 ABOUT THIS PROSPECTUS SUPPLEMENT
This document consists of two parts. The first part is this prospectus supplement, which describes the specific terms of this offering. The second part is the accompanying prospectus, which describes more general information, some of which may not apply to this offering.

Ratio of Earnings to Fixed Charges
The following table sets forth our ratio of earnings to fixed charges on a historical basis for each of the periods indicated. You should read these ratios in connection with our consolidated financial statements, including the notes to those statements, incorporated by reference in this prospectus supplement.

 	  	Fiscal Year Ended December 31,	 	
 	  	2015	 	  	2014	 	  	2013	 	  	2012	 	  	2011	 	
Ratio of earnings to fixed charges	  	 	9.6x	  	  	 	—   (1)	  	  	 	7.8x	  	  	 	4.6x	  	  	 	9.2x	  	

(1)	The pre-tax losses from continuing operations for the fiscal year ended December 31, 2014 were not sufficient to cover fixed charges by a total of approximately $88.5 million.	
The ratio of earnings to fixed charges has been computed on a consolidated basis. “Earnings” consist of consolidated net income before income taxes plus fixed charges, net of capitalized interest, plus amortization of capitalized interest, reduced by the non-controlling interest in pre-tax income of subsidiaries that have not incurred fixed charges. “Fixed charges” consist of interest expense, capitalized interest, and amortized premiums, discounts and capitalized expenses related to indebtedness as well as a portion of rental expense estimated to represent interest.
As of the date of this prospectus supplement, we have not previously paid dividends on any shares of preferred stock, and consequently, our ratio of earnings to preferred share dividends and ratio of earnings to fixed charges would be identical.

 RISK FACTORS
An investment in the notes involves certain risks. You should carefully consider the risks described below, as well as the other information included or incorporated by reference in this prospectus supplement and the accompanying prospectus, before making an investment decision. Our business, financial condition or results of operations could be materially adversely affected by any of these risks. This prospectus supplement also contains forward-looking statements that involve risks and uncertainties. Our actual results could differ materially from those anticipated in these forward-looking statements as a result of certain factors, including the risks faced by us described below and elsewhere in this prospectus supplement and the accompanying prospectus.
Risks Relating to our Company and Business
Our quarterly results are unpredictable and subject to substantial fluctuations; as a result, we may fail to meet the expectations of securities analysts and investors, which could adversely affect the trading price of our common stock.
Our revenues and operating results may vary significantly from quarter-to-quarter due to a number of factors, many of which are outside of our control and any of which may cause our stock price to fluctuate.
The factors that may cause our quarterly results to vary quarter by quarter and be unpredictable include, but are not limited to: limited visibility into customer spending plans, changes in the mix of products and services sold, changes in the mix of geographies in which our products and services are sold, changing market and economic conditions, current and potential customer, partner and supplier consolidation and concentration, competition, long sales and implementation cycles, unpredictable ordering patterns, changes in the amount and frequency of share repurchases or dividends, regional economic and political conditions, and seasonality. For example, we, and many companies in our industry, experience adverse seasonal fluctuations in customer spending, particularly in the first quarter. Furthermore, market trends, competitive pressures, commoditization of products, seasonal rebates, increased component or shipping costs, issues with product quality, regulatory impacts and other factors may result in reductions in revenue or pressure on gross margins of certain segments in a given period, which may necessitate adjustments to our operations. Such adjustments may be difficult or impossible to execute in the short or medium term.
As a result of these factors, as well as other variables affecting our operating results, we believe that quarter-to-quarter comparisons of operating results are not necessarily a good indication of what our future performance will be. It is likely that in some quarters, our operating results will be below our guidance, our long-term financial model or the expectations of securities analysts or investors, in which case the price of our common stock may decline. Such a decline could occur, and has occurred in the past, even when we have met our publicly stated revenues and/or earnings guidance.
A limited number of our customers comprise a significant portion of our revenues and there is an ongoing trend toward consolidation in the industry in which our customers and partners operate. Any decrease in revenues from our customers or partners could have an adverse effect on our net revenues and operating results.
A substantial majority of our net revenues depend on sales to a limited number of customers and distribution partners, particularly in our service provider market. Changes in the business requirements, vendor selection, project prioritization, financial prospects, capital resources, and expenditures, or purchasing behavior (including product mix purchased) of our key customers could significantly decrease our sales to such customers or could lead to delays or cancellations of planned purchases of our products or services, which increases the risk of quarterly fluctuations in our revenues and operating results. Any of these factors could adversely affect our business, financial condition, and results of operations.
 
S-7

Table of Contents
In addition, in recent years, there has been movement towards consolidation in the telecommunications industry (for example, Altice’s purchase of Portugal Telecom, Liberty Global’s proposed acquisition of Cable & Wireless Communications, AT&T’s acquisition of DirecTV, and Charter Communications, Inc.’s proposed acquisition of Time Warner Cable, Inc.) and that consolidation trend has continued. If our customers or partners are parties to consolidation transactions they may delay, suspend or indefinitely reduce or cancel their purchases of our products or other direct or indirect unforeseen consequences could harm our business, financial condition, and results of operations.
Fluctuating economic conditions make it difficult to predict revenues and gross margin for a particular period and a shortfall in revenues or increase in costs of production may harm our operating results.
Our revenues and gross margin depend significantly on general economic conditions and the demand for products in the markets in which we compete. Economic weakness or uncertainty, customer financial difficulties, and constrained spending on network expansion and enterprise infrastructure have in the past resulted in, and may in the future result in, decreased revenues and earnings. Such factors could make it difficult to accurately forecast sales and operating results and could negatively affect our ability to provide accurate forecasts to our contract manufacturers and manage our contract manufacturer relationships and other expenses. In addition, economic instability or uncertainty, as well as continued turmoil in the geopolitical environment in many parts of the world, have, and may continue to, put pressure on economic conditions, which has led and could lead, to reduced demand for our products, to delays or reductions in network expansions or infrastructure projects, and/or higher costs of production. More generally-speaking, economic weakness may also lead to longer collection cycles for payments due from our customers, an increase in customer bad debt, restructuring initiatives and associated expenses, and impairment of investments. Furthermore, instability in the global credit markets may adversely impact the ability of our customers to adequately fund their expected capital expenditures, which could lead to delays or cancellations of planned purchases of our products or services. Our operating expenses are largely based on anticipated revenue trends and a high percentage of our expenses is, and will continue to be, fixed in the short and medium term. Therefore, fluctuations in revenue could cause significant variations in our operating results and operating margins from quarter to quarter.
Uncertainty about future economic conditions also makes it difficult to forecast operating results and to make decisions about future investments. Future or continued economic weakness, failure of our customers and markets to recover from such weakness, customer financial difficulties, increases in costs of production, and reductions in spending on network maintenance and expansion could result in price concessions in certain markets or have a material adverse effect on demand for our products and consequently on our business, financial condition, and results of operations.
Our success depends upon our ability to effectively plan and manage our resources and restructure our business through rapidly fluctuating economic and market conditions, and such actions may have an adverse effect on our financial and operating results.
Our ability to successfully offer our products and services in a rapidly evolving market requires an effective planning, forecasting, and management process to enable us to effectively scale and adjust our business in response to fluctuating market opportunities and conditions.
In periods of market expansion, we have increased investment in our business by, for example, increasing headcount and increasing our investment in R&D, sales and marketing, and other parts of our business. Conversely, in 2014, to refocus the Company’s strategy, optimize its structure and improve operational efficiencies, we implemented a new strategic focus, realigned our organization into a One-Juniper structure, reduced our workforce, consolidated and closed facilities, made changes to enhance efficiency, improved cost management measures and instituted a new capital allocation plan. In connection with our cost management measures, we implemented a substantial cost reduction plan accomplished through various restructuring activities across R&D, sales and marketing and general and administrative. We recorded a goodwill impairment charge of

$850.0 million in the fourth quarter of 2014 due to the underperformance of our Security reporting unit and product rationalizations. Further strategy-related pivots could lead to delays in achieving revenue and profit forecasts and result in additional impairment. Some of our expenses are fixed costs that cannot be rapidly or easily adjusted in response to fluctuations in our business or numbers of employees. Rapid changes in the size, alignment or organization of our workforce, including sales account coverage, could adversely affect our ability to develop and deliver products and services as planned or impair our ability to realize our current or future business and financial objectives. Our ability to achieve the anticipated cost savings and other benefits from our restructuring initiatives within the expected time frame is subject to many estimates and assumptions. These estimates and assumptions are subject to significant economic, competitive and other uncertainties, some of which are beyond our control. If these estimates and assumptions are incorrect, if we are unsuccessful at implementing changes, or if other unforeseen events occur, our business and results of operations could be adversely affected.
We face intense competition that could reduce our revenues and adversely affect our business and financial results.
Competition is intense in the markets that we serve. The network equipment market has historically been dominated by Cisco, with competition coming from other companies such as Alcatel-Lucent, Arista, Brocade, HP, and Huawei. In the security market, we face intense competition from Cisco and Palo Alto Networks, as well as companies such as Check Point, F5 Networks, Fortinet, and HP. Further, a number of other small public and private companies have products or have announced plans for new products to address the same challenges and markets that our products address.
In addition, actual or speculated consolidation among competitors, or the acquisition by, or of, our partners and/or resellers by competitors can increase the competitive pressures faced by us as customers may delay spending decisions or not purchase our products at all. For example, in recent years, Nokia Corporation merged with Alcatel-Lucent, HP acquired Aruba Networks, and Cisco acquired OpenDNS and Sourcefire, Inc., which further consolidated our market. In addition, Dell announced a proposed acquisition of EMC, which we anticipate will further consolidate our market upon its consummation. A number of our competitors have substantially greater resources and can offer a wider range of products and services for the overall network equipment market than we do. In addition, some of our competitors have become more integrated, including through consolidation, and offer a broader range of products and services, which could make their solutions more attractive to our customers. Many of our competitors sell networking products as bundled solutions with other IT products, such as computer and storage systems. If we are unable to compete successfully against existing and future competitors on the basis of product offerings or price, we could experience a loss in market share and revenues and/or be required to reduce prices, which could reduce our gross margins, and which could materially and adversely affect our business, financial condition, and results of operations. Our partners and resellers generally sell or resell competing products on a non-exclusive basis and consolidation could delay spending or require us to increase discounts to compete, which could also adversely affect our business.
We expect our gross margins and operating margins to vary over time, and the level of gross margins achieved by us in recent years may not be sustainable.
We expect our product and service gross margins to vary from quarter-to-quarter, and the gross margins we have achieved in recent years may not be sustainable and may be adversely affected in the future by numerous factors, including customer, product and geographic mix shifts, increased price competition in one or more of the markets in which we compete, currency fluctuations that impact our costs or the cost of our products and services to our customers, increases in material, labor, or inventory carrying costs, excess product component or obsolescence charges from our contract manufacturers, increased costs due to changes in component pricing or charges incurred due to component holding periods if we do not accurately forecast product demand, warranty related issues, or our introduction of new products and enhancements or entry into new markets with different pricing and cost structures. For example, in fiscal year 2014, our margins declined compared to fiscal year 2013,

as a result of higher inventory charges resulting from product rationalizations and an industry-wide memory product quality defect for a component from a third party. We determine our operating expenses largely on the basis of anticipated revenues and a high percentage of our expenses are fixed in the short and medium term. As a result, a failure or delay in generating or recognizing revenue could cause significant variations in our operating results and operating margin from quarter-to-quarter. Failure to sustain or improve our gross margins reduces our profitability and may have a material adverse effect on our business and stock price.
Further, we will continue to remain diligent in our long-term financial objective to increase revenue and operating margins and manage our operating expenses as a percentage of revenue. We expect that our margins will vary with our ability to achieve these goals. We can provide no assurance that we will be able to achieve all of the goals of these plans or meet our announced expectations, in whole or in part, or that our plans will have the intended effect of improving our margins on the expected timeline, or at all.
Conversion of key internal systems and processes, particularly our ERP system, and problems with the design or implementation of these systems and processes could interfere with, and therefore harm, our business and operations.
We have underway a multi-phase project to convert certain key internal systems and processes, including our customer relationship management, or CRM, system and enterprise resource planning, or ERP, system. Since 2012, we have been implementing major changes to our ERP system, which activities we expect to continue into 2016. In the third quarter of 2014, we implemented the manufacturing, fulfillment, and inventory portion of this ERP project and were reliant upon a dual ERP systems until January 2016 when we moved to a single ERP System. In connection with the transfer to our new ERP system, we scheduled a shutdown of certain of our legacy ERP systems, which may impact our DSO and/or our cash collections in the first quarter of 2016. We are still early in the process of operating under our new ERP system and may need to resolve issues that arise in connection with this transition. We have invested, and will continue to invest, significant capital and human resources in the design and implementation of these systems and processes. Any problems, disruptions, delays or other issues in the design and implementation of the new systems or processes, particularly any that impact our operations, could adversely affect our ability to process customer orders, ship products, provide service and support to our customers, bill and track our customers, collect cash from our customers, maintain our DSO measure, fulfill contractual obligations, record and transfer information in a timely and accurate manner, recognize revenue, file SEC reports in a timely manner, or otherwise run our business. Even if we do not encounter these adverse effects, as noted above, the design and implementation of these new systems and processes may be much more costly than we anticipated and in the event of lengthy project delays, we may experience issues with retention of the implementation team. If we are unable to successfully design and implement these new systems and processes as planned, or if the implementation of these systems and processes is more lengthy or costly than anticipated, our business, financial condition, and results of operations could be negatively impacted.
The long sales and implementation cycles for our products, as well as our expectation that some customers will sporadically place large orders with short lead times, may cause our revenues and operating results to vary significantly from quarter-to-quarter.
A customer’s decision to purchase certain of our products, particularly new products, involves a significant commitment of its resources and a lengthy evaluation and product qualification process. As a result, the sales cycle may be lengthy. In particular, customers making critical decisions regarding the design and implementation of large network deployments may engage in very lengthy procurement processes that may delay or impact expected future orders. Throughout the sales cycle, we may spend considerable time educating and providing information to prospective customers regarding the use and benefits of our products. Even after making the decision to purchase, customers may deploy our products slowly and deliberately. Timing of deployment can vary widely and depends on the skill set of the customer, the size of the network deployment, the complexity of the customer’s network environment, and the degree of hardware and operating system configuration necessary

to deploy the products. Customers with large networks usually expand their networks in large increments on a periodic basis. Accordingly, we may receive purchase orders for significant dollar amounts on an irregular basis. These long cycles, as well as our expectation that customers will tend to sporadically place large orders with short lead times, both of which may be exacerbated by the impact of continued global economic weakness, may cause revenues and operating results to vary significantly and unexpectedly from quarter-to-quarter.
The timing of product orders and/or our reliance on revenue from sales of software or subscription and support and maintenance services may cause us to recognize revenue in a different period than the one in which a transaction takes place. This may make it difficult for investors to observe quarterly trends and may cause significant variations in our operating results and operating margin on a quarterly basis.
Generally, our network equipment products are stocked only in limited quantities by our distributors and resellers due to the cost, complexity and custom nature of configurations required by our customers; we generally build such products as orders are received. The volume of orders received late in any given fiscal quarter remains unpredictable. If orders for certain products are received late in any quarter, we may not be able to recognize revenue for these orders in the same period, which could adversely affect our ability to meet our expected revenues for such quarter.
In addition, services revenue accounts for a significant portion of our revenue, comprising 27%, 26%, and 25% of total revenue in fiscal year 2015, 2014, and 2013, respectively. Sales of new or renewal support and maintenance contracts may decline and/or fluctuate as a result of a number of factors, including end-customers’ level of satisfaction with our products and services, the prices of our products and services, the prices of products and services offered by our competitors, and reductions in our end-customers’ spending levels. We recognize support and maintenance revenue periodically over the term of the relevant service period.
The introduction of new software products is part of our intended strategy to expand our software business, and software revenues may be recognized periodically over the term of the relevant use period or subscription period. As a result, much of the software, subscription and support and maintenance revenue we report each fiscal quarter is the recognition of deferred revenue from software, subscription and support and maintenance contracts entered into during previous fiscal quarters. Consequently, a decline in new or renewed contracts in any one fiscal quarter will not be fully or immediately reflected in revenue in that fiscal quarter but will negatively affect our revenue in future fiscal quarters. Accordingly, the effect of significant downturns in new or renewed sales of our software, subscriptions or support and maintenance is not reflected in full in our operating results until future periods. Also, it is difficult for us to rapidly increase our software or services revenue through additional software or services sales in any period, as revenue from new and renewal software, subscription and support and maintenance contracts must be recognized over the applicable service period.
Additionally, we determine our operating expenses largely on the basis of anticipated revenues and a high percentage of our expenses are fixed in the short and medium term. As a result, a failure or delay in generating or recognizing revenue could cause significant variations in our operating results and operating margin from quarter-to-quarter.
We are dependent on sole source and limited source suppliers for several key components, which makes us susceptible to shortages or price fluctuations in our supply chain, and we may face increased challenges in supply chain management in the future.
We rely on single or limited sources of certain of our components. During periods of high demand for electronic products, component shortages are possible, and the predictability of the availability of such components may be limited. Any future spike in growth in our business, or more likely in IT spending and the economy in general is likely to create greater short-term pressures on us and our suppliers to accurately forecast overall component demand and to establish optimal component inventories. If shortages or delays persist, the price of these components may increase, or the components may not be available at all. We may not be able to
 
S-11

secure enough components at reasonable prices or of acceptable quality to build new products in a timely manner, and our revenues and gross margins could suffer until other sources can be developed. For example, from time to time, we have experienced component shortages that resulted in delays of product shipments. We currently purchase numerous key components, including ASICs and other semiconductor chips, from single or limited sources and many of our component suppliers are concentrated in China. In addition, there has been consolidation among certain suppliers of our components. For example, GLOBALFOUNDRIES recently acquired IBM’s semiconductor manufacturing business, Avago Technologies Limited recently acquired Broadcom Corporation and Intel Corporation recently acquired Altera Corporation. Consolidation among suppliers can result in the reduction of the number of independent suppliers of components available to us, which could negatively impact our ability to access certain component parts or the prices we have to pay for such parts. Any disruptions to our supply chain could decrease our sales, earnings, and liquidity or otherwise adversely affect our business and result in increased costs. Such a disruption could occur as a result of any number of events, including, but not limited to, increases in wages that drive up prices, the imposition of regulations, quotas or embargoes on key components, labor stoppages, transportation failures affecting the supply and shipment of materials and finished goods, the unavailability of raw materials, severe weather conditions, natural disasters, civil unrest, geopolitical developments, war or terrorism and disruptions in utility and other services.
The development of alternate sources for key components is time-consuming, difficult, and costly. In addition, the lead times associated with certain components are lengthy and preclude rapid changes in quantities and delivery schedules. Also, long-term supply and maintenance obligations to customers increase the duration for which specific components are required, which may further increase the risk of component shortages or the cost of carrying inventory. In the event of a component shortage or supply interruption from these suppliers, we may not be able to develop alternate or second sources in a timely manner. If we are unable to buy these components in quantities sufficient to meet our requirements on a timely basis, we will not be able to deliver products and services to our customers, which would seriously affect present and future sales, which would, in turn, adversely affect our business, financial condition, and results of operations.
In addition, the development, licensing, or acquisition of new products in the future may increase the complexity of supply chain management. Failure to effectively manage the supply of key components and products would adversely affect our business.
We rely on value-added and other resellers, as well as distribution partners, to sell our products, and disruptions to, or our failure to effectively develop and manage, our distribution channel and the processes and procedures that support it could adversely affect our ability to generate revenues from the sale of our products.
Our future success is highly dependent upon establishing and maintaining successful relationships with a variety of value-added and other reseller and distribution partners, including our worldwide strategic partners such as Ericsson, IBM, Nokia Solutions and Networks O.Y., Dimension Data and NEC Corporation. The majority of our revenues are derived through value-added resellers and distributors, most of which also sell our competitors’ products, and some of which sell their own competing products. Our revenues depend in part on the performance of these partners. The loss of or reduction in sales to our resellers or distributors could materially reduce our revenues. For example, in 2011 and 2012, one of our OEM partners, Dell, acquired Force10 and SonicWall, both competitors of ours. As a result, Dell became increasingly competitive in certain areas, their resale of our products declined, and we ultimately terminated our OEM relationship with Dell. In addition, Nokia Corporation merged with Alcatel-Lucent, a competitor of ours, and Cisco recently announced a partnership with Ericsson, which is one of our existing partners. Our competitors may in some cases be effective in leveraging their market share positions or in providing incentives to current or potential resellers and distributors to favor their products or to prevent or reduce sales of our products. If we fail to develop and maintain relationships with our partners, fail to develop new relationships with value-added resellers and distributors in new markets, fail to expand the number of distributors and resellers in existing markets, fail to manage, train or motivate existing value-added resellers and distributors effectively, determine that we cannot continue to do business with these

partners for any reason or if these partners are not successful in their sales efforts, sales of our products may decrease, and our business, financial condition, and results of operations would suffer.
In addition, we recognize a portion of our revenues based on a sell-through model using information provided by our distributors. If those distributors provide us with inaccurate or untimely information, the amount or timing of our revenues could be adversely impacted.
Further, in order to develop and expand our distribution channel, we must continue to offer attractive channel programs to potential partners and scale and improve our processes and procedures that support the channel. As a result, our programs, processes and procedures may become increasingly complex and inherently difficult to manage. We have previously entered into OEM agreements with partners pursuant to which they rebrand and resell our products as part of their product portfolios. These types of relationships are complex and require additional processes and procedures that may be challenging and costly to implement, maintain and manage. Our failure to successfully manage and develop our distribution channel and the programs, processes and procedures that support it could adversely affect our ability to generate revenues from the sale of our products. We also depend on our global channel partners to comply with applicable legal and regulatory requirements. To the extent that they fail to do so, that could have a material adverse effect on our business, operating results, and financial condition.
System security risks, data protection breaches, and cyber-attacks could compromise our proprietary information, disrupt our internal operations and harm public perception of our products, which could cause our business and reputation to suffer and adversely affect our stock price.
In the ordinary course of business, we store sensitive data, including intellectual property, personal data, our proprietary business information and that of our customers, suppliers and business partners on our networks. In addition, we also store sensitive data through cloud-based services that may be hosted by third parties and in data center infrastructure maintained by third parties. The secure maintenance of this information is critical to our operations and business strategy. The growing cyber risk environment means that individuals, companies, and organizations of all sizes including us, are increasingly subject to the threat of intrusions on their networks and systems by a wide range of actors on an ongoing and regular basis. Despite our security measures, and those of our third-party vendors, our information technology and infrastructure may be vulnerable to penetration or attacks by computer programmers, hackers, or sophisticated nation-state and nation-state supported actors or breached due to employee error, malfeasance or other disruptions. If any breach compromises our networks, creates system disruptions or slowdowns or exploits security vulnerabilities of our products, the information stored on our networks could be accessed and modified, publicly disclosed, lost or stolen, and we may be subject to liability to our customers, suppliers, business partners and others, and suffer reputational and financial harm. In addition, sophisticated hardware and operating system software and applications that we produce or procure from third parties may contain defects in design or manufacture, including “bugs” and other problems that could unexpectedly interfere with the operation of our networks. This can be true even for “legacy” products that have been determined to have reached an end of life engineering status but will continue to operate for a limited amount of time.
For example, in December 2015, we disclosed that we identified unauthorized code in our ScreenOS security system that could allow a knowledgeable attacker to gain administrative access to NetScreen devices and to decrypt VPN connections. Following the identification of the ScreenOS vulnerabilities, we launched an investigation into the matter, developed patched releases for the latest versions of ScreenOS and notified customers, all of which required significant time and attention from management and our employees. We also announced that we are making additional changes to ScreenOS in response to our additional analysis and the investigation is ongoing. At this time, we do not have an estimate of third party costs related to the ScreenOS matter that could result from any third party claims brought against us, including, for example, indemnification for damages our customers may incur or actions instituted by governmental or regulatory entities that could result in fines or other penalties. Costs related to the ScreenOS matter, including the costs to resolve third party claims, costs relating to the investigation and the time and resources required to develop patched releases and further modify the products, may be material.

Table of Contents
As a result of the ScreenOS matter, or any other actual or perceived breach of network security that occurs in our network or in the network of a customer of our products, regardless of whether the breach is attributable to our products, the market perception of the effectiveness of our products and our overall reputation could be harmed. Because the techniques used by attackers, many of whom are highly sophisticated and well-funded, to access or sabotage networks change frequently and generally are not recognized until after they are used, we may be unable to anticipate or immediately detect these techniques or the vulnerabilities they have caused. This could impede our sales, manufacturing, distribution or other critical functions, which could have an adverse impact on our financial results. The economic costs to us to eliminate or alleviate cyber or other security problems, bugs, viruses, worms, malicious software systems and security vulnerabilities, including the ScreenOS matter, could be significant and may be difficult to anticipate or measure because the damage may differ based on the identity and motive of the attacker, which are often difficult to pinpoint. Additionally, we could be subject to regulatory investigations, potential fines and litigation in connection with a security breach or related issue and be liable to third parties for these types of breaches.
Our ability to process orders and ship products in a timely manner is dependent in part on our business systems and performance of the systems and processes of third parties such as our contract manufacturers, suppliers, data center providers or other partners, as well as the interfaces between our systems and the systems of such third parties. If our systems, the systems and processes of those third parties, or the interfaces between them experience delays or fail, our business processes and our ability to build and ship products could be impacted, and our financial results could be harmed.
Some of our business processes depend upon our information technology, or IT, systems, the systems and processes of third parties, and the interfaces of our systems with the systems of third parties. For example, our order entry system feeds information into the systems of our contract manufacturers, which enables them to build and ship our products. If those systems fail or are interrupted, our processes may function at a diminished level or not at all. This could negatively impact our ability to ship products or otherwise operate our business, and our financial results could be harmed. For example, although it did not adversely affect our shipments, an earthquake in late December of 2006 disrupted our communications with China, where a significant part of our manufacturing occurs. In addition, as discussed earlier in this Risk Factors section, beginning in 2012 and continuing into 2016, we have been implementing major changes to our ERP system. Any failure of the new system or interruptions during the implementation process may impair communications with our manufacturers, and, therefore, adversely affect our ability to build and ship our products.
We are also in the process of further consolidating our on-site data centers to the cloud and to off-site facilities that are hosted and controlled by third-parties. These cloud providers and off-site facilities are vulnerable to damage, interruption or performance problems from earthquakes, hurricanes, floods, fires, power loss, telecommunications failures, equipment failure, adverse events caused by operator error and similar events. In addition, because we lease our cloud storage space and off-site data center facilities, we cannot be assured that we will be able to expand our data center infrastructure to meet user demand in a timely manner, or on favorable economic terms. If we have issues receiving and processing data, this may delay our ability to provide products and services to our customers and damage our business. We also rely upon the performance of the systems and processes of our contract manufacturers to build and ship our products. If those systems and processes experience interruption or delay, our ability to build and ship our products in a timely manner may be harmed. For example, we have experienced instances where our contract manufacturers were not able to ship products in the time periods expected by us, which prevented us from meeting our commitments to our customers. If we are not able to ship our products or if product shipments are delayed, our ability to recognize revenue in a timely manner for those products would be affected and our financial results could be harmed.
Telecommunications, cable and cloud service provider companies and our other large customers generally require onerous terms and conditions in our contracts with them. As we seek to sell more products to such customers, we may be required to agree to terms and conditions that could have an adverse effect on our business or ability to recognize revenues.
 
