                                    SUMMARY
 
  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
detailed information, including "Risk Factors," and the Financial Statements
and Notes thereto, appearing elsewhere in this Prospectus.
 
                                  THE COMPANY
 
  TSI International Software Ltd. ("TSI" or the "Company") is a leading
provider of software and related services that enable organizations to
integrate their business applications both internally and with external
business partners. The Company's flagship product, Mercator, is a data
transformation engine 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.
 
  TSI'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 was the first
product to be 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 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 tools
permit customers to integrate business processes across their supply and demand
chains by leveraging the Internet and other transport mechanisms for EDI.
 
  The Company's strategy is to be the market leader in providing solutions that
integrate business 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 tools and solutions for the 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. TSI has directly
licensed its products to over 6,000 customers worldwide, representing a broad
range of industries. The Company's customers include Allegiance Corporation,
American Express Travel Related Services, Inc., CIGNA Corporation, Citibank,
N.A., Federal Express Corporation, Hewlett-Packard Company, Hoechst AG,
International Business Machines Corporation, Lucent Technologies, Inc., NYNEX
Corporation and Prudential Insurance Company of America.

                                 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.
 
UNCERTAIN PROFITABILITY; ACCUMULATED DEFICIT
 
  Although the Company has been profitable since 1995, the Company incurred
significant operating losses through 1993 and, at March 31, 1997, the
Company's accumulated deficit was approximately $9.7 million. There can be no
assurance that the Company's profitability will continue. The Company
introduced its Mercator product line in December 1993 and released the latest
version of this product in May 1996. The relatively recent introduction of the
Mercator product line and the relative immaturity of its market, together with
the factors described under "-- Potential Fluctuations in Quarterly Results;
Seasonality," make the prediction of future operating results impossible. The
Company's past financial performance should not be considered indicative of
future results. Although the Company has experienced growth in revenues and
net income in recent periods, there can be no assurance that revenues or net
income will continue to increase or not decrease. Future operating results
will depend on many factors, including the growth of the market for business
application integration software and related services, demand for and market
acceptance of the Company's products and related services, particularly its
Mercator products and related services, demand for and market acceptance of
the SAP R/3 system, the level of competition, the Company's success in
expanding its direct sales force, indirect distribution channels and its
professional services business, the ability of the Company to further develop
and market its products, product enhancements and new products, general
economic conditions and other factors. See "-- Potential Fluctuations in
Operating Results; Seasonality" and "Management's Discussion and Analysis of
Financial Condition and Results of Operations."
 
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 as well as the number of such businesses
requiring third party business 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.
 
                                       6
<PAGE>
 
  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
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 professional
services and sales and marketing 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
 
                                       7
<PAGE>
 
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, 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 business 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 ALE certification for Mercator for R/3. In order to maintain such
certification, 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
 
                                       8
<PAGE>
 
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 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
 
  An integral part of the Company's strategy is to expand both its direct
sales force and 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.
 
                                       9
<PAGE>
 
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.
 
  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.
 
  The Company also plans to expand its direct sales force. The Company's
future success will depend in 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 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.
 
DEPENDENCE ON KEY PERSONNEL; NEED TO ATTRACT AND RETAIN SALES, PROFESSIONAL
SERVICES AND TECHNICAL PERSONNEL
 
  The Company's future success depends in large part on the continued service
of its key technical, professional services and sales 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, technical, professional
services and managerial personnel, particularly sales, professional services
and technical 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 technical 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 technical, professional services and
sales 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 $13.9 million in 1994 to $16.1 million in 1995 and $19.0
million in 1996 and increasing from $4.1 million for the first quarter of 1996
to $5.5 million for the comparable period of 1997. 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 days sales outstanding from December 31, 1996 to March
31, 1997 from approximately 70 days to approximately 86 days, and an increase
in total accounts receivable from $4.4 million to $5.3 million. The Company
believes this increase resulted from difficulties in implementing a new
financial accounting system which have since been resolved, and from a lack of
sufficient collections resources in light of the Company's increased sales
levels.
 
  To deal with these concerns, the Company has 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
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 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 business 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 business application integration market, the Company's Mercator
products and related services compete primarily against solutions developed
internally by individual businesses to meet their specific
 
                                      11
<PAGE>
 
business 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
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 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 "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
 
                                       12
<PAGE>
 
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 currently account for only approximately 10%
of the Company's total revenues, the Company intends to expand its sales and
marketing resources outside of the United States, which will require
significant management 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 believes that it
will be required to develop double byte versions of its products and 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.
 
                                      13
<PAGE>
 
Although the Company has corrected known material defects in its current
products and has not experienced material adverse effects resulting from any
such defects to date, 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 being pursued. There can be no assurance that the Company will be
able to successfully identify, negotiate or finance such acquisitions, 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.
 
NO PRIOR MARKET; VOLATILITY OF STOCK PRICE
 
  Prior to this offering, there has been no public market for the Company's
Common Stock, and there can be no assurance that an active public market will
develop or be sustained after this offering. The initial public offering price
will be determined by negotiations among the Company and the representatives of
the Underwriters based on several factors and may not be indicative of the
market price of the Common Stock after this offering. See "Underwriting" for a
discussion of the factors to be considered in determining the initial public
offering price. The market price of the shares of Common Stock is likely to be
highly volatile 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.
 
CONTROL BY EXISTING STOCKHOLDERS; FACTORS INHIBITING TAKEOVER
 
  Upon completion of this offering, officers, directors and affiliated entities
of the Company will beneficially own approximately  % of the outstanding Common
Stock of the Company ( % if the Underwriters' over-
 
                                       14
<PAGE>
 
allotment option is exercised in full). As a result, such persons and entities
will be able to control the management and affairs of the Company and exercise
significant influence over all matters requiring stockholder approval,
including election of directors, any merger, consolidation or sale of all or
substantially all of the Company's assets, and any other significant corporate
transaction. The concentration of ownership could have the effect of delaying
or preventing a change in control of the Company. See "Principal and Selling
Stockholders." Immediately prior to the completion of this offering, the
Company's Certificate of Incorporation will be amended and restated to include
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
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."
 
IMMEDIATE AND SUBSTANTIAL DILUTION
 
  The initial public offering price is substantially higher than the net
tangible book value per share of Common Stock. Investors purchasing shares of
Common Stock in this offering will therefore incur immediate and substantial
dilution of $    in the net tangible book value per share of the Common Stock
(at an assumed initial public offering price of $    per share and after
deducting the estimated underwriting discount and estimated offering
expenses). To the extent that options or Warrants to purchase the Company's
Common Stock are exercised, there will be further dilution. See "Dilution."
 
UNCERTAINTY AS TO USE OF PROCEEDS
 
  Except for the repayment of amounts outstanding under its credit line, the
Company has no specific plans as to the use of a significant portion of the
net proceeds from this offering, other than 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
 
  Sales of large amounts of the Company's Common Stock in the public market
could adversely affect the market price of the Common Stock and could impair
the Company's future ability to raise capital through offerings of its equity
securities. A substantial number of outstanding shares of Common Stock and
shares of Common Stock issuable upon the exercise of outstanding stock options
and Warrants will become available for resale in the public market at
prescribed times. Upon completion of this offering, there will be     shares
of Common Stock of the Company outstanding. The     shares offered hereby will
be eligible for immediate sale in the public market without restriction. No
other shares will be immediately eligible for resale in the public market
without restriction under the Securities Act of 1933, as amended (the
"Securities Act"), but     shares will be eligible for resale in the public
market pursuant to Rule 144(k) and Rule 701 of the Securities Act beginning
approximately 90 days after the effective date of this Prospectus and
shares will be eligible for resale subject to certain volume and other
restrictions of Rule 144. The Selling Stockholders, the officers and directors
of the Company and certain other stockholders, who in the aggregate will hold
upon completion of this offering     shares of Common Stock, have agreed that
they will not, without the prior written consent of Robertson, Stephens &
Company sell or otherwise dispose of any shares of Common Stock beneficially
owned by them for a period of 180 days from the effective date of this
 
                                      15
<PAGE>
 
Prospectus. Following the expiration of the 180-day lockup period (or earlier
with the consent of Robertson, Stephens & Company), these     shares will be
eligible for sale except that     shares owned by "affiliates" of the Company
as the term is defined in Rule 144 under the Securities Act in some cases will
be subject to the restrictions of Rule 144. Within 90 days after this
offering, the Company intends to register approximately 2,391,014 shares of
the Company's Common Stock reserved for issuance under its stock option plans
and stock purchase plan.
 
  Following this offering, the holders of     shares of the Company's Common
Stock and holders of Warrants to purchase 728,938 shares of Common Stock will
have certain rights to register those shares of Common Stock under the
Securities Act. See "Shares Eligible for Future Sale."
 
                                      16
<PAGE>
 
                                USE OF PROCEEDS
 
  The net proceeds to the Company from the sale of the     shares of Common
Stock offered by the Company hereby are estimated to be approximately $    (at
an assumed initial public offering price of $    per share) after deducting
the estimated underwriting discount and commissions and estimated offering
expenses. The Company will not receive any proceeds from the sale of Common
Stock by the Selling Stockholders.
 
  The Company expects to use a portion of such proceeds for the repayment of
indebtedness under the Company's bank credit line. A portion of this
indebtedness bears interest at the rate of the bank's prime lending rate plus
1.0% and the remainder bears interest at the rate of the applicable LIBOR rate
plus 3.0% (for a weighted average interest rate of approximately 8.86% at
March 31, 1997). The Company has no current specific plans for the remainder
of 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 such 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.

                                   DILUTION
 
  The pro forma net tangible book value of the Company as of March 31, 1997,
was $(2.0 million) or approximately $(0.54) per share of Common Stock. Pro
forma net tangible book value per share represents total tangible assets of
the Company, less total liabilities, divided by the number of shares of Common
Stock outstanding, assuming conversion of all outstanding shares of Preferred
Stock into an aggregate of 1,843,038 shares of Common Stock. Net tangible book
value dilution per share represents the difference between the amount per
share paid by purchasers of shares of Common Stock in the offering made hereby
and the pro forma tangible book value per share of Common Stock immediately
after the offering.
 
  After giving effect to the sale of     shares of Common Stock offered by the
Company hereby (at an assumed initial public offering price of $    per share
and after deducting the estimated underwriting discounts and commissions and
estimated offering expenses), the pro forma net tangible book value of the
Company as of March 31, 1997 would have been $    or approximately $    per
share. This represents an immediate increase in net tangible book value of
$   per share to existing stockholders and an immediate dilution of $   per
share to purchasers of Common Stock in this offering, as illustrated in the
following table:

  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 May 1996 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 three 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 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 with the goal of increasing license revenues
from sales of its products. The Company does not believe that the mix of
software licensing and service, maintenance and other revenues will change
substantially in the future.
 
 
  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, resellers and direct
sales. International revenue accounted for 10.4% and 9.4% of total revenues
for 1996 and the first three months of 1997, respectively. The Company
maintains an international sales and support office
 
                                      21
<PAGE>
 
in the United Kingdom. The Company intends to increase its international
direct sales force and focus on establishing additional international
distributor and reseller relationships. 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 in advance. Because the Company's operating expenses
are relatively fixed, a delay in the recognitions 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.
 
  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, 1997 COMPARED WITH THREE MONTHS ENDED MARCH 31,
1996
 
 Revenues
 
  Total Revenues. The Company's total revenues increased 35% from $4.1 million
in the first three months of 1996 to $5.5 million in the comparable period of
1997.
 
  Software Licensing. Software licensing revenues increased 53% from $1.8
million in the first three months of 1996 to $2.7 million in the comparable
period of 1997, primarily as a result of a 96% increase in Mercator license
revenues.
 
  Service, Maintenance and Other. Service, maintenance and other revenues
increased 20% from $2.3 million in the first three months of 1996 to $2.8
million in the comparable period of 1997, primarily as a result of a 136%
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 $1.2 million and $1.1
million for the first three months of 1996 and 1997, 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 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
 
                                      23
<PAGE>
 
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
87% from $93,000 in the first three months of 1996 to $174,000 in the
comparable period of 1997, primarily due to increased sales of software
licenses. Software licensing gross margin remained relatively constant at 95%
and 94% in the first three months of 1996 and 1997, respectively.
 
  Cost of Service, Maintenance and Other. Cost of service, maintenance and
other revenues increased 27% from $432,000 in the first three months of 1996
to $548,000 in the comparable period of 1997, primarily due to increased
professional services rendered, particularly Mercator-related services.
Service, maintenance and other gross margin remained relatively constant at
81% and 80% in the first three months of 1996 and 1997, 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 38% from $779,000 in the first three months of 1996 to $1.1 million
in the comparable period of 1997, primarily due to increased product
development activities relating to the Company's Mercator product line.
Product development expenses as a percentage of total revenue did not change
significantly in the first three months of 1997 as compared to the first three
months of 1996. 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 1997. 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 36% from $1.9 million in the first three months
of 1996 to $2.6 million in the comparable period of 1997, primarily due to the
increased number of sales and marketing personnel to address Mercator
marketing opportunities and increased expenditures for Mercator-related
marketing programs. Selling and marketing expenses as a percentage of total
revenues did not change significantly in the first three months of 1997 as
compared to the first three months of 1996. The Company expects to continue
hiring additional sales and marketing personnel and to increase promotional
expenses through at least the remainder of 1997 to address Mercator marketing
opportunities 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 7% from
$729,000 in the first three months of 1996 to $777,000 in the comparable
period of 1997, primarily due to increased administrative expenses to support
the Company's growth. General and administrative expenses as a percentage of
total revenue decreased to 14% in the first three months of 1997 from 18% for
the comparable period of 1996, primarily due to increased revenues during the
first three months of 1997. The Company believes that the dollar amount of its
general and administrative expenses will increase as the Company expands its
administrative staff and incurs additional costs (including directors' and
officers' liability insurance, investor relations programs and increased
professional fees) related to being a public company.
 
                                      24

 Other Income (Expense), Net
 
  Other income represents interest income earned on the Company's term-use
contracts and was negligible in the first three months of 1996 and 1997. Other
expense, principally interest related to the Company's bank revolving line of
credit, was $82,000 in the first three months of 1996 as compared with $69,000
in the first three months of 1997.
 
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 address
Mercator marketing opportunities and increased spending on Mercator-related
marketing programs. Selling and marketing expenses represented 44% and 46% of
total revenues for 1995 and 1996, respectively.
 
  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. Other expense decreased from $454,000 in 1995 to $320,000
in 1996, primarily due to lower interest expense caused by reduced borrowing
levels.
 
 Taxes
 
  At December 31, 1996, the Company had federal net operating loss
carryforwards of $8.6 million, all of which expire through 2009. Due to the
"change in ownership" provisions of the Internal Revenue Code of 1986, the
availability of net operating loss carryforwards and research tax credits to
offset federal taxable income in future periods could be subject to an annual
limitation if a change in ownership for income tax purposes should occur. See
Note 8 of Notes to Financial Statements.
 
