ITEM 1.    BUSINESS

Overview

We are a leading provider of global enterprise cloud communications, video meetings, collaboration, and contact center software-as-a-service (“SaaS”)
solutions.  We  believe  that  our  innovative,  cloud-based  communication  and  contact  center  solutions  disrupt  the  large  market  for  business  communications  and
collaboration  by  providing  flexible  and  cost-effective  solutions  that  support  mobile  and  distributed  workforces.  We  enable  convenient  and  effective
communications for organizations across all their locations and employees, enabling them to be more productive and more responsive to their customers.

Our cloud-based solutions are designed to be easy to use, providing a single user identity across multiple locations and devices, including smartphones,
tablets,  PCs  and  desk  phones.  Our  solutions  can  be  deployed  rapidly  and  configured  and  managed  easily.  Our  cloud-based  solutions  are  location  and  device
independent and better suited to address the needs of modern mobile and global enterprise workforces than are legacy on-premise systems. Through our platform,
we enable third-party developers and customers to integrate our solution with leading business applications to customize their own business workflows.

The rapid growth of mobile communications has changed the way businesses interact. Employees connect from anywhere with any device, using multiple
modes of communications including voice, video, text, messaging, and social media. These forms of flexible communications enable employees to be productive in
ways that traditional on-premise systems do not support.

We believe RingCentral benefits from both the shift to mobile and distributed workforces and the migration of hardware on-premise based communication
systems  to  cloud-based  software  solutions.  Our  cloud  communications  and  contact  center  solutions  are  based  on  our  Message  Video  Phone  ("MVP")  platform,
which has been designed from the ground up, specifically for today’s mobile and distributed workforce. In addition, our differentiated open platform Application
Programming Interfaces (“APIs”) enable seamless integration with third-party and custom software applications. These integrations improve business workflows
resulting in higher employee productivity and better customer service. Our global delivery capabilities support the needs of multi-national enterprises in multiple
countries.

Table of Contents

We offer three key products in our portfolio, including:

•

•

•

RingCentral Office, a Unified Communications as a Service ("UCaaS") platform, including team messaging, video meetings, and a cloud phone
system;

RingCentral cloud Contact Center as a Service ("CCaaS"); and

RingCentral Glip ("Glip"), our new branded video meeting solution with team messaging that enables smart video meetings that was launched in
2020.

We generate revenues primarily from the sale of subscriptions for our cloud-based services. We focus on acquiring and retaining our customers, adding
value  to  their  experience,  and  increasing  their  use  of  our  solutions.  As  their  needs  change,  customers  add  users  to  services,  upgrade  to  premium  subscription
editions which provide additional features and functionality and expand their use of other solutions.

We use our direct and indirect sales channels to market our brand and sell our solutions. Key developments in our go-to-market expansion:

•

•

•

•

In  October  2019,  we  entered  into  a  strategic  partnership  with  Avaya  Holdings  Corp.  ("Avaya"),  which  included  the  introduction  of  a  new
solution,  Avaya  Cloud  Office  by  RingCentral  ("ACO"),  to  be  marketed  and  sold  by  Avaya  and  its  subsidiaries.  We  launched  the  co-branded
solution in March 2020.

In December 2019, we entered into a strategic partnership agreement with Atos SE ("Atos") and its subsidiary, Unify Software and Solutions
GmbH & CO. KG ("Unify"), which included the introduction of a co-branded solution, Unified Office by RingCentral ("UO"), to be marketed
and sold as the UCaaS offering for the Atos Unify product family installed base. We launched the co-branded solution in September 2020.

In  July  2020,  we  entered  into  a  strategic  partnership  with  Alcatel-Lucent  Enterprise  ("ALE"),  which  includes  the  introduction  of  a  new  co-
branded solution to be marketed and sold as the UCaaS solution offering of ALE beginning in 2021.

In  November  2020,  we  entered  into  a  strategic  partnership  with  Vodafone  Group  Services  Limited  ("Vodafone"),  which  includes  a  new  co-
branded UCaaS and CCaaS solutions to be marketed and sold by Vodafone and its subsidiaries.

Our Solutions

Our cloud-based business communications, collaboration, and customer engagement solutions function across multiple locations and devices, including
smartphones, tablets, PCs and desk phones, allow for communication across multiple modes, including high-definition (“HD”) voice, video, SMS, messaging and
collaboration,  conferencing,  online  meetings,  and  fax.  Our  proprietary  solutions  enable  a  more  productive  and  dynamic  workforce  and  are  architected  using
industry  standards  to  meet  modern  business  communications  and  collaboration  requirements,  including  workforce  mobility,  “bring-your-own”  communications
device environments and multiple communications methods.

Our solutions are delivered using a highly available, and rapidly and easily scalable infrastructure, allowing our customers to add new users regardless of
where  they  are  located.  Our  solutions  are  generally  affordable,  requiring  little  to  no  upfront  infrastructure  hardware  costs  or  ongoing  maintenance  and  upgrade
costs commonly associated with on-premise systems and can be integrated with other existing communication systems.

We believe that our solutions go beyond the core functionality of existing on-premise communications solutions by providing additional key benefits that
address the changing requirements of business to allow business communications using voice, HD video web conferencing, SMS, team messaging, collaboration,
fax, and social media. The key benefits of our solutions include:

Location Independence.    Our cloud-based solutions are designed to be location independent. We seamlessly connect distributed and mobile
users, enabling employees  to communicate  with a single  identity  whether working from  a central  location,  a branch office,  on the  road, or at
home.

Global.       Our  RingCentral  Global  Office  capabilities  support  multinational  enterprise  workforces.  RingCentral  Global  Office  connects
multinational workforces globally, while reducing the complexity and high costs of maintaining multiple legacy private branch exchanges ("PBX
systems") with a single global cloud solution.

Device Independence.    Our solutions are designed to work with a broad range of devices, including smartphones, tablets, PCs, and desk phones,
enabling businesses to successfully implement a “bring-your-own” communications device strategy.

Instant Activation and Easy Account Management.    Our solutions are designed for rapid deployment and ease of management. Our intuitive
graphical  user  interfaces  allow  administrators  and  users  to  set  up  and  manage  their  business  communications  system  with  little  or  no  IT
expertise, training, or dedicated staffing.

Scalability.    Our cloud-based solutions scale easily and efficiently with the growth of our customers. Customers can add users, regardless of
their location, without having to purchase additional infrastructure hardware or software upgrades.

Lower Cost of Ownership.    We believe that our customers experience significantly lower cost of ownership compared to legacy on-premise
systems. Using our cloud-based solutions, our customers  can avoid the significant  upfront costs of infrastructure  hardware, software,  ongoing
maintenance and upgrade costs, and the need for dedicated and trained IT personnel to support these systems.

Seamless and Intuitive Integration with Other Applications.    Applications are proliferating within businesses of all sizes. Integration of these
business  applications  with  legacy  on-premise  systems  is  typically  complex  and  expensive,  which  limits  the  ability  of  businesses  to  leverage
cloud-based applications. Our platform provides seamless and intuitive integration with multiple popular cloud-based business applications such
as Microsoft  productivity  and CRM tools,  Google G-Suite, Salesforce  CRM, Oracle,  Okta, Zendesk, Box, and Workday,  as well as customer
lines-of business applications.

We  have  a  portfolio  of  cloud-based  offerings  that  are  subscription-based  and  made  available  at  different  monthly  rates,  varying  by  the  specific

functionalities, services, and number of users. We primarily generate revenues from the sale of subscriptions of our offerings, which include the following:

RingCentral Office.        RingCentral  Office,  our  flagship  solution,  provides  a  unified  experience  for  communication  and  collaboration  across  multiple
modes,  including  HD  voice,  video,  SMS,  messaging  and  collaboration,  conferencing,  online  meetings,  and  fax.  RingCentral  Office  offers  a  unified  Message,
Video, and Phone (MVP) experience on our global platform. Customers can extend RingCentral Office to support their multinational workforce in many countries
around the world. This subscription is designed primarily for businesses that require a communications solution, regardless of location, type of device, expertise,
size,  or  budget.  Businesses  are  able  to  seamlessly  connect  users  working  in  multiple  office  locations  on  smartphones,  tablets,  PCs  and  desk  phones.  We  sell
RingCentral Office in four editions: Essentials, Standard, Premium, and Ultimate. The features, capabilities and price per user increase from Essentials to Ultimate.
The solution capabilities  include high definition voice, call management, mobile applications, business SMS and MMS, fax, team messaging and collaboration,
audio/video/web  conferencing  capabilities,  out-of-the-box  integrations  with  other  cloud-based  business  applications,  and  business  analytics  and  reporting.  Our
platform  also  enables  customers  to  create,  develop,  and  deploy  custom  integrations  using  our  APIs.  RingCentral  Office  customers  also  have  available  to  them

others.  RingCentral  Rooms  and  Rooms  Connector  bring  a  cloud  web  conferencing  solution  to  meeting  rooms  and  meeting  spaces  that  have
dedicated video conferencing equipment such as monitors, speakers, microphones, and cameras, and support for large meetings and Webinars for
a monthly per license add-on fee.

Mobile-Centric Approach.        Our  solution  includes  smartphone  and  tablet  mobile  applications  that  customers  can  use  to  set  up  and  manage
company,  department,  and  user  settings  from  anywhere.  Our  applications  turn  iOS  and  Android  smartphones  and  tablets  into  business
communication devices. Users can change their personal settings instantly and communicate via voice, text, team messaging and collaboration,
HD video and web conferencing, and fax. Personal mobile devices are fully integrated into the customer’s cloud-based communication solution,
using the company’s numbers, and displaying one of the company’s caller ID for calls made through our mobile applications.

Easy Set-Up and Control.    Our user interfaces provide a consistent user experience across smartphones, tablets, PCs, and desk phones, making
it  intuitive  and  easy  for  our  customers  to  quickly  discover  and  use  our  solution  across  devices.  Among  other  capabilities,  administrators  can
specify  and  modify  company,  department,  user  settings,  auto-receptionist  settings,  call-handling,  and  routing  rules,  and  add,  change,  and
customize users and departments.

Flexible Call Routing.    Our solution includes an auto-attendant to easily customize call routing for the entire company, departments, groups, or
individual  employees.  It  includes  a  robust  suite  of  communication  management  options,  including  time  of  day,  caller  ID,  call  queuing,  and
sophisticated routing rules for complex call handling for the company, departments, groups, and individual employees.

Cloud-based  Business  Application  Integrations.        Our  solution  seamlessly  integrates  with  other  cloud-based  business  applications  such  as
Salesforce  CRM,  Google  Cloud,  Box,  Dropbox,  Office365,  Outlook,  Oracle,  Okta,  Zendesk,  Jira,  Asana,  and  others.  For  example,  our
integration with Salesforce CRM brings up customer records immediately based on inbound caller IDs, resulting in increased productivity and
efficiency. Our open platform is supported by APIs and software developers’ kits (“SDKs”) that allows developers to integrate our solution with
leading business applications or with other custom applications to customize their own business workflows.

Segment Reporting

Our organizational  structure is a single reportable segment. A discussion of the results of our operations is included in Part II, Item 7, "Management's
Discussion and Analysis of Financial Condition and Results of Operations", and in Part II, Item 8, "Consolidated Financial Statements and Supplementary Data" of
this Annual Report on Form 10-K, under Consolidated Financial Statements, which are incorporated herein by reference.

Our Customers

We have a diverse and growing customer base across a wide range of industries, including financial services, education, healthcare, legal services, real
estate,  retail,  technology,  insurance,  construction,  hospitality,  and  state  and  local  government,  among  others.  We  seek  to  establish  and  maintain  long-term
relationships with our customers. We do not have significant customer concentration and none of our customers accounted for more than 10% of total revenue for
the years ended December 31, 2020, 2019, and 2018. We believe that we will not have significant customer concentration in the future.

We sell our solutions to enterprise customers, and small and medium-sized businesses. We define a “customer” as a party that purchases or subscribes to
our  products  and  services  directly  or  indirectly  through  our  channel  partners.  We  continuously  expand  our  solution  offering  globally  and  believe  that  there  are
additional growth opportunities in international markets.

Marketing, Sales and Support

We  use  a  variety  of  marketing,  sales,  and  support  activities  to  generate  and  cultivate  ongoing  customer  demand  for  our  subscriptions,  acquire  new
customers,  and  engage  with  our  existing  customers.  We  sell  globally  through  both  direct  and  indirect  channels,  which  includes  resellers,  carriers,  and  strategic
partners. We provide onboarding implementation services to help our customers set up and configure their newly purchased communications system, as well as
ongoing self-service, phone support, online chat support, and training. We also closely track and monitor customer acquisition costs to assess how we are deploying
our marketing, sales, and customer support spending.

•

Marketing.    Our marketing efforts include search engine marketing, search engine optimization, affiliates, list buys, shared leads, content leads,
appointment setting, radio advertising, online display advertising, sports sponsorships, billboard advertising, tradeshows and events, and other
forms of demand generation. We track

and measure our marketing costs closely across all channels so that we can acquire customers in a cost-efficient manner.

•

Direct  Sales.        We  primarily  sell  our  solutions  and  subscriptions  through  direct  inbound  and  outbound  sales  efforts.  We  have  direct  sales
representatives located in the U.S. and internationally.

Indirect Sales.    Our indirect sales channel consists of global and regional networks of resellers and carriers including AT&T, Inc. ("AT&T"),
TELUS Communications Company ("TELUS"), BT Group plc ("BT"), and Vodafone. Our indirect sales channels help broaden the adoption of
our solutions without the need for a large direct sales force.

Customer  Support  and  Services.        While  our  intuitive  and  easy-to-use  user  interface  serves  to  reduce  our  customers’  need  for  support  and
services,  we  provide  online  chat  and  phone  customer  support,  as  well  as  post-sale  implementation  support,  as  an  option  to  help  customers
configure and use our solution. We track and measure our customer satisfaction and our support costs closely across all channels to provide a
high level of customer service in a cost-efficient manner.

Strategic Partnerships. We have strategic partnerships with several third parties including Avaya, Atos, and Alcatel Lucent Enterprise. These
partnerships enable us to leverage the sales force of our strategic partners to sell our services as well as access to their customer bases.

Research and Development

We  believe  that  continued  investment  in  research  and  development  is  critical  to  expanding  our  leadership  position  within  the  cloud-based  business
communications  and  collaboration  solutions  market  and  is  a  key  element  of  our  culture.  We  devote  the  majority  of  our  research  and  development  resources  to
software development. Our engineering team has significant experience in various disciplines related to our platform, such as voice, video, text, team messaging
and collaboration, mobile application development, IP networking and infrastructure, contact center, digital customer engagement, user experience, security, and
robust multi-tenant cloud-based system architecture.

Our  development  methodology,  in  combination  with  our  SaaS  delivery  model,  allows  us  to  provide  new  and  enhanced  capabilities  on  a  regular  basis.
Based on feedback from our customers and prospects and our review of the broader business communications and SaaS markets, we continuously develop new
functionality while maintaining and enhancing our existing solutions. We typically have multiple releases per year, where we constantly improve our solutions and
introduce new capabilities and features to make our customers’ workforce more productive and to build out the feature set required by larger and global enterprises.

As part of our strategy to expand our technological capabilities, we engage in strategic transactions from time to time. Such strategic acquisitions enable

us to complement our technology and skill sets and expand our solution reach.

Technology and Operations

Our  platforms  are  hosted  both  in  private  and  public  clouds.  Our  private  clouds  are  built  on  a  highly  scalable  and  flexible  infrastructure  comprised  of
commercially available hardware and software components. We believe that both hardware and software components of our platform can be replaced, upgraded or
added with minimal or no interruption in service. The system is designed to have no single point-of-failure.

Our private cloud is served from multiple data centers and third-party co-location facilities located in several cities in the United States and throughout the
world.  Our  data  centers  are  designed  to  host  mission-critical  computer  and  communications  systems  with  redundant,  fault-tolerant  subsystems,  and
compartmentalized security zones. We maintain a security program designed to ensure the security and integrity of customer data, protect against security threats or
data breaches, and prevent unauthorized access to our customers’ data. We limit access to on-demand servers and networks at our production and remote backup
facilities.

Intellectual Property

We  rely  on  a  combination  of  patent,  copyright,  and  trade  secret  laws  in  the  U.S.  and  other  jurisdictions,  as  well  as  license  agreements  and  other
contractual protections, to protect our proprietary technology. We also rely on a number of registered and unregistered trademarks to protect our brand. In addition,
we seek to protect our intellectual property rights by implementing a policy that requires our employees and independent contractors involved in the development
of intellectual property on our behalf to enter into agreements acknowledging that all works or other intellectual property generated or

9

Table of Contents

conceived by them on our behalf are our property, and assigning to us any rights, including intellectual property rights, that they may claim or otherwise have in
those works or property, to the extent allowable under applicable law.

Our  worldwide  intellectual  property  portfolio  includes  over  262  issued  patents,  which  expire  between  2022  and  2039,  and  over  57  patent  applications
pending examination in the U.S. and in foreign jurisdictions, all of which are related to U.S. applications. In general, our patents and patent applications apply to
certain aspects of our SaaS and mobile applications and underlying communications infrastructure. We are also a party to various license agreements with third
parties that typically grant us the right to use certain third-party technology in conjunction with our solutions and subscriptions.

Competition

The  market  for  business  communications  and  collaboration  solutions  is  very  large,  rapidly  evolving,  complex,  fragmented  and  defined  by  changing
technology,  and  customer  needs.  We  expect  competition  to  continue  to  increase  in  the  future.  We  believe  that  the  principal  competitive  factors  in  our  market
include:

•

•

•

•

•

•

•

•

•

product features and capabilities;

system reliability, availability, and performance;

speed and ease of activation, setup, and configuration;

ownership and control of the underlying technology;

open platform;

integration with mobile devices;

brand awareness and recognition;

simplicity of the pricing model; and

total cost of ownership.

We believe that we generally compete favorably on the basis of the factors listed above.

We face competition from a broad range of providers of business communications and collaboration solutions. Some of these competitors include:

•

•

•

•

•

•

•

traditional on-premise, hardware business communications providers such as Alcatel-Lucent Enterprise, Avaya Inc., Cisco Systems, Inc., Mitel
Networks  Corporation,  NEC  Corporation,  and  Siemens  Enterprise  Networks,  LLC,  any  of  which  may  now  or  in  the  future  also  host  their
solutions through the cloud;

software providers such as Microsoft Corporation and Cisco Systems, Inc. that generally license and/or host their software solutions, and their
resellers including major carriers and cable companies;

established  business  communications  providers  that  resell  on-premise  hardware,  software,  and  hosted  solutions,  such  as  AT&T, BT, Comcast
Corporation, Sprint Corporation, TELUS, Verizon Communications Inc., Vodafone Group Plc, and others, all of whom have significantly greater
resources than us and do now or may in the future also develop and/or host their own or other solutions through the cloud;

other  cloud  companies  such  as  8x8,  Inc.,  Amazon.com,  Inc.,  DialPad,  Inc.,  Fuze  Inc.,  StarBlue,  Inc.,  Intermedia.net,  Inc.,  J2  Global,  Inc.,
LogMeIn, Inc, Microsoft Corporation, Nextiva, Inc., Twilio Inc., Vonage Holdings Corp., West Corporation, and Zoom Video Communications,
Inc.;

video meeting and collaboration service providers such as Amazon.com, Inc., Apple Inc., Alphabet Inc. (Google G-Suite and Meet), Facebook,
Inc.,  Microsoft  Teams,  Slack  Technologies,  Inc.  (which  has  announced  it  will  be  acquired  by  saleforce.com,  inc.),  and  Zoom  Video
Communications, Inc.;

other large internet companies such as Alphabet Inc. (Google Voice), Facebook, Inc., Oracle Corporation, and salesforce.com, inc., any of which
might  launch  its  own  cloud-based  business  communication  services  or  acquire  other  cloud-based  business  communications  companies  in  the
future;

providers of communications platform as a service solutions and messaging software platforms with APIs such as Twilio Inc., Vonage Holding
Corp.,  and  Slack  Technologies,  Inc.,  on  which  customers  can  build  diverse  solutions  by  integrating  cloud  communications  into  business
applications;

10

•

•

contact center and customer relationship management providers such as Amazon.com, Inc., Aspect Software, Inc., Avaya Inc., Five9, Inc., NICE
InContact, Genesys Telecommunications Laboratories, Inc., Serenova, LLC (acquired by Lifesize, Inc.), Talkdesk, Inc., Vonage Holdings Corp.,
salesforce.com, inc., and Twilio Inc.; and

digital engagement vendors such as eGain Corporation, Lithium Technologies, LLC, LivePerson, Inc., SparkCentral Inc. (recently acquired by
Hootsuite Inc.), among others named above that may offer similar features.

Employees and Human Capital

We  believe  that  our  culture  and  our  workforce  are  critically  important  to  our  success.  Our  human  capital  resources  objectives  include  identifying,
recruiting, retaining, incentivizing and integrating our existing and new employees, advisors and consultants. We continuously invest in our global workforce by
seeking  to  create  a  diverse,  inclusive,  and  safe  work  environment  where  our  employees  can  learn,  innovate,  and  deliver  their  best.  We  are  committed  to  being
inclusive to enable our workforce and customers to succeed.

We  invest  in  developing  our  talent  and  creating  a  superior  team  member  experience  and  a  highly  engaged  workforce  to  remain  at  the  forefront  of
innovation and make RingCentral an employer of choice. We believe that our approach to talent development and innovation enables our team members to grow in
their current positions and build new skills. We provide virtual and in-person interactive learning courses across a broad range of categories such as leadership,
inclusion  and  diversity,  technical  and  compliance,  among  others.  We  have  regular  employee  surveys  that  allow  employees  to  voice  their  perceptions  of  the
Company and their work experience.

Our diversity and inclusion initiatives honor the unique background, identity, ethnicity, and perspectives of each individual in our organization and we are
committed  to  the  success  of  our  workforce  and  customers.  We  continue  to  drive  key  initiatives  in  talent  acquisition  and  diversity  to  focus  on  increasing  the
representation  of  women  and  underrepresented  groups  in  our  global  workforce.We  received  recognition  for  our  initiatives  in  the  area  of  diversity,  equity  and
inclusiveness,  wherein  our  CEO  was recognized  as  the  "Best  CEO  for  Women"  and  "Diversity"  by  Comparably.  We  actively  encourage  and  support  employee
resource groups like our LGBTQ+ group, Black employees group and Pan-Asian group, among others. We continue to further expand our efforts in the area of
diversity, equity and inclusion.

We face competition for highly skilled technical and other personnel with experience in our industry and locations where we maintain offices. We strive
to provide competitive pay, benefits, and services that help meet the varying needs of our employees. The principal purposes of our equity and cash incentive plans
are to attract, retain and reward personnel through the granting of stock-based and cash based compensation awards, in order to increase stockholder value and the
success of our Company by motivating such individuals to perform to the best of their abilities and achieve our objectives. We also provide access to a variety of
flexible health and wellness programs to our employees, which became increasingly critical in 2020 due to the COVID-19 pandemic.

As  of  December  31,  2020,  we  had  3,140  full-time  employees  located  in  13  countries.  As  of  December  31,  2020,  approximately  30%  of  our  full-time
employees  were  located  outside  of  the  United  States.  Our  geographic  diversification  enhances  our  ability  to  retain  and  attract  highly  skilled  talent  as  well  as
manage our headcount costs.

In certain countries in which we operate, we are subject to, and comply with, local labor law requirements, which may automatically make our employees
subject to industry-wide collective bargaining agreements. For instance, our employees in France are covered by the Syntec Collective Bargaining Agreement. We
are  not  subject  to  any  other  collective  bargaining  agreements.  We  believe  that  our  employee  relations  are  good,  and  we  have  never  experienced  any  work
stoppages.

Regulatory

As a  provider  of communication  services  over  the  Internet,  we are  subject  to regulation  in the U.S. by the FCC. Some of these  regulatory  obligations
include  contributing  to  the  Federal  Universal  Service  Fund,  Telecommunications  Relay  Service  Fund,  and  federal  programs  related  to  phone  number
administration;  providing  access  to  E-911  services;  protecting  customer  information;  and  porting  phone  numbers  upon  a  valid  customer  request.  We  are  also
required  to  pay  state  and  local  911  fees  and  contribute  to  state  universal  service  funds  in  those  states  that  assess  interconnected  Voice  over  Internet  Protocol
(“VoIP”) services. In addition, we have certified a wholly owned subsidiary as a competitive local exchange carrier in thirty-four states. This subsidiary, RCLEC,
is subject to the same FCC regulations applicable to telecommunications  companies, as well as regulation by the public utility commissions in states where the
subsidiary  provides  services.  Specific  regulations  vary  on  a  state-by-state  basis,  but  generally  include  the  requirement  for  our  subsidiary  to  register  or  seek
certification to provide its services, to file and update tariffs setting forth the terms, conditions and prices for our intrastate services and to comply with various
reporting, record-keeping, surcharge collection, and consumer protection requirements.

As we expand internationally, we will be subject to laws and regulations in the countries in which we offer our subscriptions. Regulatory treatment of
communications services over the Internet outside the U.S. varies from country to country, and may be more onerous than imposed on our subscriptions in the U.S.
In the United Kingdom, for example, our subscriptions are regulated by Ofcom, which, among other things, requires electronic communications services providers
such  as  our  company  to  provide  all  users  access  to  both  112  (EU-mandated)  and  999  (U.K.-mandated)  emergency  service  numbers  at  no  charge.  Similarly,  in
Canada, our subscriptions are regulated by the CRTC, which, among other things, imposes requirements like those in the U.S. related to the provision of E-911
services,  in  all  areas  of  Canada  where  the  wireline  incumbent  carrier  offers  such  911  services.  Our  regulatory  obligations  in  foreign  jurisdictions  could  have  a
material adverse effect on the use of our subscriptions in international locations.

In the course of providing our services, we collect, store, and process many types of data, including personal data. Moreover, our customers can use our
subscriptions to store contact and other personal or identifying information, and to process, transmit, receive, store, and retrieve a variety of communications and
messages, including information about their own customers and other contacts. Customers are able, and may be authorized under certain circumstances, to use our
subscriptions to transmit, receive, and/or store personal information.

There are a number of federal, state, local, and foreign laws and regulations, such as the European Union's General Data Protection Regulation ("GDPR")
and  the  recently  enacted  California  Consumer  Privacy  Act,  as  well  as  contractual  obligations  and  industry  standards,  that  provide  for  certain  obligations  and
restrictions  with  respect  to  data  privacy  and  security,  and  the  collection,  storage,  retention,  protection,  use,  processing,  transmission,  sharing,  disclosure,  and
protection of personal information and other customer data. We expect that with the expansion of our Global Office solution and sales of our services into new
countries, we will become subject to additional data privacy regulations in other countries throughout the world. The scope of these obligations and restrictions is
changing, subject to differing interpretations, and may be inconsistent among countries or conflict with other rules, and their status remains uncertain.

As Internet commerce and communication technologies continue to evolve, thereby increasing online service providers’ and network users’ capacity to
collect,  store,  retain,  protect,  use,  process,  and  transmit  large  volumes  of  personal  information,  increasingly  restrictive  regulation  by  federal,  state,  or  foreign
agencies becomes more likely.

Regulations that do not directly apply to our business, but which do apply to our customers and partners, can also impact our business. As we expand our
business, addressing  customer  and  partner  requirements  in new jurisdictions  and new verticals  often  requires  investment  on our part  to address  regulations  that
apply to our customers. Globally, these regulations continue to be introduced and to change over time. Such regulations can impact our ability to offer services to
various customer segments, and our cost to deliver our services.

See the section entitled “Risk Factors” for more information.

ITEM 1A. RISK FACTORS

This Report contains forward-looking statements that are subject to risks and uncertainties that could cause actual results to differ materially from those
projected. These risks and uncertainties include, but are not limited to, the risk factors set forth below. The risks and uncertainties described in this Report are not
the only ones we face. Additional risks and uncertainties not presently known to us or that we currently believe are immaterial may also affect our business. If any
of  these  known  or  unknown  risks  or  uncertainties  actually  occurs  and  have  a  material  adverse  effect  on  us,  our  business,  financial  condition  and  results  of
operations could be seriously harmed. In addition, the impacts of the COVID-19 pandemic and any worsening of the economic environment may exacerbate the
risks  described  below,  any  of  which  could  have  a  material  impact  on  us.  This  situation  is  changing  rapidly  and  additional  impacts  may  arise  that  we  are  not
currently aware of.

Summary Risk Factors

An investment in our Class A Common Stock involves a high degree of risk, and the following is a summary of key risk factors when considering an

investment. You should read this summary together with the more detailed description of each risk factor contained in the subheadings further below.

•

We have incurred significant losses and negative cash flows in the past and anticipate continuing to incur losses for at least the foreseeable future,
and we may therefore not be able to achieve or sustain profitability in the future.
Our quarterly and annual results of operations have fluctuated in the past and may continue to do so in the future. As a result, we may fail to meet
or to exceed the expectations of research analysts or investors, which could cause our stock price to fluctuate.
Our rapid growth and the quickly changing markets in which we operate make it difficult to evaluate our current business and future prospects,
which may increase the risk of investing in our stock.
Our future operating results will rely in part upon the successful execution of our strategic partnerships with Avaya, Atos/Unify, Alcatel-Lucent
Enterprise, Vodafone and others, which may not be successful.
We face intense competition in our markets and may lack sufficient financial or other resources to compete successfully.
We rely and may in the future rely significantly on our strategic partners, resellers, and carriers to sell our subscriptions; our failure to effectively
develop, manage, and maintain our indirect sales channels could materially and adversely affect our revenues.
To deliver our subscriptions, we rely on third parties for our network connectivity and for certain of the features in our subscriptions.
Interruptions  or  delays  in  service  from  our  third-party  data  center  hosting  facilities  and  co-location  facilities  could  impair  the  delivery  of  our
subscriptions, require us to issue credits or pay penalties and harm our business.
Failures  in  Internet  infrastructure  or  interference  with  broadband  access  could  cause  current  or  potential  users  to  believe  that  our  systems  are
unreliable, possibly leading our customers to switch to our competitors or to avoid using our subscriptions.
A cyber-attack,  information security breach or denial of service event could delay or interrupt service to our customers, harm our reputation, or
subject us to significant liability.
Increased customer turnover, or costs we incur to retain and upsell our customers, could materially and adversely affect our financial performance.
If we are unable to attract new customers to our subscriptions or upsell to those customers on a cost-effective basis, our business will be materially
and adversely affected.
The dual class structure of our common stock as contained in our charter documents has the effect of concentrating voting control with a limited
number of stockholders that held our stock prior to our initial public offering, including our founders and our executive officers, employees and
directors and their affiliates, and venture capital investors, and limiting other stockholders’ ability to influence corporate matters.

Risks Related to Our Business and Our Industry

We have incurred significant losses and negative cash flows in the past and anticipate continuing to incur losses for at least the foreseeable future, and we may
therefore not be able to achieve or sustain profitability in the future.

We have incurred substantial net losses since our inception. Over the past few years, we have spent considerable amounts of time and money to develop
new business communications solutions and enhanced versions of our existing business communications solutions to position us for future growth. Additionally,
we have incurred substantial losses and expended significant resources upfront to market, promote and sell our solutions and expect to continue to do so in the
future. We also

13

Table of Contents

expect to continue to invest for future growth, including for advertising, customer acquisition, technology infrastructure, storage capacity, services development
and international expansion. In addition, as a public company, we incur significant accounting, legal, and other expenses.

We  expect  to  continue  to  incur  losses  for  at  least  the  foreseeable  future  and  will  have  to  generate  and  sustain  increased  revenues  to  achieve  future
profitability. Achieving profitability will require us to increase revenues, manage our cost structure, and avoid significant liabilities. Revenue growth may slow,
revenues may decline, or we may incur significant losses in the future for a number of possible reasons, including general macroeconomic conditions, increasing
competition (including competitive pricing pressures), a decrease in the growth of the markets in which we compete, in particular the SaaS market, or if we fail for
any reason to continue to capitalize on growth opportunities. Additionally, we may encounter unforeseen operating expenses, difficulties, complications, delays,
service delivery, and quality problems and other unknown factors that may result in losses in future periods. If these losses exceed our expectations or our revenue
growth expectations are not met in future periods, our financial performance will be harmed and our stock price could be volatile or decline.

Our quarterly and annual results of operations have fluctuated in the past and may continue to do so in the future. As a result, we may fail to meet or to exceed
the expectations of research analysts or investors, which could cause our stock price to fluctuate.

Our quarterly and annual results of operations have varied historically from period to period, and we expect that they will continue to fluctuate due to a

variety of factors, many of which are outside of our control, including:

•

our ability to retain existing customers, resellers, and carriers, and expand our existing customers’ user base, and attract new customers;

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

our ability to introduce new solutions;

the actions of our competitors, including pricing changes or the introduction of new solutions;

our ability to effectively manage our growth;

our ability to successfully penetrate the market for larger businesses;

the mix of annual and multi-year subscriptions at any given time;

the timing, cost, and effectiveness of our advertising and marketing efforts;

the timing, operating cost, and capital expenditures related to the operation, maintenance and expansion of our business;

our ability to successfully and timely execute on, integrate, and realize the benefits of any acquisition, investment, strategic partnership, or other
strategic transaction or partnership we may make or undertake;

service outages or actual or perceived information security breaches and any related impact on our reputation;

our ability to accurately forecast revenues and appropriately plan our expenses;

our ability to realize our deferred tax assets;

costs associated with defending and resolving intellectual property infringement and other claims;

changes in tax laws, regulations, or accounting rules;

the timing and cost of developing or acquiring technologies, services or businesses, and our ability to successfully manage any such acquisitions;

the impact of foreign currencies on our business as we continue to expand our business internationally; and

the impact of worldwide economic, political, industry, and market conditions, including the continued effects of the global outbreak of COVID-
19.

The extent to which the global COVID-19 pandemic continues to impact our results will depend on future developments, which are uncertain and cannot
be fully predicted, including the duration of the pandemic, travel restrictions and social distancing in the U.S. and other countries, business closures or business
disruptions and the effectiveness of actions taken by governments and private businesses to attempt to contain and treat the disease. Any prolonged shutdown of a
significant portion of global economic activity or downturn in the global economy, along with any adverse effects on industries in which our customers operate,
could materially and adversely impact our business, results of operations and financial condition.

14

Table of Contents

Any one of the factors above, or the cumulative effect of some or all of the factors referred to above, may result in significant fluctuations in our quarterly
and annual results of operations. This variability and unpredictability could result in our failure to meet our publicly announced guidance or the expectations of
securities analysts or investors for any period, which could cause our stock price to decline. In addition, a significant percentage of our operating expenses is fixed
in nature and is based on forecasted revenues trends. Accordingly, in the event of revenue shortfalls, we may not be able to mitigate the negative impact on net
income (loss) and margins in the short term. If we fail to meet or exceed the expectations of research analysts or investors, the market price of our shares could fall
substantially, and we could face costly lawsuits, including securities class-action suits.

The global COVID-19 pandemic could harm our business, financial condition and results of operations.

In December 2019, a novel coronavirus, COVID-19 was reported in China and, in March 2020, the World Health Organization declared it a pandemic.
This  contagious  disease  outbreak  has  continued  to  spread  across  the  globe  and  is  impacting  worldwide  economic  activity  and  financial  markets.  In  light  of  the
uncertain and rapidly evolving situation relating to the spread of COVID-19, we have taken precautionary measures intended to minimize the risk of the virus to
our employees, our customers, and the communities in which we operate, which could negatively impact our business. We are, with certain exceptions, requiring
all employees around the globe to work remotely and have closed all of our offices. We have also suspended all non-essential travel worldwide for our employees.
While we have a distributed workforce and our employees are accustomed to working remotely or working with other remote employees, our workforce is not fully
remote.  Our employees  travel  frequently  to establish  and maintain  relationships  with one another, our customers  and prospective  customers,  resellers  and other
channel partners, and investors. Although we continue to monitor the situation and may adjust our current policies as more information and public health guidance
becomes available, temporarily suspending travel and restricting the ability to do business in person could negatively affect our customer success efforts, sales and
marketing efforts, challenge our ability to enter into customer and other commercial contracts in a timely manner and our ability to source, assess, negotiate, and
successfully implement and execute on, and realize the benefits of, acquisitions, investments, strategic partnerships and other strategic transactions, slow down our
recruiting efforts, or create operational or other challenges, any of which could harm our business, financial condition and results of operations. Furthermore, if a
natural disaster, power outage, connectivity issue, or other event occurred that impacted our employees’ ability to work remotely, it may be difficult or, in certain
cases, impossible, for us to continue our business for a substantial period of time. The increase in remote working may also result in privacy, security and fraud
concerns as well as increase our exposure to potential wage and hour issues. In addition, the COVID-19 pandemic has and will continue to disrupt the operations of
our customers, resellers and other channel partners, strategic partners, suppliers and other third-party providers for an indefinite period of time, including as a result
of travel restrictions and/or business shutdowns, all of which could continue to negatively impact our business, financial condition and results of operations. For
example,  to  address  customer  hardships,  in  vertical  markets  most  impacted  by  COVID-19,  such  as  retail  and  hospitality,  we  are  actively  working  with  some
customers to provide greater flexibility to manage challenges they are facing, but we cannot be assured that they will not reduce their number of users or terminate
their  subscriptions  altogether.  Furthermore,  some  governments  have  enacted  indefinite  orders  prohibiting  providers  of  telecommunications  services  from
discontinuing service for non-payment. This could adversely affect us by increasing the risk of non-payment by our customers. We may also incur further costs by
opting not to discontinue services to non-paying customers for reasons such as maintaining goodwill. More generally, the COVID-19 pandemic could continue to
adversely  affect  economies  and  financial  markets  globally,  continuing  the  economic  downturn,  which  could  decrease  technology  spending  and  continue  to
adversely affect demand for our solutions and harm our business. The full extent to which the COVID-19 pandemic may impact our financial condition or results
of operations remains uncertain.

Our rapid growth and the quickly changing markets in which we operate make it difficult to evaluate our current business and future prospects, which may
increase the risk of investing in our stock.

We have grown rapidly since 2009, when we introduced RingCentral Office, our current flagship product. We have encountered and expect to continue to
encounter risks and uncertainties frequently experienced by growing companies in rapidly changing markets. If our assumptions regarding these uncertainties are
incorrect  or  change  in  reaction  to  changes  in  our  markets,  or  if  we  do  not  manage  or  address  these  risks  successfully,  our  results  of  operations  could  differ
materially from our expectations, and our business could suffer.

Growth may place significant demands on our management and our infrastructure.

We continue to experience substantial growth in our business. This growth has placed and may continue to place significant demands on our management,

organizational structure, and our operational and financial infrastructure. As our

15

Table of Contents

operations  grow  in  size,  scope,  and  complexity,  we  will  need  to  increase  our  sales  and  marketing  efforts  and  add  additional  sales  and  marketing  personnel  in
various regions worldwide and improve and upgrade our systems and infrastructure to attract, service, and retain an increasing number of customers. For example,
we  expect  the  volume  of  simultaneous  calls  to  increase  significantly  as  our  customer  base  grows.  Our  network  hardware  and  software  may  not  be  able  to
accommodate  this  additional  simultaneous  call  volume.  The  expansion  of  our  systems  and  infrastructure  will  require  us  to  commit  substantial  financial,
operational, and technical resources in advance of an increase in the volume of business, with no assurance that the volume of business will increase. Any such
additional capital investments will increase our cost base.

Continued  growth  could  also  strain  our  ability  to  maintain  reliable  service  levels  for  our  customers,  resellers,  and  carriers  develop  and  improve  our
operational, financial and management controls, enhance our billing and reporting systems and procedures and recruit, train and retain highly skilled personnel. In
addition, our existing systems, processes, and controls may not prevent or detect all errors, omissions, or fraud. We may also experience difficulties in managing
improvements to our systems, processes, and controls or in connection with third-party software licensed to help us with such improvements. Any future growth,
particularly as we continue to expand internationally, would add complexity to our organization and require effective communication and coordination throughout
our organization. Additionally, our productivity and the quality of our solutions and services may be adversely affected if we do not integrate and train our new
employees quickly and effectively, particularly doing so remotely in the short term during the COVID-19 pandemic. If we fail to achieve the necessary level of
efficiency in our organization as we grow, our business, results of operations and financial condition could be materially and adversely affected.

Our future operating results will rely in part upon the successful execution of our strategic partnerships with Avaya, Atos/Unify, Alcatel-Lucent Enterprise,
Vodafone and others, which may not be successful.

A strategic partnership between two independent businesses is a complex, costly, and time-consuming process that will require significant management
attention  and  resources.  Realizing  the  benefits  of  our  strategic  partnerships,  particularly  our  relationships  with  Avaya  Holdings  Corp.  (“Avaya”)  and  its
subsidiaries, Atos SE (“Atos”) and its subsidiaries, including Unify Software and Solutions GmbH & CO. KG (“Unify”), and ALE Holding (“ALE Holding”) and
its subsidiaries, including ALE International (“ALE International” and together “ALE”) and Vodafone Business (“Vodafone”) and its subsidiaries, will depend in
part  on our ability  to  work with our  strategic  partners  to  develop,  market  and  sell  co-branded  solutions,  such as Avaya  Cloud Office  by RingCentral  (“ACO”),
Unify Office by RingCentral (“UO”), and Rainbow Office powered by RingCentral (“Rainbow Office”). Setting up and maintaining the operations and processes
of these strategic partnerships may cause us to incur significant costs, disrupt our business and, if implemented ineffectively, would limit the expected benefits to
us. In addition, the process of bringing ACO, UO, Rainbow Office and other co-branded solutions to market may take longer than anticipated or fail to materialize,
which could negate or reduce our anticipated benefits and revenue opportunities. In addition, we must be successful in marketing and selling ACO to realize the
benefits of our prepayment to Avaya of $345 million in our Class A Common Stock. The failure to successfully and timely implement and operate our strategic
partnerships could harm our ability to realize the anticipated benefits of these partnerships and could adversely affect our results of operations.

We face intense competition in our markets and may lack sufficient financial or other resources to compete successfully.

The cloud-based business communications and collaboration solutions industry is competitive, and we expect competition to increase in the future. We

face intense competition from other providers of business communications and collaboration systems and solutions.

Our  competitors  include  traditional  on-premise,  hardware  business  communications  providers  such  as  ALE,  Avaya  Inc.,  Cisco  Systems,  Inc.,  Mitel
Networks Corporation, NEC Corporation, Siemens Enterprise Networks, LLC, their resellers, and others, as well as companies such as Microsoft Corporation and
Cisco Systems, Inc., and their resellers that license their software. In addition, certain of our carriers and strategic partners, such as AT&T, BT, TELUS, Avaya,
Vodafone,  and  Atos  sell  or  are  expected  to  sell  our  solutions,  but  they  are  also  competitors  for  business  communications.  These  companies  have  significantly
greater  resources  than us and currently,  or may in the future,  develop and/or  host their  own or other  solutions  through the cloud. Such competitors  may not be
successful in or cease marketing and selling our solutions to their customers and ultimately be able to transition some or all of those customers onto their competing
solutions,  which  could  materially  and  adversely  affect  our  revenues  and  growth.  We  also  face  competition  from  other  cloud  companies  and  established
communications providers that resell on-premise hardware, software, and hosted solutions, such as 8x8, Inc., Amazon.com, Inc., Dialpad, Inc., Fuze, Inc., StarBlue,
Inc., Intermedia.net, Inc., J2 Global, Inc., LogMeIn, Inc, Microsoft Corporation, Nextiva, Inc., Twilio Inc., Vonage Holdings Corp., West Corporation, and Zoom
Video Communications, Inc., which has introduced a voice solution. Established communications providers, such as AT&T, Verizon Communications Inc., Sprint
Corporation and Comcast Corporation in the U.S., TELUS and others in Canada, and BT, Vodafone Group plc, and others in

16

Table of Contents

the U.K., that resell on-premise hardware, software, and hosted solutions, compete with us in business communications and currently, or may in the future, develop
and/or host their own cloud solutions. We may also face competition from other large Internet companies, such as Alphabet Inc. (Google Voice), Facebook, Inc.,
Oracle  Corporation,  and  salesforce.com,  inc.,  any  of  which  might  launch  its  own  cloud-based  business  communications  services  or  acquire  other  cloud-based
business communications companies in the future. We also compete against providers of communications platform as a service solutions and messaging software
platforms  with  APIs  such  as  Twilio  Inc.,  Vonage  Holdings  Corp.,  and  Slack  Technologies,  Inc.,  on which  customers  can  build  diverse  solutions  by integrating
cloud communications  into business applications.  We face competition  with respect  to this solution from  contact  center  and customer  relationship  management
providers such as Amazon.com, Inc., Aspect Software, Inc., Avaya Inc., Five9, Inc., NICE InContact, Genesys Telecommunications Laboratories, Inc., Serenova,
LLC,  Talkdesk,  Inc.,  Vonage  Holdings  Corp.,  salesforce.com,  inc.,  and  Twilio  Inc.  We  also  face  competition  from  digital  engagement  vendors  such  as  eGain
Corporation, Lithium Technologies, LLC, LivePerson, Inc., SparkCentral Inc., among others named above that may offer similar features.

Many  of  our  current  and  potential  competitors  have  longer  operating  histories,  significantly  greater  resources  and  name  recognition,  more  diversified
offerings, and larger customer bases than we have. As a result, these competitors may have greater credibility with our existing and potential customers and may be
better able to withstand an extended period of downward pricing pressure. In addition, certain of our competitors have partnered with, or been acquired by, and
may in the future partner with or acquire, other competitors to offer services, leveraging their collective competitive positions, which makes it more difficult to
compete  with  them  and  could  significantly  and  adversely  affect  our  results  of  operations.  Demand  for  our  platform  is  also  sensitive  to  price.  Many  factors,
including our marketing, user acquisition and technology costs, and our current and future competitors’ pricing and marketing strategies, can significantly affect
our pricing strategies. Our competitors may be able to adopt more aggressive pricing policies and devote greater resources to the development, promotion and sale
of their services than we can to ours. Some of these service providers have in the past and may choose in the future to sacrifice revenues in order to gain market
share by offering their services at lower prices or for free, or offering alternative pricing models, such as “freemium” pricing, in which a basic offering is provided
for  free  with  advanced  features  provided  for  a  fee,  on  the  services  they  offer.  Our  competitors  may  also  offer  bundled  service  arrangements  offering  a  more
complete service offering, despite the technical merits or advantages of our subscriptions. In addition, some of the commercially available solutions in the markets
in which we compete, such as video and web conferencing solutions of our competitors, including Zoom Video Communications and Microsoft Corporation, have
seen  dramatically  increased  adoption,  usage  and  publicity  in  connection  with  the  global  response  to  the  COVID-19  pandemic.  Competition  could  result  in  a
decrease to our prices, slow our growth, increase our customer turnover, reduce our sales, or decrease our market share.

We rely and may in the future rely significantly on our strategic partners, resellers, and carriers to sell our subscriptions; our failure to effectively develop,
manage, and maintain our indirect sales channels could materially and adversely affect our revenues.

