  The following summary is qualified in its entirety by the more detailed
information and the Consolidated Financial Statements and notes thereto

                                  THE COMPANY
 
  VeriSign is the leading provider of digital certificate solutions and
infrastructure needed by companies, government agencies, trading partners and
individuals to conduct trusted and secure communications and commerce over the
Internet and over intranets and extranets using the Internet Protocol
(collectively, "IP Networks"). The Company has established strategic
relationships with industry leaders, including Cisco, McAfee Associates,
Microsoft, Netscape, RSA, Security Dynamics, VeriFone and VISA, to enable
widespread deployment of the Company's digital certificate technology and
products and to assure their interoperability among a wide variety of
applications. The Company's digital certificates, called Digital IDs, are
enabled in millions of copies of Microsoft and Netscape Web browsers, tens of
thousands of copies of popular Web servers and a variety of other software
applications. The Company believes that it has issued more digital certificates
than any other company, having issued over 1.5 million of its Digital IDs for
individuals and over 35,000 of its Digital IDs for Web sites. In addition to
providing Digital IDs for individuals and Web sites, the Company provides turn-
key and custom digital certificate solutions needed by organizations, such as
Dow Jones, NOVUS/Discover and VISA, to conduct trusted and secure
communications and commerce over IP networks. The Company markets its products
and services worldwide through multiple distribution channels, including the
Internet, direct sales, telesales, VARs, systems integrators and OEMs, and
intends to continue to expand these distribution channels.

                                  THE COMPANY
 
  VeriSign is the leading provider of digital certificate solutions and
infrastructure needed by companies, government agencies, trading partners and
individuals to conduct trusted and secure communications and commerce over IP
networks. A digital certificate functions as an electronic credential in the
digital world, identifying the certificate owner, authenticating the
certificate owner's membership in a given organization or community or
establishing the certificate owner's authority to engage in a given
transaction, thereby creating a framework for trusted interaction over IP
networks. The Company has established strategic relationships with industry
leaders, including Cisco, McAfee Associates, Inc. ("McAfee Associates"),
Microsoft, Netscape, RSA Data Security Inc. ("RSA"), Security Dynamics
Technologies, Inc. ("Security Dynamics"), VeriFone, Inc. ("VeriFone") and Visa
International Service Association ("VISA"), to enable widespread deployment of
the Company's digital certificate technology and products and to assure their
interoperability among a wide variety of applications. The Company's digital
certificates, called Digital IDs, are enabled in millions of copies of
Microsoft and Netscape Web browsers, tens of thousands of copies of popular
Web servers and a variety of other software applications. The Company believes
that it has issued more digital certificates than any other company, having
issued over 1.5 million of its Digital IDs for individuals and over 35,000 of
its Digital IDs for Web sites. In addition to providing Digital IDs for
individuals and Web sites, the Company also provides turn-key and custom
solutions needed by organizations, such as Dow Jones, NOVUS/Discover and VISA,
to conduct trusted and secure communications and commerce over IP networks.
 
  IP networks are revolutionizing communications and commerce because of their
global reach, accessibility, use of open standards and ability to enable real-
time interaction. The use of IP networks is beginning to extend beyond
informal messaging, general information browsing and the exchange of non-
sensitive data to a number of more valuable and sensitive activities including
business-to-business transactions and electronic data interchange ("EDI"),
online retail purchases and payments, Web-based access to account and benefits
information and secure messaging for both personal and business use. Forrester
Research estimates that Internet business-to-business commerce alone will grow
from approximately $8 billion in 1997 to more than $327 billion in 2002.
However, despite the convenience and the compelling economic incentives for
the use of IP networks, they cannot reach their full potential as a platform
for global communications and commerce until the current lack of trust and
security associated with the use of these networks is resolved. Digital
certificates are emerging as the leading technology for establishing a
framework for trusted and secure communications and commerce over IP networks,
with many Internet security protocols dictating the use of digital
certificates. Just as an individual may have many forms of credit cards and
IDs, he or she may require multiple digital certificates, each corresponding
to a unique digital relationship between the individual and an organization.
Thus, there is the potential need over time for hundreds of millions of
digital certificates to be issued and managed.
 
  The Company has invested significant resources to develop a highly reliable
and secure operations infrastructure, a modular software architecture and a
comprehensive set of security and trust practices to enable trusted and secure
communications and commerce over IP networks using digital certificates. The
Company's Digital ID Centers in Mountain View, California and Kawasaki, Japan
are designed to provide the high levels of availability, security and
scaleability required to meet the needs of customers for high volume digital
certificate issuance and management. The Company's modular WorldTrust software
architecture, which serves as the foundation for the Company's products and
services, automates many aspects of digital certificate issuance and lifecycle
management and provides the scaleability necessary to deploy millions of
digital certificates for distinct communities ranging from individual
corporations to the entire population of Internet users. The Company also has
been instrumental in defining comprehensive trust practices and procedures,
which the Company believes has been important in establishing its reputation
as the leading provider of digital certificate solutions.
 
  The Company's objective is to enhance its position as the leading provider
of digital certificate solutions and infrastructure needed to conduct trusted
and secure communications and commerce over IP networks. The Company's
strategy to achieve this objective includes leveraging its leadership position
to drive market penetration, leveraging and expanding strategic relationships
with industry leaders, maintaining leadership in technology, infrastructure
and practices and continuing to build the VeriSign brand. The Company markets
its products and services worldwide through multiple distribution channels,
including the Internet, direct sales, telesales, value-added resellers
("VARs"), systems integrators and original equipment manufacturers ("OEMs"),
and intends to continue to expand these distribution channels.
 
  The Company was incorporated in Delaware in April 1995. The Company's
executive offices are located at 1390 Shorebird Way, Mountain View, California
94043, its telephone number at this location is (650) 961-7500 and its Web
site is located at http://www.verisign.com. Information contained in the
Company's Web site is not part of this Prospectus.

                                 RISK FACTORS
 
  In addition to the other information in this Prospectus, the following
factors should be considered carefully in evaluating an investment in the
shares of Common Stock offered hereby. This Prospectus contains forward-
looking statements that involve risks and uncertainties. The Company's actual
results may differ materially from the results discussed in such forward-
looking statements. Factors that may cause such a difference include, but are
not limited to, those discussed below, in the sections entitled "Management's
Discussion and Analysis of Financial Condition and Results of Operations" and
"Business" and elsewhere in this Prospectus.
   
  Limited Operating History; History of Losses and Anticipation of Future
Losses. The Company was incorporated in April 1995 and began introducing its
products and services in June 1995. Accordingly, the Company has only a
limited operating history on which to base an evaluation of its business and
prospects. The Company's prospects must be considered in light of the risks
and uncertainties encountered by companies in the early stages of development,
particularly companies in new and rapidly evolving markets. The Company's
success will depend on many factors, including, but not limited to, the
following: the rate and timing of the growth and use of IP networks for
communications and commerce and the extent to which digital certificates are
used for such communications and commerce; the demand for the Company's
products and services; the levels of competition; the perceived security of
communications and commerce over IP networks, and of the Company's
infrastructure, products and services in particular; and the Company's
continued ability to maintain its current, and enter into additional,
strategic relationships. To address these risks the Company must, among other
things: attract and retain qualified personnel; respond to competitive
developments; successfully introduce new products and services; successfully
introduce enhancements to its existing products and services to address new
technologies and standards; and successfully market its digital certificates
and its enterprise and electronic commerce solutions. There can be no
assurance that the Company will succeed in addressing any or all of these
risks, and the failure to do so would have a material adverse effect on the
Company's business, operating results and financial condition. In addition,
the Company has experienced substantial net losses in each fiscal period since
its inception and, as of September 30, 1997, had an accumulated deficit of
$25.0 million. Such net losses and accumulated deficit resulted from the
Company's lack of substantial revenues and the significant costs incurred in
the development and sale of the Company's products and services and in the
establishment and deployment of the Company's operations infrastructure and
practices. The Company's limited operating history, the emerging nature of its
market and the factors described under "--Adoption of IP Networks" and "--
Potential Fluctuations in Quarterly Operating Results; Unpredictability of
Future Revenues," among other factors, make prediction of the Company's future
operating results difficult. In addition, the Company intends to increase its
expenditures in all areas in order to execute its business plan. As a result,
the Company expects to incur substantial additional losses for the foreseeable
future. Furthermore, to the extent the Company's majority-owned subsidiary,
VeriSign Japan, is unable to continue to fund its operations with investments
from minority shareholders, the Company may be required to fund the operations
of VeriSign Japan, which could have a material adverse effect on the Company's
business, operating results and financial condition. Although the Company has
experienced revenue growth in recent periods, there can be no assurance that
such growth rates are sustainable and, therefore, they should not be
considered indicative of future operating results. There can also be no
assurance that the Company will ever achieve significant revenues or
profitability or, if significant revenues and profitability are achieved, that
they could be sustained. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations" and "Business--Strategy."     
 
  Adoption of IP Networks. In order for the Company to be successful, IP
networks must be adopted as a means of trusted and secure communications and
commerce to a sufficient extent and within an adequate time frame. Because
trusted and secure communications and commerce over IP networks is new and
evolving, it is difficult to predict with any assurance the size of this
market and its growth rate, if any. To date, many businesses and consumers
have been deterred from utilizing IP networks for a number of reasons,
including, but not limited to, potentially inadequate development of network
infrastructure, security concerns, inconsistent quality of service, lack of
availability of cost-effective, high-speed service, limited numbers of local
access points for corporate users, inability to integrate business
applications on IP networks, the need to interoperate with multiple
 
                                       5
<PAGE>
 
and frequently incompatible products, inadequate protection of the
confidentiality of stored data and information moving across IP networks and a
lack of tools to simplify access to and use of IP networks. The adoption of IP
networks for trusted and secure communications and commerce, particularly by
individuals and entities that historically have relied upon traditional means
of communications and commerce, will require a broad acceptance of new methods
of conducting business and exchanging information. Companies and government
agencies that already have invested substantial resources in other methods of
conducting business may be reluctant to adopt a new strategy that may limit or
compete with their existing efforts. Furthermore, individuals with established
patterns of purchasing goods and services and effecting payments may be
reluctant to alter those patterns.
   
  The use of IP networks for trusted and secure communications and commerce
may not increase or may increase more slowly than expected because the
infrastructure required to support widespread trusted and secure
communications and commerce on such networks may not develop. For example, the
Internet has experienced, and may continue to experience, significant growth
in its number of users and amount of traffic. There can be no assurance that
the Internet infrastructure will continue to support the demands placed on it
by this continued growth or that the performance or reliability of the
Internet will not be adversely affected by this continued growth. In addition,
IP networks could lose their viability due to delays in the development or
adoption of new standards and protocols to handle increased levels of activity
or due to increased governmental regulation. Changes in, or insufficient
availability of, communications services to support IP networks could result
in slower response times and also adversely affect usage of IP networks. If
the market for trusted and secure communications and commerce over IP networks
fails to develop or develops more slowly than expected, or if the Internet
infrastructure does not adequately support any continued growth, the Company's
business, operating results and financial condition would be materially
adversely affected. See "--Industry Regulation" and "Business--Industry
Background" and "--Customers and Markets."     
 
  No Assurance of Market Acceptance for Digital Certificates and the Company's
Products and Services. The Company's products and services are targeted at the
market for trusted and secure communications and commerce over IP networks, a
market that is at an early stage of development and is rapidly evolving.
Accordingly, demand for and market acceptance of digital certificate solutions
are subject to a high level of uncertainty. There can be no assurance that
digital certificates will gain market acceptance as a necessary element of
trusted and secure communications and commerce over IP networks. In addition,
there can be no assurance that the market for the Company's products and
services will develop in a timely manner, or at all, or that demand for the
Company's products and services will emerge or be sustainable. The factors
that may affect the level of market acceptance of digital certificates and,
consequently, the Company's products and services, include the following:
market acceptance of products and services based upon authentication
technologies other than those used by the Company; public perception of the
security of digital certificates and of the inherent security levels of IP
networks; the ability of the Internet infrastructure to accommodate increased
levels of usage; and the enactment of government regulations affecting
communications and commerce over IP networks. Even if digital certificates
achieve market acceptance, there can be no assurance that the Company's
products and services will adequately address the market's requirements. If
digital certificates do not achieve market acceptance in a timely manner and
sustain such acceptance, or if the Company's products and services in
particular do not achieve or sustain market acceptance, the Company's
business, operating results and financial condition would be materially
adversely affected. See "Business--Industry Background" and "--Customers and
Markets."
 
  Potential Fluctuations in Quarterly Operating Results; Unpredictability of
Future Revenues. The Company's operating results have varied on a quarterly
basis during its short operating history and may fluctuate significantly in
the future as a result of a variety of factors, many of which are outside the
Company's control. Factors that may affect the Company's quarterly operating
results include the following: market acceptance of digital certificates;
market acceptance of its products and services, particularly VeriSign OnSite,
VeriSign V-Commerce and VeriSign SET; the long sales and implementation cycles
for and potentially large order sizes of certain of the Company's products and
services; the timing and execution of individual contracts; the timing of
releases of new versions of Internet browsers or other third-party software
products in which the Company's public root keys are embedded; customer
renewal rates for the Company's products and services; the Company's
 
                                       6
<PAGE>
 
success in marketing other products and services to its existing customer base
and to new customers; development of the Company's direct and indirect
distribution channels; market acceptance of the Company's or competitors' new
products and services; the amount and timing of expenditures relating to
expansion of the Company's operations; price competition or pricing changes;
general economic conditions and economic conditions specific to the Internet,
intranet and extranet industries. Any one of these factors could cause the
Company's revenues and operating results to vary significantly in the future.
In addition, the Company will need to expand its operations and attract,
integrate, retain and motivate a substantial number of sales and marketing and
research and development personnel. The timing of such expansion and the rate
at which new personnel become productive could cause material fluctuations in
the Company's quarterly results of operations. See "Business--Industry
Background" and "--Strategy."
 
  The Company's limited operating history and the emerging nature of its
market make prediction of future revenues difficult. The Company's expense
levels are based, in part, on its expectations regarding future revenues, and
to a large extent such expenses are fixed, particularly in the short term.
There can be no assurance that the Company will be able to predict its future
revenues accurately and the Company may be unable to adjust spending in a
timely manner to compensate for any unexpected revenue shortfall. Accordingly,
any significant shortfall of revenues in relation to the Company's
expectations could cause significant declines in the Company's quarterly
operating results.
 
  Due to all of the foregoing factors, the Company's quarterly revenues and
operating results are difficult to forecast. The Company believes that period-
to-period comparisons of its operating results will not necessarily be
meaningful and should not be relied upon as an indication of future
performance. Also, it is likely that the Company's operating results will fall
below the expectations of the Company, securities analysts or investors in
some future quarter. In such event, the market price of the Company's Common
Stock could be materially and adversely affected. See "Management's Discussion
and Analysis of Financial Condition and Results of Operations."
 
  System Interruption and Security Breaches. The Company's success is largely
dependent on the uninterrupted operation of its Digital ID Centers and its
other computer and communications systems, which is dependent on the Company's
ability to protect such systems from loss, damage or interruption caused by
fire, earthquake, power loss, telecommunications failure or other events
beyond the Company's control. Most of the Company's systems are located at,
and most of its customer information is stored in, its facilities in Mountain
View, California and Kawasaki, Japan, areas susceptible to earthquakes.
Although the Company believes that its existing and planned precautions are
adequate to prevent any significant loss of information or system outage,
there can be no assurance that unanticipated problems will not cause such loss
or failure. Any damage or failure that causes interruptions in the Company's
Digital ID Centers and its other computer and communications systems could
have a material adverse effect on the Company's business, operating results
and financial condition. In addition, the ability of the Company to issue
digital certificates is also dependent on the efficient operation of the
Internet connections from customers to its Digital ID Centers. Such
connections, in turn, are dependent upon efficient operation of Web browsers,
Internet Service Providers ("ISPs") and Internet backbone service providers,
all of which have had periodic operational problems or experienced outages in
the past. Any such problems or outages could adversely affect customer
satisfaction with the Company's products and services, which could have a
material adverse effect on the Company's business, operating results and
financial condition. The Company's success also depends in large part upon the
scaleability of its systems, which have not been tested at high volumes. As
such, it is possible that a substantial increase in demand for the Company's
products and services could cause interruptions in the Company's systems that
could adversely affect the Company's ability to deliver its products and
services. Any such interruptions could have a material adverse effect on the
Company's business, operating results and financial condition.
 
  The Company retains confidential customer information in its Digital ID
Centers. It is critical to the Company's business strategy that the Company's
facilities and infrastructure remain secure and that such facilities and
infrastructure are perceived by the marketplace to be secure. Despite the
implementation of security measures, the Company's infrastructure may be
vulnerable to physical break-ins, computer viruses, attacks by
 
                                       7
<PAGE>
 
hackers or similar disruptive problems, and it is possible that in the future
the Company may have to expend additional financial and other resources to
further address such problems. Any physical or electronic break-ins or other
security breaches or compromises of the private root keys stored at the
Company's Digital ID Centers may jeopardize the security of information stored
on the Company's premises or stored in and transmitted through the computer
systems and networks of the businesses and individuals utilizing the Company's
products or services, which could result in significant liability to the
Company and could deter existing and potential customers from using the
Company's products and services. Such an occurrence could result in adverse
publicity and therefore adversely affect the market's perception of the
security of communications and commerce over IP networks as well as of the
security or reliability of the Company's products and services, which would
have a material adverse effect on the Company's business, operating results
and financial condition. See "Business--The VeriSign Solution," "--Strategy,"
"--Infrastructure," "--Security and Trust Practices" and "--Facilities."
 
  Competition. The Company's digital certificate solutions are targeted at the
new and rapidly evolving market for trusted and secure communications and
commerce over IP networks. Although the competitive environment in this market
has yet to develop fully, the Company anticipates that it will be intensely
competitive, subject to rapid change and significantly affected by new product
and service introductions and other market activities of industry
participants.
 
  The Company's primary competitors are Entrust Technologies, Inc.
("Entrust"), GTE CyberTrust Solutions Incorporated ("GTE/CyberTrust") and
International Business Machines Corporation ("IBM"). The Company also
experiences competition from a number of smaller companies that provide
digital certificate solutions. The Company expects that competition from
established and emerging companies in the financial and telecommunications
industries will increase in the near term, and that the Company's primary
long-term competitors may not yet have entered the market. Netscape has
introduced software products that enable the issuance and management of
digital certificates, and the Company believes that other companies could
introduce such products. There can be no assurance that additional companies
will not offer digital certificate solutions that are competitive with those
of the Company. Increased competition could result in pricing pressures,
reduced margins or the failure of the Company's products and services to
achieve or maintain market acceptance, any of which could have a material
adverse effect on the Company's business, operating results and financial
condition.
   
  Several of the Company's current and potential competitors have longer
operating histories and significantly greater financial, technical, marketing
and other resources than the Company and therefore may be able to respond more
quickly than the Company to new or changing opportunities, technologies,
standards and customer requirements. Many of these competitors also have
broader and more established distribution channels that may be used to deliver
competing products or services directly to customers through bundling or other
means. If such competitors were to bundle with their products competing
products or services for their customers, the demand for the Company's
products and services might be substantially reduced and the ability of the
Company to distribute its products successfully and the utilization of its
services would be substantially diminished. In addition, browser companies
that embed the Company's root keys or otherwise feature the Company as a
provider of digital certificate solutions in their Web browsers or on their
Web sites could also promote competitors of the Company or charge the Company
substantial fees for such promotions in the future. New technologies and the
expansion of existing technologies may increase the competitive pressures on
the Company. There can be no assurance that competing technologies developed
by others or the emergence of new industry standards will not adversely affect
the Company's competitive position or render its products or technologies
noncompetitive or obsolete. In addition, the market for digital certificates
is nascent and is characterized by announcements of collaborative
relationships involving competitors of the Company. The existence or
announcement of such relationships could adversely affect the Company's
ability to attract and retain customers. As a result of the foregoing and
other factors, there can be no assurance that the Company will compete
effectively with current or future competitors or that competitive pressures
faced by the Company will not have a material adverse effect on the Company's
business, operating results and financial condition.     
 
  In connection with the Company's first round of financing, RSA contributed
certain technology to the Company and entered into a noncompetition agreement
with the Company pursuant to which RSA agreed that it
 
                                       8
<PAGE>
 
   
would not compete with the Company's certificate authority business for a
period of five years. This noncompetition agreement will expire in April 2000.
The Company believes that, because RSA (which is now a wholly-owned subsidiary
of Security Dynamics) has already developed expertise in the area of
cryptography, its barriers to entry would be lower than those that would be
encountered by other potential competitors of the Company should it choose to
enter any of the Company's markets. If RSA were to enter into the digital
certificate market, the Company's business, operating results and financial
condition could be materially adversely affected. See "Business--Competition."
    
  Rapid Technological Change; New Product and Services Introductions.
Substantially all of the Company's limited revenues to date have been derived
from the sale of digital certificate products and related services. These
products and services are expected to account for substantially all of the
Company's revenues for the foreseeable future. The emerging market for digital
certificate products and related services is characterized by rapid
technological developments, frequent new product introductions and evolving
industry standards. The emerging nature of this market and its rapid evolution
will require that the Company continually improve the performance, features and
reliability of its products and services, particularly in response to
competitive offerings and that it introduce new products and services or
enhancements to existing products and services as quickly as possible and prior
to its competitors. The success of new product introductions is dependent on
several factors, including proper new product definition, timely completion and
introduction of new products, differentiation of new products from those of the
Company's competitors and market acceptance of the Company's new products and
services. There can be no assurance that the Company will be successful in
developing and marketing new products and services that respond to competitive
and technological developments and changing customer needs. The failure of the
Company to develop and introduce new products and services successfully on a
timely basis and to achieve market acceptance for such products and services
could have a material adverse effect on the Company's business, operating
results and financial condition. In addition, the widespread adoption of new
Internet, networking or telecommunication technologies or standards or other
technological changes could require substantial expenditures by the Company to
modify or adapt its products and services. To the extent that a method other
than digital certificates is adopted to enable trusted and secure communications
and commerce over IP networks, sales of the Company's existing and planned
products and services will be adversely affected and the Company's products and
services could be rendered unmarketable or obsolete, which would have a material
adverse effect on the Company's business, operating results and financial
condition. The Company believes there is a time-limited opportunity to achieve
market share, and there can be no assurance that the Company will be successful
in achieving widespread acceptance of its products and services or in achieving
market share before competitors offer products and services with features
similar to the Company's current offerings. Any such failure by the Company
could have a material adverse effect on the Company's business, operating
results and financial condition. See "Business--Products and Services" and "--
Research and Development."
 
  Management of Growth and Expansion. The Company is currently experiencing a
period of significant expansion. The Company's historical growth has placed,
and such growth and any further growth is likely to continue to place, a
significant strain on the Company's managerial, operational, financial and
other resources. The Company has grown from 30 employees at December 31, 1995
to 162 employees at September 30, 1997. In addition, the Company has opened
additional sales offices and has significantly expanded its operations during
this time period. The Company's future success will depend, in part, upon the
ability of its senior management to manage growth effectively, which will
require the Company to implement additional management information systems, to
develop further its operating, administrative, financial and accounting
systems and controls and to maintain close coordination among its engineering,
accounting, finance, marketing, sales and operations organizations. Any
failure to implement or improve systems or controls or to manage any future
growth and expansion effectively could have a material adverse effect on the
Company's business, operating results and financial condition. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations."
 
  Dependence on Key Personnel. The Company's future success will be highly
dependent on the performance of its senior management team and other key
employees, many of whom have worked together for only a short
 
                                       9
<PAGE>
 
period of time. For example, the Company has only recently hired its Vice
President of Sales and Field Operations. The Company's success will also
depend on its ability to attract, integrate, motivate and retain additional
highly skilled technical and sales and marketing personnel. There is intense
competition for senior management and technical and sales and marketing
personnel in the areas of the Company's activities. In addition, the Company's
stringent hiring practices for all operations personnel and executive
management and for certain engineering personnel, which consist of background
checks into prospective employees' criminal and financial histories, further
limit the number of qualified persons for such positions. See "Business--
Security and Trust Practices." The Company has no employment agreements with
any of its key executives. In addition, the Company does not maintain key
person life insurance for any of its officers or key employees other than
Stratton D. Sclavos, its President and Chief Executive Officer. The loss of
the services of any of the Company's senior management team or other key
employees or the failure of the Company to attract, integrate, motivate and
retain additional key employees could have a material adverse effect on the
Company's business, operating results and financial condition. See "Business--
Employees" and "Management."
 
  Need to Establish and Maintain Strategic Relationships. A significant
business strategy of the Company is to enter into strategic or other similar
collaborative relationships in order to offer products and services to a
larger customer base than could be reached through direct sales and marketing
efforts. The Company will need to enter into additional strategic
relationships to execute its business plan. There can be no assurance that the
Company will be able to enter into additional, or maintain its existing,
strategic relationships on commercially reasonable terms, if at all. If the
Company were unable to enter into additional strategic relationships or
maintain its existing strategic relationships, it would be required to devote
substantially more resources to the distribution, sale and marketing of its
products and services than it would otherwise plan to do. Furthermore, as a
result of the Company's emphasis on these relationships, the Company's success
will depend both on the ultimate success of the other parties to such
relationships, particularly in the use and promotion of IP networks for
trusted and secure communications and commerce, and on the ability of these
parties to market the Company's products and services successfully. Failure of
one or more of the Company's strategic relationships to result in the
development and maintenance of a market for the Company's products and
services could have a material adverse effect on the Company's business,
operating results and financial condition.
   
  In addition, the Company's existing strategic relationships do not, and any
future strategic relationships may not, afford the Company any exclusive
marketing or distribution rights. There can be no assurance that the other
parties to such relationships view their relationships with the Company as
significant for their own businesses or that they will not reduce their
commitment to the Company at any time in the future. In addition, there can be
no assurance that such parties will not pursue alternative technologies or
develop alternative products and services in addition to or in lieu of the
Company's products and services either on their own or in collaboration with
others, including the Company's competitors. Any future inability of the
Company to maintain its strategic relationships or to enter into additional
strategic relationships could have a material adverse effect on the Company's
business, operating results and financial condition. See "Business--Strategy,"
"--Strategic Relationships" and "--Marketing, Sales and Distribution."     
 
  Risk of Defects. Products as complex as those offered or developed by the
Company frequently contain undetected defects or failures that may be detected
at any point in the product's life. There can be no assurance that, despite
testing by the Company and potential customers, defects or errors will not
occur in existing or new products, which could result in loss of or delay in
revenues, loss of market share, failure to achieve market acceptance,
diversion of development resources, injury to the Company's reputation,
increased insurance costs or increased service and warranty costs, any of
which could have a material adverse effect on the Company's business,
operating results and financial condition. Furthermore, the Company often
renders implementation, customization, consulting and other technical services
in connection with the implementation of the Company's enterprise and
electronic commerce solutions and its digital certificate service and product
development agreements. The performance of these services typically involves
working with sophisticated software, computing and networking systems. The
Company's failure or inability to meet customer expectations or project
milestones in a timely manner could also result in loss of or delay in
revenues, loss of market share, failure to achieve market acceptance, injury
to reputation and increased costs. Because customers rely on the Company's
 
                                      10

digital certificate solutions for critical security applications, any
significant defects or errors in the Company's products or services, or in the
products of third parties that embed the Company's products, might discourage
such third parties or other customers from utilizing the Company's products
and services or result in tort or warranty claims, which could have a material
adverse effect on the Company's business, operating results and financial
condition. Although the Company attempts to reduce the risk of losses
resulting from such claims through warranty disclaimers and liability
limitation clauses in its sales agreements, there can be no assurance that
such contractual provisions would be enforceable in every instance or at all.
Furthermore, although the Company maintains errors and omissions insurance,
there can be no assurance that such insurance coverage will adequately cover
the Company for such claims or that such other measures will be effective in
limiting the Company's liability. If a court refused to enforce the liability-
limiting provisions of the Company's contracts for any reason, or if
liabilities arose that were not contractually limited or adequately covered by
insurance, the Company's business, operating results and financial condition
could be materially and adversely affected. See "Business--Products and
Services" and "--Research and Development."     
 
  Potentially Lengthy Sales and Implementation Cycles for Certain Products and
Services. A key element of the Company's strategy is to market certain of its
products and services directly to large companies and government agencies.
Based on its sales experience to date, the Company expects that the sale and
implementation of its enterprise and electronic commerce solutions to such
entities will typically involve a lengthy education process and a significant
technical evaluation and commitment of capital and other resources. The sale
and implementation of the Company's enterprise and electronic commerce
solutions will be subject to the risk of delays associated with customers'
internal budget and other procedures for approving large capital expenditures,
deploying new technologies within their networks and testing and accepting new
technologies that affect key operations. For these and other reasons, the
sales and implementation cycles associated with certain of the Company's
products and services are expected to be lengthy, potentially lasting from
three to 12 months, and are expected to be subject to a number of significant
risks that are beyond the Company's control. Because of the anticipated
lengthy sales and implementation cycle and the potentially large size of such
orders, if orders forecasted for a specific customer for a particular quarter
are not realized or revenues are not otherwise recognized in that quarter, the
Company's operating results for that quarter could be materially adversely
affected. See "--Potential Fluctuations in Quarterly Operating Results;
Unpredictability of Future Revenues" and "Management's Discussion and Analysis
of Financial Condition and Results of Operations."
 
  Risks Relating to Cryptography Technology. The Company's digital certificate
products and related services are dependent on the use of public key
cryptography technology, which depends in part on the application of certain
mathematical principles known as "factoring." The security afforded by public
key cryptography technology is predicated on the assumption that the factoring
of the composite of large prime numbers is difficult. Should an easy factoring
method be developed, then the security afforded by encryption products
utilizing public key cryptography technology would be reduced or eliminated.
Furthermore, any significant advance in techniques for attacking cryptographic
systems could also render some or all of the Company's existing products and
services obsolete or unmarketable. There can be no assurance that such
developments will not occur. Moreover, even if no breakthroughs in factoring
or other methods of attacking cryptographic systems are made, factoring
problems can theoretically be solved by computer systems significantly faster
and more powerful than those presently available. If such improved techniques
for attacking cryptographic systems are ever developed, the Company would
likely have to reissue digital certificates to some or all of its customers,
which could adversely affect market perception of the reliability of the
Company's products and services or otherwise have a material adverse effect on
the Company's business, operating results and financial condition. In the past
there have been public announcements of the successful decoding of certain
cryptographic messages. The publicity around any breaches could adversely
affect the public perception as to the safety of the public key cryptography
technology included in the Company's digital certificates. Such adverse public
perception could have a material adverse effect on the Company's business,
operating results and financial condition. See "Business--Industry Background"
and "--Products and Services."
 
  Risks Associated with International Operations. Revenues of VeriSign Japan
and revenues from other international customers accounted for approximately
15% of the Company's revenues for the nine months ended
 
                                      11
<PAGE>
 
September 30, 1997. A key component of the Company's strategy is to expand its
international operations and its international sales and marketing activities.
Expansion into these markets has required and will continue to require
significant management attention and resources and may require the Company to
localize its products and services for a particular market and to enter into
international distribution and operating relationships. The Company has
limited experience in localizing its products and in developing international
distribution or operating relationships. There can be no assurance that the
Company will be successful in expanding its product and service offerings into
international markets. In addition to the uncertainty regarding the Company's
ability to generate revenues from foreign operations and expand its
international presence, there are certain risks inherent in doing business on
an international basis, including, among others, regulatory requirements,
legal uncertainty regarding liability, export and import restrictions, tariffs
and other trade barriers, difficulties in staffing and managing foreign
operations, longer payment cycles, problems in collecting accounts receivable,
political instability, seasonal reductions in business activity and
potentially adverse tax consequences, any of which could adversely affect the
success of the Company's international operations. All of the Company's
international revenues from sources other than VeriSign Japan are denominated
in U.S. dollars. To the extent the Company expands its international
operations and has additional portions of its international revenues
denominated in foreign currencies, the Company could become subject to
increased risks relating to foreign currency exchange rate fluctuations. There
can be no assurance that one or more of the factors discussed above will not
have a material adverse effect on the Company's future international
operations and, consequently, on the Company's business, operating results and
financial condition. See "--Industry Regulation," "Management's Discussion and
Analysis of Financial Condition and Results of Operations," "Business--
Strategy" and "--Marketing, Sales and Distribution."
 
  Uncertain Maintenance and Strengthening of the VeriSign Brand. The Company
believes that maintaining and strengthening the VeriSign brand is critical to
achieving widespread acceptance of its digital certificates and related
products and services and that the importance of brand recognition will
increase as competition in the market for digital certificates and related
products and services increases. Promoting and positioning the VeriSign brand
will depend largely on the success of the Company's marketing efforts and the
ability of the Company to provide, on an uninterrupted basis, high quality,
secure, trustworthy and cost effective digital certificate solutions. The
Company will also be dependent on the success of its strategic relationships
in order to promote its brand and increase brand awareness. See "--Need to
Establish and Maintain Strategic Relationships." If current or potential
customers do not perceive the Company's products and services as secure or
trustworthy, the Company will be unsuccessful in maintaining and strengthening
its brand. Furthermore, in order to promote the VeriSign brand in response to
competitive pressures, the Company may find it necessary to increase its
marketing budget or otherwise increase its financial commitment to creating
and maintaining brand loyalty among customers. If the Company fails to promote
and maintain its brand or incurs excessive expenses in an attempt to promote
and maintain its brand, or if the Company's existing or future strategic
relationships fail to promote the Company's brand or increase brand awareness,
the Company's business, operating results and financial condition could be
materially adversely affected. See "Business--Strategy" and "--Marketing,
Sales and Distribution."
 
  Dependence on Authentication Information. The Company relies upon
information provided by third-party sources to authenticate the identity of
customers requesting certain of the Company's digital certificates. This
information is presently only available from a limited number of sources and
the Company currently procures such information from single sources. The
Company's reliance on these single sources involves certain risks and
uncertainties, including the possibility of delayed or discontinued
availability. Any such delay or unavailability, coupled with any inability of
the Company to develop alternative sources quickly and cost-effectively, could
materially impair the Company's ability to deliver certain of its digital
certificates on a timely basis and result in the cancellation of orders,
increased costs and injury to reputation, which could have a material adverse
effect on the Company's business, operating results and financial condition.
The Company's reliance on third-party information sources for authentication
has also limited the distribution of certain of its digital certificates
outside of the United States, where access to such sources has been
unavailable or limited. Additionally, accurate authentication of the identity
of the individuals and entities to which the Company issues its digital
certificates is necessary for such digital certificates to provide security.
Therefore, the inaccuracy of authentication information
 
                                      12
<PAGE>
 
on which the Company relies, including information the Company receives from
third parties, could result in material injury to the Company's reputation and
tort or warranty claims from customers relying upon the Company's digital
certificates, which could have a material adverse effect on the Company's
business, operating results and financial condition. See "--Risk of Defects"
and "Business--Products and Services."
 
  Industry Regulation. Exports of software products utilizing encryption
technology are generally restricted by the U.S. and various foreign
governments. All cryptographic products require export licenses from certain
U.S. government agencies. Although the Company has obtained approval to export
its Global Server ID product and none of the Company's other products and
services is currently subject to export controls under U.S. law, there can be
no assurance that the list of products and countries for which export approval
is required, and the regulatory policies with respect thereto, will not be
revised from time to time to include digital certificate products and related
services, or that the Company will be able to obtain necessary regulatory
approvals for the export of future products. The inability of the Company to
obtain required approvals under these regulations could adversely affect the
ability of the Company to make international sales. Furthermore, competitors
of the Company may also seek to obtain approvals to export products that could
increase the amount of competition faced by the Company. There are currently
no federal laws or regulations that specifically control certification
authorities, but a limited number of states have enacted legislation or
regulations with respect to certification authorities. If the market for
digital certificates grows, the United States, state or foreign governments
may choose to enact further regulations governing digital certificate
authorities or other providers of digital certificate products and related
services. Such regulations or the costs of complying with such regulations
could have a material adverse effect on the Company's business, operating
results and financial condition.
 
  Many companies conducting commercial transactions over IP networks do not
collect sales or other similar taxes with respect to shipments of goods into
other states or foreign countries or with respect to other transactions
conducted between parties in different states or countries. It is possible
that states or foreign countries may seek to impose sales taxes on out of
state companies that engage in commerce over IP networks. In the event that
states or foreign countries succeed in imposing sales or other taxes on
Internet commerce, the growth of the use of IP networks for commerce could
slow substantially, which could have a material adverse effect on the
Company's business, operating results and financial condition.
 
  Due to the increasing popularity of the Internet and other IP networks, it
is possible that laws and regulations may be enacted covering issues such as
user privacy, pricing, content and quality of products and services. For
example, the Telecommunications Act of 1996 prohibits the transmission over
the Internet of certain types of information and content. The increased
attention focused upon these issues as a result of the adoption of other laws
or regulations may reduce the rate of growth of the Internet or the use of
other IP networks, which in turn could result in decreased demand for the
Company's products and services or could otherwise have a material adverse
effect on the Company's business, operating results and financial condition.
See "Business--Industry Background."
 