YEAR ENDED DECEMBER 31, 1995 COMPARED WITH YEAR ENDED DECEMBER 31, 1994
 
 Revenues
 
  Total Revenues. Total revenues increased 15% from $13.9 million in 1994 to
$16.1 million in 1995.
 
  Software Licensing. Software licensing revenues increased 20% from $6.3
million in 1994 to $7.6 million in 1995. The increase in software licensing
revenues was primarily due to a 118% 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 11% from $7.7 million in 1994 to $8.5 million in 1995. The increase
in service, maintenance and other revenues was primarily due to increases in
revenues for annual maintenance and professional services relating to the
Company's Mercator and Trading Partner products.
 
 Cost of Revenues
 
  Cost of Software Licensing. Cost of software licensing revenues decreased
30% from $1.0 million in 1994 to $725,000 in 1995. The decrease was primarily
due to lower costs related to the roll-out of the Company's OnCall*EDI product
that occurred in 1994, for which the Company accrued $400,000 in 1994.
Software licensing gross margin increased from 84% in 1994 to 90% in 1995,
primarily due to lower costs related to the roll-out of the Company's
OnCall*EDI product.
 
  Cost of Service, Maintenance and Other. Cost of service, maintenance and
other revenues decreased 13% from $2.5 million in 1994 to $2.2 million in
1995. The decrease was primarily due to a reduction of staff supporting the
Company's mainframe-based Trading Partner and KEY/MASTER products. Service,
maintenance and other gross margin increased from 67% in 1994 to 74% in 1995,
primarily due to such staff reduction.
 
 Operating Expenses
 
  Product Development. Product development expenses increased 38% from $2.2
million in 1994 to $3.1 million in 1995, primarily due to expenses related to
the development of Mercator, particularly increased headcount devoted to
product development activities. Product development expenses represented 16%
and 19% of total revenues in 1994 and 1995, respectively.
 
  Selling and Marketing. Selling and marketing expenses increased 17% from
$6.1 million in 1994 to $7.2 million in 1995. This increase was primarily due
to an increase in sales commissions associated with increased revenues,
increased marketing activities and the establishment of a dedicated business
development group. Selling and marketing expenses represented 44% and 45% of
total revenues for 1994 and 1995, respectively.
 
                                      26
<PAGE>
 
  General and Administrative. General and administrative expenses increased 4%
from $1.9 million in 1994 to $2.0 million in 1995. This increase was primarily
due to increased personnel and expenses relating to the Company's internal
systems. General and administrative expenses represented 14% and 13% of total
revenues for 1994 and 1995, respectively.
 
 Other Income (Expense), Net
 
  Other income increased from $268,000 in 1994 to $370,000 in 1995 due to a
one-time benefit in 1995 of $177,000 from the settlement of a lawsuit in the
Company's favor, offset by a decrease in the amount of interest earned on
term-use contracts. Other expense decreased from $476,000 in 1994 to $454,000
in 1995.
 
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,
1997, 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."

</TABLE>
 
  The Company's revenues and operating expenses increased sequentially in each
quarter of 1996 and software licensing revenues decreased in the first quarter
of 1997. 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 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 as well as the number of such businesses
requiring third party business 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;
 
                                      28
<PAGE>
 
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.
 
  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 revenues because a large portion of the Company's
expenses is related to headcount that cannot be easily reduced without
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 professional
services and sales and marketing 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.
 
LIQUIDITY AND CAPITAL RESOURCES
 
  The Company has funded its operations to date primarily through private
sales of equity securities, totaling approximately $8.1 million (as of March
31, 1997), and its $4.0 million bank line of credit and cash generated from
operations. Operating activities provided (used) net cash of $1.3 million,
$1.3 million, $730,000 and $(546,000) during 1994, 1995, 1996 and the first
quarter of 1997, respectively. The Company generated net cash from 1994
through 1996 primarily as a result of its improved profitability during these
periods.
 
  Investing activities (used) net cash of $(237,000), $(354,000), $(828,000)
and $(198,000) during 1994, 1995, 1996 and the first quarter of 1997,
respectively, primarily to fund capital expenditures needed to support
expansion of the Company's business. Financing activities generated (used) net
cash of $(818,000), $(1.3 million), $(102,000) and $787,000, for 1994, 1995,
1996 and the first quarter of 1997, respectively, from (repayments) borrowings
of debt. Since December 31, 1996, the Company has experienced an increase in
accounts receivable. In March 1997, additional borrowings were required to
fund higher levels of receivables. As of March 31, 1997, the Company had
outstanding borrowings of $3.6 million under its $4.0 million bank line of
credit. See "Risk Factors--Management of Growth."
 
  As of March 31, 1997, the Company had debt obligations consisting of $3.6
million in borrowings outstanding under its bank line of credit and $115,000
of capital lease obligations. At December 31, 1996, the Company also had
commitments under operating lease agreements totalling $4.8 million through
2012, including $787,000 for 1997. See Note 10 of Notes to Financial
Statements.
 
  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, 1997, 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.

  At March 31, 1997, the Company had $79,000 in cash. Since March 31, 1997,
the Company has raised an additional $1.0 million through the sale of
Preferred Stock to Mitsui & Co., Ltd. and two other foreign investors. The
Company typically operates with a relatively small amount of cash at the end
of any quarter and meets any of its additional cash needs with its bank line
of credit that expires in November 1998. The maximum amount that can be
borrowed under the bank line of credit is $4.0 million, with borrowings
limited to a percentage of eligible accounts receivable and term contracts,
plus the amount of the bank line of credit guaranteed by the Connecticut
Development Authority ($600,000 as of March 31, 1997). 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%) and, at March 31, 1997, the weighted average interest rate on
amounts outstanding under this credit line was 8.86%. 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 is
currently in compliance with these covenants. See Note 5 of Notes to Financial
Statements.
 
  The Company believes that the net proceeds from this offering, together with
its current cash and cash equivalent balances, its line of credit and 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.

INTRODUCTION
 
  TSI is a leading provider of software and related services that enable
organizations to integrate their business applications both internally and
with external business partners. The Company's flagship product, Mercator, is
a data transformation engine which permits enterprises to exchange information
between internal systems, implement and integrate advanced client/server
applications such as SAP's R/3 ERP system and to integrate EDI data and Web-
based applications with their core business systems. To date, the Company has
directly licensed its products to over 6,000 customers worldwide, representing
a broad range of industries. The Company's customers include Allegiance
Corporation, American Express Travel Related Services, Inc., CIGNA
Corporation, Citibank, N.A., Federal Express Corporation, Hewlett-Packard
Company, Hoechst AG, International Business Machines Corporation, Lucent
Technologies, Inc., NYNEX Corporation and Prudential Insurance Company of
America.
 
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 business process
reengineering, 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 Sentry Market Research, the
typical large organization has an average of 13 different operating systems
and 10 different Database Management Systems ("DBMSs") today, as compared with
6 different operating systems and 5 different DBMSs in 1993. 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.
 
  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
 
                                      31
<PAGE>
 
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'S SOLUTION
 
  TSI develops and markets software products and related services that allow
organizations to facilitate the exchange of information between enterprise
applications as well as with external business partners. Key benefits of the
TSI solution include:
 
  Comprehensive Internal and External Solution. TSI delivers comprehensive
solutions for integrating business 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'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 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, proprietary formats, industry standard
formats such as EDI, IDocs (SAP applications) and HL7 (healthcare standard for
clinical information), 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 its ALE architecture, the
standard SAP has developed for interfacing with R/3. Mercator for R/3 extends
TSI's core Mercator product by providing tools 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.
 
                                      32
<PAGE>
 
  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 business 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 business applications within the
enterprise and between business partners. Key elements of the Company's
strategy include:
 
  Leverage and Extend Technology Leadership. TSI intends to continue to extend
its leading application integration technologies. Mercator for R/3 was the
first product certified by SAP for ALE. The Company continually seeks to
leverage its core Mercator technology by developing pre-packaged solutions for
additional third party applications, data formats, DBMSs, messaging systems
and computing platforms. The Company is the leading provider of Windows-based
EDI software and has recently introduced Trading Partner PC/32, the first 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. In addition to its core Mercator products, 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 its direct sales force, TSI is
creating marketing programs to focus 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. TSI intends to
expand these third-party channels in both domestic and international markets
in addition to continuing to expand its direct sales force.
 
  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 Mercator and Trading Partner customers.
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 expects
its service offerings to be focused on opportunities and projects which the
Company believes can lead to widespread deployments of Mercator within an
enterprise. The Company intends to augment its own service offerings by
seeking strategic relationships with major system integrators and other
service providers.

 Mercator Products
 
  The Company's flagship Mercator family of products is an integrated set of
tools used by IT professionals to integrate data between different business
applications. Mercator was initially released in December 1993 and, as of March
31, 1997, had been licensed to more than 870 customers worldwide.
 
  Mercator. Mercator enables application integration by transforming or mapping
data between and among the unique 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 Execution 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 must license an
Execution Engine for each platform. The Company currently offers Execution
Engines for Window 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 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 R/3
integration. Mercator for R/3 was the first software product to be certified by
SAP for use with its ALE architecture. Mercator for R/3 extends the core
Mercator product by providing tools 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.
 
 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.
 
                                       34
<PAGE>
 
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 1989, 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, TSI 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 Compaq Computer Corporation, International Business Machines
Corporation, J.C. Penney Company, Inc., Sears, Roebuck and Company, Target
Stores and Wal-Mart Stores, Inc. The Company's OnCall*EDI products are a
series of EDI kits for electronic purchasing for the health care provider
market and has been licensed to more than 1,100 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. Trading Partner EC and its
predecessor product have been licensed to more than 200 businesses worldwide.
 
 KEY/MASTER
 
  In addition to the Company's applications integration products described
above, the Company's 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 to
meet the needs of its current installed base.
 
 Services
 
  Professional Services. TSI offers consulting and professional services to
customers who wish to have the Company's professionals plan, design or
implement their 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, TSI 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.
 
CUSTOMERS
 
  As of March 31, 1997, TSI had directly licensed its software to more than
6,000 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.

SALES AND MARKETING
 
 Sales
 
  TSI 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, 1997, the Company's sales organization consisted of 49
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, 1997, approximately 45 third parties had agreements with the
Company to resell, embed or otherwise bundle the Company's products with their
offerings in the United States. See "Risk Factors -- Dependence Upon
Development of Distribution Channels."
 
  The Company markets its products and services outside of North America
through a sales office located in the United Kingdom and through indirect
channels. Although revenues from international customers were approximately
10% of the Company's total revenues during 1996 and the first quarter of 1997,
the international market is important to the Company, and it intends to expand
its sales and marketing efforts
 
                                      36
<PAGE>
 
outside North America by adding distributors and additional sales staff. See
"Risk Factors--Risks Associated with International Expansion."
 
 Marketing
 
  TSI 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 maintains an Alliance Program designed to support its channel partners
with a variety of programs, incentives, support plans and an annual
conference. As of March 31, 1997, 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 Execution Engines for map execution. A map is an executable module that
describes the required transformation and re-ordering of data between source
and 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
19 different execution environments.

[Set forth on this page is an oval shaped graphic. Within the oval are two
rectangular boxes each with a caption heading, top to bottom, "Authoring System"
and "Execution Engine." Also within the oval is an oval with a caption "Map
Object" with a line from each of the boxes. The oval has an additional oval,
labeled "Transaction Workflow Management" surrounding it and three additional
ovals below the oval, connected by lines, labeled "Adapters," "Importers" and
"Application Solutions," from left to right, respectively.]
 
                             [GRAPH APPEARS HERE]
 
  Descriptions of source and destination objects are entered by the user
through Mercator's graphical interface. To simplify data definition, the
Company provides pre-packaged objects for a number of commonly used data
standards and the Company also provides importers for creating objects from
higher level (meta) data definitions. 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 have been defined, 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 Execution Engine appropriate to the target platform. Target platforms
currently supported include 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 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. Adapters are currently available for ODBC-compliant
databases, Oracle7 databases, and SAP's ALE. The Company is developing
adapters for additional databases and messaging systems including MQSeries,
IBM's enterprise messaging software. Importers are currently available for
COBOL copybooks, database tables for ODBC-compliant and Oracle7 databases, and
R/3 IDocs. In addition, the Company provides pre-packaged data objects for
national and international standards for EDI 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
Execution Engines by providing adapters for communicating with SAP's ALE
architecture and importers for R/3 data definitions ("IDocs"). Other TSI
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, TSI customers can use Mercator
to create their own applications where embedded data transformation is a
requirement.
 
PRODUCT DEVELOPMENT
 
  Since inception, TSI 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 intends to add a graphical
transaction workflow management tool to the core set of Mercator capabilities.
This tool is designed to support graphical design and specification of
transaction workflows, sources and destinations for maps, triggering events,
and options for map execution. In addition, during the second half of 1997,
the Company intends to release a scaleable client/server electronic commerce
offering based on Mercator technology.
 
  As of March 31, 1997, there were 40 employees in the Company's research and
development organization, more than half of which was dedicated to Mercator.
The Company's product development expenditures for 1994, 1995, 1996 and the
first quarter of 1997 were $2.2 million, $3.1 million, $3.4 million and $1.1
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
 
  TSI 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 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 is currently installing
an automated Company-wide help desk system to augment its customer support
efforts. This system is currently expected to be implemented during the third
quarter of 1997.
 
                                      39
<PAGE>
 
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 business application integration market, the Company's Mercator
products and related services compete primarily against solutions developed
internally by individual businesses to meet their specific business
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
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 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
 
                                      40
<PAGE>
 
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 "Risk Factors --
Dependence on Proprietary Technology."
 
EMPLOYEES
 
  As of March 31, 1997, the Company had 151 full-time employees, including 40
in research and development, 34 in professional services and customer support,
59 in sales and marketing and 18 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
Technical Personnel."
 