Our  future  success  depends  on  our  continued  ability  to  establish  and  maintain  a  network  of  channel  relationships,  and  we  expect  that  we  will  need  to
expand  our  network  in  order  to  support  and  expand  our  historical  base  of  smaller  enterprises  as  well  as  attract  and  support  larger  customers  and  expand  into
international markets. An increasing portion of our revenues are derived from our network of sales agents and resellers, which we refer to collectively as resellers,
many of which sell or may in the future decide to sell their own services or services from other business communications providers. We generally do not have long-
term contracts with these resellers, and the loss of or reduction in sales through these third parties could materially reduce our revenues. Our competitors may in
some  cases  be  effective  in  causing  our  current  or  potential  resellers  to  favor  their  services  or  prevent  or  reduce  sales  of  our  subscriptions.  Furthermore,  while
AT&T,  BT,  TELUS,  Avaya,  Atos  (through  its  subsidiary  Unify),  ALE,  and  Vodafone  also  sell  our  solutions,  they  are  also  competitors  for  business
communications. These companies have significantly greater resources than us and currently, or may in the future, develop and/or host their own or other solutions
through  the  cloud.  Such  competitors  may  cease  marketing  or  selling  our  solutions  to  their  customers  and  ultimately  be  able  to  transition  some  or  all  of  those
customers onto their competing solutions, which could materially and adversely affect our revenues and growth. In this regard, AT&T launched a competing hosted
business communications solution in 2016, and new subscriptions for our solution sold by AT&T declined to an immaterial level in 2017 and into 2018. In August
2018, we entered into a revised agreement with AT&T, under which AT&T resumed reselling our solutions, and sales of our solutions by AT&T have increased as
a result, but there can be no guarantee that AT&T will not cease reselling our solutions in the future. We also recently entered into certain agreements for strategic
partnerships with Avaya, Atos, ALE, and Vodafone to sell certain of our solutions. Avaya introduced the ACO solution at the end of the first quarter of 2020, Atos
and Unify introduced the UO solution during the third quarter of 2020, and ALE is expected to introduce the Rainbow Office solution during the first quarter of
2021; however, there can be no guarantee that Avaya, Atos, Unify, ALE, Vodafone and/or any of their respective channel partners will be successful in marketing
or selling our solutions or that they will not cease marketing or selling our solutions in the future. If AT&T, Avaya, Atos, Unify, ALE, Vodafone and/or any of
their respective channel partners are not successful in

17

Table of Contents

marketing and selling our solutions or cease to market and sell our solutions, our revenues and growth could be significantly and adversely affected. If we fail to
maintain relationships with our resellers and other channel partners, carriers and strategic partners or fail to develop new and expanded relationships in existing or
new markets, or if our networks of indirect channel relationships are not successful in their sales efforts, sales of our subscriptions may decrease and our operating
results would suffer. Further, the ability of our resellers, carriers and strategic partners to market and sell our solutions could be adversely impacted by the COVID-
19 pandemic. In addition, we may not be successful in managing, training, and providing appropriate incentives to our existing resellers and other channel partners,
carriers and strategic partners, and they may not be able to commit adequate resources in order to successfully sell our solutions.

Recruiting and retaining qualified resellers and other channel partners and carriers in our network and training them in our technology and subscription
offerings requires significant  time and resources. To develop and expand our indirect sales channels, we must continue to scale and improve our processes and
procedures to support these channels, including investment in systems and training. Many resellers and other channel partners and carriers may not be willing to
invest the time and resources required to train their staff to effectively market our subscriptions.

To deliver our subscriptions, we rely on third parties for our network connectivity and for certain of the features in our subscriptions.

We currently use the infrastructure of third-party network service providers, including CenturyLink, Inc. and Bandwidth.com, Inc. in North America and
several others internationally, to deliver our subscriptions over their networks. Our third-party network service providers provide access to their Internet protocol
(“IP”) networks and public switched telephone networks, and provide call termination and origination services, including 911 emergency calling in the U.S. and
equivalent services internationally, and local number portability for our customers. We expect that we will continue to rely heavily on third-party network service
providers to provide these subscriptions for the foreseeable future.

Through our wholly-owned local exchange carrier subsidiary, RCLEC, Inc. (“RCLEC”), we also obtain certain connectivity and network services directly
from incumbent local exchange carriers (“ILECS”) and from other competitive local exchange carriers (“CLECs”) in certain geographic markets at lower prices
than we pay for such services through third-party network service providers. However, RCLEC also uses the infrastructure of third-party network service providers
to deliver its services and the ILECs may favor themselves and their affiliates may not provide network services to us at lower prices than we could obtain through
third-party CLECs, or at all. If we are unable to continue to reduce our pricing as a result of obtaining network services through our subsidiary, we may be forced
to rely on other third-party network service providers and be unable to effectively lower our cost of service. Historically, our reliance on third-party networks has
reduced our operating flexibility and ability to make timely service changes and control quality of service, and we expect that this will continue for the foreseeable
future. If any of these network service providers stop providing us with access to their infrastructure, fail to provide these services to us on a cost-effective basis or
at reasonable levels of quality and security, cease operations, or otherwise terminate these services, the delay caused by qualifying and switching to another third-
party network service provider, if one is available, could have a material adverse effect on our business and results of operations.

In addition, we currently use and may in the future use third-party service providers to deliver certain features of our subscriptions. For example, although
we introduced our own video and web conferencing solution in April 2020, we continue to rely in part on Zoom Video Communications for our HD video and web
conferencing and screen sharing features, Bandwidth.com for our texting capabilities, and NICE inContact, Inc. for our contact center capabilities. We do not or
may not in the future, have long-term contracts with certain of these third-party providers. If any of these service providers elects to stop providing us with access
to  their  services,  fails  to  provide  these  services  to  us  on  a  cost-effective  basis  or  at  reasonable  levels  of  quality  and  security,  ceases  operations,  or  otherwise
terminates  these  services,  the  delay  caused  by  qualifying  and  switching  to  another  third-party  service  provider,  if  one  is  available,  or  building  a  proprietary
replacement solution could have a material adverse effect on our business and results of operations.

Finally, if problems occur with any of these third-party network or service providers, it may cause errors or poor call quality in our subscriptions, and we
could  encounter  difficulty  identifying  the  source  of  the  problem.  These  third-party  network  or  service  providers  have  been  and  will  continue  to  be  adversely
impacted  or  overloaded  by  the  large  increase  in  traffic  caused  by  the  COVID-19  pandemic,  which  could  increase  our  exposure  to  damage  from  service
interruptions. The occurrence of errors or poor call quality in our subscriptions, whether caused by our systems or a third-party network or service provider, may
result  in  the  loss  of  our  existing  customers,  delay  or  loss  of  market  acceptance  of  our  subscriptions,  termination  of  our  relationships  and  agreements  with  our
resellers or carriers, or liability for failure to meet service level agreements, and may seriously harm our business and results of operations.

We rely on third-party software that may be difficult to replace or which could cause errors or failures of our subscriptions.

We  rely  on  software  licensed  from  certain  third  parties  in  order  to  offer  our  solutions.  In  some  cases,  we  integrate  third-party  licensed  software
components into our platform. This software may not continue to be available at reasonable prices or on commercially reasonable terms, or at all. Any loss of the
right  to  use  any  of  this  software  could  significantly  increase  our  expenses  and  otherwise  result  in  delays  in  the  provisioning  of  our  solutions  until  equivalent
technology is either developed by us, or, if available, is identified, obtained, and integrated. Any errors or defects in third-party software could result in errors or a
failure of our solutions, which could harm our business.

Interruptions or delays in service from our third-party data center hosting facilities and co-location facilities could impair the delivery of our subscriptions,
require us to issue credits or pay penalties and harm our business.

We currently serve our North American customers from geographically disparate data center hosting facilities in North America, where we lease space
from Equinix, Inc., and other providers, and we serve our European customers from third-party data center hosting facilities in Europe. We also use third-party co-
location  facilities  located  in various  international  regions  to  serve  our customers  in these  regions.  Certain  of our  solutions  are  hosted  by third  party  data  center
facilities  including  Amazon  Web  Services,  Inc.  (“AWS”),  NICE  inContact,  Inc.,  and  Google  Cloud  Platform.  In  addition,  RCLEC  uses  third-party  co-location
facilities to provide us with network services at several locations. Damage to, or failure of, these facilities, the communications network providers with whom we
or they contract, or with the systems by which our communications providers allocate capacity among their customers, including us, or software errors, have in the
past and could in the future result in interruptions in our services. Additionally, in connection with the addition of new data centers or expansion or consolidation of
our existing data center facilities, we may move or transfer our data and our customers’ data to other data centers. Despite precautions that we take during this
process, any unsuccessful data transfers may impair or cause disruptions in the delivery  of our subscriptions. Interruptions  in our subscriptions may reduce our
revenues, may require us to issue credits or pay penalties, subject us to claims and litigation, cause customers to terminate their subscriptions and adversely affect
our renewal rates and our ability to attract new customers. Our ability to attract and retain customers depends on our ability to provide customers with a highly
reliable subscription and even minor interruptions in our subscriptions could harm our brand and reputation and have a material adverse effect on our business.

As part of our current disaster recovery arrangements, our North American and European infrastructure and our North American and European customers’
data is currently replicated in near real-time at data center facilities in the U.S. and Europe, respectively. We do not control the operation of these facilities or of our
other  data  center  facilities  or  RCLEC’s  co-location  facilities,  and  they  are  vulnerable  to  damage  or  interruption  from  earthquakes,  floods,  fires,  power  loss,
telecommunications failures, and similar events. They may also be subject to human error or to break-ins, sabotage, acts of vandalism, and similar misconduct.

Despite precautions taken at these facilities, the occurrence of a natural disaster, public health crisis, such as the COVID-19 pandemic, human error, an act
of  terrorism  or  other  unanticipated  problems  at  these  facilities  could  result  in  lengthy  interruptions  in  our  subscriptions.  Even  with  the  disaster  recovery
arrangements in place, our subscriptions could be interrupted.

We may also be required to transfer our servers to new data center facilities in the event that we are unable to renew our leases on acceptable terms, if at
all, or the owners of the facilities decide to close their facilities, and we may incur significant costs and possible subscription interruption in connection with doing
so. In addition, any financial difficulties,  such as bankruptcy or foreclosure, faced by our third-party data center operators, or any of the service providers with
which we or they contract may have negative effects on our business, the nature and extent of which are difficult to predict. Additionally, if our data centers are
unable to keep up with our increasing needs for capacity, our ability to grow our business could be materially and adversely impacted.

Failures  in  Internet  infrastructure  or  interference  with  broadband  access  could  cause  current  or  potential  users  to  believe  that  our  systems  are  unreliable,
possibly leading our customers to switch to our competitors or to avoid using our subscriptions.

Unlike traditional communications services, our subscriptions depend on our customers’ high-speed broadband access to the Internet. Increasing numbers
of  users  and  increasing  bandwidth  requirements  may  degrade  the  performance  of  our  services  and  applications  due  to  capacity  constraints  and  other  Internet
infrastructure limitations. As our customer base grows and their usage of our services increases, we will be required to make additional investments in network
capacity  to  maintain  adequate  data  transmission  speeds,  the  availability  of  which  may  be  limited,  or  the  cost  of  which  may  be  on  terms  unacceptable  to  us.  If
adequate capacity is not available to us as our customers’ usage increases, our network may be unable to achieve or

19

Table of Contents

maintain sufficiently high reliability or performance. In addition, if Internet access service providers have outages or deteriorations in their quality of service, our
customers will not have access to our subscriptions or may experience a decrease in the quality of our services. Frequent or persistent interruptions could cause
current or potential users to believe that our systems or services are unreliable, leading them to switch to our competitors or to avoid our subscriptions, and could
permanently harm our reputation and brands.

In  addition,  users  who  access  our  subscriptions  and  applications  through  mobile  devices,  such  as  smartphones  and  tablets,  must  have  a  high-speed
connection, such as Wi-Fi, 3G, 4G, 5G, or LTE, to use our services and applications. Currently, this access is provided by companies that have significant and
increasing  market  power  in  the  broadband  and  Internet  access  marketplace,  including  incumbent  phone  companies,  cable  companies,  and  wireless  companies.
Some of these providers offer solutions and subscriptions that directly compete with our own offerings, which can potentially give them a competitive advantage.
Also, these providers could take measures that degrade, disrupt or increase the cost of user access to third-party services, including our subscriptions, by restricting
or  prohibiting  the  use  of  their  infrastructure  to  support  or  facilitate  third-party  services  or  by  charging  increased  fees  to  third  parties  or  the  users  of  third-party
services, any of which would make our subscriptions less attractive to users, and reduce our revenues.

Further,  in  January  2018,  the  Federal  Communications  Commission  (the  “FCC”)  released  an  order  reclassifying  broadband  Internet  access  as  an
information  service,  subject  to  certain  provisions  of  Title  I  of  the  Communications  Act.  Among  other  things,  the  order  eliminates  rules  adopted  in  2015  that
prohibited broadband providers from blocking, impairing, or degrading access to legal content, applications, services, or non-harmful devices, or engaging in the
practice  of  paid  prioritization,  e.g.,  the  favoring  of  some  lawful  Internet  traffic  over  other  traffic  in  exchange  for  higher  payments.  The  order  was  contested  in
federal  court,  was  largely  affirmed  by a  three-judge  panel;  the  request  for  rehearing  was denied  and  the  parties  declined  to  appeal  the  decision  to  the  Supreme
Court.  A  number  of  states  have  enacted  or  are  considering  legislation  or  executive  actions  that  would  regulate  the  conduct  of  broadband  providers.  We  cannot
predict  whether  the  FCC order  or  state  initiatives  will  be modified,  overturned,  or  vacated  by legal  action  of  the  court,  federal  or  state  legislation,  or  the  FCC.
Under the new FCC rules, broadband Internet access providers may be able to charge web-based services such as ours for priority access to customers, which could
result in increased costs and a loss of existing users, impair our ability to attract new users, and materially and adversely affect our business and opportunities for
growth.

Interruptions in our services caused by undetected errors, failures, or bugs in our subscriptions could harm our reputation, result in significant costs to us, and
impair our ability to sell our subscriptions.

Our subscriptions may have errors or defects that customers identify after they begin using them that could result in unanticipated interruptions of service.
Internet-based  services  frequently  contain  undetected  errors  and  bugs  when  first  introduced  or  when  new  versions  or  enhancements  are  released.  While  the
substantial majority of our customers are small and medium-sized businesses, the use of our subscriptions in complicated, large-scale network environments may
increase our exposure to undetected errors, failures, or bugs in our subscriptions. Although we test our subscriptions to detect and correct errors and defects before
their general release, we have, from time to time, experienced significant interruptions in our subscriptions as a result of such errors or defects and may experience
future interruptions of service if we fail to detect and correct these errors and defects. The costs incurred in correcting such defects or errors may be substantial and
could harm our results of operations. In addition, we rely on hardware purchased or leased and software licensed from third parties to offer our subscriptions.

Any defects in, or unavailability of, our or third-party software or hardware that cause interruptions of our subscriptions could, among other things:
•
•
•
•
•
•

cause a reduction in revenues or delay in market acceptance of our subscriptions;
require us to pay penalties or issue credits or refunds to our customers, resellers, or carriers, or expose us to claims for damages;
cause us to lose existing customers and make it more difficult to attract new customers;
divert our development resources or require us to make extensive changes to our software, which would increase our expenses and slow innovation;
increase our technical support costs; and
harm our reputation and brand.

20

Table of Contents

We rely on third parties, including third parties outside the U.S., for some of our software development, quality assurance, operations, and customer support.

We currently depend on various third parties for some of our software development efforts, quality assurance, operations, and customer support services.
Specifically, we outsource some of our software development and design, quality assurance, and operations activities to third-party contractors that have employees
and consultants located in St. Petersburg, Russia, Odessa, Ukraine, and Manila, the Philippines. In addition, we outsource a portion of our customer support, inside
sales  and  network  operation  control  functions  to  third-party  contractors  located  in  Manila,  the  Philippines.  Our  dependence  on  third-party  contractors  creates  a
number of risks, in particular, the risk that we may not maintain service quality, control, or effective management with respect to these business operations. These
third parties have been and will continue to be adversely impacted by the COVID-19 pandemic as a result of widespread illness and disruptions or restrictions on
employees’ ability to work, which may continue to affect their ability to perform satisfactorily or at all.

In  addition,  recent  political  and  military  events  in  Ukraine,  poor  relations  between  the  U.S. and  Russia,  and  sanctions  by  the  U.S.  and  the  EU  against
Russia could have an adverse impact on our third-party software development and quality assurance operations in Ukraine and Russia. Additionally, we rely on
purchased  or  leased  hardware  and  software  licensed  from  third  parties  in  order  to  offer  our  subscriptions,  and  in  some  cases,  we  integrate  third-party  licensed
software components into our platform. Any errors or defects in third-party hardware or software could result in errors or a failure of our subscriptions which could
harm our business.

We anticipate that we will continue to depend on these and other third-party relationships in order to grow our business for the foreseeable future. If we
are  unsuccessful  in  maintaining  existing  and,  if  needed,  establishing  new  relationships  with  third  parties,  our  ability  to  efficiently  operate  existing  services  or
develop new services and provide adequate customer support could be impaired, and, as a result, our competitive position or our results of operations could suffer.

A cyber-attack, information security breach or denial of service event could delay or interrupt service to our customers, harm our reputation, or subject us to
significant liability.

Our  operations  depend  on  our  ability  to  protect  our  production  and  corporate  information  technology  services  from  interruption  or  damage  from
unauthorized entry, computer malware or other events beyond our control. We have, from time to time, been subject to communications fraud and cyber-attacks by
malicious actors, and denial of service events, and we may be subject to similar attacks in the future. We cannot assure you that our backup systems, regular data
backups, security controls and other procedures currently in place, or that may be in place in the future, will be adequate to prevent significant damage, system
failure, service outages, data breach, data loss, or increased charges from our technology vendors.

Also,  our  subscriptions  are  web-based.  The  amount  of  data  we  store  for  our  users  increases  as  our  business  grows.  We  host  services,  which  includes
hosting  customer  data,  both  in  co-located  data  centers  and  in  multiple  public  cloud  services.  Our  solutions  allow  users  to  store  files,  tasks,  calendar  events,
messages  and  other  data  indefinitely  on  our  services  or  as  may  be  directed  by  our  customers.  We  also  maintain  sensitive  data  related  to  our  technology  and
business, and that of our employees, strategic partners, and customers, including intellectual property, proprietary business information and personally identifiable
information (also called personal data) on our own systems and in multiple vendors’ cloud services. As a result of maintaining larger volumes of data and user files
and/or  as  a  result  of  our  continued  movement  up  market,  or  movement  into  new  customer  segments  and  acquisition  of  larger  and  more  recognized
customers, we may become more of a target for hackers, nation states and other malicious actors.

In addition, we use third-party vendors which, in some cases, have access to our data and our customers’ data. We employ layered security measures and
have a means of working with third parties who report vulnerabilities to us. Despite the implementation of security measures by us or our vendors, our computing
devices, infrastructure, or networks, or our vendors’ computing devices, infrastructure, or networks, may be vulnerable to hackers, computer viruses, worms, other
malicious  software  programs,  or  similar  disruptive  problems  that  are  caused  by  or  through  a  security  weakness  or  vulnerability  in  our  or  our  vendors’
infrastructure, network, or business practices or our or our vendors’ customers, employees, business partners, consultants, or other Internet users who attempt to
invade our or our vendors’ corporate and personal computers, tablets, mobile devices, software, data networks, or voice networks. If there is a security weakness or
vulnerability  in  our,  our  vendors’,  or  our  customers’  infrastructure,  networks,  or  business  practices  that  is  successfully  targeted,  we  could  face  increased  costs,
liability  claims,  including  contractual  liability  claims  relating  to  security  obligations  in  agreements  with  our  partners  and  our  customers,  fines,  claims,
investigations  and other  proceedings,  reduced  revenue,  or harm  to our reputation  or competitive  position.  In addition,  even if not targeted,  in strengthening  our
security  controls  or  in  remediating  security  vulnerabilities,  we  could  incur  increased  costs  and  capital  expenditures.  The  COVID-19  pandemic  is  generally
increasing the attack surface available to

criminals,  as  more  companies  and  individuals  work  online,  and  as  such,  the  risk  of  a  cybersecurity  incident  potentially  occurring,  and  our  investment  in  risk
mitigations against such an incident, is increasing. Also, cyber-attacks, including on the supply chain, appear to be increasing in sophistication. For example, while
we do not use SolarWinds products in our environment, we have evaluated our internal systems and networks and found no evidence of unauthorized access to
customer data as a result of the issue. We continue to investigate, including reaching out to our third party supply chain partners to understand whether there have
been impacts to vendors in our supply chain. We continue to monitor for insights to enhance our code review and security-by-design process to help prevent a
similar incident. We cannot provide assurances that our preventative efforts will be successful.

Further, in some cases we do not have in place disaster recovery facilities for certain ancillary services, such as email delivery of messages. We rely on
encryption and authentication technology to ensure secure transmission of and access to confidential information, including customer credit card numbers, debit
card numbers, direct debit information, customer communications, and files uploaded by our customers. Advances in computer capabilities, new discoveries in the
field  of  cryptography,  discovery  of  software  bugs  or  vulnerabilities,  discovery  of  hardware  bugs  or  vulnerabilities,  social  engineering  activities,  or  other
developments may result in a compromise or breach of the technology we use to protect our data and our customer data, or of the data itself.

Additionally,  third  parties  have  attempted  in  the  past,  and  may  attempt  in  the  future,  to  induce  domestic  and  international  employees,  consultants,  or
customers into disclosing sensitive information, such as user names, provisioning data, customer proprietary network information (“CPNI”) or other information in
order  to  gain  access  to  our  customers’  user  accounts  or  data,  or  to  our  data.  CPNI  includes  information  such  as  the  phone  numbers  called  by  a  customer,  the
frequency, duration, and timing of such calls, and any services purchased by the consumer, such as call waiting, call forwarding, and caller ID, in addition to other
information  that  may  appear  on  a  customer’s  bill.  Third  parties  may  also  attempt  to  induce  employees,  consultants,  or  customers  into  disclosing  sensitive
information regarding our intellectual property and other confidential business information, our customers, the customer information we hold, or our information
technology systems. In addition, the techniques used to obtain unauthorized access, to perform hacking, phishing and social engineering, or to sabotage systems
change  and  evolve  frequently  and  may  not  be  recognized  until  launched  against  a  target,  may  be  new  and  previously  unknown  or  little-known,  or  may  not  be
detected  or  understood  until  well  after  such  actions  are  conducted.  We  may  be  unable  to  anticipate  these  techniques  or  to  implement  adequate  preventative
measures, and any security breach or other incident may take longer than expected to remediate or otherwise address. Any system failure or security breach that
causes  interruptions  or  data  loss  in  our  operations  or  in  the  computer  systems  of  our  customers  or  leads  to  the  misappropriation  of  our  or  our  customers’
confidential or personal information could result in significant liability to us, loss of our intellectual property, cause our subscriptions to be perceived as not being
secure, cause considerable harm to us and our reputation (including requiring notification to customers, regulators, or the media), and deter current and potential
customers from using our subscriptions. Any of these events could have a material adverse effect on our business, results of operations, and financial condition.

It is critical to our business that our information and our employees’, strategic partners’, and customers’ sensitive information remains secure and that our
customers perceive that this information is secure. An information security incident could result in unauthorized access to, loss of, or unauthorized disclosure of
such information. A cybersecurity breach could expose us to litigation, indemnity obligations, government investigations, contractual liability, and other possible
liabilities. Additionally, a cyber-attack or other information security incident, whether actual or perceived, could result in negative publicity, which could harm our
reputation  and  reduce  our  customers’  confidence  in  the  effectiveness  of  our  solutions,  which  could  materially  and  adversely  affect  our  business  and  operating
results. A breach of our security systems could also expose us to increased costs, including remediation costs, disruption of operations, or increased cybersecurity
protection costs, that may have a material adverse effect on our business. In addition, a cybersecurity breach of our customers’ systems can also result in exposure
of their authentication credentials, unauthorized access to their accounts, exposure of their account information and data (including CPNI), and fraudulent calls on
their  accounts,  which  can  subsequently  have  similar  actual  or  perceived  impacts  to  us  as  described  above.  A  cybersecurity  breach  of  our  partners’  or  vendors’
systems can result in similar actual or perceived impacts.

While we maintain cybersecurity insurance, our insurance may be insufficient to cover all liabilities incurred by privacy or security incidents. We also
cannot  be  certain  that  our  insurance  coverage  will  be adequate  for  data  handling  or  data  security  liabilities  actually  incurred,  that  insurance  will continue  to be
available to us on economically reasonable terms, or at all, or that an 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,  including  our  financial  condition,  operating
results, and reputation.

Laws, regulations, and enforcement actions relating to security and privacy of information continue to evolve. We have incurred and expect to continue to
incur significant expenses to prevent security incidents. It is possible that, in order to support changes to applicable laws and to support our expansion of sales into
new geographic areas or into new industry segments, we will need to increase or change our cybersecurity systems and expenditures. Further, it is possible that
changes to laws and regulations relating to security and privacy may make it more expensive to operate in certain jurisdictions and may increase the risk of our
non-compliance with such changing laws and regulations.

Potential problems with our information systems could interfere with our business and operations.

We  rely  on  our  information  systems  and  those  of  third  parties  for  processing  customer  orders,  distribution  of  our  subscriptions,  billing  our  customers,
processing credit card transactions, customer relationship management, supporting financial planning and analysis, accounting functions and financial statement
preparation,  and  otherwise  running  our  business.  Information  systems  may  experience  interruptions,  including  interruptions  of  related  services  from  third-party
providers,  which  may  be  beyond  our  control.  Such  business  interruptions  could  cause  us  to  fail  to  meet  customer  requirements.  All  information  systems,  both
internal  and  external,  are  potentially  vulnerable  to  damage  or  interruption  from  a  variety  of  sources,  including  without  limitation,  computer  viruses,  security
breaches,  energy  blackouts,  natural  disasters,  terrorism,  war,  telecommunication  failures,  employee  or  other  theft,  and  third-party  provider  failures.  In  addition,
since  telecommunications  billing  is  inherently  complex  and  requires  highly  sophisticated  information  systems  to  administer,  our  internally  developed  billing
system,  which  is  currently  being  implemented,  may  experience  errors  or  we  may  improperly  operate  the  system,  which  could  result  in  the  system  incorrectly
calculating the fees owed by our customers for our subscriptions or related taxes and administrative fees. Any such errors in our customer billing could harm our
reputation and cause us to violate truth in billing laws and regulations. Our current internally developed billing system requires us to process an increasing number
of invoices manually, which could result in billing errors. Any errors or disruption in our information systems and those of the third parties upon which we rely
could  have  a  significant  impact  on  our  business.  In  addition,  we  may  implement  further  and  enhanced  information  systems  in  the  future  to  meet  the  demands
resulting from our growth and to provide additional capabilities and functionality. The implementation of new systems and enhancements is frequently disruptive
to the underlying business of an enterprise, and can be time-consuming and expensive, increase management responsibilities, and divert management attention.

We depend largely on the continued services of our senior management and other highly-skilled employees, and if we are unable to hire, retain, manage and
motivate our employees, we may not be able to grow effectively and our business, results of operations and financial condition could be adversely affected.

Our  future  performance  depends  on  the  continued  services  and  contributions  of  our  senior  management  and  other  key  employees  to  execute  on  our
business  plan,  and  to  identify  and  pursue  opportunities  and  services  innovations.  The  loss  of  services  of  senior  management  or  other  key  employees  could
significantly delay or prevent the achievement of our development and strategic objectives. In particular, we depend to a considerable degree on the vision, skills,
experience, and effort of our co-founder, Chairman and Chief Executive Officer, Vladimir Shmunis. None of our executive officers or other senior management
personnel is bound by a written employment agreement and any of them may therefore terminate employment with us at any time with no advance notice. The
replacement of any of these senior management personnel would likely involve significant time and costs, and such loss could significantly delay or prevent the
achievement  of  our  business  objectives.  The  loss  of  the  services  of  our  senior  management  or  other  key  employees  for  any  reason  could  adversely  affect  our
business, financial condition, or results of operations.

Our future success also depends on our ability to continue to attract and retain highly skilled personnel. We believe that there is, and will continue to be,
intense  competition  for  highly  skilled  technical  and  other  personnel  with  experience  in  our  industry  in  the  San  Francisco  Bay  Area,  where  our  headquarters  is
located,  in  Denver,  Colorado,  where  our  U.S.  sales  and  customer  support  office  and  our  network  operations  center  is  located,  and  in  other  locations  where  we
maintain  offices.  In  addition,  changes  to  U.S.  immigration  policies,  particularly  to  H-1B  and  other  visa  programs,  and  restrictions  on  travel  (including  but  not
limited to current travel restrictions due to the COVID-19 pandemic) could restrain the flow of technical and professional talent into the U.S. and may inhibit our
ability  to  hire  qualified  personnel.  We  must  provide  competitive  compensation  packages  and  a  high-quality  work  environment  to  hire,  retain,  and  motivate
employees. If we are unable to retain and motivate our existing employees and attract qualified personnel to fill key positions, we may be unable to manage our
business effectively, including the development, marketing, and sale of existing and new subscriptions, which could have a material adverse effect on our business,
financial condition, and results of operations. To the extent we hire personnel from competitors, we may be subject to allegations that they have been improperly
solicited or divulged proprietary or other confidential information. Volatility in, or lack of performance of, our stock price may also affect our ability to attract and
retain key personnel.

Increased customer turnover, or costs we incur to retain and upsell our customers, could materially and adversely affect our financial performance.

Although we have entered into long-term contracts with larger customers, those customers who do not have long-term contracts with us may terminate
their subscriptions at any time without penalty or early termination charges. We cannot accurately predict the rate of customer terminations or average monthly
subscription  cancellations  or  failures  to  renew,  which  we  refer  to  as  turnover.  Our  customers  with  subscription  agreements  have  no  obligation  to  renew  their
subscriptions  for  our  service  after  the  expiration  of  their  initial  subscription  period,  which  is  typically  between  one  and  three  years.  In  the  event  that  these
customers do renew their subscriptions, they may choose to renew for fewer users, shorter contract lengths, or for a less expensive subscription plan or edition. We
cannot predict the renewal rates for customers that have entered into subscription contracts with us.

Customer turnover, as well as reductions in the number of users for which a customer subscribes, each could have a significant impact on our results of
operations, as does the cost we incur in our efforts to retain our customers and encourage them to upgrade their subscriptions and increase their number of users.
Our  turnover  rate  could  increase  in  the  future  if  customers  are  not  satisfied  with  our  subscriptions,  the  value  proposition  of  our  subscriptions  or  our  ability  to
otherwise meet their needs and expectations. Turnover and reductions in the number of users for whom a customer subscribes may also increase due to factors
beyond  our  control,  including  the  failure  or  unwillingness  of  customers  to  pay  their  monthly  subscription  fees  due  to  financial  constraints  and  the  impact  of  a
slowing  economy.  In  addition,  any  economic  downturn  resulting  from  the  COVID-19  pandemic  could  cause  financial  hardship  for  our  customers,  decrease
technology spending and materially and negatively impact our customers’ willingness to enter into or renew subscriptions with us, or cause our customers to seek a
decrease in the number of users or solutions for which they subscribe. For example, to address customer hardships, in vertical markets most impacted by COVID-
19, such as retail and hospitality, we are actively working with some customers to provide greater flexibility to manage challenges they are facing, but we cannot be
assured that they will not reduce their number of users or terminate their subscriptions altogether. Due to turnover and reductions in the number of users for whom
a  customer  subscribes,  we  must  acquire  new  customers,  or  acquire  new  users  within  our  existing  customer  base,  on  an  ongoing  basis  simply  to  maintain  our
existing level of customers and revenues. If a significant number of customers terminate, reduce, or fail to renew their subscriptions, we may be required to incur
significantly higher marketing expenditures than we currently anticipate in order to increase the number of new customers or to upsell existing customers, and such
additional marketing expenditures could harm our business and results of operations.

Our future success also depends in part on our ability to sell additional subscriptions and additional functionalities  to our current customers. This may
require increasingly sophisticated and more costly sales efforts and a longer sales cycle. Any increase in the costs necessary to upgrade, expand and retain existing
customers  could  materially  and  adversely  affect  our  financial  performance.  If  our  efforts  to  convince  customers  to  add  users  and,  in  the  future,  to  purchase
additional  functionalities  are  not  successful,  our  business  may  suffer.  In  addition,  such  increased  costs  could  cause  us  to  increase  our  subscription  rates,  which
could increase our turnover rate.

If  we  are  unable  to  attract  new  customers  to  our  subscriptions  or  upsell  to  those  customers  on  a  cost-effective  basis,  our  business  will  be  materially  and
adversely affected.

In  order  to  grow  our  business,  we  must  continue  to  attract  new  customers  and  expand  the  number  of  users  in,  and  services  provided  to,  our  existing
customer base on a cost-effective basis. We use and periodically adjust the mix of advertising and marketing programs to promote our subscriptions. Significant
increases in the pricing of one or more of our advertising channels would increase our advertising costs or may cause us to choose less expensive and perhaps less
effective channels to promote our subscriptions. As we add to or change the mix of our advertising and marketing strategies, we may need to expand into channels
with  significantly  higher  costs  than  our  current  programs,  which  could  materially  and  adversely  affect  our  results  of  operations.  In  addition,  the  COVID-19
pandemic and global slowdown of economic activity has and will continue to disrupt our sales channels and our ability to attract new customers, which may require
us to adjust our advertising and marketing programs or make further investments in these programs. We will incur advertising and marketing expenses in advance
of when we anticipate recognizing any revenues generated by such expenses, and we may fail to otherwise experience an increase in revenues or brand awareness
as a result of such expenditures. We have made in the past, and may make in the future, significant expenditures and investments in new advertising campaigns,
and  we  cannot  assure  you  that  any  such  investments  will  lead  to  the  cost-effective  acquisition  of  additional  customers.  If  we  are  unable  to  maintain  effective
advertising  programs,  our  ability  to  attract  new  customers  could  be  materially  and  adversely  affected,  our  advertising  and  marketing  expenses  could  increase
substantially, and our results of operations may suffer.

Some  of  our  potential  customers  learn  about  us  through  leading  search  engines,  such  as  Google,  Yahoo!,  and  Bing.  While  we  employ  search  engine
optimization and search engine marketing strategies, our ability to maintain and increase the number of visitors directed to our website is not entirely within our
control. If search engine companies modify their search algorithms in a manner that reduces the prominence of our listing, or if our competitors’ search engine
optimization efforts are more successful than ours, or if search engine companies restrict or prohibit us from using their services, fewer potential customers may
click through to our website. In addition, the cost of purchased listings has increased in the past and may increase in the future. A decrease in website traffic or an
increase in search costs could materially and adversely affect our customer acquisition efforts and our results of operations.

As a result of the COVID-19 pandemic, there has been an increase in the rate of adoption of video and web conferencing solutions; however, we cannot

predict whether or for how long these patterns will continue.

A significant portion of our revenues today come from small and medium-sized businesses, which may have fewer financial resources to weather an economic
downturn.

A significant portion of our revenues today come from small and medium-sized businesses. These customers may be materially and adversely affected by
economic  downturns  to  a  greater  extent  than  larger,  more  established  businesses.  These  businesses  typically  have  more  limited  financial  resources,  including
capital-borrowing  capacity,  than  larger  entities.  The  COVID-19  pandemic  has  had  adverse  effects  on  economies  and  financial  markets  globally,  which  have
particularly impacted many small and medium sized businesses. Any economic downturn resulting from the COVID-19 pandemic and preventative measures taken
by governments  and private  business worldwide could decrease  technology  spending  and  adversely  affect  demand  for our offerings  and  harm  our business and
results of operations. Although the U.S. government and others throughout the world have taken steps to provide monetary and fiscal assistance to individuals and
businesses affected by the pandemic, it is unclear whether government actions will successfully avert or mitigate any economic downturn. As the majority of our
customers  pay  for  our  subscriptions  through  credit  and  debit  cards,  weakness  in  certain  segments  of  the  credit  markets  and  in  the  U.S.  and  global  economies
has  resulted  in  and  may  in  the  future  result  in  increased  numbers  of  rejected  credit  and  debit  card  payments,  which  could  materially  affect  our  business  by
increasing customer cancellations and impacting our ability to engage new small and medium-sized customers. If small and medium-sized businesses experience
financial hardship as a result of a weak economy, industry consolidation or for any other reason, the overall demand for our subscriptions could be materially and
adversely affected.

We face significant risks in our strategy to target medium-sized  and larger businesses for sales of our subscriptions and, if we do not manage these efforts
effectively, our business and results of operations could be materially and adversely affected.

Sales to medium-sized and larger businesses continue to grow in both absolute dollars and as a percentage of our total sales. As we continue to target
more of our sales efforts to medium-sized and larger businesses, we expect to incur higher costs and longer sales cycles and we may be less effective at predicting
when  we  will  complete  these  sales.  In  these  market  segments,  the  decision  to  purchase  our  subscriptions  generally  requires  the  approval  of  more  technical
personnel  and  management  levels  within  a  potential  customer’s  organization,  and  therefore,  these  types  of  sales  require  us to  invest  more  time  educating  these
potential customers about the benefits of our subscriptions. In addition, larger customers may demand more features, integration services, and customization, and
may require highly skilled sales and support personnel. Our investment in marketing our subscriptions to these potential customers may not be successful, which
could significantly and adversely affect our results of operations and our overall ability to grow our customer base. Furthermore, many medium-sized and larger
businesses that we target for sales may already purchase business communications solutions from our larger competitors. As a result of these factors, these sales
opportunities may require us to devote greater research and development resources and sales support to individual customers, and invest in hiring and retaining
highly  skilled  personnel,  resulting  in  increased  costs  and  could  likely  lengthen  our  typical  sales  cycle,  which  could  strain  our  sales  and  support  resources.
Moreover,  these  larger  transactions  may  require  us  to  delay  recognizing  the  associated  revenues  we  derive  from  these  customers  until  any  technical  or
implementation requirements have been met.

Support  for  smartphones  and  tablets  are  an  integral  part  of  our  solutions.  If  we  are  unable  to  develop  robust  mobile  applications  that  operate  on  mobile
platforms that our customers use, our business and results of operations could be materially and adversely affected.

Our solutions allow our customers to use and manage our cloud-based business communications solution on smart devices. As new smart devices and
operating  systems  are  released,  we  may  encounter  difficulties  supporting  these  devices  and  services,  and  we  may  need  to  devote  significant  resources  to  the
creation, support, and maintenance of our mobile applications.

25

Table of Contents

In  addition,  if  we  experience  difficulties  in  the  future  integrating  our  mobile  applications  into  smart  devices  or  if  problems  arise  with  our  relationships  with
providers  of mobile  operating  systems,  such as those of Apple Inc. or Alphabet  Inc. (the parent  company of Google Inc.), our future  growth and our results  of
operations could suffer.

If we are unable to develop, license, or acquire new services or applications on a timely and cost-effective basis, our business, financial condition, and results
of operations may be materially and adversely affected.

The  cloud-based  business  communications  industry  is  an  emerging  market  that  is  characterized  by  rapid  development  of  and  changes  in  customer
requirements,  frequent  introductions  of  new  and  enhanced  services,  and  continuing  and  rapid  technological  advancement.  We  cannot  predict  the  effect  of
technological  changes  on  our  business,  and  the  market  for  cloud-based  business  communications  may  develop  more  slowly  than  we anticipate,  or  develop  in  a
manner different than we expect, and our solutions could fail to achieve market acceptance. Our continued growth depends on continued use of voice and video
communications  by  businesses,  as  compared  to  email  and  other  data-based  methods,  and  future  demand  for  and  adoption  of  Internet  voice  and  video
communications systems and services. In addition, to compete successfully in this emerging market, we must anticipate and adapt to technological changes and
evolving  industry  standards,  and  continue  to  design,  develop,  manufacture,  and  sell  new  and  enhanced  services  that  provide  increasingly  higher  levels  of
performance  and  reliability  at  lower  cost.  Currently,  we  derive  a  majority  of  our  revenues  from  subscriptions  to  RingCentral  Office,  and  we  expect  this  will
continue for the foreseeable future. However, our future success will also depend on our ability to introduce and sell new services, features, and functionality that
enhance or are beyond the subscriptions we currently offer, as well as to improve usability and support and increase customer satisfaction. Our failure to develop
solutions  that  satisfy  customer  preferences  in  a  timely  and  cost-effective  manner  may  harm  our  ability  to  renew  our  subscriptions  with  existing  customers  and
create or increase demand for our subscriptions and may materially and adversely impact our results of operations.

The introduction of new services by competitors or the development of entirely new technologies to replace existing offerings could make our solutions
obsolete or adversely affect our business and results of operations. Announcements of future releases and new services and technologies by our competitors or us
could  cause  customers  to  defer  purchases  of  our  existing  subscriptions,  which  also  could  have  a  material  adverse  effect  on  our  business,  financial  condition  or
results of operations. We may experience difficulties with software development, operations, design, or marketing that could delay or prevent our development,
introduction, or implementation of new or enhanced services and applications. We have in the past experienced delays in the planned release dates of new features
and upgrades and have discovered defects in new services and applications after their introduction. We cannot assure you that new features or upgrades will be
released according to schedule, or that, when released, they will not contain defects. Either of these situations could result in adverse publicity, loss of revenues,
delay  in  market  acceptance,  or  claims  by  customers  brought  against  us,  all  of  which  could  harm  our  reputation,  business,  results  of  operations,  and  financial
condition. Moreover, the development of new or enhanced services or applications may require substantial investment, and we must continue to invest a significant
amount  of  resources  in  our  research  and  development  efforts  to  develop  these  services  and  applications  to  remain  competitive.  We  do  not  know  whether  these
investments will be successful. If customers do not widely adopt any new or enhanced services and applications, we may not be able to realize a return on our
investment.  If  we  are  unable  to  develop,  license,  or  acquire  new  or  enhanced  services  and  applications  on  a  timely  and  cost-effective  basis,  or  if  such  new  or
enhanced services and applications do not achieve market acceptance, our business, financial condition, and results of operations may be materially and adversely
affected.

If we fail to continue to develop our brand or our reputation is harmed, our business may suffer.

We  believe  that  continuing  to  strengthen  our  current  brand  will  be  critical  to  achieving  widespread  acceptance  of  our  subscriptions  and  will  require
continued  focus  on  active  marketing  efforts.  The  demand  for  and  cost  of  online  and  traditional  advertising  have  been  increasing  and  may  continue  to  increase.
Accordingly, we may need to increase our investment in, and devote greater resources to, advertising, marketing, and other efforts to create and maintain brand
loyalty  among  users.  Brand  promotion  activities  may  not  yield  increased  revenues,  and  even  if  they  do,  any  increased  revenues  may  not  offset  the  expenses
incurred in building our brand. In addition, if we do not handle customer complaints effectively, our brand and reputation may suffer, we may lose our customers’
confidence, and they may choose to terminate, reduce or not to renew their subscriptions. Many of our customers also participate in social media and online blogs
about  Internet-based  software  solutions,  including  our  subscriptions,  and  our  success  depends  in  part  on  our  ability  to  minimize  negative  and  generate  positive
customer feedback through such online channels where existing and potential customers seek and share information. If we fail to sufficiently invest in, promote and
maintain our brand, our business could be materially and adversely affected.

If we experience excessive fraudulent activity or cannot meet evolving credit card association merchant standards, we could incur substantial costs and lose the
right to accept credit cards for payment, which could cause our customer base to decline significantly.

Most of our customers authorize us to bill their credit card accounts directly for service fees that we charge. If customers pay for our subscriptions with
stolen credit cards, we could incur substantial third-party vendor costs for which we may not be reimbursed. Further, our customers provide us with credit card
billing information online or over the phone, and we do not review the physical credit cards used in these transactions, which increases our risk of exposure to
fraudulent activity. We also incur charges, which are referred to in the industry as chargebacks, from the credit card companies from claims that a customer did not
authorize the specific credit card transaction to purchase our subscription. If the number of chargebacks becomes excessive, we could be assessed substantial fines
or be charged higher transaction fees, and we could lose the right to accept credit cards for payment. In addition, credit card issuers may change merchant and/or
service provider standards, including data protection standards, required to utilize their services from time to time. We have established and implemented measures
intended to comply with the Payment Card Industry Data Security Standard (“PCI DSS”) in the U.S., Canada, and the U.K. If we fail to maintain compliance with
such standards or fail to meet new standards, the credit card associations could fine us or terminate their agreements with us, and we would be unable to accept
credit  cards  as  payment  for  our  subscriptions.  If  we fail  to  maintain  compliance  with  current  service  provider  standards,  such  as  PCI DSS, or fail  to  meet  new
standards,  customers  may  choose  not  to  use  our  services  for  certain  types  of  communication  they  have  with  their  customers.  If  such  a  failure  to  comply  with
relevant  standards  occurs,  we  may  also  face  legal  liability  if  we  are  found  to  not  comply  with  applicable  laws  that  incorporate,  by  reference  or  by  adoption  of
substantially similar provisions, merchant or service provider standards, including PCI DSS. Our subscriptions may also be subject to fraudulent usage, including
but not limited to revenue share fraud, domestic traffic pumping, subscription fraud, premium text message scams, and other fraudulent schemes. This usage can
result in, among other things, substantial bills from our vendors, for which we would be responsible, for terminating fraudulent call traffic. In addition, third parties
may have attempted in the past, and may attempt in the future, to induce employees, sub-contractors, or consultants into disclosing customer credentials and other
account  information,  which  can  result  in  unauthorized  access  to  customer  accounts  and  customer  data,  unauthorized  use  of  customers’  services,  charges  to
customers for fraudulent usage and costs that we must pay to carriers. Although we implement multiple fraud prevention and detection controls, we cannot assure
you that these controls will be adequate to protect against fraud. Substantial losses due to fraud or our inability to accept credit card payments could cause our paid
customer  base  to  significantly  decrease,  which  would  have  a  material  adverse  effect  on  our  results  of  operations,  financial  condition,  and  ability  to  grow  our
business.

We are in the process of expanding our international operations, which exposes us to significant risks.