  Intellectual Property; Potential Litigation. The Company relies primarily on
a combination of copyrights, trademarks, trade secret laws, restrictions on
disclosure and other methods to protect its intellectual property and trade
secrets. The Company also enters into confidentiality agreements with its
employees and consultants, and generally controls access to and distribution
of its documentation and other proprietary information. Despite these
precautions, it may be possible for a third party to copy or otherwise obtain
and use the Company's intellectual property or trade secrets without
authorization. In addition, there can be no assurance that others will not
independently develop substantially equivalent intellectual property. There
can be no assurance that the precautions taken by the Company will prevent
misappropriation or infringement of its technology. A failure by the Company
to protect its intellectual property in a meaningful manner could have a
material adverse effect on the Company's business, operating results and
financial condition. In addition, litigation may be necessary in the future to
enforce the Company's intellectual property rights, to protect the Company's
trade secrets or to determine the validity and scope of the proprietary rights
of others. Such litigation could result in substantial costs and diversion of
management and technical resources, either of which could have a material
adverse effect on the Company's business, operating results and financial
condition.
 
                                      13
<PAGE>
 
   
  The Company also relies on certain licensed third-party technology, such as
public key cryptography technology licensed from RSA and other technology that
is used in the Company's products to perform key functions. There can be no
assurance that these third-party technology licenses will continue to be
available to the Company on commercially reasonable terms or at all, and the
loss of any of these technologies could have a material adverse effect on the
Company's business, operating results and financial condition. Moreover, in
the Company's current license agreements, the licensor has agreed to defend,
indemnify and hold the Company harmless with respect to any claim by a third
party that the licensed software infringes any patent or other proprietary
right. Although these licenses are fully paid, there can be no assurance that
the outcome of any litigation between the licensor and a third party or
between the Company and a third party will not lead to royalty obligations of
the Company for which the Company is not indemnified or for which such
indemnification is insufficient, or that the Company will be able to obtain
any additional license on commercially reasonable terms or at all. In the
future, the Company may seek to license additional technology to incorporate
in its products and services. There can be no assurance that any third-party
technology licenses that the Company may be required to obtain in the future
will be available to the Company on commercially reasonable terms or at all.
The loss of or inability to obtain or maintain any of these technology
licenses could result in delays in introduction of the Company's products or
services until equivalent technology, if available, is identified, licensed
and integrated, which could have a material adverse effect on the Company's
business, operating results and financial condition.     
   
  From time to time, the Company has received, and may receive in the future,
notice of claims of infringement of other parties' proprietary rights. In
September 1995, the Company applied to the United States Patent and Trademark
Office to register the VeriSign name as a trademark. VeriFone, Inc.
("VeriFone") challenged the validity of the Company's application in August
1996 and, in September 1996, commenced a civil action in federal district
court alleging trademark infringement and unfair competition. The parties
settled this litigation on November 21, 1997, entered into a licensing
arrangement and are currently negotiating an OEM agreement. The Company also
issued an aggregate of 250,000 shares of Common Stock to VeriFone in
connection with the foregoing transactions. There can be no assurance that
infringement or other claims will not be asserted or prosecuted against the
Company in the future or that any past or future assertions or prosecutions
will not materially adversely affect the Company's business, operating results
and financial condition. Any such claims, with or without merit, could be
time-consuming, result in costly litigation and diversion of technical and
management personnel, cause product shipment delays or require the Company to
develop non-infringing technology or enter into royalty or licensing
agreements. Such royalty or licensing agreements, if required, may not be
available on terms acceptable to the Company, or at all. In the event of a
successful claim of product infringement against the Company and the failure
or inability of the Company to develop non-infringing technology or license
the infringed or similar technology on a timely basis, the Company's business,
operating results and financial condition could be materially adversely
affected. See "Business--Intellectual Property."     
 
  Year 2000 Compliance. Many currently installed computer systems and software
products are coded to accept only two digit entries in the date code field.
These date code fields will need to accept four digit entries to distinguish
21st century dates from 20th century dates. As a result, many companies'
software and computer systems may need to be upgraded or replaced in order to
comply with such "Year 2000" requirements. Although the Company believes that
its products and systems are Year 2000 compliant, the Company utilizes third-
party equipment and software that may not be Year 2000 compliant. Failure of
such third-party equipment or software to operate properly with regard to the
year 2000 and thereafter could require the Company to incur unanticipated
expenses to remedy any problems, which could have a material adverse effect on
the Company's business, operating results and financial condition.
Furthermore, the purchasing patterns of customers or potential customers may
be affected by Year 2000 issues as companies expend significant resources to
correct their current systems for Year 2000 compliance. These expenditures may
result in reduced funds available to implement the infrastructure needed to
conduct trusted and secure communications and commerce over IP networks or to
purchase products and services such as those offered by the Company, which
could have a material adverse effect on the Company's business, operating
results and financial condition. See "Business--Industry Background."

  Future Capital Needs; Uncertainty of Additional Funding. The Company may
require additional capital to finance its growth and marketing and research
and development projects beyond the next 12 months. The Company's capital
requirements will depend on many factors including, but not limited to, demand
for the Company's products and services and the extent to which such products
achieve market acceptance and the timing of such market acceptance, the timing
of and extent to which the Company invests in new technology, the expenses of
sales and marketing and new product development, the extent to which
competitors are successful in developing their own products and services and
increasing their own market share and brand awareness, the success of the
Company's strategic relationships, the costs involved in maintaining and
enforcing intellectual property rights, the level and timing of revenues,
available borrowings under line of credit arrangements, the degree and timing
of growth of IP networks for trusted and secure communications and commerce,
and other factors. To the extent that resources are insufficient to fund the
Company's activities, the Company may need to raise additional funds through
public or private financing, strategic relationships or other arrangements.
There can be no assurance that such additional funding, if needed, will be
available on terms attractive to the Company, or at all. Strategic
relationships, if necessary to raise additional funds, may require the Company
to relinquish rights to certain of its technologies or products. The failure
of the Company to raise capital when needed could have a material adverse
effect on the Company's business, operating results and financial condition.
If additional funds are raised through the issuance of equity securities, the
percentage ownership of the Company by its then-current stockholders would be
reduced. Furthermore, such equity securities might have rights, preferences or
privileges senior to those of the Company's Common Stock. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations--
Liquidity and Capital Resources."
 
  Certain Anti-Takeover Provisions. Upon completion of this offering, the
Company's Board of Directors will have the authority to issue up to 5,000,000
shares of Preferred Stock and to determine the price, rights, preferences,
privileges and restrictions, including voting rights, of those shares without
any further vote or action by the stockholders. The rights of the holders of
Common Stock will be subject to, and may be adversely affected by, the rights
of the holders of any Preferred Stock that may be issued in the future. The
issuance of Preferred Stock, while providing flexibility in connection with
possible financings, acquisitions or other corporate purposes, may have the
effect of delaying, deferring or preventing a change in control of the
Company, may discourage bids for the Company's Common Stock at a premium over
the market price of the Common Stock and may adversely affect the market price
of, and the voting and other rights of the holders of, the Common Stock. The
Company has no current plans to issue shares of Preferred Stock. In addition,
certain provisions of the Company's Amended and Restated Bylaws will have the
effect of delaying, deferring or preventing a change of control of the
Company. These provisions will provide, among other things, that the Board of
Directors is divided into three classes to serve staggered three-year terms,
that stockholders may not take actions by written consent and that the ability
of stockholders to call special meetings will be restricted. In addition, the
Company is subject to the anti-takeover provisions of Section 203 of the
Delaware General Corporation Law, which will prohibit the Company from
engaging in a "business combination" with an "interested stockholder" for a
period of three years after the date of the transaction in which the person
became an interested stockholder, unless the business combination is approved
in a prescribed manner. The Company's indemnity agreements provide and the
Company's Amended and Restated Certificate of Incorporation and Amended and
Restated Bylaws will provide that the Company will indemnify officers and
directors against losses that they may incur in investigations and legal
proceedings resulting from their services to the Company, which may be broad
enough to include services in connection with takeover defense measures. Such
provisions may have the effect of preventing changes in the management of the
Company. See "Description of Capital Stock."
 
  Shares Eligible for Future Sale. Sales of a substantial number of shares of
Common Stock in the public market following this offering could adversely
affect the market price of the Company's Common Stock. The number of shares of
Common Stock available for sale in the public market is limited by
restrictions under the Securities Act of 1933, as amended (the "Securities
Act"), and lock-up agreements executed by each of the security holders of the
Company under which such security holders have agreed not to sell or otherwise
dispose of any of their shares for a period of 180 days after the date of this
Prospectus without the prior written consent
 
                                      15

of Morgan Stanley & Co. Incorporated. Morgan Stanley & Co. Incorporated may,
however, in its sole discretion and at any time without notice, release all or
any portion of the shares subject to lock-up agreements. In addition to the
          shares of Common Stock offered hereby (assuming no exercise of the
Underwriters' over-allotment option), there will be 17,018,509 shares of
Common Stock outstanding as of the date of this Prospectus, all of which are
"restricted" shares under the Securities Act. On the date of this Prospectus,
no shares other than the          shares offered hereby will be eligible for
sale. Upon the expiration of lock-up agreements 180 days after the date of
this Prospectus, an additional 16,668,509 shares will become eligible for sale
in the public market, subject in the case of all but 2,661,052 shares to the
volume limitations and other conditions of Rule 144 adopted under the
Securities Act ("Rule 144"). The remaining 350,000 shares will become eligible
for sale in November 1998, subject to the volume limitations and other
conditions of Rule 144. In addition, the Company intends to file a
registration statement on Form S-8 with the Securities and Exchange Commission
shortly after this offering covering (i) the 2,625,000 shares of Common Stock
reserved or to be reserved for issuance under the Company's Equity Incentive
Plan, Purchase Plan and Directors Plan, (ii) an additional number of shares of
Common Stock to be reserved for issuance under the Equity Incentive Plan equal
to the number of shares reserved for future issuance under the 1995 Stock
Option Plan and 1997 Stock Option Plan as of the date of this Prospectus
(717,482 as of October 31, 1997), and (iii) the shares subject to outstanding
options granted under the Company's 1995 Stock Option Plan and 1997 Stock
Option Plan as of the date of this Prospectus (2,362,528 as of October 31,
1997). The holders of approximately 14,719,339 shares of Common Stock are also
entitled to certain rights with respect to registration of such shares of
Common Stock for offer or sale to the public. If such holders, by exercising
their registration rights, cause a large number of shares to be registered and
sold in the public market, such sales could have a material adverse effect on
the market price for the Company's Common Stock. See "Management--Director
Compensation," "--Employee Benefit Plans," "Description of Capital Stock--
Registration Rights" and "Shares Eligible for Future Sale."     
 
  Acquisitions. The Company from time to time may acquire or invest in
businesses, technologies and product lines that are complementary to the
Company's business. Although the Company currently has no understandings,
commitments or agreements with respect to any acquisitions, any such
acquisitions would be accompanied by the risks commonly encountered in such
transactions, including, among others, the difficulty of assimilating the
operations and personnel of the acquired businesses, the potential disruption
of the Company's ongoing business, the diversion of the Company's management
from the day-to-day operations of the Company, the inability of the Company to
incorporate acquired technologies successfully into the Company's products and
services, the additional expense associated with amortization of acquired
intangible assets, the potential impairment of the Company's relationships
with its employees, customers and strategic partners, the inability of the
Company to retain key technical and managerial personnel of the acquired
business and the inability of the Company to maintain uniform standards,
controls, procedures and policies. Because of these and other factors, any
such acquisitions, if consummated, could have a material adverse affect on the
Company's business, operating results and financial condition. See "Use of
Proceeds."
 
  No Prior Trading Market; Possible Volatility of Stock Price. Prior to this
offering, there has been no public market for the Common Stock of the Company
and there can be no assurance that an active trading market will develop or be
sustained upon completion of this offering. The initial public offering price,
which will be established by negotiations between the Company and the
representatives of the Underwriters based upon a number of factors, may not be
indicative of prices that will prevail in the trading market. See
"Underwriters" for a discussion of the factors to be considered in determining
the initial public offering price. The stock market from time to time has
experienced significant price and volume fluctuations. In addition, the market
prices of securities of other technology companies, particularly Internet-
related companies, have been highly volatile. Factors such as fluctuations in
the Company's operating results, announcements of technological innovations or
new products or services by the Company or its competitors, analysts' reports
and projections, regulatory actions and general market conditions may have a
significant effect on the market price of the Company's Common Stock. See
"Underwriters."

  Control by Existing Stockholders. Upon completion of this offering, the
present executive officers, directors and 5% stockholders of the Company and
their affiliates will beneficially own approximately   % of the Company's
outstanding Common Stock (  % if the Underwriters' over-allotment option is
exercised in full). As a result, these stockholders would be able to
significantly influence the management and affairs of the Company and all
matters requiring stockholder approval, including the election of directors
and approval of significant corporate transactions such as a merger,
consolidation or sale of substantially all of the Company's assets. Such
concentration of ownership might have the effect of delaying or preventing a
change in control of the Company and might affect the market price of the
Company's Common Stock and the voting and other rights of the Company's other
stockholders. See "Principal Stockholders."
 
  Immediate and Substantial Dilution. Investors participating in this offering
will incur immediate, substantial dilution in the amount of $    per share. To
the extent that outstanding options to purchase the Company's Common Stock are
exercised, there will be further dilution. See "Dilution."
 
  Unspecified Use of Proceeds. The Company plans to use substantially all of
the net proceeds from this offering for general corporate purposes, including
working capital and capital expenditures. The Company may also use a portion
of the net proceeds from this offering to acquire or invest in businesses,
technologies and product lines that are complementary to the Company's
business. The Company has no present plans or commitments and is not currently
engaged in any negotiations with respect to such transactions. As a result,
the Company will have significant discretion as to the use of the net proceeds
from this offering. Pending such uses, the Company intends to invest the net
proceeds from this offering in short-term, interest-bearing, investment-grade

                                USE OF PROCEEDS
 
  The net proceeds to the Company from the sale of the             shares of
Common Stock offered by the Company hereby are estimated to be approximately
$       million (approximately $       million if the Underwriters' over-
allotment option is exercised in full), at an assumed initial public offering
price of $     per share and after deducting estimated underwriting discounts
and commissions and estimated offering expenses payable by the Company. The
primary purposes of this offering are to obtain additional equity capital,
create a public market for the Company's Common Stock and facilitate future
access by the Company to the public equity markets.
 
  The Company intends to use approximately $5.0 million of the net proceeds of
this offering to fund its capital expenditures for 1998 and to utilize the
remainder of the net proceeds of this offering primarily for general corporate
purposes, including working capital. The Company may also use a portion of the
net proceeds from this offering to acquire or invest in businesses,
technologies and product lines that are complementary to the Company's
business. The Company has no present plans or commitments and is not currently
engaged in any negotiations with respect to such transactions. As a result,
the Company will have significant discretion as to the use of the net proceeds
from this offering. Pending such uses, the Company intends to invest the net
proceeds from this offering in short-term, interest-bearing, investment-grade
securities. See "Risk Factors--Acquisitions" and "--Unspecified Use of
Proceeds."
 
                                DIVIDEND POLICY
 
  The Company has never declared or paid any cash dividends on its Common
Stock or other securities and does not anticipate paying any cash dividends in
the foreseeable future. In addition, the terms of the Company's equipment line
of credit agreement prohibit the payment of dividends on its capital stock.

claims of VeriFone, and (iii) on a pro forma as adjusted basis to reflect the
receipt by the Company of the estimated net proceeds from the sale of the
        shares of Common Stock offered by the Company hereby at an assumed
initial public offering price of $     per share and after deducting estimated
underwriting discounts and commissions and estimated offering expenses payable
by the Company.

                                   DILUTION
   
  The pro forma net tangible book value of the Company's Common Stock as of
September 30, 1997 was $17.9 million, or $1.06 per share. Pro forma net
tangible book value per share is equal to the Company's total tangible assets
less its total liabilities, divided by the pro forma shares of Common Stock
outstanding as of September 30, 1997. After giving effect to the issuance and
sale of the             shares of Common Stock offered by the Company hereby
(at an assumed initial public offering price of $     per share and after
deducting estimated underwriting discounts and commissions and estimated
offering expenses payable by the Company), the Company's as adjusted net
tangible book value as of September 30, 1997 would have been $           , or
$      per share. This represents an immediate increase in pro forma net
tangible book value of $     per share to existing stockholders and an
immediate dilution of $      per share to new public investors. The following
table illustrates the per share dilution:

                     MANAGEMENT'S DISCUSSION AND ANALYSIS
               OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
  The following discussion should be read in conjunction with the Consolidated
Financial Statements and notes thereto appearing elsewhere in this Prospectus.
The following discussion contains forward-looking statements. The Company's
actual results may differ significantly from those projected in the forward-
looking statements. Factors that might cause future results to differ
materially from those projected in the forward-looking statements include, but
are not limited to, those discussed in "Risk Factors" and elsewhere in this
Prospectus.
 
OVERVIEW
   
  VeriSign is the leading provider of digital certificate solutions and
infrastructure needed by companies, government agencies, trading partners and
individuals to conduct trusted and secure communications and commerce over IP
networks. The Company's Digital IDs are enabled in millions of copies of
Microsoft and Netscape Web browsers, tens of thousands of copies of popular
Web servers and a variety of other software applications. The Company believes
that it has issued more digital certificates than any other company, having
issued over 1.5 million of its Digital IDs for individuals and over 35,000 of
its Digital IDs to organizations, primarily businesses, for their Web sites.
Because the Company has issued most of its Digital IDs for individuals on a
trial or promotional basis, a significant majority of the Company's revenues
to date have been derived from businesses.     
   
  The Company was incorporated in April 1995 and introduced its first product,
the Secure Server ID for Netscape Commerce Servers, in June 1995. In October
1995, the Company introduced additional Server Digital IDs for the Web server
products of Microsoft, IBM, Open Market and other vendors. In May 1996, the
Company began providing online enrollment and issuance of client Digital IDs
for Netscape Navigator through its Digital ID Center and began shipping
another form of Digital ID known as a Software Developer Digital ID for
Microsoft's Authenticode program. The Company began issuing Digital IDs for
Microsoft's Internet Explorer through the Company's Digital ID Center in
August 1996. During 1997, the Company introduced its Universal Digital IDs and
three new types of server digital certificate products--its Global Server ID,
Financial Server ID and EDI Server ID.     
 
  In April 1996, the Company entered the enterprise and electronic commerce
markets by introducing custom SET digital certificate solutions targeted at
certified banks, payment processors and major card brands. During 1997, the
Company introduced VeriSign OnSite and VeriSign V-Commerce, which are
enterprise and electronic commerce digital certificate solutions that are
targeted at mid-sized to large companies, managed intranets and extranets,
payment card industry service providers and Web sites with large customer or
user bases. During 1997, the Company began providing technology and products
for digital certificate management to OEMs.
   
  Historically, the Company has derived substantially all of its revenues from
the sale of Digital IDs and from fees for services rendered in connection with
the Company's digital certificate solutions and digital certificate service
and product development agreements. Sales of Digital IDs and fees for services
each resulted in approximately one-half of the Company's revenues in 1997. The
purchase of a Digital ID allows the customer to use the Digital ID for a
limited period of time, generally 12 months. After this period, the Digital ID
must be renewed for continued usage by the customer. Renewal fees are
typically lower than the fees charged for the initial Digital ID. Revenues
from the sale or renewal of Digital IDs are deferred and recognized ratably
over the life of the digital certificate. Revenues from the Company's
enterprise and electronic commerce solutions consist of fees for the issuance
of digital certificates, which are recognized ratably over the term of the
particular license agreement relating to the enterprise or electronic commerce
solution, and fees for set-up services, which are recognized upon completion
of the service. Revenues from other services are recognized using the
percentage-of-completion method for fixed-fee development arrangements, on a
time-and-materials basis for consulting and training services or ratably over
the term of the agreement for support and maintenance services. Deferred
revenues increased from $46,000 at December 31, 1995 to $1.9 million at
December 31, 1996 and to $3.1 million at September 30, 1997. In the future,
the Company anticipates that it may receive additional revenues from sales
    
                                      22
<PAGE>
 
of software products and value-added services, licensing and royalty fees from
licenses of digital certificates and related technology and maintenance, and
fees for customer support services.
       
       
  The Company markets its products and services worldwide through multiple
distribution channels, including the Internet, direct sales, telesales, VARs,
systems integrators and OEMs. Although a significant portion of its revenues
to date has been generated through sales from the Company's Web site, the
Company intends to increase its direct sales force, both domestically and
internationally, and intends to continue to expand its other distribution
channels.
   
  In February 1996, the Company formed VeriSign Japan to provide digital
certificate solutions to the Japanese market. In connection with the formation
of this subsidiary, the Company licensed certain technology and contributed
other assets to VeriSign Japan. Subsequent to its formation, additional
investors purchased minority interests in VeriSign Japan, and, as of September
30, 1997, the Company owned 51% of the outstanding capital stock of VeriSign
Japan. Accordingly, the Company's consolidated financial statements include
the accounts of the Company and this subsidiary and the Company's consolidated
statements of operations reflect the elimination of the minority shareholders'
share of the net losses of the subsidiary. Historically, VeriSign Japan has
funded its net losses with investments from minority shareholders. However, to
the extent VeriSign Japan is unable to continue to fund its operations
principally from investments by minority shareholders, the Company may be
required to fund the operations of this subsidiary, which could have a
material adverse effect on the Company's business, operating results and
financial condition. See "Business--VeriSign Japan."     
 
  The Company has experienced substantial net losses in each fiscal period
since its inception and, as of September 30, 1997, had an accumulated deficit
of $25.0 million. Such net losses and accumulated deficit resulted from the
Company's lack of substantial revenues and the significant costs incurred in
the development and sale of the Company's products and services and in the
establishment and deployment of the Company's operations infrastructure and
practices. The Company intends to increase its expenditures in all areas in
order to execute its business plan. As a result, the Company expects to incur
substantial additional losses for the foreseeable future. Although the Company
has experienced revenue growth in recent periods, there can be no assurance
that such growth rates are sustainable and, therefore, they should not be
considered indicative of future operating results. There can be no assurance
that the Company will ever achieve significant revenues or profitability or,
if significant revenues and profitability are achieved, that they could be
sustained. See "Risk Factors--Limited Operating History; History of Losses and
Anticipation of Future Losses."
 
RESULTS OF OPERATIONS
 
  REVENUES
 
  The Company's revenues increased from $382,000 for the period from April 12,
1995 (inception) to December 31, 1995 (the "Inception Period") to $1.4 million
for 1996 and to $6.1 million for the nine months ended September 30, 1997.
Revenues from inception through December 31, 1996 were primarily derived from
sales of the Company's Server Digital ID products. The increase in revenues
from the Inception Period to 1996 was due primarily to increased market
acceptance of Server Digital IDs and, to a lesser extent, SET digital
certificate solutions. The increase in revenues from 1996 to the nine months
ended September 30, 1997 was due primarily to increased sales of Server
Digital IDs and to increased services revenues, which included revenues from
digital certificate service and product development agreements. Revenues from
the sale of Universal Digital IDs have been nominal because substantially all
of the Company's Universal Digital IDs have been issued free of charge on a
promotional basis.
 
  Revenues attributable to VISA accounted for approximately 21% and 16% of
revenues for 1996 and for the nine months ended September 30, 1997,
respectively. No other customer accounted for more than 10% of the Company's
revenues during the Inception Period, 1996 or the nine months ended September
30, 1997. Revenues of VeriSign Japan and revenues from other international
customers accounted for less than 10% of revenues for the Inception Period and
1996 and approximately 15% of revenues for the nine months ended September 30,
1997.

  COSTS AND EXPENSES
 
  The Company's costs and expenses have increased in absolute dollars since
inception, primarily due to the overall growth of the Company. The total
number of the Company's employees increased from 30 at December 31, 1995 to
162 at September 30, 1997. In addition, the Company opened several new
offices, increased its sales and marketing and research and development
efforts, and expanded its headquarters and Digital ID Centers during this
period. The Company believes that it will need to continue to expand its
operations in order to execute its business strategy. Accordingly, the Company
intends to continue to increase its costs and expenses in all areas for the
foreseeable future.
 
  Cost of Revenues. Cost of revenues consists primarily of costs related to
personnel providing digital certificate enrollment and issuance services,
customer support and training, consulting and development services, and
facilities and computer equipment used in such activities. Cost of revenues
also includes fees paid to third parties to verify certificate applicants'
identities and insurance premiums for the Company's NetSure warranty plan and
errors and omission insurance. Cost of revenues increased from $412,000 for
the Inception Period to $2.8 million for 1996 and to $5.2 million for the nine
months ended September 30, 1997. Cost of revenues was not material during the
Inception Period as a result of the Company's minimal revenues. The increases
in 1996 and the nine months ended September 30, 1997 were due primarily to
increased facilities costs and related overhead that resulted from building
the Company's operations infrastructure, hiring full-time and temporary
personnel to support the additional volume of issuances of Server Digital IDs,
introduction of additional Server Digital ID products, introduction of the
Company's NetSure warranty program, increased costs of errors and omission
insurance, increased expenses for access to third-party databases and, during
1997, implementation of the Company's disaster recovery plan. Given the
Company's limited operating history, limited history of issuing Digital IDs
and evolving industry and business model, the Company believes that analysis
of cost of revenues as a percentage of revenues is not yet meaningful.
 
  Sales and Marketing. Sales and marketing expenses consist primarily of costs
related to sales, marketing and practices and external affairs personnel,
including salaries, sales commissions and other personnel-related expenses,
computer equipment and support services used in such activities, facilities
costs, consulting fees and costs of marketing programs. Sales and marketing
expenses increased from $790,000 for the Inception Period to $4.9 million for
1996 and to $7.3 million for the nine months ended September 30, 1997. These
increases were due primarily to increased headcount and, to a lesser extent,
increased expenditures for marketing programs. The Company anticipates that
sales and marketing expenses will continue to increase in absolute dollars as
it expands its direct sales force, hires additional marketing personnel and
increases its marketing and promotional activities during 1998. In addition,
the Company expects to record, during the fourth quarter of 1997, an $800,000
charge resulting from the issuance of 100,000 shares of Common Stock to
Microsoft in connection with a preferred provider agreement.
 
                                      24
<PAGE>
 
  Research and Development. Research and development expenses consist
primarily of costs related to research and development personnel, including
salaries and other personnel-related expenses, consulting fees, facilities,
and computer equipment and support services used in product and technology
development. Research and development expenses increased from $642,000 for the
Inception Period to $2.1 million for 1996 and to $3.6 million for the nine
months ended September 30, 1997. These increases were due primarily to
increased personnel to support the design, testing and deployment of, and
technical support for, the Company's expanded product offerings and
technology. The Company believes that timely development of new and enhanced
products and technology are necessary to remain competitive in the
marketplace. Accordingly, the Company intends to continue recruiting and
hiring experienced research and development personnel and make other
investments in research and development. Therefore, the Company expects that
research and development expenditures will continue to increase in absolute
dollars. To date, all research and development expenses have been expensed as
incurred.
 
  General and Administrative. General and administrative expenses consist
primarily of salaries and other personnel-related expenses for the Company's
administrative, finance and human resources personnel, facilities and computer
equipment, support services and professional services fees. General and
administrative expenses increased from $680,000 for the Inception Period to
$2.6 million for 1996 and $2.9 million for the nine months ended September 30,
1997. These increases were due primarily to increased staffing levels to
manage and support the Company's expanding operations. The Company anticipates
hiring additional personnel and incurring additional costs related to being a
public company, including directors' and officers' liability insurance,
investor relations programs and professional services fees. Accordingly, the
Company anticipates that general and administrative expenses will continue to
increase in absolute dollars.
 
  Litigation Settlement. In September 1996, VeriFone, which subsequently became
a wholly-owned subsidiary of Hewlett-Packard Company ("Hewlett-Packard"), filed
a lawsuit against the Company alleging, among other things, trademark
infringement. In November 1997, the parties executed a definitive agreement
under which, among other things, the Company issued an aggregate of 250,000
shares of Common Stock, which were transferred to Hewlett-Packard, and the
Company and VeriFone settled such claims. The settlement amount was recorded
during the nine months ended September 30, 1997 as a charge of $2.0 million.
 
  OTHER INCOME (EXPENSE)
 
  Other income (expense) consists primarily of interest earned on the
Company's cash, cash equivalents and short-term investments, less interest
expense on bank borrowings of VeriSign Japan and the effect of foreign
currency transaction gains and losses. The Company had other income of
$148,000 for the Inception Period, other expense of $67,000 for 1996 and other
income of $860,000 for the nine months ended September 30, 1997. The increase
for the nine months ended September 30, 1997 was due to interest earned on the
cash proceeds from the Company's November 1996 Series C Preferred Stock
financing.
 
  INCOME TAXES
 
  No provision for federal and California income taxes has been recorded
because the Company has experienced net losses since inception. As of
September 30, 1997, the Company had federal and California net operating loss
carryforwards of approximately $10.5 million in each jurisdiction. These
federal and California net operating loss carryforwards will expire, if not
utilized, in years 2010 through 2012 and in years 2000 through 2003,
respectively. The Tax Reform Act of 1986 imposes substantial restrictions on
the utilization of net operating losses and tax credits in the event of an
"ownership change" of a corporation. The Company's ability to utilize net
operating loss carryforwards may be limited as a result of an "ownership
change" as defined in the Internal Revenue Code. The Company does not
anticipate that a material limitation on its ability to use such carryforwards
and credits will result from this offering. The Company has provided a full
valuation allowance on the deferred tax asset because of the uncertainty
regarding its realization. The Company's accounting for deferred taxes under
Statement of Financial Accounting Standards No. 109 involves the evaluation of
a number of factors concerning the realizability of the Company's deferred tax
assets. In concluding that a full valuation allowance was required, management
primarily considered such factors as the Company's history of operating
 
                                      25
<PAGE>
 
losses and expected future losses and the nature of the Company's deferred tax
assets. Although management's operating plans assume taxable and operating
income in future periods, management's evaluation of all the available
evidence in assessing the realizability of the deferred tax assets indicates
that such plans were not considered sufficient to overcome the available
negative evidence. See Note 7 of Notes to Consolidated Financial Statements.
 
  MINORITY INTEREST IN NET LOSS OF SUBSIDIARY
 
  Minority interest in the net losses of VeriSign Japan was $838,000 for 1996
and $1.2 million for the nine months ended September 30, 1997. This increase
was due to the increased expenses incurred in establishing and expanding the
operations of VeriSign Japan prior to recognizing significant revenues and to
an increasing percentage of VeriSign Japan's capital stock being held by
minority shareholders. VeriSign Japan is still in an early stage of operations
and, therefore, the Company expects that the minority interest in net loss of
subsidiary will continue to fluctuate in future periods.
 
SELECTED QUARTERLY OPERATING RESULTS
 
  The following table sets forth certain consolidated statement of operations
data for each quarter of 1996 and the first three quarters of 1997. This
information has been derived from the Company's unaudited consolidated
financial statements, which, in management's opinion, have been prepared on
the same basis as the annual consolidated financial statements and include all
adjustments, consisting only of normal recurring adjustments, necessary for a
fair presentation of the information for the quarters presented. This
information should be read in conjunction with the Consolidated Financial
Statements and notes thereto included elsewhere in this Prospectus. The
operating results for any quarter are not necessarily indicative of the
results for any future period.

  REVENUES
 
  The Company has experienced quarter-to-quarter sequential growth in revenues
since its inception. These quarterly increases were due primarily to the
increased number of Server Digital IDs sold during these periods. In addition,
during the first quarter of 1997, the Company completed certain work required
under various certificate service and product development agreements and,
therefore, recognized the related portion of revenues during that quarter. The
Company realized additional services fees during the second quarter of 1997 as
a result
 
                                      26
<PAGE>
 
of entering into new certificate service and product development agreements
and completing work under existing certificate service and product development
agreements. During the third quarter of 1997, revenues attributable to digital
certificates grew as a result of the increased number of digital certificates
sold and an approximately 15% per unit price increase. Revenues also increased
in the third quarter of 1997 as a result of the completion of work under other
certificate service and product development agreements.
 
  COSTS AND EXPENSES
 
  Cost of Revenues. Throughout 1996, the Company was developing a secure
operations and customer support infrastructure as well as related systems.
During the fourth quarter of 1996, the Company began building its new Digital
ID Center to manage enrollment and issuance of large volumes of Digital IDs
and moved its customer support and information systems teams into the new
Digital ID Center. Accordingly, facilities costs and related overhead
increased significantly in the first quarter of 1997. During the second and
third quarters of 1997, the Company added full-time and temporary personnel,
particularly for customer support and information systems, in order to support
the additional volume of issuances of Server Digital IDs. The Company also
devoted additional personnel resources to support work under the Company's
product development agreements during this time period. During the second
quarter of 1997, the Company introduced its NetSure warranty program,
resulting in higher insurance premiums. During the third quarter of 1997, the
Company also incurred increased expenses for access to third-party databases
to verify certificate applicants' identities and expenses relating to the
implementation of the Company's disaster recovery plan.
 
  Sales and Marketing. The quarterly increases in sales and marketing expenses
resulted primarily from the building of the Company's sales and marketing
organization, which began in 1996. During the third and fourth quarters of
1996, the Company began expanding its marketing organization to include
corporate, channel and product marketing programs. In each of the first three
quarters of 1997, the Company added sales and marketing personnel to support
its expanding product lines, which resulted in higher recruiting, benefits,
travel and facilities costs. Sales and marketing expenses were higher in the
second quarter of 1997 than the preceding two quarters and the following
quarter due to increased expenses incurred pursuing international and domestic
strategic relationships, increased public relations activities, Web site
management costs and channel development activities.
 
  Research and Development. The sequential quarterly increases in research and
development expenses were due primarily to increased personnel and related
costs to support the design, testing and deployment of, and technical support
for, the Company's expanded product offerings and technology.
 
  General and Administrative. The sequential quarterly increases in general
and administrative expenses over the four quarters of 1996 were primarily
related to the addition of personnel and related costs to support expansion of
the Company's operations. During the fourth quarter of 1996, the Company
incurred additional expenses for consulting services, increased legal fees
relating to a large number of contract negotiations and increased expenses
resulting from a growth in headcount. During the fourth quarter of 1996 and
into 1997, the Company incurred increased expenses for a larger facility and
for the implementation of additional systems and procedures.
 
FACTORS AFFECTING OPERATING RESULTS
 
  The Company's operating results have varied on a quarterly basis during its
short operating history and may fluctuate significantly in the future as a
result of a variety of factors, many of which are outside the Company's
control. Factors that may affect the Company's quarterly operating results
include the following: market acceptance of digital certificates; market
acceptance of its products and services, particularly VeriSign OnSite,
VeriSign V-Commerce and VeriSign SET; the long sales and implementation cycles
for and potentially large order sizes of certain of the Company's products and
services; the timing and execution of individual contracts; the timing of
releases of new versions of Internet browsers or other third-party software
products in which the Company's public root keys are embedded; customer
renewal rates for the Company's products and services;
 
                                      27
<PAGE>
 
the Company's success in marketing other products and services to its existing
customer base and to new customers; development of the Company's direct and
indirect distribution channels; market acceptance of the Company's or
competitors' new products and services; the amount and timing of expenditures
relating to expansion of the Company's operations; price competition or
pricing changes; general economic conditions and economic conditions specific
to the Internet, intranet and extranet industries. Any one of these factors
could cause the Company's revenues and operating results to vary significantly
in the future. In addition, the Company will need to expand its operations and
attract, integrate, retain and motivate a substantial number of sales and
marketing and research and development personnel. The timing of such expansion
and the rate at which new personnel become productive could cause material
fluctuations in the Company's quarterly operating results.
 
  The Company's limited operating history and the emerging nature of its
market make prediction of future revenues difficult. The Company's expense
levels are based, in part, on its expectations regarding future revenues, and
to a large extent such expenses are fixed, particularly in the short term.
There can be no assurance that the Company will be able to predict its future
revenues accurately and the Company may be unable to adjust spending in a
timely manner to compensate for any unexpected revenue shortfall. Accordingly,
any significant shortfall of revenue in relation to the Company's expectations
could cause significant declines in the Company's quarterly operating results.
 
  Due to all of the foregoing factors, the Company's quarterly revenues and
operating results are difficult to forecast. The Company believes that period-
to-period comparisons of its operating results will not necessarily be
meaningful and should not be relied upon as an indication of future
performance. Also, it is likely that the Company's operating results will fall
below the expectations of the Company, securities analysts or investors in
some future quarter. In such event, the market price of the Company's Common
Stock could be materially and adversely affected.
 
LIQUIDITY AND CAPITAL RESOURCES
 
  Since inception, the Company has financed its operations primarily through
private sales of equity securities raising approximately $42.7 million. At
September 30, 1997, the principal source of liquidity for the Company was
$13.6 million of cash, cash equivalents and short-term investments. The
Company also has an equipment loan agreement under which it may borrow up to
$3.0 million for purchases of equipment. This equipment loan agreement expires
on March 31, 1999. Any amounts borrowed under this equipment loan agreement
would bear interest at the rate of 7.5% per annum and would be secured by the
equipment purchased with the loan proceeds. In the event that the Company
borrows under this equipment loan agreement, it will be obligated to issue to
the lender a warrant to purchase 17,500 shares of Common Stock. The Company
currently has no plans to borrow any amounts under this equipment loan
agreement.
 