S-14

Table of Contents
Telecommunications, cable and cloud service provider companies, which comprise a significant portion of our customer base, and other large companies, generally have greater purchasing power than smaller entities and, accordingly, often request and receive more favorable terms from suppliers. For example, our customers, France Telecom-Orange and Deutsche Telekom AG have formed a company for the purpose of purchasing products from, and negotiating more favorable contractual terms with, suppliers. As we seek to sell more products to this class of customer, we may be required to agree to such terms and conditions, which may include terms that affect the timing of our ability to recognize revenue, increase our costs and have an adverse effect on our business, financial condition, and results of operations. Consolidation among such large customers can further increase their buying power and ability to require onerous terms.
In addition, service providers have purchased products from other vendors who promised but failed to deliver certain functionality and/or had products that caused problems or outages in the networks of these customers. As a result, these customers may request additional features from us and require substantial penalties for failure to deliver such features or may require substantial penalties for any network outages that may be caused by our products. These additional requests and penalties, if we are required to agree to them, may require us to defer revenue recognition from such sales, which may negatively affect our business, financial condition and results of operations. In addition, increased patent litigation brought against customers by non-practicing entities in recent years, may result, and in some cases has resulted, in customers requesting or requiring vendors to absorb a portion of the costs of such litigation or providing broader indemnification for litigation, each of which could increase our expenses and negatively affect our business, financial condition and results of operations.
If we do not successfully anticipate technological shifts, market needs and opportunities, and develop products, product enhancements and business strategies that meet those technological shifts, needs and opportunities, or if those products are not made available or strategies are not executed in a timely manner or do not gain market acceptance, we may not be able to compete effectively and our ability to generate revenues will suffer.
The markets for our products are characterized by rapid technological change, frequent new product introductions, changes in customer requirements, continued price pressures and a constantly evolving industry. We cannot guarantee that we will be able to anticipate future technological shifts, market needs and opportunities or be able to develop new products, product enhancements or business strategies to meet such technological shifts, needs or opportunities in a timely manner or at all. For example, the move from traditional network infrastructures towards software-defined networking, or SDN, has been receiving considerable attention. In our view, it will take several years to see the full impact of SDN, and we believe the successful products and solutions in this market will combine hardware and software elements. If we fail to anticipate market requirements or opportunities or fail to develop and introduce new products, product enhancements or business strategies to meet those requirements or opportunities in a timely manner, it could cause us to lose customers, and such failure could substantially decrease or delay market acceptance and sales of our present and future products and services, which would significantly harm our business, financial condition, and results of operations. Even if we are able to anticipate, develop, and commercially introduce new products, enhancements or business strategies, there can be no assurance that new products, enhancements or business strategies will achieve widespread market acceptance.
In the past two years, we have announced a number of new hardware and software products across routing, switching and security, including ACX5000 and ACX500 routers, QFX10000 line of spine switches, QFX5100, QFX5100-AA, QFX-PFA, SRX300, SRX1500, SRX5000 and SRX5800 Series Services Gateways, EX9200 and EX4600 Ethernet Switches, new MX Series line cards and routers (including the vMX 3D Universal Edge Router), new PTX Series line cards (powered by our ExpressPlus custom silicon), NorthStar Controller, Junos Fusion, Junos Fusion Provider Edge, Junos Fusion Data Center, Junos Fusion Enterprise, OCX1100, PTX1000, vSRX Virtual Firewall, Sky Advanced Threat Prevention, Spotlight Secure, Junos Space Security Director, Junos Space Virtual Director, Juniper Networks Contrail Networking and Cloud CPE solution and NFX250 network

services platform. The success of our new products depends on several factors, including, but not limited to, component costs, timely completion and introduction of these products, prompt resolution of any defects or bugs in these products, differentiation of new products from those of our competitors and market acceptance of these products.
The introduction of new software products is part of our intended strategy to expand our software business. We have also begun to disaggregate certain software from certain hardware products, such that customers would be able to purchase or license our hardware and software products independently, which we expect could in time enable our hardware to be deployed with third party networking applications and services and our software to be used with third party hardware. For example, we have developed a disaggregated version of our Junos software and recently introduced our QFX5200 series of switches, which runs our disaggregated Junos software. The success of our strategy to expand our software business, including our strategy to disaggregate software from certain hardware products, is subject to a number of risks and uncertainties, including:
 
 	•	 	the additional development efforts and costs required to create new software products and/or to make our disaggregated products compatible with multiple technologies;	
 
 	•	 	the possibility that our new software products or disaggregated products may not achieve widespread customer adoption;	
 
 	•	 	the potential that our strategy could erode our gross margins;	
 
 	•	 	the impact on our financial results of longer periods of revenue recognition and changes in tax treatment associated with software sales;	
 
 	•	 	the additional costs associated with regulatory compliance and changes we need to make to our distribution chain in connection with increased software sales;	
 
 	•	 	the ability of our disaggregated hardware and software products to operate independently and/or to integrate with current and future third party products; and	
 
 	•	 	the risk that issues with third party technologies used with our disaggregated products will be attributed to us.	
If any of our new products or business strategies do not gain market acceptance or meet our expectations for growth, our ability to meet future financial targets may be adversely affected and our competitive position and our business and financial results could be harmed.
We are a party to lawsuits, investigations, proceedings, and other disputes, which are costly to defend and, if determined adversely to us, could require us to pay fines or damages, undertake remedial measures or prevent us from taking certain actions, any or all of which could harm our business, results of operations, financial condition or cash flows.
We, and certain of our current and former officers and current and former members of our Board of Directors, have been or are subject to various lawsuits. We have been served with lawsuits related to employment matters, commercial transactions and patent infringement, as well as securities laws. As noted in Note 16, Commitments and Contingencies , in Notes to Consolidated Financial Statements of our Annual Report on Form 10-K for the year ended December 31, 2015, under the heading of “Legal Proceedings”, the U.S. Securities and Exchange Commission, or the SEC, and the U.S. Department of Justice, or the DOJ, are conducting investigations into possible violations by the Company of the U.S. Foreign Corrupt Practices Act, or the FCPA, in a number of countries. The investigations relate to whether the Company or any third party on behalf of the Company gave money or anything else of value to any government official in violation of the FCPA. The Company’s Audit Committee, with the assistance of independent advisors, has been investigating and conducting a thorough review of possible violations of the FCPA, and has made recommendations for remedial measures, including employee disciplinary actions in foreign jurisdictions, which the Company has implemented and

continues to implement. Litigation and investigations are inherently uncertain. We therefore cannot predict the duration, scope, outcome or consequences of litigation and government investigations. In connection with any government investigations, including those in which we are currently involved as described above, if the government takes action against us or we agree to settle the matter, we may be required to pay substantial fines and incur other sanctions, which may be material, and suffer reputational harm. The lawsuits and investigations are expensive and time-consuming to defend, settle, and/or resolve, and may require us to implement certain remedial measures that could prove costly or disruptive to our business and operations. The unfavorable resolution of one or more of these matters could have a material adverse effect on our business, results of operations, financial condition or cash flows.
We are a party to litigation and claims regarding intellectual property rights, resolution of which may be time - consuming and expensive, as well as require a significant amount of resources to prosecute, defend, or make our products non-infringing.
Our industry is characterized by the existence of a large number of patents and frequent claims and related litigation regarding patent and other intellectual property rights. We expect that infringement claims may increase as the number of products and competitors in our market increases and overlaps occur. Third parties have asserted and may in the future assert claims or initiate litigation related to patent, copyright, trademark, and other intellectual property rights to technologies and related standards that are relevant to our products. The asserted claims and/or initiated litigation may include claims against us or our manufacturers, suppliers, partners, or customers, alleging that our products or services infringe proprietary rights. In addition, increased patent litigation brought by non-practicing entities in recent years may result, and in some cases has resulted, in our customers requesting or requiring us to absorb a portion of the costs of such litigation or providing broader indemnification for litigation, each of which could increase our expenses and negatively affect our business, financial condition and results of operations. Regardless of the merit of these claims, they have been and can be time-consuming, result in costly litigation, and may require us to develop non-infringing technologies, enter into license agreements, or cease engaging in certain activities or offering certain products or services. Furthermore, because of the potential for high awards of damages or injunctive relief that are not necessarily predictable, even arguably unmeritorious claims may be settled for significant amounts of money. If any infringement or other intellectual property claim made against us or anyone we are required to indemnify by any third-party is successful, if we are required to settle litigation for significant amounts of money, if we fail to develop non-infringing technology or if we license required proprietary rights, our business, financial condition, and results of operations could be materially and adversely affected.
Regulation of industry in general and the telecommunications industry in particular could harm our operating results and future prospects.
We are subject to laws and regulations affecting the sale of our products in a number of areas. For example, some governments have regulations prohibiting government entities from purchasing security products that do not meet specified indigenous certification criteria, even though those criteria may be in conflict with accepted international standards. Other regulations that may negatively impact our business include country of origin regulations. These types of regulations are in effect or under consideration in several jurisdictions where we do business.
The Dodd-Frank Wall Street Reform and Consumer Protection Act includes disclosure requirements applicable to public companies regarding the use of “conflict minerals” mined from the Democratic Republic of Congo and adjoining countries, which we refer to collectively as the DRC, and procedures regarding a manufacturer’s efforts to prevent the sourcing of such “conflict minerals.” These minerals are present in our products. SEC rules implementing these requirements may have the effect of reducing the pool of suppliers who can supply DRC “conflict free” components and parts, and we may not be able to obtain DRC conflict free products or supplies in sufficient quantities for our operations. Since our supply chain is complex, we may face reputational challenges with our customers, stockholders and other stakeholders if we are unable to sufficiently verify the origins for the “conflict minerals” used in our products.

In addition, environmental laws and regulations relevant to electronic equipment manufacturing or operations, including laws and regulations governing the hazardous material content of our products and laws relating to the collection of and recycling of electrical and electronic equipment, may adversely impact our business and financial condition. These laws and regulations include, among others, the European Union, or EU, Restriction on the Use of Certain Hazardous Substances in Electrical and Electronic Equipment Directive, or RoHS. The EU RoHS and the similar laws of other jurisdictions limit the content of certain hazardous materials such as lead, mercury, and cadmium in the manufacture of electrical equipment, including our products. Currently, our products comply with the EU RoHS requirements. However, certain exemptions are scheduled to lapse in the future, including an exemption for lead in network infrastructure equipment upon which we and our competitors rely, and which is currently scheduled to expire in July 2016. The lapse of this exemption, further changes to this or other laws, or passage of similar laws in the EU or other jurisdictions, would require us to cease selling non-compliant products in the EU and to reengineer our products to use components compatible with these regulations. This reengineering and component substitution could result in additional costs to us, disrupt our operations or logistics, and result in an adverse impact on our operating results. In addition, in validating the compliance of our products with applicable hazardous materials restrictions, we rely substantially on affirmations by our component suppliers as to the compliance of their products with respect to those same restrictions. Failure by our component suppliers to furnish accurate and timely information could subject us to penalties or liability for violation of such hazardous materials restrictions, interrupt our supply of products to the EU, and result in our customers refusing or being unable to purchase our products. Additionally, the EU and a number of other countries have adopted regulations requiring producers of electrical and electronic equipment to assume certain responsibilities for collecting, treating, recycling and disposing of products when they have reached the end of their useful life. Finally, the EU REACH regulations regulate the handling of certain chemical substances that may be used in our products.
The traditional telecommunications industry is highly regulated, and our business and financial condition could be adversely affected by changes in regulations relating to the Internet telecommunications industry. Currently, there are few laws or regulations that apply directly to access to or commerce on IP networks, but future regulations could include sales taxes on products sold via the Internet and Internet service provider access charges. We could be adversely affected by regulation of IP networks and commerce in any country where we market equipment and services to service providers or cloud provider companies. Regulations governing the range of services and business models that can be offered by service providers or cloud provider companies could adversely affect those customers’ needs for products. For instance, the U.S. Federal Communications Commission has issued regulations governing aspects of fixed broadband networks and wireless networks. These regulations, which are being challenged in court, might impact service provider and cloud provider business models and, as such, providers’ needs for Internet telecommunications equipment and services. Also, many jurisdictions are evaluating or implementing regulations relating to cyber security, supply chain integrity, privacy and data protection, any of which can affect the market and requirements for networking and security equipment.
The adoption and implementation of additional regulations could reduce demand for our products, increase the cost of building and selling our products, result in product inventory write-offs, impact our ability to ship products into affected areas and recognize revenue in a timely manner, require us to spend significant time and expense to comply, and subject us to fines and civil or criminal sanctions or claims if we were to violate or become liable under such regulations. Any of these impacts could have a material adverse effect on our business, financial condition, and results of operations.
Governmental regulations affecting the import or export of products or affecting products containing encryption capabilities could negatively affect our revenues.
The United States and various foreign governments have imposed controls and restrictions on the import or export of, among other things, our products that contain or use encryption technology. Most of our products contain or use encryption technology and, consequently, are subject to such controls, requirements and restrictions. In addition, from time to time, governmental agencies have proposed additional regulation of
 
S-18

Table of Contents
encryption technology, such as requiring certification, notifications, review of source code, limiting the encryption features or the escrow and governmental recovery of private encryption keys. For example, China recently has proposed new requirements relating to products containing encryption and India has imposed special warranty and other obligations associated with technology deemed critical. Governmental regulation of encryption or IP networking technology and regulation of imports or exports, or our failure to obtain required import or export approval for our products, or export or related economic sanctions, including recent restrictions imposed by the U.S. and EU on exports to Russia and Ukraine, could harm our international and domestic sales and adversely affect our revenues. In addition, failure to comply with such regulations could result in harm to our reputation and ability to compete in international markets, penalties, costs, and restrictions on import or export privileges or adversely affect sales to government agencies or government-funded projects.
Our actual or perceived failure to adequately protect personal data could adversely affect our business, financial condition and results of operations.
A variety of state, national, foreign, and international laws and regulations apply to the collection, use, retention, protection, disclosure, transfer, and other processing of personal data. These privacy- and data protection-related laws and regulations are evolving, with new or modified laws and regulations proposed and implemented frequently and existing laws and regulations subject to new or different interpretations. Compliance with these laws and regulations can be costly and can delay or impede the development and offering of new products and services.
For example, we historically have relied upon adherence to the U.S. Department of Commerce’s Safe Harbor Privacy Principles and compliance with the U.S.-EU Safe Harbor Framework agreed to by the U.S. Department of Commerce and the EU. The U.S.-EU Safe Harbor Framework, which established means for legitimizing the transfer of personal data by U.S. companies from the European Economic Area, or EEA, to the U.S., recently was invalidated by a decision of the European Court of Justice, or the ECJ. In light of the ECJ’s decision, we are reviewing our business practices and may find it necessary or desirable to make changes to our personal data handling procedures and contractual arrangements to ensure our transfer and receipt of EEA residents’ personal data remains legitimized under applicable European law. Our actual or alleged failure to comply with applicable laws and regulations, or to protect personal data, could result in enforcement actions, significant penalties or other legal action against us or our customers or suppliers, which could result in negative publicity, increase our operating costs, subject us to claims or other remedies and have a material adverse effect on our business, financial condition, and results of operations.
Our ability to develop, market, and sell products could be harmed if we are unable to retain or hire key personnel.
Our future success depends upon our ability to recruit and retain the services of executive, engineering, sales and marketing, and support personnel. The supply of highly qualified individuals, in particular engineers in very specialized technical areas, or sales people specializing in the service provider and enterprise markets, is limited and competition for such individuals is intense. None of our officers or key employees is bound by an employment agreement for any specific term. The loss of the services of any of our key employees, the inability to attract or retain personnel in the future or delays in hiring required personnel, engineers and sales people, and the complexity and time involved in replacing or training new employees, could delay the development and introduction of new products, and negatively impact our ability to market, sell, or support our products.
Our financial condition and results of operations could suffer if there is an additional impairment of goodwill or other intangible assets with indefinite lives.
We are required to test intangible assets with indefinite lives, including goodwill, annually or more frequently if certain circumstances change that would more likely than not reduce the fair value of a reporting unit and intangible assets below their carrying values. As of December 31, 2015, our goodwill was $2,981.3
 
S-19

Table of Contents
million and there were no intangible assets with indefinite lives. When the carrying value of a reporting unit’s goodwill exceeds its implied fair value of goodwill, a charge to operations is recorded. If the carrying amount of an intangible asset with an indefinite life exceeds its fair value, a charge to operations is recorded. Either event would result in incremental expenses for that quarter, which would reduce any earnings or increase any loss for the period in which the impairment was determined to have occurred.
In the past, we recorded a goodwill impairment charge of $850.0 million due to the underperformance of our Security reporting unit and product rationalizations.
In recent years, economic weakness has contributed to extreme price and volume fluctuations in global stock markets that have reduced the market price of many technology company stocks, including ours. Declines in our level of revenues due to restructuring or cost reductions or declines in our operating margins, as well as sustained declines in our stock price, increase the risk that goodwill and intangible assets with indefinite lives may become impaired in future periods.
Our goodwill impairment analysis is sensitive to changes in key assumptions used in our analysis, such as expected future cash flows, the degree of volatility in equity and debt markets, and our stock price. If the assumptions used in our analysis are not realized, it is possible that an impairment charge may need to be recorded in the future. We cannot accurately predict the amount and timing of any impairment of goodwill or other intangible assets. However, any such impairment would have an adverse effect on our results of operations.
Changes in effective tax rates or adverse outcomes resulting from examination of our income or other tax returns could adversely affect our results.
Our future effective tax rates could be subject to volatility or adversely affected by the following: earnings being lower than anticipated in countries where we have lower statutory rates and higher than anticipated earnings in countries where we have higher statutory rates; changes in the valuation of our deferred tax assets and liabilities; expiration of, or lapses in, the R&D tax credit laws applicable to us; transfer pricing adjustments related to certain acquisitions, including the license of acquired intangibles under our intercompany R&D cost sharing arrangement; costs related to intercompany restructuring; tax effects of share-based compensation; challenges to our methodologies for valuing developed technology or intercompany arrangements; or changes in tax laws, regulations, accounting principles, or interpretations thereof. On October 5, 2015, the Organisation for Economic Co-operation and Development, or OECD, an international association of 34 countries including the U.S., published final proposals under its Base Erosion and Profit Shifting, or BEPS, Action Plan. The BEPS Action Plan includes fifteen Actions to address BEPS in a comprehensive manner and represents a significant change to the international corporate tax landscape. These proposals, if adopted by countries, may increase tax uncertainty and adversely affect our provision for income taxes. In addition, we are subject to the continuous examination of our income tax returns by the Internal Revenue Service, or IRS, and other tax authorities. It is possible that tax authorities may disagree with certain positions we have taken and any adverse outcome of such a review or audit could have a negative effect on our financial position and operating results. We regularly assess the likelihood of adverse outcomes resulting from these examinations to determine the adequacy of our provision for income taxes, but the determination of our worldwide provision for income taxes and other tax liabilities requires significant judgment by management, and there are transactions where the ultimate tax determination is uncertain. Although we believe that our estimates are reasonable, the ultimate tax outcome may differ from the amounts recorded in our consolidated financial statements and may materially affect our financial results in the period or periods for which such determination is made. There can be no assurance that the outcomes from continuous examinations will not have an adverse effect on our business, financial condition, and results of operations.

If we fail to accurately predict our manufacturing requirements, we could incur additional costs or experience manufacturing delays, which would harm our business.
We provide demand forecasts to our contract manufacturers, who order components and plan capacity based on these forecasts. If we overestimate our requirements, our contract manufacturers may assess charges, or we may have liabilities for excess inventory, each of which could negatively affect our gross margins. For example, in certain prior quarters, our gross margins were reduced as a result of an inventory charge resulting from inventory we held in excess of forecasted demand. Conversely, because lead times for required materials and components vary significantly and depend on factors such as the specific supplier, contract terms, and the demand for each component at a given time, and because our contract manufacturers are third-party manufacturers for numerous other companies, if we underestimate our requirements, as we have in certain prior quarters with respect to certain components, our contract manufacturers may have inadequate time, materials, and/or components required to produce our products, which could increase costs or delay or interrupt manufacturing of our products resulting in delays in shipments and deferral or loss of revenues and negatively impacting customer satisfaction.
We are dependent on contract manufacturers with whom we do not have long-term supply contracts, and changes to those relationships, expected or unexpected, may result in delays or disruptions that could cause us to lose revenues and damage our customer relationships.
We depend on independent contract manufacturers (each of which is a third-party manufacturer for numerous companies) to manufacture our products. Although we have contracts with our contract manufacturers, these contracts do not require them to manufacture our products on a long-term basis in any specific quantity or at any specific price. In addition, it is time-consuming and costly to qualify and implement additional contract manufacturer relationships. Therefore, if we fail to effectively manage our contract manufacturer relationships, which includes failing to provide accurate forecasts of our requirements, or if one or more of them experiences delays, disruptions, or quality control problems in our manufacturing operations, or if we had to change or add additional contract manufacturers or contract manufacturing sites, our ability to ship products to our customers could be delayed. Also, the addition of manufacturing locations or contract manufacturers would increase the complexity of our supply chain management. Moreover, an increasing portion of our manufacturing is performed in China and other countries and is therefore subject to risks associated with doing business outside of the United States. Each of these factors could adversely affect our business, financial condition and results of operations.
We may face difficulties enforcing our proprietary rights which could adversely affect our ability to compete.
We generally rely on a combination of patents, copyrights, trademarks, and trade secret laws and contractual restrictions on disclosure of confidential and proprietary information, to establish and maintain proprietary rights in our technology and products. Although we have been issued numerous patents and other patent applications are currently pending, there can be no assurance that any of our patent applications will result in issued patents or that any of our patents or other proprietary rights will not be challenged, invalidated, infringed or circumvented or that our rights will, in fact, provide competitive advantages to us or protect our technology, any of which could result in costly product redesign efforts, discontinuance of certain product offerings and other competitive harm.
In addition, despite our efforts to protect our proprietary rights, unauthorized parties may attempt to copy aspects of our products or obtain and use information that we regard as proprietary. We generally enter into confidentiality or license agreements with our employees, consultants, vendors, and customers, and generally limit access to and distribution of our proprietary information. However, we cannot assure you that we have entered into such agreements with all parties who may have or have had access to our confidential information or that the agreements we have entered into will not be breached. We cannot guarantee that any of the measures we have taken will prevent misappropriation of our technology.
Furthermore, the laws of some foreign countries may not protect our proprietary rights to the same extent as do the laws of the United States. The outcome of any actions taken in these foreign countries may be different
 
S-21

Table of Contents
than if such actions were determined under the laws of the United States. Although we are not dependent on any individual patents or group of patents for particular segments of the business for which we compete, if we are unable to protect our proprietary rights in a market, we may find ourselves at a competitive disadvantage to others who need not incur the substantial expense, time, and effort required to create innovative products that have enabled our success.
We are subject to risks arising from our international operations, which may adversely affect our business, financial condition, and results of operations.
We derive a substantial portion of our revenues from our international operations, and we plan to continue expanding our business in international markets in the future. We conduct significant sales and customer support operations directly and indirectly through our distributors and VARs in countries throughout the world and depend on the operations of our contract manufacturers and suppliers that are located outside of the United States. In addition, a portion of our R&D and our general and administrative operations are conducted outside the United States. In some countries, we may experience reduced intellectual property protection.
As a result of our international operations, we are affected by economic, business regulatory, social, and political conditions in foreign countries, including the following:
 
 	•	 	changes in general IT spending,	
 
 	•	 	the imposition of government controls, inclusive of critical infrastructure protection;	
 
 	•	 	changes or limitations in trade protection laws or other regulatory requirements, which may affect our ability to import or export our products from various countries;	
 
 	•	 	varying and potentially conflicting laws and regulations;	
 
 	•	 	fluctuations in local economies;	
 
 	•	 	wage inflation or a tightening of the labor market; and	
 
 	•	 	the impact of the following on service provider and government spending patterns: political considerations, unfavorable changes in tax treaties or laws, natural disasters, epidemic disease, labor unrest, earnings expatriation restrictions, misappropriation of intellectual property, military actions, acts of terrorism, political and social unrest and difficulties in staffing and managing international operations.	
Any or all of these factors could have a material adverse impact on our business, financial condition, and results of operations.
Moreover, local laws and customs in many countries differ significantly from or conflict with those in the United States or in other countries in which we operate. In many foreign countries, particularly in those with developing economies, it is common for others to engage in business practices that are prohibited by our internal policies and procedures or U.S. regulations applicable to us. There can be no assurance that our employees, contractors, channel partners, and agents will not take actions in violation of our policies and procedures, which are designed to ensure compliance with U.S. and foreign laws and policies. Violations of laws or key control policies by our employees, contractors, channel partners, or agents could result in termination of our relationship, financial reporting problems, fines, and/or penalties for us, or prohibition on the importation or exportation of our products, and could have a material adverse effect on our business, financial condition and results of operations.
We are exposed to fluctuations in currency exchange rates, which could negatively affect our financial condition and results of operations.
Because a substantial portion of our business is conducted outside the United States, we face exposure to adverse movements in non-U.S. currency exchange rates. These exposures may change over time as business practices evolve and could have a material adverse impact on our financial condition and results of operations.
 
