BUSINESS Overview PART 1 We provide a cloud-based marketing and sales software platform, which we refer to as our Software Platform, that enables businesses to deliver an inbound experience. An inbound marketing and sales experience attracts, engages and delights customers by being more relevant, more helpful, more personalized and less interruptive than traditional marketing and sales tactics. Our Software Platform features integrated applications to help businesses attract visitors to their websites, convert visitors into leads, close leads into customers and delight customers so that they become promoters of those businesses. These integrated applications include social media, search engine optimization, blogging, website content management, marketing automation, email, sales productivity, CRM, analytics, and reporting. People have transformed how they consume information, research products and services, make purchasing decisions and share their views and experiences. Today, customers are blocking out the tactics from the traditional marketing and sales playbook, such as cold calls, unsolicited emails and disruptive advertisements. Customers are taking more control of the purchasing process by using technology, including search engines and social media, to research products and services. To compete effectively, we believe businesses need to deliver an inbound experience by adopting new strategies and technologies to attract, engage and delight customers. We designed our all-in-one Software Platform from the ground up to enable businesses to provide an inbound experience to their prospects and customers. At the core of our Software Platform is a single inbound database for each business that captures its lead and customer activity throughout the customer lifecycle. Our Software Platform uses our centralized inbound database to empower businesses to create more personalized interactions with leads and customers, such as personalized emails, personalized social media alerts, personalized websites and targeted alerts for sales people. We provide a comprehensive set of integrated applications on our Software Platform, which offers businesses ease of use, power and simplicity. We designed and built our Software Platform to serve a large number of customers of any size with demanding use cases. While our Software Platform can scale to the enterprise, we focus on selling to mid-market businesses, which we define as businesses that have between 10 and 2,000 employees. We believe we have significant competitive advantages attracting and serving this market segment. We efficiently reach these businesses at scale through our proven inbound go-to-market approach, freemium pricing strategy and thousands of marketing agency and sales partners, which we refer to as our Partners, worldwide. Our Software Platform is particularly suited to serving the needs of mid-market business-to-business, or B2B, companies. These mid- market businesses seek an integrated, easy to implement and easy to use solution to reach customers and compete with organizations that have larger marketing and sales budgets. As of December 31, 2017, we had 41,593 total customers of varying sizes in more than 90 countries, representing almost every industry. We have a leading brand in the cloud-based inbound marketing and sales software industry. Our brand recognition comes from our thought leadership, including our blogs, which average more than 4.5 million visits each month, and our commitment to innovation. Our founders, Brian Halligan and Dharmesh Shah, wrote the best-selling marketing book Inbound Marketing: Get Found Using Google, Social Media and Blogs. We also have one of the largest social media followings in our industry and our INBOUND conference is one of the largest inbound industry events, with over 21,000 registered attendees in 2017. We sell our Software Platform on a subscription basis. Our total revenue increased to $375.6 million in 2017, from $271.0 million in 2016, and from $181.9 million in 2015, representing year-over-year increases of 39% in 2017 and 49% in 2016. We had net losses of $39.7 million in 2017, $45.6 million in 2016, and $46.1 million in 2015. Industry Background The Traditional Business Playbook is Broken Traditionally, most businesses have followed the same marketing and sales playbook to generate leads, close sales and provide support to their customers; a playbook that uses the same interruptive and generic marketing tactics used for years. Today, however, customers are increasingly selecting their own communication channels and expecting personalized experiences. They are blocking out traditional marketing and sales tactics, such as cold calls, unsolicited emails and disruptive advertisements, and instead, they are using search engines and social media to research products and services before they contact a vendor. Customers are increasingly taking more control of the purchasing process and influencing the purchasing behavior of others. 2 Customers are blocking out traditional marketing and sales tactics . Customers are ignoring traditional marketing and sales tactics, often by using technology to block them out. For example: • • • • Hundreds of millions phone of numbers have been placed on the U.S. Do Not Call registry. People have unsubscribed from email marketing lists. Email services and spam filters are increasingly enabling customers to filter out and de-prioritize promotional messages. Online advertising has limited engagement. Customers are taking control of the purchasing process. Customers can now get the information they need on their own terms. Using search engines, social media and websites, customers can research vendors and actively seek recommendations from members of their social networks. As a result, customers no longer need to talk to a salesperson until they have completed most of their purchasing decision. This limits the amount of influence businesses can have on purchase decisions when using the traditional business playbook. Customers are influencing the purchasing behaviors of others. Customers are relying less on the promotional material from businesses and instead using online reviews and input from other purchasers to make their purchasing decision. Such social behavior is self-reinforcing: social buyers themselves are social sellers who influence others’ purchasing decisions. Businesses Need a New Playbook—The Inbound Experience Businesses need a more effective way to attract, engage and delight customers who have access to an abundance of information and an ability to block traditional marketing and sales tactics. To do this, businesses need to deliver an inbound experience, which enables them to be more helpful, more relevant and less interruptive to their customers. To deliver an inbound experience, businesses need to transform how they market, sell and serve customers. • • • Marketing : Businesses need to attract potential customers by maximizing search engine rankings, having an engaging social media presence, and creating and distributing useful and relevant content. Businesses need to personalize their customer interactions on websites, in social media and in emails to engage customers. Sales : Businesses need to build relationships with potential customers and become their trusted advisors. They must learn about and react to the signals being sent by customers through websites, social media and emails, to provide personalized and helpful responses. Service : Businesses need to delight their customers and inspire them to become vocal promoters by exceeding their expectations. Every customer has a stronger, more public voice today through blogs and social media, underscoring the importance of positive reviews and referrals in building a quality brand. Existing Applications are Not Adequate for an Integrated Inbound Experience Today, businesses often use a variety of point applications for their marketing and sales efforts, including advertising, marketing automation, content management, blogging, social media management, analytics, sales productivity and CRM. Most of these point applications were not designed to deliver an inbound experience. Typically, they do not provide a central view of all customer interactions across channels, are difficult and expensive to implement and use together, and make it hard to measure results. We believe that these existing point applications were not designed with the platform, architecture and functionality necessary to deliver a seamless integrated inbound experience. Not Designed for an Inbound Experience. Traditional marketing applications rely on advertising and cold calling for lead generation instead of inbound methods. These applications are not designed to personalize and optimize every interaction with customers on websites, in social media and by email across devices, and do not typically allow sales and service teams to see the signals their prospects are sending in real time. No Centralized Inbound Database of Customer Interactions. Businesses typically need to use one point application for website content management, a different point application for blogging, another point application for social media management, another point application for email and marketing automation, another point application for content personalization, another point application for analytics, another point application for sales management and CRM, and yet another point application to alert salespeople of key customer signals in real time. This disparate collection of point applications makes it difficult to get a 360- degree view of a customer’s interactions and use that data to provide a better customer experience and drive a more effective marketing and sales process. 3 Difficult and Expensive to Implement and Use. Using a collection of disparate point a pplications means a separate implementation process for each. Often businesses will need to use outside consultants or hire new employees with specific technical expertise to implement and use these different applications, resulting in significant addition al costs. This collection of disparate point applications also requires that businesses manage a variety of different log-ins and user interfaces, as well as get support from different vendors, often just to do something the business sees as one process, s uch as running a marketing campaign. While ease of implementation and use are important for businesses of all sizes, they are critical for mid-market businesses. Hard to Measure Results. Because all the customer touchpoints through the marketing, sales and service processes are typically stored in different disconnected point applications, it is very difficult to get a 360-degree view of a customer’s interactions and measure the effectiveness of marketing and sales programs. Businesses will often purchase yet another application to try to measure results across their multiple applications, adding even more expense and complexity to an already complex collection of different point applications. Market Opportunity We believe there is a large market opportunity created by the fundamental transformation in marketing and sales. Businesses of nearly all sizes and in nearly all industries can benefit from delivering an inbound experience to attract, engage and delight their customers. We focus on selling our Software Platform to mid- market businesses. As of December 31, 2017, we had 41,593 total customers, and our total average subscription revenue per customer for the year ended December 31, 2017 was $10,180. We believe our Software Platform addresses several segments of existing marketing, sales and services software and that spending in each of these segments will increasingly shift to platforms that enable an inbound experience. Advantages of Our Solution We provide our Software Platform that helps businesses attract, engage and delight customers throughout the customer lifecycle. Our Software Platform features a central inbound database of lead and customer interactions and integrated applications to help businesses attract visitors to their websites, convert visitors into leads, close leads into customers and delight customers so they become promoters of those businesses. Designed for an Inbound Experience. Our Software Platform was architected from the ground up to enable businesses to transform their marketing and sales playbook to meet the demands of today’s customers. Our Software Platform includes integrated applications to help businesses efficiently attract more customers through search engine optimization, social media, blogging and other useful content. In addition, our Software Platform is designed to help businesses personalize and optimize interactions with their customers through websites, landing pages, social media and emails, and across devices. Ease of Use of All-In-One Platform. We provide a set of integrated applications on a common platform, which offers businesses ease of use and simplicity. Our Software Platform has one login, one user interface, one inbound database and one number to call for support: 888-HUBSPOT. Our Software Platform is designed to be used by people without technical training, does not require an expert or technical system administrator and was built to make it easy to get started. Because of its ease of use and integration, our Software Platform enables businesses to focus on attracting, engaging and delighting customers, instead of spending time and money coordinating their marketing and sales efforts across multiple point applications. Power of All-In-One Platform. At the core of our Software Platform is a single inbound database for each business that captures its lead and customer activity throughout the customer lifecycle. For example, our Software Platform creates a unified timeline incorporating all the interactions with a particular person. If a business’s customer visits its website, comments on its blog, opens an email it sent, interacts with the business on Twitter, watches one of its videos, fills out a form, or is marked as a sales opportunity by its salesperson, all of that activity is centrally managed and presented on the timeline for that contact and is available for use across our applications. Our Software Platform also makes it easy to use the customer data to empower more personalized interactions with the customer, such as personalized social media alerts, personalized content on a business’s website, personalized emails and targeted alerts to its sales people. Clear ROI for Customers. Our Software Platform delivers proven and measurable results for our customers. Our customers often experience significant increases in the volume of traffic to their websites, the volume of inbound leads and the rate of converting leads into customers. Scalability. Our Software Platform was designed and built to serve a large number of customers of any size and with demanding use cases. Our Software Platform currently processes billions of data points each week, and we use leading global cloud infrastructure providers and our own automation technology to dynamically allocate capacity to handle processing workloads of all sizes. We have built our Software Platform on modern technologies, including HBase and Hadoop, which we believe are more scalable than traditional database technologies. Our scalability gives us flexibility for future growth and enables us to service a large variety of businesses of different sizes across different industries. 4 Extendable and Open Architecture. Our Software Platform features a variety of open APIs that allows easy integration of our platform with other applications. We enable our customers to co nnect our platform to their other applications, including CRM and ecommerce applications. By connecting third-party applications, our customers can leverage our centralized inbound database to perform additional functions and analysis. Our Competitive Strengths We believe that our market leadership position is based on the following key strengths: Leading Platform. We have designed and built a world-class, Software Platform. We believe our customers choose our Software Platform over others because of its powerful, integrated and easy to use applications. Independent customer reviews and ratings of our Software Platform compared to other applications show that we have high customer satisfaction. Market Leadership and Strong Brand. We are a recognized thought leader in the cloud-based inbound marketing and sales software industry with a leading brand. Our founders, Brian Halligan and Dharmesh Shah, wrote the best-selling marketing book Inbound Marketing: Get Found Using Google, Social Media and Blogs. More than 90,000 copies have been sold and it is available in nine languages. There are more than 145 self-organized HubSpot user groups. We also have over 2.5 million followers and fans among Twitter, Facebook, LinkedIn and Instagram as of December 31, 2017, including over 145,000 members of LinkedIn who belong to our inbound marketers group. Our INBOUND conference is one of the largest inbound industry conference events with attendance increasing from 1,100 in 2011 to over 21,000 registered attendees in 2017. We believe that it is inherently difficult to replicate the number of websites that link to us, the volume of useful content we have published, our large social media following, the breadth of our search engine rankings and our overall brand strength because these assets cannot be easily purchased or built. Large and Growing Partner Program. Thousands of agencies partner with us for the value of our Software Platform to their business including being able to offer new inbound marketing and sales services to their clients which can grow their revenue per customer, attract new customers and increase the portion of their clients on a retainer relationship. We believe that the wide adoption of our Software Platform in the agency industry is evidence that we are becoming an industry standard. Partners and customers referred to us by our Partners represented approximately 36 % of our total customers as of December 31, 2017, and approximately 40% of our revenue for the year ended December 31, 2017. These Partners help us to promote the vision of the inbound experience, efficiently reach new mid-market businesses at scale and provide our mutual customers with more diverse and higher-touch services. Mid-Market Focus. We believe we have significant competitive advantages reaching mid-market businesses and efficiently reach this market at scale as a result of our proven inbound go-to-market approach and our Partner channel. In 2017, over 86% of the new leads we generated and over 89% of our new customers were from inbound marketing and did not have any advertising costs associated with them. We believe our large inbound marketing footprint, Partner program, and freemium pricing strategy provide competitive advantages in reaching mid-market businesses. Powerful Network Effects. We have built a large and growing ecosystem around our Software Platform and company. We have built what we believe is the largest engaged audience in our industry, which now comprises more than 7 million people between visitors to our blogs, Twitter followers, Facebook fans, LinkedIn connections. We have attracted thousands of Partners worldwide who promote our brand and extend our marketing and sales reach. Thousands of our customers integrate third-party applications with our Software Platform using our built-in connectors and third-party developer partners. We have trained and currently certified more than 130,000 marketers on inbound marketing. Our annual INBOUND conference attracted more than 21,000 registered attendees in 2017. We believe this ecosystem drives more businesses and professionals to embrace the inbound playbook. As our engaged audience grows, more agencies partner with us, more third-party developers integrate their applications with our Software Platform, and more professionals complete our certification programs, all of which drive more businesses to adopt our Software Platform. Our Growth Strategy The key elements to our growth strategy are: Grow Our U.S. Customer Base. The market for our Software Platform is large and underserved. Mid-market businesses are particularly underserved by existing point application vendors and often lack sufficient resources to implement complex solutions. Our all-in-one Software Platform allows mid-market businesses to efficiently adopt and execute an effective inbound marketing and sales strategy to help them expand and grow. We will continue to leverage our inbound go-to-market approach and our network of Partners to keep growing our domestic business. 5 Increase Revenue from Existing Customers. Wi th 41,593 total customers in more than 90 countries spanning many industries, we believe we have a significant opportunity to increase revenue from our existing customers. We plan to increase revenue from our existing customers by expanding their use of ou r Software Platform, selling to other parts of their organizations, cross-selling our sales products to existing marketing customers and vice versa through touchless or low touch in product purchases, and upselling additional offerings and features. Our sc alable pricing model allows us to capture more spend as our customers grow, increase the number of their customers and prospects managed on our Software Platform, and require additional functionality available from our higher price tiers and add-ons, provi ding us with a substantial opportunity to increase the lifetime value of our customer relationships. Keep Expanding Internationally. There is a significant opportunity for our Software Platform outside of the United States. As of December 31, 2017, approximately 39 % of our total customers were located outside of the United States and these customers generated approximately 33 % of our total revenue for the year ended December 31, 2017. We sell to those foreign customers from our U.S., European, and Asia Pacific based operations. We intend to grow our presence in international markets through additional investments in local sales, marketing and professional service capabilities, as well as by leveraging our Partner network. We opened our first international office in Dublin, Ireland focused on the European market in January 2013 and our second, third and fourth international offices focused on the Asia Pacific market in Sydney, Australia in August 2014, Singapore in October 2015, and Tokyo, Japan in July 2016. In July 2017, we opened a fifth international office in Berlin, Germany. We already have significant website traffic from regions outside the United States and we believe that markets outside the United States represent a significant growth opportunity. Continue to Innovate and Expand Our Software Platform. Mid-market businesses are increasingly realizing the value of having an integrated marketing, sales and service platform. We believe we are well positioned to capitalize on this opportunity by introducing new products and applications to extend the functionality of our Software Platform. For example, in 2017 we launched a new HubSpot Sales Professional product tier with enhanced features such as artificial intelligence, advanced automation, and custom reporting, which enables growing teams to sell smarter, not harder. In addition, we added significant functionality to our core marketing, sales and CRM products throughout the year. The additional functionality includes: Content Strategy, an integrated content and search engine optimization, or SEO, tool that helps marketers adapt to the way modern search works and get more traffic with less content; Campaign Reporting, a powerful new set of reports that helps customers tie even their broadest marketing campaigns directly to the metrics that matter most: traffic, leads, and revenue; Smart List Retargeting, which allows companies with our Ads add-on to sync HubSpot lists to audiences in Facebook. This feature is intended to allow companies to retarget, nurture, and convert users dynamically based on HubSpot data. We also introduced a native integration with a leading e-commerce partner. Selectively Pursue Acquisitions. We plan to selectively pursue acquisitions of complementary businesses, technologies and teams that would allow us to add new features and functionalities to our platform and accelerate the pace of our innovation. Our Products All-in-one Software Platform HubSpot’s Software Platform is a collection of integrated tools that gives businesses everything they need to attract, engage, close, and delight new customers in a unified suite of tools.

The majority of our services and support is offered over the phone and via web meeting technology rather than in-person, which is a more efficient business model for us and more cost-effective for our customers. Professional Services. We offer professional services to educate and train customers on how to leverage our software platform and inbound marketing methodology to transform how their business attracts, engages and delights customers. Depending on which product plan and professional services a customer buys, it either receives group training and education in online or in-person classes or one-on-one training and advice from one of our implementation specialists by phone and web meeting. Our professional services are also available to customers who need additional assistance on a one-time or ongoing basis for an additional fee. 10 Support. In addition to assistance provided by our online articles and customer discussion forums, we offer phone and email-based support staffed in the United States, Ireland, Australia, Singapore, and Germany, which is included in the cost of a subscription for our marketing product. We strive to maintain an exceptional quality of customer service. We continuously monitor key customer service metrics such as phone hold time, ticket response time and ticket resolution rates, and we monitor the customer satisfactio n of our customer support interactions. We believe our customer support is an important reason why businesses choose our Software Platform and recommend it to their colleagues. Our Total Customers As of December 31, 2017, we had 41,593 total customers in more than 90 countries, representing many industries. No single customer represented more than 1% of our revenue in 2017, 2016 or 2015. Our Technology We have 41,593 total customers that have chosen us as their marketing and/or sales platform, which we architected and built to be secure, highly distributed and highly scalable. Since our founding, we have embraced rapid, iterative product development lifecycles, cloud automation and open-source technologies, including big data platforms, to power marketing and sales programs and provide insights not previously possible or available. Our Software Platform is a multi-tenant, single code-based, globally available software-as-a-service delivered through web browsers or mobile applications. Our commitment to a highly available, reliable and scalable platform for businesses of all sizes is accomplished through the use of these technologies. Modern Database Architecture. We process billions of data points weekly across various channels, including social media, email, SEO and website visits, and continue to drive nearly real-time analytics across these channels. This is possible because we built our database from the ground up using distributed big data technologies such as HBase and Hadoop to both process and analyze the large amounts of data we collect in our inbound database. Using modern database technologies, we can provide actionable insights across disparate data-sets in a manner not easily achievable or cost effectively, at scale or efficiently, with traditional databases or platform architectures. Agility. Our infrastructure and development and software release processes allow us to update our platform for specific groups of customers or our entire customer base at any time. This means we can rapidly innovate and deliver new functionality frequently, without waiting for quarterly or annual release cycles. We typically deploy updates to our software platform hundreds of times a week, enabling us to gather immediate customer feedback and improve our product quickly and continuously. Cost leverage. Because our Software Platform was built on an almost exclusive footprint of open-source software and designed to operate in cloud-based data-centers, we have benefited from large-scale price reductions by these cloud computing service providers as they continue to innovate and compete for market share. As our processing volume continues to grow, we continue to receive larger volume discounts on a per-unit basis for costs such as cost for storage, bandwidth and computing capacity. We also believe that our extensive use, and contribution to, open-source software will provide additional leverage as we scale our Software Platform and infrastructure. Scalability. By leveraging leading cloud infrastructure providers along with our automated technology stack, we are able to scale workloads of varying sizes at any time. This allows us to handle customers of all sizes and demands without traditional operational limitations such as network bandwidth, computing cycles, or storage capacity as we can scale our platform on-demand. Reliability. Customer data is distributed and processed across multiple data centers within a region to provide redundancy. We built our Software Platform on a distributed computing architecture with no single points of failure and we operate across data-center boundaries daily. In addition to data-center level redundancy, this architecture supports multiple live copies of each data set along with snapshot capabilities for faster, point-in-time data recovery instead of traditional backup and restore methodologies. Security. We leverage industry standard network and perimeter defense technologies, DDoS protection systems (including web application firewalls) and enterprise grade DNS services across multiple vendors. Our data-center providers operate and certify to high industry compliance levels. Due to the broad footprint of our customer base, we regularly test and evaluate our platform with trusted third-party vendors to ensure the security and integrity of our services. Marketing and Sales We believe we are a global leader in implementing an inbound experience in marketing and sales. We believe that our marketing and sales model provides us with a competitive advantage, especially when targeting mid-market businesses, because we can attract and engage these businesses efficiently and at scale. 11 Inbound Marketing. Our marketing team focuses on inbound marketing and attract s an average of over 100,000 new leads per month through our industry- leading blog and other content, free tools, large social media following, high search engine rankings and personalized website and email content. In addition, we are generating leads for new and add-on product purchases through content and offers delivered through our Software Platform to existing customers. Inbound sources generated over 89 % of our new customers and over 86 % of new leads during 201 7 . We believe most companies of our siz e and scale typically have a far lower volume of lead generation with a much larger share of it coming from traditional advertising methods. Inbound Direct Sales. Our sales representatives are based in our offices in Cambridge, Massachusetts, Dublin, Ireland, Sydney, Australia, Singapore, Tokyo, Japan, and Berlin, Germany and use phone, email and web meetings to interact with prospects and customers. The vast majority of revenue generated by our sales representatives originates with inbound leads produced by our marketing efforts. In addition, through our recently launched freemium products and in- product cross-sell offerings, we are starting to close new business with little or no interaction by our sales representatives. Inbound Channel Sales. In addition to our direct sales team, we have sales representatives that manage relationships with our worldwide network of Partners who both use our platform for their own businesses and also, on a commissioned basis, refer customers to us. These Partners partner with us not only to leverage our software platform and educational resources, but also to build their own business by offering new services and shifting their revenue mix to include more retainer-based business with a recurring revenue stream. Employees and Culture Transforming the business world to embrace the inbound experience requires a truly remarkable team. From the very beginning, our company was founded on a fundamental belief in radical transparency, individual autonomy and enlightened empathy. To that end, we published our “Culture Code,” a document codifying how we went about building a business that employees, customers and Partners alike truly love. Our Culture Code slide deck has been viewed approximately 3.6 million times on LinkedIn’s SlideShare and has become an important element of our recruiting efforts. The seven core principles of our Culture Code are: • • • • • • • We commit maniacally to both our mission and metrics. Our mission is to make the world inbound and transform how organizations attract, engage and delight their customers. We look to the long-term and “Solve for the Customer”. We solve for the customer, company, team and self, in that order. We share openly and are remarkably transparent. We believe that power is gained by sharing knowledge, not hoarding it and we share nearly all business information with all of our employees no matter their title or position. We favor autonomy and take ownership. We trust and empower each employee to use good judgment, and believe that results should matter more than when or where they are produced and that influence should be independent of hierarchy. We believe our best perk is amazing people. We value people who are humble, effective and predisposed to action, adaptable to change, remarkable standouts and transparent with others and with themselves. We dare to be different and question the status quo. We believe that remarkable outcomes rarely result from modest risk, and we’d rather be failing frequently than never trying new things. We recognize that life is short. We encourage candor and criticism as it helps us grow, but remember life is short so always be caring and kind. We are passionate about creating an inclusive company culture where employees can do their best work. Our Culture Code shares our core values and beliefs, including HEART (Humility, Empathy, Adaptability, Remark-ability, and Transparency), an acronym we use to describe what we believe makes a great HubSpotter. By recruiting people with HEART, investing in their growth, and making culture a business priority, we've been named a great place to work globally in 2017. This past year, HubSpot was named a Best Place to Work by Glassdoor, one of Boston Business Journal's Best Places to Work 2017, and a Best Workplace for Millennials by Fortune. We were also honored in a number of categories by Comparably's workplace awards in 2017, including Best CEOs, Best Companies for Women, Best Companies for Diversity, and Best Overall Company Culture. But, at the end of the day, we do not just talk about culture, we measure it, just as we do the rest of our business. We survey employees on a quarterly basis, making sure that our founders and executives review all the feedback, respond, and make adjustments when necessary. As of December 31, 2017 we had 2,081 full-time employees. Of these employees, 1,504 are based in the United States, 410 are located in Ireland, 54 are located in Australia, 73 are located in Singapore, 16 are located in Japan and 24 are located in Germany. 12 Competition Our market is evolving, highly competitive and fragmented, and we expect competition to increase in the future. We believe the principal competitive factors in our market are: • • • • • • • • • vision for the market and product strategy and pace of innovation; inbound marketing focus and domain expertise; integrated all-in-one platform; breadth and depth of product functionality; ease of use; scalable, open architecture; time to value and total cost of ownership; integration with third-party applications and data sources; and name recognition and brand reputation. We believe we compete favorably with respect to all of these factors. We face intense competition from other software companies that develop marketing software and from marketing services companies that provide interactive marketing services. Our competitors offer various point applications that provide certain functions and features that we provide, including: • • • • cloud-based marketing automation providers; email marketing software vendors; sales force automation and CRM software vendors; and large-scale enterprise suites. In addition, instead of using our platform, some prospective customers may elect to combine disparate point applications, such as content management, marketing automation, analytics and social media management. We expect that new competitors, such as enterprise software vendors that have traditionally focused on enterprise resource planning or other applications supporting back office functions, will develop and introduce, or acquire, applications serving customer-facing and other front office functions. Intellectual Property Our ability to protect our intellectual property, including our technology, will be an important factor in the success and continued growth of our business. We protect our intellectual property through trade secrets law, copyrights, trademarks, patents, and contracts. Some of our technology relies upon third-party licensed intellectual property. In addition to the foregoing, we have established business procedures designed to maintain the confidentiality of our proprietary information, including the use of confidentiality agreements and assignment of inventions agreements with employees, independent contractors, consultants and companies with which we conduct business. Financial Information About Segments We operate as one operating segment. Operating segments are defined as components of an enterprise for which separate financial information is regularly evaluated by the chief operating decision makers or CODMs, which are our chief executive officer and chief operating officer, in deciding how to allocate resources and assess performance. The CODMs evaluate our financial information and resources and assess the performance of these resources on a consolidated basis. Since we operate in one operating segment, all required financial segment information can be found in the consolidated financial statements. See Footnote 8 within the consolidated financial statements for information by geographic area. Available Information Our Annual Report on Fo rm 10-K, Quarterly Reports on Form 10-Q, Current Reports on Form 8-K and amendments to reports filed pursuant to Sections 13(a) and 15(d) of the Securities Exchange Act of 1934, as amended, are made available free of charge on or through our website at www.hubspot.com as soon as reasonably practicable after such reports are filed with, or furnished to, the SEC. 13 The SEC also maintains a website, www.sec.gov, that contains reports and other information regarding issuers that file electronically with the SEC. The public may read and copy any files with the SEC Public Reference Room at 100 F Street, NE, Washington, DC 20549. The public may obtain information on the operation of the Public Reference Room by calling 1-800-SEC-0330. We are not, however, including t he information contained on our website, or information that may be accessed through links on our website, as part of, or incorporating such information by reference into, this Annual Report on Form 10-K. Item 1A. RISK FACTORS An investment in our common stock involves a high degree of risk. You should carefully consider the risks described below and the other information in this Annual Report on Form 10-K and in our other public filings before making an investment decision. Our business, prospects, financial condition, or operating results could be harmed by any of these risks, as well as other risks not currently known to us or that we currently consider immaterial. If any of such risks and uncertainties actually occurs, our business, financial condition or operating results could differ materially from the plans, projections and other forward-looking statements included in the section titled “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and elsewhere in this report and in our other public filings. The trading price of our common stock could decline due to any of these risks, and, as a result, you may lose all or part of your investment. Risks Related to Our Business and Strategy We have a history of losses and may not achieve profitability in the future. We generated net losses of $39.7 million in 2017, $45.6 million in 2016, and $46.1 million in 2015. As of December 31, 2017, we had an accumulated deficit of $286.1 million. We will need to generate and sustain increased revenue levels in future periods to become profitable, and, even if we do, we may not be able to maintain or increase our level of profitability. We intend to continue to expend significant funds to grow our marketing and sales operations, develop and enhance our inbound platform, scale our data center infrastructure and services capabilities and expand into new markets. Our efforts to grow our business may be more costly than we expect, and we may not be able to increase our revenue enough to offset our higher operating expenses. We may incur significant losses in the future for a number of reasons, including the other risks described in this Annual Report on Form 10-K, and unforeseen expenses, difficulties, complications and delays and other unknown events. If we are unable to achieve and sustain profitability, the market price of our common stock may significantly decrease. We are dependent upon customer renewals, the addition of new customers, increased revenue from existing customers and the continued growth of the market for an inbound platform. We derive, and expect to continue to derive, a substantial portion of our revenue from the sale of subscriptions to our inbound platform. The market for inbound marketing and sales products is still evolving, and competitive dynamics may cause pricing levels to change as the market matures and as existing and new market participants introduce new types of point applications and different approaches to enable businesses to address their respective needs. As a result, we may be forced to reduce the prices we charge for our platform and may be unable to renew existing customer agreements or enter into new customer agreements at the same prices and upon the same terms that we have historically. In addition, our growth strategy involves a scalable pricing model (including “freemium” versions of our products) intended provide us with an opportunity to increase the value of our customer relationships over time as we expand their use of our platform, sell to other parts of their organizations, cross-sell our sales products to existing marketing product customers and vice versa through touchless or low touch in product purchases, and upsell additional offerings and features. If our cross-selling efforts are unsuccessful or if our existing customers do not expand their use of our platform or adopt additional offerings and features, our operating results may suffer. Our subscription renewal rates may decrease, and any decrease could harm our future revenue and operating results. Our customers have no obligation to renew their subscriptions for our platform after the expiration of their subscription periods, substantially all of which are one year or less. In addition, our customers may seek to renew for lower subscription amounts or for shorter contract lengths. Also, customers may choose not to renew their subscriptions for a variety of reasons, including an inability or failure on the part of a customer to create blogging, social media and other content necessary to realize the benefits of our platform. Our renewal rates may decline or fluctuate as a result of a number of factors, including limited customer resources, pricing changes, adoption and utilization of our platform and add-on applications by our customers, adoption of our new products, customer satisfaction with our platform, the acquisition of our customers by other companies and deteriorating general economic conditions. If our customers do not renew their subscriptions for our platform or decrease the amount they spend with us, our revenue will decline and our business will suffer. 