  VeriSign Japan has an available credit facility of 250,000,000 yen
(approximately $2.1 million as of September 30, 1997) with a bank, which bears
interest at a rate of 1.625% per annum and expires in January 1998. At
September 30, 1997, VeriSign Japan had borrowed approximately $1.5 million
under this facility, which borrowings were secured by certain assets of
VeriSign Japan. VeriSign Japan also has available a revolving line of credit
of up to $500,000 with a bank that bears interest at 1.625% per annum and
expires in April 1998. The line of credit is secured by a letter of credit
from the Company in the same amount. There were no borrowings outstanding
under this line of credit as of September 30, 1997.
 
  The Company has had significant negative cash flows from operating
activities in each fiscal period to date. Net cash used in operating
activities for the Inception Period, 1996 and the nine months ended
September 30, 1997 was $1.5 million, $6.0 million and $11.8 million,
respectively. Net cash used in operating activities in each of these periods
was primarily the result of net losses, offset in part by increases in
accounts payable and accrued liabilities for the Inception Period and 1996 and
deferred revenues in all three fiscal periods.
 
  Net cash used in investing activities for the Inception Period, 1996 and the
nine months ended September 30, 1997 was $1.0 million, $4.4 million and $13.5
million, respectively. Net cash used in investing
 
                                      28
<PAGE>
 
activities in these periods was primarily the result of capital expenditures
for computer equipment, purchased software, office equipment, furniture,
fixtures and leasehold improvements. In addition, for the nine months ended
September 30, 1997, cash used in investing activities included $7.7 million of
net purchases of short-term investments. Capital expenditures for property and
equipment for the Inception Period, 1996 and the nine months ended September
30, 1997 aggregated $1.0 million, $4.2 million and $5.3 million, respectively.
The Company's planned capital expenditures for the fourth quarter of 1997 and
for 1998 are approximately $1.2 million and $5.0 million, respectively,
primarily for computer equipment and other leasehold improvements. As of
September 30, 1997, the Company also had commitments under noncancelable
operating leases of $6.7 million through 2002.
 
  Cash provided by financing activities for the Inception Period, 1996 and the
nine months ended September 30, 1997, was $5.3 million, $37.8 million and $1.3
million, respectively, resulting primarily from net proceeds from the sale of
Preferred Stock by the Company. In addition, for 1996 and the nine months
ended September 30, 1997, cash provided by financing activities of VeriSign
Japan was $4.4 million and $1.2 million, respectively, resulting from the sale
of its capital stock to minority investors and from the proceeds of its bank
borrowings.
 
  The Company believes that the net proceeds from this offering, together with
existing cash, cash equivalents and short-term investments, will be sufficient
to meet its working capital and capital expenditure requirements for at least
the next 12 months. The Company may need to raise additional funds through
public or private financing, strategic relationships or other arrangements.
There can be no assurance that such additional funding, if needed, will be
available on terms attractive to the Company, or at all. Strategic
relationships, if necessary to raise additional funds, may require the Company
to relinquish rights to certain of its technologies or products. The failure
of the Company to raise capital when needed could have a material adverse
effect on the Company's business, operating results and financial condition.
If additional funds are raised through the issuance of equity securities, the
percentage ownership of the Company of its then-current shareholders would be
reduced. Furthermore, such equity securities might have rights, preferences or
privileges senior to those of the Company's Common Stock. See "Risk Factors--
Future Capital Needs; Uncertainty of Additional Financing."
 
RECENT ACCOUNTING PRONOUNCEMENTS
 
  In February 1997, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards ("SFAS") No. 128, Earnings Per Share, which
adjusts the calculation of earnings per share under generally accepted
accounting principles. SFAS No. 128 must be adopted by the Company during the
first quarter of 1998. See Note 1 of Notes to Consolidated Financial
Statements for the effect of SFAS No. 128 on the Company's pro forma net loss
per share presentation.
 
  In October 1997, the American Institute of Certified Public Accountants
issued Statement of Position ("SOP") No. 97-2, Software Revenue Recognition,
which supersedes SOP No. 91-1. The Company will be required to adopt SOP No.
97-2 prospectively for software transactions entered into beginning January 1,
1998. SOP No. 97-2 generally requires revenue earned on software arrangements
involving multiple elements to be allocated to each element based on the
relative fair values of the elements. The fair value of an element must be
based on evidence that is specific to the vendor. If a vendor does not have
evidence of the fair value for all elements in a multiple-element arrangement,
all revenue from the arrangement is deferred until such evidence exists or
until all elements are delivered. The Company's management anticipates that
the adoption of SOP No. 97-2 will not have a material effect on the Company's
operating results.

INDUSTRY BACKGROUND
 
  GROWTH OF INTERNET COMMERCE AND COMMUNICATIONS
 
  IP networks are revolutionizing the ways in which companies, government
agencies, trading partners and individuals communicate and conduct business.
IP networks provide an attractive medium for communications and commerce
because of their global reach, accessibility, use of open standards and
ability to enable real-time interaction. Organizations are seeking to leverage
the capabilities of IP networks to attract new customers, access new markets,
improve customer service and satisfaction and lower support and distribution
costs. Until recently, IP networks have been used primarily for informal
messaging, general information browsing and the exchange of non-sensitive
data. The use of IP networks is now beginning to extend beyond these initial
uses to a number of more valuable and sensitive activities, including
business-to-business transactions and Internet-based EDI, online retail
purchases and payments, Web-based access to account and benefits information
and secure messaging for both personal and business use. Forrester Research
estimates that Internet business-to-business commerce alone will grow from
less than $8 billion in 1997 to more than $327 billion in 2002.
 
  REQUIREMENT FOR TRUSTED INTERACTION OVER IP NETWORKS
 
  Although openness represents a fundamental strength of IP networks, their
accessibility and the anonymity of users resulting from the lack of "face-to-
face" interaction create threats to the privacy and integrity of information
that is transmitted across or stored on these networks. Despite the
convenience and the compelling economic incentives for the use of IP networks,
they cannot reach their full potential as a platform for global communications
and commerce until the current lack of security and trust associated with
these networks is resolved. According to a study conducted in 1997 by Zona
Research, Inc., 70% of the businesses and consumers surveyed listed concerns
about trust and security as the main impediment to broader use of the Internet
for commercial applications. Business concerns include the potential for theft
of corporate or customer information, impersonation of employees, loss of
reputation and economic loss through fraud. Consumer concerns include the
possibility of merchant impersonation and fraud and the risk that third
parties may be able to intercept and use personal information such as credit
card numbers. Traditional security mechanisms such as passwords and personal
identification numbers do not adequately address these issues, as they can be
easily lost, forgotten or misappropriated. Some security concerns are being
addressed through technologies such as encryption and firewalls, but these
technologies do not address the need to establish and maintain a common
framework of trust between parties conducting transactions or exchanging
sensitive information in the digital world.
 
                                      30

  In the physical world, trust in communications and commerce is established
through a combination of social, business and legal practices that, in some
cases, have been developed over hundreds of years. These practices often
include the use of physical credentials, such as credit cards, business
licenses or employee badges, and the associated legal protections to avoid
loss from theft or fraud. The diligence, practices, policies and reputations
of the organizations standing behind the issuance, delivery, revocation and
renewal of physical credentials provide a readily understood and accepted
framework of trust for a given communication or transaction. The physical
credentials that embody these proven practices and frameworks of trust and the
social interactions that accompany their use cannot be utilized in the digital
world. As a result, there is a need for a trusted and convenient way to verify
the identity, authority and privilege of the parties involved in
communications and commerce over IP networks and to assure their proper and
trusted association with a specific organization or community.
 
  EMERGENCE OF DIGITAL CERTIFICATE TECHNOLOGY
 
  Digital certificates are emerging as the leading technology for establishing
a framework for trusted and secure communications and commerce over IP
networks, with many Internet security protocols dictating the use of digital
certificates. A digital certificate is a specially prepared software file that
functions as an electronic credential in the digital world, identifying the
certificate owner, authenticating the certificate owner's membership in a
given organization or community (credit card holder, employee, supply chain
participant or citizen) and establishing the certificate owner's authority to
engage in a given transaction. Utilizing the principles of public key
cryptography, a digital certificate binds a pair of unique mathematical keys,
one designated as "private" and securely maintained by its owner, and the
other designated as "public" and embedded in the digital certificate. What the
owner's private key digitally signs, only the corresponding public key can
verify. When properly prepared, issued and administered, digital certificates
create a framework for trusted interaction over IP networks, making it
possible, for example, to verify with certainty the identity of an account
holder or a Web-based business, the source of an electronic message or the
integrity of electronically distributed software or content.
 
  Significant efforts are underway to utilize digital certificates as
"vehicles of trust" for securely transmitting e-mail, accessing information on
public and private Web sites, purchasing retail goods and services and
conducting other financial transactions such as electronic securities trading.
The leading vendors of Web browser, Web server, electronic mail, electronic
payment and content distribution applications have incorporated digital
certificate technology as the framework for establishing trusted and secure
communications and commerce over IP networks and are embedding support for
digital certificates in their products. A number of standard protocols that
are being widely adopted for communications and commerce require the use of
digital certificates. These protocols include the Secure Sockets Layer
protocol ("SSL") for browser/server authentication and secure data
transmission, the Secure Multipurpose Internet Mail Extensions protocol
("S/MIME") for secure e-mail and EDI, the Secure Electronic Transactions
protocol ("SET") for secure electronic payments, and the Internet Protocol
Security standard ("IP/SEC") for authentication of networking devices. Just as
an individual may have many forms of credit cards and IDs, he or she may
require multiple digital certificates, each corresponding to a unique digital
relationship between the individual and an organization. Thus, there is the
potential need over time for hundreds of millions of digital certificates to
be issued and managed.
 
  CERTIFICATION AUTHORITIES AND THE NEED FOR TRUSTED INFRASTRUCTURE
 
  Digital certificates are prepared and managed by trusted parties known as
Certification Authorities ("CAs"). To prepare a digital certificate for
issuance, a CA embeds an individual's or an organization's public key along
with specific personal information (name or e-mail address) or organizational
information (domain name or affiliation) in the digital certificate, which is
then cryptographically "signed" by the CA. The CA's digital signature acts as
a tamper-proof electronic seal that verifies the integrity of the information
within the digital certificate and validates its use within a specific
organization or community. This digital signature is linked to the CA's public
"root key," which is embedded in the browser, server or other application used
by the
 
                                      31
<PAGE>
 
organization or community. Through the embedded public root key, a community
member can automatically confirm the authenticity of a digital certificate--
and hence the certificate owner's identity, authority and privilege--to verify
the source and integrity of any accompanying message or transaction request.
 
  A CA may digitally sign certificates for multiple organizations or
communities, each having different rules, qualifications or procedures
governing the admission of members. The CA may sign and issue certificates
directly to the members of a given community or sign certificates on behalf of
other entities (credit card issuers, corporations or government agencies) that
wish to control the admission of members into their organizations and grant to
them certain authority and privileges.
 
  The successful implementation and management of digital certificates as a
mechanism for trusted and secure commerce and communications present a number
of issues and challenges for a CA. The CA must establish and maintain rigorous
practices, policies and procedures to manage the technical complexities of
cryptographic key management and provide for the secure creation and
distribution of digital certificates. The CA must carefully manage the entire
lifecycle of all digital certificate issued, including identifying and
conducting initial due diligence on the owners, tracking digital certificates,
providing customer support for digital certificate owners, confirming in real-
time the continued validity of each digital certificate and revoking or
renewing the digital certificates. To be effective for large public and
private communities needing digital certificates, a CA must also have a highly
scaleable and flexible infrastructure, be able to provide a full range of
digital certificate services in high volume on a 24 hour x 7 day basis and
have its public root key embedded in and supported by a wide variety of
applications utilized across IP networks.

  INTERNET IDS
   
  The Company issues Internet IDs directly to individuals and organizations
engaged in communications and commerce over the Internet. These Internet IDs
allow individuals, organizations and software developers to protect the
privacy and integrity of their communications by establishing the identity,
authority or privilege of the parties involved to avoid impersonations or
identity "spoofing" and malicious security breaches. Since its inception, the
Company has issued over 1.5 million of its Digital IDs for individuals and
over 35,000 of its Digital IDs for Web sites. The purchase of a Digital ID
allows the customer to use the Digital ID for a limited period of time,
generally 12 months. After this period, the Digital ID must be renewed for
continued usage by the customer. The Company has also established a warranty
protection program, the NetSure Protection Plan, that provides warranty
coverage to its customers at varying levels up to $250,000 in the event of
economic loss due to the theft, impersonation, corruption or loss of an
Internet ID. VeriSign has insured itself against losses under such coverage
with United States Fidelity and Guaranty Company.     
 
  Client Digital Certificates. VeriSign's Universal Digital IDs are issued
directly to individuals to enable users to exchange digitally signed and
encrypted e-mail using the S/MIME protocol. Universal Digital IDs can also be
used to replace passwords for more convenient access to and enhanced security
of Web sites.
 
  The Company currently offers two versions of Universal Digital IDs and plans
to offer a third version in the second half of 1998. These versions are
differentiated principally by the subscriber identity authentication
procedures and due diligence performed by the Company prior to issuance and
the amount of NetSure warranty protection provided:
 
    Universal Digital ID-Class 1. Class 1 Universal Digital IDs are the class
  of Universal Digital ID most commonly issued by the Company. The Company
  issues a Class 1 Universal Digital ID after authenticating a user's e-mail
  address by providing an activation code, via e-mail, that can be used to
  download the digital certificate from VeriSign's Web site. Class 1
  Universal Digital IDs have NetSure warranty protection of $1,000. The
  Company offers a Class 1 Universal Digital ID for free on a 60-day trial
  basis, but the trial version does not include replacement, revocation,
  NetSure warranty protection or other related digital certificate services.
  To date, substantially all of the Class 1 Universal Digital IDs have been
  issued without charge on a trial or promotional basis.
 
    Universal Digital ID-Class 2. The Company issues a Class 2 Universal
  Digital ID after authenticating a user's personal identity by matching
  personal information provided by the user with information contained in
  established third-party consumer credit databases. To date, the Company has
  issued Class 2 Universal Digital IDs primarily to North American residents.
  Class 2 Universal Digital IDs have NetSure warranty protection of up to
  $25,000.
 
    Universal Digital ID-Class 3. VeriSign expects to introduce a Class 3
  Universal Digital ID in the second half of 1998. A Class 3 Universal
  Digital ID will be issued after authentication of a user's identity through
  personal presence verification by VeriSign or one of its certified agents
  or affiliates. The Company anticipates that Class 3 Universal Digital IDs
  will have NetSure warranty protection of up to $50,000.
 
  Server Digital Certificates. The VeriSign Server Digital ID product line
enables organizations to implement and operate secure Web sites using the SSL
or S/MIME protocols in order to establish authenticated and private
communications and commerce on IP networks. Prior to issuing a Server Digital
ID, VeriSign establishes the authenticity of a Web site through a series of
background checks that corroborate an organization's authority to do business
under a given business name, as well as its right to operate a server with a
specific domain name or URL. These procedures protect an organization against
another server "spoofing" its site and also allows site visitors to establish
the site's authenticity. VeriSign's Server Digital IDs enable an individual's
Web browser to verify a Web site's identity automatically by checking the
site's Server Digital ID. Once this authentication has occurred, an encrypted
session based on SSL or the S/MIME messaging protocol can commence. These
private communications sessions are virtually impenetrable by external
parties, thereby protecting sensitive information from unauthorized access.
 
 
                                      36
<PAGE>
 
  The Company currently offers four versions of its Server Digital IDs,
differentiated by the target application of the server that hosts the Server
Digital ID. The Company provides NetSure warranty protection of up to $100,000
on each Secure Server ID, Global Server ID and Financial Server ID and up to
$250,000 on each EDI Server ID.
 
    Secure Server ID. VeriSign Secure Server IDs enable Web sites to
  implement SSL security features for transactions and communications
  conducted between their Web servers and individual end users. A Secure
  Server ID can also be used in conjunction with a Universal Digital ID to
  restrict access to account information and content on a server hosted on an
  IP network. The Company's public root key is embedded in more than 40
  server software applications.
 
    Global Server ID. VeriSign Global Server IDs enable organizations to
  establish worldwide 128-bit encrypted SSL sessions using Netscape
  Communicator or appropriately configured Microsoft Internet Explorer
  software. Global Server IDs are available for use by U.S. corporations and
  U.S. and foreign banks approved by the United States Department of Commerce
  Bureau of Export Administration. VeriSign Global Server IDs are currently
  the only commercially available server digital certificates for Netscape
  and Microsoft products that utilize 128-bit encryption and can be used by
  approved organizations on a global basis.
 
    Financial Server ID. VeriSign Financial Server IDs are intended for use
  with financial applications using the Open Financial Exchange specification
  developed by Microsoft, Intuit Inc. ("Intuit") and CheckFree Corporation.
  Financial Server IDs are used by financial institutions for authentication
  of their Web servers and to enable the secure exchange of data between
  these organizations and customers engaged in home banking, brokerage and
  insurance services on the Internet. The Company's financial server public
  root key is embedded in Intuit's Quicken product and will be embedded in
  the next version of Microsoft Money.
 
    EDI Server ID. VeriSign EDI Server IDs are intended for organizations or

  the indicated source and establishing that the software or content has not
  been tampered with or modified while en route over IP networks.
 
  ENTERPRISE AND ELECTRONIC COMMERCE
   
  The Company offers a broad range of turn-key and custom solutions tailored
to meet the specific needs of companies, government agencies and other
organizations that wish to issue digital certificates to customers, employees,
trading partners or citizens. The Company's enterprise and electronic commerce
solutions can be used for a variety of applications, including: controlling
access to sensitive data and account information; facilitating and protecting
online payment card transactions; enabling digitally signed e-mail; or
creating an electronic trading community. These solutions give customers the
option of issuing private label digital certificates, which have limited use
within their intranets and extranets, or VeriSign Digital IDs, which are
interoperable with IP network applications enabled with the Company's public
root key and can be customized to include customer-specified data.     
 
  Enterprise and electronic commerce solutions vary based on the nature and
complexity of the application, the degree of control customers desire to
maintain, and the degree of operational responsibility customers wish to
delegate. The modularity of the Company's WorldTrust architecture allows
certain functions of the certification process, such as registration,
authentication, issuance, revocation, renewal or replacement, to be deployed
at customer sites while maintaining a link to VeriSign's Digital ID Centers
for back-end processing. As a result, customers enjoy significant time-to-
market and cost reduction benefits by leveraging the Company's trusted,
scaleable infrastructure with complete certificate lifecycle management, high-
speed servers, redundant telecommunications, data storage and daily back-up,
full disaster recovery, availability of 24 hour x 7 day customer service and
rigorous network and physical security.

TECHNOLOGY AND ARCHITECTURE
 
  The Company employs a modular set of software applications and toolkits,
which collectively make up its proprietary WorldTrust architecture, as the
core platform for all of its digital certificate solutions. The modular design
of the WorldTrust architecture enables the Company's digital certificate
services to be distributed over one or many co-located or dispersed computer
systems, allowing certain functions of the certification process, such as
registration, authentication, issuance, revocation, renewal or replacement, to
be deployed at customer or affiliate locations while maintaining a secure and
reliable link to one of the Company's Digital ID Centers for back-end
processing. These modules can also be replicated in order to handle increased
volumes of digital certificates. Digital certificate service modules
incorporated in the WorldTrust architecture include:
   
  Subscriber Services Module. The subscriber services module supports requests
for digital certificate issuance, revocation, renewal and replacement.
Software toolkits are provided to permit rapid customization and integration

affiliate relationships. The Company markets its products and services in
Japan through VeriSign Japan, which maintains a secure Digital ID Center in
Kawasaki, Japan, and employed 20 persons as of September 30, 1997. Revenues of
VeriSign Japan and from other international customers accounted for less than
10% of revenues through 1996 and for approximately 15% of revenues for the
nine months ended September 30, 1997. See "--VeriSign Japan."     
 
RESEARCH AND DEVELOPMENT
 
  The Company believes that its future success will depend in large part on
its ability to continue to maintain and enhance its current technologies,
products and services. To this end, the Company leverages the modular nature
of its WorldTrust software architecture to enable it to rapidly develop
enhancements to its WorldTrust software and to deliver complementary new
products and services. In the past, the Company has developed products and
services both independently and through efforts with leading application
developers and major customers. The Company has also, in certain
circumstances, acquired or licensed technology from third parties, including
public key cryptography technology from RSA. Although the Company will
continue to work closely with developers and major customers in its product
development efforts, it expects that most of its future enhancements to
existing products and new products will be developed internally.
 
  The Company has several significant projects currently in development. These
include the continued enhancement of the WorldTrust architecture and
associated software toolkits to broaden functionality and provide
 
                                      45
<PAGE>
 
additional packaging and integration options and the development of new
services such as real-time status checking, secure timestamping and smart card
personalization.
 
  As of September 30, 1997, VeriSign had 42 employees dedicated to research
and development. The Company also employs independent contractors for
documentation, usability, artistic design and editorial review. Research and
development expenses were $642,000, $2.1 million and $3.6 million for the
period from April 12, 1995 (inception) to December 31, 1995, 1996 and the nine
months ended September 30, 1997, respectively. To date, all development costs
have been expensed as incurred. The Company believes that timely development
of new and enhanced products and technology are necessary to remain
competitive in the marketplace. Accordingly, the Company intends to continue
recruiting and hiring experienced research and development personnel and to
make other investments in research and development.
 
  The market for digital certificate products and related services is an
emerging market characterized by rapid technological developments, frequent
new product introductions and evolving industry standards. The emerging nature
of this market and its rapid evolution will require that the Company
continually improve the performance, features and reliability of its products
and services, particularly in response to competitive offerings and that it
introduce new products and services or enhancements to existing products and
services as quickly as possible and prior to its competitors. The success of
new product introductions is dependent on several factors, including proper
new product definition, timely completion and introduction of new products,
differentiation of new products from those of the Company's competitors and
market acceptance of the Company's new products and services. There can be no
assurance that the Company will be successful in developing and marketing new
products and services that respond to competitive and technological
developments and changing customer needs. The failure of the Company to
develop and introduce new products and services successfully on a timely basis
and to achieve market acceptance for such products and services could have a
material adverse effect on the Company's business, operating results and
financial condition. In addition, the widespread adoption of new Internet,
networking or telecommunication technologies or standards or other
technological changes could require substantial expenditures by the Company to
modify or adapt its products and services. To the extent that a specific
method other than digital certificates is adopted to enable trusted and secure
commerce and communications over IP networks, sales of the Company's existing
and planned products and services will be adversely affected and the Company's
products and services could be rendered unmarketable or obsolete, which would
have a material adverse effect on the Company's business, operating results
and financial condition. The Company believes there is a time-limited
opportunity to achieve market share, and there can be no assurance that the
Company will be successful in achieving widespread acceptance of its products
and services or in achieving market share before competitors offer products
and services with features similar to the Company's current offerings. Any
such failure by the Company could have a material adverse effect on the
Company's business, operating results and financial condition. See "Risk
Factors--Rapid Technological Change; New Product and Services Introductions."
 
CUSTOMER SUPPORT
 
  The Company believes that a high level of customer support for commerce and
enterprise customers as well as end users of digital certificates is necessary
to achieve acceptance of its digital certificates and related products and
services. The Company provides a wide range of customer support services
through a staff of customer service personnel, call center, e-mail help desk
and a Web-based self-help system. Since it introduced its first products over
two years ago, the Company has developed a substantial knowledge base of
customer support information based on its customer interactions and believes
that this offers the Company a competitive advantage. The Company's call
center is staffed from 8 a.m. to 5 p.m. PST and employs an Automated Call
Director system to provide self-help services and, if necessary, to route
support calls to available support personnel. The Company also offers Web-
based support services that are available on a 24 hour x 7 day basis and that
are frequently updated to improve existing information and to support new
services. The Company's e-mail customer support service utilizes customized
auto response systems to provide self-help recommendations and also utilizes a
staff of trained customer support agents who typically respond to customer
inquiries within 24 hours. As of September 30, 1997, the Company had 53
employees in its customer support organization.
 
                                      46
<PAGE>
 
  The Company also employs technical support personnel who work directly with
its direct sales force, distributors and customers of its electronic commerce
and enterprise solutions. The Company's annual maintenance agreements for its
electronic commerce and enterprise solutions include technical support and
upgrades. The Company also provides training programs for customers of its
enterprise and electronic commerce solutions.
 
COMPETITION
 
  The Company's digital certificate solutions are targeted at the new and
rapidly evolving market for trusted and secure communications and commerce
over IP networks. Although the competitive environment in this market has yet
to develop fully, the Company anticipates that it will be intensely
competitive, subject to rapid change and significantly affected by new product
and service introductions and other market activities of industry
participants.
 
  The Company's primary competitors are Entrust, GTE CyberTrust and IBM. The
Company also experiences competition from a number of smaller companies that
provide digital certificate solutions. The Company expects that competition
from established and emerging companies in the financial and
telecommunications industries will increase in the near term, and that the
Company's primary long-term competitors may not yet have entered the market.
Netscape has introduced software products that enable the issuance and
management of digital certificates, and the Company believes that other
companies could introduce such products. There can be no assurance that
additional companies will not offer digital certificate solutions that are
competitive with those of the Company. Increased competition could result in
pricing pressures, reduced margins or the failure of the Company's products
and services to achieve or maintain market acceptance, any of which could have
a material adverse effect on the Company's business, operating results and
financial condition.
 
  Several of the Company's current and potential competitors have longer
operating histories and significantly greater financial, technical, marketing
and other resources than the Company and therefore may be able to respond more
quickly than the Company to new or changing opportunities, technologies,
standards and customer requirements. Many of these competitors also have
broader and more established distribution channels that may be used to deliver
competing products or services directly to customers through bundling or other
means. If such competitors were to bundle competing products or services for
their customers, the demand for the Company's products and services might be
substantially reduced and the ability of the Company to distribute its
products successfully and the utilization of its services would be
substantially diminished. In addition, browser companies that embed the
Company's root keys or otherwise feature the Company as a provider of digital
certificate solutions in their Web browsers or on their Web sites could also
promote competitors of the Company or charge the Company substantial fees for
such promotions in the future. New technologies and the expansion of existing
technologies may increase the competitive pressures on the Company. There can
be no assurance that competing technologies developed by others or the
emergence of new industry standards will not adversely affect the Company's
competitive position or render its products or technologies noncompetitive or
obsolete. In addition, the market for digital certificates is nascent and is
characterized by announcements of collaborative relationships involving
competitors of the Company. The existence or announcement of such
relationships could adversely affect the Company's ability to attract and
retain customers. As a result of the foregoing and other factors, there can be
no assurance that the Company will compete effectively with current or future
competitors or that competitive pressures faced by the Company will not have a
material adverse effect on the Company's business, operating results and
financial condition. See "Risk Factors--Competition."
 
INTELLECTUAL PROPERTY
 
  The Company relies primarily on a combination of copyrights, trademarks,
trade secret laws, restrictions on disclosure and other methods to protect its
intellectual property and trade secrets. The Company also enters into
confidentiality agreements with its employees and consultants, and generally
controls access to and distribution of its documentation and other proprietary
information. Despite these precautions, it may be possible for a third party
to copy or otherwise obtain and use the Company's intellectual property or
trade secrets without
 
                                      47
<PAGE>
 
authorization. In addition, there can be no assurance that others will not
independently develop substantially equivalent intellectual property. There
can be no assurance that the precautions taken by the Company will prevent
misappropriation or infringement of its technology. A failure by the Company
to protect its intellectual property in a meaningful manner could have a
material adverse effect on the Company's business, operating results and
financial condition. In addition, litigation may be necessary in the future to
enforce the Company's intellectual property rights, to protect the Company's
trade secrets or to determine the validity and scope of the proprietary rights
of others. Such litigation could result in substantial costs and diversion of
management and technical resources, either of which could have a material
adverse effect on the Company's business, operating results and financial
condition.
   
  The Company also relies on certain licensed third-party technology, such as
public key cryptography technology licensed from RSA and other technology that
is used in the Company's products to perform key functions. In particular, the
Company has been granted a perpetual, royalty free, nonexclusive, worldwide
license to distribute products it develops that contain or incorporate the RSA
BSAFE and TIPEM products and that relate to digital certificate issuing
software, software for the management of private keys and for digitally
signing computer files on behalf of others, software for customers to preview
and forward digital certificate requests to the Company, or such other
products that, in RSA's reasonable discretion, are reasonably necessary for
the implementation of a digital certificate business. RSA is also required to
provide maintenance and technical support for these products to the Company.
RSA's BSAFE product is a software tool kit that allows for the integration of
encryption and authentication features into software applications and TIPEM is
a secure e-mail development tool kit that allows for secure e-mail messages to
be sent using one vendor's e-mail product and read by another vendor's e-mail
product. There can be no assurance that these third-party technology licenses
will continue to be available to the Company on commercially reasonable terms
or at all, and the loss of any of these technologies could have a material
adverse effect on the Company's business, operating results and financial
condition. Moreover, in the Company's current license agreements, the licensor
has agreed to defend, indemnify and hold the Company harmless with respect to
any claim by a third party that the licensed software infringes any patent or
other proprietary right. Although these licenses are fully paid, there can be
no assurance that the outcome of any litigation between the licensor and a
third party or between the Company and a third party will not lead to royalty
obligations of the Company for which the Company is not indemnified or for
which such indemnification is insufficient, or that the Company will be able
to obtain any additional license on commercially reasonable terms or at all.
In the future, the Company may seek to license additional technology to
incorporate in its products and services. There can be no assurance that any
third party technology licenses that the Company may be required to obtain in
the future will be available to the Company on commercially reasonable terms
or at all. The loss of or inability to obtain or maintain any of these
technology licenses could result in delays in introduction of the Company's
products or services until equivalent technology, if available, is identified,
licensed and integrated, which could have a material adverse effect on the
Company's business, operating results and financial condition.     
 
  From time to time, the Company has received, and may receive in the future,
notice of claims of infringement of other parties' proprietary rights. There
can be no assurance that infringement or other claims will not be asserted or
prosecuted against the Company in the future or that any past or future
assertions or prosecutions will not materially adversely affect the Company's
business, operating results and financial condition. Any such claims, with or
without merit, could be time-consuming, result in costly litigation and
diversion of technical and management personnel, cause product shipment delays
or require the Company to develop non-infringing technology or enter into
royalty or licensing agreements. Such royalty or licensing agreements, if
required, may not be available on terms acceptable to the Company, or at all.
In the event of a successful claim of product infringement against the Company
and the failure or inability of the Company to develop non-infringing
technology or license the infringed or similar technology on a timely basis,
the Company's business, operating results and financial condition could be
materially adversely affected. See "Risk Factors--Intellectual Property;
Potential Litigation."

EMPLOYEES
   
  As of September 30, 1997, the Company had 162 full-time employees. Of the
total, 38 were employed in sales and marketing, 42 in research and
development, 53 in operations, seven in practices and external affairs, three
in federal markets, and 19 in finance and administration. The Company has
never had a work stoppage, and no employees are represented under collective
bargaining agreements. The Company considers its relations with its employees
to be good. The Company's ability to achieve its financial and operational
objectives depends in large part upon its continuing ability to attract,
integrate, retain and motivate highly qualified sales, technical and
managerial personnel, and upon the continued service of its senior management
and key sales and technical personnel, none of whom is bound by an employment
agreement. Competition for such qualified personnel in the Company's industry
and geographical location in the San Francisco Bay Area is intense,
particularly in software development and product management personnel. See
"Risk Factors--Dependence on Key Personnel."     
 
FACILITIES
 
  The Company's principal administrative, sales, marketing, research and
development and operations facilities are located in two adjacent buildings in
Mountain View, California, where they occupy approximately 44,000 square feet
under leases expiring in 2001. The Company intends to obtain additional office
space in 1998 contiguous to its headquarters. The Company believes that this
additional space will be available and that its current facilities, together
with this additional space, will be adequate to meet its needs for the
foreseeable future.
 
  The Company also leases space for sales and support offices in Rosemont,
Illinois; Atlanta, Georgia; Linthicum, Maryland; Cambridge, Massachusetts; and
Melville, New York. In addition, VeriSign Japan leases space in Kawasaki,
Japan for its offices and Digital ID Center. The Company's success is largely
dependent on the uninterrupted operation of its Digital ID Centers and
computer and communications systems. See "Risk Factors--System Interruption
and Security Breaches."

stockholders or until their successors are duly elected and qualified. The
existing directors were elected pursuant to the provisions of the
Stockholders' Agreement described in "Certain Transactions," which agreement
terminates upon the closing of this offering. Executive officers are elected
by, and serve at the discretion of, the Board. The Company's Amended and
Restated Bylaws, which will become effective upon the completion of this
offering, provide that the Board will be divided into three classes, Class I,
Class II and Class III, with each class serving staggered three-year terms.
The Class I directors will stand for reelection or election at the 1998 annual
meeting of stockholders. The Class II directors will stand for reelection or

stockholders.
 
BOARD COMMITTEES
   
  The Board has established an Audit Committee to meet with and consider
suggestions from members of management, as well as the Company's independent
accountants, concerning the financial operations of the Company. The Audit
Committee also has the responsibility to review audited financial statements
of the Company and consider and recommend the employment of, and approve the
fee arrangements with, independent accountants for both audit functions and
for advisory and other consulting services. The Audit Committee is currently
comprised of Messrs. Chenevich, Compton and Tomlinson. The Board has also
established a Compensation Committee to review and approve the compensation
and benefits for the Company's key executive officers, administer the
Company's stock purchase, equity incentive and stock option plans and make
recommendations to the Board regarding such matters. The Compensation
Committee is currently comprised of Messrs. Bidzos, Chenevich and Cowan.     
 
DIRECTOR COMPENSATION
   
  Directors do not receive any cash fees for their service on the Board or any
Board committee, but they are entitled to reimbursement of all reasonable out-
of-pocket expenses incurred in connection with their attendance at Board and
Board committee meetings. At the Company's founding in April 1995, the Company
granted an option to purchase 25,000 shares of its Common Stock under the
Company's 1995 Stock Option Plan to D. James Bidzos with an exercise price of
$.12 per share. All Board members are eligible to receive stock options under
the Company's stock option plans, and outside directors receive stock options
pursuant to automatic grants of stock options under the 1995 Stock Option
Plan. In July 1996, the Company granted to each of Messrs. Bidzos, Chenevich,
Compton, Cowan and Tomlinson an option to purchase 10,000 shares of its Common
Stock under the Company's 1995 Stock Option Plan with an exercise price of
$8.00 per share. In June 1997, the Company granted to each of Messrs. Bidzos,
Compton, Cowan and Tomlinson an option to purchase 3,500 shares of its Common
Stock under the Company's 1995 Stock Option Plan with an exercise price of
$8.00 per share.     
 
                                      52
<PAGE>
 
   
  In October 1997, the Board adopted, subject to stockholder approval, the
1998 Directors Stock Option Plan (the "Directors Plan") and reserved a total
of 125,000 shares of the Company's Common Stock for issuance thereunder.
Members of the Board who are not employees of the Company, or any parent,
subsidiary or affiliate of the Company, are eligible to participate in the
Directors Plan. The option grants under the Directors Plan are automatic and
nondiscretionary, and the exercise price of the options is 100% of the fair
market value of the Common Stock on the date of grant. Each eligible director
who first becomes a member of the Board on or after the effective date of the
Registration Statement of which this Prospectus forms a part (the "Effective
Date") will initially be granted an option to purchase 15,000 shares (an
"Initial Grant") on the date such director first becomes a director. On each
anniversary of a director's Initial Grant (or most recent grant if such
director was ineligible to receive an Initial Grant), each eligible director
will automatically be granted an additional option to purchase 7,500 shares if
such director has served continuously as a member of the Board since the date
of such director's Initial Grant (or most recent grant if such director did
not receive an Initial Grant). The term of such options is ten years, provided
that they will terminate seven months following the date the director ceases
to be a director or, if the Company so specifies in the grant, a consultant of
the Company (twelve months if the termination is due to death or disability).
All options granted under the Directors Plan will vest as to 6.25% of the
shares each quarter after the date of grant, provided the optionee continues
as a director or, if the Company so specifies in the grant, as a consultant of
the Company. Additionally, immediately prior to the dissolution or liquidation
of the Company or a "change in control" transaction, all options granted
pursuant to the Directors Plan will accelerate and will be exercisable for a
period of up to six months following the transaction, after which period any
unexercised options will expire.     
 
COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
  Mr. Bidzos, a member of the Compensation Committee, is an Executive Vice
President and a director of Security Dynamics, which beneficially owns
approximately 27.0% of the Company's Common Stock, and also served as the
Company's Chief Executive Officer from April to July 1995. See "Certain
Transactions." No interlocking relationship exists between the Board or
Compensation Committee and the board of directors or compensation committee of
any other company, nor has any such interlocking relationship existed in the
past.

(1) Options granted in 1997 were granted under the Company's 1995 Stock Option
    Plan or, in the case of Mr. Sclavos, the Company's 1997 Stock Option Plan.
    These options become exercisable with respect to 25% of the shares covered
    by the option on the first anniversary of the date of grant and with
    respect to an additional 6.25% of these shares each quarter thereafter.
    These options have a term of seven years. Upon certain changes in control
    of the Company, this vesting schedule will accelerate as to 50% of any
    shares that are then unvested. See "--Employee Benefit Plans" and "--
    Compensation Arrangements" for a description of the material terms of
    these options.
(2) Potential realizable values are net of exercise price but before taxes,
    and are based on the assumption that the Common Stock of the Company
    appreciates at the annual rate shown (compounded annually) from the date
    of grant until the expiration of the seven-year term. These numbers are
    calculated based on Securities and Exchange Commission requirements and do
    not reflect the Company's projection or estimate of future stock price
    growth.
(3) The Company granted options to purchase 1,307,100 shares of Common Stock
    to employees from January 1 through November 15, 1997.
(4) Options were granted at an exercise price equal to the fair market value
    of the Company's Common Stock, as determined by the Board of Directors.

