                               PROSPECTUS SUMMARY

    THIS SUMMARY IS QUALIFIED BY MORE DETAILED INFORMATION APPEARING IN OTHER
SECTIONS OF THE PROSPECTUS. THE OTHER INFORMATION IS IMPORTANT, SO PLEASE READ
THIS ENTIRE PROSPECTUS CAREFULLY.

                                  OUR BUSINESS

    We are a leading provider of business-to-business infrastructure software
products and services that enable organizations to easily and rapidly integrate
business applications within and across organizations over the Internet. Our
software allows organizations to link their business processes by sharing
services, conducting transactions and exchanging information in real-time, with
customers, suppliers and other trading partners. Our OpenBusiness solution
provides a robust, easy to configure integration platform that ensures reliable,
secure integration of complex, dynamic software applications and scales to
accommodate large numbers of business-to-business, or B2B, partners. We believe
our OpenBusiness solution allows our customers to integrate business processes
with their B2B partners with fewer alterations to their existing software
applications than current alternatives.

    Escalating competitive pressures, shifting supplier relationships and
diverse customer demands are forcing organizations of all sizes to quickly
embrace a new Internet-based B2B business model. This new model requires a
higher level of business process integration in which customers, suppliers and
other trading partners transact business electronically over the Internet. With
improved B2B integration, or B2Bi, organizations can more effectively pursue new
revenue opportunities and significantly improve operating efficiencies. We
believe many organizations will not be able to successfully compete in today's
global markets without embracing this new B2B business model.

    We have designed our solution to be rapidly deployed, permitting our
customers to reduce the time necessary to execute new Internet-based B2B
strategies. Through the use of eXtensible Markup Language, or XML, and support
for a broad range of additional communications standards, our solution provides
a high level of interoperability among disparate software applications. As a
result, our OpenBusiness solution, unlike other B2Bi solutions, allows
customers, suppliers and other trading partners to successfully integrate their
otherwise incompatible software applications without significant reprogramming
or adopting the same communications standards. In addition, to help our
customers adopt new B2B models and implement our OpenBusiness solution, we
provide a wide range of professional services, including strategic planning,
architectural design, project management and implementation services.

    Our OpenBusiness product line is comprised of our:

    - OPENBUSINESS INFRASTRUCTURE PLATFORM that provides the critical foundation
      for integrating an organization's disparate business applications,
      allowing them to be easily extended to their external B2B partners;

    - OPENBUSINESS GATEWAY, a recently released product that builds upon the
      functionality of the Infrastructure Platform by extending an
      organization's internally integrated applications to its B2B partners over
      the Internet; and

    - OPENBUSINESS PORTAL, a recently released product that can leverage the
      integration and access capabilities of the Infrastructure Platform and
      Gateway, allowing organizations to rapidly create a website to catalog
      business applications they choose to make available to their community of
      B2B partners.

    We market our products and services globally primarily through our direct
sales force, complemented by the selling and support efforts of value-added
resellers and system integrators. As of March 15, 2000, we had licensed our
OpenBusiness products or provided professional services to over 300 customers,
including Caterpillar, General Motors, Intel, Merrill Lynch, Nokia, Sprint and
Unisys.

                                  RISK FACTORS

    AN INVESTMENT IN OUR COMMON STOCK INVOLVES A HIGH DEGREE OF RISK. YOU SHOULD
CAREFULLY CONSIDER THE FOLLOWING RISK FACTORS AND THE OTHER INFORMATION IN THIS
PROSPECTUS, INCLUDING OUR CONSOLIDATED FINANCIAL STATEMENTS AND THE RELATED
NOTES, BEFORE INVESTING IN OUR COMMON STOCK. ANY OF THE FOLLOWING RISKS COULD
SERIOUSLY HARM OUR BUSINESS, OPERATING RESULTS OR FINANCIAL CONDITION AND CAUSE
THE TRADING PRICE OF OUR COMMON STOCK TO DECLINE. AS A RESULT, YOU COULD LOSE
ALL OR PART OF YOUR INVESTMENT.

                         RISKS RELATED TO OUR BUSINESS

WE EXPECT TO INCUR LOSSES IN THE FUTURE AND MAY NOT ACHIEVE OR MAINTAIN
PROFITABILITY.

    We have incurred net losses in each of the last three fiscal years as we
spent heavily, particularly during 1999, to develop our products and expand our
sales and marketing organization. Our net loss was $2.3 million in 1997,
$4.4 million in 1998 and $4.2 million in 1999. We expect to make significant
investments in our sales and marketing programs and research and development,
resulting in a substantial increase in our operating expense. Consequently, we
will need to generate significant additional revenue to achieve and maintain
profitability in the future. We may not be able to generate sufficient revenue
from sales of our products and related professional services to become
profitable. Even if we do achieve profitability, we may not sustain or increase
profitability on a quarterly or annual basis. We cannot predict when we will
operate profitably, if at all. If we fail to achieve or maintain profitability,
our stock price may decline.

OUR QUARTERLY FINANCIAL RESULTS ARE SUBJECT TO FLUCTUATIONS AND SEASONALITY
BECAUSE OF MANY FACTORS, WHICH COULD HARM OUR BUSINESS PROSPECTS AND LOWER OUR
STOCK PRICE.

    Our quarterly revenue and results of operations are difficult to predict. We
have experienced fluctuations in revenue and operating results from
quarter-to-quarter and anticipate that these fluctuations will continue. These
fluctuations are due to a variety of factors, some of which are outside of our
control, including:

    - our ability to attract new customers and retain existing customers;

    - the length and variability of our sales cycle, which makes it difficult to
      forecast the quarter in which our sales will occur;

    - the fact that a few customers typically provide a large portion of our
      revenue in any particular quarter;

    - the amount and timing of operating expense relating to the expansion of
      our business and operations;

    - our mix of license and service revenue;

    - the utilization rate for our professional services personnel and the need
      to staff customer projects with third party contractors;

    - changes in our pricing policies or our competitors' pricing policies;

    - the development of new products or product enhancements by us or our
      competitors;

    - our mix of domestic and international sales;

    - the market for B2Bi solutions and other general economic factors; and

    - changes to generally accepted accounting principles, especially those
      related to the recognition of software revenue.

                                       4

    In addition, we have also experienced and expect to continue to experience
seasonality in the sales of our OpenBusiness products. For example, we
anticipate that sales may be lower in our first fiscal quarter each year due to
patterns in the capital budgeting and purchasing cycles of our current and
prospective customers. These seasonal variations in our sales may lead to
fluctuations in our quarterly operating results.

    We also typically realize a significant portion of our license revenue in
the last few weeks of a quarter because of our customers' purchasing patterns.
As a result, we are subject to significant variations in license revenue and
results of operations if we incur a delay in a large customer's order. If we
fail to close one or more significant license agreements that we have targeted
to close in a given quarter, this failure could seriously harm our operating
results for that quarter. Failure to meet or exceed the expectation of
securities analysts or investors due to any of these or other factors may cause
our stock price to fall.

BECAUSE OUR B2BI PRODUCTS ARE RELATIVELY NEW, WE HAVE A LIMITED OPERATING
HISTORY WITH WHICH YOU CAN EVALUATE OUR CURRENT BUSINESS MODEL AND PROSPECTS.

    We shipped the first commercial version of our OpenBusiness Integration
Platform in October 1997 and released our OpenBusiness Gateway and Portal
products to customers in late March 2000. We have sold only one license of our
OpenBusiness Gateway product and no licenses of our OpenBusiness Portal product,
and, to date, our Gateway customer has not completely implemented this product.
We have engaged in very limited marketing of our Gateway and Portal products.
Accordingly, we have only a limited operating history with which you can
evaluate our current business model and our prospects.

    We expect licenses of, and professional services related to, our
OpenBusiness products to account for substantially all of our total revenue for
the foreseeable future. We also expect revenue from licenses of our OpenBusiness
products to constitute an increasing portion of our total revenue. We intend to
continue to enhance our OpenBusiness products with the release of future
versions, upgrades and increased functionality.

    Because our OpenBusiness products are at an early stage of
commercialization, it is difficult for us to forecast the level of market
acceptance that our OpenBusiness solution will attain. Some of the risks we face
include:

    - internal information technology departments of potential customers may
      choose to create their own B2Bi solutions internally or through
      third-party, custom developers;

    - competitors may develop products, technologies or capabilities that render
      our OpenBusiness products and related professional services obsolete or
      noncompetitive or that shorten the life cycles of these products;

    - the market may not accept our OpenBusiness products;

    - we may not be able to attract and retain a broad customer base; and

    - we may not be able to negotiate and maintain favorable strategic
      relationships.

    Failure to successfully manage these risks could harm our business and cause
our stock price to fall.

    Furthermore, to remain competitive, products like ours typically require
frequent updates that add new features. We may not succeed in creating and
licensing updated or new versions of our OpenBusiness products. A decline in
demand for, or in the average licensing price of, our OpenBusiness products
would have a direct negative effect on our business and our ability to increase
our mix of license revenue relative to service revenue and could cause our stock
price to fall.

                                       5

IF BROAD MARKET ACCEPTANCE FOR XML DOES NOT DEVELOP, SALES OF OUR OPENBUSINESS
PRODUCTS MAY SUFFER.

    We have designed our OpenBusiness products to use eXtensible Markup
Language, or XML, an emerging standard for sharing data over the Internet.
Although we believe that XML will achieve broad market acceptance in the near
future, it is possible that the market will perceive a competing standard as
superior to XML. If a competing standard replaced XML, the market might not
accept XML-based products. In addition, our OpenBusiness products might not be
compatible with the new standard or we might not be able to develop a product
using this standard in a timely manner. Consequently, a failure of XML-based
products to achieve broad market acceptance or the introduction of a competing
standard that the market perceives as superior could adversely affect our sales
of our OpenBusiness products and could cause our stock price to decline.

IF WE CANNOT ATTRACT AND RETAIN THE TECHNICAL PERSONNEL NECESSARY TO CONTINUE
OUR RESEARCH AND DEVELOPMENT EFFORTS, OUR BUSINESS WILL SUFFER.

    We cannot be certain that we can hire or retain a sufficient number of
highly qualified technical personnel. Our business depends on the continued
development and evolution of our OpenBusiness products. Competition for
qualified technical personnel is intense, particularly because we are in a new
area of software development and only a limited number of individuals have
acquired the skills they need to develop and maintain the products we offer. Our
competitors have attempted to hire our employees away from us, and we expect
that they will continue these attempts in the future. Failure to attract and
retain a sufficient number of qualified technical personnel will harm our
business and could cause our stock price to fall.

THE LOSS OF A MAJOR CUSTOMER COULD HARM OUR OPERATING RESULTS AND OUR BUSINESS.

    We generally derive a significant portion of our revenue from a small number
of relatively large sales, and our business generally depends on a limited
number of customers. For example, in 1999, two customers accounted for an
aggregate of approximately 46% of our total revenue, ClubCorp for approximately
26% and General Motors for approximately 20%. In addition, our top ten customers
in each of the last three fiscal years accounted for more than 70% of our total
revenue in each of those fiscal years. We may continue to derive a significant
portion of our revenue from a relatively small number of customers in the
future. A major customer's decision not to use our products or our professional
services could harm our business, operating results and financial condition and
cause our stock price to fall.

THE MARKET FOR B2BI SOLUTIONS IS HIGHLY COMPETITIVE, AND WE MAY NOT BE ABLE TO
COMPETE EFFECTIVELY.

    The market for B2Bi solutions is rapidly changing and intensely competitive.
We expect competition to intensify as the number of entrants increases and as
other software companies expand into this marketplace. Our current and potential
competitors include other B2Bi vendors, internal information technology
departments, enterprise application integration software vendors and other large
software vendors. Many of our existing and potential competitors have better
brand recognition, longer operating histories, larger customer bases and greater
financial, technical, marketing and other resources than us. As a result, they
may be able to leverage these advantages to gain market share from us. In
addition, they may be able to respond more effectively than we can to changing
technologies, conditions or customer demands, especially during economic
downturns. Increased competition could significantly reduce our future revenue
and increase our operating losses due to price reductions, lower gross margins
or lost market share, which could harm our business and cause our stock price to
decline.

                                       6

WE INTEND TO EXPAND OUR INTERNATIONAL SALES EFFORTS, AND FAILURE TO GROW OUR
INTERNATIONAL OPERATIONS SUCCESSFULLY COULD HARM OUR BUSINESS AND CAUSE OUR
STOCK PRICE TO DECLINE.

    We intend to expand our international sales efforts, particularly in Europe
and Asia, but we have very limited experience in selling, marketing, licensing
and supporting our products and professional services abroad. Expansion of our
international operations will require a significant amount of attention from our
management and substantial financial resources. In addition, doing business
internationally involves additional risks, particularly:

    - unexpected changes in regulatory requirements, taxes, trade laws and
      tariffs;

    - restrictions on repatriation of earnings;

    - fluctuations in currency exchange rates;

    - less protective intellectual property rights;

    - differing labor regulations;

    - changes in a country's or region's political or economic conditions; and

    - greater difficulty in staffing and managing foreign operations.

    Because of these risks, we may not achieve an acceptable return on our
investment or be able to compete effectively in international markets. Failure
to grow our international operations successfully and in a timely manner could
harm our business and cause our stock price to fall.

A FAILURE TO EXPAND OUR SALES FORCE AND DISTRIBUTION CHANNELS WILL ADVERSELY
AFFECT OUR BUSINESS.

    To increase market awareness and sales of our OpenBusiness products and
related professional services, we plan to expand our direct and indirect sales
and distribution efforts, both domestically and internationally. Distribution of
our software and professional services offerings requires a sophisticated sales
effort targeted at multiple departments within an organization. Competition for
qualified sales and marketing personnel is intense, and we may not be able to
attract and retain adequate numbers of these personnel to maintain our growth.
Even if we can attract qualified personnel, these personnel require training and
will take time to achieve full productivity. Our competitors have attempted to
hire our employees away from us, and we expect that they will continue these
attempts in the future. Failure to attract and retain qualified sales and
marketing personnel could harm sales of our products and professional services
and cause our stock price to decline.

    In addition to expanding our sales force, we also plan to expand our
relationships with system integrators and other technology leaders to further
develop our indirect sales channel. However, we may be unable to expand these
relationships or develop new relationships in a timely manner. As we continue to
develop our indirect sales channel, we will need to manage potential conflicts
between our direct sales force and third party reselling efforts. Failure to
expand and develop these relationships or successfully manage these conflicts
could harm our business and cause our stock price to decline.

IF WE CANNOT MEET OUR FUTURE CAPITAL REQUIREMENTS, OUR BUSINESS WILL SUFFER.

    We believe that the net proceeds from this offering, together with our
existing working capital immediately prior to this offering, will be sufficient
to meet our anticipated working capital and capital expenditure requirements
through at least the next twelve months. The time period for which we believe
our capital is sufficient is an estimate. The actual time period may differ
materially as a result of a number of factors, risks and uncertainties. We may
need to raise additional funds in the future through public or private debt or
equity financings in order to:

                                       7

    - fund operating losses;

    - take advantage of opportunities, including more rapid expansion or
      acquisitions of complementary businesses or technologies;

    - hire, train and retain employees;

    - develop new products or professional services; or

    - respond to economic and competitive pressures.

    Future additional financing may not be available on terms favorable to us,
if at all. If adequate funds are not available or are not available on
acceptable terms, our operating results and financial condition may suffer, and
our stock price may decline.

OUR BUSINESS WILL SUFFER IF WE DO NOT EXPAND OUR PROFESSIONAL SERVICES
ORGANIZATION.

    We cannot be certain that we can attract or retain a sufficient number of
highly qualified professional services personnel. Customers that license our
software may engage our professional services staff to assist with support,
training, consulting and implementation. We believe that growth in our product
licenses depends on our ability to provide our customers with these services. As
a result, we plan to increase the number of our professional services personnel
to meet these needs. Competition for qualified personnel is intense,
particularly because we are in a new market and only a limited number of
individuals have acquired the skills they need to provide the services our
customers require. New professional services personnel will require training and
education and take time to reach full productivity. We also intend to use more
costly third party consultants to supplement our own professional services
staff. Our business may suffer and our stock price may fall, if we are unable to
expand our professional services organization.

FAILURE TO MANAGE OUR PLANNED GROWTH COULD HARM OUR BUSINESS.

    Our ability to successfully license products, sell professional services and
implement our business plan in a rapidly evolving market requires an effective
plan for managing our future growth. We plan to increase the scope of our
operations at a rapid rate. Future expansion efforts will be expensive and may
strain our managerial and other resources. To manage future growth effectively,
we must maintain and enhance our financial and accounting systems and controls,
integrate new personnel and manage expanded operations. If we do not manage
growth properly, it could harm our operating results and financial condition and
cause our stock price to fall.

IF WE CANNOT DEVELOP ENHANCEMENTS TO, AND NEW VERSIONS OF, OUR OPENBUSINESS
PRODUCTS IN A TIMELY AND EFFECTIVE MANNER, OUR OPERATING RESULTS COULD SUFFER.

    We have recently released the first version of our OpenBusiness Gateway and
OpenBusiness Portal and plan to release enhancements to, and new versions of,
this line of products. Because of the complexity of our OpenBusiness products,
our internal testing and customer testing may reveal desirable feature
enhancements that could lead us to postpone the release of new versions. In
addition, the reallocation of resources associated with any postponement could
cause delays in the development and release of future enhancements to, and new
versions of, our currently available OpenBusiness products. We may not be able
to successfully complete the development of currently planned or future
enhancements or new versions in a timely and efficient manner. Any failed or
delayed development efforts could harm our operating results and lower our stock
price.

IF OUR OPENBUSINESS PRODUCTS CONTAIN DEFECTS, WE COULD LOSE CUSTOMERS AND
REVENUE.

    Products as complex as ours often contain known errors, undetected errors
and performance problems. Software developers frequently find many serious
defects during the period immediately following introduction of new software or
enhancements to existing software. These defects may be present in the recent
release of our OpenBusiness products or our planned releases of enhancements to
our OpenBusiness products. Although we attempt to resolve all errors that we
believe our customers

                                       8

would consider to be serious, our software is not error-free. Our customers may
consider as serious those known errors that we consider to be minor. We or our
customers may discover undetected errors and performance problems in the future.
Defects in our software could lead to the following:

    - delays in customer acceptance of our product;

    - loss of existing customers;

    - harm to our reputation; and

    - liability to our customers or third parties.

    Accordingly, any defects could result in lost revenue and could harm our
business and lower our stock price.

OUR EXECUTIVE OFFICERS ARE CRITICAL TO OUR BUSINESS, BUT MAY NOT REMAIN WITH US
IN THE FUTURE.

    Our future success depends upon the continued service of our executive
officers, and none of our executive officers are bound by an employment
agreement for any specific term. The loss of services of one or more of our
executive officers, or their decision to join a competitor or otherwise compete
directly or indirectly with us, could harm our business and lower our stock
price. In particular, David Norris, our Chairman of the Board, Chief Executive
Officer and President, would be especially difficult to replace and his
departure could harm our business and lower our stock price.

IF WE ARE UNABLE TO PROTECT OUR INTELLECTUAL PROPERTY, OUR BUSINESS AND
COMPETITIVE POSITION MAY SUFFER.

    Our success depends heavily upon our proprietary technology and other
intellectual property rights. To date, we have relied primarily on a combination
of employment agreements, contractual provisions and copyright, trade secret,
trademark and patent laws to protect our proprietary technology. We have 17
pending patent applications for technology related to our OpenBusiness products,
but we cannot assure you that these applications will be successfully issued. In
addition, others may infringe on our patent or other intellectual property
rights. A few of our agreements would allow others to obtain the source code for
our products in the event of bankruptcy and similar circumstances, which may
limit our ability to protect our intellectual property rights in the future.
Litigation to enforce our intellectual property rights or protect our trade
secrets could result in substantial costs and may not be successful. In
addition, the laws of some foreign countries may not protect our intellectual
property rights to the same extent as do the laws of the United States. Our
means of protecting our intellectual property rights in the United States or
abroad may not be adequate to fully protect our intellectual property rights.
Any inability to protect our intellectual property rights could seriously harm
our business, stock price and ability to compete in the B2Bi solutions market.

OTHERS MAY CLAIM THAT WE INFRINGE UPON THEIR INTELLECTUAL PROPERTY RIGHTS.

    Litigation regarding intellectual property rights is common in the software
industry. We expect that B2Bi products and services may be increasingly subject
to infringement claims as the number of competitors in our industry segment
grows and the functionality of products in different industry segments overlaps.
Although we believe that our intellectual property rights are sufficient to
allow us to market our OpenBusiness products without incurring liability, others
may still bring claims of infringement against us. These claims may be with or
without merit. Any litigation to defend against claims of infringement or
invalidity could result in substantial costs and diversion of resources.
Furthermore, a party making such a claim could secure a judgment that requires
us to pay substantial damages or that prevents us from licensing our products.
Any of these events could harm our business, and lower our stock price.