14 We face significant competition from both established and new companies offering marketing and sales software and other related applications, as well as internally developed software, which may harm our ability to add new customers, retain existing customers and grow our business. The marketing and sales software market is evolving, highly competitive and significantly fragmented. With the introduction of new technologies and the potential entry of new competitors into the market, we expect competition to persist and intensify in the future, which could harm our ability to increase sales, maintain or increase renewals and maintain our prices. We face intense competition from other software companies that develop marketing and sales software and from marketing services companies that provide interactive marketing services. Competition could significantly impede our ability to sell subscriptions to our inbound marketing and sales platform on terms favorable to us. Our current and potential competitors may develop and market new technologies that render our existing or future products less competitive, or obsolete. In addition, if these competitors develop products with similar or superior functionality to our platform, we may need to decrease the prices or accept less favorable terms for our platform subscriptions in order to remain competitive. If we are unable to maintain our pricing due to competitive pressures, our margins will be reduced and our operating results will be negatively affected. Our competitors include: • • • • cloud-based marketing automation providers; email marketing software vendors; sales force automation and CRM software vendors; and large-scale enterprise suites. In addition, instead of using our platform, some prospective customers may elect to combine disparate point applications, such as content management, marketing automation, CRM, analytics and social media management. We expect that new competitors, such as enterprise software vendors that have traditionally focused on enterprise resource planning or other applications supporting back office functions, will develop and introduce applications serving customer-facing and other front office functions. This development could have an adverse effect on our business, operating results and financial condition. In addition, sales force automation and CRM system vendors could acquire or develop applications that compete with our marketing software offerings. Some of these companies have acquired social media marketing and other marketing software providers to integrate with their broader offerings. Our current and potential competitors may have significantly more financial, technical, marketing and other resources than we have, be able to devote greater resources to the development, promotion, sale and support of their products and services, may have more extensive customer bases and broader customer relationships than we have, and may have longer operating histories and greater name recognition than we have. As a result, these competitors may respond faster to new technologies and undertake more extensive marketing campaigns for their products. In a few cases, these vendors may also be able to offer marketing and sales software at little or no additional cost by bundling it with their existing suite of applications. To the extent any of our competitors has existing relationships with potential customers for either marketing software or other applications, those customers may be unwilling to purchase our platform because of their existing relationships with our competitor. If we are unable to compete with such companies, the demand for our inbound platform could substantially decline. In addition, if one or more of our competitors were to merge or partner with another of our competitors, our ability to compete effectively could be adversely affected. Our competitors may also establish or strengthen cooperative relationships with our current or future strategic distribution and technology partners or other parties with whom we have relationships, thereby limiting our ability to promote and implement our platform. We may not be able to compete successfully against current or future competitors, and competitive pressures may harm our business, operating results and financial condition. We have experienced rapid growth and organizational change in recent periods and expect continued future growth. If we fail to manage our growth effectively, we may be unable to execute our business plan, maintain high levels of service or address competitive challenges adequately. Our head count and operations have grown substantially. For example, we had 2,081 full-time employees as of December 31, 2017, as compared with 1,597 as of December 31, 2016. We opened our first international office in Dublin, Ireland in January 2013, and additional international offices in Sydney, Australia in August 2014, in Singapore in October 2015, in Tokyo in July 2016 and in Berlin in July 2017. This growth has placed, and will continue to place, a significant strain on our management, administrative, operational and financial infrastructure. We anticipate further growth will be required to address increases in our product offerings and continued expansion. Our success will depend in part upon our ability to recruit, hire, train, manage and integrate a significant number of qualified managers, technical personnel and employees in specialized roles within our company, including in technology, sales and marketing. If our new employees perform poorly, or if we are unsuccessful in recruiting, hiring, training, managing and integrating these new employees, or retaining these or our existing employees, our business may suffer. 15 In addition, to manage the expected continued growt h of our head count, operations and geographic expansion, we will need to continue to improve our information technology infrastructure, operational, financial and management systems and procedures. Our anticipated additional head count and capital investm ents will increase our costs, which will make it more difficult for us to address any future revenue shortfalls by reducing expenses in the short term. If we fail to successfully manage our growth, we will be unable to successfully execute our business pla n, which could have a negative impact on our business, results of operations or financial condition. Failure to effectively develop and expand our marketing and sales capabilities could harm our ability to increase our customer base and achieve broader market acceptance of our platform. To increase total customers and achieve broader market acceptance of our inbound platform, we will need to expand our marketing and sales operations, including our sales force and third-party channel partners. We will continue to dedicate significant resources to inbound sales and marketing programs. The effectiveness of our inbound sales and marketing and third-party channel partners has varied over time and may vary in the future and depends on our ability to maintain and improve our inbound platform. All of these efforts will require us to invest significant financial and other resources. Our business will be seriously harmed if our efforts do not generate a correspondingly significant increase in revenue. We may not achieve anticipated revenue growth from expanding our sales force if we are unable to hire, develop and retain talented sales personnel, if our new sales personnel are unable to achieve desired productivity levels in a reasonable period of time or if our sales and marketing programs are not effective. The rate of growth of our business depends on the continued participation and level of service of our marketing agency and sales partners. We rely on our marketing agency and sales partners to provide certain services to our customers, as well as pursue sales of our inbound platform to customers. To the extent we do not attract new marketing agency and sales partners, or existing or new marketing agency and sales partners do not refer a growing number of customers to us, our revenue and operating results would be harmed. In addition, if our marketing agency and sales partners do not continue to provide services to our customers, we would be required to provide such services ourselves either by expanding our internal team or engaging other third-party providers, which would increase our operating costs. If we cannot maintain our company culture as we grow, we could lose the innovation, teamwork, passion and focus on execution that we believe contribute to our success and our business may be harmed. We believe that a critical component to our success has been our company culture, which is based on transparency and personal autonomy. We have invested substantial time and resources in building our team within this company culture. Any failure to preserve our culture could negatively affect our ability to retain and recruit personnel and to effectively focus on and pursue our corporate objectives. As we grow as and continue to develop the infrastructure of a public company, we may find it difficult to maintain these important aspects of our company culture. If we fail to maintain our company culture, our business may be adversely impacted. If we fail to maintain our inbound thought leadership position, our business may suffer. We believe that maintaining our thought leadership position in inbound marketing, sales and services is an important element in attracting new customers. We devote significant resources to develop and maintain our thought leadership position, with a focus on identifying and interpreting emerging trends in the inbound experience, shaping and guiding industry dialog and creating and sharing the best inbound practices. Our activities related to developing and maintaining our thought leadership may not yield increased revenue, and even if they do, any increased revenue may not offset the expenses we incurred in such effort. We rely upon the continued services of our management and employees with domain expertise with inbound marketing, sales and services, and the loss of any key employees in this area could harm our competitive position and reputation. If we fail to successfully grow and maintain our thought leadership position, we may not attract enough new customers or retain our existing customers, and our business could suffer. If we fail to further enhance our brand and maintain our existing strong brand awareness, our ability to expand our customer base will be impaired and our financial condition may suffer. We believe that our development of the HubSpot brand is critical to achieving widespread awareness of our existing and future inbound experience solutions, and, as a result, is important to attracting new customers and maintaining existing customers. In the past, our efforts to build our brand have involved significant expenses, and we believe that this investment has resulted in strong brand recognition in the B2B market. Successful promotion and maintenance of our brands will depend largely on the effectiveness of our marketing efforts and on our ability to provide a reliable and useful inbound platform at competitive prices. Brand promotion activities may not yield increased revenue, and even if they do, any increased revenue may not offset the expenses we incurred in building our brand. If we fail to successfully promote and maintain our brand, our business could suffer. 16 If we fail to adapt and respond effectively to rapidly changing technology, evolving industry standards and changing customer needs or requirements, our inbound platform may become less competitive. Our future success depends on our ability to adapt and innovate our inbound platform. To attract new customers and increase revenue from existing customers, we need to continue to enhance and improve our offerings to meet customer needs at prices that our customers are willing to pay. Such efforts will require adding new functionality and responding to technological advancements, which will increase our research and development costs. If we are unable to develop new applications that address our customers’ needs, or to enhance and improve our platform in a timely manner, we may not be able to maintain or increase market acceptance of our platform. Our ability to grow is also subject to the risk of future disruptive technologies. Access and use of our inbound platform is provided via the cloud, which, itself, was disruptive to the previous enterprise software model. If new technologies emerge that are able to deliver inbound marketing software and related applications at lower prices, more efficiently, more conveniently or more securely, such technologies could adversely affect our ability to compete. We rely on our management team and other key employees, and the loss of one or more key employees could harm our business. Our success and future growth depend upon the continued services of our management team, including our co-founders, Brian Halligan and Dharmesh Shah, and other key employees in the areas of research and development, marketing, sales, services and general and administrative functions. From time to time, there may be changes in our management team resulting from the hiring or departure of executives, which could disrupt our business. We also are dependent on the continued service of our existing software engineers and information technology personnel because of the complexity of our platform, technologies and infrastructure. We may terminate any employee’s employment at any time, with or without cause, and any employee may resign at any time, with or without cause. We do not have employment agreements with any of our key personnel. The loss of one or more of our key employees could harm our business. The failure to attract and retain additional qualified personnel could prevent us from executing our business strategy. To execute our business strategy, we must attract and retain highly qualified personnel. In particular, we compete with many other companies for software developers with high levels of experience in designing, developing and managing cloud-based software, as well as for skilled information technology, marketing, sales and operations professionals, and we may not be successful in attracting and retaining the professionals we need. Also, inbound sales, marketing and services domain experts are very important to our success and are difficult to replace. We have from time to time in the past experienced, and we expect to continue to experience in the future, difficulty in hiring and difficulty in retaining highly skilled employees with appropriate qualifications. In particular, we have experienced a competitive hiring environment in the Greater Boston area, where we are headquartered. Many of the companies with which we compete for experienced personnel have greater resources than we do. In addition, in making employment decisions, particularly in the software industry, job candidates often consider the value of the stock options or other equity incentives they are to receive in connection with their employment. If the price of our stock declines, or experiences significant volatility, our ability to attract or retain key employees will be adversely affected. If we fail to attract new personnel or fail to retain and motivate our current personnel, our growth prospects could be severely harmed. If we fail to offer high-quality customer support, our business and reputation may suffer. High-quality education, training and customer support are important for the successful marketing, sale and use of our inbound platform and for the renewal of existing customers. Providing this education, training and support requires that our personnel who manage our online training resource, HubSpot Academy, or provide customer support have specific inbound experience domain knowledge and expertise, making it more difficult for us to hire qualified personnel and to scale up our support operations. The importance of high-quality customer support will increase as we expand our business and pursue new customers. If we do not help our customers use multiple applications within our inbound platform and provide effective ongoing support, our ability to sell additional functionality and services to, or to retain, existing customers may suffer and our reputation with existing or potential customers may be harmed. We may not be able to scale our business quickly enough to meet our customers’ growing needs and if we are not able to grow efficiently, our operating results could be harmed. As usage of our inbound platform grows and as customers use our platform for additional inbound applications, such as sales and services, we will need to devote additional resources to improving our application architecture, integrating with third-party systems and maintaining infrastructure performance. In addition, we will need to appropriately scale our internal business systems and our services organization, including customer support and professional services, to serve our growing customer base, particularly as our customer demographics change over time. Any failure of or delay in these efforts could cause impaired system performance and reduced customer satisfaction. These issues could reduce the attractiveness of our inbound platform to customers, resulting in decreased sales to new customers, lower renewal rates by existing customers, the issuance of service credits, or requested refunds, which could impede our revenue growth and harm our reputation. Even if we are able to upgrade our systems and expand our 17 staff, any such expansion will be expensive and complex, requiring management’s time and attention. We could also face inefficiencies or operational fail ures as a result of our efforts to scale our infrastructure. Moreover, there are inherent risks associated with upgrading, improving and expanding our information technology systems. We cannot be sure that the expansion and improvements to our infrastructu re and systems will be fully or effectively implemented on a timely basis, if at all. These efforts may reduce revenue and our margins and adversely affect our financial results. Our ability to introduce new products and features is dependent on adequate research and development resources. If we do not adequately fund our research and development efforts, we may not be able to compete effectively and our business and operating results may be harmed. To remain competitive, we must continue to develop new product offerings, applications, features and enhancements to our existing inbound platform. Maintaining adequate research and development personnel and resources to meet the demands of the market is essential. If we are unable to develop our platform internally due to certain constraints, such as high employee turnover, lack of management ability or a lack of other research and development resources, we may miss market opportunities. Further, many of our competitors expend a considerably greater amount of funds on their research and development programs, and those that do not may be acquired by larger companies that would allocate greater resources to our competitors’ research and development programs. Our failure to maintain adequate research and development resources or to compete effectively with the research and development programs of our competitors could materially adversely affect our business. Changes in the sizes or types of businesses that purchase our platform or in the applications within our inbound platform purchased or used by our customers could negatively affect our operating results. Our strategy is to sell subscriptions to our inbound platform to mid-sized businesses, but we have sold and will continue to sell to organizations ranging from small businesses to enterprises. Our gross margins can vary depending on numerous factors related to the implementation and use of our inbound platform, including the sophistication and intensity of our customers’ use of our platform and the level of professional services and support required by a customer. Sales to enterprise customers may entail longer sales cycles and more significant selling efforts. Selling to small businesses may involve greater credit risk and uncertainty. If there are changes in the mix of businesses that purchase our platform or the mix of the product plans purchased by our customers, our gross margins could decrease and our operating results could be adversely affected. We have in the past completed acquisitions and may acquire or invest in other companies or technologies in the future, which could divert management’s attention, fail to meet our expectations, result in additional dilution to our stockholders, increase expenses, disrupt our operations or harm our operating results. We have in the past acquired, and we may in the future acquire or invest in, businesses, products or technologies that we believe could complement or expand our platform, enhance our technical capabilities or otherwise offer growth opportunities. We may not be able to fully realize the anticipated benefits of these or any future acquisitions. The pursuit of potential acquisitions may divert the attention of management and cause us to incur various expenses related to identifying, investigating and pursuing suitable acquisitions, whether or not they are consummated. There are inherent risks in integrating and managing acquisitions. If we acquire additional businesses, we may not be able to assimilate or integrate the acquired personnel, operations and technologies successfully or effectively manage the combined business following the acquisition and our management may be distracted from operating our business. We also may not achieve the anticipated benefits from the acquired business due to a number of factors, including: unanticipated costs or liabilities associated with the acquisition; incurrence of acquisition-related costs, which would be recognized as a current period expense; inability to generate sufficient revenue to offset acquisition or investment costs; the inability to maintain relationships with customers and partners of the acquired business; the difficulty of incorporating acquired technology and rights into our platform and of maintaining quality and security standards consistent with our brand; delays in customer purchases due to uncertainty related to any acquisition; the need to integrate or implement additional controls, procedures and policies; challenges caused by distance, language and cultural differences; harm to our existing business relationships with business partners and customers as a result of the acquisition; the potential loss of key employees; use of resources that are needed in other parts of our business and diversion of management and employee resources; the inability to recognize acquired deferred revenue in accordance with our revenue recognition policies; and use of substantial portions of our available cash or the incurrence of debt to consummate the acquisition. Acquisitions also increase the risk of unforeseen legal liability, including for potential violations of applicable law or industry rules and regulations, arising from prior or ongoing acts or omissions by the acquired businesses which are not discovered by due diligence during the acquisition process. Generally, if an acquired business fails to meet our expectations, our operating results, business and financial condition may suffer. Acquisitions could also result in dilutive issuances of equity securities or the incurrence of debt, which could adversely affect our business, results of operations or financial condition. 18 In addition, a significant portion of the purchase price of companies we acquire may be allocated to goodwill and other intangible assets, which must be assessed for impairment at least annual ly. If our acquisitions do not ultimately yield expected returns, we may be required to make charges to our operating results based on our impairment assessment process, which could harm our results of operations. Because our long-term growth strategy involves further expansion of our sales to customers outside the United States, our business will be susceptible to risks associated with international operations. A component of our growth strategy involves the further expansion of our operations and customer base internationally. We opened our first international office in Dublin, Ireland in January 2013 and we opened additional international offices in Sydney, Australia in August 2014, in Singapore in October 2015, in Tokyo in July 2016, and in Berlin in July 2017. These international offices focus primarily on sales, professional services and support. We also have a development team in Dublin, Ireland. Our current international operations and future initiatives will involve a variety of risks, including: • • • • • • • • • • • • difficulties in maintaining our company culture with a dispersed and distant workforce; more stringent regulations relating to data security and the unauthorized use of, or access to, commercial and personal information, particularly in the European Union; unexpected changes in regulatory requirements, taxes or trade laws; differing labor regulations, especially in the European Union, where labor laws are generally more advantageous to employees as compared to the United States, including deemed hourly wage and overtime regulations in these locations; challenges inherent in efficiently managing an increased number of employees over large geographic distances, including the need to implement appropriate systems, policies, benefits and compliance programs; difficulties in managing a business in new markets with diverse cultures, languages, customs, legal systems, alternative dispute systems and regulatory systems; currency exchange rate fluctuations and the resulting effect on our revenue and expenses, and the cost and risk of entering into hedging transactions if we chose to do so in the future; limitations on our ability to reinvest earnings from operations in one country to fund the capital needs of our operations in other countries; limited or insufficient intellectual property protection; political instability or terrorist activities; likelihood of potential or actual violations of domestic and international anticorruption laws, such as the U.S. Foreign Corrupt Practices Act and the U.K. Bribery Act, or of U.S. and international export control and sanctions regulations, which likelihood may increase with an increase of sales or operations in foreign jurisdictions and operations in certain industries; and adverse tax burdens and foreign exchange controls that could make it difficult to repatriate earnings and cash. Our limited experience in operating our business internationally increases the risk that any potential future expansion efforts that we may undertake will not be successful. If we invest substantial time and resources to expand our international operations and are unable to do so successfully and in a timely manner, our business and operating results will suffer. We continue to implement policies and procedures to facilitate our compliance with U.S. laws and regulations applicable to or arising from our international business. Inadequacies in our past or current compliance practices may increase the risk of inadvertent violations of such laws and regulations, which could lead to financial and other penalties that could damage our reputation and impose costs on us. Interruptions or delays in service from our third-party data center providers could impair our ability to deliver our platform to our customers, resulting in customer dissatisfaction, damage to our reputation, loss of customers, limited growth and reduction in revenue. We currently serve the majority of our platform functions from third-party data center hosting facilities operated by Amazon Web Services and located in northern Virginia. In addition, we serve ancillary functions for our customers from third-party data center hosting facilities operated by Rackspace located in Dallas, Texas, with a backup facility in Chicago, Illinois. Our operations depend, in part, on our third-party facility providers’ abilities to protect these facilities against damage or interruption from natural disasters, such as earthquakes and hurricanes, power or telecommunications failures, criminal acts and similar events. In the event that any of our third-party facilities arrangements is terminated, or if there is a lapse of service or damage to a facility, we could experience interruptions in our platform as well as delays and additional expenses in arranging new facilities and services. 19 Any damage to, or failure of , the systems of our third-party providers could result in interruptions to our platform. Despite precautions taken at our data centers, the occurrence of spikes in usage volume, a natural disaster, such as earthquakes or hurricane, an act of terrorism, va ndalism or sabotage, a decision to close a facility without adequate notice, or other unanticipated problems at a facility could result in lengthy interruptions in the availability of our on-demand software. Even with current and planned disaster recovery arrangements, our business could be harmed. Also, in the event of damage or interruption, our insurance policies may not adequately compensate us for any losses that we may incur. These factors in turn could further reduce our revenue, subject us to liabil ity and cause us to issue credits or cause customers to fail to renew their subscriptions, any of which could materially adversely affect our business. We are dependent on the continued availability of third-party data hosting and transmission services. A significant portion of our operating cost is from our third-party data hosting and transmission services. If the costs for such services increase due to vendor consolidation, regulation, contract renegotiation, or otherwise, we may not be able to increase the fees for our inbound platform or services to cover the changes. As a result, our operating results may be significantly worse than forecasted. If we do not or cannot maintain the compatibility of our inbound platform with third-party applications that our customers use in their businesses, our revenue will decline. A significant percentage of our customers choose to integrate our platform with certain capabilities provided by third-party application providers using application programming interfaces, or APIs, published by these providers. The functionality and popularity of our inbound platform depends, in part, on our ability to integrate our platform with third-party applications and platforms, including CRM, CMS, e-commerce, call center, analytics and social media sites that our customers use and from which they obtain data. Third-party providers of applications and APIs may change the features of their applications and platforms, restrict our access to their applications and platforms or alter the terms governing use of their applications and APIs and access to those applications and platforms in an adverse manner. Such changes could functionally limit or terminate our ability to use these third-party applications and platforms in conjunction with our platform, which could negatively impact our offerings and harm our business. If we fail to integrate our platform with new third-party applications and platforms that our customers use for marketing, sales or services purposes, we may not be able to offer the functionality that our customers need, which would negatively impact our ability to generate revenue and adversely impact our business. We rely on data provided by third parties, the loss of which could limit the functionality of our platform and disrupt our business. Select functionality of our inbound platform depends on our ability to deliver data, including search engine results and social media updates, provided by unaffiliated third parties, such as Facebook, Google, LinkedIn and Twitter. Some of this data is provided to us pursuant to third-party data sharing policies and terms of use, under data sharing agreements by third-party providers or by customer consent. In the future, any of these third parties could change its data sharing policies, including making them more restrictive, or alter its algorithms that determine the placement, display, and accessibility of search results and social media updates, any of which could result in the loss of, or significant impairment to, our ability to collect and provide useful data to our customers. These third parties could also interpret our, or our service providers’, data collection policies or practices as being inconsistent with their policies, which could result in the loss of our ability to collect this data for our customers. Any such changes could impair our ability to deliver data to our customers and could adversely impact select functionality of our platform, impairing the return on investment that our customers derive from using our solution, as well as adversely affecting our business and our ability to generate revenue. Privacy concerns and end users’ acceptance of Internet behavior tracking may limit the applicability, use and adoption of our inbound platform. Privacy concerns may cause end users to resist providing the personal data necessary to allow our customers to use our platform effectively. We have implemented various features intended to enable our customers to better protect end user privacy, but these measures may not alleviate all potential privacy concerns and threats. Even the perception of privacy concerns, whether or not valid, may inhibit market adoption of our platform, especially in certain industries that rely on sensitive personal information. Privacy advocacy groups and the technology and other industries are considering various new, additional or different self-regulatory standards that may place additional burdens on us. The costs of compliance with, and other burdens imposed by these groups’ policies and actions may limit the use and adoption of our inbound platform and reduce overall demand for it, or lead to significant fines, penalties or liabilities for any noncompliance or loss of any such action. 20 We are subject to governmental regulation and other legal obligations, p articularly related to privacy, data protection and information security, and our actual or perceived failure to comply with such obligations could harm our business. Compliance with such laws could also impair our efforts to maintain and expand our custom er base, and thereby decrease our revenue. Our handling of data is subject to a variety of laws and regulations, including regulation by various government agencies, including the U.S. Federal Trade Commission, or FTC, and various state, local and foreign agencies. We collect personally identifiable information and other data from our customers and leads. We also handle personally identifiable information about our customers’ customers. We use this information to provide services to our customers, to support, expand and improve our business. We may also share customers’ personally identifiable information with third parties as authorized by the customer or as described in our privacy policy. The U.S. federal and various state and foreign governments have adopted or proposed limitations on the collection, distribution, use and storage of personal information of individuals. In the United States, the FTC and many state attorneys general are applying federal and state consumer protection laws as imposing standards for the online collection, use and dissemination of data. However, these obligations may be interpreted and applied in a manner that is inconsistent from one jurisdiction to another and may conflict with other requirements or our practices. Any failure or perceived failure by us to comply with privacy or security laws, policies, legal obligations or industry standards or any security incident that results in the unauthorized release or transfer of personally identifiable information or other customer data may result in governmental enforcement actions, litigation, fines and penalties and/or adverse publicity, and could cause our customers to lose trust in us, which could have an adverse effect on our reputation and business. Laws and regulations concerning privacy, data protection and information security are evolving, and changes to such laws and regulations could require us to change features of our platform or restrict our customers’ ability to collect and use email addresses, page viewing data and personal information, which may reduce demand for our platform. Our failure to comply with federal, state and international data privacy laws and regulations could harm our ability to successfully operate our business and pursue our business goals. In addition, several foreign countries and governmental bodies, including the European Union and Canada, have regulations dealing with the collection and use of personal information obtained from their residents, which are often more restrictive than those in the United States. Laws and regulations in these jurisdictions apply broadly to the collection, use, storage, disclosure and security of personal information that identifies or may be used to identify an individual. Within the European Union, legislators have adopted the General Data Protection Regulation, or GDPR, effective May 2018 which may impose additional obligations and risk upon our business and which may increase substantially the penalties to which we could be subject in the event of any non-compliance. We may incur substantial expense in complying with the new obligations to be imposed by the GDPR and we may be required to make significant changes in our business operations, all of which may adversely affect our revenues and our business overall. We have in the past relied upon adherence to the U.S. Department of Commerce’s Safe Harbor Privacy Principles and compliance with the U.S.-EU and U.S.-Swiss Safe Harbor Frameworks as agreed to and set forth by the U.S. Department of Commerce, and the European Union and Switzerland, which established a means for legitimating the transfer of personal data by data controllers in the European Economic Area, or EEA, to the U.S. As a result of the October 6, 2015 European Union Court of Justice, or ECJ, opinion in Case C-362/14 (Schrems v. Data Protection Commissioner) regarding the adequacy of the U.S.