  This Prospectus contains forward-looking statements which involve risks and
uncertainties. The Company's actual results could differ materially from those
anticipated in these forward-looking statements as a result of certain factors,
including those set forth under "Risk Factors" and elsewhere in this
Prospectus. The following summary is qualified in its entirety by the more

and Notes thereto, appearing elsewhere in this Prospectus. Unless otherwise

                                  THE COMPANY
 
  TSI International Software Ltd. ("TSI Software" or the "Company") is a
leading provider of software and related services that enable organizations to
integrate their enterprise applications both internally and with external
business partners. The Company's flagship product, Mercator, is an applications
integration solution which permits enterprises to exchange information between
internal systems, to implement and integrate advanced client/server
applications such as SAP's R/3 enterprise resource planning ("ERP") system and
to integrate electronic data interchange ("EDI") data and Web-based
applications with their core business systems. In addition to Mercator, the
Company's Trading Partner products permit businesses to exchange information
with business partners and to integrate EDI data with back office applications.
 
  The evolution of enterprise computing has resulted in a proliferation of
business software applications across disparate and heterogeneous computing
systems. To improve effectiveness, efficiency and competitive positioning,
organizations are increasingly seeking to integrate and coordinate these
applications, both within the enterprise and with a growing number of external
business partners. The traditional approach to application integration -- in-
house custom development of interfaces -- is limited in its effectiveness and
is expensive, with integration costs for purchased business applications often
exceeding the cost of the applications themselves. The requirement for
integration, and the need for software tools which automate the integration
process, is increased with each new client/server, electronic commerce or Web-
based application added to the enterprise.
 
  The Company's products provide comprehensive off-the-shelf integration
solutions that can be quickly implemented and easily maintained and that
provide support for a broad range of applications, platforms, and data types.
Mercator for R/3 was the first product certified by SAP for use with its
Application Link Enabling ("ALE") architecture, an inter-application messaging
technology developed by SAP as a standard for interfacing with R/3. Mercator
for R/3 was also the first product certified for SAP's DMI (data migration
interface). Mercator addresses the need of SAP customers to integrate R/3 with
legacy and third-party applications in less time and at lower cost than
developing in-house custom interfaces. Similarly, for external applications,
the Company's Mercator and Trading Partner products permit customers to
integrate business processes across their supply and demand chains by
leveraging the Internet and other transport mechanisms for electronic commerce.
 
  The Company's strategy is to be the market leader in providing solutions that
integrate applications within the enterprise and between business partners.
Specifically, the Company seeks to extend its technology leadership in
application integration, particularly with respect to its Mercator product
line, and intends to target the market for enterprise application integration
with solutions for SAP R/3 and other enterprise applications markets. In
addition to these market and product strategies, the Company intends to expand
its existing channels of distribution, leverage its customer base by marketing
additional products and services to existing customers and to expand its
professional services capability to augment its software offerings.
 
  The Company markets its products and services through its direct sales force
and a network of value added resellers ("VARs"), independent software vendors
("ISVs"), systems integrators ("SIs") and distributors. The Company has
directly licensed its products to over 8,700 customers worldwide, representing
a broad range of industries. The Company's customers include Allegiance
Corporation, American Express Travel Related Services, Inc., Bell Atlantic,
CIGNA Corporation, Citibank, N.A., Federal Express Corporation, Hewlett-Packard
Company, Hoechst AG, IBM, Lucent Technologies, Inc., Prudential Insurance
Company of America and Texas Instruments.

                                 RISK FACTORS
 
  This Prospectus contains forward-looking statements which involve risks and
uncertainties. The Company's actual results could differ materially from those
anticipated in these forward-looking statements as a result of certain
factors, including those set forth in the following risk factors and elsewhere
in this Prospectus. In addition to the other information in this Prospectus,
the following risk factors should be considered carefully in evaluating the
Company and its business before purchasing the Common Stock offered by this
Prospectus.
 
POTENTIAL FLUCTUATIONS IN OPERATING RESULTS; SEASONALITY
 
  The Company's quarterly and annual operating results have varied
significantly in the past and are expected to do so in the future.
Accordingly, the Company believes that period to period comparisons of its
results of operations are not necessarily meaningful and should not be relied
upon as indications of future performance. The Company's revenues and results
of operations are difficult to forecast and could be adversely affected by
many factors, including, among others: the size, timing and terms of
individual license transactions; the sales cycle for the Company's products;
demand for and market acceptance of the Company's products and related
services (particularly its Mercator products); the number of businesses
implementing the SAP R/3 system and other ERP applications, as well as the
number of such businesses requiring third party enterprise application
integration software and related services; the Company's ability to expand,
and market acceptance of, its professional services business; the timing of
expenditures by the Company in anticipation of product releases or increased
revenue; the timing of product enhancements and product introductions by the
Company and its competitors; market acceptance of enhanced versions of the
Company's existing products and of new products; changes in pricing policies
of the Company and its competitors; variations in the mix of products and
services sold by the Company; the mix of channels through which products and
services are sold; the success of the Company in penetrating international
markets; the buying patterns and budgeting cycles of customers; personnel
changes, the Company's ability to attract and retain qualified sales,
professional services and research and development personnel and the rate at
which such personnel become productive; and general economic conditions. In
particular, the ability of the Company to achieve growth in the future will
depend on its success in adding a substantial number of sales, professional
services and research and development personnel. Competition for such
personnel is intense and there can be no assurance the Company will be able to
attract and retain these personnel.
 
  Licensing of the Company's software products historically has accounted for
a substantial portion of the Company's revenues, and the Company anticipates
that this trend will continue for the foreseeable future. Software license
revenues are difficult to forecast for a number of reasons. The Company
typically does not have a material backlog of unfilled orders, and revenues in
any quarter are substantially dependent on orders booked and shipped in that
quarter. The length of the sales cycles for the Company's products can vary
significantly from customer to customer and from product to product and, in
certain instances, can be as long as nine months or more. Furthermore, the
terms and conditions of individual license transactions, including prices and
discounts, may be negotiated based on volumes and commitments, and may vary
considerably from customer to customer. In addition, the Company has generally
recognized a substantial portion of its quarterly software licensing revenues
in the last month of each quarter. Accordingly, the cancellation or deferral
of even a small number of purchases of the Company's products has in the past
and could in the future have a material adverse effect on the Company's
business, operating results and financial condition.
 
  The Company's future revenues will also be difficult to predict and the
Company has, in the past, failed to achieve its revenue expectations for
certain periods. The Company's expense levels are based, in part, on its
expectation of future revenues, and expense levels are, to a large extent,
fixed in the short term. The Company may be unable to adjust spending in a
timely manner to compensate for any unexpected revenue shortfall. If revenue
levels are below expectations for any reason, operating results are likely to
be materially and adversely affected. Net income may be disproportionately
affected by a reduction in revenue because a large portion of the Company's
expenses is related to headcount that cannot be easily reduced without
 
                                       6

adversely affecting the Company's business. In addition, the Company currently
intends to increase its operating expenses by expanding its research and
product development staff, particularly research and development personnel to
be devoted to the Company's Mercator product line, increasing its sales and
marketing and professional services operations, expanding distribution
channels and hiring personnel in other operating areas. The Company expects to
experience a significant time lag between the date professional services,
sales and technical personnel are hired and the date such personnel become
fully productive. The timing of such expansion and the rate at which new
technical, professional services and sales personnel become productive as well
as the timing of the introduction and success of new distribution channels
could cause material fluctuations in quarterly results of operations.
Furthermore, to the extent such increased operating expenses precede or are
not subsequently followed by increased revenues, the Company's business,
operating results and financial condition could be materially and adversely
affected.
 
  Due to the foregoing factors, it is likely that in some future quarter the
Company's revenue or operating results will not meet the expectations of
public market analysts and investors. In such event, the price of the
Company's Common Stock would likely be materially and adversely affected.
 
  While the Company has not historically experienced any significant seasonal
fluctuations in its revenues or results of operations, it is not uncommon for
software companies to experience strong fourth quarters followed by weaker
first quarters, in some cases with sequential declines in revenues or
operating profit. The Company believes that many software companies exhibit
this pattern in their sales cycles primarily due to customers' buying patterns
and budget cycles. There can be no assurance that the Company will not display
this pattern in future years. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations."
 
DEPENDENCE ON MERCATOR PRODUCT LINE
 
  The Company introduced its Mercator products in 1993. In recent years, a
significant portion of the Company's revenue has been attributable to licenses
of its Mercator products and related services, and the Company expects that
revenue attributable to its Mercator products and related services will
represent an increasing portion of the Company's total revenue for the
foreseeable future. The development and marketing of its Mercator product line
has required the Company to, among other things, focus its attention and
resources away from some of its traditional products, market its products to a
different customer base and shift a large portion of its development efforts
to the Mercator product line. Accordingly, the Company's future operating
results are highly dependent on the market acceptance and growth of its
Mercator product line and enhancements thereto. There can be no assurance that
market acceptance of the Mercator product line will increase or remain at
current levels or that the Company will be able to successfully market the
Mercator product line and develop extensions and enhancements to this product
line on a long-term basis. In the event the Company's current or future
competitors release new products that provide, or are perceived as providing,
more advanced features, greater functionality, better performance, better
compatibility with other systems or lower prices than the Mercator product
line, demand for the Company's products and services would likely decline. See
"-- Risks Associated with Technological Change, Product Enhancements and New
Product Development" and "-- Competition." A decline in demand for, or market
acceptance of, the Mercator product line as a result of competition,
technological change or other factors would have a material adverse effect on
the Company's business, operating results and financial condition. See
"Business -- Products and Services."
 
DEPENDENCE ON SAP R/3 SYSTEM IMPLEMENTATIONS
 
  A substantial portion of the Company's sales of its Mercator products and
related services has been attributable to sales of Mercator for R/3 and
related services. The Company believes that its future revenue growth, if any,
will also depend in part upon continued sales of Mercator for R/3 and related
services. The Company has devoted and must continue to devote substantial
resources to identifying potential customers in the R/3 market, building
relationships with strategic partners and attracting and retaining skilled
technical,
 
                                       7
<PAGE>
 
sales and professional services personnel with expertise in R/3 systems.
Personnel with expertise in the R/3 system are in high demand and as such are
typically difficult to hire and retain. Regardless of the investments the
Company makes in pursuing this new market, there can be no assurance that the
Company will be successful in implementing a sales and marketing strategy
appropriate for this market or in attracting and retaining the necessary
skilled personnel.
 
  Demand for and market acceptance of Mercator for R/3 and related services
will be dependent on the continued market acceptance of the SAP R/3 system. As
a result, any factor adversely affecting demand for or use of SAP's R/3 system
could have a material adverse effect on the Company's business, operating
results and financial condition. Implementation of the SAP R/3 system is a
costly and time-consuming process and there can be no assurance that
businesses will choose to purchase such systems. Furthermore, there can be no
assurance that businesses which may implement such systems will wish to commit
the additional resources required to implement Mercator for R/3. In addition,
SAP could in the future introduce enterprise application integration solutions
competitive with Mercator for R/3 and related services. Moreover, any changes
in or new versions of SAP's R/3 system could materially and adversely affect
the Company's business, operating results and financial condition if the
Company were not able to successfully develop or implement any related changes
to Mercator for R/3 in a timely fashion. The Company will also be required to
maintain Mercator for R/3's certification for ALE, DMI and EDI. In order to
maintain such certifications, the Company's product must adhere to SAP's
technical specifications which are updated by SAP from time to time, and the
Company has no control over whether and when such specifications will be
changed. Any material change by SAP in such specifications could require the
Company to devote significant development resources to updating this product
to comply with such specifications. In such event, there can be no assurance
that the Company would be able to successfully modify Mercator for R/3 on a
timely basis, if at all, and any failure to do so could materially and
adversely affect the Company's business, operating results and financial
condition.
 
RISKS ASSOCIATED WITH TECHNOLOGICAL CHANGE, PRODUCT ENHANCEMENTS AND NEW
PRODUCT DEVELOPMENT
 
  The market for the Company's products and services is characterized by
extremely rapid technological change, frequent new product introductions and
enhancements, evolving industry standards, and rapidly changing customer
requirements. The introduction of products incorporating new technologies and
the emergence of new industry standards could render existing products
obsolete and unmarketable. Accordingly, the life cycles of the Company's
products are difficult to estimate. The Company's future success will depend
in part upon its ability to anticipate changes and enhance its current
products and develop and introduce new products that keep pace with
technological advancements and address the increasingly sophisticated needs of
its customers. The Company's products may be rendered obsolete if the Company
fails to anticipate or react to change. Development of enhancements to
existing products and new products depends, in part, on the timing of releases
of new versions of applications systems by vendors, the introduction of new
applications, systems or computing platforms, the timing of changes in
platforms, the release of new standards or changes to existing standards, and
changing customer requirements, among other factors. There can be no assurance
that the Company will be successful in developing and marketing product
enhancements or new products that respond to technological change, evolving
industry standards and changing customer requirements, that the Company will
not experience difficulties that could delay or prevent the successful
development, introduction and marketing of these products or product
enhancements, or that its product enhancements or new products will adequately
meet the requirements of the marketplace and achieve any significant degree of
market acceptance. The Company has in the past experienced delays in the
introduction of product enhancements and new products and may experience such
delays in the future. Furthermore, as the number of applications, systems and
platforms supported by the Company's products increases, the Company could
experience difficulties in developing on a timely basis product enhancements
which address the increased number of new versions of applications, systems or
platforms served by its existing products. Failure of the Company, for
technological or other reasons, to develop and introduce product enhancements
or new products in a timely and cost-effective manner or to anticipate and
respond adequately to changing market conditions, as well as
 
                                       8
<PAGE>
 
any significant delay in product development or introduction, could cause
customers to delay or decide against purchases of the Company's products,
which could have a material adverse effect on the Company's business,
operating results and financial condition.
 
  The Company may, in the future, seek to develop and market enhancements to
existing products or new products which are targeted for applications, systems
or platforms which the Company believes will achieve commercial acceptance.
These efforts could require the Company to devote significant development and
sales and marketing personnel as well as other resources to such efforts which
would otherwise be available for other purposes. There can be no assurance
that the Company will be able to successfully identify such applications,
systems or platforms, or that such applications, systems or platforms will
achieve commercial acceptance or that the Company will realize a sufficient
return on its investment. Failure of these targeted applications, systems or
platforms to achieve commercial acceptance or the failure of the Company to
achieve a sufficient return on its investment could have a material adverse
effect on the Company's business, operating results and financial condition.
 
  In addition, the introduction or announcement by the Company, or by one or
more of its current or future competitors, of products embodying new
technologies or features could render the Company's existing products obsolete
or unmarketable. There can be no assurance that the introduction or
announcement of enhanced or new product offerings by the Company or its
current or future competitors will not cause customers to defer or cancel
purchases of existing Company products. Such deferment or cancellation of
purchases could have a material adverse effect on the Company's business,
operating results and financial condition.
 
DEPENDENCE UPON DEVELOPMENT OF DISTRIBUTION CHANNELS
 
  The Company has recently expanded, and intends to continue to expand its
direct sales force. The Company's future success will depend in large part
upon the ability of the Company to attract, integrate, train, motivate and
retain new sales personnel. There can be no assurance that the Company's
efforts to expand its direct sales force to date or in the future will be
successful or that the cost of such efforts will not exceed the revenue
generated. In addition, the Company expects to experience a significant time
lag between the date sales personnel are hired and the date such personnel
become fully productive. The Company's inability to manage its sales force
expansion effectively could have a material adverse effect on the Company's
business, operating results and financial condition.
 
  An integral part of the Company's strategy is to also expand its indirect
sales channels such as VARs, ISVs, SIs and distributors. Although VARs, ISVs,
SIs and distributors have not accounted for a substantial percentage of the
Company's total revenues historically, the Company is increasing resources
dedicated to developing and expanding its indirect distribution channels.
There can be no assurance that the Company will be successful in expanding the
number of indirect distribution channels for its products. Furthermore, any
new VARs, ISVs, SIs or distributors may offer competing products, or have no
minimum purchase requirements of the Company's products. There can also be no
assurance that such third parties will provide adequate levels of services and
technical support. The inability of the Company to enter into additional
indirect distribution arrangements, the failure of such third parties to
perform under agreements with the Company and to penetrate their markets, or
the inability of the Company to retain and manage VARs, ISVs, SIs and
distributors with the technical and industry expertise required to market the
Company's products successfully could have a material adverse effect on the
Company's business, operating results and financial condition. There can be no
assurance that the Company's planned efforts to expand its use of VARs, ISVs,
SIs and distributors will be successful. To the extent that the Company is
successful in increasing its sales through indirect sales channels, it expects
that those sales will be at lower per unit prices than sales through direct
channels, and revenue to the Company for each such sale will be less than if
the Company had licensed the same product to the customer directly.
 
 
                                       9
<PAGE>
 
  Selling through indirect channels may limit the Company's contacts with its
customers. As a result, the Company's ability to accurately forecast sales,
evaluate customer satisfaction and recognize emerging customer requirements
may be hindered. The Company's strategy of marketing its products directly to
end-users and indirectly through VARs, ISVs, SIs and distributors may result
in distribution channel conflicts. The Company's direct sales efforts may
compete with those of its indirect channels and, to the extent different
resellers target the same customers, resellers may also come into conflict
with each other. Although the Company has attempted to manage its distribution
channels to avoid potential conflicts, there can be no assurance that channel
conflicts will not materially and adversely affect its relationships with
existing VARs, ISVs, SIs or distributors or adversely affect its ability to
attract new VARs, ISVs, SIs and distributors.
 