S-22

Table of Contents
The majority of our revenues and expenses are transacted in U.S. Dollars. We also have some transactions that are denominated in foreign currencies, primarily the British Pound, Euro, Indian Rupee, and Japanese Yen related to our sales and service operations outside of the United States. An increase in the value of the U.S. Dollar could increase the real cost to our customers of our products in those markets outside the United States in which we sell in U.S. Dollars. This could negatively affect our ability to meet our customers’ pricing expectations in those markets and may result in erosion of gross margin and market share. A weakened U.S. Dollar could increase the cost of local operating expenses and procurement of raw materials to the extent we must purchase components in foreign currencies.
Currently, we hedge only those currency exposures associated with certain assets and liabilities denominated in nonfunctional currencies and periodically hedge anticipated foreign currency cash flows. The hedging activities undertaken by us are intended to offset the impact of currency fluctuations on certain nonfunctional currency assets and liabilities. However, such attempts to offset the impact of currency fluctuations are costly and no amount of hedging can be effective against all circumstances, including long-term declines in the value of the U.S. Dollar. If our attempts to hedge against these risks are not successful, or if long-term declines in the value of the U.S. Dollar persist, our financial condition and results of operations could be adversely impacted.
Integration of acquisitions could disrupt our business and harm our financial condition and stock price and may dilute the ownership of our stockholders.
We have made, and may continue to make, acquisitions in order to enhance our business. For example, in January 2016, we entered into a definitive agreement to acquire BTI Systems Inc.; in 2014, we acquired WANDL, Inc.; and in 2012, we acquired Contrail Systems Inc. and Mykonos Software, Inc. Acquisitions involve numerous risks, including problems combining the purchased operations, technologies or products, unanticipated costs and liabilities, diversion of management’s attention from our core businesses, adverse effects on existing business relationships with suppliers and customers, risks associated with entering markets in which we have no or limited prior experience, and potential loss of key employees. There can be no assurance that we will be able to integrate successfully any businesses, products, technologies, or personnel that we might acquire. The integration of businesses that we may acquire is likely to be a complex, time-consuming, and expensive process and we may not realize the anticipated revenues or other benefits associated with our acquisitions if we fail to successfully manage and operate the acquired business. If we fail in any acquisition integration efforts and are unable to efficiently operate as a combined organization utilizing common information and communication systems, operating procedures, financial controls, and human resources practices, our business, financial condition, and results of operations may be adversely affected.
In connection with certain acquisitions, we may agree to issue common stock or assume equity awards that dilute the ownership of our current stockholders, use a substantial portion of our cash resources, assume liabilities, record goodwill and amortizable intangible assets that will be subject to impairment testing on a regular basis and potential periodic impairment charges, incur amortization expenses related to certain intangible assets, and incur large and immediate write-offs and restructuring and other related expenses, all of which could harm our financial condition and results of operations.
Approximately $125 million of the transaction consideration we received from the divestiture of our Junos Pulse product portfolio is in the form of a non-contingent seller promissory note and we may not receive the amount owed to us (including accrued interest), including in the time frame contemplated, by the buyer under the note.
In the fourth quarter of fiscal 2014, we completed the sale of our Junos Pulse product portfolio to an affiliate of Siris Capital, a private equity firm, for total consideration of $230.7 million, of which $105.7 million was in cash, net of a $19.3 million working capital adjustment, and $125.0 million was in the form of an 18-month non-contingent interest-bearing promissory note issued to the Company. On October 2, 2015, the Company and
 
S-23

Table of Contents
the issuer of the promissory note agreed to modify the original terms of the note to extend the maturity date from April 1, 2016 to December 31, 2018. Since approximately $125.0 million of the transaction consideration is in the form of a non-contingent seller promissory note, there is the risk that we may not receive the amount owed to us (including accrued interest), including in the time frame contemplated, by the buyer under the note. In the event that the promissory note is not repaid on the terms we contemplate, any collection or restructuring efforts we undertake may be costly and require significant time and attention from our management.
If we fail to adequately evolve our financial and managerial control and reporting systems and processes, our ability to manage and grow our business will be negatively affected.
Our ability to successfully offer our products and implement our business plan in a rapidly evolving market depends upon an effective planning and management process. We will need to continue to improve our financial and managerial control and our reporting systems and procedures in order to manage our business effectively in the future. If we fail to effectively implement improved systems and processes, our ability to manage our business, financial condition, and results of operations may be negatively affected.
Our products are highly technical and if they contain undetected defects, errors or malware or do not meet customer quality expectations, our business could be adversely affected, and we may be subject to additional costs or lawsuits or be required to pay damages in connection with any alleged or actual failure of our products and services.
Our products are highly technical and complex, are critical to the operation of many networks, and, in the case of our security products, provide and monitor network security and may protect valuable information. Our products have contained and may contain one or more undetected errors, defects, malware, or security vulnerabilities. Some errors in our products may only be discovered after a product has been installed and used by end-customers. For example, in December 2015, we disclosed that we identified unauthorized code in ScreenOS that could allow a knowledgeable attacker to gain administrative access to NetScreen devices and to decrypt VPN connections.
Any errors, defects, malware or security vulnerabilities discovered in our products after commercial release could result in monetary penalties, loss of revenues or delay in revenue recognition, loss of customers, loss of future business and reputation, penalties, and increased service and warranty cost, any of which could adversely affect our business, financial condition, and results of operations. Following the identification of the ScreenOS vulnerabilities, we launched an investigation into the matter, developed patched releases for the latest versions of ScreenOS and notified customers, all of which required significant time and attention from management and our employees. In addition, in the event an error, defect, malware, or vulnerability is attributable to a component supplied by a third-party vendor, we may not be able to recover from the vendor all of the costs of remediation that we may incur. In addition, we could face claims for product liability, tort, or breach of warranty or indemnification. Defending a lawsuit, regardless of its merit, is costly and may divert management’s attention. If our business liability insurance coverage is inadequate, or future coverage is unavailable on acceptable terms or at all, our financial condition and results of operations could be harmed. Moreover, if our products fail to satisfy our customers’ quality expectations for whatever reason, the perception of and the demand for our products could be adversely affected.
If our products do not interoperate with our customers’ networks, installations will be delayed or cancelled and could harm our business.
Our products are designed to interface with our customers’ existing networks, each of which have different specifications and utilize multiple protocol standards and products from other vendors. Many of our customers’ networks contain multiple generations of products that have been added over time as these networks have grown and evolved. Our products must interoperate with many or all of the products within these networks as well as future products in order to meet our customers’ requirements. If we find errors in the existing software or defects
 
S-24

Table of Contents
in the hardware used in our customers’ networks, we may need to modify our software or hardware to fix or overcome these errors so that our products will interoperate and scale with the existing software and hardware, which could be costly and could negatively affect our business, financial condition, and results of operations. In addition, if our products do not interoperate with those of our customers’ networks, demand for our products could be adversely affected or orders for our products could be cancelled. This could hurt our operating results, damage our reputation, and seriously harm our business and prospects.
Our products incorporate and rely upon licensed third-party technology, and if licenses of third-party technology do not continue to be available to us or are not available on terms acceptable to us, our revenues and ability to develop and introduce new products could be adversely affected.
We integrate licensed third-party technology into certain of our products. From time to time, we may be required to license additional technology from third-parties to develop new products or product enhancements. Third-party licenses may not be available or continue to be available to us on commercially reasonable terms. The failure to comply with the terms of any license, including free open source software, may result in our inability to continue to use such license. Some of our agreements with our licensors may be terminated for convenience by them. In addition, we cannot be certain that our licensors are not infringing the intellectual property rights of third parties or that our licensors have sufficient rights to the licensed intellectual property in all jurisdictions in which we may sell our products. Our inability to maintain or re-license any third-party licenses required in our products or our inability to obtain third-party licenses necessary to develop new products and product enhancements, could require us, if possible, to develop substitute technology or obtain substitute technology of lower quality or performance standards or at a greater cost, any of which could delay or prevent product shipment and harm our business, financial condition, and results of operations.
We sell our products to customers that use those products to build networks and IP infrastructure, and if the demand for network and IP systems does not continue to grow, our business, financial condition, and results of operations could be adversely affected.
A substantial portion of our business and revenues depends on the growth of secure IP infrastructure and on the deployment of our products by customers that depend on the continued growth of IP services. As a result of changes in the economy, capital spending or the building of network capacity in excess of demand, all of which have in the past particularly affected telecommunications service providers, spending on IP infrastructure can vary, which could have a material adverse effect on our business, financial condition, and results of operations. In addition, a number of our existing customers are evaluating the build-out of their next generation networks. During the decision-making period when our customers are determining the design of those networks and the selection of the equipment they will use in those networks, such customers may greatly reduce or suspend their spending on secure IP infrastructure. Such delays in purchases can make it more difficult to predict revenues from such customers can cause fluctuations in the level of spending by these customers and, even where our products are ultimately selected, can have a material adverse effect on our business, financial condition, and results of operations.
We are required to evaluate the effectiveness of our internal control over financial reporting and publicly disclose material weaknesses in our controls. Any adverse results from such evaluation may adversely affect investor perception, our stock price and cause us to incur additional expense.
Section 404 of the Sarbanes-Oxley Act of 2002 requires our management to assess the effectiveness of our internal control over financial reporting and to disclose in our filing if such controls were unable to provide assurance that a material error would be prevented. We have an ongoing program to implement and test the system and process controls necessary to comply with these requirements. We have and will continue to incur significant expenses and devote management resources to Section 404 compliance. In the event that our Chief Executive Officer, Chief Financial Officer, or independent registered public accounting firm determine in the future that our internal controls over financial reporting are not effective as defined under Section 404, investor

perceptions regarding the reliability of our financial statements may be adversely affected which could cause a decline in the market price of our stock and otherwise negatively affect our liquidity and financial condition.
Failure to maintain our credit ratings could adversely affect our cost of funds and related margins, liquidity, competitive position and access to capital markets.
The major credit rating agencies routinely evaluate our indebtedness. This evaluation is based on a number of factors, which include financial strength as well as transparency with rating agencies and timeliness of financial reporting. There can be no assurance that we will be able to maintain our credit ratings and failure to do so could adversely affect our cost of funds and related margins, liquidity, competitive position and access to capital markets.
We may be unable to generate the cash flow to satisfy our expenses, make anticipated capital expenditures or service our debt obligations, including the Senior Notes and the Revolving Credit Facility.
In March 2015, we issued $300.0 million aggregate principal amount of 3.30% senior notes due 2020 (the “2020 Notes”), and $300.0 million aggregate principal amount of 4.35% senior notes due 2025 (the “2025 Notes”). In addition, in March 2014, we issued $350.0 million aggregate principal amount of 4.50% senior unsecured notes due 2024 (the “2024 Notes”) and in March 2011, we issued $1.0 billion aggregate principal amount of senior unsecured notes (the “Senior Notes” and together with the 2020 Notes, 2024 Notes and 2025 Notes, the “existing notes”) (see discussion in Note 10, Debt and Financing, in the Notes to Consolidated Financial Statements of our Annual Report on Form 10-K for the year ended December 31, 2015). As of December 31, 2015, we had $1,948.7 million in outstanding short-term and long-term debt. In June 2014, we entered into a Credit Agreement with certain institutional lenders that provides for a five year $500.0 million unsecured revolving credit facility, which we refer to as the Revolving Credit Facility, with an option to increase the Revolving Credit Facility, up to a maximum of $700.0 million. The Credit Agreement will terminate in June 2019, at which point all amounts borrowed must be repaid. As of December 31, 2015, no amounts were outstanding under the Credit Agreement.
We may not be able to generate sufficient cash flow to enable us to satisfy our expenses, make anticipated capital expenditures or service our indebtedness, including the existing notes and the Revolving Credit Facility (if drawn upon). Our ability to pay our expenses, satisfy our debt obligations, refinance our debt obligations and fund planned capital expenditures will depend on our future performance, which will be affected by general economic, financial, competitive, legislative, regulatory and other factors beyond our control. Based upon current levels of operations, we believe cash flow from operations and available cash will be adequate for at least the next twelve months to meet our anticipated requirements for working capital, capital expenditures and scheduled payments of principal and interest on our indebtedness, including the existing notes and the Revolving Credit Facility (if drawn upon). However, if we are unable to generate sufficient cash flow from operations or to borrow sufficient funds in the future to service our debt, we may be required to sell assets, reduce capital expenditures, refinance all or a portion of our existing debt (including the existing notes), repatriate off-shore cash to the U.S. at unfavorable tax rates or obtain additional financing. There is no assurance that we will be able to refinance our debt, sell assets or borrow more money on terms acceptable to us, or at all.
The indentures that govern the existing notes and the notes being offered hereby contain various covenants that limit our ability and the ability of our subsidiaries to, among other things:
 
 	•	 	incur liens;	
 
 	•	 	incur sale and leaseback transactions; and	
 
 	•	 	consolidate or merge with or into, or sell substantially all of our assets to, another person.	
 
S-26

Table of Contents
The Credit Agreement contains two financial covenants along with customary affirmative and negative covenants that include the following:
 
 	•	 	maintenance of a leverage ratio no greater than 3.0x and an interest coverage ratio no less than 3.0x	
 
 	•	 	covenants that limit or restrict the ability of the Company and its subsidiaries to, among other things, grant liens, merge or consolidate, dispose of all or substantially all of its assets, change their accounting or reporting policies, change their business and incur subsidiary indebtedness, in each case subject to customary exceptions for a credit facility of this size and type.	
As a result of these covenants, we are limited in the manner in which we can conduct our business, and we may be unable to engage in favorable business activities or finance future operations or capital needs. Accordingly, these restrictions may limit our ability to successfully operate our business. A failure to comply with these restrictions could lead to an event of default, which could result in an acceleration of the indebtedness. Our future operating results may not be sufficient to enable compliance with these covenants to remedy any such default. In addition, in the event of an acceleration, we may not have or be able to obtain sufficient funds to make any accelerated payments, including those under the existing notes, any notes issued in connection with the recently-announced capital return program discussed below and the Revolving Credit Facility (if drawn upon).
Our failure to pay quarterly dividends to our stockholders or the failure to meet our commitments to return capital to our stockholders could have a material adverse effect on our stock price.
In January 2016, we announced a cash dividend of $0.10 per share of common stock payable on March 22, 2016 to stockholders of record as of the close of business on March 1, 2016. Our ability to pay quarterly dividends will be subject to, among other things, our financial position and results of operations, available cash and cash flow, capital requirements and other factors. Any failure to pay or increase future dividends as announced, reduction or discontinuation of quarterly dividends could have a material adverse effect on our stock price.
In addition, in October 2014 and July 2015, our Board of Directors authorized a $500.0 million and a $1.1 billion increase, respectively, to our current capital return plan. The capital return plan will be funded by a combination of onshore cash, previously issued debt and, potentially, additional debt financing, to preserve our financial flexibility to invest in future growth opportunities and maintain our investment grade credit rating. Any failure to meet our commitments to return capital to our stockholders could have a material adverse effect on our stock price.
The investment of our cash balance and our investments in government and corporate debt securities are subject to risks, which may cause losses and affect the liquidity of these investments.
At December 31, 2015, we had $1,420.9 million in cash and cash equivalents and $1,771.3 million in short-and long-term investments. We have invested these amounts primarily in asset-backed securities, certificates of deposit, commercial paper, corporate debt securities, foreign government debt securities, government- sponsored enterprise obligations, money market funds, mutual funds, publicly-traded equity securities, time deposits and U.S. government securities. Certain of these investments are subject to general credit, liquidity, market, sovereign debt, and interest rate risks. Our future investment income may fall short of expectations due to changes in interest rates or if the decline in fair value of our publicly traded debt or equity investments is judged to be other-than-temporary. These market risks associated with our investment portfolio may have a material adverse effect on our liquidity, financial condition, and results of operations.
Uninsured losses could harm our operating results.
We self-insure against many business risks and expenses, such as intellectual property litigation and our medical benefit programs, where we believe we can adequately self-insure against the anticipated exposure and risk or where insurance is either not deemed cost-effective or is not available. We also maintain a program of insurance coverage for various types of property, casualty, and other risks. We place our insurance coverage with
 
S-27

Table of Contents
various carriers in numerous jurisdictions. The types and amounts of insurance that we obtain vary from time to time and from location to location, depending on availability, cost, and our decisions with respect to risk retention. The policies are subject to deductibles, policy limits, and exclusions that result in our retention of a level of risk on a self-insurance basis. Losses not covered by insurance could be substantial and unpredictable and could adversely affect our financial condition and results of operations.
Risks Relating to the Notes
The notes are our obligations and not obligations of our subsidiaries and will be structurally subordinated to the claims of our subsidiaries’ creditors.
The notes are exclusively our obligations and not those of our subsidiaries. We conduct a substantial portion of our operations through our subsidiaries. As a result, our ability to make payments on the notes will depend upon the receipt of dividends and other distributions from our subsidiaries. If we do not receive sufficient cash dividends and other distributions from our subsidiaries, it is unlikely that we will have sufficient funds to make payments on the notes.
Our subsidiaries are separate and distinct legal entities. Our subsidiaries have no obligation to pay any amounts due on the notes or to provide us with funds to pay our obligations, whether by dividends, distributions, loans or other payments. In addition, any dividend payments, distributions, loans or advances to us by our subsidiaries in the future will require the generation of future earnings by our subsidiaries and may require regulatory approval. If our subsidiaries are unable to make dividend payments to us and sufficient capital is not otherwise available, we may not be able to make principal and interest payments on our debt, including the notes.
In addition, our right to participate in any distribution of assets of any of our subsidiaries upon the subsidiary’s liquidation or otherwise will generally be subject to the prior claims of creditors of that subsidiary. Your ability as a holder of the notes to benefit indirectly from that distribution also will be subject to these prior claims. The notes are not guaranteed by any of our subsidiaries. As a result, the notes will be structurally subordinated to all existing and future liabilities and obligations of our subsidiaries, which means that our subsidiaries’ creditors will be paid from our subsidiaries’ assets before holders of the notes would have any claims to those assets. At December 31, 2015, the aggregate amount of all debt and other liabilities of our consolidated subsidiaries that would structurally rank senior to the notes was approximately $1,524 million. We intend to use a portion of the proceeds of this offering to repay the $300 million aggregate principal amount of the 2016 Senior Notes that mature on March 15, 2016. Our subsidiaries may incur additional debt and liabilities in the future, all of which would rank structurally senior to the notes.
The notes will be effectively junior to all of our secured indebtedness.
The notes will be effectively subordinated to any future secured debt we may incur to the extent of the value of the assets securing such debt. In the event that we are declared bankrupt, become insolvent or are liquidated or reorganized, any debt that ranks ahead of the notes will be entitled to be paid in full from our assets before any payment may be made 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 ranking 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 may not have sufficient assets to pay amounts due on the notes. As a result, if holders of the notes receive any payments, they may receive less, ratably, than holders of secured indebtedness.
Although we do not currently have outstanding any secured indebtedness for money borrowed, the indenture under which the notes will be issued does not preclude us from issuing secured debt. See the section of this prospectus supplement entitled “Description of the Notes—Certain Covenants.”
 
S-28

Table of Contents
The limited covenants in the indenture for the notes and the terms of the notes do not provide protection against some types of important corporate events and may not protect your investment.
The indenture for the notes does not:
 
 	•	 	require us to maintain any financial ratios or specific levels of net worth, revenues, income, cash flow or liquidity and, accordingly, does not protect holders of the notes in the event that we experience significant adverse changes in our financial condition or results of operations;	
 
 	•	 	limit our subsidiaries’ ability to incur indebtedness, which could structurally rank senior to the notes;	
 
 	•	 	limit our ability to incur substantial secured indebtedness that would effectively rank senior to the notes to the extent of the value of the assets securing the indebtedness;	
 
 	•	 	limit our ability to incur indebtedness that is equal in right of payment to the notes;	
 
 	•	 	restrict our subsidiaries’ ability to issue securities or otherwise incur indebtedness that would be senior to our equity interests in our subsidiaries;	
 
 	•	 	restrict our ability to repurchase or prepay our securities; or	
 
 	•	 	restrict our ability to make investments or to repurchase or pay dividends or make other payments in respect of our common stock or other securities ranking junior to the notes.	
Furthermore, the indenture for the notes does not contain protections in the event of a change in control, unless accompanied by certain ratings downgrades. We could engage in many types of transactions, such as certain acquisitions, refinancings or recapitalizations that could substantially affect our capital structure and the value of the notes. For these reasons, you should not consider the covenants in the indenture as a significant factor in evaluating whether to invest in the notes.
We may be unable to generate the cash flow to service our debt obligations, including the notes.
As of December 31, 2015, we had $1,648.8 million in outstanding long-term debt and $299.9 million in outstanding short-term debt. As of December 31, 2015, we had $1,948.7 million of senior unsecured indebtedness outstanding, and we intend to use a portion of the proceeds of this offering to repay the $300 million aggregate principal amount of the 2016 Senior Notes that mature on March 15, 2016. We may not be able to generate sufficient cash flow to enable us to service our indebtedness, including the notes, or to make anticipated capital expenditures. Our ability to pay our expenses and satisfy our debt obligations, refinance our debt obligations and fund planned capital expenditures will depend on our future performance, which will be affected by general economic, financial, competitive, legislative, regulatory and other factors beyond our control. Based upon current levels of operations, we believe cash flow from operations and available cash will be adequate for the foreseeable future to meet our anticipated requirements for working capital, capital expenditures and scheduled payments of principal and interest on our indebtedness, including the notes. However, if we are unable to generate sufficient cash flow from operations or to borrow sufficient funds in the future to service our debt, we may be required to sell assets, reduce capital expenditures, refinance all or a portion of our existing debt (including the notes) or obtain additional financing. We cannot assure you that we will be able to refinance our debt, sell assets or borrow more money on terms acceptable to us, if at all.
We are permitted to incur more debt, which may intensify the risks associated with our current leverage, including the risk that we will be unable to service our debt.
The indenture governing the notes does not limit the amount of additional debt that we may incur. If we incur additional debt, however, the risks associated with our leverage, including the risk that we will be unable to service our debt, will increase.

Table of Contents
You may be unable to sell the notes because there are no public trading markets for the notes.
The notes are new issues of securities with no established trading markets. The notes will not be listed on any securities exchange or included in any automated quotation system. Consequently, the notes will be relatively illiquid and you may be unable to sell your notes. Although the representatives of the underwriters have advised us that, following completion of the offering of the notes, one or more of the underwriters currently intend to make a secondary market in the notes of each series, they are not obligated to do so and may discontinue any market-making activities at any time without notice. Accordingly, trading markets for the notes may not develop or any such markets may not have sufficient liquidity. Accordingly, we cannot assure you that trading markets for the notes will ever develop or be maintained. Many factors independent of our creditworthiness affect the trading market. These factors include the:
 
 	•	 	propensity of existing holders to trade their positions in the notes;	
 
 	•	 	time remaining to the maturity of the notes;	
 
 	•	 	outstanding amount of each series of notes;	
 
 	•	 	redemption of the notes; and	
 
 	•	 	level, direction and volatility of market interest rates generally.	
The prices at which you will be able to sell your notes prior to maturity will depend on a number of factors and may be substantially less than the amount you originally invest.
We believe that the value of each series of notes in any secondary market will be affected by the supply and demand for the notes, the interest rate and a number of other factors. Some of these factors are interrelated in complex ways. As a result, the effect of any one factor may be offset or magnified by the effect of another factor. The following paragraphs describe what we expect to be the impact on the market value of the notes of a change in a specific factor, assuming all other conditions remain constant.
U.S. interest rates . We expect that the market value of the notes will be affected by changes in U.S. interest rates. In general, if U.S. interest rates increase, the market value of the notes may decrease.
Our credit rating, financial condition and results . Actual or anticipated changes in our credit ratings or financial condition may affect the market value of each series of notes.
We want you to understand that the impact of one of the factors above, such as an increase in U.S. interest rates, may offset some or all of any change in the market value of the notes attributable to another factor, such as an improvement in our credit rating.
Ratings of the notes may change after issuance and affect the market price and marketability of the notes.
We currently expect that, prior to issuance, the notes will be rated by one or more ratings agencies. Such ratings are limited in scope, and do not address all material risks relating to an investment in the notes, but rather reflect only the view of each rating agency at the time the rating is issued. An explanation of the significance of such rating may be obtained from such rating agency. There is no assurance that such credit ratings will be issued or remain in effect for any given period of time or that such ratings will not be lowered, suspended or withdrawn entirely by the rating agencies, if, in each rating agency’s judgment, circumstances so warrant. It is also possible that such ratings may be lowered in connection with future events, such as future acquisitions or regulatory action taken against us. Any lowering, suspension or withdrawal of such ratings or the anticipation of such changes may have an adverse effect on the market prices or marketability of the notes. In addition, any decline in the ratings of the notes may make it more difficult for us to raise capital on acceptable terms.

