. Information returns will be filed with the IRS in connection with payments on the notes (including accruals of original issue discount, if any). Unless the Non-U.S. Holder complies with certification procedures to establish that it is not a United States person, information returns may be filed with the IRS in connection with the proceeds from a sale or other disposition of the notes and the Non-U.S. Holder may be subject to backup withholding on payments on the notes or on the proceeds from a sale or other disposition of the notes. Compliance with the certification procedures required to claim the exemption from withholding tax on interest described above will satisfy the certification requirements necessary to avoid backup withholding as well. The amount of any backup withholding from a payment to a Non-U.S. Holder will be allowed as a credit against the Non-U.S. Holder’s U.S. federal income tax liability and may entitle the Non-U.S. Holder to a refund, provided that the required information is timely furnished to the IRS.

Subject to the terms and conditions in the underwriting agreement between us and the underwriters, we have agreed to sell to each underwriter, and each underwriter has agreed to purchase from us, the principal amount of notes set forth opposite that underwriter’s name:

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

The underwriters initially propose to offer the notes to the public at the public offering price that appears on the cover page of this prospectus. The underwriters may offer the notes to selected dealers at the public offering price minus a concession of up to % of the principal amount. In addition, the underwriters may allow, and those selected dealers may reallow, a concession of up to % of the principal amount to certain other dealers. After the initial offering, the underwriters may change the public offering price and any other selling terms. The underwriters may offer and sell notes through certain of their affiliates.

The following table shows the underwriting discounts and commissions to be paid by us to the underwriters in connection with this offering (expressed as a percentage of the principal amount of the notes).

We estimate that the expenses for this offering payable by us (other than discounts and commissions set forth in the table above) will be approximately $500,000.

The notes are new issues of securities with no established trading market. We do not intend to apply for the notes to be listed on any securities exchange or to arrange for the notes to be

quoted on any quotation system. The underwriters have advised us that they intend to make a market in the notes, but they are not obligated to do so and they may discontinue any market making at any time in their sole discretion. Accordingly, we cannot assure you that a liquid trading market will develop for the notes, that you will be able to sell your notes at a particular time or that the prices that you receive when you sell will be favorable.

In relation to each Member State of the European Economic Area which has implemented the Prospectus Directive (each, a “Relevant Member State”), each underwriter has represented and agreed that with effect from and including the date on which the Prospectus Directive is implemented in that Relevant Member State (the “Relevant Implementation Date”) it has not made and will not make an offer of our securities which are the subject of this prospectus to the public in that Relevant Member State other than:

provided that no such offer of notes shall require us or any underwriter to publish a prospectus pursuant to Article 3 of the Prospectus Directive.

For the purposes of this provision, the expression “an offer of securities to the public” in relation to any notes in any Relevant Member State means the communication in any form and by any means of sufficient information on the terms of the offer and the securities to be offered so as to enable an investor to decide to purchase or subscribe for the securities, as the same may be varied in that Member State by any measure implementing the Prospectus Directive in that Member State, the expression “Prospectus Directive” means Directive 2003/71/EC (and amendments thereto, including the 2010 PD Amending Directive, to the extent implemented in the Relevant Member State), and includes any relevant implementing measure in the Relevant Member State and the expression “2010 PD Amending Directive” means Directive 2010/73/EU.

We have not authorized and do not authorize the making of any offer of notes through any financial intermediary on our behalf, other than offers made by the underwriters with a view to the final placement of the notes as contemplated in this prospectus. Accordingly, no purchaser of the notes, other than the underwriters, is authorized to make any further offer of the notes on behalf of us or the underwriters.

This prospectus is for distribution only to persons who (i) have professional experience in matters relating to investments falling within Article 19(5) of the Financial Services and Markets Act 2000 (Financial Promotion) Order 2005 (as amended, the “Financial Promotion Order”), (ii) are persons falling within Article 49(2)(a) to (d) (“high net worth companies, unincorporated associations etc”) of the Financial Promotion Order, (iii) are outside the United Kingdom, or (iv) are persons to whom an invitation or inducement to engage in investment activity (within the meaning of section 21 of the Financial Services and Markets Act 2000) in connection with the issue or sale of the notes may otherwise lawfully be communicated or caused to be communicated (all such persons together being referred to as “relevant persons”). This prospectus is directed only at relevant persons and must not be acted on or relied on by persons who are not relevant persons. Any investment or investment activity to which this prospectus relates is available only to relevant persons and will be engaged in only with relevant persons. Recipients of this prospectus are not permitted to transmit it to any other person. The notes are not being offered to the public in the United Kingdom.

In connection with this offering of the notes, the underwriters may engage in overallotments, stabilizing transactions and syndicate covering transactions in accordance with Regulation M under the Securities Exchange Act of 1934, or the Exchange Act. Overallotment involves sales in excess of the aggregate principal amount of notes offered pursuant to this prospectus, which creates a syndicate short position for the underwriters. Stabilizing transactions involve bids to purchase the notes in the open market for the purpose of pegging, fixing or maintaining the price of the notes. Syndicate covering transactions involve purchases of the notes in the open market after the distribution has been completed in order to cover short positions. Any of these activities may cause the market prices of the notes to be higher than they would otherwise be in the absence of those transactions. The underwriters are not required to engage in any of these activities, and may end any of them at any time.