We have significant operations in the U.S., Canada, the U.K., Russia, China, Ukraine, the Philippines and France. We also sell our solutions to customers
in other countries in the EU and in Australia, and we expect to grow our international presence in the future. The future success of our business will depend, in part,
on our ability to expand our operations and customer base worldwide. Operating in international markets requires significant resources and management attention
and will subject us to regulatory, economic, and political risks that are different from those in the U.S. Due to our limited experience with international operations
and developing and managing sales and distribution channels in international markets, our international expansion efforts may not be successful. In addition, we
will face risks in doing business internationally that could materially and adversely affect our business, including:

•

•
•
•
•
•
•
•
•

•
•
•

our  ability  to  comply  with  differing  and  evolving  technical  and  environmental  standards,  telecommunications  regulations,  and  certification
requirements outside the U.S.;
difficulties and costs associated with staffing and managing foreign operations;
our ability to effectively price our subscriptions in competitive international markets;
potentially greater difficulty collecting accounts receivable and longer payment cycles;
the need to adapt and localize our subscriptions for specific countries;
the need to offer customer care in various native languages;
reliance on third parties over which we have limited control, including those that market and resell our subscriptions;
availability of reliable broadband connectivity and wide area networks in targeted areas for expansion;
lower  levels  of  adoption  of  credit  or  debit  card  usage  for  Internet  related  purchases  by  foreign  customers  and  compliance  with  various  foreign
regulations related to credit or debit card processing and data protection requirements;
difficulties in understanding and complying with local laws, regulations, and customs in foreign jurisdictions;
restrictions on travel to or from countries in which we operate or inability to access certain areas;
export controls and economic sanctions;

changes in diplomatic and trade relationships, including tariffs and other non-tariff barriers, such as quotas and local content rules;
U.S. government trade restrictions, including those which may impose restrictions, including prohibitions, on the exportation, re-exportation, sale,
shipment or other transfer of programming, technology, components, and/or services to foreign persons;
our  ability  to  comply  with  different  and  evolving  laws,  rules,  and  regulations,  including  the  European  General  Data  Protection  Regulation  (the
“GDPR”) and other data privacy and data protection laws, rules and regulations;
compliance with various anti-bribery and anti-corruption laws such as the Foreign Corrupt Practices Act and U.K. Bribery Act of 2010;
more limited protection for intellectual property rights in some countries;
adverse tax consequences;
fluctuations in currency exchange rates;
exchange control regulations, which might restrict or prohibit our conversion of other currencies into U.S. dollars;
restrictions on the transfer of funds;
new and different sources of competition;
natural disasters or global health crises, including the ongoing COVID-19 pandemic;
political and economic instability created by the U.K.'s departure from the EU (“Brexit”); and
deterioration  of  political  relations  between  the  U.S.  and  other  countries  in  which  we  operate,  particularly  Russia,  Ukraine,  China,  and  the
Philippines; or
political or social unrest, economic instability, conflict or war in such countries, or sanctions implemented by the U.S. against these countries, all of
which could have a material adverse effect on our operations.

Our failure to manage any of these risks successfully could harm our future international operations and our overall business.

We  may  expand  through  acquisitions  of,  investments  in,  or  strategic  partnerships  or  other  strategic  transactions  with  other  companies,  each  of  which  may
divert  our  management’s  attention,  result  in  additional  dilution  to  our  stockholders,  increase  expenses,  disrupt  our  operations,  and  harm  our  results  of
operations.

Our business strategy may, from time to time, include acquiring or investing in complementary services, technologies or businesses, strategic investments
and partnerships, or other strategic transactions, such as our acquisitions of Dimelo SA and Connect First, and our investment in and strategic partnerships with
Avaya, Atos, ALE and Vodafone. We cannot assure you that we will successfully identify suitable acquisition candidates or transaction counterparties, securely or
effectively integrate or manage disparate technologies, lines of business, personnel and corporate cultures, realize our business strategy or the expected return on
our  investment,  or  manage  a  geographically  dispersed  company.  Any  such  acquisition,  investment,  strategic  partnership,  or  other  strategic  transaction  could
materially and adversely affect our results of operations. The process of negotiating, effecting, and realizing the benefits from acquisitions, investments, strategic
partnerships, and strategic transactions is complex, expensive and time-consuming, and may cause an interruption of, or loss of momentum in, development and
sales activities and operations of both companies, and we may incur substantial cost and expense, as well as divert the attention of management. We may issue
equity securities which could dilute current stockholders’ ownership, incur debt, assume contingent or other liabilities and expend cash in acquisitions, investments,
strategic partnerships, and other strategic transactions which could negatively impact our financial position, stockholder equity, and stock price.

Acquisitions, investments, strategic partnerships, and other strategic transactions involve significant risks and uncertainties, including:

•

•

•

•

•

•

the potential failure to achieve the expected benefits of the acquisition, investment, strategic partnership, or other strategic transaction;

unanticipated costs and liabilities;

difficulties  in  integrating  new  solutions  and  subscriptions,  software,  businesses,  operations,  and  technology  infrastructure  in  an  efficient  and
effective manner;

difficulties in maintaining customer relations;

the potential loss of key employees of any acquired businesses;

the diversion of the attention of our senior management from the operation of our daily business;

28

Table of Contents

•

•

•

•

•

•

the potential adverse effect on our cash position to the extent that we use cash for the transaction consideration;

the  potential  significant  increase  of  our  interest  expense,  leverage,  and  debt  service  requirements  if  we  incur  additional  debt  to  pay  for  an
acquisition, investment, strategic partnership, or other strategic transaction;

the potential issuance of securities that would dilute our stockholders’ percentage ownership;

the potential to incur large and immediate write-offs and restructuring and other related expenses;

the potential liability or expenses associated with new types of data stored, existing security obligations or liabilities, unknown weaknesses in our
solutions, insufficient security measures in place, and compromise of our networks via access to our systems from assets not previously under our
control; and

the inability to maintain uniform standards, controls, policies, and procedures.

Any acquisition, investment, strategic partnership, or other strategic transaction could expose us to unknown liabilities. Moreover, we cannot assure you
that  we  will  realize  the  anticipated  benefits  of  any  acquisition,  investment,  strategic  partnership,  or  other  strategic  transaction.  In  addition,  our  inability  to
successfully operate and integrate newly acquired businesses or newly formed strategic partnerships appropriately, effectively, and in a timely manner could impair
our ability to take advantage of future growth opportunities and other advances in technology, as well as on our revenues, gross margins, and expenses.

For  example,  in  connection  with  our  strategic  partnership  with  Avaya,  we  purchased  $125.0  million  of  Avaya  Series  A  Preferred  Stock  and  made  an
advance  of  $375.0  million,  predominantly  for  future  fees,  as  well  as  for  certain  licensing  rights  (paid  primarily  in  our  Class  A  Common  Stock).  These  are
significant investments on which we may not realize the anticipated benefits for various reasons, including a lack of success in the marketing and sale of ACO,
potential  or actual  financial  distress,  insolvency,  or bankruptcy  of Avaya or any of its subsidiaries,  or other  facts  or circumstances  that  may limit  our ability  to
recover, or realize benefits from, these investments.

We  may  be  subject  to  liabilities  on  past  sales  for  taxes,  surcharges,  and  fees  and  our  operating  results  may  be  harmed  if  we  are  required  to  collect  such
amounts in jurisdictions where we have not historically done so.

We believe we collect state and local sales tax and use, excise, utility user, and ad valorem taxes, fees, or surcharges in all relevant jurisdictions in which
we generate sales, based on our understanding of the applicable laws in those jurisdictions. Such tax, fees and surcharge laws and rates vary greatly by jurisdiction,
and the application of such taxes to e-commerce businesses, such as ours, is a complex and evolving area. There is uncertainty as to what constitutes sufficient “in
state presence” for a state to levy taxes, fees, and surcharges for sales made over the Internet, and after the U.S. Supreme Court’s ruling in South Dakota v. Wayfair,
U.S. states may require an online retailer with no in-state property or personnel to collect and remit sales tax on sales to the state’s residents, which may permit
wider enforcement of sales tax collection requirements. Therefore, the application of existing or future laws relating to indirect taxes to our business, or the audit of
our business and operations with respect to such taxes or challenges of our positions by taxing authorities, all could result in increased tax liabilities for us or our
customers that could materially and adversely affect our results of operations and our relationships with our customers.

We may be unable to use some or all of our net operating loss carryforwards, which could materially and adversely affect our reported financial condition and
results of operations.

As of December 31, 2020, we have federal net operating loss carryforwards (“NOLs”) of $1.4 billion, of which $272.9 million expire between 2023 and
2037 and the remainder do not expire. Additionally, we have state net operating loss carryforwards of $1.1 billion which will begin to expire in 2021. We also have
federal research tax credit carryforwards that will begin to expire in 2028. Realization of these net operating loss and research tax credit carryforwards depends on
future  income,  and  there  is  a  risk  that  our  existing  carryforwards  could  expire  unused  and  be  unavailable  to  offset  future  income  tax  liabilities,  which  could
materially and adversely affect our results of operations.

In addition, under Sections 382 and 383 of the Internal Revenue Code of 1986, as amended, our ability to utilize NOLs or other tax attributes, such as
research  tax  credits,  in  any  taxable  year  may  be  limited  if  we  experience  an  “ownership  change.”  An  “ownership  change”  generally  occurs  if  one  or  more
stockholders or groups of stockholders, who each own at least 5% of our stock, increase their collective 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.

29

Table of Contents

No material deferred tax assets have been recognized on our Consolidated Balance Sheets related to these NOLs, as they are fully offset by a valuation
allowance. If we have previously had, or have in the future, one or more Section 382 “ownership changes,” including in connection with our initial public offering
or  another  offering,  or  if  we  do  not  generate  sufficient  taxable  income,  we  may  not  be  able  to  utilize  a  material  portion  of  our  NOLs,  even  if  we  achieve
profitability. If we are limited in our ability to use our NOLs in future years in which we have taxable income, we will pay more taxes than if we were able to fully
utilize our NOLs. This could materially and adversely affect our results of operations.

If we are unable to effectively process local number and toll-free number portability provisioning in a timely manner, our growth may be negatively affected.

We support local number and toll-free number portability, which allows our customers to transfer to us and thereby retain their existing phone numbers
when subscribing to our services. Transferring numbers is a manual process that can take up to 15 business days or longer to complete. A new customer of our
subscriptions must maintain both our subscription and the customer’s existing phone service during the number transferring process. Any delay that we experience
in transferring these numbers typically results from the fact that we depend on third-party carriers to transfer these numbers, a process that we do not control, and
these third-party carriers may refuse or substantially delay the transfer of these numbers to us. Local number portability is considered an important feature by many
potential customers, and if we fail to reduce any related delays, we may experience increased difficulty in acquiring new customers. Moreover, the FCC requires
Internet voice communications providers to comply with specified number porting timeframes when customers leave our subscription for the services of another
provider.  Several  international  jurisdictions  have  imposed  similar  number  portability  requirements  on  subscription  providers  like  us.  If  we  or  our  third-party
carriers are unable to process number portability requests within the requisite timeframes, we could be subject to fines and penalties. Additionally, in the U.S., both
customers  and  carriers  may  seek  relief  from  the  relevant  state  public  utility  commission,  the  FCC,  or  in  state  or  federal  court  for  violation  of  local  number
portability requirements.

Our business could suffer if we cannot obtain or retain direct inward dialing numbers or are prohibited from obtaining local or toll-free numbers or if we are
limited to distributing local or toll-free numbers to only certain customers.

Our future success depends on our ability to procure large quantities of local and toll-free direct inward dialing numbers (“DIDs”) in the U.S. and foreign
countries in desirable locations at a reasonable cost and without restrictions. Our ability to procure and distribute DIDs depends on factors outside of our control,
such as applicable regulations, the practices of the communications carriers that provide DIDs, the cost of these DIDs, and the level of demand for new DIDs. Due
to their limited availability, there are certain popular area code prefixes that we generally cannot obtain. Our inability to acquire DIDs for our operations would
make our subscriptions less attractive to potential customers in the affected local geographic areas. In addition, future growth in our customer base, together with
growth in the customer bases of other providers of cloud-based business communications, has increased, which increases our dependence on needing sufficiently
large quantities of DIDs.

We may not be able to manage our inventory levels effectively, which may lead to inventory obsolescence that would force us to incur inventory write-downs.

Our vendor-supplied phones have lead times of up to several months for delivery to our fulfillment agents and are built to forecasts that are necessarily
imprecise. It is likely that, from time to time, we will have either excess or insufficient product inventory. In addition, because we rely on third-party vendors for
the supply of our vendor-supplied phones, our inventory levels are subject to the conditions regarding the timing of purchase orders and delivery dates that are not
within  our  control.  Excess  inventory  levels  would  subject  us  to  the  risk  of  inventory  obsolescence,  while  insufficient  levels  of  inventory  may  negatively  affect
relations with customers. For instance, our customers rely upon our ability to meet committed delivery dates, and any disruption in the supply of our subscriptions
could result in loss of customers or harm to our ability to attract new customers. Any reduction or interruption in the ability of our vendors to supply our customers
with vendor-supplied phones, including as a result of the ongoing COVID-19 pandemic, could cause us to lose revenue, damage our customer relationships and
harm our reputation in the marketplace. Any of these factors could have a material adverse effect on our business, financial condition or results of operations.

30

Table of Contents

We currently depend on three phone device suppliers and two fulfillment agents to configure and deliver the phones that we sell and any delay or interruption
in manufacturing, configuring and delivering by these third parties would result in delayed or reduced shipments to our customers and may harm our business.

We rely on three suppliers to provide phones that we offer for sale to our customers that use our subscriptions, and we rely on two fulfillment agents to
configure  and  deliver  the  phones  that  we  sell  to  our  customers.  Accordingly,  we  could  be  adversely  affected  if  such  third  parties  fail  to  maintain  competitive
phones  or  configuration  services  or  fail  to  continue  to  make  them  available  on  attractive  terms,  or  at  all.  These  suppliers  have  been  and  will  continue  to  be
adversely impacted by the COVID-19 pandemic, which could affect their ability to perform satisfactorily or at all.

If our fulfillment agents are unable to deliver phones of acceptable quality, or if there is a reduction or interruption in their ability to supply the phones in
a timely manner, our ability to bring services to market, the reliability of our subscriptions and our relationships with customers or our overall reputation in the
marketplace  could  suffer,  which  could  cause  us  to  lose  revenue.  We  expect  that  it  could  take  several  months  to  effectively  transition  to  new  third-party
manufacturers or fulfillment agents.

If our vendor-supplied phones are not able to interoperate effectively with our own back-end servers and systems, our customers may not be able to use our
subscriptions, which could harm our business, financial condition and results of operations.

Phones  must  interoperate  with  our  back-end  servers  and  systems,  which  contain  complex  specifications  and  utilize  multiple  protocol  standards  and
software  applications.  Currently,  the phones used by our customers  are manufactured  by only three  third-party  providers.  If any of these  providers changes  the
operation of their phones, we will be required to undertake development and testing efforts to ensure that the new phones interoperate with our system. In addition,
we must be successful in integrating our solutions with strategic partners' devices in order to market and sell these solutions. These efforts may require significant
capital and employee resources, and we may not accomplish these development efforts quickly or cost-effectively, if at all. If our vendor-supplied phones do not
interoperate effectively with our system, our customers’ ability to use our subscriptions could be delayed or orders for our subscriptions could be canceled, which
would harm our business, financial condition, and results of operations.

We  may  require  additional  capital  to  pursue  our  business  objectives  and  to  respond  to  business  opportunities,  challenges  or  unforeseen  circumstances.  If
capital is not available to us, our business, results of operations, and financial condition may be adversely affected.

We  intend  to  continue  to  make  expenditures  and  investments  to  support  the  growth  of  our  business  and  may  require  additional  capital  to  pursue  our
business objectives and respond to business opportunities, challenges, or unforeseen circumstances, including the need to develop new solutions or enhance our
existing solutions, enhance our operating infrastructure, and acquire complementary businesses and technologies. Accordingly, we may need to engage in equity or
debt financings to secure additional funds. However, additional funds may not be available when we need them on terms that are acceptable to us, or at all. Any
debt financing that we secure in the future could involve restrictive covenants, which may make it more difficult for us to obtain additional capital and to pursue
business  opportunities.  In  addition,  the  restrictive  covenants  in  credit  facilities  we  may  secure  in  the  future  may  restrict  us  from  being  able  to  conduct  our
operations in a manner required for our business and may restrict our growth, which could have an adverse effect on our business, financial condition, or results of
operations.

We cannot assure you that we will be able to comply with any such restrictive covenants. In the event that we are unable to comply with these covenants
in the future, we would seek an amendment or waiver of the covenants. We cannot assure you that any such waiver or amendment would be granted. In such event,
we may be required to repay any or all of our existing borrowings, and we cannot assure you that we will be able to borrow under our existing credit agreements, or
obtain alternative funding arrangements on commercially reasonable terms, or at all.

In  addition,  volatility  in  the  credit  markets,  including  any  due  to  the  COVID-19  pandemic,  may  have  an  adverse  effect  on  our  ability  to  obtain  debt
financing. The conversion of our 0% convertible senior notes due 2023 (the “2023 Notes”), our 0% convertible senior notes due 2025 (the “2025 Notes”) and our
0% convertible senior notes due 2026 (the “2026 Notes” and, together with the 2023 Notes and the 2025 Notes, the “Notes”) and any future issuances of other
equity  or  any  future  issuances  of  equity  or  convertible  debt  securities  could  result  in  significant  dilution  to  our  existing  stockholders,  and  any  new  equity  or
convertible debt securities we issue could have rights, preferences, and privileges superior to those of holders of our Class A Common Stock. If we are unable to
obtain adequate financing or financing on terms satisfactory to us, when we require it, our

31

Table of Contents

ability  to  continue  to  pursue  our  business  objectives  and  to  respond  to  business  opportunities,  challenges,  or  unforeseen  circumstances  could  be  significantly
limited, and our business, results of operations, financial condition and prospects could be materially and adversely affected.

Risks Related to Regulatory Matters

Our subscriptions are subject to regulation, and future legislative or regulatory actions could adversely affect our business and expose us to liability in the U.S.
and internationally.

Federal Regulation

Our business is regulated by the FCC. As a communications services provider, we are subject to existing or potential FCC regulations relating to privacy,
disability access, porting of numbers, maintaining records for disconnected numbers, cooperation with law enforcement, Federal Universal Service Fund (“USF”)
contributions,  Enhanced  911  (“E-911”),  outage  reporting,  call  authentication,  call  spoofing,  call  blocking  and  other  requirements  and  regulations.  FCC
classification of our Internet voice communications services as telecommunications services could result in additional federal and state regulatory obligations. If we
do not comply with FCC rules and regulations, we could be subject to FCC enforcement actions, fines, loss of licenses, and possibly restrictions on our ability to
operate  or  offer  certain  of  our  subscriptions.  Any  enforcement  action  by  the  FCC,  which  may  be  a  public  process,  would  hurt  our  reputation  in  the  industry,
possibly impair our ability to sell our subscriptions to customers and could have a materially adverse impact on our revenues.

Through  RCLEC,  we  also  provide  competitive  local  exchange  carrier  (“CLEC”)  services  which  are  regulated  by  the  FCC  as  traditional
telecommunications  services.  Our  CLEC  services  depend  on  certain  provisions  of  the  Telecommunications  Act  of  1996  that  require  incumbent  local  exchange
carriers (“ILECs”) to provide us facilities and services that are necessary to provide our services. Over the past several years, the FCC has reduced or eliminated a
number of regulations governing ILECs’ wholesale offerings. If ILECs were no longer required by law to provide such services to us, or ceased to provide these
services at reasonable rates, terms and conditions, our business could be adversely affected and our cost of providing CLEC services could increase. This could
have a materially adverse impact on our results of operations and cash flows.

In  addition,  the  federal  Telephone  Consumer  Protection  Act  (“TCPA”)  and  FCC rules  implementing  the  TCPA, prohibit  sending  unsolicited  facsimile
advertisements or making illegal robocalls, subject to certain exceptions. The FCC may take enforcement action against persons or entities that send “junk faxes,”
or make illegal robocalls and individuals also may have a private cause of action. Although the FCC’s rules prohibiting unsolicited fax advertisements or making
illegal robocalls apply to those who “send” the advertisements or make the calls, fax transmitters or other service providers that have a high degree of involvement
in,  or  actual  notice  of,  unlawful  sending  of  junk  faxes  or  making  of  illegal  robocalls  and  have  failed  to  take  steps  to  prevent  such  transmissions  may  also  face
liability under the FCC’s rules, or in the case of illegal robocalls, Federal Trade Commission rules. We take significant steps designed to prevent our systems from
being used to make illegal robocalls or send unsolicited faxes on a large scale, and we do not believe that we have a high degree of involvement in, or notice of, the
use of  our systems  to  broadcast  junk faxes  or make  illegal  robocalls.  However, because  fax transmitters  and  related  service  providers  do not enjoy  an absolute
exemption from liability under the TCPA and related FCC rules, we could face FCC or FTC inquiry and enforcement or civil litigation, or private causes of action,
if someone uses our system for such purposes. If any of these were to occur, we could be required to incur significant costs and management’s attention could be
diverted. Further, if we were to be held liable for the use of our service to send unsolicited faxes or make illegal robocalls or to settle any action or proceeding, any
judgment, settlement, or penalties could cause a material adverse effect on our operations.

State Regulation

States currently do not regulate our Internet voice communications subscriptions, which are considered to be nomadic because they can be used from any
broadband connection. However, a number of states require us to register as a Voice over Internet Protocol (“VoIP”) provider, contribute to state USF, contribute
to E-911, and pay other  surcharges  and annual  fees  that fund various  utility  commission  programs,  while others are  actively  considering  extending their  public
policy  programs  to  include  the  subscriptions  we  provide.  We  pass  USF,  E-911  fees,  and  other  surcharges  through  to  our  customers,  which  may  result  in  our
subscriptions  becoming  more  expensive  or  require  that  we  absorb  these  costs.  State  public  utility  commissions  may  attempt  to  apply  state  telecommunications
regulations to Internet voice communications subscriptions like ours.

RCLEC services are subject to regulation by the public utility regulatory agency in those states where we provide local telecommunications services. This
regulation includes the requirement to obtain a certificate of public convenience and necessity or other similar licenses prior to offering our CLEC services. We
may also be required to file tariffs that describe our CLEC services and provide rates for those services. We are also required to comply with regulations that vary
by state

32

Table of Contents

concerning  service  quality,  disconnection  and  billing  requirements.  State  commissions  also  have  authority  to  review  and  approve  interconnection  agreements
between incumbent phone carriers and CLECs such as our subsidiary.

Both we and RCLEC are also subject to state consumer protection laws, as well as U.S. state or municipal sales, use, excise, gross receipts, utility user and

ad valorem taxes, fees, or surcharges.

International Regulation

As we expand internationally, we may be subject to telecommunications, consumer protection, data protection, emergency call services, and other laws,
regulations, taxes, and fees in the foreign countries where we offer our subscriptions. Any foreign regulations could impose substantial compliance costs on us,
restrict  our  ability  to  compete,  and  impact  our  ability  to  expand  our  service  offerings  in  certain  markets.  Moreover,  the  regulatory  environment  is  constantly
evolving  and  changes  to  the  applicable  regulations  could  impose  additional  compliance  costs  and  require  modifications  to  our  technology  and  operations.
Internationally,  we  currently  offer  our  subscriptions  in  Canada,  the  U.K.,  Australia,  and  several  European  countries.  We  also  offer  our  Global  Office  solution,
enabling  our  multinational  customers  in  the  U.S.,  U.K.,  Canada,  and  other  locations  where  we  sell  our  solutions,  to  establish  local  phone  solutions  in  various
countries internationally. We may be subject to telecommunications, consumer protection, data protection, emergency call services, call authentication, and other
laws and regulations in additional countries as we continue to expand our Global Office solution internationally.

In addition, our international operations are potentially subject to country-specific governmental regulation and related actions that may increase our costs
or  impact  our  solution  and  service  offerings  or  prevent  us  from  offering  or  providing  our  solutions  and  subscriptions  in  certain  countries.  Certain  of  our
subscriptions may be used by customers located in countries where VoIP and other forms of IP communications may be illegal or require special licensing or in
countries on a U.S. embargo list. Even where our solutions are reportedly illegal or become illegal or where users are located in an embargoed country, users in
those countries may be able to continue to use our solutions and subscriptions in those countries notwithstanding the illegality or embargo. We may be subject to
penalties or governmental action if customers continue to use our solutions and subscriptions in countries where it is illegal to do so, and any such penalties or
governmental action may be costly and may harm our business and damage our brand and reputation. We may be required to incur additional expenses to meet
applicable  international  regulatory  requirements  or  be  required  to  discontinue  those  subscriptions  if  required  by  law  or  if  we  cannot  or  will  not  meet  those
requirements.

The  increasing  growth  and  popularity  of  Internet  voice  communications,  video  conferencing  and  messaging  heighten  the  risk  that  governments  will
regulate or impose new or increased fees or taxes on these services. To the extent that the use of our subscriptions continues to grow, and our user base continues to
expand, regulators may be more likely to seek to regulate or impose new or additional taxes, surcharges or fees on our subscriptions.

We  process,  store,  and  use  personal  information  and  other  data,  which  subjects  us  and  our  customers  to  a  variety  of  evolving  international
statutes, governmental regulation, industry standards and self-regulatory schemes, contractual obligations, and other legal obligations related to privacy and
data protection, which may increase our costs, decrease adoption and use of our solutions and subscriptions, and expose us to liability.

In the course of providing our services, we collect, store, and process many types of data, including personal data. Moreover, our customers can use our
subscriptions to store contact and other personal or identifying information, and to process, transmit, receive, store, and retrieve a variety of communications and
messages, including information about their own customers and other contacts. Customers are able, and may be authorized under certain circumstances, to use our
subscriptions to transmit, receive, and/or store personal information.

There are a number of federal, state, local, and foreign laws and regulations, as well as contractual obligations and industry standards, that provide for
certain  obligations  and  restrictions  with  respect  to  data  privacy  and  security,  and  the  collection,  storage,  retention,  protection,  use,  processing,  transmission,
sharing, disclosure, and protection of personal information and other customer data. We expect that with the implementation of our Global Office solution, we may
become subject to additional data privacy regulations in other countries throughout the world. The scope of these obligations and restrictions is changing, subject to
differing  interpretations,  and  may  be  inconsistent  among  countries  or  conflict  with  other  rules,  and  their  status  remains  uncertain.  Failure  to  comply  with
obligations  and  restrictions  related  to  data  privacy  and  security  in  any  jurisdiction  in  which  we  operate  could  subject  us  to  lawsuits,  fines,  criminal  penalties,
statutory damages, consent decrees, injunctions, adverse publicity, and other losses that could harm our business.

For example, the GDPR, which came into force in May 2018, strengthened the existing data protection regulations in the EU and its provisions include

increasing the maximum level of fines that EU regulators may impose for the most serious of

33

Table of Contents

breaches to the greater of €20 million or 4% of worldwide annual turnover. Such fines would be in addition to (i) the rights of individuals to sue for damages in
respect of any data privacy breach which causes them to suffer harm and (ii) the right of individual member states to impose additional sanctions over and above
the administrative fines specified in the GDPR. Other examples include, but are not limited to, Canadian anti-spam legislation and Australia’s Spam Act 2003, as
amended.

Until recently, we used the EU-U.S. Privacy Shield framework as well as the Swiss-U.S. Privacy Shield framework and EU Standard Contractual Clauses
(“Model Clauses”) to protect data exports between the European Economic Area (the “EEA”) and U.S. On July 16, 2020, the Court of Justice of the European
Union, invalidated  the EU-U.S. Privacy  Shield as a mechanism  to transfer  EU personal  data to the U.S. and imposed  additional  requirements  for data transfers
under  Model  Clauses.  On  September  8,  2020  the  Federal  Data  Protection  and  Information  Commissioner  of  Switzerland  issued  an  opinion  concluding  that  the
Swiss-U.S. Privacy Shield did not provide an adequate level of protection for data transfers from Switzerland to the U.S. pursuant to Swiss data protection law. We
are putting in place alternative data transfer mechanisms such as additional Model Clauses where we previously relied on the EU-U.S. Privacy Shield and Swiss-
U.S. Privacy Shield frameworks. Data protection authorities may require measures be put in place in addition to Model Clauses for transfers to countries outside of
the EEA and Switzerland. We may, in addition to other impacts, experience additional costs associated with increased compliance burdens following this decision,
and we and our customers face the potential for regulators in the EEA or Switzerland to apply different standards to the transfer of personal data from the EEA or
Switzerland to the U.S. and other non-EEA countries, and to block, or require ad hoc verification of measures taken with respect to, certain data flows from the
EEA  and  Switzerland  to  the  U.S  and  other  non-EEA  countries.  We  also  may  be  required  to  engage  in  new  contract  negotiations  with  third  parties  that  aid  in
processing data on our behalf.

The future of cross-border data flows from the EEA to the U.K. following the U.K.’s exit from the EU on January 31, 2020 is uncertain. Although the
transition period ended on December 31, 2020, the UK-EU Trade Cooperation Agreement delays any restrictions on cross-border data flows from the EEA to the
UK for up to six months (the "Bridge"). If the EU does not provide the UK with an adequacy determination during the Bridge, it may become necessary for us to
implement additional data export solutions like the Model Clauses to enable the continued flow of personal data to our U.K. operations from our EEA customers
and affiliates. These solutions may take time and be challenging to put in place and, if not implemented promptly before or immediately following the Bridge, our
business may be disrupted, and we may be exposed to potential regulatory fines and civil claims.

These  developments  and  future  regulatory  guidance  may  result  in  a  determination  that  the  industry-standard  measures  we,  and  other  companies,  have
taken are insufficient. Additionally, it is possible that the EU-U.S. Privacy Shield, the Swiss-U.S. Privacy Shield and/or the Model Clauses may be updated by the
European  Commission,  the  Swiss  Administration,  and  the  U.S.  Department  of  Commerce.  Should  any  of  these  prove  to  be  the  case,  we  will  need  to  take  any
necessary and additional measures to ensure compliance with EU, Swiss and U.K. law with respect to our transfers of personal data from the EEA, Switzerland and
the U.K. to the U.S. and other non-EEA countries. If we are unable to take such measures, then we may be at risk of experiencing reluctance or refusal of European
or multi-national customers to use our solutions and incurring regulatory penalties, which may have an adverse effect on our business.

In  the  U.S.,  there  are  numerous  federal  and  state  laws  governing  the  privacy  and  security  of  personal  information.  In  particular,  the  Health  Insurance
Portability and Accountability Act of 1996 (“HIPAA”) establishes privacy and security standards that limit the use and disclosure of individually identifiable health
information and requires the implementation of administrative, physical, and technical safeguards to protect the privacy of protected health information and ensure
the  confidentiality,  integrity,  and  availability  of  electronic  protected  health  information  by  certain  institutions.  We  act  as  a  “Business  Associate”  through  our
relationships with certain customers and are thus directly subject to certain provisions of HIPAA. In addition, if we are unable to protect the privacy and security of
protected health information, we could be found to have breached our contracts with customers with whom we have a Business Associate relationship and may also
face  regulatory  liability.  Additionally,  we  are  subject  to  FCC  regulations  imposing  obligations  related  to  our  use  and  disclosure  of  certain  data  related  our
interconnected VoIP service. If we experience a data security incident, we may be required by state law or FCC or other regulations to notify our customers and/or
law enforcement. We may also be subject to Federal Trade Commission (“FTC”) enforcement actions if the FTC has reason to believe we have engaged in unfair
or deceptive privacy or data security practices.

Noncompliance  with  laws  and  regulations  relating  to  privacy  and  security  of  personal  information,  including  HIPAA,  or  with  contractual  obligations
under  any  Business  Associate  agreement  may  lead  to  significant  fines,  civil  and  criminal  penalties,  or  liabilities.  The  U.S.  Department  of  Health  and  Human
Services (“HHS”) audits the compliance of Business Associates and enforces HIPAA privacy and security standards. HHS enforcement activity has become more
significant  over  the  last  few  years  and  HHS  has  signaled  its  intent  to  continue  this  trend.  Violation  of  the  FCC’s  privacy  rules  can  result  in  large  monetary
forfeitures and injunctive relief. The FTC has broad authority to seek monetary redress for affected consumers and

34

Table of Contents

injunctive relief. In addition to federal regulators, state attorneys general (and, in some states, individual residents) are authorized to bring civil actions seeking
either  injunctions  or  damages  to  the  extent  violations  implicate  the  privacy  of  state  residents.  Class  action  lawsuits  are  common  in  the  event  of  a  data  breach
affecting financial or other forms of sensitive information.

Additionally,  California  has  enacted  the  California  Consumer  Privacy  Act  (“CCPA”),  which  came  into  effect  on  January  1,  2020,  with  implementing
regulations  effective  August  14,  2020.  Pursuant  to  the  CCPA,  we  are  required,  among  other  things,  to  make  certain  enhanced  disclosures  related  to  California
residents  regarding  our  use  or  disclosure  of  their  personal  information,  allow  California  residents  to  opt-out  of  certain  uses  and  disclosures  of  their  personal
information without penalty, provide Californians with other choices related to personal data in our possession, and obtain opt-in consent before engaging in certain
uses of personal information relating to Californians under the age of 16. The California Attorney General may seek substantial monetary penalties and injunctive
relief  in  the  event  of  our  non-compliance  with  the  CCPA.  The  CCPA  also  allows  for  private  lawsuits  from  Californians  in  the  event  of  certain  data  breaches.
Aspects of the CCPA remain uncertain, and we may be required to make modifications to our policies or practices in order to comply. Moreover, a new proposed
privacy  law,  the  California  Privacy  Rights  Act  (“CPRA”)  recently  was  approved  by  California  voters.  The  CPRA significantly  modifies  the  CCPA, potentially
resulting in further uncertainty and requiring us to incur additional costs and expenses in an effort to comply. The CPRA creates obligations relating to consumer
data beginning on January 1, 2022, with implementing regulations expected on or before July 1, 2022, and enforcement beginning July 1, 2023.

As Internet commerce and communication technologies continue to evolve, thereby increasing online service providers’ and network users’ capacity to
collect,  store,  retain,  protect,  use,  process,  and  transmit  large  volumes  of  personal  information,  increasingly  restrictive  regulation  by  federal,  state,  or  foreign
agencies becomes more likely.

While we try to comply with applicable data protection laws, regulations, standards, and codes of conduct, as well as our own posted privacy policies and
contractual commitments to the extent possible, any actual or alleged failure by us to comply with any of the foregoing or to protect our users’ privacy and data,
including  as a result of our systems being  compromised  by hacking  or other  malicious  or surreptitious  activity,  could result  in a loss of user confidence  in our
subscriptions and ultimately in a loss of users, which could materially and adversely affect our business.

Regulation of personal information is evolving, and new laws, such as those in Brazil, could further impact how we handle personal information or could
require us to incur additional compliance costs, either of which could have an adverse impact on our operations. Further, our actual compliance, our customers’
perception  of  our  compliance,  costs  of  compliance  with  such  regulations,  and  obligations  and  customer  concerns  regarding  their  own  compliance  obligations
(whether factual or in error) may limit the use and adoption of our subscriptions and reduce overall demand. Privacy-related concerns, including the inability or
impracticality  of  providing  advance  notice  to  customers  of  privacy  issues  related  to  the  use  of  our  subscriptions,  may  cause  our  customers’  customers  to  resist
providing the personal data necessary to allow our customers to use our subscriptions effectively. Even the perception of privacy-related concerns, whether or not
valid, may inhibit market adoption of our subscriptions in certain industries.

Additionally,  due  to  the  nature  of  our  service,  we  are  unable  to  maintain  complete  control  over  data  security  or  the  implementation  of  measures  that
reduce the risk of a data security incident. For example, our customers may accidentally disclose their passwords or store them on a mobile device that is lost or
stolen,  creating  the  perception  that  our  systems  are  not  secure  against  third-party  access.  Additionally,  our  third-party  contractors  in  the  Philippines,  Russia,
Ukraine, India, and Poland may have access to customer data. If these or other third-party vendors violate applicable laws or our policies, such violations may also
put our customers’ information at risk and could in turn have a material and adverse effect on our business.

Our emergency and E-911 calling services may expose us to significant liability.

The  FCC  requires  Internet  voice  communications  providers,  such  as  our  company,  to  provide  E-911  service  in  all  geographic  areas  covered  by  the
traditional  wire-line  E-911  network.  Under  the  FCC’s  rules,  Internet  voice  communications  providers  must  transmit  the  caller’s  phone  number  and  registered
location information to the appropriate public safety answering point (“PSAP”) for the caller’s registered location. Our CLEC services are also required by the FCC
and state regulators to provide E-911 service to the extent that they provide services to end users. We are also subject to similar requirements internationally.

In  connection  with  the  regulatory  requirements  that  we  provide  access  to  emergency  services  dialing  to  our  interconnected  VoIP  customers,  we  must
obtain from each customer, prior to the initiation of or changes to service, the physical locations at which the service will first be used for each VoIP line. For
subscriptions that can be utilized from more than one

35

Table of Contents

physical location, we must provide customers one or more methods of updating their physical location. Because we are not able to confirm that the service is used
at the physical addresses provided by our customers, and because customers may provide an incorrect location or fail to provide updated location information, it is
possible that emergency services calls may get routed to the wrong PSAP. If emergency services calls are not routed to the correct PSAP, and if the delay results in
serious  injury  or  death,  we  could  be  sued  and  the  damages  substantial.  We  are  evaluating  measures  to  attempt  to  verify  and  update  the  addresses  for  locations
where our subscriptions are used.

In August 2019, the FCC adopted an order that will require providers of non-fixed interconnected VoIP service (service that is capable of being used from
more than one location) to automatically provide with each 911 call, when technically feasible, specific address information that can be used to adequately identify
the location of the caller. The requirement is scheduled to take effect on January 6, 2022. The implementation of this requirement may increase our costs and make
our service more expensive, which could adversely affect our results of operations.

We could be subject to enforcement action by the FCC or international regulators for our customer lines that cannot provide access to emergency services
in  accordance  with  regulatory  requirements.  This  enforcement  action  could  result  in  significant  monetary  penalties  and  restrictions  on  our  ability  to  offer  non-
compliant subscriptions.

In addition, customers may attempt to hold us responsible for any loss, damage, personal injury, or death suffered as a result of delayed, misrouted, or
uncompleted  emergency  service  calls  or  text  messages,  subject  to  any  limitations  on  a  provider’s  liability  provided  by  applicable  laws,  regulations  and  our
customer agreements.

We rely on third parties to provide the majority of our customer service and support representatives and to fulfill various aspects of our E-911 service. If these
third parties do not provide our customers with reliable, high-quality service, our reputation will be harmed, and we may lose customers.

We offer customer support through both our online account management website and our toll-free customer support number in multiple languages. Our
customer support is currently provided via a third-party provider located in the Philippines, as well as our employees in the U.S. Our third-party providers generally
provide  customer  service  and  support  to  our  customers  without  identifying  themselves  as  independent  parties.  The  ability  to  support  our  customers  may  be
disrupted  by  natural  disasters,  inclement  weather  conditions,  civil  unrest,  strikes,  and  other  adverse  events  in  the  Philippines.  Furthermore,  as  we  expand  our
operations internationally, we may need to make significant expenditures and investments in our customer service and support to adequately address the complex
needs of international customers, such as support in additional foreign languages. We also use third parties to deliver onsite professional services to our customers
in deploying our solutions. If these vendors do not deliver timely and high-quality services to our customers, our reputation could be damaged, and we could lose
customers. In addition, third party professional services vendors may not be available when needed, which would adversely impact our ability to deliver on our
customer commitments.

We also contract with third parties to provide emergency services calls in the U.S., Canada, the U.K., and other jurisdictions in which we provide access
to emergency services dialing, including assistance in routing emergency calls and terminating emergency services calls. Our domestic providers operate a national
call center that is available 24 hours a day, seven days a week, to receive certain emergency calls and maintain PSAP databases for the purpose of deploying and
operating E-911 services. We rely on providers for similar functions in other jurisdictions in which we provide access to emergency services dialing. On mobile
devices, we rely on the underlying cellular or wireless carrier to provide emergency services dialing. Interruptions in service from our vendors could cause failures
in our customers’ access to E-911/999/112 services and expose us to liability and damage our reputation.

If  any  of  these  third  parties  do  not  provide  reliable,  high-quality  service,  our  reputation  and  our  business  will  be  harmed.  In  addition,  industry

consolidation among providers of services to us may impact our ability to obtain these services or increase our costs for these services.

Risks Related to Intellectual Property

Accusations of infringement of third-party intellectual property rights could materially and adversely affect our business.

There has been substantial litigation in the areas in which we operate regarding intellectual property rights. For instance, we have recently and in the past
been sued by third parties claiming infringement of their intellectual property rights and we may be sued for infringement from time to time in the future. Also, in
some instances, we have agreed to indemnify our

36

Table of Contents

customers, resellers, and carriers for expenses and liability resulting from claimed intellectual property infringement by our solutions. From time to time, we have
received requests for indemnification in connection with allegations of intellectual property infringement and we may choose, or be required, to assume the defense
and/or  reimburse  our  customers  and/or  resellers  and  carriers  for  their  expenses,  settlement  and/or  liability.  In  the  past,  we  have  settled  infringement  litigation
brought against us; however, we cannot assure you that we will be able to settle any future claims or, if we are able to settle any such claims, that the settlement
will be on terms favorable to us. Our broad range of technology may increase the likelihood that third parties will claim that we, or our customers and/or resellers,
and carriers, infringe their intellectual property rights.

We have in the past received, and may in the future receive, notices of claims of infringement, misappropriation or misuse of other parties’ proprietary
rights.  Furthermore,  regardless  of  their  merits,  accusations  and  lawsuits  like  these,  whether  against  us  or  our  customers,  resellers,  and  carriers,  may  require
significant time and expense to defend, may negatively affect customer relationships, may divert management’s attention away from other aspects of our operations
and, upon resolution, may have a material adverse effect on our business, results of operations, financial condition, and cash flows.

Certain technology necessary for us to provide our subscriptions may, in fact, be patented by other parties either now or in the future. If such technology
were validly patented by another person, we would have to negotiate a license for the use of that technology. We may not be able to negotiate such a license at a
price that is acceptable to us or at all. The existence of such a patent, or our inability to negotiate a license for any such technology on acceptable terms, could force
us to cease using the technology and cease offering subscriptions incorporating the technology, which could materially and adversely affect our business and results
of operations.

If we, or any of our solutions, were found to be infringing on the intellectual property rights of any third party, we could be subject to liability for such
infringement, which could be material. We could also be prohibited from using or selling certain subscriptions, prohibited from using certain processes, or required
to redesign certain subscriptions, each of which could have a material adverse effect on our business and results of operations.

These and other outcomes may:
•
•
•
•
•
•
•
•
•
•

result in the loss of a substantial number of existing customers or prohibit the acquisition of new customers;
cause us to pay license fees for intellectual property we are deemed to have infringed;
cause us to incur costs and devote valuable technical resources to redesigning our subscriptions;
cause our cost of revenues to increase;
cause us to accelerate expenditures to preserve existing revenues;
cause existing or new vendors to require pre-payments or letters of credit;
materially and adversely affect our brand in the marketplace and cause a substantial loss of goodwill;
cause us to change our business methods or subscriptions;
require us to cease certain business operations or offering certain subscriptions or features; and
lead to our bankruptcy or liquidation.

Our limited ability to protect our intellectual property rights could materially and adversely affect our business.

We rely, in part, on patent, trademark, copyright, and trade secret law to protect our intellectual property in the U.S. and abroad. We seek to protect our
technology, software, documentation and other information under trade secret and copyright law, which afford only limited protection. For example, we typically
enter into confidentiality agreements with our employees, consultants, third-party contractors, customers, and vendors in an effort to control access to, use of, and
distribution of our technology, software, documentation, and other information. These agreements may not effectively prevent unauthorized use or disclosure of
confidential information and may not provide an adequate remedy in the event of such unauthorized use or disclosure, and it may be possible for a third party to
legally reverse engineer, copy, or otherwise obtain and use our technology without authorization. In addition, improper disclosure of trade secret information by
our  current  or  former  employees,  consultants,  third-party  contractors,  customers,  or  vendors  to  the  public  or  others  who  could  make  use  of  the  trade  secret
information would likely preclude that information from being protected as a trade secret.

We also rely, in part, on patent law to protect our intellectual property in the U.S. and internationally. Our intellectual property portfolio includes over 262
issued  patents,  which  expire  between  2022  and  2039.  We  also  have  50  patent  applications  pending  examination  in  the  U.S.  and  7  patent  applications  pending
examination in foreign jurisdictions, all of which are related to U.S. applications. We cannot predict whether such pending patent applications will result in issued
patents or whether any issued patents will effectively protect our intellectual property. Even if a pending patent application results in an issued patent, the patent
may be circumvented or its validity may be challenged in various proceedings in United States District Court or before the U.S. Patent and Trademark Office, such
as Post Grant Review or Inter Partes Review, which may require legal

37

Table of Contents

representation  and  involve  substantial  costs  and  diversion  of  management  time  and  resources.  We  have  also  acquired  patents  in  connection  with  a  strategic
partnership that are currently pending assignment in their respective patent offices. In addition, we cannot assure you that every significant feature of our solutions
is protected by our patents, or that we will mark our solutions with any or all patents they embody. As a result, we may be prevented from seeking injunctive relief
or damages, in whole or in part for infringement of our patents.

The unlicensed use of our brand, including domain names, by third parties could harm our reputation, cause confusion among our customers and impair
our ability to market our solutions and subscriptions. To that end, we have registered numerous trademarks and service marks and have applied for registration of
additional trademarks and service marks and have acquired a large number of domain names in and outside the U.S. to establish and protect our brand names as
part of our intellectual property strategy. If our applications receive objections or are successfully opposed by third parties, it will be difficult for us to prevent third
parties  from  using  our  brand  without  our  permission.  Moreover,  successful  opposition  to  our  applications  might  encourage  third  parties  to  make  additional
oppositions or commence trademark infringement proceedings against us, which could be costly and time consuming to defend against. If we are not successful in
protecting our trademarks, our trademark rights may be diluted and subject to challenge or invalidation, which could materially and adversely affect our brand.

Despite  our  efforts  to  implement  our  intellectual  property  strategy,  we  may  not  be  able  to  protect  or  enforce  our  proprietary  rights  in  the  U.S.  or
internationally  (where  effective  intellectual  property  protection  may  be  unavailable  or  limited).  For  example,  we  have  entered  into  agreements  containing
confidentiality and invention assignment provisions in connection with the outsourcing of certain software development and quality assurance activities to third-
party contractors located in Russia and Ukraine. We have also entered into an agreement containing a confidentiality provision with a third-party contractor located
in the Philippines, where we have outsourced a significant portion of our customer support function. We cannot assure you that agreements with these third-party
contractors  or  their  agreements  with  their  employees  and  contractors  will  adequately  protect  our  proprietary  rights  in  the  applicable  jurisdictions  and  foreign
countries,  as their respective  laws may not protect proprietary  rights to the same extent as the laws of the U.S. In addition, our competitors  may independently
develop technologies that are similar or superior to our technology, duplicate our technology in a manner that does not infringe our intellectual property rights or
design around any of our patents. Furthermore, detecting and policing unauthorized use of our intellectual property is difficult and resource-intensive. Moreover,
litigation may be necessary in the future to enforce our intellectual  property rights, to determine the validity and scope of the proprietary rights of others, or to
defend against claims of infringement or invalidity. Such litigation, whether successful or not, could result in substantial costs and diversion of management time
and resources and could have a material adverse effect on our business, financial condition, and results of operations.

Our use of open source technology could impose limitations on our ability to commercialize our subscriptions.

We use open source software in our platform on which our subscriptions operate. There is a risk that the owners of the copyrights in such software may
claim that such licenses impose unanticipated conditions or restrictions on our ability to market or provide our subscriptions. If such owners prevail in such claim,
we could be required to make the source code for our proprietary software (which contains our valuable trade secrets) generally available to third parties, including
competitors, at no cost, to seek licenses from third parties in order to continue offering our subscriptions, to re-engineer our technology, or to discontinue offering
our subscriptions in the event re-engineering cannot be accomplished on a timely basis or at all, any of which could cause us to discontinue our subscriptions, harm
our reputation, result in customer losses or claims, increase our costs or otherwise materially and adversely affect our business and results of operations.

