INTRODUCTION
 
     Worldtalk Communications Corporation, and its subsidiary (collectively
"Worldtalk" or the "Company") is an Internet security company focused on
providing e-mail security and policy management solutions that enable
organizations to safely and efficiently use the Internet for global business
communication. The Company's products include WorldSecure Server, an e-mail
firewall and security policy manager, WorldSecure Client, a desktop e-mail
encryption product, NetTalk, a Windows NT-based e-mail and directory server, and
NetJunction, a UNIX-based directory and messaging switch.
 
     During 1996, Worldtalk initiated a major product development program to
leverage the Company's technology base and expertise in UNIX-based e-mail
connectivity backbones and directory services to develop new Windows NT based
Internet e-mail security and connectivity products. These products, WorldSecure
Server and NetTalk, were released in 1997. During 1997, the Company experienced
a more rapid decline in its UNIX-based NetJunction product than had been
anticipated at the end of 1996. The Company believes that this was caused by a
combination of factors. These included a more rapid market shift from UNIX-based
systems to Windows NT-based systems and the desire of organizations to utilize
Internet standards-based technology to build corporate intranets in place of
private, proprietary network backbones. As a result, the Company experienced a
20.3% decline in revenue compared to 1996 and significant operating losses. The
Company's results improved by the fourth quarter of 1997 as a result of
increased revenue from the new Windows-NT based products and the implementation
of effective cost control measures. See Item 7 "Management's Discussion and
Analysis of Financial Condition and Results of Operation - Overview."
 
     The Company has experienced a significant shift in product mix from almost
100% of software license revenue coming from UNIX-based NetJunction products in
1996 to the majority of software license revenue coming from Windows NT-based
e-mail security and connectivity products in 1997. By the second half of 1998,
the Company anticipates that most of its development and marketing efforts will
be focused on the Windows NT-based security products. The Company also plans to
continue maintaining and supporting its NetJunction product line and believes
that there may be a continuing revenue stream from this activity for a limited
time in the future. Although the Company believes that the NetJunction product
line may continue to be viable in the marketplace, the Company plans to utilize
its resources to exploit the Internet security market.
 
     During 1998 and beyond, the Company expects to deploy resources to support
its reseller channel strategy and anticipates that an increasing percentage of
revenue will be derived from those channels.
 
E-MAIL SECURITY
 
     Worldtalk believes that business communications at all levels will
increasingly utilize the Internet to conduct day-to-day business communications.
The Company also believes that the majority of such communication will be made
via e-mail. Industry analysts estimate that e-mail accounts for about 70% of
network traffic.
 
                                        1
<PAGE>   3
 
     Unfortunately e-mail communication is not completely secure. Over the past
few years, the network firewall has served as the dominant solution to protect
networks from external attacks. But it has failed to fully protect e-mail
applications. This has made organizations vulnerable to attack from many
external sources. These organizations are equally vulnerable to malicious and
non-malicious attacks from inside their networks, since important corporate
information such as business plans, financial information, marketing and
engineering documents and other intellectual property can leave the organization
with the simple click of a mouse.
 
     Today, organizations are increasingly concerned about confidential
information, which can be publicly exchanged by employees via e-mail. Further,
certain industries are required by governmental and industrial regulatory
agencies to control, monitor and archive e-mail traffic. Law firms are concerned
about issues relating to attorney-client privilege and health care firms are
concerned about confidential patient information. Organizations are also
increasingly concerned about potential liability and other problems associated
with the introduction of undesirable material from the Internet, as well as
unwanted SPAM e-mail, which can cripple networks. The Company believes that
e-mail security and policy management improvement are key elements of realizing
the productivity and cost-savings advantages available through the use of e-mail
over the Internet. Worldtalk refers to this type of e-mail as "business-grade
e-mail."
 
THE WORLDTALK SOLUTION
 
     Worldtalk's products are aimed at providing a complete security and policy
management solution for e-mail systems allowing organizations to expand the
reach of their messaging systems and provide the necessary safety needed to
exchange e-mail across intranets, extranets and the public Internet. Worldtalk
solutions protect e-mail communication while attempting to guarantee privacy,
integrity and non-repudiation. Worldtalk solutions also provide the needed
directory and messaging connectivity to establish secure e-mail backbones.
 
     Worldtalk's innovative WorldSecure product family offers organizations an
e-mail firewall and policy management engine to enforce e-mail access, security
and encryption policies. Worldtalk's software products are complemented by its
Professional Services Organization (PSO) which offers a complete package of
consulting, custom engineering, training and educational services to meet
customer needs from initial planning and network design to system testing and
production implementation.
 
     Worldtalk's current product offerings include:
 
     WorldSecure Server -- The E-mail Firewall. WorldSecure Server consolidates
several security countermeasures such as encryption and digital signature,
access and content control, virus detection and protection, and archival
functions. WorldSecure also provides a management interface to define and manage
e-mail security and encryption policies.
 
     WorldSecure Client -- The Desktop to Desktop E-mail Security Solution.
WorldSecure Client provides S/MIME-based e-mail encryption and digital signature
for e-mail applications. Using the emerging S/MIME standards (endorsed by RSA,
Netscape, Microsoft, Worldtalk and VeriSign, among others), WorldSecure Client
encrypts and digitally signs e-mail messages to help ensure the authenticity and
privacy of the messages. Originators can gain assurance that only the intended
recipient(s) can read the message and recipients can validate that the message
is from the stated originator.
 
     NetTalk -- The Intranet E-mail and Directory Solution. NetTalk provides
messaging and directory connectivity between different e-mail systems. It also
provides storage of X.509 digital certificates for security applications. A
digital certificate is a password-protected, encrypted data file that includes
the name of the holder and other identification information, a public key that
can be used to verify the digital signature, the name of the issuer or
certification authority and the certificate's validity period.
 
     NetJunction -- The UNIX-based Enterprise Level Backbone and Directory
Solutions. NetJunction allows organizations to integrate all their proprietary
e-mail and directory applications and provide consolidated access to the
Internet and X.400 VANs.

SALES CHANNELS
 
     The Company's objective is to develop multiple channels of distribution
worldwide for its products. The Company has designed its distribution strategy
to address the specific requirements of small companies, departments and large
enterprises and matches the sales and distribution channels to each of the
Company's software product offerings. Historically, the Company has relied
primarily on its direct sales and service organization for the license and
installation of its products in North America. For international sales, the
Company has entered into non-exclusive distribution relationships with a number
of international distributors. In the future, the Company expects to utilize
resellers to a greater extent than in prior years. The Company's WorldSecure and
NetTalk products require significantly less consulting, integration and support
than the Company's NetJunction products. The Company believes, therefore, that
these products will appeal to various reseller channels. Of particular note, the
Company entered into reseller arrangements with Security Dynamics Technologies,
Inc. (SDTI), worldwide, ASCII Something Good Corporation (ASCII), in Japan and
The Peapod Group (Peapod) in Europe during 1997. In addition, the Company
recruited a number of VARs and other third-party resellers and plans to expand
these relationships in order to maximize sales of its new Windows NT products.
The Company also markets and sells its products through its telesales
organization.
 
     The Company's direct sales force primarily targets medium to large-sized
organizations with enterprise-wide LAN implementations, across all vertical
markets. These organizations represent significant sales opportunities for the
Company's current and future products. The direct sales process involves the
generation of leads through a combination of industry trade show participation,
direct mail and telemarketing programs, requests for proposals from prospects or
customer and channel referrals. The field sales force conducts multiple
presentations and demonstrations of the Company's products to management at the
customer's site. During 1997, the direct sales force has begun working with the
resellers noted above, as well as other VARs and systems integrators to sell the
Company's Windows NT-based WorldSecure and NetTalk products. Typical sales
cycles range from several weeks to six months, but may be significantly longer
for very large sales. At times, potential customers enter into 30-day evaluation
agreements with the Company, during which time the customer can evaluate the
software without charge. The Company also sells software upgrades and annual
maintenance agreements directly to customers, as well as through its
international distributors.
 
     During 1997, the Company utilized the Internet in a significant way to
market its Windows NT NetTalk and WorldSecure products. Potential customers can
now download 30-day evaluation copies of these products from the Company's web
site. Additionally, an increasing percentage of sales during 1997 came from the
Company's telesales group working in a team approach with the Company's direct
sales force.
 
     The Company also targeted three key vertical market segments during 1997:
the legal industry, healthcare organizations and financial institutions for
sales of the Company's Windows NT products. The Company believes that those
vertical market segments are among the first to see the need for e-mail
Internet/intranet security and policy management products.
 
INTERNATIONAL SALES
 
     International sales, which are denominated in U.S. dollars, accounted for
28%, 24% and 14% of the Company's total revenues in 1997, 1996 and 1995,
respectively. The Company has entered into distribution relationships with a
number of international distributors who do not have exclusive territories,
although, the reseller arrangements with both SDTI and ASCII have certain
exclusivity features. These distributors provide system installation, technical
support and systems integration services, as well as follow-on first-line
support to local customers. The Company expanded its international sales by
establishing a more extensive network of international distributors, entering
into agreements with third parties to provide customer service and support
internationally and develop localized versions of its products during 1997.
ASCII accounted for 10.2% of the Company's total revenues in 1997. No other
single international distributor or OEM accounted for greater than 10% of the
Company's revenues in 1997, 1996 or 1995.

MARKETING
 
     The Company uses its direct sales force, its internal telesales
organizations and resellers, in combination with a variety of marketing
programs, to stimulate demand for its software products. The Company seeks to
build awareness of its products through participation in industry trade shows
and conferences, publication of technical articles in the trade press and
communication with its installed base of customers. These programs are focused
on target markets and are supplemented by selected VARs, systems integrators and
international OEMs. In addition, the Company has developed domestic and
international co-marketing programs with key strategic partners designed to take
advantage of their complementary marketing capabilities. As noted above, the
Company launched a major vertical market initiative in the legal, healthcare and
financial industry segments during 1997. As of December 31, 1997, the Company
had 12 full-time personnel employed in sales and 10 full-time personnel employed
in marketing.
 
PROFESSIONAL SERVICES
 
     The Company established a professional services organization in 1995 to
manage the Company's on-site installation services and custom development
programs, offering customer training and professional consulting services to its
customer base. These services are delivered by a combination of full-time
Company employees and third-party consultants trained on Worldtalk applications,
which are intended to complement related integration services performed by the
Company's VARs, distributors and systems integrators. Professional services are
performed for an additional fee, and are offered in conjunction with the
licensing or deployment of Worldtalk's software products.
 
INSTALLATION AND CONSULTING
 
     The Company provides on-site installation and consulting services,
generally billing for such services on a time-and-materials basis. Standard
service contracts typically range from two to four weeks in duration and are
sold primarily to support the installation and initial deployment of Worldtalk
products. The Company also offers longer-term arrangements for those customers
interested in broader network planning or program management services.
 
TRAINING
 
     The Company offers monthly customer training classes for Worldtalk network
administrators and authorized resellers at the Company's headquarters in Santa
Clara, California, as well as customized on-site classes for large customers.
 
CUSTOM DEVELOPMENT
 
     From time to time, the Company provides custom development services to
customers who request unique or proprietary product extensions that enhance the
value of Worldtalk solutions in their networks. These services may be performed
by third-party integrators, consultants or Company employees, depending on the
nature and complexity of the request.
 
CUSTOMER MAINTENANCE AND SUPPORT
 
     The Company's software is generally deployed in mission critical
environments, where a high degree of customer support is important for the
continuing success of product deployment. The Company maintains a centralized
technical support group that is responsible for first-line telephone support as
well as distribution of product and documentation updates. This group works
closely with the Company's professional services and product development
organizations in order to ensure continuity in the areas of problem resolution
and priority response.
 
     Maintenance and support contracts, which are typically for twelve months,
are offered concurrently with the initial license of a Company product. These
contracts may be renewed annually and are generally priced at a fixed 15% to 20%
of the list price of the licensed software. In addition, per-incident and
service pack pricing
 
                                        4
<PAGE>   6
 
is available for the NetTalk and WorldSecure products. The Company also offers
customer support 24 hours a day, seven days a week, for those customers
requiring around the clock support. Pricing for such support is negotiated
separately and is in addition to the standard fee.
 
     The Company believes that customer support revenue will decline as a
percentage of total revenue during 1998 and beyond as the Company's new Windows
NT-based products require significantly less maintenance and support than the
more complex NetJunction products.
 
STRATEGIC RELATIONSHIPS
 
     The Company believes that strategic relationships with other technology
vendors and channels of distribution are important to the Company's business.
Accordingly, the Company has entered into strategic relationships with various
companies such as SDTI, ASCII, Peapod, ICL, Inc., RSA Data Security, VeriSign,
Inc. and Trend Micro, Inc. The Company plans to continue and to expand the
utilization of strategic technology licensing, marketing, distribution and other
business partnerships in the future.
 
PRODUCT DEVELOPMENT
 
     Since its inception, Worldtalk's product development efforts have focused
on developing a stable and robust core technology, such as the Worldtalk
directory and the surrounding architecture. Beginning in 1996, the Company began
a major product initiative to leverage its core technology to develop innovative
Internet e-mail security products. To accelerate this goal, the Company acquired
Deming Software, Inc. in November of 1996. Deming has significant expertise in
the area of cryptography and has played a key role in the development of the
WorldSecure product family.
 
     The Company's product development organization is grouped by key product
areas and is comprised of development engineers, quality assurance engineers and
technical writers. The approach used in product development is a phase-oriented
development process that includes formal engineering specifications, design test
documents, milestone inspections and quality control. This process incorporates
the monitoring of quality, schedules, functionality, costs and customer
satisfaction. The markets addressed by the Company's products are very sensitive
to quality and, therefore, the Company focuses on continuously improving product
quality.
 
     The Company continues to leverage its technical expertise and product
innovation capabilities to address user requirements for Internet e-mail
security products. While UNIX/NetJunction products have historically been the
core of the Company's business, the Company's new Windows NT-based Internet
e-mail security and connectivity products, which accounted for approximately 80%
of software license revenue in the fourth quarter of 1997. The Company believes
that this represents a positive trend relative to its product strategy and
direction.
 
     As of December 31, 1997, the Company had 27 full-time personnel employed in
product development. During 1997, 1996 and 1995, product development expenses
were $4.3 million, $3.6 million and $2.4 million, or 37.9%, 25.1% and 36.0% of
total revenues, respectively.
 
COMPETITION
 
     The market for the Company's products is intensely competitive and subject
to rapid change. The enterprise security market is targeted by various products
and solutions that compete with Worldtalk's e-mail security solutions. These
include products offered by Network Associates, Inc. and Integralis Technology,
Ltd.. The Company believes that its Windows NT product family competes favorably
with those products. With respect to the Company's NetJunction business, the
Company encounters competition principally from Control Data Systems, Inc. and
ISOCOR. The Company also anticipates competition in the future from other
companies in the enterprise security market as that industry continues to grow.
 
                                        5
<PAGE>   7
 
     The Company believes that the competitive factors affecting the market for
the Company's products and services include: product functionality and features;
product quality, performance and price; ease of product integration with
disparate e-mail and groupware solutions; quality of customer support services,
customer training and documentation; hardware platforms supported; vendor and
product reputation; and the strength of sales channels. The relative importance
of each of these factors depends upon the specific customer environment.
Although the Company believes that its products and services currently compete
favorably with respect to such factors, there can be no assurance that the
Company can maintain its competitive position against current and potential
competitors.
 