Certain of the underwriters and their affiliates have performed commercial banking, investment banking and advisory services for us from time to time for which they have received customary fees and reimbursement of expenses. Certain affiliates of the underwriters act as lenders and/or agents under our credit facilities. The underwriters may, from time to time, engage in transactions with and perform services for us in the ordinary course of their business for which they may receive customary fees and reimbursement of expenses. Certain of the underwriters or their affiliates may be holders of our 2.50% convertible subordinated notes due 2012. We may use the net proceeds of this offering to repay the 2.50% convertible subordinated notes due 2012 upon maturity. Certain of the underwriters or their affiliates are customers of ours and engage in transactions with us or our affiliates in the ordinary course of business. Certain of the underwriters or their affiliates that have a lending relationship with us routinely hedge their credit exposure to us consistent with their customary risk management policies. Typically, such underwriters and their affiliates would hedge such exposure by entering into transactions which consist of either the purchase of credit default swaps or the creation of short positions in our securities, including potentially the notes offered hereby. Any such short positions could adversely affect future trading prices of the notes offered hereby.

We expect that the delivery of the notes will be made against payment therefor on or about , 2011, which will be the fifth business day following the date of pricing of the notes (such settlement cycle being herein referred to as “T+5”). Under Rule 15c6-1 under the Exchange Act, trades in the secondary market generally are required to settle in three business days, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who

wish to trade notes on the date of pricing will be required, by virtue of the fact that the notes initially will settle T+5, to specify an alternative settlement cycle at the time of any such trade to prevent a failed settlement. Purchasers of notes who wish to trade notes on the date of pricing should consult their advisor.

The legality of the notes offered hereby will be passed upon for us by Davis Polk & Wardwell LLP, Menlo Park, California. Certain legal matters will be passed upon for the underwriters by Cahill Gordon & Reindel LLP, New York, New York.

The financial statements as of December 31, 2010 and December 31, 2009 and for each of the three years in the period ended December 31, 2010 and management’s assessment of the effectiveness of internal control over financial reporting (which is included in Management’s Report on Internal Control over Financial Reporting) as of December 31, 2010 incorporated by reference in this prospectus have been so included in reliance on the report of PricewaterhouseCoopers LLP, an independent registered public accounting firm, given on the authority of said firm as experts in auditing and accounting.

The following table sets forth all expenses, other than the underwriting discounts and commissions, payable by the Registrant in connection with the sale of the securities being registered. All the amounts shown are estimates except for the registration fee.

Section 145 of the Delaware General Corporation Law authorizes a court to award or a corporation’s board of directors to grant indemnification to directors and officers in terms sufficiently broad to permit such indemnification under certain circumstances for liabilities (including reimbursement for expenses incurred) arising under the Securities Act of 1933, as amended (the “Act”). Article VI of the Registrant’s Amended and Restated Bylaws provides for mandatory indemnification of its directors and officers and those serving at the Registrant’s request as directors, officers, employees or agents of other organizations to the maximum extent permitted by the Delaware General Corporation Law. The Registrant’s Amended and Restated Certificate of Incorporation provides that, pursuant to Delaware law, its directors shall not be liable for monetary damages for breach of the directors’ fiduciary duty as directors to the Registrant and its stockholders. This provision in the Amended and Restated Certificate of Incorporation does not eliminate the directors’ fiduciary duty, and in appropriate circumstances equitable remedies such as injunctive or other forms of non-monetary relief will remain available under Delaware law. In addition, each director will continue to be subject to liability for breach of the director’s duty of loyalty to the Registrant for acts or omissions not in good faith or involving intentional misconduct or knowing violations of law, for actions leading to improper personal benefit to the director, and for payment of dividends or approval of stock repurchases or redemptions that are unlawful under Delaware law. The provision also does not affect a director’s responsibilities under any other law, such as the federal securities laws or state or federal environmental laws. The Registrant has entered into indemnification agreements with its officers and directors. The indemnification agreements provide the Registrant’s officers and directors with further indemnification to the maximum extent permitted by the Delaware General Corporation Law. The Registrant maintains liability insurance for its directors and officers.

1. To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(i) To include any prospectus required by section 10(a)(3) of the Securities Act of 1933;

(ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement.

(iii) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;

Provided, however, that paragraphs (1)(i), (1)(ii) and (1)(iii) of this section do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the registrant pursuant to section 13 or section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement, or contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration statement.

2. That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

3. To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

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

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

(i) Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;

(ii) Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;

(iii) The portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and

(iv) Any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

5. That, for the purpose of determining liability under the Securities Act of 1933 to any purchaser:

(i) Each prospectus filed by the registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and

(ii) Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5), or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii), or (x) for the purpose of providing the information required by section 10(a) of the Securities Act of 1933 shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which that prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date.

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

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

8. The undersigned registrant hereby undertakes to file an application for the purpose of determining the eligibility of the trustee to act under subsection (a) of section 310 of the Trust Indenture Act (“Act”) in accordance with the rules and regulations prescribed by the Commission under section 305(b)2 of the Act.

Pursuant to the requirements of the Securities Act of 1933, the registrant certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form S-3 and has duly caused this Registration Statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of Redwood City, State of California, on this 6th day of July, 2011.

KNOW ALL PERSONS BY THESE PRESENTS, that each individual whose signature appears below constitutes and appoints Stephen M. Smith and Keith D. Taylor, and each of them, his true and lawful attorneys-in-fact and agents with full power of substitution, for him and in his name, place and stead, in any and all capacities, to sign any and all amendments (including post-effective amendments) to this Registration Statement, and to sign any registration statement for the same offering covered by this Registration Statement that is to be effective on filing pursuant to Rule 462(b) promulgated under the Securities Act of 1933, and all post-effective amendments thereto, and to file the same, with all exhibits thereto and all documents in connection therewith, with the Securities and Exchange Commission, granting unto said attorneys-in-fact and agents, and each of them, full power and authority to do and perform each and every act and thing requisite and necessary to be done in and about the premises, as fully to all intents and purposes as he might or could do in person, hereby ratifying and confirming all that said attorneys-in-fact and agents or any of them, or his or their substitute or substitutes, may lawfully do or cause to be done by virtue hereof.
