ITEM 1. BUSINESS

    Open Market is a leading provider of e-business application software and
software services that enable its customers to manage and deliver online
content, engage in personalized online marketing and merchandizing campaigns and
conduct commerce via a secure, reliable, flexible transaction processing and
order management system. We believe that the combination of these three enabling
capabilities creates a cost-efficient, rapidly deployable e-business solution
that provides a more engaging, personalized user experience.

    Our e-business application suite is built on an open standards-based
architecture that is scalable and easily adaptable to the evolving business
requirements of our customers. We currently offer three principal products:

    - Internet Publishing System (IPS), our integrated publishing system that
      provides content management and the dynamic delivery of personalized
      information;

    - Transact, our comprehensive order management and transaction processing
      system; and

    - ShopSite, our Web storefront building software for small and medium size
      businesses.

    Our products enable the delivery of content and commercial offers through a
broad range of media, including Web browsers and cell phones, personal digital
assistants and other wireless devices.

INDUSTRY BACKGROUND

    The emergence and widespread acceptance of the Internet as a communication
and commerce medium has changed the way businesses interact with each other and
their customers. The Internet offers businesses the opportunity to establish new
revenue streams and distribution channels, enhance relationships with customers
and partners and improve employee productivity. Companies seeking to utilize
this powerful new medium face several challenges, including managing and
delivering content effectively through the Internet, conducting online marketing
and personalization and enabling secure electronic commerce.

    THE NEED TO MANAGE AND DELIVER CONTENT EFFECTIVELY AND
EFFICIENTLY.  Increasingly, companies are turning to the Internet as the primary
vehicle for information delivery. Online business requires effective management
and delivery of information to customers, partners and employees. Forrester
Research indicates that, over the past year, many companies have doubled the
amount of information they publish on the Internet and predicts that this trend
will continue over the next year. In order to address this growth, companies are
increasingly demanding software systems that automate the workflow of content
creation, management and delivery.

    THE NEED TO CREATE A PERSONALIZED CUSTOMER EXPERIENCE.  In an effort to
create more engaging, profitable online businesses, companies are seeking to
deliver dynamic, personalized content. Many companies are initiating marketing
strategies to attract new visitors to their Web sites, motivate purchases and
build loyalty. These initiatives require companies to collect and analyze
customer preferences, behavior and purchase histories so that they may
effectively deliver content and commercial offers in ways that maximize revenue
opportunities.

    THE NEED TO CONDUCT COMMERCE ON THE INTERNET.  According to International
Data Corporation, the volume of e-commerce transactions is projected to increase
from $218 billion in 2000 to $1.3 trillion in 2003. To satisfy this increased
volume, commerce sites must be highly scalable and reliable and must support:

    - secure transaction processing;

                                       3
<PAGE>
    - real-time credit card authentication;

    - multiple payment types;

    - partial shipments and back orders;

    - on-line customer service; and

    - real-time order status.

    THE NEED TO COMBINE CONTENT, MARKETING AND COMMERCE.  Historically, in order
to combine content management, online marketing and personalization and commerce
functionality into a complete e-business solution, companies either built their
own solutions or installed and integrated products from multiple vendors. Both
of these approaches are complicated and involve long implementation periods and
substantial up-front and on-going expenditures.

    THE NEED FOR OPEN ARCHITECTURES.  Many first generation applications are
based on closed, proprietary architectures and outmoded scripting languages.
These applications are often more difficult to maintain and adapt to changing
business requirements because they are less compatible with other systems and
require personnel with technical skills that are in shorter supply.

THE OPEN MARKET SOLUTION

    We offer an integrated packaged suite of e-business software products and
services that enable our customers to manage and deliver online content, engage
in personalized online marketing and merchandizing campaigns and conduct
commerce via a secure, reliable and flexible transaction processing and order
management system. Our solution enables organizations to: rapidly deploy our
software; actively deliver personalized information to customers through the
Internet to Web browsers and to wireless and other devices; and minimize the
cost of implementation, integration and on-going ownership of e-business
software applications.

    The diagram below illustrates the key e-business functions supported by our
products:

management products as well as the features of our online personalization
functionality.]

<PAGE>
    CONTENT MANAGEMENT.  Our content management products streamline the Internet
publishing process, enabling customers to effectively publish large, dynamic,
content-rich Web sites. Our products:

    - automate content acquisition from a broad range of sources, including
      legacy databases, news feeds and other syndicated content sources;

    - enable non-technical personnel to easily create and update Web site
      content and rules governing the delivery of personalized content and
      commercial offers;

    - incorporate an industry-tested publishing workflow methodology derived
      from our extensive experience with publishers of some of the world's
      largest and most heavily used on-line media sites; and

    - separate content from the form in which it is displayed, enabling our
      customers to use content in a variety of formats and to deliver content
      both to personal computers and to devices, such as cell phones, personal
      digital assistants and other wireless devices, supported by the Wireless
      Application Protocol (WAP).

    ONLINE MARKETING AND PERSONALIZATION.  Our software products facilitate the
dynamic delivery of personalized content and commercial offers to individuals
and groups of users by:

    - supporting a variety of personalization techniques, including
      authentication, visitor profiling and rules-based recommendations;

    - providing an integrated analysis of transaction data and visitor profile
      information for more effective creation and assessment of marketing and
      merchandizing campaigns; and

    - supporting digital offers and digital coupons that allow merchants to use
      a variety of digital media, including the Web, wireless, e-mail, "push"
      technology and CD-ROM, to distribute special offers and discounts.

    COMMERCE MANAGEMENT.  Our commerce management products, built on more than
five years of in-market use, are capable of supporting broad commerce
requirements for both business-to-business and business-to consumer
applications. Our products support:

    - multiple types of payment such as purchase orders, credit cards,
      procurement cards, micro-transactions and secure electronic transactions
      (SETs), debit cards, smart cards and frequent buyer points;

    - multiple currencies;

    - multiple selling models, including physical goods, digital goods,
      subscriptions, auctions and catalogs;

    - back orders, partial orders and real-time order status;

    - integration with Enterprise Resource Planning (ERP) and other existing
      systems; and

    - multiple business units and channel partners.

    AN INTEGRATED SUITE OF FULL-FEATURED APPLICATIONS.  Our suite of application
products provides integrated management of a broad range of critical e-business
functions. We believe that our packaged applications enable our customers to
deploy a broad level of functionality more rapidly than they otherwise could by
building their own solutions in-house "from the ground up" or by installing and
integrating products from multiple vendors.

    AN OPEN PLATFORM.  Our content management products are built on an open
application server environment, and make use of programming standards such as
XML and Java. Open, standards-based applications can be easily customized and
more readily integrated with existing and third-party applications. Our commerce
management products are based upon our distinctive SecureLink architecture that
addresses the unique requirements of conducting business on the Web. SecureLink
provides the freedom to establish

                                       5
<PAGE>
an electronic presence using virtually any system platform, any Web server
software and any authoring software or data repository. Similarly, SecureLink
imposes few constraints on buyers, allowing them to make purchases from
virtually any Web-enabled client.

STRATEGY

    Our objective is to be the leading provider of a comprehensive, packaged
e-business suite of software applications. The key elements of our strategy to
achieve this objective are as follows:

    EXPAND OUR SUITE OF E-BUSINESS PRODUCTS.  We plan to enhance and expand our
suite of e-business product and service offerings. We have planned major
releases of our content management and commerce management products, as well as
a number of new product releases, for the first half of 2000. These additions to
our e-business suite are expected to focus on online catalog creation and
management, content syndication, online marketing management and data analysis
and personalization.

    INCREASE DIRECT SALES AND INDIRECT DISTRIBUTION CHANNELS.  Over the last
five years, we have made significant investments to establish global direct and
indirect distribution channels. As of December 31, 1999, we had a direct
field-based sales force of approximately 100 people worldwide, 62 of whom were
quota carrying sales representatives. We plan to substantially increase the
number of sales representatives by the end of 2000. We believe our team of sales
professionals have the experience required for complex solution selling. We also
plan to expand our indirect sales channels through an enhanced partner program
which offers a comprehensive training curriculum, new co-marketing
opportunities, and developer-level support.

    EXPAND RELATIONSHIPS WITH SYSTEMS INTEGRATORS.  We have established
relationships with several large domestic and international systems integrators
and consulting firms. We believe these firms have substantial influence over
software purchasing decisions. In addition, these companies aid in the
successful implementation and support of our software products. We believe that
building on our established relationships and creating new relationships with
these partners will enable us to sell additional products to our existing
customer base and gain new customers more rapidly.

    INCREASE MARKETING FOCUS.  Our marketing strategy focuses on communicating
the possibilities of value creation through the use of our e-business solution
suite. We focus primarily on large enterprises and leading Internet-related
businesses. Within that market, we intend to target business-to-business,
business-to-consumer, financial services, Internet/intranet publishing and media
and Internet portals and marketplaces.

    PURSUE STRATEGIC TECHNOLOGY ALLIANCES TO ADD VALUE TO OUR SOLUTIONS.  We
seek to integrate third-party technology into our products that will improve the
ability of our customer to use the Internet as a vital business medium. We
maintain relationships with strategic technology vendors designed to extend and
enhance the functionality of our products, particularly in the areas of
personalization and online marketing. We plan to continue to extend our existing
partnerships as well as identify and partner with additional vendors that can
add value to our solutions.

    BROADEN INTERNATIONAL PRESENCE.  To more effectively sell to and support a
growing global customer base, we have increased our direct sales and service
organizations outside of the United States. We have also established
distribution relationships in several countries, including Brazil, Hong Kong,
India, Israel, Korea, Malaysia, The Netherlands, Singapore and South Africa. We
expect to increase our international sales, marketing and services staff and
expand our international distributor channel through our enhanced partner
program.

    EXTEND TECHNOLOGY LEADERSHIP.  We intend to continue to devote substantial
resources to the development of innovative new products and technology for our
e-business solutions. Since we began operations in April 1994, we have obtained
several patents asserting claims relating to certain aspects or uses of
electronic commerce software. We have also developed a substantial knowledge
base resulting from our

                                       6
<PAGE>
experience with a large number of customers conducting Internet commerce,
content management and delivery. We intend to combine our extensive market
experience with the latest Internet technologies to continue to create leading
e-business solutions. We are also committed to supporting open standards in our
products and technologies in an effort to ensure that our customers will be able
to adapt and customize our solutions and more easily integrate them with
existing systems.

bulletins, status reports and ongoing communications regarding new features and
products under development.

    PROFESSIONAL SERVICES.  Our professional services group works closely with
our system integrator partners to provide project leadership and guidance in
installing, customizing and supporting Open Market products. Our professional
services range from internet commerce business planning to solution design and
implementation.

    EDUCATION SERVICES.  Our education services group provides customers and
systems integrators with in-depth training for all our current products. We hold
classes regularly at training facilities in our regional service centers and we
offer customized training solutions for our customers and partners.

RESEARCH AND PRODUCT DEVELOPMENT

    We believe our future success will depend in large part on our ability to
develop technologies that address the evolving needs of our customers.
Accordingly, we intend to expand and enhance our existing product offerings and
introduce new products. Our customers and partners provide significant product
feedback that is channeled into product development and innovation. While we
expect that certain of our new products will be developed internally, we may,
based on timing and cost considerations, expand our product offerings through
acquisitions and partnerships. In addition, we may use external development
resources for certain of our products and product components.

    Since our inception, we have made substantial investments in product
development and related activities. As of December 31, 1999, we had 133
employees and independent contractors devoted to product development. Our
research and development expenses were approximately $22.4 million,
$25.9 million and $28.3 million in 1999, 1998 and 1997, respectively.

CUSTOMERS AND MARKETS

    Our software products are used by more than 500 large enterprises worldwide
across a broad spectrum of markets, including business-to-business,
business-to-consumer, financial services, Internet/ intranet publishing and
media, and Internet portals and marketplaces. These businesses take advantage of
our solutions either directly by deploying the software within their own
enterprises, or indirectly by procuring services from commerce service providers
running our software. These commerce service providers offer commerce services
to small and medium size companies that wish to outsource the cost and
complexity associated with implementing and maintaining software solutions
within their own organizations. As of December 31, 1999 more than 80 commerce
service providers had purchased software from us. In addition, we have sold more
than 35,000 licenses for our ShopSite Web storefront building software for
smaller merchants.