 
DEPENDENCE ON KEY PERSONNEL; NEED TO ATTRACT AND RETAIN SALES, PROFESSIONAL
SERVICES AND RESEARCH AND DEVELOPMENT PERSONNEL
 
  The Company's future success depends in large part on the continued service
of its key sales, professional services and research and development
personnel, as well as senior management. The loss of the services of any of
one or more of the Company's key employees could have a material adverse
effect on the Company's business, operating results and financial condition.
All employees are employed at-will and the Company has no fixed-term
employment agreements with its employees. The Company's future success also
depends on its ability to attract, train and retain highly qualified sales,
research and development, professional services and managerial personnel,
particularly sales, professional services and research and development
personnel with expertise in the SAP R/3 system. An increase in the Company's
sales staff is required to expand both the Company's direct and indirect sales
activities and to achieve revenue growth. Competition for such personnel is
intense, particularly for personnel with expertise in the SAP R/3 system, and
there can be no assurance that the Company can attract, assimilate or retain
such personnel. The Company has at times experienced and continues to
experience difficulty in recruiting qualified research and development and
sales personnel, and anticipates such difficulties in the future. The Company
has in the past experienced and in the future expects to continue to
experience a significant time lag between the date sales, professional
services and research and development personnel are hired and the date such
personnel become fully productive. If the Company is unable to hire and train
on a timely basis and subsequently retain such personnel in the future, the
Company's business, operating results and financial condition could be
materially and adversely affected.
 
MANAGEMENT OF GROWTH
 
  The Company's business has grown in recent periods, with total revenues
increasing from $16.1 million in 1995 to $26.7 million in 1997 and increasing
from $5.5 million for the first quarter of 1997 to $8.2 million for the
comparable period of 1998. The growth of the Company's business has placed,
and is expected to continue to place, a strain on the Company's
administrative, financial, sales and operational resources and increased
demands on its systems and controls. In particular, the Company noted an
increase in quarterly days sales outstanding from March 31, 1997 to March 31,
1998 from approximately 87 days to approximately 99 days, and an increase in
total accounts receivable from $5.3 million to $9.0 million. This increase in
quarterly days sales outstanding is the result of an increase in the amount of
sales occurring at the end of the quarter ended March 31, 1998 as compared
with the quarter ended March 31, 1997 and an extension of payment terms for
certain customers.
 
  To deal with these concerns, the Company has recently implemented or is in
the process of implementing and will be required to implement in the future a
variety of new and upgraded operational and financial systems, procedures and
controls and to hire additional administrative personnel. There can be no
assurance that the Company will be able to complete the implementation of and
to successfully integrate these systems, procedures and controls or hire such
personnel in a timely manner. The failure of the Company or its management to
respond to, and manage, its growth and changing business conditions, or to
adapt its operational, management and financial control systems to accommodate
its growth could have a material adverse effect on the Company's business,
operating results and financial condition. To promote growth in the Company's
sales and operations, the Company will also have to expand its sales and
marketing
 
                                      10
<PAGE>
 
organizations, expand and develop its distribution channels, fund increasing
levels of product development and increase the size of its training,
professional services and customer support organization to accommodate
expanded operations, and there can be no assurance that the Company will be
successful in these endeavors. See "Business -- Employees" and "Management."
 
DEPENDENCE ON THE INTERNET AND INTRANETS
 
  The Company believes that demand for enterprise application integration
solutions such as those offered by the Company will depend in part upon the
adoption by businesses and end-users of the Internet and intranets as a
platform for electronic commerce and communications both within and outside
the enterprise. The Internet and intranets are new and evolving, and there can
be no assurance of their widespread adoption, particularly for electronic
commerce and communications among businesses. Critical issues concerning the
Internet and intranets, including security, reliability, cost, ease of use and
access and quality of service, remain unresolved at this time, inhibiting
adoption by many enterprises and end-users. If the Internet and intranets are
not widely used by businesses and end-users, particularly for electronic
commerce, this could have an adverse effect on the Company's business,
operating results and financial condition.
 
COMPETITION
 
  The market for the Company's products and services is extremely competitive
and subject to rapid change. Because there are relatively low barriers to
entry in the software market, the Company expects additional competition from
other established and emerging companies. The Company believes that the
competitive factors affecting the market for the Company's products and
services include product functionality and features; quality of professional
services offerings; product quality, performance and price; ease of product
implementation; quality of customer support services; customer training and
documentation; and vendor and product reputation. The relative importance of
each of these factors depends upon the specific customer environment. Although
the Company believes that its products and services currently compete
favorably with respect to such factors, there can be no assurance that the
Company can maintain its competitive position against current and potential
competitors.
 
  In the enterprise application integration market, the Company's Mercator
products and related services compete primarily against solutions developed
internally by individual businesses to meet their specific enterprise
application integration needs. As a result, the Company must educate
prospective customers as to the advantages of the Company's products and
services as opposed to internally developed solutions and there can be no
assurance that the Company will be able to adequately educate potential
customers to the benefits provided by the Company's products and services. In
addition, the Company is facing increasing competition in the enterprise
application integration market from other third-party software vendors. In the
EDI market, the Company's Trading Partner products compete with products
offered by companies offering proprietary Value-Added Network ("VAN") services
as part of their EDI solution and the Company's PC-based Trading Partner
products also compete with PC-based products offered by a number of other EDI
software vendors.
 
  Many of the Company's current and potential competitors have longer
operating histories, significantly greater financial, technical, product
development and marketing resources, greater name recognition and larger
customer bases than the Company. The Company's present or future competitors
may be able to develop products comparable or superior to those offered by the
Company, adapt more quickly than the Company to new technologies, evolving
industry trends or customer requirements, or devote greater resources to the
development, promotion and sale of their products than the Company.
Accordingly, there can be no assurance that the Company will be able to
compete effectively in its markets, that competition will not intensify or
that future competition will not have a material adverse effect on the
Company's business, operating results and financial condition.
 
  The Company expects that it will face increasing pricing pressures from its
current competitors and new market entrants. The Company's competitors may
engage in pricing practices that reduce the average selling
 
                                      11
<PAGE>
 
prices of the Company's products and related services. To offset declining
average selling prices, the Company believes that it must successfully
introduce and sell enhancements to existing products and new products on a
timely basis and develop enhancements to existing products and new products
that incorporate features that can be sold at higher average selling prices.
To the extent that enhancements to existing products and new products are not
developed in a timely manner, do not achieve customer acceptance or do not
generate higher average selling prices, the Company's operating margins may
decline, and such decline could have a material adverse effect on the
Company's business, operating results and financial condition. See
"Business --  Competition."
 
DEPENDENCE ON PROPRIETARY TECHNOLOGY
 
  The Company's success is dependent upon its proprietary software technology.
The Company does not currently have any patents and relies principally on
trade secret, copyright and trademark laws, nondisclosure and other
contractual agreements and technical measures to protect its technology. The
Company also believes that factors such as the technological and creative
skills of its personnel, product enhancements and new product developments are
essential to establishing and maintaining a technology leadership position.
The Company enters into confidentiality and/or license agreements with its
employees, distributors and customers, and limits access to and distribution
of its software, documentation and other proprietary information. There can be
no assurance that the steps taken by the Company will prevent misappropriation
of its technology, and such protections do not preclude competitors from
developing products with functionality or features similar to the Company's
products. Furthermore, there can be no assurance that third parties will not
independently develop competing technologies that are substantially equivalent
or superior to the Company's technologies. In addition, effective copyright
and trade secret protection may be unavailable or limited in certain foreign
countries. Any failure by or inability of the Company to protect its
proprietary technology could have a material adverse effect on the Company's
business, operating results and financial condition.
 
  Although the Company does not believe its products infringe the proprietary
rights of any third parties, there can be no assurance that infringement
claims will not be asserted against the Company or its customers in the
future. Furthermore, the Company may initiate claims or litigation against
third parties for infringement of the Company's proprietary rights or to
establish the validity of the Company's proprietary rights. Litigation, either
as plaintiff or defendant, would cause the Company to incur substantial costs
and divert management resources from productive tasks whether or not such
litigation is resolved in the Company's favor, which could have a material
adverse effect on the Company's business, operating results and financial
condition. Parties making claims against the Company could secure substantial
damages, as well as injunctive or other equitable relief which could
effectively block the Company's ability to license its products in the United
States or abroad. Such a judgment could have a material adverse effect on the
Company's business, operating results and financial condition. If it appears
necessary or desirable, the Company may seek licenses to intellectual property
that it is allegedly infringing. There can be no assurance, however, that
licenses could be obtained on commercially reasonable terms, if at all, or
that the terms of any offered licensed will be acceptable to the Company. The
failure to obtain the necessary licenses or other rights could have a material
adverse effect on the Company's business, operating results and financial
condition. As the number of software products in the industry increases and
the functionality of these products further overlaps, the Company believes
that software developers may become increasingly subject to infringement
claims. Any such claims, with or without merit, can be time consuming and
expensive to defend and could adversely affect the Company's business,
operating results and financial condition. There are currently no pending
claims that the Company's products, trademarks or other proprietary rights
infringe upon the proprietary rights of third parties. See "Business --
Proprietary Technology."
 
RISKS ASSOCIATED WITH INTERNATIONAL EXPANSION
 
  Although international revenues accounted for only 9.4% and 6.8% of the
Company's total revenues for 1997 and the three months ended March 31, 1998,
respectively, the Company intends to expand its sales and marketing resources
outside of the United States, which will require significant management
 
                                      12
<PAGE>
 
attention and financial resources. The Company also expects to commit
additional time and development resources to customizing its products for
selected international markets and to developing international sales and
support channels. None of the Company's products is currently a "double byte"
product, which is required to localize these products in certain non-English
character set markets such as Asia. The Company is currently developing double
byte versions of its Mercator products and believes that in the future it will
be required to engage in other localization activities. There can be no
assurance that such efforts will be successful.
 
  International operations involve a number of additional risks, including the
impact of possible recessionary environments in economies outside the United
States, longer receivables collection periods and greater difficulty in
accounts receivable collection, unexpected changes in regulatory requirements,
dependence on independent resellers, reduced protection for intellectual
property rights in some countries, tariffs and other trade barriers, foreign
currency exchange rate fluctuations, difficulties in staffing and managing
foreign operations, the burdens of complying with a variety of foreign laws,
potentially adverse tax consequences and political and economic instability.
To the extent the Company's international operations expand, the Company
expects that an increasing portion of its international license and service
and other revenues will be denominated in foreign currencies, subjecting the
Company to fluctuations in foreign currency exchange rates. The Company does
not currently engage in foreign currency hedging transactions. However, as the
Company continues to expand its international operations, exposures to gains
and losses on foreign currency transactions may increase. The Company may
choose to limit such exposure by the purchase of forward foreign exchange
contracts or similar hedging strategies. There can be no assurance that any
currency exchange strategy would be successful in avoiding exchange-related
losses. There can be no assurance that the foregoing factors will not have a
material adverse effect on the Company's future international revenue and,
consequently, on the Company's business, operating results and financial
condition. The Company believes that its growth will require expansion of its
sales in foreign markets and expects to rely principally on resellers in those
markets, rather than substantially increase its direct sales force to serve
those markets. There can be no assurance that the Company will be able to
sustain or increase revenue derived from international sources.
 
RISK OF SOFTWARE DEFECTS; PRODUCT LIABILITY
 
  Software products as complex as those offered by the Company may contain
defects or failures when introduced or when new versions are released. The
Company has in the past discovered software defects in certain of its products
and may experience delays or lost revenue to correct such defects in the
future. There can be no assurance that, despite testing by the Company, errors
will not be found in new products or releases after commencement of commercial
shipments, resulting in loss of market share or failure to achieve market
acceptance. Any such occurrence could have a material adverse effect upon the
Company's business, operating results and financial condition.
 
  The Company's license agreements with its customers typically contain
provisions designed to limit the Company's exposure to potential product
liability claims. It is possible, however, that the limitation of liability
provisions contained in the Company's license agreements, especially unsigned
"shrink-wrap" licenses, may not be effective under the laws of certain
jurisdictions. Consequently, the sale and support of the Company's software
entails the risk of such claims in the future. The Company currently has a
standard business owner's insurance policy but does not have insurance
specifically for software product liability risks or software errors and
omissions. Any product liability claim brought against the Company could have
a material adverse effect upon the Company's business, operating results and
financial condition.
 
POTENTIAL ACQUISITIONS
 
  If appropriate opportunities present themselves, the Company intends to
acquire businesses, products or technologies that the Company believes are
strategic, although the Company currently has no understandings, commitments
or agreements with respect to any material acquisition and no material
acquisition is currently
 
                                      13
<PAGE>
 
being pursued. There can be no assurance that the Company will be able to
identify, negotiate or finance such acquisitions successfully, or to integrate
such acquisitions with its current business. The process of integrating an
acquired business, product or technology into the Company may result in
unforeseen operating difficulties and expenditures and may absorb significant
management attention that would otherwise be available for ongoing development
of the Company's business. Moreover, there can be no assurance that the
anticipated benefits of any acquisition will be realized. Acquisitions could
result in potentially dilutive issuances of equity securities, the incurrence
of debt, contingent liabilities and/or amortization expenses related to
goodwill and other intangible assets, which could materially adversely affect
the Company's business, operating results and financial condition. Any such
future acquisitions of other technologies, products or companies may require
the Company to obtain additional equity or debt financing, which may not be
available or may be dilutive.
 
YEAR 2000 IMPLICATIONS
 
  Many currently installed computer systems and software products are unable
to distinguish 21st century dates from 20th century dates. Beginning in the
year 2000, these date code fields will need to distinguish 21st century dates
from 20th century dates, and, as a result, many companies' software and
computer systems may need to be upgraded or replaced in order to comply with
such "Year 2000" requirements. The Company has on occasion warranted, and
generally represents to its customers, that its products are free from Year
2000 defects. There can be no assurance that the Company's products are Year
2000 compliant, or that the Company's products will not be integrated with, or
otherwise interact with, non-compliant software. The foregoing could expose
the Company to claims from its customers and result in the loss of or delay in
market acceptance of the Company's products, increased service and warranty
costs to the Company and payment by the Company of compensatory or other
damages, any of which events could have a material adverse effect on the
Company's business, operating results and financial condition. Although the
Company believes that its internal systems are Year 2000 compliant, the
failure of any third-party systems to operate properly with regard to the Year
2000 and thereafter could have a material adverse effect on the Company's
business, results of operations and financial condition. Furthermore, the
purchasing patterns of potential customers may be affected by Year 2000 issues
as companies expend significant resources to correct their current systems for
Year 2000 compliance.
 
POSSIBLE VOLATILITY OF STOCK PRICE
 
  The market price of the Common Stock has risen substantially since the
Company's initial public offering. The trading price of the Common Stock has
fluctuated in the past and may be significantly affected by factors such as
actual or anticipated fluctuations in the Company's operating results,
announcements of technological innovations or new products by the Company or
its competitors, developments with respect to patents, copyrights or
proprietary rights, conditions and trends in the software or other industries,
general market conditions and other factors. In addition, the stock market has
from time to time experienced significant price and volume fluctuations that
have particularly affected the market prices for the common stocks of
technology companies. These broad market fluctuations may adversely affect the
market price of the Company's Common Stock. In the past, following periods of
volatility in the market price of a company's securities, securities class
action litigation has often resulted. There can be no assurance that such
litigation will not occur in the future with respect to the Company. Such
litigation could result in substantial costs and a diversion of management's
attention and resources, which could have a material adverse effect upon the
Company's business, operating results and financial condition.
 
FACTORS INHIBITING TAKEOVER
 
  The Company's Certificate of Incorporation includes a provision that allows
the Board of Directors to issue up to 5,000,000 shares of Preferred Stock and
to determine the price, rights, preferences, privileges, and restrictions,
including voting rights, of those shares without any further vote or action by
the stockholders. Preferred Stock could be issued, without stockholder
approval, that could have voting, liquidation and
 
                                      14
<PAGE>
 
dividend rights superior to that of existing stockholders. The issuance of
Preferred Stock could adversely affect the voting powers of holders of Common
Stock and the likelihood that such holders would receive dividend payments and
payments on liquidation. The Company has no current plans to issue any
Preferred Stock. In addition, Section 203 of the Delaware General Corporation
Law ("Section 203") restricts certain business combinations with any
"interested stockholder" as defined by such statute. The issuance of Preferred
Stock as well as the provisions of Section 203 could also make it more
difficult for a third party to acquire control of the outstanding voting stock
of the Company and thereby have the effect of delaying or preventing a change
in control of the Company. See "Description of Capital Stock--Delaware Anti-
Takeover Law."
 
UNCERTAINTY AS TO USE OF PROCEEDS
 
  The Company has no specific plans as to the use of substantially all of the
net proceeds from this offering, other than for general working capital
purposes. Accordingly, the Company's management will retain broad discretion
to allocate the net proceeds from this offering to uses that the stockholders
may not deem desirable and there can be no assurance that the proceeds can or
will yield a significant return. See "Use of Proceeds."
 
SHARES ELIGIBLE FOR FUTURE SALE
 
  Upon completion of this offering, there will be 10,742,873 shares of Common
Stock of the Company outstanding (based on shares outstanding as of April 30,
1998), of which 8,265,838 shares will be eligible for immediate sale in the
public market without restriction. Taking into account certain shares subject
to lock-up agreements and notwithstanding possible earlier eligibility for
sale under the provisions of Rules 144 and 144(k), the number of shares that
will be available for sale in the public market will be as follows:
(i) approximately 252,930 shares will be eligible for immediate sale on the
effective date, (ii) 150,000 shares are eligible for sale subject to certain
volume and other resale restrictions under Rule 144, (iii) approximately
2,074,105 shares will become eligible for sale 90 days after the effective
date upon the expiration of certain lock-up agreements, subject to certain
volume and other resale restrictions pursuant to Rule 144. The Company has
registered 3,616,671 shares of the Company's Common Stock reserved for
issuance upon exercise of outstanding options or for future grants or
purchases under its stock option plans and stock purchase plan.
 