     Many of the Company's current and potential competitors have longer
operating histories; significantly greater financial, technical, product
development and marketing resources; greater name recognition and larger
customer bases than the Company. The Company's present or future competitors may
be able to develop products comparable or superior to those developed by the
Company. They may also be able to adapt more quickly than the Company to new
technologies, evolving industry trends or customer requirements, or devote
greater resources to the development, promotion and license of their products
than the Company.
 
INTELLECTUAL PROPERTY AND OTHER PROPRIETARY RIGHTS
 
     The Company's future success is dependent upon its proprietary software
technology. In addition, the Company licenses certain key technology from other
companies. The Company does not currently have any patents and relies
principally on trade secret, copyright and trademark laws, nondisclosure and
other contractual agreements and technical measures, to protect its technology.
The Company also believes that factors such as the technological and creative
skills of its personnel as well as new product developments and enhancements,
are essential to establishing and maintaining a technology leadership position.
The Company generally enters into confidentiality and/or license agreements with
its employees, distributors and customers. The Company limits access to and
distribution of its software, documentation and other proprietary information.
Much of the Company's software is shipped with a software security lock, which
initially limits software access to authorized users. In addition, the Company
restricts third party access to its source code, except in connection with
source code escrow arrangements. There can be no assurance that the steps taken
by the Company will prevent misappropriation of its technology, and such
protections do not preclude competitors from developing products with
functionality or features similar to the Company's products. Furthermore, there
can be no assurance that third parties will not independently develop competing
technologies that are substantially equivalent or superior to the Company's
technologies. The loss of any significant third-party license or the inability
to license additional technology as required, could have a material adverse
effect on the Company's results of operations until such time as the Company
could replace such technology.
 
EXPORT LICENSE REQUIREMENTS
 
     Export of the Company's WorldSecure product family is restricted by various
United States laws and regulations governing the export of encryption technology
administered principally by the United States Department of Commerce, Bureau of
Export Administration. The Company currently holds approved export licenses for
40-bit encryption for general export with the exclusion of certain industries
and countries and for 128-bit encryption for 25% or more owned subsidiaries of
United States companies with the exclusion of certain industries and certain
countries. The Company is currently in the process of applying for an export
license for 56-bit general export. The Company is also responsible for
monitoring customer compliance with these laws and regulations. Failure to
obtain necessary export license approval or future adverse changes in United
States government policy relative to the export of encryption technology could
materially decrease the Company's ability to compete in foreign markets thereby
adversely affecting revenue.
 
YEAR 2000 COMPLIANCE
 
     The Company believes that its products are or will be compliant with
customer requirements for operations through the year 2000 and beyond. Many
customers require such certification and warranties before purchasing products.
Failure of the Company's products to function through the year 2000 could cause
                                        6
<PAGE>   8
 
material liabilities to the Company to correct such defects. The Company does
not believe that any significant internal systems will be adversely affected by
the transition to years following 1999.
 
EMPLOYEES
 
     As of December 31, 1997, the Company had a total of 80 employees, of whom
22 were engaged in sales and marketing, 27 in research and development, 19 in
professional services and technical support and 12 in administration, finance,
MIS and operations. The Company's employees are not represented by labor unions,
nor are they generally bound by employment or noncompetition agreements or
covered by key-person life insurance policies. The Company has not experienced
any work stoppages and considers its relations with its employees to be good.
 
     The Company intends to continue to hire sales, marketing and engineering
personnel in the future. Competition for such personnel is intense, and there
can be no assurance that the Company can hire and retain qualified personnel in
the future. If the Company is unable to hire required personnel on a timely
basis, the Company's business, operating results and financial condition could
be adversely affected.
 
ITEM 2. PROPERTIES
 
     The Company's headquarters is located in Santa Clara, California, which
houses product development, sales, technical support and administrative
operations in approximately 30,000 square feet of space. This facility is under
lease through September 2005.
 
     The Company has leased sales offices in San Ramon, California; Chicago,
Illinois; New York, New York; and McLean, Virginia. The Company, through its
subsidiary, Deming Software, also has a leased engineering office in Bellevue,
Washington.
 
ITEM 3. LEGAL PROCEEDINGS
 
     The Company is engaged in certain legal actions arising in the ordinary
course of business. The Company believes that it has adequate legal defenses and
that ultimate outcome of these actions will not have a material effect on the

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS
 
OVERVIEW
 
     This discussion and analysis of financial condition and results of
operations contains descriptions of the Company's expectations regarding future
trends affecting its business. These forward-looking statements and other
forward-looking statements made elsewhere in this document are made in reliance
upon the safe harbor provisions of the Securities Litigation Reform Act of 1995.
The discussion in this report contains forward-looking statements that involve
risks and uncertainties. The Company's actual results may differ materially from
the results discussed in the forward-looking statements. Factors that could
cause or contribute to such differences include, but are not limited to, those
discussed below and in "Additional Factors That May Affect Future Results".
 
     The Company is an Internet security company focused on providing e-mail
security and policy management solutions that enable organizations to safely and
efficiently use the Internet for global business communication. The Company's
products include WorldSecure Server, an e-mail firewall and security policy
manager, WorldSecure Client, a desktop e-mail encryption product, NetTalk, a
Windows NT-based e-mail and directory server, and NetJunction, a UNIX-based
directory and messaging switch. During 1996, Worldtalk initiated a major product
development program to leverage the Company's technology base and expertise in
UNIX-based e-mail connectivity backbones and directory services to develop new
Windows NT-based Internet e-mail security and connectivity products. These
products, WorldSecure Server and NetTalk, were released in 1997. During 1997,
the Company experienced a more rapid decline in its UNIX-based NetJunction
product than had been anticipated at the end of 1996. The Company believes that
this was caused by a combination of factors. These included a more rapid market
shift from UNIX-based systems to Windows NT-based systems and the desire of
organizations to utilize Internet standards-based technology to build corporate
intranets in place of private, proprietary network backbones. As a result, the
Company experienced a 20.3% decline in revenue compared to 1996 and significant
operating losses in 1997. The Company's results improved by the fourth quarter
of 1997 as a result of increased revenue from the new Windows-NT based products
and the implementation of effective cost control measures.
 
     The Company has experienced a significant shift in product mix from almost
100% of software license revenue coming from UNIX-based NetJunction products in
1996 to the majority of software license revenue coming from Windows NT-based
e-mail security and connectivity products in 1997. However, a significant
portion of the revenue reported from these products during the fourth quarter
came from shipments of products pursuant to minimum non-refundable commitment
terms with two large resellers, which do not directly reflect sales to
end-users. During each quarter of 1998, the Company expects to report additional
revenue from the recognition of the balance of a non-refundable pre-paid
purchase commitment from one reseller based on product sell-through and
guaranteed quarterly minimum commitments from another reseller. The realization
of revenue in excess of the non-refundable prepaid amount noted above, will
depend on the success of these resellers in the marketplace. The Company
believes that a return to profitability will depend on increased market
acceptance of its new Windows NT-based e-mail security and policy management
products. Further revenue from these new Windows NT-based products will depend
increasingly on the success of third-party reseller channels. In this regard,
the Company entered into product distribution relationships in 1997 with Peapod
based in the United Kingdom, ASCII based in Japan, SDTI based in the United
States and various other resellers in the United States and in foreign markets.
A key element of the Company's future revenue growth will be the ability of the
Company's resellers to sell the Company's products in volume. There can be no
assurance that the Company's resellers will be successful in marketing these
products.
 
     By the second half of 1998, the Company anticipates that most of its
development and marketing efforts will be focused on the Windows NT-based
security products. The Company also plans to continue maintaining and supporting
its NetJunction product line and believes that there may be a continuing revenue
stream from this activity for a limited time in the future. Although the Company
believes that these products may continue to be viable in the marketplace, the
Company plans to utilize its resources to exploit the Internet security market.
 
                                       10
<PAGE>   12
 
     During 1998 and beyond, the Company expects to deploy resources to support
its reseller channel strategy and anticipates that an increasing percentage of
revenue will be derived from those channels.
 
     The Company's Windows NT-based Internet security and policy management
products will also place the Company into competition with a new set of vendors,
many of whom have significantly greater resources than the Company. Accordingly,
the Company intends to invest significantly in its business. As a result, there
can be no assurance that the Company will be profitable on a quarterly or annual
basis. The Company's future operating results may fluctuate due to factors such
as the demand for the Company's products; size and timing of customer orders;
success of the Company's resellers; the introduction of new products and product
enhancements by the Company or its competitors; the budgeting cycles of
customers; acceptance by the market of the Company's products; changes in United
States government policy on encryption software; changes in the proportion of
revenue attributable to license and service fees; changes in the level of
operating expenses; the ability of the Company to develop new distribution
channels; and competitive conditions in the industry.

</TABLE>
 
REVENUES
 
     The Company's total revenues are derived primarily from license fees for
its software and charges for services, including maintenance, customization
consulting, installation and training. License fees relate to both the initial
licenses of its software products, as well as subsequent purchases to expand
capacity or add functionality. Maintenance, installation and training revenues
relate to support contracts, installation and training services. Revenues from
software licenses are generally recognized upon shipment of
 
                                       11
<PAGE>   13
 
software. Revenues from maintenance contracts are recognized over the contract
term, which generally is one year, while installation and training revenues are
recognized when the services are performed. The Company also reported revenue
from shipments of products pursuant to minimum non-refundable commitment terms
with two large resellers.
 
     The Company's total revenues historically have been higher in the fourth
quarter of each fiscal year than in the first quarter of the following fiscal
year. The Company's management believes that this may continue for the
foreseeable future and may intensify depending upon a variety of factors
including the timing of new product introductions by the Company.
 
     The Company's total revenues were $11.3 million in 1997 as compared to
$14.2 million in 1996 and $6.7 million in 1995, representing a decrease of 20.3%
from fiscal 1996 to fiscal 1997 and an increase of 111.9% from fiscal 1995 to
fiscal 1996.
 
     Software license and software development revenues were $6.9 million in
1997 as compared $9.7 million in 1996 and $4.8 million for 1995, representing a
decrease of 29.4% from fiscal 1996 to fiscal 1997 and an increase of 100.9% from
fiscal 1995 to fiscal 1996. The decrease in software license and software
development revenues from fiscal 1996 to fiscal 1997 was primarily due to the
decline in sales of NetJunction enterprise backbone products which was not
offset rapidly enough by increased sales of the Company's new Windows NT-based
products, WorldSecure and NetTalk. The increase in software license and software
development revenues from fiscal 1995 to fiscal 1996 was attributable to
increased sales volumes while average selling prices stayed constant, and also
as a result of increased market acceptance of the Company's product offerings,
offset by decreases in software development revenue as the Company transitioned
out of that line of business.
 
     Maintenance, installation and training revenues were $4.5 million in 1997
as compared to $4.5 million in 1996 and $1.9 million in 1995, representing no
change from fiscal 1996 to fiscal 1997 and an increase of 140.2% from fiscal
1995 to fiscal 1996. Maintenance, installation and training revenue for fiscal
1997 was consistent with fiscal 1996 due to an increase in the number of
maintenance contracts associated with new software licenses, the renewal of
maintenance contracts by existing customers, and increases in demand for
customization consulting and training services. This increase was offset by weak
NetJunction sales in the second half of fiscal 1997, which resulted in reduced
consulting and integration services for the same period, along with an increase
in the percentage of total revenue from the sale of Windows NT-based products
which require less consulting and maintenance. The increase in maintenance,
installation and training revenues from fiscal 1995 to fiscal 1996 was
attributable to maintenance contracts associated with new software licenses, the
renewal of maintenance contracts by existing customers, and increases in demand
for customization consulting and training services. The Company expects that
maintenance, installation and training revenues will decline as a percentage of
revenue in the future as the Company increases sales of Windows NT-based e-mail
security and policy management products which require less maintenance,
installation and training.
 
COST OF REVENUES
 
     The Company's total cost of revenues was $4.0 million in 1997 as compared
to $3.4 million in 1996 and $1.8 million in 1995, representing increases of
16.1% and 88.1% from fiscal 1996 to fiscal 1997 and from fiscal 1995 to fiscal
1996, respectively.
 
     Cost of product revenues consists of the costs of royalties paid to
third-party vendors, product media and duplication, packaging materials and
shipping expenses. Cost of product revenues was $1.0 million in 1997, as
compared to $1.1 million in 1996 and $596,000 for 1995, representing a decrease
of 5.2% from fiscal 1996 to fiscal 1997 and an increase of 81.7% from fiscal
1995 to fiscal 1996. The slight decrease from fiscal 1996 to fiscal 1997 was due
to the decrease in license revenues, as the license costs fluctuate in direct
proportion to license revenues. This decrease was offset by certain fixed price
royalty arrangements with third-party vendors and other amortized costs related
to packaging materials, which do not fluctuate in direct proportion to license
revenues. The increase from fiscal 1995 to fiscal 1996 was due principally to
the mix of sales of royalty bearing software products and to the higher sales
volume in 1996.
 
                                       12
<PAGE>   14
 
     Maintenance, installation and training costs consist principally of
personnel-related costs for consulting, training and technical support.
Maintenance, installation and training costs were $3.0 million in 1997 as
compared to $2.4 million in 1996 and $1.2 million in 1995, representing
increases of 25.9% and 91.2% from fiscal 1996 to fiscal 1997 and from fiscal
1995 to fiscal 1996, respectively. These increases were due to the significant
expansion of the Company's customer service personnel across all categories,
including consulting, support and account management staff, offset by the
Company's later reduction of headcount early in the second half of 1997. The
Company expects that maintenance, installation and training costs will decline
as a percentage of revenue in the future, as the Company increases sales of
Windows NT-based e-mail security and policy management products which require
less maintenance, installation and training.
 
PRODUCT DEVELOPMENT
 
     Product development expenses consist primarily of personnel-related costs,
including salaries and benefits of personnel, as well as equipment and facility
costs. Product development expenses are incurred for the research, design and
development of new products, enhancements of existing products and quality
assurance activities. Costs related to research, design and development of
products are charged to product development expenses as incurred. Product
development expenses were $4.3 million in 1997 as compared to $3.6 million in
1996 and $2.4 million in 1995, representing increases of 20.5% and 47.5% from
fiscal 1996 to fiscal 1997 and from fiscal 1995 to fiscal 1996, respectively.
Product development expenses represented 37.9%, 25.1% and 36.0% of total
revenues for fiscal 1997, 1996 and 1995, respectively. The increases in absolute
dollars in product development were due to increased staffing and associated
support costs of software engineers and consultants required primarily to expand
product lines but secondarily to enhance the Company's existing product lines.
The fluctuations in product development expenses as a percentage of total
revenues were attributable to the fluctuations in revenues for the respective
periods and the fact that product development expenses do not fluctuate in
direct proportion to total revenues. The Company believes that continued
commitment to product development is required for the Company's products to
obtain a competitive advantage. The Company intends to continue to allocate
resources to product research and development. Consequently, such expenses may
increase in both dollar amounts and as a percentage of total revenues in the
future.
 