COMPETITION

    The market for Internet business applications and services is relatively
new, intensely competitive, quickly evolving and subject to rapid technological
change. We expect competition to continue to increase in the future. Our
products compete with custom solutions developed in-house by prospective
customers, as well as products from competing software vendors such as Art
Technology Group (ATG), BroadVision, IBM, InterShop, InterWorld, Interwoven,
Microsoft, Oracle, Vignette and others. Some of our current and potential
competitors have longer operating histories, greater name recognition, larger
installed customer bases and significantly greater financial, technical and
marketing resources than we do. As a result, these competitors may be able to
develop and expand their product offerings more quickly, adapt more swiftly to
new or emerging technologies and changes in customer demand, devote greater
resources to the marketing and sale of their products, pursue acquisitions and
other opportunities more readily and adopt more aggressive pricing policies.

    Competitive factors in the Internet-based software and services market
include innovative technology, breadth of product features, product quality,
marketing and distribution resources, customer service and support and price.
While we have demonstrated our ability to compete, there can be no assurance
that we will be able to compete successfully against current or future
competitors.

DISTRIBUTION CHANNELS

    Our objective is to achieve broad market penetration by employing multiple
distribution channels, including direct sales, distributors and resellers,
original equipment manufacturers, systems integrators and commerce service
providers.

    DIRECT SALES AND DISTRIBUTORS.  We market and sell our software and services
primarily through our worldwide direct sales force of approximately 100 people
from offices throughout the United States and in Australia, Canada, France,
Germany, Italy, Japan, The Netherlands and the United Kingdom. We are
represented by distributors in countries where we do not have a direct sales
force, including Brazil, Hong Kong, India, Israel, Korea, Malaysia, Singapore
and South Africa.

                                       11
<PAGE>
    SYSTEMS INTEGRATORS.  We have also entered into agreements to provide
training, support, marketing and sales assistance to a number of leading system
integrators which sell, install and support our products, including Agency.com,
Arthur Andersen, Cambridge Technology Partners, CSC Consulting, Deloitte
Consulting, IBM Global Services, iXL, PricewaterhouseCoopers, US Interactive and
Whittman-Hart.

    COMMERCE SERVICE PROVIDERS.  Commerce service providers collectively have
the potential to deliver the benefits of our software to small and medium-sized
businesses across the world. Our commerce service providers include many of the
world's largest telecommunications companies, such as AT&T, Barclays Bank,
Cable & Wireless, France Telecom, First Union National Bank, Nippon Telegraph &
Telephone and Swisscom.

    We also maintain relationships with hardware and operating system platform
vendors in order to achieve a high degree of functionality and integration with
their platforms. Platform vendors include Sun Microsystems and Netscape
Communications. In addition, we also maintain relationships with other key
technology partners in order to extend and enhance the functionality of our
products. Technology partners include Autonomy, Cisco Systems, ILOG, iPlanet
E-Commerce Solutions, NetMind Technologies, Net Perceptions, OpenSite
Technologies, Oracle, TAXWARE and United Parcel Service.

INTELLECTUAL PROPERTY AND LICENSES

    We rely on trademark, copyright, patent and trade secret laws, employee and
third-party non-disclosure agreements and other methods to protect our
proprietary technology. We require software licensees to enter into license
agreements that impose certain restrictions on their use of our software. In
addition, we have taken steps to avoid disclosure of our trade secrets,
including requiring those persons with access to our proprietary technology and
information to enter into confidentiality agreements with us and restricting
access to our source code. We hold several patents which assert claims for
certain aspects or uses of electronic commerce software including:

    - distributed commerce;

    - secure, real-time payment using credit and debit cards over the Internet;

    - the use of "electronic shopping carts" and session identifiers; and

    - the use of telephone numbers as URLs involving redirection by a directory
      server.

    We continually assess our technology for potential patent filings and have
additional patent applications pending in the United States relating to our
product architecture and technology.

EMPLOYEES

    As of December 31, 1999, we had 464 employees and independent contractors.
Of our total employees and independent contractors, 133 were in engineering, 150
in sales and marketing, 59 in customer service, 56 in professional services and
66 in general and administration. None of our employees is represented by a
labor union. We have not experienced any work stopages and consider our
relations with our employees to be good.

ITEM 6. SELECTED CONSOLIDATED FINANCIAL DATA

    The following selected financial information should be read in conjunction
with "Management's Discussion and Analysis of Financial Condition and Results of
Operations" and our consolidated financial statements and the related notes
included elsewhere in this report.

    The merger with FutureTense in October 1999 was accounted for as a pooling
of interests and accordingly all prior period financial data have been restated
as if the merger took place at the beginning of such periods. Our historical
data is not necessarily indicative of future results.

    The selected consolidated balance sheet information presented below as of
December 31, 1999 and 1998 and the operating information for each of the three
years in the period ended December 31, 1999, have been derived from our
consolidated financial statements that have been audited by Arthur Andersen LLP,
independent public accountants, and are included elsewhere in the report. The
selected consolidated balance sheet information as of December 31, 1997, 1996
and 1995 and the operating information for each of the two years in the period
ended December 31, 1996 have been derived from our consolidated financial
statements, audited by Arthur Andersen LLP, not appearing in this report. Arthur
Andersen LLP did not audit the financial statements of FutureTense as of
December 31, 1998, 1997, 1996, and 1995 and for the period from inception
(April 5, 1995) to December 31, 1998. Such financial statements are included in
our consolidated financial statements. These financial statements were audited
by other auditors whose report has been furnished to Arthur Andersen LLP, and
their opinion, in so far as it relates to amounts included for FutureTense, is
based solely upon the report of other auditors. The report of the other auditors
for FutureTense as of December 31, 1998, and for the two years in the period
ended December 31, 1998 is included in this report.

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

    YOU SHOULD READ THE FOLLOWING DISCUSSION OF OUR FINANCIAL CONDITION AND
RESULTS OF OPERATIONS TOGETHER WITH THE CONSOLIDATED FINANCIAL STATEMENTS AND
THE RELATED NOTES INCLUDED ELSEWHERE IN THIS REPORT. THE FOLLOWING FINANCIAL
DATA APPEAR IN THOUSANDS.

OVERVIEW

    We are a leading provider of e-business applications and software services
that enable our customers to manage and deliver online content, engage in
personalized online marketing and merchandizing campaigns and conduct commerce
via a secure, reliable, flexible transaction processing and order management
system. We believe that the combination of these three enabling capabilities
creates a cost-efficient, rapidly deployable e-business solution that provides a
more engaging, personalized user experience.

    Our e-business application suite is built on an open standards-based
architecture that is scalable and easily adaptable to the evolving business
requirements of our customers. We currently offer three principal products:

    - Internet Publishing System (IPS), our integrated publishing system that
      provides content management and the dynamic delivery of personalized
      information;

    - Transact, our comprehensive order management and transaction processing
      system; and

    - ShopSite, our Web storefront building software for small and medium size
      businesses.

    Our products enable the delivery of content and commercial offers through a
broad range of media, including Web browsers and cell phones, personal digital
assistants and other wireless devices.

    Since our inception, our business has principally focused on providing
software solutions that enable businesses to engage in business-to-business and
business-to-consumer commerce over the Internet. Over the past three years, we
made a series of acquisitions intended to complement our Internet commerce
functionality that we offer our customers. In 1997, we acquired Waypoint
Software Corporation, a provider of business-to-business catalog solutions, and
Folio Corporation, a supplier of software publishing tools. In 1998, we acquired
ICentral Incorporated, a provider of a browser-based online store-building tool
targeted at small to medium size businesses.

    In 1999, we decided to focus on our core Internet commerce business.
Accordingly, in June 1999, we formed a strategic relationship with NextPage and
granted NextPage, for a three year period, exclusive worldwide marketing and
distribution rights for the software publishing tools we acquired from Folio.
This relationship allowed us to reduce our cost structure and provided us with
minimum royalty payments from NextPage of $1,167 per quarter through June 2002.
In connection with this agreement, we also received license fees from NextPage
in the amount of $3,000 in exchange for granting NextPage a non-exclusive
worldwide right to market and distribute our commerce software products to the
commercial publishing industry.

    In October 1999, we merged with FutureTense, a provider of Web site content
management products. The goal of this merger was to create a more complete
Internet commerce solution for our customers and to strengthen our competitive
position. We have accounted for the merger as a pooling of interests.

    We recognize revenues in accordance with Statement of Position (SOP) 97-2,
SOFTWARE REVENUE RECOGNITION. We generate revenues from two sources: license
fees for the right to use our products and service revenues for technical
support, consulting and training related to our products. Our license fees
account for the majority of our revenues. We recognize license fee revenues upon
licensing and delivery of the software if there is persuasive evidence of an
agreement, there are no significant post-delivery obligations and customer
acceptance is not required. If the license is subject to customer acceptance or

                                       16
<PAGE>
significant post-delivery obligations, we defer the revenue recognition of the
license fee until customer acceptance has occurred or the post-delivery
obligations have been met. We execute separate contracts that govern the terms
and conditions of each software license and maintenance arrangement and each
professional services arrangement. We have established sufficient vendor
specific objective evidence for the value of professional services, training and
maintenance and support services based on the price charged when these elements
are sold separately. Accordingly, software license revenue is recognized under
the residual method in arrangements in which software is licensed with
professional services, training and maintenance and support services. Under the
residual method, the fair value of the undelivered elements is deferred and
subsequently recognized.

    We also enter into reseller arrangements for certain of our products that
typically provide for sublicense fees payable to us based on a percentage of our
list price. We recognize these sublicense revenues from resellers when earned,
either on a per-unit basis or, for guaranteed minimums, upon shipment of the
master copy of all our software to which the guaranteed sublicense fee minimums
relate, if there are no significant post-delivery obligations.

    Our service revenues derive from a wide variety of contracted services for
technical support, consulting and training related to our products. We charge
fees for maintenance and customer support based on a percentage, generally 20%
to 25%, of the corresponding license fee, and recognize these fees ratably over
the life of the contract. Our maintenance agreements provide for product
upgrades and enhancements and technical support in the form of telephone or
on-site assistance. These agreements are renewable at the discretion of the
customer. Accordingly, our maintenance and technical support revenues are
typically a function of new product licenses and the annual renewal of
maintenance agreements. We also generate revenues from professional services,
which include implementation and technical consulting, and from education
services, including on-site and online training services. We recognize revenues
from professional and education services as such services are performed.

    We report our revenues according to three operating segments: commerce,
content and other. Our commerce revenues include license fees and service
revenues from our Transact, LiveCommerce and ShopSite products. Our content
revenues include license fees and service revenues from our Internet Publishing
System, or IPS. For reporting purposes, we refer to the total of product and
service revenues for both commerce and content as e-business revenues. The other
revenues relate, historically, to license fees and service revenues generated
from the software publishing tools acquired from Folio and other products,
certain of which have been discontinued. After June 1999, other revenues relate
primarily to the royalties received from NextPage in accordance with our
strategic arrangement.

    Our cost of product revenues consists of costs to distribute our products,
including the cost of the media on which our products are delivered and royalty
payments to third-party vendors for technology that is incorporated into our
products. Our cost of service revenues consists primarily of the salaries and
related costs of our technical personnel.

    Software development costs that qualified to be capitalized were immaterial
in all periods. Accordingly, we have charged all such expenses to research and
development in the period incurred.

    Our customer base is diversified, with no single customer representing
greater than 10% of our total revenues for the years ended December 31, 1999,
1998 and 1997.

</TABLE>

    In 1999, total product revenues increased by $10,159 compared to 1998. Our
e-business product revenues increased $24,541 principally due to increases in
the number of product licenses entered into with new customers and follow-on
licenses with our installed base of customers. In addition, in 1999 we recorded
a full year of revenues from our content management product compared to
approximately six months of revenues from that product in 1998, since the
product was introduced in July 1998. This increase was offset by the decline of
$14,382 in other product revenues compared to 1998. This decline resulted from
decreases in license revenues from our Folio software publishing product tool.

    In 1998, total product revenues decreased by $4,668 compared to 1997. The
increase in e-business revenues of approximately $5,045 compared to 1997 was due
principally to higher sales of our commerce products. Other product revenues
decreased by $9,713 in 1998 compared to 1997. Discontinuing the licensing of
certain software products accounted for $9,400 of the reduction.

    Product revenues accounted for 65%, 68% and 79% of total revenues in 1999,
1998 and 1997, respectively. We expect that product revenues will continue to
account for the majority of total revenues for the foreseeable future.

</TABLE>

    In 1999, e-business service revenues increased by $10,425 compared to 1998
as a result of increased demand for our consulting and technical service
offerings from both new and existing customers. Commerce service revenues grew
$7,834 due to an increase in consulting projects, as well as an increase in
maintenance and support revenues from our new and installed base of customers.
Content service revenues increased significantly, primarily from the strength of
new product license business. Our content product line is relatively new to the
marketplace, and we anticipate growth in content service revenues as the volume
of our content product revenues increase. In 1999, other service revenues
declined by $2,104 compared to 1998. This decline was due to reductions in both
consulting and maintenance and support revenues from our Folio products. We do
not expect to derive any Folio service revenues during the term of the agreement
with NextPage.