  In addition, upon completion of this offering, there will remain outstanding
Warrants to purchase 269,490 shares of Common Stock at an exercise price of
$2.00 per share. These Warrants are exercisable at any time on a net exercise
basis. Accordingly, any shares of Common Stock issuable upon such net exercise
would be available for resale in the public market, subject to public
information, volume limitation or notice provisions of Rule 144, in the case
of affiliates.
 
  Following this offering, the holders of 1,736,259 shares of the Company's
Common Stock and holders of Warrants to purchase 269,490 shares of Common
Stock will have certain rights to register those shares of Common Stock under
the Securities Act. See "Description of Capital Stock" and "Shares Eligible
for Future Sale."

                                USE OF PROCEEDS
 
  The net proceeds to the Company from the sale of the 1,200,000 shares of
Common Stock offered by the Company hereby at a public offering price of
$19.00 per share are estimated to be approximately $21.2 million after
deducting underwriting discounts and commissions and estimated offering
expenses. In addition, the Company will receive $764,562 upon exercise of the
Selling Stockholder Warrant. The Company will not receive any proceeds from
the sale of Common Stock by the Selling Stockholders.
 
  The Company has no current specific plans for the net proceeds of this
offering, but the Company expects to use such net proceeds for general
corporate purposes, including working capital. A portion of the proceeds may
also be used to acquire or invest in complementary businesses or products or
to obtain the right to use complementary technologies. The Company presently
has no commitments or understandings for any material acquisitions or
investments, and is not presently engaged in any discussions or negotiations
for any such acquisitions or investments. Pending use of the net proceeds for
the above purposes, the Company intends to invest such funds in short-term,
interest-bearing, investment-grade obligations.

                                DIVIDEND POLICY
 
  The Company has never declared or paid any cash dividends on its Common
Stock. The Company currently anticipates that it will retain all future
earnings for use in its business and does not anticipate paying any cash
dividends on its Common Stock in the foreseeable future. The payment of any
future dividends will be at the discretion of the Company's Board of Directors
and will depend upon, among other things, future earnings, operations, capital
requirements, the general financial condition of the Company, general business
conditions and contractual restrictions on payment of dividends, if any. The
Company's credit agreement with its bank prohibits the payment of dividends
without the bank's written consent.

                     MANAGEMENT'S DISCUSSION AND ANALYSIS 
               OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
  The following Management's Discussion and Analysis of Financial Condition
and Results of Operations contains forward-looking statements which involve
risks and uncertainties. The Company's actual results could differ materially
from those anticipated in these forward-looking statements as a result of
certain factors, including those set forth under "Risk Factors" and elsewhere
in this Prospectus. The following discussion should be read in conjunction
with the Financial Statements and Notes thereto included elsewhere in this
Prospectus.
 
OVERVIEW
 
  The Company was incorporated in Connecticut in 1985 and reincorporated in
Delaware in September 1993. In June 1991, the Company began developing its
Mercator product and in December 1993 released Version 1.0 of Mercator. The
Company released the latest version of Mercator in August 1997 and released
its Mercator for R/3 product in June 1996.
 
  Historically, the Company has derived a majority of its revenues from
products other than Mercator, primarily its Trading Partner family of products
and its KEY/MASTER product. However, revenue related to Mercator has grown
significantly in each of the last four years and has increased as a percentage
of total revenues. The Company believes that future growth in revenues, if
any, will be mainly attributable to its Mercator product line. In view of the
relatively recent introduction of Mercator, the Company believes it cannot
accurately predict the amount of revenues that will be attributable to such
products or the life of such products. To the extent the Company's Mercator
products do not achieve market acceptance, the Company's business, operating
results and financial condition will be materially and adversely affected.
 
  The Company's revenues are derived principally from two sources: (i) license
fees for the use of the Company's software products and (ii) service fees for
maintenance, consulting services and training related to the Company's
software products. The Company generally recognizes revenue from software
license fees upon shipment, unless the Company has significant post-delivery
obligations, in which case revenues are recognized when such obligations are
satisfied. The Company's mainframe EDI product licenses typically include one
year of annual maintenance, the fee for which typically represents
approximately 15% of the total amount paid by the customer for the product.
The Company's KEY/MASTER product is licensed under term-use contracts rather
than for a one-time license fee, and the Company recognizes revenue from such
arrangements on a present-value basis at the inception of the contract.
Revenues from consulting and training are recognized as services are
performed, and maintenance revenues are recognized ratably over the
maintenance period, typically one year. The Company does not actively market
new term-use contracts for KEY/MASTER but continues to receive KEY/MASTER
revenues, principally maintenance revenues. As a result, KEY/MASTER accounts
for a larger proportion of maintenance revenue than license revenues and
increases the percentage of the Company's total revenues represented by
services, maintenance and other revenues. The Company intends to increase the
scope of its service offerings insofar as it supports the sale of its
products. The Company believes that software licensing will continue to
account for a larger portion of its total revenues than service, maintenance
and other revenues.
 
  Mercator can be used by IT professionals as well as VARs, ISVs, SIs or other
third parties who resell, embed or otherwise bundle Mercator with their
products. To date, license fee revenues have been derived principally from
direct sales of software products through the Company's direct sales force.
Although the Company believes that such direct sales will continue to account
for a significant portion of software licensing revenues, the Company intends
to increase its use of distributors and resellers. Furthermore, the Company's
planned expansion of its sales organization is expected to cause sales and
marketing expenses to increase.
 
  The Company markets its products in North America primarily through its
direct sales and telesales organizations. Throughout the rest of the world,
the Company markets its products through distributors,
 
                                      19

resellers and direct sales. International revenue accounted for 10.4%, 9.4%
and 6.8% of total revenues for 1996, 1997 and the three months ended March 31,
1998, respectively. The Company maintains an international sales and support
office in the United Kingdom. The Company intends to increase its
international direct sales force and focus on establishing additional
international distributor and reseller relationships, such as its recent
distribution agreement with Mitsui. See "Risk Factors -- Risks Associated with
International Expansion."
 
  The size of the Company's orders can range from a few thousand dollars to
over $100,000 per order. The loss or delay of large individual orders,
therefore, can have a significant impact on the revenues and other quarterly
results of the Company. In addition, the Company has generally recognized a
substantial portion of its quarterly software licensing revenues in the last
month of each quarter, and as a result, revenue for any particular quarter may
be difficult to predict. Because the Company's operating expenses are
relatively fixed, a delay in the recognition of revenue from a limited number
of license transactions could cause significant variations in operating
results from quarter to quarter and could result in significant losses. To the
extent such expenses precede, or are not subsequently followed by, increased
revenue, the Company's operating results would be materially and adversely
affected. As a result of these and other factors, operating results for any
quarter are subject to variation, and the Company believes that period-to-
period comparisons of its results of operations are not necessarily meaningful
and should not be relied upon as indications of future performance.
 
  At December 31, 1997, the Company had federal tax net operating loss
carryforwards of $6,849,000 expiring between the years 2000 and 2009 and
research and experimentation credits of $655,900 expiring between 2003 and
2008. Section 382 of the Internal Revenue Code imposes a limitation on the
amount of tax loss carryforwards which can be utilized in any year after there
has been a 50% or greater ownership change of the Company. The ownership
change is based on the number of shares of stock or the aggregate market value
of the stock within any consecutive three year period. Future years'
utilization of the Company's tax loss carryforwards will be subject to this
limitation as a result of this offering, however the Company does not
currently anticipate that this limitation will have a material adverse effect
on the Company's ability to utilize these loss carryforwards.
 
  In accordance with Statement of Financial Accounting Standards No. 86,
Accounting for the Costs of Computer Software to be Sold, Leased or Otherwise
Marketed, software development costs are expensed as incurred until
technological feasibility has been established, at which time such costs are
capitalized until the product is available for general release to customers.
To date, the establishment of technological feasibility of the Company's
products and general release of such software have substantially coincided. As
a result, software development costs qualifying for capitalization have been
insignificant, and therefore, the Company has not capitalized any software
development costs.

THREE MONTHS ENDED MARCH 31, 1998 COMPARED WITH THREE MONTHS ENDED MARCH 31,
1997
 
 Revenues
 
  Total Revenues. The Company's total revenues increased 49% from $5.5 million
in the first three months of 1997 to $8.2 million in the comparable period of
1998.
 
  Software Licensing. Software licensing revenues increased 91% from $2.7
million in the first three months of 1997 to $5.2 million in the comparable
period of 1998, primarily as a result of a substantial increase in Mercator
license revenues.
 
  Service, Maintenance and Other. Service, maintenance and other revenues
increased 7% from $2.8 million in the first three months of 1997 to $3.0
million in the comparable period of 1998, primarily as a result of an increase
in professional services revenues primarily associated with sales of Mercator
and, to a lesser extent, an increase in Mercator maintenance revenue,
partially offset by a slight decrease in KEY/MASTER maintenance revenues.
Maintenance revenues attributable to KEY/MASTER were $1.1 million and $1.0
million for the first three months of 1997 and 1998, respectively.
 
 Cost of Revenues
 
  Cost of software licensing revenues consists primarily of media, manuals,
distribution costs and the cost of third party software that the Company
resells. Cost of service, maintenance and other revenues consists primarily of
personnel-related costs in providing maintenance, technical support,
consulting and training to
 
                                      21
<PAGE>
 
customers. Gross margin on software licensing revenues is higher than gross
margin on service, maintenance and other revenues, reflecting the low
materials, packaging and other costs of software products compared with the
relatively high personnel costs associated with providing maintenance,
technical support, consulting and training services. Cost of service,
maintenance and other revenues also varies based upon the mix of maintenance,
technical support, consulting and training services.
 
  Cost of Software Licensing. Cost of software licensing revenues increased
37% from $174,000 in the first three months of 1997 to $239,000 in the
comparable period of 1998, primarily due to increased sales of software
licenses. Software licensing gross margin remained relatively constant at 94%
and 95% in the first three months of 1997 and 1998, respectively.
 
  Cost of Service, Maintenance and Other. Cost of service, maintenance and
other revenues increased 38% from $548,000 in the first three months of 1997
to $755,000 in the comparable period of 1998, primarily due to increased
professional services personnel. Service, maintenance and other gross margin
decreased from 80% to 75% in the first three months of 1997 and 1998,
respectively.
 
 Operating Expenses
 
  Product Development. Product development expenses include expenses
associated with the development of new products and enhancements to existing
products and consist primarily of salaries, recruiting and other personnel-
related expenses, depreciation of development equipment, supplies, travel and
allocated facilities and communications costs. Product development expenses
increased 14% from $1.1 million in the first three months of 1997 to $1.2
million in the comparable period of 1998, primarily due to increased product
development activities relating to the Company's Mercator product line.
Product development expenses as a percentage of total revenue decreased from
20% of total revenues in the first three months of 1997 as compared to 15% of
total revenues in the comparable period of 1998. The Company believes that a
significant level of research and development expenditures is required to
remain competitive. Accordingly, the Company anticipates that it will continue
to devote substantial resources to research and development. The Company
expects that the dollar amount of research and development expenses will
increase through at least the remainder of 1998. To date, all research and
development expenditures have been expensed as incurred.
 
  Selling and Marketing. Selling and marketing expenses consist of sales and
marketing personnel costs, including sales commissions, recruiting, travel,
advertising, public relations, seminars, trade shows, product descriptive
literature and allocated facilities and communications costs. Selling and
marketing expenses increased 58% from $2.6 million in the first three months
of 1997 to $4.1 million in the comparable period of 1998, primarily due to the
increased number of sales and marketing personnel to focus on the Mercator
product line and increased expenditures for Mercator-related marketing
programs. Selling and marketing expenses as a percentage of total revenues
increased from 47% of total revenues in the first three months of 1997 as
compared to 50% of total revenues in the comparable period of 1998. The
Company expects to continue hiring additional sales and marketing personnel
and to increase promotional expenses through at least the remainder of 1998 to
focus on the Mercator product line and anticipates that sales and marketing
expenses will increase in absolute dollar amount.
 
  General and Administrative. General and administrative expenses consist
primarily of salaries, recruiting and other personnel-related expenses for the
Company's administrative, executive and finance personnel as well as outside
legal and audit costs. General and administrative expenses increased 58% from
$777,000 in the first three months of 1997 to $1.2 million in the comparable
period of 1998, primarily due to increased administrative expenses associated
with new systems to support the Company's growth and as a result of additional
costs related to being a public company. General and administrative expenses
as a percentage of total revenue increased from 14% of total revenues in the
first three months of 1997 to 15% of total revenues for the comparable period
of 1998. The Company believes that the dollar amount of its general and
administrative expenses will increase as the Company expands its
administrative staff to support the Company's growth.

 Other Income (Expense), Net
 
  Interest income represents income earned on the Company's cash balances as
well as on its term-use contracts. Interest income increased from $(32,000) in
the first three months of 1997 to $323,000 in the comparable period of 1998,
due to higher cash balances resulting from the Company's initial public
offering. The Company had minimal borrowing expenses in the three months ended
March 31, 1998 as compared to $63,000 for the three months ended March 31,
1997.
 
 Provision for Income Taxes
 
  The Company recorded provision for income taxes of $7,000 and $105,000 in
the three months ended March 31, 1997 and 1998, respectively, reflecting a
higher effective tax rate estimated for 1998.
 
YEAR ENDED DECEMBER 31, 1997 COMPARED WITH YEAR ENDED DECEMBER 31, 1996
 
 Revenues
 
  Total Revenues. Total revenues increased 40% from $19.0 million in 1996 to
$26.7 million in 1997.
 
  Software Licensing. Software licensing revenues increased 57% from $9.3
million in 1996 to $14.6 million in 1997, primarily due to a 97% increase in
Mercator license revenues, partially offset by a decrease in licenses of the
Company's mainframe-based Trading Partner and KEY/MASTER products.
 
  Service, Maintenance and Other. Service, maintenance and other revenues
increased 25% from $9.7 million in 1996 to $12.1 million in 1997, primarily
due to a 125% increase in professional services revenues, particularly
professional services associated with Mercator and, to a lesser extent, an
increase in Mercator maintenance revenue, offset by a slight decrease in
maintenance revenue related to the Company's mainframe-based Trading Partner
and KEY/MASTER products. Maintenance revenues attributable to KEY/MASTER were
$4.6 million and $4.2 million for 1996 and 1997, respectively.
 
 Cost of Revenues
 
  Cost of Software Licensing. Cost of software licensing revenues increased
57% from $495,000 in 1996 to $778,000 in 1997. This increase was due to an
increase in product sales of Mercator. Software licensing gross margin
remained constant at 95% in 1996 and 1997.
 
  Cost of Service, Maintenance and Other. Cost of service, maintenance and
other revenues increased 25% from $2.0 million in 1996 to $2.5 million in
1997. The increase was primarily due to an increase in the number of support
personnel related to the Company's Mercator product. Service, maintenance and
other gross margin remained constant at 79% in 1996 and 1997.
 
 Operating Expenses
 
  Product Development. Product development expenses increased 29% from $3.5
million in 1996 to $4.5 million in 1997, primarily due to increased headcount
associated with the development of new Mercator-based products. Product
development expenses represented 18% and 17% of total revenues for 1996 and
1997, respectively.
 
  Selling and Marketing. Selling and marketing expenses increased 50% from
$8.7 million in 1996 to $13.1 million in 1997. This increase was primarily due
to the increased number of sales and marketing personnel required to focus on
the Mercator product line and increased spending on Mercator-related marketing
programs. Selling and marketing expenses represented 47% and 50% of total
revenues for 1996 and 1997, respectively.
 
                                      23
<PAGE>
 
  General and Administrative. General and administrative expenses increased
31% from $2.9 million in 1996 to $3.8 million in 1997. The increase was
primarily due to increased management and management information system staff
and increased depreciation expenses for computer equipment and system
upgrades. General and administrative expenses represented 15% and 14% of total
revenues for 1996 and 1997, respectively.
 
 Other Income (Expense), Net
 
  Interest income increased from $135,000 in 1996 to $688,000 in 1997 due to
investment income earned on proceeds from the Company's initial public
offering. Borrowing expenses decreased from $286,000 in 1996 to $186,000 in
1997 due to the repayment of the Company's bank debt with the proceeds of the
Company's initial public offering.
 
 Provision for Income Taxes
 
  The Company recorded provision for income taxes of $36,000 and $76,000 in
1996 and 1997, respectively. Due to the utilization of net operating loss
carryforwards the provision for income taxes for 1996 and 1997 were not
significant.
 
YEAR ENDED DECEMBER 31, 1996 COMPARED WITH YEAR ENDED DECEMBER 31, 1995
 
 Revenues
 
  Total Revenues. Total revenues increased 18% from $16.1 million in 1995 to
$19.0 million in 1996.
 
  Software Licensing. Software licensing revenues increased 23% from $7.6
million in 1995 to $9.3 million in 1996, primarily due to a 74% increase in
Mercator license revenues, partially offset by a decrease in licenses of the
Company's mainframe-based Trading Partner and KEY/MASTER products.
 