FACILITIES
 
  TSI'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 8,500 square feet of office space in Boca Raton, Florida, which
is used primarily for research and development activities and approximately
3,200 square feet of office space in the United Kingdom. All of the Company's
offices have fully-equipped training centers. The Company believes that its
existing facilities are adequate to support its current needs and that, if
needed, suitable additional facilities will be available 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 Company adopted and the Company's stockholders approved the
1997 Directors Stock Option Plan (the "Directors Plan") and reserved a total
of 150,000 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 10,000
shares. Accordingly, each of Messrs. Gross, Keet, Pendray and Sisco received
options to purchase 10,000 shares of Common Stock in May 1997. Upon each one-
year anniversary of the date such director is granted the 10,000 share option,
he or she will receive an additional option grant for 2,500 shares, provided
such director has served continuously as a member of the Board. Each 10,000
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 10,000 share option was granted. Each 2,500 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 2,500 share option was
granted. Each option granted under the Directors Plan prior to the effective
date of this offering will be granted at a per share exercise price equal to
the fair market value of a share of the Company's Common Stock as determined
by the Board. Each option granted after the effective date of this offering
will be granted at a per share exercise price 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 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. 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 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) Options granted in 1996 vest as to twenty-five percent (25%) of the shares
    covered by such option each year following the date of grant, subject to
    acceleration under certain circumstances. Under the 1993 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 100,000 options granted to all employees during 1996.
(3) All options were granted at an exercise price equal to the fair market
    value of the Company's Common Stock as determined by the Board on the date
    of the grant. The Company's Common Stock was not publicly traded at the
    time of the option grants.
(4) Potential realizable values are calculated based on the fair market value
    of the Common Stock at the date of grant (which is assumed to be the
    assumed initial public offering price of $    per share) and 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.
(5) On May 8, 1997, Ms. Galley was granted an option under the 1993 Plan to
    purchase 75,000 shares of Common Stock at an exercise price of $10.00 per
    share. This option expires on May 8, 2007.
 
  The following table sets forth information concerning unexercised options
held at December 31, 1996 with respect to each of the Named Officers. No

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 750,000 shares of the Company's Common Stock are reserved for issuance.
In addition to the 750,000 shares reserved for issuance thereunder, shares
that are reserved for issuance but that are not subject to options under 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.
No options have been issued under the 1997 Plan. The 1997 Plan will become
effective on the effective date of the Registration Statement of which this
Prospectus is a part 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.
 
  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. The per share exercise price of
NQSOs must be at least 85% of the fair market value of the Company's Common
Stock 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 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
 
                                      47
<PAGE>
 
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 200,000 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 300,000 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 100,000 shares pursuant to such Awards under the 1997 Plan and no
more than 200,000 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 changes 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. Under the 1993 Plan, 1,038,954 shares of Common Stock
are or have been reserved for issuance under currently outstanding options. In
May 1997 when the 1997 Plan was adopted, the Board resolved that no further
options shall be granted under the 1993 Plan following the closing of this
offering. 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 plan
are substantially the same as those that pertain to the 1997 Plan.
 
  Profit Participation Plan. The Board maintains the TSI International Software
Ltd. Profit Participation Plan (the "Profit Plan") which allows the Board at
the end of the Company's year-end audit to vote to contribute a portion of the
Company's profits to a profit participation pool which does not include
executive officers or directors of the Company. Distributions from the pool are
usually made to eligible employees in two equal installments, one distribution
upon completion of the fiscal year-end audit and the second distribution at the
end of the next fiscal year. All employees who are employed by the Company at
the end of the fiscal year and who are employed at the time of the
distributions are eligible to receive such a distribution. Employees who are
not employed by the Company for the full fiscal year are eligible to receive
pro-rated distributions based upon the number of months worked in such fiscal
year. Payments under the profit participation pool amounted to $35,000,
$100,000 and $150,000 in 1994, 1995 and 1996, respectively.
 
  401(k) Plan. The Board maintains the TSI International Software Ltd. 401(k)
Saving and Retirement Plan (the "401(k) Plan"), a defined contribution profit-
sharing plan intended to qualify under Section 401 of the Code. All employees
who are at least 21 years old and have been employed by the Company for three
months are eligible to participate in the 401(k) plan. An eligible employee of
the Company may begin to participate in the 401(k) Plan on the first day of the
month coinciding with or following the date on which such employee meets the
eligibility requirements.
 
  A participating employee may make pre-tax contributions, subject to
limitations under the Code, of a percentage (not less than 1% but not to exceed
15%) of his or eligible compensation. Employee contributions and the investment
earnings thereon are fully vested at all times. The Company, at its discretion,
may make matching contributions for the benefit of eligible employees. Forty
percent (40%) of the Company's
 
                                       48
<PAGE>
 
contributions and the investment earnings thereon become vested upon the
employee's completion of two years of service with the Company and an
additional twenty percent (20%) for each year of service thereafter.
 
  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 500,000 shares of the Company's
Common Stock for issuance thereunder. The Purchase Plan will become effective
upon the effective date of the Registration Statement of which this Prospectus
is a part and will permit 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 will be for a period of
12 months (the "Offering Period") and will consist 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. For the
purposes of the first Offering Period, eligible employees will be able to
acquire shares at 85% of the lesser of the price at which the shares are
offered to the public in this offering or the closing price of the shares on
the last day of the applicable purchase period in the first Offering Period.
The first Offering Period is expected to begin on the first business day
following the effective date of this Registration Statement and to end on July
31, 1998. The Board of Directors 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
 
  During 1996, 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 intends to enter 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.
 
                                      49
<PAGE>
 
  As authorized by the Company's Bylaws, the Company, with approval of the
Board, is seeking, and expects to obtain, 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.

                             CERTAIN TRANSACTIONS
 
  Since January 1, 1994, there has not been, nor is there currently proposed,
any transaction or series of similar transactions to which the Company was or
is to be a party in which the amount involved exceeds $60,000 and in which any
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 (i) the
compensation agreements which are described in "Management," and (ii) the
transactions described below.
 
  From November 1990 until October 1994, Saydean Zeldin, the Company's Vice
President, Research and Development, was a consultant to the Company and a
General Partner at DownEast Partners, a consulting company. Payments to
DownEast Partners for the year ended December 31, 1994 were $122,000.
Edward Watson, the Company's Executive Vice President, Business Development,
was a General Partner of DownEast Partners until January 1994.
 
  From August 1992 to April 1994, the Company subleased its Bannockburn,
Illinois office facility from a subsidiary of Dun & Bradstreet (now Cognizant
Corporation), a holder of more than 5% of the Company's outstanding capital
stock. Payments under the sub-lease were $66,100 for the year ended December
31, 1994. The Company also subleased $130,000 of furniture and fixtures from
the same subsidiary of Dun & Bradstreet (now Cognizant Corporation). The
transaction was accounted for as a capital lease and bore interest at 9% and
required monthly payments of $4,100 through August 1995.
 
  The Company believes that all of the transactions set forth above were made
on terms no less favorable to the Company than could have been obtained from
unaffiliated third parties. All future transactions between the Company and
its officers, directors and principal stockholders and their affiliates will
be approved by a majority of the Board, including a majority of the
independent and disinterested directors of the Board, and will be on terms no
less favorable to the Company than could be obtained from unaffiliated third
parties.

                          DESCRIPTION OF CAPITAL STOCK
 
  Upon the closing of this offering, the authorized capital stock of the
Company will consist 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. Upon
the consummation of this offering, and assuming the conversion of each
outstanding share of Preferred Stock into Common Stock, there will be
outstanding      shares of Common Stock and Warrants to purchase 728,938 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
 
  Upon the closing of this offering, all outstanding shares of Preferred Stock
(the "Convertible Preferred"), will be converted into shares of Common Stock.
See Note 6 of Notes to Financial Statements for a description of the
Convertible Preferred. 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, 1997, the Company had outstanding nine Warrants to purchase
shares of the Company's reserved, but unissued shares of Series D Convertible
Preferred Stock. These Warrants, which will survive the closing of this
offering, will become exercisable into an aggregate of 728,938 shares of Common
Stock. These Warrants have an exercise price of $3.00 per share of Common Stock
and expire in June and August, 2002.
 
REGISTRATION RIGHTS
 
  Certain investors holding Convertible Preferred (which will be converted into
an aggregate of 1,843,038 shares of Common Stock) and Warrants to purchase
728,938 shares of Common Stock of the Company have certain "demand" rights to
register the shares of Common Stock issuable upon conversion of the Convertible
Preferred and upon exercise of such Warrants to the extent any of such shares
are not included in this offering (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 three years after the consummation
of the Company's initial public offering.
 
                                       54
<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 Company has applied to list its Common Stock on the Nasdaq National
Market under the trading symbol "TSFW."

                        SHARES ELIGIBLE FOR FUTURE SALE
 
  Prior to this offering, there has been no market for the Common Stock of the
Company. 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, beginning 90 days after
the date of this Prospectus, a person (or persons whose shares are aggregated)
who has beneficially owned Restricted Shares for at least one year (including
the holding period of any prior owner except an affiliate 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     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.
 
  Rule 701 permits resales of shares in reliance upon Rule 144 but without
compliance with certain restrictions, including the holding period requirement,
of Rule 144. Any employee, officer or director of or consultant to the Company
who purchased his or her shares pursuant to a written compensatory plan or
contract may be entitled to rely on the resale provisions of Rule 701. Rule 701
permits affiliates to sell their Rule 701 shares under Rule 144 without
complying with the holding period requirements of Rule 144. Rule 701 further
provides that non-affiliates may sell such shares in reliance on Rule 144
without having to comply with the holding period, public information, volume
limitation or notice provisions of Rule 144. In both cases, a holder of Rule
701 shares is required to wait until 90 days after the date of this Prospectus
before selling such shares.
 
  Upon completion of this offering, the Company will have outstanding
approximately     shares of Common Stock. In addition to the   shares of Common
Stock offered hereby, as of the effective date of the Registration Statement of
which this Prospectus forms a part (the "Effective Date"), there will be an
additional     shares of Common Stock outstanding,     of which 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 180 days after the date of this Prospectus without the
prior written consent of Robertson, Stephens & Company LLC. Taking into account
the lock-up agreements and notwithstanding possible earlier eligibility for
sale under the provisions of Rules 144, 144(k) and 701, the numbers of shares
that will be available for sale in the public market will be as follows: (i) no
Restricted Shares will be eligible for sale as of the Effective Date, (ii)
approximately     Restricted Shares will become eligible for sale 90 days after
the Effective Date pursuant to the provisions of Rule 144 or Rule 701, and
(iii) approximately    additional Restricted Shares will become eligible for
sale 180 days after the Effective Date upon expiration of certain lock-up
agreements and, as of that date, approximately     of such shares will be
subject to certain volume and other resale restrictions pursuant to Rule 144.
 
  At March 31, 1997, options to purchase 735,238 shares of Common Stock were
outstanding, of which options approximately 392,238 shares were then
exercisable. Immediately after this offering, the Company
 
                                       56
<PAGE>
 
intends to file a registration statement on Form S-8 under the Securities Act
covering an aggregate of 2,391,014 shares of Common Stock reserved for
issuance pursuant to outstanding options under the 1993 Plan, and 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. Beginning 180 days after the Effective Date,
shares issuable upon the exercise of vested options will be eligible for sale
in the public market, if such options are exercised.

  The Representatives have advised the Company that the Underwriters propose
to offer the shares of Common Stock to the public at the initial 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 $   per share, of
which $   may be reallowed to other dealers. After the initial public
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 as set forth on the cover page of
this Prospectus.
 
  Certain of 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   additional shares of Common Stock, at
the same price per share as the Company and the Selling Stockholders will
receive for the    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   shares offered hereby. If purchased, such additional shares will be sold
by the Underwriters on the same terms as those on which the   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 180 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, 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 Robertson, Stephens & Company, which may, in its
sole discretion and at any time without notice, release all or any portion of
the securities
 
                                      58
<PAGE>
 
subject to lock-up agreements. See "Shares Eligible for Future Sale." In
addition, the Company also has agreed that during the 180 days following the
effective date of this Prospectus the Company will not, without the prior
written consent of Robertson, Stephens & Company, 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.
 
  Prior to this offering, there has been no public market for the Common Stock
of the Company. Consequently, the initial public offering price for the Common
Stock was determined through negotiations among the Company and the
Representatives. Among the factors considered in such negotiations were
prevailing market conditions, certain financial information of the Company,
market valuations of other companies that the Company and the Representatives
believe to be comparable to the Company, estimates of the business potential
of the Company, the present state of the Company's development and other
factors deemed relevant.
 
  The Underwriters do not intend to confirm sales of the Common Stock offered
hereby to any accounts over which they exercise discretionary authority.
 
  The Underwriters have reserved approximately     shares of Common Stock for
sale, at the initial public offering price, to directors, officers and
employees of the Company, their business affiliates and related parties, in
each case as such persons have expressed an interest in purchasing such shares
in the offering. The number of shares of Common Stock available for sale to
the general public will be reduced to the extent such persons purchase such
reserved shares of Common Stock. Any reserved shares of Common Stock not so
purchased will be offered by the Underwriters to the general public on the
same basis as the other shares of Common Stock offered pursuant to the
offering.
 
                                 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
Underwriters by Testa, Hurwitz & Thibeault, LLP, Boston, Massachusetts.

                          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 1995, and the related
statements of operations, stockholders' (deficiency) and cash flows for each of
the years in the three year period ended December 31, 1996. 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 1995, and the results of its operations and
its cash flows for each of the years in the three year period ended December
31, 1996 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
maintenance revenue in the accompanying balance sheets. 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 are 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 not more
likely than not to be realized.

 (e) Net Income (Loss) Per Share
 
  Net income (loss) per share is usually calculated using the weighted average
number of common and common equivalent shares outstanding during each period,
after retroactive adjustment for stock splits (see note 6). In addition, the
Securities and Exchange Commission requires that shares issued within one year
of an Initial Public Offering (IPO) be shown as outstanding for all periods
presented. Further, in connection with an IPO, all outstanding preferred stock
will be converted into common stock on the basis described in note 6 and,
accordingly, are shown as outstanding for all periods presented. Following are
the components of common stock used to calculate net income (loss) per share:

</TABLE>
 
 (f) Cash Equivalents
 
  The Company considers securities with maturities of three months or less,
when purchased, to be cash equivalents.
 
 (g) 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.
 
 (h) Accounting Changes
 
  During 1996, the Company adopted 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.
 
  Also during 1996, the Company adopted 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).

(2) FOREIGN OPERATIONS
 
  The Company's balance sheets include foreign branch assets of $1,565,100,
$2,574,400, and $2,642,600 and liabilities of $258,800, $282,200, and $270,700
at December 31, 1995 and 1996, and (unaudited) March 31, 1997, respectively.
The foreign net income (loss) for the years ended December 31, 1994, 1995, and
1996, and (unaudited) the three months ended March 31, 1996 and 1997, after
allocation of corporate charges, was ($106,700), $133,700, $586,200, $129,600,
and $(115,600) 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 $230,400, $147,100, $288,700, $91,500, and $35,700 for the years
ended December 31, 1994, 1995, and 1996, and (unaudited) for the three months
ended March 31, 1996 and 1997 respectively.
 
(3) INVESTMENT IN LICENSING CONTRACTS
 
  The net investment in licensing contracts at December 31, 1996 is comprised
of future minimum contract payments receivable, net of unearned interest
income. The interest rate implicit in term-use licensing contracts was 9.5%
for contracts entered into during the years 1995 and 1996 and (unaudited) for
the first quarter of 1997. Total minimum contract payments receivable at
December 31, 1996 are as follows:

totals, net of accumulated depreciation, was $203,000, $56,200, and $64,300 as
of December 31, 1995 and 1996 and (unaudited) March 31, 1997, respectively.
 