  The following table sets forth for each of the Named Executive Officers the

  No options were exercised during 1997 by the Named Executive Officers. No
compensation intended to serve as incentive for performance to occur over a
period longer than one year was paid pursuant to a long-term incentive plan
during 1997 to any Named Executive Officer. The Company does not have any
defined benefit or actuarial plan under which benefits are determined
primarily by final compensation and years of service with any of the Named
Executive Officers.
 
EMPLOYEE BENEFIT PLANS
 
  1995 Stock Option Plan. In April 1995, the Board adopted and the
stockholders approved the 1995 Stock Option Plan. At that time, 2,145,000
shares of Common Stock were reserved for issuance under the 1995 Stock Option
Plan, which number was increased to 4,145,000 shares in May 1996. As of
September 30, 1997, options to purchase 1,803,744 shares had been exercised
(net of repurchases), options to purchase an additional 2,000,974 shares of
Common Stock were outstanding under the 1995 Stock Option Plan with a weighted
average exercise price of $1.49 and 340,282 shares remained available for
future grants. Following the closing of this offering, no additional options
will be granted under the 1995 Stock Option Plan. Options granted under the
1995 Stock Option Plan are subject to terms substantially similar to those
described below with respect to options to be granted under the Equity
Incentive Plan. The 1995 Stock Option Plan does not provide for issuance of
restricted stock or stock bonus awards.
 
  1997 Stock Option Plan. In October 1997, the Board adopted and the Company's
stockholders approved the 1997 Stock Option Plan. At that time, 800,000 shares
of Common Stock were reserved for issuance under the 1997 Stock Option Plan.
Following the closing of this offering, no options will be granted under the
1997 Stock Option Plan. Options granted under the 1997 Stock Option Plan are
subject to terms substantially similar to those described below with respect
to options granted under the Equity Incentive Plan. The 1997 Stock Option Plan
does not provide for issuance of restricted stock or stock bonus awards.
 
  1998 Equity Incentive Plan. In October 1997, the Board adopted, subject to
stockholder approval, the Equity Incentive Plan. The total number of shares of
Common Stock reserved for issuance thereunder is 2,000,000. The Equity
Incentive Plan will become effective on the Effective Date and will serve as
the successor to the 1995 Stock Option Plan and the 1997 Stock Option Plan
(the "Prior Plans"). Options granted under the Prior Plans before their
termination will remain outstanding according to their terms, but no further
options will be granted under the Prior Plans after the Effective Date. Shares
that: (a) are subject to issuance upon exercise of an option granted under the
Prior Plans, or the Equity Incentive Plan that cease to be subject to such
option for any reason other than exercise of such option; (b) have been issued
pursuant to the exercise of an option granted under the Prior Plans or the
Equity Incentive Plan with respect to which the Company's right of repurchase
has not lapsed and are subsequently repurchased by the Company; (c) are
subject to an award granted pursuant to restricted stock purchase agreements
under the Equity Incentive Plan that are forfeited or are repurchased by the
Company at the original issue price; or (d) are subject to stock bonuses
granted under the Equity Incentive Plan that otherwise terminate without
shares being issued, will again be available for grant and issuance under the
Equity Incentive Plan. Any authorized shares not issued or subject to
outstanding grants under the Prior Plans on the Effective Date will no longer
be available for grant and issuance under the Prior Plans but will be
available for grant and issuance under the Equity Incentive Plan. The Equity
Incentive Plan will terminate in October 2007, unless sooner terminated in
accordance with the terms of the Equity Incentive Plan. The Equity Incentive
Plan authorizes the award of options, restricted stock awards and stock
bonuses (each an "Award"). No person will be eligible to receive more than
400,000 shares in any calendar year pursuant to Awards under the Equity
Incentive Plan other than a new employee of the Company who will be eligible
to receive no more than 1,000,000 shares in the calendar year in which such
employee commences employment. The Equity Incentive Plan will be administered
by the Compensation Committee. The Compensation Committee has the authority to
construe and interpret the Equity Incentive Plan and any agreement made
thereunder, grant Awards and make all other determinations necessary or
advisable for the administration of the Equity Incentive Plan.
 
  The Equity Incentive Plan provides for the grant of both incentive stock
options ("ISOs") that qualify under Section 422 of the Internal Revenue Code
of 1986, as amended (the "Code"), and nonqualified stock options
 
                                      56
<PAGE>
 
("NQSOs"). ISOs may be granted only to employees of the Company or of a parent
or subsidiary of the Company. NQSOs (and all other Awards other than ISOs) may
be granted to employees, officers, directors, consultants, independent
contractors and advisors of the Company or any parent or subsidiary of the
Company, provided such consultants, independent contractors and advisors
render bona fide services not in connection with the offer and sale of
securities in a capital-raising transaction ("Eligible Service Providers").
The exercise price of ISOs must be at least equal to the fair market value of
the Company's Common Stock on the date of grant. The exercise price of NQSOs
must be at least equal to 85% of the fair market value of the Company's Common
Stock on the date of grant. The maximum term of options granted under the
Equity Incentive Plan is ten years. Awards granted under the Equity Incentive
Plan may not be transferred in any manner other than by will or by the laws of
descent and distribution and may be exercised during the lifetime of the
optionee only by the optionee (unless otherwise determined by the Compensation
Committee and set forth in the Award agreement with respect to Awards that are
not ISOs). Options granted under the Equity Incentive Plan generally expire
three months after the termination of the optionee's service to the Company or
a parent or subsidiary of the Company, except in the case of death or
disability, in which case the options generally may be exercised up to 12
months following the date of death or termination of service. Options will
generally terminate immediately upon termination for cause. In the event of
the Company's dissolution or liquidation or a "change in control" transaction,
outstanding Awards may be assumed or substituted by the successor corporation
(if any). If a successor corporation (if any) does not assume or substitute
the Awards, they will expire upon the effectiveness of the transaction. The
Committee, in its discretion, may provide that the vesting of any or all
Awards will accelerate prior to the effectiveness of the transaction.
   
  1998 Employee Stock Purchase Plan. In December 1997, the Board adopted,
subject to stockholder approval, the Purchase Plan and reserved 500,000 shares
of the Company's Common Stock for issuance thereunder. The Purchase Plan will
be administered by the Compensation Committee of the Board. The Compensation
Committee will have the authority to construe and interpret the Purchase Plan
and its decisions in such capacity will be final and binding. The Purchase
Plan will become effective on the first business day on which price quotations
for the Company's Common Stock are available on the Nasdaq National Market.
Employees generally will be eligible to participate in the Purchase Plan if
they are customarily employed by the Company (or its parent or any
subsidiaries that the Company designates) for more than 20 hours per week and
more than five months in a calendar year and are not (and would not become as
a result of being granted an option under the Purchase Plan) 5% stockholders
of the Company (or its designated parent or subsidiaries). Eligible employees
may select a rate of payroll deduction between 2% and 10% of their
compensation and are subject to certain maximum purchase limitations that will
be described in the Purchase Plan. A participant may change the rate of
payroll deductions or withdraw from an Offering Period by notifying the
Company in writing. Participation in the Purchase Plan will end automatically
upon termination of employment for any reason. Except for the first offering,
each offering under the Purchase Plan will be for a period of 24 months (the
"Offering Period") and will consist of six-month purchase periods (each a
"Purchase Period"). The first Offering Period is expected to begin on the
first business day on which price quotations for the Company's Common Stock
are available on the Nasdaq National Market and, depending on the effective
date of this Registration Statement, may be greater or less than 24 months
long. Offering Periods thereafter will begin on February 1 and August 1. The
Compensation Committee may change the duration of Offering Periods (up to a
maximum of 24 months) and the number and duration of Purchase Periods (up to a
maximum of four per Purchase Period). The Compensation Committee will also be
able to terminate any Offering Period as of the end of any Purchase Period
within the affected Offering Period. Each participant will be granted an
option on the first day of the Offering Period and such option will be
automatically exercised on the last day of each Purchase Period during the
Offering Period. The purchase price for the Company's Common Stock purchased
under the Purchase Plan is 85% of the lesser of the fair market value of the
Company's Common Stock on the first day of the applicable Offering Period and
the last day of the applicable Purchase Period. The Board will have the power
to change the duration of Offering Periods and Purchase Periods without
stockholder approval, if such change is announced at least 15 days prior to
the beginning of the Offering or Purchase Period to be affected. The Purchase
Plan will be intended to qualify as an "employee stock purchase plan" under
Section 423 of the Code. Rights granted under the Purchase Plan will not be
transferable by a participant other than by will or the laws of descent and
    
                                      57
<PAGE>
 
distribution. The Purchase Plan will provide that, in the event of the
proposed dissolution or liquidation of the Company, the Offering Period will
terminate immediately prior to the consummation of such proposed action,
provided that the Compensation Committee may fix a different date for
termination of the Purchase Plan and may give each participant the opportunity
to purchase shares under the Purchase Plan prior to such termination. The
Purchase Plan will provide that, in the event of certain "change of control"
transactions, the Plan will continue for all Offering Periods that began prior
to the transaction and shares will be purchased based on the fair market value
of the surviving corporation's stock on each Purchase Date. The Purchase Plan
will terminate in December 2007, unless earlier terminated pursuant to the
terms of the Purchase Plan. The Board will have the authority to amend,
terminate or extend the term of the Purchase Plan, except that no such action
may adversely affect any outstanding options previously granted under the
Purchase Plan and stockholder approval is required to increase the number of
shares that may be issued or change the terms of eligibility under the
Purchase Plan.
 
  401(k) Plan. The Board maintains the VeriSign, Inc. 401(k) Plan (the "401(k)
Plan"), a defined contribution plan intended to qualify under Section 401 of
the Code. All eligible employees who are at least 18 years old and have been
employed by the Company for one month may participate in the 401(k) Plan. An
eligible employee of the Company may begin to participate in the 401(k) Plan
on the first day of January, April, July or October of the plan year
coinciding with or following the date on which such employee meets the
eligibility requirements. A participating employee may make pre-tax
contributions of a whole percentage (not more than 15%) of his or her eligible
compensation and up to 100% of any cash bonus, subject to limitations under
the federal tax laws. Employee contributions and the investment earnings
thereon are fully vested at all times. The 401(k) Plan permits, but does not
require, additional matching and profit-sharing contributions by the Company
on behalf of the participants. The Company has not made matching or profit-
sharing contributions. Contributions by employees or the Company to the 401(k)
Plan, and income earned on plan contributions, are generally not taxable to
employees until withdrawn, and contributions by the Company, if any, should be
deductible by the Company when made. The trustee under the 401(k) Plan, at the
direction of each participant, invests the assets of the 401(k) Plan in
selected investment options.
   
  Executive Loan Program of 1996. In November 1996, the Compensation Committee
adopted the Company's Executive Loan Program of 1996 (the "Executive Loan
Program"). Pursuant to the Executive Loan Program, the Company's Chief
Executive Officer and each Vice President of the Company (each a "Qualified
Borrower") are each entitled to borrow an aggregate of up to $250,000 from the
Company. Each loan made under the Executive Loan Program is a full recourse
loan and bears interest at the then-minimum interest rate to avoid imputation
of income under federal, state and local tax laws. Interest on any loan made
under the Executive Loan Program is due and payable on December 31 of each
year in which such loan is outstanding. Principal and accrued interest are
payable in full on any such loan upon the earlier of December 31, 2005 or 90
days after the termination of the Qualified Borrower's employment with the
Company, unless extended by a separate written agreement approved by the
Board. Each loan made under the Executive Loan Program must be secured by
collateral represented by Common Stock of the Company or other marketable
securities acceptable to the Board having a fair market value equaling or
exceeding the principal amount of the loan.     
 
COMPENSATION ARRANGEMENTS
 
  Mr. Sclavos's employment offer letter of June 1995, as amended in October
1995, provided for an initial annual salary of $175,000 and an initial annual
bonus of up to $50,000 per year. In addition, it provided for a loan to Mr.
Sclavos of $48,000 which was to be forgiven after the first anniversary of Mr.
Sclavos's employment with the Company. This loan was forgiven by the Board in
October 1996. Mr. Sclavos was also granted an option to purchase 616,000
shares of Common Stock with an exercise price of $.12 per share. In October
1996, this option was amended such that it became immediately exercisable. Mr.
Sclavos exercised this option in full in November 1996. In connection with
this exercise, the Company loaned Mr. Sclavos $73,920 pursuant to the terms of
the Executive Loan Program, representing the full exercise price of such
option. As of September 30, 1997, 269,500 of the shares Mr. Sclavos received
upon exercise of the option were subject to a right of repurchase on behalf of
the Company. This right lapses as to 38,500 shares per quarter. Mr. Sclavos's
employment is "at will" and thus can be terminated at any time, with or
without cause.

  Michael S. Baum, Dana L. Evan, Arnold Schaeffer and Richard A. Yanowitch
were granted options to purchase 150,000, 170,000, 200,000 and 290,000 shares,
respectively, of Common Stock under the 1995 Stock Option Plan, at exercise
prices ranging from $.12 to $6.00. Each of these options is subject to the
standard four-year vesting schedule under the 1995 Stock Option Plan or, in
certain circumstances, is immediately exercisable, subject to the Company's
right to repurchase shares subject to such options, which repurchase right
lapses on a schedule similar to the vesting schedule for options granted under
the 1995 Stock Option Plan. However, upon the occurrence of certain change-in-
control transactions, 50% of each such Named Executive Officer's then-unvested
options will become vested or, if applicable, the right of repurchase will
lapse as to 50% of the shares covered by such right of repurchase.     
 
INDEMNIFICATION OF DIRECTORS AND EXECUTIVE OFFICERS AND LIMITATION OF
LIABILITY
 
  As permitted by the Delaware General Corporation Law (the "DGCL"), the
Company's Third Amended and Restated Certificate of Incorporation, which will
become effective upon the closing of this offering, includes a provision that
eliminates the personal liability of its directors for monetary damages for
breach of fiduciary duty as a director, except for liability (i) for any
breach of the director's duty of loyalty to the Company or its stockholders,
(ii) for acts or omissions not in good faith or that involve intentional
misconduct or a knowing violation of law, (iii) under section 174 of the DGCL
(regarding unlawful dividends and stock purchases) or (iv) for any transaction
from which the director derived an improper personal benefit.
   
  As permitted by the DGCL, the Company's Amended and Restated Bylaws, which
will become effective upon the completion of this offering, provide that (i)
the Company is required to indemnify its directors and officers to the fullest
extent permitted by the DGCL, subject to certain very limited exceptions, (ii)
the Company may indemnify its other employees and agents to the extent that it
indemnifies its officers and directors, unless otherwise required by law, its
Certificate of Incorporation, its Amended and Restated Bylaws, or agreement,
(iii) the Company is required to advance expenses, as incurred, to its
directors and executive officers in connection with a legal proceeding to the
fullest extent permitted by the DGCL, subject to certain very limited
exceptions and (iv) the rights conferred in the Amended and Restated Bylaws
are not exclusive.     
 
  The Company has entered into Indemnification Agreements with each of its
current directors and certain of its executive officers and intends to enter
into such Indemnification Agreements with each of its other executive officers
to give such directors and executive officers additional contractual
assurances regarding the scope of the indemnification set forth in the
Company's Certificate of Incorporation and Amended and Restated Bylaws and to
provide additional procedural protections. At present, there is no pending
litigation or proceeding involving a director, officer or employee of the
Company regarding which indemnification is sought, nor is the Company aware of
any threatened litigation that may result in claims for indemnification.

TRANSACTIONS WITH DIRECTORS, EXECUTIVE OFFICERS AND 5% STOCKHOLDERS
 
  The Company has financed its operations to date through a series of private
Common Stock and Preferred Stock financings. Upon the closing of this
offering, all shares of Preferred Stock will be converted into shares of
Common Stock at a conversion rate of one share of Common Stock for each share
of Preferred Stock. See "Description of Capital Stock."
   
  Common Stock at Formation. In April 1995, the Company sold an aggregate of
4,688,333 shares of its Common Stock at a purchase price of $.12 per share to
certain individuals and entities. Among the purchasers were the following 5%
stockholders, directors and entities affiliated with directors of the Company,
who purchased the number of shares set forth opposite their respective names:
RSA--4,000,000 shares; Bessemer Venture Partners DCI--258,333 shares; D. James
Bidzos--125,000 shares; Kairdos L.L.C.--100,000 shares; and TZM Investment
Fund--80,000 shares. Mr. Bidzos is the Chairman of the Board of the Company,
the President and Chief Executive Officer of RSA and the General Manager and a
member of Kairdos L.L.C. Mr. Tomlinson, a director of the Company, is a
general partner of TZM Investment Fund and TZM Investment Fund is a member of
Kairdos L.L.C. Mr. Cowan, a director of the Company, is a general partner of
the general partner of Bessemer Venture Partners DCI. All purchasers paid cash
except RSA, which assigned and transferred to the Company equipment, assets
and technology, which assets and technology included certain specified
software developed or under development by RSA relating to digital certificate
issuance and management, certain tangible personal property, consisting mostly
of computer equipment, and all of RSA's right, title and interest in certain
specified agreements to provide digital certificate services. In connection
with the contribution of these assets to the Company, RSA entered into a
BSAFE/TIPEM OEM Master License Agreement with the Company pursuant to which
the Company was granted a perpetual, royalty free, nonexclusive, worldwide
license to distribute products it develops that contain or incorporate the RSA
BSAFE and TIPEM products and that relate to digital certificate issuing
software, software for the management of private keys and for digitally
signing computer files on behalf of others, software for customers to preview
and forward digital certificate requests to the Company, or such other
products that, in RSA's reasonable discretion, are reasonably necessary for
the implementation of a digital certificate business. RSA is also required to
provide maintenance and technical support for these products to the Company.
RSA's BSAFE product is a software tool kit that allows for the integration of
encryption and authentication features into software applications and TIPEM is
a secure e-mail development tool kit that allows for secure e-mail messages to
be sent using one vendor's e-mail product and read by another vendor's e-mail
product. Also in connection with this contribution of assets, RSA entered into
a Non-Compete and Non-Solicitation Agreement pursuant to which RSA agreed, for
a five-year period, not to compete with the Company's certificate authority
business.

  Stockholders' Agreement. In April 1995, the Company and each of the persons
who were then stockholders (the "Parties") entered into a Stockholders'
Agreement, which was amended at the time of the Series B Preferred Stock
financing and again in November 1996, when the Series C Preferred Stock
financing was closed, to include as parties to the agreement the new holders
of Preferred Stock. The Stockholders' Agreement, as amended, prohibits the
Parties from transferring any of their shares of capital stock of the Company,
without the prior consent of the Board and a majority in interest of the other
Parties, to certain specified corporations and entities affiliated with such
corporations. The Stockholders' Agreement also provides that no Party can vote
shares of capital stock of the Company with voting rights in excess of 45% of
the voting rights of the total voting capital stock of the Company entitled to
vote on any matter, thereby prohibiting a Party with more than 45% of the
voting rights of the total voting capital stock of the Company from
controlling the voting on any given matter. Finally, the Stockholders'
Agreement provides that, so long as any of Kleiner Perkins Caufield & Byers
VII, Bessemer Venture Partners DCI, VISA and Intel Corporation retained at
least 50% of the shares issued to them in the Series A or Series B Preferred
Stock financing, or so long as RSA retains not less than the lesser of 10% of
the issued and outstanding voting shares of the Company or 75% of the shares
of Common Stock held by it immediately following the Series A Preferred Stock
financing, the Company and the stockholders would cause and maintain the
election to the Board of a representative of each of those five entities that
satisfied their respective requirement. The Stockholders' Agreement terminates
upon the closing of this offering.
 
  Co-Sale Agreement. In February 1996, the Company, each of the purchasers of
Series B Preferred Stock and RSA entered into a Co-Sale Agreement, pursuant to
which the holders of Series B Preferred Stock were granted rights to
participate in certain sales of capital stock of the Company owned by RSA.
Such co-sale rights will terminate upon the closing of this offering.
 
  Investors' Rights Agreement. In November 1996, the Company, all of the
current holders of Preferred Stock and the purchasers of Common Stock in April
1995 entered into an Amended and Restated Investors' Rights Agreement (the
"Investors' Rights Agreement") pursuant to which the holders of all such
Preferred or Common Stock (the "Investors") have certain registration rights
with respect to their shares of Common Stock following this offering. See
"Description of Capital Stock--Registration Rights." Pursuant to the terms of
the Investors' Rights Agreement, each of the Investors and Stratton Sclavos,
the Company's President and Chief Executive Officer and a director of the
Company, were granted a right of first offer with respect to certain future
sales of securities by the Company.
 
  Officer Loans. In November 1996, in connection with the exercise of stock
options granted under the 1995 Stock Option Plan, the Company permitted four
executive officers, Richard A. Yanowitch, Ethel E. Daly, Dana L. Evan and
Stratton D. Sclavos to purchase shares of Common Stock in exchange for
promissory notes issued under its Executive Loan Program in the amounts of
$217,500, $105,000, $93,750 and $73,920, respectively. See "Management--
Employee Benefit Plans--Executive Loan Program of 1996." In June 1997, in
connection with the exercise of a stock option granted under the 1995 Stock
Option Plan, the Company permitted Nicholas F. Piazzola, an executive officer,
to purchase shares of Common Stock in exchange for a promissory note issued
under the Executive Loan Program in the amount of $115,425. Each note is a
recourse note that is secured by the shares purchased with that note. The
notes bear interest at the rate of 6.95% per annum (6.87% in the case of Mr.
Piazzola), payable quarterly, and are due and payable on the earlier of
December 31, 2005 or the date the borrowers' employment relationship with the
Company is terminated, unless otherwise extended by a separate
 
                                      61
<PAGE>
 
written agreement approved by the Board. During the nine months ended
September 30, 1997, the Company paid a bonus in the amount of the interest
accrued under each such executive officer's promissory note in the amounts of
$17,426, $8,412, $7,511 and $5,922 for Mr. Yanowitch, Ms. Daly, Ms. Evan and
Mr. Sclavos, respectively.
   
  Development Agreement. In September 1997, the Company and Security Dynamics,
the parent company of RSA, entered into a Master Development and License
Agreement (the "Development Agreement"). Mr. Bidzos, the Chairman of the Board
of the Company, is also a director of Security Dynamics. Pursuant to the
Development Agreement, the Company will develop a customized certificate
authority product based upon the Company's WorldTrust software application in
order to enable Security Dynamics to offer a product with encryption and
digital certificate authority functionality. The Company has retained the
ownership rights to the technology developed under this agreement, except to
the extent such technology constitutes derivatives of Security Dynamics's pre-
existing technology or such technology is solely created by Security Dynamics.
The Development Agreement provides that Security Dynamics will pay the Company
an aggregate of $2.7 million as an initial license fee, $900,000 of which was
paid in October 1997 and the remainder of which will be payable upon the
achievement of certain technical milestones, which include a software code
completion milestone of February 6, 1998, the release of a beta version of
this product by February 27, 1998 and the release of the final version of the
product by April 1, 1998. Commencing in March 1998, Security Dynamics will
also be required to pay the Company a monthly product support fee for a three-
year period, and thereafter for successive annual terms, unless either of the
parties elects to terminate such product support within 60 days prior to the
end of the term or Security Dynamics terminates support services at any time
on 60 days prior written notice to the Company. For a yearly fee, Security
Dynamics can purchase product maintenance services. For so long as Security
Dynamics is paying such maintenance fees, the Company will be obligated, at no
additional cost, to provide Security Dynamics with non-exclusive first-to-
market access to new technologies developed by the Company that are relevant
to the business of providing enterprise security solutions or solutions for
secure business communications. The Company is also obligated, upon the
request of Security Dynamics, to make its other technology available to
Security Dynamics and to offer maintenance after the term of the agreement on
certain "most favored pricing" terms.     
 
  Microsoft Agreements. In November 1996, the Company sold an aggregate of
3,562,500 shares of its Series C Preferred Stock at a cash purchase price of
$8.00 per shares to 11 entities. Among the purchasers was Microsoft, a 5%
stockholder, which purchased 812,500 shares. In November 1997, the Company
entered into a Certificate Authority Preferred Provider Agreement under which
the Company will be featured as the preferred provider of digital certificates
for Microsoft customers. Upon the execution of this agreement, the Company
issued Microsoft 100,000 shares of Common Stock valued at $800,000.
   
  VISA Agreements. In April 1996, the Company entered into a Private Label
Agreement with VISA under which the Company developed and operates a digital
certificate system for VISA's member banks, based on a private VISA root key.
The Company provides certificate registration and issuing and management
functions through its Digital ID Center and retains the ownership rights to
this digital certificate system developed for VISA. The Company provides, at
no additional charge, all maintenance and support for the VISA digital
certificate system. If the Company does not meet certain minimum service
standards, or if the VISA system experiences a degradation in the quality of
service, the Company would be required to pay monetary penalties in the event
that the system is unavailable. VISA could terminate this agreement in the
event the service, once fully available in final form, is unavailable for a
significant amount of time. This agreement expires two and one-half years from
the earlier of the commencement of the pilot program or April 8, 1997. The
Company received aggregate payments from VISA of $455,000 during 1996 and
$675,000 during the nine months ended September 30, 1997, in the form of
development fees, set-up fees and certificate volume-based subscriber fees.
VISA is obligated to continue to pay subscriber fees for the remainder of the
term of this agreement. VISA prepays these fees on a quarterly basis and are
subject to offset against certificates issued. VISA is not entitled to any
refunds in the event that sufficient certificates are not issued to offset any
remaining prepaid subscriber fees. The Company is also obligated to provide
VISA with certain "most favored pricing" rights. VISA has the right     
 
                                      62
<PAGE>
 
   
to terminate this agreement after April 1, 1998 by entering into a license
agreement with the Company and paying licensing fees as well as a royalty for
future certificates issued. Otherwise, the agreement is terminable upon the
completion of its term (or earlier in the event of a material breach of the
agreement by the other party), upon bankruptcy or insolvency of the other
party or upon the Company's failure to provide support.     
 
  In October 1996, the Company entered into a Private Label Agreement with
VISA under which the Company developed a pilot digital certificate system,
based on a private VISA root key, which provides certificate registration and
issuing and management functions through VeriSign's operations and Digital ID
Center in connection with the VISA Cash stored value card and the Chip Card
Payment Service. This agreement expired in October 1997. The Company received
aggregate payments of $40,000 during 1996 and $126,000 during the nine months
ended September 30, 1997, in the form of development fees, operation fees and
subscriber fees.
 
  Sublease with Security Dynamics. Since September 1996, the Company has
sublet approximately 12,700 square feet of space for its offices in Cambridge,
Massachusetts. This space is subleased from Security Dynamics pursuant to a
sublease that expires in March 1998. The Company made lease payments to
Security Dynamics of $17,646 during 1996 and $130,624 during the nine months
ended September 30, 1997. The Company is obligated to pay monthly rent of
approximately $19,000 for the remainder of 1997 and monthly rent of
approximately $20,000 from January 1998 through the expiration date. The
Company is also obligated to pay all electricity, heating, ventilation and air
conditioning costs for the subleased premises.
 
CERTAIN BUSINESS RELATIONSHIPS
 
  Legal Fees. During 1996 and the nine months ended September 30, 1997, the
law firm of Tomlinson Zisko Morosoli & Maser LLP, of which Mr. Tomlinson is a
partner, provided legal services to the Company on a variety of matters.
During 1996 and the nine months ended September 30, 1997, the Company paid
Tomlinson Zisko Morosoli & Maser LLP an aggregate of $344,120 and $106,252,
respectively.
 
  The Company believes that the terms of each of the transactions described
above, taken as a whole, were no less favorable to the Company than the
Company could have obtained from unaffiliated third parties.

                         DESCRIPTION OF CAPITAL STOCK
 
  As of October 31, 1997, assuming the conversion of all outstanding shares of
Preferred Stock into shares of Common Stock, there were outstanding 16,668,509
shares of Common Stock, each with a par value of $.001, held of record by
approximately 109 stockholders, and outstanding options to purchase 2,362,258
shares of Common Stock.
 
  The following summary of certain provisions of the Common Stock and
Preferred Stock does not purport to be complete and is subject to, and
qualified in its entirety by, the provisions of the Company's Certificate of
Incorporation, which is included as an exhibit to the Registration Statement,
of which this Prospectus forms a part, and by the provisions of applicable
law.
 
COMMON STOCK
 
  Upon the closing of this offering, the Company will be authorized to issue
50,000,000 shares of Common Stock. Subject to preferences that may be
applicable to any Preferred Stock outstanding at the time, the holders of
outstanding shares of Common Stock are entitled to receive dividends out of
assets legally available therefor at such times and in such amounts as the
Board from time to time may determine. Holders of Common Stock are entitled to
one vote for each share held on all matters submitted to a vote of
stockholders. Cumulative voting for the election of directors will not be
authorized by the Company's Amended and Restated Certificate of Incorporation,
which means that the holders of a majority of the shares voted can elect all
of the directors then standing for election. The Common Stock is not entitled
to preemptive rights and is not subject to conversion or redemption. Upon
liquidation, dissolution or winding-up of the Company, the assets legally
available for distribution to stockholders are distributable ratably among the
holders of the Common Stock and any participating Preferred Stock outstanding
at that time after payment of liquidation preferences, if any, on any
outstanding Preferred Stock and payment of other claims of creditors. Each
outstanding share of Common Stock is, and all shares of Common Stock to be
outstanding upon completion of this offering will be upon payment therefor,
duly and validly issued, fully paid and nonassessable.
 
PREFERRED STOCK
 
  Upon the closing of this offering, each outstanding share of Preferred Stock
(the "Convertible Preferred") will be converted into shares of Common Stock.
See Note 6 of Notes to Consolidated Financial Statements for a description of
the Convertible Preferred. Following the offering, the Company will be
authorized to issue up to 5,000,000 shares of "blank check" Preferred Stock.
The Board is authorized, subject to any limitations prescribed by Delaware
law, to provide for the issuance of Preferred Stock in one or more series, to
establish from time to time the number of shares to be included in each such
series, to fix the rights, preferences and privileges of the shares of each
wholly unissued series and any qualifications, limitations or restrictions
thereon, and to increase or decrease the number of shares of any such series
(but not below the number of shares of such series then outstanding), without
any further vote or action by the stockholders. The Board may authorize the
issuance of Preferred Stock with voting or conversion rights that could
adversely affect the voting power or other rights of the holders of Common
Stock. The issuance of Preferred Stock may have the effect of delaying,
deferring or preventing a change in control of the Company and may adversely
affect the market price of the Common Stock, and the voting and other rights
of the holders of Common Stock. The Company has no current plan to issue any
shares of Preferred Stock.
 
REGISTRATION RIGHTS
 
  Following this offering, the holders of approximately 14,719,339 shares of
Common Stock (representing the purchasers of Common Stock at the founding of
the Company in April 1995 and all of the purchasers of Preferred Stock) (the
"Holders") will have certain rights to cause the Company to register those
shares (the "Registrable Securities") under the Securities Act pursuant to the
Investors' Rights Agreement. The holders of at least a majority of the
Registrable Securities may require, after 180 days from the effective date of
this
 
                                      66
<PAGE>
 
offering, that the Company use its best efforts to effect up to two
registrations. Holders not part of the initial registration demand are
entitled to notice of such registration and are entitled to include shares of
Registrable Securities therein. These registration rights are subject to
certain conditions and limitations, including (i) the right, under certain
circumstances, of the underwriters of an offering to limit the number of
shares included in such registration and (ii) the right of the Company to
delay the filing of a registration statement for not more than 120 days after
receiving the registration demand. The Company is obligated to pay all
registration expenses incurred in connection with such registration (other
than underwriters' discounts and commissions) and the reasonable fees and
expenses of a single counsel to the selling Holders.
 
  In addition, if the Company proposes to register any of its securities under
the Securities Act (other than a registration relating solely to the sale of
securities to participants in a Company stock plan, a registration on a form
that does not include substantially the same information as would be required
in a registration statement covering the sale of the Registrable Securities or
a registration in which the only Common Stock being registered is Common Stock
issuable upon conversion of debt securities that are also being registered) in
connection with the sale of such securities solely for cash, whether or not
for sale for its own account, the Holders are entitled to notice of such
registration and are entitled to include Registrable Securities therein. These
rights are subject to certain conditions and limitations, including the right
of the underwriters of an offering to limit the number of shares included in
such registration under certain circumstances. The Company is obligated to pay
all registration expenses incurred in connection with such registration other
than underwriters' discounts and commissions. If the Company were to initiate
a registration and include shares pursuant to this "piggyback" right, such
sales might have an adverse effect on the Company's ability to raise capital.
 
  The Holders may also require the Company, on no more than two occasions in
any twelve-month period, to register all or a portion of their Registrable
Securities on Form S-3 under the Securities Act when such form becomes
available for use by the Company, if the securities to be so registered
represent an aggregate selling price to the public of not less than $1.0
million. The Holders who are not part of the initial registration demand are
entitled to notice of such registration and are entitled to include shares of
Registrable Securities therein. These registration rights are subject to
certain conditions and limitations, including the right of the Company to
delay the filing of a registration statement on Form S-3 for a period of not
more than 60 days after receiving the registration demand. The Company is
obligated to pay all registration expenses incurred in connection with such
registration (other than underwriters' discounts and commissions) and the
reasonable fees and expenses of a single counsel to the selling Holders.
 
  Each stockholder's registration rights will expire upon the earlier of the
fifth anniversary of the closing of this offering or at such time as the
stockholder can sell all of its securities under Rule 144(k).
 
DELAWARE ANTI-TAKEOVER LAW AND CERTAIN CHARTER AND BYLAW PROVISIONS
 
  Upon the closing of this offering, the Company will be subject to the
provisions of Section 203 of the Delaware General Corporation Law (the "Anti-
Takeover Law") regulating corporate takeovers. The Anti-Takeover Law prevents
certain Delaware corporations, including those whose securities are listed on
the Nasdaq National Market, from engaging, under certain circumstances, in a
"business combination" (which includes a merger or sale of more than 10% of
the corporation's assets) with any "interested stockholder" (a stockholder who
owns 15% or more of the corporation's outstanding voting stock, as well as
affiliates and associates of any such persons) for three years following the
date that such stockholder became an "interested stockholder" unless (i) the
transaction is approved by the Board of Directors prior to the date the
"interested stockholder" attained such status, (ii) upon consummation of the
transaction that resulted in the stockholder's becoming an "interested
stockholder," the "interested stockholder" owned at least 85% of the voting
stock of the corporation outstanding at the time the transaction commenced
(excluding those shares owned by (a) persons who are directors and also
officers and (b) employee stock plans in which employee participants do not
have the right to determine confidentially whether shares held subject to the
plan will be tendered in a tender or exchange offer), or (iii) on or
subsequent to such date the "business combination" is approved by the Board of
Directors and authorized at an annual or special meeting of stockholders by
the affirmative vote of at least two-thirds of the outstanding
 
                                      67
<PAGE>
 
voting stock that is not owned by the "interested stockholder." A Delaware
corporation may "opt out" of the Anti-Takeover Law with an express provision
in its original certificate of incorporation or an express provision in its
certificate of incorporation or bylaws resulting from a stockholders'
amendment approved by at least a majority of the outstanding voting shares.
The Company has not "opted out" of the provisions of the Anti-Takeover Law.
The statute could prohibit or delay mergers or other takeover or change-in-
control attempts with respect to the Company and, accordingly, may discourage
attempts to acquire the Company.
 
  The Company's Amended and Restated Bylaws, which will be in effect upon the
completion of this offering, will provide for the division of the Board into
three classes as nearly equal in size as possible with staggered three-year
terms. The classification of the Board could have the effect of making it more
difficult for a third party to acquire, or of discouraging a third party from
acquiring, control of the Company. In addition, the Amended and Restated
Bylaws will provide that any action required or permitted to be taken by the
stockholders of the Company at an annual meeting or special meeting of
stockholders may only be taken if it is properly brought before such meeting
and may not be taken by written action in lieu of a meeting. The Amended and
Restated Bylaws will provide that special meetings of the stockholders may
only be called by the Chairman of the Board, the Chief Executive Officer or,
if none, the President of the Company or by the Board.
 
  The Company's Amended and Restated Certificate of Incorporation and Amended
and Restated Bylaws will provide that the Company will indemnify officers and
directors against losses that they may incur in investigations and legal
proceedings resulting from their services to the Company, which may include
services in connection with takeover defense measures. Such provisions may
have the effect of preventing changes in the management of the Company.

                        SHARES ELIGIBLE FOR FUTURE SALE
 
  Prior to this offering, there has been no public market for the Common Stock
of the Company. Future sales of substantial amounts of Common Stock in the
public market could adversely affect prevailing market prices from time to
time. Furthermore, since no shares will be available for sale shortly after
this offering because of certain contractual and legal restrictions on resale
(as described below), sales of substantial amounts of Common Stock of the
Company in the public market after these restrictions lapse could adversely
affect the prevailing market price and the ability of the Company to raise
equity capital in the future.
 