    In 1998, total service revenues increased by $7,767 compared to 1997. The
e-business service revenues increased by $6,504 from 1997, primarily as a result
of a growing customer base and a developing service practice. Other service
revenues increased by $1,263 compared to 1997, primarily attributable to the
increased business volume and improvements in the marketing and delivery of our
service offerings. For 1999, 1998 and 1997, service revenues accounted for 35%,
32% and 21%, respectively, of total revenues.

</TABLE>

    In 1999 and 1998, the increased cost of product revenues was attributable
primarily to growth in product revenues and increased costs for third party
licensing royalties related to our commerce products. Our content management
products carry higher third party costs than our commerce products. As a result,
we believe that our cost of product revenues as a percentage of product revenues
will be in the range of 8% to 12% for the foreseeable future, as we incorporate
more third party technology into our products and continue to resell third party
software products with our commerce and content solutions.

    In 1999, cost of service revenues increased by $5,773 from 1998, primarily
due to growth in employee-related expenses of $1,843 and outside consulting
expenses of $3,912. During 1999, we continued to increase the number of our
professional services personnel and our use of outside consultants. We expect
that our service gross margin may decline slightly during the first six months
of 2000 as a result of continued investment in the training of our system
integrators.

    In 1998, cost of service revenues increased by $6,143 from 1997, primarily
due to increases in employee-related expenses of $3,923 and outside consulting
expenses of $543. During 1998, we continued to increase the number of our
professional services personnel and our use of outside consultants. In 1998,
service gross margin decreased approximately 3% from 1997, primarily due to an
increase in professional services personnel and lower utilization rates
resulting from extended training processes for new employees.

</TABLE>

  SELLING AND MARKETING

    Selling and marketing expenses consist primarily of the cost of sales and
marketing personnel and outside consultants, as well as the costs associated
with marketing programs, industry tradeshows, sales seminars, advertising and
product literature.

    In 1999, selling and marketing expenses increased by $3,571, primarily as a
result of an increase in commission expenses related to the increase in
revenues. In 1998, selling and marketing expenses decreased $3,307 compared to
1997. The decrease was attributable primarily to a decrease in employee-related
and travel expenses as a result of reductions in sales and marketing headcount
throughout the year.

  RESEARCH AND DEVELOPMENT

    Research and development expenses consist primarily of the cost of research
and development personnel and independent contractors, certain licensed
technology and equipment and facilities costs related to such activities.

    In 1999, research and development expenses decreased $3,464 compared to
1998. The decrease was attributable to reductions of $2,745 in employee-related
expenses and of $719 in outside consulting expenses. This reduction in research
and development headcount primarily resulted from the completion of our modular
version of Transact that was released in the first quarter of 1998.

    In 1998, research and development expenses decreased $2,397 compared to 1997
as a result of a reduction in both employee-related expense and the use of
outside technical consultants after completion of a number of technical projects
during the year. In addition, we implemented headcount reductions and

                                       20
<PAGE>
realized other cost efficiencies from the consolidation of the research and
development activities from the Waypoint, Folio and ICentral acquisitions.

    Although research and development expenses have decreased in prior years, we
believe that we will continue to devote substantial resources to our product
development activities and that our expense levels, in absolute dollars, will
increase slightly over the next year.

  GENERAL AND ADMINISTRATIVE

    General and administrative expenses consist primarily of the cost of
finance, management and administrative personnel and legal and other
professional fees.

    In 1999, general and administrative expenses decreased $2,429 from 1998. The
decrease was attributable primarily to a decrease of $1,200 in bad debt expense
and decreases related to travel expenses, professional fees and equipment
rental.

    General and administrative expenses in 1998 slightly increased over 1997.

  AMORTIZATION OF INTANGIBLES

    In 1999, amortization of intangibles increased by $381 from 1998, as a
result of recording a full year of amortization costs related to the 1998
ICentral acquisition. Amortization costs increased by $1,655 in 1998, as a
result of recording a full year of amortization costs related to the 1997 Folio
and Mission Critical Technologies acquisitions.

  ACQUIRED IN-PROCESS RESEARCH AND DEVELOPMENT

    Acquired in-process research and development expenses consisted of $5,700
relating to the ICentral acquisition in 1998, and $429, $9,250 and $25,000
relating to the acquisitions of Mission Critical Technologies, Waypoint and
Folio, respectively, in 1997. These costs were expensed in the periods of the
acquisitions and are included in the accompanying consolidated statements of
operations for the respective periods. The amount allocated to acquired
in-process research and development related to projects that had not yet reached
technological feasibility and that, until completion of development, had no
alternative future use.

  RESTRUCTURING CHARGE

    In the fourth quarter of 1998, we recorded a $2,042 restructuring charge to
align our operating costs with our anticipated future revenue stream. The major
components of the restructuring charge were employee severance, benefits and
related costs, write-off of assets and termination of certain contractual
obligations.

  MERGER RELATED COSTS

    We incurred one-time costs related to our merger with FutureTense of $4,328.
These costs consisted of professional fees and other charges of $3,353 and costs
to exit contractual obligations and asset impairments of $975.

NON-OPERATING INCOME (EXPENSE)

    Interest income represents interest earned on cash, cash equivalents and
marketable securities. The decreases in interest income in 1999 and 1998, as
compared to the prior years, were attributable primarily to lower average
investments in cash, cash equivalents and marketable securities as a result of
increased funding of operations and capital expenditures. Interest expense
relates to the interest charged on our line-of-credit and long-term obligations.
Interest expense increased in 1998 primarily due to the issuance of a $10,000
promissory note in connection with the Folio acquisition in 1997. Interest
expense decreased in

                                       21
<PAGE>
1999 due mainly to the repayment of the promissory note. Other income/expense
primarily represents foreign currency translation gains and losses. In 1998, we
also recorded a loss of approximately $197 on an equity investment.

PROVISION FOR INCOME TAXES

    We recorded a provision for foreign income taxes of $414, $325 and $584 in
1999, 1998 and 1997, respectively. This provision relates to the amount of
estimated taxes due in foreign jurisdictions for our foreign operations and
certain withholding taxes. We incurred losses for U.S. tax purposes for all
periods to date and, accordingly, there has been no provision for U.S. income
taxes. We believe that the provision for income taxes will fluctuate in the
future and is dependent upon the geographical locations of future sales and the
associated withholding taxes in those countries. The provision for income taxes
will also fluctuate when we become eligible for corporate income taxation in the
United States.

LIQUIDITY AND CAPITAL RESOURCES

    At December 31, 1999, we had $32,291 in cash, cash equivalents and
marketable securities, a decrease of $4,428 from December 31, 1998.

    Our operating activities used cash and cash equivalents of $7,978, $32,996
and $32,676 during 1999, 1998 and 1997, respectively, to fund our operations. In
1999, our net loss decreased approximately 46% to $19,780 from $36,970 in 1998.
Accounts receivable decreased in absolute dollars despite a growth in revenues,
primarily as a result of the receipt of cash from revenue recorded in prior
periods with extended terms as well as shorter average payment terms in new
contracts.

    In 1999, our investing activities provided cash and cash equivalents of $51.
The primary source of cash from investing activities in 1999 was $1,973 related
to the maturity of marketable securities, offset by the purchase of property and
equipment in the amount of $2,068. In 1998 and 1997, we used cash and cash
equivalents of $11,397 and $7,729, respectively. In 1998, the principal uses of
cash were $5,933 for purchases related to certain property and equipment and
$5,521 for the purchase of marketable securities. In 1997, the principal uses of
cash from investing activities were $11,400 related to the Folio acquisition and
the purchase of property and equipment in the amount of $7,280, offset by the
maturities of marketable securities worth $11,296.

    Our financing activities provided cash and cash equivalents of $5,510,
$46,124 and $7,236, during 1999, 1998 and 1997, respectively. In 1999, cash and
cash equivalents provided by financing activities consisted of $4,500 related to
the sale of redeemable preferred stock and $7,369 from the issuance of common
stock under our stock option and stock purchase plans. These were offset by the
repayment of a $5,000 note payable in connection with the Folio acquisition. In
1998, we received proceeds of $5,000 from Intel and $20,000 from CMG Information
Services, Inc., and Capital Ventures International from the issuance of common
stock. In addition, we received proceeds of $8,496 from the issuance of
redeemable convertible preferred stock and $4,595 from the issuance of common
stock under our stock option and stock purchase plans. Also in 1998, we repaid
$5,000 of the note payable issued in connection with the Folio acquisition with
a cash payment of $1,818 and an issuance of our common stock having a value of
$3,182. In 1997, the principal source of cash provided by financing activities
was net borrowings of $5,168 against our line of credit.

    In July 1998, we obtained a $2,800 mortgage loan, on a Provo, Utah,
building, which bears interest at the fixed rate of 8.5%. The mortgage principal
payments are based upon a 20-year term with a balloon payment of $2,468 due on
June 19, 2003.

    We have an unsecured credit facility arrangement with a bank which provides
up to $15,000 in financing in the form of a demand line of credit. Borrowings
under this line are limited to 80% of eligible domestic accounts receivable and
90% of eligible foreign accounts receivable, as defined, and bear interest

                                       22
<PAGE>
at the prime lending rate, which was 8.5% at December 31, 1999. We are required
to comply with certain restrictive covenants under this agreement and the line
is collateralized by our accounts receivable. We were in compliance with all
such covenants at December 31, 1999. During 1999, we decreased our borrowings
under this facility to $10,350.

    At December 31, 1999, we had net operating loss carryforwards for income tax
purposes of approximately $119,000. These losses are available to reduce federal
and state taxable income, if any, in future years. These losses are subject to
review and possible adjustment by the Internal Revenue Service and may be
limited in the event of certain cumulative changes in ownership interests of
significant shareholders over a three-year period that are in excess of 50%.
While we believe that we have experienced a change in ownership in excess of
50%, we do not believe that this change in ownership will significantly impact
our ability to use our net operating loss carryforwards.

    We believe that our existing capital resources are adequate to meet our cash
requirements for at least the next 12 months. There can be no assurance,
however, that changes in our plans or other events affecting our operations will
not result in accelerated or unexpected expenditures.

EURO CURRENCY

    On January 1, 1999, certain member countries of the European Union (EU)
established fixed conversion rates between their existing currencies and the
EU's common currency, the euro. The former currencies of the participating
countries are scheduled to remain legal tender as denominations of the euro
until January 1, 2002, when the euro will be adopted as the sole legal currency.

    We continue to assess the impact that the conversion to the euro will have
on our European operations. We are evaluating the potential impact in several
areas of our business, including the ability of our information systems to
handle euro-denominated transactions and the impact on exchange costs and
currency exchange rate risks. We are also evaluating the impact that
cross-border price transparencies, which may affect the ability to price
products differently in various countries, will have on our gross margin.
Although we are still in the assessment phase, the conversion to the euro is not
expected to have a material impact on our operations or financial position.

YEAR 2000 IMPACT

    We have not experienced any significant problems with our computer systems
or software products relating to distinguishing twenty-first century dates from
twentieth century dates, generally referred to as Year 2000 problems. We are
also not aware of any material Year 2000 problems with our clients or vendors.
Accordingly, we do not anticipate incurring material expenses or experiencing
any material operational disruptions as a result of Year 2000 problems.

                                       23

CERTAIN FACTORS THAT MAY AFFECT FUTURE RESULTS
INTRODUCTION

    This Annual Report contains certain forward-looking statements. For this
purpose, any statements we have used that are not statements of historical fact
may be considered forward-looking statements. We have used "believes",
"anticipates", "plans", "expects", and similar expressions. There are a number
of important factors that could cause our actual results to differ materially
from those indicated by forward-looking statements made in this Annual Report
and those presented elsewhere by management from time to time. Some of the
important risks and uncertainties that may cause our operating results to differ
materially or adversely are discussed below.

WE HAVE A HISTORY OF SIGNIFICANT LOSSES AND THESE LOSSES MAY CONTINUE IN THE
FUTURE, WHICH COULD CAUSE THE MARKET PRICE OF OUR COMMON STOCK TO DECLINE

    We have experienced operating losses in each quarterly and annual period
since our inception and these operating losses may continue in the future. We
incurred net losses of $62.5 million for the year ended December 31, 1997,
$37.0 million for the year ended December 31, 1998, and $19.8 million for the
year ended December 31, 1999. As of December 31, 1999, our accumulated deficit
was $164.5 million. We expect to continue to make significant investments to
broaden the range of our product offerings and expand our sales and marketing
and technical personnel. These efforts will require significant capital
expenditures, a substantial portion of which we will make long before any
corresponding revenue may be realized. We may never achieve profitability, and
if we do achieve profitability in any period, we may not be able to sustain or
increase profitability on a quarterly or annual basis.