 (b) Purchased Software
 
  In 1990, the Company acquired software from Foretell Corporation which was
available for sale to customers at the time of purchase. The cost of
$1,484,200 was amortized over a five year period which ended in 1995.
Amortization expense for years 1994 and 1995 was $291,000 and $272,100,
respectively.
 
(5) LONG-TERM DEBT
 
  Since August 1994, the Company has had a line of credit facility with a
bank. The underlying loan agreement, as amended, which expires in November
1998 and is partially guaranteed by the Connecticut Development Authority
(CDA): (a) provides for Company borrowings equal to the lesser of $4,000,000
or the sum of: (i) 80% of eligible accounts receivable, (ii) lesser
percentages of certain other receivables; and (iii) the effective dollar
amount of the guarantee of the CDA (approximately $600,000); (b) requires
interest on borrowings at either the bank's prime rate plus 1.0% or the LIBOR
rate plus 3.0%; (c) collateralizes all assets of the Company as security for
the borrowings; (d) requires the Company to maintain several financial
covenants; and (e) imposes other restrictions, including (i) prohibition on
losses, cash dividends and key management changes and (ii) limitations on
additional debt, mergers and acquisitions, stock repurchases and sales of
assets (except in the normal course of business). The Company was in
compliance with all financial covenants at December 31, 1996 but (unaudited)
was not in compliance with the indebtedness to EBITDA ratio covenant at March
31, 1997. The Company has received a waiver for this non-compliance.
 
  All repayments are due at maturity. Borrowings based on prime can be prepaid
without penalty.
 
  Borrowing costs and effective interest rates under this agreement were as

 (a) Recent Developments
 
  On May 8, 1997, the Board of Directors approved an IPO of the Company's
common stock and in connection therewith also approved at the closing of the
IPO: (i) an increase in the number of authorized shares of common stock and
preferred stock to 20,000,000 shares and 5,000,000 shares, respectively; and
(ii) a two-for-one common stock split. The accompanying financial statements
have been retroactively adjusted to reflect this common stock split. Pursuant
to the Company's Certificate of Incorporation, the closing of the IPO will
cause the conversion of all preferred shares into 1,843,038 shares of common
stock.

  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, 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:
 
<TABLE>

                                                              1995      1996

  The pro forma effect on net income for 1995 and 1996 is not representative
of the pro forma effect on net income in future years because it does not take
into consideration pro forma compensation expense related to grants made prior
to 1995.
 
  The fair value of each option granted in 1995 and 1996 was $.31 and $1.31,
respectively based on estimates on the date of grant using the modified Black-
Scholes option pricing model using the following weighted average assumptions:

(7) 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
of $40,000, $100,000, and $200,000 were authorized during 1994, 1995, and
1996, 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.
 
(8) INCOME TAXES
 
  The provision for income taxes is composed solely of Federal Alternative
Minimum Taxes (AMT). The AMT for the Company's fiscal year ended April 30,
1995 of $13,200 was prorated to calendar 1994 ($8,800) and 1995 ($4,400). The
AMT for the period May 1 to December 31, 1995 was approximately $32,000. The
AMT for the year ended December 31, 1996 was approximately $36,200.
 
  At December 31, 1996, the Company had: (a) federal tax net operating loss
carryforwards of $8,646,000 expiring between the years 2000 and 2009; (b)
research and experimentation credits of $590,000 expiring between 2003 and
2008; and (c) AMT credit carryforwards of $68,100 which have no expiration
date. 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, 1995 and 1996, 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 $503,300 in 1996 is the result of
the utilization of net operating loss carryforwards.
 
(9) ACCRUED EXPENSES
 
  Included in accrued expenses as of December 31, 1995 and 1996 and
(unaudited) March 31, 1997 are compensation costs (regular payroll, bonus and
profit sharing) of $336,500, $548,300 and $804,200, respectively.
 
(10) COMMITMENTS AND CONTINGENCIES
 
  The Company rents premises and furniture, fixtures and equipment under
operating leases which expire at various dates through 2010.
 
  Future minimum payments, by year and in the aggregate, under operating and

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
 
  As permitted by the Delaware General Corporation Law, the Registrant'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 permitted by Section 145 of the Delaware General
Corporation Law, the Bylaws of the Registrant provide that (i) the Registrant
is required to indemnify its directors and executive officers and the
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 Registrant 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 Registrant may, in its
discretion indemnify or advance expenses to persons whom the Registrant is not
obligated to indemnify or advance expenses; (v) the Registrant is authorized
to enter into indemnification agreements with its directors, officers,
employees and agents or any person serving at the request of the Registrant as
a director, officer, employee or agent of another corporation, partnership,
joint venture, trust or other enterprise, including employee benefit plans and
(vi) the Registrant may not retroactively amend the Bylaw provisions relating
to indemnification.
 
  The Registrant intends to enter into indemnity agreements with each of its
directors and executive officers. The indemnity agreements provide that
directors and executive officers will be indemnified and held harmless to the
fullest possible extent permitted by law including against all expenses
(including attorneys' fees), judgments, fines and settlement amounts paid or
reasonably incurred by them in any action, suit or proceeding, including any
derivative action by or in the right of the Registrant, on account of their
services as directors, officers, employees or agents of the Registrant or as
directors, officers, employees or agents of any other company or enterprise
when they are serving in such capacities at the request of the Registrant. The
Registrant will not be obligated pursuant to the agreements to indemnify or
advance expenses to an indemnified party with respect to proceedings or claims
(i) initiated by the indemnified party and not by way of defense, except with
respect to a proceeding authorized by the Board and successful proceedings
brought to enforce a right to indemnification under the indemnity agreements,
(ii) for any amounts paid in settlement of a proceeding unless the Registrant
consents to such settlement; (iii) on account of any suit in which judgment is
rendered against the indemnified party for an accounting of profits made from
the purchase or sale by the indemnified party of securities of the Registrant
pursuant to the provisions of (S)16(b) of the
 
                                     II-1
<PAGE>
 
Securities Exchange Act of 1934 and related laws; (iv) on account of conduct
by an indemnified party that is finally adjudged to have been in bad faith or
conduct that the indemnified party did not reasonably believe to be in, or not
opposed to, the best interests of the Registrant; (v) on account of any
criminal action or proceeding arising out of conduct that the indemnified
party had reasonable cause to believe was unlawful; or (vi) if a final
decision by a court having jurisdiction in the matter shall determine that
such indemnification is not lawful.
 
  The indemnity agreement requires a director or executive officer to
reimburse the Registrant for expenses advanced only to the extent it is
ultimately determined that the director or executive officer is not entitled,
under Delaware law, the Bylaws, his or her indemnity agreement or otherwise to
be indemnified for such expenses. The indemnity agreement provides that it is
not exclusive of any rights a director or executive officer may have under the
Certificate of Incorporation, Bylaws, other agreements, any majority-in-
interest vote of the stockholders or vote of disinterested directors, Delaware
law, or otherwise.
 
  The indemnification provision in the Bylaws, and the indemnity agreements
entered into between the Registrant and its directors and executive officers,
may be sufficiently broad to permit indemnification of the Registrant's
directors and executive officers for liabilities arising under the Securities
Act.
 
  As authorized by the Registrant's Bylaws, the Registrant, with approval by
the Registrants Board, has is seeking, and expects to obtain, directors and
officers liability insurance.

Registration Statement regarding relevant indemnification provisions described

granted under the Registrant's stock option plan and issuances to independent
contractors were made pursuant to the exemption from the registration
requirements of the Securities Act afforded by Rule 701 promulgated under the
Securities Act.
 
  All other sales were made in reliance on Registration S promulgated under
the Securities Act or Section 4(2) of the Securities Act and/or Regulation D
promulgated under the Securities Act. This sale was made to three purchasers,
two of which are affiliated, in connection with a distribution arrangement
without general solicitation or advertising. The purchasers were not United
States residents and were sophisticated investors with access to all relevant
information necessary to evaluate the investment who represented to the
Registrant that the shares were being acquired for investment.

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

462(b) of the Rules and Regulations have been delivered to you.

        If the registration statement relating to the Shares has been declared
effective under the Act by the Commission, the Company will prepare and promptly
file with the Commission the information omitted from the registration statement
pursuant to Rule 430A(a) or, if Robertson, Stephens & Company LLC, on behalf of
the several Underwriters, shall agree to the utilization of Rule 434 of the
Rules and Regulations, the information required to be included in any term sheet
filed pursuant to Rule 434(b) or (c), as applicable, of the Rules and
Regulations pursuant to subparagraph (1), (4) or (7) of Rule 424(b) of the Rules
and Regulations or as part of a post-effective amendment to the registration
statement (including a final form of prospectus). If the registration statement
relating to the Shares has not been declared effective under the Act by the
Commission, the Company will prepare and promptly file an amendment to the
registration statement, including a final form of prospectus, or, if Robertson,
Stephens & Company LLC, on behalf of the several Underwriters, shall agree to
the utilization of Rule 434 of the Rules and Regulations, the information
required to be included in any term sheet filed pursuant to Rule 434(b) or (c),
as applicable, of the Rules and Regulations. The term "Registration Statement"
as used in this Agreement shall mean such registration statement, including

Regulations); provided, however, that if in reliance on Rule 434 of the Rules
              --------  -------
and Regulations and with the consent of Robertson, Stephens & Company LLC, on
behalf of the several Underwriters, the Company shall have provided to the

to Rule 434(d) of the Rules and Regulations). Notwithstanding the foregoing, if
any revised prospectus shall be provided to the Underwriters by the Company for
use in connection with the offering of the Shares that differs from the
prospectus referred to in the immediately preceding sentence (whether or not
such revised prospectus is required to be filed with the Commission pursuant to
Rule 424(b) of the Rules and Regulations), the term "Prospectus" shall refer to

use of any Preliminary Prospectus or instituted proceedings for that purpose,
and each such Preliminary Prospectus has conformed in all material respects to
the requirements of the Act and the Rules and Regulations and, as of its date,
has not included any untrue statement of a material fact or omitted to state a
material fact necessary to make the statements therein, in the light of the
circumstances under which they were made, not misleading; and at the time the
Registration Statement became or becomes, as the case may be, effective and at
all times subsequent thereto up to and on the Closing Date (hereinafter defined)

(2) full business days prior to the Closing Date. If the Representatives so
elect, delivery of the Firm Shares may be made by credit through full fast
transfer to the accounts at The Depository Trust Company designated by the
Representatives.

     It is understood that you, individually, and not as the Representatives of
the several Underwriters, may (but shall not be obligated to) make payment of
the purchase price on behalf of any Underwriter or Underwriters whose check or
checks shall not have been received by you prior to the Closing Date for the
Firm Shares to be purchased by such Underwriter or Underwriters. Any such
payment by you shall not relieve any such Underwriter or Underwriters of any of
its or their obligations hereunder.

     After the Registration Statement becomes effective, the several
Underwriters intend to make an initial public offering (as such term is
described in Section 12 hereof) of the Firm Shares at an initial public offering
price of $_____ per share. After the initial public offering, the several
Underwriters may, in their discretion, vary the public offering price.

     The information set forth in the last paragraph on the front cover page
(insofar as such information relates to the Underwriters), on the inside front
cover concerning stabilization and over-allotment by the Underwriters, and under
the _____ and _____ paragraphs under the caption "Underwriting" in any
Preliminary Prospectus and in the Prospectus constitutes the only information
furnished by the Underwriters to the Company for inclusion in any Preliminary
Prospectus, the Prospectus or the Registration Statement, and you, on behalf of
the respective Underwriters, represent and warrant to the Company and the
Selling Stockholders that the statements made therein do not include any untrue
statement of a material fact or omit to state a material fact required to be
stated therein or necessary to make the statements therein, in the light of the
circumstances under which they were made, not misleading.

     5. Further Agreements of the Company. The Company agrees with the several
        ---------------------------------
Underwriters that:

     (a) The Company will use its best efforts to cause the Registration
Statement and any amendment thereof, if not effective at the time and date that
this Agreement is executed and delivered by the parties hereto, to become
effective as promptly as possible; the Company will use its best efforts to
cause any abbreviated registration statement pursuant to Rule 462(b) of the
Rules and Regulations as may be required subsequent to the date the Registration
Statement is declared effective to become effective as promptly as possible; the
Company will notify you, promptly after it shall receive notice thereof, of the
time when the Registration Statement, any subsequent amendment to the
Registration Statement or any abbreviated registration statement has become
effective or any supplement to the Prospectus has been filed; if the Company
omitted information from the Registration Statement at the time it was
originally declared effective in reliance upon Rule 430A(a) of the Rules and
Regulations, the Company will provide evidence satisfactory to you that the
Prospectus contains such information and has been filed, within the time period
prescribed, with the Commission pursuant to subparagraph (1) or (4) of Rule
424(b) of the Rules and Regulations or as part of a post-effective amendment to
such Registration Statement as originally declared effective which is declared
effective by the Commission; if the Company files a term sheet pursuant to Rule
434 of the Rules and Regulations, the Company will provide evidence satisfactory
to you that the Prospectus and term sheet meeting the requirements of Rule
434(b) or (c), as applicable, of the Rules and Regulations, have been filed,
within the time period prescribed, with the Commission pursuant to subparagraph
(7) of Rule 424(b) of the Rules and Regulations; if for any reason the filing of
the final form of Prospectus is required under Rule 424(b)(3) of the Rules and
Regulations, it will provide evidence satisfactory to you that the Prospectus
contains such information and has been filed with the Commission within the time
period prescribed; it will notify you promptly of any request by the Commission
for the amending or supplementing of the Registration Statement or the
Prospectus or for additional information; promptly upon your request, it will
prepare and file with the Commission any amendments or supplements to the
Registration Statement or Prospectus which, in the opinion of counsel for the
several Underwriters ("Underwriters' Counsel"), may be necessary or advisable in
connection with the distribution of the Shares by the Underwriters; it will
promptly prepare and file with the Commission, and promptly notify you of the
filing of, any amendments or supplements to the Registration Statement or
Prospectus which may be necessary to correct any statements or omissions, if, at
any time when a prospectus relating to the Shares is required to be delivered
under the Act, any event shall have occurred as a result of which the Prospectus
or any other prospectus relating to the Shares as then in effect would include
any untrue statement of a material fact or omit to state a material fact
necessary to make the statements therein, in the light of the circumstances
under which they were made, not misleading; in case any Underwriter is required
to deliver a prospectus nine (9) months or more after the effective date of the
Registration Statement in connection with the sale of the Shares, it will
prepare promptly upon request, but at the expense of such Underwriter, such
amendment or amendments to the Registration Statement and such prospectus or
prospectuses as may be necessary to permit compliance with the requirements of
Section 10(a)(3) of the Act; and it will file no amendment or supplement to the
Registration Statement or Prospectus which shall not previously have been
submitted to you a reasonable time prior to the proposed filing thereof or to
which you shall reasonably object in writing, subject, however, to compliance
with the Act and the 
<PAGE>
 
                                     -17-

Rules and Regulations and the provisions of this Agreement.