The notes contain restrictive covenants that may adversely affect our ability to operate our business.
The indenture that will govern the notes and that governs our existing senior notes contains various covenants that limit our ability and the ability of our subsidiaries to, among other things:
 
 	•	 	incur liens;	
 
 	•	 	incur sale and leaseback transactions; and	
 
 	•	 	consolidate or merge with or into, or sell substantially all of our assets to, another person.	
As a result of these covenants, we are limited in the manner in which we can conduct our business, and we may be unable to engage in favorable business activities or finance future operations or capital needs. Accordingly, these restrictions may limit our ability to successfully operate our business. A failure to comply with these restrictions could lead to an event of default, which could result in an acceleration of the indebtedness. Our future operating results may not be sufficient to enable compliance with these covenants to remedy any such default. In addition, in the event of an acceleration, we may not have or be able to obtain sufficient funds to make any accelerated payments, including those under the notes and our existing senior notes. See “Description of the Notes—Certain Covenants.”
The negative covenants in the indenture that governs the notes may have a limited effect.
The indenture governing the notes contains covenants limiting our ability and our subsidiaries’ ability to create certain liens, enter into certain sale and leaseback transactions, and consolidate or merge with, or convey, transfer or lease all or substantially all of our assets to, another person. The limitation on liens and limitation on sale and leaseback transactions covenants contain exceptions that will allow us and our subsidiaries to incur liens with respect to material assets. See “Description of the Notes—Certain Covenants” in this prospectus supplement. In light of these exceptions and other factors described above, holders of the notes may be structurally or contractually subordinated to new lenders.
We may not be able to repurchase all of the notes upon a change of control repurchase event.
As described under “Description of the Notes—Purchase of Notes upon a Change of Control Repurchase Event,” we will be required to offer to repurchase the notes upon the occurrence of a change of control repurchase event. We may not have sufficient funds to repurchase the notes in cash at such time or have the ability to arrange necessary financing on acceptable terms. In addition, our ability to repurchase the notes for cash may be limited by law or the terms of other agreements relating to our indebtedness outstanding at the time.
The provisions in the indenture that governs the notes relating to change of control transactions will not necessarily protect you in the event of a highly leveraged transaction.
The provisions in the indenture will not necessarily afford you protection in the event of a highly leveraged transaction that may adversely affect you, including a reorganization, restructuring, merger or other similar transaction involving us. These transactions may not involve a change in voting power or beneficial ownership or, even if they do, may not involve a change of the magnitude required under the definition of change of control repurchase event in the indenture to trigger these provisions, notably, that the transactions are accompanied or followed within 60 days by a downgrade in the rating of the notes, following which the notes are no longer rated “investment grade.” Except as described under “Description of the Notes—Purchase of Notes upon a Change of Control Repurchase Event,” the indenture does not contain provisions that permit the holders of the notes to require us to repurchase the notes in the event of a takeover, recapitalization or similar transaction.
You may not be able to determine when a change of control repurchase event has occurred.
The definition of change of control, which is a condition precedent to a change of control repurchase event, includes a phrase relating to the sale, lease, transfer, conveyance or other disposition of “all or substantially all”
 
S-31

Table of Contents
of our assets. Although there is a limited body of case law interpreting the phrase “substantially all,” there is no precise established definition of the phrase under applicable law. Accordingly, your ability to require us to repurchase your notes as a result of a sale, lease, transfer, conveyance or other disposition of less than all of our assets and the assets of our subsidiaries taken as a whole to another person may be uncertain.
Redemption may adversely affect your return on the notes.
We have the right to redeem some or all of the notes of either series prior to maturity, as described under “Description of Notes—Optional Redemption” in this prospectus supplement. We may redeem the notes at times when prevailing interest rates may be relatively low. Accordingly, you may not be able to reinvest the amount received upon a redemption in a comparable security at effective interest rates as high as that of the notes.

 USE OF PROCEEDS
We expect to receive net proceeds from this offering of approximately $             after deducting underwriting discounts and estimated expenses payable by us. We will use the net proceeds from the sale of the notes offered by this prospectus supplement for general corporate purposes, which is expected to include repayment of $300 million aggregate principal amount of our outstanding 2016 Senior Notes at maturity, share repurchases and payment of dividends under our program to return capital to stockholders and funding for working capital, capital expenditures, other corporate expenses and acquisitions of products, technologies or businesses. From time to time, we evaluate potential acquisitions of products, technologies or businesses; however, we do not currently have any agreements with respect to any such material acquisitions. The timing and amount of our actual expenditures will be based on many factors, including cash flows from operations and the anticipated growth of our business. As a result, our management will have broad discretion to allocate the net proceeds of the offering. Net proceeds may be temporarily invested in interest-bearing instruments prior to use.
The $300 million aggregate principal amount of our outstanding 2016 Senior Notes to be repaid using the proceeds of the notes bear interest at 3.100% and have a maturity date of March 15, 2016.

 DESCRIPTION OF THE NOTES
We will issue the notes as separate series of debt securities as defined in the accompanying prospectus. The following description of the terms of the notes offered hereby supplements, and to the extent inconsistent therewith replaces, the description of the general terms and provisions of the debt securities under the heading “Description of the Debt Securities” in the accompanying prospectus. The notes are to be issued under an indenture, dated as of March 3, 2011, between us and The Bank of New York Mellon Trust Company, N.A., as trustee (the “base indenture”) and a supplemental indenture to be dated as of the date the notes are issued (together with the base indenture, the “indenture”). The following summary of the provisions of the indenture and the notes does not purport to be complete and is subject to, and qualified in its entirety by reference to, all of the provisions of the indenture, including definitions therein of certain terms and provisions made a part of the indenture by reference to the Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”). Wherever particular provisions or defined terms of the indenture or form of note are referred to, these provisions or defined terms are incorporated in this prospectus by reference. You may request a copy of the indenture from us as set forth in “Incorporation by Reference.” We urge you to read the indenture (including the form of note contained therein) because it, and not this description, defines your rights as a holder of the notes. For purposes of this description, references to the “Company,” “we,” “our” and “us” refer only to Juniper Networks, Inc. and not to its subsidiaries.
General
The notes will have the following basic terms:
 
 	•	 	the notes will be our senior unsecured obligations and will rank equally with all of our other unsecured and unsubordinated debt obligations, including our 3.100% Senior Notes due 2016 (the “2016 Senior Notes”), 3.300% Senior Notes due 2020, 4.600% Senior Notes due 2021, 4.500% Senior Notes due 2024, 4.350% Senior Notes due 2025 and 5.950% Senior Notes due 2041 (collectively, the “existing notes”) and our revolving credit facility. As of December 31, 2015, we had $1,948.7 million of senior unsecured indebtedness outstanding, and we intend to use a portion of the proceeds of this offering to repay the $300 million aggregate principal amount of the 2016 Senior Notes that mature on March 15, 2016;	
 
 	•	 	the notes will effectively rank junior to all liabilities of our subsidiaries. As of December 31, 2015, our subsidiaries had approximately $1,524 million of outstanding liabilities, including trade payables but excluding intercompany liabilities and liabilities of a type not required to be reflected on a balance sheet of such subsidiaries in accordance with generally accepted accounting principles (“GAAP”);	
 
 	•	 	the 20     notes initially will be limited to $             aggregate principal amount (subject to our rights to issue additional notes as described under “—Further Issuances” below);	
 
 	•	 	the 20     notes initially will be limited to $             aggregate principal amount (subject to our rights to issue additional notes as described under “—Further Issuances” below);	
 
 	•	 	the 20     notes will accrue interest at a rate of     % per year;	
 
 	•	 	the 20     notes will accrue interest at a rate of     % per year;	
 
 	•	 	the 20     notes will mature on                     , 20     unless redeemed or repurchased prior to that date;	
 
 	•	 	the 20     notes will mature on                     , 20     unless redeemed or repurchased prior to that date;	
 
 	•	 	interest will accrue on the notes from the most recent interest payment date to or for which interest has been paid or duly provided for (or if no interest has been paid or duly provided for, from the issue date of the notes), payable semi-annually in arrears on                     and                      of each year, beginning on                     , 2016;	
 
S-35

Table of Contents

 	•	 	interest on the notes will be paid to the person in whose name that note is registered at the close of business on                     or                     , as the case may be, immediately preceding the relevant interest payment date. Interest on the notes will be computed on the basis of a 360-day year comprised of twelve 30-day months;	
 
 	•	 	if any interest or other payment date of a note falls on a day that is not a business day, the required payment of principal, premium, if any, or interest will be due on the next succeeding business day as if made on the date that the payment was due, and no interest will accrue on that payment for the period from and after that interest or other payment date, as the case may be, to the date of that payment on the next succeeding business day. The term “business day” when used with respect to any note, means each Monday, Tuesday, Wednesday, Thursday and Friday which is not a day on which banking institutions in New York, New York (or such other place of payment as may be subsequently specified by us) are authorized or obligated by law or executive order to close;

References herein to “the notes” refer to our     % Senior Notes due 20     and our     % Senior Notes due 20     offered hereby.
Ranking
The notes will be our senior unsecured and unsubordinated obligations and will rank equally in right of payment with all of our unsecured and unsubordinated obligations, including the existing notes and our revolving credit facility. However, the notes are structurally subordinated to the indebtedness of our subsidiaries and will be effectively subordinated to any secured indebtedness to the extent of the value of the assets securing such indebtedness. Claims of the creditors of our subsidiaries will generally have priority with respect to the assets and earnings of such subsidiaries over the claims of our creditors, including holder of the notes. Accordingly, the notes will be effectively subordinated to creditors, including trade creditors and preferred stockholders, if any, of our subsidiaries.
As of December 31, 2015, we had $1,948.7 million of senior unsecured indebtedness outstanding, and we intend to use a portion of the proceeds of this offering to repay the $300 million aggregate principal amount of the 2016 Senior Notes that mature on March 15, 2016.
Further Issuances
We may from time to time, without notice to or the consent of the holders of the notes, create and issue additional notes of a series having the same terms as, and ranking equally and ratably with, the applicable series
 
S-36

Table of Contents
of notes in all respects (except for the issue date, the public offering price and, if applicable, the payment of interest accruing prior to the issue date of such additional notes and the first payment of interest following the issue date of such additional notes); provided that if such additional notes are not fungible with the notes of the applicable series offered hereby for U.S. federal income tax purposes, such additional notes will have a separate CUSIP number. Such additional notes may be consolidated and form a single series with, and will have the same terms as to ranking, redemption, waivers, amendments or otherwise, as the applicable series of notes, and will vote together as one class on all matters with respect to such series of notes.
Optional Redemption
We may redeem the 20     notes at our option, either in whole or in part, at any time and we may redeem the 20     notes at our option, either in whole or in part, at any time     months prior to the maturity date of the 20     notes, in each case at a redemption price equal to the greater of the following amounts, plus, in each case, accrued and unpaid interest thereon to, but not including, the redemption date:
 
 	•	 	100% of the aggregate principal amount of the notes to be redeemed; or	
 
 	•	 	the sum of the present values of the Remaining Scheduled Payments.	
In determining the present values of the Remaining Scheduled Payments, we will discount such payments to the redemption date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) using a discount rate equal to the Treasury Rate plus             basis points for the 20     notes and              basis points for the 20     notes.
At any time on or after                     ,                     , in the case of the 20     notes (     months prior to the maturity date of the 20     notes), we may redeem the 20     notes, in whole or in part, at a redemption price equal to 100% of the principal amount of the notes, plus accrued and unpaid interest to, but not including, the redemption date.
The following terms are relevant to the determination of the redemption price:
“ Comparable Treasury Issue ” means the U.S. Treasury security selected by an Independent Investment Banker as having an actual or interpolated maturity comparable to the remaining term of the applicable notes to be redeemed that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of such notes.
“ Comparable Treasury Price ” means, with respect to any redemption date, (1) the arithmetic average of the applicable Reference Treasury Dealer Quotations for such redemption date after excluding the highest and lowest Reference Treasury Dealer Quotations, or (2) if we obtain fewer than four applicable Reference Treasury Dealer Quotations, the arithmetic average of all applicable Reference Treasury Dealer Quotations for such redemption date.
“ Independent Investment Banker ” means Barclays Capital Inc., Citigroup Global Markets Inc. and J.P. Morgan Securities LLC, or their respective successors as we may appoint from time to time; provided, however, that if any of the foregoing ceases to be a primary U.S. Government securities dealer in the United States (a “primary treasury dealer”), we will substitute another primary treasury dealer.
“ Reference Treasury Dealer Quotations ” means, with respect to each Reference Treasury Dealer and any redemption date, the arithmetic average, as determined by us, of the bid and asked prices for the applicable Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to us by such Reference Treasury Dealer as of 5:00 p.m., New York City time, on the third business day preceding such redemption date.
 
S-37

Table of Contents
“ Reference Treasury Dealer ” means Barclays Capital Inc., Citigroup Global Markets Inc. and J.P. Morgan Securities LLC and two other primary treasury dealers selected by us, and each of their respective successors and any other primary treasury dealers selected by us.
“ Remaining Scheduled Payments ” means, with respect to any note to be redeemed, the remaining scheduled payments of the principal thereof and interest thereon that would be due after the related redemption date but for such redemption; provided, however, that, if such redemption date is not an interest payment date with respect to such note, the amount of the next scheduled interest payment thereon will be reduced by the amount of interest accrued thereon to such redemption date.
“ Treasury Rate ” means, with respect to any redemption date, the rate per annum equal to the semi-annual equivalent yield to maturity (computed as of the third business day immediately preceding that redemption date) of the applicable Comparable Treasury Issue. In determining this rate, we will assume a price for the applicable Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the applicable Comparable Treasury Price for such redemption date.
Notice of any redemption will be electronically delivered or mailed at least 30 days but not more than 60 days before the redemption date to each holder of the notes to be redeemed. In the event that we choose to redeem less than all of the notes, selection of the notes for redemption will be made in accordance with the procedures of the depositary. Unless we default in payment of the redemption price, on and after the redemption date interest will cease to accrue on the notes, or portions thereof, called for redemption.
Purchase of Notes upon a Change of Control Repurchase Event
If a change of control repurchase event occurs with respect to a series of notes, unless we have exercised our right to redeem such notes as described above under “—Optional Redemption,” we will be required to make an offer to each holder of the applicable notes to repurchase all or any part (in excess of $2,000 and in integral multiples of $1,000) of that holder’s notes of such series, at a repurchase price in cash equal to 101% of the aggregate principal amount of the notes repurchased plus any accrued and unpaid interest on the notes repurchased to, but not including, the date of repurchase.
Within 30 days following any change of control repurchase event or, at our option, prior to any change of control, but after the public announcement of the change of control, we will electronically deliver or mail a notice to each holder, with a copy to the trustee, describing the transaction or transactions that constitute or may constitute the change of control repurchase event and offering to repurchase the notes on the payment date specified in the notice, which date will be no earlier than 30 days and no later than 60 days from the date such notice is electronically delivered or mailed (the “Change of Control Payment Date”). The notice shall, if electronically delivered or mailed prior to the date of consummation of the change of control, state that the offer to purchase is conditioned on a change of control repurchase event occurring on or prior to the payment date specified in the notice. We will comply with the requirements of Rule 14e-1 under the Exchange Act, and any other securities laws and regulations thereunder, to the extent those laws and regulations are applicable in connection with the repurchase of the notes as a result of a change of control repurchase event. To the extent that the provisions of any securities laws or regulations conflict with the change of control repurchase event provisions of the notes, we will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under the change of control repurchase event provisions of the notes by virtue of such conflict.
On the repurchase date following a change of control repurchase event, we will, to the extent lawful:
 
 	(1)	accept for payment all the notes or portions of the notes properly tendered pursuant to its offer;	
 
 	(2)	deposit with the paying agent an amount equal to the change of control payment in respect of all the notes or portions of the notes properly tendered; and	
 
S-38

Table of Contents

 	(3)	deliver or cause to be delivered to the trustee the notes properly accepted, together with an officers’ certificate stating the aggregate principal amount of notes being purchased.	
The paying agent will promptly deliver to each holder of notes properly tendered the payment for the notes, and the trustee will promptly authenticate and deliver (or cause to be transferred by book-entry) to each holder a new note equal in principal amount to any unpurchased portion of any notes surrendered.
We will not be required to make an offer to repurchase the notes upon a change of control repurchase event if a third party makes such an offer in the manner, at the times and otherwise in compliance with the requirements for an offer made by us and such third party purchases all notes properly tendered and not withdrawn under its offer.
If holders of not less than 95% in aggregate principal amount of the applicable outstanding series of notes validly tender and do not withdraw such notes in an offer to repurchase the notes upon a change of control repurchase event and we, or any third party making an offer to repurchase the notes upon a change of control repurchase event in lieu of us, as described above, purchases all of the notes validly tendered and not withdrawn by such holders, we will have the right, upon not less than 30 nor more than 60 days’ prior notice, given not more than 30 days following the Change of Control Payment Date, to redeem all notes that remain outstanding following such purchase at a redemption price in cash equal to 101% of the principal amount thereof, plus accrued and unpaid interest, if any, to the date of redemption.
The change of control repurchase event feature of the notes may in certain circumstances make more difficult or discourage a sale or takeover of us and, thus, the removal of incumbent management. The change of control repurchase event feature is a result of negotiations between us and the underwriters. We have no present intention to engage in a transaction involving a change of control, although it is possible that we could decide to do so in the future. Subject to the limitations discussed below, we could, in the future, enter into certain transactions, including acquisitions, refinancings or other recapitalizations, that would not constitute a change of control under the indenture, but that could increase the amount of indebtedness outstanding at such time or otherwise affect our capital structure or the credit ratings of the notes. Restrictions on our ability to incur liens and enter into sale and leaseback transactions are contained in the covenants as described under “—Certain Covenants—Limitation on Liens” and “—Certain Covenants—Limitation on Sale and Leaseback Transactions.” Except for the limitations contained in such covenants and the covenant relating to repurchases upon the occurrence of a change of control repurchase event, however, the indenture will not contain any covenants or provisions that may afford holders of the notes protection in the event of a highly leveraged transaction.
The phrase “all or substantially all,” as used with respect to our assets and subsidiaries in the definition of “change of control,” is subject to interpretation under applicable state law, and its applicability in a given instance would depend upon the facts and circumstances. As a result, there may be a degree of uncertainty in ascertaining whether a sale or transfer of “all or substantially all” of our assets and the assets of our subsidiaries has occurred in a particular instance, in which case a holder’s ability to obtain the benefit of these provisions could be unclear. In addition, it should be noted that recent case law suggests that, in the event that incumbent directors are replaced as a result of a contested election, issuers may nevertheless avoid triggering a change of control under a clause similar to clause (4) of the definition of “change of control,” if the outgoing directors were to approve the new directors (without endorsing them or while simultaneously recommending and endorsing its own slate) for the purpose of such change of control clause as long as the approval was made in good faith, in accordance with the board of directors’ fiduciary duties.
We may not have sufficient funds to repurchase all the notes upon a change of control repurchase event. In addition, even if we have sufficient funds, we may be prohibited from repurchasing the notes under the terms of our future debt instruments. See “Risk Factors—Risks Related to the Notes—We may not be able to repurchase all of the notes upon a change of control repurchase event.”

Table of Contents
For purposes of the foregoing discussion of a repurchase at the option of holders, the following definitions are applicable:
“ change of control ” means the occurrence of any of the following: (1) the direct or indirect sale, transfer, conveyance or other disposition (other than by way of merger or consolidation), in one or a series of related transactions, of all or substantially all of our assets and the assets of our subsidiaries taken as a whole to any “person” (as that term is used in Section 13(d)(3) of the Exchange Act) other than to us or one of our subsidiaries; (2) the adoption of a plan relating to our liquidation or dissolution; (3) the consummation of any transaction (including, without limitation, any merger or consolidation) the result of which is that any “person” (as defined above), including any group defined as a person for the purpose of Section 13(d)(3) of the Exchange Act, becomes the beneficial owner, directly or indirectly, of more than 50% of the then outstanding number of shares of our voting stock; provided, however, that a person shall not be deemed beneficial owner of, or to own beneficially, (A) any securities tendered pursuant to a tender or exchange offer made by or on behalf of such person or any of such person’s affiliates until such tendered securities are accepted for purchase or exchange thereunder, or (B) any securities if such beneficial ownership (i) arises solely as a result of a revocable proxy delivered in response to a proxy or consent solicitation made pursuant to the applicable rules and regulations under the Exchange Act, and (ii) is not also then reportable on Schedule 13D (or any successor schedule) under the Exchange Act; (4) the first day on which a majority of the members of our board of directors cease to be continuing directors; or (5) we consolidate with, or merge with or into, any person, or any person consolidates with, or merges with or into, us, in any such event pursuant to a transaction in which any of our outstanding voting stock or the outstanding voting stock of such other person is converted into or exchanged for cash, securities or other property, other than any such transaction where the shares of our voting stock outstanding immediately prior to such transaction constitute, or are converted into or exchanged for, a majority of the voting stock of the surviving person or parent entity thereof immediately after giving effect to such transaction. Notwithstanding the foregoing, a transaction will not be considered to be a Change of Control if (a) we become a direct or indirect wholly-owned subsidiary of another person and (b) immediately following that transaction, a majority of voting stock of such person is held by the direct or indirect holders of our voting stock immediately prior to such transaction and in substantially the same proportion as immediately prior to such transaction.
“ change of control repurchase event ” means the occurrence of both a change of control and a ratings event.
“ continuing directors ” means, as of any date of determination, any member of our board of directors who (1) was a member of our board of directors on the date of the issuance of the notes; or (2) was nominated for election, elected or appointed to our board of directors with the approval (either by specific vote or by approval by our board of directors in our proxy statement in which such member was named as a nominee for election as a director without objection by our board of directors to such nomination) of a majority of the continuing directors who were members of our board of directors at the time of such nomination, election or appointment.
“ investment grade ” means a rating of Baa3 or better by Moody’s (or its equivalent under any successor rating categories of Moody’s); a rating of BBB- or better by S&P (or its equivalent under any successor rating categories of S&P); and the equivalent investment grade credit rating from any additional rating agency or rating agencies selected by us.
“ Moody’s ” means Moody’s Investors Service Inc.
“ rating agency ” means (1) each of Moody’s and S&P; and (2) if either of Moody’s or S&P ceases to rate the notes or fails to make a rating of the notes publicly available, a “nationally recognized statistical rating organization” within the meaning of Section 3(a)(62) of the Exchange Act, selected by us (as certified by a resolution of our board of directors or authorized committee thereof) as a replacement agency for Moody’s or S&P, or both, as the case may be.
“ rating category ” means (i) with respect to Moody’s, any of the following categories: Baa, Ba, B, Caa, Ca, C and D (or equivalent successor categories); (ii) with respect to S&P, any of the following categories: BBB, BB,
 
S-40

Table of Contents
B, CCC, CC, C and D (or equivalent successor categories); and (iii) the equivalent of any such category of Moody’s or S&P used by another rating agency. In determining whether the rating of the notes has decreased by one or more gradations, gradations within rating categories (1, 2 and 3 for Moody’s; + and - for S&P; or the equivalent gradations for another rating agency) shall be taken into account (e.g., with respect to S&P, a decline in a rating from BB+ to BB, as well as from BB- to B+, will constitute a decrease of one gradation).
“ ratings event ” means, with respect to a series of notes, the occurrence of the events described in (a) or (b) below during the period commencing on the date of our first public announcement of any change of control (or pending change of control) (the “rating date”) and ending 60 days following consummation of such change of control (which period shall be extended so long as the rating of the notes is under publicly announced consideration for a possible downgrade by any of the rating agencies): (a) in the event the applicable series of notes are rated by both rating agencies on the rating date as investment grade, the rating of such notes shall be reduced so that such notes are rated below investment grade by both rating agencies or (b) in the event the applicable series of notes (1) are rated investment grade by one rating agency and below investment grade by the other rating agency on the rating date, the rating of such notes by such rating agency rating such notes as investment grade shall be decreased by one or more gradations (including gradations within rating categories, as well as between rating categories) so that such notes are then rated below investment grade by both rating agencies or (2) are rated below investment grade by both rating agencies on the rating date, the rating of such notes by either rating agency shall be decreased by one or more gradations (including gradations within rating categories, as well as between rating categories).
“ S&P ” means Standard & Poor’s Ratings Services, a division of The McGraw-Hill Companies, Inc.
“ voting stock ” of any specified “person” (as that term is used in Section 13(d)(3) of the Exchange Act) as of any date means the capital stock of such person that is at the time entitled to vote generally in the election of the board of directors of such person.
Certain Covenants
Except as set forth below, neither we nor any of our subsidiaries will be restricted by the indenture from:
 
 	•	 	incurring any indebtedness or other obligation;	
 
 	•	 	paying dividends or making distributions on our capital stock or the capital stock of our subsidiaries; or	
 
 	•	 	purchasing or redeeming our capital stock or the capital stock of our subsidiaries.	
In addition, we will not be required to maintain any financial ratios or specified levels of net worth or liquidity or to repurchase or redeem or otherwise modify the terms of the notes upon a change of control or other events involving us or any of our subsidiaries which may adversely affect the creditworthiness of the notes, except to the limited extent provided under “—Purchase of Notes upon a Change of Control Repurchase Event.” Among other things, the indenture will not contain covenants designed to afford holders of the notes any protections in the event of a highly leveraged or other transaction involving us that may adversely affect holders of the notes, except to the limited extent provided under “—Purchase of Notes upon a Change of Control Repurchase Event.”
The indenture will contain the following principal covenants. Capitalized terms used in this subsection (“—Certain Covenants”) are defined below under “—Certain Definitions.”
Limitation on Liens
We will not incur, nor will we permit any of our wholly owned U.S. subsidiaries to incur, any Liens upon any property of ours or any of our wholly owned U.S. subsidiaries, whether now owned or hereafter created or
 
S-41

acquired, in order to secure indebtedness of us or any of our wholly owned U.S. subsidiaries, in each case, unless prior to or at the same time, the notes are equally and ratably secured with such secured indebtedness until such time as such indebtedness is no longer secured by such Lien.
The foregoing restriction does not apply to:
 
 	(1)	Liens on property or indebtedness existing with respect to any person at the time such person becomes our subsidiary or a subsidiary of any of our subsidiaries, provided that such Lien was not incurred in anticipation of such person becoming a subsidiary;	
 
 	(2)	Liens on property or indebtedness existing at the time of acquisition by us or any of our subsidiaries or a subsidiary of any of our subsidiaries of such property or indebtedness (which may include property previously leased by us or any of our subsidiaries and leasehold interests on such property, provided that the lease terminates prior to or upon the acquisition) or Liens on property or indebtedness to secure the payment of all or any part of the purchase price of such property or indebtedness, or Liens on property or indebtedness to secure any indebtedness incurred prior to, at the time of, or within 12 months after, the latest of the acquisition of such property or indebtedness or, in the case of property, the completion of construction, the completion of improvements or the commencement of substantial commercial operation of such property for the purpose of financing all or any part of the purchase price of the property and related costs and expenses, the construction or the making of the improvements;	
 
 	(3)	Liens securing our indebtedness or the indebtedness of any of our subsidiaries owing to us or any of our subsidiaries;	
 