OUR OPERATING RESULTS ARE LARGELY DEPENDENT UPON THE CONTINUED DEVELOPMENT AND
GROWTH OF INTERNET COMMERCE

    The market for our Internet products and services has only recently begun to
develop, is rapidly evolving and has an increasing number of market entrants
that have introduced and developed products and services for Internet commerce
that compete with ours. Our future operating results depend upon the development
and growth of the market for Internet-based packaged software applications,
including electronic commerce applications. The widespread acceptance of the
Internet as a sales, marketing, order receipt and processing medium is highly
uncertain and subject to a number of risks. The following critical issues remain
unresolved and may impact the growth of Internet commerce:

    - security;

    - reliability;

    - ease of use;

    - service; and

    - government regulation.

    If the Internet commerce market fails to continue to develop or develops
more slowly than expected, our business and prospects will suffer.

THE SALES CYCLE FOR OUR PRODUCTS IS LENGTHY AND MAKES QUARTERLY RESULTS
  DIFFICULT TO PREDICT

    The licensing of our products generally involves a significant commitment of
resources by our prospective customers and we are often required to provide a
significant level of education to them regarding the use and benefits of our
products. This process can be time consuming. The lengthy delays associated with
the sales cycle affect the timing of our revenue recognition and make it
difficult to predict

                                       24
<PAGE>
our quarterly results. If our operating results fall below the expectations of
securities analysts or investors in some future quarter or quarters, the market
price of our common stock could be negatively affected.

IF WE FAIL TO MAINTAIN AND STRENGTHEN OUR RELATIONSHIPS WITH SYSTEMS
  INTEGRATORS, WE MAY NOT ACHIEVE EXPECTED REVENUE GROWTH

    Our prospective customers often rely on third-party systems integrators to
develop, deploy and manage their integrated e-business solutions. A substantial
portion of our revenues are influenced by systems integrators that either
incorporate our products into their solution for the prospective customer or
otherwise recommend our product as an independent solution. If a significant
number of these systems integrators adopt a different product or technology as
part of their integrated solution instead of our products, we may not achieve
expected revenue growth. We cannot assure you that that our efforts to continue
to expand indirect sales in this manner will be successful. In addition, we
cannot be sure that such systems integrators will be able to successfully
support our products within their overall solutions, and our revenues may vary
depending on their ability to offer such support.

IF LIMITATIONS ON THE ONLINE COLLECTION OF PROFILE INFORMATION ARE IMPOSED, THE
  UTILITY OF THE PERSONALIZATION FUNCTIONALITY OF OUR PRODUCTS WOULD BE LIMITED
  AND WE MAY NOT ATTRACT A SIGNIFICANT NUMBER OF NEW CUSTOMERS

    One of the principal features of our products is the ability to develop and
maintain profiles of online users to assist business managers in personalizing
content and commercial offers to be displayed to specific online users. The
resistance of online users to providing personal data and any future laws and
regulations prohibiting use of personal data gathered online without express
consent or requiring businesses to notify their Web site visitors of the
possible dissemination of their personal data could limit the utility of our
products. These types of laws or regulations could heighten privacy concerns by
requiring businesses to notify Web site users that the data captured from them
online may be used by marketing entities to direct product messages to them.
While we are not aware of any laws or regulations of this type currently in
effect or in development in the United States, other countries and political
entities, including the European Union and its member states, have adopted legal
requirements imposing restrictions on the collection, use and processing of
personal data. It is possible that similar legal requirements could be adopted
in the United States. If the privacy concerns of consumers are not adequately
addressed, the effectiveness of our products could be impaired and we may not
attract new customers and the revenues they represent.

IF OUR PRODUCTS FAIL TO ADEQUATELY SAFEGUARD THE SECURITY AND PRIVACY OF
  CUSTOMER TRANSACTION DATA, OUR REPUTATION COULD BE DAMAGED, AND WE COULD LOSE
  EXISTING AND PROSPECTIVE CUSTOMERS AND EXISTING AND POTENTIAL REVENUES

    A significant barrier to electronic commerce and communications has been the
ability to securely transmit confidential information over the Internet. The
concerns over the security of transactions conducted on the Internet and the
privacy of users may inhibit the growth of the Internet generally, and
electronic commerce in particular. In addition, Internet usage could decline if
any well-publicized compromise of security occurred. We may be required to
expend significant capital and other resources to develop products that
adequately protect our customers against such security breaches or to alleviate
problems caused by such breaches. We rely on certain encryption and
authentication technology to provide secure transmission of confidential
information. We cannot assure you that advances in computer capabilities, new
discoveries in the field of cryptography or other events or developments will
not result in a compromise or breach of the algorithms we use to protect
customer transaction data. If any compromise or breach were to occur, it could
damage our reputation and cause us to lose existing and prospective customers.

                                       25
<PAGE>
IF WE DO NOT COMPETE EFFECTIVELY, PARTICULARLY AGAINST ESTABLISHED PARTICIPANTS
  WITH GREATER FINANCIAL AND OTHER RESOURCES THAN OURS, WE WILL LOSE MARKET
  SHARE

    The market for e-business applications is relatively new, rapidly evolving
and intensely competitive. If we fail to compete successfully with current or
future competitors, we may lose market share. Our customers' requirements and
the technology available to satisfy those requirements continually change. We
expect competition in this market to persist and increase in the future. Our
primary competition includes in-house development efforts by prospective
customers and other vendors of application software or application development
platforms and tools directed at interactive commerce and financial services,
such as Art Technology Group, BroadVision, InterShop, InterWorld, Interwoven and
Vignette.

    In addition, larger companies with much broader product offerings, such as
IBM, Microsoft and Oracle, may bundle their products to discourage users from
purchasing our products. Some of our current and potential competitors have
longer operating histories, greater name recognition, larger installed customer
bases and significantly greater financial, technical and marketing resources
than we do. As a result, these competitors may be able to develop and expand
their product offerings more quickly, adapt more swiftly to new or emerging
technology and changes in customer demands, develop greater resources to the
marketing and sales of their product, pursue acquisition and other opportunities
more readily and adapt more aggressive pricing policies. In addition,
competitors have established and, in the future, may establish cooperative
relationships among themselves or with third parties to market or enhance their
products. Accordingly, it is possible that new competitors or alliances among
competitors may emerge and rapidly acquire significant market share. Competitive
pressures may make it difficult for us to acquire and retain customers and are
likely to result in price reductions reduced gross margins and loss of market
share.

OUR ABILITY TO DEVELOP, MARKET AND SUPPORT OUR SERVICES DEPENDS ON RETAINING OUR
  KEY SENIOR MANAGEMENT TEAM AND ATTRACTING AND RETAINING HIGHLY-QUALIFIED
  INDIVIDUALS IN THE INTERNET INDUSTRY

    Our future success depends in significant part upon the continued service of
our key technical and senior management personnel and their continuing ability
to attract and retain highly qualified technical, sales and managerial personnel
in a highly competitive market. Our ability to establish and maintain a position
of technology leadership in the e-business software market depends in large part
upon the skills of our development personnel. Our future success also depends on
our continuing to attract, retain and motivate highly skilled employees.
Competition for employees in our industry is intense. We may be unable to retain
our key employees or attract, assimilate or retain other highly qualified
employees in the future. We have from time to time in the past experienced, and
we expect to continue to experience in the future, difficulty in hiring and
retaining highly skilled employees with appropriate qualifications.

    In connection with our recent acquisition of FutureTense, the founders and
employees of that company received a substantial number of our shares of common
stock and can sell these shares at substantial gains. In many cases, these
individuals could become financially independent through these sales, before the
products of either company have fully matured into commercially deliverable
products commanding reasonable market share. Additionally, start-up and other
companies will seek out these individuals due to the financial results they
achieved for their investors. Under the circumstances, we face a difficult and
significant task of motivating key personnel to stay committed to us.

FLUCTUATIONS IN OUR QUARTERLY REVENUE AND OPERATING RESULTS MAY RESULT IN
  REDUCED PROFITABILITY AND CAUSE THE PRICE OF OUR COMMON STOCK TO DECLINE

    We have experienced significant fluctuations in our results of operations on
a quarterly and annual basis. We expect to continue experiencing significant
fluctuations in our future quarterly and annual results of operations due to a
variety of factors, many of which are outside our control, including:

    - the introduction of new products by us and our competitors;

                                       26
<PAGE>
    - the variability and length of sales cycles associated with our product
      offerings;

    - the market acceptance of, and demand for, our products;

    - the pace of development of electronic commerce conducted on the Internet;

    - customer order deferrals in anticipation of enhancements or new products
      offered by us or our competitors;

    - non-renewal of service agreements;

    - software defects and other product quality problems;

    - the mix of products and services we sell;

    - customer retention;

    - the ability to collect payments from our customers on a timely basis;

    - any changes in our pricing policies and/or those of our competitors;

    - changes in the level of operating expenses; and

    - general economic conditions.

    In addition, our operating expenses are largely based on anticipated revenue
trends and a significant portion of our expenses, such as leased real estate
facilities, depreciation and personnel, is fixed in the short term. Accordingly,
our results of operations are particularly sensitive to fluctuations in
revenues. If our revenues fall below our expectations, we would probably not be
able to reduce our fixed or other expenses in sufficient time to respond to the
shortfall. If our operating results fall below the expectations of securities
analysts or investors in some future quarter or quarters, the market price of
our common stock is likely to decline.

IF WE ARE UNABLE TO MANAGE OUR PLANNED RAPID EXPANSION EFFECTIVELY, WE MAY INCUR
  INCREASED COSTS AND PLACE TOO MANY DEMANDS UPON OUR SENIOR MANAGEMENT TEAM

    We have experienced significant growth over the past two years and we are
pursuing a business plan that, if successfully implemented, will cause us to
continue to expand rapidly over the next several years. This expansion would
occur both domestically and internationally, which would increase our operating
complexity significantly. Our expansion would also require significant time
commitments from our senior management team and severely restrict its ability to
manage our existing business. Our success depends on our ability to manage this
expansion and these demands effectively. We will, among many other things, need
to:

    - improve our business development capabilities;

    - hire, train and manage an increasing number of highly-skilled employees;
      and

    - continually enhance our information, management and operational and
      financial systems.

    Our failure to manage our expansion effectively could increase our costs,
adversely affect our relations with customers and strategic partners and
adversely affect our revenues and operating margins.

WE ARE SUSCEPTIBLE TO NUMEROUS RISKS ASSOCIATED WITH INTERNATIONAL OPERATIONS

    Our international activities expose us to numerous additional risks. In the
year ended December 31, 1999, we derived approximately 29% of our total revenues
from sales outside North America. We currently have seven offices in Europe and
Asia. A key component of our business strategy is to expand our

                                       27
<PAGE>
international activities. As we continue to expand internationally, we are
increasingly subject to risks of doing business internationally, including the
following:

    - unexpected changes in regulatory requirements;

    - export controls relating to encryption technology and other export
      restrictions;

    - tariffs and other trade barriers;

    - difficulties in staffing and managing foreign operations;

    - political and economic instability;

    - fluctuations in currency exchange rates;

    - reduced protection for intellectual property rights;

    - cultural barriers;

    - difficulty of enforcing agreements and collecting accounts receivables;

    - seasonal reductions in business activity during the summer months in
      Europe and certain other parts of the world; and

    - potentially adverse tax consequences.

    Our international sales growth will be limited if we are unable to establish
additional foreign operations, expand international sales channel management and
support, hire additional personnel, customize products for local markets and
develop relationships with international distributors and systems integrators.
Even if we are able to successfully expand our international operations, we
cannot be certain that we will succeed in maintaining or expanding international
market demand for our products.