Risks Related to Our Class A Common Stock, Our Notes and Our Charter Provisions

The market price of our Class A Common Stock is likely to be volatile and could decline.

The stock market in general, and the market for SaaS and other technology-related stocks in particular, has been highly volatile. As a result, the market
price  and  trading  volume  for  our  Class  A  Common  Stock  has  been  and  may  continue  to  be  highly  volatile,  and  investors  in  our  Class  A  Common  Stock  may
experience a decrease in the value of their shares, including decreases unrelated to our operating performance or prospects. Factors that could cause the market
price of our Class A Common Stock to fluctuate significantly include:

•
•
•

our operating and financial performance and prospects and the performance of other similar companies;
our quarterly or annual earnings or those of other companies in our industry;
conditions that impact demand for our subscriptions;

38

Table of Contents

•

•
•
•
•
•
•
•
•
•

the  public’s  reaction  to  our  press  releases,  financial  guidance,  and  other  public  announcements,  and  filings  with  the  Securities  and  Exchange
Commission (the "SEC");
changes in earnings estimates or recommendations by securities or research analysts who track our Class A Common Stock;
actual or perceived security breaches, or other privacy or cybersecurity incidents;
market and industry perception of our success, or lack thereof, in pursuing our growth strategy;
strategic actions by us or our competitors, such as acquisitions or restructurings;
changes in government and other regulations;
changes in accounting standards, policies, guidance, interpretations, or principles;
arrival and departure of key personnel;
sales of common stock by us, our investors, or members of our management team; and
changes in general market, economic, and political conditions in the U.S. and global economies or financial markets, including those resulting from
natural disasters, telecommunications failure, cyber-attack, changes in diplomatic or trade relationships, civil unrest in various parts of the world,
acts of war, terrorist attacks, or other catastrophic events, such as the global outbreak of COVID-19.

Any  of  these  factors  may  result  in  large  and  sudden  changes  in  the  trading  volume  and  market  price  of  our  Class  A Common  Stock  and  may  prevent
investors from being able to sell their shares at or above the price they paid for their shares of our Class A Common Stock. Following periods of volatility in the
market  price of a company’s securities,  stockholders  often file securities  class-action  lawsuits against such company. Our involvement  in a class-action  lawsuit
could divert our senior management’s attention and, if adversely determined, could have a material and adverse effect on our business, financial condition, and
results of operations.

The dual class structure of our common stock as contained in our charter documents has the effect of concentrating voting control with a limited number of
stockholders  that  held  our  stock  prior  to  our  initial  public  offering,  including  our  founders  and  our  executive  officers,  employees  and  directors  and  their
affiliates, and venture capital investors, and limiting other stockholders’ ability to influence corporate matters.

Our Class B common stock, par value $0.0001 per share (“Class B Common Stock” and, together with our Class A Common Stock, our "common stock"),
has 10 votes per share, and our Class A Common Stock has one vote per share. Stockholders who hold shares of Class B Common Stock, including our founders,
previous investors and our executive officers, employees and directors and their affiliates, together hold approximately 56% of the voting power of our outstanding
capital  stock,  and  our  founders,  including  our  CEO  and  Chairman,  together  hold  a  majority  of  such  voting  power.  As  a  result,  for  the  foreseeable  future  ,  our
stockholders who acquired their shares prior to the completion of our initial public offering will continue to have significant influence over the management and
affairs  of  our  company  and  over  the  outcome  of  many  matters  submitted  to  our  stockholders  for  approval,  including  the  election  of  directors  and  significant
corporate transactions, such as a merger, consolidation or sale of substantially all of our assets.

In addition, because of the ten-to-one voting ratio between our Class B and Class A Common Stock, the holders of Class B Common Stock collectively
will continue to control many matters submitted to our stockholders for approval even if their stock holdings represent less than 50% of the outstanding shares of
our common stock. This concentrated control will limit your ability to influence corporate matters for the foreseeable future, and, as a result, the market price of
our Class A Common Stock could be adversely affected.

Future transfers by holders of Class B Common Stock will generally result in those shares converting to Class A Common Stock, which may have the
effect,  over  time,  of  increasing  the  relative  voting  power  of  those  holders  of  Class  B  Common  Stock  who  retain  their  shares  in  the  long  term.  If,  for  example,
Mr. Shmunis retains a significant portion of his holdings of Class B Common Stock for an extended period of time, he could, in the future, control a majority of the
combined voting power of our Class A and Class B Common Stock. As a board member, Mr. Shmunis owes fiduciary duties to our stockholders and must act in
good faith  in  a manner  he  reasonably  believes  to  be in  the  best  interests  of  our  stockholders.  As a  stockholder,  even  a  controlling  stockholder,  Mr.  Shmunis  is
generally entitled to vote his shares in his own interests, which may not always be in the interests of our stockholders generally.

We have never paid cash dividends and do not anticipate paying any cash dividends on our common stock.

We currently do not plan to declare dividends on shares of our common stock in the foreseeable future and plan to, instead, retain any earnings to finance
our operations and growth. Because we have never paid cash dividends and do not anticipate paying any cash dividends on our common stock in the foreseeable
future, the only opportunity to achieve a return on an investor’s investment in our company will be if the market price of our Class A Common Stock appreciates
and the investor sells its shares at a profit. There is no guarantee that the price of our Class A Common Stock that will prevail in the market will ever exceed the
price that an investor pays.

We may not have the ability to raise the funds necessary to settle conversions of the Notes in cash or to repurchase the Notes upon a fundamental change or
pay the principal amount of the Notes at maturity, and our future debt may contain limitations on our ability to pay cash upon conversion or repurchase of the
Notes.

Holders of the either series of Notes will have the right to require us to repurchase all or a portion of such Notes upon the occurrence of a fundamental
change before the applicable  maturity date at a repurchase price equal to 100% of the principal amount of such Notes to be repurchased,  plus any accrued and
unpaid special interest  thereon, if any, as set forth in the applicable  indenture  governing the Notes. In addition, upon conversion of the Notes of the applicable
series, unless we elect to deliver solely shares of our Class A 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 such Notes being converted, as set forth in the applicable indenture governing the Notes. Moreover,
we will be required to repay the Notes of the applicable series in cash at their respective maturity unless earlier converted, redeemed or repurchased. However, we
may not have enough available cash on hand or be able to obtain financing at the time we are required to make repurchases of such Notes surrendered therefor or
pay cash with respect to such series of Notes being converted or at their respective maturity.

In addition, our ability to repurchase the Notes of the applicable series or to pay cash upon conversions of the Notes or at their respective maturity may be
limited  by  law,  regulatory  authority,  or  agreements  governing  our  future  indebtedness.  Our  failure  to  repurchase  such  Notes  at  a  time  when  the  repurchase  is
required by the applicable indenture governing the Notes or to pay cash upon conversions of such Notes or at their respective maturity as required by the applicable
indenture governing the Notes would constitute a default under such indenture. A default under such indenture, or the fundamental change itself, could also lead to
a default under agreements governing our future indebtedness. Moreover, the occurrence of a fundamental change under the applicable indenture governing the
Notes could constitute an event of default under any such agreement. 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 such series of Notes or make cash payments upon conversions thereof.

The conditional conversion feature of each series of Notes, if triggered, may adversely affect our financial condition and operating results.

In the event the conditional conversion feature of each series of Notes is triggered, holders of the Notes of the applicable series will be entitled under the
applicable  indenture  governing  the  Notes  to  convert  such  Notes  at  any  time  during  specified  periods  at  their  option.  If  one  or  more  holders  of  a  series  elect  to
convert their Notes, unless we elect to satisfy our conversion obligation by delivering solely shares of our Class A 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 in cash, which could adversely affect our liquidity. In
addition,  in  certain  circumstances,  such  as  conversion  by  holders  or  redemption,  we  could  be  required  under  applicable  accounting  rules  to  reclassify  all  or  a
portion  of  the  outstanding  principal  of  such  series  of  Notes  as  a  current  rather  than  long-term  liability,  which  would  result  in  a  material  reduction  of  our  net
working capital.

The capped call transactions may affect the value of the Notes and our Class A Common Stock and we are subject to counterparty risk.

In connection with the issuances of the Notes, we entered into capped call transactions with the counterparties with respect to each series of Notes. The
capped call transactions cover, subject to customary adjustments, the number of shares of our Class A Common Stock initially underlying each series of Notes. The
capped call transactions are expected to offset the potential dilution as a result of conversion of the Notes.

The counterparties or their respective affiliates may modify their hedge positions by entering into or unwinding various derivatives with respect to our

Class A Common Stock and/or purchasing or selling our Class A Common Stock or

40

Table of Contents

other securities of ours in secondary market transactions at any time prior to the respective maturity of the Notes (and are likely to do so on each exercise date of
the capped call transactions). This activity could also cause or prevent an increase or a decrease in the market price of our Class A Common Stock.

We do not make any representation or prediction as to the direction or magnitude of any potential effect that the transactions described above may have on
the price of each series of Notes or the shares of our Class A Common Stock. In addition, we do not make any representation that these transactions will not be
discontinued without notice.

In  addition,  the  counterparties  to  the  capped  call  transactions  are  financial  institutions  and  we  will  be  subject  to  the  risk  that  one  or  more  of  the
counterparties  may  default  or  otherwise  fail  to  perform,  or  may  exercise  certain  rights  to  terminate,  their  obligations  under  the  capped  call  transactions.  If  a
counterparty to one or more capped call transaction becomes subject to insolvency proceedings, we will become an unsecured creditor in those proceedings with a
claim equal to our exposure at the time under such transaction. Our exposure will depend on many factors but, generally, it will increase if the market price or the
volatility of our Class A Common Stock increases. Upon a default or other failure to perform, or a termination of obligations, by a counterparty, we may suffer
adverse  tax  consequences  and  more  dilution  than  we  currently  anticipate  with  respect  to  our  Class  A  Common  Stock.  We  can  provide  no  assurances  as  to  the
financial stability or viability of the counterparties.

Anti-takeover  provisions  in  our  restated  certificate  of  incorporation  and  bylaws  and  under  Delaware  corporate  law  could  make  an  acquisition  of  us  more
difficult, limit attempts by our stockholders to replace or remove our current management and limit the market price of our Class A Common Stock.

Provisions in our certificate of incorporation and bylaws may have the effect of delaying or preventing a change of control or changes in our management.

Our certificate of incorporation and bylaws include provisions that:

•
•

•

•
•
•
•

•

authorize our board of directors to issue, without further action by the stockholders, up to 100,000,000 shares of undesignated preferred stock;
require that, once our outstanding shares of Class B Common Stock represent less than a majority of the combined voting power of our common
stock, any action to be taken by our stockholders be effected at a duly called annual or special meeting and not by written consent; specify that
special meetings of our stockholders can be called only by our board of directors, the Chairman of our board of directors, or our Chief Executive
Officer;
establish  an  advance  notice  procedure  for  stockholder  proposals  to  be  brought  before  an  annual  meeting,  including  proposed  nominations  of
persons for election to our board of directors;
prohibit cumulative voting in the election of directors;
provide that our directors may be removed only for cause, subject to such amendment as provided in our current proxy statement;
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;
require the approval of our board of directors or the holders of a supermajority of our outstanding shares of capital stock to amend our bylaws and
certain provisions of our certificate of incorporation; and
reflect two classes of common stock, as discussed above.

These provisions may frustrate or prevent any attempts by our stockholders to replace or remove our current management by making it more difficult for
stockholders  to  replace  members  of  our  board  of  directors,  which  is  responsible  for  appointing  the  members  of  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  generally  prohibits  a  Delaware
corporation from engaging in any of a broad range of business combinations with any “interested” stockholder for a period of three years following the date on
which the stockholder became an “interested” stockholder.

General Risk Factors

Changes  in  effective  tax  rates,  or  adverse  outcomes  resulting  from  examination  of  our  income  or  other  tax  returns,  could  adversely  affect  our  results  of
operations and financial condition.

Our future effective tax rates could be subject to volatility or adversely affected by a number of factors, including:
•
•
•

changes in the valuation of our deferred tax assets and liabilities;
expiration of, or lapses in, the research and development tax credit laws;
expiration or non-utilization of net operating loss carryforwards;

41

Table of Contents

•
•
•
•
•

tax effects of share-based compensation;
expansion into new jurisdictions;
potential challenges to and costs related to implementation and ongoing operation of our intercompany arrangements;
changes in tax laws and regulations and accounting principles, or interpretations or applications thereof; and
certain non-deductible expenses as a result of acquisitions.

Any changes in our effective tax rate could adversely affect our results of operations.

Changes in U.S. and foreign tax laws could have a material adverse effect on our business, cash flow, results of operations or financial conditions.

We  are  subject  to  tax  laws,  regulations,  and  policies  of  the  U.S.  federal,  state,  and  local  governments  and  of  comparable  taxing  authorities  in  foreign
jurisdictions.  Changes  in  tax  laws,  as  well  as  other  factors,  could  cause  us  to  experience  fluctuations  in  our  tax  obligations  and  effective  tax  rates  in  2018  and
thereafter and otherwise adversely affect our tax positions and/or our tax liabilities. For example, on July 25, 2019, France introduced a digital services tax at a rate
of 3% on revenues derived from digital activities in France, and other jurisdictions are proposing or could introduce similar laws in the future. There can be no
assurance that our effective tax rates, tax payments, tax credits, or incentives will not be adversely affected by these or other initiatives.

If our internal control over financial reporting is not effective, it may adversely affect investor confidence in our company.

Pursuant  to  Section  404  of  the  Sarbanes-Oxley  Act,  our  independent  registered  public  accounting  firm,  KPMG  LLP,  is  required  to  and  has  issued  an
attestation  report  as  of  December  31,  2020.  While  management  concluded  internal  control  over  financial  reporting  was  at  a  reasonable  assurance  level  as  of
December 31, 2020, there can be no assurance that material weaknesses will not be identified in the future. A “material weakness” is a deficiency, or a combination
of deficiencies, in internal control over financial reporting such that there is a reasonable possibility that a material misstatement of our annual or interim financial
statements will not be prevented or detected on a timely basis. During the evaluation and testing process, if we identify one or more material weaknesses in our
internal control over financial reporting, we will be unable to assert that our internal controls are effective. As a result, we may need to undertake various actions,
such  as  implementing  new  internal  controls  and  procedures  and  hiring  accounting  or  internal  audit  staff.  Our  remediation  efforts  may  not  enable  us  to  avoid  a
material weakness in the future.

If our independent registered public accounting firm is unable to express an opinion on the effectiveness of our internal controls, we could lose investor
confidence in the accuracy and completeness of our financial reports, which could cause the price of our Class A Common Stock to decline, and we may be subject
to investigation or sanctions by the SEC.

The nature of our business requires the application of complex revenue and expense recognition rules and the current legislative and regulatory environment
affecting generally accepted accounting principles is uncertain. Significant changes in current principles could affect our financial statements going forward
and changes in financial accounting standards or practices may cause adverse, unexpected financial reporting fluctuations and harm our operating results.

The accounting rules and regulations that we must comply with are complex and subject to interpretation by the Financial Accounting Standards Board
(the “FASB”), the SEC and various bodies formed to promulgate and interpret appropriate accounting principles. Recent actions and public comments from the
FASB and the SEC have focused on the integrity of financial reporting and internal controls. In addition, many companies’ accounting policies are being subject to
heightened scrutiny by regulators and the public. Further, the accounting rules and regulations are continually changing in ways that could materially impact our
financial statements.

We cannot predict the impact of future changes to accounting principles or our accounting policies on our financial statements going forward, which could
have a significant effect on our reported financial results and could affect the reporting of transactions completed before the announcement of the change. Due to
the COVID-19 pandemic, there is ongoing uncertainty and significant disruption in the global economy and financial markets, and while we are not aware of any
specific event or circumstance that would require a material update to our estimates, judgments or assumptions, this may change in the future. In addition, if we
were to change our critical accounting estimates, including those related to the recognition of subscription revenue and other revenue sources, our operating results
could be significantly affected.

Our  corporate  headquarters,  one  of  our  data  centers  and  co-location  facilities,  our  third-party  customer  service  and  support  facilities,  and  a  research  and
development  facility  are  located  near  known  earthquake  fault  zones,  and  the  occurrence  of  an  earthquake,  tsunami,  or  other  catastrophic  disaster  could
damage our facilities or the facilities of our contractors, which could cause us to curtail our operations.

Our  corporate  headquarters  and  many  of  our  data  centers,  co-location  and  research  and  development  facilities,  and  third-party  customer  service  call
centers are located in California, Florida, and several countries in Asia, including the Philippines and Australia. All of these locations are near known earthquake
fault zones, which are vulnerable to damage from earthquakes and tsunamis, or are in areas subject to hurricanes. We and our contractors are also vulnerable to
other  types  of  disasters,  such  as  power  loss,  fire,  floods,  pandemics  such  as  the  global  outbreak  of  COVID-19,  cyber-attack,  war,  political  unrest,  and  terrorist
attacks and similar events that are beyond our control. If any disasters were to occur, our ability to operate our business could be seriously impaired, and we may
endure  system  interruptions,  reputational  harm,  loss  of  intellectual  property,  delays  in  our  subscriptions  development,  lengthy  interruptions  in  our  services,
breaches of data security, and loss of critical data, all of which could harm our future results of operations. In addition, we do not carry earthquake insurance and
we may not have adequate insurance to cover our losses resulting from other disasters or other similar significant business interruptions. Any significant losses that
are not recoverable under our insurance policies could seriously impair our business and financial condition.

If research analysts do not publish research or reports about our business, or if they issue unfavorable commentary or downgrade our Class A Common Stock,
our stock price and trading volume may decline.

The  trading  market  for  our  Class  A  Common  Stock  will  depend  in  part  on  the  research  and  reports  that  research  analysts  publish  about  us  and  our
business. If we do not maintain adequate research coverage or if one or more analysts who covers us downgrades our stock or publishes inaccurate or unfavorable
research about our business, the price of our Class A Common Stock may decline. If one or more of the research analysts ceases coverage of our company or fails
to publish reports on us regularly, demand for our Class A Common Stock may decrease, which could cause our stock price or trading volume to decline.

ITEM 1B.    UNRESOLVED STAFF COMMENTS

None.

ITEM 2.    PROPERTIES

Our corporate headquarters is located in Belmont, California, and consists of approximately 110,000 square feet of office space under leases that expire in

July 2026.

We  also  lease  offices  in  Denver,  Colorado;  Charlotte,  North  Carolina;  Fort  Lauderdale,  Florida;  London,  England;  Xiamen,  China;  Paris,  France;  and
other  small  offices  worldwide.  In  addition,  we  lease  space  from  third-party  datacenter  hosting  facilities  under  co-location  agreements  that  support  our  cloud
infrastructure,  the  most  significant  locations  being  Vienna  and  Ashburn,  Virginia;  San  Jose  and  Santa  Clara,  California;  Chicago,  Illinois;  Amsterdam,  the
Netherlands; Zurich, Switzerland; Frankfurt, Germany; and other small locations worldwide. We believe that we will be able to obtain additional space at other
locations at commercially reasonable terms to support our continuing expansion.

ITEM 7.    MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion of our financial condition and results of operations should be read in conjunction with the consolidated financial statements and
notes thereto included elsewhere in this Annual Report on Form 10-K. As discussed in the section entitled “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 significantly  from those expressed or implied by such forward-looking statements. Factors that
could cause or contribute to these differences include, but are not limited to, those discussed below and elsewhere in this report, particularly in the section entitled
“Risk Factors” included under Part I, Item1A.

This section of this Form 10-K generally discusses 2020 and 2019 items and year-to-year comparisons between 2020 and 2019. Discussion regarding our
financial condition and results of operations for fiscal 2019 as compared to fiscal 2018 is included in Item 7 of our Annual Report on Form 10-K for the year
ended December 31, 2019, filed with the SEC on February 26, 2020.

Overview

We  are  a  leading  provider  of  cloud  communications,  video  meetings,  collaboration,  and  contact  center  software-as-a-service  (“SaaS”)  solutions.  We
believe that our innovative, cloud-based communication and contact center solutions disrupt the large market for business communications and collaboration by
providing  flexible  and  cost-effective  solutions  that  support  mobile  and  distributed  workforces.  We  enable  convenient  and  effective  communications  for
organizations across all their locations and employees, enabling them to be more productive and more responsive to their customers.

Our  cloud-based  business  communications  and  collaboration  solutions  are  designed  to  be  easy  to  use,  providing  a  single  user  identity  across  multiple
locations and devices, including smartphones, tablets, PCs and desk phones. Our solutions can be deployed rapidly and configured and managed easily. Through
our  platform,  we  enable  third-party  developers  and  customers  to  integrate  our  solution  with  leading  business  applications  to  customize  their  own  business
workflows.

We have a portfolio of cloud-based offerings that are subscription based, made available at different rates varying by the specific functionalities, services,
and number of users. We primarily generate revenues from the sale of subscriptions to our offerings. Our subscription plans have monthly, annual, or multi-year
contractual terms. We believe that this flexibility in contract duration is important to meet the different needs of our customers. For the years ended December 31,
2020,  2019,  and  2018,  subscriptions  revenues  accounted  for  90%  or  more  of  our  total  revenues.  The  remainder  of  our  revenues  has  historically  been  primarily
comprised of product revenues from the sale and rental of pre-configured phones and professional services. We do not develop, manufacture, or otherwise touch
the delivery of physical phones and offer it as a convenience for a total solution to our customers in connection with subscriptions to our services. We rely on third-
party providers to develop and manufacture these devices and fulfillment partners to successfully serve our customers.

We continue to invest in our direct inside sales force while also developing indirect sales channels to market our brand and our subscription offerings. Our

indirect sales channels who sell our solutions consist of:

•

•

•

 a regional and global network of resellers;

carriers including AT&T, Inc. (“AT&T”), TELUS Communications Company (“TELUS”), and BT Group plc (“BT”). Also, in November 2020
we  entered  into  a  strategic  partnership  with  Vodafone  Group  Services  Limited  ("Vodafone")  to  deliver  new  cloud-based  communications
services.  The  parties  will  introduce  a  new  co-branded  cloud-based  service  that  will  be  the  Unified  Communications  as  a  Service  ("UCaaS")
solution for Vodafone and a Contact Center as a Service ("CCaaS") solution to Vodafone customers;

strategic  partners  who  market  and  sell  our  co-branded  solutions  directly  and  through  their  subsidiaries.  Such  partnerships  include  Avaya
Holdings Corp. ("Avaya"), under which we introduced a new solution Avaya Cloud Office by RingCentral ("ACO") in March 2020; Atos SE
("Atos")  and  its  subsidiary,  Unify  Software  and  Solutions  GmbH  &  CO.  KG  ("Unify"),  under  which  we  introduced  a  new  Unified
Communications as a Service ("UCaaS") solution called Unify Office by RingCentral ("UO") in September 2020; and in July 2020, we entered
into a strategic partnership with Alcatel-Lucent Enterprise ("ALE"), which includes the introduction of a new co-branded solution which will be
marketed and sold as the UCaaS solution offering of ALE beginning in 2021.

Since its launch, our revenue growth has primarily been driven by our flagship RingCentral Office product offering, which has resulted in an increased

number of customers, increased average subscription revenue per customer, and increased

47

Table of Contents

retention  of  our  existing  customer  and  user  base.  We  define  a  “customer”  as  any  party  that  purchases  or  subscribes  to  our  products  and  services  directly  or
indirectly through our channel partners. As of December 31, 2020, we had customers from a range of industries, including financial services, education, healthcare,
legal services, real estate, retail, technology, insurance, construction, hospitality, and state and local government, among others. For the years ended December 31,
2020,  2019  and  2018,  the  vast  majority  of  our  total  revenues  were  generated  in  the  U.S.  and  Canada,  although  we  expect  the  percentage  of  our  total  revenues
derived outside of the U.S. and Canada to grow as we continue to expand internationally.

The  growth  of  our  business  and  our  future  success  depend  on  many  factors,  including  our  ability  to  expand  our  customer  base  to  larger  customers,
expansion  of  our  indirect  sales  channels  including  strategic  partnerships,  continue  to  innovate,  grow  revenues  from  our  existing  customer  base,  expand  our
distribution channels, and scale internationally.

In December 2019, a novel strain of coronavirus (“COVID-19”) was reported and in January 2020, the World Health Organization (the "WHO") declared
the outbreak a “Public Health Emergency of International Concern.” In February 2020, the WHO raised the COVID-19 threat level from high to very high at a
global  level  and  in  March  2020,  the  WHO  characterized  the  COVID-19  as  a  pandemic.  The  worldwide  spread  of  COVID-19  has  resulted  in  authorities
implementing  numerous  measures  to  contain  the  virus,  including  travel  bans  and  restrictions,  quarantines,  shelter-in-place  orders,  and  business  limitations  and
shutdowns.

During the year ended December 31, 2020, we noted contributions from new bookings as more businesses transition to RingCentral in the current work-
from-anywhere environment. In the first and early part of the second quarter, we experienced higher churn rate mainly with small business customers in certain
verticals. Since then we have seen stabilization in churn levels. Due to the shelter-in-place, we continue to see more customers opting for the RingCentral apps on
laptops  and  mobile  devices  over  traditional  desktop  phones  which  has  impacted  demand  for  physical  phone  devices.  We  also  observed  customer  requests  for
extension in payment terms. To address customer hardships, we continue to engage with these customers providing them greater flexibility to manage challenges
they are facing.

While our revenues and earnings are relatively predictable as a result of our subscription-based business model, the effect of the COVID-19 pandemic,
may  not  be  fully  reflected  in  our  results  of  operations  and  overall  financial  performance  until  future  periods.  The  COVID-19  pandemic  has  created  a  global
slowdown  of  economic  activity  which  has  and  will  likely  continue  to  decrease  demand  for  a  broad  variety  of  goods  and  services,  while  also  disrupting  sales
channels and marketing activities for an unknown period of time until the disease is contained.

We  may  experience  curtailed  customer  demand  due  to  reduced  customer  spend,  shortened  contract  duration,  higher  churn,  lengthened  payment  terms,
credit  card  declines,  potential  delays  in  professional  services  implementations,  and  reduction  in  demand  for  desktop  phones,  which  could  adversely  impact  our
business, results of operations and overall financial performance in future periods. We may in the future continue to experience elevated churn in certain customer
verticals and customer requests for extension of payment terms.

The extent of the impact of the COVID-19 pandemic on our operational and financial performance will also depend on certain developments, including
the duration and spread of the outbreak, actions taken to contain the virus or its impact, impact on our partners, resellers, employees, vendors and customers, and
employee or industry events, all of which are uncertain and cannot be predicted. For example, to support the health and well-being of our employees, customers,
partners  and  communities  in  response  to  the  COVID-19  pandemic,  a  vast  majority  of  our  employees  are  working  remotely  and  we  have  shifted  some  of  our
customer events to virtual-only experiences, and we may deem it advisable to similarly alter, postpone or cancel entirely additional customer, employee or industry
events in the future. At this point, the full extent to which the COVID-19 pandemic may impact our financial condition or results of operations is uncertain, but
changes we have implemented have not affected and are not expected to affect our ability to maintain operations, including financial reporting systems, internal
control over financial reporting, and disclosure controls and procedures.

Further discussion of the potential impacts of the COVID-19 pandemic on our business can be found in the section titled "Risk Factors" included in Part I,

Item 1A.

Key Business Metrics

In addition to United States generally accepted accounting principles (“U.S. GAAP”) and financial measures such as total revenues, gross margin, and
cash  flows  from  operations,  we  regularly  review  a  number  of  key  business  metrics  to  evaluate  growth  trends,  measure  our  performance,  and  make  strategic
decisions. We discuss revenues and gross margin under “Results of Operations”, and cash flow from operations and free cash flows under “Liquidity and Capital
Resources.” Other key business metrics are discussed below.

Annualized Exit Monthly Recurring Subscriptions

We  believe  that  our  Annualized  Exit  Monthly  Recurring  Subscriptions  (“ARR”)  is  a  leading  indicator  of  our  anticipated  subscriptions  revenues.  We
believe that trends in revenue are important to understanding the overall health of our business, and we use these trends in order to formulate financial projections
and make strategic business decisions. Our ARR equals our Monthly Recurring Subscriptions multiplied by 12. Our Monthly Recurring Subscriptions equals the
monthly value of all customer recurring charges at the end of a given month. For example, our Monthly Recurring Subscriptions at December 31, 2020 was $108.3
million. As such, our ARR at December 31, 2020 was $1.3 billion compared to $960.1 million at December 31, 2019.

RingCentral Office Annualized Exit Monthly Recurring Subscriptions

We calculate our RingCentral Office Annualized Exit Monthly Recurring Subscriptions (“Office ARR”) in the same manner as we calculate our ARR,
except that primarily customer subscriptions from RingCentral Office and RingCentral customer engagement solutions customers are included when determining
Monthly  Recurring  Subscriptions  for  the  purposes  of  calculating  this  key  business  metric.  We  believe  that  trends  in  revenue  with  respect  to  these  products  are
important to the understanding of the overall health of our business, and we use these trends in order to formulate financial projections and make strategic business
decisions. Our Office ARR at December 31, 2020 was $1.2 billion compared to $876.8 million at December 31, 2019.

Net Monthly Subscription Dollar Retention Rate

We believe that our Net Monthly Subscription Dollar Retention Rate provides insight into our ability to retain and grow subscriptions revenue, as well as
our customers’  potential  long-term  value to us. We believe  that our ability  to retain  our customers  and expand their  use of our solutions over time is a leading
indicator of the stability of our revenue base and we use these trends in order to formulate financial projections and make strategic business decisions. We define
our Net Monthly Subscription Dollar Retention Rate as (i) one plus (ii) the quotient of Dollar Net Change divided by Average Monthly Recurring Subscriptions.

We  define  Dollar  Net  Change  as  the  quotient  of  (i)  the  difference  of  our  Monthly  Recurring  Subscriptions  at  the  end  of  a  period  minus  our  Monthly
Recurring Subscriptions at the beginning of a period minus our Monthly Recurring Subscriptions at the end of the period from new customers we added during the
period, all divided by (ii) the number of months in the period. We define our Average Monthly Recurring Subscriptions as the average of the Monthly Recurring
Subscriptions at the beginning and end of the measurement period.

For example, if our Monthly Recurring Subscriptions were $118 at the end of a quarterly period and $100 at the beginning of the period, and $20 at the
end of the period from new customers we added during the period, then the Dollar Net Change would be equal to ($0.67), or the amount equal to the difference of
$118 minus $100 minus $20, all divided by three months. Our Average Monthly Recurring Subscriptions would equal $109, or the sum of $100 plus $118, divided
by two. Our Net Monthly Subscription Dollar Retention Rate would then equal 99.4%, or approximately 99%, or one plus the quotient of the Dollar Net Change
divided by the Average Monthly Recurring Subscriptions.

Our key business metrics for the five quarterly periods ended December 31, 2020 were as follows (dollars in millions):

Our revenues for the years presented consisted of subscriptions and other revenues. Our subscriptions revenue includes all fees billed in connection with
subscriptions  to  our  solution  offerings.  These  fees  include  recurring  fixed  plan  subscription  fees,  variable  usage-based  fees  for  usage  in  excess  of  plan  limits,
recurring  administrative  cost  recovery  fees,  one-time  fees,  and  other  recurring  fees  related  to  our  subscriptions.  We  provide  our  subscriptions  to  our  customers
pursuant to contractual arrangements that range in duration typically from one month to five years. We provide our subscriptions to our customers

49

Table of Contents

pursuant to either “click through” online agreements for service terms up to one year or written agreements when the arrangement is expected to be one year or
longer.  We  offer  our  subscriptions  based  on  the  functionalities  and  services  selected  by  a  customer,  and  generally  our  subscription  arrangements  automatically
renew for additional periods at the end of the initial subscription term. We believe that this flexibility in contract duration is important to meet the different needs of
our customers.

We  generally  bill  our  subscription  fees  in  advance.  We  recognize  subscription  revenue  over  the  term  of  the  agreement.  Amounts  billed  in  excess  of

revenue recognized for the period are reported as deferred revenue on our Consolidated Balance Sheets.

We  also  generate  revenues  through  sales  of  our  subscriptions  and  products  by  resellers,  strategic  partners,  and  carrier  partners.  When  we  control  the
performance  of  the  contractual  obligations,  we  record  the  revenues  on  a  gross  basis  and  amounts  retained  by  our  resellers  are  recorded  as  sales  and  marketing
expense. Our assumption of such control is evidenced  when, among other things, we are primarily  responsible  for the delivery  of the service  or products, have
inventory risk, and have discretion in establishing pricing of the arrangement.

“Other  revenues”  includes  product  revenues  from  the  sale  of  pre-configured  phones,  phone  rentals,  and  professional  services.  Product  revenue  is

recognized when the product has been delivered to the customer. Professional services revenue is recognized as services are delivered.

Cost of Revenues and Gross Margin

Our cost of subscriptions revenue primarily consists of fees paid to third-party telecommunications providers, network operations, costs to build out and
maintain data centers, including co-location fees for the right to place our servers in data centers owned by third parties, depreciation of servers and equipment,
along with related utilities and maintenance costs, personnel costs associated with customer care and support of the functionality of our platform and data center
operations, including share-based compensation expenses, and allocated costs of facilities and information technology.

We  define  subscriptions  gross  margins  as  subscriptions  revenue  minus  the  cost  of  subscriptions  revenue  expressed  as  a  percentage  of  subscriptions

revenue.

Cost  of  other  revenue  is  comprised  primarily  of  the  cost  associated  with  the  purchase  of  phones,  cost  of  professional  services,  and  allocated  costs  of

facilities and information technology.

Operating Expenses

We classify our operating expenses as research and development, sales and marketing, and general and administrative expenses.

Our research  and  development  efforts  are  focused  on  developing  new and  expanded  features  for our  solutions,  integrations  with  distributors  and  other
software platforms, and improvements  to our backend architecture.  Research and development expenses consist primarily of personnel costs for employees and
contractors, including share-based compensation expenses, and allocated costs of facilities and information technology, software tools, and product certification.
We expense research and development costs as incurred, except for certain internal-use software development costs that we capitalize. We believe that continued
investment in our products is important for our future growth, and we expect our research and development expenses to continue to increase in absolute dollars for
the  foreseeable  future,  although  these  expenses  may  fluctuate  as  a  percentage  of  our  total  revenues  from  period  to  period  depending  on  the  timing  of  these
expenses.

Sales and marketing expenses are the largest component of our operating expenses and consist primarily of personnel costs for employees and contractors
directly associated with our sales and marketing activities including share-based compensation expenses, internet advertising fees, radio and billboard advertising,
public  relations,  commissions  paid  to  employees,  resellers  and  other  third  parties,  amortization  of  capitalized  sales  commissions,  trade  shows,  travel  expenses,
credit card fees, marketing and promotional activities, amortization of acquired customer relationship intangibles, and allocated costs of facilities and information
technology. We expect our sales and marketing expenses to continue to increase in absolute dollars for the foreseeable future as we expand our sales and marketing
efforts domestically and internationally and continue to build our brand, although these expenses may fluctuate as a percentage of our total revenues from period to
period depending on the timing of these expenses.

General and administrative expenses consist primarily of personnel costs, including share-based compensation expenses, for employees and contractors

engaged in infrastructure and administrative activities to support the day-to-day

50

Table of Contents

operations of our business. Other significant components of general and administrative expenses include professional service fees, allocated costs of facilities and
information technology, cost of compliance with certain government-imposed taxes, the costs of legal matters, business acquisition costs, and loss contingencies.
We expect our general and administrative expenses to continue to increase in absolute dollars for the foreseeable future, although these expenses may fluctuate as a
percentage of our total revenues from period to period, depending on the timing of these expenses.

Subscriptions revenue.  Subscriptions revenue increased by $268.5 million, or 33%, during fiscal year 2020 as compared to fiscal year 2019. The increase
was  primarily  a  combination  of  the  acquisition  of  new  customers  and  upsells  of  seats  and  additional  offerings  to  our  existing  customer  base.  This  growth  was
primarily driven by an increase in sales to our mid-market and enterprise customers as we continue to move up market and increased sales through our direct and
indirect sales channels. Although we expect to continue to add new customers and for existing customers to increase their usage of our product, we will continue to
monitor the COVID-19 pandemic carefully and its impact on customer demand, contract duration, churn, payment terms, and credit card declines. Fluctuations in
foreign currency exchange rates and volatility in the market, including those resulting from the COVID-19 pandemic, could also cause variability in our revenue.

Table of Contents

Other revenues.   Other  revenues  are  primarily  comprised  of  product  revenue  from  the  sale  of  pre-configured  phones,  phone  rentals,  and  professional

services.

Other revenue increased by $12.3 million, or 15%, during fiscal year 2020 as compared to fiscal year 2019, primarily due to the increase in product sales
and professional services resulting from the overall growth in our business. Due to shelter in place restrictions adopted in many jurisdictions in response to the
COVID-19 pandemic, we continued to see a shift towards using RingCentral apps on laptops and mobile devices over traditional desktop phones and timing of
professional  services  projects.  We  may  see  a  reduction  in  demand  for  desktop  phones  and  slower  implementation  services.  We  will  continue  to  monitor  the
COVID-19 pandemic carefully and its impact on phone and professional services revenue.

Subscription cost of revenues and gross margin.  Cost of subscriptions revenues increased by $76.7 million, or 48%, during fiscal year 2020 as compared
to fiscal year 2019. The primary drivers of the increase were third-party costs to support our solution offerings of $25.9 million, amortization of acquired intangible
assets of $25.1 million, infrastructure support costs of $16.7 million, and personnel and contractor-related costs including share-based compensation expenses of
$11.7 million. Gross margin decreased mainly due to timing of acquisition of intangible assets which resulted in higher amortization of acquired intangible assets
of $25.1 million and timing of our equity grants which resulted in higher share-based compensation expense of $3.6 million.

The  increase  in  headcount  and  other  expense  categories  described  herein  was  driven  primarily  by  investments  in  our  infrastructure  and  capacity  to
improve the availability of our subscription offerings, while also supporting the growth in new customers and increased usage of our subscriptions by our existing
customer  base.  We  expect  subscription  gross  margin  to  be  within  a  relatively  similar  range  in  the  future.  However,  we  continue  to  monitor  the  COVID-
19 pandemic carefully and its impact on our customers.

Other cost of revenues and gross margin. Cost of other revenues increased by $15.9 million, or 22%, during fiscal year 2020 as compared to fiscal year
2019. This was primarily due to the increase in personnel costs including share-based compensation expense of $10.1 million and cost of product sales of $5.4
million. Other revenue gross margin fluctuated based on timing of completion of professional services projects and transaction price for product sales.

We continue to monitor the impact of the COVID-19 pandemic on timing of professional services and transaction price of product sales.

Research and development expenses increased by $53.1 million, or 39%, during fiscal year 2020 as compared to fiscal year 2019, primarily due to $48.0
million increase in personnel and contractor costs and $4.9 million increase in overhead costs to support our research and development efforts. The increase in
personnel  and  contractor  costs  was  mainly  driven  by  approximately  $30.3  million  relating  to  headcount  growth  and  $16.2  million  share-based  compensation
expense.

The increases in research and development headcount and other expense categories were driven by continued investment in current and future software
development  projects  for  our  applications.  Given  the  continued  emphasis  and  focus  on  product  innovation,  we  expect  research  and  development  expenses  to
continue to increase in absolute dollars.

Sales and marketing expenses increased by $144.7 million, or 33%, during fiscal year 2020 as compared to fiscal year 2019, primarily due to increases in
personnel and contractor costs of $73.3 million, third-party commissions of $35.2 million, advertising and marketing costs of $35.1 million, and amortization of
deferred  sales  commission  costs of $17.1 million,  partially  offset  by a $9.9 million  decrease  in travel  costs resulting  from  the impact  of COVID-19 and a $6.6
million  decrease  in  professional  fees  mainly  due  to  costs  associated  with  strategic  partnerships  and  acquisitions  in  fiscal  year  2019.  Of  the  total  increase  in
personnel and contractor costs, $45.5 million was primarily due to headcount growth and approximately $25.9 million was due to higher share-based compensation
expense.

The increases in sales and marketing headcount and other expense categories were necessary to support our growth strategy to acquire new customers
with a focus on larger customers, and to establish brand recognition to achieve greater penetration into the North America and international markets. Additionally,
we  expect  sales  and  marketing  expenses  to  continue  to  increase  in  absolute  dollars  as  we  continue  to  expand  our  presence  in  North  America  and  international
markets.

General  and  administrative  expenses  increased  by  $58.0  million,  or  41%,  during  fiscal  year  2020  as  compared  to  fiscal  year  2019,  primarily  due  to
increases in personnel and contractor costs of $51.1 million including $40.6 million due to higher share-based compensation expense, business fees and taxes of
$6.4  million,  overhead  costs  of  $3.9  million,  professional  fees  of  $3.2  million,  and  increased  allowance  for  doubtful  accounts  of  $3.0  million  partly  driven  by
customer collection related matters stemming form COVID-19, partially offset by cost savings of $10.0 million including credits and decreased travel costs.

We expect general and administrative expenses to continue to increase in absolute dollars as we continue to make additional investments in processes,

systems, and personnel to support our anticipated revenue growth.

Other income (expense), net increased by $42.4 million during fiscal year 2020 as compared to fiscal year 2019.

Other  income,  net  was  higher  by  $71.2  million  primarily  due  to  $81.1  million  net  unrealized  gain  recognized  on  our  long-term  investments,  which
depends  on  market  fluctuations,  partially  offset  by  $13.3  million  loss  on  partial  repurchase  of  our  convertible  senior  notes  during  fiscal  2020  and  decrease  in
interest income on our investments of $9.1 million mainly as a result of reduction in interest rates. Fiscal 2019 expense were also higher due to costs associated
with strategic partnerships and acquisitions of $10.6 million, which did not recur in fiscal 2020.

Interest expense was higher by $28.8 million due to increase in the amortization of debt discount and issuance costs from our 2025 and 2026 convertible

senior notes issued in the first and third quarters of 2020, respectively.

We expect interest income to further reduce in the future due to interest rate volatility in the current macroeconomic environment.

Net loss

Net  loss  increased  by  $29.4  million  during  fiscal  year  2020,  mainly  due  to  non-cash  items  including  $88.2  million  higher  share-based  compensation
expense  primarily  driven  by  equity  awards  granted  to  new  employees  and  annual  merit  based  equity  awards  to  existing  employees,  $28.7  million  increase  in
interest expense from the amortization of debt discount and issuance costs from our convertible senior notes, and $25.1 million increase in amortization of acquired
intangibles, partially offset by $81.1 million net unrealized gain recognized from our long-term investments, and a decrease in acquisition-related costs of $24.0
million.

Liquidity and Capital Resources

Liquidity is a measure of our ability to access sufficient cash flows to meet the short-term and long-term cash requirements of our business operations.

As of December  31, 2020 and 2019,  we had  cash and  cash  equivalents  of $639.9  million  and  $343.6 million,  respectively.  We  finance  our  operations
primarily  through  sales  to  our  customers,  which  could  be  billed  either  on a  monthly  or  annually  one  year  in  advance.  For customers  with  annual  or  multi-year
contracts and those who opt for annual invoicing, we generally invoice only one annual period in advance and revenue is deferred for such advanced billings. We
also finance our operations from proceeds from issuance of convertible senior notes and proceeds from issuance of stock under our stock plans.

In  March  2020,  we  issued  $1.0  billion  aggregate  principal  of  0%  convertible  senior  notes  due  2025  (the  “2025  Notes”)  in  a  private  placement.  As  of
December  31,  2020,  the  carrying  value  of  our  2025  Notes  totaled  $825.0  million.  In  September  2020,  we  issued  $650.0  million  aggregate  principal  of  0%
convertible  senior  notes  due  2026  (the  "2026  Notes")  in  a  private  placement.  As  of  December  31,  2020,  the  carrying  value  of  our  2026  Notes  totaled  $510.3
million. Our 2025 Notes and 2026 Notes contain customary financial covenants. In connection with both these offering, we used approximately $1.0 billion of the
total net proceeds of $1.6 billion to repurchase a portion of the 0% convertible senior notes due 2023 (the "2023 Notes").

The  2023  Notes  outstanding  principal  balance  as  of  December  31,  2020  was  $80.2  million,  out  of  which  $34.9  million  conversion  requests  were
outstanding  as  of  December  31,  2020,  and  we  received  additional  conversion  requests  of  $4.1  million  subsequent  to  December  31,  2020.  We  expect  to  pay
approximately $185 million in the first quarter of 2021 to settle these outstanding conversion requests. As of the filing date, the remaining outstanding principal
balance of the 2023 Notes is $45.3 million. We intend to settle this outstanding principal amount out of our cash and cash equivalents outstanding balance. For
additional  details,  refer  to  Note  6  –  Convertible  Senior  Notes of  the  notes  to  the  consolidated  financial  statements  included  in  Part  II,  Item  8,  “Consolidated
Financial Statements and Supplementary Data” of this Annual Report on Form 10-K for additional information. We are in compliance with all covenants under the
2026, 2025 and 2023 Notes as of December 31, 2020.

During the year ended December 31, 2020, we entered into strategic partnership agreements with ALE and Vodafone under which we paid approximately
$163.7  million.  We  also  financed  approximately  $4.7  million  of  property,  equipment,  and  software  licenses  through  vendor  financing  arrangements  and  paid
approximately $4.5 million to purchase additional intellectual property rights.

We believe that our operations, existing liquidity sources as well as capital resources and ability to raise cash through additional financing will satisfy our
future cash requirements and obligations for at least the next 12 months. Our future capital requirements will depend on many factors, including revenue growth
and costs incurred to support customer growth, acquisitions and expansions, sales and marketing, research and development, increased general and administrative
expenses to support the anticipated growth in our operations, and capital equipment required to support our growing headcount and in support of our co-location
data center facilities, as well as the extent of the COVID-19 pandemic and its effect on our business. Our capital expenditures in future periods are expected to
grow in line with our business. We continually evaluate our capital needs and may decide to raise additional capital to fund the growth of our business for general
corporate  purposes  through  public  or  private  equity  offerings  or  through  additional  debt  financing.  We  also  may  in  the  future  make  investments  in  or  acquire
businesses or technologies that could require us to seek additional equity or debt financing. Access to additional capital may not be available or on favorable terms.
The uncertainty created by the changing markets and economic conditions related to the COVID-19 pandemic may also impact our customers’ ability to pay on a
timely basis, which could negatively impact our operating cash flows.

Cash  used  in  or  provided  by  operating  activities  is  driven  by  our  net  loss,  the  timing  of  customer  collections,  as  well  as  the  amount  and  timing  of
disbursements to our vendors, the amount of cash we invest in personnel, marketing, and infrastructure  costs to support the anticipated  growth of our business,
payments under strategic arrangements, and amounts attributable to repayment of convertible notes.

Net cash used in operating activities was $35.2 million for the year ended December 31, 2020. This was driven primarily by $141.6 million paid under
strategic agreements and $35.0 million attributable to debt discount on a portion of the 2023 convertible senior notes that was repaid. These were offset by $141.4
million  in cash flow from operating  activities  during the year ended December  31, 2020. The cash flow from operating  activities  was driven by timing of cash
receipts and prepayments from customers and carriers and cash payments for personnel related costs and to vendors.