 	(4)	Liens existing on the date of the initial issuance of the notes (other than any additional notes);	
 
 	(5)	Liens on property or assets of a person existing at the time such person is merged into or consolidated with us or any of our subsidiaries, at the time such person becomes our subsidiary, or at the time of a sale, lease or other disposition of all or substantially all of the properties or assets of a person to us or any of our subsidiaries, provided that such Lien was not incurred in anticipation of the merger, consolidation, sale, lease, other disposition or other such transaction;

 	(7)	Liens created to secure the notes;	
 
 	(8)	Liens imposed by law or arising by operation of law, including, without limitation, landlords’, mailmen’s, suppliers’, vendors’, carriers’, warehousemen’s and mechanic’s Liens and other similar Liens, Liens for master’s and crew’s wages and other similar laws, arising in the ordinary course of business, in each case for sums not yet overdue by more than 60 calendar days or being contested in good faith by appropriate proceedings or other Liens arising out of judgments or awards against such person with respect to which such person shall then be proceeding with an appeal or other proceedings for review and Liens arising solely by virtue of any statutory or common law provision relating to banker’s Liens, rights of set-off or similar rights and remedies as to deposit accounts or other funds maintained with a creditor depository institution;	
 
 	(9)	Liens for taxes, assessments or other governmental charges or levies on property not yet due or payable or subject to penalties for non-payment or which are being contested in good faith by appropriate proceedings;	
 
 	(10)	Liens to secure the performance of obligations with respect to statutory or regulatory requirements, bids, trade contracts, leases, statutory obligations, surety and appeal bonds, performance or return-of-money bonds and other obligations of a like nature;	
 
 	(11)	Permitted Liens; or

S-42

Table of Contents

 	other costs associated with any such extension, renewal or replacement); provided, however, that any Liens permitted by any of clauses (1) through (11) shall not extend to or cover any of our property or the property of any of our subsidiaries, as the case may be, other than the property specified in such clauses and improvements to such property.	
Notwithstanding the restrictions set forth in the preceding paragraph, we and our wholly owned U.S. subsidiaries will be permitted to incur indebtedness secured by Liens which would otherwise be subject to the foregoing restrictions without equally and ratably securing the notes, provided that, after giving effect to such indebtedness, the aggregate amount of all indebtedness secured by Liens (not including Liens permitted under clauses (1) through (12) above), together with all attributable debt outstanding pursuant to the second paragraph of the “—Limitation on Sale and Leaseback Transactions” covenant described below, does not exceed 15% of Consolidated Total Assets calculated as of the date of the creation or incurrence of the Lien. We and our wholly owned U.S. subsidiaries may also, without equally and ratably securing the notes, create or incur Liens that renew, substitute or replace (including successive renewals, substitutions or replacements), in whole or in part, any Lien permitted pursuant to the preceding sentence.
Limitation on Sale and Leaseback Transactions
We will not, nor will we permit any of our wholly owned U.S. subsidiaries to, enter into any sale and leaseback transaction for the sale and leasing back of any property, whether now owned or hereafter acquired, unless:
 
 	(1)	such transaction was entered into prior to the date of the initial issuance of the notes (other than any additional notes);	
 
 	(2)	such transaction was for the sale and leasing back to us or any of our wholly owned U.S. subsidiaries of any property by one of our subsidiaries;	
 
 	(3)	such transaction involves a lease for not more than three years (or which may be terminated by us or our subsidiaries within a period of not more than three years);	
 
 	(4)	we would be entitled to incur indebtedness secured by a Lien with respect to such sale and leaseback transaction without equally and ratably securing the notes pursuant to the second paragraph of the “—imitation on Liens” covenant described above;	
 
 	(5)	such transaction was for the sale and leasing back to us or any of our subsidiaries of the Sunnyvale Campus; or	
 
 	(6)	we apply an amount equal to the net proceeds from the sale of such property to the purchase of other property or assets used or useful in our business or to the retirement of long-term indebtedness within 12 months before or after the effective date of any such sale and leaseback transaction, provided that, in lieu of applying such amount to the retirement of long-term indebtedness, we may deliver debt securities (which may include the notes) to the applicable trustee for cancellation, such debt securities to be credited at the cost thereof to it.	
Notwithstanding the restrictions set forth in the preceding paragraph, we and our wholly owned U.S. subsidiaries may enter into any sale and leaseback transaction which would otherwise be subject to the foregoing restrictions, if after giving effect thereto the aggregate amount of all attributable debt with respect to such transactions (not including attributable debt permitted under clauses (1) through (6) of the preceding paragraph), together with all indebtedness outstanding pursuant to the third paragraph of the “—Limitation on Liens” covenant described above, does not exceed 15% of Consolidated Total Assets calculated as of the closing date of the sale and leaseback transaction.
 
S-43

Table of Contents
Merger, Consolidation or Sales of Assets
Under the terms of the indenture, we may consolidate with or merge into another entity or sell, convey, transfer, lease or otherwise dispose of all or substantially all of our property or assets to any other person or entity, provided that:
 
 	(1)	we are the continuing entity, or the successor entity formed from the consolidation or merger or the entity that received the transfer of or leases the assets is a corporation organized and validly existing under the laws of the United States, any state thereof or the District of Columbia and expressly assumes, by a supplemental indenture, all of our obligations under the notes and the indenture;	
 
 	(2)	immediately after giving effect to the transaction, no event of default shall have occurred and be continuing under the indenture; and	
 
 	(3)	we or the continuing entity deliver to the trustee an officer’s certificate and legal opinion stating that the transaction and the supplemental indenture complies with this covenant and that all conditions precedent in the indenture relating to the transaction have been satisfied.	
Upon satisfaction of the foregoing conditions, the surviving person shall succeed to, and be substituted for, and may exercise every right and power of us under the indenture and we will be released from all obligations and covenants under the indenture and notes; provided that, in the case of a lease of all or substantially all of our assets, we will not be released from any of the obligations or covenants under the indenture and the notes.
Events of Default
Each of the following is an “event of default” under the indenture for a series of notes:
 
 	(1)	a failure to pay principal of or premium, if any, on any note of such series, when due at its stated maturity date, upon optional redemption or otherwise;	
 
 	(2)	a failure to pay interest on any note of such series, for 30 days after the date payment is due and payable, if the time of payment has not been extended or deferred;	
 
 	(3)	a failure by us to comply with any covenant relating to the notes of such series, and the failure to comply continues for a period of 60 days after written notice to us by the trustee or to us and the trustee by the holders of 25% or more in aggregate principal amount of the outstanding notes of that series;	
 
 	(4)	a failure by us to repurchase notes tendered for repurchase following the occurrence of a change of control repurchase event in conformity with the covenant set forth under “Purchase of Notes upon a Change of Control Repurchase Event;”	
 
 	(5)	(a) a failure to make any payment at maturity, including any applicable grace period, on any of our indebtedness (other than indebtedness we owe to any of our subsidiaries) outstanding in an amount in excess of $100 million and continuance of this failure to pay or (b) a default on any of our indebtedness (other than indebtedness we owe to any of our subsidiaries), which default results in the acceleration of such indebtedness in an amount in excess of $100 million without such indebtedness having been discharged or the acceleration having been cured, waived, rescinded or annulled, in the case of clause (a) or (b) above, for a period of 30 days after written notice thereof to us by the trustee or to us and the trustee by the holders of not less than 25% in principal amount of outstanding notes (including any additional notes); provided, however, that if any failure, default or acceleration referred to in clause (a) or (b) above ceases or is cured, waived, rescinded or annulled, then the event of default will be deemed cured; and	
 
 	(6)	the occurrence of various events of bankruptcy, insolvency or reorganization involving us as provided in the indenture.	
If an event of default with respect to the notes occurs and is continuing, then the trustee or the holders of not less than 25% in aggregate principal amount of the outstanding notes of such series, may, by a notice in writing
 
S-44

Table of Contents
to us (and to the trustee if given by the holders), declare to be due and payable immediately the principal of, and accrued and unpaid interest, if any, on the applicable notes. In the case of an event of default resulting from certain events of bankruptcy, insolvency or reorganization, the principal (or such specified amount) of and accrued and unpaid interest, if any, on all outstanding notes will become and be immediately due and payable without any declaration or other act on the part of the trustee or any holder of notes. At any time after a declaration of acceleration with respect to the notes has been made, but before a judgment or decree for payment of the money due has been obtained by the trustee, the holders of a majority in aggregate principal amount of the outstanding notes of such series may rescind and annul the acceleration if all events of default, other than the non-payment of accelerated principal and interest, if any, with respect to the notes, have been cured or waived as provided in the indenture. The holders of a majority in aggregate principal amount of the outstanding notes of such series also have the right to waive past defaults, other than the nonpayment of principal or interest, if any, on any such outstanding note, or in respect of a covenant or a provision that cannot be modified or amended without the consent of all holders of the applicable notes.
The indenture provides that the trustee will be under no obligation to exercise any of its rights or powers under the indenture at the request of any holder of notes, unless the trustee receives indemnity satisfactory to it against any loss, liability or expense. Subject to certain rights of the trustee, the holders of a majority in principal amount of the outstanding notes of a series will 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 with respect to such notes.
No holder of any note will have any right to institute any proceeding, judicial or otherwise, with respect to the indenture or for the appointment of a receiver or trustee, or for any remedy under the indenture, unless:
 
 	•	 	that holder has previously given to the trustee written notice of a continuing event of default with respect to such series of notes;	
 
 	•	 	the holders of at least 25% in aggregate principal amount of the outstanding notes of such series have made written request, and offered indemnity reasonably satisfactory to the trustee, to the trustee to institute the proceeding as trustee; and	
 
 	•	 	the trustee has not instituted the proceeding, and has not received from the holders of a majority in aggregate principal amount of the outstanding notes of such series, a direction inconsistent with that request and has failed to institute the proceeding within the preceding 60 days.	
Notwithstanding the foregoing, the holder of any note will have an absolute and unconditional right to receive payment of the principal of, premium and any interest on that note on or after the due dates expressed in that note and to institute suit for the enforcement of such payment.
The trustee will, within 45 days after any default occurs, give notice of the default to the holders of the notes of that series, unless the default was already cured or waived. Unless there is a default in paying principal, interest or any premium when due, the trustee can withhold giving notice to the holders if it determines in good faith that the withholding of notice is in the interest of the holders of such notes.
We are required to furnish to the trustee an annual statement as to compliance with all conditions and covenants under the indenture.
Certain Definitions
The indenture contains the following defined terms:
“ attributable debt ” means, with respect to any sale and leaseback transaction, at the time of determination, the lesser of:

In the case of any lease which is terminable by the lessee upon the payment of a penalty, such present value shall be the lesser of (i) the present value determined assuming termination upon the first date such lease may be terminated (in which case the present value shall also include the amount of the penalty, but shall not include any rent that would be required to be paid under such lease subsequent to the first date upon which it may be terminated) or (ii) the present value assuming no such termination.

Payment and Transfer or Exchange
Principal of and premium, if any, and interest on the notes will be payable, and the notes may be exchanged or transferred, at the office or agency we maintain for such purpose (which initially will be the corporate trust office of the trustee). Payment of principal of and premium, if any, and interest on a global note registered in the name of or held by The Depository Trust Company (“DTC”) or its nominee will be made in immediately available funds to DTC or its nominee, as the case may be, as the registered holder of such global note. If the notes are no longer represented by a global note, payment of interest on certificated notes in definitive form may, at our option, be made by (i) check mailed directly to holders at their registered addresses or (ii) upon request of any holder of at least $1,000,000 principal amount of notes, wire transfer to an account located in the United States maintained by the payee. See “—Book-entry; Delivery and Form; Global Notes” below.
A holder may transfer or exchange any certificated notes in definitive form at the same location set forth in the preceding paragraph. No service charge will be made for any registration of transfer or exchange of notes, but we may require payment of a sum sufficient to cover any transfer tax or other similar governmental charge payable in connection therewith. We are not required to transfer or exchange any note selected for redemption during a period of 15 days before the electronic delivery or mailing of a notice of redemption of notes to be redeemed.
The registered holder of a note will be treated as the owner of that note for all purposes.
All amounts of principal of and premium, if any, and interest on the notes paid by us that remain unclaimed two years after such payment was due and payable will be repaid to us, and the holders of such notes will thereafter look solely to us for payment.
Same-day Settlement and Payment
The notes will trade in the same-day funds settlement system of DTC until maturity or until we issue the notes in certificated form. DTC will therefore require secondary market trading activity in the notes to settle in immediately available funds. We can give no assurance as to the effect, if any, of settlement in immediately available funds on trading activity in the notes.

Book-entry; Delivery and Form; Global Notes
General
The notes will be issued in registered, global form, in minimum denominations of $2,000 with integral multiples of $1,000 thereof. Initially, the notes will be represented by one or more permanent global certificates (the “global notes”) (which may be subdivided) in definitive, fully registered form without interest coupons. The global notes will be issued on the issue date only against payment in immediately available funds.
The global notes will be deposited upon issuance with the trustee as custodian for DTC in New York, New York, and registered in the name of Cede & Co. (DTC’s partnership nominee) or another DTC nominee for credit to an account of a direct or indirect participant in DTC, as described below under “—Depositary Procedures.”
Except as set forth below, the global notes may be transferred, in whole and not in part, only to another nominee of DTC or to a successor of DTC or its nominee. Beneficial interests in the global notes may not be exchanged for notes in certificated form except in the limited circumstances described below under “—Exchange of Book-Entry Notes for Certificated Notes.”
Transfers of beneficial interests in the global notes will be subject to the applicable rules and procedures of DTC and its direct or indirect participants (including, if applicable, those of Euroclear System (“Euroclear”) and Clearstream Banking S.A. (“Clearstream”)), which may change from time to time. DTC has advised as follows: DTC is a limited-purpose trust company organized under New York Banking Law, a “banking organization” within the meaning of the New York Banking Law, a member of the Federal Reserve System, a “clearing corporation” within the meaning of the New York Uniform Commercial Code and a “clearing agency” registered pursuant to the provisions of Section 17A of the Exchange Act. DTC was created to hold securities of institutions that have accounts with DTC (“participants”) and to facilitate the clearance and settlement of securities transactions among its participants in such securities through electronic book-entry changes in accounts of the participants, thereby eliminating the need for physical movement of securities certificates. DTC’s participants include securities brokers and dealers (which may include the initial purchasers), banks, trust companies, clearing corporations and certain other organizations. Access to DTC’s book-entry system is also available to others such as banks, brokers, dealers and trust companies that clear through or maintain a custodial relationship with a participant, whether directly or indirectly.
Depositary Procedures
The following description of the operations and procedures of DTC, Euroclear and Clearstream is provided solely as a matter of convenience. These operations and procedures are solely within the control of DTC and are subject to changes by it. We and the trustee do not take any responsibility for these operations and procedures and urge investors to contact DTC or its participants directly to discuss these matters.
DTC has advised us that it is a limited-purpose trust company created to hold securities for its participating organizations, referred to as “participants,” and to facilitate the clearance and settlement of transactions in those securities among DTC’s participants through electronic book-entry changes in accounts of its participants, thereby eliminating the need for physical movement of securities certificates. DTC’s participants include securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations some of whom (and/or their representatives) own DTC. Access to DTC’s system is also available to other entities such as banks, brokers, dealers, trust companies and clearing corporations that clear through or maintain a custodial relationship with a DTC participant, either directly or indirectly, which entities are referred to as “indirect participants.” Persons who are not DTC participants may beneficially own securities held by or on behalf of DTC only through participants or indirect participants. DTC has no knowledge of the identity of beneficial owners of securities held by or on behalf of DTC. DTC’s records reflect only the identity of its participants to whose accounts securities are credited. The ownership interests and transfer of ownership interests of each beneficial owner of each security held by or on behalf of DTC are recorded on the records of DTC’s participants and indirect participants.
 
S-49

Table of Contents
Pursuant to the procedures established by DTC:
 
 	•	 	upon deposit of the global notes, DTC will credit the accounts of its participants designated by the underwriters with portions of the principal amount of the global notes; and	
 
 	•	 	ownership of such interests in the global notes will be shown on, and the transfer of ownership of these interests will be effected only through, records maintained by DTC (with respect to the participants) or by the participants and the indirect participants (with respect to other owners of beneficial interests in the global notes).	
Investors in the global notes who are participants in DTC’s system may hold their interests therein directly through DTC. Investors in the global notes who are not participants may hold their interests therein indirectly through organizations which are participants in such system. Euroclear and Clearstream may hold interests in the global notes on behalf of their participants through customers’ securities accounts in their respective names on the books of their respective depositories, which are Euroclear Bank S.A./N.V., as operator of Euroclear, and Citibank, N.A., as operator of Clearstream. All interests in the global notes, including those held through Euroclear or Clearstream, will be subject to the procedures and requirements of DTC. Those interests held through Euroclear or Clearstream may also be subject to the procedures and requirements of such systems. The laws of some states require that certain persons take physical delivery of certificates evidencing securities they own. Consequently, the ability to transfer beneficial interests in the global notes to such persons will be limited to that extent. Because DTC can act only on behalf of its participants, which in turn act on behalf of indirect participants, the ability of beneficial owners of interests in the global notes to pledge such interests to persons or entities that do not participate in the DTC system, or otherwise take actions in respect of such interests, may be affected by the lack of a physical certificate evidencing such interests.
Except as described below, owners of interests in the global notes will not have notes registered in their names, will not receive physical delivery of notes in certificated form and will not be considered the registered owners or “holders” thereof under the indenture for any purpose.
Payments in respect of the principal of, and interest and premium, if any, on a global note registered in the name of DTC or its nominee will be payable to DTC in its capacity as the registered holder under the indenture. Under the terms of the indenture, we and the trustee will treat the persons in whose names the notes, including the global notes, are registered as the owners thereof for the purpose of receiving such payments and for any and all other purposes.
Consequently, neither we nor the trustee nor any of our respective agents has or will have any responsibility or liability for:
 
 	•	 	any aspect of DTC’s records or any participant’s or indirect participant’s records relating to or payments made on account of beneficial ownership interests in the global notes, or for maintaining, supervising or reviewing any of DTC’s records or any participant’s or indirect participant’s records relating to the beneficial ownership interests in the global notes; or	
 
 	•	 	any other matter relating to the actions and practices of DTC or any of its participants or indirect participants.	
DTC has advised us that its current practice, upon receipt of any payment in respect of securities such as the notes (including principal and interest), is to credit the accounts of the relevant participants with the payment on the payment date unless DTC has reason to believe it will not receive payment on such payment date. The account of each relevant participant is credited with an amount proportionate to the amount of its interest in the principal amount of the global notes as shown on the records of DTC. Payments by the participants and the indirect participants to the beneficial owners of notes will be governed by standing instructions and customary practices, and will be the responsibility of the participants or the indirect participants and will not be the responsibility of DTC, the trustee or us. Neither we nor the trustee will be liable for any delay by DTC or any of
 
S-50

Table of Contents
its participants in identifying the beneficial owners of the notes, and we and the trustee may conclusively rely on and will be protected in relying on instructions from DTC or its nominee for all purposes.
Transfers between participants in DTC will be effected in accordance with DTC’s procedures, and will be settled in same-day funds. Transfers between participants in Euroclear and Clearstream will be effected in accordance with their respective rules and operating procedures. Subject to compliance with the transfer restrictions applicable to the notes described herein, cross-market transfers between the participants in DTC, on the one hand, and Euroclear or Clearstream participants, on the other hand, will be effected through DTC in accordance with DTC’s rules on behalf of Euroclear or Clearstream, as the case may be, by its respective depositary; however, such cross-market transactions will require delivery of instructions to Euroclear or Clearstream, as the case may be, by the counterparty in such system in accordance with the rules and procedures and within the established deadlines (Brussels time) of such system. Euroclear or Clearstream, as the case may be, will, if the transaction meets its settlement requirements, deliver instructions to its respective depositary to take action to effect final settlement on its behalf by delivering or receiving interests in the relevant global note in DTC, and making or receiving payment in accordance with normal procedures for same-day funds settlement applicable to DTC. Euroclear participants and Clearstream participants may not deliver instructions directly to the depositories for Euroclear or Clearstream.
DTC has advised us that it will take any action permitted to be taken by a holder of notes only at the direction of one or more participants to whose account DTC has credited the interests in the global notes and only in respect of such portion of the aggregate principal amount of the notes as to which such participant or participants has or have given such direction.
Although DTC, Euroclear and Clearstream have agreed to the procedures described above to facilitate transfers of interests in the global notes among participants in DTC, Euroclear and Clearstream, they are under no obligation to perform or to continue to perform those procedures, and those procedures may be discontinued or changed at any time. Neither we nor the trustee will have any responsibility for the performance by DTC, Euroclear or Clearstream or their respective participants or indirect participants of their respective obligations under the rules and procedures governing their operations.
Exchange of Book-Entry Notes for Certificated Notes
The global notes are exchangeable for certificated notes in definitive, fully registered form without interest coupons only in the following limited circumstances:
 
 	•	 	DTC (1) notifies us that it is unwilling or unable to continue as depositary for the global notes and we fail to appoint a successor depositary within 90 days or (2) has ceased to be a clearing agency registered under the Exchange Act; or	
 
 	•	 	we notify the trustee in writing that we have elected to cause the issuance of certificated notes under the indenture.	
In all cases, certificated notes delivered in exchange for any global notes or beneficial interests therein will be registered in the names, and issued in any approved denominations, requested by or on behalf of DTC (in accordance with its customary procedures).
Payment and Paying Agents
Payments on the global notes will be made in U.S. dollars by wire transfer. If we issue definitive notes, the holders of definitive notes will be able to receive payments of principal of and interest on their notes at the office of our paying agent. Payment of principal of a definitive note may be made only against surrender of the note to our paying agent. We have the option, however, of making payments of interest by wire transfer or by mailing checks to the address of the holder appearing in the register of note holders maintained by the registrar.
 
S-51

Table of Contents
We will make any required interest payments to the person in whose name a note is registered at the close of business on the record date for the interest payment.
The trustee will be designated as our paying agent for payments on the notes. We may at any time designate additional paying agents, rescind the designation of any paying agent or approve a change in the office through which any paying agent acts.
Notices
Any notices required to be given to the holders of the notes will be given to DTC, as the registered holder of the global notes. In the event that the global notes are exchanged for notes in definitive form, notices to holders of the notes will be sent electronically or mailed by first-class mail, postage prepaid, to the addresses that appear on the register of noteholders maintained by the registrar.
The Trustee
The Bank of New York Mellon Trust Company, N.A. will be the trustee under the indenture. The trustee’s current address is 2 North LaSalle Street, Chicago, IL 60602, Attn: Corporate Trust Administration. The trustee is one of a number of banks with which we maintain ordinary banking relationships.
The trustee shall be under no obligation to exercise any of the rights or powers vested in it by the indenture at the request or direction of any of the holders pursuant to the indenture, unless such holders shall have offered to the trustee security or indemnity satisfactory to the trustee against the costs, expenses and liabilities which might be incurred by it in compliance with such request or direction.

Table of Contents
 MATERIAL U.S. FEDERAL INCOME TAX CONSIDERATIONS
This section is a discussion of the material U.S. federal income tax considerations relating to the purchase, ownership, and disposition of the notes. This summary does not provide a complete analysis of all potential tax considerations. The information provided below is based on the Internal Revenue Code of 1986, as amended (the “Code”), Treasury regulations promulgated thereunder, rulings, judicial decisions and other U.S. federal income tax authorities, all as of the date hereof, and all of which are subject to change or differing interpretations, possibly with retroactive effect. There can be no assurances that the Internal Revenue Service (the “IRS”) will not challenge one or more of the tax consequences described herein, and we have not obtained, nor do we intend to obtain, a ruling from the IRS with respect to the U.S. federal income tax consequences of purchasing, owning or disposing of the notes. The summary generally applies only to beneficial owners of the notes that purchase their notes in this offering for an amount equal to the issue price of the notes, which is the first price at which a substantial amount of the applicable series of notes is sold for money to investors (not including sales to bond houses, brokers or similar persons or organizations acting in the capacity of underwriters, placement agents or wholesalers), and that hold the notes as “capital assets” within the meaning of Section 1221 of the Code (generally, for investment). This discussion does not purport to deal with all aspects of U.S. federal income taxation that may be relevant to a particular beneficial owner in light of the beneficial owner’s circumstances (for example, persons subject to the alternative minimum tax or the Medicare contribution tax on net investment income, or a U.S. holder (as defined below) whose “functional currency” is not the U.S. dollar). Also, it is not intended to be wholly applicable to all categories of investors, some of which may be subject to special rules (such as dealers in securities or currencies, traders in securities that elect to use a mark-to-market method of accounting, banks, thrifts, regulated investment companies, real estate investment trusts, insurance companies, partnerships and entities that are classified as partnerships for U.S. federal income tax purposes and partners or members of such partnerships or entities, tax-exempt entities, tax-deferred or other retirement accounts, certain former citizens or residents of the United States, persons holding notes as part of a hedging, conversion or integrated transaction or a straddle, or persons deemed to sell notes under the constructive sale provisions of the Code). Finally, the summary does not describe the effects of the U.S. federal estate and gift tax laws or the effects of any applicable state, local or non-U.S. laws or tax treaties.
If a partnership (including for this purpose any entity or arrangement, domestic or foreign, treated as a partnership for U.S. federal income tax purposes) is a beneficial owner of a note, the tax treatment of a partner in the partnership will depend upon the status of the partner and the activities of the partnership. A beneficial owner of a note that is a partnership, and partners in such partnership, should consult their own tax advisors about the U.S. federal income tax consequences of purchasing, owning and disposing of the notes.
INVESTORS CONSIDERING THE PURCHASE OF NOTES SHOULD CONSULT THEIR OWN TAX ADVISORS REGARDING THE APPLICATION OF THE U.S. FEDERAL INCOME TAX LAWS TO THEIR PARTICULAR SITUATIONS AND THE CONSEQUENCES OF U.S. FEDERAL ESTATE AND GIFT TAX LAWS, STATE, LOCAL AND NON-U.S. LAWS, AND TAX TREATIES.
U.S. Holders
As used herein, the term “U.S. holder” means a beneficial owner of the notes that, for U.S. federal income tax purposes, is (1) an individual who is a citizen or resident of the United States, (2) a corporation, or an entity treated as a corporation for U.S. federal income tax purposes, created or organized in or under the laws of the United States, any state of the United States or the District of Columbia, (3) an estate the income of which is subject to U.S. federal income taxation regardless of its source, or (4) a trust if it (x) is subject to the primary supervision of a U.S. court and the control of one of more U.S. persons or (y) has a valid election in effect under applicable U.S. Treasury regulations to be treated as a U.S. person.
 