WE MAY NOT BE ABLE TO PROTECT OUR PROPRIETARY RIGHTS AND WE MAY BE SUBJECT TO
  INFRINGEMENT CLAIMS THAT COULD SUBJECT US TO SIGNIFICANT LIABILITY AND DIVERT
  THE TIME AND ATTENTION OF OUR SENIOR MANAGEMENT

    We regard our products, services and technology as proprietary. We attempt
to protect them through a combination of patents, copyrights, trademarks and
trade secret laws. We also generally enter into confidentiality agreements with
our employees, consultants and customers, and generally control access to and
distribution of our documentation and other proprietary information. These
methods may not be sufficient to protect our proprietary rights. We have no
patented technology that would preclude or inhibit competitors from entering our
market. Although we hold several U.S. patents asserting claims relating to
certain aspects or uses of electronic commerce software, we cannot be sure of
the degree of intellectual property protection those patents will provide.
Despite these precautions, it may be possible for a third party to copy or
otherwise misappropriate and use our products, services or technology without
authorization, particularly in foreign countries where the laws may not protect
our proprietary rights to the same extent as do the laws of the United States.
We also cannot assure you that third parties will not develop similar technology
independently. We may need to resort to litigation in the future to enforce our
intellectual property rights, to protect our trade secrets or to determine the
validity and scope of the proprietary rights of others. This litigation could
result in substantial costs and diversion of resources and could harm our
business.

    In addition to licensing technologies from third parties, we are developing
and acquiring additional proprietary intellectual property. Third parties may
try to claim our products or services infringe their intellectual property. We
expect that participants in our markets will be increasingly subject to
infringement claims. Any claim, whether meritorious or not, could be time
consuming, result in costly litigation and/or require us to enter into royalty
or licensing agreements. These royalty or licensing agreements might not be
available on terms acceptable to us or at all, in which case we would have to
cease selling,

                                       28
<PAGE>
incorporating or using those products and services that incorporate the
challenged intellectual property and expend substantial amounts of resources to
redesign our products or services. If we are forced to enter into royalty or
licensing agreements or to redesign our products or services, our business and
prospects would suffer.

WE ARE DEPENDENT ON THIRD PARTY TECHNOLOGY AND IF WE ARE UNABLE TO LICENSE THIS
  TECHNOLOGY, OR IF DEFECTS IN THIS TECHNOLOGY EXIST, OUR PRODUCT SHIPMENTS
  COULD BE DELAYED

    We rely in large part on technology that we license from third parties,
including relational database management systems from Oracle and application
server software from Netscape. The licenses from these third parties may not
continue to be available to us on commercially reasonable terms, or at all. If
we were to lose any of these technology licenses, we would have to cease selling
our products that incorporate the licensed technology and expend substantial
amounts of resources to redesign our products using equivalent technology, if
available. If we are forced to cease selling and to redesign our products, our
business and prospects would suffer.

OUR PRODUCTS MAY CONTAIN DEFECTS WHICH MAY PROVE COSTLY AND TIME CONSUMING FOR
  US TO CORRECT

    Sophisticated software products, such as those we develop and market, may
contain errors or failures that become apparent when we introduce the products
or when we provide an increased volume of services. We cannot assure you that
testing by us and our potential customers will detect all errors in our products
prior to licensing or sale. Correcting such errors may result in loss of
revenues, delay in market acceptance, diversion of development resources, damage
to our reputation or increased service and warranty costs, any of which would
adversely affect our business and our ability to market our products profitably.

IF WE DO NOT RESPOND EFFECTIVELY AND ON A TIMELY BASIS TO RAPID TECHNOLOGICAL
  CHANGES AND EVOLVING INDUSTRY STANDARDS, OUR PRODUCTS MAY BECOME OBSOLETE, AND
  WE WOULD PROBABLY LOSE EXISTING CUSTOMERS AND BE UNABLE TO ATTRACT NEW ONES

    Internet markets are characterized by rapidly changing technologies,
evolving industry standards, frequent new product and service introductions and
changing customer demands. The introduction of new products or technologies
could render our product offerings obsolete, reduce the cost of competing
products or increase the number of products similar to those that we provide or
plan to provide. Our future success will depend on our ability to adapt to
rapidly changing technologies and to enhance existing solutions and develop and
introduce a variety of new solutions and services to address our customers'
changing demands. We may be required to make significant and ongoing investments
in future periods in order to remain competitive. Further, we may experience
difficulties that could delay or prevent the successful design, development,
introduction or marketing of our solutions and services or lengthen our sales
cycles. In addition, our new solutions or enhancements must meet the
requirements of our current and prospective customers and must achieve
significant market acceptance. Any material delays in introducing new solutions
and enhancements may cause customers to forego purchases of our solutions and
purchase those of our competitors. Our failure to successfully design, develop,
test and introduce new services, or the failure of our recently introduced
services to achieve market acceptance, could prevent us from maintaining
existing client relationships, gaining new clients or expanding our markets. In
such a case, we would not achieve our expected revenue growth.

IF WE FAIL TO ADEQUATELY INTEGRATE THE OPERATIONS OF FUTURETENSE, WE MAY NOT
  REALIZE THE EXPECTED BENEFITS OF THE MERGER

    We completed our acquisition of FutureTense in October 1999. The integration
of FutureTense is a complex process and we are uncertain that the integration
will be completed rapidly or that we will achieve the anticipated benefits of
the merger. Our successful integration of FutureTense will require, among other

                                       29
<PAGE>
things, integration of the sales and marketing groups of each entity and the
integration of our product lines. The diversion of the attention of management
and any difficulties encountered in the process of combining both companies
could cause the disruption of, or a loss of momentum in, the activities of the
combined business. In addition, the process of combining both companies could
negatively affect our employee morale and our ability to retain some of our key
employees or could cause customers to delay or change orders for products as a
result of uncertainty over the integration of our product lines. We will need to
overcome these issues in order to realize the benefits or synergies of the
merger.

IF WE FAIL TO SUCCESSFULLY CROSS-MARKET OUR PRODUCTS AND FUTURETENSE'S PRODUCTS,
WE MAY NOT INCREASE OR MAINTAIN OUR CUSTOMER BASE OR OUR REVENUES

    We intend to offer the respective products and services historically offered
by us and by FutureTense to our collective customers. FutureTense's customers
may have no interest in our products and services and our customers may have no
interest in theirs. The failure of our cross-marketing efforts may diminish the
benefits we realize from the FutureTense merger. In addition, we intend to
develop new products and services that combine our knowledge and resources with
those of FutureTense. We cannot assure you that these products or services will
be developed or, if developed, will be successful or that we can successfully
integrate or realize the anticipated benefits of the merger. As a result, we may
not be able to increase or maintain our customer base.

THE REGULATION OF THE INTERNET IS UNSETTLED, AND FUTURE REGULATIONS COULD
ADVERSELY AFFECT OUR OPERATING COSTS AND OUR ABILITY TO MARKET PRODUCTS
FACILITATING INTERNET COMMERCE

    The laws and regulations that apply to commerce and communication over the
Internet are becoming more prevalent. Such legislation could dampen the growth
in Internet usage generally and decrease the acceptance of the Internet as a
commercial medium. The United States Congress has recently considered enacting
Internet laws regarding children's privacy, copyrights, taxation and the
transmission of sexually explicit material. The European Union also recently
enacted its own privacy regulations. The laws governing the Internet, however,
remain largely unsettled, even in areas where there has been some legislative
action. It may take years to determine whether and how existing laws such as
those governing intellectual property, telecommunications, privacy, libel and
taxation apply to the Internet. In addition, the growth and development of the
market for electronic commerce may prompt calls for more stringent consumer
protection laws, both in the United States and abroad, that may impose
additional burdens on companies conducting business over the Internet.

EXISTING AND FUTURE EXPORT CONTROLS MAY DELAY THE INTRODUCTION OF NEW PRODUCTS
OR LIMIT OUR ABILITY TO DISTRIBUTE PRODUCTS OUTSIDE OF THE UNITED STATES

    Due to the encryption technology contained in our products, our products are
subject to export controls within the United States. These export controls,
either in their current form or as may be subsequently enacted, may delay the
introduction of new products or limit our ability to distribute products outside
the United States. In addition, federal or state legislation or regulation may
further limit levels of encryption or authentication technology. Also, various
countries regulate the import of certain encryption technology and have adopted
laws relating to personal privacy issues that could limit our ability to
distribute products in those countries.

OUR BUSINESS MAY SUFFER IF THE INTERNET INFRASTRUCTURE IS UNABLE TO EFFECTIVELY
SUPPORT THE GROWTH IN DEMAND PLACED ON IT

    Our success will depend, in large part, upon the maintenance of the Internet
infrastructure, such as reliable network backbones with the necessary speed,
data capacity and security, and the timely development of enabling products such
as high speed modems, for providing reliable Internet access and services and
improved content. We cannot assure you that the Internet infrastructure will
continue to effectively

                                       30
<PAGE>
support the demands placed on it as the Internet continues to experience
increased numbers of users, frequency of use and increased bandwidth
requirements. Even if the necessary infrastructure or technologies are
developed, we may have to spend considerable amounts to adapt our solutions
accordingly. Furthermore, the Internet has experienced a variety of outages and
other delays due to damage to portions of its infrastructure. These outages and
delays could impact the Internet sites of Web publishers using our products and
services.

THE IMPOSITION OF SALES AND OTHER TAXES ON PRODUCTS SOLD BY OUR CUSTOMERS OVER
  THE INTERNET COULD HAVE A NEGATIVE EFFECT ON ONLINE COMMERCE AND, AS A RESULT,
  ON DEMAND FOR OUR PRODUCTS

    The imposition of new sales or other taxes could limit the growth of
electronic commerce generally and, as a result, the demand for our products.
There is recent federal legislation that limits the imposition of state and
local taxes on Internet-related sales. In 1998, the United States Congress
passed the Internet Tax Freedom Act, which places a three-year moratorium on
state and local taxes on Internet access, unless the tax was already imposed
prior to October 1, 1998, and discriminatory taxes on electronic commerce. There
is a possibility that Congress may not renew this legislation in 2001. If
Congress chooses not to renew this legislation, state and local governments
would be free to impose taxes on goods purchased over the Internet.

    In addition, one or more foreign countries may seek to impose sales or other
tax collection obligations on out-of-jurisdiction companies that engage in
electronic commerce. A successful assertion by one or more foreign countries
that companies engaged in electronic commerce should collect sales or other
taxes on sales of their products over the Internet, even though not physically
present in the foreign country, could indirectly reduce demand for our products.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK

    FOREIGN EXCHANGE HEDGING.  The accounts of Open Market's foreign
subsidiaries are translated in accordance with SFAS No. 52, FOREIGN CURRENCY
TRANSLATION. In translating the accounts of the foreign subsidiaries into U.S.
dollars, assets and liabilities are translated at the rate of exchange in effect
at year-end, while stockholders' equity is translated at historical rates.
Revenue and expense accounts are translated using the weighted average exchange
rate in effect during the year. Foreign currency translation and transaction
gains or losses for our subsidiaries are included in the accompanying
consolidated statements of operations since the functional currency for our
subsidiaries is the U.S. dollar.

    INVESTMENT PORTFOLIO.  We do not use derivative financial instruments for
investment purposes and only invest in financial instruments that meet the high
credit quality standards, as specified in our investment policy guidelines. This
policy also limits the amount of credit exposure of any one issue, issuer, and
type of investment. See "Note 2--Summary of Significant Accounting Policies" in
the accompanying Notes to Consolidated Financial Statements.

QUARTERLY FINANCIAL RESULTS

    The following table sets forth certain unaudited quarterly financial data
for 1998 and 1999. In the opinion of management, the unaudited quarterly
information has been prepared on the same basis as the audited consolidated
financial statements and includes all adjustments, consisting only of normal
recurring adjustments, necessary for the fair presentation of the information
for the periods presented. The quarterly operating results are not necessarily
indicative of results of operations for any future period.

    Our merger with FutureTense in October 1999 was accounted for as a pooling
of interests, and accordingly, all prior period financial data have been
restated as if the merger took place at the beginning of such periods.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To the Board of Directors and Stockholders of Open Market, Inc.:

    We have audited the accompanying consolidated balance sheets of Open
Market, Inc. (a Delaware corporation) and subsidiaries as of December 31, 1999
and 1998, and the related consolidated statements of operations, redeemable
convertible preferred stock and stockholders' equity and cash flows for each of
the three years in the period ended December 31, 1999. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits. We did not audit the 1998 and 1997 financial statements of
FutureTense, Inc., a company acquired during 1999 in a transaction accounted for
as a pooling of interests, as discussed in Note 4(a). Such financial statements
are included in the consolidated financial statements of Open Market, Inc. and
reflect total assets of 4% in 1998 and total revenues of 4% and 0% in 1998 and
1997, respectively. These statements were audited by other auditors whose report
has been furnished to us and our opinion, insofar as it relates to amounts
included for FutureTense, Inc., is based solely upon the report of the other
auditors.

    We conducted our audits in accordance with auditing standards generally
accepted in the United States. Those standards require that we plan and perform
the audit to obtain reasonable assurance about whether the financial statements
are free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements. An
audit also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits and the report of the other
auditors provide a reasonable basis for our opinion.