SALES AND MARKETING
 
     Sales and marketing expenses consist primarily of salaries, benefits, and
commissions of sales and marketing personnel, trade show expenses and
promotional expenses. Sales and marketing expenses were $7.4 million in 1997 as
compared to $6.8 million in 1996 and $4.8 million in 1995, representing
increases of 9.3% and 41.9% from fiscal 1996 to fiscal 1997 and from fiscal 1995
to fiscal 1996, respectively. Sales and marketing expenses represented 65.1%,
47.5% and 70.9% of total revenues for fiscal 1997, 1996 and 1995, respectively.
The increases in absolute dollars were primarily the result of the expansion of
the Company's marketing personnel and the launch of the Company's new Windows
NT-based e-mail security and policy management products. The fluctuations in
sales and marketing expenses as a percentage of total revenues were attributable
to the fluctuations in revenues for the respective periods and the fact that
certain sales and marketing expenses do not fluctuate in direct proportion to
total revenues. In the future, the Company expects to continue hiring additional
sales and marketing personnel, increase promotion and advertising efforts and
expand internationally through a combination of distributors, VARs and direct
sales personnel. Consequently, such expenses may increase in both dollar amounts
and as a percentage of total revenues in the future.
 
GENERAL AND ADMINISTRATIVE
 
     General and administrative expenses primarily consist of personnel costs
for finance and accounting, human resources and general management of the
Company. General and administrative expenses were $2.7 million in 1997 as
compared to $1.7 million in 1996 and $1.4 million in 1995, representing
increases of 55.2% and 25.9% from fiscal 1996 to fiscal 1997 and from fiscal
1995 to fiscal 1996, respectively. General and administrative expenses
represented 23.8%, 12.2% and 20.5% of total revenues for fiscal 1997, 1996 and
1995, respectively. The increases in absolute dollars were attributable
primarily to increased staffing and associated
 
                                       13
<PAGE>   15
 
expenses necessary to manage and support the Company's business, which included
public company related expenses. A secondary factor for this increase in
absolute dollars was the continuing amortization of goodwill related to the
acquisition of Deming Software, Inc. which occurred in the fourth quarter of
1996, as well as legal expenses and other costs associated with the negotiation
of new reseller arrangements. The fluctuations in general and administrative
expenses as a percentage of total revenues were attributable to the fluctuations
in revenue for the respective periods and the fact that general and
administrative expenses do not fluctuate in direct proportion to total revenues.
The Company believes that general and administrative expenses will continue to
increase in absolute dollar amounts in the future, as the Company expands its
staffing to handle increased infrastructure requirements.
 
     The Company's headcount increased rapidly from July 1996 through March
1997, as the Company continued to make strategic investments in product
development and distribution channels. These strategic investments were made to
meet the anticipated increase in demand for technical services following the
license revenue growth in 1996 for the UNIX-based NetJunction products, as well
as to develop and launch the Company's Windows NT-based products. The Company
reduced its headcount in the second half of 1997 due to the weak UNIX-based
NetJunction sales in the first half of 1997 and the transition of the Company's
business model to accommodate the new Windows NT-based e-mail security and
policy management products.
 
PURCHASED RESEARCH AND DEVELOPMENT
 
     In November 1996, the Company acquired Deming Software, Inc. for a total
purchase price of approximately $4.8 million of which $4.5 million was allocated
to purchased research and development. For allocation of the purchase price, see
Item 8 "Financial Statements and Supplemental Data, Note (2) of Notes to
Consolidated Financial Statements."
 
NET INTEREST INCOME
 
     Net interest income consists of interest income and expense and other
miscellaneous income and expense items. Net interest income was $508,000,
$544,000 and $31,000 for fiscal 1997, 1996 and 1995, respectively. The
fluctuations in net interest income from fiscal 1996 to fiscal 1997 and from
fiscal 1995 to fiscal 1996 were primarily attributable to fluctuations in the
Company's cash and cash equivalent and short-term investments balances, coupled
with interest rate fluctuations during the comparable periods.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     In April 1996, the Company completed its initial public offering of 2.1
million shares of Common Stock. The Company received net proceeds of
approximately $13.8 million, after deducting expenses which included
underwriting discounts and commissions. At December 31, 1997, the Company had
cash and cash equivalents of $4.7 million, short-term investments of $6.4
million and working capital of $6.6 million.
 
     The Company has a $2.0 million bank line of credit, which expired on
January 9, 1998. As of March 31, 1998 the Company had not yet renewed this line
of credit agreement. As of December 31, 1997, the Company had utilized $243,000
of its available line of credit.
 
     Net cash used in operating activities amounted to $2.5 million in 1997,
which was comprised principally of the Company's net loss of $6.7 million,
decreases in accounts payable, accrued expenses, and other liabilities of $1.2
million and an increase in prepaid expenses of $313,000, offset by an increase
in deferred revenue of $2.5 million, a decrease in accounts receivable of $2.5
million and depreciation and amortization of $745,000.
 
     Net cash used in investing activities amounted to $661,000 in 1997, which
included maturities of short-term investments of $7.0 million and an increase in
other assets of $247,000, offset by the purchase of short-term investments of
$7.4 million and $520,000 for purchases of property and equipment. The Company
currently has no significant capital commitments for fiscal 1998.
 
                                       14
<PAGE>   16
 
     Net cash provided by financing activities amounted to $810,000 in 1997
which included repayments of stockholder receivables of $265,000, net proceeds
from the issuance of common stock of $653,000, proceeds from bank borrowings of
$243,000, offset by principal payments under capital lease obligations of
$351,000.
 
     The Company may, in the future, pursue acquisitions of complementary
companies or technologies, or divest certain products and related services, to
further strategic corporate objectives. Such transactions could result in a
significant use of cash and earnings per share dilution caused by reduced
interest income and/or the issuance of additional stock. Additionally, costs
associated with the acquisition or divestiture of companies, products and
related services or technologies could materially impact future operating
results. Further, such acquisitions could result in the immediate write-off of
research and development in process and expenses relating to integration costs.
Such costs could result in significant losses in one or more fiscal quarters.
 
     The Company believes that its cash balances and credit facilities will be
sufficient to meet its anticipated cash needs to fund operating losses, working
capital requirements, capital expenditures and business expansion for at least
the next twelve months. Thereafter, if cash generated from operations is
insufficient to satisfy the Company's liquidity requirements, the Company may
seek to sell additional equity or convertible debt securities or obtain
additional credit facilities. The sale of additional equity or convertible debt
securities could result in additional dilution to the Company's stockholders and
may not be available on terms favorable to the Company if at all.
 
ADDITIONAL FACTORS THAT MAY AFFECT FUTURE RESULTS
 
     The Company was founded in February 1992 and has incurred operating losses
in each of its fiscal years since inception and had an accumulated deficit of
$23.7 million as of December 1997. The Company's prospects must be considered in
light of the risks, expenses and difficulties frequently encountered by
companies in the early stage of development, particularly companies in new and
rapidly evolving markets. There can be no assurance that the Company will be
successful in addressing such risks.
 
     The Company's quarterly and annual operating results have in the past, and
may in the future, vary significantly depending on many factors. Historically, a
substantial portion of the Company's revenues has been recognized in the last
two weeks of the third month of the quarter as a result of many customers'
purchasing practices. The inability of the Company to recognize expected
revenues during the last month of the quarter could result in substantial
fluctuations from period to period. The Company anticipates that its marketing
strategy of its Windows NT-based products will, in the future, depend more
significantly on distribution by third-party resellers and on managing the
distribution channel. In addition, significant revenue was reported during the
second half of 1997 from non-refundable minimum commitments from two large
resellers which do not directly reflect sales to end-users. During each quarter
of 1998, the Company expects to report additional revenue from the recognition
of the balance of a non-refundable pre-paid purchase commitment from one
reseller based on product sell-through and guaranteed quarterly minimum
commitments from another reseller. The realization of revenue in excess of the
non-refundable prepaid amount noted above, will depend on the success of these
resellers in the marketplace. The Company believes that a return to
profitability will depend on increased market acceptance of its new Windows
NT-based e-mail security and policy management products. Failure of the
Company's resellers to successfully market the Company's products would cause a
material adverse effect on the Company's anticipated future revenue, and there
can be no assurance that the Company's resellers will be successful in marketing
the Company's products. Additional factors that may affect operating results
include the timing of customers' decision-making processes, the timing of
research, development and marketing expenses in relation to product releases,
the timing of product introductions by the Company and its competitors, market
acceptance of new versions of the Company's products, product mix and general
economic factors. Any unfavorable changes in these or other factors could have a
material adverse effect on the Company's business, financial condition and
results of operations.
 
     The Company's success also depends on the performance of management and key
personnel. There have been several executive level changes during 1997. A key
element in the Company's future success is the ability of the Company's
management team to implement the Company's business strategy.
 
                                       15
<PAGE>   17
 
     The Company's success is also dependent upon market acceptance of its
products in preference to competing products and products that may be developed
by others. There can be no assurance that the Company will be successful in
developing and marketing product enhancements or new products that respond to
technological change, evolving industry standards and changing customer
requirements or that such new products will achieve a sufficient level of market
acceptance to result in profitable operations. In addition, the introduction or
announcement of new product offerings by the Company or its competitors could
cause customers to defer or cancel purchases of existing Company products.
Failure of the Company to develop and introduce new products and product
enhancements in a timely and cost-effective manner or to anticipate and respond
adequately to changing market conditions, as well as any significant delay in
product development or introduction, could cause customers to delay or decide
against purchases of the Company's product, which could have a material adverse
effect on the Company's business, financial condition and results of operations.
 
     The Company's future operating results are significantly dependent upon
market acceptance of its new Windows NT-based e-mail security and policy
management products. The Company believes that the introduction of these new
products and the development of new sales channels during the second and third
quarters of fiscal 1997 began the process of restoring the Company to a pattern
of growth. However, there can be no assurance that the Company will be
successful in this regard in the future.
 
     There are a number of factors that must be addressed for the Company's
products to achieve broad market acceptance. These factors include performance,
functionality, interoperability, price and the customer's assessment of the
Company's technical, managerial, service and support expertise and capability.
Failure to succeed with respect to any of these factors could result in the
Company failing to achieve broad market acceptance of its products, which could
have a material adverse effect on the Company's future revenue growth.
 
     International sales accounted for 28% of the Company's total sales in 1997,
compared to 24% in 1996 and it is not certain that revenues from the licensing
and support of the Company's products in international markets will continue to
grow. International sales involve a number of risks, including the impact of
possible recessionary environments in economies outside of the United States,
longer receivables collection periods, unexpected changes in regulatory
requirements, reduced protection for intellectual property rights in some
countries, tariffs and other trade barriers. Exports of the Company's
WorldSecure products require export licenses from the United States Department
of Commerce, Bureau of Export Administration. These licenses contain certain
restrictions as well as administrative requirements which must be assumed by the
Company. Export of "strong encryption" products requires that the Company comply
with certain key recovery requirements imposed by the United States government.
There is no assurance that the Company will be successful in obtaining
additional licenses. Failure to do so would adversely affect international sales
of the Company's WorldSecure products. Additionally, United States government
policy relative to encryption software is subject to change and any change
resulting in increased restrictions could adversely affect sales of the
Company's WorldSecure products. Recently Network Associates, a competitor,
announced that it would allow its Dutch subsidiary to begin selling an
international version of a strong encryption program, which it maintains does
not require a Department of Commerce approved export license. To the extent that
Network Associates is successful with this position, other companies, including
Worldtalk, would be at a competitive disadvantage in foreign markets for some
period of time, possibly resulting in lower than anticipated sales. There can be
no assurance that the Company will be able to sustain or increase revenue
derived from international licensing and service. Any failure to expand sales in
foreign markets, and the risks of doing business in those markets, could have a
material adverse effect on the Company's business, financial condition and
results of operations.

                          INDEPENDENT AUDITOR'S REPORT
 
The Board of Directors and Stockholders
Worldtalk Corporation:
 
     We have audited the accompanying consolidated balance sheets of Worldtalk
Corporation and subsidiary as of December 31, 1997 and 1996, and the related
consolidated statements of operations, stockholders' equity (deficit), and cash
flows for each of the years in the three-year period ended December 31, 1997. In
connection with our audits of the consolidated financial statements, we also
have audited the financial statement schedule listed in the Index at Item
14(a)(2). These consolidated financial statements and financial statement
schedule are the responsibility of the Company's management. Our responsibility
is to express an opinion on these consolidated financial statements and
financial statement schedule 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 from
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 Worldtalk
Corporation and subsidiary as of December 31, 1997 and 1996, and the results of
their operations and their cash flows for each of the years in the three-year
period ended December 31, 1997, in conformity with generally accepted accounting
principles. Also, in our opinion, the related financial statement schedule, when
considered in relation to the basic consolidated financial statements taken as a
whole, presents fairly, in all material respects, the information set forth
therein.

                  YEARS ENDED DECEMBER 31, 1997, 1996 AND 1995
               (ALL AMOUNTS IN THOUSANDS, EXCEPT PER SHARE DATA)
 
(1) SUMMARY OF THE COMPANY AND SIGNIFICANT ACCOUNTING POLICIES
 
  The Company
 
     Worldtalk Corporation (the "Company") is an Internet security company
focused on providing e-mail security solutions that enable organizations to
safely and efficiently use the Internet for global business communication. The
Company's products include WorldSecure Server, an e-mail firewall and security
policy manager, WorldSecure Client, a desktop e-mail encryption product,
NetTalk, a Windows NT-based e-mail and directory server, and NetJunction, a
UNIX-based directory and messaging switch.
 
  Basis of Presentation
 
     The accompanying consolidated financial statements include the accounts of
the Company and its wholly owned subsidiary. All significant intercompany
transactions and accounts have been eliminated in consolidation.
 
  Use of Estimates
 
     The preparation of 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 financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
  Financial Instruments and Concentration of Credit Risk
 
     Cash equivalents consist of highly liquid investments, principally money
market accounts and marketable debt securities, with maturities of three months
or less at the time of purchase.
 
     The Company has classified its short-term marketable investments as
"available-for-sale." Available-for-sale securities are carried at fair market
value, with material unrealized gains and losses, net of tax, reported in a
separate component of stockholders' equity. Gains and losses on securities sold
are based on the specific identification method.
 
     Fair values of short-term marketable investments are based on quoted market
values as of December 31, 1997 and 1996. As of December 31, 1997 and 1996, the
difference between the fair value and amortized cost of short-term marketable
investments was not material. As of December 31, 1997, short-term marketable
investments consisted of U.S. government securities due within one year or less.
 
     Financial instruments, which potentially subject the Company to
concentrations of credit risk, are primarily cash equivalents, short-term
marketable investments and accounts receivable. The Company's cash equivalents
and short-term marketable investments are primarily in U.S. treasury notes and
federal government agency obligations that have various maturities during 1998.
Concentrations of credit risk with respect to trade receivables are limited due
to the large number of customers comprising the Company's customer base and
their dispersion across different industries and geographic areas. Generally,
the Company requires no collateral on trade receivables. The Company believes
that its credit evaluation process substantially mitigates any credit risks.
 
  Property and Equipment
 
     Property and equipment are recorded at cost. Depreciation is provided using
the straight-line method over the estimated useful lives of the related assets,
generally three to five years. Equipment recorded under capital

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
                  YEARS ENDED DECEMBER 31, 1997, 1996 AND 1995
               (ALL AMOUNTS IN THOUSANDS, EXCEPT PER SHARE DATA)
 
leases and leasehold improvements are amortized using the straight-line method
over the shorter of the respective useful lives of the assets or the lease term.
 