  Upon completion of this offering, the Company will have outstanding an
aggregate of            shares of Common Stock, assuming no exercise of the
Underwriters' over-allotment option and no exercise of outstanding options. Of
these shares, all of the shares sold in this offering will be freely tradable
without restriction or further registration under the Securities Act, unless
such shares are purchased by "affiliates" of the Company as that term is
defined in Rule 144 under the Securities Act (the "Affiliates"). The remaining
17,018,509 shares of Common Stock held by existing stockholders are
"restricted securities" as that term is defined in Rule 144 under the
Securities Act ("Restricted Shares"). Restricted Shares may be sold in the
public market only if registered or if they qualify for an exemption from
registration under Rule 144 or 701 promulgated under the Securities Act, which
rules are summarized below. All officers, directors, stockholders and option
holders of the Company have agreed not to offer, pledge, sell, contract to
sell, sell any option or contract to purchase, purchase any option or contract
to sell, grant any option, right or warrant to purchase, or otherwise transfer
or dispose of, directly or indirectly (or enter into any swap or other
arrangement that transfers to another, in whole or in part, any of the
economic consequences of ownership of), any shares of Common Stock or any
securities convertible into or exercisable or exchangeable for shares of
Common Stock, for a period of 180 days after the date of this Prospectus,
without the prior written consent of Morgan Stanley & Co. Incorporated. Morgan
Stanley & Co. Incorporated may in its sole discretion choose to release a
certain number of these shares from such restrictions prior to the expiration
of such 180 day period. As a result of such contractual restrictions and the
provisions of Rule 144 and 701, the Restricted Shares will be available for
sale in the public market as follows: (i) no shares will be eligible for
immediate sale on the date of this Prospectus; (ii) 16,668,509 shares will be
eligible for sale upon expiration of the lock-up agreements 180 days after the
date of this Prospectus, subject in the case of all but 2,661,052 shares to
the volume limitations and other conditions of Rule 144 described below; and
(iii) the remaining 350,000 shares will become eligible for sale in November
1998, subject to the volume limitations and other conditions of Rule 144.
 
  In general, under Rule 144 as currently in effect, beginning 90 days after
the date of this Prospectus, a person (or persons whose shares are aggregated)
who has beneficially owned Restricted Shares for at least one year (including
the holding period of any prior owner except an Affiliate) would be entitled
to sell within any three-month period a number of shares that does not exceed
the greater of: (i) 1% of the number of shares of Common Stock then
outstanding (which will equal approximately          shares immediately after
this offering); or (ii) the average weekly trading volume of the Common Stock
on the Nasdaq National Market during the four calendar weeks preceding the
filing of a notice on Form 144 with respect to such sale. Sales under Rule 144
are also subject to certain manner of sale provisions and notice requirements
and to the availability of current public information about the Company. Under
Rule 144(k), a person who is not deemed to have been an Affiliate of the
Company at any time during the 90 days preceding a sale, and who has
beneficially owned the shares proposed to be sold for at least two years
(including the holding period of any prior owner except an Affiliate), is
entitled to sell such shares without complying with the manner of sale, public
information, volume limitation or notice provisions of Rule 144; therefore,
unless otherwise restricted, shares will qualify as "144(k) shares" on the
date of this Prospectus and may be sold immediately upon the completion of
this offering. Subject to certain limitations on the aggregate offering price
of a transaction and other conditions, employees, directors, officers,
consultants or advisors may rely on Rule 701 with respect to the resale of
securities originally purchased from the Company prior to the date the issuer
becomes subject to the reporting requirements of the Securities Exchange Act
of 1934, as amended (the "Exchange Act"), pursuant to written compensatory
benefit plans or written contracts relating to the compensation of such
persons. In addition, the Securities and Exchange Commission has indicated
that Rule 701 will apply to typical stock options granted by an issuer before
it
 
                                      69
<PAGE>
 
becomes subject to the reporting requirements of the Exchange Act, along with
the shares acquired upon exercise of such options (including exercises after
the date of this Prospectus). Securities issued in reliance on Rule 701 are
restricted securities and, subject to the contractual restrictions described
above, beginning 90 days after the date of this Prospectus, may be sold by
persons other than Affiliates subject only to the manner of sale provisions of
Rule 144, and by Affiliates under Rule 144 without compliance with its holding
period requirements.
 
  Upon completion of this offering, the holders of approximately 14,719,339
shares of Common Stock currently outstanding or issuable upon conversion of
Preferred Stock, or their transferees, will be entitled to certain rights with
respect to the registration of such shares under the Securities Act. See
"Description of Capital Stock--Registration Rights." Registration of such
shares under the Securities Act would result in such shares becoming freely
tradable without restriction under the Securities Act (except for share
purchases by affiliates) immediately upon the effectiveness of such
registration.
   
  The Company intends to file a registration statement under the Securities
Act covering (i) 2,625,000 shares of Common Stock reserved or to be reserved
for issuance under the Equity Incentive Plan, the Purchase Plan and the
Directors Plan, (ii) an additional number of shares of Common Stock to be
reserved for issuance under the Equity Incentive Plan equal to the number of
shares reserved for future issuance under the Prior Plans as of the date of
this Prospectus (717,482 as of October 31, 1997), and (iii) shares subject to
outstanding options under the Prior Plans as of the date of this Prospectus
(2,362,528 as of October 31, 1997). See "Management--Employee Benefit Plans."
Such registration statement is expected to be filed and become effective as
soon as practicable after the effective date of this offering. Accordingly,
shares registered under such registration statement will, subject to Rule 144
volume limitations applicable to Affiliates, be available for sale in the open
market, beginning 180 days after the date of the Prospectus, unless such
shares are subject to vesting restrictions with the Company.

  The Underwriting Agreement provides that the obligations of the several
Underwriters to pay for and accept delivery of the shares of Common Stock
offered hereby are subject to the approval of certain legal matters by their
counsel and to certain other conditions. The Underwriters are obligated to
take and pay for all of the shares of Common Stock offered hereby (other than
those covered by the over-allotment option described below) if any such shares
are taken.
 
  The Underwriters initially propose to offer part of the shares of Common
Stock directly to the public at the initial public offering price set forth on
the cover page hereof and part to certain dealers at a price that represents a
concession not in excess of $   a share under the public offering price. Any
Underwriter may allow, and such dealers may reallow, a concession not in
excess of $   a share to other Underwriters or to certain dealers. After the
initial offering of the shares of Common Stock, the offering price and other
selling terms may from time to time be varied by the Representatives.
 
  The Company has granted to the Underwriters an option, exercisable for 30
days from the date of this Prospectus, to purchase up to an aggregate of
         additional shares of Common Stock at the initial public offering
price set forth on the cover page hereof, less underwriting discounts and
commissions. The Underwriters may exercise such option to purchase solely for
the purpose of covering over-allotments, if any, made in connection with the
offering of the shares of Common Stock offered hereby. To the extent such
option is exercised, each Underwriter will become obligated, subject to
certain conditions, to purchase approximately the same percentage of such
additional shares of Common Stock as the number set forth next to such
Underwriter's name in the preceding table bears to the total number of shares
of Common Stock set forth next to the names of all Underwriters in the
preceding table.
 
  The Underwriters have informed the Company that they do not intend sales to
discretionary accounts to exceed five percent of the total number of shares of
Common Stock offered by them.
 
  The Company has applied to list its Common Stock on the Nasdaq National
Market under the symbol "VRSN."
 
  Each of the Company and the directors, executive officers, certain other
stockholders and option holders of the Company has agreed that, without the
prior written consent of Morgan Stanley & Co. Incorporated on behalf of the
Underwriters, it will not during the period ending 180 days after the date of
this Prospectus (i) offer, pledge, sell, contract to sell, sell any option or
contract to purchase, purchase any option or contract to sell, grant any
option, right or warrant to purchase or otherwise transfer, lend or dispose
of, directly or indirectly, any shares
 
                                      71
<PAGE>
 
of Common Stock or any securities convertible into or exercisable or
exchangeable for Common Stock or (ii) enter into any swap or other arrangement
that transfers to another, in whole or in part, any of the economic
consequences of ownership of the Common Stock, whether any such transaction
described in clause (i) or (ii) above is to be settled by delivery of Common
Stock or such other securities, in cash or otherwise, except under certain
limited circumstances. The restrictions described in this paragraph to not
apply to (a) the sale of Shares to the Underwriters, (b) the issuance by the
Company of shares of Common Stock upon exercise of an option or a warrant
outstanding on the date of this Prospectus and described as such in the
Prospectus, (c) the issuance by the Company of shares of Common Stock under
the Equity Incentive Plan, the Directors Plan and the Purchase Plan or (d)
transactions by any person other than the Company relating to shares of Common
Stock or other securities acquired in open market transactions after the
completion of the offering of the Shares.
 
  In order to facilitate the offering of the Common Stock, the Underwriters
may engage in transactions that stabilize, maintain or otherwise affect the
price of the Common Stock. Specifically, the Underwriters may over-allot in
connection with the offering, creating a short position in the Common Stock
for their own account. In addition, to cover over-allotments or to stabilize
the price of the Common Stock, the Underwriters may bid for, and purchase,
shares of Common Stock in the open market. Finally, the underwriting syndicate
may reclaim selling concessions allowed to an Underwriter or a dealer for
distributing the Common Stock in the offering, if the syndicate repurchases
previously distributed Common Stock in transactions to cover syndicate short
positions, in stabilization transactions or otherwise. Any of these activities
may stabilize or maintain the market price of the Common Stock above
independent market levels. The Underwriters are not required to engage in
these activities, and may end any of these activities at any time.
 
  In November and December 1996, the Company issued an aggregate of 3,625,000
shares of Series C Preferred Stock for an aggregate consideration of $29.0
million. In connection with such financing, Morgan Stanley & Co. Incorporated
received an aggregate of $730,000 as a financial advisory fee.
 
  The Company and the Underwriters have agreed to indemnify each other against
certain liabilities, including liabilities under the Securities Act.
 
PRICING OF THE OFFERING
 
  Prior to this offering, there has been no public market for the Common Stock
or any other securities of the Company. The initial public offering price for
the Common Stock will be determined by negotiations between the Company and
the Representatives. Among the factors to be considered in determining the
initial public offering price will be the future prospects of the Company and
its industry in general, sales, earnings and certain other financial and
operating information of the Company in recent periods, and the price-earnings
ratios, price-sales ratios, market prices of securities and certain financial
and operating information of companies engaged in activities similar to those
of the Company. The estimated initial public offering price range set forth on
the cover page of this Preliminary Prospectus is subject to change as a result
of market conditions and other factors.

                         INDEPENDENT AUDITORS' REPORT
 
The Board of Directors and Stockholders
VeriSign, Inc.:
 
  We have audited the accompanying consolidated balance sheets of VeriSign,
Inc. and subsidiary as of December 31, 1995 and 1996 and September 30, 1997,
and the related consolidated statements of operations, stockholders' equity,
and cash flows for the period from April 12, 1995 (inception) to December 31,
1995, for the year ended December 31, 1996, and for the nine months ended
September 30, 1997. These consolidated financial statements are the
responsibility of the Company's management. Our responsibility is to express
an opinion on these consolidated financial statements based on our audits.
 
  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
 
  In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of VeriSign,
Inc. and subsidiary as of December 31, 1995 and 1996 and September 30, 1997,
and the results of their operations and their cash flows for the period from
April 12, 1995 (inception) to December 31, 1995, for the year ended December
31, 1996, and for the nine months ended September 30, 1997, in conformity with
generally accepted accounting principles.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
               DECEMBER 31, 1995 AND 1996 AND SEPTEMBER 30, 1997
 (INFORMATION FOR THE NINE-MONTH PERIOD ENDED SEPTEMBER 30, 1996 IS UNAUDITED)
 
(1) DESCRIPTION OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
   
  VeriSign, Inc. (the "Company") was incorporated in Delaware in April 1995
when RSA Data Security, Inc. ("RSA") contributed equipment, other assets, and
technology for common stock. This transfer of nonmonetary assets was recorded
at the founder's historical cost basis. The Company provides digital
certificate solutions and infrastructure needed by companies, government
agencies, trading partners and individuals to conduct trusted and secure
communications and commerce over the Internet and over intranets and extranets
using the Internet Protocol.     
 
  Consolidation
 
  In February 1996, the Company established a subsidiary in Japan. As of
September 30, 1997, the Company owned approximately 51% of the subsidiary's
outstanding shares of capital stock. The subsidiary provides the Company's
digital certificate solutions throughout Japan. The accompanying consolidated
financial statements include the accounts of the Company and its subsidiary.
All significant intercompany balances and transactions have been eliminated in
consolidation. The Company accounts for changes in its proportionate share of
the net assets of the subsidiary resulting from sales of capital stock by the
subsidiary as equity transactions.
 
  Foreign Currency Translation
   
  The functional currency for the Company's subsidiary is the U.S. dollar;
however, its books of record are maintained in Japanese yen. As a result, its
financial statements are remeasured into U.S. dollars using a combination of
current and historical exchange rates and any remeasurement adjustments are
included in net loss, along with all transaction gains and losses for the
period.     
 
  Cash, Cash Equivalents, and Short-Term Investments
 
  The Company considers all highly liquid investments with maturities of three
months or less at the date of acquisition to be cash equivalents. Cash and
cash equivalents include money market funds, commercial paper, and various
deposit accounts.
 
  Investments held by the Company are classified as "available-for-sale" and
are carried at fair value based on quoted market prices. Such investments
consist of U.S. government or agency securities and corporate bonds with
original maturities beyond 3 months and less than 12 months. Unrealized gains
and losses as of December 31, 1996, and September 30, 1997, and realized gains
and losses for the year ended December 31, 1996 and for the nine months ended
September 30, 1997, were not material.
 
  Property and Equipment
 
  Property and equipment are stated at cost less accumulated depreciation.
Depreciation is calculated using the straight-line method over the estimated
useful lives of the assets, generally three to five years.
 
  Revenue Recognition
 
  Revenues from the sale or renewal of digital certificates are deferred and
recognized ratably over the life of the digital certificate, generally 12
months. Revenues from services are recognized using the percentage-of-
completion method, based on the ratio of costs incurred to total estimated
costs for fixed-fee development arrangements, on a time-and-materials basis
for consulting and training services or ratably over the term of the agreement
for support and maintenance services. To the extent costs incurred and
anticipated costs to complete

                         VERISIGN, INC. AND SUBSIDIARY
 
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
fixed-fee contracts in progress exceed anticipated billings, a loss is accrued
for the excess. To date, the Company has not experienced such losses. Deferred
revenue principally consists of payments for unexpired digital certificates.
 
  In October 1997, the American Institute of Certified Public Accountants
issued Statement of Position ("SOP") No. 97-2, Software Revenue Recognition,
which supersedes SOP No. 91-1. The Company will be required to adopt SOP No.
97-2 prospectively for software transactions entered into beginning January 1,
1998. SOP No. 97-2 generally requires revenue earned on software arrangements
involving multiple elements to be allocated to each element based on the
relative fair values of the elements. The fair value of an element must be
based on evidence that is specific to the vendor. If a vendor does not have
evidence of the fair value for all elements in a multiple-element arrangement,
all revenue from the arrangement is deferred until such evidence exists or
until all elements are delivered. The Company's management anticipates that
the adoption of SOP No. 97-2 will not have a material effect on the Company's
operating results.
 
  Research and Development Costs
 
  Research and development costs are expensed as incurred. Costs incurred
subsequent to establishing technological feasibility, in the form of a working
model, are capitalized and amortized over their estimated useful lives. To
date, software development costs incurred after technological feasibility has
been established have not been material.
 
  Income Taxes
 
  The Company uses the asset and liability method to account for income taxes.
Deferred tax assets and liabilities are recognized for the future tax
consequences attributable to differences between the financial statement
carrying amounts of existing assets and liabilities and their respective tax
bases. Deferred tax assets and liabilities are measured using enacted tax
rates expected to apply to taxable income in the years 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
income in the period that includes the enactment date. A valuation allowance
is recorded for deferred tax assets whose realization is not sufficiently
likely.
 
  Stock-Based Compensation
 
  The Company accounts for its equity-based compensation plan using the
intrinsic value method.
 
  Pro Forma Net Loss Per Share
 
  Pro forma net loss per share is computed using the weighted average number
of shares of common stock and convertible preferred stock outstanding on an
as-if converted basis and, when dilutive, common equivalent shares from
options to purchase common stock using the treasury stock method. In
accordance with certain Securities and Exchange Commission Staff Accounting
Bulletins, such computations included all common and common equivalent shares
issued within the 12 months preceding the initial public offering ("IPO") date
as if they were outstanding for all prior periods presented using the treasury
stock method and the estimated IPO price.
 
  The Financial Accounting Standards Board recently issued Statement of
Financial Accounting Standards ("SFAS") No. 128, Earnings Per Share, which
must be adopted in the first quarter of 1998. At that time, the Company will
be required to change the method currently used to compute net income (loss)
per share and to restate amounts previously reported. Under the new
requirements, basic net income (loss) per share is computed using the weighted
average number of shares of common stock outstanding during the period and
diluted net income (loss) per share is computed in a manner similar to the
Company's existing policy. The Company expects that neither basic nor diluted
net loss per share will differ materially from pro forma net loss per share
presented in the accompanying consolidated financial statements.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
          
  Concentration of Credit Risk and Related Party Transactions     
 
  Financial instruments that potentially subject the Company to significant
concentrations of credit risk consist principally of cash, cash equivalents,
short-term investments, and accounts receivable. The Company maintains its
cash, cash equivalents, and short-term investments with high quality financial
institutions and, as part of its cash management process, performs periodic
evaluations of the relative credit standing of these financial institutions.
The Company also performs ongoing credit evaluations of its customers and,
generally, requires no collateral from its customers. The Company maintains an
allowance for potential credit losses, but to date has not experienced
significant write-offs.
   
  The Company provided services to VISA International Services Association
("VISA"), a 6% stockholder of the Company on a fully-diluted basis, under an
agreement that included development and ongoing operations of a digital
certificate system for VISA's member banks. VISA accounted for approximately
21% and 16% of the Company's revenues for the year ended December 31, 1996,
and the nine months ended September 30, 1997, respectively, and 13% and 25% of
accounts receivable as of December 31, 1996, and September 30, 1997,
respectively.     
   
  The Company entered into a development agreement in September 1997 with
Security Dynamics Technologies, Inc. ("Security Dynamics"), the parent company
of RSA, a 27% stockholder of the Company on a fully-diluted basis, to develop
a customized certificate authority product in order to enable Security
Dynamics to offer a product with encryption and digital certificate authority
functionality. The development agreement provides that Security Dynamics will
pay the Company an aggregate of $2.7 million as an initial license fee,
$900,000 of which was paid in October 1997 and the remainder of which will be
payable upon the achievement of certain milestones. The Company records
revenue related to the development agreement using the percentage-of-
completion method. Revenue from the development agreement accounted for
approximately 4% of the Company's revenues for the nine months ended
September 30, 1997.     
   
  The Company had one customer, a South African systems integrator, and
another customer, a financial services provider, which accounted for
approximately 28% and 13%, respectively, of accounts receivable as of December
31, 1996. One other customer, a European smart card manufacturer, accounted
for approximately 12% of accounts receivable as of September 30, 1997.     
 
  Use of Estimates
 
  The preparation of consolidated financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the
consolidated financial statements and reported amounts of revenues and
expenses during the reporting period. Actual results could differ from those
estimates.
 
  Unaudited Pro Forma Consolidated Balance Sheet
   
  Upon closing of the Company's proposed initial public offering, all
outstanding shares of preferred stock will be converted into 10,031,006 shares
of common stock. The unaudited pro forma consolidated balance sheet as of
September 30, 1997, reflects this conversion and also gives effect to the
issuance of 250,000 shares of common stock from the litigation settlement
described in Note 8.     
 
  Interim Financial Statements
 
  The accompanying unaudited consolidated financial statements for the nine-
month period ended September 30, 1996, have been prepared on substantially the
same basis as the audited consolidated financial statements and include all
adjustments, consisting only of normal recurring adjustments, necessary for a
fair presentation of the consolidated financial information set forth therein.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
  Section 145 of the Delaware General Corporation Law authorizes a court to
award, or a corporation's Board of Directors to grant, indemnity to directors
and officers in terms sufficiently broad to permit such indemnification under
certain circumstances for liabilities (including reimbursement for expenses
incurred) arising under the Securities Act of 1933, as amended (the
"Securities Act").
 
  As permitted by the Delaware General Corporation Law, the Registrant's Third
Amended and Restated Certificate of Incorporation, which will become effective
upon the completion of this offering, includes a provision that eliminates the
personal liability of its directors for monetary damages for breach of
fiduciary duty as a director, except for liability (i) for any breach of the
director's duty of loyalty to the Registrant or its stockholders, (ii) for
acts or omissions not in good faith or that involve intentional misconduct or
a knowing violation of law, (iii) under section 174 of the Delaware General
Corporation Law (regarding unlawful dividends and stock purchases) or (iv) for
any transaction from which the director derived an improper personal benefit.
 
  As permitted by the Delaware General Corporation Law, the Registrant's
Amended and Restated Bylaws, which will become effective upon the completion
of this offering, provide that (i) the Registrant is required to indemnify its
directors and officers to the fullest extent permitted by the Delaware General
Corporation Law, subject to certain very limited exceptions, (ii) the
Registrant may indemnify its other employees and agents to the extent that it
indemnifies its officers and directors, unless otherwise required by law, its
Certificate of Incorporation, its Amended and Restated Bylaws, or agreement,
(iii) the Registrant is required to advance expenses, as incurred, to its
directors and executive officers in connection with a legal proceeding to the
fullest extent permitted by the Delaware General Corporation Law, subject to
certain very limited exceptions and (iv) the rights conferred in the Amended
and Restated Bylaws are not exclusive.
 
  The Registrant has entered into Indemnification Agreements with each of its
current directors and certain of its executive officers and intends to enter
into such Indemnification Agreements with each of its other executive officers
to give such directors and executive officers additional contractual
assurances regarding the scope of the indemnification set forth in the
Registrant's Certificate of Incorporation and to provide additional procedural
protections. At present, there is no pending litigation or proceeding
involving a director, officer or employee of the Registrant regarding which
indemnification is sought, nor is the Registrant aware of any threatened
litigation that may result in claims for indemnification.
 
                                     II-1
<PAGE>
 
  Reference is also made to Article VIII of the Underwriting Agreement, which
provides for the indemnification of officers, directors and controlling
persons of the Registrant against certain liabilities. The indemnification
provisions in the Registrant's Certificate of Incorporation, Amended and
Restated Bylaws and the Indemnification Agreements entered into between the
Registrant and each of its directors and executive officers may be
sufficiently broad to permit indemnification of the Registrant's directors and
executive officers for liabilities arising under the Securities Act.
 
  The Registrant, with approval by the Registrant's Board of Directors, has
applied for, and expects to obtain, directors' and officers' liability
insurance.

Registration Statement regarding relevant indemnification provisions described
above and elsewhere herein:

ITEM 17. UNDERTAKINGS.
 
  The undersigned Registrant hereby undertakes to provide to the Underwriters
at the closing specified in the Underwriting Agreement certificates in such
denominations and registered in such names as required by the Underwriters to
permit prompt delivery to each purchaser.
 
  Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the provisions described under Item 14 above, or
otherwise, the Registrant has been advised that in the opinion of the
Securities and Exchange Commission such indemnification is against public
policy as expressed in the Securities Act and is, therefore, unenforceable. In
the event that a claim for indemnification against such liabilities (other
than the payment by the Registrant of expenses incurred or paid by a director,
officer or controlling person of the Registrant in the successful defense of
any action, suit or proceeding) is asserted by such director, officer or
controlling person in connection with the securities being registered, the
Registrant will, unless in the opinion of its counsel the matter has been
settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act and will be governed by the final
adjudication of such issue.
 
  The undersigned Registrant hereby undertakes that:
 
  (1) For purposes of determining any liability under the Securities Act, the
information omitted from the form of prospectus filed as part of this
Registration Statement in reliance upon Rule 430A and contained in a form of
prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4) or 497(h)
under the Securities Act shall be deemed to be part of this Registration
Statement as of the time it was declared effective.
 
  (2) For the purpose of determining any liability under the Securities Act,
each post-effective amendment that contains a form of prospectus shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to
be the initial bona fide offering thereof.

                             AMENDED AND RESTATED

                        CERTIFICATE OF INCORPORATION OF

                                VERISIGN, INC.

                            a Delaware corporation

                                        

     ONE:  The name of the corporation is VeriSign, Inc. (hereinafter sometimes
referred to as the "Corporation").

     TWO:  The address of the Corporation's registered office in the State of
Delaware is 30 Old Rudnick Lane, in the City of Dover, in the County of Kent.
The registered agent in charge thereof is CorpAmerica, Inc., 30 Old Rudnick
Lane, Dover, Delaware 19901.

     THREE:    The purpose of the Corporation is to engage in any lawful act or
activity for which corporations may be organized under the General Corporation
law of Delaware.

     FOUR: A.  The Corporation is authorized to issue two classes of stock to be
designated, respectively, "Common Stock" and "Preferred Stock."  The total
number of shares which the Corporation is authorized to issue is fifty-five
Million (55,000,000) shares.  Fifty Million (50,000,000) shares shall be Common
Stock, $0.001 par value per share, and five Million (5,000,000) shares shall be
Preferred Stock, $0.001 par value per share.

           B.  The Board of Directors is authorized, subject to any limitations
prescribed by law, to provide for the issuance of shares of Preferred Stock in
series, and by filing a certificate pursuant to the applicable law of the State
of Delaware (such certificate being hereinafter referred to as a "Preferred
Stock Designation"), to establish from time to time the number of shares to be
included in each such series, and to fix the designation, powers, preferences,
and rights of each such series and any qualifications, limitations or
restrictions thereof.  The number of authorized shares of Preferred Stock may be
increased or decreased (but not below the number of shares thereof then
outstanding) by the affirmative vote of the holders of a majority of the
outstanding shares of Common Stock, without a vote of the holders of the
Preferred Stock, or of any series thereof, unless a vote of any such holders is
required pursuant to the terms of any Preferred Stock Designation.

     FIVE: The following provisions are inserted for the management of the
business and the conduct of the affairs of the Corporation, and for further
definition, limitation and regulation of the powers of the Corporation and of
its directors and stockholders:

           A.  The business and affairs of the Corporation shall be managed by
or under the direction of the Board of Directors. In addition to the powers and
authority expressly conferred upon them by statute or by this Third Amended and
Restated Certificate of Incorporation or the Bylaws of the Corporation, the
directors are hereby empowered to exercise all such powers and do all such acts
and things as may be exercised or done by the Corporation.

           B.  The directors of the Corporation need not be elected by written
ballot unless the Bylaws so provide.
<PAGE>
 
          C.    Any action required or permitted to be taken by the stockholders
of the Corporation must be effected at a duly called annual or special meeting
of stockholders of  the Corporation and may not be effected by any consent in
writing by such stockholders.

          D.    Special meetings of stockholders of the Corporation may be
called only by either the Board of Directors pursuant to a resolution adopted by
a majority of the total number of authorized directors (whether or not there
exist any vacancies in previously authorized directorships at the time any such
resolution is presented to the Board for adoption), the Chief Executive Officer
or the President.

    SIX:  A.    The directors, other than those who may be elected by the
holders of Preferred Stock under specified circumstances, shall be divided into
three classes with the term of office of the first class (Class I) to expire at
the annual meeting of the stockholders held in 1998; the term of office of the
second class (Class II) to expire at the annual meeting of stockholders held in
1999; the term of office of the third class (Class III) to expire at the annual
meeting of stockholders held in 2000; and thereafter for each such term to
expire at each third succeeding annual meeting of stockholders after such
election. All directors shall hold office until the expiration of the term for
which elected, and until their respective successors are elected, except in the
case of the death, resignation, or removal of any director.

          B.    Subject to the rights of the holders of any series of Preferred
Stock then outstanding, newly created directorships resulting from any increase
in the authorized number of directors or any vacancies in the Board of Directors
resulting from death, resignation or other cause may be filled (a) by the
stockholders at any meeting, (b) by a majority of the directors, although less
than a quorum, or (c) by a sole remaining director, and directors so chosen
shall hold office for a term expiring at the next annual meeting of stockholders
at which the term of office of the class to which they have been elected
expires, and until their respective successors are elected, except in the case
of the death, resignation, or removal of any director.  No decrease in the
number of directors constituting the Board of Directors shall shorten the term
of any incumbent director.

     SEVEN:     The Corporation shall have a perpetual existence.

     EIGHT: A.  Exculpation.  A director of the Corporation shall not be
                -----------                                             
personally liable to the Corporation or its stockholders for monetary damages
for breach of fiduciary duty as a director, except for liability (i) for any
breach of the director's duty of loyalty to the Corporation or its stockholders,
(ii) for acts or omissions not in good faith or which involve intentional
misconduct or a knowing violation of law, (iii) under Section 174 of the
Delaware General Corporation law or (iv) for any transaction from which the
director derived any improper personal benefit.  If the Delaware General
Corporation law is hereafter amended to further reduce or authorize, with the
approval of the Corporation's stockholders, further reductions in the liability
of the Corporation's directors for breach of fiduciary duty, then a director of
the Corporation shall not be liable for any such breach to the fullest extent
permitted by the Delaware General Corporation Law as so amended.

            B.  Indemnification.  To the extent permitted by applicable law,
                ---------------
this Corporation is also authorized to provide indemnification of (and
advancement of expenses to) agents (and any other persons to which Delaware law
permits this Corporation to provide 
<PAGE>
 
indemnification) through bylaw provisions, agreements with such agents or other
persons, vote of stockholders or disinterested directors or otherwise, in excess
of the indemnification and advancement otherwise permitted by Section 145 of the
Delaware General Corporation Law, subject only to limits created by applicable
Delaware law (statutory or non-statutory), with respect to actions for breach of
duty to the Company, its stockholders, and others.

          C.  Effect of Repeal or Modification.  Any repeal or modification of
              --------------------------------                                
any of the foregoing provisions of this Article Eight shall not adversely affect
any right or protection of a director, officer, agent or other person existing
at the time of, or increase the liability of any director of the Corporation
with respect to any acts or omissions of such director occurring prior to, such
repeal or modification.

                                  Stockholders


     Section 1.  Annual Meeting.  An annual meeting of the stockholders of the
     ----------  --------------                                               
corporation, for the election of the Directors to succeed those whose terms
expire and for the transaction of such other business as may properly come
before the meeting, shall be held at such place, on such date and at such time
as the Board of Directors shall each year fix.

     Section 2.  Special Meetings.  Special meetings of the stockholders, for
     ----------  ----------------                                            
any purpose or purposes prescribed in the notice of the meeting, may be called
only by (i) the Board of Directors pursuant to a resolution adopted by a
majority of the total number of authorized directors (whether or not there exist
any vacancies in previously authorized directorships at the time any such
resolution is presented to the Board of Directors for adoption), (ii) the
Chairman of the Board or (iii) the President and shall be held at such place, on
such date, and at such time as they shall fix.  Business transacted at special
meetings shall be confined to the purpose or purposes stated in the notice.

     Section 3.  Place of Meetings.  All meetings of stockholders shall be held
     ----------  -----------------                                             
at the principal office of the corporation unless a different place is fixed by
the person or persons calling the meeting and stated in the notice of the
meeting.

     Section 4.  Notices of Meetings and Adjourned Meetings.  A written notice
     ----------  ------------------------------------------                   
of each annual or special meeting of the stockholders stating the place, date,
and hour thereof, shall be given by the Secretary (or the person or persons
calling the meeting), not less than 10 nor more than 60 days before the date of
the meeting, to each stockholder entitled to vote thereat, by leaving such
notice with him or her or at his or her residence or usual place of business, or
by depositing it postage prepaid in the United States mail, directed to each
stockholder at his or her address as it appears on the records of the
corporation.  Notices of all meetings of stockholders shall state the purpose or
purposes for which the meeting is called.  An affidavit of the Secretary,
Assistant Secretary, or transfer agent of the corporation that the notice has
been given shall, in the absence of fraud, be primary facie evidence of the
facts stated therein.  No notice need be given to any person with whom
communication is unlawful or to any person who has waived such notice either (a)
in writing (which writing need not specify the business to be transacted at, or
the purpose of, the meeting) signed by such person before or after the time of
the meeting or (b) by attending the meeting except for the express purpose of
objecting, at the beginning of the meeting, to the transaction of any business
because the meeting is not lawfully called or convened.  When a meeting is
adjourned to another time and place, notice need not be given of the adjourned
meeting if the time and place thereof are announced at the meeting at which the
<PAGE>
 
adjournment is taken except that, if the adjournment is for more than 30 days or
if, after the adjournment, a new record date is fixed for the adjourned meeting,
a notice of the adjourned meeting shall be given in the manner provided in this
Section 4.

     Section 5.  Quorum.  At any meeting of the stockholders, a quorum for the
     ----------  ------                                                       
transaction of business shall consist of one or more individuals appearing in
person or represented by proxy and owning or representing a majority of the
shares of the corporation then outstanding and entitled to vote thereat, unless
or except to the extent that the presence of a larger number may be required by
law (including as required from time to time by the Delaware General Corporation
Law or the Certificate of Incorporation of the corporation).  Where a separate
vote by a class or classes is required, a majority of the shares of such class
or classes then outstanding and entitled to vote present in person or by proxy
shall constitute a quorum entitled to take action with respect to that vote on
that matter.  If a quorum shall fail to attend any meeting, the chairman of the
meeting or the holders of a majority of the shares of stock entitled to vote
thereat who are present, in person or by proxy, may adjourn the meeting to
another place, date, or time.

     Section 6.  Organization.  Such person as the Board of Directors may have
     ----------  ------------                                                 
designated or, in the absence of such a person, the President of the corporation
shall call to order any meeting of the stockholders and act as chairman of the
meeting.  In the absence of the Secretary of the corporation, the secretary of
the meeting shall be such person as the chairman appoints.

     Section 7.  Conduct of Business.  The chairman of any meeting of
     ----------  -------------------                                 
stockholders shall determine the order of business and the procedure at the
meeting, including such regulation of the manner of voting and the conduct of
discussion as seem to him or her in order.

     Section 8.  Voting.  Unless otherwise provided in the Certificate of
     ----------  ------                                                  
Incorporation as currently in effect (the "Certificate of Incorporation") and
subject to the provisions of Section 6 of Article IV hereof, each stockholder
shall have one vote for each share of stock entitled to vote held by him or her
of record according to the records of the corporation.  Persons holding stock in
a fiduciary capacity shall be entitled to vote the shares so held.  Persons
whose stock is pledged shall be entitled to vote unless the pledgor in a
transfer on the books of the corporation has expressly empowered the pledgee to
vote the pledged shares, in which case only the pledgee or his or her proxy
shall be entitled to vote.  If shares stand of record in the names of two or
more persons or if two or more persons have the same fiduciary relationship
respecting the shares then, unless the Secretary is given written notice to the
contrary and is furnished with a copy of the instrument or order appointing them
or creating the relationship wherein it is so provided to the contrary: (a) if
only one votes, his or her act binds all; (b) if more than one vote, the act of
the majority so voting binds all; and (c) if more than one vote and the vote is
evenly split, the effect shall be as provided by law.

     Section 9.  Proxies.  Each stockholder entitled to vote at a meeting of
     ----------  -------                                                    
stockholders may authorize another person or any group of persons to act for him
or her by proxy, but no such proxy shall be voted or acted upon after three
years from its date, unless the proxy provides for a longer period.

     Section 10.  Action at Meeting.  When a quorum is present at any meeting,
     -----------  -----------------                                           
action of the stockholders on any matter properly brought before such meeting,
other than the election of 

                                       2
<PAGE>
 
directors, shall require, and may be effected by, the affirmative vote of the
holders of a majority in interest of the stock present or represented by proxy
and entitled to vote on the subject matter, except where a different vote is
expressly required by law, the Certificate of Incorporation or these Bylaws, in
which case such express provision shall govern and control. The election of
directors shall be determined by a plurality of votes cast. If the Certificate
of Incorporation so provides, no ballot shall be required for the election of
directors unless requested by a stockholder present or represented at the
meeting and entitled to vote in the election.

     Section 11.  Stockholder Lists.  The officer who has charge of the stock
     -----------  -----------------                                          
ledger of the corporation shall prepare and make available, at least 10 days
before every meeting of stockholders, a complete list of stockholders entitled
to vote at the meeting, arranged in alphabetical order, and showing the address
of each stockholder and the number of shares registered in the name of each
stockholder.  Such list shall be open to the examination of any stockholder, for
any purpose germane to the meeting, during ordinary business hours, for a period
of at least 10 days prior to the meeting, either at a place of inspection within
the city where the meeting is to be held (which place of inspection shall be
specified in the notice of the meeting) or, if not so specified, at the place
where the meeting is to be held.  Such list shall also be produced and kept at
the time and place of the meeting during the whole time thereof, and may be
inspected by any stockholder who is present.  The stock ledger shall be the only
evidence as to who are the stockholders entitled to examine the stock ledger,
the list required by this section or the books of the corporation, or to vote in
person or by proxy at any meeting of stockholders.