    In addition, we have agreed, and may agree in the future, to indemnify some
of our customers against claims that our software infringes upon the
intellectual property rights of others. We could incur substantial costs in
defending ourselves and our customers against infringement claims. In the event
of

                                       9

a claim of infringement, we and our customers may need to obtain one or more
licenses from others. We, or our customers, may be unable to obtain necessary
licenses from others at a reasonable cost, or at all. Defense of any lawsuit or
failure to obtain any required licenses could harm our business and result in
decline in our stock price.

ACQUISITIONS OF COMPANIES OR TECHNOLOGIES OR JOINT VENTURE INVESTMENTS MAY
DISRUPT OUR BUSINESS OR DILUTE STOCKHOLDER VALUE.

    We may acquire companies, products or technologies or enter into joint
ventures. If we are unable to integrate these acquisitions with our existing
operations, we may not receive the intended benefits of the acquisitions. In
addition, acquisitions may subject us to unanticipated liabilities or risks. Any
acquisition or joint venture may temporarily disrupt our operations and divert
management's attention from day-to-day operations.

    If we make future acquisitions, we may incur debt or issue equity securities
in order to finance the acquisitions. The issuance of equity securities for any
acquisition could cause our stockholders to suffer significant dilution. In
addition, our profitability may suffer due to acquisition-related expenses,
additional interest expense or amortization costs for acquired goodwill and
other intangible assets and operating losses generated by the acquired entity or
joint venture. Acquisitions and joint ventures that do not successfully
complement our existing operations may harm our business and cause our stock
price to decrease.

IF OUR STRATEGIC RELATIONSHIPS TERMINATE, OUR BUSINESS COULD SUFFER.

    We rely upon strategic relationships with system integrators and other
technology leaders. These relationships expose our products to many potential
customers to which we may not otherwise have access. In addition, these
relationships provide us with insights into new technology and with third-party
service providers that our customers can use for implementation assistance.
Maintaining and expanding these relationships is a part of our business
strategy. However, some of our current and potential strategic partners are
actual or potential competitors, which may impair the viability of these
relationships. Termination of, or failure to expand, any of these relationships
with these organizations could cause us to lose important opportunities,
including sales and marketing opportunities, and our business may suffer and our
stock price may decline.

WE MUST MEET THE CHANGING NEEDS OF OUR CUSTOMERS IN THE MARKET FOR B2BI
SOLUTIONS IN ORDER TO SUCCEED.

    The characteristics of the market for B2Bi solutions include rapidly
changing technology, evolving industry standards and frequent new product
announcements. In order to succeed, we must adapt to market changes by
continually improving the performance, features and reliability of our
OpenBusiness products. We could incur substantial costs to modify our products
and professional services in order to adapt to these changes. Our incurring
significant costs without adequate results or inability to adapt rapidly to
these changes could harm our business and cause our stock price to fall.

    In addition, our customers and their B2B partners use a wide variety of
constantly changing hardware, applications and server platforms. If our products
are unable to support a variety of these or are unable to adapt to the rapidly
changing B2Bi market, our products may fail to gain and maintain broad market
acceptance, causing our operating results and stock price to decline.

IF THE MARKET FOR INTERNET-BASED B2BI SOLUTIONS DOES NOT EXPAND, OUR BUSINESS
WILL SUFFER.

    The Internet-based B2Bi solutions market is relatively new and may not grow
as fast as we expect. Our potential customers are just beginning to seek
solutions for managing interactions with their trading partners, and concerns
about the security, reliability and quality of the services delivered over the
Internet may inhibit the growth of our market. If Internet-based B2Bi solutions
fail to achieve market acceptance, our business may suffer and our stock price
may fall.

                         RISKS RELATED TO OUR INDUSTRY

CONTINUED GROWTH OF THE INTERNET AS A METHOD OF CONDUCTING BUSINESS IS NECESSARY
FOR OUR SUCCESSFUL GROWTH.

    Our future success depends upon the widespread acceptance and use of the
Internet as an effective medium for B2B commerce. The failure of the Internet to
continue to develop as a commercial or business medium could harm our business
and stock price. A number of factors could limit the acceptance and use of the
Internet for B2B commerce. These factors include the growth and use of the
Internet in general, the relative ease of conducting business on the Internet
and the efficiencies and improvements that conducting commerce on the Internet
provides.

THE SUCCESS OF OUR BUSINESS DEPENDS UPON THE SPEED AND RELIABILITY OF THE
INTERNET AND OUR CUSTOMERS' INTERNAL NETWORKS.

    The recent growth in Internet traffic has caused frequent periods of
decreased operating performance of systems and applications accessed over the
Internet. If Internet usage continues to grow rapidly, the underlying
infrastructure may not be able to support these demands, and performance and
reliability may decline. If outages or delays on the Internet occur frequently
or increase in frequency, B2B commerce could grow more slowly or decline, which
may reduce the demand for our OpenBusiness solution. The speed and reliability
of both the Internet and our customers' internal networks limit the ability of
our products to satisfy our customers' needs. Consequently, improvements made to
the entire Internet, as well as to our individual customers' networking
infrastructures, to alleviate overloading and congestion will accelerate the
emergence and growth of the market for our software. Failure to make these
improvements will hinder the ability of our customers to utilize our solution,
and our business may suffer, and our stock price may decline.

INTERNET COMMERCE INVOLVES INCREASED SECURITY RISKS AND MAY DETER FUTURE USE OF
OUR PRODUCTS AND SERVICES.

    Internet-based B2B commerce depends upon the secure transmission of
confidential information over public networks. Advances in computer
capabilities, new discoveries in the field of cryptography or other developments
may result in a compromise or breach of the security features contained in our
software or the algorithms that our customers and their B2B partners use to
protect content and transactions over the Internet or proprietary information in
our customers' and their partners' databases. Anyone who is able to circumvent
security measures could misappropriate proprietary, confidential customer
information or cause interruptions in our customers' and their partners'
operations. Our customers and their business partners may need to incur
significant costs to protect against security breaches or to alleviate problems
caused by breaches, reducing their demand for our products and services.
Further, a well-publicized compromise of security could deter businesses from
using the Internet to conduct transactions that involve transmitting
confidential information. The failure of the security features of our products
to prevent security breaches, or well publicized security breaches affecting the
Internet in general, could significantly harm our business and our stock price.

CHANGES IN THE LAWS RELATING TO THE INTERNET COULD ADVERSELY AFFECT OUR
  BUSINESS.

    Regulation of the Internet is largely unsettled. The adoption of laws or
regulations that increase the costs or administrative burdens of doing business
using the Internet could cause companies to seek an alternative means of
transacting business. If the adoption of new Internet laws or regulations causes
companies to seek alternative methods for conducting business, the demand for
our products and services could decrease, harming our business and our stock
price.

                         RISKS RELATED TO THIS OFFERING

BECAUSE A FEW EXISTING STOCKHOLDERS OWN A LARGE PERCENTAGE OF OUR VOTING STOCK,
OTHER STOCKHOLDERS WILL HAVE LIMITED VOTING POWER.

    Following consummation of this offering, our officers, directors and their
affiliates will beneficially own or control approximately   % of our common
stock. In combination with our 5% stockholders, this group controls   % of the
outstanding shares of our stock. As a result, if these persons act together,
they will have the ability to control all matters submitted to our stockholders
for approval, including the election and removal of directors and the approval
of any merger, consolidation or sale of all or substantially all of our assets.
These stockholders may make decisions that are adverse to your interests.

SUBSTANTIAL FUTURE SALES OF OUR COMMON STOCK MAY DEPRESS OUR STOCK PRICE.

    Sales of a significant number of shares of our common stock after this
offering could cause the market price of our common stock to decline or could
adversely affect our ability to raise money through the sale of additional
equity securities. Our directors, executive officers and 5% stockholders
collectively will beneficially own 26,188,731 shares of common stock following
this offering, not including shares they have the right to acquire through the
exercise of options. Each of these persons and entities has entered into a
lock-up agreement, prohibiting them from selling or otherwise disposing of any
shares for 180 days after the date of this prospectus without the approval of
Donaldson, Lufkin & Jenrette. However, holders who have not been officers,
directors or affiliates of our company on or since the date of this prospectus
may be eligible to sell their shares 90 days after the date of this prospectus.
In addition, Donaldson, Lufkin & Jenrette has approved pledges of up to
3,609,446 shares of common stock to secure loans. If a default occurs under a
loan, the lender may foreclose upon and sell any pledged shares. When the

officers and 5% stockholders will become eligible for sale, subject to
limitations provided by applicable law.

WE HAVE BROAD DISCRETION TO USE THE OFFERING PROCEEDS, AND THE INVESTMENT OF
THESE PROCEEDS MAY NOT YIELD RETURNS THAT YOU WILL CONSIDER SUFFICIENT.

    We have not allocated most of the net proceeds of this offering for specific
purposes. Thus, our management has broad discretion over how we use these
proceeds and could spend most of these proceeds in ways with which our
stockholders may not agree. Our management may invest the proceeds in ways that
do not yield returns that you will consider sufficient.

THERE MAY NOT BE AN ACTIVE TRADING MARKET FOR OUR STOCK AFTER THE OFFERING,
CAUSING YOU TO LOSE ALL OR PART OF YOUR INVESTMENT.

    Prior to this offering, there has not been a public market for our common
stock. An active public market for our common stock may not develop or continue
after this offering. We have negotiated with representatives of the underwriters
to determine the initial public offering price. The trading prices of many
technology companies' stocks are at or near historical highs and reflect
financial ratios substantially above historic levels. We cannot be certain that
these trading prices or ratios will continue. As a result, the trading market
price of our common stock may decline below our initial public offering price.

THE PRICE VOLATILITY OF INTERNET-RELATED STOCKS MAY CAUSE OUR STOCK PRICE TO
  DECLINE.

    The stock market, and specifically the stock prices of Internet-related
companies, has been very volatile. This volatility is often not related to the
operating performance of the companies. This broad market volatility and
industry volatility may substantially reduce the price of our common stock,
without

                                       12

regard to our operating performance. Fluctuations in the price of our common
stock may affect our visibility and credibility in the market for B2Bi
solutions. If broad fluctuations occur in the market price of our common stock,
you may be unable to resell your shares if at or above the offering price.

    Plaintiffs have often brought securities class action litigation against
companies that experience volatility in the market price of their securities.
Litigation brought against us could result in substantial costs to us in
defending against a lawsuit and could divert management's attention from our
business.

AS A NEW INVESTOR, YOU WILL EXPERIENCE IMMEDIATE AND SUBSTANTIAL DILUTION IN THE
BOOK VALUE OF YOUR INVESTMENT.

    If you purchase shares of our common stock in this offering, you will incur
immediate and substantial dilution in pro forma net tangible book value. This
dilution is due in large part to the fact that our earlier investors paid
substantially less than the public offering price when they purchased their
shares. If the holders of outstanding options and warrants exercise those
options and warrants, you will incur further dilution.

A CUSTOMER CONTRACT, OUR CORPORATE GOVERNANCE DOCUMENTS AND DELAWARE LAW CONTAIN
CERTAIN ANTI-TAKEOVER PROVISIONS.

    We have granted one of our licensees a right of first refusal to acquire a
significant portion of our OpenBusiness Infrastructure Platform if we sell our
company or those portions containing the licensed technology. This right of
first refusal, along with provisions of our certificate of incorporation, our
bylaws and Delaware law, could make it more difficult to acquire us, even if
doing so would be beneficial to our stockholders.

                                       13

               SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

    Some of the statements under "Summary," "Risk Factors," "Management's
Discussion and Analysis of Financial Condition and Results of Operations,"
"Business" and elsewhere in this prospectus constitute forward-looking
statements. These statements relate to future events or other future financial
performance, and are identified by terminology such as "may," "will," "should,"
"expects," "scheduled," "plans," "intends," "anticipates," "believes,"
"estimates," "aims," "potential" or "continue" or the negative of such terms and
other comparable terminology. These statements are only predictions. In
evaluating these statements, you should specifically consider various factors,
including the risks outlined under "Risk Factors." These factors may cause our
actual results to differ materially from any forward-looking statement.

    This prospectus contains market data related to our business, the Internet
and e-commerce. This market data includes projections that are based on a number
of assumptions. If these assumptions turn out to be incorrect, actual results
may differ from the projections based on these assumptions. As a result, our
markets may not grow at the rates projected by these data, or at all. The
failure of these markets to grow at these projected rates may have a material
adverse effect on our business, results of operations, financial condition and
stock price.

    Although we believe that the expectations reflected in the forward-looking
statements are reasonable, we cannot assure you that our future results, levels
of activity, performance or goals will be achieved. We undertake no obligation
to update any of the forward-looking statements after the date of this
prospectus to conform these statements to reflect the occurrence of
unanticipated events.

                                USE OF PROCEEDS

    We estimate that the net proceeds to us from the sale of the       shares of
common stock we are selling in this offering will be approximately $    million,
at an assumed initial public offering price of $    per share, after deducting
estimated offering expenses of approximately $        million and underwriters'
discounts and commissions payable by us. If the underwriters exercise their
over-allotment option in full, we estimate that the net proceeds to us will be
approximately $        million.

    We intend to use the net proceeds we receive from this offering primarily
for working capital and other general corporate purposes, including funding
operating losses. We also intend to use approximately $3.0 million of the net
proceeds of this offering to repay outstanding indebtedness. Of this amount,
approximately $2.2 million bears interest at an effective rate of approximately
15.2% and matures in June 2001 and approximately $800,000 bears interest at a
variable interest rate that at March 15, 2000 was approximately 9.8% and matures
in April 2000. Other than the repayment of this indebtedness, we have not
identified specific uses for the net proceeds of this offering, and management
will have broad discretion over their use and investment. Pending their use, we
plan to invest the net proceeds in interest-bearing, investment grade
securities. We may use a portion of the net proceeds to acquire or invest in
technology or businesses that are complementary to our business, although we
have no current plans in this regard.

                                DIVIDEND POLICY

    We have never paid any cash dividends on our common stock and do not intend
to pay any cash dividends on our common stock in the foreseeable future. We
currently intend to retain any earnings for use in the operation of our
business. Payment of any future dividends will be at the discretion of our board
of directors after taking into account various factors, including our financial
condition, operating results, current and anticipated cash needs and plans for
expansion. In addition, the terms of our revolving line of credit prohibit us
from paying dividends without the lender's consent.

                                 CAPITALIZATION

    The following table sets forth our cash position, current portion of
long-term obligations and total capitalization as of December 31, 1999.

    The pro forma column of the table gives effect to:

    - increases in our authorized common stock from 20,000,000 shares to
      95,000,000 shares subsequent to December 31, 1999;

    - the automatic conversion of all outstanding shares of our preferred stock
      into shares of common stock upon the closing of this offering; and

    - the automatic elimination of redemption rights on 1,195,236 shares of our
      common stock upon the closing of this offering.

    The pro forma as adjusted column of the table gives effect to the sale in
this offering of       shares of common stock at an assumed price of $       per
share, less estimated underwriting discounts and estimated offering expenses
payable by us, and the application of the net proceeds from this offering as
described in "Use of Proceeds."

    This table should be read together with "Management's Discussion and
Analysis of Financial Condition and Results of Operations" and the financial
statements and related notes appearing elsewhere in this prospectus.

                                    DILUTION

    Our pro forma net tangible book value as of December 31, 1999, after giving
effect to the conversion of all outstanding shares of preferred stock into
9,167,567 shares of common stock at a ratio of 2.8 shares of common stock for
each share of preferred stock outstanding, upon the closing of this offering,
was approximately $6.0 million, or approximately $0.20 per share. Pro forma net
tangible book value per share represents the amount of our total tangible assets
less total liabilities, divided by 30,047,835 shares of common stock outstanding
after giving effect to the conversion of all outstanding shares of preferred
stock into shares of common stock and elimination of the redemption rights on
1,195,236 shares of common stock upon completion of this offering.

    Dilution per share to new investors represents the difference between the
amount per share paid by purchasers of our common stock in this offering and the
pro forma net tangible book value per share of common stock immediately after
completion of this offering. After giving effect to the sale by us of   shares
of common stock in this offering at an assumed initial offering price of $
per share, and after deducting the estimated underwriting discounts and
commissions and estimated offering expenses payable by us, our pro forma net
tangible book value as of December 31, 1999, would have been $      , or $
per share. This represents an immediate increase in net tangible book value of
$      per share to existing stockholders and an immediate dilution in net
tangible book value of $      per share to purchasers of common stock in this
offering, as illustrated in the following table:

                            SELECTED FINANCIAL DATA

    The following selected financial data should be read in conjunction with our
financial statements and the notes to the financial statements and "Management's
Discussion and Analysis of Financial Condition and Results of Operations," which
are included elsewhere in this prospectus. We derived the statement of
operations data for the years ended December 31, 1997, 1998 and 1999 and the
balance sheet data as of December 31, 1998 and 1999 from our financial
statements, which have been audited by Ernst & Young LLP, independent auditors,

from the years ended December 31, 1995 and 1996 and the balance sheet data as of
December 31, 1995, 1996 and 1997 are derived from our financial statements for
the years then ended. Historical results are not necessarily indicative of
future results. The pro forma information in the table below gives effect to the
automatic conversion of all outstanding shares of preferred stock into shares of
common stock, as if the shares had converted immediately upon issuance, and
elimination of common stock redemption rights.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS

    THE FOLLOWING DISCUSSION AND ANALYSIS OF THE FINANCIAL CONDITION AND RESULTS
OF OPERATIONS OF OBJECTSPACE SHOULD BE READ IN CONJUNCTION WITH "SELECTED
FINANCIAL DATA" AND OUR FINANCIAL STATEMENTS AND RELATED NOTES APPEARING
ELSEWHERE IN THIS PROSPECTUS. THIS DISCUSSION AND ANALYSIS CONTAINS FORWARD-
LOOKING STATEMENTS THAT INVOLVE RISKS, UNCERTAINTIES AND ASSUMPTIONS. OUR ACTUAL
RESULTS MAY DIFFER MATERIALLY FROM THOSE ANTICIPATED IN THESE FORWARD-LOOKING
STATEMENTS AS A RESULT OF CERTAIN FACTORS, INCLUDING, BUT NOT LIMITED TO, THOSE
SET FORTH UNDER "RISK FACTORS" AND ELSEWHERE IN THIS PROSPECTUS.

OVERVIEW

    We are a leading provider of business-to-business infrastructure software
products and services that enable organizations to easily and rapidly integrate
business applications within and across organizations over the Internet.

    At our inception in August 1992, we focused on providing services to assist
organizations in developing business software applications. In March 1994, we
introduced our first software product, which supported C++ applications
development. During October 1997, with the first license of our OpenBusiness
Infrastructure Platform, we shifted our focus from the C++ product line towards
B2Bi products. In each of September 1999 and March 2000, we sold businesses that
did not align with our strategic focus on B2Bi products. Both of these
businesses are treated in our financial statements as discontinued operations.

    Our revenue is derived from sales of licenses of our products to end user
companies and original equipment manufacturers, or OEMs, and related services.
Historically, service revenue has constituted the substantial majority of our
revenue. However, as a result of the increasing acceptance of our OpenBusiness
products, license revenue has comprised an increasingly larger percentage of
total revenue. Specifically, license revenue accounted for approximately 26.1%
of our revenue in 1999 compared to approximately 7.7% of our revenue in 1998. We
expect license revenue to continue to increase as a percentage of total revenue.
We market our products and services globally through our direct sales force,
resellers and system integrators. We also believe our participation in a number
of technology and standards organizations, and the conformity of our products to
those standards, has increased the penetration and market acceptance of our B2Bi
solutions.

    License revenue on product licenses to end user companies is recognized upon
shipment of our products, provided that the fee is fixed and determinable,
persuasive evidence of an arrangement exists, collection of the resulting
receivable is considered probable and vendor-specific objective evidence exists
to allow allocation of the total fee to elements of the arrangement. License
revenue from resale of our products by OEMs is recognized at the time the OEM
delivers our product to their customer. Historically, we have not experienced
significant returns or exchanges of our products.

    Service revenue includes professional services, maintenance, support and
reimbursable expenses. Service revenue is billed on either a time-and-materials
or fixed-fee basis. We generally charge for our professional services on a
time-and-materials basis. Service revenue realized from time-and-materials
professional services contracts is recognized as the service is provided.
Service revenue realized from fixed-fee professional services contracts is
recognized using the percentage of completion method based on hours incurred
versus estimated hours to complete. Revenue from post-contract customer support
agreements, or maintenance, is recognized ratably over the term of the related
agreements, which typically have a 12-month term. Billings in advance of revenue
recognition are recorded as unearned revenue.