-EU Safe Harbor Framework, the U.S. – EU Safe Harbor Framework is no longer deemed to be a valid method of compliance with requirements set forth in the Directive (and member states’ implementations thereof) regarding the transfer of personal data outside of the EEA. On May 23, 2016, the European Parliament adopted a resolution and on July 8, 2016 the European Member State representatives approved the final version of the EU-US Privacy Shield as a successor to the Safe Harbor framework. As of August 1, 2016, interested companies have been permitted to register for the program. We are currently certified to the EU-US Privacy Shield. There continue to be concerns about whether the EU-US Privacy Shield will face additional challenges. Until the remaining legal uncertainties regarding the future of the EU-US Privacy Shield are settled, we will continue to face uncertainty as to whether our efforts to comply with our obligations under European privacy laws will be sufficient. If we are investigated by a European data protection authority, we may face fines and other penalties. Any such investigation or charges by European data protection authorities could have a negative effect on our existing business and on our ability to attract and retain new customers. We may also experience hesitancy, reluctance, or refusal by European or multi-national customers to continue to use our services due to the potential risk exposure to such customers as a result of the ECJ ruling in Case C-362/14 and the current data protection obligations imposed on them by certain data protection authorities. Such customers may also view any alternative approaches to compliance as being too costly, too burdensome, too legally uncertain or otherwise objectionable and therefore decide not to do business with us. For example, some of our customers or potential customers in the EU may require their vendors to host all personal data within the EU and may decide to do business with one of our competitors who hosts personal data within the EU instead of doing business with us. 21 We and our customers are at risk of enforcement actions taken by certain EU data protection authorities until such point in time that we may be ab le to ensure that all transfers of personal data to us from the EEA are conducted in compliance with all applicable regulatory obligations, the guidance of data protection authorities, and evolving best practices. We may find it necessary to establish syst ems to maintain personal data originating from the EU in the EEA, which may involve substantial expense and may cause us to need to divert resources from other aspects of our business, all of which may adversely affect our business. In addition, if our privacy or data security measures fail to comply with current or future laws and regulations, we may be subject to claims, legal proceedings or other actions by individuals or governmental authorities based on privacy or data protection regulations and our commitments to customers or others, as well as negative publicity and a potential loss of business. Moreover, if future laws and regulations limit our subscribers’ ability to use and share personal information or our ability to store, process and share personal information, demand for our solutions could decrease, our costs could increase, and our business, results of operations and financial condition could be harmed. If our or our customers’ security measures are compromised or unauthorized access to data of our customers or their customers is otherwise obtained, our inbound platform may be perceived as not being secure, our customers may be harmed and may curtail or cease their use of our platform, our reputation may be damaged and we may incur significant liabilities. Our operations involve the storage and transmission of data of our customers and their customers, including personally identifiable information. Our storage is typically the sole source of record for portions of our customers’ businesses and end user data, such as initial contact information and online interactions. Security incidents could result in unauthorized access to, loss of or unauthorized disclosure of this information, litigation, indemnity obligations and other possible liabilities, as well as negative publicity, which could damage our reputation, impair our sales and harm our customers and our business. Cyber-attacks and other malicious Internet-based activity continue to increase generally, and cloud-based platform providers of marketing services have been targeted. If our security measures are compromised as a result of third-party action, employee or customer error, malfeasance, stolen or fraudulently obtained log-in credentials or otherwise, our reputation could be damaged, our business may be harmed and we could incur significant liability. If third parties with whom we work, such as vendors or developers, violate applicable laws or our security policies, such violations may also put our customers’ information at risk and could in turn have an adverse effect on our business. In addition, if the security measures of our customers are compromised, even without any actual compromise of our own systems, we may face negative publicity or reputational harm if our customers or anyone else incorrectly attributes the blame for such security breaches to us or our systems. We may be unable to anticipate or prevent techniques used to obtain unauthorized access or to sabotage systems because they change frequently and generally are not detected until after an incident has occurred. As we increase our customer base and our brand becomes more widely known and recognized, we may become more of a target for third parties seeking to compromise our security systems or gain unauthorized access to our customers’ data. Additionally, we provide extensive access to our database, which stores our customer data, to our development team to facilitate our rapid pace of product development. If such access or our own operations cause the loss, damage or destruction of our customers’ business data, their sales, lead generation, support and other business operations may be permanently harmed. As a result, our customers may bring claims against us for lost profits and other damages. Many governments have enacted laws requiring companies to notify individuals of data security incidents or unauthorized transfers involving certain types of personal data. In addition, some of our customers contractually require notification of any data security compromise. Security compromises experienced by our competitors, by our customers or by us may lead to public disclosures, which may lead to widespread negative publicity. Any security compromise in our industry, whether actual or perceived, could harm our reputation, erode customer confidence in the effectiveness of our security measures, negatively impact our ability to attract new customers, cause existing customers to elect not to renew their subscriptions or subject us to third-party lawsuits, regulatory fines or other action or liability, which could materially and adversely affect our business and operating results. There can be no assurance that any limitations of liability provisions in our contracts for a security breach would be enforceable or adequate or would otherwise protect us from any such liabilities or damages with respect to any particular claim. We also cannot be sure that our existing general liability insurance coverage and coverage for errors or omissions will continue to be available on acceptable terms or will be available in sufficient amounts to cover one or more large claims, or that the insurer will not deny coverage as to any future claim. The successful assertion of one or more large claims against us that exceed available insurance coverage, or the occurrence of changes in our insurance policies, including premium increases or the imposition of large deductible or co-insurance requirements, could have a material adverse effect on our business, financial condition and operating results. If our inbound platform fails due to defects or similar problems, and if we fail to correct any defect or other software problems, we could lose customers, become subject to service performance or warranty claims or incur significant costs. Our platform and its underlying infrastructure are inherently complex and may contain material defects or errors. We release modifications, updates, bug fixes and other changes to our software several times per day, without traditional human-performed quality control reviews for each release. We have from time to time found defects in our software and may discover additional defects 22 in the future. We may not be able to detect and correct defects or errors before customers begin to use our platform or its applications. Consequently, we or ou r customers may discover defects or errors after our platform has been implemented. These defects or errors could also cause inaccuracies in the data we collect and process for our customers, or even the loss, damage or inadvertent release of such confiden tial data. We implement bug fixes and upgrades as part of our regular system maintenance, which may lead to system downtime. Even if we are able to implement the bug fixes and upgrades in a timely manner, any history of defects or inaccuracies in the data we collect for our customers, or the loss, damage or inadvertent release of confidential data could cause our reputation to be harmed, and customers may elect not to purchase or renew their agreements with us and subject us to service performance credits, warranty claims or increased insurance costs. The costs associated with any material defects or errors in our platform or other performance problems may be substantial and could materially adversely affect our operating results. Risks Related to Intellectual Property Our business may suffer if it is alleged or determined that our technology infringes the intellectual property rights of others. The software industry is characterized by the existence of a large number of patents, copyrights, trademarks, trade secrets and other intellectual and proprietary rights. Companies in the software industry, including those in marketing software, are often required to defend against litigation claims based on allegations of infringement or other violations of intellectual property rights. Many of our competitors and other industry participants have been issued patents and/or have filed patent applications and may assert patent or other intellectual property rights within the industry. Moreover, in recent years, individuals and groups that are non-practicing entities, commonly referred to as “patent trolls,” have purchased patents and other intellectual property assets for the purpose of making claims of infringement in order to extract settlements. From time to time, we may receive threatening letters or notices or may be the subject of claims that our services and/or platform and underlying technology infringe or violate the intellectual property rights of others. Responding to such claims, regardless of their merit, can be time consuming, costly to defend in litigation, divert management’s attention and resources, damage our reputation and brand and cause us to incur significant expenses. Our technologies may not be able to withstand any third-party claims or rights against their use. Claims of intellectual property infringement might require us to redesign our application, delay releases, enter into costly settlement or license agreements or pay costly damage awards, or face a temporary or permanent injunction prohibiting us from marketing or selling our platform. If we cannot or do not license the infringed technology on reasonable terms or at all, or substitute similar technology from another source, our revenue and operating results could be adversely impacted. Additionally, our customers may not purchase our inbound platform if they are concerned that they may infringe third-party intellectual property rights. The occurrence of any of these events may have a material adverse effect on our business. In our subscription agreements with our customers, we generally do not agree to indemnify our customers against any losses or costs incurred in connection with claims by a third party alleging that a customer’s use of our services or platform infringes the intellectual property rights of the third party. There can be no assurance, however, that customers will not assert a common law indemnity claim or that any existing limitations of liability provisions in our contracts would be enforceable or adequate, or would otherwise protect us from any such liabilities or damages with respect to any particular claim. Our customers who are accused of intellectual property infringement may in the future seek indemnification from us under common law or other legal theories. If such claims are successful, or if we are required to indemnify or defend our customers from these or other claims, these matters could be disruptive to our business and management and have a material adverse effect on our business, operating results and financial condition. If we fail to adequately protect our proprietary rights, in the United States and abroad, our competitive position could be impaired and we may lose valuable assets, experience reduced revenue and incur costly litigation to protect our rights. Our success is dependent, in part, upon protecting our proprietary technology. We rely on a combination of copyrights, trademarks, service marks, trade secret laws and contractual restrictions to establish and protect our proprietary rights in our products and services. However, the steps we take to protect our intellectual property may be inadequate. We will not be able to protect our intellectual property if we are unable to enforce our rights or if we do not detect unauthorized use of our intellectual property. Any of our trademarks or other intellectual property rights may be challenged by others or invalidated through administrative process or litigation. Furthermore, legal standards relating to the validity, enforceability and scope of protection of intellectual property rights are uncertain. Despite our precautions, it may be possible for unauthorized third parties to copy our technology and use information that we regard as proprietary to create products and services that compete with ours. Some license provisions protecting against unauthorized use, copying, transfer and disclosure of our offerings may be unenforceable under the laws of certain jurisdictions and foreign countries. In addition, the laws of some countries do not protect proprietary rights to the same extent as the laws of the United States. To the extent we expand our international activities, our exposure to unauthorized copying and use of our technology and proprietary information may increase. 23 We enter into confidentiality and invention assi gnment agreements with our employees and consultants and enter into confidentiality agreements with the parties with whom we have strategic relationships and business alliances. No assurance can be given that these agreements will be effective in controlli ng access to and distribution of our products and proprietary information. Further, these agreements may not prevent our competitors from independently developing technologies that are substantially equivalent or superior to our platform and offerings. We may be required to spend significant resources to monitor and protect our intellectual property rights. Litigation may be necessary in the future to enforce our intellectual property rights and to protect our trade secrets. Such litigation could be costly, time consuming and distracting to management and could result in the impairment or loss of portions of our intellectual property. Furthermore, our efforts to enforce our intellectual property rights may be met with defenses, counterclaims and countersuits attacking the validity and enforceability of our intellectual property rights. Our inability to protect our proprietary technology against unauthorized copying or use, as well as any costly litigation, could delay further sales or the implementation of our platform and offerings, impair the functionality of our platform and offerings, delay introductions of new features or enhancements, result in our substituting inferior or more costly technologies into our platform and offerings, or injure our reputation. Our use of “open source” software could negatively affect our ability to offer our platform and subject us to possible litigation. A substantial portion of our cloud-based platform incorporates so-called “open source” software, and we may incorporate additional open source software in the future. Open source software is generally freely accessible, usable and modifiable. Certain open source licenses may, in certain circumstances, require us to offer the components of our platform that incorporate the open source software for no cost, that we make available source code for modifications or derivative works we create based upon, incorporating or using the open source software and that we license such modifications or derivative works under the terms of the particular open source license. If an author or other third party that distributes open source software we use were to allege that we had not complied with the conditions of one or more of these licenses, we could be required to incur significant legal expenses defending against such allegations and could be subject to significant damages, including being enjoined from the offering of the components of our platform that contained the open source software and being required to comply with the foregoing conditions, which could disrupt our ability to offer the affected software. We could also be subject to suits by parties claiming ownership of what we believe to be open source software. Litigation could be costly for us to defend, have a negative effect on our operating results and financial condition and require us to devote additional research and development resources to change our products. Risks Related to Government Regulation and Taxation We could face liability, or our reputation might be harmed, as a result of the activities of our customers, the content of their websites or the data they store on our servers. As a provider of a cloud-based inbound marketing and sales software platform, we may be subject to potential liability for the activities of our customers on or in connection with the data they store on our servers. Although our customer terms of use prohibit illegal use of our services by our customers and permit us to take down websites or take other appropriate actions for illegal use, customers may nonetheless engage in prohibited activities or upload or store content with us in violation of applicable law or the customer’s own policies, which could subject us to liability or harm our reputation. Several U.S. federal statutes may apply to us with respect to various customer activities: • • The Digital Millennium Copyright Act of 1998, or DMCA, provides recourse for owners of copyrighted material who believe that their rights under U.S. copyright law have been infringed on the Internet. Under the DMCA, based on our current business activity as an Internet service provider that does not own or control website content posted by our customers, we generally are not liable for infringing content posted by our customers or other third parties, provided that we follow the procedures for handling copyright infringement claims set forth in the DMCA. Generally, if we receive a proper notice from, or on behalf, of a copyright owner alleging infringement of copyrighted material located on websites we host, and we fail to expeditiously remove or disable access to the allegedly infringing material or otherwise fail to meet the requirements of the safe harbor provided by the DMCA, the copyright owner may seek to impose liability on us. Technical mistakes in complying with the detailed DMCA take-down procedures could subject us to liability for copyright infringement. The Communications Decency Act of 1996, or CDA, generally protects online service providers, such as us, from liability for certain activities of their customers, such as the posting of defamatory or obscene content, unless the online service provider is participating in the unlawful conduct. Under the CDA, we are generally not responsible for the customer-created content hosted on our servers. Consequently, we do not monitor hosted websites or prescreen the content placed by our customers on their sites. However, the CDA does not apply in foreign jurisdictions and we may nonetheless be brought into disputes between our customers and third parties which would require us to devote management time and 24 resources to resolve such matters and any publicity from such matters could also have an ad verse effect on our reputation and therefore our business. • In addition to the CDA, the Securing the Protection of our Enduring and Established Constitutional Heritage Act, or the SPEECH Act, provides a statutory exception to the enforcement by a U.S. court of a foreign judgment for defamation under certain circumstances. Generally, the exception applies if the defamation law applied in the foreign court did not provide at least as much protection for freedom of speech and press as would be provided by the First Amendment of the U.S. Constitution or by the constitution and law of the state in which the U.S. court is located, or if no finding of defamation would be supported under the First Amendment of the U.S. Constitution or under the constitution and law of the state in which the U.S. court is located. Although the SPEECH Act may protect us from the enforcement of foreign judgments in the United States, it does not affect the enforceability of the judgment in the foreign country that issued the judgment. Given our international presence, we may therefore, nonetheless, have to defend against or comply with any foreign judgments made against us, which could take up substantial management time and resources and damage our reputation. Although these statutes and case law in the United States have generally shielded us from liability for customer activities to date, court rulings in pending or future litigation may narrow the scope of protection afforded us under these laws. In addition, laws governing these activities are unsettled in many international jurisdictions, or may prove difficult or impossible for us to comply with in some international jurisdictions. Also, notwithstanding the exculpatory language of these bodies of law, we may become involved in complaints and lawsuits which, even if ultimately resolved in our favor, add cost to our doing business and may divert management’s time and attention. Finally, other existing bodies of law, including the criminal laws of various states, may be deemed to apply or new statutes or regulations may be adopted in the future, any of which could expose us to further liability and increase our costs of doing business. We may be subject to additional obligations to collect and remit sales tax and other taxes, and we may be subject to tax liability for past sales, which could harm our business. State, local and foreign jurisdictions have differing rules and regulations governing sales, use, value added and other taxes, and these rules and regulations are subject to varying interpretations that may change over time. In particular, the applicability of such taxes to our inbound platform in various jurisdictions is unclear. Further, these jurisdictions’ rules regarding tax nexus are complex and vary significantly. As a result, we could face the possibility of tax assessments and audits, and our liability for these taxes and associated penalties could exceed our original estimates. A successful assertion that we should be collecting additional sales, use, value added or other taxes in those jurisdictions where we have not historically done so and do not accrue for such taxes could result in substantial tax liabilities and related penalties for past sales, discourage customers from purchasing our application or otherwise harm our business and operating results. Changes in tax laws or regulations that are applied adversely to us or our customers could increase the costs of our inbound platform and adversely impact our business. New income, sales, use or other tax laws, statutes, rules, regulations or ordinances could be enacted at any time. Any new taxes could adversely affect our domestic and international business operations, and our business and financial performance. Further, existing tax laws, statutes, rules, regulations or ordinances could be interpreted, changed, modified or applied adversely to us. These events could require us or our customers to pay additional tax amounts on a prospective or retroactive basis, as well as require us or our customers to pay fines and/or penalties and interest for past amounts deemed to be due. If we raise our prices to offset the costs of these changes, existing and potential future customers may elect not to continue or purchase our inbound platform in the future. Additionally, new, changed, modified or newly interpreted or applied tax laws could increase our customers’ and our compliance, operating and other costs, as well as the costs of our platform. Any or all of these events could adversely impact our business and financial performance. We are a multinational organization faced with increasingly complex tax issues in many jurisdictions, and we could be obligated to pay additional taxes in various jurisdictions. As a multinational organization, we may be subject to taxation in several jurisdictions around the world with increasingly complex tax laws, the application of which can be uncertain. The amount of taxes we pay in these jurisdictions could increase substantially as a result of changes in the applicable tax principles, including increased tax rates, new tax laws or revised interpretations of existing tax laws and precedents, which could have a material adverse effect on our liquidity and operating results. Changes in tax laws, such as tax reform in the United States or changes in tax laws resulting from the Organization for Economic Co-operation and Development’s multi-jurisdictional plan of action to address “base erosion and profit shifting,” could impact our effective tax rate. In addition, the authorities in these jurisdictions could review our tax returns and impose additional tax, interest and penalties, and the authorities could claim that various withholding requirements apply to us or our subsidiaries or assert that benefits of tax treaties are not available to us or our subsidiaries, any of which could have a material impact on us and the results of our operations. 25 Failure to comply with laws and regulations could harm our business. Our business is subject to regulation by various federal, state, local and foreign governmental agencies, including agencies responsible for monitoring and enforcing employment and labor laws, workplace safety, environmental laws, consumer protection laws, anti-bribery laws, import/export controls, federal securities laws and tax laws and regulations. In certain jurisdictions, these regulatory requirements may be more stringent than those in the United States. Noncompliance with applicable regulations or requirements could subject us to investigations, sanctions, mandatory recalls, enforcement actions, disgorgement of profits, fines, damages, civil and criminal penalties or injunctions. Comprehensive Tax Reform Legislation Could Adversely Affect Our Business And Financial Condition. The U.S. government has recently enacted comprehensive tax legislation that includes significant changes to the taxation of business entities, referenced herein as the Tax Reform Act. These changes include, among others, a permanent reduction to the corporate income tax rate, limiting interest deductions, allowing for the expensing of capital expenditures, and putting into effect the migration from a “worldwide” system of taxation to a territorial system. The overall impact of this tax reform is uncertain, and it is possible that our business and financial condition could be adversely affected. We continue to examine the impact this tax reform legislation may have on our business. We urge our shareholders to consult with their legal and tax advisors with respect to any such legislation and the potential tax consequences of investing in our ordinary shares. We may not be able to utilize a significant portion of our net operating loss carryforwards, which could adversely affect our profitability. As of December 31, 2017, we had federal and state net operating loss carryforwards due to prior period losses, which, if not utilized, will begin to expire in 2027 for federal purposes and begin to expire in 2023 for state purposes. These net operating loss carryforwards could expire unused and be unavailable to offset future income tax liabilities, which could adversely affect our profitability. In addition, under Section 382 of the Internal Revenue Code of 1986, as amended, which we refer to as the Code, our ability to utilize net operating loss carryforwards or other tax attributes, such as research tax credits, in any taxable year may be further limited if we experience an ownership change. A Section 382 ownership change generally occurs if one or more stockholders or groups of stockholders who own at least 5% of our stock increase their ownership by more than 50 percentage points over their lowest ownership percentage within a rolling three-year period. Similar rules may apply under state tax laws. Future issuances of our stock could cause an ownership change. It is possible that an ownership change in connection with a future offering, or any future ownership change, could have a material effect on the use of our net operating loss carryforwards or other tax attributes, which could adversely affect our profitability. Net operating loss carryforwards incurred for periods beginning on or after January 1, 2018, are not subject to these limitations. The standards that private entities use to regulate the use of email have in the past interfered with, and may in the future interfere with, the effectiveness of our inbound platform and our ability to conduct business. Our customers rely on email to communicate with their existing or prospective customers. Various private entities attempt to regulate the use of email for commercial solicitation. These entities often advocate standards of conduct or practice that significantly exceed current legal requirements and classify certain email solicitations that comply with current legal requirements as spam. Some of these entities maintain “blacklists” of companies and individuals, and the websites, internet service providers and internet protocol addresses associated with those entities or individuals that do not adhere to those standards of conduct or practices for commercial email solicitations that the blacklisting entity believes are appropriate. If a company’s internet protocol addresses are listed by a blacklisting entity, emails sent from those addresses may be blocked if they are sent to any internet domain or internet address that subscribes to the blacklisting entity’s service or purchases its blacklist. From time to time, some of our internet protocol addresses may become listed with one or more blacklisting entities due to the messaging practices of our customers. There can be no guarantee that we will be able to successfully remove ourselves from those lists. Blacklisting of this type could interfere with our ability to market our inbound platform and services and communicate with our customers and, because we fulfill email delivery on behalf of our customers, could undermine the effectiveness of our customers’ email marketing campaigns, all of which could have a material negative impact on our business and results of operations. 26 Existing federal, state and foreign laws regulate Internet trackin g software, the senders of commercial emails and text messages, website owners and other activities, and could impact the use of our inbound platform and potentially subject us to regulatory enforcement or private litigation. Certain aspects of how our customers utilize our platform are subject to regulations in the United States, European Union and elsewhere. In recent years, U.S. and European lawmakers and regulators have expressed concern over the use of third-party cookies or web beacons for online behavioral advertising, and legislation adopted recently in the European Union requires informed consent for the placement of a cookie on a user’s device. Regulation of cookies and web beacons may lead to restrictions on our activities, such as efforts to understand users’ Internet usage. New and expanding “Do Not Track” regulations have recently been enacted or proposed that protect users’ right to choose whether or not to be tracked online. These regulations seek, among other things, to allow end users to have greater control over the use of private information collected online, to forbid the collection or use of online information, to demand a business to comply with their choice to opt out of such collection or use, and to place limits upon the disclosure of information to third party websites. These policies could have a significant impact on the operation of our inbound platform and could impair our attractiveness to customers, which would harm our business. Many of our customers and potential customers in the healthcare, financial services and other industries are subject to substantial regulation regarding their collection, use and protection of data and may be the subject of further regulation in the future. Accordingly, these laws or significant new laws or regulations or changes in, or repeals of, existing laws, regulations or governmental policy may change the way these customers do business and may require us to implement additional features or offer additional contractual terms to satisfy customer and regulatory requirements, or could cause the demand for and sales of our inbound platform to decrease and adversely impact our financial results. In addition, the Controlling the Assault of Non-Solicited Pornography and Marketing Act of 2003, or the CAN-SPAM Act, establishes certain requirements for commercial email messages and specifies penalties for the transmission of commercial email messages that are intended to deceive the recipient as to source or content. The CAN-SPAM Act, among other things, obligates the sender of commercial emails to provide recipients with the ability to opt out of receiving future commercial emails from the sender. The ability of our customers’ message recipients to opt out of receiving commercial emails may minimize the effectiveness of the email components of our inbound platform. In addition, certain states and foreign jurisdictions, such as Australia, Canada and the European Union, have enacted laws that regulate sending email, and some of these laws are more restrictive than U.S. laws. For example, some foreign laws prohibit sending unsolicited email unless the recipient has provided the sender advance consent to receipt of such email, or in other words has “opted-in” to receiving it. A requirement that recipients opt into, or the ability of recipients to opt out of, receiving commercial emails may minimize the effectiveness of our platform. While these laws and regulations generally govern our customers’ use of our platform, we may be subject to certain laws as a data processor on behalf of, or as a business associate of, our customers. For example, laws and regulations governing the collection, use and disclosure of personal information include, in the United States, rules and regulations promulgated under the authority of the Federal Trade Commission, the Health Insurance Portability and Accountability Act of 1996, the Gramm-Leach-Bliley Act of 1999 and state breach notification laws, and internationally, the Data Protection Directive in the European Union and the Federal Data Protection Act in Germany. If we were found to be in violation of any of these laws or regulations as a result of government enforcement or private litigation, we could be subjected to civil and criminal sanctions, including both monetary fines and injunctive action that could force us to change our business practices, all of which could adversely affect our financial performance and significantly harm our reputation and our business. We are subject to governmental export controls and economic sanctions laws that could impair our ability to compete in international markets and subject us to liability if we are not in full compliance with applicable laws. Our business activities are subject to various restrictions under U.S. export controls and trade and economic sanctions laws, including the U.S. Commerce Department’s Export Administration Regulations and economic and trade sanctions regulations maintained by the U.S. Treasury Department’s Office of Foreign Assets Control. If we fail to comply with these laws and regulations, we and certain of our employees could be subject to civil or criminal penalties and reputational harm. Obtaining the necessary authorizations, including any required license, for a particular transaction may be time-consuming, is not guaranteed, and may result in the delay or loss of sales opportunities. Furthermore, U.S. export control laws and economic sanctions laws prohibit certain transactions with U.S. embargoed or sanctioned countries, governments, persons and entities. Although we take precautions to prevent transactions with U.S. sanction targets, the possibility exists that we could inadvertently provide our solutions to persons prohibited by U.S. sanctions. This could result in negative consequences to us, including government investigations, penalties and reputational harm. 27 Risks Related to Our Operating Results and Financial Condition We may experience quarterly fluctuations in our operating results due to a number of factors, which makes our future results difficult to predict and could cause our operating results to fall below expectations or our guidance. Our quarterly operating results have fluctuated in the past and are expected to fluctuate in the future due to a variety of factors, many of which are outside of our control. As a result, our past results may not be indicative of our future performance, and comparing our operating results on a period-to-period basis may not be meaningful. In addition to the other risks described in this Annual Report on Form 10-K, factors that may affect our quarterly operating results include the following: • • • • • • • • • • • • • changes in spending on marketing and sales software by our current or prospective customers; pricing our inbound platform subscriptions effectively so that we are able to attract and retain customers without compromising our profitability; attracting new customers for both our marketing and sales software, increasing our existing customers’ use of our platform and providing our customers with excellent customer support; customer renewal rates and the amounts for which agreements are renewed; global awareness of our thought leadership and brand; changes in the competitive dynamics of our market, including consolidation among competitors or customers and the introduction of new products or product enhancements; changes to the commission plans, quotas and other compensation-related metrics for our sales representatives; the amount and timing of payment for operating expenses, particularly research and development, sales and marketing expenses and employee benefit expenses; the amount and timing of costs associated with recruiting, training and integrating new employees while maintaining our company culture; our ability to manage our existing business and future growth, including increases in the number of customers on our platform and the introduction and adoption of our inbound platform in new markets outside of the United States; unforeseen costs and expenses related to the expansion of our business, operations and infrastructure, including disruptions in our hosting network infrastructure and privacy and data security; foreign currency exchange rate fluctuations; and general economic and political conditions in our domestic and international markets. We may not be able to accurately forecast the amount and mix of future subscriptions, revenue and expenses and, as a result, our operating results may fall below our estimates or the expectations of public market analysts and investors. If our revenue or operating results fall below the expectations of investors or securities analysts, or below any guidance we may provide, the price of our common stock could decline. If we do not accurately predict subscription renewal rates or otherwise fail to forecast our revenue accurately, or if we fail to match our expenditures with corresponding revenue, our operating results could be adversely affected. Because our recent growth has resulted in the rapid expansion of our business, we do not have a long history upon which to base forecasts of renewal rates with customers or future operating revenue. As a result, our operating results in future reporting periods may be significantly below the expectations of the public market, equity research analysts or investors, which could harm the price of our common stock. Because we generally recognize revenue from subscriptions ratably over the term of the agreement, near term changes in sales may not be reflected immediately in our operating results. We offer our inbound platform primarily through a mix of monthly, quarterly and single-year subscription agreements and generally recognize revenue ratably over the related subscription period. As a result, much of the revenue we report in each quarter is derived from agreements entered into during prior months, quarters or years. In addition, we do not record deferred revenue beyond amounts invoiced as a liability on our balance sheet. A decline in new or renewed subscriptions or marketing solutions agreements in any one quarter is not likely to be reflected immediately in our revenue results for that quarter. Such declines, however, would negatively affect our revenue and deferred revenue balances in future periods, and the effect of significant downturns in sales and market acceptance of our platform, and potential changes in our rate of renewals, may not be fully reflected in our results of operations until future periods. Our subscription model also makes it difficult for us to rapidly increase our total revenue and deferred revenue balance through additional sales in any period, as revenue from new customers must be recognized over the applicable subscription term. 28 Servicing our debt may require a significant amount of cash. We may not have sufficient cash flow from our business to pay our indebtedness , and we may not have the ability to raise the funds necessary to settle for cash conversions of the 2022 Notes or to repurchase the 2022 Notes for cash upon a fundamental change, which could adversely affect our business and results of operations . We incurred indebtedness in the aggregate principal amount of $400.0 million in connection with the issuance of our 0.25% convertible senior notes due June 1, 2022 (the “2022 Notes”). Our ability to make scheduled payments of the principal of, to pay interest on or to refinance our indebtedness, including the 2022 Notes, depends on our future performance, which is subject to economic, financial, competitive and other factors beyond our control. Our business may not continue to generate cash flow from operations in the future sufficient to service our debt and make necessary capital expenditures. If we are unable to generate such cash flow, we may be required to adopt one or more alternatives, such as selling assets, restructuring debt or obtaining additional debt financing or equity capital on terms that may be onerous or highly dilutive. Our ability to refinance any future indebtedness will depend on the capital markets and our financial condition at such time. We may not be able to engage in any of these activities or engage in these activities on desirable terms, which could result in a default on our debt obligations. In addition, any of our future debt agreements may contain restrictive covenants that may prohibit us from adopting any of these alternatives. Our failure to comply with these covenants could result in an event of default which, if not cured or waived, could result in the acceleration of our debt. In addition, holders of the 2022 Notes have the right to require us to repurchase their 2022 Notes upon the occurrence of a fundamental change at a fundamental change repurchase price equal to 100% of the principal amount of the 2022 Notes to be repurchased, plus accrued and unpaid interest, if any. Upon conversion of the 2022 Notes, unless we elect to deliver solely shares of our common stock to settle such conversion (other than paying cash in lieu of delivering any fractional share), we will be required to make cash payments in respect of the 2022 Notes being converted. We may not have enough available cash or be able to obtain financing at the time we are required to make repurchases of 2022 Notes surrendered therefor or 2022 Notes being converted. In addition, our ability to repurchase the 2022 Notes or to pay cash upon conversions of the 2022 Notes may be limited by law, by regulatory authority or by agreements governing our future indebtedness. Our failure to repurchase 2022 Notes at a time when the repurchase is required by the indenture governing the notes or to pay any cash payable on future conversions of the 2022 Notes as required by such indenture would constitute a default under such indenture. A default under the indenture or the fundamental change itself could also lead to a default under agreements governing our future indebtedness. If the repayment of the related indebtedness were to be accelerated after any applicable notice or grace periods, we may not have sufficient funds to repay the indebtedness and repurchase the 2022 Notes or make cash payments upon conversions thereof. In addition, our indebtedness, combined with our other financial obligations and contractual commitments, could have other important consequences. For example, it could: • • • • make us more vulnerable to adverse changes in general U.S. and worldwide economic, industry and competitive conditions and adverse changes in government regulation; limit our flexibility in planning for, or reacting to, changes in our business and our industry; place us at a disadvantage compared to our competitors who have less debt; and limit our ability to borrow additional amounts to fund acquisitions, for working capital and for other general corporate purposes. Any of these factors could materially and adversely affect our business, financial condition and results of operations. In addition, if we incur additional indebtedness, the risks related to our business and our ability to service or repay our indebtedness would increase. The conditional conversion feature of the 2022 Notes, if triggered, may adversely affect our financial condition and operating results. In the event the conditional conversion feature of the 2022 Notes is triggered, holders of 2022 Notes will be entitled to convert the 2022 Notes at any time during specified periods at their option. If one or more holders elect to convert their 2022 Notes, unless we elect to satisfy our conversion obligation by delivering solely shares of our common stock (other than paying cash in lieu of delivering any fractional share), we would be required to settle a portion or all of our conversion obligation through the payment of cash, which could adversely affect our liquidity. In addition, even if holders do not elect to convert their 2022 Notes, we could be required under applicable accounting rules to reclassify all or a portion of the outstanding principal of the 2022 Notes as a current rather than long-term liability, which would result in a material reduction of our net working capital. 