     Effective January 1, 1996, the Company adopted Statement of Financial
Accounting Standards (SFAS) No. 121, Accounting for the Impairment of Long-Lived
Assets and for Long-Lived Assets to be Disposed Of. SFAS No. 121 requires the
Company to review the recoverability of the carrying amount of its long-lived
assets whenever events or changes in circumstances indicate that the carrying
amount of an asset might not be recoverable. In the event that facts and
circumstances indicate that the carrying amount of long-lived assets may be
impaired, an evaluation of recoverability would be performed. If an evaluation
is required, the estimated future undiscounted cash flows associated with the
asset would be compared to the asset's carrying amount to determine if a
write-down is required. Long-lived assets would then be written down to the
amount determined by reference to discounted future cash flows over the
remaining useful life of the related asset. Adoption of SFAS No. 121 did not
have a material effect on the Company's consolidated financial position or
results of operations in 1996. To date, the Company has made no adjustments to
the carrying values of its long-lived assets.
 
  Revenue Recognition
 
     The Company's revenue recognition policies are in accordance with Statement
of Position 91-1 Software Revenue Recognition and are as follows:
 
     -  Software licenses revenues are recognized upon shipment of the software.
        For licenses, which provide for a trial period using a temporary key,
        revenue is recognized upon delivery of a permanent key. Software license
        revenues are not recognized until there is a signed license agreement,
        the sales price is collectible and the company has no remaining
        significant vendor obligations.
 
     -  Maintenance revenues relating to contracts which entitle customers to
        receive technical support and future enhancements of the computer
        software are deferred and recognized ratably over the contract period.
 
     -  Installation and training revenues are recognized when the services are
        performed.
 
     -  Software development contract revenues are recognized using the
        percentage of completion method. The Company periodically evaluates
        estimated costs of completion and accrues the excess of estimated costs
        over anticipated contract revenue.
 
     In October 1997, the American Institute of Certified Public Accountants
(AICPA) issued Statement of Position (SOP) 97-2, Software Revenue Recognition,
which supersedes SOP 91-1. SOP 97-2 is effective for transactions entered into
after December 31, 1997. SOP 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 is still considering the effect of
adopting SOP 97-2; however, the Company generally does not anticipate that it
will have a material impact on the Company's consolidated results of operations
or financial position.
 
  Research and Development
 
     Development costs incurred in the research and development of new software
products and enhancements to existing software products are expensed as incurred
until technological feasibility in the form of a
 
                                       25

                      WORLDTALK CORPORATION AND SUBSIDIARY
 
             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
                  YEARS ENDED DECEMBER 31, 1997, 1996 AND 1995
               (ALL AMOUNTS IN THOUSANDS, EXCEPT PER SHARE DATA)
 
working model has been established. To date, the Company's software development
has been completed concurrent with the establishment of technological
feasibility, and, accordingly, no costs have been capitalized.
 
  Stock-Based Compensation
 
     The Company accounts for its stock option plans using the intrinsic value
method. As such, compensation expense is recorded if on the date of grant the
current market price of the underlying stock exceeds the exercise price.
 
  Income Taxes
 
     The Company uses the asset and liability method of accounting for income
taxes. Deferred tax assets and liabilities are recognized for the estimated
future tax consequences attributable to differences between the financial
statement carrying amounts of existing assets and liabilities and their
respective tax bases. Deferred tax assets and liabilities are measured using
enacted tax rates in effect for the year in which those temporary differences
are expected to be recovered or settled. Deferred tax assets are reduced by an
allowance to an amount whose realization is more likely than not.
 
  Earnings per Share
 
     Earnings per share (EPS) has been computed in accordance with Statement of
Financial Accounting Standards (SFAS) No. 128, Earnings Per Share. SFAS No. 128
requires the presentation of basic and diluted EPS. Basic EPS is computed using
the weighted average number of common shares outstanding during the period.
Diluted earnings per share is computed using the weighted average number of
potentially dilutive common equivalent shares outstanding for the period, if
any. For the years ending December 31, 1997, 1996 and 1995, common stock options
totaling 1,853, 1,251 and 827, respectively, were omitted from the computation,
as their impact would be antidilutive. Additionally, for the period ended
December 31, 1995, 6,025 shares of redeemable convertible preferred stock were
omitted from the computation, as their impact would be antidilutive.
 
     Effective February 3, 1998, the Securities and Exchange Commission (SEC)
issued Staff Accounting Bulletin (SAB) No. 98, which changes the calculation of
earnings per share in periods prior to initial public offerings, as previously
applied under SAB No. 83. When a registrant issued common stock, warrants,
options or other potentially dilutive instruments for consideration or with
exercise prices below the initial public offering price, within a one-year
period prior to the initial filing of a registration statement relating to an
initial public offering, SAB No. 83 required such equity instruments to be
treated as outstanding for all periods presented in the filing using the
anticipated initial public offering price and the treasury stock method. Under
SAB No. 98, when common stock, options, warrants or other potentially dilutive
instruments have been issued for nominal consideration during the periods
covered by income statements in the filing, those nominal issuances are to be
reflected in earnings per share calculations for all periods presented. The
Company has concluded that during all periods prior to the Company's initial
public offering, no equity instruments were issued for nominal consideration.
Net loss per share for periods prior to the Company's initial public offering
have been restated in accordance with SAB No. 98 and SFAS No. 128.
 
  Reclassifications
 
     Certain reclassifications were made to the 1996 and 1995 consolidated
financial statements to conform to the 1997 presentation.

(2) BUSINESS COMBINATION
 
     In November 1996, the Company acquired all of the outstanding stock of
Deming Software, Inc. (Deming), a privately held company specializing in the
development of electronic mail security software for the Internet, for a total
purchase price of $4,773, including 569 shares of the Company's common stock,
$225 in cash, and $418 of direct acquisition costs. The acquisition was
accounted for using the purchase method, and accordingly, the operating results
of Deming have been included in the consolidated financial statements of the
Company from the date of the acquisition. The purchase price has been allocated
as follows:

</TABLE>
 
     The $4,500 allocated to purchased research and development was charged to
operations in the quarter ended December 31, 1996. The amount allocated to
goodwill, covenant not to compete and workforce in place will be amortized using
the straight-line method over 48 months.
 
     The following pro forma combined results of operations for the years ended
December 31, 1996 and 1995 are presented as if the acquisition had occurred at
the beginning of each period. The pro forma results of operations for the year
ended December 31, 1995, include the results of operations of Deming from its
inception at December 11, 1995. The charge for in process research and
development has not been reflected in the following pro forma summary. The pro
forma summary does not necessarily reflect the results of operations as if the
Company and Deming had been consolidated during such periods:

     The net change in the valuation allowance for the year ended December 31,
1997 was an increase of $2,574. Deferred tax assets as of December 31, 1997
include approximately $303 relating to stock option compensation, which will be
credited to stockholders' equity when realized.
 
     For federal income tax purposes, the Company has net operating loss
carryforwards of approximately $6,736, expiring in the tax years 2008 through
2011. For California income tax purposes, the Company has net operating loss
carryforwards of approximately $2,247, expiring in the tax years 1997 through
2002. The

Company has a taxable year ending March 31 but reports on the calendar year for
financial statement purposes. The difference between the net operating loss
carryforward for federal income tax purposes and for state income tax purposes
results primarily from a 50% limitation on the California loss carryforwards.
 
     The Company has research and development tax credit carryforwards for
federal and California tax purposes of approximately $633 and $457,
respectively.
 
     Internal Revenue Code Section 382 limits the utilization of net operating
losses incurred prior to an "ownership change," as defined. The Company believes
an ownership change resulted from the issuance of the Series B preferred stock
on December 31, 1993.
 
     The Company has not yet determined whether an ownership change occurred due
to an initial public offering in April 1996. If an ownership change has
occurred, utilization of the net operating loss carryforwards could be
significantly reduced.
 
(6) BANK BORROWINGS AND CONVERTIBLE SECURED PROMISSORY NOTES
 
     On October 25, 1995, the Company entered into a loan and security agreement
comprised of a $500 line of credit, which expired on October 25, 1996 and a $250
term facility, which would have expired on October 15, 1998, bearing interest at
the prime rate plus 2% and prime rate plus 3%, respectively. On January 9, 1997,
the Company replaced the $500 line of credit and $250 term facility by entering
into a loan and security agreement comprised of a $2.0 million line of credit,
which expired on January 9, 1998, bearing interest at the prime rate (8.5%) plus
0.5%. The agreement is collateralized by the assets of the Company, contains
certain financial covenants and restricts the Company's ability to incur other
indebtedness and pay dividends. As of December 31, 1997, the balances
outstanding under the line of credit agreements was $243. The outstanding
balance under the term facility was $250 as of December 31, 1996 and this amount
was repaid in 1997. As of March 31, 1998, the Company had not yet renewed this
line of credit agreement.
 
(7) PREFERRED STOCK AND STOCKHOLDERS' EQUITY (DEFICIT)
 
  Preferred Stock
 
     As of December 31, 1997, there were 6,500 authorized shares of preferred
stock, none of which are designated or outstanding, with a $0.01 per share par
value.
 
  Stock Option and Purchase Plans
 
     In February 1996, the Company adopted the 1996 Equity Incentive Plan (the
1996 Plan), under which 1,000 shares of common stock were reserved for issuance.
The 1996 Plan became effective in April 1996 on the effective date of the
Company's initial public offering. The 1996 Plan provides for the grant of
options, stock bonuses and restricted stock purchase rights. The compensation
committee of the Board of Directors has the authority to set exercise dates (no
longer than 10 years from date of grant), payment terms and other provisions for
each grant. Options are subject to vesting as determined by the compensation
committee, generally over 48 months. Vesting and exercisability of certain
outstanding options and other stock awards under the 1996 Plan will accelerate
upon certain change of control transactions. In August 1997, an additional 750
shares of common stock were reserved for issuance under the Company's 1996 Plan.
 
     The Company's 1992 Stock Option Plan (the 1992 Plan) terminated at the
effective date of the Company's initial public offering, at which time the 1996
Plan became effective. As a result, no further options may be granted under the
1992 Plan. However, termination of the 1992 Plan does not affect outstanding
options, all of which remain outstanding until exercised or until they terminate
or expire. The terms of options granted under the 1992 Plan and the
administration of the 1992 Plan are substantially the same as the 1996 Plan,
except that vesting of options under the 1992 Plan does not accelerate upon an
acquisition.

     Certain outstanding options under the stock option plan granted to officers
are immediately exercisable but subject to repurchase by the Company at a rate
equivalent to the current vesting schedule of each option. During 1997, the
Company repurchased 75 shares. As of December 31, 1997 and 1996, 82 and 454
shares were subject to repurchase, respectively.
 
     The Company has recorded deferred compensation of $175 for the difference
between the grant price and the deemed fair value of the common stock underlying
the options granted in November and December 1995. This amount is being
amortized over the vesting period of the individual options, generally four
years.
 
     In February 1996, the Company adopted the 1996 Employee Stock Purchase Plan
(the Purchase Plan) and reserved a total of 1,000 shares of common stock for
issuance thereunder. The Purchase Plan became effective in April 1996, on the
effective date of the Company's initial public offering and permitted eligible

employees to acquire shares of the Company's common stock through payroll
deductions at a price equal to 85% of the lower of the fair market value at the
beginning or end of each six-month offering period. As of December 31, 1997, a
cumulative total of 159 shares had been issued under the Purchase Plan.
 
     In April 1997, the Company offered option holders under its stock option
plans the opportunity to have outstanding unvested options repriced to the then
current fair market value of the Company's common stock of $3.75 per share.
Employees electing to have options repriced were required to accept an extension
of their vesting schedule. The other terms of the options remained unchanged. On
April 28, 1997, the Company amended 852 options pursuant to this offer.
 
     The per share weighted-average fair value of stock options granted during
1997, 1996 and 1995 was $2.12, $4.26 and $0.40, respectively, on the date of
grant using the Black-Scholes option-pricing model with the following
assumptions: 1997 expected dividend yield 0%, risk-free interest rate of 6.32%,
expected volatility of 57% and expected life of 3.2 years; 1996 expected
dividend yield 0%, risk-free interest rate of 6.25%, expected volatility of 57%,
and expected life of 4 years; 1995 expected dividend yield 0%, risk-free
interest rate of 6.10%, expected volatility of 57% and expected life of 4 years.
 
     The per share weighted-average fair value of employees' stock purchase
rights under the Purchase Plan included in the pro forma amounts was estimated
using the Black-Scholes model with the following assumptions: 1997 dividend
yield of 0%, expected life of 6 months, expected volatility of 57% and risk-free
interest rate of 5.31%; 1996 expected dividend yield of 0%, expected life of 6
months, expected volatility of 57% and risk-free interest rate of 6.25%. The
weighted-average fair value of purchase rights granted in 1997 and 1996 was
$1.89 and $4.39, respectively.
 
     The Company uses the intrinsic value method in accounting for its
stock-based compensation plans. Accordingly, no compensation cost has been
recognized for these plans in the financial statements. Had the Company
determined compensation cost for its stock-based compensation plans under SFAS
No. 123, the Company's net loss would have been increased to the pro forma
amounts indicated below:

     Pro forma net income reflects only options granted in 1997, 1996 and 1995.
Therefore, the full impact of calculating compensation cost for stock options
under SFAS No. 123 is not reflected in the pro forma net loss amounts presented
above because compensation cost is reflected over the options' vesting period of
three to four years and compensation cost for options granted prior to January
1, 1995, is not considered.
 
  Warrants
 
     In conjunction with various financing arrangements in 1994 and 1995, the
Company issued warrants to purchase 28 shares of common stock at prices ranging
from $1.50 per share to $18.16 per share and 7 shares of Series B redeemable
preferred stock now exercisable for Common Stock in lieu of the Preferred Stock
at $2.24 per share. These warrants expire at various dates through 2004.

  Employee Benefit Plan
 
     The Company has a 401(k) plan that allows eligible employees to contribute
up to 20% of their compensation up to a statutory maximum amount. Employee
contributions and earnings thereon vest immediately. The Company may make
discretionary contributions to the 401(k) plan; none have been made to date.
 
  Legal Actions
 
     The Company is engaged in certain legal actions arising in the ordinary
course of business. The Company believes that it has adequate legal defenses and
that ultimate outcome of these actions will not have a material effect on the
Company's financial position and results of operation.
 
(9) INTERNATIONAL SALES AND MAJOR CUSTOMERS
 
     International sales accounted for 28%, 24% and 14% of the Company's total

the technical language conventional to Products and similar computer products in

customers or to the trade with respect to the specifications, features or
capabilities of Products that are inconsistent with the literature distributed
by Worldtalk;

            (h) Compliance with Law. SDTI will comply with all applicable
international, national, state, regional and local laws and regulations in
performing its duties hereunder and in any of its dealings with respect to
Products.

            (i) Compliance with U.S. Export Laws. SDTI acknowledges that all
Products including documentation and other technical data are subject to export
controls imposed by the U.S. Export Administration Act of 1979, as amended (the

            (j) Costs and Expenses. Except as expressly provided herein or

incurred in the performance of SDTI's obligations under this Agreement.

        4.  ORDER PROCEDURE.

            (a) Worldtalk Acceptance. All orders for Products by SDTI shall be
subject to acceptance in writing by Worldtalk at its principal place of business
and shall not be binding until the earlier of such acceptance or shipment, and,
in the case of acceptance by shipment, only as to the portion of the order
actually shipped.