    Although we have experienced revenue growth, we have incurred significant
costs to develop our products and to recruit and train personnel. As a result,
we have incurred significant losses since inception, and as of December 31,
1999, had an accumulated deficit of approximately $16.2 million. We

                                       19

believe our success depends on, among other things, rapidly increasing our
customer base, further developing our B2Bi products and introducing creative
product enhancements into the marketplace. We intend to continue to invest
heavily in sales and marketing and research and development. We therefore expect
to continue to incur substantial operating losses for the foreseeable future.

    In September 1999, we completed the sale of our Educational Services
division, which provided software training services. This disposition resulted
in a gain on sale of $2.6 million. In March 2000, we completed the sale of our
FAB Solutions division, which provided manufacturing software solutions for the
semiconductor industry. This disposition resulted in an estimated gain on sale
of approximately $4.0 million. Both of these divisions are treated as
discontinued operations, and accordingly their results of operations are
presented as income (loss) from discontinued operations for all periods
presented.

YEARS ENDED DECEMBER 31, 1997, 1998 AND 1999

    REVENUE

    TOTAL REVENUE.  Total revenue was $11.6 million in 1997, $11.8 million in
1998 and $20.1 million in 1999, representing increases of 1.6% from 1997 to 1998
and 70.6% from 1998 to 1999. Four customers in 1997, two customers in 1998 and
two customers in 1999 individually accounted for over 10.0% of our total revenue
in each of those fiscal years. In the aggregate, these customers accounted for
65.7% of total revenue in 1997, 36.2% of total revenue in 1998 and 46.1% of
total revenue in 1999.

    LICENSE.  Our license revenue was $1.5 million in 1997, $908,000 in 1998 and
$5.3 million in 1999, representing a decrease of 41.3% from 1997 to 1998 and an
increase of 478.2% from 1998 to 1999. The

                                       20

decrease in 1998 was due primarily to a shift in focus of our sales and
marketing staff from our C++ line of products, which constituted the majority of
our license revenue in 1997, to our OpenBusiness product line. This OpenBusiness
suite of products serves an emerging market, which results in longer sales
cycles than our C++ products. As a result, the increase in 1999 was due
primarily to increased market acceptance of our OpenBusiness product line and
the success of our earlier marketing efforts.

    SERVICE.  Our service revenue was $10.1 million in 1997, $10.9 million in
1998 and $14.9 million in 1999, representing increases of 8.2% from 1997 to 1998
and 36.7% from 1998 to 1999. These increases were due primarily to our ability
to sell additional services to existing customers, attract new customers and
increase the size of our professional services engagements. In addition, the
increase in 1999 was due, in part, to additional development projects utilizing
our OpenBusiness products. Service revenue as a percentage of total revenue was
86.7% in 1997, 92.3% in 1998 and 73.9% in 1999.

    COST OF REVENUE

    LICENSE.  Cost of license revenue consists primarily of distribution and
order fulfillment costs, product media and packaging and documentation. Our cost
of license revenue was $1.0 million in 1997, $714,000 in 1998 and $924,000 in
1999, representing a decrease of 26.2% from 1997 to 1998 and an increase of
29.4% from 1998 to 1999. The decrease in cost of license revenue in 1998 was due
primarily to a shift in product mix to our OpenBusiness products, which resulted
in lower license revenue. The increase in cost of license revenue in 1999 was
due primarily to increased revenue from licenses of our OpenBusiness products.
As a percentage of license revenue, cost of license revenue was 62.6% in 1997,
78.6% in 1998 and 17.6% in 1999. The percentage decrease in 1999 was due
primarily to our relatively fixed production and distribution costs being spread
over a larger revenue base.

    SERVICE.  Cost of service revenue consists primarily of direct labor costs
of our professional service group. Our cost of service revenue was $6.8 million
in 1997, $7.4 million in 1998 and $10.4 million in 1999, representing increases
of 9.0% from 1997 to 1998 and 40.8% from 1998 to 1999. The increases in cost of
service revenue was due primarily to an increase in the number of personnel from
43 in January 1997 to 73 in December 1999 to support the increase in service
revenue. As a percentage of service revenue, cost of service revenue was 67.6%
in 1997, 68.1% in 1998 and 70.1% in 1999. These increases are due to the use of
higher cost outside contractors. Due to the cost of recruiting personnel with
our desired skill sets, we may choose to carry under-utilized personnel for
short periods of time rather than reduce the size of our service organization.
This approach may cause our cost of service revenue as a percentage of service
revenue to vary significantly in the future, especially on a quarterly basis.

    OPERATING EXPENSE

    SALES AND MARKETING.  Sales and marketing expense consists primarily of
salaries, commissions, bonuses, recruiting costs, travel, marketing materials
and trade shows. Sales and marketing expense was $2.9 million in 1997,
$3.7 million in 1998 and $6.8 million in 1999, representing increases of 29.7%
from 1997 to 1998 and 82.5% from 1998 to 1999. The increases in sales and
marketing expense were related primarily to increased hiring and higher
commissions and bonuses. In addition, we increased our spending on trade shows
and other marketing activities to increase awareness of our OpenBusiness
products. Sales and marketing expense was 24.6% of total revenue in 1997, 31.4%
of total revenue in 1998 and 33.6% of total revenue in 1999. We intend to invest
substantial resources to expand our selling efforts and to execute marketing
programs that will enhance awareness of our products and services. As a result,
we expect sales and marketing expense to increase significantly in the future.

    RESEARCH AND DEVELOPMENT.  Research and development expense consists
primarily of personnel and related expenses and the equipment and software
required to develop, test and enhance products. Research and development expense
was $1.8 million in 1997, $1.8 million in 1998 and $4.1 million in 1999,
representing increases of 0.5% from 1997 to 1998 and 125.0% from 1998 to 1999.
The increase

                                       21

from 1998 to 1999 was due primarily to increases in our research and development
personnel dedicated primarily to the development of our OpenBusiness products
and related compensation expense. Research and development expense was 15.5% of
total revenue in 1997, 15.4% of total revenue in 1998 and 20.2% of total revenue
in 1999. We believe that continued investment in research and development is
vital to our future, and we plan to accelerate the development of new products.
As a result, we expect to continue to increase our research and development
expenditures.

    GENERAL AND ADMINISTRATIVE.  General and administrative expense consists
primarily of salaries and other related costs for finance, human resources and
other administrative personnel, as well as accounting, legal and other
professional fees. General and administrative expense was $3.0 million in 1997,
$2.8 million in 1998 and $4.0 million in 1999, representing a decrease of 5.3%
from 1997 to 1998 and an increase of 40.9% from 1998 to 1999. The increase in
1999 was related primarily to increased personnel-related costs in
administrative functions, including information technology, human resources and
finance and accounting, to support the growth of our business. General and
administrative expense was 25.5% of total revenue in 1997, 23.8% of total
revenue in 1998 and 19.6% of total revenue in 1999, reflecting increasing
revenue. We expect general and administrative costs to increase in the future,
as we expect to add personnel to support our expanding operations, to incur
additional costs related to the growth of our business and to incur the ongoing
costs associated with being a public company.

    NONCASH STOCK COMPENSATION.  During 1999, we recorded $2.0 million of
deferred stock compensation in connection with stock options issued to
employees. This charge represents the difference between the fair value of the
options on the date of grant, based on an independent appraisal commissioned by
the Company, and the exercise price of the options. The deferred stock
compensation is being amortized over the four-year vesting period of the related
options. As a result, $337,000 of noncash stock compensation expense was
recognized during 1999, $105,000 of which was attributed to discontinued
operations. We did not incur any stock-based compensation expense prior to 1999.
We expect to incur noncash charges in the future relating to stock option grants
in 1999 and the first quarter of 2000.

    INTEREST EXPENSE

    Interest expense was $56,000 in 1997, $249,000 in 1998 and $642,000 in 1999.
The increases were due primarily to approximately $3.0 million of subordinated
indebtedness incurred in June 1998. We plan to use a portion of the proceeds
from this offering to repay this subordinated indebtedness in its entirety.

    DISCONTINUED OPERATIONS

    In September 1999, we completed the sale of our Educational Services
division for $2.9 million, resulting in a gain on sale of $2.6 million. In
addition, in March 2000, we sold our FAB Solutions division, resulting in an
estimated gain on sale of approximately $4.0 million. The results of operations
for both Educational Services and FAB Solutions are reported as discontinued
operations for all periods presented.

    INCOME TAXES

    No provision for income taxes was recorded in 1998 or 1999, as we incurred
net losses. During 1997, we recognized a tax benefit of $214,000 related to the
change in our deferred tax position from a net deferred tax liability to a net
deferred tax asset, which was completely offset by a valuation allowance.

QUARTERLY RESULTS OF CONTINUING OPERATIONS

    The following table sets forth certain unaudited quarterly financial data

    Our total revenue has generally increased during each of the eight quarters
presented. The increases in license revenue over the periods presented are
related primarily to market acceptance of our OpenBusiness Infrastructure
Platform. We have historically experienced stronger demand for our products and
services during the fourth quarter and weaker demand in the first quarter. We
expect to continue to experience this seasonal pattern. We experienced a
significant increase in license revenue during the quarter ended December 31,
1999 as a result of a transaction with one of our largest customers. This
resulted in license revenue accounting for 41.4% of total revenue for the
quarter. Because license revenue typically carries a higher margin percentage
than service revenue, our gross profit percentage for the quarter ended
December 31, 1999 was significantly above our historical levels. Due to the
difference in gross profit percentage, or gross margin, between license and
service revenue, our overall gross margin is heavily dependent on our mix of
revenue. Specifically, we experience a higher gross margin in quarters where
license revenue is a larger percentage of total revenue and a lower gross margin
in quarters where license revenue is a relatively smaller percentage of our
total revenue. Our cost of license revenue is relatively fixed and does not vary
significantly based on license revenue volume. Our operating expense has
continued to increase as we have expanded our operations, especially in sales
and marketing and research and development.

LIQUIDITY AND CAPITAL RESOURCES

    Since inception, we have financed our operations through private sales of
common and preferred stock, resulting in net proceeds from inception to
December 31, 1999 of $16.6 million, and, to a lesser extent, through bank loans,
subordinated indebtedness and equipment leases. As of December 31, 1999, we had
$4.7 million in cash and short-term investments and $4.9 million in working
capital.

    Net cash used in operating activities was $1.6 million in 1997,
$3.3 million in 1998 and $8.3 million in 1999. Net cash flows from operating
activities in each period reflect increasing losses from continuing operations.
In addition, the net cash flow from operating activities in 1999 was affected by
a significant increase in accounts receivable.

    Net cash used in investing activities was $1.0 million in 1997, $645,000 in
1998 and $1.6 million in 1999. Cash used in investing activities reflects
purchases of property and equipment, primarily computer equipment, and purchases
of marketable securities. Our capital expenditures are primarily related to
supporting the increase in the number of our personnel. Therefore, we expect our
capital expenditures to continue to increase in the future. At December 31,
1999, we had no material commitments for capital expenditures.

    Net cash used in financing activities was immaterial in 1997. Net cash
provided by financing activities was $13.7 million in 1998. In 1998, cash was
primarily generated by private sales of preferred stock and issuance of debt.
Net cash used in financing activities was $289,000 in 1999, which was primarily
a result of payments for the redemption of common stock.

    In September 1999, we received $2.9 million in net proceeds from the sale of
our Educational Services division, and in March 2000, we received approximately
$5.0 million in proceeds net of related expenses and escrowed amounts from the
sale of our FAB Solutions division. An additional $800,000 was placed in escrow
until March 2001 for satisfaction of indemnification claims against us which may
arise in connection with the sale of our FAB Solutions division.

    As of December 31, 1999 our financing arrangements consisted of:

    - $3.0 million of indebtedness, which has an effective interest rate of
      approximately 15.2% and matures in June 2001;

    - a $5.0 million revolving line of credit, which had no outstanding balance;

                                       24

    - a 36-month equipment financing note in the original amount of $438,000,
      which had an outstanding balance of $357,000 and matures in 2002; and

    - various equipment leases totaling $412,000.

    Borrowings under the revolving line of credit are limited to a borrowing
base calculation and bear interest at prime rate plus 0.75%. At December 31,
1999, we were not in compliance with one of the financial covenants on the
revolving line of credit and, as such, we obtained a waiver of the noncompliance
from the bank through February 29, 2000. We are currently negotiating an
amendment to the revolving line of credit to modify the covenants; however,
there can be no assurance that we will be successful in these efforts. The
$3.0 million senior subordinated note and the equipment financing note contain
cross-default provisions to the revolving line of credit. As a result, all three
have been reclassified to current liabilities. The equipment financing note
bears interest at a rate of 11.0%.

    We expect to experience significant growth in our operating expense. In
particular, we would expect sales and marketing and research and development
expense to increase substantially in support of our OpenBusiness product line.
As a result, we expect to continue to generate operating losses. In addition, we
may use our cash to fund acquisitions, purchase new technologies or acquire
complementary product lines. We believe that the net proceeds of this offering,
together with our existing working capital immediately prior to this offering,
will be sufficient to fund our operations for at least the next twelve months.
We cannot be sure that we will be able to obtain this additional financing or
that, if we can, the terms will be acceptable to us.

    As of December 31, 1999, we had net operating loss carryforwards for federal
income tax reporting purposes of $10.4 million that expire in various amounts
beginning in 2009. Federal income tax laws contain provisions that limit the use
in any future period of net operating losses and credit carryforwards upon the
occurance of various events, including a significant change in ownership
interests. We had net deferred tax assets, including our net operating loss
carryforwards and tax credits, of $4.0 million as of December 31, 1999. To
reflect the uncertainty of whether we will be able to use the benefit of these
net operating loss carryforwards, a valuation allowance has been recorded for
the entire net deferred tax asset. See Note 5 of the notes to the financial
statements.

RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

    In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities," which establishes accounting and reporting
standards for derivative instruments and hedging activities. SFAS 133, as
amended, is effective for all quarters in fiscal years beginning after June 15,
2000. We do not currently utilize derivative financial instruments. Therefore,
we do not expect that the adoption of SFAS 133 will have a material impact on
our results of operations or financial position.

    In December 1998, the AICPA issued SOP 98-9, "Software Revenue Recognition
with Respect to Certain Arrangements." This SOP requires recognition of revenue
using the "residual method" in a multiple element arrangement when fair value
does not exist for one or more of the delivered elements in the arrangement.
Under the "residual method," the total fair value of the undelivered elements is
deferred and subsequently recognized in accordance with SOP 97-2. We did not
have a material change to our accounting for revenue as a result of the
provisions of SOP 98-9.

    In December 1999, the Securities and Exchange Commission issued SAB
No. 101, which summarizes some of the staff's view in applying generally
accepted accounting principles to revenue recognition in financial statements.
We must comply with SAB 101 beginning with the quarter ended June 30, 2000. We
continue to evaluate the impact that SAB 101 will have on our timing of revenue
recognition in future periods. Based on our initial evaluation, we believe SAB
101 will not have a material impact on our future results of operations.

                                       25

QUALITATIVE AND QUANTITATIVE DISCLOSURES ABOUT MARKET RISK

    We develop products in the United States and market our products in North
America, Europe and Asia. As a result, our financial results could be affected
by factors such as changes in foreign currency exchange rates or weak economic
conditions in foreign markets. Substantially all of our sales are currently made
in U.S. dollars, and a strengthening of the dollar could make our products less
competitive in foreign markets. Our interest income is sensitive to changes in
the general level of U.S. interest rates, particularly since the majority of our
investments are in short-term instruments. Due to the short-term nature of our
investments, we believe that there is no material risk exposure. All of our
credit facilities, with the exception of our revolving credit facility, bear
interest at fixed rates. Because we had not utilized our revolving credit
facility through December 31, 1999, our interest expense for the periods
presented was not subject to fluctuations based on changes in the general level
of U.S. interest rates. Therefore, no quantitative tabular disclosures are
required. To the extent that we utilize our revolving credit facility in the
future, future interest expense could be subject to fluctuations based on the
general level of U.S. interest rates.

INDUSTRY BACKGROUND

    THE EMERGENCE OF THE NEW B2B BUSINESS MODEL

    The Internet has emerged as a powerful new medium for communication and
commerce by fundamentally changing B2B interactions. We believe that
organizations have adopted the Internet as a new business platform in three
distinct phases. In the first phase, or "brochureware" phase, organizations
sought to quickly establish a presence on the Internet by creating websites that
provided online access to information about a company's products, services and
operations. In this first stage, organizations began to utilize the
communication benefits of the Internet, but generally failed to embrace the
Internet as a viable commerce and distribution channel. In the second phase, or
"consumer e-commerce" phase, early adopters of e-commerce technology designed
and implemented basic order entry websites so consumers could purchase goods or
services online. Today, in the third phase, or "B2B" phase, escalating
competitive pressures, shifting supplier relationships and diverse customer
demands are forcing organizations of all sizes to quickly embrace a new B2B
business model. This new model requires a higher level of business process
integration in which multiple customers, suppliers and other trading partners
transact business electronically in real-time over the Internet. We believe
organizations will not be able to effectively compete in today's global markets
without rapidly embracing this new B2B business model.

    According to Forrester Research, revenue generated from B2B e-commerce will
grow from $406 billion in 2000 to $2.7 trillion in 2004. Forrester Research also
estimates that B2B e-commerce will account for more than 90% of U.S. e-commerce
transactions by 2004. To participate in this new market opportunity, we believe
organizations will be required to implement B2Bi software. This software enables
B2B e-commerce by integrating business processes and related information
technology systems of multiple customers, suppliers and other trading partners.
As a result, businesses are spending heavily to purchase B2Bi software in order
to transact business effectively over the Internet.

                                       27

The Delphi Group forecasts revenues from B2B e-commerce software and services to
grow from $5 billion in 1999 to $40 billion in 2002.

    LIMITATIONS OF EXISTING B2B INTEGRATION SOLUTIONS

    Over the last decade, organizations have invested billions of dollars in
custom and packaged software applications to improve and integrate internal
information technology systems. These applications frequently reside on
different hardware platforms and utilize varying data formats and communications
standards. In addition, these applications were not designed to communicate with
other companies' applications. To enable the emerging B2B business model,
isolated applications must be integrated not only within an organization, but
also externally with an organization's customers, suppliers and other trading
partners. For example, organizations are increasingly integrating their
inventory and order management applications with external purchasing
applications to automate the purchasing process once an order has been placed.

    Most traditional approaches to B2Bi have been unable to adequately address
the challenges of integrating multiple customers, suppliers and other trading
partners. These approaches include in-house custom solutions, electronic data
interchange, or EDI, solutions and enterprise application integration, or EAI,
solutions. Most of these solutions are delivered over private networks,
resulting in limited scalability, long implementation times and high setup and
maintenance costs.

        IN-HOUSE CUSTOM SOLUTIONS. In-house custom solutions are typically
    point-to-point solutions developed by organizations and use closed or
    proprietary technologies. These point-to-point solutions, or solutions that
    typically integrate one specific software application to another with
    inflexible code, often limit an organization's ability to easily modify
    existing integrated software applications. These custom solutions often
    require long development lead times and are typically limited to the
    application for which they were designed. As a result, custom solutions
    usually require large, expensive information technology staffs or system
    integrators to develop and maintain, and they often lack the needed
    flexibility and scalability for today's dynamic B2B business model.

        EDI SOLUTIONS. EDI represented one of the first attempts to standardize
    business-to-business interactions without the disadvantages of developing
    and maintaining in-house custom solutions. However, due to the high cost and
    lengthy time to implement and deploy EDI solutions, their benefits have been
    limited typically to large organizations. In addition, because EDI is based
    on point-to-point integration, fixed data formats and batch processing, it
    limits organizations' ability to quickly respond to changing business
    demands and to scale to large numbers of organizations. Therefore, EDI
    solutions are often too time consuming, inflexible and expensive to
    effectively solve today's rapidly evolving B2Bi challenges.

        EAI SOLUTIONS. EAI solutions have been designed to effectively integrate
    systems within an enterprise, but typically do not provide the open and
    scalable inter-business integration that is critical for successful B2Bi.
    While EAI solutions can be extended to integrate external customers,
    suppliers and other trading partners, to do so often requires all parties to
    implement a common integration architecture. As organizations develop their
    new B2B business models and rapidly expand their B2B relationships,
    requiring a common integration architecture for all participants has become
    increasingly difficult. In addition, EAI solutions often have difficulty
    integrating the applications of a diverse set of B2B partners because many
    corporate firewalls do not readily recognize EAI communications protocols.
    As a result, EAI solutions are typically too inflexible to provide the
    necessary level of integration to fully achieve the benefits of B2Bi.