Net cash used in operating activities for the year ended December 31, 2020, increased by $100.0 million as compared to the year ended December 31,
2019. This change was driven by payments under strategic arrangements and debt discount for a portion of the 2023 senior convertible notes that was repaid, offset
with the additional cash generated from operating activities.

Net Cash Used in Investing Activities

Our  primary  investing  activities  have  consisted  of  our  long-term  investments,  business  acquisitions  and  purchase  of  intellectual  properties,  and  capital

expenditures and internal-use software. As our business grows, we expect our capital expenditures to continue to increase.

Net cash used in investing activities was $107.7 million for the year ended December 31, 2020, primarily due to capital expenditures including personnel-
related costs associated with development of internal-use software of $81.7 million and acquisition of IP of $26.0 million to complement and support our product
development and enhancement initiatives.

Net cash used in investing activities for the year ended December 31, 2020 decreased by $189.1 million as compared to the year ended December 31,
2019,  primarily  due  to  $135.6  million  used  in  2019  to  acquire  our  long-term  investments  and  lower  cash  used  in  2020  for  business  combinations  and  asset
acquisitions  of $91.0 million,  partially  offset  by  higher  capital  expenditures  and  internal  use  software  investment  of  $37.4 million  to  support  the  growth in  our
business.

Net Cash Provided by Financing Activities

Our primary financing activities have consisted of raising proceeds through the issuance of our 2025 Notes and 2026 Notes in the first and third quarters

of 2020, respectively, and stock under our stock plans, offset by partial repurchase and conversion of our 2023 Notes.

Net cash provided by financing activities was approximately $437.6 million for the year ended December 31, 2020, primarily due to $1.6 billion proceeds
from the issuance of our 2025 Notes and 2026 Notes, net of issuance costs, partially offset by $1.1 billion paid for the partial repurchase and conversions of our
2023 Notes and $102.7 million payments for capped calls transactions and costs. We also had proceeds from issuance of stock in connection with our stock plans
of $41.2 million, which was offset with payments for taxes paid in connection with our stock plans of $36.7 million.

Net cash provided by financing activities for the year ended December 31, 2020, increased by $428.5 million as compared to the year ended December 31,
2019, primarily proceeds from the 2025 Notes and the 2026 Notes issued in 2020, partially offset by the partial repurchases and conversions of the 2023 Notes.
Refer to Note 6, Convertible Senior Notes, of the notes to the consolidated financial statements included in Part II, Item 8, “Consolidated Financial Statements and
Supplementary Data” of this Annual Report on Form 10-K for additional information.

Non-GAAP Free Cash Flow

To supplement our statements of cash flows presented on a GAAP basis, we use non-GAAP measures of cash flows to analyze cash flow generated from
our operations. We define free cash flow, a non-GAAP financial measure, as GAAP net cash provided by (used in) operating activities plus cash paid for strategic
partnerships and repayments of convertible senior notes attributable to debt discount, reduced by purchases of property and equipment and capitalized internal-use
software. We believe information regarding free cash flow provides useful information to management and investors in understanding the strength of liquidity and
available cash. A limitation of the use of free cash flow is that it does not represent the total increase or decrease in our cash balance for the period. Free cash flow
should  not  be  considered  in  isolation  or  as  an  alternative  to  cash  flows  from  operations,  and  should  be  considered  alongside  our  other  GAAP-based  financial
liquidity performance measures, such as net cash used in operating activities and our other GAAP financial results.

The following table presents a reconciliation of free cash flow to net cash provided by (used in) operating activities, the most directly comparable GAAP

measure, for each of the periods presented (in thousands):

Net cash (used in) provided by operating activities
Strategic partnerships
Repayment of convertible senior notes attributable to debt discount

We have generally signed new customers contracts with varying length, from month-to-month to multi-year terms for our subscription services. At any
point in the contract term, there can be amounts allocated to services that we have not yet contractually performed, which constitute a backlog. Until we meet our
performance obligations, we do not recognize them as revenues in our consolidated financial statements. Given the variability in our contract length, we believe
that backlog is not a reliable indicator of future revenues and we do not utilize backlog as a key management metric internally.

Deferred Revenue

Deferred revenue primarily consists of the unearned portion of monthly or annual invoiced fees for our subscriptions, which we recognize as revenue in
accordance with our revenue recognition policy. For customers with multi-year contracts, we generally invoice for only one monthly or annual subscription period
in advance. Therefore, our deferred revenue balance does not capture the full contract value of multi-year contracts. Accordingly, we believe that deferred revenue
is not a reliable indicator of future revenues and we do not utilize deferred revenue as a key management metric internally.

Operating lease obligations includes operating leases of $1.1 million that have not yet commenced as of December 31, 2020.

Purchase obligations represent an estimate of open purchase orders and contractual obligations in the normal course of business for which we have not
received the goods or services as of December 31, 2020. Although open purchase orders are considered enforceable and legally binding, except for our purchase
orders with our inventory suppliers, the terms generally allow us the option to cancel, reschedule, and adjust our requirements based on our business needs prior to
the delivery of goods or performance of services. Our purchase orders with our inventory suppliers are non-cancellable. In addition, we have other obligations for
goods and services that we enter into in the normal course of business. These obligations, however, are either not enforceable or legally binding, or are subject to
change based on our business decisions. The aggregate of these items represents our estimate of purchase obligations.

Indemnification Obligations

Certain of our agreements with sales agents, resellers and customers include provisions for indemnification against liabilities if our products infringe a
third-party’s intellectual property rights. To date, we have not incurred any material costs as a result of such indemnification provisions and have not accrued any
liabilities related to such obligations in the consolidated financial statements as of December 31, 2020.

Contingencies

We are and may be in the future subject to certain legal proceedings and from time to time may be involved in a variety of claims, lawsuits, investigations,
and  proceedings  relating  to  contractual  disputes,  intellectual  property  rights,  employment  matters,  regulatory  compliance  matters,  and  other  matters  relating  to
various claims that arise in the normal course of business. We record a provision for a liability when we believe that it is both probable that a liability has been
incurred, and the amount can be reasonably estimated. Significant judgment is required to determine both probability and the estimated amount of loss. Such legal
proceedings  are  inherently  unpredictable  and  subject  to  significant  uncertainties,  some  of  which  are  beyond  our  control.  Should  any  of  these  estimates  and
assumptions change or prove to be incorrect, it could have a significant impact on our results of operations, financial position, and cash flows.

Refer to Note 8 – Commitment and Contingencies of the notes to the consolidated financial statements included in Part II, Item 8, “Consolidated Financial

Statements and Supplementary Data” of this Annual Report on Form 10-K for additional information.

Off-Balance Sheet Arrangements

Through December 31, 2020, we did not have any relationships with unconsolidated organizations or financial partnerships, such as structured finance or
special purpose entities that would have been established for the purpose of facilitating  off-balance sheet arrangements  or other contractually narrow or limited
purposes.

Critical Accounting Policies and Estimates

We prepare our consolidated financial statements in accordance with U.S. GAAP. In many cases, the accounting treatment of a particular transaction is
specifically dictated by U.S. GAAP and does not require management’s judgment in its application. In other cases, management’s judgment is required in selecting
among available alternative accounting standards

58

Table of Contents

that provide for different accounting treatment for similar transactions. The preparation of consolidated financial statements also requires us to make estimates and
assumptions  that  affect  the  amounts  we  report  as  assets,  liabilities,  revenues,  costs,  and  expenses,  and  affect  the  related  disclosures.  We  base  our  estimates  on
historical  experience  and  other  assumptions  that  we  believe  are  reasonable  under  the  circumstances.  In  many  instances,  we  could  reasonably  use  different
accounting  estimates,  and  in  some  instances  changes  in  the  accounting  estimates  are  reasonably  likely  to  occur  from  period  to  period.  Accordingly,  our  actual
results could differ significantly from the estimates made by our management. To the extent that there are differences between our estimates and actual results, our
future financial statement presentation, financial condition, results of operations, and cash flows will be affected. A summary of our significant accounting policies
is included in Note 1 of the notes to the consolidated financial statements included in Part II, Item 8, which is incorporated herein by reference. We believe that the
accounting  policies  discussed  below  are  critical  to  understanding  our  historical  and  future  performance,  as  these  policies  relate  to  the  more  significant  areas
involving management’s judgments and estimates.

Revenue Recognition

We derive our revenues from subscriptions, sale of products, and professional services. Subscriptions revenue is generally recognized over the period of
the subscription contract. Subscription contracts generally allow the customers to terminate their services at any time during the first 30 days of the subscription
period and are charged for the term of usage. Upon cancellation during the termination period, customers receive a pro-rata refund for any amounts paid. After the
end of the termination  period,  the contract  is non-cancellable  and the customer  is obligated  to pay for the remaining  term of the contract.  For sale of products,
revenue is recognized when control is transferred. For professional services, revenue is recognized as services are rendered.

Recent Accounting Pronouncements

For a summary of recent accounting pronouncements and the anticipated effects on our consolidated financial statements, see Note 1 to the consolidated
financial  statements  included  in  Part  II,  Item  8,  “Consolidated  Financial  Statements  and  Supplementary  Data”  of  this  Annual  Report  on  Form  10-K,  which  is
incorporated herein by reference.

ITEM 7A.    Quantitative and Qualitative Disclosures about Market Risk

We are exposed to market risk in the ordinary course of our business. Market risk represents the risk of loss that may impact our financial position due to
adverse changes in financial market prices and rates. Our market risk exposure is primarily a result of fluctuations in foreign currency exchange rates and interest
rates. We do not hold or issue financial instruments for trading purposes.

Foreign Currency Risk

The  majority  of  our  sales  and  contracts  are  denominated  in  U.S.  dollars,  and  therefore  our  net  revenue  is  not  currently  subject  to  significant  foreign
currency  risk.  As  part  of  our  international  operations,  we  charge  customers  in  British  Pounds,  European  Union  (“EU”)  Euro,  Canadian  Dollars  and  Australian
Dollars, among others. Fluctuations in foreign currency exchange rates and volatility in the market, including those resulting from the COVID-19 pandemic, will
cause variability in our revenue. However, this impact has not been significant during 2020. Our operating expenses are generally denominated in the currencies of
the  countries  in  which  our  operations  are  located,  which  are  primarily  in  the  U.S.,  and  to  a  lesser  extent  in  Canada,  Europe,  and  Asia-Pacific.  The  functional
currency of our foreign subsidiaries is generally the local currency. Our consolidated results of operations and cash flows are, therefore, subject to fluctuations due
to changes in foreign currency exchange rates and may be adversely affected in the future due to changes in foreign currency exchange rates. To date, we have not
entered into any hedging arrangements with respect to foreign currency risk. During fiscal 2020, a hypothetical 10% change in foreign currency exchange rates
applicable to our business would not have had a material impact on our consolidated financial statements. As our international operations continue to expand, risks
associated with fluctuating foreign currency rates may increase. We will continue to reassess our approach to managing these risks.

Interest Rate Risk

As of  December  31, 2020,  we had cash  and cash equivalents  of $639.9 million.  We invest  our  cash and cash  equivalents  in short-term  money market
funds. We have experienced a decline in the interest rates associated with money market funds over the last several quarters. Declines in interest rates would reduce
future  interest  income.  During  fiscal  year  2020,  a  hypothetical  10%  increase  or  decrease  in  overall  interest  rates  would  not  have  had  a  material  impact  on  our
interest income. The carrying amount of our cash equivalents reasonably approximates fair values. Due to the short-term nature of our money-market funds, we
believe that exposure to changes in interest rates will not have a material impact on the fair value of our cash equivalents. Interest income may further reduce in the
future due to interest rate volatility in the current macroeconomic environment.

As  of  December  31,  2020,  we  had  $71.2  million,  $825.0  million,  $510.3  million  outstanding  from  the  2023  Notes,  2025  Notes,  and  2026  Notes
(collectively the "Notes"), respectively. We carry the Notes at face value less unamortized discount on our balance sheet, and we present the fair value for required
disclosure purposes only. The Notes have a zero percent fixed annual interest rate and, therefore, we have no economic exposure to changes in interest rates. The
fair value of the Notes is exposed to interest rate risk. Generally, the fair value of our fixed interest rate Notes will increase as interest rates decline and decrease as
interest rates increase. In addition, the fair values of the Notes are affected by our stock price. The fair value of the Notes will generally increase as our common
stock price increases and will generally decrease as our common stock price decrease in value.

Market Risk

As of December 31, 2020, we had long term investments in convertible and redeemable preferred stock of $213.2 million. These equity investments are
subject to market related risks that could decrease or increase the fair value of our holdings. These equity investments are adjusted to fair value based on market
inputs  at  the  balance  sheet  date,  which  are  subject  to  market-related  risks  that  could  decrease  or  increase  the  fair  value  of  our  holdings,  including  the  potential
impacts  from  COVID-19.  A  fluctuation  in  the  investee's  stock  price,  volatility  or  a  combination  of  both  could  have  an  adverse  impact  on  the  fair  value  of  our
investment. A hypothetical adverse stock price or volatility change of 10% could have resulted in a potential decrease of up to $16.8 million in the fair-value of our
investment as of December 31, 2020.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Stockholders and Board of Directors

RingCentral, Inc.:

Opinions on the Consolidated Financial Statements and Internal Control Over Financial Reporting

We  have  audited  the  accompanying  consolidated  balance  sheets  of  RingCentral,  Inc.  and  subsidiaries  (the  Company)  as  of  December  31,  2020  and  2019,  the
related  consolidated  statements  of  operations,  comprehensive  loss,  stockholders’  equity,  and  cash  flows  for  each  of  the  years  in  the  three-year  period  ended
December 31, 2020, and the related notes (collectively, the consolidated financial statements). We also have audited the Company’s internal control over financial
reporting  as  of  December  31,  2020,  based  on  criteria  established  in  Internal  Control  –  Integrated  Framework  (2013) issued  by  the  Committee  of  Sponsoring
Organizations of the Treadway Commission.

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,  2020  and  2019,  and  the  results  of  its  operations  and  its  cash  flows  for  each  of  the  years  in  the  three-year  period  ended  December  31,  2020,  in
conformity with U.S. generally accepted accounting principles. Also in our opinion, the Company maintained, in all material respects, effective internal control
over financial  reporting as of December 31, 2020 based on criteria  established  in Internal Control – Integrated Framework (2013) issued by the Committee of
Sponsoring Organizations of the Treadway Commission.

Change in Accounting Principle

As discussed in Note 1 to the consolidated financial statements, the Company changed its method of accounting for leases as of January 1, 2019 due to the adoption
of Financial Accounting Standards Board's Accounting Standards Codification (ASC) Topic 842, Leases.

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 the accompanying Management’s Annual Report on Internal Controls
Over Financial Reporting appearing in Item 9A of this Annual Report on Form 10-K. Our responsibility is to express an opinion on the Company’s consolidated
financial statements and an opinion 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  in  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  (1)  pertain  to  the  maintenance  of  records  that,  in  reasonable  detail,  accurately  and  fairly  reflect  the
transactions and dispositions of the assets of the company; (2) 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

62

Table of Contents

expenditures  of  the  company  are  being  made  only  in  accordance  with  authorizations  of  management  and  directors  of  the  company;  and  (3)  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.

Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or
required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the consolidated financial statements and (2)
involved our especially challenging, subjective, or complex judgment. The communication of a critical audit matter does not alter in any way our opinion on the
consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical
audit matter or on the accounts or disclosures to which it relates.

Evaluation of the Sufficiency of Audit Evidence Over Subscriptions Revenue

As  discussed  in  Note  1  to  the  consolidated  financial  statements,  and  disclosed  in  the  consolidated  statements  of  operations,  the  Company  recorded
$1,183.7 million of total revenues for the year ended December 31, 2020, of which $1,086.3 million related to subscriptions. There are high volumes of
subscription transactions processed across multiple information technology (IT) systems.

We  identified  the  evaluation  of  the  sufficiency  of  audit  evidence  over  subscriptions  revenue  as  a  critical  audit  matter.  This  matter  required  especially
subjective auditor judgment because of the number of IT applications involved in the subscriptions revenue recognition process. This matter also included
determining  the  nature  and  extent  of  audit  evidence  obtained  over  subscriptions  revenue,  and  the  need  to  involve  IT  professionals  to  assist  with  the
performance of certain procedures.

The  following  are  the  primary  procedures  we  performed  to  address  this  critical  audit  matter.  We  evaluated  the  design  and  tested  the  operating
effectiveness  of  certain  internal  controls  over  the  Company's  subscriptions  revenue  process,  including  associated  IT  controls.  We  applied  auditor
judgment to determine the nature and extent of procedures to be performed over subscriptions revenue, including the determination of the IT applications
subject to testing. We assessed the recorded subscriptions revenue by selecting transactions and comparing the amounts recognized for consistency with
underlying documentation, including contracts with customers. We also involved IT professionals with specialized skills and knowledge, who assisted in
testing  certain  IT  applications  that  are  used  by  the  Company  in  its  subscriptions  revenue  recognition  process.  We  evaluated  the  sufficiency  of  audit
evidence obtained by assessing the results of procedures performed, including the appropriateness of such evidence.

We have served as the Company’s auditor since 2010.

RINGCENTRAL, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note 1. Description of Business and Summary of Significant Accounting Policies

Description of Business

RingCentral,  Inc.  (the  “Company”)  is  a  provider  of  software-as-a-service  (“SaaS”)  solutions  that  enables  businesses  to  communicate,  collaborate  and

connect. The Company was incorporated in California in 1999 and was reincorporated in Delaware on September 26, 2013.

Principles of Consolidation

The accompanying consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States
of America (“U.S. GAAP”) and include the consolidated accounts of the Company and its wholly-owned subsidiaries. All intercompany accounts and transactions
have been eliminated in consolidation.

Use of Estimates

The preparation of consolidated financial statements in conformity with U.S. 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 consolidated financial statements, and the reported
amounts  of  revenues  and  expenses  during  the  reporting  period.  The  significant  estimates  made  by  management  affect  revenues,  the  allowance  for  doubtful
accounts, valuation of long-term investments, deferred and prepaid sales commission costs, goodwill, useful lives of intangible assets, share-based compensation,
capitalization of internally developed software, liability and equity allocation of convertible senior notes, return reserves, provision for income taxes, uncertain tax
positions,  loss  contingencies,  sales  tax  liabilities,  and  accrued  liabilities.  Management  periodically  evaluates  these  estimates  and  will  make  adjustments
prospectively based upon the results of such periodic evaluations. Actual results m differ from these estimates.

In  March  2020,  the  World  Health  Organization  declared  the  outbreak  of  the  novel  strain  of  coronavirus  (“COVID-19”)  as  a  global  pandemic  with
widespread and detrimental effect on the global economy. The extent of the impact of COVID-19 on the Company's operational and financial performance will
depend on certain developments, including the duration and spread of the outbreak, impact on the Company's customers and sales cycles, and its employees, all of
which  are  uncertain  and  cannot  be  predicted.  As  of  the  date  of  issuance  of  these  financial  statements,  the  Company  is  not  aware  of  any  specific  event  or
circumstance that would require updating significant estimates or judgments or revising the carrying value of the Company's assets or liabilities as presented in the
consolidated financial statements. These estimates may change as new events occur and additional information is obtained. Actual results could differ materially
from these estimates.

Foreign Currency

The functional currency of the Company’s foreign subsidiaries is generally the local currency. Adjustments resulting from translating foreign functional
currency financial statements into U.S. dollars are recorded as part of a separate component of stockholders’ equity and reported in the Consolidated Statements of
Comprehensive  Loss.  Foreign  currency  transaction  gains  and  losses  are  included  in  net  loss  for  the  period.  All  assets  and  liabilities  denominated  in  a  foreign
currency are translated into U.S. dollars at the exchange rate on the balance sheet date. Revenues and expenses are translated at the average exchange rate during
the period. Equity transactions are translated using historical exchange rates.

Cash and Cash Equivalents

The Company considers all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents. Cash and cash

equivalents are stated at fair value.

Allowance for Doubtful Accounts

For  the  years  ended  December  31,  2020  and  2019,  a  portion  of  revenues  were  realized  from  credit  card  transactions  while  the  remaining  revenues
generated  accounts  receivable.  The  Company  determines  provisions  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 delinquent accounts.

Long-term investments consist of convertible and redeemable preferred securities in which the Company does not have a controlling interest or significant
influence. These investments are recorded at fair value using both observable and unobservable inputs and the valuation requires judgment. These investments are
reported  at  fair  value  in  long-term  investments  in  the  Consolidated  Balance  Sheets.  All  gains  and  losses  on  these  investments,  realized  and  unrealized,  are
recognized in other income (expense), net in the Consolidated Statements of Operations.

Internal-Use Software Development Costs

The Company  capitalizes  qualifying  internal-use  software  development  costs that  are  incurred  during the application  development  stage,  provided  that
management with the relevant authority authorizes and commits to the funding of the project, it is probable the project will be completed, and the software will be
used  to  perform  the  function  intended.  Costs  related  to  preliminary  project  activities  and  post  implementation  activities  are  expensed  as  incurred.  Capitalized
internal-use software development costs are included in property and equipment and are amortized on a straight-line basis over their estimated useful lives.

For the years ended December 31, 2020 and 2019, the Company capitalized $41.9 million and $18.5 million, net of impairment, of internal-use software
development costs, respectively. The carrying value of internal-use software development costs was $66.4 million and $35.6 million at December 31, 2020 and
2019, respectively.

Property and Equipment, net

Property and equipment, net is stated at cost, less accumulated depreciation and amortization. Depreciation and amortization is calculated on a straight-

line basis over the estimated useful lives of those assets as follows:

Computer hardware and software
Internal-use software development costs
Furniture and fixtures
Leasehold improvements

3 to 5 years
3 to 5 years
1 to 5 years
Shorter of the estimated lease term or useful life

The Company evaluates  the recoverability  of property  and equipment  and intangible  assets  for  possible impairment  whenever  events  or circumstances
indicate that the carrying amount of such assets or asset groups may not be recoverable. Recoverability of these assets or asset groups is measured by comparing
the carrying amounts of such assets or asset groups to the future undiscounted cash flows that such assets or asset groups are expected to generate. If this evaluation
indicates that the carrying amount of the assets or asset groups is not recoverable, the carrying amount of such assets or asset groups is reduced to its estimated fair
value.

Maintenance and repairs are charged to expense as incurred.

Leases

The Company determines if a contract is a lease or contains a lease at the inception of the contract and reassesses that conclusion if the contract is modified.
All  leases  are  assessed  for  classification  as  an  operating  lease  or  a  finance  lease.  Operating  lease  right-of-use  (“ROU”)  assets  are  presented  separately  on  the
Company's Consolidated Balance Sheets. Operating lease liabilities are separated into a current portion, included within accrued liabilities on the Company's

70

Table of Contents

Consolidated Balance Sheets, and a non-current portion included within operating lease liabilities on the Company's Consolidated Balance Sheets. The Company
does not have significant finance lease ROU assets or liabilities. ROU assets represent the Company's right to use an underlying asset for the lease term and lease
liabilities represent its obligation to make lease payments arising from the lease. The Company does not obtain and control its right to use the identified asset until
the lease commencement date.

The Company’s lease liabilities are recognized at the applicable lease commencement date based on the present value of the lease payments required to be
paid over the lease term. Because the rate implicit in the lease is not readily determinable, the Company generally uses an incremental borrowing rate to discount
the  lease  payments  to  present  value.  The  estimated  incremental  borrowing  rate  is  derived  from  information  available  at  the  lease  commencement  date.  The
Company  factors  in  publicly  available  data  for  instruments  with  similar  characteristics  when  calculating  its  incremental  borrowing  rates.  The  Company's  ROU
assets are also recognized at the applicable lease commencement date. The ROU asset equals the carrying amount of the related lease liability, adjusted for any
lease payments made prior to lease commencement and lease incentives provided by the lessor. Variable lease payments are expensed as incurred and do not factor
into the measurement of the applicable ROU asset or lease liability.

The term  of the Company's leases equal the non-cancellable  period of the lease,  including any rent-free  periods provided by the lessor, and also include
options to renew or extend the lease (including by not terminating the lease) that the Company is reasonably certain to exercise. The Company establishes the term
of  each  lease  at  lease  commencement  and  reassesses  that  term  in  subsequent  periods  when  one  of  the  triggering  events  outlined  in  Topic  842,  Leases, occurs.
Operating lease cost for lease payments is recognized on a straight-line basis over the lease term.

The Company's lease contracts often include lease and non-lease components. For facility leases, the Company has elected the practical expedient offered by
the standard to not separate lease from non-lease components and accounts for them as a single lease component. For the Company's other contracts that include
leases, the Company accounts for the lease and non-lease components separately.

The Company has elected, for all classes of underlying assets, not to recognize ROU assets and lease liabilities for leases with a term of twelve months or
less.  Lease  cost  for  short-term  leases  is  recognized  on  a  straight-line  basis  over  the  lease  term.  Additionally,  for  certain  facility  leases,  the  Company  applies  a
portfolio approach, whereby it effectively  accounts for the operating lease ROU assets and liabilities for multiple leases as a single unit of account because the
accounting effect of doing so is not material.

On  January  1,  2019,  the  Company  adopted  Topic  842  using  a  modified  retrospective  transition  approach.  As  a  result,  the  Company  was  not  required  to
adjust  its  comparative  periods'  financial  information  for  effects  of  the  standard  or  make  the  new  required  lease  disclosures  for  the  periods  before  the  date  of
adoption. The adoption of the standard did not have a material impact on the Company's consolidated statement of Operations or Cash Flows. The impact on the
Company's Consolidated Balance Sheet as of January 1, 2019 was the recognition of ROU assets and lease liabilities for operating leases in the amount of $33.5
million.

Goodwill and Intangible Assets

Goodwill is tested for impairment at the reporting unit level at a minimum on an annual basis or more frequently when an event occurs or circumstances
change that indicate that the carrying value may not be recoverable. Goodwill is considered impaired if the carrying value of the reporting unit exceeds its fair
value. The Company conducted its annual impairment test of goodwill in the fourth quarter of 2020 and 2019 and determined that no adjustment to the carrying
value of goodwill was required.

Intangible  assets  consist  of  purchased  customer  relationships  and  developed  technology.  Intangible  assets  are  amortized  over  the  period  of  estimated

benefit using the straight-line method and estimated useful lives ranging from two to five years. No residual value is estimated for intangible assets.

Concentrations

Financial instruments that subject the Company to concentrations of credit risk consist primarily of cash and cash equivalents and accounts receivable.
Although the Company deposits its cash with multiple financial institutions, its deposits, at times, may exceed federally insured limits. The Company’s accounts
receivable are primarily derived from sales by resellers and to larger direct customers. The Company maintains an allowance for doubtful accounts for estimated
potential credit losses.

71

Table of Contents

As  of  December  31,  2020,  2019  and  2018,  and  for  the  years  then  ended,  none  of  the  Company’s  customers  accounted  for  more  than  10%  of  total  accounts
receivable, total revenues, or subscription revenues.

During the years ended December 31, 2020, 2019 and 2018, the Company contracted a significant portion of its software development efforts from third-
party  vendors  located  in  Russia  and  Ukraine.  A  cessation  of  services  provided  by  these  vendors  could  result  in  a  disruption  to  the  Company’s  research  and
development efforts.

Long-lived  assets  by  geographic  location  is  based  on  the  location  of  the  legal  entity  that  owns  the  asset.  As  of  December  31,  2020  and  2019,
approximately 90% and 89% of the Company’s consolidated long-lived assets, respectively, were located in the U.S. No other single country outside of the U.S.
represented more than 10% of the Company’s consolidated long-lived assets as of December 31, 2020 and 2019.

Revenue Recognition

The  Company  derives  its  revenues  primarily  from  subscriptions,  sale  of  products,  and  professional  services.  Revenues  are  recognized  when control  of

these services is transferred to the customers, in an amount that reflects the consideration the Company expects to be entitled to in exchange for those services.

The Company determines revenue recognition through the following steps:

•

•

•

•

•

identification of the contract, or contracts, with a customer;

identification of the performance obligations in the contract;

determination of the transaction price;

allocation of the transaction price to the performance obligations in the contract; and

recognition of revenue when, or as, the Company satisfies a performance obligation.

The Company recognizes revenues as follows:

Subscriptions revenue

Subscriptions revenue is generated from fees that provide customers access to one or more of the Company’s software applications and related services.
These arrangements have contractual terms typically ranging from one month to five years and include recurring fixed plan subscription fees and variable usage-
based fees for usage in excess of plan limits.

Arrangements with customers do not provide the customer with the right to take possession of the Company’s software at any time. Instead, customers are
granted continuous access to the services over the contractual period. The Company transfers control evenly over the contractual period by providing stand-ready
service. Accordingly, the fixed consideration related to subscription is recognized over time on a straight-line basis over the contract term beginning on the date the
Company’s service is made available to the customer. The Company may offer its customer services for no consideration during the initial months. Such discounts
are recognized ratably over the term of the contract.

Fees  for  additional  minutes  of  usage  in  excess  of  plan  limits  are  deemed  to  be  variable  consideration  that  meet  the  allocation  exception  for  variable

consideration as they are specific to the month that the usage occurs.

The Company’s subscription contracts typically allow the customers to terminate their services within the first 30 or 60 days and receive a refund for any
amounts paid. After the end of the termination period, the contract is non-cancellable and the customer is obligated to pay for the remaining term of the contract.
Accordingly, the Company considers the non-cancellable term of the contract to begin after the expiration of the termination period.

The Company records reductions to revenue for estimated sales returns and customer credits at the time the related revenue is recognized. Sales returns
and customer credits are estimated based on the Company’s historical experience, current trends and the Company’s expectations regarding future experience. The
Company monitors the accuracy of its sales reserve estimates by reviewing actual returns and credits and adjusts them for its future expectations to determine the
adequacy of its current and future reserve needs. If actual future returns and credits differ from past experience, additional reserves may be required.

Other revenue

Other revenue includes revenue generated from sale of pre-configured phones, professional implementation services, and phone rentals.

Phone revenue  is  recognized  upon transfer  of  control  to  the  customer  which  is  generally  upon shipment  from  the  Company’s  or  its  designated  agents'

warehouse. The amount of revenue recognized for products is adjusted for expected returns, which are estimated based on historical data.

The Company offers professional services to support implementation and deployment of its subscription services. Professional services do not result in
significant  customization  of the product  and are  generally  short-term  in duration.  The majority  of the Company’s professional  services  contracts  are  on a fixed
price basis and revenue is recognized when services are delivered.

Principal vs. Agent

A portion of the Company’s subscriptions and product revenues are generated through sales by resellers, strategic partners, and carrier partners. When the
Company controls the performance of contractual obligations to the customer, it records these revenues at the gross amount paid by the customer with amounts
retained  by  the  resellers  recognized  as  sales  and  marketing  expenses.  The  Company  assesses  control  of  goods  or  services  when  it  is  primarily  responsible  for
fulfilling the promise to provide the good or service, has inventory risk and has discretion in establishing the price.

Deferred and prepaid sales commission costs

The Company capitalizes sales commission expenses and associated payroll taxes paid to internal sales personnel and resellers, who sell the Company’s
offerings. The resellers are selling agents for the Company and earn sales commissions which are directly tied to the value of the contracts that the Company enters
with the end-user customers. These sales commissions are incremental costs the Company incurs to obtain contracts with its end-user customers. The Company
pays sales commissions on initial contracts and contracts for increased purchases with existing customers (expansion contracts). The Company does not pay sales
commissions for contract renewals.

These sales commission costs are deferred and then amortized over the expected period of benefit, which is estimated to be five years. The Company has
determined the period of benefit taking into consideration the expected subscription term and expected renewal periods of its customer contracts, the duration of its
relationships with its customers considering historical and expected customer retention, technology and other factors. Amortization expense is included in sales and
marketing expenses in the accompanying Consolidated Statements of Operations.

Cost of Revenues

Cost  of  subscriptions  revenue  primarily  consists  of  costs  of  network  capacity  purchased  from  third-party  telecommunications  providers,  network
operations, costs to build out and maintain data centers, including co-location fees for the right to place the Company’s servers in data centers owned by third-
parties, depreciation of the servers and equipment, along with related utilities and maintenance costs, personnel costs associated with customer care and support of
the  functionality  of  the  Company’s  platform  and  data  center  operations,  including  share-based  compensation  expenses,  and  allocated  costs  of  facilities  and
information technology. Cost of subscriptions revenue is expensed as incurred.

Cost of other revenue is comprised primarily of the cost associated with purchased phones, shipping costs, costs of professional services, and allocated
costs of facilities and information technology related to the procurement, management and shipment of phones. Cost of other revenue is expensed in the period
product is delivered to the customer.

Share-Based Compensation

Share-based compensation expense resulting from options, restricted stock units (“RSUs”), performance-based awards, and employee stock purchase plan
(“ESPP”)  rights  granted  is  measured  as  the  grant  date  fair  value  of  the  award  and  is  generally  recognized  using  the  straight-line  attribution  method  over  the
requisite service period of the award, which is generally the vesting period. The Company estimates the fair value of stock options, ESPP rights, and performance-
based awards using the Black-Scholes-Merton  option-pricing model. The Company estimates the fair value of RSUs as the closing market value of its Class A
Common Stock on the grant date. For awards with performance-based  and service-based  conditions, compensation  cost is recognized  over the requisite  service
period if it is probable that the performance condition will be satisfied. The expense for

73

Table of Contents

performance-based awards is evaluated each quarter based on the achievement of the performance conditions. The effect of a change in the estimated number of
performance-based  awards  expected  to  be  earned  is  recognized  in  the  period  those  estimates  are  revised.  Compensation  expense  is  recognized  net  of  estimated
forfeiture activity, which is based on historical forfeiture rates.

Research and Development

Research  and  development  expenses  consist  primarily  of  third-party  contractor  costs,  personnel  costs,  technology  license  expenses,  and  depreciation

associated with research and development equipment. Research and development costs are expensed as incurred.

Advertising Costs

Advertising  costs,  which  include  various  forms  of  e-commerce  such  as  search  engine  marketing,  search  engine  optimization  and  online  display
advertising, as well as more traditional forms of media advertising such as radio and billboards, are expensed as incurred and were $76.6 million, $59.9 million,
and $58.3 million for the years ended December 31, 2020, 2019 and 2018, respectively.

Convertible Debt

The Company bifurcates the debt and equity (the contingently convertible feature) components of its convertible debt instruments in a manner that reflects
its nonconvertible debt borrowing rate at the time of issuance. The equity components of the convertible debt instruments are recorded within stockholders’ equity
with an allocated issuance discount. The debt issuance discount is amortized to interest expense in the Consolidated Statements of Operations using the effective
interest method over the expected term of the convertible debt.

Income Taxes

The Company accounts for income taxes using the asset and liability method. Deferred tax assets and liabilities are recognized for the estimated future tax
consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis. Deferred
tax assets and liabilities are measured using enacted tax rates in effect for the year in which those temporary differences are expected to be recovered or settled. The
effect on deferred tax assets and liabilities of a change in tax rates is recognized in operations in the period that includes the enactment date. The Company records
a valuation allowance to reduce its deferred tax assets to the amount of future tax benefit that is more likely than not to be realized. As of December 31, 2020,
except for deferred tax assets associated with its subsidiary in China, the Company recorded a full valuation allowance against all other net deferred tax assets due
to its history of operating losses. The Company classifies interest and penalties on unrecognized tax benefits as income tax expense.

Segment Information

The Company has determined the chief executive officer is the chief operating decision maker. The Company’s chief executive officer reviews financial
information  presented  on  a  consolidated  basis  for  purposes  of  assessing  performance  and  making  decisions  on  how  to  allocate  resources.  Accordingly,  the
Company has determined that it operates in a single reportable segment.

Indemnification

Certain of the Company’s agreements with resellers and customers include provisions for indemnification against liabilities if its subscriptions infringe
upon a third-party’s intellectual property rights. At least quarterly, the Company assesses the status of any significant matters and its potential financial statement
exposure.  If  the  potential  loss  from  any  claim  or  legal  proceeding  is  considered  probable  and  the  amount  or  the  range  of  loss  can  be  estimated,  the  Company
accrues a liability for the estimated loss. The Company has not incurred any material costs as a result of such indemnification provisions. The Company has not
accrued any material liabilities related to such obligations as of December 31, 2020 and 2019.

Recent Accounting Pronouncements Not Yet Adopted

In December 2019, the Financial Accounting Standard Board ("FASB") issued Accounting Standard Update ("ASU") No. 2019-12, Accounting Standards
Update  (Topic  740):  Simplifying  the  Accounting  for  Income  Taxes.  The  ASU  removed  certain  exceptions  for  recognizing  deferred  taxes  for  investments,
performing intraperiod allocation and calculating income

74

Table of Contents

taxes in interim periods. The ASU added guidance to reduce complexity in certain areas, including recognizing deferred taxes for goodwill and allocating taxes to
members of a consolidated group. The ASU also amended the reporting requirement of taxes not based on income. The ASU is effective for calendar year-end
public  entities  on  January  1,  2021.  Entities  may  early  adopt  the  ASU  in  any  interim  period  for  which  financial  statements  have  not  yet  been  issued  (or  made
available for issuance). The Company has not yet adopted the new guidance. The adoption is not expected to have a material impact on the Company's consolidated
financial statements.

In March 2020, the FASB issued optional guidance for a limited time to ease the potential burden in accounting for or recognizing the effects of reference
rate reform, particularly, the risk of cessation of the London Interbank Offered Rate ("LIBOR") on financial reporting. The guidance provides optional expedients
and  exceptions  for  applying  GAAP  to  contracts,  hedging  relationships,  and  other  transactions  affected  by  reference  rate  reform  if  certain  criteria  are  met.  The
amendments are elective and are effective upon issuance for all entities through December 31, 2022. The Company is currently evaluating the impact of the new
guidance.

In August 2020, the FASB issued ASU No. 2020-06, Accounting for Convertible Instruments and Contracts in an Entity's Own Equity, which simplifies
the accounting for certain convertible instruments, amends the guidance on derivative scope exceptions for contracts in an entity's own equity, and modifies the
guidance on diluted earnings per share calculations as a result of these changes. This new standard is effective for public entities for fiscal years beginning after
December 15, 2021, and interim periods within those fiscal years. The amendment is to be adopted through either a fully retrospective or modified retrospective
method of transition. Early adoption is permitted. The Company is currently evaluating the impact of the new guidance on its consolidated financial statements.

Note 4. Fair Value of Financial Instruments

The  Company  measures  and  reports  certain  cash  equivalents,  including  money  market  funds  and  certificates  of  deposit,  in  addition  to  its  long-term
investments  at  fair  value  in  accordance  with  the  provisions  of  the  authoritative  accounting  guidance  that  addresses  fair  value  measurements.  This  guidance
establishes  a  hierarchy  for  inputs  used  in  measuring  fair  value  that  maximizes  the  use  of  observable  inputs  and  minimizes  the  use  of  unobservable  inputs  by
requiring that the most observable inputs be used when available. 

77

Table of Contents

The hierarchy is broken down into three levels based on the reliability of the inputs as follows:

Level 1:    Observable inputs that reflect unadjusted quoted prices in active markets for identical assets or liabilities.

Level 2:    Other inputs, such as quoted prices for similar assets or liabilities, quoted prices for identical or similar assets or liabilities in inactive markets,

or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the asset or liability.

Level 3:    Unobservable inputs that are supported by little or no market activity and that are based on management’s assumptions, including fair value

measurements determined by using pricing models, discounted cash flow methodologies or similar techniques.

The financial assets carried at fair value were determined using the following inputs (in thousands):

The  Company’s  other  financial  instruments,  including  accounts  receivable,  accounts  payable,  and  other  current  liabilities,  are  carried  at  cost,  which

approximates fair-value due to the relatively short maturity of those instruments.

Convertible Senior Notes    

As of December 31, 2020, the fair value of the 0% convertible senior notes due 2026 (the "2026 Notes") was approximately $763.9 million. The fair value
was determined based on the quoted price for the 2026 Notes in an inactive market on the last trading day of the reporting period and is considered as Level 2 in the
fair value hierarchy.

As of December 31, 2020, the fair value of the 0% convertible senior notes due 2025 (the “2025 Notes”) was approximately $1.3 billion. The fair value
was determined based on the quoted price for the 2025 Notes in an inactive market on the last trading day of the reporting period and is considered as Level 2 in the
fair value hierarchy.

As of December 31, 2020, the fair value of the 0% convertible senior notes due 2023 (the “2023 Notes”) was approximately $381.1 million. The fair value
was determined based on the quoted price for the 2023 Notes in an inactive market on the last trading day of the reporting period and is considered as Level 2 in the
fair value hierarchy.

Long-Term Investments

As of December 31, 2020 and 2019, the fair value of the Company's long-term investments in convertible and redeemable preferred stock was $213.2
million and $132.2 million, respectively. The Company classifies its long-term investments as Level 3 in the fair value hierarchy based on the nature of the fair
value  inputs  and  judgment  involved  in  the  valuation  process.  The  Company  uses  a  lattice  model  to  value  these  investments  and  relies  on  observable  inputs
including share-price, credit spread, and volatility. The model also incorporates judgments relating to the probability of special redemption triggers, the expected
holding period of the investment and interest rates. These investments are reported at fair value in long-term investments in the Consolidated Balance Sheets. The
Company's total net unrealized gain recorded in other income (expense), net, for the years ended December 31, 2020 and 2019 was $77.2 million and $6.6 million,
respectively.  Volatility  in  the  global  economic  climate  and  financial  markets,  including  the  effects  of  COVID-19,  could  result  in  a  significant  change  in  the
underlying share-price of the Company’s investees, resulting in a material change in the value of the long-term investments.

Note 5. Business Combinations, Strategic Partnerships, and Asset Acquisitions

In November 2020, the Company entered into a strategic partnership with Vodafone Group Services Limited (“Vodafone”), a telecommunication provider
in  Europe  and  Africa.  The  parties  intend  to  introduce  a  new  co-branded  cloud-based  service  that  will  be  the  Unified  Communications  as  a  Service  ("UCaaS")
solution for Vodafone and offer Contact Center as a Service (“CCaaS”) to Vodafone’s customers. In July 2020, the Company entered into a strategic partnership
with  Alcatel-Lucent  Enterprise  ("ALE"),  a  provider  of  communications,  networking,  and  cloud  solutions  in  Europe.  The  parties  intend  to  introduce  a  new  co-
branded  solution,  which  will  be  the  UCaaS  solution  marketed  and  sold  by  ALE.  In  addition  to  the  above  transactions,  in  2020,  the  Company  also  entered  into
arrangements with unrelated third parties to acquire intellectual property rights. Under these agreements, the Company paid total upfront consideration of $141.6
million in cash. These consideration represent cost to obtain contracts with customers and were included in deferred and prepaid sales commission costs on the
Company's Consolidated Balance Sheets. The Company also paid $26.6 million to acquire intellectual property rights, which will be amortized over their expected
useful life of approximately two years to four years.

In December 2019, the Company entered into a strategic partnership with Atos SE ("Atos") and its subsidiary, Unify Software and Solutions GmbH &
CO. KG ("Unify"), which, among other things, provided for a one-time upfront consideration towards the acquisition of certain intellectual property rights and a
commercial  arrangement.  Under  the  commercial  agreement  Unify  is  engaged  in  the  marketing  and  sale  of  the  Company's  product,  which  represents  advance
payment  for  cost  to  obtain  contracts  with  customers.  In  October  2019,  the  Company  entered  into  certain  agreements  for  a  strategic  partnership  with  Avaya
Holdings Corp. (“Avaya”) and its subsidiaries, including Avaya Inc. In connection with the strategic partnership, the Company purchased $125.0 million aggregate
principal amount of 3% convertible and redeemable preferred stock, with a conversion price of $16.00 per share, representing an approximately 6% position in
Avaya on an as-converted basis. The Company also paid Avaya $345.0 million in the Company's Class A Common Stock, predominantly for future fees, which
was capitalized and will be amortized over the expected benefit period. The transaction closed on October 31, 2019. The investment in preferred securities in which
the Company does not have a controlling interest or significant influence are measured at fair value with changes recorded through other income (expense) in the
Consolidated Statements of Operations. The advance payment represents prepayment for cost to obtain contracts with customers. The Company also purchased
intellectual property rights, which have been capitalized as an intangible asset and will be amortized over the useful life of three years. In addition to the above
transactions, in 2019, the Company also separately entered into arrangements with unrelated third parties to acquire intellectual property rights.

In connection with the above transactions, in 2019, the Company recorded in aggregate $105.5 million in acquired intangible assets relating to developed
technology on the Consolidated Balance Sheets, which will be amortized over their respective useful life of three to five years. The Company also recorded $371.1
million as deferred and prepaid sales commission costs representing cost to obtain contracts with customers. The prepaid assets will be amortized over their useful
life based on the pattern of benefit since they are considered to be incremental customer acquisition costs. Certain of the strategic agreements entered in 2020 and
2019  may  require  the  parties  to  incur  certain  costs  towards  strategic  efforts.  Such  net  costs  are  recorded  as  cost  of  revenues  and  operating  expenses  in  the
Consolidated Statements of Operations, in the period incurred.

On  January  14,  2019,  the  Company  acquired  the  equity  interests  of  Connect  First,  Inc.  (“Connect  First”),  a  cloud-based  outbound/blended  customer
engagement  platform  for  midsize  and  enterprise  companies.  The  acquisition  complements  the  Company’s  current  Customer  Engagement  portfolio  to  provide
differentiated customer experiences.

       The  total  purchase  price  of  approximately  $36.4  million  consisted  of  cash  of  $29.3  million  and  $7.1  million  held  to  cover  indemnity  claims  made  by  the
Company after the closing date. In connection with the acquisition, the Company granted $4.0 million in restricted stock units, which vest over four years.

    The amortizable intangible assets have a weighted average useful life of three years. The purchase price exceeded the estimated fair value of the tangible and
identifiable intangible assets and liabilities acquired and, as a result of the allocation, the Company recorded goodwill of $24.5 million, which is not deductible for
tax purposes. The goodwill recognized is attributable primarily to contributions of the entity's technology to the overall corporate strategy, enhancements to the
Company's contact center product offerings, and assembled workforce of the acquired business.

Note 6. Convertible Senior Notes

In March 2018, the Company issued $460.0 million aggregate principal amount of 0% convertible senior notes due 2023 in a private placement, including
the  exercise  in  full  of  the  over-allotment  options  of  the  initial  purchasers  (the  "2023  Notes").  The  2023  Notes  will  mature  on  March  15,  2023,  unless  earlier
repurchased  or  redeemed  by  the  Company  or  converted  pursuant  to  their  terms.  The  total  net  proceeds  from  the  debt  offering,  after  deducting  initial  purchase
discounts and debt issuance costs, were approximately $449.5 million.

In March 2020, the Company issued $1.0 billion aggregate principal amount of 0% convertible senior notes due 2025 in a private placement to qualified
institutional  buyers  (the  "2025  Notes").  The  2025  Notes  will  mature  on  March  1,  2025,  unless  earlier  repurchased  or  redeemed  by  the  Company  or  converted
pursuant  to  their  terms.  The  total  net  proceeds  from  the  debt  offering,  after  deducting  initial  purchase  discounts  and  debt  issuance  costs,  were  approximately
$986.5 million.