    In our opinion, based on our audit and the report of the other auditors, the
financial statements referred to above present fairly, in all material respects,
the financial position of Open Market, Inc. and subsidiaries as of December 31,
1999 and 1998, and the results of their operations and their cash flows for each
of the three years in the period ended December 31, 1999, in conformity with
accounting principles generally accepted in the United States.

                       REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Directors and Stockholders of Open Market, Inc:

    In our opinion, the accompanying balance sheets and the related statements
of operations, changes in stockholders' deficit and cash flows present fairly,
in all material respects, the financial position of FutureTense, Inc. at
December 31, 1998, and the results of its operations and its cash flows for each
of the two years in the period ended December 31, 1998 in conformity with
accounting principles generally accepted in the United States. These financial
statements are the responsibility of the Company's management; our
responsibility is to express an opinion on these financial statements based on
our audits. We conducted our audits of these statements in accordance with
auditing standards generally accepted in the United States, which require that
we plan and perform the audit to obtain reasonable assurance about whether the
financial statements are free of material misstatement. An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements, assessing the accounting principles used and
significant estimates made by management, and evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for the opinion expressed above.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                (IN THOUSANDS, EXCEPT SHARE AND PER SHARE DATA)

(1) OPERATIONS

    Open Market, Inc. ("Open Market" or "the Company") offers an integrated
suite of e-business software products and services that enable our customers to
manage and deliver online content, and engage in personalized online marketing.
The integrated e-business application suite is built on an open standards-based
architecture that is scalable and easily adaptable to the evolving business
through a broad range of media, including Web browsers and cell phones, personal
digital assistants and other wireless devices. The Company currently offers
three principal products: Internet Publishing System, the integrated publishing
system that provides content management and dynamic delivery of personalized
information: Transact, our comprehensive order management and transaction
processing system: and Shopsite, our web storefront building software for small
to medium businesses.

    The Company is subject to risks common to growing technology-based
companies, including a history of significant losses, operating results are
largely dependent upon continued development and growth of Internet commerce,
lengthy sales cycles, dependence on systems integrators, competition,
fluctuations in quarterly operating results, managing rapid expansion,
international operations, product defects, integration of FutureTense
acquisition, dependence on intellectual property, potential intellectual
property rights infringements and threat of product defects.

(2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

    The accompanying consolidated financial statements reflect the application
of the following significant accounting policies described in this note and
elsewhere in the accompanying notes to consolidated financial statements.

    (A) PRINCIPLES OF CONSOLIDATION

    The accompanying consolidated financial statements include the accounts of
the Company, and its wholly owned subsidiaries, which includes
FutureTense, Inc., for all periods presented. All material intercompany accounts
and transactions have been eliminated in consolidation.

    (B) REVENUE RECOGNITION

    The Company recognizes revenue in accordance with Statement of Position
(SOP) 97-2, SOFTWARE REVENUE RECOGNITION, as amended by SOP 98-4. Additionally,
the American Institute of Certified Public Accountants recently issued SOP 98-9,
which provides for certain amendments to SOP 97-2, which is effective for
transactions entered into beginning January 1, 2000. This pronouncement is not
expected to materially impact the Company's revenue recognition practices. The
Company generates revenues from two sources: license fees for the use of our
products and service revenues for implementation, support, consulting and
training related to our products.

    The Company executes separate contracts that govern the terms and conditions
of each software license and maintenance arrangement and each professional
services arrangement. These contracts may be an element in a multiple element
arrangement. Revenues under multiple element arrangements, which may include
several different software products or services sold together, are allocated to
each element based on the residual method in accordance with Statement of
Position 98-9, SOFTWARE REVENUE RECOGNITION, WITH RESPECT TO CERTAIN
ARRANGEMENTS.

    The Company uses the residual method when fair value does not exist for one
of the delivered elements in an arrangement. Under the residual method, the fair
value of the undelivered elements is

                (IN THOUSANDS, EXCEPT SHARE AND PER SHARE DATA)

(2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
deferred and subsequently recognized. The Company has established sufficient
vendor specific objective evidence for the value of professional services,
training and maintenance and support services based on the price charged when
these elements are sold separately. Accordingly, software license revenue is
recognized under the residual method in arrangements in which software is
licensed with professional services, training and maintenance and support
services.

    Revenues from software license agreements are recognized upon delivery of
the software if there is evidence of an agreement, there are no significant
post-delivery obligations, and the payment is fixed or determinable and
collection is probable. If an acceptance period is required, revenues are
recognized upon customer acceptance. The Company enters into reseller
arrangements for certain products that typically provide for sublicense fees
payable to the Company based on a percentage of the Company's list price.
Royalty and sublicense revenues from the Company's reseller arrangements are
recognized when earned, either on a per-unit basis as reported to the Company by
its licensees, or, with regards to guaranteed minimums, upon shipment of the
master copy of all software to which the guaranteed minimum sublicense fees
relate, if there are no significant post-delivery obligations. Revenues for
post-contract customer support are recognized ratably over the term of the
support period, which is typically one year. Service revenues, which includes
education, implementation and consulting services, are recognized in the period
services are provided, if customer acceptance is not required, there is evidence
of an agreement, the revenues are fixed or determinable and collection is
probable.

    Cost of product revenues consists of costs to distribute the product,
including the cost of the media on which it is delivered and royalty payments to
third-party vendors. Cost of service revenues consists primarily of consulting
and support personnel salaries and related costs.

    Deferred revenues represent cash received from customers for products and
services in advance of revenue recognition.

    (C) CASH, CASH EQUIVALENTS AND MARKETABLE SECURITIES

    The Company accounts for investments under Statement of Financial Accounting
Standards (SFAS) No. 115, ACCOUNTING FOR CERTAIN INVESTMENTS IN DEBT AND EQUITY
SECURITIES. Under SFAS No. 115, investments for which the Company has the
positive intent and ability to hold to maturity, consisting of cash equivalents
and marketable securities, are reported at amortized cost, which approximates
fair market value. Cash equivalents are highly liquid investments with original
maturities of less than three months. Marketable securities are investment-grade
securities with original maturities of greater than three months. The average
maturity of the Company's marketable securities was approximately five months at
December 31,

    (E) RESEARCH AND DEVELOPMENT EXPENSES

    The Company has evaluated the establishment of technological feasibility of
its products in accordance with SFAS No. 86, ACCOUNTING FOR THE COSTS OF
COMPUTER SOFTWARE TO BE SOLD, LEASED OR OTHERWISE MARKETED. The Company sells
products in a market that is subject to rapid technological change, new product
development and changing customer needs; accordingly, the Company has concluded
that technological feasibility is not established until the development stage of
the product is nearly complete. The Company defines technological feasibility as
the completion of a working model. The time period during which costs could be
capitalized, from the point of reaching technological feasibility until the time
of general product release, is very short, and consequently, the amounts that
could be capitalized are not material to the Company's financial position or
results of operations. Therefore, the Company has charged all such costs to
research and development in the period incurred.

(2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    (F) TRANSLATION OF FOREIGN CURRENCIES

    The accounts of the Company's foreign subsidiaries are translated in
accordance with SFAS No. 52, FOREIGN CURRENCY TRANSLATION. In translating the
accounts of the foreign subsidiaries into U.S. dollars, assets and liabilities
are translated at the rate of exchange in effect at year-end, while
stockholders' equity is translated at historical rates. Revenue and expense
accounts are translated using the weighted average rate in effect during the
year. Foreign currency translation and transaction gains or losses for the
foreign subsidiary are included in the accompanying consolidated statements of
operations since the functional currency of these subsidiaries is the U.S.
dollar. The Company had accounts receivable of approximately $1,036 and $944
denominated in foreign currencies as of December 31, 1999 and 1998,
respectively. The Company marks these receivables to market and records a gain
or loss, which is a component of other income/expense in the consolidated
statements of operations. The Company has not incurred a significant loss to
date.

    (G) NET LOSS PER SHARE

    The Company applies SFAS No. 128, EARNINGS PER SHARE. SFAS No. 128
establishes standards for computing and presenting earnings per share and
applies to entities with publicly held common stock or potential common stock.
The Company has applied the provisions of SFAS No. 128 and Staff Accounting
Bulletin (SAB) No. 98 for all periods presented. Net loss per share is based
upon the weighted average outstanding shares of common stock, adjusted to give
effect to the number of equivalent shares of Open Market common stock issued in
connection with the FutureTense acquisition for all periods presented. Diluted
net loss per share for the years ended 1999, 1998 and 1997 is the same as basic
net loss per share as the inclusion of the potential common stock equivalents
would be antidilutive. The number of outstanding antidilutive potential common
stock, consist of warrants, shares held in escrow from the FutureTense
acquisition and stock options totaling 8,259, 6,622 and 6,741 for the years
ended December 31, 1999, 1998 and 1997, respectively.

    (H) CONCENTRATIONS OF CREDIT RISK

    SFAS No. 105, DISCLOSURE OF INFORMATION ABOUT FINANCIAL INSTRUMENTS WITH
OFF-BALANCE-SHEET RISK AND FINANCIAL INSTRUMENTS WITH CONCENTRATIONS OF CREDIT
RISK, requires disclosure of any significant off-balance-sheet risk and credit
risk concentrations. The Company has no significant off-balance-sheet risk or
credit risk concentrations. The Company maintains its cash and cash equivalents
with several financial institutions and invests in investment-grade securities.
The Company did not have any customers with revenues greater than 10% of total
revenues in the years ended December 31, 1999, 1998 and 1997 or accounts
receivable balances greater than 10% of total accounts receivable as of
December 31, 1999 and 1998.

    (I) POSTRETIREMENT BENEFITS

    The Company has no obligations for postretirement benefits.

    (J) FINANCIAL INSTRUMENTS

    The estimated fair values of the Company's financial instruments, which
include cash equivalents, marketable securities, accounts receivable, accounts
payable, line of credit, long-term debt and obligations and redeemable
convertible preferred stock approximate their carrying value.

    (K) USE OF ESTIMATES

    The preparation of the accompanying consolidated financial statements
required the use of certain estimates by management in determining the Company's
assets, liabilities, revenues and expenses. Actual results could differ from
those estimates.

    (L) RECLASSIFICATIONS

    The Company has reclassified certain prior year information to conform with
current year's presentation.

    (M) COMPREHENSIVE LOSS

    SFAS No. 130, REPORTING COMPREHENSIVE INCOME, requires disclosure of all
components of comprehensive loss on an annual and interim basis. Comprehensive
loss is defined as the change in equity of a business enterprise during a period
from transactions and other events and circumstances from nonowner sources. The
Company's comprehensive loss is the same as the reported net loss for all
periods presented.

    (N) DISCLOSURES ABOUT SEGMENTS OF AN ENTERPRISE

    The Company applies SFAS No. 131, DISCLOSURES ABOUT SEGMENTS OF AN
ENTERPRISE AND RELATED INFORMATION which establishes standards for reporting
information regarding operating segments in annual financial statements and
requires selected information for those segments to be presented in interim
financial reports issued to stockholders. SFAS No. 131 also establishes
standards for related disclosures about products and services and geographic
areas. Operating segments are identified as components of an enterprise about
which separate discrete financial information is available for evaluation by the
chief operating decision maker, or decision making group, in making decisions on
how to allocate resources and assess performance. The Company's chief
decision-maker, as defined under SFAS No. 131, is a combination of the Chief
Executive Officer and the Chief Financial Officer.

    The Company has three reportable operating segments (1) commerce management,
including the licensing of Transact, LiveCommerce and ShopSite products,
(2) content management, including the licensing of Internet Publishing System
and (3) other, which includes the publishing product suite and

</TABLE>

    All of the Company's product sales for the years ended December 31, 1999,
1998 and 1997 were shipped from its facilities located in the United States. As
of December 31, 1999 and 1998 all of the Company's assets relate to the
e-business segment, except for $10,173 and $25,439, respectively which are
attributable to the other product revenue segment. Substantially, all of the
Company's long lived assets are located in the United States.

    (O) LONG-LIVED ASSETS

    The Company evaluates the carrying value of long-lived assets based on the
guidance in SFAS No. 121, ACCOUNTING FOR THE IMPAIRMENT OF LONG-LIVED ASSETS AND
FOR LONG-LIVED ASSETS TO BE DISPOSED OF. The

                (IN THOUSANDS, EXCEPT SHARE AND PER SHARE DATA)

(2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
Company's evaluation considers strategy, competitive information, market trends
and operating performance. Based on its evaluation at December 31, 1999, the
Company does not believe any impairment of long-lived assets exists.