                                       28

    THE OPPORTUNITY FOR A NEW INTERNET-BASED B2BI SOLUTION

    We believe that by utilizing the Internet there is a significant opportunity
to provide organizations with a cost-effective B2Bi solution. This solution
should enable business process integration among customers, suppliers and other
trading partners, thereby facilitating the transition to a new B2B business
model. This solution should provide the flexibility and scalability to adjust to
dynamic business needs and allow organizations to offer their B2B partners the
ability to exchange information and conduct transactions in real-time,
regardless of their installed technology infrastructure. In addition, because
many organizations lack the expertise or resources to design and deploy new B2Bi
solutions, we believe a B2Bi solution should be supported by an experienced
professional services organization.

THE OBJECTSPACE SOLUTION

    We provide an Internet-based B2Bi solution that enables organizations to
easily and rapidly integrate business applications within and across
organizations. Our software allows organizations to link their business
processes, sharing services, conducting transactions and exchanging information
in real-time, with customers, suppliers and other trading partners. Our
OpenBusiness solution provides a robust, easy to configure integration platform
that ensures reliable, secure integration of complex, dynamic business
applications and scales to accommodate large numbers of customers, suppliers and
other trading partners. We believe our OpenBusiness solution allows our
customers to integrate business processes with trading partners with fewer
alterations to their existing software applications than the current
alternatives require. Through the use of XML and support for a broad range of
additional communications standards, our solution provides a high level of
interoperability among disparate applications. As a result, unlike other B2Bi
solutions, our OpenBusiness solution allows multiple customers, suppliers and
other trading partners to successfully integrate otherwise incompatible software
applications without significant reprogramming or adopting the same
communications standards. In addition, to help our customers adopt a new B2B
model and implement our B2Bi solutions, we provide a wide range of professional
services, including strategic planning, architectural design, project management
and implementation services.

    Our OpenBusiness solution provides the following business benefits to our
customers:

    ENABLES NEW B2B BUSINESS MODELS.  Our easy-to-use, scalable solution allows
our customers to rapidly adopt new B2B models that require seamless business
process integration. By improving, streamlining and automating B2B processes and
information flows, our solution enables organizations to capitalize on the
significant benefits associated with integrating customers, suppliers and other
trading partners in dynamic Internet-based B2B communities. These benefits
include enhanced revenue opportunities by enabling organizations to introduce
products to market more quickly and to provide new services to their customers.
In addition, organizations are able to increase operating efficiencies by
automating manual processes, efficiently managing inventories, reducing cycle
times and improving planning and forecasting capabilities.

    REDUCES TIME TO MARKET.  Our solution is designed to be easily and rapidly
deployed, permitting our customers to reduce their time to market for new
Internet-based B2B strategies. Unlike other B2Bi solutions, our OpenBusiness
solution does not require customers to modify existing applications or to adopt
a common integration technology. Therefore, customers generally need less time
to implement our OpenBusiness solution. Our solution is further differentiated
by providing easy-to-use portal software that allows our customers to further
simplify the process of integrating applications of B2B partners over the
Internet. As a result, our customers can quickly integrate their applications
with those of their customers, suppliers and other trading partners, saving
significant time and expense and speeding deployment of their B2B strategies. To
further speed time to market, we support our customers with extensive
professional services to help accelerate their implementation of B2Bi solutions.

                                       29

    LEVERAGES EXISTING TECHNOLOGY INVESTMENTS.  Over the last decade,
organizations have invested billions of dollars in custom and packaged software
applications, referred to as legacy applications. Using XML and supporting a
wide variety of other communications standards unlike other solutions, our
solution provides a high level of interoperability among legacy applications
without costly reprogramming. By eliminating reprogramming costs, organizations
are more likely to achieve broader, more extensive integration of their
disparate legacy applications, resulting in more effective B2Bi solutions.
Because our solution's integration capabilities easily extend legacy
applications to a wide range of users regardless of the user's location or
underlying infrastructure, organizations can realize greater returns on their
prior information technology investments.

OUR STRATEGY

    Our goal is to be the leading provider of B2Bi software and services that
enable organizations to develop and implement new Internet-based B2B business
models. To achieve this objective, we are pursuing the following strategies:

    EXTEND OUR PRODUCT AND TECHNOLOGICAL LEADERSHIP.  We believe we have
developed the most comprehensive B2Bi solution currently available. Our products
feature a number of different B2B software integration capabilities that utilize
XML extensively. Furthermore, we believe our solution supports more B2B
communications and data format standards than any other competing solution,
allowing us to provide improved interoperability among business processes of B2B
partners. We intend to build upon our integration technology and improve our
solution's functionality and ease of use for rapidly developing B2Bi
requirements. We also intend to continue to remain actively involved with
industry standard organizations to ensure that our OpenBusiness products
incorporate new integration technology and communications standards as they
emerge. In addition, we may seek to enhance our product leadership through
licensing or acquiring complementary technologies or businesses.

    LEVERAGE OUR EXISTING CUSTOMER BASE.  We believe our current customer base
represents a significant opportunity for additional revenues. Since 1997, we
have developed relationships with over 800 customers, of which approximately 110
have purchased licenses for our OpenBusiness Infrastructure Platform. We believe
that many of these companies are beginning to implement new Internet-based B2B
strategies, and we intend to aggressively market our solution to them. In
addition, as our customers expand and refine their Internet strategies and begin
to realize the full potential of B2Bi, we believe we can increase sales by
expanding limited deployments into enterprise-wide implementations, as well as
by selling additional OpenBusiness products.

    EXPAND SALES AND DISTRIBUTION CHANNELS.  We intend to rapidly pursue a
multi-channel, global distribution strategy by capitalizing on our direct sales
force and key relationships with system integrators, value-added resellers,
OEMs and international distributors. We intend to increase our domestic
distribution by opening additional field offices and adding sales personnel in
our existing offices. We also plan to continue to expand our indirect
distribution through alliances with additional system integrators, value-added
resellers and OEMs. We intend to increase our international distribution by
developing additional relationships with international distributors,
establishing foreign direct sales offices and creating strategic alliances with
international system integrators.

    BENEFIT FROM NETWORK EFFECTS.  As customers utilize our OpenBusiness
products to integrate their B2B partners, these B2B partners will experience the
features and benefits of our products. We have already experienced additional
sales as a result of customers recommending and exposing our products to their
networks of customers, suppliers and other trading partners. Depending on the
level of B2B integration desired, some of our customers may require their B2B
partners to use our products. We believe this network effect will increase the
demand for our products, increase our brand recognition and strengthen our
position in the B2Bi solutions market.

                                       30

    CAPITALIZE ON OUR PROFESSIONAL SERVICES CAPABILITIES.  We have established
highly successful relationships with customers by assisting them in designing,
developing and deploying B2Bi solutions. Our extensive professional services
range from strategic and architectural planning to complete integration and
deployment of our products. In addition, we will continue to extend our
professional services expertise in applying emerging standards, especially XML
standards, to create B2Bi solutions. By offering a full range of professional
services, we believe we can deepen our existing customer relationships and
foster new customer relationships, thereby creating opportunities to sell
additional OpenBusiness products.

PRODUCTS

    Our OpenBusiness products consist of three products: the OpenBusiness
Infrastructure Platform, the OpenBusiness Gateway and the OpenBusiness Portal.
Utilizing the technology developed in the OpenBusiness Infrastructure Platform,
which we first licensed in October 1997, we recently released the OpenBusiness
Gateway and OpenBusiness Portal in late March 2000. These products work together
to provide an integrated B2Bi solution that allows organizations to integrate
business processes over the Internet and to share services and exchange
information in real-time.

    The OpenBusiness solution supports many current and emerging communications
standards, including XML, HTTP, CORBA, DCOM, SSL and RMI. In addition,
OpenBusiness supports many emerging XML standards, including Open Financial
Exchange, Oasis, RosettaNet, Open Travel Association and Microsoft BizTalk.

    Our OpenBusiness product line is illustrated below:

    [The diagram of our OpenBusiness product line consists of:

    Four informational boxes arranged in a diamond pattern, each connected to an

    OPENBUSINESS INFRASTRUCTURE PLATFORM.  The OpenBusiness Infrastructure
Platform automates the exchange of information between incompatible legacy
software applications, databases and EDI software within an organization. For
example, by automatically translating between communications standards used by
different business applications, such as supply chain management and customer
relationship management applications, the Infrastructure Platform greatly
simplifies the challenge of connecting an organization's applications. The
Infrastructure Platform provides the critical foundation for integrating an
organization's disparate business applications, allowing them to be easily
extended to their external B2B partners.

    OPENBUSINESS GATEWAY.  The OpenBusiness Gateway builds upon the
functionality of the Infrastructure Platform by extending an organization's
internally integrated applications to their B2B partners over the Internet. An
organization that wants to make its internal applications accessible by its B2B
partners can use the Gateway to:

    - define which applications can be accessed;

    - manage security, defining who can access certain applications;

    - limit when and for how long each application can be accessed;

    - extend applications beyond corporate firewalls; and

    - monitor, audit and bill for the usage of each application.

    The Gateway utilizes XML to simplify the process of integrating the business
processes of B2B partners. Our XML-based approach also provides higher levels of
interoperability among disparate business applications, regardless of the
underlying communications standards, hardware platforms or operating systems.

    The Gateway can be fully integrated with the OpenBusiness Portal software,
allowing customers to establish their own website to provide quick and easy
access to their business applications.

    OPENBUSINESS PORTAL.  By leveraging the integration and access capabilities
of the Infrastructure Platform and Gateway, the OpenBusiness Portal allows
organizations to rapidly create a website to catalog business applications that
they choose to make available to their community of B2B partners.

    Organizations that establish websites using the Portal can configure and
manage the features and options of the website, including security features that
authorize portal access to their community of B2B partners. Once an organization
has created a website, any authorized partner using our Gateway product can also
provide access to their business applications on the website. This functionality
allows each member in a B2B community to easily exchange information and
services with other participants.

PRODUCT TECHNOLOGY

    Our OpenBusiness solution utilizes several key technologies to provide
scalable, robust B2B integration. These key technologies are described below:

    XML STANDARDS.  We use XML, a key standard for providing interoperability
between disparate business applications, in our OpenBusiness solution. XML is an
emerging standard for defining uniform

                                       32

data formats. XML allows "descriptive tags" to be attached to data, allowing
applications to understand the meaning and context of the data. While these
descriptive tags provide significant flexibility in how data is described,
organizations often use them to describe data differently. Many industries are
establishing groups to define industry-specific standards for the use of XML
tags.

    Our OpenBusiness solution provides support for many of the emerging industry
XML standards. With its non-intrusive architecture, our OpenBusiness solution
provides support for XML standards with minimal impact to existing business
applications. We believe this is a key in enabling integration of business
processes among B2B partners.

    NON-INTRUSIVE ARCHITECTURE.  Other B2Bi solutions typically require
organizations to make significant modifications to existing business application
source code, resulting in higher maintenance costs and lengthy time-to-market.
Our OpenBusiness products allow organizations to make existing business
applications available to other organizations over the Internet, without the
need for significant reprogramming. By minimizing the impact on existing
business applications, our B2Bi solutions generally can be implemented more
rapidly and at a lower cost than other B2Bi solutions. In addition, our
OpenBusiness products can be implemented without interfering with the normal
operation of a customer's business applications.

    OPEN STANDARDS.  Our OpenBusiness solution supports many open communications
standards, including XML, HTTP, CORBA, DCOM, SOAP, SSL and RMI. Communications
standards represent defined methods by which applications communicate
information. In addition, OpenBusiness supports many current and emerging
industry XML standards, including Open Financial Exchange, Oasis, RosettaNet,
Open Travel Association and Microsoft BizTalk. As new standards emerge, we
intend to enhance our OpenBusiness products to support these new standards,
consistent with our strategy to maintain OpenBusiness' support for open
standards.

    MULTIPLE SERVER PLATFORM SUPPORT.  Our OpenBusiness products are designed to
operate on most major server platforms, which facilitates implementing our
OpenBusiness products over a large number of B2B partners. These platforms
include Hewlett Packard HP-UX, IBM AIX, Linux, Microsoft Windows NT and Sun
Microsystems Solaris.

    ROBUST SECURITY FEATURES.  Our OpenBusiness solution contains robust
security features that permit organizations to securely transmit confidential
information over the Internet. Our software includes various forms of encryption
and access controls to ensure privacy of confidential data. In addition, because
all information sent through the OpenBusiness solution can be sent using popular
communications standards, including SSL, CORBA, DCOM, HTTP and SOAP, each of
which readily passes through corporate firewalls, our customers' business
partners are not required to modify their existing security features.

    HIGHLY SCALABLE ARCHITECTURE.  Our OpenBusiness solution has been designed
with a flexible architecture that can be scaled to allow usage by thousands of
integrated organizations operating over a geographically dispersed area in an
environment of high transaction volumes. Our OpenBusiness solution also includes
features that allow it to be readily deployed across a large number of
organizations with different hardware platforms and operating systems. In
addition, our OpenBusiness solution is designed to optimize performance in a
multi-server, multi-processor environment that can be configured by our
customers.

PRODUCT DEVELOPMENT

    We licensed our first OpenBusiness product in October 1997. Using the
technology developed in our Infrastructure Platform, we recently introduced our
Gateway and Portal products. We continue to enhance our OpenBusiness products
with particular emphasis on providing improved interoperability, functionality
and ease of use. In addition, we work closely with industry standard
organizations to

                                       33

ensure that our products incorporate emerging technology and communications
standards. Our product development organization primarily focuses on enhancing
our existing products and technologies and on developing additional products to
extend our position as a leader in the B2Bi solutions market.

    As of March 15, 2000, our product development organization consisted of 39
employees. Our product development employees typically have experience in
distributed computing, XML, Java and other advanced technologies. Our research
and development expenditures were $1.8 million in 1997, $1.8 million in 1998 and
$4.1 million in 1999. We expect to continue to invest heavily in product
development and to increase the size of our product development organization.

SERVICES

    We offer a full range of professional services to customers who are engaged
in developing, deploying and managing mission-critical applications using our
OpenBusiness products. Specifically, we assist customers in all phases of
establishing their new B2B business models, from concept development to design
and implementation. Our professional services include project planning,
architectural design, prototyping, implementation, application integration and
project management. We believe that our professional services organization plays
a key role in creating opportunities to sell our OpenBusiness products.

    As of March 15, 2000, we employed 84 professionals in our professional
services group, substantially all of whom are based in Dallas, Texas. Many of
our professional services employees have advanced degrees and/or substantial
industry experience in systems design and software architecture. We generally
charge for our professional services on a time-and-materials basis. We expect to
increase the size of our professional services group and expand the scope of the
services they offer as we continue to address the needs of domestic and
international businesses. In addition, we will continue to extend our
professional services expertise in applying emerging standards, especially XML
standards, to B2Bi solutions. Our professional services customers include
ClubCorp, EDS, General Motors, Merrill Lynch, Nokia, Nortel, PageMart and
Sprint.

    We provide training on our OpenBusiness products to customers and system
integrators through a staff of full-time, dedicated training professionals. Our
curriculum includes introductory through advanced courses on our products. We
offer many forms of training, including in-house lectures, on-site training and
customized workshops tailored to address unique requirements.

    In 1999, ClubCorp accounted for 26% of our total revenue, and General Motors
accounted for 20% of our total revenue. We expect that a small number of
customers will continue to account for a substantial portion of our revenues for
the foreseeable future.

CASE STUDIES

    The following case studies illustrate how some companies use our products to
enable new business models.

    GENERAL MOTORS/ONSTAR

    OnStar, a division of General Motors, operates several call centers to
provide GM vehicle owners with on board convenience and emergency services.

    BUSINESS CHALLENGE.  OnStar wanted to expand the functionality and breadth
of travel related services it could offer to GM car owners. OnStar decided to
create a call center service that could be accessed by the push of a button
within a car, through which a car passenger could speak with a call center agent
regarding a large variety of convenience services. Examples of these services
include providing dinner reservations, travel planning and entertainment
choices. In providing its new expanded service, OnStar was confronted with the
challenge of integrating multiple, disparate internal call center and back
office systems with external applications from services organizations, such as
restaurants and travel agencies, that provided OnStar access to additional
convenience services. Furthermore, OnStar required a flexible and scalable
solution that could easily manage increasing service and customer contact
information as well as accommodate millions of potential General Motors
customers.

    SOLUTION.  OnStar selected our OpenBusiness solution as a flexible
integration architecture to quickly integrate new call center services. Our
Infrastructure Platform enabled OnStar to efficiently integrate a wide variety
of internal applications, data bases and other business systems seamlessly into
a new web-based call center application. Our solution also reduced the time
required to integrate service offerings or applications from external service
providers into OnStar's Call Center Application. OnStar's service partners who
employ a variety of computer operating platforms and technologies were able to
provide services to OnStar without having to adopt new integration technologies
or reprogram their existing applications. Through the use of our solution,
OnStar expects to rapidly expand its service offerings and deliver these
services across a larger base of car owners in a highly efficient and
cost-efficient process.

                                       35

    GALILEO INTERNATIONAL

    Galileo International is one of the world's leading providers of global
distribution services for the travel industry.

    BUSINESS CHALLENGE.  Galileo has historically provided global distribution
services for travel agencies located throughout the world and travel suppliers,
including more than 500 airlines, 38 car rental companies, 44,700 hotel
properties and all major cruise lines. Galileo wanted to enable a new business
model by expanding the potential user base of its services over the Internet.
The challenge was to allow traditional customers such as travel agencies and
end-user corporations, as well as new classes of customers such as application
service providers and wireless communications companies, to quickly and easily
integrate travel services into their business solutions. Because Galileo's
customers typically have a broad range of disparate systems that use proprietary
or closed technologies, the challenge for Galileo was to install a
business-to-business infrastructure that could easily extend its services over
the Internet while integrating with a variety of operating platforms and
communications standards.

    SOLUTION.  Galileo implemented our OpenBusiness solution to integrate its
travel services with new delivery and communications methods. Our OpenBusiness
Infrastructure Platform simplified the process of integrating Galileo's internal
applications prior to being extended over the Internet. Galileo has initially
utilized our solution to develop a new service offering that enables travelers
to view and modify flight reservations using wireless devices, including cell
phones, personal digital assistants and two way pagers. This new distribution
channel gives Galileo the ability to access incremental customers and derive
additional revenue. In addition, Galileo intends to utilize our solution to
integrate its travel services with several application service providers and
wireless communications companies to further extend its potential base of new
Internet users.

SALES AND MARKETING

    We primarily license our OpenBusiness products and market our services in
the United States through our direct sales organization. Our direct sales
organization consists of account executives who generate sales leads in their
assigned geographic territories. In general, our direct sales force targets
large multi-national companies and other organizations that we believe, because
of their extensive supply chains, represent attractive candidates for our
OpenBusiness products. The OpenBusiness suite of products serves an emerging
market, which results in longer sales cycles than our C++ products. The sales
cycle for our OpenBusiness solution often ranges from three to six months. We
work closely with our targeted customers to analyze their B2Bi needs and to
propose an OpenBusiness solution. In many cases, our sales team works closely
with senior management to develop a solution. We currently have direct sales
offices in our Dallas, Texas headquarters and our offices in New York, New York;
San Francisco, California; Atlanta, Georgia; Reston, Virginia and Chicago,
Illinois. We intend to expand our domestic direct sales organization by opening
additional sales offices and adding sales personnel in our existing offices.

    We are in the early stages of expanding our presence in international
markets by developing relationships with additional international distributors,
establishing foreign direct sales offices and creating strategic alliances with
international system integrators. Our sales strategy also leverages both our
strategic relationships with system integrators, value-added resellers,
independent software vendors and our existing customer relationships to gain new
customers.

    We focus our marketing efforts on developing awareness of our OpenBusiness
products and generating new sales opportunities. Our marketing activities
include:

    - participating in seminars, conferences and trade shows;

    - joint marketing campaigns with our existing business partners;

                                       36

    - advertising in industry and other publications; and

    - creating new strategic relationships.

    We intend to significantly increase our sales and marketing expenses to
increase awareness of our OpenBusiness products.

STRATEGIC ALLIANCES

    To promote market penetration and enhance development of our products, we
have formed the following strategic alliances:

    SYSTEM INTEGRATION ALLIANCES.  To increase market penetration of our
products, we have established strategic relationships with several professional
services organizations and system integrators, including EDS, Origin Technology
in Business and Perot Systems. These non-exclusive relationships provide us with
an indirect channel to market our OpenBusiness products to a substantial number
of potential customers and access to broad-based technical expertise. These
system integrators also give us feedback on our products, which we use to
improve subsequent releases. We are aggressively pursuing additional
relationships with system integrators who offer us opportunities to expand into
geographic and/or industry markets more rapidly or who provide us with
additional market or technological expertise.