  Service, Maintenance and Other. Service, maintenance and other revenues
increased 14% from $8.5 million in 1995 to $9.7 million in 1996, primarily due
to a 53% increase in professional services revenues, particularly professional
services associated with Mercator and, to a lesser extent, an increase in
Mercator maintenance revenue, offset by a slight decrease in maintenance
revenue related to the Company's mainframe-based Trading Partner and
KEY/MASTER products. Maintenance revenues attributable to KEY/MASTER were $4.9
million and $4.6 million for 1995 and 1996, respectively.
 
 Cost of Revenues
 
  Cost of Software Licensing. Cost of software licensing revenues decreased
32% from $725,000 in 1995 to $495,000 in 1996, primarily due to termination of
amortization relating to the Company's acquisition of Foretell Corp. Software
licensing gross margin increased from 90% in 1995 to 95% in 1996, primarily
due to termination of such amortization.
 
  Cost of Service, Maintenance and Other. Cost of service, maintenance and
other revenues decreased 9% from $2.2 million in 1995 to $2.0 million in 1996.
The decrease was primarily due to a decrease in the number of support
personnel related to the Company's mainframe-based Trading Partner and
KEY/MASTER products. Service, maintenance and other gross margin increased
from 74% in 1995 to 79% in 1996, primarily due to the decrease in such support
personnel.
 
 Operating Expenses
 
  Product Development. Product development expenses increased 13% from $3.1
million in 1995 to $3.5 million in 1996, primarily due to increased headcount
associated with the development of Mercator. Product development expenses
represented 19% and 18% of total revenues for 1995 and 1996, respectively.
 
  Selling and Marketing. Selling and marketing expenses increased 22% from
$7.2 million in 1995 to $8.7 million in 1996. This increase was primarily due
to the increased number of sales and marketing personnel required to focus on
the Mercator product line and increased spending on Mercator-related marketing
programs. Selling and marketing expenses represented 44% and 46% of total
revenues for 1995 and 1996, respectively.
 
                                      24
<PAGE>
 
  General and Administrative. General and administrative expenses increased
46% from $2.0 million in 1995 to $2.9 million in 1996. The increase was
primarily due to increased management and MIS staff, increased provision for
bad debts and increased depreciation. General and administrative expenses
represented 13% and 15% of total revenues for 1995 and 1996, respectively.
 
 Other Income (Expense), Net
 
  Other income decreased from $370,000 in 1995 to $135,000 in 1996 due to a
one-time benefit in 1995 of $177,000 from the settlement of a lawsuit in the
Company's favor and a decrease in the amount of interest earned on term
license contracts. Borrowing expenses decreased from $420,000 in 1995 to
$286,000 in 1996 due to reduced borrowing levels.
 
 Provision for Income Taxes
 
  The Company recorded provision for income taxes of $34,000 and $36,000 in
1995 and 1996, respectively. Due to the utilization of net operating loss
carryforwards, the provisions for income taxes for 1995 and 1996 were not
significant.

SELECTED QUARTERLY RESULTS OF OPERATIONS
 
  The following tables set forth certain unaudited quarterly statement of
operations data for each of the nine quarters in the period ended March 31,
1998, as well as such data expressed as a percentage of the Company's total
revenues for the periods indicated. This data has been derived from unaudited
financial statements that have been prepared on the same basis as the audited
financial statements and, in the opinion of management, include all
adjustments, consisting of normal recurring adjustments, necessary for a fair
presentation of the information. The Company's quarterly results have in the
past been and may in the future be subject to significant fluctuations. As a
result, the Company believes that results of operations for interim periods
should not be relied upon as any indication of the results to be expected in
any future period. See "Risk Factors -- Potential Fluctuations in Operating
Results; Seasonality."

  The Company's revenues and operating expenses increased sequentially in each
quarter of 1996, 1997 and the first quarter of 1998, except that software
licensing revenues decreased in the first quarter of 1997 and service,
maintenance and other revenue decreased in the first quarter of 1998. The
Company believes the decrease in software licensing revenues was primarily due
to the buying patterns and budgeting cycles of its customers. The increases in
revenues and operating expenses during 1996 were primarily attributable to the
increase in Mercator-related revenues as well as Mercator-related product
development and sales and marketing expenses. While the Company has not
historically experienced any significant seasonal fluctuations in its revenues
or results of operations, it is not uncommon for software companies to
experience strong fourth quarters followed by weaker first quarters, in some
cases with sequential declines in revenues or operating profit. The Company
believes that many software companies exhibit this pattern in their sales
cycles primarily due to customers' buying patterns and budget cycles. There
can be no assurance that the Company will not display this pattern in future
years.
 
  The Company's quarterly operating results have varied significantly in the
past and are expected to do so in the future. Accordingly, the Company
believes that period to period comparisons of its results of operations are
not necessarily meaningful and should not be relied upon as indications of
future performance. The Company's revenues and results of operations are
difficult to forecast and could be adversely affected by many factors,
including, among others: the size, timing and terms of individual license
transactions; the sales cycle for the Company's products; demand for and
market acceptance of the Company's products and related services, particularly
its Mercator products; the number of businesses implementing the SAP R/3
system and other ERP applications, as well as the number of such businesses
requiring third party enterprise application integration software and related
services; the Company's ability to expand, and market acceptance of, its
professional services business; the timing of expenditures by the Company in
anticipation of product releases or increased revenues; the timing of product
enhancements and product introductions by the Company and its competitors;
market acceptance of enhanced versions of the Company's existing products and
of new products; changes in pricing policies of the Company and its
competitors; variations in the mix of products and services sold by the
Company; the mix of channels through which products and services are sold; the
success of the Company in penetrating international markets; the buying
patterns and budgeting cycles of customers; personnel changes, difficulty in
attracting and retaining qualified sales, professional services and research
and development personnel and the rate at which such personnel become
productive; and general economic conditions. In particular, the ability of the
Company to achieve growth in the future will depend on its success in adding a
substantial number of sales, professional services and research and
development personnel. Competition for such personnel is intense and there can
be no assurance the Company will be able to attract and retain these
personnel.

LIQUIDITY AND CAPITAL RESOURCES
 
  In July 1997, the Company sold 3,000,000 shares of its Common Stock in its
initial public offering. The total net proceeds to the Company from the
initial public offering were $24.3 million, $3.4 million of which were used to
repay indebtedness under the Company's bank line of credit. Prior to its
initial public offering, the Company funded its operations through private
sales of equity securities, its bank line of credit and cash from operations.
At March 31, 1998, the Company had net working capital of $24.8 million, which
included cash and marketable securities of $22.4 million.
 
  Operating activities provided (used) net cash of $1.3 million, $730,000,
$(196,000) and $890,000 during 1995, 1996, 1997 and the three months ended
March 31, 1998, respectively. The Company generated net cash in 1995 and 1996
primarily as a result of its improved profitability during these periods. The
cash used in 1997 is due to increased accounts receivable and to the increase
in the proportion of sales billed during the last month of 1997 as compared to
1996. The cash used in the three months ended March 31, 1998 was due to
increased accounts receivable.
 
  Investing activities (used) net cash of $(354,000), $(828,000) and $(11.4
million) during 1995, 1996, and 1997, respectively, primarily to fund capital
expenditures needed to support expansion of the Company's business in 1995 and
1996 and, in 1997, primarily related to purchases of short-term securities.
Investing activities provided cash of $1.8 million during the three months
ended March 31, 1998 due primarily to the sale of marketable securities during
the quarter.
 
  Financing activities provided (used) net cash of $(1.3 million), $(102,000),
$22.4 million and $554,000, for 1995, 1996, 1997 and the three months ended
March 31, 1998, respectively, from repayments of debt in 1995 and 1996 and net
proceeds received from the Company's initial public offering in 1997,
partially offset in 1997 by repayments of debt.
 
  The Company has a line of credit facility with the Bank of New York which
provides for borrowings equal to the lesser of $4.0 million or 80% of the sum
of eligible accounts receivable and certain other receivables contracts.
Borrowings may take the form of prime rate loans (which bear interest at the
bank's prime rate plus 1.0%) or LIBOR rate loans (which bear interest at the
applicable LIBOR rate plus 3.0%). The Company's obligations under this credit
line are secured by substantially all of the Company's assets. The bank line
of credit contains certain financial covenants and also prohibits cash
dividends, mergers and acquisitions. The Company had no borrowings outstanding
as of March 31, 1998 and does not anticipate any borrowings in the foreseeable
future.
 
  Net accounts receivable were $9.0 million at March 31, 1998 compared to $5.3
million at March 31, 1997. The number of days of average revenues in accounts
receivables was 99 at March 31, 1998 compared to 87 at March 31, 1997. This
increase in quarterly days sales outstanding is the result of an increase in
the amount of sales occurring at the end of the quarter ended March 31, 1998
as compared with the quarter ended March 31, 1997 and an extension of payment
terms for certain customers. Capital expenditures have been, and future
capital expenditures are anticipated to be, primarily for facilities,
equipment and computer software to support expansion of the Company's
operations. As of March 31, 1998, the Company had no material commitments for
capital expenditures. The Company's bank line of credit generally limits
capital expenditures to $400,000 per quarter. As of December 31, 1997, the
Company had $44,000 of capital lease obligations and commitments under
operating lease agreements totalling $6.0 million through 2011, including $1.2
million for 1998. See Note 11 of Notes to Financial Statements.
 
  The Company believes that the net proceeds from this offering, together with
its current cash and cash equivalent balances and any net cash generated by
operations, will be sufficient to meet its anticipated cash needs for working
capital, capital expenditures and business expansion for at least the next 12
months. Thereafter, if cash generated by operations is insufficient to satisfy
the Company's operating requirements, the Company may seek additional debt or
equity financing. There can be no assurance that such financing will be
available on terms acceptable to the Company. The sale of additional equity or
debt securities could result in dilution to the Company's stockholders. A
portion of the Company's cash could also be used to
 
                                      28
<PAGE>
 
acquire or invest in complementary businesses or products or otherwise to
obtain the right to use complementary technologies. From time to time, in the
ordinary course of business, the Company evaluates potential acquisitions of
such businesses, products or technologies. The Company has no present
understandings, commitments or agreements with respect to any material
acquisitions of other businesses, products or technologies.
 
YEAR 2000 COMPLIANCE
 
  Many currently installed computer systems and software products are unable
to distinguish 21st century dates from 20th century dates. Beginning in the
year 2000, these date code fields will need to distinguish 21st century dates
from 20th century dates. The Company has completed an assessment of the "Year
2000" issue with respect to its computer systems. The Company has replaced or
upgraded its internal systems within the past 18 months and the Company
believes they are Year 2000 compliant. The Company is also in the process of
communicating with its suppliers and customers to determine the extent to
which it may be affected by any third party's Year 2000 issues. The Company
also believes that all of its products are Year 2000 compliant. Therefore, the
Company believes that the Year 2000 will not have a material adverse effect on
the Company's business, operating results and financial condition. See "Risk
Factors--Year 2000 Issues."
 
RECENT ACCOUNTING PRONOUNCEMENTS
 
  In June 1997, Statement of Financial Accounting Standard ("SFAS") No. 131,
"Disclosures about Segments of an Enterprise and Related Information," was
issued. SFAS No. 131 establishes standards for the way that public business
enterprises report information about operating segments in annual financial
statements and requires that those enterprises report selected information
about operating segments in interim financial reports issued to shareholders
which is currently not required. It also establishes standards for related
disclosures about products and services, geographic areas, and major
customers. The Company is required to adopt this standard as of December 31,
1998.
 
  In June 1997, Statement of Financial Accounting Standard ("SFAS") No. 130
"Reporting Comprehensive Income," was issued. SFAS No. 130 establishes
standards for reporting and disclosure of comprehensive income and its
components in a full set of general-purpose financial statements. This
statement requires that all items that are required to be recognized under
accounting standards as components of comprehensive income be reported. Other
comprehensive income for the three months ended March 31, 1998 was $44,700 and
is comprised of the change in the foreign currency translation.
 
  In October 1997 the AICPA issued SOP 97-2, "Software Revenue Recognition,"
which supersedes SOP 91-1. SOP 97 -2 generally requires revenue earned on
software arrangements involving multiple elements, such as additional software
products, upgrades or enhancements, rights to exchange or return software,
postcontract customer support, or services, including elements deliverable
only on a when-and-if-available basis, to be allocated to the various elements
of such sale based on "vendor-specific objective evidence of fair values"
allocable to each such element.
 
  The Company adopted SOP 97-2 for software transactions entered into
beginning January 1, 1998. Such adoption did not have a material effect on the
timing of the Company's revenue recognition and the Company believes that it
will not have a material impact on its results of operations for the year
ended December 31, 1998.

INDUSTRY BACKGROUND
 
  As enterprise computing has evolved, corporations have deployed systems and
software in an effort to improve business processes, reduce costs and increase
organizational effectiveness. Organizations are now faced with a proliferation
of software applications and an increasingly heterogeneous and disparate
computing environment across the enterprise. At the same time, organizations
are increasingly seeking to integrate their various business processes and the
applications that support them through such initiatives as enterprise resource
planning systems ("ERP"), supply chain management projects and Web-based
electronic commerce. For many organizations, these factors have made it
increasingly critical yet substantially more difficult to provide application-
to-application interoperability and to share information within and beyond the
enterprise.
 
  The number of applications deployed throughout the enterprise has increased
dramatically, now including both enterprise-wide systems such as SAP's R/3 and
function-specific applications such as sales force automation or customer
support. In addition to purchasing applications from independent software
vendors, most organizations continue to run customized, internally developed
solutions for specific applications. The proliferation of both internally
developed and third party applications has both increased the need to
integrate applications and has greatly complicated the integration process.
 
  As the number of applications has increased, the number and variety of the
computing platforms and systems on which they run has also grown
significantly. The evolution of computing from mainframes to client/server and
then to the Internet and corporate intranets has not led to the emergence of a
single preferred platform, but rather has resulted in a coexistence among new
and legacy architectures. The number of technology architectures being
supported is, in fact, increasing. According to a 1996 study by Sentry Market
Research, a typical large organization has an average of 10 different
operating systems and 8 different Database Management Systems ("DBMSs") as
compared with 4 different operating systems and 3 different DBMSs in 1991.
This diversity compounds the difficulty faced by organizations in providing
application-to-application integration.
 
  In addition to these technological trends within the enterprise, the number
of externally linked business partners is increasing. Many corporations,
seeking to improve their market responsiveness, competitive position and
internal efficiency are creating extended "virtual" organizations among
suppliers and customers using electronic commerce technology. Electronic
commerce, which combines standards for exchanging data such as EDI with low-
cost methods for data transport such as the Internet, now accounts for a wide
variety of business transactions including, among others, electronic payments,
purchase orders, invoices, health claims and mortgage applications. The
proliferation of partners, each with its own internal systems and
applications, and the increased demand for creating electronic information
flows across both the supply and demand chains, have exacerbated the
difficulty in integrating applications between business partners.
 
                                      30

  Historical approaches to integrating applications have been expensive,
difficult to implement and maintain, and limited in their effectiveness. For
example, the costs of integrating R/3 with existing systems often equals or
exceeds the cost of the R/3 application software itself. Similarly, the cost
of integrating EDI with an organization's business applications often can be
the largest single cost component of implementing EDI solutions.
Traditionally, organizations have approached the integration problem on a
case-specific basis, writing individual programs to allow applications to
share information for a specific task or use. Such custom coding is time
consuming, prone to error, inflexible and difficult to maintain over time. In
addition, an individual solution coded for one specific application generally
cannot be used for other integration needs. As the number of potential
interfaces grows with each new application, the inability to leverage these
home-grown solutions becomes increasingly problematic. Although some software
tools are available to assist developers with the integration task, most are
"point" solutions designed for specific platforms, applications, DBMSs or data
formats and typically require custom coding to create complete solutions.
 
  As a result, organizations require a new approach to integrating business
applications, both within the enterprise and with external business partners.
A comprehensive, off-the-shelf solution is needed that can be rapidly
implemented and easily maintained, does not require custom interface programs,
and supports a heterogenous mix of platforms, architectures, databases and
third-party applications.
 
TSI SOFTWARE'S SOLUTION
 
  TSI Software develops and markets software products and related services
that allow organizations to facilitate the integration of information between
enterprise applications as well as with external business partners. Key
benefits of the TSI Software enterprise application integration solution
include:
 
  Comprehensive Internal and External Solution. TSI Software delivers
comprehensive solutions for integrating enterprise applications both within
the enterprise and between business partners. Mercator achieves this by
transforming the business data from any application so that it can be used by
other applications without modifying the applications, without regard to the
number of applications involved, and despite differing data structures, syntax
or business rules. In addition, Mercator is scaleable to support mission-
critical enterprise integration requirements. The Company's EDI solutions
permit its customers to exchange information with business partners and to
integrate EDI data with back office applications. The Company provides
external integration solutions which leverage the Internet as a transport
mechanism for EDI and allow enterprises to integrate Web-based applications
and transactions with existing enterprise systems.
 
  Broad Application, Platform and Data Type Support. To satisfy the wide-
ranging needs of large organizations, TSI Software's solutions provide
comprehensive application, platform and data type support. Mercator can be
used to integrate internally developed as well as third party systems
regardless of the vendor of an application, the tools or programming language
in which the application is written or the standards on which the application
is based. Mercator links applications running on a wide variety of operating
systems running on popular PC, Windows NT and UNIX systems, such as HP, Sun
Solaris and RS/6000, as well as IBM mainframes and Digital, AS/400 and Stratus
hardware. Mercator transforms data in any format, including user defined
formats, proprietary formats, such as IDocs (SAP R/3 data definitions) and
DXOB (SAP R/3 initial data conversion) and industry standard formats such as
HL7 (healthcare standard for clinical information) and S.W.I.F.T.
(international banking transactions), and the Company's EDI solutions support
the full range of EDI standards, both national and international.
 