     (b) The Company will advise you, promptly after it shall receive notice or
obtain knowledge, of the issuance of any stop order by the Commission suspending
the effectiveness of the Registration Statement or of the initiation or threat
of any proceeding for that purpose; and it will promptly use its best efforts to
prevent the issuance of any stop order or to obtain its withdrawal at the
earliest possible moment if such stop order should be issued.

     (c) The Company will use its best efforts to qualify the Shares for
offering and sale under the securities laws of such jurisdictions as you may
designate and to continue such qualifications in effect for so long as may be
required for purposes of the distribution of the Shares, except that the Company
shall not be required in connection therewith or as a condition thereof to
qualify as a foreign corporation or to execute a general consent to service of
process in any jurisdiction in which it is not otherwise required to be so
qualified or to so execute a general consent to service of process. In each
jurisdiction in which the Shares shall have been qualified as above provided,
the Company will make and file such statements and reports in each year as are
or may be required by the laws of such jurisdiction.

     (d) The Company will furnish to you, as soon as available, and, in the case
of the Prospectus and any term sheet or abbreviated term sheet under Rule 434,
in no event later than the first (1st) full business day following the first day

Prospectus, the Prospectus and any amendments or supplements to such documents,
including any prospectus prepared to permit compliance with Section 10(a)(3) of
the Act, all in such quantities as you may from time to time reasonably request.

of the several Underwriters, shall agree to the utilization of Rule 434 of the

Prospectus updated in all respects through the date specified by you in such
quantities as you may from time to time reasonably request.

     (e) The Company will make generally available to its securityholders as
soon as practicable, but in any event not later than the forty-fifth (45th) day

anniversary of the effective date of the Registration Statement, an earnings
statement (which will be in reasonable detail but need not be audited) complying
with the provisions of Section 11(a) of the Act and covering a twelve (12) month
period beginning after the effective date of the Registration Statement.

     (f) During a period of five (5) years after the date hereof, the Company
will furnish to its shareholders as soon as practicable after the end of each
respective period, annual reports (including financial statements audited by
independent certified public accountants) and unaudited quarterly reports of
operations for each of the first three quarters of the fiscal year, and will
furnish to you and the other several Underwriters hereunder, upon request (i)
concurrently with furnishing such reports to its shareholders, statements of
operations of the Company for each of the first three (3) quarters in the form

<PAGE>
 
                                     -18-

together with statements of operations, of shareholders' equity, and of
cash flows of the Company for such fiscal year, accompanied by a copy of the
certificate or report thereon of independent certified public accountants, (iii)
as soon as they are available, copies of all reports (financial or other) mailed

financial statements furnished to or filed with the Commission, any securities
exchange or the National Association of Securities Dealers, Inc. ("NASD"), (v)
every material press release and every material news item or article in respect
of the Company or its affairs which was generally released to shareholders or
prepared by the Company or any of its subsidiaries, and (vi) any additional
information of a public nature concerning the Company or its subsidiaries, or
its business which you may reasonably request. During such five (5) year period,
if the Company shall have active subsidiaries, the foregoing financial
statements shall be on a consolidated basis to the extent that the accounts of
the Company and its subsidiaries are consolidated, and shall be accompanied by
similar financial statements for any significant subsidiary which is not so
consolidated.

     (g) The Company will apply the net proceeds from the sale of the Shares
being sold by it in the manner set forth under the caption "Use of Proceeds" in
the Prospectus.

     (h) The Company will maintain a transfer agent and, if necessary under the
jurisdiction of incorporation of the Company, a registrar (which may be the same
entity as the transfer agent) for its Common Stock.

     (i) The Company will file Form SR in conformity with the requirements of
the Act and the Rules and Regulations.

     (j) If the transactions contemplated hereby are not consummated by reason
of any failure, refusal or inability on the part of the Company or any Selling
Stockholder to perform any agreement on their respective parts to be performed
hereunder or to fulfill any condition of the Underwriters' obligations
hereunder, or if the Company shall terminate this Agreement pursuant to Section
12(a) hereof, or if the Underwriters shall terminate this Agreement pursuant to
Section 12(b)(i), the Company will reimburse the several Underwriters for all
out-of-pocket expenses (including fees and disbursements of Underwriters'
Counsel) incurred by the Underwriters in investigating or preparing to market or
marketing the Shares.

     (k) If at any time during the ninety (90) day period after the Registration
Statement becomes effective, any rumor, publication or event relating to or
affecting the Company shall occur as a result of which in your opinion the
market price of the Common Stock has been or is likely to be materially affected
(regardless of whether such rumor, publication or event necessitates a
supplement to or amendment of the Prospectus), the Company will, after written
notice from you advising the Company to the effect set forth above, forthwith
prepare, consult with you concerning the substance of and disseminate a press
release or other public statement, reasonably satisfactory to you, responding to
or commenting on such rumor, publication or event.

     (l) During the Lock-up Period, the Company will not, without the prior
written consent of Robertson Stephens & Company LLC, effect the Disposition of,
directly or indirectly, any Securities other than the sale of the Firm Shares to

                                     -19-

Company's issuance of options or Common Stock under the Company's presently
authorized 1993 Stock Option Plan (the "Option Plan").

     (m) During a period of ninety (90) days from the effective date of the
Registration Statement, the Company will not file a registration statement
registering shares under the Option Plan or other employee benefit plan.

           6.  Expenses.
               --------

               (a) The Company and the Selling Stockholders agree with each
Underwriter that:

                   (i) The Company and the Selling Stockholders will pay and
           bear all costs and expenses in connection with the preparation,
           printing and filing of the Registration Statement (including
           financial statements, schedules and exhibits), Preliminary
           Prospectuses and the Prospectus and any amendments or supplements
           thereto; the printing of this Agreement, the Agreement Among
           Underwriters, the Selected Dealer Agreement, the Preliminary Blue Sky
           Survey and any Supplemental Blue Sky Survey, the Underwriters'
           Questionnaire and Power of Attorney, and any instruments related to
           any of the foregoing; the issuance and delivery of the Shares
           hereunder to the several Underwriters, including transfer taxes, if
           any, the cost of all certificates representing the Shares and
           transfer agents' and registrars' fees; the fees and disbursements of
           counsel for the Company; all fees and other charges of the Company's
           independent certified public accountants; the cost of furnishing to
           the several Underwriters copies of the Registration Statement
           (including appropriate exhibits), Preliminary Prospectus and the
           Prospectus, and any amendments or supplements to any of the
           foregoing; NASD filing fees and the cost of qualifying the Shares
           under the laws of such jurisdictions as you may designate (including
           filing fees and fees and disbursements of Underwriters' Counsel in
           connection with such NASD filings and Blue Sky qualifications); and
           all other expenses directly incurred by the Company and the Selling
           Stockholders in connection with the performance of their obligations
           hereunder. Any additional expenses incurred as a result of the sale
           of the Shares by the Selling Stockholders will be borne collectively
           by the Company and the Selling Stockholders. The provisions of this
           Section 6(a)(i) are intended to relieve the Underwriters from the
           payment of the expenses and costs which the Selling Stockholders and
           the Company hereby agree to pay, but shall not affect any agreement
           which the Selling Stockholders and the Company may make, or may have
           made, for the sharing of any of such expenses and costs. Such
           agreements shall not impair the obligations of the Company and the
           Selling Stockholders hereunder to the several Underwriters.

                   (ii) In addition to its other obligations under Section 9(a)
           hereof, the Company agrees that, as an interim measure during the
           pendency of any claim, action, investigation, inquiry or other
           proceeding described in Section 9(a) hereof, it will reimburse the
           Underwriters on a monthly basis for all reasonable legal or other
           expenses incurred in connection with investigating or defending any
           such claim, action, investigation, inquiry or other proceeding,
           notwithstanding the absence of a judicial determination as to the
           propriety 
<PAGE>
 
                                     -20-

           and enforceability of the Company's obligation to reimburse the
           Underwriters for such expenses and the possibility that such payments
           might later be held to have been improper by a court of competent
           jurisdiction. To the extent that any such interim reimbursement
           payment is so held to have been improper, the Underwriters shall
           promptly return such payment to the Company together with interest,
           compounded daily, determined on the basis of the prime rate (or other
           commercial lending rate for borrowers of the highest credit standing)
           listed from time to time in The Wall Street Journal which represents
           the base rate on corporate loans posted by a substantial majority of
           the nation's thirty (30) largest banks (the "Prime Rate"). Any such
           interim reimbursement payments which are not made to the Underwriters
           within thirty (30) days of a request for reimbursement shall bear
           interest at the Prime Rate from the date of such request.

                   (iii) In addition to their other obligations under Section
           9(b) hereof, each Selling Stockholder agrees that, as an interim
           measure during the pendency of any claim, action, investigation,
           inquiry or other proceeding described in Section 9(b) hereof relating
           to such Selling Stockholder, it will reimburse the Underwriters on a
           monthly basis for all reasonable legal or other expenses incurred in
           connection with investigating or defending any such claim, action,
           investigation, inquiry or other proceeding, notwithstanding the
           absence of a judicial determination as to the propriety and
           enforceability of such Selling Stockholder's obligation to reimburse
           the Underwriters for such expenses and the possibility that such
           payments might later be held to have been improper by a court of
           competent jurisdiction. To the extent that any such interim
           reimbursement payment is so held to have been improper, the
           Underwriters shall promptly return such payment to the Selling
           Stockholders, together with interest, compounded daily, determined on
           the basis of the Prime Rate. Any such interim reimbursement payments
           which are not made to the Underwriters within thirty (30) days of a
           request for reimbursement shall bear interest at the Prime Rate from
           the date of such request.

               (b) In addition to their other obligations under Section 9(c)
hereof, the Underwriters severally and not jointly agree that, as an interim
measure during the pendency of any claim, action, investigation, inquiry or
other proceeding described in Section 9(c) hereof, they will reimburse the
Company and each Selling Stockholder on a monthly basis for all reasonable legal
or other expenses incurred in connection with investigating or defending any
such claim, action, investigation, inquiry or other proceeding, notwithstanding
the absence of a judicial determination as to the propriety and enforceability
of the Underwriters' obligation to reimburse the Company and each such Selling
Stockholder for such expenses and the possibility that such payments might later
be held to have been improper by a court of competent jurisdiction. To the
extent that any such interim reimbursement payment is so held to have been
improper, the Company and each such Selling Stockholder shall promptly return
such payment to the Underwriters together with interest, compounded daily,
determined on the basis of the Prime Rate. Any such interim reimbursement
payments which are not made to the Company and each such Selling Stockholder
within thirty (30) days of a request for reimbursement shall bear interest at
the Prime Rate from the date of such request.
<PAGE>
 
                                      -21-



           (c)   It is agreed that any controversy arising out of the operation
of the interim reimbursement arrangements set forth in Sections 6(a)(ii),
6(a)(iii) and 6(b) hereof, including the amounts of any requested reimbursement
payments, the method of determining such amounts and the basis on which such
amounts shall be apportioned among the reimbursing parties, shall be settled by
arbitration conducted under the provisions of the Constitution and Rules of the
Board of Governors of the New York Stock Exchange, Inc. or pursuant to the Code
of Arbitration Procedure of the NASD. Any such arbitration must be commenced by
service of a written demand for arbitration or a written notice of intention to
arbitrate, therein electing the arbitration tribunal. In the event the party
demanding arbitration does not make such designation of an arbitration tribunal
in such demand or notice, then the party responding to said demand or notice is
authorized to do so. Any such arbitration will be limited to the operation of
the interim reimbursement provisions contained in Sections 6(a)(ii), 6(a)(iii)
and 6(b) hereof and will not resolve the ultimate propriety or enforceability of
the obligation to indemnify for expenses which is created by the provisions of
Sections 9(a), 9(b) and 9(c) hereof or the obligation to contribute to expenses
which is created by the provisions of Section 9(e) hereof.

     7.    Conditions of Underwriters' Obligations. The obligations of the
           ---------------------------------------
several Underwriters to purchase and pay for the Shares as provided herein shall
be subject to the accuracy, as of the date hereof and the Closing Date and any
later date on which Option Shares are to be purchased, as the case may be, of
the representations and warranties of the Company and the Selling Stockholders
herein, to the performance by the Company and the Selling Stockholders of their
respective obligations hereunder and to the following additional conditions:

           (a)   The Registration Statement shall have become effective not
later than 2:00 P.M., San Francisco time, on the date following the date of this
Agreement, or such later date as shall be consented to in writing by you; and no
stop order suspending the effectiveness thereof shall have been issued and no
proceedings for that purpose shall have been initiated or, to the knowledge of
the Company, any Selling Stockholder or any Underwriter, threatened by the
Commission, and any request of the Commission for additional information (to be
included in the Registration Statement or the Prospectus or otherwise) shall
have been complied with to the satisfaction of Underwriters' Counsel.

           (b)   All corporate proceedings and other legal matters in connection
with this Agreement, the form of Registration Statement and the Prospectus, and
the registration, authorization, issue, sale and delivery of the Shares, shall
have been reasonably satisfactory to Underwriters' Counsel, and such counsel
shall have been furnished with such papers and information as they may
reasonably have requested to enable them to pass upon the matters referred to in
this Section.

           (c)   Subsequent to the execution and delivery of this Agreement and
prior to the Closing Date, or any later date on which Option Shares are to be
purchased, as the case may be, there shall not have been any change in the
condition (financial or otherwise), earnings, operations, business or business
prospects of the Company and its subsidiaries considered as one enterprise from
that set forth in the Registration Statement or Prospectus, which, in your sole
judgment, is
<PAGE>
 
                                      -22-

material and adverse and that makes it, in your sole judgment, impracticable or
inadvisable to proceed with the public offering of the Shares as contemplated by
the Prospectus.