    TECHNOLOGY ALLIANCES.  To make use of standards in the areas of business
data interchange, e-commerce transaction support, distributed computing security
and authentication, we continue to maintain relationships with key technology
providers, such as HP, Microsoft, Novell and Sun Microsystems.

COMPETITORS

    The market for Internet-based B2Bi solutions is new and evolving, highly
competitive and subject to rapid technological change. In addition, we believe
the market for these solutions will become more competitive in the near future.
Increased competition could significantly reduce our future revenue and increase
our operating losses due to price reductions, lower gross margins or lost market
share. We are subject to current or potential competition from other B2Bi
vendors, internal information technology departments, EAI software vendors and
other software vendors.

    B2BI VENDORS.  We face direct competition from other B2Bi solution providers
who focus on various aspects of B2B integration. These vendors include
OnDisplay, Software Technologies Corporation and webMethods.

    INTERNAL INFORMATION TECHNOLOGY DEPARTMENTS.  Potential customers' internal
information technology departments may have developed or be in the process of
developing software that solves some of the same problems that our OpenBusiness
products solve. In those cases, we may have difficulties licensing our
OpenBusiness products to them.

    EAI SOFTWARE VENDORS.  While EAI software vendors generally do not compete
directly with us, they may in the future expand their products or add
functionality to their existing products which could put them in competition
with our OpenBusiness products. These vendors include CrossWorlds Software, New
Era of Networks and Vitria Technology.

    OTHER SOFTWARE VENDORS.  We may face future competition from large, well
established software vendors, such as Microsoft or Oracle, if they decide to
develop products that compete with our products or acquire one of our existing
or future competitors.

    Many of our existing and potential competitors have better brand
recognition, longer operating histories, larger customer bases and greater
financial, technical, marketing and other resources than us.

                                       37

As a result, they may be able to leverage these advantages to gain market share
from us. In addition, they may be able to respond more effectively than we can
to changing technologies, conditions or customer demands, especially during
market downturns.

    We believe the principal competitive factors in the B2Bi solutions market
include:

    - interoperability with existing applications, hardware platforms, operating
      systems and communications standards;

    - product functionality, quality, performance and price;

    - speed and ease of implementation;

    - support for emerging XML standards; and

    - quality and breadth of professional services.

    Although we believe our OpenBusiness solution generally competes favorably
with respect to these factors, the Internet-based B2Bi solutions market is new
and rapidly evolving. Therefore, we may not be able to maintain our competitive
position against existing and future competitors, especially those that have
greater financial, technical, marketing and other resources than us.

PROPRIETARY RIGHTS

    Our success is dependent upon protecting our proprietary technology. To do
this, we rely on a combination of contractual provisions and copyright, trade
secret, trademark and patent laws. In addition, we also maintain confidentiality
procedures to protect our proprietary information and intellectual property
rights. As part of our confidentiality procedures, we generally enter into
non-disclosure agreements with our employees, contractors and strategic
partners.

    We also enter into license agreements for our technology, documentation and
other proprietary information. Our customer licenses are generally
non-transferable, perpetual and prohibit reverse engineering our products. Our
OEM licenses are generally non-transferable, last from one to three years and
prohibit reverse engineering our products. A few of our agreements contain
provisions that, under some circumstances, would allow third parties to obtain
the source code for our software. A limited number of our agreements allow third
parties to license the source code for our software. We have entered into an
agreement with Tivoli, a subsidiary of IBM, that grants Tivoli the right of
first refusal to buy a portion of our object and source code that is included in
our OpenBusiness Infrastructure Platform, together with subsequent enhancements
and error connections for that code. This agreement could inhibit us from
selling our company or that code to a third party.

    We currently hold a trademark registration in the United States for the name
"ObjectSpace" and have applied for a trademark registration in the United States
for the name "OpenBusiness." In addition, as of March 15, 2000, we have 17
pending patent applications for technology related to our OpenBusiness product
line. While we are not aware that our products, trademarks, copyrights or other
proprietary rights infringe the proprietary rights of third parties, it is
possible that our patents, copyrights or trademarks could be challenged and
invalidated. Further, we expect that software companies will increasingly be
subject to infringement claims as the number of products and competitors in our
industry segment grows and the functionality of products in different industry
segments overlaps. From time to time, we hire or retain employees or consultants
who have worked for independent software vendors or other companies developing
products similar to those offered by us. Those prior employers may claim that
our products are based on their products and that we have misappropriated their
intellectual property. Any claims of that variety, with or without merit, could
cause a significant diversion of management attention, result in costly and
protracted litigation, cause product shipment delays or require us to enter into
royalty or licensing agreements. Those royalty or

                                       38

licensing agreements, if required, may not be available on terms acceptable to
us or at all, which would have a material adverse affect on our business.

    Policing unauthorized use of our products is difficult, particularly because
the global nature of the Internet makes it difficult to control the ultimate
destination or security of software or other data transmitted. In addition,
existing copyright, trade secret, trademark and patent laws afford only limited
protections. Effective protection of intellectual property rights may be
unavailable or limited in certain countries, because the laws of some foreign
countries do not protect our proprietary rights to the same extent as do the
laws of the United States. While we are unable to determine the extent to which
piracy of our software exists, we expect software piracy to be a persistent
problem. Furthermore, it is possible that our competitors will adopt product or
service names similar to ours, which could hinder our ability to protect our
intellectual property and possibly lead to customer confusion. Overall, the
protection of our proprietary rights may not be adequate and our competitors may
independently develop similar technology.

EMPLOYEES

    As of March 15, 2000, we employed 190 full-time employees in our current
operations, including 30 in sales and marketing, 84 in professional services, 39
in research and development and 37 in administration and finance. We also employ
varying numbers of independent contractors and consultants to support our
professional services and research and development activities. Our future
success will depend in part on our ability to attract, retain and motivate
highly qualified technical and management personnel, for whom competition is
intense. None of our employees are represented by a collective bargaining
agreement, and we have never experienced a strike or similar work stoppage. We
consider our relations with our employees to be good.

FACILITIES

    Our principal executive and corporate offices currently occupy approximately
60,000 square feet in Dallas, Texas pursuant to leases expiring in March 2003.
We also maintain offices for sales and support personnel in New York, New York;
San Francisco, California; Atlanta, Georgia; Reston, Virginia and Chicago,
Illinois. These offices are leased for various terms and generally consist of
less than 1,000 square feet of office space. We believe that our current
facilities are adequate through June 2000. We are currently negotiating leases
for additional space, which we believe we can obtain on commercially acceptable
terms, although we may be unable to do so.

LEGAL PROCEEDINGS

    We are not a party to any material legal proceedings.

directors will consist of three class I directors, Messrs. Bentley, Lowenthal
and Near, two class II directors, Messrs. Dove and Polley, and two class III
directors, Messrs. Norris and Glass. At each annual meeting of stockholders, a
class of directors will be elected for a three-year term to succeed the
directors of the same class whose terms are then expiring. The terms of the
current directors expire upon the election of successor directors at the annual
meeting of stockholders to be held during calendar year 2000 for the class III
directors, 2001 for the class I directors and 2002 for the class II directors.

    Each officer serves at the discretion of the board of directors and holds
office until his or her successor is elected or until his or her earlier
resignation or removal. There are no family relationships among any of our
directors or executive officers.

BOARD COMMITTEES

    We have established an audit committee and a compensation committee. The
compensation committee of our board of directors is currently composed of
Messrs. Bentley, Dove and Lowenthal.

                                       42

The compensation committee reviews and recommends to our board of directors the
compensation and benefits of our executive officers and administers our stock
option and compensation plans.

    The audit committee of our board of directors is composed of Messrs. Dove,
Lowenthal and Polley. The audit committee is governed by a charter that requires
each member of the committee to be independent. The charter also identifies the
roles and responsibilities of this committee, which include:

    - oversight of the audit process performed by our independent auditors;

    - review of the scope and the results of the audit process;

    - oversight of the integrity and accuracy of our internal and external
      financial reporting; and

    - review of our financial statements with our independent auditors.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

    Since February 1999, our compensation committee has been composed of
Messrs. Bentley, Dove and Lowenthal. Prior to February 1999, our board of
directors and Mr. Norris, our Chief Executive Officer, addressed compensation
issues. None of our executive officers has served on the board of directors or
compensation committee of any entity that has one or more executive officers
serving on our board of directors or compensation committee. None of the members
of our compensation committee is employed by ObjectSpace.

    During the year ended December 31, 1998, we paid an aggregate of $170,421 to
GCP Securities, a regional investment banking firm. Of this amount, we paid GCP
Securities $40,000 in connection with the sale by us of 571,429 shares of our
Series A preferred stock to certain investors and $130,421 in connection with
our obtaining $3.0 million of debt financing. During the calendar year ended
December 31, 1999, we paid to GCP Securities $150,355 in connection with our
sale of 2,702,703 shares of our Series B preferred stock to certain investors.
In December 1998, we issued to Growth Capital Partners, an affiliate of GCP
Securities, a warrant to purchase 234,595 shares of common stock, at an exercise
price of $1.32 per share. Mr. Lowenthal, a director, was an employee of Growth
Capital Partners from 1994 to 1999. In addition, entities affiliated with
Mr. Bentley have purchased shares of our preferred stock and have registration
rights related to their shares. See "Certain Transactions--Convertible Preferred
Stock Issuances and Registration Rights."

DIRECTOR COMPENSATION

    Directors who are not employees of ObjectSpace receive $1,000 for each board
meeting they attend. In addition, all board members are reimbursed for expenses
incurred in attending board or committee meetings.

    We have occasionally granted non employee directors options to purchase
shares of our common stock. In June 1998, we granted each of Messrs. Polley and
Lowenthal an option to purchase 42,000 shares of our common stock at an exercise
price of $1.43 per share. In December 1998, we granted Mr. Dove an option to
purchase 42,000 shares of our common stock at an exercise price of $1.43 per
share. In February 1999, we granted each of Messrs. Dove, Lowenthal and Polley
an option to purchase 28,000 shares of our common stock at an exercise price of
$1.43 per share. All of these options vest ratably over two years from the date
of their grant. In March 2000, we established our Non-Employee Director Stock
Option Plan, under which non-employee directors will receive automatic grants of
stock options. See "Management--Stock Option Plans" for a more detailed
discussion of the plan.

OPTION GRANTS IN LAST FISCAL YEAR

    The following table sets forth information regarding stock options granted
during 1999 to each of the named executive officers. The exercise price per
share of each option granted was equal to the fair market value of our common
stock on the date of grant, as determined by our board of directors. Each of
these options vests over a four-year period, with 25% vesting on each
anniversary of the award date.

(1) The percentage of total options granted to employees in the last fiscal year
    is based on options granted during 1999 to purchase an aggregate of
    3,610,958 shares.

                                       44

(2) Amounts that may be realized upon exercise of the options immediately before
    the expiration of their term, assuming 5% and 10% compound rates of
    appreciation on the market value of the common stock on the date of option
    grant over the term of the options. These numbers are calculated based on
    rules promulgated by the Securities and Exchange Commission and do not
    reflect our estimate of future stock price growth. Actual gains, if any, on
    stock option exercises and common stock holdings are dependent on the timing
    of exercise and the future performance of our common stock. We cannot assure
    you that the rates of appreciation assumed in this table can be achieved or
    that the amounts reflected will be received by the individuals.

FISCAL YEAR-END OPTION VALUES

    The following table sets forth information regarding unexercised options
held as of December 31, 1999 by our named executive officers. None of the named
executive officers exercised stock options during 1999.

    There was no public trading market for our common stock as of December 31,
1999. Accordingly, these values have been calculated on the basis of the initial
public offering price of $        per share, less the applicable exercise price
per share, multiplied by the number of shares underlying the options.

EMPLOYMENT AGREEMENTS AND CHANGE OF CONTROL ARRANGEMENTS

    None of the named executive officers has an employment agreement for any
specified term. These officers may resign or we may terminate their employment
at any time.

    We entered into an employment agreement with Mr. Norris in December 1998 and
an amendment to this agreement in March 2000. The agreement provides for an
annual base salary of $175,000, subject to increase, and expires in
December 2003. Under this agreement, Mr. Norris may continue to receive base
salary for one year after his resignation or termination if he is terminated
without cause or if he resigns for certain reasons, including a reduction or
change in his duties.

    The agreement also provides that during Mr. Norris's employment and for one
year after his employment terminates, he may not:

    - own, have an interest in or be an executive, agent or consultant for, any
      company that manufactures, distributes or sells products in North America
      that compete with the products that we provided during his employment; or

    - solicit business in competition with our company from our customers or
      potential customers with whom he had contact during the year prior to the
      termination of his employment.

    In addition, for two years following the termination of Mr. Norris'
employment, the agreement generally prohibits him from soliciting for employment
our employees and our customers' employees with whom he had contact during his
employment.

    In December 1998, we entered into an employment agreement with Mr. Glass
that was scheduled to expire in December 2003. Mr. Glass voluntarily terminated
his employment with us effective in January 2000. In addition, we entered into a
consulting agreement with Mr. Glass in February 2000. See "Certain
Transactions--Consulting Agreement" for a description of the terms of the
consulting agreement.

                                       45

    In August 1999, we entered into a letter agreement with Mr. Lipari,
providing that if we terminate Mr. Lipari's employment for any reason other than
performance or cause, he will continue to receive payments equal to six months'
base salary, his bonus and all benefits. If Mr. Lipari's employment is
terminated because of a change of control of our company, he will continue to
receive twelve months' base salary, his bonus and all benefits.

    Our 1998 Stock Option Plan and Non-Employee Director Stock Option Plan each
provide that outstanding options will become fully vested upon a change in
control of ObjectSpace. See "Management--Stock Option Plans" for a detailed
description of these provisions.

STOCK OPTION PLANS

    1994 STOCK OPTION PLAN.  Our board of directors adopted the 1994 Restricted
Stock and Stock Option Plan in September 1994 and amended and restated it in
March 1997. This plan provided for the grant of non-qualified stock options or
restricted stock to our employees. As of March 30, 2000, 62,509 shares were
issued upon the exercise of stock options granted under the plan and 1,005,318
shares were subject to outstanding options. We made no grants of restricted
stock under this plan. We no longer grant stock or options to purchase stock
under this plan.

    The compensation committee of our board of directors administers this plan
and determines who is granted options and the terms of options granted,
including the number of shares subject to individual option awards, the option
exercise price and vesting period. The term of all options granted under this
plan may not exceed ten years.

    If we are not the surviving corporation in a merger or consolidation, then
the company that does survive may substitute new option rights on terms
substantially similar to the options granted under this plan. If the surviving
corporation in a merger or consolidation does not assume the obligations under
this plan or we sell all or substantially all of our assets, then we may set a
date at least 20 days before the merger, consolidation or sale on which all of
the options outstanding under this plan will vest. If this occurs, all of the
options granted under this plan will terminate and be void after the merger,
consolidation or sale.

    A holder of options granted under this plan may not transfer his options
other than by will or the laws of descent and distribution, and only the holder
or the holder's attorney in fact may exercise the options during the lifetime of
the holder.

    This plan terminates in September 2004, unless the board of directors
terminates the plan earlier.

    1998 STOCK OPTION PLAN.  Our board of directors adopted our 1998 Stock
Option Plan in June 1998 as the successor to our 1994 Stock Option Plan. This
plan provides for the grant of incentive or non-qualified stock options or
direct stock grants to our employees. We have reserved 8,400,000 shares of
common stock for issuance under this plan. As of March 30, 2000, 276,990 shares
were issued upon the exercise of stock options, 3,613,353 shares were subject to
outstanding options and 4,509,657 shares were available for future grant.

    The compensation committee of our board of directors administers this plan
and determines who is granted options and the terms of options granted,
including the number of shares subject to individual option awards, the option
exercise price and the vesting period of options. The exercise price for
incentive stock options granted under this plan may not be less than 100% of the
fair market value of our common stock on the option grant date. However, if we
grant an option to an employee who owns greater than 10% of the combined voting
power of all of our common stock, the exercise price of the options may not be
less than 110% of the fair market value of our common stock on the option grant
date and the maximum term of the option may not exceed five years. The term of
all other options granted under this plan may not exceed ten years.

                                       46

    If we are the surviving corporation in any merger, consolidation or share
exchange, any outstanding stock options granted under this plan will apply to
the securities, cash, property or assets that our holders of common stock
receive. In the event we undergo a merger, consolidation or share exchange in
which we are not the surviving corporation or we dissolve, liquidate or sell all
or substantially all of our assets, the holder of an option under this plan will
be entitled to receive, upon the exercise of his options, the securities or
other assets that are distributed to the holders of our common stock. However,
we may cancel all options granted under this plan upon a reorganization, merger,
consolidation or share exchange in which we are not the surviving corporation or
upon a dissolution or liquidation of our company, subject to each option
holder's right to purchase the common stock underlying his options for a period
of 30 days immediately preceding the effective date of the event.

    An option under this plan will generally become fully vested upon a change
of control of our company. A change in control includes:

    - a consolidation, merger or share exchange in which we are not the
      surviving corporation, unless the holders of our common stock will hold
      the same proportion of common stock of the surviving corporation as they
      held in our company before the transaction;

    - a sale, lease or other transfer of all or substantially all of our assets;

    - approval by our stockholders of a plan to liquidate or dissolve our
      company;

    - the cessation of control of directors who were either directors at the
      time of the adoption of this plan or were nominated by at least two-thirds
      of the directors then in office who were directors at the date of the
      adoption of this plan or whose election or nomination for election was
      previously so approved;

    - certain acquisitions of 20% of the voting power of our outstanding voting
      securities by a person or group who owned less than 15% of our voting
      securities on the date this plan was adopted;

    - certain acquisitions of an additional 5% of the voting power of our
      outstanding voting securities by a person or group who owned at least 15%
      of our voting securities on the date this plan was adopted; or

    - a bankruptcy proceeding.

    A holder of an option under this plan may not transfer the option other than
by will or the laws of descent and distribution, and only the holder or the
holder's attorney in fact may exercise the option during the lifetime of the
holder. Under this plan, a holder may transfer non-qualified stock options to
immediate family members, to a trust or family partnership for the sole benefit
of immediate family members, to a tax exempt entity under Section 501(c)(3) of
the federal tax code or to a split interest trust or pooled income fund as
described in Section 2522(c)(2) of the federal tax code. The recipient of any
transfer is bound to the terms of the stock option agreement being transferred
and to the terms of this plan.

    Our board of directors may discontinue or amend this plan at any time,
subject to any required stockholder approval. This plan will terminate in
April 2008, unless the board of directors terminates the plan earlier.

    NON-EMPLOYEE DIRECTOR STOCK OPTION PLAN.  We adopted our 2000 Non-Employee
Director Stock Option Plan in March 2000 and have reserved a total of 700,000
shares of common stock for issuance under this plan. This plan provides for the
grant of non-qualified stock options to our directors who:

    - are not employed by us and have not been employed by us for three years
      prior to their election or appointment; and

                                       47

    - are not, and have not been for three years prior to their election or
      appointment, a director, officer or employee of an entity that owns more
      than 5% of any class of our common stock when considered with that
      entity's affiliates.

    Under this plan, we automatically grant each of these directors an option to
purchase 42,000 shares of our common stock on the date on which the person first
becomes a director and an option to purchase 28,000 shares of our common stock
on the date on which the person is re-elected to the board of directors. The
exercise price of options under this plan will be equal to the fair market value
of the common stock on the date of grant. The maximum term of the options
granted under this plan is ten years. The options become exercisable in two
equal installments on the first and second anniversary of the date of grant. As
of March 30, 2000, we had not granted any stock options under this plan. A
committee appointed by our board of directors administers this plan.

    If we are the surviving corporation in any merger, consolidation or share
exchange, any outstanding stock options granted under this plan will apply to
the securities, cash, property or assets that our holders of common stock
receive. In the event we undergo a merger, consolidation or share exchange in
which we are not the surviving corporation or we dissolve, liquidate or sell all
or substantially all of our assets, the holder of an option under this plan will
be entitled to receive, upon the exercise of his options, the securities or
other assets that are distributed to the holders of our common stock. However,
we may cancel all options granted under this plan upon a reorganization, merger,
consolidation or share exchange in which we are not the surviving corporation or
upon a dissolution or liquidation of our company, subject to each option
holder's right to purchase the common stock underlying his options for a period
of 30 days immediately preceding the effective date of the event.