29 The accounting method for convertible debt securities that may be settled in cash, such as the 2022 Not es, could have a material effect on our reported financial results. Under Financial Accounting Standards Board Accounting Standards Codification 470-20, Debt with Conversion and Other Options , which we refer to as ASC 470-20, an entity must separately account for the liability and equity components of convertible debt instruments (such as the 2022 Notes) that may be settled entirely or partially in cash upon conversion in a manner that reflects the issuer’s economic interest cost. ASC 470-20 requires the value of the conversion option of the 2022 Notes, representing the equity component, to be recorded as additional paid-in capital within stockholders’ equity in our consolidated balance sheet and as a discount to the 2022 Notes, which reduces their initial carrying value. The carrying value of the 2022 Notes, net of the discount recorded, will be accreted up to the principal amount of the 2022 Notes from the issuance date until maturity, which will result in non-cash charges to interest expense in our consolidated statement of operations. Accordingly, we will report lower net income or higher net loss in our financial results because ASC 470-20 requires interest to include both the current period’s accretion of the debt discount and the instrument’s coupon interest, which could adversely affect our reported or future financial results, the trading price of our common stock and the trading price of the 2022 Notes. In addition, under certain circumstances, convertible debt instruments (such as the 2022 Notes) that may be settled entirely or partly in cash are currently accounted for utilizing the treasury stock method, the effect of which is that the shares issuable upon conversion of the 2022 Notes are not included in the calculation of diluted earnings per share except to the extent that the conversion value of the 2022 Notes exceeds their principal amount. Under the treasury stock method, for diluted earnings per share purposes, the transaction is accounted for as if the number of shares of common stock that would be necessary to settle such excess, if we elected to settle such excess in shares, are issued. We cannot be sure that the accounting standards in the future will continue to permit the use of the treasury stock method. If we are unable to use the treasury stock method in accounting for the shares issuable upon conversion of the 2022 Notes, then our diluted earnings per share would be adversely affected. We are exposed to fluctuations in currency exchange rates. We face exposure to movements in currency exchange rates, which may cause our revenue and operating results to differ materially from expectations. As we have expanded our international operations our exposure exchange rate fluctuations has increased, in particular with respect to the Euro, British Pound Sterling, Australian Dollar, and Japanese Yen. As exchange rates vary, revenue, cost of revenue, operating expenses and other operating results, when re-measured, may differ materially from expectations. In addition, our operating results are subject to fluctuation if our mix of U.S. and foreign currency denominated transactions and expenses changes in the future. Although we may apply certain strategies to mitigate foreign currency risk, these strategies might not eliminate our exposure to foreign exchange rate fluctuations and would involve costs and risks of their own, such as ongoing management time and expertise, external costs to implement the strategies and potential accounting implications. Additionally, as we anticipate growing our business further outside of the United States, the effects of movements in currency exchange rates will increase as our transaction volume outside of the United States increases. Risks Related to Our Common Stock Our stock price may be volatile and you may be unable to sell your shares at or above the price you purchased them. The trading prices of the securities of technology companies, including providers of software via the cloud-based model, have been highly volatile. Since shares of our common stock were sold in our initial public offering in October 2014 at a price of $25.00 per share, our stock price has ranged from $25.79 to $93.53 , through December 31, 2017. The market price of our common stock may fluctuate significantly in response to numerous factors, many of which are beyond our control, including: • • • • • actual or anticipated fluctuations in our revenue and other operating results, including as a result of the addition or loss of any number of customers; announcements by us or our competitors of significant technical innovations, acquisitions, strategic partnerships, joint ventures or capital commitments; the financial projections we may provide to the public, any changes in these projections or our failure to meet these projections; failure of securities analysts to initiate or maintain coverage of us, changes in ratings and financial estimates and the publication of other news by any securities analysts who follow our company, or our failure to meet these estimates or the expectations of investors; changes in operating performance and stock market valuations of cloud-based software or other technology companies, or those in our industry in particular; 30 • • • • • • price and volume fluctuations in the trading of our common stock and in the overall stock market, in cluding as a result of trends in the economy as a whole; sales of large blocks of our common stock or the dilutive effect of our 2022 Notes or any other equity or equity-linked financings; new laws or regulations or new interpretations of existing laws or regulations applicable to our business or industry, including data privacy and data security; lawsuits threatened or filed against us; changes in key personnel; and other events or factors, including changes in general economic, industry and market conditions and trends. In addition, the stock markets have experienced extreme price and volume fluctuations that have affected and continue to affect the market prices of equity securities of many technology companies. Stock prices of many technology companies have fluctuated in a manner unrelated or disproportionate to the operating performance of those companies. In the past, stockholders have instituted securities class action litigation following periods of market volatility. If we were to become involved in securities litigation, it could subject us to substantial costs, divert resources and the attention of management from our business and adversely affect our business. We have incurred, and expect to continue to incur, increased costs and demands upon management as a result of complying with the laws and regulations affecting public companies, which could adversely affect our business, operating results and financial condition. As a public company we have incurred, and expect to continue to incur significant legal, accounting and other expenses. We are subject to the reporting requirements of the Securities Exchange Act of 1934, as amended, or the Exchange Act, the Sarbanes-Oxley Act of 2002, or the Sarbanes-Oxley Act, the Dodd- Frank Wall Street Reform and Consumer Protection Act, or the Dodd-Frank Act, and the rules and regulations of the New York Stock Exchange, or NYSE. These requirements have increased and will continue to increase our legal, accounting and financial compliance costs and have made and will continue to make some activities more time consuming and costly. For example, we expect these rules and regulations to make it more difficult and more expensive for us to obtain director and officer liability insurance, and we may be required to accept reduced policy limits and coverage or incur substantially higher costs to maintain the same or similar coverage. As a result, it may be more difficult for us to attract and retain qualified individuals to serve on our board of directors or as our executive officers. The Sarbanes-Oxley Act requires, among other things, that we assess the effectiveness of our internal control over financial reporting annually and the effectiveness of our disclosure controls and procedures quarterly. In particular, Section 404 of the Sarbanes-Oxley Act, or Section 404, requires us to perform system and process evaluation and testing of our internal control over financial reporting to allow management to report on, and our independent registered public accounting firm to attest to, the effectiveness of our internal control over financial reporting. Our compliance with applicable provisions of Section 404 requires that we incur substantial accounting expense and expend significant management time on compliance-related issues as we implement additional corporate governance practices and comply with reporting requirements. Moreover, if we are not able to comply with the requirements of Section 404 applicable to us in a timely manner, or if we or our independent registered public accounting firm identifies deficiencies in our internal control over financial reporting that are deemed to be material weaknesses, the market price of our stock could decline and we could be subject to sanctions or investigations by the SEC or other regulatory authorities, which would require additional financial and management resources. We have in the past identified control deficiencies, including a material weakness during the quarters ended June 30, 2015 and September 30, 2015. While we remediated this material weakness in 2015 and continue to seek improvements to enhance our control environment, we may identify additional material weaknesses or other deficiencies in the future. Furthermore, investor perceptions of our company may suffer if deficiencies are found, and this could cause a decline in the market price of our stock. Irrespective of compliance with Section 404, any failure of our internal control over financial reporting could have a material adverse effect on our stated operating results and harm our reputation. If we are unable to implement these requirements effectively or efficiently, it could harm our operations, financial reporting, or financial results and could result in an adverse opinion on our internal controls from our independent registered public accounting firm. 31 Our ability to raise capital in the future may be limited, and our failure to raise capital when needed could prevent us from growing. Our business and operations may consume resources faster than we anticipate. In the future, we may need to raise additional funds to invest in future growth opportunities. Additional financing may not be available on favorable terms, if at all. If adequate funds are not available on acceptable terms, we may be unable to invest in future growth opportunities, which could seriously harm our business and operating results. If we incur debt, the debt holders would have rights senior to common stockholders to make claims on our assets, and the terms of any debt could restrict our operations, including our ability to pay dividends on our common stock. Furthermore, if we issue equity securities, stockholders will experience dilution, and the new equity securities could have rights senior to those of our common stock. The 2022 Notes are and any additional equity or equity-linked financings would be dilutive to our stockholders. Because our decision to issue securities in any future offering will depend on market conditions and other factors beyond our control, we cannot predict or estimate the amount, timing or nature of our future offerings. As a result, our stockholders bear the risk of our future securities offerings reducing the market price of our common stock and diluting their interest. Anti-takeover provisions in our charter documents and Delaware law may delay or prevent an acquisition of our company. Our amended and restated certificate of incorporation, amended and restated bylaws and Delaware law contain provisions that may have the effect of delaying or preventing a change in control of us or changes in our management. Our amended and restated certificate of incorporation and bylaws include provisions that: • • • • • • • • • • authorize “blank check” preferred stock, which could be issued by the board without stockholder approval and may contain voting, liquidation, dividend and other rights superior to our common stock; provide for a classified board of directors whose members serve staggered three-year terms; specify that special meetings of our stockholders can be called only by our board of directors, the chairperson of the board, the chief executive officer or the president; prohibit stockholder action by written consent; establish an advance notice procedure for stockholder approvals to be brought before an annual meeting of our stockholders, including proposed nominations of persons for election to our board of directors; provide that our directors may be removed only for cause; provide that vacancies on our board of directors may be filled only by a majority of directors then in office, even though less than a quorum; specify that no stockholder is permitted to cumulate votes at any election of directors; authorize our board of directors to modify, alter or repeal our amended and restated bylaws; and require supermajority votes of the holders of our common stock to amend specified provisions of our charter documents. These provisions, alone or together, could delay or prevent hostile takeovers and changes in control or changes in our management. In addition, because we are incorporated in Delaware, we are governed by the provisions of Section 203 of the Delaware General Corporation Law, which limits the ability of stockholders owning in excess of 15% of our outstanding voting stock to merge or combine with us in certain circumstances. Any provision of our amended and restated certificate of incorporation or amended and restated bylaws or Delaware law that has the effect of delaying or deterring a change in control could limit the opportunity for our stockholders to receive a premium for their shares of our common stock, and could also affect the price that some investors are willing to pay for our common stock. ITEM 1B. UNRESOLVED STAFF COMMENTS None. 32 ITEM 2. Pr operties We occupy approximately 280,000 square feet of office space in Cambridge, Massachusetts pursuant to lease agreements that expire through 2027. We also maintain offices in Portsmouth, New Hampshire, Dublin, Ireland, Sydney, Australia, Singapore, Japan, and Berlin. We believe that our current facilities are suitable and adequate to meet our current needs. We intend to add new facilities or expand existing facilities as we add employees, and we believe that suitable additional or substitute space will be available as needed to accommodate any such expansion of our operations. ITEM 3. Legal Proceedings From time to time we may become involved in legal proceedings or be subject to claims arising in the ordinary course of our business. Although the results of litigation and claims cannot be predicted with certainty, we currently believe that the ultimate costs to resolve any pending matter will not have a material adverse effect on our business, operating results, financial condition or cash flows. Regardless of the outcome, litigation can have an adverse impact on us because of defense and settlement costs, diversion of management resources and other factors. ITEM 4. Mine Safety Disclosures Not Applicable. 33 PART II ITEM 5. Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities Market Information for Common Stock Our common stock has been listed on the New York Stock Exchange under the symbol “HUBS” since October 9, 2014.

Management’s Discussion and Analysis of Financial Condition and Results of Operations The following discussion and analysis of our financial condition and results of operations should be read in conjunction with our consolidated financial statements and related notes that appear elsewhere in this Annual Report on Form 10-K. As discussed in the section titled “Special Note Regarding Forward- Looking Statements,” the following discussion and analysis contains forward-looking statements that involve risks and uncertainties, as well as assumptions that, if they never materialize or prove incorrect, could cause our results to differ materially from those expressed or implied by such forward-looking statements. Factors that could cause or contribute to such differences include, but are not limited to, those identified below, and those discussed in the section titled “Risk Factors” included under Part I, Item 1A within this Annual Report on Form 10-K. Company Overview We provide a cloud-based marketing and sales software platform, which we refer to as our Software Platform, that enables businesses to deliver an inbound experience. An inbound marketing and sales experience attracts, engages and delights customers by being more relevant, more helpful, more personalized and less interruptive than traditional marketing and sales tactics. Our Software Platform features integrated applications to help businesses attract visitors to their websites, convert visitors into leads, close leads into customers and delight customers so that they become promoters of those businesses. These integrated applications include social media, search engine optimization, blogging, website content management, marketing automation, email, sales productivity, CRM, analytics and reporting. We designed our all-in-one Software Platform from the ground up to enable businesses to provide an inbound experience to their prospects and customers. At the core of our Software Platform is a single inbound contacts database for each business that captures its lead and customer activity throughout the customer lifestyle. Our Software Platform uses our centralized inbound contacts database to empower businesses to create more personalized interactions with customers, such as personalized emails, personalized social media alerts, personalized websites and targeted alerts for sales people. We provide a comprehensive set of integrated applications on our Software Platform, which offers businesses ease of use, power and simplicity. We designed and built our Software Platform to serve a large numbers of customers of any size with demanding use cases. While our Software Platform can scale to the enterprise, we focus on selling to mid-market businesses because we believe we have significant competitive advantages attracting and serving them. We efficiently reach these businesses at scale through our proven inbound go-to-market approach and our marketing agency and sales partners, which we refer to as Partners. Our Software Platform is particularly suited to serving the needs of mid-market business-to-business companies. These mid-market businesses seek an integrated, easy to implement and easy to use solution to reach customers and compete with organizations that have larger marketing and sales budgets. As of December 31, 2017, we had 41,593 total customers of varying sizes in more than 90 countries, representing almost every industry. Our Software Platform is a multi-tenant, single code-based and globally available software-as-a-service product delivered through web browsers or mobile applications. We sell our Software Platform on a subscription basis and generated revenue of $375.6 million in 2017, $271.0 million in 2016, and $181.9 million in 2015, representing year-over-year increases of 39% in 2017 and 49% in 2016. We had net losses of $39.7 million in 2017, $45.6 million in 2016, and $46.1 million in 2015, primarily due to investments in our growth. We derive most of our revenue from subscriptions to our cloud-based Software Platform and related professional services, which consist of customer on- boarding and training services. Subscription revenue accounted for 95% of our total revenue for the year ended December 31, 2017, 94% of our total revenue for the year ended December 31, 2016, and 92% of our total revenue in the year ended December 31, 2015. We sell multiple product plans at different base prices on a subscription basis, each of which includes our core Software Platform and integrated applications to meet the needs of the various customers we serve. Customers pay additional fees if the number of contacts stored and tracked in the customer’s database exceeds specified thresholds. We generate additional revenue based on the purchase of additional subscriptions, purchase of additional products, purchases of our add-on products and the number of account users, subdomains and website visits. Substantially all of our customers’ subscriptions are one year or less in duration. Subscriptions are non-cancelable and are billed in advance on various schedules. Because the mix of billing terms for orders can vary from period to period, the annualized value of the orders we enter into with our customers will not be completely reflected in deferred revenue at any single point in time. Accordingly, we do not believe that change in deferred revenue is an accurate indicator of future revenue for a given period of time. Many of our customers purchase on-boarding and training services which are designed to help customers enhance their ability to attract, engage and delight their customers using our platform Professional services and other revenue accounted for 5% of total revenue for the year ended December 31, 2017, 6% of total revenue for the year ended December 31, 2016 and 8% of our total revenue for the year ended December 31, 2015. We expect professional services and other margins to range from a moderate loss to breakeven for the foreseeable future. 38 We have focused on rapidly growing our busin ess and plan to continue to make investments to help us address some of the challenges facing us to support this growth, such as demand for our platform by existing and new customers, significant competition from other providers of marketing and sales soft ware and related applications and rapid technological change in our industry. We believe that the growth of our business is dependent on many factors, including our ability to expand our customer base, increase adoption of our Software Platform within exis ting customers, develop new products and applications to extend the functionality of our Software Platform and provide a high level of customer service. We expect to increase our investment in sales and marketing as we continue to expand our sales teams, i ncrease our marketing activities and grow our international operations. We also expect to increase our investment in research and development as we continue to introduce new products and applications to extend the functionality of our Software Platform. We also intend to invest in maintaining a high level of customer service and support which we consider critical for our continued success. We plan to continue investing in our data center infrastructure and services capabilities in order to support continued future customer growth. We also expect to continue to incur additional general and administrative expenses as a result of both our growth and the infrastructure required to be a public company. We expect to use our cash flow from operations and the procee ds from our convertible debt and prior stock offerings to fund these growth strategies and do not expect to be profitable in the near term. We believe that these investments will result in an increase in our subscription revenue base. This will result in revenue increasing faster than the increase in sales and marketing, research and development and general and administrative expenses, exclusive of stock-based compensation, as we reach economies of scale. With this increased operating leverage, we expect our operating margins to increase in the long term. However, we will incur losses in the short term. If we are unable to achieve our revenue growth objectives, including a high rate of renewals of our customer agreements, we may not be able to achieve profitability. Key Business Metrics The following key business metrics are presented in this Annual Report on Form 10-K or in our press release announcing our financial results which is furnished on Form 8-K. We use these key business metrics to evaluate our business, measure our performance, identify trends affecting our business and results of operations, formulate financial projections and make strategic decisions. During the first quarter of 2017, our paid sales product business became a more significant part of our product offerings. To reflect this development, for the periods beginning with the first quarter of 2017, our key business metrics included our paid sales product customers and revenue as described below. These key business metrics may be calculated in a manner different than similar key business metrics used by other companies.

In the sections below comparisons between the years ended December 31, 2017 and December 31, 2016 were performed using our new key business metrics. Comparisons between the years ended December 31, 2016 and December 31, 2015 were performed using our historical key business metrics. Total Customers. We believe that our ability to increase our customer base is an indicator of our market penetration and growth of our business as we continue to expand our sales force and invest in marketing efforts. We define our total customers at the end of a particular period as the number of business entities or individuals with one or more paid subscriptions to our sales or marketing platforms, either paid directly or through a Partner. We do not include in total customers business entities or individuals with one or more paid subscriptions solely for our legacy HubSpot Sales ($10) product. A single customer may have separate paid subscriptions for separate websites, sales licenses or seats, or our marketing and sales platforms, but we count these as one customer if certain customer-provided information such as company name, URL, or email address indicate that these subscriptions are managed by the same business entity or individual. 39 Marketing Customers. Our marketing customers are a sub-set of our total customers. We define marketing customers at the end of a particular period as our total customers, excluding business entities or individuals that have only paid for a subscription to our sales platform. Total Average Subscription Revenue per Customer. We believe that our ability to increase the total average subscription revenue per customer is an indicator of our ability to grow the long-term value of our existing customer relationships. We define total average subscription revenue per customer during a particular period as subscription revenue, excluding revenue from our legacy HubSpot Sales ($10) product, from our total customers during the period divided by the average total customers during the same period. Marketing Average Subscription Revenue per Customer. We define marketing average subscription revenue per customer during a particular period as subscription revenue from our marketing customers during the period, divided by our average marketing customers during the same period. Total Subscription Dollar Retention Rate. We believe that our ability to retain and expand a customer relationship is an indicator of the stability of our revenue base and the long-term value of our customers. We assess our performance in this area using a metric we refer to as our Total Subscription Dollar Retention Rate. We compare the aggregate Total Contractual Monthly Subscription Revenue of our total customer base as of the beginning of each month, which we refer to as Total Retention Base Revenue, to the aggregate Total Contractual Monthly Subscription Revenue of the same group of customers at the end of that month, which we refer to as Total Retained Subscription Revenue. We define Total Contractual Monthly Subscription Revenue as the total amount of subscription fees contractually committed to be paid for a full month under all of our total customer agreements, excluding any commissions owed to our Partners. We do not include in Total Contractual Monthly Subscription Revenue any subscription fees contractually committed to be paid by business entities or individuals with subscriptions for our legacy HubSpot Sales ($10) product. Our Total Subscription Dollar Retention Rate for a given period is calculated by first dividing Total Retained Subscription Revenue by Total Retention Base Revenue for each month in the period, calculating the weighted average of these rates using the Total Retention Base Revenue for each month in the period, and then annualizing the resulting rates. Marketing Subscription Dollar Retention Rate. Our marketing subscription dollar retention rate for a given period is calculated by first dividing Total Retained Marketing Subscription Revenue by Total Retention Base Marketing Revenue for each month in the period, calculating the weighted average of these rates using the Total Retention Base Marketing Revenue for each month in the period, and then annualizing the resulting rates . We compare the aggregate Total Contractual Monthly Marketing Subscription Revenue of our marketing customers as of the beginning of each month, which we refer to as Total Retention Base Marketing Revenue, to the aggregate Total Contractual Monthly Marketing Subscription Revenue of the same group of marketing customers at the end of that month, which we refer to as Total Retained Marketing Subscription Revenue. We define Total Contractual Monthly Marketing Subscription Revenue as the total amount of subscription fees contractually committed to be paid for a full month under all of our marketing customer agreements, excluding any commissions owed to our Partners. Key Components of Consolidated Statements of Operations Revenue We derive our revenue from two major sources, revenue from subscriptions to our inbound Software Platform and professional services and other revenue consisting mainly of on-boarding and training services fees. Subscription based revenue is derived from customers using our Software Platform for their inbound marketing and sales needs. Our Software Platform includes integrated applications that allow businesses to manage social media, search engine optimization, blogging, website content management, marketing automation, email, sales productivity, CRM, analytics and reporting. Substantially all of our customers’ subscriptions are one year or less in duration. Subscriptions are non-cancelable and are billed in advance on various schedules. All subscription fees that are billed in advance of service are recorded in deferred revenue. Subscription based revenue is recognized net of consideration paid to Partners when the Partner purchases the subscription directly from us, as in these instances our customer is the Partner and our remaining obligations are to the Partner. Professional services and other revenue are derived primarily from customer on-boarding and training services. The on-boarding and training services provided to customers typically involves an implementation specialist. An implementation specialist will typically work with our customers to enhance their understanding of how to attract leads and convert them into customers through search engine optimization, social media, blogging and other content. Training is generally sold in connection with a customer’s initial subscription and is billed in advance. The training is also available to be purchased separately following a customer’s purchase of its initial subscription and our Partners routinely provide the same training to customers. The Company recognizes revenue from on- boarding and training services as the services are provided. 40 Cost of Revenue and Operating Expenses Cost of Revenue Cost of subscription revenue consists primarily of managed hosting providers and other third-party service providers, employee-related costs including payroll, benefits and stock-based compensation expense for our customer support team, amortization of capitalized software development costs and acquired technology, and allocated overhead costs, which we define as rent, facilities and costs related to information technology, or IT. Cost of professional services and other revenue consists primarily of personnel costs of our professional services organization, including salaries, benefits, bonuses and stock-based compensation, as well as allocated overhead costs. We expect that cost of subscription and professional services and other revenue will increase in absolute dollars as we continue to invest in growing our business. Over time, we expect to gain benefits of scale associated with our costs of hosting our Software Platform relative to subscription revenues, resulting in improved subscription gross margin. We expect professional services and other margins to range from a moderate loss to breakeven for the foreseeable future. Research and Development Research and development expenses consist primarily of personnel costs of our development team, including payroll, benefits and stock-based compensation expense and allocated overhead costs. We capitalize certain software development costs that are attributable to developing new products and adding incremental functionality to our Software Platform and amortize such costs as costs of subscription revenue over the estimated life of the new product or incremental functionality, which is generally two years. We also capitalize certain development costs that are attributable to developing our customer sales and billing platform and amortize such costs as sales and marketing or general and administrative expense over the estimated life of the customer sales and billing platform, which is generally five years. We focus our research and development efforts on improving our products and developing new ones, delivering new functionality and enhancing the customer experience. We believe delivering new functionalities for our customers is an integral part of our solution and provides our customers with access to a broad array of options and information critical to their marketing efforts. We expect to continue to make investments in and expand our offerings to enhance our customers’ experience and satisfaction and attract new customers. We expect research and development expenses to increase in absolute dollars as we continue to increase the functionality of our Software Platform. Sales and Marketing Sales and marketing expenses consist primarily of personnel costs of our sales and marketing employees, including sales commissions and incentives, benefits and stock-based compensation expense, marketing programs, including lead generation, costs of our annual INBOUND conference, other brand building expenses, amortization of capitalized software development costs associated with our sales and billing platform, and allocated overhead costs. We defer certain sales commissions related to acquiring new customers and amortize them ratably over the term of the corresponding subscription agreement. Sales and marketing expenses also include commissions paid to our Partners when we are the primary obligor for providing the subscription that has been purchased. We plan to continue to expand sales and marketing to grow our customer base and increase sales to existing customers. This growth will include adding sales personnel and expanding our marketing activities to continue to generate additional leads and build brand awareness. We expect sales and marketing expenses will increase as a result of hiring net new quota-carrying sales representatives in the United States and worldwide, adding to the marketing staff and expanding our annual INBOUND conference. Over time, we expect sales and marketing expenses will decline as a percentage of total revenue. General and Administrative General and administrative expenses consist of personnel costs and related expenses for executive, finance, legal, human resources, employee-related information technology, administrative personnel, including payroll, benefits and stock-based compensation expense; professional fees for external legal, accounting and other consulting services, amortization of capitalized software development costs associated with our sales and billing platform, and allocated overhead costs. We expect that general and administrative expenses will increase on an absolute dollar basis but decrease as a percentage of total revenue as we focus on processes, systems and controls to enable our internal support functions to scale with the growth of our business. We also anticipate continuing increases to general and administrative expenses as we incur the costs of compliance associated with being a publicly traded company, including audit and consulting fees. 41 Other Income (Expense) Other income (expense) includes interest income and expense and the impact of foreign currency transaction gains and losses associated with monetary assets and liabilities. The additions of our international offices in Dublin, Ireland in 2013, Sydney, Australia in 2014, Singapore in 2015, Tokyo, Japan in 2016, and Berlin, Germany in 2017 have increased our exposure to foreign currency fluctuations. Income Tax benefit (expense) The income tax benefit (expense) consists of current and deferred taxes for U.S. and foreign jurisdictions. We have historically had a taxable loss in our most significant jurisdiction, the U.S., and a full valuation allowance against the majority of our deferred tax assets. We expect this to continue in the near term. Results of Operations The following tables set forth certain consolidated financial data in dollar amounts and as a percentage of total revenue.

The decrease in average subscription revenue per customer was driven primarily by our continued adoption of our “freemium” model which allows us to add new customers through our lower cost sales and marketing products.