S-53

Table of Contents
Additional Amounts
We may be required to make payments to holders of the notes in addition to payments of principal and stated interest upon a change of control repurchase event. We believe there is only a remote possibility that we would be required to make such additional payments and/or that any such additional payments, if made, would be an incidental amount. Therefore, we do not intend to treat the notes as subject to the special rules governing certain contingent payment debt instruments. Our determination in this regard, while not binding on the IRS, is binding on U.S. holders unless they disclose their contrary position. If the IRS successfully asserted that the notes are subject to the contingent payment debt instrument rules, the timing, amount and character of income with respect to a note realized by a holder would be adversely different from those described below. The discussion herein assumes that the notes are not treated as contingent payment debt instruments.
Taxation of Interest
A U.S. holder will be required to recognize as ordinary income any stated interest paid or accrued on the notes, in accordance with its regular method of tax accounting.
If the principal amount of the notes exceeds their issue price by a statutory de minimis amount or more, the notes will have original issue discount (“OID”) for U.S. federal income tax purposes equal to such excess. A U.S. holder will be required to include the OID in gross income (as ordinary income) periodically over the term of the notes on a constant yield to maturity basis, before receipt of any cash attributable to such income, and regardless of the U.S. holder’s regular method of tax accounting. The notes are not expected to be issued with OID, and the discussion herein assumes that the notes will not have OID.
Sale, Exchange, Redemption or Other Disposition of the Notes
A U.S. holder generally will recognize capital gain or loss if the holder disposes of a note in a sale, exchange, redemption or other taxable disposition, including a satisfaction and discharge (as described in “Description of the Debt Securities—Satisfaction and discharge; defeasance” of the prospectus) within one year of maturity or redemption. The U.S. holder’s gain or loss generally will equal the difference between the proceeds received by the holder (other than amounts attributable to accrued but unpaid interest, which will be taxed as described below) and the holder’s tax basis in the note. The U.S. holder’s tax basis in the note generally will equal the amount the holder paid for the note. The portion of any proceeds that is attributable to accrued interest will not be taken into account in computing the U.S. holder’s capital gain or loss. Instead, that portion will be recognized as ordinary interest income to the extent that the U.S. holder has not previously included the accrued interest in income. The gain or loss recognized by a U.S. holder on a disposition of the note will be long-term capital gain or loss if the holder has held the note for more than one year, or short-term capital gain or loss if the holder has held the note for one year or less, at the time of the disposition. Long-term capital gains of non-corporate taxpayers currently are taxed at reduced rates. Short-term capital gains are taxed at ordinary income rates. The deductibility of capital losses is subject to limitation.
Non-U.S. Holders
The following discussion is limited to the U.S. federal income tax consequences relevant to a non-U.S. holder. A “non-U.S. holder” is a beneficial owner of the notes (other than a partnership or an entity or arrangement treated as a partnership for U.S. federal income tax purposes) that is not a U.S. holder. If a partnership (including for this purpose any entity or arrangement, domestic or foreign, treated as a partnership for U.S. federal income tax purposes) is a beneficial owner of a note, the tax treatment of a partner in the partnership will depend upon the status of the partner and the activities of the partnership. A beneficial owner of a note that is a partnership, and partners in such partnership, should consult their own tax advisors about the U.S. federal income tax consequences of purchasing, owning and disposing of the notes.

Taxation of Interest
Subject to the discussion below under “—Non-U.S. Holders—Income or Gains Effectively Connected with a U.S. Trade or Business,” payments of interest to non-U.S. holders are generally subject to U.S. federal income tax at a rate of 30 percent (or a reduced or zero rate under the terms of an applicable income tax treaty between the United States and the non-U.S. holder’s country of residence), collected by means of withholding by the payor. Payments of interest on the notes to most non-U.S. holders, however, will qualify as “portfolio interest,” and thus, subject to the discussion below regarding FATCA, will be exempt from U.S. federal income tax, including withholding of such tax, if the non-U.S. holders certify their nonresident status as described below. The portfolio interest exemption will not apply to payments of interest to a non-U.S. holder that:
 
 	•	 	owns, actually or constructively, applying certain attribution rules, shares of our stock representing at least 10 percent of the total combined voting power of all classes of our stock entitled to vote; or	
 
 	•	 	is a “controlled foreign corporation,” within the meaning of Section 957(a) of the Code, that is related, directly or indirectly, to us through sufficient stock ownership.	
In general, a foreign corporation is a controlled foreign corporation if more than 50 percent of its stock (by vote or value) is owned, actually or constructively, by one or more U.S. persons that each owns, actually or constructively, at least 10 percent of the corporation’s voting stock.
The portfolio interest exemption, reduction of the withholding rate pursuant to the terms of an applicable income tax treaty and an exemption from backup withholding described below under “—Backup Withholding and Information Reporting” apply only if the non-U.S. holder certifies its nonresident status. A non-U.S. holder can meet this certification requirement by providing a properly executed IRS Form W-8BEN, IRS Form W-8BEN-E or other applicable IRS Form W-8 to us or our paying agent prior to the payment. If the non-U.S. holder holds the note through a financial institution or other agent acting on the holder’s behalf, the holder will be required to provide appropriate documentation to the agent. The non-U.S. holder’s agent will then be required to provide certification to us or our paying agent, either directly or through other intermediaries. In addition, a non-U.S. holder that is seeking a reduction in withholding pursuant to the terms of an applicable income tax treaty will need to certify on IRS Form W-8BEN or IRS Form W-8BEN-E that it is eligible for the benefits of such treaty.
Sale, Exchange, Redemption or Other Disposition of Notes
Non-U.S. holders generally will not be subject to U.S. federal income or withholding tax on any gain realized on the sale, exchange, redemption or other disposition of notes (other than with respect to payments attributable to accrued interest, which will be taxed as described under “—Non-U.S. Holders—Taxation of Interest” above). However, the gain would be subject to U.S. federal income tax if:
 
 	•	 	the gain is effectively connected with the conduct by the non-U.S. holder of a U.S. trade or business (and, generally, if required by an applicable income tax treaty, the gain is attributable to a U.S. permanent establishment or fixed base maintained by the non-U.S. holder), in which case it would be subject to tax as described below under “—Non-U.S. Holders—Income or Gains Effectively Connected with a U.S. Trade or Business;” or	
 
 	•	 	the non-U.S. holder is an individual who is present in the United States for a period or periods aggregating 183 days or more in the year of the disposition and certain other conditions apply, in which case, except as otherwise provided by an applicable income tax treaty, the gain, which may be offset by certain U.S. source capital losses, would be subject to a flat 30 percent tax, even though the individual is not considered a resident of the United States.	
Income or Gains Effectively Connected with a U.S. Trade or Business
If any interest on the notes or gain from the sale, exchange, redemption or other disposition of the notes is effectively connected with a U.S. trade or business conducted by the non-U.S. holder, then the income or gain
 
S-55

Table of Contents
will be subject to U.S. federal income tax on a net income basis at the regular graduated rates and generally in the same manner applicable to U.S. holders. If the non-U.S. holder is eligible for the benefits of a tax treaty between the United States and the holder’s country of residence, any “effectively connected” income or gain generally will be subject to U.S. federal income tax only if it is also attributable to a permanent establishment or fixed base maintained by the holder in the United States. Payments of interest that are effectively connected with a U.S. trade or business (and, if a tax treaty applies, attributable to a permanent establishment or fixed base), and therefore included in the gross income of a non-U.S. holder, will not be subject to 30 percent withholding, provided that the holder claims exemption from withholding by timely filing a properly completed and executed IRS Form W-8ECI, or any applicable successor form, prior to the payment. If the non-U.S. holder is a corporation (including for this purpose any entity treated as a corporation for U.S. federal income tax purposes), that portion of its earnings and profits that is effectively connected with its U.S. trade or business generally also would be subject to a “branch profits tax.” The branch profits tax rate is generally 30 percent, although an applicable income tax treaty might provide for a lower rate.
Backup Withholding and Information Reporting
The Code and the Treasury regulations require those who make specified payments to report the payments to the IRS. Among the specified payments are interest and proceeds paid by brokers to their customers. This reporting regime is reinforced by “backup withholding” rules, which require the payor to withhold from payments subject to information reporting if the recipient has failed to provide a correct taxpayer identification number to the payor, furnished an incorrect identification number, or repeatedly failed to report interest or dividends on tax returns. The backup withholding rate is currently 28 percent.
Payments of interest to U.S. holders of notes and payments made to U.S. holders by a broker upon a sale of notes generally will be subject to information reporting, and generally will be subject to backup withholding, unless the holder (1) is an exempt payee, such as a corporation, or (2) provides the payor with a correct taxpayer identification number and complies with applicable certification requirements (for example, by submitting a property completed IRS Form W-9). If a sale is made through a foreign office of a foreign broker, however, the sale will generally not be subject to either information reporting or backup withholding. This exception may not apply if the foreign broker is owned or controlled by U.S. persons, or is engaged in a U.S. trade or business.
We must report annually to the IRS the interest paid to each non-U.S. holder and the tax withheld, if any, with respect to such interest, including any tax withheld pursuant to the rules described under “—Non-U.S. Holders—Taxation of Interest” above. Copies of these reports may be made available to tax authorities in the country where the non-U.S. holder resides. Payments to non-U.S. holders of interest on the notes may be subject to backup withholding unless the non-U.S. holder certifies its non-U.S. status on a properly executed IRS Form W-8BEN, IRS Form W-8BEN-E or other applicable IRS Form W-8. Payments made to non-U.S. holders by a broker upon a sale or other disposition of the notes will not be subject to information reporting or backup withholding as long as the non-U.S. holder certifies its non-U.S. status or otherwise establishes an exemption. However, if the non-U.S. holder holds the notes through certain foreign financial institutions, the financial institution may be required to report payments on the notes to the IRS. Non-U.S. holders should consult their tax advisors regarding the reporting requirements.
Any amounts withheld from a payment to a U.S. holder or non-U.S. holder of notes under the backup withholding rules generally can be credited against any U.S. federal income tax liability of the holder, provided the required information is timely furnished to the IRS.
Legislation and Guidance Relating to Foreign Accounts
Legislative and regulatory provisions commonly referred to as the Foreign Account Tax Compliance Act (“FATCA”) may impose a withholding tax on certain types of payments made to “foreign financial institutions” and certain other “non-financial foreign entities” as defined in the Code and applicable regulations. Accordingly,
 
S-56

Table of Contents
the entity through which our notes are held will affect the determination of whether such withholding is required. Under the FATCA provisions, a withholding tax of 30% is imposed on interest on the notes and, beginning January 1, 2019, on gross proceeds from the sale or other disposition of the notes paid to a foreign financial institution or other non-financial foreign entity (whether as beneficial owner or intermediary), unless (i) the foreign financial institution undertakes certain diligence and reporting obligations, (ii) the non-financial foreign entity either certifies it does not have any substantial U.S. owners or furnishes identifying information regarding each substantial U.S. owner and such entity meets certain other specified requirements or (iii) the foreign financial institution or non-financial foreign entity qualifies for an exemption from the withholding tax. Subject to the following sentence, if the payee is a foreign financial institution and an exemption does not apply, it must enter into an agreement with the U.S. Treasury requiring, among other things, that it undertake to identify accounts held by certain U.S. persons or U.S.-owned foreign entities, annually report certain information about such accounts, and withhold 30% on certain payments to account holders whose actions prevent it from complying with these reporting and other requirements. If the country in which a payee is resident has entered into an intergovernmental agreement with the United States regarding FATCA, such agreement may permit the payee to report to that country rather than the U.S. Treasury, and may obviate the need to enter into an agreement with the U.S. Treasury. Prospective investors should consult their tax advisors regarding this legislation.

 CERTAIN ERISA CONSIDERATIONS
Each fiduciary of a pension, profit-sharing or other employee benefit plan subject to the U.S. Employee Retirement Income Security Act of 1974, as amended (“ERISA”) (each, an “Employee Benefit Plan”), should consider the fiduciary standards of ERISA in the context of the Employee Benefit Plan’s particular circumstances before authorizing an investment in the notes. Among other factors, the fiduciary should consider whether the investment would satisfy the prudence and diversification requirements of ERISA and would be consistent with the documents and instruments governing the Employee Benefit Plan, and whether the investment would involve a prohibited transaction under Section 406 of ERISA or Section 4975 of the Code.
Section 406 of ERISA and Section 4975 of the Code prohibit Employee Benefit Plans, as well as individual retirement accounts and other arrangements that are subject to Section 4975 of the Code (collectively, “Plans”), from engaging in certain transactions involving “plan assets” with persons who are “parties in interest” under ERISA or “disqualified persons” under the Code with respect to the Plan. A violation of these prohibited transaction rules may result in excise taxes, penalties or other liabilities under ERISA or the Code for those persons and the fiduciary of the Plan, unless exemptive relief is available under an applicable statutory, regulatory or administrative exemption. Plans that are governmental plans (as defined in Section 3(32) of ERISA), certain church plans (as defined in Section 3(33) of ERISA) and non-U.S. plans (as described in Section 4(b)(4) of ERISA) (“Non-ERISA Arrangements”) are not subject to the prohibited transaction requirements of ERISA or the Code, but may be subject to similar provisions under other applicable federal, state, local, non-U.S. or other laws.
The acquisition or holding of the notes by a Plan or any entity whose underlying assets include “plan assets” by reason of any Plan’s investment in the entity (a “Plan Asset Entity”) with respect to which we, certain of our affiliates or the underwriters are, or become, a party in interest or disqualified person may result in a direct or indirect prohibited transaction under ERISA or the Code, unless the notes are acquired and held pursuant to an applicable statutory or administrative prohibited transaction exemption. The U.S. Department of Labor has issued five prohibited transaction class exemptions, or “PTCEs,” that may provide exemptive relief that may arise from the purchase or holding of the notes. These exemptions are: PTCE 84-14 (for certain transactions determined by independent qualified professional asset managers), PTCE 90-1 (for certain transactions involving insurance company pooled separate accounts), PTCE 91-38 (for certain transactions involving bank collective investment funds), PTCE 95-60 (for transactions involving certain insurance company general accounts), and PTCE 96-23 (for transactions managed by in-house asset managers). In addition, Section 408(b)(17) of ERISA and Section 4975(d)(20) of the Code provide limited relief from the prohibited transactions provisions of ERISA and the Code for certain transactions, provided that neither the issuer of securities offered hereby nor any of its affiliates (directly or indirectly) have or exercise any discretionary authority or control or render any investment advice with respect to the assets of any Plan involved in the transaction, and provided further that the Plan pays no more and receives no less than “adequate consideration” in connection with the transaction (the “service provider exemption”). There can be no assurance that all of the conditions of any such exemptions will be satisfied.
Because of the foregoing, the notes should not be acquired or held by any person investing “plan assets” of any Plan, Plan Asset Entity or otherwise, unless in each case the purchaser or holder is eligible for exemptive relief available under one or more of the PTCEs listed above or another applicable statutory or similar exemption.
Any purchaser or holder of the notes or any interest therein will be deemed to have represented to Juniper Networks, Inc. or any of its affiliates by its acquisition and holding of the notes offered hereby that it either (1) is not a Plan or Plan Asset Entity and is not purchasing or holding the notes on behalf of or with the assets of any Plan, or Plan Asset Entity, or (2) its purchase and holding the notes will not be prohibited transactions because they are covered by one of the PTCEs listed above, the “service provider exemption” or other statutory or
 
S-58

Table of Contents
administrative exemption from the prohibited transaction provisions of ERISA and the Code, or (3) it is a Non-ERISA Arrangement and its purchase and holding of the notes is not otherwise prohibited under any similar applicable law.
The foregoing discussion is general in nature and is not intended to be all inclusive. Due to the complexity of these rules and the penalties that may be imposed upon persons involved in non-exempt prohibited transactions, it is important that fiduciaries or other persons considering acquiring the notes on behalf of or with the assets of any Plan, Plan Asset Entity or Non-ERISA Arrangement consult with their counsel regarding the potential applicability of ERISA, Section 4975 of the Code and any similar laws to such investments, as well as the availability of exemptive relief under any of the PTCEs listed above or the service provider exemption, as applicable. Purchasers of notes have exclusive responsibility for ensuring that their purchase and holding of notes do not violate the fiduciary or prohibited transaction rules of ERISA or the Code or any applicable similar laws. The sale of any notes to a Plan, Plan Asset Entity or Non-ERISA Arrangement is in no respect a representation by us or any of our affiliates, representatives or underwriters that such (1) an investment meets all relevant legal requirements with respect to investments by any such Plans, Plan Asset Entities or Non-ERISA Arrangements generally or any particular Plan, Plan Asset Entity or Non-ERISA Arrangement or (2) investment is appropriate for such Plans, Plan Asset Entities or Non-ERISA Arrangements generally, or any particular Plan, Plan Asset Entity or Non-ERISA Arrangement.

The underwriters are offering the notes subject to their receipt and acceptance of the notes from us, prior sale and the underwriters’ right to reject any order in whole or in part. The underwriting agreement provides that the obligations of the several underwriters to pay for and accept delivery of the notes offered by this prospectus supplement are subject to the approval of certain legal matters by their counsel and to certain other conditions. The underwriters are obligated to take and pay for all of the notes offered by this prospectus supplement if any such notes are taken.
The underwriters initially propose to offer the notes directly to the public at the public offering prices set forth on the cover page of this prospectus supplement and may offer notes to certain dealers at a price that represents a concession not in excess of       % of the principal amount of the 20     notes and       % of the principal amount of the 20     notes. Any such dealers may resell any notes purchased from the underwriters to certain other brokers or dealers at a discount not to exceed       % of the principal amount of the 20     notes and       % of the principal amount of the 20     notes. After the initial offering of the notes, the offering prices and other selling terms may from time to time be varied by the representatives. The underwriters may offer and sell notes through certain of their affiliates.
The following table shows the underwriting discounts that we will pay to the underwriters in connection with this offering:

 	  	Paid by Us	 	
Per 20     note	  	 	        	% 	
Per 20     note	  	 	        	% 	
Total	  	$	            	  	
Expenses associated with this offering to be paid by us, other than underwriting discounts, are estimated to be approximately $            .
In connection with the offering of the notes, the underwriters may engage in transactions that stabilize, maintain or otherwise affect the prices of the notes. Specifically, the underwriters may overallot in connection with the offering of the notes, creating a syndicate short position. In addition, the underwriters may bid for, and purchase, notes in the open market to cover syndicate short positions or to stabilize the prices of the notes. The underwriters may also impose a penalty bid. This occurs when a certain underwriter repays to the underwriters a portion of the underwriting discount received by it because the representatives have repurchased notes sold by or for the account of such underwriter in stabilizing or short covering transactions. Finally, the underwriting syndicate may reclaim selling concessions allowed for distributing the notes in the offering of the notes, if the
 
S-60

Table of Contents
syndicate repurchases previously distributed notes in syndicate covering transactions, stabilization transactions or otherwise. Any of these activities may stabilize or maintain the market prices of the notes above independent market levels. The underwriters are not required to engage in any of these activities, and may end any of them at any time.
We have agreed to indemnify the several underwriters against certain liabilities, including liabilities under the Securities Act of 1933, as amended, or to contribute to payments which the underwriters may be required to make in respect of any such liabilities.
Prior to the offering, there have been no active markets for the notes. The underwriters have advised us that certain of the underwriters presently intend to make markets in the notes as permitted by applicable laws and regulations. Such underwriters are not obligated, however, to make the markets in the notes and any such market making may be discontinued at any time at the discretion of such underwriters. Accordingly, no assurance can be given as to the liquidity of, or trading markets for, the notes.
From time to time in the ordinary course of their respective businesses, certain of the underwriters and their affiliates have engaged in and may in the future engage in commercial banking, derivatives and/or investment banking transactions with us and our affiliates. In particular, affiliates of certain of the underwriters, including Barclays Capital Inc., Citigroup Global Markets Inc., J.P. Morgan Securities LLC and Merrill Lynch, Pierce, Fenner & Smith Incorporated, are participants in our $500.0 million unsecured revolving credit facility that expires in June 2019, for which such underwriters and their affiliates have been paid customary fees. Barclays Capital Inc., Citigroup Global Markets Inc., J.P. Morgan Securities LLC, Merrill Lynch, Pierce, Fenner & Smith Incorporated and UBS Securities LLC have provided, and continue to provide, various investment banking services for us and our subsidiaries and other affiliates, for which they received or will receive customary fees and expenses. In addition, from time to time in the ordinary course of business, certain of the underwriters and their affiliates are and have been customers of us and our affiliates.
In the ordinary course of their various business activities, the underwriters and certain of their affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (including bank loans) for their own account and for the accounts of their customers, and such investment and securities activities may involve securities and/or instruments of the issuer or its affiliates. If the underwriters or their affiliates have a lending relationship with us, certain of those underwriters or their affiliates may hedge their credit exposure to us consistent with their customary risk management policies. Typically, the 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 or the securities of our affiliates, including potentially the notes offered hereby. Any such credit default swaps or short positions could adversely affect future trading prices of the notes offered hereby. The underwriters and certain of their affiliates may also communicate independent investment recommendations, market color or trading ideas and/or publish or express independent research views in respect of such securities or instruments and may at any time hold, or recommend to clients that they acquire, long and/or short positions in such securities and instruments.

The Securities We May Offer
We may offer common stock, preferred stock, depositary shares, warrants, debt securities, purchase contracts and purchase units in one or more offerings and in any combination. This prospectus provides you with a general description of the securities we may offer. A prospectus supplement, which we will provide each time we offer securities, will describe the specific amounts, prices and terms of these securities.
Common Stock
Each holder of our common stock is entitled to one vote for each share on all matters to be voted upon by the stockholders, and there are no cumulative rights. Subject to any preferential rights of any outstanding preferred stock, holders of our common stock are entitled to receive ratably the dividends, if any, as may be declared from

Table of Contents
time to time by the board of directors out of funds legally available therefor. If there is a liquidation, dissolution or winding up of our company, holders of our common stock would be entitled to share in our assets remaining after the payment of liabilities and any preferential rights of any outstanding preferred stock.
Preferred Stock and Depository Shares
Under the terms of our amended and restated certificate of incorporation, our board of directors is authorized to issue shares of preferred stock in one or more series without stockholder approval. Our board of directors has the discretion to determine the rights, preferences, privileges and restrictions, including voting rights, dividend rights, conversion rights, redemption privileges and liquidation preferences, of each series of preferred stock.
We may also issue fractional shares of preferred stock that will be represented by depositary shares and depositary receipts.
Each series of preferred stock, depository shares or depository receipts, if issued, will be more fully described in the particular prospectus supplement that will accompany this prospectus, including redemption provisions, rights in the event of our liquidation, dissolution or winding up, voting rights and rights to convert into common stock. We have no present plans to issue any shares of preferred stock, depository shares or depository receipts nor are any shares of our preferred stock, depository shares or depository receipts presently outstanding.
Warrants
We may issue warrants for the purchase of common stock, preferred stock or debt securities. We may issue warrants independently or together with other securities.
Debt Securities
We may offer secured or unsecured obligations in the form of one or more series of senior or subordinated debt. The senior debt securities and the subordinated debt securities are together referred to in this prospectus as the “debt securities.” The subordinated debt securities generally will be entitled to payment only after payment of our senior debt. Senior debt generally includes all debt for money borrowed by us, except debt that is stated in the instrument governing the terms of that debt to be not senior to, or to have the same rank in right of payment as, or to be expressly junior to, the subordinated debt securities. We may issue debt securities that are convertible into shares of our common stock.
The senior and subordinated debt securities will be issued under separate indentures between us and a trustee. We have summarized the general features of the debt securities to be governed by the indentures. These indentures have been filed as exhibits to the registration statement of which this prospectus forms a part. We encourage you to read these indentures. Instructions on how you can get copies of these documents are provided under the heading “Where You Can Find More Information.”
Purchase Contracts and Purchase Units
We may issue purchase contracts and purchase units comprised of one or more of the other classes of securities issued by us as described in this prospectus in any combination.

 RATIO OF EARNINGS TO FIXED CHARGES
The following table sets forth our ratio of earnings to fixed charges on a historical basis for each of the periods indicated. You should read these ratios in connection with our consolidated financial statements, including the notes to those statements, incorporated by reference in this prospectus.

 	  	Six
Months
Ended
June 30,	 	  	Fiscal Year Ended December 31,	 	
 	  	2013	 	  	2012	 	  	2011	 	  	2010	 	  	2009	 	  	2008	 	
Ratio of earnings to fixed charges	  	 	6.4x	  	  	 	4.6x	  	  	 	9.2x	  	  	 	46.8x	  	  	 	19.7x	  	  	 	33.0x	  	
The ratio of earnings to fixed charges has been computed on a consolidated basis. “Earnings” consists of consolidated net income before income taxes plus fixed charges, net of capitalized interest, plus amortization of capitalized interest, reduced by the non-controlling interest in pre-tax income of subsidiaries that have not incurred fixed charges. “Fixed charges” consist of interest expense, capitalized interest, amortized premiums, discounts and capitalized expenses related to indebtedness as well as a portion of rental expense estimated to represent interest.
As of the date of this prospectus, we have not previously paid dividends on any shares of preferred stock, and consequently, our ratio of earnings to preferred share dividends and ratio of earnings to fixed charges would be identical.