    An option under this plan will generally become fully vested upon a change
of control of our company. A change in control includes:

    - a consolidation, merger or share exchange in which we are not the
      surviving corporation, unless the holders of our common stock will hold
      the same proportion of common stock of the surviving corporation as they
      held in our company before the transaction;

    - a sale, lease or other transfer of all or substantially all of our assets;

    - approval by our stockholders of a plan to liquidate or dissolve our
      company;

    - the cessation of control of our board of directors by directors who were
      either in office at the time of the adoption of this plan or were
      nominated by at least two-thirds of the directors then in office who were
      directors at the date of the adoption of this plan or whose election or
      nomination for election was previously so approved;

    - certain acquisitions of 20% of the voting power of our outstanding voting
      securities by a person or group who owned less than 15% of our voting
      securities on the date this plan was adopted;

    - certain acquisitions of an additional 5% of the voting power of our
      outstanding voting securities by a person or group who owned at least 15%
      of our voting securities on the date this plan was adopted; or

    - a bankruptcy proceeding.

    A holder of an option under this plan may not transfer the option other than
by will or the laws of descent and distribution, and only the holder or the
holder's attorney in fact may exercise the option during the lifetime of the
holder. Under this plan, a holder may transfer non-qualified stock options to
immediate family members, to a trust or family partnership for the sole benefit
of immediate family members, to a tax exempt entity under Section 501(c)(3) of
the federal tax code or to a split interest trust or pooled income fund as
described in Section 2522(c)(2) of the federal tax code. The recipient of

                                       48

any transfer is bound to the terms of the stock option agreement being
transferred and to the terms of this plan.

    Our board of directors may discontinue or amend the director plan at any
time, subject to any required stockholder approval. This plan will terminate in
March 2010 unless the board of directors terminates the plan earlier.

LIMITATIONS OF LIABILITY AND INDEMNIFICATION MATTERS

    Our certificate of incorporation requires us to indemnify our directors and
officers to the fullest extent permitted by Delaware law, as it now exists and
may in the future be amended. In addition, our certificate of incorporation
limits the liability of directors to the maximum extent permitted by Delaware
law. Delaware law provides that directors of a corporation will not be
personally liable for monetary damages for breach of their fiduciary duties as
directors, except liability for any of the following:

    - any breach of their duty of loyalty to ObjectSpace or its stockholders;

    - acts or omissions not in good faith or that involve intentional misconduct
      or a knowing violation of law;

    - unlawful payments of dividends or unlawful stock repurchases or
      redemptions; or

    - any transaction from which the director derived an improper personal
      benefit.

    This limitation of liability does not apply to liabilities arising under the
federal securities laws and does not affect the availability of equitable
remedies, including injunctive relief or rescission.

                                       49

                              CERTAIN TRANSACTIONS

    Since December 31, 1996, we have not been a party to any transaction or
series of transactions involving $60,000 or more and in which any director,
executive officer or holder of more than 5% of our capital stock had a material
interest, other than the transactions described below.

CONSULTING AGREEMENT

    In February 2000, we entered into a consulting agreement with Mr. Glass, a
director and our former Chief Technology Officer. Under this agreement,
Mr. Glass receives $14,583 per month for providing us consulting and advisory
services on technology issues. The agreement terminates on January 31, 2001.

    The agreement also provides that until January 2001, Mr. Glass may not:

    - own, have an interest in or be an executive, agent or consultant for, any
      company that manufactures, distributes or sells products in North America
      that compete with the products that we provided at the time that the
      consulting agreement was entered into; or

    - solicit business in competition with our company from our customers or
      potential customers with whom he had contact during the year prior to the
      date that he entered into the consulting agreement.

    In addition, the agreement generally prohibits Mr. Glass from soliciting for
employment our employees and our customers' employees with whom he had contact
during his employment with us until January 31, 2002.

PROMISSORY NOTES

    In each of December 1999 and January 2000, our board of directors approved a
$50,000 loan to Mr. Lipari, our Chief Financial Officer. In connection with the
loans, we received two promissory notes, aggregating $100,000, each bearing
interest at the rate of 6% per year. Accrued interest on the notes is due
quarterly beginning March 2000. The principal on each note is due on its third
anniversary. Mr. Lipari used the proceeds of the loans to purchase
63,000 shares of our common stock from third parties. As of March 15, 2000, the
principal amount outstanding on these notes was $100,000.

    In December 1998, our board of directors approved a $150,000 loan to
Mr. Norris, our Chairman of the Board, President and Chief Executive Officer,
and a $150,000 loan to Mr. Glass, a director and our former Chief Technology
Officer. In connection with these loans, we received a promissory note from each
individual. The principal and accrued interest on each note are due in three
annual installments, beginning 270 days after the effective date of the
registration statement containing this prospectus. As of March 15, 2000, the
entire principal amount of each note was outstanding and the effective interest
rate was 6.11%.

PUT RIGHTS

    We entered into an agreement in August 1996 with David Cook, who was then an
owner of more than 5% of our stock, under which Mr. Cook has the right to
require us to repurchase amounts of his

                                       50

common stock at $3.57 per share. Mr. Cook has required us to repurchase the
following shares under this agreement:



YEAR                                  NUMBER OF SHARES   AGGREGATE PURCHASE PRICE PAID

2000................................       50,803                   181,440


    Mr. Cook's right to require us to repurchase shares expires upon the
consummation of this offering.

RELATIONSHIP WITH GALILEO INTERNATIONAL

    In December 1998, we sold 1,351,352 shares of Series B preferred stock to
Magellen Technologies, which will automatically convert into approximately     %
of our common stock upon the closing of this offering. In 1999, we provided
professional services and our OpenBusiness products to Galileo International,
which is affiliated with Magellen Technologies. We received $1.6 million from
Galileo in 1999 and $992,000 in the period from January 1, 2000 through
March 29, 2000. Paul Bristow, a director of our company until March 2000, was
Senior Vice President of Magellen Technologies. Mr. Near, a current director of
our company, is the Senior Vice President, Internet and eCommerce of Galileo.

    In September 1998, we sold shares of Series A preferred stock to Novell for
a purchase price of $3.50 per share. In December 1998, we sold shares of
Series B preferred stock to Magellen Technologies, whose Senior Vice President
at the time was Paul Bristow. Mr. Bristow was a member of our board of directors
prior to his resignation in March 2000. In December 1998, we also sold shares of
Series B preferred stock to Cornerstone Equity Partners, Cornerstone Fund I and
Venture Fund I. Mr. Bentley, a director, is the Managing Director of each of
these entities. The purchase price for the Series B preferred stock was $3.70
per share.

    The preferred stockholders listed above have entered into agreements
pursuant to which they will be entitled to registration rights on the shares of
our common stock issuable upon the conversion of their preferred stock after
this offering. See "Shares Eligible for Future Sale--Registration Rights" for a
description of these agreements.

WARRANT ISSUANCE

    In December 1998, in connection with certain financing transactions, we
issued a warrant to Growth Capital Partners to purchase 234,595 shares of our
common stock at an exercise price of $1.32 per share. The warrant is fully
vested and immediately exercisable and will expire in December 2003.
Mr. Lowenthal, a director of our company, has a 10% beneficial interest in the
warrant and was an employee of Growth Capital Partners until December 1999.

                                       51

OPTION GRANTS

    We have granted options to some of our directors and executive officers, and
we intend to grant additional options to them in the future. See
"Management--Director Compensation," "Management--Option Grants in Last Fiscal
Year" and "Principal Stockholders."

    In addition, in October 1999, our board of directors approved the grant of a
stock option for 448,000 shares of our common stock to Paul Lipari, our Chief
Financial Officer. Half of this option vests upon the effectiveness of the
registration statement containing this prospectus. The remainder of the option
vests over a four year period, with 25% vesting on each anniversary of the award
date.

CONFLICT OF INTEREST POLICY

    All future transactions between us and our officers, directors and 10%
stockholders will be on terms no less favorable to us than could be obtained
from unaffiliated third parties. These transactions must be approved by a
majority of our independent and disinterested directors to the extent that the
amount involved in the transaction exceeds $50,000 or the aggregate amount per
director, officer or 10% stockholder exceeds $100,000.

                                       52

                             PRINCIPAL STOCKHOLDERS

    The following table sets forth information known to us regarding the
beneficial ownership of our common stock as of March 30, 2000, by:

    - each person or entity whom we know to own beneficially more than 5% of our
      common stock;

    - each of the named executive officers;

    - each of our directors; and

    - all of our directors and executive officers as a group.

    The number and percentage of shares beneficially owned is determined in
accordance with the rules of the Securities and Exchange Commission, and is not
necessarily indicative of beneficial ownership for any other purpose. Under
these rules, beneficial ownership includes any shares as to which a person has
sole or shared voting power or investment power and also any shares of common
stock underlying options or warrants that are exercisable by that person within
60 days of March 30, 2000. However, shares underlying options or warrants are
not treated as outstanding for the purpose of computing the percentage ownership
of any other person or entity. Unless otherwise indicated in the footnotes, each
person has sole voting and investment power with respect to the shares shown as
beneficially owned by that person. Percentage of beneficial ownership prior to
the offering is based on 30,258,468 shares of common stock outstanding as of
March 30, 2000, assuming the conversion of all outstanding shares of our
preferred stock into shares of common stock. Percentage of beneficial ownership
after the offering assumes       shares of common stock to be outstanding after
completion of this offering and no exercise of the underwriters' over-allotment
option to purchase up to an aggregate of       additional shares.

    Unless otherwise indicated, the address for each listed person or entity is
c/o ObjectSpace, Inc., 14850 Quorum Drive, Suite 500, Dallas, Texas 75240.

                          DESCRIPTION OF CAPITAL STOCK

    Following this offering, our authorized capital stock will consist of
95,000,000 shares of common stock, par value $0.01 per share, and 5,000,000
shares of preferred stock, par value $1.00 per share. The following summary of
certain provisions of the common stock and the preferred stock is not complete
and is qualified by our certificate of incorporation and bylaws and by the
provisions of applicable law.

COMMON STOCK

    As of March 30, 2000, assuming conversion of all shares of convertible
preferred stock into common stock, there would have been 30,258,468 shares of
common stock outstanding held by approximately 90 stockholders of record. There
will be             shares of common stock outstanding, assuming no exercise of
the underwriters' over-allotment option and no exercise of outstanding options
or warrants, after giving effect to the sale of common stock in this offering
and the automatic conversion of all of our outstanding preferred stock into
shares of common stock.

    The holders of common stock are entitled to one vote per share on all
matters to be voted upon by the stockholders and do not have cumulative voting
rights. Subject to preferences that may be applicable to any outstanding
preferred stock, the holders of outstanding shares of common stock are entitled
to receive dividends out of assets legally available at times and in amounts as
the board may determine from time to time. In the event of our liquidation,
dissolution or winding up, the holders of our common stock are entitled to share
ratably in all assets remaining after payment of liabilities, subject to prior
distribution rights of any preferred stock then outstanding. Upon the
consummation of

                                       54

this offering, the common stock will have no preemptive or conversion rights or
other subscription rights. There are no redemption or sinking fund provisions
applicable to the common stock. All outstanding shares of common stock are fully
paid and nonassessable, and the shares of common stock to be issued upon
completion of this offering will be fully paid and nonassessable. The rights,
preferences and privileges of the holders of common stock are subject to, and
may be adversely affected by, the rights of the holders of shares of any series
of preferred stock that we may designate in the future.

PREFERRED STOCK

    Upon the closing of this offering, each share of our outstanding Series A
preferred stock and Series B preferred stock will automatically convert into 2.8
shares of common stock. Under the terms of our certificate of incorporation, the
board of directors is authorized, subject to any limitations prescribed by law,
without stockholder approval, to issue shares of preferred stock in one or more
series. The board of directors would have the power to determine the rights and
privileges of each series, including voting rights, dividend rights, conversion
rights, redemption privileges and liquidation preferences. The rights of the
holders of common stock will be subject to, and may be adversely affected by,
the rights of holders of any preferred stock that may be issued in the future.
Issuance of preferred stock, while providing desirable flexibility in connection
with possible acquisitions and other corporate purposes, could have the effect
of making it more difficult for a party to acquire, or of discouraging a party
from attempting to acquire, a majority of our outstanding voting stock.

WARRANTS

    As of March 30, 2000, three warrants were outstanding to purchase an
aggregate of 434,795 shares of our common stock outstanding. In addition, we had
an outstanding warrant to purchase a number of shares of common stock equal to
$2.5 million divided by the offering price of the common stock in this offering.

    In June 1998, in connection with our securing a revolving credit facility,
we issued a warrant to Silicon Valley Bank to purchase up to 196,000 shares of
common stock at a purchase price of $.01 per share. The warrant vested and
became exercisable immediately, but the number of shares that may be purchased
under the warrant is subject to reduction upon repayment of the credit facility.
This warrant expires on June 16, 2005.

    In December 1998, in connection with certain financing transactions, we
issued a warrant to Growth Capital Partners to purchase 234,595 shares of common
stock at an exercise price of $1.32 per share. The warrant is fully vested,
immediately exercisable and will expire in December 2003.

    In December 1999, in connection with one of our licensing and professional
services transactions, we issued a warrant to General Motors to purchase that
number of shares of common stock equal to $2.5 million divided by the offering
price of the common stock in this offering. The warrant is fully vested and
immediately exercisable, expires one year after the date of this prospectus and
has an exercise price per share equal to the initial public offering price.

    In January 2000, in connection with our obtaining services from a
consultant, we issued a warrant to Avision to purchase up to 4,200 shares of
common stock at a purchase price of $8.57 per share. The warrant is fully
vested, exercisable and expires in January 2002.

ANTI-TAKEOVER EFFECTS OF PROVISIONS OF OUR CERTIFICATE OF INCORPORATION

    Our certificate of incorporation provides for the division of the board of
directors into three classes as nearly equal in size as possible with staggered
three-year terms. In addition, our certificate of incorporation provides that
directors may be removed with cause only by the affirmative vote of the

                                       55

holders of a majority of the shares of our capital stock entitled to vote. The
likely effect of the classification of the board of directors and the
limitations on the removal of directors is an increase in the time required for
the stockholders to change the composition of the board of directors.

    Upon the effectiveness of this offering, our certificate of incorporation
will provide that all stockholder actions must be effected at a duly called
meeting and not by a consent in writing. Our bylaws provide that special
meetings of the stockholders may only be called by a resolution approved by at
least a majority of the board of directors or by a holder of record of at least
25% of the outstanding shares of capital stock that are entitled to vote. Our
bylaws further provide that for a stockholder to bring business to be voted upon
at an annual or special meeting or to nominate a director, the stockholder must
comply with requirements regarding advance notice to us. The foregoing
provisions could have the effect of delaying until the next stockholders'
meeting actions which are favored by the holders of a majority of our
outstanding voting securities. These provisions may also discourage another
person or entity from making a tender offer for our common stock, because such
person or entity, even if it acquired a majority of our outstanding voting
securities, would only be able to take action as a stockholder, such as electing
new directors or approving a merger, at a duly called stockholders' meeting, and
not by written consent.

    The General Corporation Law of Delaware provides generally that the
affirmative vote of a majority of the shares entitled to vote on any matter is
required to amend a corporation's certificate of incorporation or bylaws, unless
a corporation's certificate of incorporation or bylaws, as the case may be,
requires a greater percentage. Our certificate of incorporation requires the
affirmative vote of the holders of at least two-thirds of the shares of our
capital stock that are issued and outstanding and entitled to vote to amend or
repeal various provisions of our certificate of incorporation. Our bylaws may
generally be amended or repealed by a vote of two-thirds of the board of
directors and may also be amended or repealed by the affirmative vote of the
holders of at least two-thirds of the outstanding shares of each class of stock
that is entitled to vote. The two-thirds stockholder vote would be in addition
to any separate class vote that might in the future be required in accordance
with the terms of any series of preferred stock that might be outstanding at the
time any such amendments are submitted to stockholders.

DELAWARE TAKEOVER STATUTE

    We are subject to Section 203 of the General Corporation Law of the State of
Delaware, which, in general, prohibits a Delaware corporation from engaging in
any business combination with any interested stockholder for a period of three
years following the date of the transaction in which the person or entity became
an interested stockholder. A business combination includes mergers, asset sales
and other transactions resulting in a financial benefit to the interested
stockholder. An interested stockholder is any entity or person, alone or with
affiliates and associates, who owns, or within the last three years has owned,
15% or more of the outstanding voting stock. This provision could discourage
anti-takeover attempts not approved by our Board of Directors, including
attempts that might result in a premium over the market price for shares of
common stock by our stockholders.

TRANSFER AGENT AND REGISTRAR

    The Transfer Agent and Registrar for the common stock will be American Stock
Transfer and Trust Company.

                                       56

                        SHARES ELIGIBLE FOR FUTURE SALE

    Upon completion of this offering, assuming no exercise of the underwriters'
over-allotment option, we will have an aggregate of       shares of common stock
outstanding, assuming no exercise of outstanding options or warrants. Of the
total outstanding shares, the       shares sold in this offering will be freely
tradable without restriction or further registration under the Securities Act,
except that any shares held by our affiliates, as that term is defined under the
Securities Act, may generally only be sold in compliance with the limitations of
Rule 144 as described below.

SALES OF RESTRICTED SHARES

    The remaining       shares of common stock held by existing stockholders
were issued and sold by us in reliance on exemptions from the registration
requirements of the Securities Act. Of these shares,             will be subject
to "lock-up" agreements providing that the stockholder will not offer, sell or
otherwise dispose of any of the shares of common stock owned by them for a
period of 180 days after the date of this offering. However, holders of such
restricted shares who have not been officers, directors or affiliates of our
company on or since the date of this prospectus may offer, sell or otherwise
dispose of 25% of their shares on the earlier of 90 days after the date of this
offering or on the second trading day after the first public release of our
quarterly results if the last recorded sale price on the Nasdaq National Market
for 20 of the 30 trading days ending on such date is at least twice the price
per share in the initial public offering. These stockholders may also offer,
sell or otherwise dispose of an additional 25% of their shares 135 days after
the date of this offering if the price per share of common stock has achieved
the same target level. However, Donaldson, Lufkin & Jenrette Securities
Corporation may in its sole discretion, at any time without notice, release all
or any portion of the shares subject to lock-up agreements. Donaldson, Lufkin &
Jenrette has approved pledges of up to 3,609,446 shares of common stock to
secure loans. If a default occurs under a loan, the lender may foreclose upon
and sell any pledged shares. Upon expiration of the lock-up agreements,
shares will become eligible for sale pursuant to Rule 144(k),   shares will
become eligible for sale under Rule 144 and       shares will become eligible
for sale under Rule 701.

(1) The number of shares listed may be offered, sold or traded provided that the
    last recorded sale price per share for 20 of the 30 trading days ending on
    such date is at least twice the initial public offering price per share.

    After the completion of this offering, we intend to file a registration
statement on Form S-8 under the Securities Act to register all of the shares of
common stock issued or reserved for future issuance under our stock option
plans. Based upon the number of shares subject to outstanding options as of
March 30, 2000 and currently reserved for issuance under these plans, this
registration statement would

                                       57

cover approximately 9,954,328 shares. Shares registered under the registration
statement will generally be available for sale in the open market immediately
after the 180-day lock-up agreements expire.

RULE 144

    In general, under Rule 144 as currently in effect, a person including an
affiliate, who has beneficially owned shares of our common stock for at least
one year would be entitled to sell in "broker's transactions" or to market
makers, within any three-month period, a number of shares that does not exceed
the greater of:

    - 1% of the number of shares of common stock then outstanding (which will
      equal approximately       shares immediately after this offering); or

    - the average weekly trading volume in the common stock on the Nasdaq
      National Market during the four calendar weeks preceding the filing of a
      notice on Form 144 with respect to such sale.

Sales under Rule 144 are generally subject to the availability of current public
information about ObjectSpace.

RULE 144(K)

    Under Rule 144(k), a person who was not our affiliate at any time during the
three months preceding a sale, and who has beneficially owned the shares
proposed to be sold for at least two years, is entitled to sell the shares
without having to comply with the manner of sale, public information, volume
limitation or notice filing provisions of Rule 144.

RULE 701

    In general, under Rule 701, any of our employees, directors, officers,
consultants or advisors who purchase shares from us in connection with a
compensatory stock or option plan or other written agreement before the
effective date of this offering is entitled to sell the shares 90 days after the
effective date of this offering in reliance on Rule 144, without having to
comply with the holding period and notice filing requirement of Rule 144 and, in
the case of non-affiliates, without having to comply with the public
information, volume limitation or notice filing provisions of Rule 144. However,
holders of shares that would otherwise be saleable under Rule 701 are subject to
the contractual restrictions described above which restrict the sale or
disposition of such shares for 180 days following the effective date.

WARRANTS

    As of March 30, 2000, we had outstanding warrants currently exercisable for
a total of 434,795 shares of common stock. In addition, we had an outstanding
warrant to purchase a number of shares of common stock equal to $2.5 million
divided by the offering price of the common stock in this offering. All of these
shares are restricted by the terms of the lock-up agreements.