On December 22, 2017, tax legislation was enacted which included lowering the U.S. corporate income tax rate to 21% effective in 2018. We remeasured certain deferred tax assets and liabilities based on the tax rates at which they are expected to reverse in the future, which is generally 21%. As we have a full valuation allowance on US deferred assets, the allowance was adjusted accordingly based on the remeasured deferred tax asset and liability position. As a result, the legislation had a limited impact on our income tax benefit (expense).

In preparing our financial statements, we make estimates, assumptions and judgments that can have a significant impact on our reported revenues, results of operations and net income or loss, as well as on the value of certain assets and liabilities on our balance sheet during and as of the reporting periods. These estimates, assumptions and judgments are necessary because future events and their effects on our results and the value of our assets cannot be determined with certainty, and are made based on our historical experience and on other assumptions that we believe to be reasonable under the circumstances. These estimates may change as new events occur or additional information is obtained, and we may periodically be faced with uncertainties, the outcomes of which are not within our control and may not be known for a prolonged period of time. Because the use of estimates is inherent in the financial reporting process, actual results could differ from those estimates. Revenue Recognition We primarily generate revenue from multiple element arrangements, which typically include subscriptions to our online software solution and on-boarding and training services. Our customers do not have the right to take possession of the online software solution. Revenue from subscriptions, including additional fees for items such as incremental contacts, is recognized ratably over the subscription period beginning on the date the subscription is made available to customers. Substantially all subscription contracts are one year or less. We recognize revenue from on-boarding and training services as the services are provided. Amounts billed that have not yet met the applicable revenue recognition criteria are recorded as deferred revenue. As part of accounting for multiple element arrangements, we must assess if each component has value on a standalone basis and should be treated as a separate unit of accounting. There is an in-depth process that we undergo to determine the standalone value for each component where we determine if an individual component could be sold by itself or if the component is sold by other third parties. If the component has standalone value upon delivery, we account for each component separately. Subscription services have standalone value as they are often sold separate from all other services. On-boarding and training services also have standalone value as they are sold separately by us and by third parties. We allocate total arrangement fees to each element in a multiple element arrangement based on the relative selling price hierarchy of each element. We establish vendor-specific objective evidence of fair value, or VSOE, the most reliable level of allocating standalone value, for our subscription on-boarding and training services when there are a meaningful number of stand-alone transactions in a relevant period and a significant number of those stand-alone transactions have consistent pricing. We note that third party evidence, or TPE, the second most reliable level of allocating standalone value, is not available for determining the standalone value for any of our services because the pricing for any similar third party subscription or on-boarding and training services is inconsistent. Therefore, when we cannot establish VSOE, we rely on best estimate of selling price, or BESP, to allocate value to the various components of our arrangements. To determine VSOE, we consider the median stand-alone sales prices of each type of subscription, on-boarding and training services. We then establish a reasonable range around the stand-alone median pricing, typically plus or minus 20% of the median stand-alone selling price. To determine BESP, we consider the average actual sales price of each type of subscription and on-boarding and training services. We then establish a reasonable range around the average pricing, typically plus or minus 20% of the average selling price. For any transactions where a deliverable falls outside of either the VSOE or BESP 20% range, we reallocate arrangement consideration amongst the deliverables using their respective median or average selling prices. We pay our Partners a commission on the subscription sales price for sales to customers. The classification of the commission paid on our consolidated statements of operations depends on who is purchasing our subscription. In instances where the customer is purchasing the subscription, we are the primary obligor and record the commission paid to the Partner as sales and marketing expense. When the Partner purchases the subscription directly from us, we net the consideration paid to the Partner against the associated revenue we recognize, as in these instances our customer is the Partner and our remaining obligations are to the Partner. We also do not believe we receive a tangible benefit from the payment back to the Partner. Capitalized Software Development Costs Software development costs consist of certain payroll and stock compensation costs incurred to develop functionality for our software and sales and billing platforms, as well as certain upgrades and enhancements that are expected to result in enhanced functionality. We capitalize certain software development costs for new offerings as well as upgrades to our existing software platforms. We amortize these development costs over the estimated useful life of two to five years on a straight-line basis. We believe there are two key estimates within the capitalized software balance, which are the determination of the useful life of the software and the determination of the amounts to be capitalized. 52 We determined that a two to five year life is appropriate for our internal-use software based on our best estimate of the useful life of the internally developed software after considering factors such as continuous developments in the technology, obsolescence and anticipated life of the service offering before significant upgrades. Based on our prior experience, internally generated software will general ly remain in use for a minimum of two to five years before being significantly replaced or modified to keep up with evolving customer and company needs. While we do not anticipate any significant changes to this two to five year estimate, a change in this estimate could produce a material impact on our financial statements. For example, if we received information that indicated the useful life of all internally developed software was one year rather than two, our capitalized software balance would decrease by approximately 50% and our amortization expense would increase by 50% in the year of adoption of the change in estimate. We determine the amount of internal software costs to be capitalized based on the amount of time spent by our developers on projects. Costs associated with building or significantly enhancing our software and sales and billing platforms are capitalized, while costs associated with planning new developments and maintaining our software and sales and billing platforms are expensed as incurred. There is judgment involved in estimating the stage of development as well as estimating time allocated to a particular project. A significant change in the time spent on each project could have a material impact on the amount capitalized and related amortization expense in subsequent periods. Stock-Based Compensation We recognize compensation expense for option awards based on the fair value of the award and on a straight-line basis over the vesting period of the award based on the estimated portion of the award that is expected to vest. Inherent in the valuation and recording of stock-based compensation for option awards, there are several estimates that we make, including in regard to valuation and expense that will be incurred. We use the Black-Scholes option pricing model to measure the fair value of our option awards when they are granted. For stock options and RSUs granted subsequent to our IPO, our board of directors determined the fair value based on the closing price of our common stock as reported on the New York Stock Exchange on the date of grant. We used the daily historical volatility of companies we consider to be our peers. To determine our peer companies, we used the following criteria: software or software-as-a-service companies; similar histories and relatively comparable financial leverage; sufficient public company trading history; and in similar businesses and geographical markets. We used the peers’ stock price volatility over the expected life of our granted options to calculate the expected volatility. The expected term of employee option awards is determined using the average midpoint between vesting and the contractual term for outstanding awards, or the simplified method, because we do not yet have a sufficient history of option exercises. We consider this appropriate as we plan to see changes to our equity structure in the future and there is no other method that would be more indicative of exercise activity. The risk- free interest rate is based on the rate on U.S. Treasury securities with maturities consistent with the estimated expected term of the awards. We have not paid dividends and do not anticipate paying a cash dividend in the foreseeable future and, accordingly, use an expected dividend yield of zero. The following table summarizes the assumptions, other than fair value of our common stock, relating to our stock options granted in the years ended December 31, 2017, 2016, and 2015: Dividend yield Expected volatility (%) Risk-free interest rate (%) Expected term (years) 2017 Year Ended December 31, 2016 — — 39.4 - 43.7 1.74 - 2.09 5.18 - 6.21 38.0 - 41.0 1.38 - 1.41 5.08 - 6.21 2015 — 43.0 - 51.6 1.36 - 1.53 6.18 - 6.22 We will continue to use judgment in evaluating the expected volatility and expected term utilized in our stock-based compensation expense calculations on a prospective basis. As we continue to accumulate additional data related to our common stock, we may refine our estimates of expected volatility and expected term, which could materially impact our future stock-based compensation expense. Goodwill Impairment Goodwill represents the excess of the cost of an acquired entity over the net fair value of the identifiable assets acquired and liabilities assumed. Goodwill is not amortized, but rather is assessed for impairment at least annually. We performed our annual impairment assessment on November 30, 2017. We operate under one reporting unit and as a result, evaluate goodwill impairment based on our fair value as a whole. 53 To determine the number of operating segments and reporting units that are present, we analy zed whether there is any customer, product or geographic information that drives the chief operating decision makers (our chief executive and operating officers) decisions on how to allocate resources and whether any segment management exists. Management h as concluded that operating decisions are made at the consolidated company level and there is no segment management in place that reviews results of operations with the chief operating decision maker. In assessing goodwill for impairment, an entity has the option to assess qualitative factors to determine whether events or circumstances indicate that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If, after assessing the totality of events or circumstances, it is more likely than not that the fair value of the reporting unit is greater than its carrying value, then performing the two-step impairment test is unnecessary. An entity can choose not to perform a qualitative assessment for any of its reporting units, and proceed directly to the use of the two-step impairment test. When assessing goodwill for impairment for the year ended December 31, 2017, we decided to use the two-step quantitative analysis. We determined our enterprise value at the measurement date by using our market capitalization. Based on the results of our most recent annual assessment performed on November 30, 2017, we concluded that the fair value of our reporting unit significantly exceeded its carrying amount and there was no impairment of goodwill. Strategic Investments We hold strategic investments consisting of non-controlling equity investments in privately held companies. These investments without readily determinable fair values for which the Company does not have the ability to exercise significant influence are accounted for using the cost method of accounting. Under the cost method of accounting, the non-marketable securities are carried at cost and are adjusted only for other-than-temporary impairments, certain distributions and additional investments. Fair value is not estimated for non-marketable equity securities if there are no identified events or changes in circumstances that may have an effect on the fair value of the investment. Contractual Obligations and Commitments Contractual obligations are cash that we are obligated to pay as part of certain contracts that we have entered during our course a business. Certain of our leases contain optional termination dates. The table below only includes payments up to the optional termination date. If we were to extended leases beyond the optional termination date the future commitments would increase by approximately $31.6 million. Below is a table that shows the projected outlays as of December 31, 2017: Capital lease obligations Operating leases obligations Vendor commitments Total Letters of Credit Total Less than 1 Year Payments due in: 1-3 Years (in thousands) 3-5 Years More than 5 Years $ $ 1,057 $ 201,900 31,244 234,201 $ 745 $ 19,345 16,327 36,417 $ 312 $ 39,749 12,957 53,018 $ — $ 43,163 1,307 44,470 $ — 99,643 653 100,296 As of December 31, 2017, we had a total of $4.8 million in letters of credit outstanding substantially in favor of certain landlords for office space. These irrevocable letters of credit, which are not included in the table of contractual obligations above, are unsecured and are expected to remain in effect, in some cases, until 2027. Off Balance Sheet Arrangements We have no material off-balance sheet arrangements at December 31, 2017 or 2016 exclusive of items described above and indemnifications of officers, directors and employees for certain events or occurrences while the officer, director or employee is, or was, serving at our request in such capacity. Recent Accounting Pronouncements For information on recent accounting pronouncements, see Recent Accounting Pronouncements in the notes to the consolidated financial statements appearing elsewhere in this Annual Report on Form 10-K. 54 ITEM 7A. Qualitative and Quantitative Disclosures About Market Risk Foreign Currency Exchange Risk We have foreign currency risks related to our revenue and operating expenses denominated in currencies other than the U.S. dollar, primarily the Euro, British Pound Sterling, Australian dollar, Singaporean dollar, and Japanese Yen. Decreases in the relative value of the U.S. dollar to other currencies may negatively affect our revenue and other operating results as expressed in U.S. dollars. We have experienced and will continue to experience fluctuations in our net loss as a result of transaction gains or losses related to revaluing certain current asset and current liability balances that are denominated in currencies other than the functional currency of the entities in which they are recorded. We recognized immaterial amounts of foreign currency gains and losses in each of the periods presented. We have not engaged in the hedging of our foreign currency transactions to date, we are evaluating the costs and benefits of initiating such a program and may in the future hedge selected significant transactions denominated in currencies other than the U.S. dollar as we expand our international operation and our risk grows. Interest Rate Sensitivity Our portfolio of cash and cash equivalents and short- and long-term investments is maintained in a variety of securities, including government agency obligations, corporate bonds and money market funds. Investments are classified as available-for-sale securities and carried at their fair market value with cumulative unrealized gains or losses recorded as a component of accumulated other comprehensive loss within stockholders' equity. A sharp rise in interest rates could have an adverse impact on the fair market value of certain securities in our portfolio. We do not currently hedge our interest rate exposure and do not enter into financial instruments for trading or speculative purposes. Inflation Risk We do not believe that inflation has had a material effect on our business. However, if our costs, in particular personnel, sales and marketing and hosting costs, were to become subject to significant inflationary pressures, we may not be able to fully offset such higher costs through price increases. Our inability or failure to do so could harm our business, operating results and financial condition. Market Risk and Market Interest Risk In May 2017, we issued $400 million aggregate principal amount of 0.25% convertible senior notes due 2022. The fair value of our convertible senior notes is subject to interest rate risk, market risk and other factors due to the convertible feature. The fair value of the convertible senior notes will generally increase as our common stock price increases and will generally decrease as our common stock price declines in value. The interest and market value changes affect the fair value of our convertible senior notes but do not impact our financial position, cash flows or results of operations due to the fixed nature of the debt obligation. Generally, the fair values of 2022 Notes will increase as interest rates fall and decrease as interest rates rise. Additionally, we carry the convertible senior notes at face value less unamortized discount on our balance sheet, and we present the fair value for required disclosure purposes only. The table below provides a sensitivity analysis of hypothetical 10% changes of our stock price as of December 31, 2017 and the estimated impact on the fair value of the 2022 Notes. The selected scenarios are not predictions of future events, but rather are intended to illustrate the effect such event may have on the fair value of the 2022 Notes.

Opinions on the Financial Statements and Internal Control over Financial Reporting We have audited the accompanying consolidated balance sheets of HubSpot, Inc. and its subsidiaries (“the Company”) as of December 31, 2017 and 2016, and the related consolidated statements of operations, comprehensive loss, stockholders’ equity, and cash flows for each of the two years in the period ended December 31, 2017, including the related notes (collectively referred to as the “consolidated financial statements”). We also have audited the Company's internal control over financial reporting as of December 31, 2017, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2017 and 2016, and the results of its operations and its cash flows for each of the two years in the period ended December 31, 2017 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2017, based on criteria established in Internal Control - Integrated Framework (2013) issued by the COSO. Basis for Opinions The Company's management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting , included in Management's Report on Internal Control over Financial Reporting appearing under Item 9A . Our responsibility is to express opinions on the Company’s consolidated financial statements and on the Company's internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) ("PCAOB") and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audits i n accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions. Definition and Limitations of Internal Control over Financial Reporting A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. /s/ PricewaterhouseCoopers LLP Boston, Massachusetts February 13, 2018 We have served as the Company’s auditor since 2016 . 57 REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM To the Board of Directors and Stockholders of HubSpot, Inc.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 1. Organization and Operations HubSpot, Inc. (the “Company”), was formed as a limited liability company in Delaware on April 4, 2005. The Company converted to a Delaware corporation on June 7, 2007. The Company provides a cloud-based inbound marketing and sales platform which features integrated applications to help businesses attract visitors to their websites, convert visitors into leads, close leads into customers and delight customers so they become promoters of those businesses. These integrated applications include social media, search engine optimization, blogging, website content management, marketing automation, email, sales productivity, CRM, analytics, and reporting. 2. Summary of Significant Accounting Policies Basis of Presentation —The consolidated financial statements have been prepared in U.S. dollars, in accordance with accounting principles generally accepted in the United States of America (“GAAP”). The accompanying consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All intercompany transactions have been eliminated in consolidation. Use of Estimates —The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. Operating Segments —The Company operates as one operating segment. Operating segments are defined as components of an enterprise for which separate financial information is regularly evaluated by the chief operating decision makers (“CODMs”), which are the Company’s chief executive officer and chief operating officer, in deciding how to allocate resources and assess performance. The Company’s CODMs evaluate the Company’s financial information and resources and assess the performance of these resources on a consolidated basis. Since the Company operates in one operating segment, all required financial segment information can be found in the consolidated financial statements. Loss Per Share — Basic net loss per share is computed by dividing net loss by the weighted average number of common shares outstanding for the period. Diluted net loss per share is computed by giving effect to all potential dilutive common stock equivalents outstanding for the period. For purposes of this calculation, options to purchase common stock, restricted stock units (“RSUs”), Employee Stock Purchase Plan (“ESPP”), and the Conversion Option of the 2022 Notes (Note 7) are considered to be potential common stock equivalents. A reconciliation of the denominator used in the calculation of basic and diluted loss per share is as follows: Net loss $ Weighted-average common shares outstanding—basic Dilutive effect of share equivalents resulting from stock options, RSUs, ESPP and the Conversion Option of the 2022 Notes Weighted-average common shares outstanding-diluted Net loss per common share, basic and diluted $ (1.08) $ (1.29) $ 64 2017 Year Ended December 31, 2016 (in thousands, except per share amounts) (39,714) $ (45,562) $ 2015 36,827 35,197 — 36,827 — 35,197 (46,053) 33,222 — 33,222 (1.39) Additionally, since the Company incurred net losses for each of the periods presented, diluted net loss per share is the same as basic net loss per share. The Company’s outstanding stock options, RSUs, ESPP, and Conversion Option of the 2022 Notes were not included in the calculation of diluted net loss per share as the effect would be anti-dilutive. The following table contains all potentia lly dilutive common stock equivalents. Options to purchase common shares RSUs ESPP 2017 Year Ended December 31, 2016 (in thousands) 2015 2,085 2,315 10 2,709 2,264 11 3,331 1,703 — The Company expects to settle the principal amount of the 2022 Notes in cash, and therefore, the Company uses the treasury stock method for calculating any potential dilutive effect of the Conversion Option on diluted net income per share, if applicable. The Conversion Option will have a dilutive impact on net income per share of common stock when the average market price of the Company’s common stock for a given period exceeds the conversion price of the 2022 Notes of $94.77 per share. During the year ended December 31, 2017, the Company's weighted average common stock price was below the conversion price of the 2022 Notes. Cash and Cash Equivalents —The Company considers all highly liquid investments purchased with original maturity of three months or less to be cash equivalents. Cash and cash equivalents consist of cash held in bank deposit accounts and short-term, highly-liquid investments with remaining maturities of three months or less at the date of purchase, consisting of money-market funds. Investments — Investments consist of corporate debt securities, U.S. government agency obligations, and U.S. Treasury securities. Securities having remaining maturities of more than three months at the date of purchase and less than one year from the date of the balance sheets are classified as short-term, and those with maturities of more than one year from the date of the balance sheet are classified as long-term in the consolidated balance sheets. The Company classifies its debt investments with readily determinable market values as available-for-sale. These investments are classified as investments on the consolidated balance sheets and are carried at fair market value, with unrealized gains and losses considered to be temporary in nature reported as accumulated other comprehensive loss, a separate component of stockholders’ equity. The Company reviews all investments for reductions in fair value that are other-than-temporary. When such reductions occur, the cost of the investment is adjusted to fair value through recording a loss on investments in the consolidated statements of operations. Gains and losses on investments are calculated on the basis of specific identification. Investments are considered to be impaired when a decline in fair value below cost basis is determined to be other-than-temporary. The Company periodically evaluates whether a decline in fair value below cost basis is other-than-temporary by considering available evidence regarding these investments including, among other factors: the duration of the period that, and extent to which, the fair value is less than cost basis; the financial health of, and business outlook for the issuer, including industry and sector performance and operational and financing cash flow factors; overall market conditions and trends and the Company’s intent and ability to retain its investment in the security for a period of time sufficient to allow for an anticipated recovery in market value. Once a decline in fair value is determined to be other-than-temporary, a write-down is recorded and a new cost basis in the security is established. Strategic investments — Strategic investments consist of non-controlling equity investments in privately held companies. These investments without readily determinable fair values for which the Company does not have the ability to exercise significant influence are accounted for using the cost method of accounting. Under the cost method of accounting, the non-marketable securities are carried at cost and are adjusted only for other-than-temporary impairments, certain distributions and additional investments. Accounts Receivable and Allowance for Doubtful Accounts —Accounts receivable are carried at the original invoiced amount less an allowance for doubtful accounts based on the probability of future collection. When management becomes aware of circumstances that may decrease the likelihood of collection to a point where a receivable is no longer probable of being collected, it records an allowance against amounts due, which reduces the receivable to the amount that management reasonably believes will be collected. For all other customers, management determines the adequacy of the allowance based on historical loss patterns, the number of days that billings are past due and an evaluation of the potential risk of loss associated with specific accounts. To date, losses resulting from uncollected receivables have not exceeded management’s expectations. 65 The following is a roll forward of the Company’s allowance for doubtful accounts (in thousands): Allowance for doubtful accounts Year ended December 31, 2017 Year ended December 31, 2016 Year ended December 31, 2015 (1) Deductions include actual accounts written-off, net of recoveries. Balance Beginning of Period Charged to Statement of Operations Deductions (1) Balance at End of Period $ $ $ 617 $ 371 $ 218 $ 3,353 $ 2,517 $ 1,367 $ (3,332) $ (2,271) $ (1,214) $ 638 617 371 Restricted Cash —The Company had restricted cash of $5.1 million at December 31, 2017 and $483 thousand at December 31, 2016 related to leased facilities. Property and Equipment —Property and equipment are stated at cost and depreciated using the straight-line method over the estimated useful lives of the related assets. Expenditures for maintenance and repairs are charged to expense as incurred, whereas major betterments are capitalized as additions to leasehold improvements. Depreciation is recorded over the following estimated useful lives: Employee related computer equipment Computer equipment and purchased software Office equipment Furniture and fixtures Internal use software Leasehold improvements Estimated Useful Life 2 – 3 years 3 years 5 years 5 years 5 years Lesser of lease term or useful life Internal use software The Company capitalizes certain payroll and stock compensation costs incurred to develop functionality for certain of the Company’s internally built software platforms. The costs incurred during the preliminary stages of development are expensed as incurred. Once a piece of incremental functionality has reached the development stage certain internal costs are capitalized until the functionality is ready for its intended use. Internal use software is included within property and equipment on the balance sheet. The costs are generally amortized on a straight-line basis over an estimated useful life of approximately five years. Asset Retirement Obligations — The Company recognizes Assets Retirement Obligations (“AROs”) for any significant lease restoration obligation, if required by a lease agreement. The fair values of these AROs are recorded on a discounted basis, at the time the obligation is incurred, and accreted over time for the change in present value. Additionally, the Company capitalizes asset retirement costs by increasing the carrying amount of the related long-lived assets and depreciating these assets over their remaining useful life. The changes in these obligations during the year ending December 31, 2017 and December 31, 2016 are as follows: Beginning balance Additions Accretion Settlements Ending balance Year Ended December 31, 2017 2016 (in thousands) 591 $ 580 46 (26) 1,191 $ — 561 30 — 591 $ $ Impairment of Long-Lived Assets —Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable or that the useful lives of those assets are no longer appropriate. Management considers the following potential indicators of impairment of its long-lived assets (asset group): a substantial decrease in the Company’s stock price, a significant adverse change in the extent or manner in which a long-lived asset (asset group) is being used, a significant adverse change in legal factors or in the business climate that could affect the value of the 66 long-lived asset (asset group), an accumulation of costs significantly in excess of the amount originally expected for the acquisition or construction of a lon g-lived asset (asset group), and a current expectation that, more likely than not, a long lived asset (asset group) will be sold or otherwise disposed of significantly before the end of its previously estimated useful life. When such events occur, the Comp any compares the carrying amounts of the assets to their undiscounted expected future cash flows. If this comparison indicates that there may be an impairment, the amount of the impairment is calculated as the difference between the carrying value and fair value. For the years presented, the Company did not recognize an impairment charge. Intangible Assets — Intangible assets consist acquired technology and intellectual property. We record acquired intangible assets at fair value on the date of acquisition. and amortize such assets using the straight-line method over the expected useful life of the asset. The estimated useful life of acquired technology and intellectual property is two to three years. The Company evaluates the useful lives of these assets on an annual basis and tests for impairment whenever events or changes in circumstances occur that could impact the recoverability of these assets. If the estimate of an intangible asset’s remaining useful life is changed, we amortize the remaining carrying value of the intangible asset prospectively over the revised remaining useful life. Goodwill —Goodwill represents the excess of cost over the fair value of the net tangible and identifiable intangible assets acquired in a business combination. The Company has no other intangible assets with indefinite useful lives. Goodwill is not subject to amortization, but is monitored annually for impairment or more frequently if there are indicators of impairment. Management considers the following potential indicators of impairment: significant underperformance relative to historical or projected future operating results, significant changes in the Company’s use of acquired assets or the strategy of the Company’s overall business, significant negative industry or economic trends and a significant decline in the Company’s stock price for a sustained period. The Company performs its annual impairment test on November 30. Currently, the Company’s goodwill is evaluated at the entity level as it is determined there is only one reporting unit. The Company performs a two-step impairment test. In the first step, the fair value of each reporting unit is compared to its carrying amount. If the fair value exceeds the carrying value of the net assets assigned, goodwill is not considered impaired and the second step is not required. If the carrying value exceeds the fair value, then the second step of the impairment test is performed in order to determine the implied fair value of the reporting unit’s goodwill. If the carrying value of the goodwill exceeds the fair value, then an impairment charge is recorded. On November 30, 2017, the fair value of the Company’s single reporting unit exceeded its carrying amount. Because the fair value of the Company’s single reporting unit was in excess of its carrying value and there were no indicators that the Company’s goodwill had become impaired since that date, there was no impairment as of November 30, 2017 or December 31, 2017. For the years ended December 31, 2017, 2016 and 2015, the Company did not recognize an impairment charge. Advertising Expense —The Company expenses advertising as incurred, which is included in sales and marketing expense in the accompanying consolidated statements of operations. The Company incurred $5.5 million of advertising expense in 2017, $4.2 million in 2016, and $4.9 million in 2015. Revenue Recognition —The Company primarily generates revenue from multiple-element arrangements, which typically include subscriptions to its online software solution and professional services which includes on-boarding and training services. The Company’s customers do not have the right to take possession of the online software solution. The Company recognizes revenue when all of the following have occurred: • • • • persuasive evidence of an arrangement with the customer exists; service has been or is being provided; the fees are fixed or determinable; and collectability of the fees is reasonably assured. The Company’s arrangements do not contain general rights of return. In order to treat elements in a multiple-element arrangement as separate units of accounting, the delivered elements must have standalone value and delivery of the undelivered element is probable and within control of the Company. The Company has determined that subscriptions for its online software solution have standalone value because, once a customer launches its initial site, the online software solution is fully functional and does not require any additional development, modification, or customization. Professional services consists primarily of on-boarding and web-based and in-person training, are not required to use the online software solution, and are determined to have stand-alone value from the related subscription services because they are sold separately by the Company and third parties. 