     Section 12.  Inspectors of Elections.
     -----------  ----------------------- 

     (a) Applicability.  Unless otherwise provided in the Certificate of
         -------------                                                  
Incorporation or required by the Delaware General Corporation Law, the following
provisions of this Section 12 shall apply only if and when the corporation has a
class of voting stock that is:  (i) listed on a national securities exchange;
(ii) authorized for quotation on an interdealer quotation system of a registered
national securities association; or (iii) held of record by more than 2,000
stockholders; in all other cases, observance of the provisions of this Section
12 shall be optional, and at the discretion of the corporation.

     (b) Appointment.  The corporation shall, in advance of any meeting of
         -----------                                                      
stockholders, appoint one or more inspectors of election to act at the meeting
and make a written report thereof.  The corporation may designate one or more
persons as alternate inspectors to replace any inspector who fails to act.  If
no inspector or alternate is able to act at a meeting of stockholders, the
person presiding at the meeting shall appoint one or more inspectors to act at
the meeting.

     (c) Inspector's Oath.  Each inspector of election, before entering upon the
         ----------------                                                       
discharge of his duties, shall take and sign an oath faithfully to execute the
duties of inspector with strict impartiality and according to the best of his
ability.

     (d) Duties of Inspectors.  At a meeting of stockholders, the inspectors of
         --------------------                                                  
election shall (i) ascertain the number of shares outstanding and the voting
power of each share, (ii) determine the shares represented at a meeting and the
validity of proxies and ballots, (iii) count all votes 

                                       3
<PAGE>
 
and ballots, (iv) determine and retain for a reasonable period of time a record
of the disposition of any challenges made to any determination by the
inspectors, and (v) certify their determination of the number of shares
represented at the meeting, and their count of all votes and ballots. The
inspectors may appoint or retain other persons or entities to assist the
inspectors in the performance of the duties of the inspectors.

     (e)   Opening and Closing of Polls.  The date and time of the opening and
           ----------------------------
the closing of the polls for each matter upon which the stockholders will vote
at a meeting shall be announced by the inspectors at the meeting. No ballot,
proxies or votes, nor any revocations thereof or changes thereto, shall be
accepted by the inspectors after the closing of the polls unless the Court of
Chancery upon application by a stockholder shall determine otherwise.

     (f)   Determinations.  In determining the validity and counting of proxies
           --------------                                                      
and ballots, the inspectors shall be limited to an examination of the proxies,
any envelopes submitted with those proxies, any information provided in
connection with proxies in accordance with Section 212(c)(2) of the Delaware
General Corporation Law, ballots and the regular books and records of the
Corporation, except that the inspectors may consider other reliable information
for the limited purpose of reconciling proxies and ballots submitted by or on
behalf of banks, brokers, their nominees or similar persons which represent more
votes than the holder of a proxy is authorized by the record owner to cast or
more votes than the stockholder holds of record.  If the inspectors consider
other reliable information for the limited purpose permitted herein, the
inspectors at the time they make their certification of their determinations
pursuant to this Section 12 shall specify the precise information considered by
them, including the person or persons from whom they obtained the information,
when the information was obtained, the means by which the information was
obtained and the basis for the inspectors' belief that such information is
accurate and reliable.

preceding year's annual meeting (or, if the annual meeting is held more than

of the corporation not later than the close of business on the tenth (10th) day
following the day on which such public announcement is first made by the
corporation.


     (b) Special Meetings of Stockholders.  Only such business shall be
         --------------------------------                              
conducted at a special meeting of stockholders as shall have been brought before
the meeting pursuant to the corporation's notice of such meeting.  Nominations
of persons for election to the Board of Directors may be made at a special
meeting of stockholders at which directors are to be elected pursuant to the

Directors or (ii) provided that the Board of Directors has determined that
directors shall be elected at such meeting, by any stockholder of the
Corporation who is a stockholder of record at the time of giving of notice of
the special meeting, who shall be entitled to vote at the meeting and who
complies with the notice procedures set forth in this Section 13.  In the event
the Corporation calls a special meeting of stockholders for the purpose of
electing one or more directors to the Board of Directors, any such stockholder
may nominate a person or persons (as the case may be), for election to such
position(s) as specified in the corporation's notice of meeting, if the
stockholder's notice required by subparagraph (a)(ii) of this Section 13 shall
be 

                                       5

following the day on which public announcement is first made of the date of the
special meeting and of the nominees proposed by the Board of Directors to be

chairman of the meeting shall have the power and duty to determine whether a
nomination or any business proposed to be brought before the meeting was made or
proposed, as the case may be, in accordance with the procedures set forth in
this Section 1.12 and, if any proposed nomination or business is not in
compliance herewith, to declare that such defective proposal or nomination shall
be disregarded.

          (ii)  For purposes of this Section 13, the term "public announcement"
                                                           -------------------

Associated Press or comparable national news service or in a document publicly
filed by the corporation with the Securities and Exchange Commission pursuant to

          (iii) Notwithstanding the foregoing provisions of this Section 13, a
stockholder shall also comply with all applicable requirements of the Exchange
Act and the rules and regulations thereunder with respect to the matters set
forth herein.  Nothing in this Section 1.12 shall be deemed to affect any rights
of stockholders to request inclusion of proposals in the Corporation's proxy
statement pursuant to Rule 14a-8 under the Exchange Act.

     ----------  ------                                                        
managed by or under the direction of the Board of Directors, which may exercise
all such powers of the corporation and do all such lawful acts and things as are
not by law or these Bylaws directed or required to be exercised or done by the
stockholders.

less than five (5) members nor more than seven (7) members, the number thereof
to be fixed from time to time by resolution of the Board of Directors.  Any

     Section 3.  Election and Tenure. The directors shall be divided into three
     ----------  -------------------                                           
classes, with the term of office of the first class, which class initially
consists of two directors, to expire at the annual meeting of stockholders held
in 1998; the term of office of the second class, which class 

                                       6
<PAGE>
 
initially consists of two directors, to expire at the annual meeting of
stockholders held in 1999; the term of office of the third class, which class

     Section 4.  Qualification.  No Director need be a stockholder.
     ----------  -------------

Directors, may be removed from office at any time, with or without cause, but
only by the affirmative vote of the holders of at least a majority of the voting
power of all of the then outstanding shares of capital stock of the Corporation
entitled to vote generally in the election of directors, voting together as a
single class.  Vacancies in the Board of Directors resulting from such removal
may be filled by a majority of the directors then in office, though less than a
quorum, or by the stockholders as provided in Article II, Section 3 above.
Directors so chosen shall hold office until the next annual meeting of
stockholders.

     Section 6.  Resignation.  Any Director of the corporation may resign at any

time by giving written notice to the Board of Directors, to the Chairman of the
Board, if any, to the President, or to the Secretary, and any member of a
committee may resign therefrom at any time by giving notice as aforesaid or to
the chairman or secretary of such committee.  Any such resignation shall take
effect at the time specified therein, or, if the time be not specified, upon
receipt thereof; and unless otherwise specified therein, the acceptance of such
resignation shall not be necessary to make it effective.

     Section 7.  Vacancies and Newly Created Directorships.  Vacancies and newly
     ----------  -----------------------------------------                      
created directorships resulting from any increase in the authorized number of
Directors may be filled (a) by the stockholders at any meeting, (b) by a
majority of the Directors then in office, although less than a quorum, or (c) by
a sole remaining Director.  Whenever the holders of any class or classes of
stock or series thereof are entitled to elect one or more Directors by the
Certificate of Incorporation, vacancies and newly created directorships of such
class or classes or series may be filled by a majority of the Directors elected
by such class, classes or series then in office or by the sole remaining
director so elected.  When one or more Directors shall resign from the Board,
effective at a future date, a majority of Directors who are entitled to act on
the filling of such vacancy or vacancies and who are then in office, including
those who have so resigned, shall have power to fill such vacancy or vacancies
by vote to take effect when such resignation or resignations shall become
effective.

     Section 8.  Annual Meeting.  The first meeting of each newly elected board
     ----------  --------------                                                
may be held without notice immediately after an annual meeting of stockholders

ownership and merger pursuant to Section 253 of the Delaware General Corporation
Law.

face or back of each certificate issued by the corporation to represent such
class or series shall either (a) set forth in full or summarize the powers,
designations, preferences and relative, participating, optional or other special
rights of each class of stock or series thereof and the qualifications,
limitations or restrictions thereof, or

     (b)  contain a statement that the corporation will furnish a statement of
the same without charge to each stockholder who so requests.  Within a
reasonable time after the issuance or transfer of uncertificated shares, the
corporation shall send to the registered holder thereof such written notice as
may be required by law as to the information required by law to be set forth or
stated on stock certificates.

     Section 3.  Transfer of Stock.  Shares of stock shall be transferable
     ---------   -----------------

representing in the aggregate the number of shares involved shall be surrendered
for cancellation before a new certificate is issued representing such shares.

     Section 4.  Holders of Record.  Prior to due presentment for registration
     ---------   -----------------

stock as the complete owner thereof exclusively entitled to vote, to receive
notifications and otherwise entitled to all the rights and powers of a complete
owner thereof, notwithstanding notice to the contrary.

     Section 5.  Stock Certificates.  The Board of Directors may direct that a
     ---------   ------------------                                           
new stock certificate or certificates, or uncertificated shares, be issued in
place of any certificate or certificates theretofore issued by the corporation
alleged to have been lost, stolen, or destroyed upon the making of an affidavit
of that fact by the person claiming the certificate of stock to be lost, stolen
or destroyed.  When authorizing such issue of a new certificate or certificates,
or uncertificated shares, the Board of Directors may, in its discretion and as a
condition precedent to the issuance thereof, require the owner of such lost,
stolen or destroyed certificate or certificates or his or her legal
representative, to give the corporation a bond sufficient to indemnify it
against any claim that may be made against the corporation on account of the
alleged loss, theft, or destruction, of such certificates or the issuance of
such new certificate or certificates, or uncertificated shares.

     Section 6.  Record Date.  In order that the corporation may determine the
     ---------   -----------

to receive payment of any dividend or other distribution or allotment of any
rights or to exercise any rights in respect of any change, conversion or
exchange of stock or for the purpose of any other lawful action, the Board of
Directors may fix a record date, which record date shall not precede the 

                                      13
<PAGE>

date shall not be more than 60 nor less than 10 days before the date of any
meeting of stockholders, nor more than 60 days prior to the time for such other
action as hereinbefore described; provided, however, that if no record date is
fixed by the Board of Directors, the record date for determining stockholders
entitled to notice of or to vote at a meeting of stockholders shall be at the
close of business on the day next preceding the day on which notice is given or,
if notice is waived, at the close of business on the day next preceding the day
on which the meeting is held, and, for determining stockholders entitled to
receive payment of and dividend or other distribution or allotment of rights or
to exercise any rights of change, conversion or exchange of stock or for any
other purpose, the record date shall be at the close of business on the day on
which the Board of Directors adopts a resolution relating thereto. A
determination of stockholders of record entitled to notice of or to vote at a
meeting of stockholders shall apply to any adjournment of the meeting; provided,
however, that the Board of Directors may fix a new record date for the adjourned
meeting.

employee or agent or in any other capacity while serving as a director, officer,
to the fullest extent authorized by law, as the same exists or may hereafter be
amended (but, in the case of any such amendment, only to the extent that such
amendment permits the corporation to provide broader indemnification rights than
such law permitted the corporation to provide prior to such amendment), against
all expense, liability and loss (including attorneys' fees, judgments, fines,
ERISA excise taxes or penalties and amounts paid in settlement) reasonably
incurred or suffered by such indemnitee in connection therewith; provided,
however, that, except as provided in Subsection (c) of this Section with respect
to proceedings to enforce rights to indemnification, the corporation shall
indemnify any such indemnitee in connection with a proceeding (or part thereof)
initiated by such indemnitee only if such proceeding (or part thereof) was
authorized by the Board of Directors of the corporation; and provided further
that as to any matter disposed of by a compromise payment by such person,
pursuant to a consent decree or otherwise, no indemnification either for said
payment or for any other expenses shall be provided unless such compromise and
indemnification therefor shall be appropriated:

          (i)    by a majority vote of a quorum consisting of disinterested
     Directors;

          (ii)   if such a quorum cannot be obtained, then by a majority vote of
     a committee of the Board of Directors consisting of all the disinterested
     Directors;

          (iii)  if there are not two or more disinterested Directors in
     office, then by a majority of the Directors then in office, provided they
     have obtained a written finding by special independent legal counsel
     appointed by a majority of the Directors to the effect that, based upon a
     reasonable investigation of the relevant facts as described in such
     opinion, the person to be indemnified appears to have acted in good faith
     in the reasonable belief that his or her action was in the best interests
     of the corporation (or, to the extent that such matter relates to service
     with respect to an employee benefit plan, in the best interests of the
     participants or beneficiaries of such employee benefit plan);

          (iv)   by the holders of a majority of the shares of stock entitled to
     vote for the election of Directors, which majority may include interested
     Directors and officers; or

          (v)    by a court of competent jurisdiction.

                                      15

An "interested" Director or officer is one against whom in such capacity the
proceeding in question or other proceeding on the same or similar grounds is
then pending.  The termination of any action, suit or proceeding by judgment,
order, settlement, conviction, or upon a plea of nolo contendere or its
equivalent, shall not, of itself, create a presumption that the person did not
act in good faith and in a manner which he or she reasonably believed to be in
or not opposed to the best interests of the corporation, and, with respect to
any criminal action or proceeding, had reasonable cause to believe that his or
her conduct was unlawful.

     (b)  Right to Advancement of Expenses.  The right to indemnification
          --------------------------------                               
conferred in Subsection (a) of this Section shall include the right to be paid
by the corporation the expenses incurred in defending any such proceeding in
advance of its final disposition (hereinafter an "advancement of expenses");
provided, however, that, if the Delaware General Corporation Law requires, an
advancement of expenses incurred by an indemnitee in his or her capacity as a
director or officer (and not in any other capacity in which service was or is
rendered by such indemnitee, including, without limitation, service to an
employee benefit plan) shall be made only upon delivery to the corporation of an
undertaking (hereinafter an "undertaking"), by or on behalf of such indemnitee,
to repay all amounts so advanced if it shall ultimately be determined by final
judicial decision from which there is no further right to appeal (hereinafter a
"final adjudication") that such indemnitee is not entitled to be indemnified for
such expenses under this Section or otherwise, which undertaking may be accepted
without reference to the financial ability of such person to make repayment.

     (c)  Right of Indemnitee to Bring Suit.  If a claim under Subsection (a) or
          ---------------------------------                                     
(b) of this Section is not paid in full by the corporation within 60 days after
a written claim has been received by the corporation, except in the case of a
claim for an advancement of expenses, in which case the applicable period shall
be 20 days, the indemnitee may at any time there after bring suit against the
corporation to recover the unpaid amount of the claim.  If successful in whole
or in part of any such suit, or in a suit brought by the corporation to recover
an advancement of expenses pursuant to the terms of an undertaking, the
indemnitee shall be entitled to be paid also the expense of prosecuting or
defending such suit.  In (i) any suit brought by the indemnitee to enforce a
right to indemnification hereunder (but not in a suit brought by the indemnitee
to enforce a right to an advancement of expenses) it shall be a defense that,
and (ii) any suit by the corporation to recover an advancement of expenses
pursuant to the terms of an undertaking the corporation shall be entitled to
recover such expenses upon a final adjudication that, the indemnitee has not met
any applicable standard for indemnification set forth in the Delaware General
Corporation Law.  Neither the failure of the corporation (including its Board of
Directors, independent legal counsel, or its stockholders) to have made a
determination prior to the commencement of such suit that indemnification of the
indemnitee is proper in the circumstances because the indemnitee has met the
applicable standard of conduct set forth in the Delaware General Corporation
Law, nor an actual determination by the corporation (including its Board of
Directors, independent legal counsel, or its stockholders) that the indemnitee
has not met such applicable standard of conduct, shall create a presumption that
the indemnitee has not met the applicable standard of conduct or, in the case of
such a suit brought by the indemnitee, be a defense to such suit.  In any suit
brought by the indemnitee to enforce a right to indemnification or to an
advancement of expenses hereunder, or by the corporation to recover an
advancement of expenses pursuant to the terms of an undertaking, the burden of
proving that the indemnitee is 

                                      16
<PAGE>
 
not entitled to be indemnified, or to such advancement of expenses, under this
Section or otherwise shall be on the corporation.

     (d)  Non-exclusivity of Rights.  The rights to indemnification and to the
          -------------------------                                           
advancement of expenses conferred in this Section shall not be exclusive of any
other right which any person may have or hereafter acquire under any statute,
certificate of incorporation, by-law, agreement, vote of disinterested Directors
or otherwise.  The corporation's indemnification under this Section 2 of any
person who is or was a Director or officer of the corporation, or is or was
serving, at the request of the corporation, as a Director, officer, employee or
agent of another corporation, partnership, joint venture, trust or other
enterprise, shall be reduced by any amounts such person receives as
indemnification (i) under any policy of insurance purchased and maintained on
his or her behalf by the corporation, (ii) from such other corporation,
partnership, joint venture, trust or other enterprise, or (iii) under any other
applicable indemnification provision.

     (e)  Joint Representation.  If both the corporation and any person to be
          --------------------                                               
indemnified are parties to an action, suit or proceeding (other than an action
or suit by or in the right of the corporation to procure a judgment in its
favor), counsel representing the corporation therein may also represent such
indemnified person (unless such dual representation would involve such counsel
in a conflict of interest in violation of applicable principles of professional
ethics), and the corporation shall pay all fees and expenses of such counsel
incurred during the period of dual representation other than those, if any, as
would not have been incurred if counsel were representing only the corporation;
and any allocation made in good faith by such counsel of fees and disbursements
payable under this paragraph by the corporation versus fees and disbursements
payable by any such indemnified person shall be final and binding upon the
corporation and such indemnified person.

     (f)  Indemnification of Employees and Agents of the Corporation.  Except to
          ----------------------------------------------------------            
the extent that rights to indemnification and advancement of expenses of
employees or agents of the corporation may be required by any statute, the
Certificate of Incorporation, this Section or any other by-law, agreement, vote
of disinterested Directors or otherwise, the corporation may, to the extent
authorized from time to time by the Board of Directors, grant rights to
indemnification and to the advancement of to any employee or agent of the
corporation to the fullest extent of the provisions of this Section with respect
to the indemnification and advancement of expenses of Directors and officers of
the corporation.

     (g)  Insurance.  The corporation may maintain insurance, at its expense, to
          ---------                                                             
protect itself and any Director, officer, employee or agent of the corporation
or another corporation, partnership, joint venture, trust or other enterprise
against any expense, liability or loss, whether or not the corporation would
have the power to indemnify such person against such expense, liability or loss
under the Delaware General Corporation Law (as currently in effect or hereafter
amended), the corporation's Certificate of Incorporation or these Bylaws.

     (h)  Nature of Indemnification Right: Modification of Repeal of
          ----------------------------------------------------------
Indemnification.  Each person who is or becomes a Director or officer as
- ---------------                                                         
described in subsection (a) of this Section 2 shall be deemed to have served or
to have continued to serve in such capacity in reliance upon the indemnity
provided for in this Section 2.  All rights to indemnification (and the
advancement 

                                      17
<PAGE>
 
of expenses) under this Section 2 shall be deemed to be provided by a contract
between the corporation and the person who serves as a Director or officer of
the corporation at any time while these Bylaws and other relevant provisions of
the Delaware General Corporation Law and other applicable law, if any, are in
effect. Such rights shall continue as to an indemnitee who has ceased to be a
Director, officer, employee or agent and shall inure to the benefit of the
indemnitee's heirs, executors and administrators. Any modification or repeal of
this Section 2 shall not adversely affect any right or protection existing under
this Section 2 at the time of such modification or repeal.

     Section 3.  Stock in Other Corporations.  Subject to any limitations
     ---------   ---------------------------                             
that may be imposed by the Board of Directors, the President or any person or
persons authorized by the Board of Directors may, in the name and on behalf of
the corporation, (a) call meetings of the holders of stock or other securities
of any corporation or other organization, stock or other securities of which are
held by this corporation, (b) act, or appoint any other person or persons (with
or without powers of substitution) to act in the name and on behalf of the
corporation, or (c) express consent or dissent, as a holder of such securities,
to corporate or other action by such other corporation or organization.

     Section 4.  Checks, Notes, Drafts and Other Instruments.  Checks, notes,
     ---------   -------------------------------------------                 
drafts and other instruments for the payment of money drawn or endorsed in the
name of the corporation may be signed by any officer or officers or person or
persons authorized by the Board of Directors to sign the same.  No officer or
person shall sign any such instrument as aforesaid unless authorized by the
Board of Directors to do so.

     Section 5.  Corporate Seal.  The seal of the corporation shall be
     ---------   --------------                                       
circular in form, bearing the name of the corporation, the word "Delaware", and
the year of incorporation, and the same may be used by causing it or a facsimile
thereof to be impressed or affixed or in any other manner reproduced.

     Section 6.  Books and Records.  The books, accounts and records of the
     ---------   -----------------                                         
corporation, except as may be otherwise required by law, may be kept outside of
the State of Delaware, at such place or places as the Board of Directors may
from time to time appoint.  Except as may otherwise be provided by law, the
Board of Directors shall determine whether and to what extent the books,
accounts, records and documents of the corporation, or any of them, shall be
open to the inspection of the stockholders.

     Section 7.  Severability.  If any term or provision of the Bylaws, or the
     ---------   ------------                                                 
application thereof to any person or circumstances or period of time, shall to
any extent be invalid or unenforceable, the remainder of the Bylaws shall be
valid and enforced to the fullest extent permitted by law.

     Section 8.  Interpretations.  Words importing persons include firms,
     ---------   ---------------                                         
associations and corporations, all words importing the singular number include
the plural number and vice versa, and all words importing the masculine gender
include the feminine gender.

     Section 9.  Amendments.  The Board of Directors is expressly empowered to
     ---------   ----------                                                   
adopt, amend or repeal Bylaws of the corporation.  Any adoption, amendment or
repeal of Bylaws of 

                                      18
<PAGE>
 
the corporation by the Board of Directors shall require the approval of a
majority of the total number of authorized directors (whether or not there exist
any vacancies in previously authorized directorships at the time any resolution
providing for adoption, amendment or repeal is presented to the Board of
Directors). The stockholders also have power to adopt, amend or repeal the
Bylaws of the Corporation. Any adoption, amendment or repeal of Bylaws of the
corporation by the stockholders shall require, in addition to any vote of the
holders of any class or series of stock of the Corporation required by law or by
the Certificate of Incorporation, the affirmative vote of the holders of at
least a majority of the voting power of all of the then outstanding shares of
the capital stock of the corporation entitled to vote generally in the election
of directors, voting together as a single class.

                          As Adopted October 31, 1997



     1.  Purpose.  This 1998 Directors Stock Option Plan (this "Plan") is
established to provide equity incentives for certain nonemployee members of the
Board of Directors of VeriSign, Inc., (the "Company"), who are described in
Section 6.1 below, by granting such persons options to purchase shares of stock
of the Company.

     2.  Adoption and Stockholder Approval.  After this Plan is adopted by the
Board of Directors of the Company (the "Board"), this Plan will become effective
on the time and date (the "Effective Date") on which the registration statement
filed by the Company with the Securities and Exchange Commission ("SEC") under
the Securities Act of 1933, as amended (the "Securities Act"), to register the
initial public offering of the Company's Common Stock is declared effective by
the SEC.  This Plan shall be approved by the stockholders of the Company,
consistent with applicable laws, within twelve (12) months after the date this
Plan is adopted by the Board.

     3.  Types of Options and Shares.  Options granted under this Plan shall be
non-qualified stock options ("NQSOs").  The shares of stock that may be
purchased upon exercise of Options granted under this Plan (the "Shares") are
shares of the Common Stock of the Company.

     4.  Number of Shares.  The maximum number of Shares that may be issued
pursuant to Options granted under this Plan (the "Maximum Number") is 125,000
Shares, subject to adjustment as provided in this Plan.  If any Option is
terminated for any reason without being exercised in whole or in part, the
Shares thereby released from such Option shall be available for purchase under
other Options subsequently granted under this Plan.  At all times during the
term of this Plan, the Company shall reserve and keep available such number of
Shares as shall be required to satisfy the requirements of outstanding Options
granted under this Plan; provided, however that if the aggregate number of
Shares subject to outstanding Options granted under this Plan plus the aggregate
number of Shares previously issued by the Company pursuant to the exercise of
Options granted under this Plan equals or exceeds the Maximum Number, then
notwithstanding anything herein to the contrary, no further Options may be
granted under this Plan until the Maximum Number is increased or the aggregate
number of Shares subject to outstanding Options granted under this Plan plus the
aggregate number of Shares previously issued by the Company pursuant to the
exercise of Options granted under this Plan is less than the Maximum Number.

     5.  Administration.  This Plan shall be administered by the Board or by a
committee of not less than two members of the Board appointed to administer this
Plan (the "Committee").  As used in this Plan, references to the Committee shall
mean either such Committee or the Board if no Committee has been established.
The interpretation by the Committee of any of the provisions of this Plan or any
Option granted under this Plan shall be final and binding upon the Company and
all persons having an interest in any Option or any Shares purchased pursuant to
an Option.

     6.  Eligibility and Award Formula.

         6.1  Eligibility.  Options shall be granted only to directors of the
              -----------

such person referred to as an "Optionee").

         6.2  Initial Grant.  Each Optionee who on or after the Effective Date
              -------------
first becomes a member of the Board will automatically be granted an Option for
15,000 Shares (an "Initial Grant") on the date such Optionee becomes a member of
the Board.

              -----------------                                              
Initial Grant (or previous grant from the Company outside this Plan if such
Optionee was ineligible to receive an Initial Grant) provided the Optionee is a
member of the Board on such anniversary date and has served continuously as a
member of the Board since the date of such Optionee's Initial Grant or previous
grant, as the case may be, the Optionee will automatically be granted an Option
for 7,500 Shares (a "Succeeding Grant").

     7.  Terms and Conditions of Options.  Subject to the following and to
Section 6 above:

         7.1  Form of Option Grant.  Each Option granted under this Plan shall
              --------------------
be evidenced by a written Stock Option Grant ("Grant") in such form (which need
not be the same for each Optionee) as the Committee shall from time to time
approve, which Grant shall comply with and be subject to the terms and
conditions of this Plan.

         7.2  Vesting.  The date an Optionee receives an Initial Grant or a
              -------                                                      
Succeeding Grant is referred to in this Plan as the "Start Date" for such
Option.

              (a) Initial Grants.  Each Initial Grant will vest as to six and
                  --------------
one-fourth percent (6.25%) of the Shares on each three-month anniversary of the
Start Date for such Initial Grant, so long as the Optionee continuously remains
a director or, as determined by the Board in the Initial Grant or the Succeeding
Grant, a consultant of the Company.

              (b) Succeeding Grants.  Each Succeeding Grant will vest as to six
                  -----------------
and one-fourth percent (6.25%) of the Shares on each three-month anniversary of

remains a director or, as determined by the Board in the Initial Grant or the
Succeeding Grant, a consultant of the Company.

         7.3  Exercise Price.  The exercise price of an Option shall be the Fair
              --------------                                                    
Market Value (as defined in Section 18.4) of the Shares, at the time that the
Option is granted.

         7.4  Termination of Option.  Except as provided below in this Section,
              ---------------------
each Option shall expire ten (10) years after its Start Date (the "Expiration
Date"). The Option shall cease to vest when the Optionee ceases to be a member
of the Board or, as determined by the Board in the Initial Grant or the
Succeeding Grant, a consultant of the Company provided, however that if the
Optionee ceases to be a member of the Board or, as determined by the Board in
the Initial Grant or the Succeeding Grant, a consultant of the Company due to
death or total and permanent disability, the vesting of each Option shall
accelerate with respect to the number of shares that would have been vested on
the anniversary of the date of grant next following the Optionee's termination
date. The date on which the Optionee ceases to be a member of the Board or, as
determined by the Board in the Initial Grant or the Succeeding Grant, a
consultant of the Company shall be referred to as the "Termination Date". An
Option may be exercised after the Termination Date only as set forth below:

              (a) Termination Generally.  If the Optionee ceases to be a member
                  ---------------------
of the Board or, as determined by the Board in the Initial Grant or the
Succeeding Grant, a consultant of the Company for any reason except death of the
Optionee or disability of the Optionee (whether temporary or permanent, partial
or total, as determined by the Committee), then each Option then held by such
Optionee, to the extent (and only to the extent) that it would have been
exercisable by the Optionee on the Termination Date, may be exercised by the
Optionee no later than seven (7) months after the Termination Date, but in no
event later than the Expiration Date.

              (b) Death or Disability.  If the Optionee ceases to be a member of
                  -------------------
the Board or, as determined by the Board in the Initial Grant or the Succeeding
Grant, a consultant of the Company because of the death of the Optionee or the
disability of the Optionee (whether temporary or permanent, partial or total, as
determined by the Committee), then each Option then held by such Optionee to the
extent (and only to the extent) that it would have been exercisable by the
Optionee on the Termination Date, may be exercised by the Optionee (or 

                                      -2-
<PAGE>
 
the Optionee's legal representative) no later than twelve (12) months after the
Termination Date, but in no event later than the Expiration Date.

     8.  Exercise of Options.


         8.1  Exercise Period.  Subject to the provisions of Section 8.5 below,
              ---------------                                                  
Options shall be exercisable as they vest.

         8.2  Notice.  Options may be exercised only by delivery to the Company
              ------
of an exercise agreement in a form approved by the Committee stating the number
of Shares being purchased, the restrictions imposed on the Shares and such
representations and agreements regarding the Optionee's investment intent and
access to information as may be required by the Company to comply with
applicable securities laws, together with payment in full of the exercise price
for the number of Shares being purchased.

         8.3  Payment.  Payment for the Shares purchased upon exercise of an
              -------
Option may be made (a) in cash or by check; (b) by surrender of shares of Common
Stock of the Company that have been owned by the Optionee for more than six (6)
months (and which have been paid for within the meaning of SEC Rule 144 and, if
such shares were purchased from the Company by use of a promissory note, such
note has been fully paid with respect to such shares) or were obtained by the
Optionee in the open public market, having a Fair Market Value equal to the
exercise price of the Option; (c) by waiver of compensation due or accrued to
the Optionee for services rendered; (d) provided that a public market for the
Company's stock exists, through a "same day sale" commitment from the Optionee
and a broker-dealer that is a member of the National Association of Securities
Dealers (an "NASD Dealer") whereby the Optionee irrevocably elects to exercise
the Option and to sell a portion of the Shares so purchased to pay for the
exercise price and whereby the NASD Dealer irrevocably commits upon receipt of
such Shares to forward the exercise price directly to the Company; (e) provided
that a public market for the Company's stock exists, through a "margin"
commitment from the Optionee and an NASD Dealer whereby the Optionee irrevocably
elects to exercise the Option and to pledge the Shares so purchased to the NASD
Dealer in a margin account as security for a loan from the NASD Dealer in the
amount of the exercise price, and whereby the NASD Dealer irrevocably commits
upon receipt of such Shares to forward the exercise price directly to the
Company; or (f) by any combination of the foregoing.

         8.4  Withholding Taxes.  Prior to issuance of the Shares upon exercise
              -----------------
of an Option, the Optionee shall pay or make adequate provision for any federal
or state withholding obligations of the Company, if applicable.

         8.5  Limitations on Exercise.  Notwithstanding the exercise periods set
              -----------------------                                           
forth in the Grant, exercise of an Option shall always be subject to the
following limitations:

              (a) An Option shall not be exercisable unless such exercise is in
compliance with the Securities Act and all applicable state securities laws, as
they are in effect on the date of exercise.

              (b) The Committee may specify a reasonable minimum number of
Shares that may be purchased upon any exercise of an Option, provided that such
minimum number will not prevent the Optionee from exercising the full number of
Shares as to which the Option is then exercisable.

     9.  Nontransferability of Options.  During the lifetime of the Optionee, an
Option shall be exercisable only by the Optionee or by the Optionee's guardian
or legal representative, unless otherwise determined by the Committee.  No
Option may be sold, pledged, assigned, hypothecated, transferred or disposed of
in any manner other than by will or by the laws of descent and distribution,
unless otherwise determined by the Committee.

     10. Privileges of Stock Ownership.  No Optionee shall have any of the
rights of a stockholder with respect to any Shares subject to an Option until
the Option has been validly exercised.  No adjustment shall be made for
dividends or distributions or other rights for which the record date is prior to
the date of exercise, except as 

                                      -3-
<PAGE>
 
provided in this Plan. The Company shall provide to each Optionee a copy of the
annual financial statements of the Company at such time after the close of each
fiscal year of the Company as they are released by the Company to its
stockholders.

     11. Adjustment of Option Shares.  In the event that the number of
outstanding shares of Common Stock of the Company is changed by a stock
dividend, stock split, reverse stock split, combination, reclassification or
similar change in the capital structure of the Company without consideration,
the number of Shares available under this Plan and the number of Shares subject
to outstanding Options and the exercise price per share of such outstanding
Options shall be proportionately adjusted, subject to any required action by the
Board or stockholders of the Company and compliance with applicable securities
laws; provided, however, that no fractional shares shall be issued upon exercise
of any Option and any resulting fractions of a Share shall be rounded up to the
nearest whole Share.

     12. No Obligation to Continue as Director.  Nothing in this Plan or any
Option granted under this Plan shall confer on any Optionee any right to
continue as a director of the Company.

     13. Compliance With Laws.  The grant of Options and the issuance of Shares
upon exercise of any Options shall be subject to and conditioned upon compliance
with all applicable requirements of law, including without limitation compliance
with the Securities Act, compliance with all other applicable state securities
laws and compliance with the requirements of any stock exchange or national
market system on which the Shares may be listed.  The Company shall be under no
obligation to register the Shares with the SEC or to effect compliance with the
registration or qualification requirement of any state securities laws, stock
exchange or national market system.

     14. Acceleration of Options on Certain Corporate Transactions.  In the
event of (a) a dissolution or liquidation of the Company, (b) a merger or
consolidation in which the Company is not the surviving corporation (other than
a merger or consolidation with a wholly-owned subsidiary, a reincorporation of
the Company in a different jurisdiction, or other transaction in which there is
no substantial change in the stockholders of the Company or their relative stock
holdings and the Options granted under this Plan are assumed, converted or
replaced by the successor corporation, which assumption, conversion or
replacement will be binding on all Optionees), (c) a merger in which the Company
is the surviving corporation but after which the stockholders of the Company
(other than any stockholder which merges (or which owns or controls another
corporation which merges) with the Company in such merger) cease to own their
shares or other equity interests in the Company, (d) the sale of substantially
all of the assets of the Company, or (e) the acquisition, sale or transfer of
more than 50% of the outstanding shares of the Company by tender offer or
similar transaction, the vesting of all options granted pursuant to this Plan
will accelerate and the options will become exercisable in full prior to the
consummation of such event at such times and on such conditions as the Committee
determines, and must be exercised, if at all, within six months of the
consummation of said event.  Any options not exercised within such six-month
period shall expire.

     15. Amendment or Termination of Plan.  The Board may at any time terminate
or amend this Plan or any outstanding option, provided that the Board may not
terminate or amend the terms of any outstanding option without the consent of
the Optionee.  In any case, no amendment of this Plan may adversely affect any
then outstanding Options or any unexercised portions thereof without the written
consent of the Optionee.

     16. Term of Plan.  Options may be granted pursuant to this Plan from time
to time within a period of ten (10) years from the Effective Date.

     17. Certain Definitions.  As used in this Plan, the following terms shall
have the following meanings:

         17.1 "Parent" means any corporation (other than the Company) in an
unbroken chain of corporations ending with the Company if each of such
corporations other than the Company owns stock possessing 50% or more of the

                                                                   -------------
                                        
                                VERISIGN, INC.

                           1998 EQUITY INCENTIVE PLAN

                          As Adopted October 31, 1997



          1.   PURPOSE.  The purpose of this Plan is to provide incentives to
               -------                                                       
attract, retain and motivate eligible persons whose present and potential
contributions are important to the success of the Company, its Parent and
Subsidiaries, by offering them an opportunity to participate in the Company's
future performance through awards of Options, Restricted Stock and Stock
Bonuses.  Capitalized terms not defined in the text are defined in Section 23.

          2.   SHARES SUBJECT TO THE PLAN.
               -------------------------- 

               2.1  Number of Shares Available.  Subject to Sections 2.2 and 18,
                    --------------------------                                  
the total number of Shares reserved and available for grant and issuance
pursuant to this Plan will be 2,000,000 Shares.  Subject to Sections 2.2 and 18,
Shares that: (a) are subject to issuance upon exercise of an Option but cease to
be subject to such Option for any reason other than exercise of such Option; (b)
are subject to an Award granted hereunder but are forfeited or are repurchased
by the Company at the original issue price; or (c) are subject to an Award that
otherwise terminates without Shares being issued, will again be available for
grant and issuance in connection with future Awards under this Plan.  Any
authorized shares not issued or subject to outstanding grants under the
Company's 1997 Stock Option Plan and the Company's 1995 Stock Option Plan (the
"Prior Plans") on the Effective Date (as defined below) and any shares that are
issuable upon exercise of options granted pursuant to the Prior Plans that
expire or become unexercisable for any reason without having been exercised in
full, will no longer be available for grant and issuance under the Prior Plans,
but will be available for grant and issuance under this Plan.  In addition, any
shares issued under the Prior Plans which are repurchased or forfeited will be
available for grant and issuance under this Plan.  At all times the Company
shall reserve and keep available a sufficient number of Shares as shall be
required to satisfy the requirements of all outstanding Options granted under
this Plan and all other outstanding but unvested Awards granted under this Plan.