REGISTRATION RIGHTS

    After this offering, the holders of 12,957,999 shares of common stock and
warrants to purchase common stock will be entitled to registration rights. In
addition, the holders of a warrant to purchase that number of shares of common
stock equal to $2.5 million divided by the offering price of the common stock on
the effective date of this prospectus will be entitled to registration rights.
If we propose to register any of our securities under the Securities Act, either
for our own account or for the account of other security holders exercising
registration rights, we must notify these security holders and these security
holders may be entitled to include all or part of their shares in the
registration. Further, the holders of these registration rights may require us
to file additional registration statements

                                       58

on Form S-3. The holders of 9,363,567 shares of common stock and warrants to
purchase common stock have demand registration rights under which they may
require us to use our best efforts or commercially reasonable efforts to
register shares of their common stock. All of these registration rights are
subject to various conditions and limitations, including:

    - the right of underwriters to limit the number of shares included in a
      registration;

    - our right to refuse to effect a requested registration following an
      offering of our securities, including this offering, for a period of time
      that ranges from 120 days to 180 days depending on the registration rights
      agreement;

    - in some circumstances, a minimum number of shares that must be included in
      a request for registration; and

    - in some circumstances, the requirement that a demand registration be
      underwritten.

    The underwriting agreement provides that the obligations of the underwriters
to purchase and accept delivery of the shares of common stock offered by this
prospectus are subject to approval by their counsel of legal matters concerning
the offering and to conditions that must be satisfied by us. The underwriters
are obligated to purchase and accept delivery of all of the shares of common
stock offered by this prospectus, other than those shares covered by the
over-allotment option described below, if any are purchased.

    The underwriters initially propose to offer the shares of common stock in
part directly to the public at the initial public offering price set forth on
the cover page of this prospectus and in part to dealers, including the
underwriters, at such price less a concession not in excess of $   per share.
The underwriters may allow, and such dealers may re-allow, to other dealers a
concession not in excess of $   per share. After the initial offering of the
common stock, the public offering price and other selling terms may be changed
by the representatives at any time without notice. The underwriters do not
intend to confirm sales to any accounts over which they exercise discretionary
authority.

    An electronic prospectus will be available on the website maintained by
DLJDIRECT Inc., an affiliate of Donaldson, Lufkin & Jenrette Securities
Corporation. Other than the prospectus in electronic format, the information on
this website relating to the offering is not part of this prospectus, has not
been approved or endorsed by us or the underwriters, and should not be relied on
by prospectus investors.

    We have granted to the underwriters an option, exercisable for 30 days after
the date of this prospectus, to purchase, from time to time, in whole or in
part, up to an aggregate of       additional shares of common stock at the
initial public offering price less underwriting discounts and commissions. The
underwriters may exercise the option solely to cover over-allotments, if any,
made in connection with the offering. To the extent that the underwriters
exercise the option, each underwriter will become obligated, subject to
conditions contained in the underwriting agreement, to purchase its pro rata
portion of such additional shares based on the underwriters' percentage
underwriting commitment as indicated in the above table.

    We have agreed to indemnify the underwriters against liabilities which may
arise in connection with the offering, including liabilities under the
Securities Act of 1933, or to contribute to payments that the underwriters may
be required to make.

                                       60

    We, our executive officers and directors and certain of our stockholders
have agreed, subject to certain exceptions, not to:

    - offer, pledge, sell, contract to sell, sell any option or contract to
      purchase, purchase any option or contract to sell, grant any option, right
      or warrant to purchase or otherwise transfer or dispose of, directly or
      indirectly, any shares of common stock or any securities convertible into
      or exercisable or exchangeable for common stock; or

    - enter into any swap or other arrangement that transfers all or a portion
      of the economic consequences associated with the ownership of any common
      stock;

regardless of whether any of the transactions described above are to be settled
by the delivery of common stock, or such other securities, in cash or otherwise,
for a period of 180 days after the date of this prospectus without the prior
written consent of Donaldson, Lufkin & Jenrette Securities Corporation. However,
25% of the shares of common stock subject to the restrictions described above
(other than shares owned by directors, officers or affiliates) will be released
from these restrictions if the reported last sale price of the common stock on
the Nasdaq National Market is at least twice the initial public offering price
for 20 of the 30 consecutive trading days ending on the last trading day of the
90-day period after the date of this prospectus. These shares will be released
on the later to occur of the 90-day period after the date of this prospectus and
the second trading day after the first public release of our quarterly results.
An additional 25% of the shares subject to the restrictions described above will
be released from these restrictions if the reported last sale price of the
common stock on the Nasdaq National Market is at least twice the initial public
offering price for 20 of the 30 consecutive trading days ending on the last
trading day of the 135-day period after the date of this prospectus. The
underwriters have approved pledges by each of Messrs. Cook, Glass and Norris of
up to 20% of their common stock holdings to secure loans to them. In addition,
if a default occurs, the underwriters have approved the lender's foreclosure
upon and the sale of the pledged shares. Any of these loans must mature at least
180 days after the date of this prospectus.

    In addition, during the 180-day period described above, we have also agreed
not to file any registration statement with respect to the registration of any
shares of common stock or any securities convertible into or exercisable or
exchangeable for common stock, except for registration statements on Form S-8
registering shares of common stock pursuant to our existing stock plans, without
the prior written consent of Donaldson, Lufkin & Jenrette Securities
Corporation.

    Prior to the offering, there has been no established trading market for our
common stock. The initial public offering price of the shares of common stock
offered by this prospectus will be determined by negotiation among us and the
underwriters. The factors to be considered in determining the initial public
offering price include:

    - the history of and the prospects for the markets in which we compete;

    - our past and present operations;

    - our historical results of operations;

    - our prospects for future financial performance;

    - recent market prices of securities of generally comparable companies; and

    - the general condition of the securities markets at the time of the
      offering.

    The underwriters have reserved up to       shares of our common stock to be
sold in this offering for sale to some of our employees and associates of our
employees and directors, and to other individuals or companies who have
commercial arrangements or personal relationships with us. Through this directed
share program, we intend to ensure that those individuals and companies that
have supported us, or that are in a position to support us in the future, have
the opportunity to

                                       61

purchase our common stock at the same price that we are offering our shares to
the general public. Prospective participants will not receive any investment
materials other than a copy of this prospectus, and will be permitted to
participate in this offering at the initial public offering price presented on
the cover page of this prospectus. No commitment to purchase shares by any
participant in the directed share program will be accepted until the
registration statement of which this prospectus is part is effective and an
initial public offering price has been established. The number of shares
available for sale to the general public will be reduced by the number of shares
sold through the directed share program. Any shares reserved for the directed
share program which are not so purchased will be offered by the underwriters to
the general public on the same basis as the other shares offered hereby.

    Other than in the United States, no action has been taken by us or the
underwriters that would permit a public offering of the shares of common stock
offered in any jurisdiction where action for that purpose is required. The
shares of common stock offered may not be offered or sold, directly or
indirectly, nor may this prospectus or any other offering material or
advertisements in connection with the offer and sale of any such shares of
common stock be distributed or published in any jurisdiction, except under
circumstances that will result in compliance with the applicable rules and
regulations of such jurisdiction. Persons into whose possession this prospectus
comes are advised to inform themselves about and observe any restrictions
relating to the offering and the distribution of this prospectus. This
prospectus does not constitute an offer to sell or a solicitation of an offer to
buy any shares of common stock offered in any jurisdiction in which such an
offer or a solicitation is unlawful.

    In connection with the offering, the underwriters may engage in transactions
that stabilize, maintain or otherwise affect the price of the common stock.
Specifically, the underwriters may over-allot the offering, creating a syndicate
short position. The underwriters may bid for and stabilize the price of the
common stock. In addition, the underwriting syndicate may reclaim selling
concessions from syndicate members and selected dealers if they repurchase
previously distributed common stock in syndicate covering transactions, in
stabilizing transactions or otherwise. These activities may stabilize or
maintain the market price of the common stock above independent market levels.
The underwriters are not required to engage in these activities, and may end any
of these activities at any time.

                                 LEGAL MATTERS

    The validity of the shares of common stock offered hereby will be passed
upon for us by Haynes and Boone, LLP, Dallas, Texas. Certain legal matters in
connection with the offering will be passed upon for the underwriters by
Brobeck, Phleger & Harrison LLP, Austin, Texas.

                         REPORT OF INDEPENDENT AUDITORS

To the Board of Directors

  ObjectSpace, Inc.

    We have audited the accompanying balance sheets of ObjectSpace, Inc. (the
Company) as of December 31, 1998 and 1999, and the related statements of
operations, stockholders' equity (deficit), 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 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 provide a reasonable basis
for our opinion.

    In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of ObjectSpace, Inc., at
December 31, 1998 and 1999, and the results of its operations and its 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.

1. DESCRIPTION OF BUSINESS AND BASIS OF PRESENTATION

    ObjectSpace, Inc. (the Company), was incorporated under the laws of the
State of Texas on August 17, 1992. The Company was reincorporated under the laws
of the State of Delaware on November 24, 1997. As part of this reincorporation,
the Company recapitalized its common stock to a $0.01 par value and authorized
the issuance of one million shares of preferred stock.

    The Company provides business-to-business, or B2Bi, software products that
enable organizations to easily and rapidly integrate business applications
within and across organizations over the Internet. The Company's OpenBusiness
software allows organizations to link their business processes, sharing
services, conducting transactions and exchanging information in real-time, with
customers, suppliers and other trading partners. The Company expects a
substantial portion of its license and service revenue to be generated from its
OpenBusiness products for the year 2000 and beyond.

    On January 14, 2000, the Company's Board of Directors authorized a 100%
stock dividend for stockholders of record at the close of business on
January 14, 2000. On March 11, 2000, the Company's Board of Directors authorized
a 40% stock dividend for stockholders of record at the close of business on
March 30, 2000. All share and per-share amounts in the accompanying financial
statements have been restated to give effect to these stock dividends.
Additionally, the Company increased the common shares authorized to 95,000,000
effective March 30, 2000.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

    REVENUE RECOGNITION

    Software license revenue is recognized upon execution of a contract and
delivery of software, provided that the license fee is fixed and determinable;
no significant production, modification, or customization of the software is
required; collection is considered probable by management; and vendor-specific
objective evidence exists to allow the allocation of the total fee to elements
of the arrangement. In December 1998, the AICPA issued SOP 98-9, "Software
Revenue Recognition with Respect to Certain Arrangements." This SOP requires
recognition of revenue using the "residual method" in a multiple element
arrangement when fair value does not exist for one or more of the delivered
elements in the arrangement. Under the "residual method," the total fair value
of the undelivered elements is deferred and subsequently recognized in
accordance with SOP 97-2. The Company adopted the provisions of this SOP
effective January 1, 1999. The Company did not have a material change to its
accounting for revenue as a result of the provisions of SOP 98-9.

    Revenue for consulting services performed under fixed-price contracts, which
are in excess of six months in duration, is recognized on a
percentage-of-completion method. Revenue from these contracts is recognized in
the proportion that labor hours incurred to date bear to total estimated labor
hours at completion. Anticipated losses on fixed-price contracts are recognized
when estimable. Revenue generated from consulting services performed under time
and materials agreements is recognized as services are performed and includes
reimbursement of expenses incurred in connection with the performance of
service. Maintenance contract revenue is recognized ratably over the term of the
related contract.

    ADVERTISING COSTS

    Advertising costs are expensed upon first showing. Amounts expensed were
approximately $552,000, $743,000 and $1.0 million in 1997, 1998 and 1999,
respectively.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    CASH AND CASH EQUIVALENTS

    Cash equivalents include highly liquid investments with a maturity period of
three months or less at the date of purchase. Cash equivalents are stated at
cost, which approximates fair value.

    MARKETABLE SECURITIES

    As of December 31, 1999, marketable securities consisted of investments in
corporate and government bond funds. These securities are classified as
"available for sale" since management intends to hold the securities for an
indefinite period of time and may sell the securities prior to their maturity.
The marketable securities are carried at aggregate fair value based on the
specific identification method. Available for sale securities that are
reasonably expected by management to be sold within one year from the balance
sheet date are classified as current assets.

    PROPERTY AND EQUIPMENT

    Property and equipment are recorded at cost. Equipment acquired under
capital leases is stated at the lower of the present value of minimum future
lease payments or fair value of the equipment at the inception of the lease.
Amortization of equipment acquired under capital lease is included in
depreciation expense. Depreciation of property and equipment, other than
leasehold improvements, is provided over the estimated useful lives of the
respective assets (ranging from three to seven years) using the straight-line
method. Leasehold improvements are amortized on a straight-line basis over the
shorter of the respective lease term or estimated useful life of the asset.

    OTHER ASSETS

    Other assets consist primarily of costs to obtain patents and trademarks.
The Company amortizes these costs over a period of 5 years using the
straight-line method beginning when the patent or trademark is issued.
Previously capitalized costs related to abandoned or denied patent applications
are expensed in the period when the application is abandoned or denied.

    IMPAIRMENT OF LONG-LIVED ASSETS

    The Company assesses the recoverability of its long-lived assets on an
annual basis or whenever adverse events or changes in circumstances or business
climate indicate that expected undiscounted future cash flows related to such
long-lived assets may not be sufficient to support the net book value of such
assets. If undiscounted cash flows are not sufficient to support the recorded
assets, an impairment is recognized to reduce the carrying value of the
long-lived assets to the estimated fair value. Cash flow projections, although
subject to a degree of uncertainty, are based on trends of historical
performance and management's estimate of future performance, giving
consideration to existing and anticipated competitive and economic conditions.
Additionally, in conjunction with the review for impairment, the remaining
estimated lives of certain of the Company's long-lived assets are assessed.

    SOFTWARE DEVELOPMENT COSTS

    Software development costs are accounted for in accordance with Statement of
Financial Accounting Standards No. 86 (SFAS 86), "Accounting for the Costs of
Computer Software to be Sold,

                                      F-8

                               OBJECTSPACE, INC.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
Leased or Otherwise Marketed." Under SFAS 86, capitalization of software
development costs begins upon the establishment of technological feasibility,
subject to net realizable value considerations. To date, such capitalizable
costs have not been material as the establishment of technological feasibility
of the Company's products and general release of such software have
substantially coincided. Accordingly, the Company has charged all such costs to
research and development expense. Future capitalized costs, if any, will be
amortized on a straight-line basis over the estimated lives of the products or
by the ratio of current revenue to the total of current and anticipated future
revenue, whichever expense is greater.

    STOCK-BASED COMPENSATION

    The Company has elected to follow Accounting Principles Board (APB) Opinion
No. 25, "Accounting for Stock Issued to Employees" (APB 25), and related
interpretations in accounting for its employee stock options and to follow the
disclosure-only provisions of SFAS No. 123, "Accounting for Stock-Based
Compensation." Under APB 25, compensation expense is based on the difference, if
any, on the date of grant, between the estimated fair value of the Company's
shares and the exercise price of options to purchase that stock.

    INCOME TAXES

    Deferred tax assets and liabilities are recognized for the estimated future
tax consequences of temporary differences and income tax credits. Temporary
differences are primarily the result of the differences between the tax bases of
assets and liabilities and their financial reporting amounts. Deferred tax
assets and liabilities are measured by applying enacted statutory tax rates
applicable to the future years in which deferred tax assets or liabilities are
expected to be settled or realized. Valuation allowances are established when
necessary to reduce deferred tax assets to the amount expected to be realized.
The Company has provided a full valuation allowance against its net deferred tax
assets as of December 31, 1998 and 1999.

    NET LOSS PER SHARE

    Basic net loss per share is computed based on the weighted average number of
outstanding shares of common stock during each period. The diluted per share
amount is computed using the weighted average number of common stock shares
outstanding and the common equivalent shares consisting of convertible preferred
stock, stock options, warrants and redeemable common stock using the treasury
stock and reverse treasury stock methods, if dilutive. Diluted loss per share is
the same as basic loss per share for all periods presented because the effects
of such items were anti-dilutive given the Company's losses. See Notes 10 and 11
for anti-dilutive securities that were excluded from the net loss per share
calculation.

    USE OF ESTIMATES

    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from these estimates.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    SEGMENT REPORTING

    The Company operates as a single segment and will evaluate additional
segment disclosure requirements as it expands its operations.

    COMPREHENSIVE INCOME

    Effective January 1, 1998, the Company adopted the provisions of SFAS
No. 130, "Reporting Comprehensive Income." SFAS No. 130 establishes standards
for reporting comprehensive income and its components in financial statements.
The Company's comprehensive loss is comprised of the net loss and elements of
other comprehensive income such as unrealized gains or losses on
available-for-sale securities.

    RECENT ACCOUNTING PRONOUNCEMENTS

    In June 1998, the Financial Accounting Standards Board issued SFAS No. 133,
"Accounting for Derivative Instruments and Hedging Activities" (SFAS 133).
SFAS 133, as amended, is effective for quarters beginning after June 15, 2000.
We do not currently utilize derivative financial instruments. Therefore, we do
not expect that the adoption of SFAS 133 will have a material impact on our
results of operations or financial position.

    In December 1999, the Securities and Exchange Commission issued Staff
Accounting Bulletin No. 101 (SAB 101) which summarizes certain of the staff's
view in applying generally accepted accounting principles to revenue recognition
in financial statements. The effective date of SAB 101 for the Company is the
quarter ended June 30, 2000. The Company continues to evaluate the impact that
SAB 101 will have on the timing of revenue recognition in future periods. Based
on its initial evaluation, the Company believes SAB 101 will not have a material
impact on its future results of operations.

3. MARKETABLE SECURITIES

    As of December 31, 1999, the Company's marketable securities available for
sale consisted of corporate and government bond funds. The securities had a cost
basis of $3,007,878 and a market value, as of December 31, 1999 of $3,001,082
resulting in an unrealized loss of $6,796. The securities are reflected in the
balance sheet at their fair market value. The gross unrealized losses for the
year ended December 31, 1999 have been recorded as a separate component of
stockholders' deficit. There were no marketable securities during 1997 or 1998.

5. INCOME TAXES (CONTINUED)

    The Company has federal net operating loss carryforwards of approximately
$10.4 million at December 31, 1999, which, if not utilized, will begin to expire
in 2009. Of this amount approximately $6.3 million is subject to limitation
under Internal Revenue Code Section 382. In addition, the Company has
approximately $10.5 million of state net operating loss carryforwards as of
December 31, 1999. Also, the Company has approximately $327,000 of research and
development credit carryforwards at December 31, 1999. Approximately $229,000 of
the research and development credits are subject to limitation under Internal
Revenue Code Section 383.

    At December 31, 1997, 1998 and 1999, the Company has recorded a valuation
allowance against its net deferred tax assets because management believes that,
after considering all the available objective evidence, the realization of the
assets are not reasonably assured.

computed by applying the statutory federal tax rate to the loss from continuing
operations before income taxes are as follows:

   The Company is obligated under various capital leases and noncancelable
operating lease agreements for facilities and equipment. The significant capital
leases contain bargain purchase options. During 1997, the Company entered into
four leases for office space in Dallas and Austin, all of which

8.  DEBT AND PUT WARRANTS TO PURCHASE COMMON STOCK

   As of December 31, 1999, the Company had an outstanding balance of $357,394
under a 36-month note (the Term Loan) in the original amount of $437,753 entered
into in June 1999. This fixed-term borrowing, which has an interest rate of
approximately 11.0%, is being repaid in monthly installments over the term of
the loan.

    On June 16, 1998, the Company issued a $3.0 million Senior Subordinated Note
(the Note) to a bank that had an original maturity of June 16, 2001, along with
196,000 seven-year detachable warrants to purchase common stock at $.01 per
share. The proceeds from the Note were allocated between the Note and the
warrants based on their relative fair market values at the time of issuance. A
discount of $227,075 was recorded against the face value of the Note which
represented the estimated fair value of the warrants on the date of issuance.
The carrying value of the Note at December 31, 1998 and 1999, was $2,813,925 and
$2,889,617, respectively, which is net of the unamortized discount of $186,075
and $110,383, respectively. The discount is being amortized until the maturity
of the Note, resulting in an effective interest rate of 15.2%. The principal of
the Note is payable at maturity and interest is payable

monthly based on a 12% interest rate. The Note is secured by all the assets of
the Company, but is subordinate to the Revolver and contains the same
nonfinancial covenants as the Revolver. The Company intends to use a portion of
the proceeds of this offering to repay the Note and therefore considers the
carrying value to approximate fair value.