            (b) Controlling Terms. The terms and conditions of this Agreement
and of the applicable Worldtalk invoice or confirmation will apply to each order
accepted or shipped by Worldtalk hereunder. The provisions of SDTI's form of
purchase order or other business forms will not apply to any order
notwithstanding Worldtalk's acknowledgment or acceptance of such order.

            (c) Cancellation. Worldtalk reserves the right to cancel any orders
placed by SDTI and accepted by Worldtalk as set forth above, or to refuse or
delay shipment thereof, if SDTI fails to make any payment as provided in this
Agreement or under the terms of payment set forth in any invoice or otherwise
agreed to by Worldtalk and SDTI. Worldtalk also reserves the right to
discontinue the manufacture or distribution of all versions of the Products that
have been superseded by subsequent versions with equal or greater functionality.
Worldtalk will give SDTI at least 120 days notice before ceasing to make
available to SDTI for distribution hereunder a Major Release (as defined in
Exhibit A), it being understood that Worldtalk will continue to provide
maintenance for such Major Release as provided in Section 9(f). No such
cancellation, refusal or delay will apply to any Product subject to an
outstanding purchase order with a firm delivery schedule or be deemed a
termination (unless Worldtalk so advises SDTI) or breach of this Agreement by
Worldtalk.


                                       5

        5.  DEMONSTRATIONS, BENCHMARKS, AND EVALUATIONS.

            (a) Demonstrations. SDTI will be responsible for demonstrations and
benchmarks of Products to, and evaluations by, its prospective customers.
Assistance by Worldtalk in any demonstrations or benchmarks will be at
Worldtalk's discretion and at Worldtalk's standard rates for its personnel.

            (b) Evaluation Copies. Worldtalk will provide SDTI, at no charge,
with a reasonable number of copies of Products for use by SDTI solely for the
purpose of conducting demonstrations and benchmarks by SDTI personnel without
charge. Worldtalk will also provide SDTI and each Subdistributor up to five (5)
evaluation copies for internal use only. All demonstration and evaluation copies
will be prominently marked "NOT FOR RESALE". Worldtalk at its discretion may
include with any copies to be used for demonstration a distinct shrinkwrap
license agreement that further limits Worldtalk's liability. Any use of the
Products by SDTI or any SDTI personnel or customer will be subject to the terms
and conditions of the Worldtalk license agreement accompanying such Product,
provided that the use of any such copies provided to any prospective customer
will be limited to no more than 30 days. Upon Worldtalk's reasonable request,
SDTI shall provide Worldtalk with a copy of each executed evaluation agreement.

        6.  PRICES, LICENSE FEES AND PAYMENT.

            (a) Prices and License Fees to SDTI. During the term of this
Agreement, SDTI will pay Worldtalk the fees set forth on Exhibit D for the
Products purchased by SDTI under this Agreement. Worldtalk shall inform SDTI as
to current prices and license fees to SDTI for Products. Worldtalk may change
its prices and license fees to SDTI from time to time upon at least ninety (90)
days' prior written notice. Prices for the Products shall not increase more than
[ ** ] per year; provided however that Worldtalk reserves the right to set
pricing for Major Upgrades as they occur.

            (b) Price and License Fee Increase. In the event Worldtalk increases
the price or license fees to SDTI for any Product, the increase shall apply to:
any order received by Worldtalk after the effective date of the increase; and
any order or portion thereof to be shipped after the effective date of the
increase regardless of the date the order was received; provided, however, that
any order or portion thereof transmitted by SDTI prior to Worldtalk's
announcement of the increase and affected thereby, may be canceled without
penalty by SDTI by written notice to Worldtalk within ten (10) days of such
announcement.

            (c) Price and License Fee Decrease. In the event that Worldtalk
decreases the price or license fees to SDTI for any Product, the decrease shall
apply to all units of such product in SDTI's inventory that are in an unopened
condition as of the effective date of the decrease, and that had been shipped to
SDTI no more than [ ** ] prior to such effective date. For each unit of product
as to which this section applies, SDTI will receive a credit against the price
or license fee of a subsequent unit purchased from Worldtalk within [ ** ] of
the effective date of the price or license fee decrease.


                                       6
<PAGE>   7

            (d) Taxes, Tariffs, Fees. Worldtalk's prices and license fees do not
include any national, state or local sales, use, value added or other taxes,
customs duties, or similar tariffs and fees which Worldtalk may be required to
pay or collect upon the delivery of Products or upon collection of the prices
and license fees or otherwise. Should any tax or levy be made, SDTI agrees to
pay such tax or levy and indemnify Worldtalk for any claim for such tax or levy
demanded. SDTI represents and warrants to Worldtalk that all Products acquired
hereunder are for redistribution in the ordinary course of SDTI's business, and
SDTI agrees to provide Worldtalk with appropriate resale certificate numbers and
other documentation satisfactory to the applicable taxing authorities to
substantiate any claim of exemption from any such taxes or fees. SDTI will pay
any withholding taxes required by applicable law. SDTI will supply Worldtalk
with evidence of such payment of withholding tax, in a form acceptable to
Worldtalk to meet the requirements for claiming foreign tax credits on
Worldtalk's federal income tax return.

            (e) Payment Terms. All payments shall be made in United States
dollars, free of any currency control or other restrictions to Worldtalk at the
address designated by Worldtalk. Except as otherwise stated, fees are due within
30 days following the date of invoice (with respect to Product purchases) or
accrual (with respect to maintenance and support fees). Maintenance and support
fees accrue upon accrual of the underlying fees to SDTI. Interest shall accrue
on any delinquent amounts owed by SDTI for Products at the lesser of twelve
percent (12%) per annum or the maximum rate permitted by applicable usury law.

            (f) SDTI Pricing. Although Worldtalk may publish suggested wholesale
or retail prices, these are suggestions only and SDTI will be entirely free to
determine the actual prices and license fees at which Products will be sold or
licensed to its customers.

        7.  SHIPMENT, RISK OF LOSS AND DELIVERY.

            (a) Shipment. All Products will be shipped by Worldtalk Ex-Works
Factory, Worldtalk's point of shipment. Shipments will be made to SDTI's
identified location, subject to approval in writing by Worldtalk in advance of
shipment. Unless specified in SDTI's order, Worldtalk will select the mode of
shipment and the carrier. SDTI will be responsible for and pay all shipping,
freight and insurance charges, which charges Worldtalk may require SDTI to pay
in advance. Worldtalk will deliver the Products to SDTI with all packaging
intact and will pay all charges for packaging such Products.

            (b) Title and Risk of Loss. Title, except to the extent Products
contain or consist of software, and all risk of loss of or damage to Products
will pass to SDTI upon delivery to SDTI.

            (c) Partial Delivery. Unless SDTI clearly advises Worldtalk to the
contrary in writing, Worldtalk may make partial shipments on account of SDTI's
orders, to be separately invoiced and paid for when due. Delay in delivery of
any installment shall not relieve SDTI of its obligation to accept the remaining
deliveries.

            (d) Delivery Schedule; Delays. Worldtalk will use reasonable efforts
to meet SDTI's requested delivery schedules for Products, but Worldtalk reserves
the right to refuse, 


                                       7
<PAGE>   8

cancel or delay shipment to SDTI when SDTI's credit is impaired, or SDTI is
delinquent in payments. Should orders for Products exceed Worldtalk's available
inventory, Worldtalk will allocate its available inventory and make deliveries
on a basis Worldtalk deems equitable, in its sole discretion, and without
liability to SDTI on account of the method of allocation chosen or its
implementation. In any event, Worldtalk will not be liable for any damages,
direct, consequential, special or otherwise, to SDTI or to any other person for
failure to deliver or for any delay or error in delivery of Products for any
reason whatsoever.

        8.  REPORTS AND AUDITS.

            (a) SDTI will maintain complete records, during and for 1 year after
the termination or expiration of this Agreement, regarding the distribution of
Products. Worldtalk will maintain complete records, during and for 1 year after
the termination or expiration of this Agreement, regarding the pricing of
Products distributed to third parties. Each party may audit the records of the
other party once per year and at the requesting party's expense to verify
compliance with the foregoing and the other terms and conditions of this
Agreement. SDTI will use its best efforts to require any Subdistributors of the
Products to maintain records of the same nature and for the same period required
of SDTI under this Section 8.

            (b) SDTI will provide a quarterly customer activity report showing
number of Products sold and Products returned for refund or exchange. SDTI will
use reasonable efforts to track the reasons for return of Products and
communicate such reasons to Worldtalk in such report.

        9.  MAINTENANCE, SUPPORT AND TRAINING.

            (a) Upgrade for SecurID and Year 2000 Compliance. [ ** ]

            (b) First, Second and Third Line Support. SDTI will provide first
and second line support for the Products. Worldtalk will provide third line
support as specified in Exhibit F. The parties agree to mutually establish a
process to provide expedited resolution to problems including access to
Worldtalk WorldSecure support engineers. Each party will assign a contact person
with respect to support issues. Worldtalk will include a limited warranty with
each Product as specified in Exhibit H. SDTI will be responsible vis a vis all
customer purchasing Products through SDTI for all warranty returns and claims
for the Products (notwithstanding that Worldtalk is specified therein as making
such warranty). Worldtalk will replace without charge to SDTI any Product
returned by SDTI that is specified to be a warranty exchange and verified by
Worldtalk to be in breach of warranty. In the event that as a result of a
warranty claim in accordance with such warranty verified by Worldtalk to be in
breach of warranty SDTI is required to refund amounts to any customer of SDTI,
SDTI will report such refund in the quarterly report specified in Section 8(b)
above, and Worldtalk will credit the amount paid by SDTI to Worldtalk for such
Product toward future orders for Products. SDTI will use at least the same
efforts to support the Products as it provides for its own products.


                                       8
<PAGE>   9
            (c) Support. Worldtalk will make available to SDTI a reasonable
number copies of Product solely for the purpose of providing support for the
Products as described in Exhibit F during the term of this Agreement and in
accordance with the provisions of this Section 9. Worldtalk will promptly
provide upgraded versions of the Product to SDTI for purposes of this Section 9
upon commercial release.

            (d) Training. Worldtalk will use its best efforts to keep the SDTI
SE, sales and support staffs well-trained to effectively represent the Products
throughout the term of this Agreement, including training for up to 10 SDTI
internal support and sales support engineers at a time and including "train the
trainer" courses for the SDTI channel as reasonably agreed between the parties
at mutually agreed upon times, as indicated in Exhibit I. All Worldtalk training
described on Exhibit I will be provided by Worldtalk personnel without charge to
SDTI except as described below. Any additional training requested by SDTI will
be at SDTI's expense. Worldtalk will provide training materials at no charge to
SDTI for the initial training session described in Exhibit I. SDTI will be
responsible for all travel and living expenses for SDTI personnel attending
training. SDTI will ensure that a reasonable number of its technical and/or
sales personnel attend all such training, including (without limiting the
obligation to provide a reasonable number of such individuals) at least two
individuals for each Product for which SDTI has the right to distribute under
this Agreement. The amount of training time will be reasonable and appropriate
in Worldtalk's judgment.

            (e) Sales Materials. Worldtalk will make available at no charge to
SDTI up to 2,000 copies of its sales and marketing kits for the Products.
Worldtalk will make available at SDTI's expense updated sales information as new
versions and options to the specified Products are released by Worldtalk.

            (f) Maintenance. Worldtalk agrees to provide maintenance to SDTI in
the form of Major Releases and Minor Releases as set forth in Exhibit A in
consideration for the fees set forth in Exhibit D. Worldtalk agrees that for a
period of one year following the discontinuation of the last version of a Major
Release (as defined in Exhibit A) of a Product, that it will continue to provide
maintenance to SDTI for such version of such Product under the terms and
conditions of this Agreement. Worldtalk's maintenance and support obligations
with respect to the Products distributed by SDTI hereunder will be solely to
SDTI, and Worldtalk will have no obligation to any customer of SDTI or any other
party.

            (g) Source Code Escrow. Upon execution of this Agreement, the
parties will execute the escrow agreement with Data Securities International
attached as Exhibit J. All fees and expenses of such escrow agent will be paid
by SDTI. Within ninety (90) days after the execution of this Agreement,
Worldtalk will place into the escrow account copies of the complete source code
for the Products (the "Source Materials"). Worldtalk will also deposit into the
escrow account the complete source code of any and all error corrections,
updates, enhancements, Major Releases, Minor Releases, and any other changes to
the Source Materials provided by Worldtalk to SDTI in accordance with this
Agreement, within ninety (90) days after


                                       9
<PAGE>   10
Worldtalk provides any of the foregoing to SDTI hereunder. Worldtalk agrees
that, subject to the terms and conditions of the escrow agreement, SDTI will
have the right to obtain the Source Materials from escrow following the
occurrence of Worldtalk's material failure to support the Products in accordance
with Section 9(b) following written notice thereof from SDTI and a thirty-five
(35) day period to cure. Worldtalk hereby grants to SDTI a nonexclusive,
nontransferable royalty free license to use, copy, modify, and have modified,
the Source Materials in SDTI's possession following the release of the Source
Materials to SDTI pursuant to this Section 9(g) for the sole purpose of
maintaining the Products by SDTI in accordance with the terms of Section 9(b).
Such Source Materials as may be released to SDTI will be kept by SDTI in strict
confidence as Confidential Information of Worldtalk in accordance with the terms
of Section 10 below. The fees of the escrow agent will be paid by SDTI.

        10.  CONFIDENTIALITY.

            (a) Obligations. Each party agrees that it will not disclose to any
third party or use any technical or other proprietary and confidential
information disclosed to it by the other (collectively, "Confidential
Information") except as expressly permitted in this Agreement and that it will
take all reasonable measures to maintain the confidentiality of all Confidential
Information in its possession or control, which will in no event be less than
the measures it uses to maintain the confidentiality of its own information of
similar importance.

            (b) Nondisclosure of Terms of Agreement. Each party agrees that it
will not, without the prior written consent of the other party, disclose the
terms, or conditions of this Agreement except as required by applicable law or
regulation and then only after the party required to make such disclosure has
used reasonable efforts to maintain the confidentiality of all [ ** ] financial
and technical terms included within the scope of Confidential Information,
including without limitation the filing of a request for confidential treatment
with respect to such Confidential Information with the applicable government
authority and upon notice to the other party.

            (c) Exceptions. "Confidential Information" will not include
information that:

            (i) is in or enters the public domain without breach of this
      Agreement;

            (ii) a party lawfully receives from a third party without
      restriction on disclosure and without breach of a nondisclosure
      obligation; or

            (iii) a party develops independently, which it can prove with
      written evidence.

exclusive right at its discretion to assert claims against third parties for

or settle at Worldtalk's own expense, any claim, action or other proceeding
brought against SDTI to the extent that it is based on a claim that the use or

or that the Products incorporate any misappropriated trade secrets.

                    (B) Worldtalk will pay any and all costs, damages, and

has sole control of its defense and settlement; and (3) SDTI provides Worldtalk
with reasonable assistance in its defense and settlement at Worldtalk's expense.