 RISK FACTORS
An investment in our securities involves a high degree of risk. The prospectus supplement applicable to each offering of our securities will contain a discussion of the risks applicable to an investment in our securities. Prior to making a decision about investing in our securities, you should carefully consider the specific factors discussed under the heading “Risk Factors” in the applicable prospectus supplement, together with all of the other information contained or incorporated by reference in the prospectus supplement or appearing or incorporated by reference in this prospectus. You should also consider the risks, uncertainties and assumptions discussed under Item 1A, “Risk Factors,” in our Annual Report on Form 10-K for the fiscal year ended December 31, 2012, our Quarterly Report on Form 10-Q for the fiscal quarter ended March 31, 2013 and our Quarterly Report on Form 10-Q for the fiscal quarter ended June 30, 2013, all of which are incorporated herein by reference, and may be amended, supplemented or superseded from time to time by other reports we file with the SEC in the future and any prospectus supplement related to a particular offering. The risks and uncertainties we have described are not the only ones we face. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also affect our operations.
 FORWARD-LOOKING STATEMENTS
This prospectus, each prospectus supplement and the information incorporated by reference in this prospectus and each prospectus supplement contain certain statements that constitute “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. The words “anticipate,” “expect,” “target,” “seek,” “would,” “could,” “believe,” “goal,” “plan,” “intend,” “estimate,” “may,” “will,” and similar expressions and variations thereof are intended to identify forward-looking statements, but are not the exclusive means of identifying such statements. Those statements appear in this prospectus, any accompanying prospectus supplement and the documents incorporated herein and therein by reference, particularly in the sections entitled “Prospectus Summary,” “Risk Factors,” “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and “Business,” and include statements regarding the intent, belief or current expectations of the Company and management that are subject to known and unknown risks, uncertainties and assumptions.
This prospectus, any prospectus supplement and the information incorporated by reference in this prospectus and any prospectus supplement also contain statements that are based on the current expectations of our Company and management. You are cautioned that any such forward-looking statements are not guarantees of future performance and involve risks and uncertainties, and that actual results may differ materially from those projected in the forward-looking statements as a result of various factors.
Because forward-looking statements are inherently subject to risks and uncertainties, some of which cannot be predicted or quantified, you should not rely upon forward-looking statements as predictions of future events. The events and circumstances reflected in the forward-looking statements may not be achieved or occur and actual results could differ materially from those projected in the forward-looking statements. Except as required by applicable law, including the securities laws of the United States and the rules and regulations of the SEC, we do not plan to publicly update or revise any forward-looking statements contained herein after we distribute this prospectus, whether as a result of any new information, future events or otherwise.

 USE OF PROCEEDS
Unless otherwise indicated in the prospectus supplement, we will use the net proceeds from the sale of securities offered by this prospectus for general corporate purposes, which may include working capital, capital expenditures, other corporate expenses and acquisitions of complementary products, technologies or businesses. The timing and amount of our actual expenditures will be based on many factors, including cash flows from operations and the anticipated growth of our business. As a result, unless otherwise indicated in the prospectus supplement, our management will have broad discretion to allocate the net proceeds of the offerings. Pending their ultimate use, we intend to invest the net proceeds in investment-grade, interest-bearing instruments.

 DESCRIPTION OF CAPITAL STOCK
The following information describes our common stock and preferred stock, as well as certain provisions of our amended and restated certificate of incorporation and bylaws. This description is only a summary. You should also refer to our amended and restated certificate of incorporation and bylaws, which have been filed with the SEC as exhibits to our registration statement, of which this prospectus forms a part.
General
Our authorized capital stock consists of 1,000,000,000 shares of common stock with a par value of $0.00001 per share, and 10,000,000 shares of preferred stock with a par value of $0.00001 per share, all of which shares of preferred stock are undesignated. Our board of directors may establish the rights and preferences of the preferred stock from time to time. As of August 2, 2013, there were 506,838,542 shares of common stock issued and outstanding, held of record by 920 stockholders, although we believe that there may be a significantly larger number of beneficial owners of our common stock. We derived the number of stockholders by reviewing the listing of outstanding common stock recorded by our transfer agent as of August 2, 2013.
The following is a summary of the material provisions of the common stock and preferred stock provided for in our certificate of incorporation and bylaws. For additional detail about our capital stock, please refer to our certificate of incorporation and bylaws, each as amended.
Common Stock
Each holder of our common stock is entitled to one vote for each share on all matters to be voted upon by the stockholders and there are no cumulative rights. Subject to any preferential rights of any outstanding preferred stock, holders of our common stock are entitled to receive ratably the dividends, if any, as may be declared from time to time by the board of directors out of funds legally available therefor. If there is a liquidation, dissolution or winding up of our company, holders of our common stock would be entitled to share in our assets remaining after the payment of liabilities and any preferential rights of any outstanding preferred stock.
Holders of our common stock have no preemptive or conversion rights or other subscription rights, and there are no redemption or sinking fund provisions applicable to the common stock. The outstanding shares of common stock are fully paid and non-assessable. The rights, preferences and privileges of the holders of our common stock are subject to, and may be adversely affected by, the rights of the holders of shares of any series of preferred stock that we may designate and issue in the future.
Our common stock is listed on the New York Stock Exchange under the symbol “JNPR.” The transfer agent and registrar for the common stock is Wells Fargo Bank N.A., Shareowner Services. Its address is 1110 Centre Pointe Curve, Suite 101, Mendota Heights, Minnesota, 55120, and its telephone number is (800) 468-9716.
Preferred stock
The following description of preferred stock and the description of the terms of any particular series of preferred stock that we choose to issue hereunder and that will be set forth in the related prospectus supplement are not complete. These descriptions are qualified in their entirety by reference to our amended and restated certificate of incorporation and the certificate of designation relating to any series. The rights, preferences, privileges and restrictions of the preferred stock of each series will be fixed by the certificate of designation relating to that series. The prospectus supplement also will contain a description of certain United States federal income tax consequences relating to the purchase and ownership of the series of preferred stock that is described in the prospectus supplement.
Under the terms of our amended and restated certificate of incorporation, our board of directors is authorized to issue shares of preferred stock in one or more series without stockholder approval. Our board of directors has the
 
-7-

Table of Contents
discretion to determine the rights, preferences, privileges and restrictions, including voting rights, dividend rights, conversion rights, redemption privileges and liquidation preferences, of each series of preferred stock. There are no restrictions presently on the repurchase or redemption of any shares of our preferred stock.
The prospectus supplement for a series of preferred stock will specify:
 
 	•	 	the maximum number of shares;	
 
 	•	 	the designation of the shares;	
 
 	•	 	the annual dividend rate, if any, whether the dividend rate is fixed or variable, the date or dates on which dividends will accrue, the dividend payment dates, and whether dividends will be cumulative;	
 
 	•	 	the price and the terms and conditions for redemption, if any, including redemption at our option or at the option of the holders, including the time period for redemption, and any accumulated dividends or premiums;	
 
 	•	 	the liquidation preference, if any, and any accumulated dividends upon the liquidation, dissolution or winding up of our affairs;	
 
 	•	 	any sinking fund or similar provision, and, if so, the terms and provisions relating to the purpose and operation of the fund;	
 
 	•	 	the terms and conditions, if any, for conversion or exchange of shares of any other class or classes of our capital stock or any series of any other class or classes, or of any other series of the same class, or any other securities or assets, including the price or the rate of conversion or exchange and the method, if any, of adjustment;	
 
 	•	 	the voting rights; and	
 
 	•	 	any or all other preferences and relative, participating, optional or other special rights, privileges or qualifications, limitations or restrictions.	
The issuance of preferred stock will affect, and may adversely affect, the rights of holders of common stock. It is not possible to state the actual effect of the issuance of any shares of preferred stock on the rights of holders of common stock until the board of directors determines the specific rights attached to that preferred stock. The effects of issuing preferred stock could include one or more of the following:
 
 	•	 	restricting dividends on the common stock;	
 
 	•	 	diluting the voting power of the common stock;	
 
 	•	 	impairing the liquidation rights of the common stock; or	
 
 	•	 	delaying or preventing changes in control or management of our company.	
We have no present plans to issue any shares of preferred stock nor are any shares of our preferred stock presently outstanding. Preferred stock will be fully paid and nonassessable upon issuance.
Effect of Certain Provisions of our Amended and Restated Certificate of Incorporation and Bylaws and the Delaware Anti-Takeover Statute
Some provisions of Delaware law and our amended and restated certificate of incorporation and bylaws contain provisions that could make the following transactions more difficult:
 
 	•	 	acquisition of us by means of a tender offer;	
 
 	•	 	acquisition of us by means of a proxy contest or otherwise; or	
 
 	•	 	removal of our incumbent officers and directors.	
 
-8-

Table of Contents
Those provisions, summarized below, are expected to discourage coercive takeover practices and inadequate takeover bids and to promote stability in our management. These provisions are also designed to encourage persons seeking to acquire control of us to first negotiate with our board of directors.
Amended and Restated Certificate of Incorporation and Bylaws
Our amended and restated certificate of incorporation and our bylaws provide for the following:
 
 	•	 	Undesignated Preferred Stock.  The ability to authorize undesignated preferred stock makes it possible for our board of directors to issue one or more series of preferred stock with voting or other rights or preferences that could impede the success of any attempt to change control of our company. These and other provisions may have the effect of deferring hostile takeovers or delaying changes in control or management of our company.	
 
 	•	 	Stockholder Meetings.  Our charter documents provide that a special meeting of stockholders may be called only by resolution adopted by the board of directors, the chairman of the board, the president or the chief executive officer.	
 
 	•	 	Requirements for Advance Notification of Stockholder Nominations and Proposals . Our bylaws establish advance notice procedures with respect to stockholder proposals and the nomination of candidates for election as directors, other than nominations made by or at the direction of the board of directors or a committee of the board of directors.	
 
 	•	 	Limits on Ability of Stockholders to Act by Written Consent . We have provided in our certificate of incorporation that our stockholders may not act by written consent. This limit on the ability of our stockholders to act by written consent may lengthen the amount of time required to take stockholder actions. As a result, a holder controlling a majority of our capital stock would not be able to amend our bylaws or remove directors without holding a meeting of our stockholders called in accordance with our bylaws.	
 
 	•	 	Amendment of Certificate of Incorporation and Bylaws.  The amendment of the provisions of our amended and restated certificate of incorporation and bylaws related to the annual meeting of stockholders and special meetings of stockholders requires approval by holders of at least two-thirds of our outstanding capital stock entitled to vote generally in the election of directors.	
Delaware Anti-Takeover Statute
We are subject to Section 203 of the General Corporation Law of the State of Delaware, which prohibits a Delaware corporation from engaging in any business combination with any interested stockholder for a period of three years after the date that such stockholder became an interested stockholder, with the following exceptions:
 
 	•	 	before such date, the board of directors of the corporation approved either the business combination or the transaction that resulted in the stockholder becoming an interested stockholder;	
 
 	•	 	upon completion of the transaction that resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the transaction began, excluding for purposes of determining the voting stock outstanding (but not the outstanding voting stock owned by the interested stockholder) those shares owned (i) by persons who are directors and also officers and (ii) employee stock plans in which employee participants do not have the right to determine confidentially whether shares held subject to the plan will be tendered in a tender or exchange offer; or	
 
 	•	 	on or after such date, the business combination is approved by the board of directors and authorized at an annual or special meeting of the stockholders, and not by written consent, by the affirmative vote of at least 662/3% of the outstanding voting stock that is not owned by the interested stockholder.	
 
-9-

Table of Contents
In general, Section 203 defines business combination to include the following:
 
 	•	 	any merger or consolidation involving the corporation and the interested stockholder;	
 
 	•	 	any sale, lease, exchange, mortgage, transfer, pledge or other disposition of 10% or more of either the assets or outstanding stock of the corporation involving the interested stockholder;	
 
 	•	 	subject to certain exceptions, any transaction that results in the issuance or transfer by the corporation of any stock of the corporation to the interested stockholder;	
 
 	•	 	any transaction involving the corporation that has the effect of increasing the proportionate share of the stock of any class or series of the corporation beneficially owned by the interested stockholder; or	
 
 	•	 	the receipt by the interested stockholder of the benefit of any loans, advances, guarantees, pledges or other financial benefits by or through the corporation.	
In general, Section 203 defines interested stockholder as an entity or person who, together with affiliates and associates, beneficially owns, or within three years prior to the determination of interested stockholder status did own, 15% or more of the outstanding voting stock of the corporation.

 DESCRIPTION OF THE DEPOSITARY SHARES
General
At our option, we may elect to offer fractional shares of preferred stock, rather than full shares of preferred stock. If we do elect to offer fractional shares of preferred stock, we will issue receipts for depositary shares and each of these depositary shares will represent a fraction of a share of a particular series of preferred stock, as specified in the applicable prospectus supplement. Each owner of a depositary share will be entitled, in proportion to the applicable fractional interest in shares of preferred stock underlying that depositary share, to all rights and preferences of the preferred stock underlying that depositary share. These rights may include dividend, voting, redemption and liquidation rights.
The shares of preferred stock underlying the depositary shares will be deposited with a bank or trust company selected by us to act as depositary, under a deposit agreement by and among us, the depositary and the holders of the depositary receipts. The depositary will be the transfer agent, registrar and dividend disbursing agent for the depositary shares.
The depositary shares will be evidenced by depositary receipts issued pursuant to the depositary agreement. Holders of depositary receipts agree to be bound by the deposit agreement, which requires holders to take certain actions such as filing proof of residence and paying certain charges.
The summary of terms of the depositary shares contained in this prospectus is not complete, and is subject to modification in any prospectus supplement for any issuance of depositary shares. You should refer to the forms of the deposit agreement, our certificate of incorporation and the certificate of designation that are, or will be, filed with the SEC for the applicable series of preferred stock.
Dividends
The depositary will distribute cash dividends or other cash distributions, if any, received in respect of the series of preferred stock underlying the depositary shares to the record holders of depositary receipts in proportion to the number of depositary shares owned by those holders on the relevant record date. The relevant record date for depositary shares will be the same date as the record date for the preferred stock.
In the event of a distribution other than in cash, the depositary will distribute property received by it to the record holders of depositary receipts that are entitled to receive the distribution, unless the depositary determines that it is not feasible to make the distribution. If this occurs, the depositary, with our approval, may adopt another method for the distribution, including selling the property and distributing the net proceeds to the holders.
Liquidation preference
If a series of preferred stock underlying the depositary shares has a liquidation preference, in the event of our voluntary or involuntary liquidation, dissolution or winding up, holders of depositary shares will be entitled to receive the fraction of the liquidation preference accorded each share of the applicable series of preferred stock, as set forth in the applicable prospectus supplement.
Redemption
If a series of preferred stock underlying the depositary shares is subject to redemption, the depositary shares will be redeemed from the proceeds received by the depositary resulting from the redemption, in whole or in part, of the preferred stock held by the depositary. Whenever we redeem any preferred stock held by the depositary, the depositary will redeem, as of the same redemption date, the number of depositary shares representing the preferred stock so redeemed. The depositary will mail the notice of redemption to the record holders of the depositary receipts

promptly upon receiving the notice from us and not fewer than 20 or more than 60 days, unless otherwise provided in the applicable prospectus supplement, prior to the date fixed for redemption of the preferred stock.

Upon receipt of notice of any meeting at which the holders of preferred stock are entitled to vote, the depositary will mail the information contained in the notice of meeting to the record holders of the depositary receipts underlying the preferred stock. Each record holder of those depositary receipts on the record date will be entitled to instruct the depositary as to the exercise of the voting rights pertaining to the amount of preferred stock underlying that holder’s depositary shares. The record date for the depositary will be the same date as the record date for the preferred stock. The depositary will, to the extent practicable, vote the preferred stock underlying the depositary shares in accordance with these instructions. We will agree to take all action that may be deemed necessary by the depositary in order to enable the depositary to vote the preferred stock in accordance with these instructions. The depositary will not vote the preferred stock to the extent that it does not receive specific instructions from the holders of depositary receipts.
Withdrawal of preferred stock
Owners of depositary shares will be entitled to receive upon surrender of depositary receipts at the principal office of the depositary and payment of any unpaid amount due to the depositary, the number of whole shares of preferred stock underlying their depositary shares.
Partial shares of preferred stock will not be issued. Holders of preferred stock will not be entitled to deposit the shares under the deposit agreement or to receive depositary receipts evidencing depositary shares for the preferred stock.
Amendment and termination of the deposit agreement
The form of depositary receipt evidencing the depositary shares and any provision of the deposit agreement may be amended by agreement between the depositary and us. However, any amendment which materially and adversely alters the rights of the holders of depositary shares, other than fee changes, will not be effective unless the amendment has been approved by at least a majority of the outstanding depositary shares. The deposit agreement may be terminated by the depositary or us only if:
 
 	•	 	all outstanding depositary shares have been redeemed; or	
 
 	•	 	there has been a final distribution of the preferred stock in connection with our dissolution and such distribution has been made to all the holders of depositary shares.	
Charges of depositary
We will pay all transfer and other taxes and governmental charges arising solely from the existence of the depositary arrangement. We will also pay charges of the depositary in connection with:
 
 	•	 	the initial deposit of the preferred stock;	
 
 	•	 	the initial issuance of the depositary shares;	
 
 	•	 	any redemption of the preferred stock; and	
 
 	•	 	all withdrawals of preferred stock by owners of depositary shares.	
 
-12-

Table of Contents
Holders of depositary receipts will pay transfer, income and other taxes and governmental charges and other specified charges as provided in the deposit agreement for their accounts. If these charges have not been paid, the depositary may:
 
 	•	 	refuse to transfer depositary shares;	
 
 	•	 	withhold dividends and distributions; and	
 
 	•	 	sell the depositary shares evidenced by the depositary receipt.	
Miscellaneous
The depositary will forward to the holders of depositary receipts all reports and communications we deliver to the depositary that we are required to furnish to the holders of the preferred stock. In addition, the depositary will make available for inspection by holders of depositary receipts at the principal office of the depositary, and at such other places as it may from time to time deem advisable, any reports and communications we deliver to the depositary as the holder of preferred stock.
Neither the depositary nor we will be liable if either the depositary or we are prevented or delayed by law or any circumstance beyond the control of either the depositary or us in performing our respective obligations under the deposit agreement. Our obligations and the depositary’s obligations will be limited to the performance in good faith of our or the depositary’s respective duties under the deposit agreement. Neither the depositary nor we will be obligated to prosecute or defend any legal proceeding in respect of any depositary shares or preferred stock unless satisfactory indemnity is furnished. The depositary and we may rely on:
 
 	•	 	written advice of counsel or accountants;	
 
 	•	 	information provided by holders of depositary receipts or other persons believed in good faith to be competent to give such information; and	
 
 	•	 	documents believed to be genuine and to have been signed or presented by the proper party or parties.	
Resignation and removal of depositary
The depositary may resign at any time by delivering a notice to us. We may remove the depositary at any time. Any such resignation or removal will take effect upon the appointment of a successor depositary and its acceptance of such appointment. The successor depositary must be appointed within 60 days after delivery of the notice for resignation or removal. The successor depositary must be a bank and trust company having its principal office in the United States of America and having a combined capital and surplus of at least $50,000,000.
Federal income tax consequences
Owners of the depositary shares will be treated for U.S. federal income tax purposes as if they were owners of the preferred stock underlying the depositary shares. As a result, owners will be entitled to take into account for U.S. federal income tax purposes and deductions to which they would be entitled if they were holders of such preferred stock. No gain or loss will be recognized for U.S. federal income tax purposes upon the withdrawal of preferred stock in exchange for depositary shares. The tax basis of each share of preferred stock to an exchanging owner of depositary shares will, upon such exchange, be the same as the aggregate tax basis of the depositary shares exchanged. The holding period for preferred stock in the hands of an exchanging owner of depositary shares will include the period during which such person owned such depositary shares.

 DESCRIPTION OF THE DEBT SECURITIES
The debt securities may be either secured or unsecured and will either be our senior debt securities or our subordinated debt securities. The debt securities will be issued under one or more separate indentures between us and a trustee to be specified in an accompanying prospectus supplement. Senior debt securities will be issued under an Indenture, dated as of March 3, 2011, between us and The Bank of New York Mellon Trust Company, N.A., as trustee, referred to as the senior indenture. Subordinated debt securities will be issued under a subordinated indenture. Together, the senior indenture and the subordinated indenture are called indentures in this description. This prospectus, together with the applicable prospectus supplement, will describe the terms of a particular series of debt securities.
The following is a summary of selected provisions and definitions of the indentures and debt securities to which any prospectus supplement may relate. The summary of selected provisions of the indentures and the debt securities appearing below is not complete and is subject to, and qualified entirely by reference to, all of the provisions of the applicable indenture and certificates evidencing the applicable debt securities. For additional information, you should look at the applicable indenture and the certificate evidencing the applicable debt security that is filed as an exhibit to the registration statement that includes the prospectus. In this description of the debt securities, the words “we,” “us,” or “our” refer only to Juniper Networks, Inc. and not to any of our subsidiaries, unless we expressly state or the context otherwise requires.
The following description sets forth selected general terms and provisions of the applicable indenture and debt securities to which any prospectus supplement may relate. Other specific terms of the applicable indenture and debt securities will be described in the applicable prospectus supplement. If any particular terms of the indenture or debt securities described in a prospectus supplement differ from any of the terms described below, then the terms described below will be deemed to have been superseded by that prospectus supplement.
General
Debt securities may be issued in separate series without limitation as to aggregate principal amount. We may specify a maximum aggregate principal amount for the debt securities of any series.
We are not limited as to the amount of debt securities we may issue under the indentures. Unless otherwise provided in a prospectus supplement, a series of debt securities may be reopened to issue additional debt securities of such series.
The prospectus supplement relating to a particular series of debt securities will set forth:
 
 	•	 	whether the debt securities are senior or subordinated;	
 
 	•	 	the offering price;	
 
 	•	 	the title;	
 
 	•	 	any limit on the aggregate principal amount;	
 
 	•	 	the person who shall be entitled to receive interest, if other than the record holder on the record date;	
 
 	•	 	the date or dates the principal will be payable;	
 
 	•	 	the interest rate or rates, which may be fixed or variable, if any, the date from which interest will accrue, the interest payment dates and the regular record dates, or the method for calculating the dates and rates;	
 
 	•	 	the place where payments may be made;	
 
 	•	 	any mandatory or optional redemption provisions or sinking fund provisions and any applicable redemption or purchase prices associated with these provisions;	
 
-16-

Table of Contents

 	•	 	if issued other than in denominations of U.S. $1,000 or any multiple of U.S. $1,000, the denominations in which the debt securities shall be issuable;	
 
 	•	 	if applicable, the method for determining how the principal, premium, if any, or interest will be calculated by reference to an index or formula;	
 
 	•	 	if other than U.S. currency, the currency or currency units in which principal, premium, if any, or interest will be payable and whether we or a holder may elect payment to be made in a different currency;	
 
 	•	 	the portion of the principal amount that will be payable upon acceleration of maturity, if other than the entire principal amount;	
 
 	•	 	if the principal amount payable at stated maturity will not be determinable as of any date prior to stated maturity, the amount or method for determining the amount which will be deemed to be the principal amount;	
 
 	•	 	if applicable, whether the debt securities shall be subject to the defeasance provisions described below under “Satisfaction and discharge; defeasance” or such other defeasance provisions specified in the applicable prospectus supplement for the debt securities;	
 
 	•	 	any conversion or exchange provisions;	
 
 	•	 	whether the debt securities will be issuable in the form of a global security;	
 
 	•	 	any subordination provisions applicable to the subordinated debt securities if different from those described below under “Subordinated debt securities;”	
 
 	•	 	any paying agents, authenticating agents, security registrars or other agents for the debt securities, if other than the trustee;	
 
 	•	 	any provisions relating to any security provided for the debt securities, including any provisions regarding the circumstances under which collateral may be released or substituted;	
 
 	•	 	any deletions of, or changes or additions to, the events of default, acceleration provisions or covenants;	
 
 	•	 	any provisions relating to guaranties for the securities and any circumstances under which there may be additional obligors; and	
 
 	•	 	any other specific terms of such debt securities.	
Unless otherwise specified in the prospectus supplement, the debt securities will be registered debt securities. Debt securities may be sold at a substantial discount below their stated principal amount, bearing no interest or interest at a rate which at time of issuance is below market rates. The U.S. federal income tax considerations applicable to debt securities sold at a discount will be described in the applicable prospectus supplement.
Exchange and transfer
Debt securities may be transferred or exchanged at the office of the security registrar or at the office of any transfer agent designated by us.
We will not impose a service charge for any transfer or exchange, but we may require holders to pay any tax or other governmental charges associated with any transfer or exchange.
In the event of any partial redemption of debt securities of any series, we will not be required to:
 
 	•	 	issue, register the transfer of, or exchange, any debt security of that series during a period beginning at the opening of business 15 days before the day of mailing of a notice of redemption and ending at the close of business on the day of the mailing; or	
 
-17-

Table of Contents

 	•	 	register the transfer of or exchange any debt security of that series selected for redemption, in whole or in part, except the unredeemed portion being redeemed in part.	
We will appoint the trustee as the initial security registrar. Any transfer agent, in addition to the security registrar initially designated by us, will be named in the prospectus supplement. We may designate additional transfer agents or change transfer agents or change the office of the transfer agent. However, we will be required to maintain a transfer agent in each place of payment for the debt securities of each series.
Global securities
The debt securities of any series may be represented, in whole or in part, by one or more global securities. Each global security will:
 
 	•	 	be registered in the name of a depositary, or its nominee, that we will identify in a prospectus supplement;	
 
 	•	 	be deposited with the depositary or nominee or custodian; and	
 
 	•	 	bear any required legends.	
No global security may be exchanged in whole or in part for debt securities registered in the name of any person other than the depositary or any nominee unless:
 
 	•	 	the depositary has notified us that it is unwilling or unable to continue as depositary or has ceased to be qualified to act as depositary;	
 
 	•	 	an event of default is continuing with respect to the debt securities of the applicable series; or	
 
 	•	 	any other circumstance described in a prospectus supplement has occurred permitting or requiring the issuance of any such security.	
As long as the depositary, or its nominee, is the registered owner of a global security, the depositary or nominee will be considered the sole owner and holder of the debt securities represented by the global security for all purposes under the indentures. Except in the above limited circumstances, owners of beneficial interests in a global security will not be:
 
 	•	 	entitled to have the debt securities registered in their names;	
 
 	•	 	entitled to physical delivery of certificated debt securities; or	
 
 	•	 	considered to be holders of those debt securities under the indenture.	
Payments on a global security will be made to the depositary or its nominee as the holder of the global security. Some jurisdictions have laws that require that certain purchasers of securities take physical delivery of such securities in definitive form. These laws may impair the ability to transfer beneficial interests in a global security.
Institutions that have accounts with the depositary or its nominee are referred to as “participants.” Ownership of beneficial interests in a global security will be limited to participants and to persons that may hold beneficial interests through participants. The depositary will credit, on its book-entry registration and transfer system, the respective principal amounts of debt securities represented by the global security to the accounts of its participants.
Ownership of beneficial interests in a global security will be shown on and effected through records maintained by the depositary, with respect to participants’ interests, or any participant, with respect to interests of persons held by participants on their behalf.
Payments, transfers and exchanges relating to beneficial interests in a global security will be subject to policies and procedures of the depositary. The depositary policies and procedures may change from time to time. Neither any trustee nor we will have any responsibility or liability for the depositary’s or any participant’s records with respect to beneficial interests in a global security.