               2.2  Adjustment of Shares.  In the event that the number of
                    --------------------                                  
outstanding shares is changed by a stock dividend, recapitalization, stock
split, reverse stock split, subdivision, combination, reclassification or
similar change in the capital structure of the Company without consideration,
then (a) the number of Shares reserved for issuance under this Plan, (b) the
Exercise Prices of and number of Shares subject to outstanding Options, and (c)
the number of Shares subject to other outstanding Awards will be proportionately
adjusted, subject to any required action by the Board or the stockholders of the
Company and compliance with applicable securities laws; provided, however, that
                                                        --------  -------      
fractions of a Share will not be issued but will either be replaced by a cash
payment equal to the Fair Market Value of such fraction of a Share or will be
rounded up to the nearest whole Share, as determined by the Committee.


          3.   ELIGIBILITY.  ISOs (as defined in Section 5 below) may be granted
               -----------                                                      
only to employees (including officers and directors who are also employees) of
the Company or of a Parent or Subsidiary of the Company.  All other Awards may
be granted to employees, officers, directors, consultants, independent
contractors and advisors of the Company or any Parent or Subsidiary of the
Company; provided such consultants, contractors and advisors render bona fide
         --------                                                            
services not in connection with the offer and sale of securities in a capital-
raising transaction.  No person will be eligible to receive more than 400,000
Shares in any calendar year under this Plan pursuant to the grant of Awards
hereunder, other than new employees of the Company or of a Parent or Subsidiary
of the Company (including new employees who are also officers and directors of
the Company or any Parent or Subsidiary of the Company), who are eligible to
receive up to a maximum of 1,000,000 Shares in the calendar year in which they
commence their employment.  A person may be granted more than one Award under
this Plan.

          4.   ADMINISTRATION.
               -------------- 

               4.1  Committee Authority.  This Plan will be administered by the
                    -------------------

purposes, terms and conditions of this Plan, and to the direction of the Board,
the Committee will have full power to implement and carry out this Plan.
Without limitation, the Committee will have the authority to:

          (e)  determine the number of Shares or other consideration subject to

          (f)  determine whether Awards will be granted singly, in combination
               with, in tandem with, in replacement of, or as alternatives to,
               other Awards under this Plan or any other incentive or
               compensation plan of the Company or any Parent or Subsidiary of
               the Company;

          (g)  grant waivers of Plan or Award conditions;

          (j)  determine whether an Award has been earned; and

          (k)  make all other determinations necessary or advisable for the
               administration of this Plan.

               4.2  Committee Discretion.  Any determination made by the
                    --------------------                                
Committee with respect to any Award will be made in its sole discretion at the
time of grant of the Award or, unless in contravention of any express term of
this Plan or Award, at any later time, and such determination will be final and
binding on the Company and on all persons having an interest in any Award under
this Plan.  The Committee may delegate to one or more officers of the Company
the authority to grant an Award under this Plan to Participants who are not
Insiders of the Company.

          5.   OPTIONS.  The Committee may grant Options to eligible persons and
               -------                                                          
will determine whether such Options will be Incentive Stock Options within the
meaning of the Code ("ISO") or Nonqualified Stock Options ("NQSOs"), the number
of Shares subject to the Option, the Exercise Price of the Option, the period
during which the Option may be exercised, and all other terms and conditions of
the Option, subject to the following:

               5.1  Form of Option Grant.  Each Option granted under this Plan
                    --------------------                                      
will be evidenced by an Award Agreement which will expressly identify the Option
as an ISO or an NQSO ("Stock Option Agreement"), and will be in such form and
contain such provisions (which need not be the same for each Participant) as the
Committee may from time to time approve, and which will comply with and be
subject to the terms and conditions of this Plan.

                                                      1998 Equity Incentive Plan


          5.2  Date of Grant.  The date of grant of an Option will be the date
               -------------                                             
on which the Committee makes the determination to grant such Option, unless
otherwise specified by the Committee. The Stock Option Agreement and a copy of
this Plan will be delivered to the Participant within a reasonable time after
the granting of the Option.

          5.3  Exercise Period.  Options may be exercisable within the times or
               ---------------                                              
upon the events determined by the Committee as set forth in the Stock Option
Agreement governing such Option; provided, however, that no Option will be
                                 --------  -------                        
exercisable after the expiration of ten (10) years from the date the Option is
granted; and provided further that no ISO granted to a person who directly or by
             ----------------                                                   
attribution owns more than ten percent (10%) of the total combined voting power
of all classes of stock of the Company or of any Parent or Subsidiary of the
Company ("Ten Percent Stockholder") will be exercisable after the expiration of
five (5) years from the date the ISO is granted.  The Committee also may provide
for Options to become exercisable at one time or from time to time, periodically
or otherwise, in such number of Shares or percentage of Shares as the Committee
determines.

          5.4  Exercise Price.  The Exercise Price of an Option will be
               --------------                                          
determined by the Committee when the Option is granted and may be not less than
85% of the Fair Market Value of the Shares on the date of grant; provided that:
(i) the Exercise Price of an ISO will be not less than 100% of the Fair Market
Value of the Shares on the date of grant; and (ii) the Exercise Price of any ISO
granted to a Ten Percent Stockholder will not be less than 110% of the Fair
Market Value of the Shares on the date of grant. Payment for the Shares
purchased may be made in accordance with Section 8 of this Plan.

          5.5  Method of Exercise.  Options may be exercised only by delivery to
               ------------------                                   
the Company of a written stock option exercise agreement (the "Exercise
Agreement") in a form approved by the Committee (which need not be the same for
each Participant), stating the number of Shares being purchased, the
restrictions imposed on the Shares purchased under such Exercise Agreement, if
any, and such representations and agreements regarding Participant's investment
intent and access to information and other matters, if any, as may be required
or desirable by the Company to comply with applicable securities laws, together
with payment in full of the Exercise Price for the number of Shares being
purchased.

          5.6  Termination.  Notwithstanding the exercise periods set forth in
               -----------                                                 
the Stock Option Agreement, exercise of an Option will always be subject to the
following:

          (a)  If the Participant is Terminated for any reason except death or
               Disability, then the Participant may exercise such Participant's
               Options only to the extent that such Options would have been
               exercisable upon the Termination Date no later than three (3)
               months after the Termination Date (or such shorter or longer time
               period not exceeding five (5) years as may be determined by the
               Committee, with any exercise beyond three (3) months after the
               Termination Date deemed to be an NQSO), but in any event, no
               later than the expiration date of the Options.

          (b)  If the Participant is Terminated because of Participant's death
               or Disability (or the Participant dies within three (3) months
               after a Termination other than because of Participant's death or
               disability), then Participant's Options may be exercised only to
               the extent that such Options would have been exercisable by
               Participant on the Termination Date and must be exercised by
               Participant (or Participant's legal representative or authorized
               assignee) no later than twelve (12) months after the Termination
               Date (or such shorter or longer time period not exceeding five
               (5) years as may be determined by the Committee, with any such
               exercise beyond (a) three (3) months after the Termination Date
               when the Termination is for any reason other than the
               Participant's death or Disability, or (b) twelve (12) months
               after the Termination Date when the Termination is for
               Participant's death or Disability, deemed to be an NQSO), but in
               any event no later than the expiration date of the Options.

                                                                  VeriSign, Inc.
                                                      1998 Equity Incentive Plan


          (c)  Notwithstanding the provisions in paragraph 5.6(a) above, if a
               Participant is terminated for Cause, neither the Participant, the
               Participant's estate nor such other person who may then hold the
               Option shall be entitled to exercise any Option with respect to
               any Shares whatsoever, after termination of service, whether or
               not after termination of service the Participant may receive
               payment from the Company or Subsidiary for vacation pay, for
               services rendered prior to termination, for services rendered for
               the day on which termination occurs, for salary in lieu of
               notice, or for any other benefits. In making such determination,
               the Board shall give the Participant an opportunity to present to
               the Board evidence on his behalf. For the purpose of this
               paragraph, termination of service shall be deemed to occur on the
               date when the Company dispatches notice or advice to the
               Participant that his service is terminated.

          5.7  Limitations on Exercise.  The Committee may specify a reasonable
               -----------------------                              
minimum number of Shares that may be purchased on any exercise of an Option,
provided that such minimum number will not prevent Participant from exercising
the Option for the full number of Shares for which it is then exercisable.

          5.8  Limitations on ISO.  The aggregate Fair Market Value (determined
               ------------------                                  
as of the date of grant) of Shares with respect to which ISO are exercisable for
the first time by a Participant during any calendar year (under this Plan or
under any other incentive stock option plan of the Company, Parent or Subsidiary
of the Company) will not exceed $100,000. If the Fair Market Value of Shares on
the date of grant with respect to which ISO are exercisable for the first time
by a Participant during any calendar year exceeds $100,000, then the Options for
the first $100,000 worth of Shares to become exercisable in such calendar year
will be ISO and the Options for the amount in excess of $100,000 that become
exercisable in that calendar year will be NQSOs. In the event that the Code or
the regulations promulgated thereunder are amended after the Effective Date of
this Plan to provide for a different limit on the Fair Market Value of Shares
permitted to be subject to ISO, such different limit will be automatically
incorporated herein and will apply to any Options granted after the effective
date of such amendment.

          5.9  Modification, Extension or Renewal.  The Committee may modify,
               ----------------------------------                    
extend or renew outstanding Options and authorize the grant of new Options in
substitution therefor, provided that any such action may not, without the
written consent of a Participant, impair any of such Participant's rights under
any Option previously granted. Any outstanding ISO that is modified, extended,
renewed or otherwise altered will be treated in accordance with Section 424(h)
of the Code. The Committee may reduce the Exercise Price of outstanding Options
without the consent of Participants affected by a written notice to them;
provided, however, that the Exercise Price may not be reduced below the minimum
- --------  -------                                            
Exercise Price that would be permitted under Section 5.4 of this Plan for
Options granted on the date the action is taken to reduce the Exercise Price.

          5.10 No Disqualification.  Notwithstanding any other provision in this
               -------------------                                         
Plan, no term of this Plan relating to ISO will be interpreted, amended or
altered, nor will any discretion or authority granted under this Plan be
exercised, so as to disqualify this Plan under Section 422 of the Code or,
without the consent of the Participant affected, to disqualify any ISO under
Section 422 of the Code.

          6.   RESTRICTED STOCK.  A Restricted Stock Award is an offer by the
               ----------------                                              
Company to sell to an eligible person Shares that are subject to restrictions.
The Committee will determine to whom an offer will be made, the number of Shares
the person may purchase, the price to be paid (the "Purchase Price"), the
restrictions to which the Shares will be subject, and all other terms and
conditions of the Restricted Stock Award, subject to the following:

               6.1  Form of Restricted Stock Award.  All purchases under a
                    ------------------------------                        
Restricted Stock Award made pursuant to this Plan will be evidenced by an Award
Agreement ("Restricted Stock Purchase Agreement") that will be in such form
(which need not be the same for each Participant) as the Committee will from
time to time approve, and will comply with and be subject to the terms and
conditions of this Plan.  The offer of Restricted Stock will be accepted by the
Participant's execution and delivery of the Restricted Stock Purchase Agreement
and full payment for the Shares to the Company within thirty (30) days from the
date the Restricted Stock Purchase Agree-

ment is delivered to the person. If such person does not execute and deliver the
Restricted Stock Purchase Agreement along with full payment for the Shares to
the Company within thirty (30) days, then the offer will terminate, unless
otherwise determined by the Committee.

          6.2  Purchase Price.  The Purchase Price of Shares sold pursuant to a
               --------------                                             
Restricted Stock Award will be determined by the Committee on the date the
Restricted Stock Award is granted, except in the case of a sale to a Ten Percent
Stockholder, in which case the Purchase Price will be 100% of the Fair Market
Value. Payment of the Purchase Price may be made in accordance with Section 8 of
this Plan.

          6.3  Terms of Restricted Stock Awards.  Restricted Stock Awards shall
               --------------------------------                          
be subject to such restrictions as the Committee may impose. These restrictions
may be based upon completion of a specified number of years of service with the
Company or upon completion of the performance goals as set out in advance in the
Participant's individual Restricted Stock Purchase Agreement. Restricted Stock
Awards may vary from Participant to Participant and between groups of
Participants. Prior to the grant of a Restricted Stock Award, the Committee
shall: (a) determine the nature, length and starting date of any Performance
Period for the Restricted Stock Award; (b) select from among the Performance
Factors to be used to measure performance goals, if any; and (c) determine the
number of Shares that may be awarded to the Participant. Prior to the payment of
any Restricted Stock Award, the Committee shall determine the extent to which
such Restricted Stock Award has been earned. Performance Periods may overlap and
Participants may participate simultaneously with respect to Restricted Stock
Awards that are subject to different Performance Periods and having different
performance goals and other criteria.

          6.4  Termination During Performance Period.  If a Participant is
               -------------------------------------                      
Terminated during a Performance Period for any reason, then such Participant
will be entitled to payment (whether in Shares, cash or otherwise) with respect
to the Restricted Stock Award only to the extent earned as of the date of
Termination in accordance with the Restricted Stock Purchase Agreement, unless
the Committee will determine otherwise.

          7.   STOCK BONUSES.
               ------------- 

               7.1  Awards of Stock Bonuses.  A Stock Bonus is an award of

Shares (which may consist of Restricted Stock) for services rendered to the
Company or any Parent or Subsidiary of the Company. A Stock Bonus may be awarded
for past services already rendered to the Company, or any Parent or Subsidiary
of the Company pursuant to an Award Agreement (the "Stock Bonus Agreement") that
will be in such form (which need not be the same for each Participant) as the
Committee will from time to time approve, and will comply with and be subject to
the terms and conditions of this Plan. A Stock Bonus may be awarded upon
satisfaction of such performance goals as are set out in advance in the
Participant's individual Award Agreement (the "Performance Stock Bonus
Agreement") that will be in such form (which need not be the same for each
Participant) as the Committee will from time to time approve, and will comply
with and be subject to the terms and conditions of this Plan. Stock Bonuses may
vary from Participant to Participant and between groups of Participants, and may
be based upon the achievement of the Company, Parent or Subsidiary and/or
individual performance factors or upon such other criteria as the Committee may
determine.

          7.2  Terms of Stock Bonuses.  The Committee will determine the number
               ----------------------                                   
of Shares to be awarded to the Participant. If the Stock Bonus is being earned
upon the satisfaction of performance goals pursuant to a Performance Stock Bonus
Agreement, then the Committee will: (a) determine the nature, length and
starting date of any Performance Period for each Stock Bonus; (b) select from
among the Performance Factors to be used to measure the performance, if any; and
(c) determine the number of Shares that may be awarded to the Participant. Prior
to the payment of any Stock Bonus, the Committee shall determine the extent to
which such Stock Bonuses have been earned. Performance Periods may overlap and
Participants may participate simultaneously with respect to Stock Bonuses that
are subject to different Performance Periods and different performance goals and
other criteria. The number of Shares may be fixed or may vary in accordance with
such performance goals and criteria as may be determined by the Committee. The
Committee may adjust the performance goals applicable to the Stock Bonuses to
take into account changes in law and accounting or tax rules and to make such
adjustments as

the Committee deems necessary or appropriate to reflect the impact of
extraordinary or unusual items, events or circumstances to avoid windfalls or
hardships.

          7.3  Form of Payment.  The earned portion of a Stock Bonus may be paid
               ---------------                                             
currently or on a deferred basis with such interest or dividend equivalent, if
any, as the Committee may determine. Payment may be made in the form of cash or
whole Shares or a combination thereof, either in a lump sum payment or in
installments, all as the Committee will determine.

          8.   PAYMENT FOR SHARE PURCHASES.
               --------------------------- 

               8.1  Payment.  Payment for Shares purchased pursuant to this Plan
                    -------                                                     
may be made in cash (by check) or, where expressly approved for the Participant
by the Committee and where permitted by law:

          (a)  by cancellation of indebtedness of the Company to the
               Participant;

          (b)  by surrender of shares that either:  (1) have been owned by
               Participant for more than six (6) months and have been paid for
               within the meaning of SEC Rule 144 (and, if such shares were
               purchased from the Company by use of a promissory note, such note
               has been fully paid with respect to such shares); or (2) were
               obtained by Participant in the public market;

          (c)  by tender of a full recourse promissory note having such terms as
               may be approved by the Committee and bearing interest at a rate
               sufficient to avoid imputation of income under Sections 483 and
               1274 of the Code; provided, however, that Participants who are
                                 --------  -------
               not employees or directors of the Company will not be entitled to
               purchase Shares with a promissory note unless the note is
               adequately secured by collateral other than the Shares;

          (d)  by waiver of compensation due or accrued to the Participant for
               services rendered;

          (e)  with respect only to purchases upon exercise of an Option, and
               provided that a public market for the Company's stock exists:

               (1)  through a "same day sale" commitment from the Participant
                    and a broker-dealer that is a member of the National
                    Association of Securities Dealers (an "NASD Dealer") whereby
                    the Participant irrevocably elects to exercise the Option
                    and to sell a portion of the Shares so purchased to pay for
                    the Exercise Price, and whereby the NASD Dealer irrevocably
                    commits upon receipt of such Shares to forward the Exercise
                    Price directly to the Company; or

               (2)  through a "margin" commitment from the Participant and a
                    NASD Dealer whereby the Participant irrevocably elects to
                    exercise the Option and to pledge the Shares so purchased to
                    the NASD Dealer in a margin account as security for a loan
                    from the NASD Dealer in the amount of the Exercise Price,
                    and whereby the NASD Dealer irrevocably commits upon receipt
                    of such Shares to forward the Exercise Price directly to the
                    Company; or

          (f)  by any combination of the foregoing.


               8.2  Loan Guarantees.  The Committee may help the Participant pay
                    ---------------                                             
for Shares purchased under this Plan by authorizing a guarantee by the Company
of a third-party loan to the Participant.

          9.   WITHHOLDING TAXES.
               ----------------- 

               9.1  Withholding Generally.  Whenever Shares are to be issued in
                    ---------------------                                      
satisfaction of Awards granted under this Plan, the Company may require the
Participant to remit to the Company an amount sufficient to satisfy federal,
state and local withholding tax requirements prior to the delivery of any
certificate or certificates for such Shares.  Whenever, under this Plan,
payments in satisfaction of Awards are to be made in cash, such payment will be
net of an amount sufficient to satisfy federal, state, and local withholding tax
requirements.

               9.2  Stock Withholding.  When, under applicable tax laws, a
                    -----------------                                     
Participant incurs tax liability in connection with the exercise or vesting of
any Award that is subject to tax withholding and the Participant is obligated to
pay the Company the amount required to be withheld, the Committee may in its
sole discretion allow the Participant to satisfy the minimum withholding tax
obligation by electing to have the Company withhold from the Shares to be issued
that number of Shares having a Fair Market Value equal to the minimum amount
required to be withheld, determined on the date that the amount of tax to be
withheld is to be determined.  All elections by a Participant to have Shares
withheld for this purpose will be made in accordance with the requirements
established by the Committee and be in writing in a form acceptable to the
Committee.

          10.  PRIVILEGES OF STOCK OWNERSHIP.
               ----------------------------- 

               10.1 Voting and Dividends.  No Participant will have any of the
                    --------------------                                      
rights of a stockholder with respect to any Shares until the Shares are issued
to the Participant.  After Shares are issued to the Participant, the Participant
will be a stockholder and have all the rights of a stockholder with respect to
such Shares, including the right to vote and receive all dividends or other
distributions made or paid with respect to such Shares; provided, that if such
                                                        --------              
Shares are Restricted Stock, then any new, additional or different securities
the Participant may become entitled to receive with respect to such Shares by
virtue of a stock dividend, stock split or any other change in the corporate or
capital structure of the Company will be subject to the same restrictions as the
Restricted Stock; provided, further, that the Participant will have no right to
                  --------  -------                                            
retain such stock dividends or stock distributions with respect to Shares that
are repurchased at the Participant's Purchase Price or Exercise Price pursuant
to Section 12.

               10.2 Financial Statements.  The Company will provide financial
                    --------------------                                     
statements to each Participant prior to such Participant's purchase of Shares
under this Plan, and to each Participant annually during the period such
Participant has Awards outstanding; provided, however, the Company will not be
                                    --------  -------                         
required to provide such financial statements to Participants whose services in
connection with the Company assure them access to equivalent information.

          11.  TRANSFERABILITY.  Awards granted under this Plan, and any
               ---------------
interest therein, will not be transferable or assignable by Participant, and may
not be made subject to execution, attachment or similar process, otherwise than
by will or by the laws of descent and distribution or as determined by the
Committee and set forth in the Award Agreement with respect to Awards that are
not ISOs. During the lifetime of the Participant an Award will be exercisable
only by the Participant, and any elections with respect to an Award may be made
only by the Participant unless otherwise determined by the Committee and set
forth in the Award Agreement with respect to Awards that are not ISOs.

          12.  RESTRICTIONS ON SHARES.  At the discretion of the Committee, the
               ----------------------                                          
Company may reserve to itself and/or its assignee(s) in the Award Agreement a
right to repurchase a portion of or all Unvested Shares held by a Participant
following such Participant's Termination at any time within ninety (90) days
after the later of Participant's Termination Date and the date Participant
purchases Shares under this Plan, for cash and/or cancellation of purchase money
indebtedness, at the Participant's Exercise Price or Purchase Price, as the case
may be.

          13.  CERTIFICATES.  All certificates for Shares or other securities
               ------------                                                  
delivered under this Plan will be subject to such stock transfer orders, legends
and other restrictions as the Committee may deem necessary or

                                                                  VeriSign, Inc.
                                                      1998 Equity Incentive Plan


advisable, including restrictions under any applicable federal, state or foreign
securities law, or any rules, regulations and other requirements of the SEC or
any stock exchange or automated quotation system upon which the Shares may be
listed or quoted.

          14.  ESCROW; PLEDGE OF SHARES.  To enforce any restrictions on a
               ------------------------                                   
Participant's Shares, the Committee may require the Participant to deposit all
certificates representing Shares, together with stock powers or other
instruments of transfer approved by the Committee, appropriately endorsed in
blank, with the Company or an agent designated by the Company to hold in escrow
until such restrictions have lapsed or terminated, and the Committee may cause a
legend or legends referencing such restrictions to be placed on the
certificates.  Any Participant who is permitted to execute a promissory note as
partial or full consideration for the purchase of Shares under this Plan will be
required to pledge and deposit with the Company all or part of the Shares so
purchased as collateral to secure the payment of Participant's obligation to the
Company under the promissory note; provided, however, that the Committee may
                                   --------  -------                        
require or accept other or additional forms of collateral to secure the payment
of such obligation and, in any event, the Company will have full recourse
against the Participant under the promissory note notwithstanding any pledge of
the Participant's Shares or other collateral.  In connection with any pledge of
the Shares, Participant will be required to execute and deliver a written pledge
agreement in such form as the Committee will from time to time approve.  The
Shares purchased with the promissory note may be released from the pledge on a
pro rata basis as the promissory note is paid.

          15.  EXCHANGE AND BUYOUT OF AWARDS.  The Committee may, at any time or
               -----------------------------                                    
from time to time, authorize the Company, with the consent of the respective
Participants, to issue new Awards in exchange for the surrender and cancellation
of any or all outstanding Awards.  The Committee may at any time buy from a
Participant an Award previously granted with payment in cash, Shares (including
Restricted Stock) or other consideration, based on such terms and conditions as
the Committee and the Participant may agree.

          16.  SECURITIES LAW AND OTHER REGULATORY COMPLIANCE.  An Award will
               ----------------------------------------------      
not be effective unless such Award is in compliance with all applicable federal
and state securities laws, rules and regulations of any governmental body, and
the requirements of any stock exchange or automated quotation system upon which
the Shares may then be listed or quoted, as they are in effect on the date of
grant of the Award and also on the date of exercise or other issuance.
Notwithstanding any other provision in this Plan, the Company will have no
obligation to issue or deliver certificates for Shares under this Plan prior to:
(a) obtaining any approvals from governmental agencies that the Company
determines are necessary or advisable; and/or (b) completion of any registration
or other qualification of such Shares under any state or federal law or ruling
of any governmental body that the Company determines to be necessary or
advisable. The Company will be under no obligation to register the Shares with
the SEC or to effect compliance with the registration, qualification or listing
requirements of any state securities laws, stock exchange or automated quotation
system, and the Company will have no liability for any inability or failure to
do so.

          17.  NO OBLIGATION TO EMPLOY.  Nothing in this Plan or any Award
               -----------------------                                    
granted under this Plan will confer or be deemed to confer on any Participant
any right to continue in the employ of, or to continue any other relationship
with, the Company or any Parent or Subsidiary of the Company or limit in any way
the right of the Company or any Parent or Subsidiary of the Company to terminate
Participant's employment or other relationship at any time, with or without
cause.

          18.  CORPORATE TRANSACTIONS.
               ---------------------- 

               18.1 Assumption or Replacement of Awards by Successor.  In the
                    ------------------------------------------------         
event of (a) a dissolution or liquidation of the Company, (b) a merger or
consolidation in which the Company is not the surviving corporation (other than
a merger or consolidation with a wholly-owned subsidiary, a reincorporation of
the Company in a different jurisdiction, or other transaction in which there is
no substantial change in the stockholders of the Company or their relative stock
holdings and the Awards granted under this Plan are assumed, converted or
replaced by the successor corporation, which assumption will be binding on all
Participants), (c) a merger in which the Company is the surviving corporation
but after which the stockholders of the Company immediately prior to 

                                      -8-

                                                                  VeriSign, Inc.
                                                      1998 Equity Incentive Plan


such merger (other than any stockholder that merges, or which owns or controls
another corporation that merges, with the Company in such merger) cease to own
their shares or other equity interest in the Company, (d) the sale of
substantially all of the assets of the Company, or (e) the acquisition, sale, or
transfer of more than 50% of the outstanding shares of the Company by tender
offer or similar transaction, any or all outstanding Awards may be assumed,
converted or replaced by the successor corporation (if any), which assumption,
conversion or replacement will be binding on all Participants. In the
alternative, the successor corporation may substitute equivalent Awards or
provide substantially similar consideration to Participants as was provided to
stockholders (after taking into account the existing provisions of the Awards).
The successor corporation may also issue, in place of outstanding Shares of the
Company held by the Participant, substantially similar shares or other property
subject to repurchase restrictions no less favorable to the Participant. In the
event such successor corporation (if any) refuses to assume or substitute
Awards, as provided above, pursuant to a transaction described in this
Subsection 18.1, such Awards will expire on such transaction at such time and on
such conditions as the Committee will determine; provided, however, that the
                                                 --------  -------
Committee may, in its sole discretion, provide that the vesting of any or all
Awards granted pursuant to this Plan will accelerate. If the Committee exercises
such discretion with respect to Options, such Options will become exercisable in
full prior to the consummation of such event at such time and on such conditions
as the Committee determines, and if such Options are not exercised prior to the
consummation of the corporate transaction, they shall terminate at such time as
determined by the Committee.

          18.2 Other Treatment of Awards.  Subject to any greater rights granted
               -------------------------                                
to Participants under the foregoing provisions of this Section 18, in the event
of the occurrence of any transaction described in Section 18.1, any outstanding
Awards will be treated as provided in the applicable agreement or plan of
merger, consolidation, dissolution, liquidation, or sale of assets.

          18.3 Assumption of Awards by the Company.  The Company, from time to
               -----------------------------------                         
time, also may substitute or assume outstanding awards granted by another
company, whether in connection with an acquisition of such other company or
otherwise, by either; (a) granting an Award under this Plan in substitution of
such other company's award; or (b) assuming such award as if it had been granted
under this Plan if the terms of such assumed award could be applied to an Award
granted under this Plan. Such substitution or assumption will be permissible if
the holder of the substituted or assumed award would have been eligible to be
granted an Award under this Plan if the other company had applied the rules of
this Plan to such grant. In the event the Company assumes an award granted by
another company, the terms and conditions of such award will remain unchanged
(except that the exercise price and the number and nature of Shares issuable
 ------                                                                     
upon exercise of any such option will be adjusted appropriately pursuant to
Section 424(a) of the Code).  In the event the Company elects to grant a new
Option rather than assuming an existing option, such new Option may be granted
with a similarly adjusted Exercise Price.

          19.  ADOPTION AND STOCKHOLDER APPROVAL.  This Plan will become
               ---------------------------------                        
effective on the date on which the registration statement filed by the Company
with the SEC under the Securities Act registering the initial public offering of
the Company's Common Stock is declared effective by the SEC (the "Effective
Date").  This Plan shall be approved by the stockholders of the Company
(excluding Shares issued pursuant to this Plan), consistent with applicable
laws, within twelve (12) months before or after the date this Plan is adopted by
the Board.  Upon the Effective Date, the Committee may grant Awards pursuant to
this Plan; provided, however, that: (a) no Option may be exercised prior to
           --------  -------                                               
initial stockholder approval of this Plan; (b) no Option granted pursuant to an
increase in the number of Shares subject to this Plan approved by the Board will
be exercised prior to the time such increase has been approved by the
stockholders of the Company; and (c) in the event that stockholder approval of
such increase is not obtained within the time period provided herein, all Awards
granted pursuant to such increase will be canceled, any Shares issued pursuant
to any Award granted pursuant to such increase will be canceled, and any
purchase of Shares pursuant to such increase will be rescinded.

          20.  TERM OF PLAN/GOVERNING LAW.  Unless earlier terminated as
               --------------------------                                   
provided herein, this Plan will terminate ten (10) years from the date this Plan
is adopted by the Board or, if earlier, the date of stockholder approval. This
Plan and all agreements thereunder shall be governed by and construed in
accordance with the laws of the State of California.

          21.  AMENDMENT OR TERMINATION OF PLAN.  The Board may at any time
               --------------------------------                            
terminate or amend this Plan in any respect, including without limitation
amendment of any form of Award Agreement or instrument to be executed pursuant
to this Plan; provided, however, that the Board will not, without the approval
              --------  -------                                               
of the stockholders of the Company, amend this Plan in any manner that requires
such stockholder approval.

          22.  NONEXCLUSIVITY OF THE PLAN.  Neither the adoption of this Plan by
               --------------------------                                       
the Board, the submission of this Plan to the stockholders of the Company for
approval, nor any provision of this Plan will be construed as creating any
limitations on the power of the Board to adopt such additional compensation
arrangements as it may deem desirable, including, without limitation, the
granting of stock options and bonuses otherwise than under this Plan, and such

         Shares so purchased to pay for the exercise price and whereby the NASD
         Dealer irrevocably commits upon receipt of such Shares to forward the
         exercise price directly to the Company; or (2) through a "margin"

         Dealer irrevocably commits upon receipt of such Shares to forward the
         exercise price directly to the Company; or

    (f)  by any combination of the foregoing.]

          4.4      Tax Withholding.  Prior to the issuance of the Shares upon
                   ---------------                                           
exercise of this Option, Optionee must pay or provide for any applicable federal
or state withholding obligations of the Company.  If the Committee permits,
Optionee may provide for payment of withholding taxes upon exercise of this
Option by requesting that the Company retain Shares with a Fair Market Value
equal to the minimum amount of taxes required to be withheld.  In such case, the
Company shall issue the net number of Shares to the Optionee by deducting the
Shares retained from the Shares issuable upon exercise.

          4.5      Issuance of Shares.  Provided that the Exercise Agreement and
                   ------------------

authorized assignee, or Optionee's legal representative, and shall deliver
certificates representing the Shares with the appropriate legends affixed
thereto.

      5.  NOTICE OF DISQUALIFYING DISPOSITION OF ISO SHARES.  If this Option
          -------------------------------------------------                 
is an ISO, and if Optionee sells or otherwise disposes of any of the Shares
acquired pursuant to the ISO on or before the later of (a) the date two (2)
years after the Date of Grant, and (b) the date one (1) year after transfer of
such Shares to Optionee upon exercise of this Option, then Optionee shall
immediately notify the Company in writing of such disposition.

      [IF IMMEDIATELY EXERCISABLE:
      6.   REPURCHASE RIGHT.  The Company shall have the right to repurchase
           ----------------                                                 
all Unvested Shares held by Optionee if Optionee is Terminated.  The Company
shall exercise such repurchase right, if at all, within 90 days after the
Optionee's date of Termination for cash or cancellation of purchase money
indebtedness at the Optionee's original exercise price.]

       7.   COMPLIANCE WITH LAWS AND REGULATIONS.  The exercise of this Option
            ------------------------------------

securities laws and with all applicable requirements of any stock exchange on

                                                          Stock Option Agreement
 
to register or qualify the Shares with the Securities and Exchange Commission,
any state securities commission or any stock exchange to effect such compliance.

         8.   NONTRANSFERABILITY OF OPTION.  This Option may not be transferred
              ----------------------------                                     
in any manner other than by will or by the laws of descent and distribution and
may be exercised during the lifetime of Optionee only by Optionee.  The terms of
this Option shall be binding upon the executors, administrators, successors and
assigns of Optionee.

         9.   TAX CONSEQUENCES.  Set forth below is a brief summary as of the
              ----------------                                               
date the Board of Directors of the Company adopted the Plan of some of the
federal and California tax consequences of exercise of this Option and
disposition of the Shares.  THIS SUMMARY IS NECESSARILY INCOMPLETE, AND THE TAX
LAWS AND REGULATIONS ARE SUBJECT TO CHANGE.  OPTIONEE SHOULD CONSULT A TAX
ADVISOR BEFORE EXERCISING THE OPTION OR DISPOSING OF THE SHARES.

               9.1   Exercise of ISO.  If this Option qualifies as an ISO, there
                     ---------------   
will be no regular federal or California income tax liability upon the exercise
of this Option, although the excess, if any, of the fair market value of the
Shares on the date of exercise over the Exercise Price will be treated as a tax
preference item for federal income tax purposes and may subject the Optionee to
the alternative minimum tax in the year of exercise.

               9.2   Exercise of Nonqualified Stock Option.  If this Option does
                     -------------------------------------                      
not qualify as an ISO, there may be a regular federal and California income tax
liability upon the exercise of this Option.  Optionee will be treated as having
received compensation income (taxable at ordinary income tax rates) equal to the
excess, if any, of the fair market value of the Shares on the date of exercise
over the Exercise Price.  The Company will be required to withhold from
Optionee's compensation or collect from Optionee and pay to the applicable
taxing authorities an amount equal to a percentage of this compensation income
at the time of exercise.

               [IF IMMEDIATELY EXERCISABLE:
               9.3   Section 83(b) Election for Unvested Shares. With respect to
                     ------------------------------------------
Unvested Shares which are subject to repurchase pursuant to Section 6 of this
Agreement, unless an election is filed by the Optionee with the Internal Revenue
Service (and, if necessary, the proper state taxing authorities), within 30 days
                                                                  --------------
of the purchase of the Unvested Shares, electing pursuant to Code Section 83(b)
(and similar state tax provisions, if applicable) to be taxed currently on any
difference between the exercise price of the Unvested Shares and their Fair
Market Value on the date of exercise, there may be a recognition of taxable
income (including, where applicable, alternative minimum taxable income) to the
Optionee, measured by the excess, if any, of the Fair Market Value of the
Unvested Shares at the time they cease to be Unvested Shares, over the Exercise
Price of the Unvested Shares.]

               9.4   Disposition of Shares.  The following tax consequences may
                     ---------------------
apply upon disposition of the Shares.

                                                          Stock Option Agreement
 
                 a.     Incentive Stock Options.  If the Shares are held for
                        -----------------------                             
more than twelve (12) months after the date of the transfer of the Shares
pursuant to the exercise of an ISO and are disposed of more than two (2) years
after the Date of Grant, any gain realized on disposition of the Shares will be
treated as capital gain for federal and California income tax purposes. The
maximum federal capital gain tax rates are twenty eight percent (28%) for Shares
held more than twelve (12) months, but not more than eighteen (18) months ("MID-
TERM CAPITAL GAIN"), and twenty percent (20%) for Shares held for more than
eighteen (18) months ("LONG-TERM CAPITAL GAIN"). If Shares purchased under an
ISO are disposed of within the applicable one (1) year or two (2) year period,
any gain realized on such disposition will be treated as compensation income
(taxable at ordinary income rates) to the extent of the excess, if any, of the
Fair Market Value of the Shares on the date of exercise over the Exercise Price.

                 b.     Nonqualified Stock Options.  If the Shares are held for
                        --------------------------                             
more than twelve (12) months after the date of the transfer of the Shares
pursuant to the exercise of an NQSO, any gain realized on disposition of the
Shares will be treated as Mid-Term Capital Gain or Long-Term Capital Gain, as
the case may be.

                  c.    Withholding.  The Company may be required to withhold
                        -----------                                          
from Participant's compensation or collect from the Participant and pay to the
applicable taxing authorities an amount equal to a percentage of this
compensation income.

         10.  PRIVILEGES OF STOCK OWNERSHIP.  Optionee shall not have any of the
              -----------------------------                                     
rights of a shareholder with respect to any Shares until Optionee exercises this
Option and pays the Exercise Price.

         11.  INTERPRETATION.  Any dispute regarding the interpretation of this
              --------------                                                   
Agreement shall be submitted by Optionee or the Company to the Committee for
review.  The resolution of such a dispute by the Committee shall be final and
binding on the Company and Optionee.