                (ii) Injunctions. If SDTI's use of any Products under the terms

then Worldtalk shall, at its sole option and expense, either: (A) procure for
SDTI the right to continue using such Products under the terms of this
Agreement; or (B) replace or modify such Products so that they are noninfringing
and substantially equivalent in function to the enjoined Products; or (C) if
options (A) and (B) above cannot be accomplished despite the reasonable efforts
of Worldtalk, then Worldtalk may both terminate SDTI's rights and Worldtalk's
obligations under this Agreement with respect to such Products, and shall refund
to SDTI the license fees paid by SDTI to Worldtalk for such Products as SDTI is
required to refund to its customers.

                (iii) Sole Remedy. THE FOREGOING ARE WORLDTALK'S SOLE AND
EXCLUSIVE OBLIGATIONS, AND SDTI'S SOLE AND EXCLUSIVE REMEDIES, WITH RESPECT TO
INFRINGEMENT OR MISAPPROPRIATION OF INTELLECTUAL PROPERTY RIGHTS.

                (iv) Exclusions. Worldtalk will have no obligations under this
Section 14(b) with respect to infringement or misappropriation to the extent
arising from (A) modifications made by SDTI, (B) Product specifications

not provided by Worldtalk.

        14. LIMITATIONS OF LIABILITY.

            (b) Exclusion of Damages. IN NO EVENT WILL WORLDTALK BE LIABLE TO
SDTI, SUBDISTRIBUTORS OR ANY THIRD PARTY FOR ANY SPECIAL, INCIDENTAL, OR
CONSEQUENTIAL DAMAGES, WHETHER BASED ON BREACH OF CONTRACT, TORT (INCLUDING
NEGLIGENCE), PRODUCT LIABILITY, OR OTHERWISE, AND WHETHER OR NOT WORLDTALK HAS
BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGE. IN NO EVENT SHALL SDTI BE LIABLE
TO WORLDTALK FOR SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES.

            (c) Failure of Essential Purpose. The parties have agreed that the
limitations specified in this Section 15 will survive and apply even if any
limited remedy specified in this Agreement is found to have failed of its
essential purpose.

        15. TERM AND TERMINATION.

            (a) Term. The term of this Agreement will begin on the Effective
Date and will continue for three (3) years after the date for first commercial

                  (iii) the other party becomes the subject of an involuntary

        will continue to provide maintenance and support as provided in Section
        10 in accordance with the terms of this Agreement so long as Worldtalk
        is providing such maintenance and support to its customers generally)
        and continue to use copies of the Products, subject to continued payment
        by SDTI of the maintenance and support fees provided in Exhibit D, to
        the extent needed to provide such services, pursuant to a limited
        license agreement to be entered between Worldtalk and SDTI promptly
        following such termination or expiration.

            (d) No Damages for Termination. NEITHER PARTY WILL BE LIABLE TO THE
OTHER FOR DAMAGES OF ANY KIND, INCLUDING INCIDENTAL OR CONSEQUENTIAL DAMAGES, ON
ACCOUNT OF THE TERMINATION OR EXPIRATION OF THIS AGREEMENT IN ACCORDANCE WITH

<PAGE>   15

its terms for reimbursement or damages for the loss of goodwill, prospective

                                    PRODUCTS

WorldSecure Server Ver. 2.0
WorldSecure Client Ver. 2.0
NetTalk Ver. 4.3

Additional upgraded versions will be made available to SDTI under the terms of
this Agreement upon commercial release by Worldtalk.

SDTI will initially use WorldSecure administration to manage Worldtalk
WorldSecure components. At a later point in time, SDTI may desire to integrate
WorldSecure Server and Client administration with ACE/Server administration.

SDTI will initially use WorldSecure installation processes. In the future, SDTI
may wish to incorporate WorldSecure Products with other SDTI products and
provide a common installation and distribution. Examples may include WorldSecure
Server with ACE/Server, WorldSecure Client with SecurPC or SoftID, WorldSecure
Client distributed from ACE/Server.

Worldtalk will discuss with SDTI in good faith the foregoing changes proposed by
SDTI, which may be made at Worldtalk's sole discretion.

Worldtalk will make available to SDTI Major Releases and Minor Releases of the
Products as it makes such Major Releases and Minor Releases available to it
customers generally, under the terms and conditions of this Agreement as
follows: Worldtalk will make Minor Releases available to SDTI at no cost for
distribution solely to customers of SDTI for which SDTI has paid Worldtalk the
applicable maintenance fee hereunder. Minor Releases may not be distributed to
customers of SDTI for which SDTI has not paid such fees for the applicable time
period. Worldtalk will make Major Releases available to SDTI at the charge that
Worldtalk makes such Major Release available to its own customers as indicated
on the then current price list less a [ ** ] discount. Major Releases priced as
upgrades (i.e., a discount off of full price) may be distributed only to
customers of SDTI who have licensed the applicable prior version from SDTI. For
example, if the Worldtalk list price for a new Product version 3.0 is [ ** ] and
the price Worldtalk charges for version 3.0 to its customers who have licensed
version 2.0 is [ ** ] SDTI will pay Worldtalk [ ** ] for a new Product and [ **
] for such upgrade, provided that SDTI confirms that such version 3.0 will be
distributed only to a customer that has licensed version 2.0. SDTI will use
reasonable efforts to verify that a customer is in fact a licensee of a prior
version before distributing a version priced as an upgrade. As used herein,
"Minor Release" means an enhancement, improvement or upgrade to the Product
distributed by Worldtalk generally to its customers who have paid for periodic
maintenance which does not materially change the functionality of such Product,
and a "Major Release" means a significant modification or improvement to the
Product considered by Worldtalk to be a new product. In general, a Major Release
will be given a new product number by Worldtalk, 


<PAGE>   18

although it may be labeled as a new version adding such modification or
improvement to an existing product.

Additional Worldtalk Products may be added under this Agreement in the future by
mutual agreement. Terms and conditions will be negotiated in good faith.

                                     PRICING

        Nonrefundable Prepaid Fees. SDTI will pay Worldtalk a one-time prepaid,
nonrefundable license fee of $3,000,000 on October 1st or when all Products are
available for shipment, whichever is later, to be applied toward fees due under
this Agreement to Worldtalk during the term of this Agreement.

        SDTI may at its option elect to pay an additional one-time prepaid,
nonrefundable license fee of [ ** ] ("Second Year Prepayment") to Worldtalk on
or before the first anniversary of the date of this Agreement to maintain the
Discount at [ ** ] for the one year period beginning on the first anniversary of
FCS, which Second Year Prepayment will be applied toward fees due under this
Agreement to Worldtalk during the term of this Agreement. If SDTI fails to make
such Second Year Prepayment, the Discount will be [ ** ] for such period and
through the remaining term of the Agreement.

        If SDTI has paid the Second Year Prepayment to Worldtalk in accordance
with the foregoing sentence, SDTI may at its option elect to pay an additional
one-time prepaid, nonrefundable license fee of [ ** ] ("Third Year Prepayment")
to Worldtalk on or before the second anniversary of the date of this Agreement
to maintain the Discount at [ ** ] for the one year period beginning on the
second anniversary of FCS, which Third Year Prepayment will be applied toward
fees due under this Agreement to Worldtalk during the term of this Agreement. If
SDTI does not make such Third Year Prepayment, the Discount will be [ ** ]
through the remaining term of the Agreement.

        Discount. SDTI will pay Worldtalk a license fee equal to Worldtalk's
then-current List Price for each Product less the Discount. For purposes of this
Agreement, "List Price" means the price per unit set forth on Worldtalk's
then-current published U.S. price list; and "Discount" means initially [ ** ] as
adjusted in accordance with the provisions specified under the heading
"Nonrefundable Prepaid Fees" above. The prepaid royalty amount will be applied
against [ ** ] of the purchase price of any Product purchased under this
Agreement until such prepaid royalty has been recouped in full. Worldtalk's
current price list is attached hereto as Exhibit D-1.

        Most-Favored Customer Pricing. Notwithstanding the foregoing, during the
term of this Agreement, Worldtalk will extend to SDTI discounts equivalent to
any more favorable discount off of List Price afforded to other distributors or
resellers for similar types and quantities of Products under terms and
conditions similar to those requested by SDTI in accordance with this Agreement.

        Maintenance Fees. SDTI will pay Worldtalk a maintenance fee equal to
Worldtalk's standard maintenance fee ([ ** ] of the List Price) less a [ ** ]
discount for the first year of a maintenance contract entered into upon purchase
of the Product. SDTI will pay Worldtalk an amount equal to Worldtalk's standard
maintenance fee less a [ ** ] discount for 

<PAGE>   22

each annual renewal of such contract after the initial year. Such fees will be
payable within 30 days following the calendar quarter in which such contract is
entered into.

        Customer Support Fees. In addition, in consideration for providing third
line support under this Agreement, SDTI will pay Worldtalk [ ** ] of all
maintenance and support fees collected by SDTI for the Products. Notwithstanding
the foregoing, if SDTI has paid to Worltalk less than [ ** ] for such
maintenance and support fees during the 12 month period ending on any
anniversary following FCS, SDTI will pay to Worldtalk the sum calculated by
subtracting actual fees so paid from [ ** ] upon each such anniversary (so that
during any year SDTI will pay Worldtalk at least [ ** ] for such maintenance and
support fees).

                                    UPGRADES


Worldtalk will use its best efforts to integrate SecurID identification and
authentication agents in the WorldSecure Server, WorldSecure Client and NetTalk
as an upgrade to such Products in the ordinary course of development on or
before January 1, 1998. The intent of the upgrade is to require SecurID
authentication for the WorldSecure Server, WorldSecure Client and NetTalk
Products to access the server. The upgraded WorldSecure Client would require
users to SecurID authenticate to send secure messages and to decrypt secure
messages. SecurID authentication is intended to be configurable within the
WorldSecure Server, Client and NetTalk.

Worldtalk will warrant that the Products distributed by Worldtalk to SDTI under
this Agreement will be Year 2000 Compliant, as defined below, with respect to
Products delivered by Worldtalk to SDTI, on a best efforts basis on or before
January 1, 1998 but no later than March 31, 1998. Upon release by Worldtalk of
the upgrades of the Products that make such Products Year 2000 Compliant,
Worldtalk will make available to SDTI without charge an upgrade for distribution
by SDTI to its customers for which SDTI has paid for maintenance to allow the
Products distributed under this Agreement by SDTI to be Year 2000 Compliant and
will warrant that the Products delivered by Worldtalk to SDTI will be Year 2000
Compliant.

For purposes hereof, "Year 2000 Compliant" means that the Products, when used in
accordance with their applicable documentation and the hardware and operating
system software with which they are designed to function, will correctly manage,
calculate, compare and sequence data involving dates between January 1, 1970 and
December 31, 2036, inclusive, including but not limited to single century
formulas and multi-century formulas, provided that all products not supplied as
part of the Products which exchange date data with the Products do so properly
and accurately and in a form compatible with the Products. Worldtalk assumes no
liability of any kind with respect to any interruption of service, impairment of
function or erroneous results in the operation of the Products directly or
indirectly caused by any date processing of any other software, by the failure
of any hardware or other software or by failure to supply date data to the
Products in a form and format compatible with the Products.

SDTI will provide such assistance as Worldtalk reasonably requires to enable
Worldtalk to effect such upgrades.

PROBLEM REPORTING AND RESOLUTION

SDTI's Responsibilities

SDTI is responsible for providing technical resources with the ability to
provide problem management and technical resolution activities directly to their
customers. SDTI technical activity responsibilities during an escalation
include:

I. Setting SDTI's customer expectations, communication with its
customers, and customer account management. SDTI retains sole responsibility for
its customers throughout the problem escalation and resolution process.

II. Ensuring a customer's problem is not generated by an unsupported system
configuration or third party cause.


<PAGE>   28

III. Setting the initial level of severity based on the impact to its customers.

IV. Duplicating the problem to the best of its ability for isolation and testing
purposes.

V. Determining and documenting the operational steps needed to reproduce the
problem.

VI. Isolating the cause of the problem: A. Determining the product and module,
if possible; B. Determining what actions are causing the problem.

VII. Resolving the problem:
A. Providing a workaround, where possible, to alleviate the impact on a
customer's operations. Another solution may be provided at a later time.

When SDTI must escalate a problem to Worldtalk, SDTI is responsible for:

I. Escalating only problems that have been determined to be, or are
highly probable to be, the result of a design or implementation defect in the
Product that cannot be resolved by SDTI.

II. Providing clear, accurate, and complete problem statements with symptoms and
environment information which includes but is not limited to:
A. Date customer initially reported problem;
B. Concise customer impact statement;
C. Vendor or third party information if appropriate;
D. Configuration data;
E. Pointers to supporting information on frequency, error logs, dump
   files;
F. Steps taken to correct the problem; G. Current status of problem.

III. Ensuring highly qualified resources are available to assist Worldtalk.
These resources will be involved in:
A. On-site information gathering;
B. Testing solutions at the customer site;
C. Troubleshooting the problem;
D. Assisting with any phase of solution development when necessary;
E. Duplicating the problem, where possible.

IV. Ensuring that any workaround or final resolution provided is usable and
acceptable in the customer's environment.


<PAGE>   29

V. Delivery of all Worldtalk lab tested solutions to the customer in an
expeditious fashion and verifying that they work in the customer's environment.

VI. Promptly reporting any problems with the solutions to Worldtalk.

Worldtalk's Responsibilities

Worldtalk's responsibilities include:

I. Ensuring timely resolution of problems properly escalated to
Worldtalk.

II. Isolation and management of all escalated problems that are "undefined," or
can be labeled "other" (i.e., interoperability or multivendor).

III. Defining the communications, via the Internet, between Worldtalk and SDTI
on all problems.

IV. Ensuring Worldtalk resources are available to address problems at all levels
of Severity (see below).

V. Further isolating the detailed cause of the escalated problem.

VI. Providing a work-around until a permanent solution is available, as
appropriate.

VII. Creating a technical solution where appropriate.

VIII. Properly testing the solution:
A. Ensuring that the solution is fully tested and that the solution does not
create other problems. B. Properly testing reproducible problems to ensure that
the escalated remedial problems have been addressed.

IX. Ensuring the solution is documented and considered for incorporation into
future versions of the Products.

Problem Resolution

For Severity 1 problems, the objective is to get the customer's operation back
on line within twenty-four (24) hours and to downgrade the problem accordingly.
Severity 1 problems will not be considered closed until one of the following
activities has been completed:


<PAGE>   30

1. A code change in the form of a "patch," a formal engineering
change order, a new image, or new revision that corrects the problem without
causing additional problems has been delivered to the customer, successfully
installed and is working.

2. A work-around is delivered to and accepted by the customer as a final
solution.

3. To correct the problem within a named specific update of the
product. This applies when the problem cannot be economically or feasibly
solved, and requires a redesign of the product or rewrite of the segment of code
or image.

4. A policy or position statement is issued by Worldtalk that explains why
Worldtalk does not intend to take any further action.

Communications

The primary method of communications between Worldtalk and SDTI shall be via the
Internet. Worldtalk will provide support by telephone as reasonably necessary.
Upon execution of this agreement, Worldtalk and SDTI shall prepare a
communications document detailing the methodology and specific addresses
necessary to implement the problem reporting and resolution process.

REMEDIAL PROBLEM DEFINITION

Severity Definitions

The escalation process incorporated in this Exhibit F categorizes problems into
three levels of severity. This section contains definitions, response
requirements and implementation guidelines for SDTI and Worldtalk.