67 When multiple-element arrangements are separated into different units of accounting, the arrangement consideration is allocated to the identified separate units based on a relative selling price hierarchy. The estimated fair valu e of each element is determined based upon the following hierarchy: (1) vendor specific objective evidence (“VSOE”) of fair value, (2) third party evidence of selling price (“TPE”), or (3) the Company’s best estimate of selling price (“BESP”). There is not an available measure of TPE of selling price and, as such, arrangement consideration is allocated amongst multiple deliverable arrangements using VSOE, if VSOE can be established, and BESP if VSOE cannot be established. The Company establishes VSOE and BESP for each deliverable primarily considering the median or average of actual sales prices (stand-alone sales prices for VSOE) of each type of subscription and other professional services sold. The Company considers each type of subscription and service as well as pricing and geographic information when establishing VSOE and BESP. Arrangement consideration is allocated such that the revenue recognized does not exceed the fee subject to refund. Revenue from subscriptions is recognized ratably over the subscription period beginning on the date the Company’s subscription is made available to customers. Substantially all subscription contracts are one year or less. The Company recognizes revenue from on-boarding and training services as the services are provided. The Company pays its marketing and sales agency partners (“Partners”) a commission of the subscription sales price for sales to customers. The classification of the commission paid on the Company’s consolidated statements of operations depends on who is purchasing its subscription. In instances where the customer is purchasing the subscription, the Company is the primary obligor and records the commission paid to the Partners as sales and marketing expense. When the Partner purchases the subscription directly from the Company, the Company nets the consideration paid to the Partner against the associated revenue it recognizes, as in these instances the Company’s customer is the Partner and the Company’s remaining obligations are to the Partner. The Company does not believe that it receives a tangible benefit from the payment back to the Partner. Sales taxes collected from customers and remitted to government authorities are excluded from revenue. Amounts that have been invoiced are recorded in accounts receivable and deferred revenue or revenue, depending on whether the revenue recognition criteria have been met. Deferred revenue represents amounts billed for which revenue has not yet been recognized. Deferred revenue that will be recognized during the succeeding 12-month period is recorded as current deferred revenue and the remaining portion is recorded as long-term deferred revenue. Concentrations of Credit Risk and Significant Customers —Financial instruments that potentially expose the Company to concentrations of credit risk consist primarily of cash, investments and accounts receivable. A significant portion of the Company’s cash and cash equivalents is held at four financial institutions that management believes to be of high credit quality. Although the Company deposits it cash and cash equivalents with multiple financial institutions, its deposits exceed federally insured limits. The Company’s investments consist of highly rated corporate debt securities and U.S. government agency obligations, and U.S. Treasury securities . The Company limits the amount of investments in any single issuer. The Company believes that, as of December 31, 2017, its concentration of credit risk related to investments was not significant. The Company has no significant off-balance sheet risk such as foreign exchange contracts, option contracts, or other hedging arrangements. The Company generally does not require collateral from its customers and generally requires payment 30 days from the invoice date. The Company maintains an allowance for doubtful accounts based on its assessment of the collectability of accounts receivable. Credit risk arising from accounts receivable is mitigated as a result of transacting with a large number of geographically dispersed customers spread across various industries. At December 31, 2017 and 2016 there were no customers that represented more than 10% of the net accounts receivable balance. There were no customers that individually exceeded 10% of the Company’s revenue in any of the periods presented. Foreign Currency —The functional currency of the Company’s foreign subsidiaries is the local currency. Assets and liabilities denominated in a foreign currency are translated into U.S. dollars at the exchange rates in effect at the balance sheet dates; with the resulting translation adjustments directly recorded to a separate component of accumulated other comprehensive loss. Income and expense accounts are translated at the weighted-average exchange rates during the period. Foreign currency transaction gains and losses are recorded in other income (expense). Research and Development —Research and development expenses include payroll, employee benefits and other expenses associated with product development. 68 Capitalized Software Development Costs —Certain payroll and stock compensation costs incurred to develop functionality for the Company’s software and internally built software platforms, as well as certain upgrades and enhancemen ts that are expected to result in increased functionality are capitalized. The costs incurred in the preliminary stages of development are expensed as incurred. Once an application has reached the development stage, certain internal costs are capitalized u ntil the software is substantially complete and ready for its intended use. Capitalized software development costs are amortized on a straight-line basis over their estimated useful life of two to five years. Management evaluates the useful lives of these assets on a quarterly basis and tests for impairment whenever events or changes in circumstances occur that could impact the recoverability of these assets. Capitalized software development costs, exclusive of those costs recorded within property and equipment, consisted of the following: Gross capitalized software development costs Accumulated amortization Capitalized software development costs, net December 31, 2017 December 31, 2016 $ $ (in thousands) 33,360 (24,600) 8,760 $ $ 25,152 (18,629) 6,523 The Company capitalized software development costs, exclusive of costs recorded within property and equipment, of $8.2 million in 2017, $6.4 million in 2016, and $4.5 million in 2015. Stock-based compensation costs included in capitalized software were $1.6 million in 2017, $1.2 million in 2016, and $492 thousand in 2015. Amortization of capitalized software development costs, exclusive of costs recorded within property and equipment, was $6.3 million in 2017, $5.1 million in 2016, and $4.6 million in 2015. Amortization expense is included in cost of revenue in the consolidated statements of operations. Income Taxes —Deferred tax assets and liabilities are recognized for the differences between the financial statement carrying amounts and the tax bases of existing assets and liabilities using tax rates expected to be in effect in the years in which the differences are expected to reverse. Deferred tax assets are reduced by a valuation allowance if it is more likely than not that some portion or all of the deferred tax assets will not be realized. Accounting for uncertainty in income taxes recognized in the financial statements is in accordance with accounting authoritative guidance, which prescribes a two-step process to determine the amount of tax benefit to be recognized. First, the tax position must be evaluated to determine the likelihood that it will be sustained upon external examination. If the tax position is deemed “more-likely-than-not” to be sustained, the tax position is then assessed to determine the amount of benefit to recognize in the financial statements. The amount of the benefit that may be recognized is the largest amount that has a greater than 50 percent likelihood of being realized upon ultimate settlement. Undistributed foreign earnings of approximately $6.9 million have been taxed in 2017 due to a one-time transition tax on previously undistributed foreign earnings. For any future foreign earnings, the Company will generally be free of additional U.S. federal tax consequences due to a dividends received deduction implemented as part of the move to a territorial tax system for foreign subsidiary earnings. Stock-Based Compensation —The Company accounts for all stock options and awards granted to employees and nonemployees using a fair value method. Stock-based compensation is recognized as an expense and is measured at the fair value of the award. The measurement date for employee awards is generally the date of the grant. The measurement date for nonemployee awards is generally the date the awards vest. Stock-based compensation costs are recognized as expense over the requisite service period, which is generally the vesting period for awards, on a straight-line basis for awards with only a service condition, and using the graded-method for awards with both a performance and service that were granted prior to our IPO, and on a straight-line basis for the awards that were granted following our IPO, which only have service conditions. Recent Accounting Pronouncements — Recent accounting standards not included below are not expected to have a material impact on our consolidated financial position and results of operations. The Company adopted updated guidance related to certain aspects of share-based payments to employees. The guidance requires the recognition of the income tax effects of awards in the income statement when the awards vest or are settled, thus eliminating additional paid-in capital pools. As a result of the adoption, we recorded an increase to deferred tax assets with a corresponding increase to the valuation allowance of $30.4 million to recognize net operating loss carryforwards attributable to excess tax benefits on stock compensation that had not been previously recognized as additional paid-in capital. In addition, the Company changed its policy election to account for forfeitures as they occur rather than on an estimated basis. The change in the policy election related to forfeitures resulted in the Company reclassifying $452 thousand from additional paid-in capital to accumulative deficit for the net cumulative-effect adjustment in stock compensation expense related to prior periods. 69 In January 2017, the Financial Accounting Standards Board (“FASB”) issued guidance , which clarifies the definition of a business to assist entities with evaluating whether transactions should be accounted for as acquisitions or disposals of assets or businesses. The standard introduces a screen for determining when assets acquired are n ot a business and clarifies that a business must include, at a minimum, an input and a substantive process that contribute to an output to be considered a business. This standard is effective for fiscal years beginning after December 15, 2017, including in terim periods within that reporting period, and early adoption is permitted. The Company adopted this standard in the third quarter of 2017 and the adoption of this standard did not have a material impact on the consolidated financial statements. In January 2017, the FASB issued guidance simplifying the accounting for goodwill impairment by removing Step 2 of the goodwill impairment test. Under current guidance, Step 2 of the goodwill impairment test requires entities to calculate the implied fair value of goodwill in the same manner as the amount of goodwill recognized in a business combination by assigning the fair value of a reporting unit to all of the assets and liabilities of the reporting unit. The carrying value in excess of the implied fair value is recognized as goodwill impairment. Under the new standard, goodwill impairment is recognized based on Step 1 of the current guidance, which calculates the carrying value in excess of the reporting unit’s fair value. The new standard is effective beginning in January 2020, with early adoption permitted. We do not believe the adoption of this guidance will have a material impact on our consolidated financial statements. In November 2016, the FASB issued guidance related to the presentation of restricted cash within the statement of cash flows. The guidance requires entities to show the changes in cash, cash equivalents, and restricted cash in the statement of cash flows. Entities will no longer present transfers between cash and cash equivalents and restricted cash in the statement of cash flows. As of December 31, 2017, we had $5.1 million in restricted cash. The new standard is effective beginning in the first quarter of 2018, with early adoption permitted. The impact of including restricted cash with cash and cash equivalents when reconciling the beginning-of-year and end-of-year total amounts presented on the consolidated statement of cash flows would increase net cash flows for the year ended December 31, 2017 by approximately $4.6 million. In February 2016, the FASB issued guidance that requires lessees to recognize most leases on their balance sheets but record expenses on their income statements in a manner similar to current accounting. For lessors, the guidance modifies the classification criteria and the accounting for sales-type and direct financing leases. The guidance is effective in 2019 with early adoption permitted. The Company is currently evaluating the impact of this guidance on the consolidated financial statements. In June 2016, the FASB issued guidance that introduces a new methodology for accounting for credit losses on financial instruments, including available- for-sale debt securities. The guidance establishes a new "expected loss model" that requires entities to estimate current expected credit losses on financial instruments by using all practical and relevant information. Any expected credit losses are to be reflected as allowances rather than reductions in the amortized cost of available-for-sale debt securities. This guidance will be effective for the Company on January 1, 2020. The Company is currently evaluating the impact of this guidance on the consolidated financial statements. In May 2014, the FASB issued updated guidance and disclosure requirements for recognizing revenue. The new revenue recognition standard provides a five-step analysis of transactions to determine when and how revenue is recognized. The core principle is that a company should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The standard also provides guidance on the recognition of costs related to obtaining customer contracts. The new standard is effective for the Company for its annual reporting periods beginning January 1, 2018. The Company will adopt the standard on January 1, 2018, using the modified retrospective method, which will result in a cumulative effect adjustment as of the date of adoption. The Company established a team that has assessed the impact of the standard including the timing of revenue recognition and the accounting for deferred commission costs and related balances. The Company has determined that there will be a change to the period over which sales commissions will be amortized to incorporate an estimated customer life and the amortization period over which internally developed new features and increased functionality for our software platform is recorded, in addition to the initial contract period. This will result in a longer amortization period for deferred sales commissions, which will reduce the expense in any one period compared to today. There will also be a change to the scope of capitalized sales commissions based on the definition of incremental costs of obtaining a contract. This will result in a higher capitalized commissions balance upon adoption. In addition, there will be a change in relation to the timing of revenue recognition for certain sales contracts, where free or discounted services are bundled with our subscription offering due primarily to the removal of the current limitation on contingent revenue. This will accelerate revenue recognition on these contracts when these services are provided up front as compared to today. The change in the period over which sales commissions will be amortized will have a material impact to the consolidated financial statements and disclosures. The change in the timing of revenue recognition for certain sales contracts, where free or discounted services are bundled with our subscription offering, will not have a material impact to the consolidated financial statements and disclosures. 70 3. Fair Value of Financial Instruments The Company measures certain financial assets at fair value. Fair value is determined based upon the exit price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants, as determined by either the principal market or the most advantageous market. Inputs used in the valuation techniques to derive fair values are classified based on a three-level hierarchy, as follows: Level 1 — Quoted prices in active markets for identical assets or liabilities. Level 2 — Observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets with insufficient volume or infrequent transactions (less active markets); or model-derived valuations in which all significant inputs are observable or can be derived principally from or corroborated by observable market data for substantially the full term of the assets or liabilities. Level 3 — Unobservable inputs to the valuation methodology that are significant to the measurement of fair value of assets or liabilities. The following table details the fair value measurements within the fair value hierarchy of the Company’s financial assets and liabilities at December 31, 2017 and December 31, 2016: Cash equivalents and investments: Money market funds Commercial paper Corporate bonds U.S. government agency obligations U.S. Treasury securities Restricted cash: Certificates of deposit Total Cash equivalents and investments: Money market funds Commercial paper Corporate bonds U.S. government agency obligations Total December 31, 2017 Level 1 Level 2 Level 3 Total (in thousands) $ 12,845 — — — — — $ 5,867 81,668 3,987 356,535 — 12,845 $ 5,105 453,162 $ — — — — — — — $ $ 12,845 5,867 81,668 3,987 356,535 5,105 466,007 Level 1 Level 2 Level 3 Total December 31, 2016 (in thousands) 32,260 — — — 32,260 $ $ — $ 12,439 66,947 10,980 90,366 $ — — — — — $ $ 32,260 12,439 66,947 10,980 122,626 $ $ $ $ The Company considers all highly liquid investments purchased with a remaining maturity of three months or less to be cash equivalents. The fair value of the Company’s investments in certain money market funds is their face value and such instruments are classified as Level 1 and are included in cash and cash equivalents on the consolidated balance sheets. At December 31, 2017 and December 31, 2016, our Level 2 securities were priced by pricing vendors. These pricing vendors utilize the most recent observable market information in pricing these securities or, if specific prices are not available for these securities, use other observable inputs like market transactions involving identical or comparable securities. As of December 31, 2017, the fair value of the 2022 Notes (Note 7) was $460.0 million. The fair value was determined based on the quoted price of the 2022 Notes in an inactive market on the last trading day of the reporting period and has been classified as Level 2 within the fair value hierarchy. For certain other financial instruments, including accounts receivable, accounts payable, capital leases and other current liabilities, the carrying amounts approximate their fair value due to the relatively short maturity of these balances. Restricted cash is comprised of certificates of deposit related to landlord guarantees for our leased facilities. These restricted cash balances have been excluded from our cash and cash equivalents balance on our consolidated balance sheets. 71 Strategic investments consist of non-controlling equity investments in privately held companies. These investments without readily determinable fair values for which the Company does no t have the ability to exercise significant influence are accounted for using the cost method of accounting. Under the cost method of accounting, the non-marketable securities are carried at cost and are adjusted only for other-than-temporary impairments, c ertain distributions and additional investments. These investments are valued using significant unobservable inputs or data in an inactive market and the valuation requires the Company's judgment due to the absence of market prices and inherent lack of liq uidity. The estimated fair value is based on quantitative and qualitative factors including, but not limited to, subsequent financing activities by the investee and projected discounted cash flows. Fair value is not estimated for non-marketable equity secu rities if there are no identified events or changes in circumstances that may have an effect on the fair value of the investment. The carrying value of the strategic investments was $3.5 million at December 31, 2017 and $0 at December 31, 2016. Strategic i nvestments are included with other assets on the consolidated balance sheets. The following tables summarize the composition of our short- and long-term investments at December 31, 2017 and 2016: Commercial paper Corporate bonds U.S. government agency obligations U.S. Treasury securities Total Commercial paper Corporate bonds U.S. government agency obligations Total Amortized Cost Unrealized Gains Unrealized Losses Aggregate Fair Value December 31, 2017 5,874 $ 81,947 4,000 356,671 448,492 $ (in thousands) — $ — — 8 8 $ (7) $ (279) (13) (144) (443) $ 5,867 81,668 3,987 356,535 448,057 Amortized Cost Unrealized Gains Unrealized Losses Aggregate Fair Value December 31, 2016 12,446 $ 67,126 10,998 90,570 $ (in thousands) — $ — — — $ (7) $ (179) (18) (204) $ 12,439 66,947 10,980 90,366 $ $ $ $ For all of our securities for which the amortized cost basis was greater than the fair value at December 31, 2017 and 2016, the Company has concluded that there is no plan to sell the security nor is it more likely than not that the Company would be required to sell the security before its anticipated recovery. In making the determination as to whether the unrealized loss is other-than-temporary, the Company considered the length of time and extent the investment has been in an unrealized loss position, the financial condition and near-term prospects of the issuers, the issuers’ credit rating and the time to maturity. Contractual Maturities The contractual maturities of short-term and long-term investments held at December 31, 2017 and 2016 are as follows: Due within one year Due after 1 year through 2 years Total December 31, 2017 December 31, 2016 Amortized Cost Basis Aggregate Fair Value Amortized Cost Basis Aggregate Fair Value $ $ 416,932 $ 31,560 448,492 $ (in thousands) 416,663 $ 31,394 448,057 $ $ 54,694 35,876 90,570 $ 54,648 35,718 90,366 72 4. Property and Equipment Property and equipment as of December 31, 2017 and December 31, 2016 consists of the following: Computer equipment & purchased software Employee computer equipment Furniture and fixtures Office equipment Leasehold improvements Equipment under capital lease Internal-use software Construction in progress Total property and equipment Less accumulated depreciation Property and equipment, net December 31. 2017 2016 (in thousands) 4,571 $ 4,260 11,083 2,620 33,446 3,450 2,892 3,198 65,520 (22,226) 43,294 $ 3,237 1,534 8,174 2,326 23,693 2,412 1,301 322 42,999 (12,798) 30,201 $ $ Depreciation and amortization expense was $9.4 million in 2017, $5.9 million in 2016, and $2.7 million in 2015. Accumulated depreciation for equipment under capital lease was $2.4 million as of December 31, 2017 and $1.2 million as of December 31, 2016. The Company capitalized asset retirement costs of $1.1 million at December 31, 2017 and $561 thousand at December 31, 2016 within leasehold improvements on the consolidated balance sheets, and recorded the related liability to other long-term liabilities. These costs represent future lease restoration obligations as required by Company’s leases. 5. Business Acquisition and Purchase of Technology On September 20, 2017, the Company acquired 100% of the equity interests of Motion AI, Inc., a Delaware technology corporation that allows users to scale one-to-one communications. The acquisition strengthens the Company’s position in the one-to-one communication space. Under the terms of the purchase agreement, the Company paid $9.0 million. The excess of the purchase consideration over the fair value of net tangible and identifiable intangible assets and liabilities acquired was recorded as goodwill and is primarily attributable to expanded market opportunities. The goodwill recognized is not deductible for U.S. income tax purposes. The fair values assigned to tangible and identifiable intangible assets acquired and liabilities assumed as part of the business combination were determined based on the replacement costs and present value of expected after-tax cash flows attributable to the business which were derived from management’s estimates and assumptions. The sole intangible asset acquired in the business combination was developed technology and the estimate of fair value of the developed technology was determined using a replacement cost approach and the useful life of the technology was estimated to be two years. The Company will begin amortizing the acquired technology when the technology is placed in use, which is expected to be 2018. The acquired technology will be amortized over its useful life of two year. The amortization expense will be recorded to cost of subscription revenue in the consolidated statements of operations. The preliminary allocation of the purchase price to the estimated fair value of acquired assets and assumed liabilities is $32 thousand of tangible assets, $6.0 million of acquired technology, and $5.2 million of goodwill. As part of the purchase price allocation, the Company recorded a deferred tax benefit of $2.2 million from a partial release of its deferred tax asset valuation allowance. The net deferred tax liability from this acquisition provided a source of additional income to support the realizability of the Company’s pre-existing deferred tax assets and as a result, the Company released a portion of its valuation allowance. Lastly, there was approximately $4.0 million of potential consideration that was not included in the purchase price allocation as it is not associated with pre-combination services. If earned, this will be recorded in the consolidated statement of operations over a period of approximately three years. The Company has included the operating results of the business combination in its consolidated financial statements since the date of the acquisition. The acquisition did not have a material effect on the revenue or earnings in the consolidated income statement for the reporting periods presented. The pro forma results of the Company as if the acquisition had taken place on the first day of 2016 were not materially different from the amounts reflected in the accompanying consolidated financial statements. 73 During the third quarter of 2017 the Company also acquired technology for $400 thousand. The estimated useful life of the acquired technology is two years. 6. Intangible Assets Intangible assets as of December 31, 2017 and 2016 consist of the following: Acquired technology Acquired intellectual property Accumulated amortization Total Weighted Average Remaining Useful Life 19 Months $ — $ December 31, 2017 2016 $ (in thousands) 7,252 80 (1,020) $ 6,312 852 80 (916) 16 The estimated useful life of acquired technology and intellectual property is two to three years. The Company evaluates the useful lives of these assets on an annual basis and tests for impairment whenever events or changes in circumstances occur that could impact the recoverability of these assets. Amortization expense related to intangible assets was $103 thousand in 2017, $84 thousand in 2016, and $96 thousand in 2015. Amortization expense of acquired technology is included in cost of subscription revenue in the consolidated statements of operations. Amortization expense of acquired intellectual property is included in sales and marketing expense in the consolidated statements of operations. Estimated future amortization expense for intangible assets, currently being amortized, as of December 31, 2017 is as follows: Years ended December 31, 2018 2019 Total Amortization Expense (in thousands) 200 112 312 $ The estimated amortization does not include the amortization of the $6.0 million of acquired technology from the acquisition of Motion AI, Inc. as the intangible asset has not been placed into service as of December 31, 2017. The Company expects that the acquired technology will be placed into service during 2018 and will be amortized through 2020. 7. 0.25% Convertible Senior Notes, Convertible Note Hedge and Warrant In May 2017, the Company issued $350 million aggregate principal amount of 0.25% convertible senior notes due June 1, 2022 (the “Maturity Date”) in a private offering and an additional $50 million aggregate principal amount of such notes pursuant to the exercise in full of the over-allotment options of the initial purchasers (the “2022 Notes”). The interest rates are fixed at 0.25% per annum and are payable semi-annually in arrears on June 1 and December 1 of each year, commencing on December 1, 2017. The total net proceeds from the debt offering, after deducting initial purchase discounts and debt issuance costs, were approximately $389.2 million. Each $1,000 principal amount of the 2022 Notes will initially be convertible into 10.5519 shares of the Company’s common stock (the “Conversion Option”), which is equivalent to an initial conversion price of approximately $94.77 per share, subject to adjustment upon the occurrence of specified events. The 2022 Notes will be convertible at the option of the holders at any time prior to the close of business on the business day immediately preceding February 1, 2022, only under the following circumstances: (1) during any calendar quarter commencing after the calendar quarter ending on June 30, 2017, if the last reported sale price of the Company’s common stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price on each applicable trading day; (2) during the five business day period after any five consecutive trading day period (the “Measurement Period”) in which the trading price per $1,000 principal amount of notes for each trading day of the Measurement 74 Period was less than 98% of the product of the last reported sale price of the Company’s common stock and the conversion rate on each such trading day; or (3) upon the occurrence of specified corporate events. On or after February 1, 2022 until the close of business on the second scheduled trading day immediately preceding the Maturity Date, holders may convert their 2022 Notes at any time, regardless of the foregoing circumstances. Upon conversion, the Company will pay or deliver, as the case may be, cash, shares of the Company’s common stock or a combination of cash and shares of the Company’s common s tock, at the Company’s election. If the Company undergoes a fundamental change prior to the maturity date, holders of the notes may require the Company to repurchase for cash all or any portion of their notes at a repurchase price equal to 100% of the pri ncipal amount of the notes to be repurchased, plus accrued and unpaid interest to, but excluding, the fundamental change repurchase date. In addition, if specific corporate events occur prior to the applicable maturity date, the Company will increase the c onversion rate for a holder who elects to convert their notes in connection with such a corporate event in certain circumstances. During the year ended December 31, 2017, the conditions allowing holders of the 2022 Notes to convert have not been met. Th e 2022 Notes are therefore not convertible during the year ended December 31, 2017 and are classified as long-term debt. In accounting for the issuance of the convertible senior notes, the Company separated the 2022 Notes into liability and equity components. The carrying amount of the liability component was calculated by measuring the fair value of a similar debt instrument that does not have an associated convertible feature. The carrying amount of the equity component representing the Conversion Option was $106 million and was determined by deducting the fair value of the liability component from the par value of the 2022 Notes. The equity component is not remeasured as long as it continues to meet the conditions for equity classification. The excess of the principal amount of the liability component over its carrying amount (the "Debt Discount") is amortized to interest expense over the term of the 2022 Notes expense at an effective interest rate of 6.95% over the contractual term of the 2022 Notes. In accounting for the debt issuance costs of $10.8 million related to the 2022 Notes, the Company allocated the total amount incurred to the liability and equity components of the 2022 Notes based on their relative values. Issuance costs attributable to the liability component were $7.9 million and will be amortized to interest expense using the effective interest method over the contractual terms of the 2022 Notes. Issuance costs attributable to the equity component were $2.9 million and are netted with the equity component in stockholders’ equity. The net carrying amount of the liability component of the 2022 Notes is as follows: Principal Unamortized debt discount Unamortized issuance costs Net carrying amount As of December 31, 2017 As of December 31, 2016 $ $ (in thousands) 400,000 $ (94,498) (7,055) 298,447 $ — — — — The net carrying amount of the equity component of the 2022 Notes is as follows: Debt discount for conversion option Issuance costs Net carrying amount $ $ (in thousands) 106,006 (2,854) 103,152 $ — — — As of December 31, 2017 As of December 31, 2016 Interest expense related to the 2022 Notes is as follows: Contractual interest expense Amortization of debt discount Amortization of issuance costs Total interest expense Year Ended December 31, 2017 2016 2015 639 859 11,507 13,005 (in thousands) $ $ — — — — $ $ — — — — $ $ 75 In connection with the offering of the 2022 Notes, the Company entered into convertible note hedge transactions (the “Convertible Note Hedges”) with certain counterparties in which the Company has the option to purchase (subject to adjust ment for certain specified events) a total of approximately 4.2 million shares of the Company’s common stock at a price of approximately $94.77 per share. The Convertible Note Hedges will be settled in cash or shares, or any combination thereof, in accord ance with the settlement method of the 2022 Notes in excess of the par amount, and are expected to settle upon conversion of the 2022 Notes. The total cost of the Convertible Note Hedges was $78.9 million. In addition, the Company sold warrants to certai n bank counterparties whereby the holders of the warrants have the option to purchase initially (subject to adjustment for certain specified events) a total of approximately 4.2 million shares of the Company’s common stock at a price of $115.8 per share. The amount by which the settlement price exceeds the strike price may be settled in shares or cash at the Company’s election. The warrants are expected to settle three business days from each trading day commencing on September 1, 2022 and ending on the 7 9th trading day thereafter. The Company received $58.9 million in cash proceeds, net of issuance costs of $200 thousand, from the sale of these warrants. Taken together, the purchase of the Convertible Note Hedges and the sale of warrants are intended to offset any actual dilution from the conversion of these notes and to effectively increase the overall conversion price from $94.77 to $115.83 per share. As these transactions meet certain accounting criteria, the Convertible Note Hedges and warrants are r ecorded in stockholders’ equity and are not accounted for as derivatives. The net cost of $20 million incurred in connection with the Convertible Note Hedges and warrant transactions was recorded as a reduction to additional paid-in capital on the consolid ated balance sheet. The difference between the Debt Discount and the total cost of the Convertible Note Hedges, and the difference between the calculation of the book and tax allocation of debt issuance costs between the liability and equity components of the 2022 Notes, resulted in a difference between the carrying amount and tax basis of the 2022 Notes. This taxable temporary difference resulted in the Company recognizing a $9.4 million deferred tax liability which was recorded as an adjustment to additional paid-in capital on the consolidated balance sheet. The creation of the deferred tax liability is recognized as a component of equity and represents a source of future taxable income which supports realization of a portion of the income tax benefit associated with the 2017 loss from operations. Therefore, the Company recorded a corresponding income tax benefit in its consolidated statement of operations in 2017. The net equity impact, included in additional paid-in capital, of the above components of the 2022 Notes is as follows: Conversion Option Purchase of Convertible Note Hedges Sales of warrants Issuance costs Deferred tax liability Total $ $ (in thousands) 106,006 (78,920) 59,080 (3,054) (9,399) 73,713 8. Geographic Data As more fully described in the Company’s Summary of Significant Accounting Policies, the Company operates in one operating segment. Revenue and long-lived assets by geographic region, based on physical location of the operations recording the sale or the assets are as follows: Revenues by geographical region: Americas Europe Asia Pacific Total Percentage of revenues generated outside of the Americas 2017 Year Ended December 31, 2016 (In thousands) 2015 $ $ 283,696 70,895 21,021 375,612 $ $ 219,422 41,616 9,929 270,967 $ $ 154,625 23,487 3,831 181,943 24% 19% 15% In 2017, revenue derived from customers outside the United States (international) was approximately 33% of total revenue.

Commitments and Contingencies The Company leases its office facilities under non-cancelable operating leases that expire at various dates through October 2027. Rent expense for non- cancellable operating leases with free rental periods or scheduled rent increases is recognized on a straight-line basis over the terms of the leases. Certain leases contain optional termination dates. The table below only includes payments up to the optional termination date. If the Company were to extended leases beyond the optional termination date the future commitments would increase by approximately $31.6 million. Improvement reimbursements from landlords of $7.3 million are being amortized on a straight-line basis into rent expense over the terms of the leases. The difference between required lease payments and rent expense has been recorded as deferred rent. Rent expense was $18.9 million in 2017, $13.8 million in 2016, and $7.4 million in 2015. Deferred rent was $19.0 million as of December 31, 2017 and $10.2 million as of December 31, 2016. Future minimum payments under all operating and capital lease agreements as of December 31, 2017, are as follows: 2018 2019 2020 2021 2022 Thereafter Total Less: Portion representing interest Capital lease obligation $ $ Operating Capital (in thousands) 19,345 $ 19,752 19,997 21,433 21,729 99,644 201,900 $ 771 290 30 — — — 1,091 (34) 1,057 In January 2018, the Company entered into a new 18 year property lease in Dublin, Ireland, with an option to break the lease after 10 years, for approximately 13,000 square feet of space. The lease commenced in January 2018 and the Company will pay an aggregate of approximately $8.5 million in rent over the initial 10 year lease period. 77 The Company has entered into certain non-cancelable arrangements (“Vendor Commitments”), which require the future purchase of goods or services. Future minimum payments under all Vendor Commitments as of December 31, 2017, are as follows: 2018 2019 2020 2021 2022 Thereafter Total Product related obligations INBOUND event obligations (in thousands) 15,852 10,826 1,500 — — — 28,178 $ 475 316 316 653 653 653 3,066 $ Legal Contingencies From time to time the Company may become involved in legal proceedings or be subject to claims arising in the ordinary course of its business. Although the results of litigation and claims cannot be predicted with certainty, the Company currently believes that the final outcome of these ordinary course matters will not have a material adverse effect on its business, operating results, financial condition or cash flows. Regardless of the outcome, litigation can have an adverse impact on the Company because of defense and settlement costs, diversion of management resources and other factors. 10.