    The number of warrants exercisable can decrease to as low as 84,000 provided
the Note is paid on or before certain dates. The noteholder has the option to
sell the warrants back to the Company (Put Warrants to Purchase Common Stock) on
either August 16, 2001, or on the occurrence of other specified events at an
amount per warrant equal to the Company's fair value per share at the put date
less the exercise price. The option to sell the warrants back to the Company
terminates upon specified events which include, the first sale of the Company's
common stock pursuant to a registration statement with, and declared effective
by the Securities and Exchange Commission which results in gross proceeds of at
least $10,000,000. The fair value of the warrants is included in redeemable
common stock and put warrants to purchase common stock in the accompanying
balance sheets. Changes in the fair value of the warrants are reflected as
adjustments to interest expense in the accompanying statement of operations. The
value of the warrants is reflected at the estimated fair value of the warrants,
based on an independent appraisal commissioned by the Company.

    The Company has a Loan and Security Agreement with a bank that provides the
Company with a $5 million revolving line of credit (the Revolver). The Company
may elect to borrow under the Revolver on a revolving or fixed-term basis.
Borrowings under the Revolver bear interest at the bank's prime rate plus .75%,
are secured by all the assets of the Company and are due on the maturity date of
the Revolver (April 7, 2000). Borrowings under the Revolver are limited to a
borrowing base equal to 80% of eligible trade receivables less any letters of
credit outstanding. As of December 31, 1999, there were $446,622 in letters of
credit outstanding which expire at various times during the year 2000. These
letters of credit were primarily used in lieu of security deposits on certain
operating and capital leases. The Company must also comply with certain
financial ratio and other nonfinancial covenants, including a prohibition on the
payment of dividends. As of December 31, 1999 the Company was not in compliance
with one of the covenants and, as such, obtained a waiver of the noncompliance
from the bank through February 29, 2000. The Company is currently negotiating an
amendment to the Revolver to modify the covenants, however, there can be no
assurance that the Company will be successful in those efforts. The Note and the
Term Loan contain cross-default provisions to the Revolver. As a result, all
three have been reclassified to current liabilities as of December 31, 1999.

9.  EMPLOYEE RETIREMENT PLAN

    The Company's 401(k) plan (PIE Investment Plan) provides retirement benefits
to eligible employees. Under the PIE Investment Plan, employees are eligible to
participate after one year of service. Participants are permitted to make salary
reduction contributions of up to 15% of their eligible compensation. While the
plan provides for discretionary contributions by the Company, no such
contributions have been made.

10. RESTRICTED STOCK AND STOCK OPTION PLAN (CONTINUED)

    The Company has a 1994 Restricted Stock and Stock Option Plan (the 1994
Plan) and a 1998 Stock Option Plan (the 1998 Plan) under which shares are
available for grant of restricted stock and stock options to employees. The 1994
Plan provides for the granting of a maximum of 2,800,000 shares of stock or
stock options with no more than 560,000 to any one employee in a single year. At
December 31, 1999, the 1998 Plan provides for the granting of a maximum of
5,180,000 shares of stock options with no limitations on grants to individual
employees. Under each plan, the stock option exercise price per share is equal
to the fair market value on the date of grant, as determined by the Board of
Directors. Options vest pursuant to vesting schedules as determined by the Board
of Directors (ranging from one to five years) and expire, if unexercised, ten
years from the date of grant. In addition, the Company issued 126,000 and 84,000
options to its nonemployee directors during 1998 and 1999, respectively. These
options have an exercise price of $1.43, vest over 2 years and have a 10 year
life. These options were issued outside of the Company's option plans.

    Stock option transactions in the Company's plans are summarized as follows:

    At December 31, 1999, there were 3,244,040 options available for future
issuance under the Company's plans.

    The Company has elected to follow APB 25 and related Interpretations in
accounting for its employee stock options because, as discussed below, the
alternative fair value accounting provided for under SFAS 123 requires use of
option valuation models that were not developed for use in valuing

employee stock options. The Company had no deferred stock compensation during
1997 and 1998. During 1999, in connection with options granted to employees to
purchase common stock, the Company recorded deferred stock compensation of
$2,036,338 of which $336,772 was recognized as expense. Of the amount recognized
$104,721 was charged to discontinued operations. This initial amount deferred
represents the difference between the fair value of the options on the date of
grant, based on an independent appraisal commissioned by the Company, and the
exercise price of the options. Although the Company's Board of Directors
believed that the exercise price per share assigned to stock options was equal
to the fair value on the date of grant, the Company concluded an independent
appraisal was necessary to validate the estimates of fair value due to the
subjective nature of such estimates. Therefore, the Company commissioned an
independent appraisal of its common stock as of October 31,1999. The appraised
value was used as a basis to estimate stock compensation on option grants during
1999 and was also used to determine the fair value of put warrants to purchase
common stock (Note 8). The deferred stock compensation is being amortized over
the vesting period of the related options, which is generally four years.

    Information regarding pro forma net loss is required by SFAS 123 and has
been determined as if the Company had accounted for its employee stock options
under the fair value method of SFAS 123. The fair value for these options was
estimated at the date of grant using a Black-Scholes option pricing model with
no volatility and the following assumptions: weighted average risk-free interest
rate of 6.23% in 1997, 5.35% in 1998, and 5.86% in 1999, no dividends, and a
weighted average expected life of the option of 6.0 years in 1997 and 1998, and
2.75 years in 1999.

    The Black-Scholes option valuation model was developed for use in estimating
the fair value of traded options which have no vesting restrictions and are
fully transferable. In addition, option valuation models require the input of
highly subjective assumptions. 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.

    For purposes of pro forma disclosures, the estimated fair value of the
options is amortized to expense over the options' vesting period. The Company's
pro forma information is as follows:



                                                                     YEARS ENDED DECEMBER 31,

    The pro forma disclosures include only the effect of options granted
subsequent to December 31, 1994. Accordingly, the pro forma information does not
reflect the pro forma effect of all previous stock option grants of the Company,
and thus is not necessarily indicative of future amounts until SFAS 123 is
applied to all outstanding stock options.

shares repurchased as of December 31,1999) of his shares at $3.57 per share (Put
Shares). The number of shares the Company could be required to repurchase each
quarter multiplied by $3.57 per share cannot exceed 2.5% of the preceding
quarter's revenue. The repurchase obligation of the Company terminates upon the
successful completion of an initial public offering with a pre-offering Company
valuation exceeding $100 million. With the issuance of the Series B preferred
stock, in order to conform the investor's put rights to those of the newly
issued series B preferred stock, the investor's right was amended to, in
addition to the rights described above, allow for all his Put Shares then
outstanding to be subject to repurchase at any time after January 1, 2003, if a
public offering has not occurred, or at any time that the Series A or Series B
preferred stockholders can exercise their put rights due to the Company's breach
of the preferred stockholder agreement. Additionally, the Put Shares must still
be repurchased at $3.57 per share and, upon exercise of the amended right, the
repurchase price payable shall be paid by the Company through the issuance of a
three-year note with a quarterly payment schedule and at an interest rate of
prime plus 1%. Since the repurchase of the shares is outside of the control of
the Company, the shares subject to repurchase are treated as redeemable common
stock and are presented outside of stockholders' deficit. Periodic accretions
based on the straight-line method are recorded such that the carrying value of
the Put Shares will equal the $3.57 redemption value on January 1, 2003.
Accretion to redemption value is recorded as a charge to accumulated deficit and
credited to redeemable common stock.

    REDEEMABLE CONVERTIBLE PREFERRED STOCK

    The Company issued 571,429 shares of Series A redeemable convertible
preferred stock for gross proceeds of $2.0 million on September 4, 1998, and
2,702,703 shares of Series B redeemable convertible preferred stock for gross
proceeds of $10.0 million on December 30, 1998.

DIVIDEND PREFERENCE:

    The Series A and Series B preferred stockholders are entitled to receive
noncumulative dividends in preference to the common stockholders at the rate of
$0.28 and $0.30 per share (8% of the liquidation value), respectively, per annum
provided such dividends are declared.

VOTING RIGHTS:

    Except as otherwise required by law, the Series A and Series B preferred
stockholders vote together with the common stockholders on all matters upon
which the common stockholders are entitled to vote. Each holder of preferred
stock is entitled to one vote for each share of common stock into which each
share of preferred stock could then be converted. In addition, the Series B
preferred stockholders are entitled to elect two directors to the Company's
Board of Directors.

CONVERSION RIGHTS:

    Each share of preferred stock is convertible, at the stockholder's option,
at any time after issuance into 2.8 shares of common stock. The conversion
prices at December 31, 1999 are $1.25 and $1.32 for the Series A and Series B,
respectively.

    The Series A preferred stock is automatically converted into common at the
then-applicable conversion rate (i) if the Series A stockholder holds at least
50% of the shares of Series A originally

                                      F-17

11. REDEEMABLE STOCK (CONTINUED)
issued to it and it consents to such conversion; (ii) if the Series A
stockholder converts at least 50% of the Series A shares originally issued to it
into common stock; (iii) upon a consolidation, merger, or sale of the Company at
a price per Series A preferred share of not less than $7.00; or (iv) upon the
closing of an underwritten public offering of shares of the Company at a per
share public offering price (prior to underwriter commission and expense) of not
less than $7.00 per Series A preferred share and for a total offering of more
than $20 million.

    The conversion price of the Series A preferred stock is subject to
adjustment proportionately for stock splits, stock dividends, recapitalization,
etc.

    The Series B preferred stock is automatically converted into common stock at
the then-applicable conversion rate (i) upon a consolidation, merger, or sale of
all the outstanding capital stock of the Company for cash consideration of at
least two times the then-effective conversion rate or consideration payable in
registered securities of an issuer that is publicly traded and has a market
capitalization of at least $500 million post-acquisition or (ii) upon the
closing of an underwritten public offering that results in aggregate gross
proceeds of at least $20 million.

    The conversion price of the Series B preferred stock is subject to
adjustment proportionately for stock splits, stock dividends, recapitalization,
etc. It is also subject to adjustment on a weighted average basis for sales by
the Company of its common stock at prices below the conversion price, and for
grants of stock options in excess of a specified amount prior to December 31,
2000.

REDEMPTION RIGHTS:

    If at any time the Company materially breaches the respective stockholder
agreements or if at any time after January 1, 2003, the Company has not
consummated a qualifying public offering, the Series A and Series B preferred
stockholders have the right to require the Company to repurchase the preferred
or common stock then owned by them. The repurchase price is equal to the greater
of the fair market value or a per share sale price defined as $7.40 per share
plus a 10% annual return on the original purchase price (redemption value of
$9.02 per share for the Series A preferred stockholders and $9.12 per share for
the Series B preferred stockholders). The amount payable under the repurchase
rights shall be paid by the Company issuing a three-year note with a quarterly
payment schedule and at an interest rate of prime plus 1%. Accretion towards the
maximum redemption amount using the straight-line method is charged against the
Company's additional paid-in capital and credited to the redeemable preferred.

LIQUIDATION PREFERENCE:

    In the event of the Company's dissolution, the preferred stockholders are
entitled to receive, prior to and in preference to any distribution of any of
the Company's assets and surplus funds to the common stockholders, liquidation
proceeds on a pro rata basis that is determined based on $3.50 per share plus
any declared but unpaid dividends for the Series A preferred stock and $3.70 per
share plus any declared but unpaid dividends for the Series B preferred stock.
In addition, having received their liquidation preference, the preferred
stockholders will share ratably with the common stockholders in the remaining
assets of the Company on a common share equivalent basis.

12. COMMITMENTS AND CONTINGENCIES

   One of the Company's customers has the right of first refusal to purchase
certain elements of the Company's OpenBusiness software should the Company
contract for its sale.

    The Company is subject to legal proceedings and claims that arise in the
ordinary course of its business. While management currently believes the amount
of ultimate liability, if any, with respect to these actions will not materially
affect the financial position, results of operations, or liquidity of the
Company, the ultimate outcome of any litigation is uncertain. Were an
unfavorable outcome to occur, the impact could be material to the Company.

13. DISCONTINUED OPERATIONS AND ASSETS HELD FOR SALE

    During 1999, the Company sold its Educational Services division to a third
party for approximately $2.9 million in cash. The sale produced a pretax gain of
approximately $2.6 million.

    In July 1999, the board of directors authorized the Company to sell its FAB
Solutions division. This sale was completed in March 2000. As the Company
realized a gain on the sale of FAB Solutions, the net assets of FAB Solutions
are recorded as Net Assets Held for Sale in the December 31, 1999

    Revenue from the Educational Services and FAB Solutions divisions
represented approximately $5.4 million in 1997, $5.1 million in 1998 and
$4.8 million in 1999. These revenue amounts have been eliminated from the
respective revenue lines in the accompanying statements of operations.

14. SIGNIFICANT CUSTOMERS

    The Company performs ongoing credit evaluations of its customers and
generally does not require collateral. The Company maintains an allowance for
doubtful accounts based upon the expected collectibility of all trade accounts
receivable. The losses incurred by the Company with respect to trade receivables
have not exceeded management's expectations.

    Revenue from certain of the Company's largest customers individually
exceeded 10% of the Company's revenue as follows:

15. WARRANTS

   During December 1998, in connection with certain financing transactions, the
Company issued a warrant to purchase 234,595 shares of common stock at an
exercise price of $1.32 per share. The warrant is fully vested, immediately
exercisable, nonforfeitable and will expire in December 2003.

    During December 1999, as a sales-inducement to one of its largest customers,
the Company agreed to issue one year warrants covering $2.5 million of common
stock at the Company's initial public offering price. The Company commissioned
an independent appraisal of the warrants. Based on this

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS

    The Certificate of Incorporation of ObjectSpace provides that the liability
of the directors of ObjectSpace to ObjectSpace or any of its stockholders for
monetary damages arising from acts of omissions occurring in their capacity as
directors shall be limited to the fullest extent permitted by the General
Corporation Law of the State of Delaware. This limitation does not apply with
respect to any action in which a director would be liable under Section 174 of
the General Corporation Law of the State of Delaware nor does it apply with
respect to any liability in which a director:

    - breached his duty of loyalty to ObjectSpace or its stockholders;

    - did not act in good faith or, in failing to act, did not act in good
      faith;

    - acted in a manner involving intentional misconduct or a knowing violation
      of law or, in failing to act, shall have acted in a manner involving
      intentional misconduct or a knowing violation of law; or

    - derived an improper personal benefit.

    ObjectSpace's Certificate of Incorporation requires ObjectSpace to indemnify
its directors, officers and employees and former directors, officers and
employees to the fullest extent permitted by the General Corporation Law of the
State of Delaware. Pursuant to the provisions of Section 145 of the General
Corporation Law of the State of Delaware, ObjectSpace has the power to indemnify
any person who was or is a party or is threatened to be made a party to any
threatened, pending, or completed action, suit or proceeding (other than an
action by or in the right of ObjectSpace) by reason of the fact that he is or
was a director, officer, employee or agent of ObjectSpace, against any and all
expenses, judgments, fines and amounts paid in settlement actually and
reasonably incurred in connection with such action, suit or proceeding. The
power to indemnify applies only if such person acted in good faith and in a
manner he reasonably believed to be in the best interest, or not opposed to the
best interest, of ObjectSpace, and with respect to any criminal action or
proceeding, had no reasonable cause to believe his conduct was unlawful.

    The power to indemnify applies to actions brought by or in the right of
ObjectSpace as well, but only to the extent of defense and settlement expenses
and not to any satisfaction of a judgment or

                                      II-1

settlement of the claim itself and with the further limitation that in such
actions no indemnification shall be made in the event of any adjudication of
negligence or misconduct unless the court, in its discretion, believes that in
light of all the circumstances indemnification should apply.

    The statute further specifically provides that the indemnification
authorized thereby shall not be deemed exclusive of any other rights to which
any such officer or director may be entitled under any bylaws, agreements, vote
of stockholders or disinterested directors, or otherwise.

    Reference is made to the Form of Underwriting Agreement, to be filed as
Exhibit 1.1 to this registration statement, which provides for indemnification
by the underwriters under certain circumstances of the directors and officers of
ObjectSpace signing the registration statement and certain controlling persons
of ObjectSpace against certain liabilities, including those arising under the
Securities Act.

    Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers or persons controlling ObjectSpace
pursuant to the foregoing provisions, ObjectSpace has been advised that in the
opinion of the Securities and Exchange Commission, such indemnification is
against public policy as expressed in the Securities Act and is therefore
unenforceable.

ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES

    During the past three years, the registrant has issued unregistered
securities to a limited number of persons as described below:

1.  On June 16, 1998, the registrant issued and sold a warrant to purchase up to
    196,000 shares of common stock at a purchase price of $0.01 per share in
    connection with a financing transaction.

2.  On September 4, 1998, the registrant issued and sold 571,429 shares of
    Series A preferred stock to one investor for $3.50 per share, or an
    aggregate of approximately $2.0 million.

3.  On December 30, 1998, the registrant issued and sold an aggregate of
    2,702,703 shares of Series B preferred stock to a total of 6 investors for
    $3.70 per share, or an aggregate of approximately $10.0 million.

4.  On December 30, 1998, the registrant issued and sold a warrant to purchase
    234,595 shares of common stock at a purchase price of $1.32 per share in
    connection with certain financing transactions.

5.  On December 23, 1999, in connection with one of our licensing and
    professional services transactions, the registrant issued a warrant to
    purchase that number of shares of common stock equal to $2.5 million divided
    by the offering price of the common stock in this offering.

6.  As of January 17, 2000, the registrant issued and sold a warrant to purchase
    up to 4,200 shares of common stock at a purchase price of $8.57 per share in
    connection with the registrant's obtaining services from a consultant.

7.  As of March 22, 2000, an aggregate of 322,977 shares of common stock had
    been issued upon exercise of options under the registrant's stock option
    plans.

    On January 14, 2000, the registrant effected a split of its common stock in
the form of a stock dividend of one share of common stock for each share of
common stock outstanding as of that date. On March 30, 2000, the registrant
effected a split of its common stock in the form of a stock dividend of 0.4
shares of common stock for each share of common stock outstanding as of that
date.

    None of the foregoing transactions involved any underwriters, underwriting
discounts or commissions, or any public offering, and the registrant believes
that each transaction was exempt from the registration requirements of the
Securities Act of 1933, as amended, by virtue of Section 4(2) thereof,
Regulation D promulgated thereunder or Rule 701 promulgated under Section 3(b)
thereof, pursuant to compensatory benefit plans and contracts relating to
compensation as provided under such Rule 701. The recipients in such
transactions represented their intention to acquire the securities for
investment only and not with a view to or for sale in connection with any
distribution thereof, and

                                      II-2

appropriate legends were affixed to the share certificates and instruments
issued in such transactions. All recipients had adequate access, through their
relationships with the registrant, to information about the registrant.

statements or notes thereto.

ITEM 17. UNDERTAKINGS

    The undersigned registrant hereby undertakes to provide to the underwriters
at the closing specified in the underwriting agreement, certificates in such
denominations and registered in such names as required by the underwriters to
permit prompt delivery to each purchaser.

    Insofar as indemnification by the registrant for liabilities arising under
the Securities Act of 1933 may be permitted to directors, officers and
controlling persons of the registrant pursuant to the provisions referenced in
Item 14 of this registration statement or otherwise, the registrant has been
advised that in the opinion of the Securities and Exchange Commission such
indemnification is against public policy as expressed in the Securities Act of
1933, and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
registrant of expenses incurred or paid by a director, officer, or controlling
person of the registrant in the successful defense of any action, suit or
proceeding) is asserted by a director, officer or controlling person in
connection with the securities being registered hereunder, the registrant will,
unless in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the
Securities Act of 1933 and will be governed by the final adjudication of such
issue.

    The undersigned registrant hereby undertakes that:

(1) For purposes of determining any liability under the Securities Act of 1933,
    the information omitted from the form of prospectus filed as part of this
    registration statement in reliance upon Rule 430A and contained in a form of
    prospectus filed by the registrant pursuant to Rule 424(b)(1) or
    (4) or 497(h) under the Securities Act of 1933 shall be deemed to be part of
    this registration statement as of the time it was declared effective.

(2) For the purpose of determining any liability under the Securities Act of
    1933, each post-effective amendment that contains a form of prospectus shall
    be deemed to be a new registration statement relating to the securities
    offered therein, and the offering of such securities at that time shall be
    deemed to be the initial bona fide offering thereof.

                                      II-4

                                   SIGNATURES

    Pursuant to the requirements of the Securities Act of 1933, the registrant
has duly caused this Registration Statement to be signed on its behalf by the
undersigned, thereunto duly authorized, in the city of Dallas, State of Texas,
on the 31st day of March, 2000.

                                                                        EXECUTIVE OFFICER


                               POWER OF ATTORNEY

cause to be filed the same, with all exhibits thereto, and other documents in
connection therewith, with the Securities and Exchange Commission granting unto
said attorneys-in-fact and agents the full power and authority to do and perform
each and every act and thing requisite and necessary to be done in and about the
foregoing, as to all intents and purposes as each of them might or could do in

agents or any of them, or their substitute or substitutes, may lawfully do or
cause to be done by virtue hereof.