The severity levels set by SDTI and as agreed by Worldtalk must reflect the
total situation from both the technical and customer impact aspects.

These levels of severity drive the goals for both SDTI and Worldtalk.

1. Severity 1

"Severity 1" problems (a) prevent installation of the Product, (b) cause the
Product, the SDTI product in which such Product is incorporated or the
customer's operating system to fail completely, (c) require constant restarting
of the Product, the SDTI product in which such Product is incorporated or the
customer's operating system, (d) result in irretrievable corruption or loss of
data or (e) result in severe customer dissatisfaction. With Severity 1 problems,
there is no known work-around or solution to the problem. The customer is unable
to use the Product.


<PAGE>   31

When working a "Severity 1" problem, the goal is to drive its level of severity
to "2" so that usefulness of the system is regained by the customer.

2. Severity 2

"Severity 2" problems prevent the use of a documented function of the Product,
preventing or inhibiting the Product from accomplishing the task for which it
was designed. There is no known work-around to such problem and SDTI's
customer's use of the Product is severely restricted.

Efforts to isolate, diagnose, and effect a work-around or repair to a Severity 2
problem may be discontinuous. A work-around should be provided within two (2)
business days. Worldtalk will work with SDTI until both Worldtalk and SDTI agree
that the call should be closed. A permanent correction should be incorporated
into the next update of the Product. Within ten (10) calendar days of
Worldtalk's receipt of an error notification, Worldtalk will provide a plan for
fixing the error.

3. Severity 3

"Severity 3" will be assigned to (a) general usage questions, (b)
recommendations for Software enhancements or modifications and (c) calls that
are passed on to Worldtalk for informational purposes. The impact on the
Customer is non-critical.

If SDTI's sole reason for escalating a "Severity 3" call is to submit a draft
symptom/resolution for consideration by Worldtalk then Worldtalk will
acknowledge receipt and respond accordingly with recommendations.

Problem Response Criteria

Worldtalk shall acknowledge receipt of SDTI's problem report. Subject to the
coverage hours specified herein, on receipt of a problem from SDTI, Worldtalk
will respond as follows:

1. Severity 1: Respond within one (1) working hour of receipt;

2. Severity 2: Reasonable efforts to respond within four (4) business hours, but
not later than one (1) business day of receipt;

3. Severity 3: Respond within five (5) working days of receipt.

Coverage Hours

Support will be provided by Worldtalk to SDTI on a five (5) day by nine (9) hour
basis. Call hours are Monday through Friday 9:00 a.m. to 6:00 p.m. Pacific Time,
excluding locally observed holidays.


<PAGE>   32

Worldtalk will make support available to SDTI beginning January 1, 1998 at all
times not specified above, for which SDTI will pay Worldtalk [**] per hour
(other than the hours of 6:00 a.m. to 9:00 a.m. Pacific Time on nonholiday
weekdays, when such additional support will be provided without additional
charge), except that where a Severity 1 problem cannot be resolved with a
workaround and requires a code fix by Worldtalk, SDTI will not be billed for
off-hours charges. Worldtalk and SDTI will mutually agree upon a reasonable
procedure for accessing such support, it being understood that Worldtalk may not
be able to respond within the timeframes specified above for Severity 1 errors
during off-hours.

On-Site Support

Either Worldtalk or SDTI may provide on-site support to address Severity 1 level
problems. If a Severity 1 problem occurs and SDTI desires to provide on-site
support itself, it may contact Worldtalk. Worldtalk may at its discretion
confirm in writing that SDTI may provide its own on-site support, in which case
Worldtalk will reimburse SDTI for expenses reasonably incurred by SDTI in
providing such support to the extent the problem requires a code fix by
Worldtalk under this Agreement and no workaround exists. Worldtalk will not be
responsible for reimbursing SDTI if SDTI has not contacted and received written
confirmation from Worldtalk for SDTI to provide its own on-site support. If upon
contact by SDTI Worldtalk in its discretion determines to provide on-site
support itself, Worldtalk will do so at its expense, provided that if the
problem is not a Severity 1 problem for which Worldtalk is obligated to provide
a code fix under this Agreement or if a workaround existed, SDTI will reimburse
Worldtalk for expenses reasonably incurred in providing such support.

                                    MARKETING

SDTI will advertise Products in the Territory in accordance with this Agreement,
provided that SDTI will not use advertisements for the Products that have not
been approved in writing by Worldtalk. SDTI will at its expense: (i) attend, and
promote Products in, such trade shows, conventions and exhibits as Worldtalk
reasonably requests; (ii) attend any sales meetings held by Worldtalk to which
Worldtalk invites SDTI with reasonable notice; and (iii) notify Worldtalk of
SDTI's sales meetings and provide Worldtalk personnel adequate opportunity to
provide sales and promotion information regarding Products in such meetings.
SDTI and Worldtalk also contemplate conducting joint seminars with respect to
the Products.

                           PREFERRED ESCROW AGREEMENT

                      Account Number ______________________


This Agreement is effective September __, 1997 among Data Securities
International, Inc. ("DSI"), Worldtalk Communications Corporation, a Delaware
corporation ("Depositor") and Security Dynamics Technologies, Inc., a Delaware
corporation ("Preferred Beneficiary"), who collectively may be referred to in
this Agreement as "the parties."

A. Depositor and Preferred Beneficiary have entered or will enter into a license
agreement, development agreement, and/or other agreement regarding certain
proprietary technology of Depositor (referred to in this Agreement as "the
license agreement").

B. Depositor desires to avoid disclosure of its proprietary technology except
under certain limited circumstances.

C. The availability of the proprietary technology of Depositor is critical to
Preferred Beneficiary in the conduct of its business and, therefore, Preferred
Beneficiary needs access to the proprietary technology under certain limited
circumstances.

D. Depositor and Preferred Beneficiary desire to establish an escrow with DSI to
provide for the retention, administration and controlled access of the
proprietary technology materials of Depositor.

E. The parties desire this Agreement to be supplementary to the license
agreement pursuant to 11 United States [Bankruptcy] Code, Section 365(n).


ARTICLE 1  --  DEPOSITS

1.1 Obligation to Make Deposit. Upon the signing of this Agreement by the
parties, Depositor shall deliver to DSI the proprietary information and other
materials ("deposit materials") required to be deposited by the license
agreement.

1.2 Identification of Tangible Media. Prior to the delivery of the deposit
materials to DSI, Depositor shall conspicuously label for identification each
document, magnetic tape, disk, or other tangible media upon which the deposit
materials are written or stored. Additionally, Depositor shall complete Exhibit
A to this Agreement by listing each such tangible media by the item label
description, the type of media and the quantity. The 

<PAGE>   51

Exhibit A must be signed by Depositor and delivered to DSI with the deposit
materials. Unless and until Depositor makes the initial deposit with DSI, DSI
shall have no obligation with respect to this Agreement, except the obligation
to notify the parties regarding the status of the deposit account as required in
Section 2.2 below.

1.3 Deposit Inspection. When DSI receives the deposit materials and the Exhibit
A, DSI will conduct a deposit inspection by visually matching the labeling of
the tangible media containing the deposit materials to the item descriptions and
quantity listed on the Exhibit A. In addition to the deposit inspection,
Preferred Beneficiary may elect to cause a verification of the deposit materials
in accordance with Section 1.6 below.

1.4 Acceptance of Deposit. At completion of the deposit inspection, if DSI
determines that the labeling of the tangible media matches the item descriptions
and quantity on Exhibit A, DSI will date and sign the Exhibit A and mail a copy
thereof to Depositor and Preferred Beneficiary. If DSI determines that the
labeling does not match the item descriptions or quantity on the Exhibit A, DSI
will (a) note the discrepancies in writing on the Exhibit A; (b) date and sign
the Exhibit A with the exceptions noted; and (c) provide a copy of the Exhibit A
to Depositor and Preferred Beneficiary. DSI's acceptance of the deposit occurs
upon the signing of the Exhibit A by DSI. Delivery of the signed Exhibit A to
Preferred Beneficiary is Preferred Beneficiary's notice that the deposit
materials have been received and accepted by DSI.

1.5 Depositor's Representations. Depositor represents as follows:

        a.      Depositor lawfully possesses all of the deposit materials
                deposited with DSI;

        b.      With respect to all of the deposit materials, Depositor has the
                right and authority to grant to DSI and Preferred Beneficiary
                the rights as provided in this Agreement;

        c.      The deposit materials are not subject to any lien or other
                encumbrance;

        d.      The deposit materials consist of the proprietary information and
                other materials identified in the license agreement; and

        e.      The deposit materials are readable and useable in their current
                form or, if the deposit materials are encrypted, the decryption
                tools and decryption keys have also been deposited.

1.6 Verification. Preferred Beneficiary shall have the right, at Preferred
Beneficiary's expense, to cause a verification of any deposit materials. A
verification determines, in different levels of detail, the accuracy,
completeness, sufficiency and quality of the deposit materials. If a
verification is elected after the deposit materials have been 


<PAGE>   52

delivered to DSI, then only DSI, or at DSI's election an independent person or
company selected and supervised by DSI, may perform the verification.

1.7 Deposit Updates. Unless otherwise provided by the license agreement,
Depositor shall update the deposit materials within 90 days of each release of a
new version of the product which is subject to the license agreement. Such
updates will be added to the existing deposit. All deposit updates shall be
listed on a new Exhibit A and the new Exhibit A shall be signed by Depositor.
Each Exhibit B will be held and maintained separately within the escrow account.
An independent record will be created which will document the activity for each
Exhibit A. The processing of all deposit updates shall be in accordance with
Sections 1.2 through 1.6 above. All references in this Agreement to the deposit
materials shall include the initial deposit materials and any updates.

1.8 Removal of Deposit Materials. The deposit materials may be removed and/or
exchanged only on written instructions signed by Depositor and Preferred
Beneficiary, or as otherwise provided in this Agreement.


ARTICLE 2  -- CONFIDENTIALITY AND RECORD KEEPING

2.1 Confidentiality. DSI shall maintain the deposit materials in a secure,
environmentally safe, locked facility which is accessible only to authorized
representatives of DSI. DSI shall have the obligation to reasonably protect the
confidentiality of the deposit materials. Except as provided in this Agreement,
DSI shall not disclose, transfer, make available, or use the deposit materials.
DSI shall not disclose the content of this Agreement to any third party. If DSI
receives a subpoena or other order of a court or other judicial tribunal
pertaining to the disclosure or release of the deposit materials, DSI will
immediately notify the parties to this Agreement. It shall be the responsibility
of Depositor and/or Preferred Beneficiary to challenge any such order; provided,
however, that DSI does not waive its rights to present its position with respect
to any such order. DSI will not be required to disobey any court or other
judicial tribunal order. (See Section 7.5 below for notices of requested
orders.)

2.2 Status Reports. DSI will issue to Depositor and Preferred Beneficiary a
report profiling the account history at least semi-annually. DSI may provide
copies of the account history pertaining to this Agreement upon the request of
any party to this Agreement.

2.3 Audit Rights. During the term of this Agreement, Depositor and Preferred
Beneficiary shall each have the right to inspect the written records of DSI
pertaining to this Agreement. Any inspection shall be held during normal
business hours and following reasonable prior notice.

<PAGE>   53

ARTICLE 3  --  GRANT OF RIGHTS TO DSI

3.1 Title to Media. Depositor hereby transfers to DSI the title to the media
upon which the proprietary information and materials are written or stored.
However, this transfer does not include the ownership of the proprietary
information and materials contained on the media such as any copyright, trade
secret, patent or other intellectual property rights.

3.2 Right to Make Copies. DSI shall have the right to make copies of the deposit
materials as reasonably necessary to perform this Agreement. DSI shall copy all
copyright, nondisclosure, and other proprietary notices and titles contained on
the deposit materials onto any copies made by DSI. With all deposit materials
submitted to DSI, Depositor shall provide any and all instructions as may be
necessary to duplicate the deposit materials including but not limited to the
hardware and/or software needed.

3.3 Right to Transfer Upon Release. Depositor hereby grants to DSI the right to
transfer the deposit materials to Preferred Beneficiary upon any release of the
deposit materials for use by Preferred Beneficiary in accordance with Section
4.5. Except upon such a release or as otherwise provided in this Agreement, DSI
shall not transfer the deposit materials.


ARTICLE 4  -- RELEASE OF DEPOSIT

4.1 Release Conditions. As used in this Agreement, "Release Conditions" shall
mean the occurrence of Depositor's material failure to support the Products (as
defined in the license agreement) in accordance with Section 9(b) of the license
agreement following written notice thereof from SDTI and a thirty-five (35) day
period to cure, as set forth in Section 9(g) of the license agreement.

4.2 Filing For Release. If Preferred Beneficiary believes in good faith that a
Release Condition has occurred, Preferred Beneficiary may provide to DSI written
notice of the occurrence of the Release Condition and a request for the release
of the deposit materials. Upon receipt of such notice, DSI shall provide a copy
of the notice to Depositor, by certified mail, return receipt requested, or by
commercial express mail.

4.3 Contrary Instructions. From the date Depositor receives the notice
requesting release of the deposit materials, Depositor shall have ten business
days to deliver to DSI Contrary Instructions. "Contrary Instructions" shall mean
the written representation by Depositor that a Release Condition has not
occurred or has been cured. Upon receipt of Contrary Instructions, DSI shall
send a copy to Preferred Beneficiary by certified mail, return receipt
requested, or by commercial express mail. Additionally, DSI shall notify both
Depositor and Preferred Beneficiary that there is a dispute to be resolved
pursuant to the Dispute Resolution section (Section 7.3) of this Agreement.
Subject to Section 5.2, DSI will continue to store the deposit materials without
release pending (a) joint 


<PAGE>   54

instructions from Depositor and Preferred Beneficiary; (b) resolution pursuant
to the Dispute Resolution provisions; or (c) order of a court.

4.4 Release of Deposit. If DSI does not receive Contrary Instructions from the
Depositor, DSI is authorized to release the deposit materials to the Preferred
Beneficiary or, if more than one beneficiary is registered to the deposit, to
release a copy of the deposit materials to the Preferred Beneficiary. However,
DSI is entitled to receive any fees due DSI before making the release. This
Agreement will terminate upon the release of the deposit materials held by DSI.

4.5 Right to Use Following Release. Unless otherwise provided in the license
agreement, upon release of the deposit materials in accordance with this Article
4, Preferred Beneficiary shall have the right to use the deposit materials for
the sole purpose of continuing the benefits afforded to Preferred Beneficiary by
Section 9(b) of the license agreement. Preferred Beneficiary shall be obligated
to maintain the confidentiality of the released deposit materials.


ARTICLE 5  --  TERM AND TERMINATION

5.1 Term of Agreement. The initial term of this Agreement is for a period of one
year. Thereafter, this Agreement shall automatically renew from year-to-year
unless (a) Depositor and Preferred Beneficiary jointly instruct DSI in writing
that the Agreement is terminated; or (b) the Agreement is terminated by DSI for
nonpayment in accordance with Section 5.2. If the deposit materials are subject
to another escrow agreement with DSI, DSI reserves the right, after the initial
one year term, to adjust the anniversary date of this Agreement to match the
then prevailing anniversary date of such other escrow arrangements.