In  September  2020,  the  Company  issued  $650  million  aggregate  principal  amount  of  0%  convertible  senior  notes  due  2026  in  a  private  placement  to
qualified  institutional  buyers  (the  "2026  Notes").  The  2026  Notes  will  mature  on  March  15,  2026,  unless  earlier  repurchased  or  redeemed  by  the  Company  or
converted  pursuant  to  their  terms.  The  total  net  proceeds  from  the  debt  offering,  after  deducting  initial  purchase  discounts  and  debt  issuance  costs,  were
approximately $640.2 million.

The 2023 Notes, 2025 Notes and 2026 Notes (collectively, the “Notes”) are senior, unsecured obligations of the Company that do not bear regular interest,
and  the  principal  amount  of  the  Notes  do  not  accrete.  The  Notes  may  bear  special  interest  under  specified  circumstances  relating  to  the  Company's  failure  to
comply with its reporting obligations under the indentures governing each of the Notes (collectively, the "Notes Indentures") or if the Notes are not freely tradeable
as required by each respective Notes Indenture.

Partial Repurchase of 2023 Notes

In  March  2020,  the  Company  used  $509.6  million  of  the  net  proceeds  from  the  offering  of  the  2025  Notes  to  repurchase  $172.5  million  aggregate
principal  amount  of  the  2023  Notes  in  cash  through  individual  privately  negotiated  transactions  (the  “First  Partial  Repurchase  of  2023  Notes”).  Of  the  $509.6
million net proceeds, $153.7 million and $355.9 million were allocated to the debt and equity components, respectively. As of the repurchase date, the carrying
value of the 2023 Notes subject to the First Partial Repurchase of 2023 Notes, net of unamortized debt discount and issuance costs, was $146.4 million. The First
Partial Repurchase of 2023 Notes resulted in a $7.3 million loss on early debt extinguishment.

In September 2020, the Company used $452.6 million of the net proceeds from the offering of the 2026 Notes to repurchase $132.6 million aggregate
principal amount of the 2023 Notes in cash through individual privately negotiated transactions (the “Second Partial Repurchase of 2023 Notes”). Of the $452.6
million net proceeds, $121.1 million and $331.5 million were allocated to the debt and equity components, respectively. As of the repurchase date, the carrying
value of the 2023 Notes subject to the Second Partial Repurchase of 2023 Notes, net of unamortized debt discount and issuance costs, was $115.6 million. The
Second Partial Repurchase of 2023 Notes resulted in a $5.5 million loss on early debt extinguishment.

80

Table of Contents

The  allocation  between  the  debt  and  equity  components  utilized  an  effective  interest  rate  to  determine  the  fair  value  of  the  liability  component.  The
interest rate reflected the Company's incremental  borrowing rate, adjusted for the Company's credit standing on nonconvertible debt with similar maturity as of
each repurchase date.

Redemptions of 2023 Notes

During the year ended December 31, 2020, the Company received conversion requests of approximately $109.6 million, of which approximately $74.7
million principal amount were settled during the year. The Company recognized an immaterial loss on these conversions, representing the fair value of the liability
component in excess of the net carrying amount of the converted notes on the respective settlement dates. The amount is included in other income (expense), net in
the Consolidated Statement of Operations.

In relation to the remaining $34.9 million principal amount of unsettled conversion requests, as of December 31, 2020, the Company reclassified the net
carrying  value  of  the  debt  of  $31.1  million  from  long-term  to  short-term  debt  and  a  portion  of  equity  of  approximately  $3.8  million  to  temporary  equity.  The
amount  reclassified  to  temporary  equity  represents  the  difference  between  the  principal  and  net  carrying  amount  of  the  liability  component  of  the  2023  Notes
requested  for  conversion.  These  requests  will  be  settled  during  the  first  quarter  of  fiscal  2021.  In  addition,  from  January  1,  2021  to  the  date  of  this  filing,  the
Company has received additional conversion requests for $4.1 million principal amounts, which are expected to be settled during the quarter ending March 31,
2021.

The conversion rate is subject to adjustment upon the occurrence of certain specified events but will not be adjusted for any accrued and unpaid special
interest.  In addition, upon the occurrence  of a make-whole  fundamental  change  or a redemption  period, each  as defined in the respective  Notes Indentures,  the
Company will, in certain circumstances, increase the conversion rate by a number of additional shares for a holder that elects to convert its Notes in connection
with such make-whole fundamental change or during the relevant redemption period.

The 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 December

15, 2022, December 1, 2024, and December 15, 2025, for the 2023 Notes, 2025 Notes, and 2026 Notes respectively, only under the following circumstances:

(1) during any calendar quarter commencing after June 30, 2018 for the 2023 Notes, June 30, 2020 for the 2025 Notes, and December 31, 2020 for
the 2026 Notes, and only during such calendar quarter, if the last reported sale price of the Class A Common Stock for at least 20 trading days (whether or
not  consecutive)  during  a  period  of  30  consecutive  trading  days  ending  on,  and  including,  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 in which, for each trading day of that period, the trading price
per $1,000 principal amount of each Notes for such trading day was less than 98% of the product of the last reported sale price of the Class A Common
Stock and the conversion rate for the respective Notes on each such trading day;

(3) upon the Company’s notice that it is redeeming any or all of either of the Notes, but only with respect to the Notes called for redemption, at any

time prior to the close of business on the scheduled trading day immediately preceding the redemption date; or

(4) upon the occurrence of specified corporate events.

On or after December 15, 2022 for the 2023 Notes, December 1, 2024 for the 2025 Notes, and December 15, 2025 for the 2026 Notes, until the close of
business on the scheduled trading day immediately preceding the maturity date, holders of the Notes may convert all or a portion of their notes regardless of the
foregoing conditions.

81

Table of Contents

Upon conversion, the Company will pay or deliver, as the case may be, either cash, shares of Class A Common Stock or a combination of cash and shares

of Class A Common Stock, at the Company’s election. It is the Company’s current intent to settle the principal amount of the Notes with cash.

During the three months ended December 31, 2020, the stock price condition allowing holders of the 2023 Notes to convert was met. As a result, holders
have the option to convert their 2023 Notes at any time during the fiscal quarter ending March 31, 2021. During the three months ended December 31, 2020, the
conditions  allowing  holders  of  the  2025  and  2026  Notes  to  convert  were  not  met.  The  Notes  may  be  convertible  thereafter  if  one  or  more  of  the  conversion
conditions specified in the indentures are satisfied during future measurement periods.

The Company may redeem at its option, on or after September 20, 2020 for the 2023 Notes, March 5, 2022 for the 2025 Notes, and March 20, 2023 for
the 2026 Notes, at a redemption price equal to 100% of the principal amount thereof, plus accrued and unpaid special interest if the last reported sale price of the
Company’s  Class  A  Common  Stock  has  been  at  least  130%  of  the  conversion  price  then  in  effect  for  at  least  20  trading  days  (whether  or  not  consecutive),
including  the  trading  day  immediately  preceding  the  date  on  which  the  Company  provides  notice  of  redemption,  during  any  30  consecutive  trading  day  period
ending  on,  and  including,  the  trading  day  immediately  preceding  the  date  on  which  the  Company  provides  written  notice  of  redemption.  No  sinking  fund  is
provided for the Notes.

Upon  the  occurrence  of  a  fundamental  change  (as  defined  in  each  respective  Notes  Indentures)  prior  to  the  maturity  date,  holders  may  require  the
Company to repurchase all or a portion of the 2023 Notes, 2025 Notes or 2026 Notes for cash at a price equal to 100% of the principal amount of the Notes to be
repurchased, plus any accrued and unpaid special interest to, but excluding, the fundamental change repurchase date.

The  2026  Notes  are  senior  unsecured  obligations  and  will  rank  senior  in  right  of  payment  to  any  of  the  Company’s  indebtedness  that  is  expressly
subordinated  in  right  of  payment  to  the  2026  Notes;  equal  in  right  of  payment  with  the  Company’s  existing  and  future  liabilities  that  are  not  so  subordinated,
including the 2023 Notes and the 2025 Notes; effectively junior in right of payment to any of the Company’s secured indebtedness to the extent of the value of the
assets securing such indebtedness; and structurally junior to all indebtedness and other liabilities (including trade payables) of current or future subsidiaries of the
Company.

Accounting for the Notes

In accounting for the issuance of the Notes, the Company separated the respective 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 of the Notes representing the conversion option was determined by deducting the fair value of the liability component from the par
value. 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 (“debt discount”) is amortized to interest expense at an effective interest rate over the contractual terms of the note.

In accounting for the transaction costs related to the Notes, the Company allocated the total amount incurred to the liability and equity components of the
notes  based  on  the  proportion  of  the  proceeds  allocated  to  the  debt  and  equity  components.  Issuance  costs  attributable  to  the  liability  component  recorded  as
additional debt discount were $8.2 million for the 2023 Notes, $10.9 million for the 2025 Notes, and $7.7 million for the 2026 Notes, and will be amortized to
interest expense using the effective interest method over the contractual terms of the 2026 Notes. Issuance costs attributable to the equity component of the Notes
were netted with the equity component in stockholders’ equity.

The initial net carrying amount of the equity component of the Notes were as follows (in thousands):

In connection with the offering of the Notes, the Company entered into privately-negotiated capped call transactions relating to each series of notes with
certain counterparties (collectively the “Capped Calls”). The initial strike price of the Notes corresponds to the initial conversion price of each of the Notes. The
Capped Calls are generally intended to reduce or offset the potential dilution to the Class A Common Stock upon any conversion of the Notes with such reduction
or offset, as the case may be, subject to a cap based on the cap price. The Capped Calls settle in components commencing and expiring on dates specified in the
table  below.  The  Capped  Calls  are  subject  to  either  adjustment  or  termination  upon  the  occurrence  of  specified  extraordinary  events  affecting  the  Company,
including a merger event; a tender offer; and a nationalization, insolvency or delisting involving the Company. In addition, the Capped Calls are subject to certain
specified  additional  disruption  events  that  may  give  rise  to  a  termination  of  the  Capped  Calls,  including  changes  in  law;  insolvency  filings;  and  hedging
disruptions.  The  Capped  Call  transactions  are  recorded  in  stockholders’  equity  and  are  not  accounted  for  as  derivatives.  The  net  cost  incurred  to  purchase  the
Capped Call transactions was recorded as a reduction to additional paid-in-capital on the Company's Consolidated Balance Sheets.

Legal Matters

The  Company  is  subject  to  certain  legal  proceedings  described  below,  and  from  time  to  time  may  be  involved  in  a  variety  of  claims,  lawsuits,
investigations,  and  proceedings  relating  to  contractual  disputes,  intellectual  property  rights,  employment  matters,  regulatory  compliance  matters,  and  other
litigation matters relating to various claims that arise in the normal course of business.

The Company determines whether an estimated loss from a contingency should be accrued by assessing whether a loss is deemed probable and can be
reasonably estimated. The Company assesses its potential liability by analyzing specific litigation and regulatory matters using reasonably available information.
The Company develops its views on estimated losses in consultation with inside and outside counsel, which involves a subjective analysis of potential results and
outcomes, assuming various combinations of appropriate litigation and settlement strategies. Actual claims could settle or be adjudicated against the Company in
the future for materially different amounts than the Company has accrued due to the inherently unpredictable nature of litigation. Legal fees are expensed in the
period in which they are incurred.

TCPA Matter

On November 17, 2017, Joann Hurley (“Hurley”), filed a second amended complaint in an ongoing putative class action lawsuit pending in the United
States District Court for the Southern District of West Virginia, adding the Company as a named defendant and alleging that the Company and other defendants
violated the Telephone Consumer Protection Act (“TCPA”) and regulations promulgated thereunder by allegedly using an automated telephone dialing system to
deliver prerecorded political messages to Hurley, an incumbent running for reelection, and others. Hurley alternatively alleged that the Company was vicariously
liable for the actions of the other co-defendants. Hurley seeks statutory, compensatory, consequential, incidental and punitive damages, costs, and attorneys’ fees in
connection with her claims. The Company was served with the second amended complaint on January 4, 2018. On March 23, 2018, the Company filed a motion to
dismiss the complaint for lack of standing and failure to sufficiently state a claim on which relief may be granted. Hurley filed her opposition brief on April 6,
2018, and the Company filed its reply brief on April 13, 2018. On October 4, 2018, the district court issued its memorandum and opinion order granting in part and
denying in part the Company’s motion to dismiss. The district court dismissed Hurley’s vicarious liability claim but allowed Hurley’s TCPA claim to proceed. The
Company filed its answer and affirmative defenses to the second amended complaint on October 18, 2018. Hurley filed a motion to certify a class on July 9, 2019.
The Company and another defendant filed oppositions to the motion, which were fully briefed and are pending decision by the court. Discovery closed on October
25,  2019.  The  Company  filed  a  motion  for  summary  judgment  on  November  14,  2019.  Hurley  opposed  the  motion,  which  also  has  been  fully  briefed  and  is
pending decision by the court. The parties mediated the case before a private mediator on January 23, 2020, at which time a tentative settlement was achieved. A
fairness hearing on the proposed settlement was held on January 25, 2021, at which time the Court tentatively gave final approval of the settlement. The Court
thereafter entered its final order and judgement approving the settlement on February 9, 2021. Any appeal of the Court's order must be filed by March 12, 2021. If
no appeal is filed, the settlement will become effective as of March 12, 2021. The consolidated financial statements include an immaterial accrual for the estimated
loss that is expected to occur.

Patent Infringement Matter

On April 25, 2017, Uniloc USA, Inc. and Uniloc Luxembourg, S.A. (together, “Uniloc”) filed in the U.S. District Court for the Eastern District of Texas
two actions against the Company alleging infringement of U.S. Patent Nos. 7,804,948; 7,853,000; and 8,571,194 by RingCentral’s Glip unified communications
application.  The  plaintiffs  seek  a  declaration  that  the  Company  has  infringed  the  patents,  damages  according  to  proof,  injunctive  relief,  as  well  as  their  costs,
attorney’s fees, expenses and interest. On October 9, 2017, the Company filed a motion to dismiss or transfer requesting that the case be transferred to the United
States  District  Court  for  the  Northern  District  of  California.  In  response  to  the  motion,  plaintiffs  filed  a  first  amended  complaint  on  October  24,  2017.  The
Company filed a renewed motion to dismiss or transfer on November 15, 2017. Although briefing on that motion has been completed, the motion has not yet been
decided. On February 5, 2018, Uniloc moved to stay the litigation pending the resolution of certain third-party inter partes review proceedings (“IPRs”) before the
United States Patent and Trademark Office. On February 9, 2018, the court stayed the litigation pending resolution of the IPRs without prejudice to or waiver of the
Company’s motion to dismiss or transfer. This litigation is still in its earliest stages. Based on the information known by the Company as of the date of this filing
and the rules and regulations applicable to the preparation of the Company’s consolidated financial statements, it is not possible to provide an estimated amount of
any such loss or range of loss that may occur. The Company intends to vigorously defend against this lawsuit.

CIPA Matter

On June 16, 2020, Plaintiff Meena Reuben (“Reuben”) filed a complaint against the Company for a putative class action lawsuit in California Superior
Court for San Mateo County. The complaint alleges claims on behalf of a class of individuals for whom, while they were in California, the Company allegedly
intercepted  and  recorded  communications  between  individuals  and  the  Company’s  customers  without  the  individual’s  consent,  in  violation  of  the  California
Invasion  of  Privacy  Act  (“CIPA”)  Sections  631  and  632.7.  Reuben  seeks  statutory  damages  of  $5,000  for  each  alleged  violation  of  Sections  631  and  632.7,
injunctive relief, and attorneys’ fees and costs, and other unspecified amount of damages. On July 7, 2020, the Court granted the parties’ stipulation to extend time
for the Company to respond to the Reuben’s complaint. The Company has not responded to the complaint. This litigation is still in its earliest stages. Based on the
information known by the Company as of the date of this filing and the rules and regulations applicable to the preparation of the Company’s consolidated financial

86

Table of Contents

statements, it is not possible to provide an estimated amount of any such loss or range of loss that may occur. The Company intends to vigorously defend against
this lawsuit.

Other matter

On June 14, 2019, the Company filed suit in the Superior Court of California, County of Alameda, against Bright Pattern, Inc. and two of its officers,
alleging that the defendants negotiated a potential acquisition of Bright Pattern by RingCentral fraudulently and in bad faith. The Company seeks its costs incurred
in  negotiating  under  the  Letter  of  Intent  ("LOI")  that  the  parties  entered  into  and  damages  for  lost  opportunity  as  a  result  of  forgoing  another  acquisition
opportunity,  and  attorneys’  fees  and  costs.  On  August  26,  2019,  Bright  Pattern  filed  a  cross-complaint  against  the  Company  and  two  of  its  executive  officers
alleging breach of the LOI as well as tort claims arising from the Company's allegedly inducing Bright Pattern to enter into the LOI and subsequent extensions
while allegedly misstating the timeframe for the proposed transaction. As damages, Bright Pattern seeks audit fees it allegedly incurred, a $5 million break-up fee,
its  alleged  “cash  burn”  during  the  negotiations,  and  unspecified  lost  opportunity  damages.  The  Company  filed  a  demurrer  to  Bright  Pattern’s  amended  cross-
complaint, as well as a related motion to strike. On May 7, 2020, the court denied both the motion to strike and demurrer. The Court has set the matter for trial on
March 14, 2022. This litigation is still in early stages. Based on the information known by the Company as of the date of this filing and the rules and regulations
applicable to the preparation of the Company’s consolidated financial statements, it is not possible to provide an estimated amount of any loss or range of loss that
may occur. The Company intends to vigorously prosecute and defend this lawsuit.

Employee Agreements

The  Company  has  signed  various  employment  agreements  with  executives  and  key  employees  pursuant  to  which  if  the  Company  terminates  their
employment without cause or if the employee terminates his or her employment for good reason following a change of control of the Company, the employees are
entitled  to  receive  certain  benefits,  including  severance  payments,  accelerated  vesting  of  stock  options  and  RSUs,  and  continued  COBRA  coverage.  As  of
December 31, 2020, no triggering events which would cause these provisions to become effective have occurred. Therefore, no liabilities have been recorded for
these agreements in the consolidated financial statements.

Note 9. Stockholders’ Equity

In connection with the Company’s initial public offering, the Company reincorporated in Delaware on September 26, 2013. The Delaware certificate of
incorporation provides for two classes of common stock: Class A and Class B common stock, both with a par value of $0.0001 per share. In addition, the certificate
of incorporation authorizes shares of undesignated preferred stock with a par value of $0.0001 per share. The terms of preferred stock are described below.

Preferred Stock

The  board  of  directors  may,  without  further  action  by  the  stockholders,  fix  the  rights,  preferences,  privileges  and  restrictions  of  up  to  an  aggregate  of
100,000,000 shares of preferred stock in one or more series and authorizes their issuance. These rights, preferences, and privileges could include dividend rights,
conversion  rights,  voting  rights,  terms  of  redemption,  liquidation  preferences,  sinking  fund  terms  and  the  number  of  shares  constituting  any  series  or  the
designation of such series, any or all of which may be greater than the rights of the Class A and Class B common stock. As of December 31, 2020 and 2019, there
were 100,000,000 shares of preferred stock authorized and no shares issued or outstanding.

Class A and Class B Common Stock

The  Company  has  authorized  1,000,000,000  and  250,000,000  shares  of  Class  A  common  stock  and  Class  B  common  stock  for  issuance.  Holders  of
Class  A  common  stock  and  Class  B  common  stock  have  identical  rights  for  matters  submitted  to  a  vote  of  the  Company’s  stockholders.  Holders  of  Class  A
common stock are entitled to one vote per share of Class A common stock and holders of Class B common stock are entitled to 10 votes per share of Class B
common stock. Holders of shares of Class A common stock and Class B common stock vote together as a single class on all matters (including the election of
directors)  except  for  specific  circumstances  that  would  adversely  affect  the  powers,  preferences,  or  rights  of  a  particular  class  of  common  stock.  Subject  to
preferences that may apply to any shares of preferred stock outstanding at the time, holders of Class A and Class B common stock share equally, identically and
ratably, on a per share basis, with respect to any dividend or distribution of cash, property or shares of the Company’s capital stock. Holders of Class A and Class B
common stock also share equally, identically, and ratably in all assets remaining after the payment of any liabilities and liquidation preferences and any accrued or
declared but unpaid dividends, if any, with respect to any outstanding preferred stock at the time. Each share of Class B common stock is convertible at any time at
the option of the holder into one share of Class A common stock. In

87

Table of Contents

addition, each share of Class B common stock will convert automatically to Class A common stock upon: (i) the date specified by an affirmative vote or written
consent  of  holders  of  at  least  67%  of  the  outstanding  shares  of  Class  B  common  stock,  or  (ii)  the  date  on  which  the  number  of  outstanding  shares  of  Class  B
common stock represents less than 10% of the aggregate combined number of outstanding shares of Class A common stock and Class B common stock, or (iii) any
time seven years after the Company's initial public offering (October 2, 2020), when a stockholder owns less than 50% of the shares of Class B common stock that
such holder owned immediately prior to completion of the initial public offering.

Shares of Class A common stock reserved for future issuance were as follows (in thousands):

In September 2013, the Board adopted and the Company’s stockholders approved the 2013 Equity Incentive Plan (“2013 Plan”), which became effective
on September 26, 2013. In connection with the adoption of the 2013 Plan, the Company terminated the 2010 Equity Incentive Plan (“2010 Plan”), under which
stock  options  had  been  granted  prior  to  September  26,  2013.  The  2010  Plan  was  established  in  September  2010,  when  the  2003  Equity  Incentive  Plan  (“2003
Plan”)  was  terminated.  After  the  termination  of  the  2003  and  2010  Plans,  no  additional  options  were  granted  under  these  plans;  however,  options  previously
granted under these plans will continue to be governed by these plans and will be exercisable into shares of Class B common stock. In addition, options authorized
to be granted under the 2003 and 2010 Plans, including forfeitures of previously granted awards, are authorized for grant under the 2013 Plan.

A  total  of  6,200,000  shares  of  Class  A  common  stock  were  originally  reserved  for  issuance  under  the  2013  Plan.  The  2013  Plan  includes  an  annual
increase on the first day of each fiscal year beginning in 2014, equal to the least of: (i) 6,200,000 shares of Class A common stock; (ii) 5% of the outstanding shares
of all classes of common stock as of the last day of the

88

Table of Contents

Company’s immediately preceding fiscal year; or (iii) such other amount as the board of directors may determine. During the year ended December 31, 2020, a
total of 4,347,007 shares of Class A common stock were added to the 2013 Plan in connection with the annual automatic increase provision. As of December 31,
2020, a total of 17,381,894 shares remain available for grant under the 2013 Plan.

The plans permit the grant of stock options and other share-based awards, such as restricted stock units, to employees, officers, directors, and consultants
by the board of directors. Option awards are generally granted with an exercise price equal to the fair market value of the Company’s Class A common stock at the
date of grant. Option awards generally vest according to a graded vesting schedule based on four years of continuous service. On January 29, 2014, the board of
directors approved an amendment to decrease the contractual term of all equity awards issued from the 2013 Plan from 10 years to 7 years for all awards granted
after January 29, 2014. Certain option awards provide for accelerated vesting if there is a change in control (as defined in the option agreement) and early exercise
of options prior to vesting (subject to the Company’s repurchase right).

A  summary  of  option  activity  under  all  of  the  Company’s  equity  incentive  plans  at  December  31,  2020  and  changes  during  the  period  then  ended  is

There were no options granted for the year ended December 31, 2020 and 2019. The total intrinsic value of options exercised during year ended

December 31, 2020, 2019 and 2018 were $343.7 million, $215.5 million, and $74.6 million, respectively.

As of December 31, 2020 and 2019, there was an immaterial  amount of unrecognized share-based compensation expense, net of estimated forfeitures,
related to non-vested stock option grants, which will be recognized on a straight-line basis over the remaining weighted-average vesting periods of approximately
0.2 years and 0.3 years, respectively.

Employee Stock Purchase Plan

The Company's Employee  Stock  Purchase  Plan (“ESPP”) allows eligible  employees  to  purchase  shares  of the Company’s Class A common  stock at a
discounted price, through payroll deductions of up to the lesser of 15% of their eligible compensation or the IRS allowable limit per calendar year. A participant
may purchase a maximum of 3,000 shares during an offering period. The offering periods are for a period of six months and generally start on the first trading day
on or after May 13th and November 13th of each year. At the end of the offering period, the purchase price is set at the lower of: (i) 90% of the fair value of the
Company’s common stock at the beginning of the six month offering period and (ii) 90% of the fair value of the Company’s Class A common stock at the end of
the six month offering period.

The ESPP provides for annual increases in the number of shares available for issuance under the ESPP on the first day of each fiscal year beginning in
fiscal 2014, equal to the least of: (i) 1% of the outstanding shares of all classes of common stock on the last day of the immediately preceding year; (ii) 1,250,000
shares; or (iii) such other amount as may be determined by the board of directors. During the year ended December 31, 2020, a total of 869,401 shares of Class A
common stock were

89

Table of Contents

added to the ESPP Plan in connection with the annual increase provision. At December 31, 2020, a total of 4,670,020 shares were available for issuance under the
ESPP.

Restricted Stock Units

The  2013 Plan  provides  for  the issuance  of  RSUs to employees,  directors,  and  consultants.  RSUs issued  under  the 2013 Plan  generally  vest over  four

Bonus Plan

In  December  2018,  the  Company's  board  of  directors  (the  "Board")  adopted  the  Selective  2019  Key  Employee  Equity  Bonus  Plan  (the  "2019  KEEB
Plan”), which became effective on January 1, 2019, and in December 2019, the Board adopted the Selective 2020 Key Employee Equity Bonus Plan (the "2020
KEEB Plan" and together with the 2019 KEEB Plan the "KEEB Plans"), which became effective on January 1, 2020. Both of the KEEB Plans allow the recipients
to earn fully vested shares of the Company’s Class A Common Stock upon the achievement of quarterly service and performance conditions. During the year ended
December  31,  2020  and  2019,  0.1  million  and  0.1  million  RSUs  were  issued  under  the  KEEB  Plans,  respectively.  The  total  requisite  service  period  of  each
quarterly award is approximately 0.4 years.

The  unrecognized  share-based  compensation  expense  as  of  December  31,  2020  was  approximately  $2.1  million,  which  will  be  recognized  over  the
remaining service period of 0.1 years. The shares issued under the KEEB Plans will be issued from the reserve of shares available for issuance under the 2013 Plan.

In general, it is the Company’s practice and intention to reinvest the earnings of its non-U.S. subsidiaries in those operations. Because the Company’s
non-U.S. subsidiary earnings have previously been subject to the one-time transition tax on foreign earnings required by the 2017 Tax Act, any additional taxes due
with respect to such earnings or the excess of the amount for financial reporting over the tax basis of its foreign investments would generally be limited to foreign

In connection with the acquisition of Connect First on January 14, 2019, a net deferred tax liability of $3.2 million was established, the most significant
component of which is related to the book/tax basis differences associated with the acquired technology and customer relationships. The net deferred tax liability
from this acquisition created an additional source of income to realize deferred tax assets. As the Company continues to maintain a full valuation allowance against
its deferred tax assets, this additional source of income resulted in the release of the Company’s previously recorded valuation allowance against deferred assets.
Consistent with the applicable guidance the release of the valuation allowance of $3.2 million caused by the acquisition was recorded in the consolidated financial
statements outside of acquisition accounting as a tax benefit to the Consolidated Statements of Operations.

As  of  December  31,  2020,  the  Company  has  federal  net  operating  loss  carryforwards  of  approximately  $1.4  billion,  of  which  approximately  $272.9
million  expire  between  2023 and  2037 and  the  remainder  do not  expire.  As of  December  31, 2020, the  Company  had  state  net  operating  loss  carryforwards  of
approximately  $1.1  billion  which  will  begin  to  expire  in  2021.  The  Company  also  has  research  credit  carryforwards  for  federal  and  California  tax  purposes  of
approximately $32.6 million and $24.0 million, respectively, available to reduce future income subject to income taxes. The federal research credit carryforwards
will begin to expire in 2028 and the California research credits carry forward indefinitely.

The Internal Revenue Code of 1986, as amended, imposes restrictions on the utilization of net operating losses in the event of an “ownership change” of a
corporation.  Accordingly,  a  company’s  ability  to  use  net  operating  losses  may  be  limited  as  prescribed  under  Internal  Revenue  Code  Section  382  (“IRC
Section 382”). Events which may cause limitations in the amount of the net operating losses that the Company may use in any one year include, but are not limited
to, a cumulative ownership change of more than 50% over a three-year period. Utilization of the federal and state net operating losses may be subject to substantial
annual limitation due to the ownership change limitations provided by the IRC Section 382 and similar state provisions.

The Company’s management believes that, based on a number of factors, it is more likely than not, that all or some portion of the deferred tax assets will
not be realized; and accordingly, for the year ended December 31, 2020, the Company has provided a valuation allowance against the Company’s U.S. net deferred
tax  assets.  The  net  change  in  the  valuation  allowance  for  the  years  ended  December  31,  2020  and  2019  was  an  increase  of  $75.3  million,  $86.0  million,
respectively.

In accordance with ASC 740-10, Income Taxes, the Company has adopted the accounting policy that interest and penalties recognized are classified as

part of its income taxes.

The Company does not anticipate that its total unrecognized tax benefits will significantly change due to settlement of examination or the expiration of
statute of limitations during the next 12 months. Due to the full valuation allowance at December 31, 2020, current adjustments to the unrecognized tax benefit will
have no impact on our effective income tax rate. Any adjustments made after the valuation allowance is released will have an impact on the tax rate.

The Company files U.S. and foreign income tax returns with varying statutes of limitations. Due to the Company’s net carry-over of unused operating

losses and tax credits, all years from 2003 forward remain subject to future examination by tax authorities.

Note 12. Basic and Diluted Net Loss Per Share

Basic net loss per share is computed by dividing the net loss by the weighted-average number of shares of common stock outstanding during the period.
Diluted net loss per share is computed by giving effect to all potential shares of common stock, stock options, restricted stock units, ESPP, and convertible senior
notes, to the extent dilutive. For the years ended December 31, 2020, 2019 and 2018, all such common stock equivalents have been excluded from diluted net loss
per share as the effect to net loss per share would be anti-dilutive.

The following table sets forth the computation of the Company’s basic and diluted net loss per share of common stock (in thousands, except per share

data):

       Since  the  Company  expects  to  settle  the  principal  amount  on  its  outstanding  2023,  2025,  and  2026  Notes  in  cash  and  any  excess  in  cash  or  shares  of  the
Company’s Class A Common Stock, the Company uses the treasury stock method for calculating any potential dilutive effect of the conversion spread on diluted
net income per share, if applicable. The conversion spread will have a dilutive impact on diluted net income per share of common stock when the average market
price of the Company’s Class A Common Stock for a given period exceeds the conversion price of $81.45, $360.43, and $424.03 per share for the 2023, 2025, and
2026 Notes, respectively.

93

Table of Contents

The denominator for diluted net income per share does not include any effect from the capped call transactions the Company entered into concurrently
with the issuance of the Notes as this effect would be anti-dilutive. In the event of conversion of a 2023, 2025, or 2026 Note, if shares are delivered to the Company
under the capped call, they will offset the dilutive effect of the shares that the Company would issue under the Notes.

Note 13. 401(k) Plan

The Company has a qualified defined contribution plan under Section 401(k) of the Internal Revenue Code covering eligible employees. Substantially all
of the U.S. employees are eligible to make contributions to the 401(k) plan. The Company matches 401(k) based on the amount of the employees’ contributions
subject to certain limitations. Employer contributions were $5.4 million, $4.1 million, and $2.9 million for the years ended December 31, 2020, 2019 and 2018.

ITEM 9.    CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE

None.

ITEM 9A.    CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

Under the supervision and with the participation of our management, including our chief executive officer and chief financial officer, we conducted an
evaluation  of  the  effectiveness  of  the  design  and  operation  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.

In designing and evaluating our disclosure controls and procedures, management recognizes that any disclosure controls and procedures, no matter how
well designed and operated, can provide only reasonable, not absolute, assurance of achieving the desired control objectives. In addition, the design of disclosure
controls and procedures must reflect the fact that there are resource constraints and that management is required to apply its judgment in evaluating the benefits of
possible controls and procedures relative to their costs.

Based  on  management’s  evaluation,  our  chief  executive  officer  and  chief  financial  officer  concluded  that  our  disclosure  controls  and  procedures  are
designed to, and are effective to, provide assurance at a reasonable level that the information we are required to disclose in reports that we file or submit under the
Exchange Act is recorded, processed, summarized and reported within the time periods specified in SEC rules and forms, and that such information is accumulated
and communicated to our management, including our chief executive officer and chief financial officer, as appropriate, to allow timely decisions regarding required
disclosures.

Management’s Annual Report on Internal Controls Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange
Act Rules 13a-15(f) and 15d-15(f). Under the supervision and with the participation of our management, including our chief executive officer and chief financial
officer,  we  conducted  an  evaluation  of  the  effectiveness  of  our  internal  control  over  financial  reporting  as  of  December  31,  2020  based  on  the  guidelines
established in the Internal Control—Integrated Framework (2013 framework) issued by the Committee of Sponsoring Organizations of the Treadway Commission
(“COSO”). Our internal control over financial reporting includes policies and procedures that provide reasonable assurance regarding the reliability of financial
reporting and the preparation of financial statements for external reporting purposes in accordance with U.S. generally accepted accounting principles.

The effectiveness of our internal control over financial reporting as of December 31, 2020 has been audited by KPMG LLP, an independent registered

public accounting firm, as stated in its report which is included in Item 8 of this Annual Report on Form 10-K.

Changes in Internal Control Over Financial Reporting

There are no changes in our internal control over financial  reporting identified  in connection with the evaluation  required by Rule 13a-15(d)  and 15d-
15(d) of the Exchange Act that occurred during the quarter ended December 31, 2020, that have materially affected, or are reasonably likely to materially affect,
our internal control over financial reporting.

We  have  not  experienced  any  material  impact  to  our  internal  controls  over  financial  reporting  although  since  March  2020 most  of  our  employees  and
extended  workforce  are  now  working  remotely  due  to  the  COVID-19  pandemic.  We  are  continually  monitoring  and  assessing  the  COVID-19  situation  on  our
internal controls to address impacts to their design, implementation and operating effectiveness.

Inherent Limitations on Effectiveness of Controls

Our management, including our chief executive officer and chief financial officer, do not expect that our disclosure controls 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. Further, the design of a control system must reflect the fact that there are resource constraints, and the
benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls

95

Table of Contents

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 controls. The design of any system of
controls  is  also  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 policies or procedures may deteriorate. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud
may occur and not be detected.

RINGCENTRAL, INC.

AMENDED AND RESTATED EMPLOYEE STOCK PURCHASE PLAN

1.

Purpose.  The  purpose  of  the  Plan  is  to  provide  employees  of  the  Company  and  its  Designated  Companies  with  an
opportunity  to  purchase  Common  Stock  through  accumulated  Contributions.  The  Company’s  intends  for  the  Plan  to  have  two
components: a Code Section 423 Component (“423 Component”) and a non-Code Section 423 Component (“Non-423 Component”).
The Company’s intention is to have 423 Component of the Plan qualify as an “employee stock purchase plan” under Section 423 of
the  Code.  The  provisions  of  the  423  Component,  accordingly,  will  be  construed  so  as  to  extend  and  limit  Plan  participation  in  a
uniform and nondiscriminatory basis consistent with the requirements of Section 423 of the Code. In addition, this Plan authorizes
the grant of an option to purchase shares of Common Stock under the Non-423 Component that does not qualify as an “employee
stock  purchase  plan”  under  Section  423  of  the  Code;  such  an  option  will  be  granted  pursuant  to  rules,  procedures  or  sub-plans
adopted by the Administrator designed to achieve tax, securities laws or other objectives for Eligible Employees and the Company.
Except  as  otherwise  provided  herein,  the  Non-423  Component  will  operate  and  be  administered  in  the  same  manner  as  the  423
Component.

purposes of this subsection, the acquisition of additional stock by any one Person, who is considered to own more than fifty percent
(50%) of the total voting power of the stock of the Company will not be considered a Change in Control; or

(ii)

A change in the effective control of the Company which occurs on the date that a majority of members

majority of the members of the Board prior to the date of the appointment or election. For purposes of this clause (ii), if any Person
is considered to be in effective control of the Company, the acquisition of additional control of the Company by the same Person will
not be considered a Change in Control; or

(iii)

A change in the ownership of a substantial portion of the Company’s assets which occurs on the date

Code or U.S. Treasury Regulation thereunder will include such section or regulation, any valid regulation or other official applicable

(1)  day  following  the  commencement  of  such  leave.  The  Administrator,  in  its  discretion,  from  time  to  time  may,  prior  to  an
Enrollment Date for all options to be granted on such Enrollment Date in an Offering, determine (for each Offering under the 423

to  each  Offering  under  the  423  Component  in  an  identical  manner  to  all  highly  compensated  individuals  of  the  Employer  whose
employees are participating in that Offering. Each exclusion shall be applied with respect to an Offering under a 423 Component in a
manner  complying  with  U.S.  Treasury  Regulation  Section  1.423‑2(e)(2)(ii).  Such  exclusions  may  be  applied  with  respect  to  an

would be attributed to such Eligible Employee pursuant to Section 424(d) of the Code) would own capital stock of the Company or
any Parent or Subsidiary  of the Company and/or hold outstanding  options to purchase such stock possessing five percent (5%) or
more of the total combined voting power or value of all classes of the capital stock of the Company or of any Parent or Subsidiary of
the  Company,  or  (ii)  to  the  extent  that  his  or  her  rights  to  purchase  stock  under  all  employee  stock  purchase  plans  (as  defined  in
Section 423 of the Code) of the Company or any Parent or Subsidiary of the Company accrues at a rate, which exceeds twenty-five
thousand dollars ($25,000) worth of stock (determined at the Fair Market Value of the stock at the time such option is granted) for
each calendar year in which such option is outstanding at any time, as determined in accordance with Section 423 of the Code and
the regulations thereunder.

4.

Offering  Periods.  The  Plan  will  be  implemented  by  consecutive  Offering  Periods  with  a  new  Offering  Period
commencing on the first Trading Day on or after May 13 and November 13 each year, or on such other date as the Administrator
will  determine.  The  Administrator  will  have  the  power  to  change  the  duration  of  Offering  Periods  (including  the  commencement
dates  thereof)  with  respect  to  future  Offerings  without  stockholder  approval  if  such  change  is  announced  prior  to  the  scheduled
beginning  of  the  first  Offering  Period  to  be  affected  thereafter;  provided,  however,  that  no  Offering  Period  may  last  more  than
twenty-seven (27) months.

5.

Participation.  An  Eligible  Employee  may  participate  in  the  Plan  pursuant  to  Section  3(b)  by  (i)  submitting  to  the
Company’s stock administration office (or its designee), on or before a date determined by the Administrator prior to an applicable
Enrollment Date, a properly completed subscription agreement authorizing Contributions in the form provided by the Administrator
for such purpose, or (ii) following an electronic or other enrollment procedure determined by the Administrator.

6.

Contributions.

(a)

At the time a Participant enrolls in the Plan pursuant to Section 5, he or she will elect to have Contributions (in
the form of payroll deductions or otherwise, to the extent permitted by the Administrator) made on each pay day during the Offering
Period in an amount not exceeding fifteen percent (15%) of the Compensation, which he or she receives on each pay day during the
Offering Period (for illustrative purposes, should a pay day occur on an Exercise Date, a Participant will have any payroll deductions
made on such day applied to his or her account under the then-current Purchase Period or Offering Period). The Administrator, in its
sole discretion, may permit all Participants in a specified Offering to contribute amounts to the Plan through payment by cash, check
or  other  means  set  forth  in  the  subscription  agreement  prior  to  each  Exercise  Date  of  each  Purchase  Period.  A  Participant’s
subscription agreement will remain in effect for successive Offering Periods unless terminated as provided in Section 10 hereof.

(b)

In  the  event  Contributions  are  made  in  the  form  of  payroll  deductions,  such  payroll  deductions  for  a
Participant will commence on the first pay day following the Enrollment Date and will end on the last pay day prior to the Exercise
Date of such Offering Period to which such authorization is applicable, unless sooner terminated by the Participant as provided in
Section 10 hereof.

(c)

All  Contributions  made  for  a  Participant  will  be  credited  to  his  or  her  account  under  the  Plan  and

Contributions will be made in whole percentages only. A Participant may not make any additional payments into such account.

(d)

A Participant may discontinue his or her participation in the Plan as provided in Section 10. Except as may be
permitted by the Administrator, as determined in its sole discretion, a Participant may not change the rate of his or her Contributions
during an Offering Period.

(e)

Notwithstanding  the  foregoing,  to  the  extent  necessary  to  comply  with  Section  423(b)(8)  of  the  Code  and
Section 3(d), a Participant’s Contributions may be decreased to zero percent (0%) at any time during a Purchase Period. Subject to
Section  423(b)(8)  of  the  Code  and  Section  3(b)  hereof,  Contributions  will  recommence  at  the  rate  originally  elected  by  the
Participant  effective  as  of  the  beginning  of  the  first  Purchase  Period  scheduled  to  end  in  the  following  calendar  year,  unless
terminated by the Participant as provided in Section 10.

(f)

Notwithstanding any provisions to the contrary in the Plan, the Administrator may allow Eligible Employees
to  participate  in  the  Plan  via  cash  contributions  instead  of  payroll  deductions  if  (i)  payroll  deductions  are  not  permitted  under
applicable local law, (ii) the Administrator determines that cash contributions are permissible under Section 423 of the Code or (iii)
for Participants participating in the Non-423 Component.

(g)

At the time the option is exercised, in whole or in part, or at the time some or all of the Common Stock issued
under the Plan is disposed of (or any other time that a taxable event related to the Plan occurs), the Participant must make adequate
provision  for the  Company’s  or  Employer’s  federal,  state,  local  or any  other  tax  liability  payable  to any  authority  including  taxes
imposed by jurisdictions outside of the U.S., national insurance, social security or other tax withholding obligations, if any, which
arise upon the exercise of the option or the

disposition of the Common Stock (or any other time that a taxable event related to the Plan occurs). At any time, the Company or the
Employer may, but will not be obligated to, withhold from the Participant’s compensation the amount necessary for the Company or
the Employer to meet applicable withholding obligations, including any withholding required to make available to the Company or
the Employer any tax deductions or benefits attributable to sale or early disposition of Common Stock by the Eligible Employee. In
addition, the Company or the Employer may, but will not be obligated to, withhold from the proceeds of the sale of Common Stock
or  any  other  method  of  withholding  the  Company  or  the  Employer  deems  appropriate  to  the  extent  permitted  by  U.S.  Treasury
Regulation Section 1.423‑2(f).

7.

Grant  of  Option.  On  the  Enrollment  Date  of  each  Offering  Period,  each  Eligible  Employee  participating  in  such
Offering Period will be granted an option to purchase on each Exercise Date during such Offering Period (at the applicable Purchase
Price)  up  to  a  number  of  shares  of  Common  Stock  determined  by  dividing  such  Eligible  Employee’s  Contributions  accumulated
prior to such Exercise Date and retained in the Eligible Employee’s account as of the Exercise Date by the applicable Purchase Price;
provided that in no event will an Eligible Employee be permitted to purchase during each Purchase Period more than 3,000 shares of
Common  Stock  (subject  to  any  adjustment  pursuant  to  Section  19)  and  provided  further  that  such  purchase  will  be  subject  to  the
limitations set forth in Sections 3(c) and 13. The Eligible Employee may accept the grant of such option with respect to any Offering
Period  under  the  Plan,  by  electing  to  participate  in  the  Plan  in  accordance  with  the  requirements  of  Section  5.  The  Administrator
may, for future Offering Periods, increase or decrease, in its absolute discretion, the maximum number of shares of Common Stock
that  an  Eligible  Employee  may  purchase  during  each  Purchase  Period  of  an  Offering  Period.  Exercise  of  the  option  will  occur  as
provided  in  Section  8,  unless  the  Participant  has  withdrawn  pursuant  to  Section  10.  The  option  will  expire  on  the  last  day  of  the
Offering Period.

8.

Exercise of Option.

(a)

Unless a Participant withdraws from the Plan as provided in Section 10, his or her option for the purchase of
shares of Common Stock will be exercised automatically on the Exercise Date, and the maximum number of full shares subject to
the option will be purchased for such Participant at the applicable Purchase Price with the accumulated Contributions from his or her
account. No fractional shares of Common Stock will be purchased. Any Contributions accumulated in a Participant’s account after
the Exercise Date, including any Contributions which are not sufficient to purchase a full share, will be automatically returned to the
Participant as soon as administratively practicable following the Exercise Date. During a Participant’s lifetime, a Participant’s option
to purchase shares hereunder is exercisable only by him or her.

(b)

If the Administrator determines that, on a given Exercise Date, the number of shares of Common Stock with
respect  to  which  options  are  to  be  exercised  may  exceed  (i)  the  number  of  shares  of  Common  Stock  that  were  available  for  sale
under the Plan on the Enrollment Date of the applicable Offering Period, or (ii) the number of shares of Common Stock available for
sale under the Plan on such Exercise Date, the Administrator may in its sole discretion (x) provide that the Company will make a pro
rata allocation of the shares of Common Stock available for purchase on such Enrollment Date or Exercise Date, as applicable, in as
uniform a

manner as will be practicable and as it will determine in its sole discretion to be equitable among all Participants exercising options
to purchase Common Stock on such Exercise Date, and continue all Offering Periods then in effect or (y) provide that the Company
will make a pro rata allocation of the shares available for purchase on such Enrollment Date or Exercise Date, as applicable, in as
uniform  a  manner  as  will  be  practicable  and  as  it  will  determine  in  its  sole  discretion  to  be  equitable  among  all  participants
exercising  options  to  purchase  Common  Stock  on  such  Exercise  Date,  and  terminate  any  or  all  Offering  Periods  then  in  effect
pursuant  to  Section  20.  The  Company  may  make  a  pro  rata  allocation  of  the  shares  available  on  the  Enrollment  Date  of  any
applicable Offering Period pursuant to the preceding sentence, notwithstanding any authorization of additional shares for issuance
under the Plan by the Company’s stockholders subsequent to such Enrollment Date.

9.

Delivery.  As  soon  as  reasonably  practicable  after  each  Exercise  Date  on  which  a  purchase  of  shares  of  Common
Stock occurs, the Company will arrange the delivery to each Participant of the shares purchased upon exercise of his or her option in
a form determined by the Administrator (in its sole discretion) and pursuant to rules established by the Administrator. The Company
may  permit  or  require  that  shares  be  deposited  directly  with  a  broker  designated  by  the  Company  or  to  a  designated  agent  of  the
Company, and the Company may utilize electronic or automated methods of share transfer. The Company may require that shares be
retained  with  such  broker  or  agent  for  a  designated  period  of  time  and/or  may  establish  other  procedures  to  permit  tracking  of
disqualifying dispositions of such shares. No Participant will have any voting, dividend, or other stockholder rights with respect to
shares of Common Stock subject to any option granted under the Plan until such shares have been purchased and delivered to the
Participant as provided in this Section 9.