Payment and paying agents
Unless otherwise indicated in a prospectus supplement, the provisions described in this paragraph will apply to the debt securities. Payment of interest on a debt security on any interest payment date will be made to the person in whose name the debt security is registered at the close of business on the regular record date. Payment on debt securities of a particular series will be payable at the office of a paying agent or paying agents designated by us. However, at our option, we may pay interest by mailing a check to the record holder. The trustee will be designated as our initial paying agent.
We may also name any other paying agents in a prospectus supplement. We may designate additional paying agents, change paying agents or change the office of any paying agent. However, we will be required to maintain a paying agent in each place of payment for the debt securities of a particular series.
All moneys paid by us to a paying agent for payment on any debt security that remain unclaimed for a period ending the earlier of:
 
 	•	 	10 business days prior to the date the money would be turned over to the applicable state; or	
 
 	•	 	at the end of two years after such payment was due,	
will be repaid to us thereafter. The holder may look only to us for such payment.
No protection in the event of a change of control
Unless otherwise indicated in a prospectus supplement with respect to a particular series of debt securities, the debt securities will not contain any provisions that may afford holders of the debt securities protection in the event we have a change in control or in the event of a highly leveraged transaction, whether or not such transaction results in a change in control.
Covenants
Unless otherwise indicated in a prospectus supplement with respect to a particular series of debt securities, the debt securities will not contain any financial or restrictive covenants.
Consolidation, merger and sale of assets
Unless we indicate otherwise in a prospectus supplement with respect to a particular series of debt securities, we may not consolidate with or merge into any other person (other than a subsidiary of us), in a transaction in which we are not the surviving corporation, or convey, transfer or lease our properties and assets substantially as an entirety to, any person (other than a subsidiary of us), unless:
 
 	•	 	the successor entity, if any, is a U.S. corporation, limited liability company, partnership, trust or other business entity;	
 
 	•	 	the successor entity assumes our obligations on the debt securities and under the indentures;	
 
 	•	 	immediately after giving effect to the transaction, no default or event of default shall have occurred and be continuing; and	
 
 	•	 	certain other conditions specified in the indenture are met.	
Events of default
Unless we indicate otherwise in a prospectus supplement, the following will be events of default for any series of debt securities under the indentures:
 
 	(1)	we fail to pay principal of or any premium on any debt security of that series when due;	
 
 	(2)	we fail to pay any interest on any debt security of that series for 30 days after it becomes due;	
 
-19-

Table of Contents

 	(3)	we fail to deposit any sinking fund payment when due;	
 
 	(4)	we fail to perform any other covenant in the indenture and such failure continues for 90 days after we are given the notice required in the indentures; and	
 
 	(5)	certain events involving our bankruptcy, insolvency or reorganization.	
Additional or different events of default applicable to a series of debt securities may be described in a prospectus supplement. An event of default of one series of debt securities is not necessarily an event of default for any other series of debt securities.
The trustee may withhold notice to the holders of any default, except defaults in the payment of principal, premium, if any, interest, any sinking fund installment on, or with respect to any conversion right of, the debt securities of such series. However, the trustee must consider it to be in the interest of the holders of the debt securities of such series to withhold this notice.
Unless we indicate otherwise in a prospectus supplement, if an event of default, other than an event of default described in clause (5) above, shall occur and be continuing with respect to any series of debt securities, either the trustee or the holders of at least 25 percent in aggregate principal amount of the outstanding securities of that series may declare the principal amount and premium, if any, of the debt securities of that series, or if any debt securities of that series are original issue discount securities, such other amount as may be specified in the applicable prospectus supplement, in each case together with accrued and unpaid interest, if any, thereon, to be due and payable immediately.
Unless we indicate otherwise in a prospectus supplement, if an event of default described in clause (5) above shall occur, the principal amount and premium, if any, of all the debt securities of that series, or if any debt securities of that series are original issue discount securities, such other amount as may be specified in the applicable prospectus supplement, in each case together with accrued and unpaid interest, if any, thereon, will automatically become immediately due and payable. Any payment by us on the subordinated debt securities following any such acceleration will be subject to the subordination provisions described below under “Subordinated debt securities.”
Notwithstanding the foregoing, each indenture will provide that we may, at our option, elect that the sole remedy for an event of default relating to our failure to comply with our obligations described under the section entitled “Reports” below or our failure to comply with the requirements of Section 314(a)(1) of the Trust Indenture Act will for the first 180 days after the occurrence of such an event of default consist exclusively of the right to receive additional interest on the relevant series of debt securities at an annual rate equal to (i) 0.25% of the principal amount of such series of debt securities for the first 90 days after the occurrence of such event of default and (ii) 0.50% of the principal amount of such series of debt securities from the 91 st day to, and including, the 180 th day after the occurrence of such event of default, which we call “additional interest.” If we so elect, the additional interest will accrue on all outstanding debt securities from and including the date on which such event of default first occurs until such violation is cured or waived and shall be payable on each relevant interest payment date to holders of record on the regular record date immediately preceding the interest payment date. On the 181 st day after such event of default (if such violation is not cured or waived prior to such 181 st day), the debt securities will be subject to acceleration as provided above. In the event we do not elect to pay additional interest upon any such event of default in accordance with this paragraph, the debt securities will be subject to acceleration as provided above.
In order to elect to pay the additional interest as the sole remedy during the first 180 days after the occurrence of any event of default relating to the failure to comply with the reporting obligations in accordance with the preceding paragraph, we must notify all holders of debt securities and the trustee and paying agent of such election prior to the close of business on the first business day following the date on which such event of default occurs. Upon our failure to timely give such notice or pay the additional interest, the debt securities will be immediately subject to acceleration as provided above.
 
-20-

Table of Contents
After acceleration, the holders of a majority in aggregate principal amount of the outstanding securities of that series may, under certain circumstances, rescind and annul such acceleration if all events of default, other than the non-payment of accelerated principal, or other specified amounts or interest, have been cured or waived.
Other than the duty to act with the required care during an event of default, the trustee will not be obligated to exercise any of its rights or powers at the request of the holders unless the holders shall have offered to the trustee indemnity satisfactory to the trustee. Generally, the holders of a majority in aggregate principal amount of the outstanding debt securities of any series will 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.
A holder of debt securities of any series will not have any right to institute any proceeding under the indentures, or for the appointment of a receiver or a trustee, or for any other remedy under the indentures, unless:
 
 	(1)	the holder has previously given to the trustee written notice of a continuing event of default with respect to the debt securities of that series;	
 
 	(2)	the holders of at least 25 percent in aggregate principal amount of the outstanding debt securities of that series have made a written request and have offered reasonable indemnity to the trustee to institute the proceeding; and	
 
 	(3)	the trustee has failed to institute the proceeding and has not received direction inconsistent with the original request from the holders of a majority in aggregate principal amount of the outstanding debt securities of that series within 60 days after the original request.	
Holders may, however, sue to enforce the payment of principal, premium or interest on any debt security on or after the due date or to enforce the right, if any, to convert any debt security (if the debt security is convertible) without following the procedures listed in (1) through (3) above.
We will furnish the trustee an annual statement from our officers as to whether or not we are in default in the performance of the conditions and covenants under the indenture and, if so, specifying all known defaults.
Modification and waiver
Unless we indicate otherwise in a prospectus supplement, the applicable trustee and we may make modifications and amendments to an indenture with the consent of the holders of a majority in aggregate principal amount of the outstanding securities of each series affected by the modification or amendment.
We may also make modifications and amendments to the indentures for the benefit of holders without their consent, for certain purposes including, but not limited to:
 
 	•	 	providing for our successor to assume the covenants under the indenture;	
 
 	•	 	adding covenants or events of default;	
 
 	•	 	making certain changes to facilitate the issuance of the securities;	
 
 	•	 	securing the securities;	
 
 	•	 	providing for a successor trustee or additional trustees;	
 
 	•	 	conforming the indenture to the description of the debt securities set forth in this prospectus or the accompanying prospectus;	
 
 	•	 	curing any ambiguities or inconsistencies;	
 
 	•	 	providing for guaranties of, or additional obligors on, the securities;	
 
 	•	 	permitting or facilitating the defeasance and discharge of the securities; and	
 
 	•	 	other changes specified in the indenture.	
 
-21-

Table of Contents
However, neither the trustee nor we may make any modification or amendment without the consent of the holder of each outstanding security of that series affected by the modification or amendment if such modification or amendment would:
 
 	•	 	change the stated maturity of any debt security;	
 
 	•	 	reduce the principal, premium, if any, or interest on any debt security or any amount payable upon redemption or repurchase, whether at our option or the option of any holder, or reduce the amount of any sinking fund payments;	
 
 	•	 	reduce the principal of an original issue discount security or any other debt security payable on acceleration of maturity;	
 
 	•	 	change the place of payment or the currency in which any debt security is payable;	
 
 	•	 	impair the right to enforce any payment after the stated maturity or redemption date;	
 
 	•	 	if subordinated debt securities, modify the subordination provisions in a materially adverse manner to the holders;	
 
 	•	 	adversely affect the right to convert any debt security if the debt security is a convertible debt security; or	
 
 	•	 	change the provisions in the indenture that relate to modifying or amending the indenture.	
Satisfaction and discharge; defeasance
We may be discharged from our obligations on the debt securities, subject to limited exceptions, of any series that have matured or will mature or be redeemed within one year if we deposit enough money with the trustee to pay all the principal, interest and any premium due to the stated maturity date or redemption date of the debt securities.
Each indenture contains a provision that permits us to elect either or both of the following:
 
 	•	 	we may elect to be discharged from all of our obligations, subject to limited exceptions, with respect to any series of debt securities then outstanding. If we make this election, the holders of the debt securities of the series will not be entitled to the benefits of the indenture, except for the rights of holders to receive payments on debt securities or the registration of transfer and exchange of debt securities and replacement of lost, stolen or mutilated debt securities.	
 
 	•	 	we may elect to be released from our obligations under some or all of any financial or restrictive covenants applicable to the series of debt securities to which the election relates and from the consequences of an event of default resulting from a breach of those covenants.	
To make either of the above elections, we must irrevocably deposit in trust with the trustee enough money to pay in full the principal, interest and premium on the debt securities. This amount may be made in cash and/or U.S. government obligations or, in the case of debt securities denominated in a currency other than U.S. dollars, cash in the currency in which such series of securities is denominated and/or foreign government obligations. As a condition to either of the above elections, for debt securities denominated in U.S. dollars we must deliver to the trustee an opinion of counsel that the holders of the debt securities will not recognize income, gain or loss for U.S. federal income tax purposes as a result of the action.
With respect to debt securities of any series that are denominated in a currency other than United States dollars, “foreign government obligations” means:
 
 	•	 	direct obligations of the government that issued or caused to be issued the currency in which such securities are denominated and for the payment of which obligations its full faith and credit is pledged, or, with respect to debt securities of any series which are denominated in Euros, direct obligations of certain members of the European Union for the payment of which obligations the full faith and credit of such members is pledged, which in each case are not callable or redeemable at the option of the issuer thereof; or

 	•	 	obligations of a person controlled or supervised by or acting as an agency or instrumentality of a government described in the bullet above the timely payment of which is unconditionally guaranteed as a full faith and credit obligation by such government, which are not callable or redeemable at the option of the issuer thereof.	
Reports
The indentures provide that any reports or documents that we file with the SEC pursuant to Section 13 or 15(d) of the Exchange Act will be filed with the trustee within 15 days after the same is filed with the SEC. Documents filed by us with the SEC via the EDGAR system will be deemed filed with the trustee as of the time such documents are filed with the SEC.
Notices
Notices to holders will be given by mail to the addresses of the holders in the security register.
Governing law
The indentures and the debt securities will be governed by, and construed under, the laws of the State of New York.
No personal liability of directors, officers, employees and stockholders
No incorporator, stockholder, employee, agent, officer, director or subsidiary of ours will have any liability for any obligations of ours, or because of the creation of any indebtedness under the debt securities, the indentures or supplemental indentures. The indentures provide that all such liability is expressly waived and released as a condition of, and as a consideration for, the execution of such indentures and the issuance of the debt securities.
Regarding the trustee
The indentures limit the right of the trustee, should it become our creditor, to obtain payment of claims or secure its claims.
The trustee will be permitted to engage in certain other transactions with us. However, if the trustee acquires any conflicting interest, and there is a default under the debt securities of any series for which it is trustee, the trustee must eliminate the conflict or resign.
Subordinated debt securities
The following provisions will be applicable with respect to each series of subordinated debt securities, unless otherwise stated in the prospectus supplement relating to that series of subordinated debt securities.
The indebtedness evidenced by the subordinated debt securities of any series is subordinated, to the extent provided in the subordinated indenture and the applicable prospectus supplement, to the prior payment in full, in cash or other payment satisfactory to the holders of senior debt, of all senior debt, including any senior debt securities.
Upon any distribution of our assets upon any dissolution, winding up, liquidation or reorganization, whether voluntary or involuntary, marshalling of assets, assignment for the benefit of creditors, or in bankruptcy, insolvency, receivership or other similar proceedings, payments on the subordinated debt securities will be subordinated in right of payment to the prior payment in full in cash or other payment satisfactory to holders of senior debt of all senior debt.
 
-23-

Table of Contents
In the event of any acceleration of the subordinated debt securities of any series because of an event of default with respect to the subordinated debt securities of that series, holders of any senior debt would be entitled to payment in full in cash or other payment satisfactory to holders of senior debt of all senior debt before the holders of subordinated debt securities are entitled to receive any payment or distribution.
In addition, the subordinated debt securities will be structurally subordinated to all indebtedness and other liabilities of our subsidiaries, including trade payables and lease obligations. This occurs because our right to receive any assets of our subsidiaries upon their liquidation or reorganization, and your right to participate in those assets, will be effectively subordinated to the claims of that subsidiary’s creditors, including trade creditors, except to the extent that we are recognized as a creditor of such subsidiary. If we are recognized as a creditor of that subsidiary, our claims would still be subordinate to any security interest in the assets of the subsidiary and any indebtedness of the subsidiary senior to us.
We are required to promptly notify holders of senior debt or their representatives under the subordinated indenture if payment of the subordinated debt securities is accelerated because of an event of default.
Under the subordinated indenture, we may also not make payment on the subordinated debt securities if:
 
 	•	 	a default in our obligations to pay principal, premium, if any, interest or other amounts on our senior debt occurs and the default continues beyond any applicable grace period, which we refer to as a payment default; or	
 
 	•	 	any other default occurs and is continuing with respect to designated senior debt that permits holders of designated senior debt to accelerate its maturity, which we refer to as a non-payment default, and the trustee receives a payment blockage notice from us or some other person permitted to give the notice under the subordinated indenture.	
We will resume payments on the subordinated debt securities:
 
 	•	 	in case of a payment default, when the default is cured or waived or ceases to exist, and	
 
 	•	 	in case of a nonpayment default, the earlier of when the default is cured or waived or ceases to exist or 179 days after the receipt of the payment blockage notice.	
No new payment blockage period may commence on the basis of a nonpayment default unless 365 days have elapsed from the effectiveness of the immediately prior payment blockage notice. No nonpayment default that existed or was continuing on the date of delivery of any payment blockage notice to the trustee shall be the basis for a subsequent payment blockage notice.
As a result of these subordination provisions, in the event of our bankruptcy, dissolution or reorganization, holders of senior debt may receive more, ratably, and holders of the subordinated debt securities may receive less, ratably, than our other creditors. The subordination provisions will not prevent the occurrence of any event of default under the subordinated indenture.
The subordination provisions will not apply to payments from money or government obligations held in trust by the trustee for the payment of principal, interest and premium, if any, on subordinated debt securities pursuant to the provisions described under the section entitled “Satisfaction and discharge; defeasance,” if the subordination provisions were not violated at the time the money or government obligations were deposited into trust.
If the trustee or any holder receives any payment that should not have been made to them in contravention of subordination provisions before all senior debt is paid in full in cash or other payment satisfactory to holders of senior debt, then such payment will be held in trust for the holders of senior debt.
Senior debt securities will constitute senior debt under the subordinated indenture.
Additional or different subordination provisions may be described in a prospectus supplement relating to a particular series of debt securities.

“Designated senior debt” means our obligations under any particular senior debt in which the instrument creating or evidencing the same or the assumption or guarantee thereof, or related agreements or documents to which we are a party, expressly provides that such indebtedness shall be designated senior debt for purposes of the subordinated indenture. The instrument, agreement or other document evidencing any designated senior debt may place limitations and conditions on the right of such senior debt to exercise the rights of designated senior debt.
“Indebtedness” means the following, whether absolute or contingent, secured or unsecured, due or to become due, outstanding on the date of the indenture for such series of securities or thereafter created, incurred or assumed:

 	•	 	renewals, extensions, modifications, replacements, restatements and refundings of, or any indebtedness or obligation issued in exchange for, any such indebtedness or obligation described in the above clauses of this definition.

However, senior debt shall not include:
 
 	•	 	any debt or obligation if its terms or the terms of the instrument under which or pursuant to which it is issued expressly provide that it shall not be senior in right of payment to the subordinated debt securities or expressly provide that such indebtedness is on the same basis or “junior” to the subordinated debt securities; or	
 
 	•	 	debt to any of our subsidiaries, a majority of the voting stock of which is owned, directly or indirectly, by us.	
“Subsidiary” means a corporation more than 50% of the outstanding voting stock of which is owned, directly or indirectly, by us or by one or more or our other subsidiaries or by a combination of us and our other subsidiaries. For purposes of this definition, “voting stock” means stock or other similar interests which ordinarily has or have voting power for the election of directors, or persons performing similar functions, whether at all times or only so long as no senior class of stock or other interests has or have such voting power by reason of any contingency.

 DESCRIPTION OF THE PURCHASE CONTRACTS AND THE PURCHASE UNITS
We may issue purchase contracts, including contracts obligating holders to purchase from or sell to us, and obligating us to sell to or purchase from the holders, a specified number of shares of our common stock, preferred stock or depositary shares at a future date or dates, which we refer to in this prospectus as purchase contracts. The price per share of common stock, preferred stock or depositary shares and the number of shares of shares of each may be fixed at the time the purchase contracts are issued or may be determined by reference to a specific formula set forth in the purchase contracts. The purchase contracts may be issued separately or as part of units, often known as purchase units, consisting of one or more purchase contracts or beneficial interests in:
 
 	•	 	debt securities;	
 
 	•	 	debt obligations of third parties, including U.S. treasury securities; or	
 
 	•	 	any other securities described in the applicable prospectus supplement or any combination of the foregoing, securing the holders’ obligations to purchase the common stock, preferred stock or depositary shares under the purchase contracts.	
The purchase contracts may require us to make periodic payments to the holders of the purchase units or vice versa, and these payments may be unsecured or prefunded on some basis. The purchase contracts may require holders to secure their obligations under those contracts in a specified manner, including pledging their interest in another purchase contract.
The applicable prospectus supplement will describe the terms of the purchase contracts and purchase units, including, if applicable, collateral or depositary arrangements.

 PLAN OF DISTRIBUTION
We may sell the securities offered through this prospectus (1) to or through underwriters or dealers, (2) directly to purchasers, including our affiliates, (3) through agents, or (4) through a combination of any these methods. The securities may be distributed at a fixed price or prices, which may be changed, market prices prevailing at the time of sale, prices related to the prevailing market prices, or negotiated prices. The prospectus supplement will include the following information:
 
 	•	 	the terms of the offering;	
 
 	•	 	the names of any underwriters or agents;	
 
 	•	 	the name or names of any managing underwriter or underwriters;	
 
 	•	 	the purchase price of the securities;	
 
 	•	 	the net proceeds from the sale of the securities;	
 
 	•	 	any delayed delivery arrangements;	
 
 	•	 	any underwriting discounts, commissions and other items constituting underwriters’ compensation;	
 
 	•	 	any initial public offering price;	
 
 	•	 	any discounts or concessions allowed or reallowed or paid to dealers; and	
 
 	•	 	any commissions paid to agents.	
Sale through underwriters or dealers
If underwriters are used in the sale, the underwriters will acquire the securities for their own account, including through underwriting, purchase, security lending or repurchase agreements with us. The underwriters may resell the securities from time to time in one or more transactions, including negotiated transactions. Underwriters may sell the securities in order to facilitate transactions in any of our other securities (described in this prospectus or otherwise), including other public or private transactions and short sales. Underwriters may offer securities to the public either through underwriting syndicates represented by one or more managing underwriters or directly by one or more firms acting as underwriters. Unless otherwise indicated in the prospectus supplement, the obligations of the underwriters to purchase the securities will be subject to certain conditions, and the underwriters will be obligated to purchase all the offered securities if they purchase any of them. The underwriters may change from time to time any initial public offering price and any discounts or concessions allowed or reallowed or paid to dealers. The prospectus supplement will include the names of the principal underwriters the respective amount of securities underwritten, the nature of the obligation of the underwriters to take the securities and the nature of any material relationship between an underwriter and us.
If dealers are used in the sale of securities offered through this prospectus, we will sell the securities to them as principals. They may then resell those securities to the public at varying prices determined by the dealers at the time of resale. The prospectus supplement will include the names of the dealers and the terms of the transaction.
Direct sales and sales through agents
We may sell the securities offered through this prospectus directly. In this case, no underwriters or agents would be involved. Such securities may also be sold through agents designated from time to time. The prospectus supplement will name any agent involved in the offer or sale of the offered securities and will describe any commissions payable to the agent by us. Unless otherwise indicated in the prospectus supplement, any agent will agree to use its reasonable best efforts to solicit purchases for the period of its appointment.
We may sell the securities directly to institutional investors or others who may be deemed to be underwriters within the meaning of the Securities Act with respect to any sale of those securities. The terms of any such sales will be described in the prospectus supplement.

Table of Contents
Delayed delivery contracts
If the prospectus supplement indicates, we may authorize agents, underwriters or dealers to solicit offers from certain types of institutions to purchase securities at the public offering price under delayed delivery contracts. These contracts would provide for payment and delivery on a specified date in the future. The contracts would be subject only to those conditions described in the prospectus supplement. The applicable prospectus supplement will describe the commission payable for solicitation of those contracts.
Market making, stabilization and other transactions
Unless the applicable prospectus supplement states otherwise, each series of offered securities will be a new issue and will have no established trading market. We may elect to list any series of offered securities on an exchange. Any underwriters that we use in the sale of offered securities may make a market in such securities, but may discontinue such market making at any time without notice. Therefore, we cannot assure you that the securities will have a liquid trading market.
Any underwriter may also engage in stabilizing transactions, syndicate covering transactions and penalty bids in accordance with Rule 104 under the Securities Exchange Act of 1934, as amended. Stabilizing transactions involve bids to purchase the underlying security in the open market for the purpose of pegging, fixing or maintaining the price of the securities. Syndicate covering transactions involve purchases of the securities in the open market after the distribution has been completed in order to cover syndicate short positions.
Penalty bids permit the underwriters to reclaim a selling concession from a syndicate member when the securities originally sold by the syndicate member are purchased in a syndicate covering transaction to cover syndicate short positions. Stabilizing transactions, syndicate covering transactions and penalty bids may cause the price of the securities to be higher than it would be in the absence of the transactions. The underwriters may, if they commence these transactions, discontinue them at any time.
Derivative transactions and hedging
We, the underwriters or other agents may engage in derivative transactions involving the securities. These derivatives may consist of short sale transactions and other hedging activities. The underwriters or agents may acquire a long or short position in the securities, hold or resell securities acquired and purchase options or futures on the securities and other derivative instruments with returns linked to or related to changes in the price of the securities. In order to facilitate these derivative transactions, we may enter into security lending or repurchase agreements with the underwriters or agents. The underwriters or agents may effect the derivative transactions through sales of the securities to the public, including short sales, or by lending the securities in order to facilitate short sale transactions by others. The underwriters or agents may also use the securities purchased or borrowed from us or others (or, in the case of derivatives, securities received from us in settlement of those derivatives) to directly or indirectly settle sales of the securities or close out any related open borrowings of the securities.
Electronic auctions
We may also make sales through the Internet or through other electronic means. Since we may from time to time elect to offer securities directly to the public, with or without the involvement of agents, underwriters or dealers, utilizing the Internet or other forms of electronic bidding or ordering systems for the pricing and allocation of such securities, you should pay particular attention to the description of that system we will provide in a prospectus supplement.
Such electronic system may allow bidders to directly participate, through electronic access to an auction site, by submitting conditional offers to buy that are subject to acceptance by us, and which may directly affect the price or other terms and conditions at which such securities are sold. These bidding or ordering systems may

Table of Contents
present to each bidder, on a so-called “real-time” basis, relevant information to assist in making a bid, such as the clearing spread at which the offering would be sold, based on the bids submitted, and whether a bidder’s individual bids would be accepted, prorated or rejected. For example, in the case of a debt security, the clearing spread could be indicated as a number of “basis points” above an index treasury note. Of course, many pricing methods can and may also be used.
Upon completion of such an electronic auction process, securities will be allocated based on prices bid, terms of bid or other factors. The final offering price at which securities would be sold and the allocation of securities among bidders would be based in whole or in part on the results of the Internet or other electronic bidding process or auction.
General information
Agents, underwriters, and dealers may be entitled, under agreements entered into with us, to indemnification by us against certain liabilities, including liabilities under the Securities Act.