  Pre-Packaged R/3 Solution. The Company's Mercator for R/3 product is an off-
the-shelf solution enabling customers of SAP's R/3 to more easily integrate
R/3 modules with legacy and third-party applications. Mercator for R/3 was the
first product to be certified by SAP for use with ALE and DMI and is also
certified for SAP's EDI interface. Mercator for R/3 extends the Company's core
Mercator product by providing functionality to automatically capture R/3 data
definitions and adapters for integrating with R/3's inter-application
messaging system. Mercator for R/3 allows enterprises to preserve the value of
legacy data, utilize best-of-breed software applications and reduce the cost
of implementing R/3 in distributed computing environments.

  Ease of Implementation. The Company's Mercator and Trading Partner products
are off-the-shelf products which install easily and are designed to provide a
rapid return on investment. With Mercator, information technology ("IT")
professionals use a graphical user environment to create complete data
transformation solutions without the need to write custom interfaces or tailor
individual modules of code. Mercator provides a set of pre-built "plug-ins,"
including adapters for specific applications, transactions, DBMSs, and
messaging systems, in order to simplify development of enterprise application
integration solutions. The Company's EDI products enable users to be
"commerce-ready" with little or no customization required.
 
STRATEGY
 
  The Company's strategy is to be the leading supplier of software solutions
and related services for integrating enterprise applications within the
enterprise and between business partners. Key elements of the Company's
strategy include:
 
  Leverage and Extend Technology Leadership. The Company intends to continue
to extend its leading enterprise application integration products, such as
those for SAP's R/3 System. The Company continually seeks to leverage its core
Mercator technology by developing pre-packaged solutions for additional
enterprise applications, data formats, DBMSs, messaging systems and computing
platforms. For example, the Company recently introduced Mercator for EC, an
enterprise-wide client/server application for distributed electronic commerce.
The Company is the leading provider of Windows-based EDI software and has
developed Trading Partner PC/32, the first desktop EDI product designed for
Windows 95 and Windows NT.
 
  Target the Enterprise Application Market. The Company believes that
significant opportunity exists for software solutions which enable enterprise
wide ERP systems to be integrated with other applications throughout the
organization. The Company currently markets Mercator for R/3 for users of
SAP's R/3 and intends to develop and market additional pre-packaged versions
of Mercator with functionality targeted specifically at other popular
enterprise application suites.
 
  Expand Distribution Channels. In addition to expanding its direct sales
force, the Company is focusing its sales and marketing efforts on third-party
vendors of application software, connectivity tools, systems integration
services and other products and services which complement the Company's core
capabilities. The Company believes that such relationships can provide market
visibility for the Company's products, additional sales opportunities, and an
additional source of services and technical support for the Company's
customers. The Company intends to expand these third-party channels in both
domestic and international markets. For example, in January 1998, the Company
entered into a Pan-Asian distribution agreement with Mitsui & Co. Ltd.
 
  Leverage Customer Base. The Company intends to market its products and
services in order to expand their use within existing customer accounts. The
Company believes significant opportunity exists to increase the number of
Mercator licenses sold to its existing customers as ERP systems continue to be
rolled out within their organizations. In addition, the Company believes that
its customers are increasingly pursuing emerging applications such as Web-
based electronic commerce and data warehousing initiatives and that this
provides an opportunity to use Mercator to integrate these new applications
with existing enterprise systems.
 
  Expand Professional Services Capability. As the Company's solutions have
become more central to mission critical applications, there has been an
increased demand for comprehensive service offerings to complement the
Company's products. The Company intends to increase the number of its service
professionals and the scope of its service offerings with the goal of
maximizing license revenues from sales of its products. The Company intends to
augment its own service offerings by seeking strategic relationships with
major systems integrators and other service providers. For example, to promote
Mercator for R/3, the Company has developed education programs which are
marketed directly by SAP and offered by the Company's personnel at SAP
training centers.

 Mercator Products
 
  The Company's flagship Mercator family of products is used by IT
professionals to integrate data between different enterprise applications.
Mercator was initially released in December 1993 and, as of March 31, 1998,
had been licensed to more than 1,300 customers worldwide.
 
  Mercator. Mercator enables application integration by transforming or
mapping data between and among multiple data formats of business applications.
It provides a Windows-based Authoring System which is used to define data
formats and mapping solutions, and separate run-time Server Engines for map
execution. Complete data transformations can be created without writing custom
interface programs. Mercator requires no pre-processing of data prior to
mapping, can transform data between multiple sources and destinations in a
single process, and supports map execution on a wide range of platforms.
Customers who deploy a map to run on multiple platforms also license a Server
Engine for each platform. The Company currently offers Server Engines for
Windows 3.1, Windows 95, Windows NT, PC DOS, SCO UNIX, HP-UX, Sun Solaris/OS,
AIX, Alpha NT, Digital UNIX, VAX VMS, Open VMS, OS/400, Stratus FTX, VOS and
Continuum, MVS, and MVS/CICS. Mercator is complementary with most of the major
tools and protocols for messaging and data transport. Resource adapters are
provided for IBM MQSeries, Microsoft MQ, and TIBCO Rendezvous, as well as the
major tools for database access including DB2, Oracle, SQL Server, Sybase and
the databases supported by ODBC. In addition, the Company has recently
developed a resource adapter for Oracle AQ.
 
  Mercator for R/3. Initially released in June 1996, Mercator for R/3 is a
version of Mercator that includes specific extensions to meet the needs of
integration of data with SAP's R/3 system. Mercator for R/3 was the first
software product to be certified by SAP for use with ALE and DMI. Mercator for
R/3 has also been certified for the SAP EDI interface. This makes TSI Software
the first company to be certified by SAP for all
 
                                      33
<PAGE>
 
three R/3 interfaces (ALE, EDI and DMI). Mercator for R/3 extends the core
Mercator product by providing functionality to automatically capture R/3 data
definitions, and adapters for integrating with R/3's inter-application
messaging system. In addition, Mercator for R/3 provides data transformation
support for other R/3 data conversion and interfacing requirements including
the initial conversion of data to R/3 from existing systems and interfaces
with data warehouses.
 
  Mercator for EC. Mercator for EC, which is currently in controlled release,
is an enterprise-wide client/server solution for distributed electronic
commerce based on the Windows NT platform. It supports distributed management
and maintenance of the EC environment as well as distributed processing of EC
transactions. With Mercator for EC, numerous business units within an
enterprise can be supported and each business unit can create its own
customizable job streams for transaction processing. Transaction workflows can
be tailored to match the processing requirements of each area of the business.
Mercator for EC extends Mercator to electronic commerce by providing a
flexible, open architecture for creating robust, event-driven electronic
commerce solutions.
 
 Trading Partner Products
 
  The Company's Trading Partner products consist of a set of EDI management
software products and include Trading Partner PC, a Windows-based product, and
Trading Partner EC, a mainframe-based product. The Trading Partner products
can be sold as stand-alone EDI products, but are often sold in conjunction
with Mercator products to enable businesses to both manage their EDI
relationships and to integrate their EDI data into enterprise applications.
Trading Partner products allow customers to communicate with their partners
through direct connections, VANs or the Internet.
 
  Trading Partner PC. Introduced in 1990, Trading Partner PC was the first
Windows-based EDI translator in the United States and has been licensed to
more than 5,000 businesses worldwide. In October 1996, the Company introduced
Trading Partner PC/32, the first Windows 95 desktop solution in the market.
The Company has developed more than 100 "kits" which support a particular
trading partner's EDI specifications and provide "plug and play" solutions for
EDI trading. The Company markets kits for many major EDI trading partners
including General Motors, Ford Motor Company, J.C. Penney Company, Inc.,
Sears, Roebuck and Company, Target Stores and Wal-Mart Stores, Inc. The
Company also provides comprehensive EDI rollout programs for large
corporations such as Compaq, Hewlett-Packard, IBM, Kohler Company and Kaiser
Permanente. The Company's OnCall*EDI products are a series of EDI kits for
electronic purchasing for the health care provider market and as of March 31,
1998 had been licensed to more than 1,300 hospitals.
 
  Trading Partner EC. Trading Partner EC is a mainframe-based EDI translation
product which provides EDI management capability for companies with large EDI
programs. It includes Mercator as its core data transformation engine and
offers the user the means to integrate EDI data directly into applications
without the need to write custom interface programs commonly required by other
translator products. Using Mercator, customers who plan to migrate their EDI
program from the mainframe can do so without incurring additional cost and
effort for recreating their EDI interfaces. As of March 31, 1998, Trading
Partner EC and its predecessor product have been licensed to more than 200
businesses worldwide.
 
 KEY/MASTER
 
  In addition to the Company's enterprise application integration products
described above, the Company licenses and supports KEY/MASTER, a legacy data
entry product which is used on mainframe terminals or PCs on local area
networks, and is the leading software product for automating the key entry of
high volume, repetitive data from business documents. KEY/MASTER has been
licensed to more than 900 customers worldwide. Because KEY/MASTER is a mature
product, revenues derived from KEY/MASTER are primarily maintenance-related
and the Company expects in the future to make only minor investments in
KEY/MASTER.

 Services
 
  Professional Services. The Company offers consulting and professional
services to customers who wish to have the Company's professionals plan,
design or implement their enterprise application integration projects. The
Company intends to expand the number of service professionals and the scope of
the services offered as it continues to address the enterprise application
integration needs of large organizations. The Company believes that
enterprises implementing the R/3 system in particular represent a significant
opportunity for the Company to market its professional services in support of
Mercator for R/3.
 
  Training. In order to assure that its customers are successful in using its
products, the Company provides training in its four training centers or at
customer locations. The Company offers a number of courses ranging from two to
five days in length with educational content including basic product
functionality and hands-on use of the product. The Company recommends that its
Mercator customers attend a basic three-day training course and believes that
a majority of its Mercator customers elect to participate in such training. In
order to promote Mercator for R/3, the Company has developed education
programs which are marketed directly by SAP and offered by the Company's
personnel at SAP training centers.
 
CUSTOMERS
 
  As of March 31, 1998, the Company had directly licensed its software to more
than 8,700 customers worldwide. Numerous others have licensed the Company's
products through VARs, ISVs, SIs or other third parties who distribute its
products to business partners to facilitate the integration of their
respective business applications.
 
  The Company's customer base includes businesses from many industries,
including finance, banking, healthcare, technology, government, retail,

SALES AND MARKETING
 
 Sales
 
  The Company markets its products and services through both direct and third
party channels. The Company's goal is to achieve broad market penetration by
pursuing multiple channels of distribution.
 
  As of March 31, 1998, the Company's sales organization consisted of 59
employees. The Company's direct field sales force focuses on sales of Mercator
and Trading Partner products to Fortune 1000 companies. The Company also
maintains a telesales organization as part of its direct sales force which
generally targets smaller businesses. The field sales force also includes
alternate channel managers who are responsible for sales through third
parties. The sales organization includes systems engineers who assist with
both pre- and post-sales activities.
 
  An important part of the Company's sales strategy is to continue to develop
its indirect distribution channels such as VARs, ISVs, SIs and distributors.
As of March 31, 1998, over 100 third parties had agreements with the Company
to resell, embed or otherwise bundle the Company's products with their
offerings in the United States. In February 1998, the Company announced a Pan-
Asian distribution agreement with Mitsui. Under the terms of the agreement,
Mitsui can distribute Mercator for integration of ERP software, such as SAP
R/3 and electronic commerce, worldwide and can appoint resellers in various
Asian countries, including Japan, China, Indonesia and Taiwan. See "Risk
Factors -- Dependence Upon Development of Distribution Channels."
 
  The Company markets its products and services outside of North America
through sales offices located in the United Kingdom and France as well as
through indirect channels. Revenues from international customers were 9.4% and
6.8% of the Company's total revenues during 1997 and the three months ended
March 31, 1998, respectively. The international market is important to the
Company, and it intends to continue to expand its sales and marketing efforts
outside North America by adding distributors and additional sales staff. See
"Risk Factors -- Risks Associated with International Expansion."
 
 Marketing
 
  The Company utilizes a wide variety of marketing programs which are intended
to attract potential customers and to promote the Company and its brand names.
The Company uses a mix of market research, analyst updates, seminars, direct
mail, print advertising, tradeshows, speaking engagements, public relations,
customer newsletters, and Web site marketing in order to achieve these goals.
The marketing department also produces collateral material for distribution to
prospects including demonstrations, presentation materials, white papers,
brochures, fact sheets, and materials that are specific to the area of
interest. The Company also hosts an annual user conference for its customers
and provides an Alliance Program to support its channel partners with a
variety of programs, incentives, support plans and an annual conference. As of
March 31, 1998, there were 10 employees in the Company's marketing
organization.
 
TECHNOLOGY
 
  The Company's core Mercator technology provides a platform for creating data
transformation solutions which satisfy application integration requirements
across a variety of computing environments. The architecture of the Mercator
platform is based on object concepts, providing reusability, interoperability
and scaleability during the design process and in the resulting solutions. The
Mercator platform permits the Company to efficiently construct and deliver
integration solutions for specific markets and also allows ISVs and SIs to
embed Mercator functionality within their own offerings.
 
  The central components of the Mercator platform are a Windows-based
Authoring System for creating data transformation "maps" and one or more run-
time Server Engines for map execution. A map is an executable module that
describes the required transformation and re-ordering of data between source
and
 
                                      36
<PAGE>
 
destination objects such as files, databases, applications and messages. The
Authoring System provides an intuitive drag-and-drop environment for defining
the source and destination data objects, defining the rules for mapping the
sources to the destinations, and building the resulting map object. Map
objects built using Mercator can be ported automatically to any of 21
different execution environments. Graphical Transaction Workflow facilities
are also available for defining and managing entire systems of maps, including
the ability to trigger map executions based on time, events, commands or
through an API.
 
 
               [FLOWCHART OF THE MERCATOR PLATFORM APPEARS HERE]

In the upper left corner of the chart is the heading "Data Objects" which 
includes the following subheadings: R/3; X12 EDI; EDIFACT; S.W.I.F.T; HL7; and 
COBOL. In the lower left corner of the chart is the heading "Resource Adapters" 
which includes the following subheadings: Databases; Messaging systems; 
Transaction monitors; File transfer software; Mail systems; and Value added 
networks (VANs). In the lower right corner of the chart is the heading 
"Execution Triggers" which includes the following subheadings: Messaging; Files;
Databases; Time; Commands; and APIs.

  To simplify data definition, the Company provides pre-packaged objects for a
number of commonly used data standards. The Company also provides importers
for creating objects from higher level (meta) data definitions. Descriptions
of source and destination objects can also be entered by the user through
Mercator's graphical interface. Data object definitions within Mercator
include information regarding their format, structure and business rules,
which eliminates the need to explicitly identify the context of a data object
during map construction and maintains the logical integrity of the resulting
mapping solution.
 
  Once the source and destination objects are available, the user creates maps
by specifying the rules for transforming data from the sources to the
destinations. For many mapping tasks, the user need only "drag" a source
object and "drop" it on the destination object. Multiple data sources can be
transformed to multiple destinations in a single mapping operation. The user
has point-and-click access to a variety of pre-built functions to enhance the
mapping rules including support for selection, extraction, computation,
logical operations, parsing, substitution, re-ordering, validation and
conversion.
 
  Using Mercator's Authoring System, map objects are built and tested in the
Windows environment. The resulting Mercator map can be implemented using a
Mercator Server Engine appropriate to the target platform. Target platforms
currently supported include Windows 3.1, Windows 95, Windows NT, PC DOS, SCO
UNIX, open server, Sun Solaris/OS, IBM AIX, Digital Alpha NT, Alpha UNIX, VAX
VMS, Open VMS, OS/400, OS/390 Stratus FTX and VOS, MVS and MVS/CICS.
 
  The Company provides adapters and importers which interface to and from
specific databases, messaging systems, and applications enabling connectivity
to a specific source or destination that can be defined directly within a
mapping operation. Mercator is complementary with most of the major tools and
protocols for
 
                                      37
<PAGE>
 
messaging and data transport. Resource adapters are provided for IBM MQSeries,
Microsoft MQ, and TIBCO Rendezvous, as well as the major tools for database
access including DB2, Oracle, SQL Server, Sybase and the databases supported
by ODBC. In addition, the Company has recently developed a resource adapter
for Oracle AQ. In addition, the Company provides pre-packaged data objects for
national and international standards for EDI, S.W.I.F.T. and data definitions
for specific industries such as healthcare and transportation.
 
  Mercator was architected so that adapters and importers can be added without
modifying the core Mercator technology. Mercator for R/3, for example, is a
packaged offering which leverages the core Mercator Authoring System and
Server Engines by providing adapters for communicating with SAP ALE
architecture and importers for SAP R/3 IDocs and DXOB. The Company's other
products also leverage Mercator's core technology. The underlying EDI
translation support for OnCall*EDI is provided by Mercator and Trading Partner
EC incorporates Mercator as the data integration component for integrating EDI
data with existing applications. In addition, the Company's customers can use
Mercator to create their own applications where embedded data transformation
is a requirement.
 
PRODUCT DEVELOPMENT
 
  Since inception, the Company has made substantial investments in research
and development through both internal development and technology acquisition.
The Company expects that most of its enhancements to existing products and new
products will be developed internally. However, the Company will evaluate on
an ongoing basis externally developed technologies for integration into its
product lines.
 