           (d)   You shall have received on the Closing Date and on any later
date on which Option Shares are to be purchased, as the case may be, the
following opinion of counsel for the Company and the Selling Stockholders, dated
the Closing Date or such later date on which Option Shares are to be purchased
addressed to the Underwriters and with reproduced copies or signed counterparts
thereof for each of the Underwriters, to the effect that:

     under the laws of the jurisdiction of its incorporation;

     business as a foreign corporation and is in good standing in each
     jurisdiction, if any, in which the ownership or leasing of its properties
     or the conduct of its business requires such qualification, except where
     the failure to be so qualified or be in good standing would not have a
     material adverse effect on the condition (financial or otherwise),
     earnings, operations or business of the Company and its subsidiaries
     considered as one enterprise. To such counsel's knowledge, the Company does
     not own or control, directly or indirectly, any corporation, association or
     other entity other than [list subsidiaries];

                 (iv)  The authorized, issued and outstanding capital stock of
     the Company is as set forth in the Prospectus under the caption

                 (v)   All issued and outstanding shares of capital stock of
     each subsidiary of the Company have been duly authorized and validly issued
     and are fully paid and nonassessable, and, to such counsel's knowledge,

     security interest, encumbrance, claim or equitable interest;

                 (vi)  The Firm Shares or the Option Shares, as the case may be,
     to be issued by the Company pursuant to the terms of this Agreement have
     been duly authorized and, upon issuance and delivery against payment
     therefor in accordance with the terms hereof, will be duly and validly
     issued and fully paid and nonassessable, and will not have
<PAGE>
 
                                      -23-

     been issued in violation of or subject to any preemptive right, co-sale
     right, registration right, right of first refusal or other similar right.

                 (vii)  The Company has the corporate power and authority to

     enforceable in accordance with its terms, except insofar as indemnification
     provisions may be limited by applicable law and except as enforceability
     may be limited by bankruptcy, insolvency, reorganization, moratorium or
     similar laws relating to or affecting creditors' rights generally or by
     general equitable principles;

                 (ix)   The Registration Statement has become effective under
     the Act and, to such counsel's knowledge, no stop order suspending the
     effectiveness of the Registration Statement has been issued and no
     proceedings for that purpose have been instituted or are pending or
     threatened under the Act;

                 (x)    The Registration Statement and the Prospectus, and each
     amendment or supplement thereto (other than the financial statements
     (including supporting schedules) and financial data derived therefrom as to

     the Registration Statement, complied as to form in all material respects
     with the requirements of the Act and the applicable Rules and Regulations;

                 (xi)   The information in the Prospectus under the caption

     of law or legal conclusions, has been reviewed by such counsel and is a
     fair summary of such matters and conclusions; and the forms of certificates

<PAGE>
 
                                      -25-


     Stockholder; the Power of Attorney and Custody Agreement of each Selling
     Stockholder has been duly executed and delivered by or on behalf of such
     Selling Stockholder; and the Power of Attorney and Custody Agreement of
     each Selling Stockholder constitutes the valid and binding agreement of
     such Selling Stockholder, enforceable in accordance with its terms, except
     as the enforcement thereof may be limited by bankruptcy, insolvency,

     creditors' rights generally or by general equitable principles;

     Stockholder that is not a natural person and has been duly executed and
     delivered by or on behalf of each Selling Stockholder; and

                 (xxii) Upon the delivery of and payment for the Shares as
     contemplated in this Agreement, each of the Underwriters will receive valid
     marketable title to the Shares purchased by it from such Selling
     Stockholder, free and clear of any pledge, lien, security interest,
     encumbrance, claim or equitable interest. In rendering such opinion, such
     counsel may assume that the Underwriters are without notice of any defect
     in the title of the Shares being purchased from the Selling Stockholders.

           In addition, such counsel shall state that such counsel has
participated in conferences with officials and other representatives of the
Company, the Representatives, Underwriters' Counsel and the independent
certified public accountants of the Company, at which such conferences the
contents of the Registration Statement and Prospectus and related matters were
discussed, and although they have not verified the accuracy or completeness of
the statements contained in the Registration Statement or the Prospectus,
nothing has come to the attention of such counsel which leads them to believe
that, at the time the Registration Statement became effective and at all times
subsequent thereto up to and on the Closing Date and on any later date on which
Option Shares are to be purchased, the Registration Statement and any amendment
or supplement thereto (other than the financial statements including supporting
schedules and other financial and statistical information derived therefrom, as
to which such counsel need express no comment) contained any untrue statement of
a material fact or omitted to state a material fact required to be stated
therein or necessary to make the statements therein not misleading, or at the
Closing Date or any later date on which the Option Shares are to be purchased,
as the case may be, the Registration Statement, the Prospectus and any amendment
or supplement thereto (except as aforesaid) contained any untrue statement of a
material fact or omitted to state a material fact necessary to make the
statements therein, in the light of the circumstances under which they were
made, not misleading.

           Counsel rendering the foregoing opinion may rely as to questions of
law not involving the laws of the United States or the States of California and
Delaware upon opinions of local counsel, and as to questions of fact upon
representations or certificates of officers of the
<PAGE>
 
                                     -26-

Company, the Selling Stockholders or officers of the Selling Stockholders (when
the Selling Stockholder is not a natural person), and of government officials,
in which case their opinion is to state that they are so relying and that they
have no knowledge of any material misstatement or inaccuracy in any such
opinion, representation or certificate. Copies of any opinion, representation or
certificate so relied upon shall be delivered to you, as Representatives of the
Underwriters, and to Underwriters' Counsel.

           (e)   You shall have received on the Closing Date and on any later
date on which Option Shares are to be purchased, as the case may be, an opinion
of Testa, Hurwitz & Thibeault, LLP, in form and substance satisfactory to you,
with respect to the sufficiency of all such corporate proceedings and other
legal matters relating to this Agreement and the transactions contemplated
hereby as you may reasonably require, and the Company shall have furnished to
such counsel such documents as they may have requested for the purpose of
enabling them to pass upon such matters.

           (f)   You shall have received on the Closing Date and on any later
date on which Option Shares are to be purchased, as the case may be, a letter
from KPMG Peat Marwick LLP addressed to the Underwriters, dated the Closing Date
or such later date on which Option Shares are to be purchased, as the case may
be, confirming that they are independent certified public accountants with
respect to the Company within the meaning of the Act and the applicable
published Rules and Regulations and based upon the procedures described in such
letter delivered to you concurrently with the execution of this Agreement
(herein called the "Original Letter"), but carried out to a date not more than
five (5) business days prior to the Closing Date or such later date on which
Option Shares are to be purchased, as the case may be, (i) confirming, to the
extent true, that the statements and conclusions set forth in the Original
Letter are accurate as of the Closing Date or such later date on which Option
Shares are to be purchased, as the case may be, and (ii) setting forth any
revisions and additions to the statements and conclusions set forth in the
Original Letter which are necessary to reflect any changes in the facts
described in the Original Letter since the date of such letter, or to reflect
the availability of more recent financial statements, data or information. The
letter shall not disclose any change in the condition (financial or otherwise),
earnings, operations, business or business prospects of the Company and its
subsidiaries considered as one enterprise from that set forth in the
Registration Statement or Prospectus, which, in your sole judgment, is material
and adverse and that makes it, in your sole judgment, impracticable or
inadvisable to proceed with the public offering of the Shares as contemplated by
the Prospectus. The Original Letter from KPMG Peat Marwick, LLP shall be
addressed to or for the use of the Underwriters in form and substance
satisfactory to the Underwriters and shall (i) represent, to the extent true,
that they are independent certified public accountants with respect to the
Company within the meaning of the Act and the applicable published Rules and
Regulations, (ii) set forth their opinion with respect to their examination of
the consolidated balance sheet of the Company as of December 31, 1996 and
related consolidated statements of operations, shareholders' equity, and cash
flows for the twelve (12) months ended December 31, 1996, (iii) state that KPMG
Peat Marwick, LLP has performed the procedures set out in Statement on Auditing
Standards No. 71 ("SAS 71") for a review of interim financial information and
providing the report of KPMG Peat Marwick, LLP as described in SAS 71 on the
financial statements for each of the quarters in the [one] [two]-quarter period
ended [March 31, 1997] [June 30, 1997] (the "Quarterly Financial Statements"),
(iv) state that in the course of such review, nothing came to their attention
that leads
<PAGE>
 
                                     -27-

them to believe that any material modifications need to be made to any of the
Quarterly Financial Statements in order for them to be in compliance with
generally accepted accounting principles consistently applied across the periods
presented, and (v) address other matters agreed upon by KPMG Peat Marwick, LLP
and you. In addition, you shall have received from KPMG Peat Marwick, LLP a
letter addressed to the Company and made available to you for the use of the
Underwriters stating that their review of the Company's system of internal
accounting controls, to the extent they deemed necessary in establishing the
scope of their examination of the Company's consolidated financial statements as
of December 31, 1996, did not disclose any weaknesses in internal controls that
they considered to be material weaknesses.

           (g)   You shall have received on the Closing Date and on any later
date on which Option Shares are to be purchased, as the case may be, a
certificate of the Company, dated the Closing Date or such later date on which
Option Shares are to be purchased, as the case may be, signed by the Chief
Executive Officer and Chief Financial Officer of the Company, to the effect
that, and you shall be satisfied that:

                 (i)   The representations and warranties of the Company in this
           Agreement are true and correct, as if made on and as of the Closing
           Date or any later date on which Option Shares are to be purchased, as
           the case may be, and the Company has complied with all the agreements
           and satisfied all the conditions on its part to be performed or
           satisfied at or prior to the Closing Date or any later date on which
           Option Shares are to be purchased, as the case may be;

                 (ii)  No stop order suspending the effectiveness of the
           Registration Statement has been issued and no proceedings for that
           purpose have been instituted or are pending or threatened under the
           Act;

                 (iii) When the Registration Statement became effective and at
           all times subsequent thereto up to the delivery of such certificate,
           the Registration Statement and the Prospectus, and any amendments or
           supplements thereto, contained all material information required to
           be included therein by the Act and the Rules and Regulations and in
           all material respects conformed to the requirements of the Act and
           the Rules and Regulations, the Registration Statement, and any
           amendment or supplement thereto, did not and does not include any
           untrue statement of a material fact or omit to state a material fact
           required to be stated therein or necessary to make the statements
           therein not misleading, the Prospectus, and any amendment or

           they were made, not misleading, and, since the effective date of the
           Registration Statement, there has occurred no event required to be
           set forth in an amended or supplemented Prospectus which has not been
           so set forth; and

                 (iv)  Subsequent to the respective dates as of which
           information is given in the Registration Statement and Prospectus,
           there has not been (a) any material adverse change in the condition
           (financial or otherwise), earnings, operations, business or business
<PAGE>
 
                                     -28-

           prospects of the Company and its subsidiaries considered as one
           enterprise, (b) any transaction that is material to the Company and
           its subsidiaries considered as one enterprise, except transactions
           entered into in the ordinary course of business, (c) any obligation,
           direct or contingent, that is material to the Company and its
           subsidiaries considered as one enterprise, incurred by the Company or
           its subsidiaries, except obligations incurred in the ordinary course
           of business, (d) any change in the capital stock or outstanding

           paid or made on the capital stock of the Company or any of its
           subsidiaries, or (f) any loss or damage (whether or not insured) to
           the property of the Company or any of its subsidiaries which has been
           sustained or will have been sustained which has a material adverse
           effect on the condition (financial or otherwise), earnings,
           operations, business or business prospects of the Company and its
           subsidiaries considered as one enterprise.

           (h)   You shall be satisfied that, and you shall have received a
certificate, dated the Closing Date, or any later date on which Option Shares
are to be purchased, as the case may be, from the Attorneys for each Selling
Stockholder to the effect that, as of the Closing Date, or any later date on
which Option Shares are to be purchased, as the case may be, they have not been
informed that:

                 (i)   The representations and warranties made by such Selling
           Stockholder herein are not true or correct in any material respect on
           the Closing Date or on any later date on which Option Shares are to
           be purchased, as the case may be; or

                 (ii)  Such Selling Stockholder has not complied with any
           obligation or satisfied any condition which is required to be
           performed or satisfied on the part of such Selling Stockholder at or

hereafter acquires the power of disposition, otherwise than (i) as a bona fide
gift or gifts, provided the donee or donees thereof agree in writing to be bound
by this restriction, (ii) as a distribution to partners or shareholders of such
person, provided that the distributees thereof agree in writing to be bound by

Robertson, Stephens & Company LLC. The foregoing restriction shall have been
expressly agreed to preclude the holder of the Securities from engaging in any
hedging or other transaction which is designed to or reasonably expected to lead
to or result in a Disposition of Securities during the Lock-up Period, even if
such Securities would be disposed of by someone other than the such holder. Such
prohibited hedging or other transactions would including, without limitation,

(other than a broad-based market basket or index) that includes, relates to or
derives any significant part of its value from Securities. Furthermore, such
person will have also agreed and consented to the entry of stop transfer
instructions with the Company's transfer agent against the transfer of the
Securities held by such person except in compliance with this restriction.

           (j)   The Company and the Selling Stockholders shall have furnished
to you such further certificates and documents as you shall reasonably request

Company and the Selling Stockholders herein, as to the performance by the
Company and the Selling Stockholders of their respective obligations hereunder
and as to the other conditions concurrent and precedent to the obligations of
the Underwriters hereunder.

           All such opinions, certificates, letters and documents will be in
compliance with the provisions hereof only if they are reasonably satisfactory
to Underwriters' Counsel. The Company and the Selling Stockholders will furnish
you with such number of conformed copies of such opinions, certificates, letters
and documents as you shall reasonably request.

     8.    Option Shares.
           -------------

           (a)   On the basis of the representations, warranties and agreements
herein contained, but subject to the terms and conditions herein set forth,
certain of the Selling Stockholders hereby grants to the several Underwriters,
for the purpose of covering over-allotments in connection with the distribution
and sale of the Firm Shares only, a nontransferable option to purchase up to an
aggregate of ________ Option Shares at the purchase price per share for the Firm
Shares set forth in Section 4 hereof. Such option may be exercised by the
Representatives on behalf of the several Underwriters on one (1) or more
occasions in whole or in part during the period of thirty (30) days after the
date on which the Firm Shares are initially offered to the public, by giving
written notice to the Attorneys. The number of Option Shares to be purchased by
each Underwriter upon the exercise of such option shall be the same proportion
of the total number of Option Shares to be purchased by the several Underwriters
pursuant to the exercise of such option as the number of Firm Shares purchased
by such Underwriter (set forth in Schedule A hereto) bears to the total number
of Firm Shares purchased by the several Underwriters (set forth in Schedule A
hereto), adjusted by the Representatives in such manner as to avoid fractional
shares.

           Delivery of definitive certificates for the Option Shares to be
purchased by the several Underwriters pursuant to the exercise of the option
granted by this Section 8 shall be made against payment of the purchase price
therefor by the several Underwriters by certified or official bank check or
checks drawn in next-day funds, payable to the order of the Attorneys (and the
Attorneys agree not to deposit any such check in the bank on which it is drawn,
and not to take any other action with the purpose or effect of receiving
immediately available funds, until the business day following the date of its
delivery to the Attorneys). In the event of any breach of the foregoing, the
Selling Stockholders who propose to sell the Option Shares shall reimburse the
Underwriters for the interest lost and any other expenses borne by them by
reason of such breach. Such delivery and payment shall take place at the offices
of Testa, Hurwitz & Thibeault, LLP, High Street Tower, 
<PAGE>
 
                                     -30-

125 High Street, Boston, MA 02110 or at such other place as may be agreed upon
among the Representatives and the Attorneys (i) on the Closing Date, if written
notice of the exercise of such option is received by the Attorneys at least two
(2) full business days prior to the Closing Date, or (ii) on a date which shall
not be later than the third (3rd) full business day following the date the
Attorneys receive written notice of the exercise of such option, if such notice
is received by the Attorneys less than two (2) full business days prior to the
Closing Date.