    (P) NEW ACCOUNTING STANDARDS

    The Securities and Exchange Commission issued SAB No. 101, REVENUE
RECOGNITION, in December 1999. The Company is required to adopt this new
accounting guidance through a cumulative charge to operations, in accordance
with Accounting Principles Board Opinion (APB) No. 20, ACCOUNTING CHANGES, no
later than the second quarter of fiscal 2000. The Company believes that the
adoption of the guidance provided in SAB No. 101 will not have a material impact
on future operating results.

    In June 1998, the Financial Accounting Standards Board (FASB) issued SFAS
No. 133, ACCOUNTING FOR DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES. This
statement establishes accounting and reporting standards for derivative
instruments, including certain derivative instruments embedded in other
contracts, and for hedging activities, SFAS No. 133, as amended by SFAS
No. 137, is effective for all fiscal quarters of fiscal years beginning after
June 15, 2000. SFAS No. 133 is not expected to have a material impact on the
Company's consolidated financial statements.

(3) SPECIAL CHARGES

    (A) RESTRUCTURING CHARGES

    In the fourth quarter of 1998, the Company implemented a restructuring plan
to better align its operating costs with its anticipated future revenue stream.
The major component of the restructuring charge related to the elimination of
approximately 67 employees across the following functions: research and
development (27), marketing (17), general and administrative (22) and services
(1). In addition, 10 employees moved from research and development to services.
Other components related to settling certain contractual arrangements for
porting and product integration that resulted from a change in product strategy.
Other charges included the write-off of unutilized software, originally intended
for use by the sales force but not implemented due to the reduction in marketing
personnel. The total cash impact of the restructuring amounted to approximately
$1,748. All liabilities were paid as of December 31, 1999. Following are the
significant components of the restructuring charge:

(4) ACQUISITIONS

    (A) FUTURETENSE, INC.

    Effective October 15, 1999, Open Market, Inc. completed a merger with
FutureTense, Inc., (FutureTense) a software internet content management and
delivery company. The Company issued 7,346,210 shares of its common stock to the
holders of outstanding FutureTense stock, and of this total, 734,621 shares were
placed in escrow. Each FutureTense share was exchanged for .384 shares of Open
Market common stock. In addition, the Company assumed FutureTense employee stock
options and warrants that converted into options to acquire 1,124,628 shares of
Open Market stock. As of the date of the consumation of the merger, the common
stock issued by Open Market and the converted options had an aggregate market
value of $111,180. The merger has been accounted for as a pooling of interests
and, accordingly, all prior period financial statements presented herein have
been restated as if the merger took place at the beginning of such periods. In
addition, in connection with this acquisition, the Company entered into
employment agreements in 1999 with key employees of FutureTense.

    During the nine month period ended September 30, 1999, the Company recorded
revenues of $432 related to the sale of FutureTense products and services as
part of a reseller agreement. This amount has been eliminated in consolidation.
No other material adjustments were required as a result of conforming the
accounting policies of FutureTense to the existing Open Market policies.

    In accordance with Accounting Principles Board Opinion (APB) No. 16, the
following information presents statement of operations data for the periods
preceding the merger:

defined. In addition, in connection with this acquisition, the Company entered
into employment agreements in 1998 with certain key employees of ICentral under
which the Company agreed to pay bonuses in an aggregate amount of $1,000,
depending on certain future events, as defined. The employees earned $609 under
the employment agreements, which was paid through the issuance of 48,752 shares
of common stock under the Company's 1994 Stock Purchase Plan. The remainder was
forfeited due to termination of employment. For financial statement purposes,
this acquisition was accounted for as a purchase, and accordingly, the results
of operations of ICentral subsequent to April 30, 1998 are included in the
Company's consolidated statements of operations.

    The aggregate purchase price of $12,086 consisted of the following:

    The purchase price was allocated based upon the fair value of the tangible
and intangible assets acquired. These allocations represent the fair values
determined by an appraisal. The appraisal incorporated proven valuation
procedures and techniques in determining the fair value of each intangible
asset. The purchase price has been allocated as follows:

</TABLE>

    The in-process research and development has been expensed as a charge
against operations as of the closing of the transaction, and is included in the
accompanying 1998 consolidated statement of operations. The amount allocated to
in-process research and development relates to projects that had not yet reached
technological feasibility and that, until completion of development, have no
alternative future use. These projects were to require substantial development
and testing prior to reaching technological feasibility. However, there could be
no assurance that these projects would reach technological feasibility or
develop into products that would be sold profitably by the Company. The
technology acquired in the acquisition of ICentral has required, and will
continue to require, substantial additional development by the Company. The
capitalized intangible assets are being amortized over five to seven years. The
Company recorded approximately $1,260 and $840 of amortization expense relating
to these intangible assets during 1999 and 1998, respectively.

    (C) WAYPOINT SOFTWARE CORPORATION

    On February 12, 1997, the Company acquired all of the outstanding shares of
capital stock of Waypoint Software Corporation (Waypoint), a software
development company specializing in the business-to-business industrial catalog
segment of the Internet. As payment of the purchase price, the Company issued an
aggregate of approximately 739,000 shares of its common stock to the
stockholders of Waypoint and issued options to acquire approximately 6,000
shares of the Company's common stock at $0.456 per share to Waypoint option
holders. The value of the shares of, and the options to acquire, the Company's
common stock issued in connection with the acquisition was approximately $11,000
based on a weighted average market price, as defined, of the Company's freely
tradable shares. The shares issued were subject to certain selling restrictions
and, as a result, were not freely tradable. Therefore, for purposes of
calculating aggregate consideration paid, the value of the shares issued was
recorded at a discounted value. In addition, in connection with this
acquisition, the Company has entered into employment agreements with certain of
the principals of Waypoint under which the Company has agreed to pay bonuses in
an aggregate amount of $1,200 over two years depending on certain future events,
as defined. The total bonus amounts were paid as of February 1999. For financial
statement purposes, this acquisition was accounted for as a purchase, and
accordingly, the results of operations of Waypoint subsequent to February 12,
1997, are included in the Company's consolidated statements of operations.

    The aggregate purchase price of $9,922 consisted of the following:

projects were to require substantial development and testing prior to the
reaching of technological feasibility. However, there could be no assurance that
these projects would reach technological feasibility or develop into products
that might be sold profitably by the Company. The technology acquired in the
acquisition of Waypoint has required substantial additional development by the
Company which resulted in the first release of the LiveCommerce catalog in
October 1998.

    (D) FOLIO CORPORATION

    Pursuant to a Stock Purchase Agreement dated as of February 20, 1997 (the
"Stock Purchase Agreement"), the Company acquired all of the outstanding shares
of capital stock of Folio Corporation (Folio), a leading supplier of software
for managing business-critical information from Reed Elsevier. As payment of the
purchase price, the Company (i) issued 897,866 shares of common stock of the
Company, (ii) made a cash payment of $10,000, (iii) agreed to issue 897,866
shares of common stock of the Company in January 1998 and (iv) issued a
promissory note of the Company in the original principal amount of $10,000
payable in either cash or a combination of cash and common stock of the Company.
(See Note 6(b)) The value of the shares of common stock of the Company issued or
reserved for issuance was approximately $25,000, based on a weighted average
market price, as defined, of the Company's freely tradable shares. The shares of
common stock issued in March 1997 and in January 1998 were not freely tradable
due to selling restrictions. Therefore, for purposes of calculating the
aggregate consideration paid, the value of such shares was recorded at a
discounted value at the time of issuance. The Stock Purchase Agreement provided
for a purchase price adjustment based on the change in the net assets of Folio
from the estimated value at December 31, 1996, through the date of closing. As a
result of this adjustment, the former stockholder of Folio forfeited 270,116
shares of common stock of the Company to be issued in the transaction.
Additional paid-in capital in the accompanying consolidated statements of
stockholders' equity included the value of the shares to be issued in
January 1998, net of the forfeited shares. The Company repaid $5,000 of the note
payable issued to Reed Elsevier in 1997 in connection with the Folio acquisition
with a $1,818 cash payment and $3,182 of common stock. The Company repaid the
remaining $5,000 note payable in cash in March 1999. For financial statement
purposes, this acquisition was accounted for as a purchase, and accordingly, the
results of operations of Folio subsequent to March 7, 1997, are included in the
Company's consolidated statements of operations. For tax purposes, this
transaction will be treated as a deemed asset purchase in accordance with the
Internal Revenue Code Section 338(h)(10).

    The aggregate purchase price of $45,512 consisted of the following:

    The in-process research and development has been expensed as a charge
against operations as of the closing of the transaction, and is included in the
accompanying 1997 consolidated statement of operations. The amount allocated to
in-process research and development relates to projects that had not yet reached
technological feasibility and that, until completion of development, have no
alternative future use. These projects were to require substantial development
and testing prior to reaching technological feasibility. However, there could be
no assurance that these projects would reach technological feasibility or
develop into products that would be sold profitably by the Company. The
technology acquired in the acquisition of Folio required substantial additional
development by the Company. The capitalized intangible assets are being
amortized over five to seven years. The Company recorded approximately $1,710,
$1,620 and $1,351 of amortization expense relating to these intangible assets
during 1999, 1998 and 1997, respectively. In 1999, the Company entered into an
exclusive worldwide marketing and distribution agreement with NextPage for the
Folio publishing products (see note 11).

    (E) MISSION CRITICAL TECHNOLOGIES

    On October 20, 1997, FutureTense acquired all the outstanding shares of
Mission Critical Technologies ("MCT"). MCT was engaged in the design,
development and distribution of software primarily to the publishing industry.
As payment of the purchase price, FutureTense (i) issued an aggregate of 128,748
shares of FutureTense's Series B redeemable convertible preferred stock valued
at $937 (ii) non-interest bearing note in the amount of $439. For financial
statement purposes, this acquisition was accounted for as a purchase, and
accordingly, the results of operations of MCT subsequent to October 20, 1997,
are included in the Open Market's consolidated statements of operations. The
aggregate purchase price of $2,556 consisted of the following:

    The in-process research and development has been expensed as a charge
against operations as of the closing of the transaction, and is included in the
accompanying 1997 consolidated statement of operations. The amount allocated to
in-process research and development relates to projects that had not yet reached
technological feasibility and that, until completion of development, have no

required substantial additional development by the Company. These projects were
to require substantial development and testing prior to reaching technological
feasibility. However, there could be no assurance that these projects would
reach technological feasibility or develop into products that would be sold
profitably by the Company. The intangible assets are being amortized over the
estimated useful life of three years. The Company recorded approximately $991,
$527 and $62 of amortization expense relating to these intangible assets during
1999, 1998 and 1997, respectively.

(5) INTANGIBLE ASSETS

    Intangible assets consist principally of goodwill and the value of acquired
technology. These intangibles were obtained from our acquisition of Folio,
ICentral and Mission Critical Technologies. The Company amortizes these

(6) LONG-TERM OBLIGATIONS

    (A) LINE-OF-CREDIT ARRANGEMENT

    The Company has an unsecured credit facility arrangement with a bank, which
provides up to $15,000 in financing in the form of a demand line of credit.
Borrowings under this line are limited to 80% of eligible domestic accounts
receivable and 90% of eligible foreign accounts receivable, as defined, and bear
interest at the prime lending rate (8.5% at December 31, 1999). The Company is
required to comply with certain restrictive covenants under this agreement and
the line is collateralized by the Company's accounts receivable. The Company was
in compliance with all such covenants at December 31, 1999. The outstanding
balance was $10,350 under this facility as of December 31, 1999. This line of
credit expires September 20, 2000 and is subject to annual renewal.

    (B) NOTES PAYABLE

    In April 1996, May 1997 and September 1998, the Company entered into
agreements with a bank to borrow up to $250, $250 and $400, respectively, for
equipment purchases. The agreements expired in April 1997, May 1997 and
June 1999, respectively, at which time all amounts outstanding were converted
into three-year term loans. Outstanding amounts bore interest at the prime rate
plus 1.5%, 1.5% and 1.25%, respectively. The total principal amounts outstanding
were $0 and $460 at December 31, 1999 and 1998, respectively. In connection with
these notes payable, the Company issued a warrant to purchase 1,317 shares of
common stock at $3.80 per share.

    In connection with the acquisition of Folio, (See Note 4(d)) the Company
issued an 8%, $10,000 promissory note payable to Reed Elsevier. The note was
payable in either cash or shares of common stock of the Company. During 1998,
the Company made a $5,000 payment on the note comprised of cash of $1,818 and
220,701 shares of common stock valued at $3,182. The balance of the note payable
was paid in cash in March 1999.

    (C) MORTGAGE

    In July 1998, the Company entered into a $2,800 mortgage of its Provo, Utah,
building which bears interest at the fixed rate of 8.5%. The mortgage principal
payments are based upon a 20-year term with a balloon payment of $2,468 due on
June 19, 2003.