  The Company expects that a substantial majority of its research and
development activities will be related to developing enhancements and
extensions to its Mercator and Trading Partner product lines. Following
Mercator's introduction, product development was initially driven by demand
for additional mapping functionality and support for additional execution
platforms. Later, development focus shifted to automating Mercator support for
specific sources and destinations through an expanded set of adapters and
importers, and development of additional pre-packaged integration solutions
for specific markets. During the second half of 1997, the Company added
graphical transaction workflow management functionality to the core set of
Mercator capabilities. During the first quarter of 1998, the Company developed
messaging system adapters for Microsoft MQ, TIBCO Rendezvous and Oracle AQ and
added database connectivity for Sybase, DB2 and SQL server databases. This
functionality was designed to support graphical design and specification of
transaction workflows, sources and destinations for maps, triggering events,
and options for map execution.
 
  As of March 31, 1998, there were 47 employees in the Company's research and
development organization, more than half of which were dedicated to Mercator.
The Company's product development expenditures for 1995, 1996, 1997 and the
three months ended March 31, 1998 were $3.1 million, $3.5 million, $4.5
million and $1.2 million, respectively. The Company expects that it will
continue to commit significant resources to product development in the future.
To date, all product development expenses have been expensed as incurred.
 
  The market for the Company's products and services is characterized by
extremely rapid technological change, frequent new product introductions and
enhancements, evolving industry standards, and rapidly changing customer
requirements. The introduction of products incorporating new technologies and
the emergence of new industry standards could render existing products
obsolete and unmarketable. The Company's future success will depend in part
upon its ability to anticipate changes and enhance its current products and
develop and introduce new products that keep pace with technological
advancements and address the increasingly sophisticated needs of its
customers. See "Risk Factors -- Risks Associated with Technological Change,
Product Enhancements and New Product Development."
 
CUSTOMER SUPPORT
 
  The Company believes that a high level of customer service and support is
important to its success, and the Company provides a range of support services
to its customers. The Company maintains product and
 
                                      38
<PAGE>
 
technology experts on call at all times and has support call centers located
at its offices in Wilton, Connecticut; Bannockburn, Illinois; and Boca Raton,
Florida in the United States and in its United Kingdom office. The Company has
also implemented an automated Company-wide help desk system to augment its
customer support efforts. This system allows for the optimization of the
Company's resources and knowledge base at all locations and offers the
customer improved service through one point of contact.
 
COMPETITION
 
  The market for the Company's products and services is extremely competitive
and subject to rapid change. Because there are relatively low barriers to
entry in the software market, the Company expects additional competition from
other established and emerging companies. The Company believes that the
competitive factors affecting the market for the Company's products and
services include product functionality and features; quality of professional
services offerings; product quality, performance and price; ease of product
implementation; quality of customer support services; customer training and
documentation; and vendor and product reputation. The relative importance of
each of these factors depends upon the specific customer environment. Although
the Company believes that its products and services currently compete
favorably with respect to such factors, there can be no assurance that the
Company can maintain its competitive position against current and potential
competitors.
 
  In the enterprise application integration market, the Company's Mercator
products and related services compete primarily against solutions developed
internally by individual businesses to meet their specific enterprise
application integration needs. As a result, the Company must educate
prospective customers as to the advantages of the Company's products and
services as opposed to internally developed solutions and there can be no
assurance that the Company will be able to adequately educate potential
customers to the benefits provided by the Company's products and services. In
addition, the Company is facing increasing competition in the enterprise
application integration market from other third-party vendors. In the EDI
market, the Company's Trading Partner products compete with products offered
by companies offering proprietary VAN services as part of their EDI solution
and the Company's PC-based Trading Partner products also compete with PC-based
products offered by a number of other EDI software vendors.
 
  Many of the Company's current and potential competitors have longer
operating histories, significantly greater financial, technical, product
development and marketing resources, greater name recognition and larger
customer bases than the Company. The Company's present or future competitors
may be able to develop products comparable or superior to those offered by the
Company, adapt more quickly than the Company to new technologies, evolving
industry trends or customer requirements, or devote greater resources to the
development, promotion and sale of their products than the Company.
Accordingly, there can be no assurance that the Company will be able to
compete effectively in its markets, that competition will not intensify or
that future competition will not have a material adverse effect on the
Company's business, operating results and financial condition.
 
  The Company expects that it will face increasing pricing pressures from its
current competitors and new market entrants. The Company's competitors may
engage in pricing practices that reduce the average selling prices of the
Company's products and related services. To offset declining average selling
prices, the Company believes that it must successfully introduce and sell
enhancements to existing products and new products on a timely basis and
develop enhancements to existing products and new products that incorporate
features that can be sold at higher average selling prices. To the extent that
enhancements to existing products and new products are not developed in a
timely manner, do not achieve customer acceptance or do not generate higher
average selling prices, the Company's gross margins may decline, and such
decline could have a material adverse effect on the Company's business,
operating results and financial condition. See "Risk Factors--Competition."
 
PROPRIETARY TECHNOLOGY
 
  The Company's success is dependent upon its proprietary software technology.
The Company does not currently have any patents and relies principally on
trade secret, copyright and trademark laws, nondisclosure and other
contractual agreements and technical measures to protect its technology. The
Company also believes that factors such as the technological and creative
skills of its personnel, product enhancements and
 
                                      39
<PAGE>
 
new product developments are essential to establishing and maintaining a
technology leadership position. The Company enters into confidentiality and/or
license agreements with its employees, distributors and customers, and limits
access to and distribution of its software, documentation and other
proprietary information. There can be no assurance that the steps taken by the
Company will prevent misappropriation of its technology, and such protections
do not preclude competitors from developing products with functionality or
features similar to the Company's products. Furthermore, there can be no
assurance that third parties will not independently develop competing
technologies that are substantially equivalent or superior to the Company's
technologies. In addition, effective copyright and trade secret protection may
be unavailable or limited in certain foreign countries. Any failure by or
inability of the Company to protect its proprietary technology could have a
material adverse effect on the Company's business, operating results and
financial condition.
 
  Although the Company does not believe its products infringe the proprietary
rights of any third parties, there can be no assurance that infringement
claims will not be asserted against the Company or its customers in the
future. Furthermore, the Company may initiate claims or litigation against
third parties for infringement of the Company's proprietary rights or to
establish the validity of the Company's proprietary rights. Litigation, either
as plaintiff or defendant, would cause the Company to incur substantial costs
and divert management resources from productive tasks whether or not such
litigation is resolved in the Company's favor, which could have a material
adverse effect on the Company's business, operating results and financial
condition. Parties making claims against the Company could secure substantial
damages, as well as injunctive or other equitable relief which could
effectively block the Company's ability to license its products in the United
States or abroad. Such a judgment could have a material adverse effect on the
Company's business, operating results and financial condition. If it appears
necessary or desirable, the Company may seek licenses to intellectual property
that it is allegedly infringing. There can be no assurance, however, that
licenses could be obtained on commercially reasonable terms, if at all, or
that the terms of any offered licensed will be acceptable to the Company. The
failure to obtain the necessary licenses or other rights could have a material
adverse effect on the Company's business, operating results and financial
condition. As the number of software products in the industry increases and
the functionality of these products further overlaps, the Company believes
that software developers may become increasingly subject to infringement
claims. Any such claims, with or without merit, can be time consuming and
expensive to defend and could adversely affect the Company's business,
operating results and financial condition. The Company is not aware of any
currently pending claims that the Company's products, trademarks or other
proprietary rights infringe upon the proprietary rights of third parties. See
"Risk Factors -- Dependence on Proprietary Technology."
 
EMPLOYEES
 
  As of March 31, 1998, the Company had 192 full-time employees, including 47
in research and development, 54 in professional services and customer support,
69 in sales and marketing and 22 in finance and administration. The Company's
employees are not represented by any union and the Company believes that its
relations with employees are good. See "Risk Factors -- Dependence on Key
Personnel; Need to Attract and Retain Sales, Professional Services and
Research and Development Personnel."
 
FACILITIES
 
  The Company's principal executive offices are located in Wilton, Connecticut
and consist of approximately 19,000 square feet under a lease expiring in
2001. The Company also leases approximately 12,000 square feet of office space
in Bannockburn, Illinois which is used primarily for its telesales operations,
approximately 11,000 square feet of office space in Boca Raton, Florida, which
is used primarily for research and development activities, approximately 3,600
square feet of office space in the United Kingdom, and small offices in France
and Landover, Maryland. All of the Company's offices have fully-equipped
training centers. The Company is currently negotiating for additional leased
space at its executive offices. The Company believes its facilities are
adequate to support its current needs and, if required, the Company can obtain
additional space on a timely basis and on commercially reasonable terms.

DIRECTOR COMPENSATION
 
  The Company reimburses the members of its Board for expenses associated with
their attendance at Board meetings and at Board Committee meetings. None of
the members of the Board is entitled to receive fees for attendance at Board
meetings or at Board Committee meetings.
 
  In May 1997, the Board adopted and the Company's stockholders approved the
1997 Directors Stock Option Plan (the "Directors Plan") and reserved a total
of 225,000 shares of the Company's Common Stock for issuance thereunder.
Members of the Board who are not employees of the Company, or any parent or
subsidiary of the Company are eligible to receive stock options under the
Directors Plan. Each eligible director who is or becomes a member of the Board
on or after May 10, 1997 will automatically be granted an option for 15,000
shares. Accordingly, in May 1997, each of Messrs. Gross, Keet, Pendray and
Sisco received options to purchase 15,000 shares of Common Stock at an
exercise price of $6.67 per share. Upon each one-year anniversary of the date
such director is granted the 15,000 share option, he or she will receive an
additional option grant for 3,750 shares, provided such director has served
continuously as a member of the Board. Each 15,000 share option granted under
the Directors Plan will vest over four years as to 25% of the shares on the
last day of each twelve-month period following the date such 15,000 share
option was granted. Each 3,750 share option granted under the Directors Plan
will vest as to 100% of the shares on the last day of the twelve month period
following the date such 3,750 share option was granted. The per share exercise
price of each option granted under the Directors Plan prior to the Company's
initial public offering was the fair market value of a share of the Company's
Common Stock as determined by the Board. The per share exercise price of each
option granted after the Company's initial public offering will be equal to
the closing price of a share of the Company's Common Stock on the Nasdaq
National Market on the date of grant. Options granted under the Directors Plan
generally expire three months after the termination of the optionee's service
to the Company or a parent or subsidiary of the Company, except in the case of
death or disability, in which case the options may be exercised up to 12
months following the date of death or termination of service. In the event of
a merger, consolidation or certain other change of control transactions, the
vesting of all outstanding options granted pursuant to the Directors Plan will
accelerate and such options will become exercisable in full prior to the close
of such corporate transaction. The Directors Plan will terminate in May 2007,
unless terminated earlier in accordance with the provisions of the Directors
Plan.

(1) Unless otherwise indicated below, all options granted in 1993 were granted
    pursuant to the Company's 1993 Stock Option Plan (the "1993 Plan"), and
    vest as to 25% of the shares covered by such option each year following
    the date of grant, subject to acceleration under certain circumstances.
    Under the 1997 Plan, the Board or a committee of the Board retains
    discretion, subject to 1993 Plan limits, to modify the terms of
    outstanding options. The options have a term of ten years if the grantee
    is based in the United States and a term of seven years if the grantee is
    based in the United Kingdom subject to earlier termination in certain
    situations related to termination of employment. See "-- Employee Benefit
    Plans."
(2) Based on a total of 310,600 options granted to all employees during 1997.
(3) All options were granted at an exercise price equal to the fair market
    value of the Company's Common Stock.
(4) Potential realizable values are calculated based on the fair market value
    of the Common Stock at the date of grant minus the exercise price. The 5%
    and 10% assumed annual rates of compounded stock appreciation are mandated
    by the rules of the Securities and Exchange Commission and do not
    represent the Company's estimate or projection of future Common Stock
    price. There can be no assurance provided to any executive officer or any
    other holder of the Company's securities that the actual stock price
    appreciation over the option term will be at the assumed 5% and 10% levels
    or at any other defined level. Unless the market price of the Common Stock
    appreciates over the option term, no value will be realized from the
    option grants made to the executive officers.
 
  The following table includes information concerning unexercised stock
options held by the Named Officers at December 31, 1997. No options were

EMPLOYEE BENEFIT PLANS
 
  1997 Equity Incentive Plan. In May 1997, the Board adopted and the Company's
stockholders approved the 1997 Equity Incentive Plan (the "1997 Plan"), under
which 1,125,000 shares of the Company's Common Stock are reserved for
issuance. In addition to the 1,125,000 shares reserved for issuance
thereunder, shares that are reserved for issuance but that are not subject to
options under the Company's 1993 Stock Option Plan (the "1993 Plan") and
shares that are subject to outstanding options which either terminate without
being exercised or that are repurchased by the Company at the original issue
price will be available for issuance under the 1997 Plan. The 1997 Plan became
effective in July 1997 and will terminate in May 2007, unless terminated
earlier in accordance with the provisions of the 1997 Plan. The 1997 Plan
authorizes the award of options, opportunities to purchase restricted stock
and stock bonuses (an "Award"). The 1997 Plan is administered by a committee
appointed by the Board, currently the Compensation Committee, consisting of
Messrs. Keet, Sisco, Pendray and Gross, all of whom are non-employee directors
under applicable federal securities laws and "outside directors" as defined
under Section 162(m) of the Internal Revenue Code of 1986, as amended (the
"Code"). The Compensation Committee has the authority to construe and
interpret the 1997 Plan and any agreement made thereunder, grant Awards and
make all other determinations necessary or advisable for the administration of
the 1997 Plan.
 
                                      46
<PAGE>
 
   As of March 31, 1998, 396,200 shares of Common Stock were subject to
options outstanding under the 1997 Plan and 1,009,974 shares of Common Stock
were available for future distribution pursuant to the 1997 Plan, including
shares originally reserved for issuance under the 1993 Plan that have become
available for distribution under the 1997 Plan. Since the effectiveness of the
1997 Plan, the Company has issued 400 shares of Common Stock as Stock Bonuses.
The 1997 Plan provides for the grant of both incentive stock options ("ISOs")
that qualify under Section 422 of the Code and nonqualified stock options
("NQSOs"). ISOs may be granted only to employees of the Company or of a parent
or subsidiary of the Company. NQSOs may be granted to employees, officers,
directors, consultants, independent contractors and advisors of the Company or
any parent or subsidiary of the Company, provided such consultants,
independent contractors, and advisors render bona fide services not in
connection with the offer and sale of securities in a capital-raising
transaction ("Eligible Service Providers"). The per share exercise price of
ISOs must be at least equal to the fair market value of a share of the
Company's Common Stock on the date of grant unless the option is an ISO
granted to a stockholder owning 10% or more of the Company's capital stock in
which case the exercise price must be at least 110% of the fair market value
of the Company's Common Stock. The per share exercise price of NQSOs must be
at least 85% of the fair market value of the Company's Common Stock. The
maximum term of options granted under the 1997 Plan is ten years if the
grantee is based in the United States and a maximum term of seven years if the
grantee is based in the United Kingdom, unless the option is an ISO granted to
a stockholder owning 10% or more of the Company's stock in which case the
maximum term is five years. Options granted under the 1997 Plan may not be
transferred in any manner other than by will or by the laws of descent and
distribution and may be exercised during the lifetime of the optionee only by
the optionee. Options granted under the 1997 Plan generally expire three
months after the termination of the optionee's service to the Company or a
parent or subsidiary of the Company, except in the case of death or
disability, in which case the options may be exercised up to 12 months
following the date of death or termination of service. No person may receive
more than 300,000 shares in any calendar year pursuant to the grant of Awards
under the 1997 Plan. New employees, however, are eligible to receive Awards up
to a total of 450,000 shares in the calendar year in which they are hired.
 
  Opportunities to purchase shares of the Company's Common Stock ("Restricted
Stock Awards") and awards of shares of the Company's Common Stock ("Stock
Bonuses"), either of which may be subject to a right of repurchase in favor of
the Company or other restrictions on ownership or transfer, may be given to
Eligible Service Providers. The Compensation Committee, which is the
administrator of the 1997 Plan, has the authority to determine the
restrictions applicable to the stock. The purchase price of Common Stock sold
pursuant to a Restricted Stock Award must be at least 85% of the fair market
value of the shares on the date of grant. Awards that are granted below 100%
of fair market value are limited under the 1997 Plan. No Eligible Service
Provider may receive more than 150,000 shares pursuant to such Awards under
the 1997 Plan and no more than 300,000 shares may be issued pursuant to such
Awards for the term of the 1997 Plan.
 
  In the event of a merger, consolidation or certain other change of control
transactions, any outstanding Awards will accelerate by one-year's vesting or
such additional acceleration of vesting as the Compensation Committee in its
discretion may decide, and may be assumed or replaced by the successor
corporation. In lieu of such assumption or replacement, but in addition to the
one-year's additional vesting or such additional acceleration of vesting, the
successor corporation may substitute equivalent Awards or provide
substantially similar consideration to Eligible Service Providers as is
provided to stockholders.
 
  1993 Stock Option Plan. As of March 31, 1998, 1,194,581 shares of Common
Stock were subject to options outstanding under the 1993 Plan. No further
options will be granted under the 1993 Plan. However, all outstanding options
will remain outstanding until exercised or until they terminate or expire in
accordance with their terms. The terms of options granted under the 1993 Plan
and the administration of the 1993 Plan are substantially the same as those
that pertain to the 1997 Plan.
 