         12.  ENTIRE AGREEMENT.  The Plan is incorporated herein by reference.
              ----------------                                                 
This Agreement and the Plan and the Exercise Agreement constitute the entire
agreement and understanding of the parties hereto with respect to the subject
matter hereof and supersede all prior understandings and agreements with respect
to such subject matter.

         13.  NOTICES.  Any notice required to be given or delivered to the
              -------

                                VERISIGN, INC.
                                        

                       1998 EMPLOYEE STOCK PURCHASE PLAN

                         As Adopted December 19, 1997


     1.  Establishment of Plan.  VeriSign, Inc. (the "Company") proposes to
grant options for purchase of the Company's  Common Stock to eligible employees
of the Company and its Participating Subsidiaries (as hereinafter defined)
pursuant to this Employee Stock Purchase Plan (this "Plan").  For purposes of
this Plan, "Parent Corporation" and "Subsidiary" (collectively, "Participating
Subsidiaries") shall have the same meanings as "parent corporation" and
"subsidiary corporation" in Sections 424(e) and 424(f), respectively, of the
Internal Revenue Code of 1986, as amended (the "Code").  "Participating
Subsidiaries" are Parent Corporations or Subsidiaries that the Board of
Directors of the Company (the "Board") designates from time to time as
corporations that shall participate in this Plan.  The Company intends this Plan
to qualify as an "employee stock purchase plan" under Section 423 of the Code
(including any amendments to or replacements of such Section), and this Plan
shall be so construed.  Any term not expressly defined in this Plan but defined
for purposes of Section 423 of the Code shall have the same definition herein.
A total of 500,000 shares of the Company's  Common Stock is reserved for
issuance under this Plan.  Such number shall be subject to adjustments effected
in accordance with Section 14 of this Plan.

     2.  Purpose.  The purpose of this Plan is to provide eligible employees of
the Company and Participating Subsidiaries with a convenient means of acquiring
an equity interest in the Company through payroll deductions, to enhance such
employees' sense of participation in the affairs of the Company and
Participating Subsidiaries, and to provide an incentive for continued
employment.

     3.  Administration.  This Plan shall be administered by the Compensation
Committee of the Board (the "Committee").  Subject to the provisions of this
Plan and the limitations of Section 423 of the Code or any successor provision
in the Code, all questions of interpretation or application of this Plan shall
be determined by the Committee and its decisions shall be final and binding upon
all participants.  Members of the Committee shall receive no compensation for
their services in connection with the administration of this Plan, other than
standard fees as established from time to time by the Board for services
rendered by Board members serving on Board committees.  All expenses incurred in
connection with the administration of this Plan shall be paid by the Company.

     4.  Eligibility.  Any employee of the Company or the Participating
Subsidiaries is eligible to participate in an Offering Period (as hereinafter
defined) under this Plan except the following:

         (a)  employees who are not employed by the Company or Participating
Subsidiaries ten (10) days before the beginning of such Offering Period, except
that employees who are employed on the effective date of the registration
statement filed by the Company with the Securities and Exchange Commission
("SEC") under the Securities Act of 1933, as amended (the "Securities Act")
registering the initial public offering of the Company's  Common Stock shall be
eligible to participate in the first Offering Period under the Plan;

         (b)  employees who are customarily employed for twenty (20) hours or
less per week;

         (c)  employees who are customarily employed for five (5) months or less
in a calendar year;

         (d)  employees who, together with any other person whose stock would be
attributed to such employee pursuant to Section 424(d) of the Code, own stock or
hold options to purchase stock possessing five percent (5%) or more of the total
combined voting power or value of all classes of stock of the Company or any of
its Participating Subsidiaries or who, as a result of being granted an option
under this Plan with respect to such Offering Period, would own stock or hold
options to purchase stock possessing five percent (5%) or more of the total
combined voting power or value of all classes of stock of the Company or any of
its Participating Subsidiaries; and

                                                                  VeriSign, Inc.
                                               1998 Employee Stock Purchase Plan

         (e)  individuals who provide services to the Company or any of its
Participating Subsidiaries as independent contractors who are reclassified as
common law employees for any reason except for federal income and employment tax
                                    ------ ---                                  
purposes.

     5.  Offering Dates. The offering periods of this Plan (each, an "Offering
Period") shall be of twenty-four (24) months duration commencing on February 1
and August 1 of each year and ending on January 31 and July 31 of each year;
provided, however, that notwithstanding the foregoing, the first such
- --------- -------                                                    
Offering Period shall commence on the first business day on which price
quotations for the Company's  Common Stock are available on the Nasdaq National
Market (the "First Offering Date") and shall end on January 31, 1999.  Except
for the first Offering Period, each Offering Period shall consist of four (4)
six-month purchase periods (individually, a "Purchase Period") during which
payroll deductions of the participants are accumulated under this Plan.  The
first Offering Period shall consist of no more than five and no fewer than three
Purchase Periods, any of which may be greater or less than six months as
determined by the Committee.  The first business day of each Offering Period is
referred to as the "Offering Date".  The last business day of each Purchase
Period is referred to as the "Purchase Date".  The Committee shall have the
power to change the duration of Offering Periods or Purchase Periods with
respect to offerings without stockholder approval if such change is announced at
least fifteen (15) days prior to the scheduled beginning of the first Offering
Period or Purchase Period to be affected.

     6.  Participation in this Plan.  Eligible employees may become participants
in an Offering Period under this Plan on the first Offering Date after
satisfying the eligibility requirements by delivering a subscription agreement
to the Company's treasury department (the "Treasury Department") not later than
five (5) days before such Offering Date unless a later time for filing the
subscription agreement authorizing payroll deductions is set by the Committee
for all eligible employees with respect to a given Offering Period.  An eligible
employee who does not deliver a subscription agreement to the Treasury
Department by such date after becoming eligible to participate in such Offering
Period shall not participate in that Offering Period or any subsequent Offering
Period unless such employee enrolls in this Plan by filing a subscription
agreement with the Treasury Department not later than five (5) days preceding a
subsequent Offering Date.  Once an employee becomes a participant in an Offering
Period, such employee will automatically participate in the Offering Period
commencing immediately following the last day of the prior Offering Period
unless the employee withdraws or is deemed to withdraw from this Plan or
terminates further participation in the Offering Period as set forth in Section
11 below.  Such participant is not required to file any additional subscription
agreement in order to continue participation in this Plan.

     7.  Grant of Option on Enrollment.  Enrollment by an eligible employee in
this Plan with respect to an Offering Period will constitute the grant (as of
the Offering Date) by the Company to such employee of an option to purchase on
the Purchase Date up to that number of shares of  Common Stock of the Company
determined by dividing (a) the amount accumulated in such employee's payroll
deduction account during such Purchase Period by (b) the lower of (i) eighty-
five percent (85%) of the fair market value of a share of the Company's  Common
Stock on the Offering Date (but in no event less than the par value of a share
of the Company's  Common Stock), or (ii) eighty-five percent (85%) of the fair
market value of a share of the Company's  Common Stock on the Purchase Date (but
in no event less than the par value of a share of the Company's  Common Stock),
provided, however, that the number of shares of the Company's  Common Stock
- --------- -------                                                          
subject to any option granted pursuant to this Plan shall not exceed the lesser
of (a) the maximum number of shares set by the Committee pursuant to Section
10(c) below with respect to the applicable Purchase Date, or (b) the maximum
number of shares which may be purchased pursuant to Section 10(b) below with
respect to the applicable Purchase Date.  The fair market value of a share of
the Company's  Common Stock shall be determined as provided in Section 8 hereof.

     8.  Purchase Price.  The purchase price per share at which a share of
Common Stock will be sold in any Offering Period shall be eighty-five percent
(85%) of the lesser of:

         (a)  The fair market value on the Offering Date; or

         (b)  The fair market value on the Purchase Date.

                                                                  VeriSign, Inc.
                                               1998 Employee Stock Purchase Plan


       For purposes of this Plan, the term "Fair Market Value" means, as of any
date, the value of a share of the Company's  Common Stock determined as follows:

         (a)  if such  Common Stock is then quoted on the Nasdaq National
              Market, its closing price on the Nasdaq National Market on the
              date of determination as reported in The Wall Street Journal;
                                                   ----------------------- 

         (b)  if such  Common Stock is publicly traded and is then listed on a
              national securities exchange, its closing price on the date of
              determination on the principal national securities exchange on
              which the  Common Stock is listed or admitted to trading as
              reported in The Wall Street Journal;
                          ----------------------- 

         (c)  if such  Common Stock is publicly traded but is not quoted on the
              Nasdaq National Market nor listed or admitted to trading on a
              national securities exchange, the average of the closing bid and
              asked prices on the date of determination as reported in The Wall
                                                                       --------
              Street Journal; or
              --------------    

         (d)  if none of the foregoing is applicable, by the Board in good
              faith, which in the case of the First Offering Date will be the
              price per share at which shares of the Company's  Common Stock are
              initially offered for sale to the public by the Company's
              underwriters in the initial public offering of the Company's
              Common Stock pursuant to a registration statement filed with the
              SEC under the Securities Act.

     9.  Payment Of Purchase Price; Changes In Payroll Deductions; Issuance Of
Shares.

         (a)  The purchase price of the shares is accumulated by regular payroll
deductions made during each Offering Period.  The deductions are made as a
percentage of the participant's compensation in one percent (1%) increments not
less than two percent (2%), nor greater than ten percent (10%) or such lower
limit set by the Committee.  Compensation shall mean base salary, commissions,
bonuses, incentive compensation and shift premiums not to exceed  $250,000 per
calendar year, provided however, that for purposes of determining a
participant's compensation, any election by such participant to reduce his or
her regular cash remuneration under Sections 125 or 401(k) of the Code shall be
treated as if the participant did not make such election.  Payroll deductions
shall commence on the first payday of the Offering Period and shall continue to
the end of the Offering Period unless sooner altered or terminated as provided
in this Plan.

         (b)  A participant may decrease or increase the rate of payroll
deductions during an Offering Period by filing with the Treasury Department a
new authorization for payroll deductions, in which case the new rate shall
become effective for the next payroll period commencing more than fifteen (15)
days after the Treasury Department's receipt of the authorization and shall
continue for the remainder of the Offering Period unless changed as described
below.  Such change in the rate of payroll deductions may be made at any time
during an Offering Period, but not more than one (1) change may be made
effective during any Offering Period.  A participant may increase or decrease
the rate of payroll deductions for any subsequent Offering Period by filing with
the Treasury Department a new authorization for payroll deductions not later
than fifteen (15) days before the beginning of such Offering Period.

         (c)  All payroll deductions made for a participant are credited to his
or her account under this Plan and are deposited with the general funds of the
Company. No interest accrues on the payroll deductions. All payroll deductions
received or held by the Company may be used by the Company for any corporate
purpose, and the Company shall not be obligated to segregate such payroll
deductions.

         (d)  On each Purchase Date, so long as this Plan remains in effect and
provided that the participant has not submitted a signed and completed
withdrawal form before that date which notifies the Company that the participant
wishes to withdraw from that Offering Period under this Plan and have all
payroll deductions accumulated in the account maintained on behalf of the
participant as of that date returned to the participant, the Company shall 

                                      -3-

                                                                  VeriSign, Inc.
                                               1998 Employee Stock Purchase Plan


apply the funds then in the participant's account to the purchase of whole
shares of Common Stock reserved under the option granted to such participant
with respect to the Offering Period to the extent that such option is
exercisable on the Purchase Date. The purchase price per share shall be as
specified in Section 8 of this Plan. Any cash remaining in a participant's
account after such purchase of shares shall be refunded to such participant in
cash, without interest; provided, however that any amount remaining in such
participant's account on a Purchase Date which is less than the amount necessary
to purchase a full share of Common Stock of the Company shall be carried
forward, without interest, into the next Purchase Period or Offering Period, as
the case may be. In the event that this Plan has been oversubscribed, all funds
not used to purchase shares on the Purchase Date shall be returned to the
participant, without interest. No Common Stock shall be purchased on a Purchase
Date on behalf of any employee whose participation in this Plan has terminated
prior to such Purchase Date.

         (e)  As promptly as practicable after the Purchase Date, the Company
shall issue shares for the participant's benefit representing the shares
purchased upon exercise of his or her option.

         (f)  During a participant's lifetime, such participant's option to
purchase shares hereunder is exercisable only by him or her.  The participant
will have no interest or voting right in shares covered by his or her option
until such option has been exercised.

     10. Limitations on Shares to be Purchased.

         (a)  No participant shall be entitled to purchase stock under this Plan
at a rate which, when aggregated with his or her rights to purchase stock under
all other employee stock purchase plans of the Company or any Subsidiary,
exceeds $25,000 in fair market value, determined as of the Offering Date (or
such other limit as may be imposed by the Code) for each calendar year in which
the employee participates in this Plan.  The Company shall automatically suspend
the payroll deductions of any participant as necessary to enforce such limit
provided that when the Company automatically resumes such payroll deductions,
the Company must apply the rate in effect immediately prior to such suspension.

         (b)  No more than two hundred percent (200%) of the number of shares
determined by using eighty-five percent (85%) of the fair market value of a
share of the Company's  Common Stock on the Offering Date as the denominator may
be purchased by a participant on any single Purchase Date.

         (c)  No participant shall be entitled to purchase more than the Maximum
Share Amount (as defined below) on any single Purchase Date.  Not less than
thirty (30) days prior to the commencement of any Offering Period, the Committee
may, in its sole discretion, set a maximum number of shares which may be
purchased by any employee at any single Purchase Date (hereinafter the "Maximum
Share Amount").  Until otherwise determined by the Committee, there shall be no
Maximum Share Amount.  In no event shall the Maximum Share Amount exceed the
amounts permitted under Section 10(b) above.  If a new Maximum Share Amount is
set, then all participants must be notified of such Maximum Share Amount prior
to the commencement of the next Offering Period.  Once the Maximum Share Amount
is set, it shall continue to apply with respect to all succeeding Purchase Dates
and Offering Periods unless revised by the Committee as set forth above.

         (d)  If the number of shares to be purchased on a Purchase Date by all
employees participating in this Plan exceeds the number of shares then available
for issuance under this Plan, then the Company will make a pro rata allocation
of the remaining shares in as uniform a manner as shall be reasonably
practicable and as the Committee shall determine to be equitable.  In such
event, the Company shall give written notice of such reduction of the number of
shares to be purchased under a participant's option to each participant affected
thereby.

         (e)  Any payroll deductions accumulated in a participant's account
which are not used to purchase stock due to the limitations in this Section 10
shall be returned to the participant as soon as practicable after the end of the
applicable Purchase Period, without interest.

                                                                  VeriSign, Inc.
                                               1998 Employee Stock Purchase Plan


     11. Withdrawal.

         (a)  Each participant may withdraw from an Offering Period under this
Plan by signing and delivering to the Treasury Department a written notice to
that effect on a form provided for such purpose.  Such withdrawal may be elected
at any time at least fifteen (15) days prior to the end of an Offering Period.

         (b)  Upon withdrawal from this Plan, the accumulated payroll deductions
shall be returned to the withdrawn participant, without interest, and his or her
interest in this Plan shall terminate.  In the event a participant voluntarily
elects to withdraw from this Plan, he or she may not resume his or her
participation in this Plan during the same Offering Period, but he or she may
participate in any Offering Period under this Plan which commences on a date
subsequent to such withdrawal by filing a new authorization for payroll
deductions in the same manner as set forth above for initial participation in
this Plan.

         (c)  If the purchase price on the first day of any current Offering
Period in which a participant is enrolled is higher than the purchase price on
the first day of any subsequent Offering Period, the Company will automatically
enroll such participant in the subsequent Offering Period.  Except with respect
to the first Offering Period, any funds accumulated in a participant's account
prior to the first day of such subsequent Offering Period will be applied to the
purchase of shares on the Purchase Date immediately prior to the first day of
such subsequent Offering Period.  With respect to the first Offering Period, any
funds accumulated in a participant's account prior to the first day of such
subsequent Offering Period will be applied to the purchase of shares on the
Purchase Date next following the first day of such subsequent Offering Period.
A participant does not need to file any forms with the Company to automatically
be enrolled in the subsequent Offering Period

     12. Termination of Employment.  Termination of a participant's employment
for any reason, including retirement, death or the failure of a participant to
remain an eligible employee of the Company or of a Participating Subsidiary,
immediately terminates his or her participation in this Plan.  In such event,
the payroll deductions credited to the participant's account will be returned to
him or her or, in the case of his or her death, to his or her legal
representative, without interest.  For purposes of this Section 12, an employee
will not be deemed to have terminated employment or failed to remain in the
continuous employ of the Company or of a Participating Subsidiary in the case of
sick leave, military leave, or any other leave of absence approved by the Board;
provided that such leave is for a period of not more than ninety (90) days or
- --------                                                                     
reemployment upon the expiration of such leave is guaranteed by contract or
statute.

     13. Return of Payroll Deductions.  In the event a participant's interest
in this Plan is terminated by withdrawal, termination of employment or
otherwise, or in the event this Plan is terminated by the Board, the Company
shall promptly deliver to the participant all payroll deductions credited to
such participant's account.  No interest shall accrue on the payroll deductions
of a participant in this Plan.

     14. Capital Changes.  Subject to any required action by the stockholders
of the Company, the number of shares of  Common Stock covered by each option
under this Plan which has not yet been exercised and the number of shares of
Common Stock which have been authorized for issuance under this Plan but have
not yet been placed under option (collectively, the "Reserves"), as well as the
price per share of Common Stock covered by each option under this Plan which has
not yet been exercised, shall be proportionately adjusted for any increase or
decrease in the number of issued and outstanding shares of  Common Stock of the
Company resulting from a stock split or the payment of a stock dividend (but
only on the  Common Stock) or any other increase or decrease in the number of
issued and outstanding shares of Common Stock effected without receipt of any
consideration by the Company; provided, however, that conversion of any
                              --------- -------                        
convertible securities of the Company shall not be deemed to have been "effected
without receipt of consideration".  Such adjustment shall be made by the
Committee, whose determination shall be final, binding and conclusive.  Except
as expressly provided herein, no issue by the Company of shares of stock of any
class, or securities convertible into shares of stock of any class, shall
affect, and no adjustment by reason thereof shall be made with respect to, the
number or price of shares of  Common Stock subject to an option.

    In the event of the proposed dissolution or liquidation of the Company, the
Offering Period will terminate immediately prior to the consummation of such
proposed action, unless otherwise provided by the Committee.  The

                                                                  VeriSign, Inc.
                                               1998 Employee Stock Purchase Plan


Committee may, in the exercise of its sole discretion in such instances, declare
that this Plan shall terminate as of a date fixed by the Committee and give each
participant the right to purchase shares under this Plan prior to such
termination. In the event of (i) a merger or consolidation in which the Company
is not the surviving corporation (other than a merger or consolidation with a
wholly-owned subsidiary, a reincorporation of the Company in a different
jurisdiction, or other transaction in which there is no substantial change in
the stockholders of the Company or their relative stock holdings and the options
under this Plan are assumed, converted or replaced by the successor corporation,
which assumption will be binding on all participants), (ii) a merger in which
the Company is the surviving corporation but after which the stockholders of the
Company immediately prior to such merger (other than any stockholder that
merges, or which owns or controls another corporation that merges, with the
Company in such merger) cease to own their shares or other equity interest in
the Company, (iii) the sale of substantially all of the assets of the Company or
(iv) the acquisition, sale, or transfer of more than 50% of the outstanding
shares of the Company by tender offer or similar transaction, the Plan shall
continue for all Offering Periods which began prior to the transaction and
shares will be purchased based on the fair market value of the surviving
corporation's stock on each Purchase Date (taking into account the exchange
ratio, where necessary).

    The Committee may, if it so determines in the exercise of its sole
discretion, also make provision for adjusting the Reserves, as well as the price
per share of  Common Stock covered by each outstanding option, in the event that
the Company effects one or more reorganizations, recapitalizations, rights
offerings or other increases or reductions of shares of its outstanding  Common
Stock, or in the event of the Company being consolidated with or merged into any
other corporation.

     15.  Nonassignability.  Neither payroll deductions credited to a
participant's account nor any rights with regard to the exercise of an option or
to receive shares under this 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 22 hereof) by the participant.  Any such
attempt at assignment, transfer, pledge or other disposition shall be void and
without effect.

     16.  Reports.  Individual accounts will be maintained for each participant
in this Plan.  Each participant shall receive promptly after the end of each
Purchase Period a report of his or her account setting forth the total payroll
deductions accumulated, the number of shares purchased, the per share price
thereof and the remaining cash balance, if any, carried forward to the next
Purchase Period or Offering Period, as the case may be.

     17.  Notice of Disposition.  Each participant shall notify the Company if
the participant disposes of any of the shares purchased in any Offering Period
pursuant to this Plan if such disposition occurs within two (2) years from the
Offering Date or within one (1) year from the Purchase Date on which such shares
were purchased (the "Notice Period").  Unless such participant is disposing of
any of such shares during the Notice Period, such participant shall keep the
certificates representing such shares in his or her name (and not in the name of
a nominee) during the Notice Period.  The Company may, at any time during the
Notice Period, place a legend or legends on any certificate representing shares
acquired pursuant to this Plan requesting the Company's transfer agent to notify
the Company of any transfer of the shares.  The obligation of the participant to
provide such notice shall continue notwithstanding the placement of any such
legend on the certificates.

     18.  No Rights to Continued Employment.  Neither this Plan nor the grant of
any option hereunder shall confer any right on any employee to remain in the
employ of the Company or any Participating Subsidiary, or restrict the right of
the Company or any Participating Subsidiary to terminate such employee's
employment.

the foregoing, RSA's obligations under this Section 3.4 shall terminate and be
of no further force or effect upon DCI's failure to make timely payments of all
costs and expenses incurred by RSA or its counsel under this Section 3.4.

     4.  FURTHER ASSISTANCE.  RSA agrees, at no charge to DCI, but at DCI's
         ------------------                                                
expense, (i) to sign and deliver to DCI such other documents as DCI considers
desirable to evidence the assignment of the foregoing rights to DCI and DCI's
ownership of such rights and property and (ii) to cooperate with DCI in
performing any lawful act or signing any document which DCI in its sole judgment
considers necessary to apply for, prosecute, obtain or enforce any patent,
copyright or other right of protection relating to any intellectual property.
In the event DCI is unable to secure RSA's signature on any such document, RSA
hereby irrevocably designates and appoints each of DCI and its duly authorized
agents as its attorney-in-fact, to act for and in its behalf and stead, for the
limited purpose of executing and filing any such document and doing all other
lawfully permitted acts to further the prosecution, issuance and enforcement of
patents, copyrights, or other protections with the same force and effect as if
executed and delivered by RSA.

proceeding against DCI on the basis of infringement of any United States patent,
copyright or trade secret in the field of cryptography by the software described
on Exhibit B delivered by RSA to DCI hereunder or any claim that RSA has no
   ---------                                                               
right to transfer and assign such software hereunder; and (ii) pay any final
judgment entered or settlement against DCI on such issue in any such suit or
proceeding defended by RSA.  RSA shall have no obligation to DCI pursuant to
this Section 7.1 unless:  (A)  DCI gives RSA prompt written notice of the claim;
(B)  RSA is given the right to control and direct the investigation,
preparation, defense and settlement of the claim; and  (C)  the claim is based

determined by any final judgment that RSA was not liable hereunder because of
such modifications, DCI shall reimburse RSA for all expenses incurred by it in
connection with this Section 7.1.

          7.2  If RSA receives notice of an alleged infringement, RSA shall have
the right, at its sole option, to obtain the right to continue use of the
software or to replace or modify the software so that it is no longer
infringing; provided, that such replacement or modified software performs
comparably to that which it replaces.

          7.3  WITHOUT LIMITING DCI'S RIGHTS AND REMEDIES UNDER ANY OTHER
AGREEMENT, THE RIGHTS AND REMEDIES SET FORTH IN SECTIONS 7.1 AND 7.2 CONSTITUTE

     1.7  ECAS means VeriSign's proprietary software product marketed and
          ----

2.   SCOPE
     -----

     2.1  VeriSign Will Migrate Existing Products and Services to Microsoft
Technology Platform.

          VeriSign will migrate its existing products and services to the
Microsoft Technology Platform during the normal course of planned system
upgrades and enhancements, provided the Microsoft Technology Platform is able to
met the technical requirements of the specific product or service.  The specific
products and services to be considered will include the following:

          A.   Digital ID Center operator tools will be migrated to Windows 95
               and Windows NT Workstation within 6 months of satisfaction of
               VeriSign technical requirements.

          B.   ***

          C.   Web pages on VeriSign Web sites that are accessed by customers
               using Microsoft Internet Explorer will be updated to include the
               use of ActiveX controls to perform enrollment and other
               operations within 6 months of satisfaction of VeriSign technical
               requirements.

     *** Confidential treatment has been requested with respect to certain
portions of this exhibit.  Confidential portions have been omitted from the
public filing and have been filed separately with the Securities and Exchange
Commission.

                                       3
<PAGE>
 
          D.   VeriSign will make best efforts to release the commercial version
               of ECAS on Microsoft NT Server and Microsoft Internet Information
               Server no later than one year after release on other platforms.
               Once ECAS is released on the Microsoft Technology Platform, new
               releases of ECAS will thereafter be released on such Microsoft
               Technology Platform with equivalent functionality and
               simultaneously with VeriSign's new releases on the then current
               Sun/Solaris platform.

          E.   VeriSign will make best efforts to migrate servers used by
               VeriSign to perform back-end operations (including signing
               servers, authentication servers, lifecycle management servers,
               but excluding Oracle database server) to Windows NT Server within
               one year of the satisfaction of VeriSign technical requirements.

          F.   VeriSign will make reasonable efforts to migrate its internal
               systems to Microsoft Windows 95, Windows NT Workstation, and
               Windows NT Server within one year after execution of this
               Agreement.  To the extent VeriSign migrates VeriSign internal
               systems, Microsoft will provide VeriSign the opportunity to
               acquire "Not for Resale" or "NFR" Microsoft software at published
               prices for NFR software to complete the migration.  VeriSign's
               use of the software will be subject to the terms and conditions
               of the End User License Agreement ("EULA") accompanying such
               software; provided however, any restrictions contained in the
               EULA against VeriSign's use of the software in a production
               environment shall not apply.

          G.   ***

          H.   ***


          In order to expedite the migration process, VeriSign will train up to
five (5) members of its technical staff to become Certified Microsoft
Professionals for Windows NT Server.  Microsoft will provide VeriSign with
access to training materials and programs for training of VeriSign's technical
staff at Microsoft's expense.

     2.2  ***


     *** Confidential treatment has been requested with respect to certain
portions of this exhibit.  Confidential portions have been omitted from the
public filing and have been filed separately with the Securities and Exchange
Commission.

          2.3  Microsoft Will Make VeriSign the Preferred Provider of Commercial
Certificate Authority Services Acquired by Customers through the Microsoft
Technology Platform.

          VeriSign will be Microsoft's Preferred Provider of commercial
Certificate Authority services that are necessary for the effective use of
Microsoft Products and services.  Preferred Provider status means that Microsoft
will use commercially reasonable efforts to provide preferential placement of
VeriSign services in Microsoft Products in initial and subsequent releases by
listing VeriSign services before any non-preferred providers in any listing of
service providers that is displayed in the product and in a distinguished form
(e.g., through default registration links, specific and unique graphics, logos,
sizing, ad banners, preferred CA WWW Page, etc.).  The parties recognize that
such preferential listing shall exclude situations such as programmatic
enumeration (such as in the case of trusted roots) due to design characteristics
of Microsoft's certificate management architecture.  The Microsoft Products may
include:

          .    Internet Explorer
          .    Internet Information Server
          .    Exchange mail client

          Microsoft may publish certain criteria that other Certificate
Authorities or other potential Preferred Providers must meet to be recognized as
a trusted Certificate Authority or a Preferred Provider on Microsoft Certificate
Authority pages or to be enabled in Microsoft Products, including bundling of
the trusted CA's root keys in such products.  Such criteria may include:
objectively reviewed and published a certification practice statement, audited
secure facilities and practices, third party accreditation, volume scaleability,
liability insurance, etc.  Prior to issuing final criteria for Certificate
Authorities and Preferred Provider status, Microsoft will provide to VeriSign
for review and comment its proposed criteria and consider VeriSign's comments if
provided in a timely manner.

     To attain and retain Preferred Provider status for commercial Certificate
Authority services in Microsoft Products, VeriSign must meet the following
criteria:

          A.   VeriSign must provide, within commercially reasonable
               limitations, a specific service that Microsoft deems necessary
               for the effective use of a Microsoft Product and must make that
               service available at the time of the first general availability
               beta release of the Microsoft Product.  VeriSign shall support
               Certificate services for all platforms for which the Microsoft
               Product is released.  The specified service must be available to
               customers in any geographic market in which Microsoft Product
               will be used whether the service is available directly through
               VeriSign's presence in such market or indirectly via the
               Internet, subject to the legal, infrastructure, or regulatory
               restrictions on CA products or services in those geographies.

          B.   If Microsoft, in its reasonable judgment, notifies VeriSign of
               deficiencies in the delivery of VeriSign services, VeriSign shall
               correct any such deficiencies in accordance with obligations
               specified in any applicable 

                                       5
<PAGE>
 
               Service Level Agreements (or substantially similar forms agreed
               to by the parties). Moreover, if the parties, for whatever
               reason, are not able to agree upon a Service Level Agreement for
               a particular service, or if the parties cannot agree upon the
               application or interpretation of an existing Service Level
               Agreement to a service, either party may escalate the issue to
               executives for the thirty (30) day period described below. In the
               event the parties cannot agree after such executive period,
               Microsoft shall reasonably specify or interpret VeriSign's
               obligation to address the deficiencies.

          C.   The VeriSign service must offer pricing and service quality
               similar to the pricing and quality of equivalent services
               provided by VeriSign competitors under similar terms and
               conditions.

     Microsoft at its sole discretion may develop relationships with alternative
providers for any technology or service.  However, an additional thirty (30) day
executive escalation period will be required before other providers may be
considered for Preferred Provider status due to VeriSign's lack of compliance
with the above.  Provided that VeriSign continues to be in compliance with the
above, for a period of twelve (12) months after the Effective Date of this
Agreement, VeriSign shall be the only Preferred Provider of Certificate
Authority services for Microsoft Products.

     2.4  Microsoft Will Make VeriSign the Preferred Provider of Commercial
Certificate Authority Services Acquired by Microsoft for Use in Products or
Services.

          Individual Microsoft operating units may require Certificate Authority
services for internal use or for inclusion in products or services for their
external customers.  Microsoft will provide VeriSign with (i) access to purchase
decision-makers in the Microsoft organization, and to executives responsible for
Microsoft's external distribution channels (including OEMs, VARs, system
integrators and resellers), (ii) designation by a Microsoft executive of
VeriSign as a Microsoft Preferred Provider of commercial Certificate Authority
Services and (iii) an e-mail introduction to VeriSign (in a form substantially
similar to Exhibit "A").  Examples of such products and services may include,
but are not limited to:

          .    Product registration
          .    The Microsoft.com web site and specific sections of the Web Site
                 such as the developer forum
          .    The MSWeb web site
          .    The Microsoft Network, and specific "channels" on MSN
          .    A Microsoft "passport" service
          .    Active Desktop content channels

     2.5  Microsoft and VeriSign Will Collaborate to Cross-Promote Each Other's
Products and Services.

          Microsoft and VeriSign will work together to develop marketing plans
which feature each other's products and services.  These marketing plans may
include, but not be limited to, the following variety of activities:

          .  Inclusion of VeriSign marketing materials in Microsoft seminars on
             Microsoft products which include VeriSign Certificate Authority
             services
          .  Advertisement of VeriSign services on The Microsoft Network at
             favorable pricing
          .  Advertisement of Microsoft products on the VeriSign Digital ID
             Center at favorable pricing
          .  Joint sales calls on mutual existing and prospective customers
          .  Joint participation in trade shows, at the invitation of individual
             product groups
          .  Joint participation in vertical market programs developed by the
             Microsoft Industry Marketing Group

          Specific written plans may be developed by mutual agreement from time
to time by the appropriate representatives of the product marketing
organizations for each company.

     2.6  Microsoft and VeriSign Will Collaborate to Develop New Certificate-
Based Technologies, Products and Services.

          Microsoft and VeriSign will explore in good faith the potential
development of new Certificate technologies, products, and services, including
but not limited to:

          .  Microsoft Certificate Server Add-on modules
          .  Microsoft Certificate Server gateways
          .  ECAS integration with Microsoft Certificate Server
          .  Authentication
          .  Code Signing
          .  Personalization/Demographics
          .  S.E.T. (or pre-SET)
          .  Digital Wallet
          .  Content Signing
          .  Smart Cards
          .  Internationalization
          .  Software Metering
          .  Coupons/attribute Certificates
          .  Executable Certificates

                                       7
<PAGE>
 
     In the event that Microsoft and VeriSign agree to cooperate on a new
Certificate-based technology, product or service, the parties will consider in
good faith an agreement to provide the other party with a time-to-market
advantage relative to competitors, as described in detail below.  Performance
enhancements to existing services and new Certificate-based technology developed
by VeriSign for release on a Microsoft Technology Platform will not involve such
market advantage.

          2.6.1  Performance Enhancements to Existing Services.  VeriSign will
develop performance enhancements that shall be implemented on Microsoft's
browsers at the same time as, if not before, any competing browser.  VeriSign
will not keep this development work confidential.  Microsoft has no
confidentiality obligation with respect to any publicly disclosed information
regarding this type of development work by VeriSign and can work with other
vendors who are making similar changes to their services at the same time
VeriSign is making such enhancements.  Example:  a standards change,
acceleration and improvement of execution of CA products and services.

          2.6.2  New VeriSign Service on a Microsoft Technology Platform.  This
section will apply in the event VeriSign wishes to develop at its own expense a
new product or service for use with Microsoft technology and wishes to keep this
development confidential until release.  VeriSign will identify the development
as confidential to Microsoft.  Microsoft will maintain strict confidentiality
regarding such VeriSign development until full commercial release of the
Microsoft Product containing the VeriSign service.  Following commercial
release, Microsoft will continue to maintain confidentiality regarding any
details not made public by VeriSign.

          2.6.3  Original Joint Development.  In the event VeriSign and
Microsoft work together to develop new products or services, both companies,
including developers for each, will work together on a confidential basis.
Strict confidentiality will be maintained by both parties until full commercial
release of the new product or service.  Following commercial release, each party
will continue to maintain confidentiality regarding any details not made public
by the other party.

          2.6.4  Ownership of Intellectual Property.  Each party shall retain
all right, title and interest in the technology which it owns as of the date of
this Agreement and all intellectual property embodied therein.  Nothing in this
Agreement shall preclude any party from independent development of any
technology without use of another party's confidential information or without
infringement of another party's intellectual property.  Each party shall be
responsible for providing its customers with appropriate patent infringement and
other intellectual property protection, if any, relating to its own technology
and products.  Prior to any original joint development under Section 2.6.3, the
parties shall agree on the right, title and interest in and to the resulting
products or services, and any intellectual property rights embodied therein.
Each party agrees to grant the other party any and all intellectual property
rights necessary, but only to the extent necessary, for the other party's
performance of its obligations under the terms of this Agreement.

     2.7  Process for Technical and Marketing Collaboration.

          Microsoft and VeriSign agree to use commercially reasonable efforts to
collaborate in the following ways:

          A.   Meet by mutual agreement from time to time to develop an agreed
               upon list of development priorities and commitments.  The
               participants in this meeting will review product and service
               plans, customer requirements, technical requirements and delivery
               schedules.

          B.   Cooperate on standards group initiatives.  Microsoft and VeriSign
               shall use commercially reasonable efforts to present a unified
               position to standards organizations whose primary focus is Public
               Key Infrastructure technology.  Representatives of Microsoft and
               VeriSign shall discuss issues and develop joint positions on
               critical issues prior to attending standards group meetings or
               posting to discussion forums frequented by individuals who are
               involved in standards organizations.  In the event that a
               representative of either party is the sole participant in a
               Public Key Infrastructure standards organization meeting, that
               person will provide a summary of the proceedings to a designated
               counterpart.

          C.   Coordinate to provide effective customer support.  For each
               product and service initiative, Microsoft and VeriSign will
               identify appropriate technical support contacts who will develop
               a plan to resolve customer problems which arise through the use
               of our respective products and services.

          D.   Provide early access to respective products and services.
               Microsoft and VeriSign will disclose to each other on a
               confidential and reasonable efforts basis (as determined by the
               disclosing party) plans for future products and services that may
               use or be used in connection with Certificate technology.
               Microsoft and VeriSign may extend invitations to each other to
               attend public conference and public technical design reviews of
               technology related to digital Certificates.

Microsoft shall issue press releases in connection with Microsoft Products which
provide access to VeriSign Certificate technology.  Either of the parties may at
any time make announcements which are required by applicable law, regulatory
bodies, or stock exchange or stock association rules, so long as the party so
required to make the announcement, promptly upon learning of such requirement,
notifies the other party of such requirement and discusses with the other party
in good faith the exact wording of any such announcement.  VeriSign grants
Microsoft the right to state publicly that VeriSign products and services work
with Microsoft Products to provide access to VeriSign Certificates.  Microsoft