10. Withdrawal.

(a)

A Participant may withdraw all but not less than all the Contributions credited to his or her account and not yet
used to exercise his or her option under the Plan at any time by (i) submitting to the Company’s stock administration office (or its
designee) a written notice of withdrawal in the form determined by the Administrator for such purpose (which may be similar to the
form attached hereto as Exhibit B), or (ii) following an electronic or other withdrawal procedure determined by the Administrator.
All of the Participant’s Contributions credited to his or her account will be paid to such Participant promptly after receipt of notice of
withdrawal and such Participant’s option for the Offering Period will be automatically terminated, and no further Contributions for
the purchase of shares will be made for such Offering Period. If a Participant withdraws from an Offering Period, Contributions will
not resume at the beginning of the succeeding Offering Period, unless the Participant re-enrolls in the Plan in accordance with the
provisions of Section 5.

(b)

A  Participant’s  withdrawal  from  an  Offering  Period  will  not  have  any  effect  upon  his  or  her  eligibility  to
participate in any similar plan that may hereafter be adopted by the Company or in succeeding Offering Periods that commence after
the termination of the Offering Period from which the Participant withdraws.

11.

Termination of Employment. Upon a Participant’s ceasing to be an Eligible Employee, for any reason, he or she will
be  deemed  to  have  elected  to  withdraw  from  the  Plan  and  the  Contributions  credited  to  such  Participant’s  account  during  the
Offering Period but not

yet used to purchase shares of Common Stock under the Plan will be returned to such Participant or, in the case of his or her death, to
the  person  or  persons  entitled  thereto  under  Section  15,  and  such  Participant’s  option  will  be  automatically  terminated.  Unless
determined otherwise by the Administrator in a manner that, with respect to an Offering under the 423 Component, is permitted by,
and compliant with, Section 423 of the Code, a Participant whose employment transfers between entities through a termination with
an immediate rehire (with no break in service) by the Company or a Designated Company shall not be treated as terminated under
the Plan; however, no Participant shall be deemed to switch from an Offering under the Non-423 Component to an Offering under
the 423 Component or vice versa unless (and then only to the extent) such switch would not cause the 423 Component or any Option
thereunder to fail to comply with Section 423 of the Code.

12.

Interest.  No  interest  will  accrue  on  the  Contributions  of  a  participant  in  the  Plan,  except  as  may  be  required  by
Applicable  Law,  as  determined  by  the  Company,  and  if  so  required  by  the  laws  of  a  particular  jurisdiction,  shall,  with  respect  to
Offerings under the 423 Component, apply to all Participants in the relevant Offering, except to the extent otherwise permitted by
U.S. Treasury Regulation Section 1.423‑2(f).

13.

Stock.

(a)

Subject  to  adjustment  upon  changes  in  capitalization  of  the  Company  as  provided  in  Section  19  hereof,  the
maximum  number  of  shares  of  Common  Stock  that  will  be  made  available  for  sale  under  the  Plan  will  be  1,250,000  shares  of
Common Stock. The number of shares of Common Stock available for issuance under the Plan will be increased on the first day of
each Fiscal Year beginning with the 2014 Fiscal Year equal to the least of (i) 1,250,000 shares of Common Stock, (ii) one percent
(1%) of the outstanding shares of all classes of the Company’s common stock on the last day of the immediately preceding Fiscal
Year, or (iii) an amount determined by the Administrator.

(b)

Until  the  shares  of  Common  Stock  are  issued  (as  evidenced  by  the  appropriate  entry  on  the  books  of  the
Company or of a duly authorized  transfer agent of the Company),  a Participant  will only have the rights of an unsecured creditor
with respect to such shares, and no right to vote or receive dividends or any other rights as a stockholder will exist with respect to
such shares.

(c)

Shares of Common Stock to be delivered to a Participant under the Plan will be registered in the name of the

Participant or in the name of the Participant and his or her spouse.

14.

Administration.  The  Plan  will  be  administered  by  the  Board  or  a  Committee  appointed  by  the  Board,  which
Committee  will  be  constituted  to  comply  with  Applicable  Laws.  The  Administrator  will  have  full  and  exclusive  discretionary
authority  to  construe,  interpret  and  apply  the  terms  of  the  Plan,  to  designate  separate  Offerings  under  the  Plan,  to  designate
Subsidiaries and Affiliates as participating in the 423 Component or Non-423 Component, to determine eligibility, to adjudicate all
disputed  claims  filed  under  the  Plan  and  to  establish  such  procedures  that  it  deems  necessary  for  the  administration  of  the  Plan
(including, without limitation, to adopt such procedures and sub-plans as are necessary or appropriate to permit the participation in
the Plan by employees who are foreign nationals or employed outside the U.S.,

the terms of which sub-plans may take precedence over other provisions of this Plan, with the exception of Section 13(a) hereof, but
unless otherwise superseded by the terms of such sub-plan, the provisions of this Plan shall govern the operation of such sub-plan).
Unless  otherwise  determined  by  the  Administrator,  the  employees  eligible  to  participate  in  each  sub-plan  will  participate  in  a
separate Offering and will be in the Non-423 Component, unless such designation would cause the 423 Component to violate the
requirements  of  Section  423  of  the  Code.  Without  limiting  the  generality  of  the  foregoing,  the  Administrator  is  specifically
authorized  to  adopt  rules  and  procedures  regarding  eligibility  to  participate,  the  definition  of  Compensation,  handling  of
Contributions,  making  of  Contributions  to  the  Plan  (including,  without  limitation,  in  forms  other  than  payroll  deductions),
establishment of bank or trust accounts to hold Contributions, payment of interest, conversion of local currency, obligations to pay
payroll  tax,  determination  of  beneficiary  designation  requirements,  withholding  procedures  and  handling  of  stock  certificates  that
vary  with  applicable  local  requirements.  The  Administrator  also  is  authorized  to  determine  that,  to  the  extent  permitted  by  U.S.
Treasury  Regulation  Section 1.423‑2(f),  the terms of an option  granted  under the Plan or an Offering  to citizens  or residents  of a
non-U.S.  jurisdiction  will  be  less  favorable  than  the  terms  of  options  granted  under  the  Plan  or  the  same  Offering  to  employees
resident solely in the U.S. Every finding, decision and determination made by the Administrator will, to the full extent permitted by
law, be final and binding upon all parties.

15.

Designation of Beneficiary.

(a)

If permitted by the Administrator, a Participant may file a designation of a beneficiary who is to receive any
shares  of  Common  Stock  and  cash,  if  any,  from  the  Participant’s  account  under  the  Plan  in  the  event  of  such  Participant’s  death
subsequent to an Exercise Date on which the option is exercised but prior to delivery to such Participant of such shares and cash. In
addition, if permitted by the Administrator, a Participant may file a designation of a beneficiary who is to receive any cash from the
Participant’s account under the Plan in the event of such Participant’s death prior to exercise of the option. If a Participant is married
and the designated beneficiary is not the spouse, spousal consent will be required for such designation to be effective.

(b)

Such designation of beneficiary may be changed by the Participant at any time by notice in a form determined
by the Administrator. In the event of the death of a Participant and in the absence of a beneficiary validly designated under the Plan
who  is  living  at  the  time  of  such  Participant’s  death,  the  Company  will  deliver  such  shares  and/or  cash  to  the  executor  or
administrator  of the estate  of the Participant,  or if no such executor  or administrator  has been appointed  (to the knowledge  of the
Company), the Company, in its discretion, may deliver such shares and/or cash to the spouse or to any one or more dependents or
relatives  of  the  Participant,  or  if  no  spouse,  dependent  or  relative  is  known  to  the  Company,  then  to  such  other  person  as  the
Company may designate.

(c)

All beneficiary designations will be in such form and manner as the Administrator may designate from time to
time.  Notwithstanding  Sections  15(a)  and  (b)  above,  the  Company  and/or  the  Administrator  may  decide  not  to  permit  such
designations by Participants in non-U.S. jurisdictions to the extent permitted by U.S. Treasury Regulation Section 1.423‑2(f).

16.

Transferability. Neither Contributions credited to a Participant’s account nor any rights with regard to the exercise of
an option or to receive shares of Common Stock under the Plan may be assigned, transferred, pledged or otherwise disposed of in
any way (other than by will, the laws of descent and distribution or as provided in Section 15 hereof) by the Participant. Any such
attempt at assignment, transfer, pledge or other disposition will be without effect, except that the Company may treat such act as an
election to withdraw funds from an Offering Period in accordance with Section 10 hereof.

17.

Use  of  Funds.  The  Company  may  use  all  Contributions  received  or  held  by  it  under  the  Plan  for  any  corporate
purpose, and the Company will not be obligated to segregate such Contributions except under Offerings or for Participants in the
Non-423  Component  for  which  Applicable  Laws  require  that  Contributions  to  the  Plan  by  Participants  be  segregated  from  the
Company’s  general  corporate  funds  and/or  deposited  with  an  independent  third  party.  Until  shares  of  Common  Stock  are  issued,
Participants will only have the rights of an unsecured creditor with respect to such shares.

18.

Reports. Individual accounts will be maintained for each Participant in the Plan. Statements of account will be given
to  participating  Eligible  Employees  at  least  annually,  which  statements  will  set  forth  the  amounts  of  Contributions,  the  Purchase
Price, the number of shares of Common Stock purchased and the remaining cash balance, if any.

19.

Adjustments, Dissolution, Liquidation, Merger or Change in Control.

(a)

Adjustments. In the event that any dividend or other distribution (whether in the form of cash, Common Stock,
other securities, or other property), recapitalization, stock split, reverse stock split, reorganization, merger, consolidation, split-up,
spin-off,  combination,  repurchase,  or  exchange  of  Common  Stock  or  other  securities  of  the  Company,  or  other  change  in  the
corporate  structure  of  the  Company  affecting  the  Common  Stock  occurs,  the  Administrator,  in  order  to  prevent  dilution  or
enlargement of the benefits or potential benefits intended to be made available under the Plan, will, in such manner as it may deem
equitable, adjust the number and class of Common Stock that may be delivered under the Plan, the Purchase Price per share and the
number of shares of Common Stock covered by each option under the Plan that has not yet been exercised, and the numerical limits
of Sections 7 and 13.

(b)

Dissolution  or  Liquidation.  In  the  event  of  the  proposed  dissolution  or  liquidation  of  the  Company,  any
Offering  Period  then  in  progress  will  be  shortened  by  setting  a  New  Exercise  Date,  and  will  terminate  immediately  prior  to  the
consummation of such proposed dissolution or liquidation, unless provided otherwise by the Administrator. The New Exercise Date
will  be  before  the  date  of  the  Company’s  proposed  dissolution  or  liquidation.  The  Administrator  will  notify  each  Participant  in
writing or electronically, prior to the New Exercise Date, that the Exercise Date for the Participant’s option has been changed to the
New Exercise Date and that the Participant’s option will be exercised automatically on the New Exercise Date, unless prior to such
date the Participant has withdrawn from the Offering Period as provided in Section 10 hereof.

(c)

Merger or Change in Control. In the event of a merger or Change in Control, each outstanding option will be
assumed or an equivalent option substituted by the successor corporation or a Parent or Subsidiary of the successor corporation. In
the event that

the successor corporation refuses to assume or substitute for the option, the Offering Period with respect to which such option relates
will be shortened by setting a New Exercise Date on which such Offering Period shall end. The New Exercise Date will occur before
the  date  of  the  Company’s  proposed  merger  or  Change  in  Control.  The  Administrator  will  notify  each  Participant  in  writing  or
electronically  prior  to  the  New  Exercise  Date,  that  the  Exercise  Date  for  the  Participant’s  option  has  been  changed  to  the  New
Exercise Date and that the Participant’s option will be exercised automatically on the New Exercise Date, unless prior to such date
the Participant has withdrawn from the Offering Period as provided in Section 10 hereof.

20.

Amendment or Termination.

(a)

The Administrator, in its sole discretion, may amend, suspend, or terminate the Plan, or any part thereof, at
any  time  and  for  any  reason.  If  the  Plan  is  terminated,  the  Administrator,  in  its  discretion,  may  elect  to  terminate  all  outstanding
Offering  Periods  either  immediately  or  upon  completion  of  the  purchase  of  shares  of  Common  Stock  on  the  next  Exercise  Date
(which  may  be  sooner  than  originally  scheduled,  if  determined  by  the  Administrator  in  its  discretion),  or  may  elect  to  permit
Offering  Periods  to  expire  in  accordance  with  their  terms  (and  subject  to  any  adjustment  pursuant  to  Section  19).  If  the  Offering
Periods are terminated prior to expiration, all amounts then credited to Participants’  accounts that have not been used to purchase
shares of Common Stock will be returned to the Participants (without interest thereon, except as otherwise required under Applicable
Laws, as further set forth in Section 12 hereof) as soon as administratively practicable.

(b) Without stockholder consent and without limiting Section 20(a), the Administrator will be entitled to change
the Offering Periods or Purchase Periods, designate separate Offerings, limit the frequency and/or number of changes in the amount
withheld  during  an  Offering  Period,  establish  the  exchange  ratio  applicable  to  amounts  withheld  in  a  currency  other  than  U.S.
dollars,  permit  Contributions  in  excess  of  the  amount  designated  by  a  Participant  in  order  to  adjust  for  delays  or  mistakes  in  the
Company’s  processing  of  properly  completed  Contribution  elections,  establish  reasonable  waiting  and  adjustment  periods  and/or
accounting  and  crediting  procedures  to  ensure  that  amounts  applied  toward  the  purchase  of  Common  Stock  for  each  Participant
properly correspond with Contribution amounts, and establish such other limitations or procedures as the Administrator determines
in its sole discretion advisable that are consistent with the Plan.

(c)

In  the  event  the  Administrator  determines  that  the  ongoing  operation  of  the  Plan  may  result  in  unfavorable
financial accounting consequences, the Administrator may, in its discretion and, to the extent necessary or desirable, modify, amend
or terminate the Plan to reduce or eliminate such accounting consequence including, but not limited to:

amending  the  Plan  to  conform  with  the  safe  harbor  definition  under  the  Financial  Accounting
Standards  Board  Accounting  Standards  Codification  Topic  718  (or  any  successor  thereto),  including  with  respect  to  an  Offering
Period underway at the time;

(i)

Purchase Period underway at the time of the change in Purchase Price;

(ii)

altering the Purchase Price for any Offering Period or Purchase Period including an Offering Period or

Offering Period or Purchase Period underway at the time of the Administrator action;

(iii)

shortening  any  Offering  Period  or  Purchase  Period  by  setting  a  New  Exercise  Date,  including  an

(iv)

reducing  the  maximum  percentage  of  Compensation  a  Participant  may  elect  to  set  aside  as

Contributions; and

(v)

reducing  the  maximum  number  of  shares  of  Common  Stock  a  Participant  may  purchase  during  any

Offering Period or Purchase Period.

Such modifications or amendments will not require stockholder approval or the consent of any Plan Participants.

21.

Notices. All notices or other communications by a Participant to the Company under or in connection with the Plan
will be deemed to have been duly given when received in the form and manner specified by the Company at the location, or by the
person, designated by the Company for the receipt thereof.

22.

Conditions Upon Issuance of Shares. Shares of Common Stock will not be issued with respect to an option unless the
exercise of such option and the issuance and delivery of such shares pursuant thereto will comply with all applicable provisions of
law,  domestic  or  foreign,  including,  without  limitation,  the  Securities  Act  of  1933,  as  amended,  the  Exchange  Act,  the  rules  and
regulations promulgated thereunder, and the requirements of any stock exchange upon which the shares may then be listed, and will
be further subject to the approval of counsel for the Company with respect to such compliance.

As a condition to the exercise of an option, the Company may require the person exercising such option to represent
and  warrant  at  the  time  of  any  such  exercise  that  the  shares  are  being  purchased  only  for  investment  and  without  any  present
intention to sell or distribute such shares if, in the opinion of counsel for the Company, such a representation is required by any of
the aforementioned applicable provisions of law.

23.

Code Section 409A. The 423 Component of the Plan is exempt from the application of Code Section 409A and any
ambiguities herein will be interpreted to so be exempt from Code Section 409A. In furtherance of the foregoing and notwithstanding
any provision in the Plan to the contrary, if the Administrator determines that an option granted under the Plan may be subject to
Code Section 409A or that any provision in the Plan would cause an option under the Plan to be subject to Code Section 409A, the
Administrator may amend the terms of the Plan and/or of an outstanding option granted under the Plan, or take such other action the
Administrator  determines  is  necessary  or  appropriate,  in  each  case,  without  the  Participant’s  consent,  to  exempt  any  outstanding
option or future option that may be granted under the Plan from or to allow any such options to comply with Code Section 409A, but
only to the extent any such amendments or action by the Administrator would not violate Code Section 409A. Notwithstanding the
foregoing, the Company shall have no liability to a Participant or any other party if the option to purchase Common Stock under the
Plan that is intended to be exempt from or compliant with Code Section 409A is not so exempt or compliant or for any action taken
by the Administrator with respect thereto. The Company makes no representation that the option to purchase Common Stock under
the Plan is compliant with Code Section 409A.

24.

Term of Plan. The Plan will become effective upon the earlier to occur of its adoption by the Board or its approval by
the stockholders of the Company. It will continue in effect for a term of twenty (20) years, unless sooner terminated under Section
20.

Governing Law. The Plan shall be governed by, and construed in accordance with, the laws of the State of Delaware

EXHIBIT A

RINGCENTRAL, INC.

AMENDED AND RESTATED EMPLOYEE STOCK PURCHASE PLAN

GLOBAL SUBSCRIPTION AGREEMENT

1.

I  hereby  elect  to  participate  in  the  RingCentral,  Inc.  Amended  and  Restated  Employee  Stock  Purchase  Plan  (the
“Plan”) and subscribe to purchase shares of the Company’s Class A Common Stock (“Shares”) in accordance with the Plan and this
Global Subscription Agreement, including the additional Terms and Conditions for my country attached hereto (the “Appendix” and,
together with the Global Subscription Agreement, this “Agreement”). Capitalized terms used but not defined in this Agreement will
have the meanings set forth in the Plan.

2.

I hereby authorize payroll deductions from each paycheck in the amount I have specified to the Company, from 1% to
15%  (in  whole  numbers  only)  of  my  Compensation,  on  each  payday  during  the  Offering  Period  in  accordance  with  the  Plan.  I
understand that said payroll deductions will be accumulated for the purchase of Shares at the applicable Purchase Price determined
in accordance with the Plan. I understand that, if I do not withdraw from an Offering Period and remain an Eligible Employee, any
accumulated payroll deductions will be used to automatically exercise my option and purchase Shares under the Plan.

3.
Purchase Period.

I  understand  that  I  may  suspend  my  Contribution  and  reduce  my  percentage  to  0%  without  withdrawing  from  the

4.

I understand that I may decrease my Contribution percentage one time during each Offering Period, and that I may

increase my Contribution percentage only during the next open enrollment period, to be effective for the following Offering Period.

5.

I have received a copy of the complete Plan and its accompanying prospectus. I understand that my participation in

the Plan is in all respects subject to the terms of the Plan.

6.

7.

I understand that share purchases for me under the Plan will be issued in my name.

I  acknowledge  that,  regardless  of  any  action  taken  by  the  Company  or,  if  different,  the  Designated  Company  that

employs me (the “Employer”), the ultimate liability for

all  income  tax,  social  insurance,  payroll  tax,  fringe  benefits  tax,  payment  on  account  or  other  tax-related  items  related  to  my
participation in the Plan and legally applicable or deemed applicable to me (“Tax-Related Items”) is and remains my responsibility
and may exceed the amount, if any, actually withheld by the Company or the Employer. I further acknowledge that the Company
and/or Employer (i) make no representation or undertakings regarding the treatment of any Tax-Related Items in connection with
any aspect of my participation in the Plan, the subsequent sale of Shares acquired pursuant to such participation and the receipt of
any dividends, and (ii) do not commit to and are under no obligation to structure the terms of the option or any aspect of participation
in the Plan to reduce or eliminate my liability for Tax-Related Items or achieve any particular tax result. Further, if I am subject to
Tax-Related  Items  in  more  than  one  jurisdiction,  I  acknowledge  that  the  Company  and/or  the  Employer  (or  former  employer,  as
applicable) may be required to withhold or account for Tax-Related Items in more than one jurisdiction.

Prior to any relevant taxable or tax withholding event, as applicable, I agree to make adequate arrangements satisfactory to
the Company and/or Employer to satisfy all Tax-Related Items. In this regard, I authorize the Company and/or the Employer, or their
respective agents, at their discretion, to withhold any Tax-Related Items from any wages or other cash compensation payable to me
by the Company and/or the Employer. Alternatively, or in addition, if permissible under Applicable Laws, the Administrator, in its
sole discretion and pursuant to such procedures as it may specify from time to time, may permit or require me to satisfy such tax
withholding  obligation,  in  whole  or  in  part  (without  limitation)  by  (a)  paying  cash,  (b)  electing  to  have  the  Company  withhold
otherwise deliverable Shares having a Fair Market Value equal to the amount required to be withheld, (c) selling a number of Shares
otherwise deliverable to me through such means as the Company may determine in its sole discretion (whether through a broker or
otherwise) equal to the amount required to be withheld, or (d) any other method of withholding determined by the Company and to
the extent required by Applicable Laws or the Plan, approved by the Administrator.

Unless otherwise provided in the Plan or herein, the Company may withhold or account for Tax-Related Items by considering
statutory  or  other  withholding  rates,  including  minimum  or  maximum  rates  applicable  in  my  jurisdiction(s).  In  the  event  of  over-
withholding, I may receive a refund of any over-withheld amount in cash (with no entitlement to the equivalent in Shares), or if not
refunded, I may be able to seek a refund from the local tax authorities. In the event of under-withholding, I may be required to pay
any  additional  Tax-Related  Items  directly  to  the  applicable  tax  authority.  If  the  obligation  for  Tax-Related  Items  is  satisfied  by
withholding  in  Shares,  for  tax  purposes,  I  will  be  deemed  to  have  been  issued  the  full  number  of  Shares  subject  to  the  Plan,
notwithstanding that a number of the Shares is held back solely for the purpose of paying the Tax-Related Items.

If  I  fail  to  make  satisfactory  arrangements  to  satisfy  all  Tax-Related  Items  hereunder  prior  to  any  relevant  taxable  or  tax

withholding event, as applicable, I will permanently forfeit any right to receive Shares and participation in the Plan.

8.

By enrolling and participating in the Plan, I acknowledge, understand and agree that:

(a)

the  Plan  is  established  voluntarily  by  the  Company,  it  is  discretionary  in  nature  and  it  may  be  modified,

amended, suspended or terminated by the Company at any time, to the extent permitted by the Plan;

(b)

participation  in  the  Plan  is  voluntary  and  occasional,  and  does  not  create  any  contractual  or  other  right  to
receive  future  grants  of  options  to  purchase  Shares,  or  benefits  in  lieu  of  options  to  purchase  Shares,  even  if  options  to
purchase Shares have been granted in the past;

(c)
Company;

all  decisions  with  respect  to  future  options  to  purchase  Shares,  if  any,  will  be  at  the  sole  discretion  of  the

(d)

the grant of the option to purchase Shares under, and my participation in, the Plan shall not create a right to
employment or be interpreted as amending or forming an employment or service contract with the Company and shall not
interfere with the ability of the Employer to terminate my employment relationship (if any);

(e)

(f)

I am voluntarily participating in the Plan;

participation in the Plan, the Shares purchased under the Plan, and the income from and value of same, are not

intended to replace any pension rights or compensation;

(g)

participation in the Plan, the Shares purchased under the Plan, and the income from and value of same, are not
part  of  normal  or  expected  compensation  for  any  purposes,  including  but  not  limited  to  the  calculation  of  any  severance,
resignation, termination, redundancy, dismissal, end-of-service payments, holiday pay, bonuses, long-service awards, pension
or retirement or welfare benefits or similar payments;

(h)

unless otherwise agreed with the Company in writing, participation in the Plan, the Shares purchased under the
Plan, and the income from and value of same, are not granted as consideration for, or in connection with, the service I may
provide as a director of a Subsidiary;

(i)

the future value of the underlying Shares is unknown, indeterminable and cannot be predicted with certainty;

(j)
Purchase Price;

if  I  purchase  Shares  under  the  Plan,  the  value  of  such  Shares  may  increase  or  decrease,  even  below  the

(k)

no  claim  or  entitlement  to  compensation  or  damages  shall  arise  from  forfeiture  of  the  option  to  purchase
Shares resulting from my termination of employment (for any reason whatsoever, and whether or not later found to be invalid
or in breach of employment laws in the jurisdiction where I am employed or the terms of my employment agreement, if any);

(l)

in the event of termination  of my employment  (for any reason whatsoever,  whether or not later found to be
invalid or in breach of employment laws in the jurisdiction where I am employed or the terms of my employment agreement,
if  any),  my  right  to  participate  in  the  Plan  and  purchase  Shares,  if  any,  will  terminate  effective  as  of  the  date  I  cease  to
actively  provide  services  to  the  Company  or  a  Designated  Company  and  will  not  be  extended  by  any  notice  period  (e.g.,
employment  would  not  include  any  contractual  notice  or  any  period  of  “garden  leave”  or  similar  period  mandated  under
employment  laws  in  the  jurisdiction  where  I  am  employed  or  the  terms  of  my  employment  agreement,  if  any);  the
Administrator shall have exclusive discretion to determine when I am no longer actively providing services for purposes of
my  participation  in  the  Plan  (including  whether  I  may  still  be  considered  to  be  providing  services  while  I  am  on  leave  of
absence);

(m)

unless otherwise provided  in the  Plan or  by the  Company  in its  discretion, participation  in the  Plan and  the
benefits  evidenced  by  this  Agreement  do  not  create  any  entitlement  to  have  the  options  to  purchase  Shares  or  any  such
benefits transferred to, or assumed by, another company nor be exchanged, cashed out or substituted for, in connection with
any corporate transaction affecting the Shares; and

(n)

neither the Company nor the Employer shall be liable for any foreign exchange rate fluctuation between my
local  currency  and  the  United  States  Dollar  that  may  affect  the  value  of  any  amounts  due  to  me  under  the  Plan  or  the
subsequent sale of any Shares acquired upon purchase.

9.

(a)

Data Collection and Usage. The Company and the Employer may collect, process and use certain personal
information  about me, including,  but not limited to, my name, home address, telephone number, email address, date of
birth, social insurance number, passport or other identification number, salary, nationality, job title, any shares of stock
or  directorships  held  in  the  Company,  details  of  all  options  to  purchase  Shares  granted  under  the  Plan  or  any  other
entitlement to stock awarded, canceled, exercised, vested, unvested or outstanding in my favor (“Data”), for purposes of
implementing,  administering  and  managing  my  participation  in  the  Plan.  The  legal  basis,  where  required,  for  the
processing of Data is my consent.

(b)

Stock Plan Administration Service Providers.  The  Company  will  transfer  Data  to  E*TRADE  Financial
Services, Inc. and certain of its affiliated entities (the “E*TRADE”), an independent service provider based in the United
Stated which assists the Company with the implementation, administration and management of the Plan. The Company
may select a different service provider or additional service providers and share Data with such other provider serving in a
similar manner. I may be asked to agree on separate terms and data processing practices with the service provider, with
such agreement being a condition to the ability to participate in the Plan.

(c)

International  Data  Transfers.  The  Company  and  E*TRADE  are  based  in  the  U.S.  My  country  or
jurisdiction may have different data privacy laws and protections than the U.S. The Company’s legal basis for the transfer
of Data, where required, is my consent.

(d)

Data Retention. The Company will hold and use Data only as long as is necessary to implement, administer
and manage my participation in the Plan, or as required to comply with legal or regulatory obligations, including under
tax and security laws.

(e)

Voluntariness and Consequences of Consent Denial or Withdrawal. Participation in the Plan is voluntary
and I am providing the consents herein on a purely voluntary basis. If I do not consent, or if I later seek to revoke the
consent,  my  salary/compensation  from  or  service  relationship  will  not  be  affected;  the  only  consequence  of  refusing  or
withdrawing  consent  is  that  the  Company  would  not  be  able  to  offer  the  option  to  purchase  Shares  or  other  awards  or
administer or maintain such awards.

(f)

Data Subject Rights. I may have a number of rights under data privacy laws depending on my jurisdiction,
including the right to (i) request access to or copies of Data the Company processes, (ii) rectify incorrect Data, (iii) delete
Data,  (iv)  restrict  the  processing  of  Data,  (v)  restrict  the  portability  of  Data,  (vi)  lodge  complaints  with  competent
authorities in my jurisdiction, and/or (vii) receive a list with the names and addresses of any potential recipients of Data.
To receive clarification regarding these rights or to exercise these rights, I can contact the Company’s data privacy officer
at privacy@ringcentral.com.

10.

The Company is not providing any tax, legal or financial advice, nor is the Company making any recommendations
regarding my participation in the Plan, or my acquisition or sale of the Shares. I hereby agree to consult with my own personal tax,
legal and financial advisors regarding my participation in the Plan before taking any action related to the Plan.

11.

The Company may, in its sole discretion, decide to deliver any documents related to current or future participation in
the Plan by electronic means or request my consent to participate in the Plan by electronic means. I hereby consent to receive such
documents  by  electronic  delivery  and  agree  to  participate  in  the  Plan  through  any  on-line  or  electronic  system  established  and
maintained by the Company or a third party designated by the Company.

12.

In  the  event  that  any  provision  in  this  Agreement  will  be  held  invalid  or  unenforceable,  such  provision  will  be
severable from, and such invalidity or unenforceability will not be construed to have any effect on, the remaining provisions of this
Agreement.

13.

Notwithstanding  any  provisions  in  this  Agreement,  the  right  to  participate  in  the  Plan  shall  be  subject  to  any
additional  terms  and  conditions  the  Appendix  attached  hereto  for  my  country.  Moreover,  if  I  relocate  to  another  country,  the
additional terms and conditions for such country will apply to me, to the extent the Company determines that the application of such

terms and conditions is necessary or advisable for legal or administrative reasons. The Appendix constitutes part of this Agreement.

14.

The  Company  reserves  the  right  to  impose  other  requirements  on  my  participation  in  the  Plan  and  on  any  Shares
acquired under the Plan, to the extent the Company determines it is necessary or advisable for legal or administrative reasons, and to
require me to sign any additional agreements or undertakings that may be necessary to accomplish the foregoing.

15.

If  at  any  time  the  Company  will  determine,  in  its  discretion,  that  the  listing,  registration,  qualification  or  rule
compliance of the Shares upon any securities exchange or under Applicable Laws or the consent or approval of any governmental
regulatory authority is necessary or desirable as a condition to the issuance of Shares to me hereunder, such issuance will not occur
unless and until such listing, registration, qualification, rule compliance, consent or approval will have been completed, effected or
obtained free of any conditions not acceptable to the Company. Where the Company determines that the delivery of any Shares will
violate any Applicable Laws, the Company will defer delivery until the earliest date at which the Company reasonably anticipates
that  the  delivery  of  Shares  will  no  longer  cause  such  violation.  The  Company  will  make  all  reasonable  efforts  to  meet  the
requirements  of  any  such  Applicable  Laws  and  to  obtain  any  such  consent  or  approval  of  any  such  governmental  authority  or
securities exchange.

16.

This  Agreement  will  be  governed  by  the  laws  of  Delaware  without  giving  effect  to  the  conflict  of  law  principles
thereof. For purposes of litigating any dispute that arises under participation in the Plan or this Agreement, the parties hereby submit
to and consent to the exclusive jurisdiction of the State of California, and agree that such litigation will be conducted exclusively in
the courts of San Mateo County, California, or the federal courts for the United States for the Northern District of California, and no
other courts, where the option to purchase Shares is offered and/or to be performed.

17.

I acknowledge  that a waiver by the Company of breach of any provision of this Agreement shall not operate or be

construed as a waiver of any other provision of this Agreement, or of any subsequent breach by me or any other Participant.

18.

I  hereby  agree  to  be  bound  by  the  terms  of  the  Plan.  The  effectiveness  of  this  Agreement  is  dependent  upon  my

eligibility to participate in the Plan.

I UNDERSTAND THAT THIS AGREEMENT WILL REMAIN IN EFFECT THROUGHOUT SUCCESSIVE OFFERING

PERIODS UNLESS I CEASE TO BE AN ELIGIBLE EMPLOYEE OR WITHDRAW FROM THE PLAN; PROVIDED,
HOWEVER, THAT PARTICIPATION IN ANY SUBSEQUENT OFFERING PERIOD WILL BE GOVERNED BY THE TERMS
AND CONDITIONS OF THE PLAN AND THIS AGREEMENT IN EFFECT AT THE BEGINNING OF SUCH OFFERING
PERIOD, SUBJECT TO MY RIGHT TO WITHDRAW.

APPENDIX

ADDITIONAL TERMS AND CONDITIONS

FOR NON-U.S. PARTICIPANTS

Capitalized terms used but not defined in this Appendix will have the meanings set forth in the Plan and/or the Global Subscription
Agreement.

Terms and Conditions

This Appendix, which is part of the Agreement, includes additional terms and conditions applicable to me if I work and/or reside
outside the United States or am otherwise subject to the laws of a country other than the United States. If I am a citizen or resident of
a country other than the one in which I am currently working and/or residing (or if I am considered as such for local law purposes),
or if I transfer employment or residence to another country after enrolling in the Plan, I acknowledge and agree that the Company, in
its discretion, will determine the extent to which the terms and conditions herein will be applicable to me.

Notifications

This Appendix also includes information regarding securities laws, exchange controls and certain other issues of which I should be
aware with respect to my participation in the Plan. The information is based on the securities, exchange control and other laws in
effect in the respective countries as of January 2021. Such laws are often complex and change frequently. As a result, the Company
strongly recommends that I do not rely on the information in this Appendix as the only source of information relating to the
consequences of my participation in the Plan, because the information included herein may be out of date at the time that I acquire
Shares under the Plan or subsequently sell such Shares.

In addition, the information contained herein is general in nature and may not apply to my particular situation and the Company is
not in a position to assure me of any particular result. Accordingly, I should seek appropriate professional advice as to how the
relevant laws in my country may apply to my individual situation.

Finally, if I am a citizen or resident of a country other than the one in which I currently am working and/or residing (or if I am
considered as such for local law purposes), or if I transfer employment and/or residency to another country after options to purchase
Shares have been granted to me under the Plan, the information contained herein may not be applicable to me.

Terms and Conditions

ALL EMPLOYEES OUTSIDE THE U.S.

1. Language. I acknowledge that I am sufficiently proficient in English, or have consulted with an advisor who is proficient in
the English language, so as to enable me to understand the terms and conditions in this Agreement and the Plan. If I have received
this Agreement  or any  other  document  related  to the Plan  translated  into a language  other  than English  and if the meaning  of the
translated version is different than the English version, the English version will control.

2.

Insider-Trading  /  Market-Abuse  Laws.  I  acknowledge  that  I  may  be  subject  to  insider-trading  restrictions  and/or  market-
abuse laws in applicable jurisdictions, including but not limited to the United States and my country, which may affect my ability to
purchase  or  sell  Shares  acquired  under  the  Plan  during  such  times  as  I  am  considered  to  have  “inside  information”  regarding  the
Company  (as  defined  by  the  laws  or  regulations  in  my  country).  Local  insider-trading  laws  and  regulations  may  prohibit  the
cancellation  or  amendment  of  orders  I  place  before  possessing  inside  information.  Furthermore,  I  could  be  prohibited  from  (i)
disclosing the inside information to any third party (other than on a “need to know” basis) and (ii) “tipping” third parties or causing
them otherwise to buy or sell securities. Third parties include fellow employees. Any restrictions under these laws or regulations are
separate from and in addition to any restrictions that may be imposed under any applicable Company insider-trading policy. I am
responsible  for  complying  with  any  applicable  restrictions,  and  I  should  speak  to  my  personal  legal  advisor  for  further  details
regarding any applicable insider-trading and/or market-abuse laws in applicable jurisdictions.

3. Foreign Asset/Account Reporting and Exchange Control Requirements. I acknowledge that there may be certain foreign asset
and/or account reporting and/or exchange control requirements which may affect my ability to acquire or hold the Shares acquired
under the Plan or cash received from participating in the Plan (including from any dividends paid on the Shares acquired under the
Plan) in a brokerage or bank account outside my country. I may be required to report such accounts, assets or transactions to the tax
or  other  authorities  in  my  country.  I  also  may  be  required  to  repatriate  sale  proceeds  or  other  funds  received  as  a  result  of  my
participation in the Plan to my country through a designated bank or broker and/or within a certain time after receipt. I acknowledge
that it is my responsibility to be compliant with such regulations, and I should consult my personal advisor on this matter.

Terms and Conditions

AUSTRALIA

Australia Offer Document. The Company is pleased to provide this offer to participate in the Plan. This offer sets out information
regarding the grant of options to purchase Shares to Australian resident employees. This information is provided by the Company to
ensure

compliance of the Plan with Australian Securities and Investments Commission (“ASIC”) Class Order 14/1000 and relevant
provisions of the Corporations Act 2001.

In addition to the information set out in this Agreement (including this Appendix), the Company is also providing with copies of the
following documents:

(a) the Plan;

(b) the Plan prospectus; and

(c) Employee Information Supplement (collectively, the “Additional Documents”).

The Additional Documents provide further information to help me make an informed investment decision about participating in the
Plan. Neither the Plan nor the Plan prospectus is a prospectus for the purposes of the Corporations Act 2001.

I should not rely upon any oral statements made in relation to this offer. I understand that I I should rely only upon the statements
contained in this Agreement (including this Appendix), and the Additional Documents when considering participation in the Plan.

Notifications

Tax Information. The Plan is a plan to which Subdivision 83A-C of the Income Tax Assessment Act 1997 (Cth) applies (subject to
conditions in the Act).

Securities Law Information. Investment in Shares involves a degree of risk. Eligible employees who elect to participate in the Plan
should monitor their participation and consider all risk factors relevant to the acquisition of Shares under the Plan as set forth below
and in the Additional Documents.

The information herein is general information only. It is not advice or information that takes into account my objectives, financial
situation and needs. I understand that I should consider obtaining my own financial product advice from a person who is licensed by
ASIC to give such advice.

Additional Risk Factors for Australian Residents. I understand that I should have regard to risk factors relevant to investment in
securities generally and, in particular, to holding Shares. For example, the price at which an individual Share is quoted on the New
York Stock Exchange (“NYSE”) may increase or decrease due to a number of factors. There is no guarantee that the price of a Share
will increase. Factors that may affect the price of an individual Share include fluctuations in the domestic and international market
for listed stocks, general economic conditions, including interest rates, inflation rates, commodity and oil prices, changes to
government fiscal, monetary or regulatory policies, legislation or regulation, the nature of the markets in which the Company
operates and general operational and business risks.

More information about potential factors that could affect the Company’s business and financial results will be included in the
Company’s most recent Annual Report on Form 10-K and the

Company’s Quarterly Report on Form 10-Q. Copies of these reports are available at www.sec.gov, on the Company’s investor’s
page at ir.ringcentral.com, and upon request to the Company.

In addition, I understand that I should be aware that the Australian dollar (“AUD”) value of any Shares acquired under the Plan will
be affected by the USD/AUD exchange rate. Participation in the Plan involves certain risks related to fluctuations in this rate of
exchange.

Common Stock in a U.S. Corporation. Common stock of a U.S. corporation is analogous to ordinary shares of an Australian
corporation. Each holder of a Share is entitled to one vote. Dividends may be paid on the Shares out of any funds of the Company
legally available for dividends at the discretion of the Board. Further, Shares are not liable to any further calls for payment of capital
or for other assessment by the Company and have no sinking fund provisions, pre-emptive rights, conversion rights or redemption
provisions.

Ascertaining the Market Price of Shares. I understand that I may ascertain the current market price of an individual Share as traded
on the NYSE under the symbol “RNG” at www.nyse.com/quote/XNYS:RNG. The AUD equivalent of that price can be obtained at
www.rba.gov.au/statistics/frequency/exchange-rates.html. Please note that this is not a prediction of what the market price of the
Shares will be on any applicable vesting date or when Shares are issued to me (or at any other time), or of the applicable exchange
rate at such time.

Terms and Conditions

CANADA

Termination of Employment. The following provisions replace Section 8(l) of the Global Subscription Agreement:

In the event of termination of my employment (for any reason whatsoever, whether or not later found to be invalid or in breach of
employment laws in the jurisdiction where I am employed or the terms of my employment agreement, if any), my right to participate
in the Plan and purchase Shares, if any, will terminate effective as of the date that is the earlier of (i) the date my employment
relationship terminates, and (ii) the date I receive notice of termination of employment. In either case, the date shall exclude any
period during which notice, pay in lieu of notice or related payments or damages are provided or required to be provided under
applicable employment standards legislation. For greater certainty, I will not be entitled to any pro-rated option to purchase Shares
under the Plan for that portion of time before the date on which my participation terminates, nor will I be entitled to any
compensation for lost ability to purchase Shares.

Notwithstanding the foregoing, if applicable employment standards legislation explicitly requires continued participation in the Plan
during a statutory notice period, my option to purchase Shares under the Plan, if any, will terminate effective as of the last day of my
minimum statutory notice period, but I will not be entitled to a pro-rata option to purchase Shares if the Exercise Date falls

after the end of the my statutory notice period, nor will I be entitled to any compensation for lost ability to purchase Shares.

The following provisions apply if I reside in Quebec:

Language Consent. The parties acknowledge that it is their express wish that this Agreement, as well as all documents, notices and
legal proceedings entered into, given or instituted pursuant hereto or relating directly or indirectly hereto, be drawn up in English.

Consentement Relatif à la Langue. Les parties reconnaissent avoir exigé la rédaction en anglais de cette convention, ainsi que de
tous documents, avis et procédures judiciaires, exécutés, donnés ou intentés en vertu de, ou liés directement ou indirectement à, la
présente convention.

Data Privacy. The following provisions supplement Section 9 of the Global Subscription Agreement:

I hereby authorize the Company and the Company’s representatives to discuss with and obtain all relevant information from all
personnel, professional or not, involved in the administration and operation of the Plan. I further authorize the Company, the
Employer (or any other Parent or Subsidiary) and the Administrator to disclose and discuss the Plan with their advisors. I further
authorize the Company, the Employer (or any other Parent or Subsidiary) to record such information and to keep such information in
my employee file.

Notifications

Securities Law Information. I am permitted to sell Shares acquired under the Plan through the designated broker appointed under the
Plan, if any, provided the sale of the Shares takes place outside of Canada through the facilities of a stock exchange on which the
Shares are listed (i.e., the New York Stock Exchange).

CHINA

The following provisions apply if I am subject to exchange control restrictions imposed by the State Administration of Foreign
Exchange (“SAFE”), as determined by the Administrator in its sole discretion:

Terms and Conditions

Purchase of Shares. Notwithstanding anything in the Plan or this Agreement to the contrary, I understand that I will not be permitted
to exercise the option to purchase Shares granted to me under the Plan or purchase any Shares under the Plan unless the Company
determines that all necessary exchange control or other approvals with respect to the options granted under the Plan have been
obtained from SAFE or its local counterpart. Further, the Company is under no obligation to allow me to exercise the option and/or
purchase Shares if the Company’s SAFE approval becomes invalid or ceases to be in effect prior to any applicable Exercise Date
under the Plan, in which case any options granted to me under the Plan may be cancelled, without any liability to the Company or
any Parent or Subsidiary, and any payroll deductions that I have

contributed towards the purchase of Shares under the Plan will be refunded to me, without interest.

Due to local regulatory requirements, the Company reserves the right to force the sale of any Shares issued upon purchase. The sale
may occur (i) immediately upon issuance, (ii) following termination, (iii) following transfer to the Company, a Parent or Subsidiary
outside of China, or (iv) within any other time frame as the Company determines to be necessary or advisable for legal or
administrative reasons. I am required to maintain any Shares acquired under the Plan in an account at a broker designated by the
Company (“Designated Account”) and any Shares deposited into the Designated Account cannot be transferred out of the
Designated Account unless and until they are sold.

In order to facilitate the foregoing, the Company is authorized to instruct its designated broker to assist with the sale of the Shares
(on my behalf pursuant to this authorization without further consent) and I expressly authorize the Company’s designated broker to
complete the sale of such Shares. I acknowledge that the Company’s designated broker is under no obligation to arrange for the sale
of the Shares at any particular price. Upon the sale of the Shares, the Company will pay to me the cash proceeds from the sale, less
any brokerage fees or commissions and subject to any obligation to satisfy Tax-Related Items. If the Shares acquired under the Plan
are sold, the repatriation requirements described below shall apply.

Exchange Control Requirement. Pursuant to exchange control requirements in China, I will be required to immediately repatriate to
China any cash proceeds from the sale of the Shares that I acquired under the Plan or the receipt of any dividends paid on such
Shares. I understand that, under Applicable Laws, such repatriation of the cash proceeds may need to be effectuated through a
special exchange control account established by the Company or a Parent or Subsidiary in China, and I hereby consent and agree that
any proceeds from the sale of Shares or the receipt of dividends may be transferred to such special account prior to being delivered
to me. I also understand that the Company will deliver the proceeds to me as soon as possible, but that there may be delays in
distributing the funds to me due to exchange control requirements. I understand that the proceeds may be paid to me in U.S. dollars
or in local currency, at the Company’s discretion. If the proceeds are paid to me in U.S. dollars, I will be required to set up a U.S.
dollar bank account in China so that the proceeds may be deposited into this account. If the proceeds are paid to me in local
currency, the Company is under no obligation to secure any particular exchange conversion rate and the Company may face delays
in converting the proceeds to local currency due to exchange control restrictions.

Finally, I agree to comply with any other requirements that may be imposed by the Company in the future in order to facilitate
compliance with exchange control requirements in China.

the same defined meanings in this Global Restricted Stock Unit Agreement (the “Award Agreement”), which includes the Notice of
Restricted  Stock  Unit  Grant  (the  “Notice  of  Grant”),  Terms  and  Conditions  of  Restricted  Stock  Unit  Grant,  attached  hereto  as
Exhibit A, and Country-Specific Terms and Conditions of Restricted Stock Unit Grant, attached hereto as Exhibit B.

NOTICE OF RESTRICTED STOCK UNIT GRANT

Participant Name:

Award Agreement, as follows:

Date of Grant
Grant Number
Vesting Commencement Date
Number of Restricted Stock Units

Vesting Schedule:

Subject  to  any  acceleration  provisions  contained  in  the  Plan  or  set  forth  below,  the  Restricted  Stock  Units  will  vest  in

accordance with the following schedule:

RSU Vesting Date

Number of RSUs Vesting

In each case, subject to Participant continuing to be a Service Provider through each such date, “RSU Vesting Date” means

each of February 20, May 20, August 20 and November 20.

Notwithstanding  the  foregoing,  the  vesting  of  the  Restricted  Stock  Units  shall  be  subject  to  any  vesting  acceleration
provisions applicable to the Restricted Stock Units contained in the Plan and/or any change in control severance agreement or other
agreement  that,  prior  to  and  effective  as  of  the  date  of  this  Award  Agreement,  has  been  entered  into  between  Participant  and  the
Company  or  any  Parent  or  Subsidiary  (such  agreement,  a  “Separate  Agreement”)  to  the  extent  not  otherwise  duplicative  of  the
vesting terms described above (by way of example, if a Separate Agreement provides for different acceleration of vesting provisions
for all of Participant’s restricted stock units upon a termination of Participant as a Service Provider for “good reason” that is defined
differently, and Participant’s status as a Service Provider terminates in a manner that would trigger “good reason” under the Separate
Agreement but not

under this Award Agreement, Participant would remain entitled to the acceleration of vesting under the Separate Agreement).