Stockholders’ Equity and Stock-Based Compensation Common Stock Reserved —As of December 31, 2017 and 2016, the Company has authorized 500 million shares of common stock. The number of shares of common stock reserved for the vesting of RSUs, exercise of common stock options, and ESPP are as follows (in thousands): RSUs Common stock options ESPP December 31, 2017 December 31, 2016 2,085 2,315 10 4,410 2,264 2,709 11 4,984 78 Equity Incentive Plan —The Company’s 2007 Equity Incentive Plan (the “2007 Plan”) was terminated in connection with the IPO, and accordingly, no shares are available for issuance under the 2007 Plan. The 2007 Plan will continue to govern outstanding awards granted thereunder, The 2007 Plan provided for the grant of qualified incentive stock options and nonqualified stock options or other awards su ch as RSUs to the Company’s employees, officers, directors and outside consultants. The term of each option is fixed by the Company’s compensation committee and may not exceed 10 years from the date of grant . As of December 31, 2017, 1.7 million options to purchase common stock and 49 thousand RSUs remained outstanding under the 2007 Plan. On September 25, 2014, the Company’s board of directors adopted and the Company’s stockholders approved the 2014 Stock Option and Incentive Plan (the “2014 Plan”). The 2014 Plan became effective upon the closing of the Company’s IPO. The Company initially reserved 1,973,551 shares of its common stock, or the Initial Limit, for the issuance of awards under the 2014 Plan. The 2014 Plan provides that the number of shares reserved and available for issuance under the plan automatically increases each January 1, beginning on January 1, 2015, by 5% of the outstanding number of shares of the Company’s common stock on the immediately preceding December 31 or such lesser number of shares as determined by the compensation committee. This number is subject to adjustment in the event of a stock split, stock dividend or other change in the Company’s capitalization. The term of each option is fixed by the Company’s compensation committee and may not exceed 10 years from the date of grant. As of December 31, 2017, 582 thousand options to purchase common stock and 2.0 million RSUs remained outstanding under the 2014 Plan. Equity Compensation Expense —The Company’s equity compensation expense is comprised of awards of options to purchase common stock, RSUs, and stock issued under the Company’s ESPP. The following two tables show stock compensation expense by award type and where the stock compensation expense is recorded in the Company’s consolidated statements of operations: Options ESPP RSUs Total stock-based compensation Cost of revenue, subscription Cost of revenue, service Research and development Sales and marketing General and administrative Total stock-based compensation 2017 Year Ended December 31, 2016 (in thousands) 2015 4,948 $ 1,233 41,136 47,317 $ 5,202 $ 1,093 26,380 32,675 $ 6,349 1,035 13,924 21,308 2017 2016 (in thousands) 2015 658 $ 2,327 12,816 19,016 12,500 47,317 $ 512 $ 1,640 8,828 13,352 8,343 32,675 $ 341 1,216 6,327 7,658 5,766 21,308 $ $ $ $ Excluded from stock-based compensation expense is $1.6 million of capitalized software development costs in 2017, $1.2 million in 2016, and $492 thousand in 2015. Stock Options —The fair value of employee options is estimated on the date of each grant using the Black-Scholes option-pricing model with the following assumptions: Risk-free interest rate (%) Expected term (years) Volatility (%) Expected dividends 2017 1.74-2.09 5.18-6.21 39.4-43.7 — Year Ended December 31, 2016 1.38 - 1.41 5.08 - 6.21 38.0 - 41.0 — 2015 1.36 - 1.53 6.18 - 6.22 43.0 - 51.6 — The weighted-average grant-date fair value of options granted was $24.56 per share in 2017, $16.97 per share in 2016, and $16.53 per share in 2015. The interest rate was based on the U.S. Treasury bond rate at the date of grant with a maturity approximately equal to the expected term. The expected term of options granted to employees was calculated using the simplified method, which represents the average of the contractual term of the option and the weighted- average vesting period of the option. The expected term of options 79 granted to nonemployees is equal to the remaining contractual term as of t he measurement date. Expected volatility for the Company’s common stock was based on an average of the historical volatility of a peer group of similar public companies. The assumed dividend yield is based upon the Company’s expectation of not paying divid ends in the foreseeable future. Forfeitures of share-based awards prior to vesting results in a reversal of previously recorded stock-compensation expense associated with such forfeited awards Prior to the Company’s IPO, the fair value of the Company’s common stock was determined by the Board of Directors at each award grant date based upon a variety of factors, including the results obtained from independent third-party valuations, the Company’s financial position and historical financial performance, the status of technological developments within the Company’s products, the composition and ability of the engineering and management team, an evaluation of benchmark of the Company’s competition, the climate in the marketplace, the illiquid nature of the common stock, arm’s-length sales of the Company’s capital stock (including redeemable convertible preferred stock), the effect of the rights and preferences of the preferred stockholders and the prospects of a liquidity event, among others. After the Company’s IPO, the fair value of the Company’s common stock is the closing price of the stock on the date of grant. The stock option activity for the year ended December 31, 2017 is as follows: Options (in thousands) Weighted- Average Exercise Price Weighted- Average Remaining Life (in years) Aggregate Intrinsic Value (in thousands) 89,411 6.1 $ Outstanding—January 1, 2017 Granted Exercised Forfeited/expired Outstanding—December 31, 2017 Options vested or expected to vest—December 31, 2017 Options exercisable—December 31, 2017 2,709 $ 180 (543) (31) 2,315 2,315 $ 1,945 $ 13.99 56.67 16.07 24.12 16.69 16.69 11.39 5.3 $ 5.3 $ 4.8 $ 165,974 165,974 149,803 Total unrecognized compensation cost related to the nonvested options was $5.4 million at December 31, 2017. That cost is expected to be recognized over a weighted-average period of 2.2 years as of December 31, 2017. Restricted Stock Units —RSUs vest upon achievement of a service condition and, prior to six months after the Company’s IPO, a performance condition. As soon as practicable following each vesting date, the Company will issue to the holder of the RSUs the number of shares of common stock equal to the aggregate number of RSUs that have vested. Notwithstanding the foregoing, the Company may, in its sole discretion, in lieu of issuing shares of common stock to the holder of the RSUs, pay the holder an amount in cash equal to the fair market value of such shares of common stock. The service condition is a time-based condition met over a period of four years, with 25% met after one year, and then in equal monthly or quarterly installments over the succeeding three years, or over a period of four years, with equal quarterly installments over those four years. The performance condition was met six months following the Company’s IPO. Upon completion of the Company’s IPO the Company began recording stock-based compensation expense based on the grant-date fair value of the RSUs using the accelerated attribution method for RSUs granted prior to its IPO and using the straight-line method for RSUs granted following its IPO. The total stock-based compensation expense expected to be recorded over the remaining life of outstanding RSUs is approximately $102.3 million at December 31, 2017. That cost is expected to be recognized over a weighted-average period of 2.7 years as of December 31, 2017. As of December 31, 2017, there are 2.1 million RSUs expected to vest with an aggregate intrinsic value of $184.1million. The total fair value of RSUs vested was approximately $48.6 million in the year ended December 31, 2017, $24.0 million in the year ended December 31, 2016, and $11.9 million in the year ended December 31, 2015. The following table summarizes the activity related to RSUs for the year ended December 31, 2017: Unvested and outstanding at January 1, 2017 Granted Vested Canceled Unvested and outstanding at December 31, 2017 80 RSUs Outstanding Weighted- Average Grant Date Fair Value Per Share 42.04 64.59 42.24 48.13 54.12 Shares (in thousands) 2,264 $ 1,189 (1,151) (217) 2,085 $ 12. Employee Stock Purchase Plan On September 25, 2014, the Company’s board of directors adopted and the Company’s stockholders approved the 2014 Employee Share Purchase Plan (the “ESPP”). The ESPP became effective upon the closing of the Company’s IPO. The ESPP authorizes the issuance of up to a total of 1,409,988 shares of common stock to participating employees, and allows eligible employees to purchase shares of common stock at a 15% discount from the fair market value of the stock as determined on specific dates at six-month intervals. The offering periods generally start on the first trading day on or after January 1st and July 1st of each year. In December 2017, the Company’s board of directors amended and restated the ESPP. In conjunction with the amendment of the ESPP, the Company amended the offering periods, which will now commence on June 1 and November 1 of each year starting with the offering period beginning with offering period in June 2018. The following table summarizes the activity related to ESPP: 2017 2016 2015 13. Income Taxes (Loss) income before provision for income taxes was as follows: United States Foreign Total The benefit (provision) for income taxes consists of the following: Current income tax provision Federal State Foreign Total current income tax provision Deferred income tax benefit Federal State Foreign Total deferred income tax benefit Total income tax benefit (provision) Shares Issued (in thousands) Weighted- Average Purchase Price 38.83 38.98 28.46 Total Cash Proceeds (in thousands) 3,635 2,721 814 94 70 29 2017 Year Ended December 31, 2016 (in thousands) 2015 $ $ (54,894) $ 4,855 (50,039) $ (47,112) $ 2,083 (45,029) $ (47,911) 2,270 (45,641) 2017 Year Ended December 31, 2016 (in thousands) 2015 $ $ — $ (144) (1,077) (1,221) 10,435 977 134 11,546 10,325 $ — $ (95) (579) (674) 61 — 80 141 (533) $ — (61) (401) (462) (10) — 60 50 (412) 81 The following reconciles the differences between income taxes computed at the federal statutory rate of 35% and the provision for income taxes: Expected income tax benefit at the federal statutory rate State taxes net of federal benefit Stock-based compensation Difference in foreign tax rates U.S. tax credits Convertible debt and acquisition Federal rate change Transition tax Change in valuation allowance Other Income tax benefit (provision) 2017 Year Ended December 31, 2016 (in thousands) 2015 $ $ 17,166 $ 5,150 10,939 988 1,717 11,573 (49,123) (1,063) 13,988 (1,010) 10,325 $ 15,761 $ 916 (2,001) 415 1,609 — — (16,413) (820) (533) $ 15,974 2,257 (1,685) 482 2,738 — — (19,421) (757) (412) On December 22, 2017, the United States of America signed tax legislation (the “2017 Act”) which enacts a wide range of changes to the U.S. corporate income tax system. The 2017 Act reduces the U.S. corporate tax rate to 21% effective in 2018, broadens the tax base and changes rules for expensing and capitalizing business expenditures, establishes a territorial tax system for foreign earnings as well as a minimum tax on certain foreign earnings, provides for a one- time transition tax on previously undistributed foreign earnings, and introduces new rules for the treatment of certain export sales. At December 31, 2017, the Company has not completed the accounting for the tax effects of enactment of the 2017 Act; however, in certain cases, as described below, the Company has made a reasonable estimate of the effects on existing deferred tax balances and the one-time transition tax. For the items for which the Company was not able to determine a reasonable estimate, no net income tax expense or benefit was recognized. The Company remeasured certain deferred tax assets and liabilities based on the rates at which they are expected to reverse in the future, which is generally 21% for U.S. federal tax purposes. However, the Company is still analyzing certain aspects of the Act and refining its calculations, which could potentially affect the measurement of these balances or potentially give rise to new deferred tax amounts. The provisional amount recorded related to the remeasurement of deferred tax balances was $49.1 million, which was offset by a corresponding reduction in the valuation allowance. The one-time transition tax is based on the Company’s total post-1986 earnings and profits (E&P) for which the Company previously deferred from U.S. income taxes. The one-time transition tax results in an estimated inclusion of $6.9 million of foreign earnings in U.S. taxable income, which reduces U.S. federal and state net operating losses generated during 2017. The Company has not yet completed the calculation of the total post-1986 foreign E&P for these foreign subsidiaries, and therefore this estimate may change as additional clarifying and interpretative technical guidance is issued related to the calculation of our one-time transition tax. The changes included in the 2017 Act are broad and complex. The final transition impacts of the 2017 Act may differ from the above estimates, possibly materially, due to, among other things, changes in interpretations of the 2017 Act, any legislative action to address questions that arise because of the 2017 Act, actions taken by U.S. state governments and taxing authorities in response to the 2017 Act, any changes in accounting standards for income taxes or related interpretations in response to the 2017 Act, or any updates or changes to estimates that have been utilized to calculate the transition impacts, including impacts from changes to current year earnings estimates and foreign exchange rates of foreign subsidiaries. The Securities Exchange Commission has issued rules that allow for a measurement period of up to one year after the enactment date of the 2017 Act to finalize the recording of the related tax impacts. The Company currently anticipate finalizing and recording any resulting adjustments during 2018. 82 Deferred Tax Assets and Liabilities —Deferred income taxes reflect the net effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purpos es. Significant components of the Company’s deferred tax assets and liabilities were as follows: Deferred tax assets: Net operating loss carryforwards Research and investment credits Accruals and reserves Depreciation Intangible assets Stock-based compensation Total deferred tax assets Deferred tax liabilities: Intangible assets Convertible debt Capitalized costs Total deferred tax liabilities Valuation allowance Net deferred tax assets Year Ended December 31, 2017 2016 (in thousands) $ $ 87,521 $ 9,402 6,627 911 — 4,146 108,607 $ (1,273) (5,664) (4,648) (11,585) (96,630) $ 392 $ 73,750 6,674 6,699 744 215 8,115 96,197 — — (4,843) (4,843) (91,132) 222 The Company reviews all available evidence to evaluate its recovery of deferred tax assets, including its recent history of accumulated losses in all tax jurisdictions over the most recent three years as well as its ability to generate income in future periods. The Company has provided a valuation allowance against its U.S. net deferred tax assets as it is more likely than not that these assets will not be realized given the nature of the assets and the likelihood of future utilization. The valuation allowance increased by $5.5 million in 2017, $16.5 million in 2016 and $19.4 million in 2015, primarily due to the increase in the U.S. net operating loss deferred tax asset. The Company does not expect any significant changes in its valuation allowance positions within the next 12 months. At December 31, 2017, undistributed foreign earnings of approximately $6.9 million have been taxed due to the one-time transition tax on previously undistributed foreign earnings required by the 2017 Act. For any future foreign earnings, the Company will generally be free of additional U.S. federal tax consequences due to a dividends received deduction implemented as part of the move to a territorial tax system for foreign subsidiary earnings. No provision has been made for additional deferred taxes related to any remaining historical outside basis differences in our non-U.S. subsidiaries, which could include U.S. state taxes and foreign withholding taxes. The Company continues to assess the impact of the 2017 Act on its indefinite reinvestment in these outside basis differences generated on or before December 31, 2017 and intends to finalize this assessment within the one-year measurement period as allowed for by the Securities and Exchange Commission. The Company had federal and state net operating loss carryforwards of $352.5 million and $224.7 million, respectively at December 31, 2017, which expire at various dates through 2037 The Company had federal research and development credit carryforwards of $5.8 million at December 31, 2017 that expire at various dates through 2037. The Company also has state research and investment credit carryforwards of $2.5 million and $756 thousand, respectively that expire at various dates through 2032. Under Section 382 of the Internal Revenue Code of 1986, as amended, substantial changes in the Company's ownership may limit the amount of net operating loss carryforwards that could be utilized annually in the future to offset taxable income. Specifically, this limitation may arise in the event of a cumulative change in ownership of the Company of more than 50% within a three-year period. Any such annual limitation may significantly reduce the utilization of net operating loss carryforwards before they expire. The Company performed an analysis through December 31, 2016, and determined any potential ownership change under Section 382 during the year would not have a material impact on the future utilization of US net operating losses and tax credits. There was no material change to this conclusion in 2017. However, future transactions in the Company's common stock could trigger an ownership change for purposes of Section 382, which could limit the amount of net operating loss carryforwards and other attributes that could be utilized annually in the future to offset taxable income, if any. Any such limitation, whether as the result of sales of common stock by our existing stockholders or sales of common stock by the Company, could have a material adverse effect on results of operations in future years. 83 Uncertain Tax Positions —The Company accounts for uncertainty in income taxes using a two-step process. The Company first determines whether it is m ore likely than not that a tax position will be sustained upon examination by the tax authority, including resolutions of any related appeals or litigation processes, based on technical merit. If a tax position meets the more-likely-than-not recognition th reshold it is then measured to determine the amount of benefit to recognize in the financial statements. The tax position is measured as the largest amount of benefit that is greater than 50% likely of being realized upon ultimate settlement. The following summarizes activity related to unrecognized tax benefits: Unrecognized benefit—beginning of the year Gross increases—current period positions Gross decrease—prior period positions Unrecognized benefit—end of period 2017 Year Ended December 31, 2016 (in thousands) 2015 $ $ 1,742 $ 983 — 2,725 $ 673 $ 1,069 — 1,742 $ 1,713 171 (1,211) 673 All of the gross unrecognized tax benefits represent a reduction to the research and development tax credit carryforward. The gross decrease to prior period positions, for the period ending December 31, 2015 is a result of the Company completing IRS documentation of all credits generated since inception. All of the unrecognized tax benefits decrease deferred tax assets with a corresponding decrease to the valuation allowance. None of the unrecognized tax benefits would affect the Company’s effective tax rate if recognized in the future. The Company has elected to recognize interest and penalties related to uncertain tax positions as a component of income tax expense. No interest or penalties have been recorded through December 31, 2017. The Company does not expect any significant change in its unrecognized tax benefits within the next 12 months. The Company files tax returns in the United States, Ireland, Australia, Singapore, Japan, Germany and various state jurisdictions. All of the Company’s tax years remain open to examination by major taxing jurisdictions to which the Company is subject, as carryforward attributes generated in past years may still be adjusted upon examination by the Internal Revenue Service or state and foreign tax authorities if they have or will be used in future periods. The Company is routinely examined by various taxing authorities. The IRS completed a federal income tax audit for the tax year 2013 during 2016 . The completed federal income tax audit did not yield a material effect on the Company’s financial condition or results of operations. 14. Employee Benefit Plan In July 2008, the Company established a defined contribution savings plan under Section 401(k) of the Internal Revenue Code. This plan covers substantially all employees who meet minimum age and service requirements and allows participants to defer a portion of their annual compensation on a pretax basis, subject to legal limitations. Total contributions were $2.9 million in 2017, $2.1 million in 2016, and $1.2 million in 2015. 84 15.

Changes in and Disagreements with Accountants on Accounting and Financial Disclosure None. ITEM 9A. Controls and Procedures (a) Evaluation of Disclosure Controls and Procedures Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the Exchange Act)), as of the end of the period covered by this Annual Report on Form 10-K. Based on such evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that as of December 31, 2017, our disclosure controls and procedures were effective at the reasonable assurance level. (b) Management’s Report on Internal Control Over Financial Reporting Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, is responsible for establishing and maintaining adequate internal control over financial reporting. Internal control over financial reporting is defined in Rules 13a-15(f) or 15d-15(f) promulgated under the Exchange Act as a process designed by, or under the supervision of, the company's principal executive and principal financial officers and effected by the company’s board of directors, management and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles and includes those policies and procedures that: • • • pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of the assets of the company; provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the company’s assets that could have a material effect on the financial statements. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. Our management assessed the effectiveness of the Company’s internal control over financial reporting as of December 31, 2017. In making this assessment, our management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control — Integrated Framework (2013). 85 Based on o ur assessment, management, with the participation of our Chief Executive Officer and Chief Financial Officer, concluded that, as of December 31, 2017, our internal control over financial reporting was effective based on those criteria. The effectiveness of the Company’s internal control over financial reporting as of December 31, 2017 has been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in its report, which is included on under Item 8 of this annual report on Form 10-K (c) Inherent Limitations of Internal Controls Our management, including our Chief Executive Officer and Chief Financial Officer, does not expect that our disclosure controls and procedures or our internal control over financial reporting will prevent all errors and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within the Company have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of a simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the control. The design of any system of controls also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Over time, controls may become inadequate because of changes in conditions, or the degree of compliance with the policies or procedures may deteriorate. Because of the inherent limitations, misstatements due to error or fraud may occur and not be detected. (d) Changes in Internal Control over Financial Reporting No change in our internal control over financial reporting occurred during the quarter ended December 31, 2017 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

(f) Foreign Award Recipients . Notwithstanding any provision of the Plan to the contrary, in order to comply with the laws in other countries in which the Company and its Subsidiaries operate or have employees or other individuals eligible for Awards, the Administrator, in its sole discretion, shall have the power and authority to: (i) determine which Subsidiaries shall be covered by the Plan; (ii) determine which individuals outside the United States are eligible to participate in the Plan; (iii) modify the terms and conditions of any Award granted to individuals outside the United States to comply with applicable foreign laws; (iv) establish subplans and modify exercise procedures and other terms and procedures, to the extent the Administrator determines such actions to be necessary or advisable (and such subplans and/or modifications shall be attached to this Plan as appendices); provided, however, that no such subplans and/or modifications shall increase the share limitations contained in Section 3(a) hereof; and (v) take any action, before or after an Award is made, that the Administrator determines to be necessary or advisable to obtain approval or comply with any local governmental regulatory exemptions or approvals. Notwithstanding the foregoing, the Administrator may not take any actions hereunder, and no Awards shall be granted, that would violate the Exchange Act or any other applicable United States securities law, the Code, or any other applicable United States governing statute or law. SECTION 3. STOCK ISSUABLE UNDER THE PLAN; MERGERS; SUBSTITUTION (a) Stock Issuable . The maximum number of shares of Stock reserved and available for issuance under the Plan shall be 1,973,551 shares (the “Initial Limit”), subject to adjustment as provided in Section 3(c), plus on January 1, 2015 and each January 1 thereafter, the number of shares of Stock reserved and available for issuance under the Plan shall be cumulatively increased by 5 percent of the number of shares of Stock issued and outstanding on the immediately preceding December 31 or such lesser number of shares of Stock as determined by the Administrator (the “Annual Increase”). Subject to such overall limitation, the maximum aggregate number of shares of Stock that may be issued in the form of Incentive Stock Options shall not exceed the Initial Limit cumulatively increased on January 1, 2015 and on each January 1 thereafter by the lesser of the Annual Increase for such year or 1,000,000 shares of Stock, subject in all cases to adjustment as provided in Section 3(c). The shares of Stock underlying any Awards under the Plan and under the Company’s 2007 Equity Incentive Plan that are forfeited, canceled, held back upon exercise of an Option or settlement of an Award to cover the exercise price or tax withholding, reacquired by the Company prior to vesting, satisfied without the issuance of Stock or otherwise terminated (other than by exercise) shall be added back to the shares of Stock available for issuance under the Plan. In the event the Company repurchases shares of Stock on the open market, such shares shall not be added to the shares of Stock ACTIVE/72134752.4 6 available for issuance under the Plan. Subject to such overall limitations, shares of Stock may be issued up to such maximum number pursuant to any type or types of Award; provided, however, that Stock Options or Stock Appreciation Rights with respect to no more than 1,000,000 shares of Stock may be granted to any one individual grantee during any one calendar year period. The shares available for issuance under the Plan may be authorized but unissued shares of Stock or shares of Stock reacquired by the Company. (b) [Reserved.] (c) Changes in Stock . Subject to Section 3(d) hereof, if, as a result of any reorganization, recapitalization, reclassification, stock dividend, stock split, reverse stock split or other similar change in the Company’s capital stock, the outstanding shares of Stock are increased or decreased or are exchanged for a different number or kind of shares or other securities of the Company, or additional shares or new or different shares or other securities of the Company or other non-cash assets are distributed with respect to such shares of Stock or other securities, or, if, as a result of any merger or consolidation, sale of all or substantially all of the assets of the Company, the outstanding shares of Stock are converted into or exchanged for securities of the Company or any successor entity (or a parent or subsidiary thereof), the Administrator shall make an appropriate or proportionate adjustment in (i) the maximum number of shares reserved for issuance under the Plan, including the maximum number of shares that may be issued in the form of Incentive Stock Options, (ii) the number of Stock Options or Stock Appreciation Rights that can be granted to any one individual grantee and the maximum number of shares that may be granted under a Performance-Based Award, (iii) the number and kind of shares or other securities subject to any then outstanding Awards under the Plan, (iv) the repurchase price, if any, per share subject to each outstanding Restricted Stock Award, and (v) the exercise price for each share subject to any then outstanding Stock Options and Stock Appreciation Rights under the Plan, without changing the aggregate exercise price (i.e., the exercise price multiplied by the number of Stock Options and Stock Appreciation Rights) as to which such Stock Options and Stock Appreciation Rights remain exercisable. The Administrator shall also make equitable or proportionate adjustments in the number of shares subject to outstanding Awards and the exercise price and the terms of outstanding Awards to take into consideration cash dividends paid other than in the ordinary course or any other extraordinary corporate event. The adjustment by the Administrator shall be final, binding and conclusive. No fractional shares of Stock shall be issued under the Plan resulting from any such adjustment, but the Administrator in its discretion may make a cash payment in lieu of fractional shares. (d) Mergers and Other Transactions . In the case of and subject to the consummation of a Sale Event, the parties thereto may cause the assumption or continuation of Awards theretofore granted by the successor entity, or the substitution of such Awards with new Awards of the successor entity or parent thereof, with appropriate adjustment as to the number and kind of shares and, if appropriate, the per share exercise prices, as such parties shall agree. To the extent the parties to such Sale Event do not provide for the assumption, continuation or substitution of Awards, upon the effective time of the Sale Event, the Plan and all outstanding Awards granted hereunder shall terminate. In such case except as may be otherwise provided in the relevant Award Certificate, all Options and Stock Appreciation Rights that are not exercisable immediately prior to the effective time of the Sale Event shall become fully exercisable as of the effective time of the Sale Event, all other Awards with time-based vesting, ACTIVE/72134752.4 7 conditions or restrictions shall become fully vested and nonforfeitable as of the effective time of the Sale Event and all Awards with conditions and restrictions relating to the attainment of performance goals may become vested and nonforfeitable in connection with a Sale Event in the Administrator’s discretion or to the extent specified in the relevant Award Certificate . In the event of such termination, (i) the Company shall have the option (in its sole discretion) to make or provide for a cash payment to the grantees holding Options and Stock Appreciation Rights, in exchange for the cancellation thereof, in an amount equal to the difference between (A) the Sale Price multiplied by the number of shares of Stock subject to outstanding Options and Stock Appreciation Rights (to the extent then exercisable at prices not in excess of the Sale Price) and (B) the aggregate exercise price of all such outstanding Options and Stock Appreciation Rights; or (ii) each grantee shall be permitted, within a specified period of time prior to the consummation of the Sale Event as determined by the Administrator, to exercise all outstanding Options and Stock Appreciation Rights (to the extent then exercisable) held by such grantee. (e) Substitute Awards . The Administrator may grant Awards under the Plan in substitution for stock and stock based awards held by employees, directors or other key persons of another corporation in connection with the merger or consolidation of the employing corporation with the Company or a Subsidiary or the acquisition by the Company or a Subsidiary of property or stock of the employing corporation. The Administrator may direct that the substitute awards be granted on such terms and conditions as the Administrator considers appropriate in the circumstances. Any substitute Awards granted under the Plan shall not count against the share limitation set forth in Section 3(a). SECTION 4. ELIGIBILITY Grantees under the Plan will be such full or part-time officers and other employees, Non-Employee Directors and Consultants of the Company and its Subsidiaries as are selected from time to time by the Administrator in its sole discretion. SECTION 5. STOCK OPTIONS (a) Award of Stock Options . The Administrator may grant Stock Options under the Plan. Any Stock Option granted under the Plan shall be in such form as the Administrator may from time to time approve. Stock Options granted under the Plan may be either Incentive Stock Options or Non-Qualified Stock Options. Incentive Stock Options may be granted only to employees of the Company or any Subsidiary that is a “subsidiary corporation” within the meaning of Section 424(f) of the Code. To the extent that any Option does not qualify as an Incentive Stock Option, it shall be deemed a Non-Qualified Stock Option. Stock Options granted pursuant to this Section 5 shall be subject to the following terms and conditions and shall contain such additional terms and conditions, not inconsistent with the terms of the Plan, as the Administrator shall deem desirable. If the Administrator so determines, Stock Options may be granted in lieu of cash compensation at the optionee’s election, subject to such terms and conditions as the Administrator may establish. ACTIVE/72134752.4 8 (b) Exercise Price . The exercise price per share for the Stock covered by a Stock Option granted pursuant to this Section 5 shall be determined by the Administrator at the time of grant but shall not be less than 100 percent of the Fair Market Value on the date of grant. In the case of an Incentive Stock Option that is granted to a Ten Percent Owner, the option price of such Incentive Stock Option shall be not less than 110 percent of the Fair Market Value on the grant date. (c) Option Term . The term of each Stock Option shall be fixed by the Administrator, but no Stock Option shall be exercisable more than ten years after the date the Stock Option is granted. In the case of an Incentive Stock Option that is granted to a Ten Percent Owner, the term of such Stock Option shall be no more than five years from the date of grant. (d) Exercisability; Rights of a Stockholder . Stock Options shall become exercisable at such time or times, whether or not in installments, as shall be determined by the Administrator at or after the grant date. The Administrator may at any time accelerate the exercisability of all or any portion of any Stock Option. An optionee shall have the rights of a stockholder only as to shares acquired upon the exercise of a Stock Option and not as to unexercised Stock Options. (e) Method of Exercise . Stock Options may be exercised in whole or in part, by giving written or electronic notice of exercise to the Company, specifying the number of shares to be purchased. Payment of the purchase price may be made by one or more of the following methods except