  1997 Employee Stock Purchase Plan. In May 1997, the Board adopted and the
Company's stockholders approved the 1997 Employee Stock Purchase Plan (the
"Purchase Plan") and reserved a total of 750,000 shares of the Company's
Common Stock for issuance thereunder. As of April 30, 1998, 70,662 shares
 
                                      47
<PAGE>
 
of Common Stock had been issued pursuant to the Purchase Plan and 679,338
shares remained available for future issuance under the Purchase Plan. The
Purchase Plan became effective in July 1997 and permits eligible employees to
acquire shares of the Company's Common Stock through payroll deductions.
Eligible employees may select a rate of payroll deduction between 2% and 15%
of their compensation and are subject to certain maximum purchase limitations
described in the Purchase Plan. Each offering under the Purchase Plan is for a
period of 12 months (the "Offering Period") and consists of two six-month
purchase periods (each a "Purchase Period"). The purchase price for the
Company's Common Stock purchased under the Purchase Plan is 85% of the lesser
of the closing price of the Company's Common Stock on the first day of the
applicable Offering Period and the last day of the applicable Purchase Period.
The first Offering Period began on July 1, 1997 and will end on July 31, 1998.
The Board has the power to set the beginning of any Offering Period and to
change the duration of Offering and Purchase Periods. The Purchase Plan is
intended to qualify as an "employee stock purchase plan" under Section 423 of
the Code.
 
COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION IN COMPENSATION
DECISIONS
 
  Until May 1997, the Company had no separate compensation or stock option
committee or other board committee performing equivalent functions, and these
functions were performed by the Company's Board of Directors of which
Constance F. Galley, President and Chief Executive Officer of the Company, was
and is a member. In May 1997, the Company's Board of Directors appointed a
Compensation Committee which currently consists of Stewart K.P. Gross, Ernest
E. Keet, John J. Pendray and Dennis G. Sisco, each a non-employee director of
the Company.
 
INDEMNIFICATION OF DIRECTORS AND EXECUTIVE OFFICERS AND LIMITATION OF
LIABILITY
 
  As permitted by Section 145 of the Delaware General Corporation Law, the
Bylaws of the Company provide that (i) the Company is required to indemnify
its directors and executive officers to the fullest extent permitted by the
Delaware General Corporation Law, (ii) to the fullest extent permitted by the
Delaware General Corporation Law, the Company is required to advance all
expenses, as incurred, to its directors and executive officers in connection
with a legal proceeding (subject to certain exceptions), (iii) the rights
conferred in the Bylaws are not exclusive, (iv) the Company may, in its
discretion indemnify or advance expenses to persons whom the Company is not
obligated to indemnify or advance expenses; (v) the Company is authorized to
enter into indemnification agreements with its directors, officers, employees
and agents or any person serving at the request of the Company as a director,
officer, employee or agent of another corporation, partnership, joint venture,
trust or other enterprise, including employee benefit plans and (vi) the
Company may not retroactively amend the Bylaw provisions relating to
indemnification.
 
  The Company has entered into Indemnification Agreements with each of its
current directors and executive officers to give such directors and officers
additional contractual assurances regarding the scope of the indemnification
set forth in the Company's Bylaws and to provide additional procedural
protections. At present, there is no pending litigation or proceeding
involving a director, officer or employee of the Company regarding which
indemnification is sought, nor is the Company aware of any threatened
litigation that may result in claims for indemnification.
 
  As permitted by the Delaware General Corporation Law, the Company's
Certificate of Incorporation includes a provision that eliminates the personal
liability of its directors for monetary damages for breach of fiduciary duty
as a director to the fullest extent permitted by the Delaware General
Corporation Law.
 
  As authorized by the Company's Bylaws, the Company, with approval of the
Board, has obtained directors' and officers' liability insurance.
 
  In so far as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers and controlling persons of the
Company pursuant to the foregoing provisions or otherwise, the Company 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.

director, executive officer or holder of more than 5% of any class of voting
securities of the Company or members of such person's immediate family had or
will have a direct or indirect material interest other than the compensation
agreements which are described in "Management."

 (1) Beneficial ownership is determined in accordance with the rules of the
     Securities and Exchange Commission that deem shares to be beneficially
     owned by any person who has or shares voting or investment power with
     respect to such shares. Unless otherwise indicated below, the persons and
     entities named in the table have sole voting and sole investment power
     with respect to all shares beneficially owned, subject to community
     property laws where applicable. A person is deemed to be the beneficial
     owner of securities that can be acquired by such person within 60 days of
     April 30, 1998, upon exercise of options or warrants and such securities
     are reflected in the above table. Shares of Common Stock subject to
     options and warrants that are exercisable within 60 days of April 30,
     1998 are deemed to be outstanding and to be beneficially owned by the
     person holding such options for the purpose of computing the percentage
     ownership of such person but are not treated as outstanding for the
     purpose of computing the percentage ownership of any other person.
 (2) Applicable percentage of ownership is based upon 9,542,873 shares of
     Common Stock outstanding on April 30, 1998 (giving effect to (i) 382,281
     shares of Common Stock issuable upon exercise of the Selling Stockholder
     Warrant and (ii) 11,000 shares of Common Stock issuable upon exercise of
     stock options by two of the Selling Stockholders immediately prior to the
     closing of this Offering) and 10,742,873 shares of Common Stock
     outstanding upon completion of the Offering.
 (3) Assumes that the Underwriters' over-allotment option to purchase up to
     526,650 shares from the Company and two Selling Stockholders is not

     full, the Company, Warburg, Pincus Capital & Company, L.P. and Vanguard
     Atlantic Ltd. will sell an additional 226,650, 200,000 and 100,000

                         DESCRIPTION OF CAPITAL STOCK
 
  The authorized capital stock of the Company consists of 20,000,000 shares of
Common Stock, par value $0.01 per share, and 5,000,000 shares of Preferred
Stock, par value $0.01 per share. As of March 31, 1998, there were outstanding
9,098,202 shares of Common Stock, options to purchase 1,650,781 shares of
Common Stock and Warrants to purchase 711,771 shares of Common Stock.
 
COMMON STOCK
 
  Subject to preferences that may be applicable to any Preferred Stock
outstanding at the time, the holders of outstanding shares of Common Stock are
entitled to receive dividends out of assets legally available therefor at such
times and in such amounts as the Board may from time to time determine. Each
stockholder is entitled to one vote for each share of Common Stock held on all
matters submitted to a vote of stockholders. Cumulative voting for the
election of directors is not provided for in the Company's Certificate of
Incorporation, which means that the holders of a majority of the shares voted
can elect all of the directors then standing for election. The Common Stock is
not entitled to preemptive rights and is not subject to conversion or
redemption. Upon liquidation, dissolution or winding-up of the Company, the
assets legally available for distribution to stockholders are distributable
ratably among the holders of the Common Stock and any participating Preferred
Stock outstanding at that time after payment of liquidation preferences, if
any, on any outstanding Preferred Stock and payment of other claims of
creditors. Each outstanding share of Common Stock is, and all shares of Common
Stock to be outstanding upon completion of this offering will be, fully paid
and nonassessable.
 
PREFERRED STOCK
 
  The Board is authorized, subject to any limitations prescribed by Delaware
law, to provide for the issuance of additional shares of Preferred Stock in
one or more series, to establish from time to time the number of shares to be
included in each such series, to fix the rights, preferences and privileges of
the shares of each wholly unissued series and any qualifications, limitations
or restrictions thereon, and to increase or decrease the number of shares of
any such series (but not below the number of shares of such series then
outstanding), without any further vote or action by the stockholders. The
Board may authorize the issuance of Preferred Stock with voting or conversion
rights that could adversely affect the voting power or other rights of the
holders of Common Stock. Thus, the issuance of Preferred Stock may have the
effect of delaying, deferring or preventing a change in control of the
Company. The Company has no current plan to issue any shares of Preferred
Stock.
 
WARRANTS
 
  As of March 31, 1998, the Company had outstanding seven warrants to purchase
an aggregate of 711,771 shares of Common Stock. These warrants have an
exercise price of $2.00 per share of Common Stock and expire in June and
August, 2002. These warrants are also exerciseable on a net exercise basis.
Following the consummation of this offering, there will be outstanding 269,490
shares of Common Stock issuable upon exercise of warrants.
 
REGISTRATION RIGHTS
 
  Following this offering, the holders of approximately 1,736,259 shares of
Common Stock and Warrants to purchase 269,490 shares of Common Stock of the
Company have certain "demand" rights to register those shares of Common Stock
and the shares of Common Stock issuable upon exercise of such Warrants (the
"Registrable Securities") under the Securities Act. If requested by holders of
more than 50% of the Registrable Securities then outstanding, the Company must
file a registration statement under the Securities Act covering all
Registrable Securities requested to be registered. The Company is required to
effect two such "demand" registrations pursuant to these registration rights.
The "demand" rights of any particular holder of Registrable Securities will
expire in July 2000.
 
                                      52
<PAGE>
 
  In addition, holders of Registrable Securities have certain "piggyback"
registration rights. If the Company proposes to register any of its securities
under the Securities Act other than in connection with the Company's employee
benefit plans or a corporate reorganization, the holders of Registrable
Securities may require the Company to include all or a portion of their shares
in such registration, although the managing underwriter, if any, of any such
offering has certain rights to limit the number of Registrable Securities
proposed to be included in such registration.
 
  Further, if requested by holders of more than 50% of the then outstanding
Registrable Securities (assuming there is a reasonably anticipated aggregate
offering price to the public of at least $500,000), the Company must file a
registration statement on Form S-3 with respect to the resale of such
Registrable Securities when such form becomes available to the Company,
subject to certain conditions.
 
  All expenses incurred in connection with the above registrations (other than
the underwriters' and brokers' discounts and commissions) will be borne by the
Company.
 
  The Company's obligation to register the Registrable Securities will
terminate when all such Registrable Securities have been registered and sold
or are no longer outstanding.
 
DELAWARE ANTI-TAKEOVER LAW
 
  The Company is subject to the provisions of Section 203 of the Delaware
General Corporation Law (the "Anti-Takeover Law") regulating corporate
takeovers. The Anti-Takeover Law prevents certain Delaware corporations,
including those whose securities are listed on the Nasdaq National Market,
from engaging, under certain circumstances, in a "business combination" (which
includes a merger or sale of more than 10% of the corporation's assets) with
any "interested stockholder" (a stockholder who owns 15% or more of the
corporation's outstanding voting stock) for three years following the date
that such stockholder became an "interested stockholder." A Delaware
corporation may "opt out" of the Anti-Takeover Law with an express provision
in its original certificate of incorporation or an express provision in its
certificate of incorporation or bylaws resulting from a stockholders'
amendment approved by at least a majority of the outstanding voting shares.
The Company has not "opted out" of the provisions of the Anti-Takeover Law.
 
TRANSFER AGENT AND REGISTRAR
 
  The Transfer Agent and Registrar for the Company's Common Stock is The Bank
of New York.
 
LISTING
 
  The Common Stock is listed on the Nasdaq National Market under the trading
symbol "TSFW."

                        SHARES ELIGIBLE FOR FUTURE SALE
 
  Future sales of substantial amounts of Common Stock in the public market
could adversely affect market prices prevailing from time to time. Sales of
substantial amounts of Common Stock of the Company in the public market after
the lapse of existing resale restrictions could adversely affect the
prevailing market price and the ability of the Company to raise equity capital
in the future.
 
  In general, under Rule 144 as currently in effect, a person (or persons
whose shares are aggregated) who has beneficially owned Restricted Shares for
at least one year (including the holding period of any prior owner except an
affiliate of the Company) would be entitled to sell within any three-month
period a number of shares that does not exceed the greater of: (i) one percent
of the number of shares of Common Stock then outstanding (which will equal
approximately 107,429 shares immediately after this offering); or (ii) the
average weekly trading volume of the Common Stock during the four calendar
weeks preceding the filing of a Form 144 with respect to such sale. Sales
under Rule 144 are also subject to certain manner of sale provisions and
notice requirements and to the availability of current public information
about the Company. Under Rule 144(k), a person who is not deemed to have been
an affiliate of the Company at any time during the 90 days preceding a sale,
and who has beneficially owned the shares proposed to be sold for at least two
years (including the holding period of any prior owner except an affiliate of
the Company), is entitled to sell such shares without complying with the
manner of sale, public information, volume limitation or notice provisions of
Rule 144. Unless otherwise restricted, "144(k) shares" may therefore be sold
immediately upon the completion of this offering.
 
  Upon completion of this offering, the Company will have outstanding
approximately 10,742,873 shares of Common Stock (based on shares outstanding
as of April 30, 1998). Of these shares, 8,265,838 will be eligible for
immediate sale in the public market without restriction as of the effective
date of the Registration Statement of which this Prospectus forms a part (the
"Effective Date"). On the Effective Date there will be an additional 2,477,035
shares of Common Stock outstanding, all of which additional shares are
"restricted" shares (the "Restricted Shares") under the Securities Act.
Certain stockholders of the Company are subject to lock-up agreements
providing that they will not directly or indirectly offer, sell, pledge,
contract to sell, grant any option to purchase or otherwise dispose of any
shares of Common Stock or any securities convertible into or exercisable or
exchangeable for Common Stock for a period of 90 days after the date of this
Prospectus without the prior written consent of BancAmerica Robertson
Stephens. Taking into account the lock-up agreements and notwithstanding
possible earlier eligibility for sale under the provisions of Rules 144 and
144(k), the numbers of shares that will be available for sale in the public
market will be as follows: (i) 252,930 Restricted Shares will be eligible for
sale in the public market without restriction as of the Effective Date, (ii)
150,000 Restricted Shares will be eligible for sale subject to certain volume
and other resale restrictions under Rule 144 and (iii) approximately 2,074,105
Restricted Shares will become eligible for sale 90 days after the Effective
Date upon expiration of certain lock-up agreements and, as of that date, all
of such shares will be subject to certain volume and other resale restrictions
pursuant to Rule 144. In addition, upon completion of this offering, there
will remain outstanding Warrants to purchase 269,490 shares of Common Stock at
an exercise price of $2.00 per share. These Warrants are exercisable at any
time on a net exercise basis. Accordingly, any shares of Common Stock issuable
upon such net exercise would be available for resale in the public market,
subject to public information, volume limitation or notice provisions of Rule
144, in the case of affiliates.
 
  At March 31, 1998, options to purchase 1,650,781 shares of Common Stock were
outstanding, of which options approximately 710,831 shares were then
exercisable. The Company has registered under the Securities Act a total of
3,616,671 shares of Common Stock reserved for issuance pursuant to outstanding
options under the 1993 Plan, and outstanding options or shares reserved for
issuance under the 1997 Plan, Directors Plan and Purchase Plan. As a result of
such registration, shares of Common Stock issuable upon exercise of options
and pursuant to the Purchase Plan will be available for sale in the public
market, subject to Rule 144 volume limitations applicable to affiliates and
subject to lock-up agreements. Also, certain holders of shares of Common Stock
and Warrants to purchase Common Stock are entitled to certain rights to
register such shares of Common Stock for offer and sale to the public. See
"Description of Capital Stock--Registration Rights."

  The Representatives have advised the Company and the Selling Stockholders
that the Underwriters propose to offer the shares of Common Stock to the
public at the public offering price set forth on the cover page of this
Prospectus and to certain dealers at such price less a concession of not in
excess of $0.54 per share, of which $0.10 may be reallowed to other dealers.
After the completion of this offering, the public offering price, concession
and reallowance to dealers may be reduced by the Representatives. No such
reduction shall change the amount of proceeds to be received by the Company
and the Selling Stockholders as set forth on the cover page of this
Prospectus.
 
  In connection with this offering, the Underwriters have agreed to purchase a
warrant to purchase 382,281 shares of Common Stock from a Selling Stockholder
at a per share price equal to the initial public offering price less the
underwriting discounts and commissions and the per share exercise price of
such warrant. Such warrant has an exercise price of $2.00 per share, which
will be paid to the Company by the Underwriters upon exercise at the
consummation of the offering.
 
  The Company and the Selling Stockholders have granted to the Underwriters an
option, exercisable during the 30-day period after the date of this Prospectus
for this offering, to purchase up to an aggregate of 526,650 additional shares
of Common Stock, at the same price per share as the Company and the Selling
Stockholders will receive for the 3,511,000 shares that the Underwriters have
agreed to purchase. To the extent that the Underwriters exercise such option,
each of the Underwriters will have a firm commitment to purchase approximately
the same percentage of such additional shares that the number of shares of
Common Stock to be purchased by it shown in the above table represents as a
percentage of the 3,511,000 shares offered hereby. If purchased, such
additional shares will be sold by the Underwriters on the same terms as those
on which the 3,511,000 shares are being sold.
 
  The Underwriting Agreement contains covenants of indemnity among the
Underwriters, the Company and the Selling Stockholders against certain civil
liabilities, including liabilities under the Securities Act.
 
  Pursuant to the terms of lock-up agreements, all officers, directors and
certain security holders of the Company have agreed with the Representatives
for a period of 90 days after the effective date of this Prospectus that they
will not, subject to certain exceptions, directly or indirectly offer to sell,
contract to sell,
 
                                      55

or otherwise sell, dispose of, pledge, grant any rights with respect to, any
shares of Common Stock, any options or warrants to purchase any shares of
Common Stock, or any securities convertible into or exchangeable for shares of
Common Stock, now owned or hereafter acquired directly by such holders or with
respect to which they have the power of disposition, without the prior written
consent of BancAmerica Robertson Stephens, which may, in its sole discretion
and at any time without notice, release all or any portion of the securities
subject to lock-up agreements. See "Shares Eligible for Future Sale." In
addition, the Company also has agreed that during the 90 days following the
effective date of this Prospectus the Company will not, without the prior
written consent of BancAmerica Robertson Stephens, subject to certain
exceptions, offer, issue, sell, contract to sell, or otherwise dispose of any
shares of Common Stock, any options or warrants to purchase any shares of
Common Stock, or any securities convertible into, exercisable for or
exchangeable for shares of Common Stock other than the Company's sales of
shares in this offering, the issuance of Common Stock upon the exercise of
outstanding options and the Company's issuance of options under existing
employee and director stock option plans.
 