           The certificates for the Option Shares to be so delivered will be
made available to you at such office or such other location including, without
limitation, in New York City, as you may reasonably request for checking at
least one (1) full business day prior to the date of payment and delivery and
will be in such names and denominations as you may request, such request to be
made at least two (2) full business days prior to such date of payment and
delivery. If the Representatives so elect, delivery of the Option Shares may be
made by credit through full fast transfer to the accounts at The Depository
Trust Company designated by the Representatives.

           It is understood that you, individually, and not as the
Representatives of the several Underwriters, may (but shall not be obligated to)
make payment of the purchase price on behalf of any Underwriter or Underwriters
whose check or checks shall not have been received by you prior to the date of
payment and delivery for the Option Shares to be purchased by such Underwriter
or Underwriters. Any such payment by you shall not relieve any such Underwriter
or Underwriters of any of its or their obligations hereunder.

           (b)   Upon exercise of any option provided for in Section 8(a)
hereof, the obligations of the several Underwriters to purchase such Option
Shares will be subject (as of the date hereof and as of the date of payment and
delivery for such Option Shares) to the accuracy of and compliance with the
representations, warranties and agreements of the Company and the Selling
Stockholders selling Option Shares herein, to the accuracy of the statements of
the Company, the Selling Stockholders selling Option Shares and officers of the
Company made pursuant to the provisions hereof, to the performance by the
Company and the Selling Stockholders selling Option Shares of their respective
obligations hereunder, to the conditions set forth in Section 7 hereof, and to
the condition that all proceedings taken at or prior to the payment date in
connection with the sale and transfer of such Option Shares shall be
satisfactory in form and substance to you and to Underwriters' Counsel, and you
shall have been furnished with all such documents, certificates and opinions as
you may request in order to evidence the accuracy and completeness of any of the
representations, warranties or statements, the performance of any of the
covenants or agreements of the Company and the Selling Stockholders selling
Option Shares or the satisfaction of any of the conditions herein contained.

     9.    Indemnification and Contribution.
           --------------------------------

           (a)   The Company agrees to indemnify and hold harmless each
Underwriter against any losses, claims, damages or liabilities, joint or
several, to which such Underwriter may become subject (including, without

including, but not limited to, losses, claims, damages or liabilities (or
actions in respect thereof) arising out of or based upon (i) any breach of any
representation, warranty, agreement or covenant of the Company herein contained,
(ii) any untrue statement or alleged untrue statement of any material fact
contained in the Registration Statement or any amendment or supplement thereto,
or the omission or alleged omission to state therein a material fact required to
be stated therein or necessary to make the statements therein not misleading, or
(iii) any untrue statement or alleged untrue statement of any material fact
contained in any Preliminary Prospectus or the Prospectus or any amendment or
supplement thereto, or the omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements
therein, in the light of the circumstances under which they were made, not
misleading, and agrees to reimburse each Underwriter for any legal or other
expenses reasonably incurred by it in connection with investigating or defending
any such loss, claim, damage, liability or action; provided, however, that the
                                                   --------  -------
Company shall not be liable in any such case to the extent that any such loss,
claim, damage, liability or action arises out of or is based upon an untrue
statement or alleged untrue statement or omission or alleged omission made in
the Registration Statement, such Preliminary Prospectus or the Prospectus, or
any such amendment or supplement thereto, in reliance upon, and in conformity
with, written information relating to any Underwriter furnished to the Company
by such Underwriter, directly or through you, specifically for use in the
preparation thereof and, provided further, that the indemnity agreement provided
                         -------- -------
in this Section 9(a) with respect to any Preliminary Prospectus shall not inure
to the benefit of any Underwriter from whom the person asserting any losses,
claims, damages, liabilities or actions based upon any untrue statement or
alleged untrue statement of material fact or omission or alleged omission to
state therein a material fact purchased Shares, if a copy of the Prospectus in
which such untrue statement or alleged untrue statement or omission or alleged
omission was corrected had not been sent or given to such person within the time
required by the Act and the Rules and Regulations, unless such failure is the
result of noncompliance by the Company with Section 5(d) hereof.

           The indemnity agreement in this Section 9(a) shall extend upon the 
same terms and conditions to, and shall inure to the benefit of, each person, if
any, who controls any Underwriter within the meaning of the Act or the Exchange
Act. This indemnity agreement shall be in addition to any liabilities which the
Company may otherwise have.

           (b) Each Selling Stockholder, severally and not jointly, agrees to
indemnify and hold harmless each Underwriter against any losses, claims, damages
or liabilities, joint or several, to which such Underwriter may become subject
(including, without limitation, in its capacity as an Underwriter or as a
"qualified independent underwriter" within the meaning of Schedule E or the
Bylaws of the NASD) under the Act, the Exchange Act or otherwise, specifically
including, but not limited to, losses, claims, damages or liabilities (or
actions in respect thereof) arising out of or based upon (i) any breach of any
representation, warranty, agreement or covenant of such Selling Stockholder
herein contained, (ii) any untrue statement or alleged untrue statement of any
material fact contained in the Registration Statement or any amendment or
supplement thereto, or the omission or alleged omission to state therein a
<PAGE>
 
                                     -32-

material fact required to be stated therein or necessary to make the statements
therein not misleading, or (iii) any untrue statement or alleged untrue
statement of any material fact contained in any Preliminary Prospectus or the
Prospectus or any amendment or supplement thereto, or the omission or alleged
omission to state therein a material fact necessary to make the statements
therein, in the light of the circumstances under which they were made, not
misleading, in the case of subparagraphs (ii) and (iii) of this Section 9(b) to
the extent, but only to the extent, that such untrue statement or alleged untrue
statement or omission or alleged omission was made in reliance upon and in
conformity with written information furnished to the Company or such Underwriter
by such Selling Shareholder, directly or through such Selling Stockholder's
representatives, specifically for use in the preparation thereof, and agrees to
reimburse each Underwriter for any legal or other expenses reasonably incurred
by it in connection with investigating or defending any such loss, claim,
damage, liability or action; provided, however, that the indemnity agreement
                             --------  -------
provided in this Section 9(b) with respect to any Preliminary Prospectus shall
not inure to the benefit of any Underwriter from whom the person asserting any
losses, claims, damages, liabilities or actions based upon any untrue statement
or alleged untrue statement of a material fact or omission or alleged omission
to state therein a material fact purchased Shares, if a copy of the Prospectus
in which such untrue statement or alleged untrue statement or omission or
alleged omission was corrected had not been sent or given to such person within
the time required by the Act and the Rules and Regulations, unless such failure
is the result of noncompliance by the Company with Section 5(d) hereof.

           The indemnity agreement in this Section 9(b) shall extend upon the 
same terms and conditions to, and shall inure to the benefit of, each person, if
any, who controls any Underwriter within the meaning of the Act or the Exchange
Act. This indemnity agreement shall be in addition to any liabilities which such
Selling Stockholder may otherwise have.

           (c) Each Underwriter, severally and not jointly, agrees to 
indemnify and hold harmless the Company and each Selling Stockholder against any
losses, claims, damages or liabilities, joint or several, to which the Company
or such Selling Stockholder may become subject under the Act or otherwise,
specifically including, but not limited to, losses, claims, damages or
liabilities (or actions in respect thereof) arising out of or based upon (i) any
breach of any representation, warranty, agreement or covenant of such
Underwriter herein contained, (ii) any untrue statement or alleged untrue
statement of any material fact contained in the Registration Statement or any
amendment or supplement thereto, or the omission or alleged omission to state
therein a material fact required to be stated therein or necessary to make the
statements therein not misleading, or (iii) any untrue statement or alleged
untrue statement of any material fact contained in any Preliminary Prospectus or
the Prospectus or any amendment or supplement thereto, or the omission or
alleged omission to state therein a material fact necessary to make the
statements therein, in the light of the circumstances under which they were
made, not misleading, in the case of subparagraphs (ii) and (iii) of this
Section 9(c) to the extent, but only to the extent, that such untrue statement
or alleged untrue statement or omission or alleged omission was made in reliance
upon and in conformity with written information furnished to the Company by such
Underwriter, directly or through you, specifically for use in the preparation
thereof, and agrees to reimburse the Company and each such Selling Stockholder
for any legal or other expenses reasonably incurred by the Company and each such
Selling Stockholder in connection with investigating or defending any such loss,
claim, damage, liability or action.
<PAGE>
 
                                     -33-

           The indemnity agreement in this Section 9(c) shall extend upon the 
same terms and conditions to, and shall inure to the benefit of, each officer of
the Company who signed the Registration Statement and each director of the
Company, each Selling Stockholder and each person, if any, who controls the
Company or any Selling Stockholder within the meaning of the Act or the Exchange
Act. This indemnity agreement shall be in addition to any liabilities which each
Underwriter may otherwise have.

           (d) Promptly after receipt by an indemnified party under this 
Section 9 of notice of the commencement of any action, such indemnified party
shall, if a claim in respect thereof is to be made against any indemnifying
party under this Section 9, notify the indemnifying party in writing of the
commencement thereof but the omission so to notify the indemnifying party will
not relieve it from any liability which it may have to any indemnified party
otherwise than under this Section 9. In case any such action is brought against
any indemnified party, and it notified the indemnifying party of the
commencement thereof, the indemnifying party will be entitled to participate
therein and, to the extent that it shall elect by written notice delivered to
the indemnified party promptly after receiving the aforesaid notice from such
indemnified party, to assume the defense thereof, with counsel reasonably
satisfactory to such indemnified party; provided, however, that if the
                                        --------  -------
defendants in any such action include both the indemnified party and the
indemnifying party and the indemnified party shall have reasonably concluded
that there may be legal defenses available to it and/or other indemnified
parties which are different from or additional to those available to the
indemnifying party, the indemnified party or parties shall have the right to
select separate counsel to assume such legal defenses and to otherwise
participate in the defense of such action on behalf of such indemnified party or
parties. Upon receipt of notice from the indemnifying party to such indemnified
party of the indemnifying party's election so to assume the defense of such
action and approval by the indemnified party of counsel, the indemnifying party
will not be liable to such indemnified party under this Section 9 for any legal
or other expenses subsequently incurred by such indemnified party in connection
with the defense thereof unless (i) the indemnified party shall have employed
separate counsel in accordance with the proviso to the next preceding sentence
(it being understood, however, that the indemnifying party shall not be liable
for the expenses of more than one separate counsel (together with appropriate
local counsel) approved by the indemnifying party representing all the
indemnified parties under Section 9(a), 9(b) or 9(c) hereof who are parties to
such action), (ii) the indemnifying party shall not have employed counsel
satisfactory to the indemnified party to represent the indemnified party within
a reasonable time after notice of commencement of the action or (iii) the
indemnifying party has authorized the employment of counsel for the indemnified
party at the expense of the indemnifying party. In no event shall any
indemnifying party be liable in respect of any amounts paid in settlement of any
action unless the indemnifying party shall have approved the terms of such
settlement; provided that such consent shall not be unreasonably withheld. No
            --------
indemnifying party shall, without the prior written consent of the indemnified
party, effect any settlement of any pending or threatened proceeding in respect
of which any indemnified party is or could have been a party and indemnification
could have been sought hereunder by such indemnified party, unless such
settlement includes an unconditional release of such indemnified party from all
liability on all claims that are the subject matter of such proceeding.
<PAGE>
 
                                     -34-

           (e)   In order to provide for just and equitable contribution in 
any action in which a claim for indemnification is made pursuant to this Section
9 but it is judicially determined (by the entry of a final judgment or decree by
a court of competent jurisdiction and the expiration of time to appeal or the
denial of the last right of appeal) that such indemnification may not be
enforced in such case notwithstanding the fact that this Section 9 provides for
indemnification in such case, all the parties hereto shall contribute to the
aggregate losses, claims, damages or liabilities to which they may be subject
(after contribution from others) in such proportion so that the Underwriters
severally and not jointly are responsible pro rata for the portion represented
by the percentage that the underwriting discount bears to the initial public
offering price, and the Company and the Selling Stockholders are responsible for
the remaining portion, provided, however, that (i) no Underwriter shall be
                       --------  -------
required to contribute any amount in excess of the amount by which the
underwriting discount applicable to the Shares purchased by such Underwriter
exceeds the amount of damages which such Underwriter has otherwise required to
pay and (ii) no person guilty of a fraudulent misrepresentation (within the
meaning of Section 11(f) of the Act) shall be entitled to contribution from any
person who is not guilty of such fraudulent misrepresentation. The contribution
agreement in this Section 9(e) shall extend upon the same terms and conditions
to, and shall inure to the benefit of, each person, if any, who controls any
Underwriter, the Company or any Selling Stockholder within the meaning of the
Act or the Exchange Act and each officer of the Company who signed the
Registration Statement and each director of the Company.

           (f)   The liability of each Selling Stockholder under the 
representations, warranties and agreements contained herein and under the
indemnity agreements contained in the provisions of this Section 9 shall be
limited to an amount equal to the initial public offering price of the Selling
Stockholder Shares sold by such Selling Stockholder to the Underwriters minus
the amount of the underwriting discount paid thereon to the Underwriters by such
Selling Stockholder. The Company and such Selling Stockholders may agree, as
among themselves and without limiting the rights of the Underwriters under this
Agreement, as to the respective amounts of such liability for which they each
shall be responsible.

           (g)   The parties to this Agreement hereby acknowledge that they are
sophisticated business persons who were represented by counsel during the
negotiations regarding the provisions hereof including, without limitation, the
provisions of this Section 9, and are fully informed regarding said provisions.
They further acknowledge that the provisions of this Section 9 fairly allocate
the risks in light of the ability of the parties to investigate the Company and
its business in order to assure that adequate disclosure is made in the
Registration Statement and Prospectus as required by the Act and the Exchange
Act.

     10.   Representations, Warranties, Covenants and Agreements to Survive 
           ----------------------------------------------------------------
Delivery. All representations, warranties, covenants and agreements of the 
- ---------
Company, the Selling Stockholders and the Underwriters herein or in certificates
delivered pursuant hereto, and the indemnity and contribution agreements
contained in Section 9 hereof shall remain operative and in full force and
effect regardless of any investigation made by or on behalf of any Underwriter
or any person controlling any Underwriter within the meaning of the Act or the
Exchange Act, or by or on behalf of the Company or any Selling Stockholder, or
any of their officers, directors or controlling persons
<PAGE>
 
                                     -35-

within the meaning of the Act or the Exchange Act, and shall survive the
delivery of the Shares to the several Underwriters hereunder or termination of
this Agreement.