to the extent otherwise provided in the Option Award Certificate: (i) In cash, by certified or bank check or other instrument acceptable to the Administrator; (ii) Through the delivery (or attestation to the ownership following such procedures as the Company may prescribe) of shares of Stock that are not then subject to restrictions under any Company plan. Such surrendered shares shall be valued at Fair Market Value on the exercise date; (iii) By the optionee delivering to the Company a properly executed exercise notice together with irrevocable instructions to a broker to promptly deliver to the Company cash or a check payable and acceptable to the Company for the purchase price; provided that in the event the optionee chooses to pay the purchase price as so provided, the optionee and the broker shall comply with such procedures and enter into such agreements of indemnity and other agreements as the Company shall prescribe as a condition of such payment procedure; or (iv) With respect to Stock Options that are not Incentive Stock Options, by a “net exercise” arrangement pursuant to which the Company will reduce the number of shares of Stock issuable upon exercise by the largest whole number of shares with a Fair Market Value that does not exceed the aggregate exercise price. Payment instruments will be received subject to collection. The transfer to the optionee on the records of the Company or of the transfer agent of the shares of Stock to be purchased pursuant to the exercise of a Stock Option will be contingent upon receipt from the optionee (or a purchaser acting in his stead in accordance with the provisions of the Stock Option) by the Company of the full purchase price for such shares and the fulfillment of any other requirements ACTIVE/72134752.4 9 contained in the Option Award Certificate or applicable provisions of laws (including the satisfaction of any withholding taxes that the Company is obligated to withhold with respect to the optionee). In the event an optionee chooses to pay the purchase price by previously-owned shares of Stock through the attestation method, the number of shares of Stock transferred to the optionee upon the exercise of the Stock Option shall be net of the number of attested shares. In the event that the Company establishes, for itself or using the services of a third party, an automated system for the exercise of Stock Options, such as a system using an internet website or interactive voice response, then the paperless exercise of Stock Options may be permitted through the use of such an automated system. (f) Annual Limit on Incentive Stock Options . To the extent required for “incentive stock option” treatment under Section 422 of the Code, the aggregate Fair Market Value (determined as of the time of grant) of the shares of Stock with respect to which Incentive Stock Options granted under this Plan and any other plan of the Company or its parent and subsidiary corporations become exercisable for the first time by an optionee during any calendar year shall not exceed $100,000. To the extent that any Stock Option exceeds this limit, it shall constitute a Non-Qualified Stock Option. SECTION 6. STOCK APPRECIATION RIGHTS (a) Award of Stock Appreciation Rights . The Administrator may grant Stock Appreciation Rights under the Plan. A Stock Appreciation right is an award entitling the recipient to receive shares of Stock having a value equal to the excess of the Fair Market Value of a share of Stock on the date of exercise over the exercise price of the Stock Appreciation Right multiplied by the number of shares of Stock with respect to which the Stock Appreciation Right shall have been exercised. (b) Exercise Price of Stock Appreciation Rights . The exercise price of a Stock Appreciation Right shall not be less than 100 percent of the Fair Market Value of the Stock on the date of grant. (c) Grant and Exercise of Stock Appreciation Rights . Stock Appreciation Rights may be granted by the Administrator independently of any Stock Option granted pursuant to Section 5 of the Plan. (d) Terms and Conditions of Stock Appreciation Rights . Stock Appreciation Rights shall be subject to such terms and conditions as shall be determined from time to time by the Administrator. The term of a Stock Appreciation Right may not exceed ten years. SECTION 7. RESTRICTED STOCK AWARDS (a) Nature of Restricted Stock Awards . The Administrator may grant Restricted Stock awards under the Plan. A Restricted Stock Award is any Award of Restricted Shares subject to such restrictions and conditions as the Administrator may determine at the time of grant. Conditions may be based on continuing employment (or other service relationship) and/or achievement of pre-established performance goals and objectives. The terms and conditions of each such Award Certificate shall be determined by the Administrator, and such terms and conditions may differ among individual Awards and grantees. ACTIVE/72134752.4 10 (b) Rights as a Stockholder . Upon the grant of the Restricted Stock Award and payment of any applicable purchase price, a grantee shall have the rights of a stockholder with respect to the voting of the Restricted Shares and receipt of dividends; provided that if the lapse of restrictions with respect to the Restricted Stock Award is tied to the attainment of performance goals, any dividends paid by the Company during the performance period shall accrue and shall not be paid to the grantee until and to the extent the performance goals are met with respect to the Restricted Stock Award. Unless the Administrator shall otherwise determine, (i) uncertificated Restricted Shares shall be accompanied by a notation on the records of the Company or the transfer agent to the effect that they are subject to forfeiture until such Restricted Shares are vested as provided in Section 7(d) below, and (ii) certificated Restricted Shares shall remain in the possession of the Company until such Restricted Shares are vested as provided in Section 7(d) below, and the grantee shall be required, as a condition of the grant, to deliver to the Company such instruments of transfer as the Administrator may prescribe. (c) Restrictions . Restricted Shares may not be sold, assigned, transferred, pledged or otherwise encumbered or disposed of except as specifically provided herein or in the Restricted Stock Award Certificate. Except as may otherwise be provided by the Administrator either in the Award Certificate or, subject to Section 18 below, in writing after the Award is issued, if a grantee’s employment (or other service relationship) with the Company and its Subsidiaries terminates for any reason, any Restricted Shares that have not vested at the time of termination shall automatically and without any requirement of notice to such grantee from or other action by or on behalf of, the Company be deemed to have been reacquired by the Company at its original purchase price (if any) from such grantee or such grantee’s legal representative simultaneously with such termination of employment (or other service relationship), and thereafter shall cease to represent any ownership of the Company by the grantee or rights of the grantee as a stockholder. Following such deemed reacquisition of Restricted Shares that are represented by physical certificates, a grantee shall surrender such certificates to the Company upon request without consideration. (d) Vesting of Restricted Shares . The Administrator at the time of grant shall specify the date or dates and/or the attainment of pre-established performance goals, objectives and other conditions on which the non-transferability of the Restricted Shares and the Company’s right of repurchase or forfeiture shall lapse. Subsequent to such date or dates and/or the attainment of such pre-established performance goals, objectives and other conditions, the shares on which all restrictions have lapsed shall no longer be Restricted Stock and shall be deemed “vested.” Except as may otherwise be provided by the Administrator either in the Award Certificate or, subject to Section 18 below, in writing after the Award is issued, a grantee’s rights in any Restricted Shares that have not vested shall automatically terminate upon the grantee’s termination of employment (or other service relationship) with the Company and its Subsidiaries and such shares shall be subject to the provisions of Section 7(c) above. SECTION 8. RESTRICTED STOCK UNITS (a) Nature of Restricted Stock Units . The Administrator may grant Restricted Stock Units under the Plan. A Restricted Stock Unit is an Award of stock units that may be settled in shares of Stock upon the satisfaction of such restrictions and conditions at the time of grant. Conditions may be based on continuing employment (or other service relationship) and/or ACTIVE/72134752.4 11 achievement of pre-established performance goals and objectives. The terms and conditions of each such Award Certificate shall be determined by the Administrator, and such terms and conditions may differ among individual Awards and grantees. Except in the case of Restricted Stock Units with a deferred settlement date that complies with Section 409A, at the end of the vesting period, vested Restricted Stock Units shall be settled in the form of shares of Stock. Restricted Stock Units with deferred settlement dates are subject to Section 409A, and shall contain such additional terms and conditions as the Administrator shall determine in its sole discretion in order to comply with the requirements of Section 409A. (b) Election to Receive Restricted Stock Units in Lieu of Compensation . The Administrator may, in its sole discretion, permit a grantee to elect to receive a portion of future cash compensation otherwise due to such grantee in the form of an award of Restricted Stock Units. Any such election shall be made in writing and shall be delivered to the Company no later than the date specified by the Administrator and in accordance with Section 409A and such other rules and procedures established by the Administrator. Any such future cash compensation that the grantee elects to defer shall be converted to a fixed number of Restricted Stock Units based on the Fair Market Value of Stock on the date the compensation would otherwise have been paid to the grantee if such payment had not been deferred as provided herein. The Administrator shall have the sole right to determine whether and under what circumstances to permit such elections and to impose such limitations and other terms and conditions thereon as the Administrator deems appropriate. Any Restricted Stock Units that are elected to be received in lieu of cash compensation shall be fully vested, unless otherwise provided in the Award Certificate. (c) Rights as a Stockholder . A grantee shall have the rights as a stockholder only as to shares of Stock acquired by the grantee upon settlement of Restricted Stock Units; provided, however, that the grantee may be credited with Dividend Equivalent Rights with respect to the stock units underlying his Restricted Stock Units, subject to the provisions of Section 11 and such terms and conditions as the Administrator may determine. (d) Termination . Except as may otherwise be provided by the Administrator either in the Award Certificate or, subject to Section 18 below, in writing after the Award is issued, a grantee’s right in all Restricted Stock Units that have not vested shall automatically terminate upon the grantee’s termination of employment (or cessation of service relationship) with the Company and its Subsidiaries for any reason. SECTION 9. UNRESTRICTED STOCK AWARDS Grant or Sale of Unrestricted Stock . The Administrator may grant (or sell at par value or such higher purchase price determined by the Administrator) an Unrestricted Stock Award under the Plan. An Unrestricted Stock Award is an Award pursuant to which the grantee may receive shares of Stock free of any restrictions under the Plan. Unrestricted Stock Awards may be granted in respect of past services or other valid consideration, or in lieu of cash compensation due to such grantee. ACTIVE/72134752.4 12 SECTION 10. CASH-BASED AWARDS Grant of Cash-Based Awards . The Administrator may grant Cash-Based Awards under the Plan. A Cash-Based Award is an award that entitles the grantee to a payment in cash upon the attainment of specified Performance Goals. The Administrator shall determine the maximum duration of the Cash-Based Award, the amount of cash to which the Cash-Based Award pertains, the conditions upon which the Cash-Based Award shall become vested or payable, and such other provisions as the Administrator shall determine. Each Cash-Based Award shall specify a cash-denominated payment amount, formula or payment ranges as determined by the Administrator. Payment, if any, with respect to a Cash-Based Award shall be made in accordance with the terms of the Award and may be made in cash. SECTION 11. PERFORMANCE SHARE AWARDS (a) Nature of Performance Share Awards . The Administrator may grant Performance Share Awards under the Plan. A Performance Share Award is an Award entitling the grantee to receive shares of stock upon the attainment of performance goals. The Administrator shall determine whether and to whom Performance Share Awards shall be granted, the Performance Goals, the periods during which performance is to be measured, which may not be less than one year except in the case of a Sale Event, and such other limitations and conditions as the Administrator shall determine. (b) Rights as a Stockholder . A grantee receiving a Performance Share Award shall have the rights of a stockholder only as to shares of Stock actually received by the grantee under the Plan and not with respect to shares subject to the Award but not actually received by the grantee. A grantee shall be entitled to receive shares of Stock under a Performance Share Award only upon satisfaction of all conditions specified in the Performance Share Award Certificate (or in a performance plan adopted by the Administrator). (c) Termination . Except as may otherwise be provided by the Administrator either in the Award agreement or, subject to Section 18 below, in writing after the Award is issued, a grantee’s rights in all Performance Share Awards shall automatically terminate upon the grantee’s termination of employment (or cessation of service relationship) with the Company and its Subsidiaries for any reason. SECTION 12. PERFORMANCE-BASED AWARDS TO COVERED EMPLOYEES (a) Performance-Based Awards . The Administrator may grant one or more Performance-Based Awards in the form of a Restricted Stock Award, Restricted Stock Units, Performance Share Awards or Cash-Based Award payable upon the attainment of Performance Goals that are established by the Administrator and relate to one or more of the Performance Criteria, in each case on a specified date or dates or over any period or periods determined by the Administrator. The Administrator shall define in an objective fashion the manner of calculating the Performance Criteria it selects to use for any Performance Cycle. Depending on the Performance Criteria used to establish such Performance Goals, the Performance Goals may be expressed in terms of overall Company performance or the performance of a division, business unit, or an individual. Each Performance-Based Award shall comply with the provisions set forth below. ACTIVE/72134752.4 13 (b) Grant of Performance-Based Awards . With respect to each Performance-Based Award granted to a Covered Employee (or any other eligible individual that the Administrator determines is reasonably likely to become a Covered Employee) , the Administrator shall select, within the first 90 days of a Performance Cycle (or, if shorter, within the maximum period allowed under Section 162(m) of the Code) the Performance Criteria for such grant, and the Performance Goals with respect to each Performance Criterion (including a threshold level of performance below which no amount will become payable with respect to such Award). Each Performance-Based Award will specify the amount payable, or the formula for determining the amount payable, upon achievement of the various applicable performance targets. The Performance Criteria established by the Administrator may be (but need not be) different for each Performance Cycle and different Performance Goals may be applicable to Performance-Based Awards to different Covered Employees. (c) Payment of Performance-Based Awards . Following the completion of a Performance Cycle, the Administrator shall meet to review and certify in writing whether, and to what extent, the Performance Goals for the Performance Cycle have been achieved and, if so, to also calculate and certify in writing the amount of the Performance-Based Awards earned for the Performance Cycle. The Administrator shall then determine the actual size of each Covered Employee’s Performance-Based Award, and, in doing so, may reduce or eliminate the amount of the Performance-Based Award for a Covered Employee if, in its sole judgment, such reduction or elimination is appropriate. (d) Maximum Award Payable . The maximum Performance-Based Award payable to any one Covered Employee under the Plan for a Performance Cycle is 1,000,000 shares of Stock (subject to adjustment as provided in Section 3(c) hereof) or $2,000,000 in the case of a Performance-Based Award that is a Cash-Based Award. SECTION 13. DIVIDEND EQUIVALENT RIGHTS (a) Dividend Equivalent Rights . The Administrator may grant Dividend Equivalent Rights under the Plan. A Dividend Equivalent Right is an Award entitling the grantee to receive credits based on cash dividends that would have been paid on the shares of Stock specified in the Dividend Equivalent Right (or other Award to which it relates) if such shares had been issued to the grantee. A Dividend Equivalent Right may be granted hereunder to any grantee as a component of an award of Restricted Stock Units, Restricted Stock Award or Performance Share Award or as a freestanding award. The terms and conditions of Dividend Equivalent Rights shall be specified in the Award Certificate. Dividend equivalents credited to the holder of a Dividend Equivalent Right may be paid currently or may be deemed to be reinvested in additional shares of Stock, which may thereafter accrue additional equivalents. Any such reinvestment shall be at Fair Market Value on the date of reinvestment or such other price as may then apply under a dividend reinvestment plan sponsored by the Company, if any. Dividend Equivalent Rights may be settled in cash or shares of Stock or a combination thereof, in a single installment or installments. A Dividend Equivalent Right granted as a component of an award of Restricted Stock Units or Restricted Stock Award with performance vesting or Performance Share Award shall provide that such Dividend Equivalent Right shall be settled only upon settlement or payment of, or lapse of restrictions on, such other Award, and that such Dividend Equivalent Right shall expire or be forfeited or annulled under the same conditions as such other Award. ACTIVE/72134752.4 14 (b) Termination . Except as may otherwise be provided by the Administrator either in the Award Certificate or, subject to Section 18 below, in writing after the Award is issued, a grantee’s rights in all Dividend Equivalent Rights shall automatically terminate upon the grantee’s termination of employment (or cessation of service relationship) with the Company and its Subsidiaries for any reason. SECTION 14. TRANSFERABILITY OF AWARDS (a) Transferability . Except as provided in Section 14(b) below, during a grantee’s lifetime, his or her Awards shall be exercisable only by the grantee, or by the grantee’s legal representative or guardian in the event of the grantee’s incapacity. No Awards shall be sold, assigned, transferred or otherwise encumbered or disposed of by a grantee other than by will or by the laws of descent and distribution or pursuant to a domestic relations order. No Awards shall be subject, in whole or in part, to attachment, execution, or levy of any kind, and any purported transfer in violation hereof shall be null and void. (b) Administrator Action . Notwithstanding Section 14(a), the Administrator, in its discretion, may provide either in the Award Certificate regarding a given Award or by subsequent written approval that the grantee (who is an employee or director) may transfer his or her Non-Qualified Options to his or her immediate family members, to trusts for the benefit of such family members, or to partnerships in which such family members are the only partners, provided that the transferee agrees in writing with the Company to be bound by all of the terms and conditions of this Plan and the applicable Award. In no event may an Award be transferred by a grantee for value. (c) Family Member . For purposes of Section 14(b), “family member” shall mean a grantee’s child, stepchild, grandchild, parent, stepparent, grandparent, spouse, former spouse, sibling, niece, nephew, mother-in-law, father-in-law, son-in-law, daughter-in-law, brother-in-law, or sister-in-law, including adoptive relationships, any person sharing the grantee’s household (other than a tenant of the grantee), a trust in which these persons (or the grantee) have more than 50 percent of the beneficial interest, a foundation in which these persons (or the grantee) control the management of assets, and any other entity in which these persons (or the grantee) own more than 50 percent of the voting interests. (d) Designation of Beneficiary . To the extent permitted by the Company, each grantee to whom an Award has been made under the Plan may designate a beneficiary or beneficiaries to exercise any Award or receive any payment under any Award payable on or after the grantee’s death. Any such designation shall be on a form provided for that purpose by the Administrator and shall not be effective until received by the Administrator. If no beneficiary has been designated by a deceased grantee, or if the designated beneficiaries have predeceased the grantee, the beneficiary shall be the grantee’s estate. SECTION 15. TAX WITHHOLDING (a) Payment by Grantee . Each grantee shall, no later than the date as of which the value of an Award or of any Stock or other amounts received thereunder first becomes includable in the gross income of the grantee for Federal income tax purposes, pay to the ACTIVE/72134752.4 15 Company, or make arrangements satisfactory to the Administrator regarding payment of, any Federal, state, or local taxes of any kind required by law to be withheld by the Company with respect to such income. The Company and its Subsidiaries shall, to the extent permitted by law, have the right to deduct any such taxes from any payment of any kind otherwise due to the grantee. The Company’s obligation to deliver evidence of book entry (or stock certificates) to any grantee is subject to and conditioned on tax withholding obligations being satisfied by the grantee. (b) Payment in Stock . Subject to approval by the Administrator, the Company’s minimum required tax withholding obligation may be satisfied, in whole or in part, by the Company withholding from shares of Stock to be issued pursuant to any Award a number of shares with an aggregate Fair Market Value (as of the date the withholding is effected) that would satisfy the withholding amount due. The Administrator may also require Awards to be subject to mandatory share withholding up to the required withholding amount. For purposes of share withholding, the Fair Market Value of withheld shares shall be determined in the same manner as the value of Stock includible in income of the grantee. SECTION 16. SECTION 409A AWARDS To the extent that any Award is determined to constitute “nonqualified deferred compensation” within the meaning of Section 409A (a “409A Award”), the Award shall be subject to such additional rules and requirements as specified by the Administrator from time to time in order to comply with Section 409A. In this regard, if any amount under a 409A Award is payable upon a “separation from service” (within the meaning of Section 409A) to a grantee who is then considered a “specified employee” (within the meaning of Section 409A), then no such payment shall be made prior to the date that is the earlier of (i) six months and one day after the grantee’s separation from service, or (ii) the grantee’s death, but only to the extent such delay is necessary to prevent such payment from being subject to interest, penalties and/or additional tax imposed pursuant to Section 409A. Further, the settlement of any such Award may not be accelerated except to the extent permitted by Section 409A. SECTION 17. TERMINATION OF EMPLOYMENT. TRANSFER, LEAVE OF ABSENCE, ETC. (a) Termination of Employment . If the grantee’s employer ceases to be a Subsidiary, the grantee shall be deemed to have terminated employment for the purposes of the Plan. For purposes of the Plan, the following events shall not be deemed a termination of employment: (b) a transfer to the employment of the Company from a Subsidiary or from the Company to a Subsidiary, or from one Subsidiary to another; or (c) an approved leave of absence for military service or sickness, or for any other purpose approved by the Company, if the employee’s right to re-employment is guaranteed either by a statute or by contract or under the policy pursuant to which the leave of absence was granted or if the Administrator otherwise so provides in writing. ACTIVE/72134752.4 16 Unless the Administrator provides otherwise or as required by law, vesting of Awards granted hereunder shall be suspended during any unpaid leave of absence of such grantee that exceeds a period of seven (7) days . SECTION 18. AMENDMENTS AND TERMINATION The Board may, at any time, amend or discontinue the Plan and the Administrator may, at any time, amend or cancel any outstanding Award for the purpose of satisfying changes in law or for any other lawful purpose, but no such action shall adversely affect rights under any outstanding Award without the holder’s consent. Except as provided in Section 3(c) or 3(d), without prior stockholder approval, in no event may the Administrator exercise its discretion to reduce the exercise price of outstanding Stock Options or Stock Appreciation Rights or effect repricing through cancellation and re-grants or cancellation of Stock Options or Stock Appreciation Rights in exchange for cash. To the extent required under the rules of any securities exchange or market system on which the Stock is listed, to the extent determined by the Administrator to be required by the Code to ensure that Incentive Stock Options granted under the Plan are qualified under Section 422 of the Code, or to ensure that compensation earned under Awards qualifies as performance-based compensation under Section 162(m) of the Code, Plan amendments shall be subject to approval by the Company stockholders entitled to vote at a meeting of stockholders. Nothing in this Section 18 shall limit the Administrator’s authority to take any action permitted pursuant to Section 3(c) or 3(d). SECTION 19. STATUS OF PLAN With respect to the portion of any Award that has not been exercised and any payments in cash, Stock or other consideration not received by a grantee, a grantee shall have no rights greater than those of a general creditor of the Company unless the Administrator shall otherwise expressly determine in connection with any Award or Awards. In its sole discretion, the Administrator may authorize the creation of trusts or other arrangements to meet the Company’s obligations to deliver Stock or make payments with respect to Awards hereunder, provided that the existence of such trusts or other arrangements is consistent with the foregoing sentence. SECTION 20. GENERAL PROVISIONS (a) No Distribution . The Administrator may require each person acquiring Stock pursuant to an Award to represent to and agree with the Company in writing that such person is acquiring the shares without a view to distribution thereof. (b) Delivery of Stock Certificates . Stock certificates to grantees under this Plan shall be deemed delivered for all purposes when the Company or a stock transfer agent of the Company shall have mailed such certificates in the United States mail, addressed to the grantee, at the grantee’s last known address on file with the Company. Uncertificated Stock shall be deemed delivered for all purposes when the Company or a Stock transfer agent of the Company shall have given to the grantee by electronic mail (with proof of receipt) or by United States mail, addressed to the grantee, at the grantee’s last known address on file with the Company, notice of issuance and recorded the issuance in its records (which may include electronic “book entry” records). Notwithstanding anything herein to the contrary, the Company shall not be ACTIVE/72134752.4 17 required to issue or deliver any certificates evidencing shares of Stock pursuant to the exercise of any Award, unless and until the Administrator has determined, with advice of counsel (to the extent the Administrator deems such advice necessary or advisable), that the issuance and delivery of such certificates is in compliance with all applicable laws, regulations of governmental authorities and, if applicable, the requirements of any exchange on which the shares of Stock are listed, quoted or traded. All Stock certificates delivered pursuant to the Plan shall be subject to any stop-transfer orders and other restrictions as the Administrator deems necessary or advisable to comply with federal, state or foreign jurisdiction, securities or other laws, rules and quotation system on which the Stock is listed, quoted or traded. The Administrator may place legends on any Stock certificate to reference restrictions applicable to the Stock. In addition to the terms and conditions provided herein, the Administrator may require that an individual make such reasonable covenants, agreements, and representations as the Administrator, in its discretion, deems necessary or advisable in order to comply with any such laws, regulations, or requirements. The Administrator shall have the right to require any individual to comply with any timing or other restrictions with respect to the settlement or exercise of any Award, including a window-period limitation, as may be imposed in the discretion of the Administrator. (c) Stockholder Rights . Until Stock is deemed delivered in accordance with Section 20(b), no right to vote or receive dividends or any other rights of a stockholder will exist with respect to shares of Stock to be issued in connection with an Award, notwithstanding the exercise of a Stock Option or any other action by the grantee with respect to an Award. (d) Other Compensation Arrangements; No Employment Rights . Nothing contained in this Plan shall prevent the Board from adopting other or additional compensation arrangements, including trusts, and such arrangements may be either generally applicable or applicable only in specific cases. The adoption of this Plan and the grant of Awards do not confer upon any employee any right to continued employment with the Company or any Subsidiary. (e) Trading Policy Restrictions . Option exercises and other Awards under the Plan shall be subject to the Company’s insider trading policies and procedures, as in effect from time to time. (f) Clawback Policy . Awards under the Plan shall be subject to the Company’s clawback policy, as may be adopted and as in effect from time to time. SECTION 21. EFFECTIVE DATE OF PLAN This Plan shall become effective immediately prior to the Company’s Initial Public Offering, following stockholder approval of the Plan in accordance with applicable state law, the Company’s bylaws and articles of incorporation, and applicable stock exchange rules or pursuant to written consent. No grants of Stock Options and other Awards may be made hereunder after the tenth anniversary of the Effective Date and no grants of Incentive Stock Options may be made hereunder after the tenth anniversary of the date the Plan is approved by the Board. ACTIVE/72134752.4 18 SECTION 22. GOVERNING LAW This Plan and all Awards and actions taken thereunder shall be governed by, and construed in accordance with, the laws of the State of Delaware, applied without regard to conflict of law principles.

Vesting Schedule . No portion of this Stock Option may be exercised until such portion shall have become vested and exercisable. Except as set forth below, and subject to the discretion of the Administrator (as defined in Section 2 of the Plan) to accelerate the vesting schedule hereunder, the Option Shares shall vest and become exercisable [in [ ] installments] following the Vesting Commencement Date, provided the Optionee remains an employee of the Company or a Subsidiary on each such date. Once vested and exercisable, this Stock Option shall continue to be exercisable at any time or times prior to the close of business on the Expiration Date, subject to the provisions hereof and of the Plan. Notwithstanding the foregoing, in the event of a Sale Event (as defined in the Plan) in which this Stock Option is continued or assumed by a successor to the Company, this Stock Option shall be deemed vested and exercisable upon the date on which the Optionee’s employment or service relationship with the Company and any subsidiary or successor entity, as the case may be, terminates if such termination occurs (i) within 12 months after such Sale Event or 90 days prior to such Sale Event, and (ii) such termination is by the Company or any subsidiary or successor entity without Cause or by the Optionee for Good Reason. ACTIVE/72153934.3 The following definitions shall apply: “ Cause ” shall mean (i) the Optionee’s dishonest statements or acts with respect to the Company or any affiliate of the Company, or any current or prospective customers, suppliers vendors or other third parties with which such entity does business; (ii) the Optionee’s commission of (A) a felony or (B) any misdemeanor involving moral turpitude, deceit, dishonesty or fraud; (iii) the Optionee’s failure to perform his assigned duties and responsibilities to the reasonable satisfaction of the Company which failure continues, in the reasonable judgment of the Company, after written notice given to the Optionee by the Company; (iv) the Optionee’s gross negligence, willful misconduct or insubordination with respect to the Company or any Affiliate of the Company (including, but not limited to, any violation of the Company’s code of conduct, insider trading, willful accounting improprieties or failure to cooperate with investigations); or (v) the Optionee’s material violation of any provision of any agreement(s) between the Optionee and the Company relating to noncompetition, nonsolicitation, nondisclosure and/or assignment of inventions. “Good Reason” shall mean (i) a material diminution in the Optionee’s base salary except for across-the-board salary reductions similarly affecting all or substantially all similarly situated employees of the Company or (ii) a change of more than 50 miles in the geographic location at which the Optionee provides services to the Company, so long as the Optionee provides notice to the Company within at least 90 days following the initial occurrence of any such event and the Company fails to cure such event within 30 days of such notice. 2. Manner of Exercise . (a) The Optionee may exercise this Stock Option only in the following manner: from time to time on or prior to the Expiration Date of this Stock Option, the Optionee may give written notice to the Administrator of his or her election to purchase some or all of the Option Shares purchasable at the time of such notice. This notice shall specify the number of Option Shares to be purchased. Payment of the purchase price for the Option Shares may be made by one or more of the following methods: (i) in cash, by certified or bank check or other instrument acceptable to the Administrator; (ii) through the delivery (or attestation to the ownership) of shares of Stock that have been purchased by the Optionee on the open market or that are beneficially owned by the Optionee and are not then subject to any restrictions under any Company plan and that otherwise satisfy any holding periods as may be required by the Administrator; or (iii) by the Optionee delivering to the Company a properly executed exercise notice together with irrevocable instructions to a broker to promptly deliver to the Company cash or a check payable and acceptable to the Company to pay the option purchase price, provided that in the event the Optionee chooses to pay the option purchase price as so provided, the Optionee and the broker shall comply with such procedures and enter into such agreements of indemnity and other agreements as the Administrator shall prescribe as a condition of such payment procedure; or (iv) a combination of (i), (ii) and (iii) above. Payment instruments will be received subject to collection.