    (D) OBLIGATIONS UNDER LICENSE AGREEMENT

    During 1994, the Company entered into a license agreement with a university
to utilize certain patented computer software. The Company expensed the present
value of the future commitments under contract, $217, as a component of research
and development expense during 1994. The balance of the obligation was $47 and
$90 at December 31, 1999 and 1998, respectively. The final installment is
scheduled to be repaid in 2000.

(7) INCOME TAXES

    The Company accounts for income taxes under SFAS No. 109, ACCOUNTING FOR
INCOME TAXES, the objective of which is to recognize the amount of current and
deferred income taxes payable or refundable at the date of the financial
statements as a result of all events that have been recognized in the
accompanying consolidated financial statements, as measured by enacted tax laws.

    The provision for income taxes for the years ended December 31, 1999, 1998
and 1997 consists of foreign income and withholding taxes.

    At December 31, 1999, the Company has net operating loss carryforwards for
federal income tax purposes of approximately $119,000, which expire through
2006 - 2019. The Company also has certain tax credits available to offset future
federal and state income taxes, if any. Net operating loss carryforwards and
credits are subject to review and possible adjustments by the Internal Revenue
Service and may be limited in the event of certain cumulative changes in excess
of 50% in the ownership interests of significant stockholders over a three-year
period. The Company believes it has experienced a change in ownership in excess
of 50%. The Company does not believe that this change in ownership will
significantly impact the Company's ability to utilize its net operating loss
carryforwards.

    The components of the Company's deferred tax asset are as follows:

(7) INCOME TAXES (CONTINUED)
    It is the Company's objective to become a profitable enterprise and to
realize the benefits of its deferred tax assets. However, in evaluating the
realizability of these deferred tax assets, management has considered the
Company's operating history, the volatility of the market in which it competes,
the operating losses incurred to date, and believes that given the significance
of this evidence, a full valuation reserve against its deferred tax assets is
required as of December 31, 1999 and 1998.

(8) REDEEMABLE CONVERTIBLE PREFERRED STOCK AND STOCKHOLDERS' EQUITY

    (A) PREFERRED STOCK

    In April 1996, the Company's Board of Directors authorized the issuance of
up to 2,000,000 shares of $.10 par value preferred stock. At December 31, 1999,
no shares are issued and outstanding.

    In connection with the merger with FutureTense, which was accounted for as a
pooling of interest, all outstanding shares of FutureTense preferred stock were
exchanged for the Company's common stock. The shares of Series A, B, C and D
Preferred Stock issued were as follows:

    (C) PRIVATE PLACEMENTS

    In June 1998, Intel Corporation made an investment in the Company,
purchasing 335,852 unregistered shares of the Company's common stock for an
aggregate purchase price of $5,000. The Company's content management product
line (IPS) currently supports the Intel environment and the Company will
continue to migrate appropriate commerce features from Transact to this
environment running on top of IPS. The Intel support will include the Itanium
(IA-64) processor.

    In July 1998, CMG Information Services, Inc., an investor and developer of
Internet companies ("CMG") and Capital Ventures International, a fund managed by
Heights Capital Management ("CVI"), made a $20,000 equity investment in the
Company. Pursuant to the terms of the agreements, the Company issued an
aggregate of 1,545,893 shares of common stock of the Company to CMG and CVI at a
price of $12.94 per share. In addition, the Company issued to CMG and CVI
warrants to purchase 334,728 shares of common stock at a price of $16.43 per
share which expire on July 30, 2003. The Company filed a registration statement
on Form S-3, covering all such shares of common stock, which was declared
effective by the Securities and Exchange Commission on August 13, 1998.

    (D) STOCKHOLDERS' RIGHTS

    In January 1998, the Company's Board of Directors adopted a Shareholder
Protection Rights Plan declaring a dividend of one right for each share of the
Company's common stock outstanding at the close of business on February 12,
1998. The rights entitle the Company's shareholders to purchase one
one-thousandth of a share of a series of junior participating preferred stock of
the Company at an exercise price of $65.00 per share. The rights become
exercisable in the event that another party acquires or announces its intention
to acquire beneficial ownership of 18% or more of the Company's common stock.
Such percentage may, at the Board's discretion, be lowered, although in no event
may it be lower than 10%. In the event of such an acquisition or similar event,
each right, except those owned by the acquirer, will enable the holder of the
right to purchase that number of common shares of the Company which equals the
exercise price of the right divided by one-half of the market price of the
common stock. In addition, if the Company is involved in a merger or other
transaction with another party in which it is not the surviving corporation, or
it sells or transfers 50% or more of its assets or earning power to another
party, each right will entitle its holder to purchase that number of shares of
common stock of the other party which equals the exercise price of the right
divided by one-half of the market price of such common stock. The rights expire
ten years from the date of the grant.

    (E) COMMON STOCK

    At December 31, 1999, the Company had outstanding 1,703,998 shares of common
stock which are subject to restriction agreements (the "Restriction Agreements")
under the 1996 Incentive Plan. Pursuant to the Restriction Agreements, the
Company has the right to repurchase any unvested shares of common stock in the
event of termination of employment with cause, as defined, or due to
stockholder's voluntary resignation with the Company at 25% of the then-current
fair market value of the common stock. Shares subject to the Restriction
Agreements vest quarterly over a five year period commencing December 1995,
subject to certain acceleration provisions. In connection with the consummation
of the merger of

(8) REDEEMABLE CONVERTIBLE PREFERRED STOCK AND STOCKHOLDERS' EQUITY (CONTINUED)
FutureTense the restrictions on these shares were accelerated and then converted
into shares of the Company's common stock.

    During 1996, FutureTense issued 1,057,786 shares of restricted common stock
to certain employees and consultants. The estimated value of these shares
totaled $110 and was recorded as deferred compensation and is being amortized as
compensation expense over the vesting period of the restricted common stock.

    In 1997, as a result of the resignation of one of the founding stockholders
of FutureTense who was a party to a Restriction Agreement, FutureTense
repurchased 268,800 shares of unvested common stock for $20. A compensation
charge of $19 was recorded for the difference between the original cost and the
repurchase price.

    In July 1998, 7,918 shares of unvested restricted stock, granted to a
consultant in 1996, were cancelled. The deferred compensation associated with
the grant was not significant at the date of cancellation.

    (F) STOCK OPTION PLANS

    During 1994, the Company's Board of Directors adopted the 1994 Stock
Incentive Plan (the 1994 Incentive Plan). Under the Incentive Plan, as amended,
the Company has reserved and may issue up to 19,201,000 shares of common stock
or options to purchase common stock. As of December 31, 1999, there were
2,158,000 shares available for issuance under the 1994 Incentive Plan.

    In September 1996, FutureTense's Board of Directors adopted the 1996
FutureTense Plan (the 1996 Incentive Plan) under which 1,125,000 shares of
common stock are reserved for issuance to employees, officers, directors and
consultants upon the exercise of options granted under the Plan. As of
December 31, 1999, there were 20,000 shares available for issuance under the
1996 Incentive Plan.

    In August 1999, the Company's Board of Directors adopted the the 1999 Stock
Incentive Plan (the 1999 Incentive Plan). Under the Incentive Plan, the Company
has reserved and may issue up to 4,000,000 shares of common stock or options to
purchase common stock. As of December 31, 1999, there were 4,000,000 shares
available for issuance under the 1999 Incentive Plan.

    Under the terms of the above mentioned Incentive Plans, the Board of
Directors may grant incentive stock options or non-qualified stock options to
purchase shares of the Company's common stock. The purchase price and vesting
schedule applicable to each option grant are determined by the Board of
Directors. Generally, options vest over a four-year period and expire 10 years
from the date of grant.

    In 1996, the Company's Board of Directors approved the 1996 Director Option
Plan (the Director Plan) whereby the Company has reserved and may issue up to
200,000 shares of common stock. Under the terms of the Director Plan, each newly
elected director will be granted an option to purchase 20,000 shares of common
stock. In addition, commencing with the 1998 annual meeting of the stockholders
and for every annual meeting of stockholders thereafter, each director who is
not a founder or employee of the Company will be granted an option to purchase
6,000 shares of common stock. Generally, these options vest over a four-year
period and expire 10 years from the date of grant. The vesting of these options
will accelerate upon a change of control, as defined. At December 31, 1999,
there were 84,400 options available for grant under this plan.

(8) REDEEMABLE CONVERTIBLE PREFERRED STOCK AND STOCKHOLDERS' EQUITY (CONTINUED)
    The Company recorded deferred compensation when stock options were granted
to employees at an exercise price per share that is less than the fair market
value on the date of the grant. Deferred compensation was recorded in an amount
equal to the excess of the fair market value per share over the exercise price
multiplied by the number of shares purchasable under the option. The Company
recorded $399, $41 and $138 of deferred compensation expense in 1999, 1998 and
1997, respectively, which represented the difference betweeen the fair market
value of the common stock on the date of grant, for accounting purposes, and the
exercise price.

    In November 1998, the Compensation Committee of the Board of Directors
authorized a Stock Option Exchange Program (the Program). Under the terms of the
program all current employees, excluding certain officers subject to
Regulation 16 had the option to request that the Company cancel their existing
options and replace them with a new option. Options for a total of 2,258,153
shares were surrendered under the program by employees and exchanged for new
options at the new option exercise price and vesting schedule. The new exercise
price was equal to the fair market value of the Company's common stock on
November 13, 1998, or $7.875. The repriced shares were subject to certain
selling restrictions though 1999. These repriced options are reflected as grants
and cancellations in the 1998 stock option activity below.

    The following is a summary of the stock option activity for all plans:

    The total value of the options granted to employees and stock issued under
the employee stock purchase plan during 1999, 1998 and 1997 was computed as
approximately $49,664, $32,320 and $16,962, respectively. Of these amounts
approximately $17,114, $7,870 and $8,924 would be charged to operations for the
years ended December 31, 1999, 1998 and 1997, respectively. The remaining
amount, approximately $36,594, would be amortized over the remaining vesting
periods. The pro forma effect of these option grants for the years ended
December 31, 1999, 1998 and 1997 is as follows:

    The resulting pro forma compensation expense may not be representative of
the amount to be expected in future years as the pro forma expense may vary
based upon the number of options granted. The Black-Scholes option pricing model
was developed for use in estimating the fair value of traded options that have
no vesting restrictions and are fully transferable. In addition, option pricing
models require the input of highly subjective assumptions, including expected
stock price volatility. Because the Company's employee stock options have
characteristics significantly different from those of traded options and because
changes in the subjective input assumptions can materially affect the fair value
estimate, in management's opinion, the existing models do not necessarily
provide a reliable single measure of the fair value of its employee stock
options.

    The Company has entered into agreements with certain stockholders that
provide for product and service revenues. The Company believes that the terms of
these transactions are on terms no less favorable to the Company than could be
obtained from unaffiliated third parties. The Company recognized product and
service revenues from related parties of approximately $259, $208 and $6,129,
during the years ended December 31, 1999, 1998 and 1997, respectively. The
Company had related party accounts receivable of approximately $71 and $5, and

respectively, from certain stockholders.

NextPage will pay the Company a minimum of $14,000 in guaranteed royalties,
during this period commencing July 1, 1999. The Company is recognizing these
royalties ratably over the three year period. At the end of the three-year
period NextPage has an option to obtain all rights, title and interests to the
Folio products for a purchase price equal to such products' estimated
fair-market value. In addition, the Company received $3,000 in software license
fees from NextPage in exchange for NextPage's non-exclusive, worldwide rights to
market and distribute the Company's commerce software products to the commercial
publishing industry. In connection with this distribution agreement, the Company
recorded $5,441 in commerce and other product revenues during 1999.

(12) EMPLOYEE BENEFIT PLAN

    In October 1995, the Company adopted a 401(k) savings and investment plan
(the 401(k) Plan) for eligible employees. Each participant may elect to
contribute up to 15% of his or her compensation for the plan year, subject to
certain limitations, as defined. Company matching contributions are made to the

To Open Market, Inc.:

    We have audited, in accordance with generally accepted auditing standards,
the financial statements of Open Market, Inc. and subsidiaries included in this
10-K and have issued our report thereon dated January 28, 2000. Our audits were
made for the purpose of forming an opinion on the basic consolidated financial

Company's management and is presented for purposes of complying with the
Securities and Exchange Commission's rules and is not part of the basic
financial statements. This schedule has been subjected to the auditing
procedures applied in the audits of the basic consolidated financial statements
and, in our opinion, fairly states, in all material respects, the financial data
required to be set forth therein in relation to the basic consolidated financial
statements taken as a whole.