5.2 Termination for Nonpayment. In the event of the nonpayment of fees owed to
DSI, DSI shall provide written notice of delinquency to all parties to this
Agreement. Any party to this Agreement shall have the right to make the payment
to DSI to cure the default. If the past due payment is not received in full by
DSI within one month of the date of such notice, then DSI shall have the right
to terminate this Agreement at any time thereafter by sending written notice of
termination to all parties. DSI shall have no obligation to take any action
under this Agreement so long as any payment due to DSI remains unpaid.

5.3 Disposition of Deposit Materials Upon Termination. Upon termination of this
Agreement by joint instruction of Depositor and Preferred Beneficiary, DSI shall
destroy, return, or otherwise deliver the deposit materials in accordance with
Depositor's instructions. Upon termination for nonpayment, DSI may, at its sole
discretion, destroy the deposit materials or return them to Depositor. DSI shall
have no obligation to return or destroy the deposit materials if the deposit
materials are subject to another escrow agreement with DSI.


<PAGE>   55

Agreement, the following provisions of this Agreement shall survive:

        a.      Depositor's Representations (Section 1.5);

        b.      The obligations of confidentiality with respect to the deposit
                materials;

        c.      The rights granted in the sections entitled Right to Transfer
                Upon Release (Section 3.3) and Right to Use Following Release

                occurred prior to termination;

        d.      The obligation to pay DSI any fees and expenses due;

        e.      The provisions of Article 7; and

applicable to the services provided. DSI shall notify the party responsible for

prior to rendering the service, if requested.

6.2 Payment Terms. DSI shall not be required to perform any service unless the
payment for such service and any outstanding balances owed to DSI are paid in

on past due amounts shall accrue at the rate of one and one-half percent per
month (18% per annum) from the date of the invoice.


ARTICLE 7  --  LIABILITY AND DISPUTES

7.1 Right to Rely on Instructions. DSI may act in reliance upon any instruction,
instrument, or signature reasonably believed by DSI to be genuine. DSI may
assume that any employee of a party to this Agreement who gives any written
notice, request, or instruction has the authority to do so. DSI shall not be
responsible for failure to act as a result of causes beyond the reasonable
control of DSI.

this Agreement and to act in a reasonable and prudent manner with regard to this
escrow 

<PAGE>   56

arrangement. Provided DSI has acted in the manner stated in the preceding
sentence, Depositor and Preferred Beneficiary each agree to indemnify, defend
and hold harmless DSI from any and all claims, actions, damages, arbitration
fees and expenses, costs, attorney's fees and other liabilities incurred by DSI
relating in any way to this escrow arrangement.

7.3 Dispute Resolution. Any dispute relating to or arising from this Agreement
shall be resolved by arbitration under the Commercial Rules of the American

Beneficiary, arbitration will take place in San Diego, California, U.S.A. Any
court having jurisdiction over the matter may enter judgment on the award of the
arbitrator(s). Service of a petition to confirm the arbitration award may be

accordance with the laws of the State of California, without regard to its
conflict of law provisions.

or refrain from taking any action, that party shall:

        a.     Give DSI at least two business days' prior notice of the hearing;

        b.     Include in any such order that, as a precondition to DSI's
               obligation, DSI be paid in full for any past due fees and be paid
               for the reasonable value of the services to be rendered pursuant
               to such order; and

        c.     Ensure that DSI not be required to deliver the original (as
               opposed to a copy) of the deposit materials if DSI may need to
               retain the original in its possession to fulfill any of its other
               duties.

ARTICLE 8  --  GENERAL PROVISIONS

8.1 Entire Agreement. This Agreement, which includes the Exhibits described
herein, embodies the entire understanding among the parties with respect to its
subject matter and supersedes all previous communications, representations or
understandings, either oral or written. No amendment or modification of this
Agreement shall be valid or binding unless signed by all the parties hereto,

Agreement, all documents and communications may be delivered by First Class
mail.

8.3 Severability. In the event any provision of this Agreement is found to be
invalid, voidable or unenforceable, the parties agree that unless it materially
affects the entire intent and purpose of this Agreement, such invalidity,

Agreement nor the remaining provisions herein, and the provision in question
shall be deemed to be replaced with a valid and enforceable provision most
closely reflecting the intent and purpose of the original provision.

benefit of the successors and assigns of the parties. However, DSI shall have no
obligation in performing this Agreement to recognize any successor or assign of
Depositor or Preferred Beneficiary unless DSI receives clear, authoritative and
conclusive written evidence of the change of parties.

Territory.

        5.2 Distributor shall not furnish Products to End Users outside the

application, and Distributor agrees to indemnify and hold Licensor and its
suppliers harmless from any claims for loss, cost, damage, expense or liability
arising out of or in connection with the use and performance of the Software in

decided by the parties through good faith negotiations. Licensor further

managerial capabilities necessary to vigorously promote the distribution and use

specifically set forth in the documentation provided by Licensor.

        7.6 The Software shall be provided to Distributor AS IS. Licensor does

errors that become known to Licensor.

        7.7 Licensor warrants that it has sufficient right and authority to
grant to Distributor all of the licenses and rights granted under this
Agreement.

        7.8 THE WARRANTIES CONTAINED IN THIS AGREEMENT ARE THE ONLY WARRANTIES

<PAGE>   7
                                       7



ARE IN LIEU OF ALL OTHER WARRANTIES NOT EXPRESSLY SET FORTH HEREIN. LICENSOR AND
DISTRIBUTOR EACH DISCLAIM ALL OTHER WARRANTIES, WHETHER EXPRESS OR IMPLIED,
INCLUDING WITHOUT LIMITATION THE IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS
FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT.

        7.9 Each party represents and warrants that it is authorized to enter
into this Agreement, and to fully perform the undertakings set forth herein, and
that it is not a party to any other agreement or under any obligation or
restriction which would prevent it from entering into this Agreement or which
would adversely affect this Agreement or the performance of the obligations and
undertakings set forth herein.

        7.10 The parties expressly agree that they shall in no event be liable
to each other or to any End User for any loss of profit, or any incidental,
special, exemplary, or consequential damages claimed against the other,
regardless of whether such party has been previously advised of the possibility
of such claims or demands.

ARTICLE 8. PAYMENT OF FEES

        8.1 For each quarter during the term of this Agreement, Distributor
shall make a non-refundable payment of Product Fees to Licensor according to the
schedule shown in Exhibit C. The parties acknowledge that the amount of such
fees is based on the Licensor's list price. From time to time Licensor may deem
it necessary to change the list price of Products, and the amount of license
fees shall be changed accordingly; provided that Licensor shall give Distributor
upon at least ninety (90) days' prior written notice of such change unless
otherwise agreed. Licensor shall not raise prices more than 10% in any given
calendar year. In the event of any change in prices, the amount of Product Fees
shall be calculated by applying the percentage discounts indicated in Exhibit C,
and shall apply to all orders received by Licensor after the effective date of
such price change. Additional Product Fees accrued in any quarter in excess of
the amount of pre-payment to be credited will be due within 30 days of the
monthly report for the month in which they were accrued.

        8.2 In addition to the Product Fees described in the preceding
paragraph, Distributor shall pay to Licensor a non-refundable Software
Maintenance Fee in the amount of [ ** ] per quarter during both the Initial Term
and renewed Terms of this Agreement. Such payments shall commence from Q4 1997
and shall be made each quarter within 45 days from the start of the quarter. The
Software Maintenance Fee shall cover services such as bug fixes, technical
support, and minor revisions of the Software. Major upgrades of Software are not
covered by the Software Maintenance Fee, but shall be treated as separate
Products subject to a Product Fee, which shall be calculated at the percentages
shown for Volume Discounts of Products in Exhibit C, based on the Licensor's
list price charged for such upgrade.

        8.3 Should Distributor begin charging support fees to its customers,
Licensor and Licensee shall discuss in mutual good faith an equitable
apportionment of such fees to be paid to Licensor.

        8.4 Although Licensor may publish suggested wholesale or retail prices,
these are

<PAGE>   8
                                       8



suggestions only, and Distributor will be entirely free to determine the actual
prices and license fees at which Products will be furnished to End Users.

        8.5 In addition to the payment schedule for Product Fees shown in
Exhibit C, Distributor shall have the right to negotiate either a "Site License"
or "Large Volume Deal" involving more than [ ** ] units up to [ ** ] times per
year. The Product Fee for such transactions shall be separately agreed between
the parties. Such transactions shall not be credited in computing any applicable
Volume Discounts.

        8.6 All amounts payable to Licensor under this Agreement are exclusive
of all national, state or local sales, use, value added or other taxes, customs
duties, or similar tariffs and fees. Distributor will pay all taxes and duties
assessed by any authority in connection with this Agreement and its performance,
except for taxes payable on Licensor's net income. Distributor represents and
warrants to Licensor that all Products acquired hereunder are for redistribution
in the ordinary course of Distributor's business, and Distributor agrees to
provide Licensor with appropriate resale certificate numbers and other
documentation satisfactory to the applicable taxing authorities to substantiate
any claim of exemption from any such taxes or fees. Distributor will pay any
withholding taxes required by applicable law and supply Licensor with evidence
of payment of such withholding tax, in a form acceptable for Licensor to meet
the requirements for claiming foreign tax credits on Licensor's U.S. income tax
return. The Parties acknowledge that certain payments may be subject to reduced
withholding tax rates under applicable tax treaties, and each shall made its
best efforts to take all reasonable steps and obtain all necessary documents and
approvals so that the payments under this Agreement will be subject only to such
reduced withholding rates.

        8.7 All payments shall be made in United States dollars, free of any
currency control or other restrictions to Licensor by wire transfer to an
account designated by Licensor. Interest shall accrue on any delinquent amounts
owed by Distributor for Products at the lesser of eighteen percent (18%) per
annum or the maximum rate permitted by applicable usury law.

ARTICLE 9. TERMINATION

        9.1 If either party wishes to terminate this Agreement for a material
breach of any of the terms or obligations herein, such party shall first notify
the other of the breach and discuss how the breach may be remedied. If the
breach is not remedied within 30 days after notice has been given and a
discussion has been made in good faith, the party giving notice of the breach
may then terminate the agreement by giving written notice of termination.

        9.2 If this Agreement is terminated, Distributor shall remain liable to
pay the Product Fees on any and all Products sold prior to or after such
termination, except as provided in the following paragraph.

        9.3 In the event that Licensor enters into a new distribution agreement
for the Software in Territory with a party other than Distributor upon the
termination or expiration of this Agreement, Licensor or such third party shall
be entitled to purchase any Products remaining unsold in Distributor's
possession, for Distributor's actual cost of production, plus any applicable
handling, transportation, or other costs. Distributor shall be relieved of the
obligation to pay royalties on such Products sold to a new distributor.
Provided, however, that

<PAGE>   9
                                       9



if Licensor enters into such a new distribution agreement notwithstanding the
fact Distributor has fulfilled all of its obligations under this Agreement, then
Licensor or such third party shall be required to purchase all Products
remaining unsold in Distributor's possession as described above.

        9.4 Upon expiration or termination of this Agreement, Distributor shall
cease using the Marks, and shall remove any Marks from its cards, stationery, or
other materials.

ARTICLE 10. NO DAMAGES ON TERMINATION OR EXPIRATION; GOOD FAITH DISCUSSIONS

        10.1 Neither party shall be liable to the other for damages of any kind,
including incidental or consequential damages, on account of the termination or
expiration of this Agreement in accordance with its terms. Such waiver includes
without limitation any claim of reimbursement or damages for the loss of good
will, prospective profits, or anticipated income, or on account of any
expenditures, investments, leases, or commitments made by either party based on
this Agreement; or any right either party may have to receive compensation or
reparations under the law of the Territory or otherwise upon the termination ore
expiration of this Agreement; except as specifically included herein.

        10.2 In the event that this Agreement expires or is terminated through
no fault of Distributor, the parties shall discuss, in good faith and without
obligation, possible ways in which Distributor may continue to participate in
the distribution of Software in the Territory. Such discussions should include
such alternatives as whether Distributor might participate in a joint venture,
offer consulting services, enter into a non-exclusive distribution arrangement,
and any other reasonable possibilities that are worthy of consideration at that
time.

        10.3 The provisions of this Section 10 shall survive the expiration or
termination of this Agreement.

ARTICLE 11. USE OF THE MARKS

        11.1 Distributor may use the Marks only in accordance with Licensor's
guidelines for the purpose of identifying and marketing the Products, and on
business cards and stationery indicating that Distributor is an authorized
distributor of Licensor's software, including the Software. The Marks shall be
included in the packaging of the Products in accordance with Licensor's
marketing guidelines.

        11.2 Distributor shall not apply to register any trademarks, trade
names, service marks, symbols, or logos that are the same or similar to those of
Licensor. Distributor shall not use the Marks or any similar Marks after the
termination or expiration of this Agreement.

        12.1 Confidential Information means both (i) the terms and conditions of
this Agreement, and (ii) any and all proprietary information and data furnished

        13.1 This Agreement has been reached as the result of an arm's-length
negotiation between independent parties, and it shall be construed and
interpreted accordingly.

        13.2 Nothing in this Agreement shall be construed to create any sort of
partnership, joint venture, employer-employee, or agency relationship between
the parties. Except for the required End User License, neither party shall have,
or represent itself to have, any power or authority to enter into any agreement
or obligation on behalf of the other, or legally to bind the other, without
first receiving express authorization therefor.

ARTICLE 14.    GOVERNMENT CONSENT

        14.1 The obligations to be performed under this Agreement are subject to
the condition of receiving all necessary governmental approvals.

        14.2 Distributor shall notify Licensor of any changes to the Products,
the End User Licenses, documentation, or other materials that must be made to
comply with the applicable laws and regulations. In the event that the changes
required by such laws or regulations are so significant as to require
substantial costs for compliance which materially affect the price of the
Products, the parties shall meet and confer in good faith as to how such costs
shall be

                                       11



apportioned.

ARTICLE 15. RECORD-KEEPING

        Distributor shall keep complete records of its distribution of all
Products, including the End User name, ultimate destination, version of the
Software, serial numbers, and the date of sale, lease, or other disposition.
Distributor will make such records available to Licensor upon reasonable
request.

ARTICLE 16. NOTICE

        16.1 All notices required to be given under this Agreement shall be
given in writing, and delivered by mail (postage prepaid), confirmed facsimile
transmission, or personal delivery to the addresses first set forth above or
which from time to time notice is given by each party to the other.

        16.2 For the purposes of this Agreement, notices given by mail shall be
deemed effective ten (10) days after sending; notices given by confirmed
facsimile shall be deemed effective on the first business day following the date
of receipt; and notices given by personal delivery shall be effective upon

        16.3 In addition to the methods of notice required by this Article, the
parties shall use their best efforts to utilize the telephone, electronic mail,
and other means of communication to promptly and effectively communicate
concerning their responsibilities, duties and obligations under this Agreement.

ARTICLE 17. INJUNCTIVE RELIEF

        The parties each acknowledge that they will be irreparably harmed if the
other fails to comply with its obligations under this Agreement, and that it
would not have an adequate remedy at law in the event of an actual or threatened
breach of this Agreement. Each party therefore agrees that the other may seek
injunctive relief or other order for specific performance for any actual or
threatened violations without the need to first post a bond therefor.

ARTICLE 18. FORCE MAJEURE

perform attributable to any cause beyond its reasonable control, including
without limitation fire, explosion, windstorm, decree or act of any government,

warlike activities, the inability to obtain fuel, raw materials, components,

connection with any matters related to or arising out of this Agreement.