In the event Participant ceases to be a Service Provider for any or no reason before Participant vests in the Restricted Stock

Units, the Restricted Stock Units and Participant’s right to acquire any Shares hereunder will immediately terminate.

By  Participant’s  signature  and  the  signature  of  the  representative  of  RingCentral,  Inc.  (the  “Company”)  below,  Participant
and the Company agree that this Award of Restricted Stock Units is granted under and governed by the terms and conditions of the

part of this document. Participant has reviewed the Plan and this Award Agreement in their entirety, has had an opportunity to obtain
the  advice  of  counsel  prior  to  executing  this  Award  Agreement  and  fully  understands  all  provisions  of  the  Plan  and  Award
Agreement. Participant hereby agrees to accept as binding, conclusive and final all decisions or interpretations of the Administrator
upon any questions relating to the Plan and Award Agreement. Participant further agrees to notify the Company upon any change in
the residence address indicated above.

Unit Grant, and consents to the collection, processing and use of Data by the Company and the transfer of Data to the recipients mentioned
therein, including recipients located in countries which do not provide an adequate level of protection from a European data protection law
perspective,  for  the  purposes  described  therein. Participant  understands  that  providing  his  or  her  signature  below  is  a  condition  of
receiving this grant of Restricted Stock Units and that the Company may forfeit the Restricted Stock Units if a signature is not obtained.

PARTICIPANT: ____________________

TERMS AND CONDITIONS OF RESTRICTED STOCK UNIT GRANT

EXHIBIT A

1.

Grant. The Company hereby grants to the individual named in the Notice of Grant (the “Participant”) under the Plan
an Award of Restricted Stock Units, subject to all of the terms and conditions in this Award Agreement, the Plan, and the Separate
Agreement (as applicable), which are incorporated herein by reference. Subject to Section 19(c) of the Plan, in the event of a conflict
between the terms and conditions of the Plan and the terms and conditions of this Award Agreement, the terms and conditions of the
Plan will prevail.

2.

Company’s Obligation to Pay. Each Restricted Stock Unit represents the right to receive a Share on the date it vests.
Unless and until the Restricted Stock Units will have vested in the manner set forth in Sections 3 or 4, Participant will have no right
to payment of any such Restricted Stock Units. Prior to actual payment of any vested Restricted Stock Units, such Restricted Stock
Units will represent an unsecured obligation of the Company, payable (if at all) only from the general assets of the Company. Any
Restricted Stock Units that vest in accordance with Sections 3 or 4 will be paid to Participant (or in the event of Participant’s death,
to his or her estate) in whole Shares, subject to Participant satisfying any obligations for Tax-Related Items (as defined in Section 7).
Subject to the provisions of Section 4, such vested Restricted Stock Units shall be paid in whole Shares as soon as practicable after
vesting, but in each such case within the period sixty (60) days following the vesting date. In no event will Participant be permitted,
directly or indirectly, to specify the taxable year of the payment of any Restricted Stock Units payable under this Award Agreement.

3.

Vesting Schedule. Except as provided in Section 4, and subject to Section 5, the Restricted Stock Units awarded by
this Award Agreement will vest in accordance with the vesting provisions set forth in the Notice of Grant. Restricted Stock Units
scheduled to vest on a certain date or upon the occurrence of a certain condition will not vest in Participant in accordance with any of
the provisions of this Award Agreement, unless Participant will have been continuously a Service Provider from the Date of Grant
until the date such vesting occurs.

4.

Administrator  Discretion.  The  Administrator,  in  its  discretion,  may  accelerate  the  vesting  of  the  balance,  or  some
lesser portion of the balance, of the unvested Restricted Stock Units at any time, subject to the terms of the Plan. If so accelerated,
such Restricted Stock Units will be considered as having vested as of the date specified by the Administrator. The payment of Shares
vesting pursuant to this Section 4 shall in all cases be paid at a time or in a manner that is exempt from, or complies with, Section
409A.

Notwithstanding anything in the Plan or this Award Agreement to the contrary, if the vesting of the balance, or some lesser
portion of the balance, of the Restricted Stock Units is accelerated in connection with Participant’s termination as a Service Provider
(provided that such termination is a “separation from service” within the meaning of Section 409A, as determined by the Company),
other  than  due  to  death,  and  if  (x)  Participant  is  a  “specified  employee”  within  the  meaning  of  Section  409A  at  the  time  of  such
termination as a Service

Provider and (y) the payment of such accelerated Restricted Stock Units will result in the imposition of additional tax under Section
409A if paid to Participant on or within the six (6) month period following Participant’s termination as a Service Provider, then the
payment of such accelerated Restricted Stock Units will not be made until the date six (6) months and one (1) day following the date
of Participant’s termination as a Service Provider, unless Participant dies following his or her termination as a Service Provider, in
which case the Restricted Stock Units will be paid in Shares to Participant’s estate as soon as practicable following his or her death.
It  is  the  intent  of  this  Award  Agreement  that  it  and  all  payments  and  benefits  hereunder  be  exempt  from,  or  comply  with,  the
requirements of Section 409A so that none of the Restricted Stock Units provided under this Award Agreement or Shares issuable
thereunder will be subject to the additional tax imposed under Section 409A, and any ambiguities herein will be interpreted to be so
exempt or so comply. Each payment payable under this Award Agreement is intended to constitute a separate payment for purposes
of Treasury Regulation Section 1.409A-2(b)(2). For purposes of this Award Agreement, “Section 409A” means Section 409A of the
Code, and any final Treasury Regulations and U.S. Internal Revenue Service guidance thereunder, as each may be amended from
time to time.

5.

Forfeiture upon Termination of Status as a Service Provider. Notwithstanding any contrary provision of this Award
Agreement,  the balance  of the Restricted  Stock Units that have not vested as of the time of Participant’s  termination  as a Service
Provider  for  any  or  no  reason,  and  Participant’s  right  to  acquire  any  Shares  hereunder,  will  immediately  terminate.  The  date  of
Participant’s termination as a Service Provider is detailed in Section 10(f).

6.

Death  of  Participant.  Any  distribution  or  delivery  to  be  made  to  Participant  under  this  Award  Agreement  will,  if
Participant  is  then  deceased,  be  made  to  Participant’s  designated  beneficiary,  or  if  no  beneficiary  survives  Participant,  the
administrator or executor of Participant’s estate. Any such transferee must furnish the Company with (a) written notice of his or her
status as transferee, and (b) evidence satisfactory to the Company to establish the validity of the transfer and compliance with any
laws or regulations pertaining to said transfer.

7.

Responsibility  for  Taxes.  Participant  acknowledges  that,  regardless  of  any  action  taken  by  the  Company  or,  if
different, the Subsidiary to which Participant provides services (the “Service Recipient”), the ultimate liability for all income tax,
social insurance, payroll tax, fringe benefits tax, payment on account or other tax-related items related to Participant’s participation
in  the  Plan  and  legally  applicable  or  deemed  applicable  to  Participant  (“Tax-Related  Items”)  is  and  remains  Participant’s
responsibility  and may exceed  the  amount,  if any,  actually  withheld  by the Company  or the  Service  Recipient.  Participant  further
acknowledges that the Company and/or Service Recipient (i) make no representation or undertakings regarding the treatment of any
Tax-Related Items in connection with any aspect of the Restricted Stock Units or the underlying Shares, including but not limited to
the grant, vesting or settlement of the Restricted Stock Units, the subsequent sale of Shares acquired pursuant to such settlement and
the receipt of any dividends, and (ii) do not commit to and are under no obligation to structure the terms of the grant or any aspect of
the  Restricted Stock  Units to  reduce or  eliminate Participant’s liability  for Tax-Related  Items or  achieve any  particular tax  result.
Further,  if  Participant  is  subject  to  Tax-Related  Items  in  more  than  one  jurisdiction,  Participant  acknowledges  that  the  Company
and/or

the Service Recipient (or former service recipient, as applicable) may be required to withhold or account for Tax-Related Items in
more than one jurisdiction.

Prior  to  any  relevant  taxable  or  tax  withholding  event,  as  applicable,  Participant  agrees  to  make  adequate  arrangements
satisfactory  to  the  Company  and/or  Service  Recipient  to  satisfy  all  Tax-Related  Items.  In  this  regard,  Participant  authorizes  the
Company  and/or  the  Service  Recipient,  or  their  respective  agents,  to  sell  on  Participant’s  behalf  a  number  of  Shares  from  those
Shares otherwise deliverable to Participant, either through a voluntary sale or through a mandatory sale arranged by the Company
(on  Participant’s  behalf  pursuant  to  this  authorization  without  further  consent),  as  the  Company  determines  to  be  appropriate  to
generate cash proceeds sufficient to satisfy any applicable withholding obligations or rights for Tax-Related Items. Alternatively, or
in addition, if permissible under applicable local law, the Company, in its sole discretion and pursuant to such procedures as it may
specify  from  time  to  time,  may  satisfy  such  tax  withholding  obligation,  in  whole  or  in  part  (without  limitation)  by  (a)  requiring
Participant to make a payment in a form acceptable to the Company, (b) withholding otherwise deliverable Shares upon settlement
having  a  fair  market  value  equal  to  the  minimum  amount  required  to  be  withheld,  (c)  withholding  any  wages  or  other  cash
compensation payable to Participant by the Company and/or the Service Recipient, (d) if Participant is a U.S. employee, delivering
to the Company already vested and owned Shares, or (e) any other method of withholding determined by the Company and to the
extent required by applicable law or the Plan, approved by the Administrator. Notwithstanding the above, if Participant is a Section
16 officer of the Company under the Exchange Act, then the obligation for Tax-Related Items will be satisfied by method (b) above,
unless otherwise provided by the Administrator (as constituted to satisfy Rule 16b-3 of the Exchange Act) prior to the withholding
event.

Unless otherwise provided in the Plan or herein, the Company may withhold or account for Tax-Related Items by considering
statutory  or  other  withholding  rates  applicable  in  Participant’s  jurisdiction(s).  In  the  event  of  over-withholding,  Participant  may
receive a refund of any over-withheld amount in cash (with no entitlement to the equivalent in Shares), or if not refunded, Participant
may be able to seek a refund from the local tax authorities. In the event of under-withholding, Participant may be required to pay any
additional  Tax-Related  Items  directly  to  the  applicable  tax  authority.  If  the  obligation  for  Tax-Related  Items  is  satisfied  by
withholding  in  Shares,  for  tax  purposes,  Participant  will  be  deemed  to  have  been  issued  the  full  number  of  Shares  subject  to  the
vested Restricted Stock Units, notwithstanding that a number of the Shares is held back solely for the purpose of paying the Tax-
Related Items.

If Participant fails to make satisfactory arrangements to satisfy all Tax-Related Items hereunder prior to any relevant taxable
or  tax  withholding  event,  as  applicable,  Participant  will  permanently  forfeit  such  Restricted  Stock  Units  and  any  right  to  receive
Shares thereunder and the Restricted Stock Units will be returned to the Company at no cost to the Company.

8.

Rights as Stockholder. Neither Participant nor any person claiming under or through Participant will have any of the
rights  or  privileges  of  a  stockholder  of  the  Company  in  respect  of  any  Shares  deliverable  hereunder  unless  and  until  certificates
representing such Shares will have been issued, recorded on the records of the Company or its transfer agents or registrars,

and delivered to Participant. After such issuance, recordation and delivery, Participant will have all the rights of a stockholder of the
Company with respect to voting such Shares and receipt of dividends and distributions on such Shares.

9.

No  Guarantee  of  Continued  Service.  PARTICIPANT  ACKNOWLEDGES  AND  AGREES  THAT  THE  VESTING
OF  THE  RESTRICTED  STOCK  UNITS  PURSUANT  TO  THE  VESTING  SCHEDULE  HEREOF  IS  EARNED  ONLY  BY
CONTINUING AS A SERVICE PROVIDER OF THE COMPANY OR A PARENT OR SUBSIDIARY, AND NOT THROUGH
THE  ACT  OF  BEING  HIRED,  BEING  GRANTED  THIS  AWARD  OF  RESTRICTED  STOCK  UNITS  OR  ACQUIRING
SHARES HEREUNDER. PARTICIPANT FURTHER ACKNOWLEDGES AND AGREES THAT THIS AWARD AGREEMENT,
THE TRANSACTIONS CONTEMPLATED HEREUNDER AND THE VESTING SCHEDULE SET FORTH HEREIN DO NOT
CONSTITUTE AN EXPRESS OR IMPLIED PROMISE OF CONTINUED ENGAGEMENT AS A SERVICE PROVIDER FOR
THE  VESTING  PERIOD,  FOR  ANY  PERIOD,  OR  AT  ALL,  AND  WILL  NOT  INTERFERE  IN  ANY  WAY  WITH
PARTICIPANT’S  RIGHT  OR  THE  RIGHT  OF  THE  COMPANY  OR  THE  SERVICE  RECIPIENT  TO  TERMINATE
PARTICIPANT’S RELATIONSHIP AS A SERVICE PROVIDER AT ANY TIME, WITH OR WITHOUT CAUSE.

10.

Nature of Grant. In accepting the grant, Participant acknowledges, understands and agrees that:

a.

the  Plan  is  established  voluntarily  by  the  Company,  it  is  discretionary  in  nature  and  it  may  be  modified,  amended,

suspended or terminated by the Company at any time, to the extent permitted by the Plan;

b.

the grant of the Restricted Stock Units is voluntary and occasional, and does not create any contractual or other right
to receive future grants of Restricted Stock Units, or benefits in lieu of Restricted Stock Units, even if Restricted Stock Units have
been granted in the past;

c.
Company;

d.

e.

all decisions with respect to future Restricted Stock Units or other grants, if any, will be at the sole discretion of the

f.

the  Restricted  Stock  Units  and  the  Shares  subject  to  the  Restricted  Stock  Units,  and  the  income  from  and  value  of
same, are not part of normal or expected compensation for any purpose, including but not limited to the calculation of any severance,
resignation,  termination,  redundancy,  dismissal,  end-of-service  payments,  bonuses,  holiday  pay,  long-service  awards,  pension  or
retirement or welfare benefits or similar payments;

g.

unless  otherwise  agreed  with  the  Company  in  writing,  the  Restricted  Stock  Units  and  the  Shares  subject  to  the
Restricted  Stock  Units,  and  the  income  from  and  value  of  same,  are  not  granted  as  consideration  for,  or  in  connection  with,  the
service Participant may provide as a director of a Subsidiary;

h.

the future value of the underlying Shares is unknown, indeterminable and cannot be predicted with certainty;

i.

no claim or entitlement to compensation or damages shall arise from forfeiture of the Restricted Stock Units resulting
from the termination of Participant’s status as a Service Provider (for any reason whatsoever whether or not later found to be invalid
or  in  breach  of  employment  laws  in  the  jurisdiction  where  Participant  is  a  Service  Provider  or  the  terms  of  Participant’s  service
agreement, if any);

j.

for purposes of the Restricted Stock Units, Participant’s status as a Service Provider will be considered terminated as
of the date Participant is no longer actively providing services to the Company or any Parent or Subsidiary (regardless of the reason
for  such  termination  and  whether  or  not  later  to  be  found  invalid  or  in  breach  of  employment  laws  in  the  jurisdiction  where
Participant  is  a  Service  Provider  or  the  terms  of  Participant’s  employment  or  service  agreement,  if  any),  and  unless  otherwise
expressly provided in this Award Agreement or determined by the Administrator, Participant’s right to vest in the Restricted Stock
Units under the Plan, if any, will terminate as of such date and will not be extended by any notice period (e.g., Participant’s period of
service  would  not  include  any  contractual  notice  period  or  any  period  of  “garden  leave”  or  similar  period  mandated  under
employment  laws  in  the  jurisdiction  where  Participant  is  a  Service  Provider  or  the  terms  of  Participant’s  employment  or  service
agreement,  if  any);  the  Administrator  shall  have  the  exclusive  discretion  to  determine  when  Participant  is  no  longer  actively
providing services for purposes of the Restricted Stock Units (including whether Participant may still be considered to be providing
services while on a leave of absence);

k.

unless otherwise provided in the Plan or by the Company in its discretion, the Restricted Stock Units and the benefits
evidenced by this Award Agreement do not create any entitlement to have the Restricted Stock Units or any such benefits transferred
to, or assumed by, another company nor be exchanged, cashed out or substituted for, in connection with any corporate transaction
affecting the Shares; and

l.

none of the Company, the Service Recipient, or any Parent or Subsidiary shall be liable for any foreign exchange rate
fluctuation between Participant’s local currency and the United States dollar that may affect the value of the Restricted Stock Units
or of any amounts due to Participant pursuant to the settlement of the Restricted Stock Units or the subsequent sale of any Shares
acquired upon settlement.

11.

No Advice Regarding  Grant. The Company is not providing any tax, legal or financial advice, nor is the Company

making any recommendations regarding Participant’s

participation in the Plan, or Participant’s acquisition or sale of the underlying Shares. Participant agrees to consult with his or her
own personal tax, legal and financial advisors regarding his or her participation in the Plan before taking any action related to the
Plan.

12.

Data Privacy.

(a)

Data Collection and Usage. The Company and the Service Recipient may collect, process and use certain personal
information about Participant, including, but not limited to, Participant’s name, home address, telephone number, email address,
date of birth, social insurance number, passport or other identification number, salary, nationality, job title, any shares of stock
or  directorships  held  in  the  Company,  details  of  all  Restricted  Stock  Units  granted  under  the  Plan  or  any  other  entitlement  to
stock  awarded,  canceled,  exercised,  vested,  unvested  or  outstanding  in  Participant’s  favor  (“Data”),  for  purposes  of
implementing,  administering  and  managing  Participant’s  participation  in  the  Plan.  The  legal  basis,  where  required,  for  the
processing of Data is Participant’s consent.

(b)

Stock Plan Administration Service Providers. The Company will transfer Data to E*TRADE Financial Services,
Inc.  and  certain  of  its  affiliated  entities  (the  “E*TRADE”),  an  independent  service  provider  based  in  the  United  Stated  which
assists the Company with the implementation, administration and management of the Plan. The Company may select a different
service provider or additional service providers and share Data with such other provider serving in a similar manner. Participant
may be asked to agree on separate terms and data processing practices with the service provider, with such agreement being a
condition to the ability to participate in the Plan.

(c)

International  Data  Transfers.  The  Company  and  E*TRADE  are  based  in  the  U.S.  Participant’s  country  or
jurisdiction  may  have  different  data  privacy  laws  and  protections  than  the  U.S.  The  Company’s  legal  basis  for  the  transfer  of
Data, where required, is Participant’s consent.

(d)

Data Retention. The Company will hold and use Data only as long as is necessary to implement, administer and
manage Participant’s participation in the Plan, or as required to comply with legal or regulatory obligations, including under tax
and security laws.

(e)

Voluntariness and Consequences of Consent Denial or Withdrawal. Participation in the Plan is voluntary and
Participant is providing the consents herein on a purely voluntary basis. If Participant does not consent, or if Participant later
seeks  to  revoke  the  consent,  Participant’s  salary/compensation  from  or  service  relationship  will  not  be  affected;  the  only
consequence of refusing or withdrawing  consent is that the Company would not be able to grant the Restricted Stock Units or
other awards or administer or maintain such awards.

(f)

Data Subject Rights. Participant may have a number of rights under data privacy laws depending on his or her
jurisdiction, including the right to (i) request access to or copies of Data the Company processes, (ii) rectify incorrect Data, (iii)
delete Data, (iv) restrict the processing of Data, (v) restrict the portability of Data, (vi) lodge complaints with competent

authorities  in  Participant’s  jurisdiction,  and/or  (vii)  receive  a  list  with  the  names  and  addresses  of  any  potential  recipients  of
Data.  To  receive  clarification  regarding  these  rights  or  to  exercise  these  rights,  Participant  can  contact  the  Company’s  data
privacy officer at privacy@ringcentral.com.

addressed  to  the  Company  at  RingCentral,  Inc.,  20  Davis  Drive,  Belmont,  CA  94002,  U.S.A.  or  at  such  other  address  as  the

14.

Grant is Not Transferable. Except to the limited extent provided in Section 6, this grant and the rights and privileges
conferred hereby will not be transferred, assigned, pledged or hypothecated in any way (whether by operation of law or otherwise)
and  will  not  be  subject  to  sale  under  execution,  attachment  or  similar  process.  Upon  any  attempt  to  transfer,  assign,  pledge,
hypothecate  or  otherwise  dispose  of  this  grant,  or  any  right  or  privilege  conferred  hereby,  or  upon  any  attempted  sale  under  any
execution, attachment or similar process, this grant and the rights and privileges conferred hereby immediately will become null and
void.

15.

Binding  Agreement.  Subject  to  the  limitation  on  the  transferability  of  this  grant  contained  herein,  this  Award
Agreement will be binding upon and inure to the benefit of the heirs, legatees, legal representatives, successors and assigns of the
parties hereto.

16.

Additional  Conditions  to  Issuance  of  Stock.  If  at  any  time  the  Company  will  determine,  in  its  discretion,  that  the
listing, registration, qualification or rule compliance of the Shares upon any securities exchange or under U.S. or non-U.S. federal or
state  law,  tax  code  and  related  regulations  or  the  consent  or  approval  of  any  governmental  regulatory  authority  is  necessary  or
desirable as a condition to the issuance of Shares to Participant (or his or her estate) hereunder, such issuance will not occur unless
and until such listing, registration, qualification, rule compliance, consent or approval will have been completed, effected or obtained
free  of  any  conditions  not  acceptable  to  the  Company.  Where  the  Company  determines  that  the  delivery  of  the  payment  of  any
Shares will violate U.S. or non-U.S. federal or state securities laws or other applicable laws, the Company will defer delivery until
the earliest date at which the Company reasonably anticipates that the delivery of Shares will no longer cause such violation. The
Company will make all reasonable efforts to meet the requirements of any such U.S. and non-U.S. federal or state law or securities
exchange and to obtain any such consent or approval of any such governmental authority or securities exchange.

17.

Plan  Governs.  This  Award  Agreement  is  subject  to  all  terms  and  provisions  of  the  Plan.  In  the  event  of  a  conflict
between one or more provisions of this Award Agreement and one or more provisions of the Plan, the provisions of the Plan will
govern. Capitalized terms used and not defined in this Award Agreement will have the meaning set forth in the Plan.

have vested). All actions taken and all interpretations and determinations made by the Administrator in good faith will be final and
binding upon Participant, the Company and all other interested persons. No member of the Administrator will be personally liable
for any action, determination or interpretation made in good faith with respect to the Plan or this Award Agreement.

19.

Electronic  Delivery  and  Participation.  The  Company  may,  in  its  sole  discretion,  decide  to  deliver  any  documents
related to Restricted Stock Units awarded under the Plan or future Restricted Stock Units that may be awarded under the Plan by
electronic  means  or  request  Participant’s  consent  to  participate  in  the  Plan  by  electronic  means.  Participant  hereby  consents  to
receive  such  documents  by  electronic  delivery  and  agrees  to  participate  in  the  Plan  through  any  on-line  or  electronic  system
established and maintained by the Company or a third party designated by the Company.

advisor who is proficient in the English language, so as to enable Participant to understand the provisions of this Award Agreement
and the Plan. If Participant has received this Award Agreement or any other document related to the Plan translated into a language
other than English and if the meaning of the translated version is different than the English version, the English version will control.

construction of this Award Agreement.

Agreement Severable. In the event that any provision in this Award Agreement will be held invalid or unenforceable,
such  provision  will  be  severable  from,  and  such  invalidity  or  unenforceability  will  not  be  construed  to  have  any  effect  on,  the
remaining provisions of this Award Agreement.

23.

Amendment, Suspension or Termination of the Plan. By accepting this Award, Participant expressly warrants that he
or she has received an Award of Restricted Stock Units under the Plan, and has received, read and understood a description of the
Plan. Participant understands that the Plan is discretionary in nature and may be amended, suspended or terminated by the Company
at any time.

24.

Governing Law and Venue. This Award Agreement will be governed by the laws of Delaware without giving effect
to the conflict of law principles thereof. For purposes of litigating any dispute that arises under this Award of Restricted Stock Units
or this Award Agreement, the parties hereby submit to and consent to the exclusive jurisdiction of the State of California, and agree
that such litigation will be conducted exclusively in the courts of San Mateo County, California, or the federal courts for the United
States for the Northern District of California, and no other courts, where this Award of Restricted Stock Units is made and/or to be
performed.

25.

Appendix. Notwithstanding any provisions in this Award Agreement, the Restricted Stock Unit grant shall be subject

to any additional terms and conditions set forth in

any appendix to this Award Agreement for Participant’s country (the “Appendix”). Moreover, if Participant relocates to one of the
countries included in the Appendix, the additional terms and conditions for such country will apply to Participant, to the extent the
Company determines that the application of such terms and conditions is necessary or advisable for legal or administrative reasons.
The Appendix constitutes part of this Award Agreement.

26. Modifications to the Award Agreement. This Award Agreement constitutes the entire understanding of the parties on

27.

Imposition  of  Other  Requirements.  The  Company  reserves  the  right  to  impose  other  requirements  on  Participant’s
participation  in  the  Plan,  on  the  Restricted  Stock  Units  and  on  any  Shares  acquired  under  the  Plan,  to  the  extent  the  Company
determines  it  is  necessary  or  advisable  for  legal  or  administrative  reasons,  and  to  require  Participant  to  sign  any  additional
agreements or undertakings that may be necessary to accomplish the foregoing.

28. Waiver. Participant acknowledges that a waiver by the Company of breach of any provision of this Award Agreement
shall  not  operate  or  be  construed  as  a  waiver  of  any  other  provision  of  this  Award  Agreement,  or  of  any  subsequent  breach  by
Participant or any other Participant.

29.

Insider-Trading/Market-Abuse Laws. Participant acknowledges that he or she may be subject to insider-trading and/or
market-abuse  laws in applicable  jurisdictions,  including but not limited to the United States and Participant’s  country, which may
affect Participant’s ability to purchase or sell Shares acquired under the Plan during such times as Participant is considered to have
“inside  information”  regarding  the  Company  (as  defined  by  the  laws  in  applicable  jurisdictions).  Local  insider-trading  laws  and
regulations  may  prohibit  the  cancellation  or  amendment  of  orders  Participant  places  before  possessing  inside  information.
Furthermore, Participant could be prohibited from (i) disclosing the inside information to any third party (other than on a “need to
know” basis) and (ii) “tipping” third parties or causing them otherwise to buy or sell securities. Third parties include fellow Service
Providers. Any restrictions under these laws or regulations are separate from and in addition to any restrictions that may be imposed
under any applicable Company insider-trading policy. Participant is responsible for complying with any applicable restrictions, so
Participant  should  speak  to  his  or  her  personal  legal  advisor  for  further  details  regarding  any  applicable  insider-trading  and/or

received from participating in the Plan (including from any dividends paid on the Shares acquired under the Plan) in a brokerage or
bank account outside his or her country. Participant may be required to report such accounts, assets or transactions to the tax or other
authorities in his or her country. Participant also may be required to repatriate sale proceeds or other funds received as a result of
participating  in  the  Plan  to  his  or  her  country  through  a  designated  bank  or  broker  within  a  certain  time  after  receipt.  Participant
acknowledges  that  it  is  his  or  her  responsibility  to  be  compliant  with  such  regulations,  and  Participant  should  speak  to  his  or  her
personal advisor on this matter.

EXHIBIT B

APPENDIX

COUNTRY-SPECIFIC TERMS AND CONDITIONS OF RESTRICTED STOCK UNIT GRANT

Capitalized terms used but not defined in this Appendix shall have the meanings set forth in the Plan, the Notice of Grant and/or the
Terms and Conditions of Restricted Stock Unit Grant (“Terms and Conditions”).

Terms and Conditions

This Appendix includes additional terms and conditions that govern the Restricted Stock Units granted to Participant under the Plan
if Participant works or resides in one of the countries listed below. If Participant is a citizen or resident of a country (or is considered
as such for local law purposes) other than the one in which he or she is currently working and/or residing, or if Participant relocates
to another country after receiving the Restricted Stock Units, the Company will, in its discretion, determine the extent to which the
terms and conditions contained herein will be applicable to Participant.

Notifications

This Appendix also includes notifications relating to exchange control and other issues of which Participant should be aware with
respect to his or her participation in the Plan. The information is based on the exchange control, securities and other laws in effect in
the  countries  herein  as  of  January  2021.  Such  laws  are  often  complex  and  change  frequently.  As  a  result,  the  Company  strongly
recommends that Participant not rely on the notifications herein as the only source of information relating to the consequences of his
or her participation in the Plan, because the information may be outdated when Participant vests in the Restricted Stock Units and
acquires Shares, or when Participant subsequently sells Shares acquired under the Plan.

In addition, the notifications are general in nature and may not apply to Participant’s particular situation, and the Company is not in a
position to assure Participant of any particular result. Accordingly, Participant should seek appropriate professional advice as to how
the relevant laws in Participant’s country may apply to Participant’s situation.

Finally, if Participant is a citizen or resident of a country other than the one in which Participant is currently working and/or residing
(or is considered as such for local law purposes), or if Participant relocates to another country after receiving the Restricted Stock
Units, the information contained herein may not be applicable to Participant.

Terms and Conditions

AUSTRALIA

Australia Offer Document. The Company is pleased to provide Participant with this offer to participate in the Plan. This offer sets
out information regarding the grant of Restricted Stock Units to Australian resident Service Providers. This information is provided
by the Company  to ensure  compliance  of the Plan with Australian  Securities  and Investments  Commission  (“ASIC”)  Class Order
14/1000 and relevant provisions of the Corporations Act 2001.

In addition to the information  set out in this Award Agreement (including  this Appendix),  Participant  is also being provided with
copies of the following documents:

(a)

the Plan;

(b) the Plan prospectus; and

(c) Employee Information Supplement (collectively, the “Additional Documents”).

The Additional Documents provide further information to help Participant make an informed investment decision about participating
in the Plan. Neither the Plan nor the Plan prospectus is a prospectus for the purposes of the Corporations Act 2001.

Participant should not rely upon any oral statements made in relation to this offer. Participant should rely only upon the statements
contained in this Award Agreement (including this Appendix) and the Additional Documents when considering participation in the
Plan.

Notifications

Tax Information. The Plan is a plan to which Subdivision 83A-C of the Income Tax Assessment Act 1997 (Cth) applies (subject to
conditions in the Act).

Securities Law Information. Investment in Shares involves a degree of risk. Eligible employees who elect to participate in the Plan
should monitor their participation and consider all risk factors relevant to the acquisition of Shares under the Plan as set forth below
and in the Additional Documents.

The information herein is general information only. It is not advice or information that takes into account Participant’s objectives,
financial  situation  and  needs.  Participant  should  consider  obtaining  his  or  her  own  financial  product  advice  from  a  person  who  is
licensed by ASIC to give such advice.

Additional Risk Factors for Australian Residents. Participant should have regard to risk factors relevant to investment in securities
generally and, in particular, to holding Shares. For example, the price at which an individual Share is quoted on the New York Stock
Exchange  (“NYSE”)  may  increase  or  decrease  due  to  a  number  of  factors.  There  is  no  guarantee  that  the  price  of  a  Share  will
increase. Factors that may affect the price of an individual Share include fluctuations

in  the  domestic  and  international  market  for  listed  stocks,  general  economic  conditions,  including  interest  rates,  inflation  rates,
commodity and oil prices, changes to government fiscal, monetary or regulatory policies, legislation or regulation, the nature of the
markets in which the Company operates and general operational and business risks.

More  information  about  potential  factors  that  could  affect  the  Company’s  business  and  financial  results  will  be  included  in  the
Company’s most recent Annual Report on Form 10-K and the Company’s Quarterly Report on Form 10-Q. Copies of these reports
are available at www.sec.gov, on the Company’s investor’s page at ir.ringcentral.com, and upon request to the Company.

In  addition,  Participant  should  be  aware  that  the  Australian  dollar  (“AUD”)  value  of  any  Shares  acquired  under  the  Plan  will  be
affected  by  the  USD/AUD  exchange  rate.  Participation  in  the  Plan  involves  certain  risks  related  to  fluctuations  in  this  rate  of
exchange.

Common  Stock  in  a  U.S.  Corporation.  Common  stock  of  a  U.S.  corporation  is  analogous  to  ordinary  shares  of  an  Australian
corporation. Each holder of a Share is entitled to one vote. Dividends may be paid on the Shares out of any funds of the Company
legally available for dividends at the discretion of the Board. Further, Shares are not liable to any further calls for payment of capital
or for other assessment by the Company and have no sinking fund provisions, pre-emptive rights, conversion rights or redemption
provisions.

Ascertaining the Market Price of Shares. Participant may ascertain the current market price of an individual Share as traded on the
NYSE  under  the  symbol  “RNG”  at  www.nyse.com/quote/XNYS:RNG.  The  AUD  equivalent  of  that  price  can  be  obtained  at
www.rba.gov.au/statistics/frequency/exchange-rates.html. Please  note  that  this  is  not  a  prediction  of  what  the  market  price  of  the
Shares will be on any applicable vesting date or when Shares are issued to Participant (or at any other time), or of the applicable
exchange rate at such time.

Terms and Conditions

CANADA

Company’s Obligation to Pay. The following provision supplements Section 2 of the Terms and Conditions:

Notwithstanding the discretion of the Administrator to settle earned Restricted Stock Units in cash, Shares or a combination of both
as described in Section 8(d) of the Plan, vested Restricted Stock Units shall be paid to Participant in Shares only.

Termination as a Service Provider. The following provisions replace Section 10(f) of the Terms and Conditions:

For purposes of the Restricted Stock Units, Participant’s status as a Service Provider will be considered terminated (regardless of the
reason for such termination and whether or not later to be found invalid or in breach of employment laws in the jurisdiction where
Participant  is  a  Service  Provider  or  the  terms  of  Participant’s  employment  or  service  agreement,  if  any)  as  of  the  date  that  is  the
earlier  of  (i)  the  date  Participant’s  employment  or  service  relationship  terminates,  and  (ii)  the  date  Participant  receives  notice  of
termination of employment or other service

relationship.  In  either  case,  the  date  shall  exclude  any  period  during  which  notice,  pay  in  lieu  of  notice  or  related  payments  or
damages are provided or required to be provided under local law. For greater certainty, Participant will not earn or be entitled to any
pro-rated  vesting  for  that  portion  of  time  before  the  date  on  which  Participant’s  right  to  vest  terminates,  nor  will  Participant  be
entitled to any compensation for lost vesting.

Notwithstanding the foregoing, if applicable employment standards legislation explicitly requires continued participation in the Plan
during  a  statutory  notice  period,  Participant  acknowledges  that  his  or  her  right  to  participate  in  the  Plan,  if  any,  will  terminate
effective as of the last day of Participant’s minimum statutory notice period, but Participant will not earn or be entitled to pro-rata
vesting  if  the  vesting  date  falls  after  the  end  of  Participant’s  statutory  notice  period,  nor  will  Participant  be  entitled  to  any
compensation for lost vesting.

The following provisions apply if Participant resides in Quebec:

CHINA

The  following  provisions  apply  if  Participant  is  subject  to  exchange  control  restrictions  imposed  by  the  State  Administration  of
Foreign Exchange (“SAFE”), as determined by the Administrator in its sole discretion:

Terms and Conditions

Vesting  Schedule  and  Company’s  Obligation  to  Pay.  The  following  provisions  supplement  Sections  3  and  4  of  the  Terms  and
Conditions:

The Restricted Stock Units will not vest and Shares will not be issued at vesting unless the Company determines that such vesting
and the issuance and delivery of Shares comply with all relevant provisions of law. Further, the Company is under no obligation to
vest the Restricted Stock Units and/or issue Shares if the Company’s SAFE approval becomes invalid or ceases to be in effect by the
time Participant vests in the Restricted Stock Units.

Due to local regulatory requirements, the Company reserves the right to force the sale of any Shares issued upon settlement of the
Restricted Stock Units. The sale may occur (i) immediately upon issuance, (ii) following termination, (iii) following transfer to the
Company, a Parent or Subsidiary outside of China, or (iv) within any other time frame as the Company determines to be necessary or
advisable for legal or administrative reasons. Participant is required to maintain any Shares acquired under the Plan in an account at a
broker  designated  by  the  Company  (“Designated  Account”)  and  any  Shares  deposited  into  the  Designated  Account  cannot  be
transferred out of the Designated Account unless and until they are sold.

In order to facilitate the foregoing, the Company is authorized to instruct its designated broker to assist with the sale of the Shares
(on Participant’s behalf pursuant to this authorization without further consent) and Participant expressly authorizes the Company’s
designated broker to complete the sale of such Shares. Participant acknowledges that the Company’s designated broker is under no
obligation  to  arrange  for  the  sale  of  the  Shares  at  any  particular  price.  Upon  the  sale  of  the  Shares,  the  Company  will  pay  to
Participant  the  cash  proceeds  from  the  sale,  less  any  brokerage  fees  or  commissions  and  subject  to  any  obligation  to  satisfy  Tax-
Related Items. If the Shares acquired under the Plan are sold, the repatriation requirements described below shall apply.

Exchange Control Requirement.  Pursuant  to  exchange  control  requirements  in  China,  Participant  will  be  required  to  immediately
repatriate  to  China  any  cash  proceeds  from  the  sale  of  the  Shares  that  Participant  acquired  under  the  Plan  or  the  receipt  of  any
dividends paid on such Shares. Participant understands that, under applicable laws, such repatriation of the cash proceeds may need
to be effectuated through a special exchange control account established by the Company or a Parent or Subsidiary in China, and
Participant hereby consents and agrees that any proceeds from the sale of Shares or the receipt of dividends may be transferred to
such special account prior to being delivered to Participant. Participant also understands that the Company will deliver the proceeds
to  Participant  as  soon  as  possible,  but  that  there  may  be  delays  in  distributing  the  funds  to  Participant  due  to  exchange  control
requirements. Participant understands that the proceeds may be paid to Participant in U.S. dollars or in local currency, at

the Company’s discretion. If the proceeds are paid to Participant in U.S. dollars, Participant will be required to set up a U.S. dollar
bank  account  in  China  so  that  the  proceeds  may  be  deposited  into  this  account.  If  the  proceeds  are  paid  to  Participant  in  local
currency, the Company is under no obligation to secure any particular exchange conversion rate and the Company may face delays
in converting the proceeds to local currency due to exchange control restrictions.

Finally,  Participant  agrees  to  comply  with  any  other  requirements  that  may  be  imposed  by  the  Company  in  the  future  in  order  to
facilitate compliance with exchange control requirements in China.

ISRAEL

The  following  terms  and  conditions  apply  to  Participant  only  if  Participant  is  an  Israeli  tax  resident  at  the  time  of  grant  of  the
Restricted Stock Units, which were made under the capital gains trustee track of Section 102 of the Israeli Income Tax Ordinance.

Israeli  Subplan.  By  accepting  the  Restricted  Stock  Units,  Participant  understands  and  agrees  that  the  Restricted  Stock  Units  are
offered subject to and in accordance with the RingCentral, Inc. 2013 Equity Incentive Plan Israeli Subplan (the “Israeli Subplan”)
and  the  Restricted  Stock  Units  are  intended  to  qualify  as  a  102  Capital  Gains  Track  Grant  (as  defined  in  the  Israeli  Subplan).
Notwithstanding the foregoing, the Company does not undertake to maintain the qualified status of the Restricted Stock Units, and
Participant  acknowledges  that  Participant  will  not  be  entitled  to  damages  of  any  nature  whatsoever  if  the  Restricted  Stock  Units
become disqualified and no longer qualify as a 102 Capital Gains Track Grant. In the event of any inconsistencies between the Israeli
Subplan, this Award Agreement and/or the Plan, the terms of the Israeli Subplan will govern.

Further, to the extent requested by the Company or the Service Recipient, Participant agrees to execute any letter or other agreement
in connection with the grant of the Restricted Stock Units or any future Awards granted under the Israeli Subplan. If Participant fails
to comply with such request, the Restricted Stock Units may not qualify as a 102 Capital Gains Track Grant.

Awards and Shares held and/or administered by such Trustee at such time to its successor. The provisions of this Award Agreement,
including this Appendix, shall apply to the new Trustee mutatis mutandis.

Restriction on Sale. Participant acknowledges that any Shares underlying the Restricted Stock Units may not be disposed of prior to
the expiration of the Required Holding Period in order to qualify for tax treatment under the 102 Capital Gains Track. Accordingly,
Participant shall not dispose of (or request the Trustee to dispose of) any such Shares prior to the expiration of the Required Holding
Period, other than as permitted by applicable laws. For purposes of this Appendix for Israel, “dispose” shall mean any sale, transfer

Shares from the Trustee to Participant.

obligation to withhold Tax-Related Items applicable to Participant in connection with the Restricted Stock Units granted under the
Israeli Subplan.

The following provision applies to Participant only if Participant was not an Israeli tax resident at the time of grant of the Restricted
Stock Units and the Restricted Stock Units do not qualify as Section 102 capital gains trustee track grants:

Payment of Restricted Stock Units and Sale of Shares. Due to local regulatory requirements, the Company reserves the right to force
the sale of any Shares issued upon settlement of the Restricted Stock Units. Participant is required to maintain the Shares acquired in
an account at a broker designated by the Company and any Shares deposited into the account cannot be transferred out of the account

to  instruct  its  designated  broker  to  assist  with  the  mandatory  sale  (on  Participant’s  behalf  pursuant  to  this  authorization),  and
Participant expressly authorizes the Company’s designated broker to complete the sale of such Shares. Participant agrees to sign any
forms and/or consents required by the Company’s designated broker to effectuate the sale of Shares. Participant acknowledges that
the Company’s designated broker is under no obligation to arrange for the sale of the Shares at any particular price. Upon the sale of

To RingCentral, Inc. Executive Bonus Plan

2020 Performance Goals

(Effective as of January 1, 2020)

Exhibit 10.18

1. 2020  Performance  Periods  and  Performance  Goals.  For  the  calendar  year  2020,  there  are  four  quarterly  Performance
Periods, ending on March 31, June 30, September 30 and December 31, 2020 (each, a “2020 Performance Period”). For each
of  the  four  2020  Performance  Periods,  there  are  two  equally  weighted  (50%  each)  performance  goals  (each,  a  “2020
Performance  Goal”):  Revenue  and  Operating  Margin  (each  as  defined  below).  The  chart  below  set  forth  the  Revenue  and
Operating Margin Performance Goals for the four 2020 Performance Periods.

“Revenue” means as to each of the 2020 Performance Periods, the Company’s net revenues generated from third parties,
including both services revenues and product revenues as defined in the Company’s Form 10-K filed for the calendar year ended
December 31, 2019. Net revenue is defined as gross sales less any pertinent discounts, refunds or other contra-revenue amounts,
as presented on the Company’s press releases reporting its quarterly financial results.

“Operating Margin” means as to each of the 2020 Performance Periods, the Company’s non-GAAP operating income
divided  by  its  Revenue.  Non-GAAP  operating  income  means  the  Company’s  Revenues  less  cost  of  revenues  and  operating
expenses,  excluding  the  impact  of  stock-based  compensation  expense,  amortization  of  acquisition  related  intangibles,  legal
settlement  related  charges  and  as  adjusted  for  certain  acquisitions,  as  presented  on  the  Company’s  press  releases  reporting  its
quarterly financial results.

2. Funding  of  2020  Bonus  Pool.  Subject  to  the  terms  of  the  Plan,  including  but  not  limited  to  Section  3(d)  of  the  Plan,
following the end of each of the 2020 Performance Periods, the Committee will determine the extent to which each of the
2020 Performance Goals are achieved in accordance with the following guidelines.

a.

b.

If  the  Company  achieves  Revenue  in  the  2020  Performance  Period  that  is  lower  than  the  amount  of  Revenue  expected  by
analyst  consensus  estimates  after  the  Company  has  released  its  guidance  for  such  2020  Performance  Period  (“Revenue
Floor”), the 2020 Bonus Pool related to the Revenue Performance Goal for such 2020 Performance Period will not fund.

If the Company achieves Operating Margin in the 2020 Performance Period that is lower than the Operating Margin expected
by analyst consensus estimates after the Company has released its guidance for such 2020 Performance Period (“Operating
Margin Floor”), the 2020 Bonus Pool related to the Operating Margin Performance Goal for such 2020 Performance Period
will not fund.

c.

If the Company achieves Revenue that is at least equal to the Revenue Floor, the 2020 Bonus Pool related to the Revenue
Performance goal for the 2020 Performance Period will fund as follows based on the achievement relative to the applicable
Performance Goal.

Revenue: For 100% of the Bonus Pool with respect to Revenue to fund, 100% to 101% of the Performance Goal for Revenue
must be achieved. For each 0.5% of Revenue that is achieved above 101% of the Performance Goal for Revenue, the Bonus
Pool with respect to Revenue will be increased by 5%, and for each 0.5% of Revenue that is achieved below 100% of the
Performance Goal for Revenue, the Bonus Pool with respect to Revenue will be reduced by 5%.

d.

If the Company achieves Operating Margin that is at least equal to the Operating Margin Floor, the 2020 Bonus Pool related
to the Operating Margin Performance goal for the 2020 Performance Period will fund as follows based on the achievement
relative to the applicable Performance Goal.

Operating Margin: For 100% of the Bonus Pool with respect to Operating Margin to fund, 100% of the Performance Goal for
Operating Margin must be achieved. For each 0.5% of Operating Margin that is achieved above the Performance Goal for
Operating Margin, the Bonus Pool with respect to operating Margin will be increased by 5% (up to a maximum of 120%),
and for each 0.5% of Operating Margin that is achieved below the Performance Goal for Operating Margin, the Bonus Pool
with respect to Operating Margin will be reduced by 5%.

The chart below illustrates examples of the funding multiple that will apply to each Performance Goal.

* “x” equals the target bonus amount at achievement of 100%-101% of the 2020 Performance Goal for Revenue, and

equals the target bonus amount at achievement of 100% of the 2020 Performance Goal for Operating Margin. The lowest
Funding Multiple for Revenue set forth above assumes that the achievement of the 2020 Performance Goal for Revenue is equal
to at least the Revenue Floor required to fund the 2020 Bonus Plan. The maximum Funding Multiple for Operating Margin shall
be 1.20x. There is no maximum Funding Multiple for Revenue.

Illustration

For  example,  if  the  Company  achieves  its  Revenue  at  101%  of  the  2020  Performance  Goal  for  Revenue  and  achieves  its
Operating Margin at 1.3% above the 2020 Performance Goal for Operating Margin, the 2020 Bonus Pool will fund as to 106.5%,
determined as follows:

–
–

50% on achievement of the Revenue 2020 Performance Goal (50% weighted target * 1.00x)
56.5% on achievement of the Operating Margin 2020 Performance Goal (50% weighted target * 1.13x)

3. Timing of Bonus Payments. Quarterly bonuses earned under this 2020 Bonus Plan shall be paid in the quarter following the

quarter in which earned.