  The Underwriters do not intend to confirm sales of the Common Stock offered
hereby to any accounts over which they exercise discretionary authority.
 
  The Representatives have advised the Company that, pursuant to Regulation M
under the Exchange Act, certain persons participating in the offering may
engage in transactions, including stabilizing bids, syndicate covering
transactions or the imposition of penalty bids which may have the effect of
stabilizing or maintaining the market price of the Common Stock at a level
above that which might otherwise prevail in the open market. A "stabilizing
bid" is a bid for or the purchase of the Common Stock on behalf of the
Underwriters for the purpose of fixing or maintaining the price of the Common
Stock. A "syndicate covering transaction" is the bid for or the purchase of
the Common Stock on behalf of the Underwriters to reduce a short position
incurred by the Underwriters in connection with the offering. A "penalty bid"
is an arrangement permitting the Representatives to reclaim the selling
concession otherwise accruing to an Underwriter or syndicate member in
connection with the offering if the Common Stock originally sold by such
Underwriter or syndicate member is purchased by the Representatives in a
syndicate covering transaction and has therefore not been effectively placed
by such Underwriter or syndicate member. The Representatives have advised the
Company that such transactions may be effected on the Nasdaq National Market
or otherwise and, if commenced, may be discontinued at any time.
 
  In connection with this offering, certain Underwriters and selling group
members (if any) who are qualified market makers on the Nasdaq National Market
may engage in passive market making transactions in the Common Stock on the
Nasdaq National Market in accordance with Rule 103 of Regulation M under the
Exchange Act, during the business day prior to the pricing of the offering,
before the commencement of offers or sales of the Common Stock. Passive market
makers must comply with applicable volume and price limitations and must be
identified as such. In general, a passive market maker must display its bid at
a price not in excess of the highest independent bid for such security; if all
independent bids are lowered below the passive market maker's bid, however,
such bid must then be lowered when certain purchase limits are exceeded.
 
                                 LEGAL MATTERS
 
  The validity of the shares of Common Stock offered hereby will be passed
upon for the Company and the Selling Stockholders by Fenwick & West LLP, Palo
Alto, California. Certain legal matters will be passed upon for the

                         INDEPENDENT AUDITORS' REPORT
 
The Board of Directors
TSI International Software Ltd.:
 
  We have audited the accompanying balance sheets of TSI International
Software Ltd. (the "Company") as of December 31, 1996 and 1997, and the
related statements of income, stockholders' equity (deficit) and cash flows
for each of the years in the three year period ended December 31, 1997. 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 generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
 
  In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of TSI International Software
Ltd. as of December 31, 1996 and 1997, and the results of its operations and
its cash flows for each of the years in the three year period ended December
31, 1997 in conformity with generally accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
 
(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
 The Company
 
  TSI International Software Ltd. (the "Company") develops, markets, licenses,
and supports computer software and related services which allow organizations
to integrate their business applications within the enterprise and with
outside business partners. The Company's customers are located primarily
throughout the U.S. and Western Europe and represent a broad range of
industries.
 
 (a) Revenue Recognition
 
  Software licensing revenues are recognized upon shipment of the product if
there are no significant post-delivery obligations, or at a later date once
such obligations are satisfied. Maintenance contract revenue is recognized
ratably over the term of the contracts, which are generally for one year. The
unrecognized portion of maintenance revenue is classified as deferred revenue
in the accompanying balance sheets which also includes software license
revenues related to customer prepayment that are not yet earned. Consulting
and training revenues are recognized as services are performed.
 
  The Company licenses its KEY/MASTER product on a term-use basis for 15 to 60
month periods. The contracts provide for maintenance and generally do not have
renewal or purchase options. At contract inception, the present value of the
payments to be received under the contract is apportioned between software
licensing revenue and maintenance revenue and recognized as described above.
The present value of the payments to be received is recorded as the investment
in licensing contracts receivable. License interest revenue is recognized over
the term of the contract at a constant rate of return.
 
 (b) Product Development Costs
 
  Statement of Financial Accounting Standards (SFAS) No. 86, "Accounting for
the Costs of Computer Software to Be Sold, Leased, or Otherwise Marketed,"
requires that software development costs: (i) be expensed as incurred until
technological feasibility (as defined therein) is achieved; and (ii)
capitalized subsequent to achieving technological feasibility and prior to the
product being available to customers. The establishment of technological
feasibility of the Company's products has essentially coincided with the
products' general release to customers. Accordingly, the Company expenses all
software development costs as incurred.
 
  Purchased software with alternative future use is capitalized and amortized
over its expected useful life.
 
 (c) Furniture, Fixtures, and Equipment
 
  Furniture, fixtures, and equipment are carried at cost less accumulated
depreciation computed using the straight-line method over their estimated
useful lives. Furniture, fixtures, and equipment held under capital leases and
leasehold improvements are amortized on a straight-line basis over the lease
term.
 
 (d) Income Taxes
 
  Deferred tax assets and liabilities are recognized for the future tax
consequences attributable to differences between the financial statement
carrying amounts of existing assets and liabilities and their respective tax
bases. Deferred tax assets and liabilities are measured using enacted tax
rates expected to apply to taxable income in the years in which those
temporary differences are expected to be recovered or settled. The effect on
deferred tax assets and liabilities of a change in tax rates is recognized in
income in the period that includes the enactment date. Valuation allowances
are provided for any portion of the deferred tax assets which are more likely
than not to be realized.

                   NOTES TO FINANCIAL STATEMENTS--CONTINUED
 
 (e) Earnings per Share
 
  In December 1997, the Company adopted Statement of Financial Accounting
Standard ("SFAS") No. 128, "Earnings Per Share." SFAS No. 128 replaced the
calculation of primary and fully diluted net income per share with basic and
diluted net income per share. Basic earnings per share is computed based upon
the weighted average number of common shares outstanding. Diluted earnings per
share is computed based upon the weighted average number of common shares
outstanding increased for any dilutive effects of options, warrants, and
convertible securities. All net income per share data for prior years has been
restated to conform with the provisions of SFAS No. 128
 
 (f) Cash Equivalents
 
  The Company considers securities with maturities of three months or less,
when purchased, to be cash equivalents.
 
 (g) Marketable Securities
 
  All marketable securities are classified as trading securities under the
provision of Statement of Financial Accounting Standard ("SFAS") No. 115,
"Accounting for Certain Investments in Debt and Equity Securities" and
unrealized holding gains and losses are reflected in earnings.
 
 (h) Long-Lived Assets
 
  During 1996, the Company adopted Statement of Financial Accounting Standard
("SFAS") No. 121, "Accounting for the Impairment of Long-Lived Assets and for
Long-Lived Assets to Be Disposed Of." SFAS No. 121 requires companies to
review assets for possible impairment and provides guidelines for recognition
of impairment losses related to long-lived assets, certain intangibles, and
assets to be disposed of. The impact of the adoption of SFAS No. 121 was not
material.
 
 (i) Stock Options
 
  Also during 1996, the Company adopted Statement of Financial Accounting
Standard ("SFAS") No. 123, "Accounting for Stock-Based Compensation." In
accordance with SFAS No. 123, the Company elected not to record any
compensation expense for stock options granted to employees at fair value and
will disclose in the notes to its financial statements the impact on net
income and net income per share as if the fair value based compensation cost
had been recognized (see note 6).
 
 (j) Use of Estimates
 
  The preparation of financial statements in accordance 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 revenue and expenses during the
reporting period. Actual results could differ from those estimates.
 
 (k) Recently Issued Accounting Standards
 
  In June 1997, Statement of Financial Accounting Standard ("SFAS") No. 131,
"Disclosures about Segments of an Enterprise and Related Information," was
issued. SFAS No. 131 establishes standards for the way that public business
enterprises report information about operating segments in annual financial
statements and requires that those enterprises report selected information
about operating segments in interim financial reports issued to shareholders
which is currently not required. It also establishes standards for related
disclosures about products and services, geographic areas, and major
customers. The Company is required to adopt this standard as of December 31,
1998.

 (1) Newly Adopted Accounting Standards (unaudited)
 
  In June 1997, Statement of Financial Accounting Standard ("SFAS") No. 130
"Reporting Comprehensive Income," was issued. SFAS No. 130 establishes
standards for reporting and disclosure of comprehensive income and its
components in a full set of general-purpose financial statements. This
statement requires that all items that are required to be recognized under
accounting standards as components of comprehensive income be reported. Other
comprehensive income for the three months ended March 31, 1997 and 1998 was
$(79,800) and $44,700, respectively, and is comprised of the change in the
foreign currency translation.
 
  In October 1997 the AICPA issued SOP 97-2, "Software Revenue Recognition",
which supersedes SOP 91-1. The Company adopted SOP 97-2 for software
transactions entered into beginning January 1, 1998. SOP 97-2 generally
requires revenue earned on software arrangements involving multiple elements,
such as additional software products, upgrades or enhancements, rights to
exchange or return software, postcontract customer support, or services,
including elements deliverable only on a when-and-if-available basis, to be
allocated to the various elements of such sale based on "vendor-specific
objective evidence of fair values" allocable to each such element.
 
  The Company has reviewed and accounted for its license agreements under the
requirements of SOP 97-2 and did not have a material effect on its results of
operations.
 
  Other pronouncements issued by the FASB or other authoritative accounting
standard groups with future effective dates are either not applicable or are
not significant to the financial statements of the Company.
 
(2) FOREIGN OPERATIONS
 
  The Company's balance sheets include foreign branch assets of $2,574,400,
$3,867,200 and $2,390,526 and liabilities of $282,200, $406,600 and $335,262
at December 31, 1996 and 1997 and (unaudited) March 31, 1998, respectively.
The foreign net income for the years ended December 31, 1995, 1996, 1997 and
(unaudited) the three months ended March 31, 1997 and 1998, after allocation
of corporate charges, was $133,700, $345,400, $45,300, $(115,600) and
$(110,900), respectively.
 
  With the exception of direct sales activities in the United Kingdom and
Canada, the Company utilizes distributors and agents to market its products
outside the United States. Revenues generated through these third parties
amounted to $147,100, $288,700 $125,400, $35,700 and $21,200 for the years
ended December 31, 1995, 1996, 1997 and (unaudited) the three months ended
March 31, 1997 and 1998, respectively.

(6) STOCKHOLDERS' EQUITY (DEFICIT)
 
 (a) Initial Public Offering
 
  On July 1, 1997, the Company sold 3,000,000 shares of common stock in an
initial public offering ("IPO") which resulted in proceeds of approximately
$24,272,300, net of offering expenses of $837,700. In connection with the
completion of the IPO, the following transactions were completed: (i) The
Company increased the number of authorized shares of common stock and
preferred stock to 20,000,000 shares and 5,000,000 shares, respectively; (ii)
the Company completed a three-for-one common stock split; (iii) all
outstanding preferred shares were converted into 2,759,715 shares of common
stock; and, (iv) certain shareholders of the Company registered and sold
1,600,000 of common stock with net proceeds to these shareholders of
$13,392,000. The accompanying financial statements have been retroactively
adjusted to reflect the common stock split.
 
  In addition, on May 15, 1997, three new investors acquired a total of 50,000
shares of Series E convertible preferred stock at $20 a share, which at
closing of the IPO converted into 150,000 shares of common stock.
 
  At December 31, 1996, certain owners of preferred and common stock held an
aggregate of nine warrants to purchase common stock at $2.00 a share. During
1997, two warrants were exercised into an aggregate of 296,827 shares. As the
warrants were exercised on a net exercise basis, no proceeds were received by
the Company. At December 31, 1997, there are seven warrants remaining which
are exercisable for 711,711 shares of common stock and expire in 2002.

  On July 1, 1997, in conjunction with the Company's initial public offering,
all preferred shares outstanding were converted into 2,759,715 shares of stock
based on the three-to-one stock split. No preferred shares were issued or

 (c) Stock Option Plans
 
  The Company maintains a 1993 Stock Option Plan ("1993 Plan") which provided
that the Company may grant options for employees to purchase up to 1,558,431
shares of the Company's common stock. In May 1997, the Board resolved that no
further options would be granted under the 1993 plan following the closing of
the Company's Initial Public Offering ("IPO"). There were 215,100 options
granted under the 1993 Plan at exercise prices ranging from $1.67 to $9.00 in
the year ended December 31, 1997 prior to the IPO. Any shares reserved for
issuance under the 1993 Plan that are not subject to outstanding options or
that are subject to outstanding options which either terminate without being
exercised or that are repurchased by the Company are available for issuance
under the 1997 Equity Incentive Stock Option Plan.
 
  The Company established the 1997 Equity Incentive Stock Option Plan ("Equity
Plan") in May 1997. The Equity Plan provides that the Company may grant
options to employees to purchase up to 1,405,074 shares of the Company's
common stock. The Company granted 35,500 options under the Plan in 1997 at
exercise prices from $6.67 to $14.375 per share. Options have been granted at
fair market value. No options may be granted for a term greater than 10 years.
 
  In addition, the Company established a Directors Stock Option Plan in May
1997 which authorizes the issuance of options to directors to purchase 225,000
shares of the Company. During 1997, 60,000 options were granted at $6.67 a
share. No options were issued during the first quarter of 1998.
 
  In addition, the Company established an Employee Stock Purchase Plan which
reserves a total of 750,000 shares of the Company's common stock for issuance
thereunder. The plan permits eligible employees to acquire shares of the
Company's common stock through payroll deductions. Eligible employees may
select a deduction of 2 to 15% of their compensation subject to certain
maximum limitations as described in the plan. The offering period began on the
date of offering and will end on July 31, 1998. As of March 31, 1998,
(unaudited) 70,662 shares had been purchased under the plan at $7.65 per share
totalling $539,900. Purchases of shares take place at six-month intervals from
the beginning date of each offering period.

a share, options were granted during 1997 at exercise prices between $1.66 to
$14.375 and (unaudited) options were granted for the three months ended March
31, 1998 at exercise prices of $11.91 and $13.70 per share. Substantially all
options vest ratably over a four-year period from the date of grant. There
were (unaudited) 1,854,312 shares available for grant at March 31, 1998.
 
  As discussed in Note 1, the Company adopted SFAS No. 123 during 1996 and
elected not to recognize compensation expense relating to employee stock
options where the exercise price of the option equaled the fair value (as
estimated by the Company) of the stock on the date of grant. As a non-public
entity prior to July 1, 1997, for the years 1995 and 1996 the Company utilized
the minimum value method to determine compensation based on the fair value of
the options on the date of grant in accordance with SFAS No. 123. Following
are the resultant pro forma amounts of net income and net income per share:

(7) EARNINGS PER SHARE
 
  In February 1997, Statement of Financial Accounting Standard ("SFAS") No.
128, "Earnings per Share" was issued. The statement sets forth guidance on the
presentation of earnings per share and requires dual presentation of Basic and
Diluted earnings per share on the face of the income statement. The
computation of basic earnings per share is based on income available to common
stockholders and the weighted average number of common shares outstanding
during each period. Diluted earnings per share reflect the potential dilution
that could occur if dilutive stock options were exercised resulting in the
issuance of common stock that then shared in the earnings of the Company. In
connection with the IPO, all outstanding preferred stock was converted into
common stock on the basis described in note 6 and, accordingly, are shown as
outstanding for the diluted earnings per share calculation for all periods
presented. Following are the components of common stock used to calculate
Basic and Diluted earnings per share:

(8) EMPLOYEE BONUS AND SAVINGS PLANS
 
  The Company maintains a bonus plan for all non-executive officer employees.
The bonus plan is reviewed annually by the Board of Directors and provides for
payments based upon a percentage of pretax income, as defined. Bonus payments
were $100,000, $200,000, and $200,000 in 1995, 1996 and 1997, respectively.
 
  On July 1, 1990, the Company established a defined contribution plan under
Section 401(k) of the Internal Revenue Code which provides for voluntary
employee salary deferrals but does not require Company matching funds. The
defined contribution plan covers substantially all employees. Employees are
eligible to contribute to the defined contribution plan upon completion of
three months of service with the Company. Contributions are subject to
established limitations as determined by the Internal Revenue Service. There
have been no Company contributions to the plan to date. As of January 1, 1998
the Company amended the plan to include an employer match of 2% of
participants' contributions up to 4%.

  At December 31, 1997, the Company had federal tax net operating loss
carryforwards of $6,849,000 expiring between the years 2000 and 2009 and
research and experimentation credits of $655,900 expiring between 2003 and
2008. Section 382 of the Internal Revenue Code imposes a limitation on the
amount of tax loss carryforwards which can be utilized in any year after there
has been a 50% or greater ownership change of the Company. The ownership
change is based on the number of shares of stock or the aggregate market value
of the stock within any consecutive three year period. Future years'
utilization of the Company's tax loss carryforwards could be subject to this
limitation.
 
  At December 31, 1996 and 1997, the components of net deferred taxes
(utilizing a 41.4% combined tax rate) were:

  Significant temporary differences which give rise to deferred tax (a)
liabilities and (b) assets are: (a) investment in licensing contracts
receivable and depreciation; and (b) net operating loss carryforwards and
deferred maintenance revenues.
 
  The decrease in the valuation allowance of $853,400 in 1997 is the result of
the utilization of net operating loss carryforwards.

Federal statutory tax rate and the Company's effective tax rate for financial