     11.   Substitution of Underwriters. If any Underwriter or Underwriters
           ----------------------------
shall fail to take up and pay for the number of Firm Shares agreed by such
Underwriter or Underwriters to be purchased hereunder upon tender of such Firm
Shares in accordance with the terms hereof, and if the aggregate number of Firm
Shares which such defaulting Underwriter or Underwriters so agreed but failed to
purchase does not exceed 10% of the Firm Shares, the remaining Underwriters
shall be obligated, severally in proportion to their respective commitments
hereunder, to take up and pay for the Firm Shares of such defaulting Underwriter
or Underwriters.

           If any Underwriter or Underwriters so defaults and the aggregate 
number of Firm Shares which such defaulting Underwriter or Underwriters agreed
but failed to take up and pay for exceeds 10% of the Firm Shares, the remaining
Underwriters shall have the right, but shall not be obligated, to take up and
pay for (in such proportions as may be agreed upon among them) the Firm Shares
which the defaulting Underwriter or Underwriters so agreed but failed to
purchase. If such remaining Underwriters do not, at the Closing Date, take up
and pay for the Firm Shares which the defaulting Underwriter or Underwriters so
agreed but failed to purchase, the Closing Date shall be postponed for twenty-
four (24) hours to allow the several Underwriters the privilege of substituting
within twenty-four (24) hours (including non-business hours) another underwriter
or underwriters (which may include any nondefaulting Underwriter) satisfactory
to the Company. If no such underwriter or underwriters shall have been
substituted as aforesaid by such postponed Closing Date, the Closing Date may,
at the option of the Company, be postponed for a further twenty-four (24) hours,
if necessary, to allow the Company the privilege of finding another underwriter
or underwriters, satisfactory to you, to purchase the Firm Shares which the
defaulting Underwriter or Underwriters so agreed but failed to purchase. If it
shall be arranged for the remaining Underwriters or substituted underwriter or
underwriters to take up the Firm Shares of the defaulting Underwriter or
Underwriters as provided in this Section 11, (i) the Company shall have the
right to postpone the time of delivery for a period of not more than seven (7)
full business days, in order to effect whatever changes may thereby be made
necessary in the Registration Statement or the Prospectus, or in any other
documents or arrangements, and the Company agrees promptly to file any
amendments to the Registration Statement, supplements to the Prospectus or other
such documents which may thereby be made necessary, and (ii) the respective
number of Firm Shares to be purchased by the remaining Underwriters and
substituted underwriter or underwriters shall be taken as the basis of their
underwriting obligation. If the remaining Underwriters shall not take up and pay
for all such Firm Shares so agreed to be purchased by the defaulting Underwriter
or Underwriters or substitute another underwriter or underwriters as aforesaid
and the Company shall not find or shall not elect to seek another underwriter or
underwriters for such Firm Shares as aforesaid, then this Agreement shall
terminate.

     In the event of any termination of this Agreement pursuant to the preceding
paragraph of this Section 11, neither the Company nor any Selling Stockholder
shall be liable to any Underwriter (except as provided in Sections 6 and 9
hereof) nor shall any Underwriter (other than an Underwriter who shall have
failed, otherwise than for some reason permitted under this Agreement, to
purchase the number of Firm Shares agreed by such Underwriter to be purchased
<PAGE>
 
                                      -36-



hereunder, which Underwriter shall remain liable to the Company, the Selling
Stockholders and the other Underwriters for damages, if any, resulting from such
default) be liable to the Company or any Selling Stockholder (except to the
extent provided in Sections 6 and 9 hereof).

          The term "Underwriter" in this Agreement shall include any
person substituted for an Underwriter under this
Section 11.

     12.  Effective Date of this Agreement and Termination.
          ------------------------------------------------

          (a) This Agreement shall become effective at the earlier of (i) 6:30
A.M., San Francisco time, on the first full business day following the effective
date of the Registration Statement, or (ii) the time of the initial public
offering of any of the Shares by the Underwriters after the Registration
Statement becomes effective. The time of the initial public offering shall mean
the time of the release by you, for publication, of the first newspaper
advertisement relating to the Shares, or the time at which the Shares are first
generally offered by the Underwriters to the public by letter, telephone,
telegram or telecopy, whichever shall first occur. By giving notice as set forth
in Section 13 before the time this Agreement becomes effective, you, as
Representatives of the several Underwriters, or the Company, may prevent this
Agreement from becoming effective without liability of any party to any other
party, except as provided in Sections 5(j), 6 and 9 hereof.

          (b) You, as Representatives of the several Underwriters, shall have
the right to terminate this Agreement by giving notice as hereinafter specified
at any time on or prior to the Closing Date or on or prior to any later date on
which Option Shares are to be purchased, as the case may be, (i) if the Company
or any Selling Stockholder shall have failed, refused or been unable to perform
any agreement on its part to be performed, or because any other condition of the
Underwriters' obligations hereunder required to be fulfilled is not fulfilled,
including, without limitation, any change in the condition (financial or
otherwise), earnings, operations, business or business prospects of the Company
and its subsidiaries considered as one enterprise from that set forth in the
Registration Statement or Prospectus, which, in your sole judgment, is material
and adverse, or (ii) if additional material governmental restrictions, not in
force and effect on the date hereof, shall have been imposed upon trading in
securities generally or minimum or maximum prices shall have been generally
established on the New York Stock Exchange or on the American Stock Exchange or
in the over the counter market by the NASD, or trading in securities generally
shall have been suspended on either such exchange or in the over the counter
market by the NASD, or if a banking moratorium shall have been declared by
federal, New York or California authorities, or (iii) if the Company shall have
sustained a loss by strike, fire, flood, earthquake, accident or other calamity
of such character as to interfere materially with the conduct of the business
and operations of the Company regardless of whether or not such loss shall have
been insured, or (iv) if there shall have been a material adverse change in the
general political or economic conditions or financial markets as in your
reasonable judgment makes it inadvisable or impracticable to proceed with the
offering, sale and delivery of the Shares, or (v) if there shall have been an
outbreak or escalation of hostilities or of any other insurrection or armed
conflict or the declaration by the United States of a national emergency which,
in the reasonable opinion of the Representatives, makes it impracticable or
inadvisable to proceed with the public offering of the Shares as contemplated by
the Prospectus. In the event of termination pursuant to subparagraph (i) above,
the 
<PAGE>
 
                                      -37-

Company shall remain obligated to pay costs and expenses pursuant to Sections
5(j), 6 and 9 hereof. Any termination pursuant to any of subparagraphs (ii)
through (v) above shall be without liability of any party to any other party
except as provided in Sections 6 and 9 hereof.

          If you elect to prevent this Agreement from becoming effective or to
terminate this Agreement as provided in this Section 12, you shall promptly
notify the Company by telephone, telecopy or telegram, in each case confirmed by
letter. If the Company shall elect to prevent this Agreement from becoming
effective, the Company shall promptly notify you by telephone, telecopy or
telegram, in each case, confirmed by letter.

each share of Series C Stock and Series D Stock, payable semiannually on January

D Stock to the extent permitted by law. Any such dividend payments may be made,
at the option of the Corporation, in cash or by the issuance by the Corporation

Series B Stock at the rate of .12 of a share for each $1.6068 of such accrued
dividends on Series B Stock, Series C Stock at the rate of .12 of a share for

C Stock only if all holders of Series A Stock and Series B Stock receive their
dividend pursuant to Subparagraph 1(b) of this Certificate on such date
exclusively in shares of Series A Stock and Series B Stock, respectively; and
(iii) Series B Stock may be paid in shares of Series B Stock only if all the
holders of Series A Stock receive their dividend pursuant to Subparagraph 1(b)
of this Certificate on such date exclusively in shares of Series A Stock. The
issuance of such additional shares of Series A Stock, Series B Stock, Series C
Stock and/or Series D Stock, as the case may be, shall constitute full payment
of such dividends.

                        (c)     The holders of the Series E Stock shall be 
entitled to dividends when, as and if declared by the Board of Directors to the
extent permitted by law.  Such dividends will not be mandatory or cumulative.

                2.      Liquidation.  (a)  In the event of a voluntary or 
                        -----------
involuntary liquidation, dissolution or winding up of the Corporation or the 
sale, lease, conveyance or other disposition of all or substantially all of its
property and business, the holders of Series C Stock shall be entitled to 
receive $6.00 per share (subject to proportionate adjustments in the event of 
stock splits or other similar events), plus an amount equal to all declared 
and/or accrued and unpaid dividends, before any distribution or payment is made
to the holders of Series E Stock, Series D Stock, Series B Stock, Series A 
Stock or Common Stock.  If, upon any such sale, liquidation, dissolution or 
winding up of the Corporation, the assets distributable among the holders of 
all Series C Stock shall be insufficient to permit the payment in full to such
holders of the amount herein above and in this Certificate provided, then the 
entire assets of the Corporation shall be applied ratably to the payment of 
such amount to the holders of Series C Stock then outstanding pari passu on an 
                                                              ---- -----
as-if converted to Common Stock basis until the Series C Stockholders have 
received their full liquidation preference under this Section 2.

                        (b)     In the event of a voluntary or involuntary 
liquidation, dissolution or winding up of the Corporation or the sale, lease, 
conveyance or other disposition of all or substantially all of its property and
business, the holders of Series B Stock shall be entitled, subject to the 
rights of the Series C Stock as set forth above, to receive $13.39 per share 
(subject to 

                                       3
<PAGE>
 
proportionate adjustments in the event of stock splits or other similar events),
plus an amount equal to all declared and/or accrued and unpaid dividends, before
any distribution or payment is made to the holders of Series E Stock, Series D
Stock, Series A Stock or Common Stock. If, upon any such sale, liquidation,
dissolution or winding up of the Corporation, and after the payment in full of
all amounts to which the holders of Series C Stock are entitled as provided
above, the assets distributable among the holders of all Series B Stock shall be
insufficient to permit the payment in full to such holders of the amount herein
above and in this Certificate provided, then the entire remaining assets of the
Corporation shall be applied ratably to the payment of such amount to the
holders of Series B Stock then outstanding pari passu on an as-if converted to
                                           ---- ----
Common Stock basis until the Series B Stockholders have received their full
liquidation preference under this Section 2.

                        (c)     In the event of a voluntary or involuntary 
liquidation, dissolution or winding up of the Corporation or the sale, lease, 
conveyance or other disposition of all or substantially all of its property and
business, the holders of Series A Stock and Series D Stock shall be entitled, 
subject to the rights of the Series C Stock and Series B Stock as set forth in 
this Certificate, to receive $13.39 per share or $6.00 per share, respectively 
(subject to proportionate adjustments in the event of stock splits or other 
similar events), plus an amount equal to all declared and/or accrued and unpaid
dividends pari passu with the Series D Stock and Series A Stock, respectively, 
          ---- -----
before any distribution or payment is made to the holders of Series E Stock, 
Common Stock or any Junior Stock (as defined in paragraph 7 below).  If, upon 
any such sale, liquidation, dissolution or winding up of the Corporation, and 
after the payment in full of all amounts to which the holders of Series C Stock
and Series B Stock are entitled as provided above, the assets distributable 
among the holders of all Series D Stock and Series A Stock shall be insufficient
to permit the payment in full to such holders of the amount herein above and in
this Certificate provided, then the entire remaining assets of the Corporation 
shall be applied ratably, based on the relative liquidation preferences of the 
Series D Stock and Series A Stock, to the payment of such amount to the holders
of Series D Stock and Series A Stock then outstanding until the Series D 
Stockholders and Series A Stockholders have received their full liquidation 
preferences under this Section 2.

                        (d)     In the event of a voluntary or involuntary 
liquidation, dissolution or winding up of the Corporation or the sale, lease, 
conveyance or other disposition of all or substantially all of its property and
business, the holders of Series E Stock shall be entitled, subject to the 
rights of the Series D Stock, Series C Stock, Series B Stock and Series A Stock
as set forth in this Certificate, to receive $20.00 per share (subject to 
proportionate adjustments in the event of stock splits or other similar 
events), plus an amount equal to all declared and unpaid dividends, before any 
distribution or payment is made to the holders of Common Stock or any Junior 
Stock (as defined in paragraph 7 below).  If upon any such sale, liquidation, 
dissolution or winding up of the Corporation, and after the payment in full of 
all amounts to which the holders of the Series D Stock, Series C Stock, Series 
B Stock and Series A Stock are entitled above, the assets distributable among 
the holders of all Series E Stock shall be insufficient to permit the payment 
in full to such holders of the amount herein above and in this Certificate 
provided, then the entire remaining assets of the Corporation shall be applied 
ratably to the payment of such amount to the holders of Series E Stock then 
outstanding pari passu on an as-if converted to Common Stock basis until the 
Series E Stockholders have received their full liquidation preference.

conveyance or other disposition of all or substantially all of its property and
business, and subject to the rights of the Series E Stock, Series D Stock, 
Series C Stock, Series B Stock and Series A Stock as set forth above, after 
payment of the foregoing liquidation preferences to the holders of the Series E
Stock, Series D Stock, Series C Stock, Series B Stock and Series A Stock, all 
remaining assets of the Corporation shall be distributed ratably among the 
holders of the Corporation's Common Stock.

                        (f)     Neither the merger nor the consolidation of the
Corporation, nor the sale, lease or conveyance of all or part of its property 
and business as an entirety, shall be deemed to be a liquidation, dissolution 
or winding up of the Corporation within the meaning of this paragraph 2, unless
such sale, lease or conveyance shall be in connection with a plan of 
liquidation, dissolution or winding up of the Corporation.

                3.      Redemption.  (a)  The shares of Series A Stock, Series B
                        ----------
Stock, Series C Stock and Series D Stock at the time outstanding may be 
redeemed, in whole only and not in part, and only if all of the shares of 
Series A Stock, Series B Stock, Series C Stock and Series D Stock are redeemed 
pursuant to Section 3 of this Certificate, by the Corporation at its option 
expressed by a resolution adopted by its Board of Directors, at any time on and
after June 30, 1997, at a price equal to the sum of $13.39 per share of Series 
A Stock and Series B Stock and $6.00 per share of Series C Stock and Series D
Stock (subject to proportionate adjustments in the event of stock splits or 
other similar events), plus an amount equal to all declared and/or accrued and 
unpaid dividends thereon to the date fixed for redemption (the "Redemption 
Price").

                        (b)     If, pursuant to subparagraph 3(a) above, the 
Corporation shall redeem shares of Series A Stock, Series B Stock, Series C 
Stock and Series D Stock, the Corporation shall give written notice of such 
redemption to each holder of record of shares of Series A Stock, Series B 
Stock, Series C Stock and Series D Stock to be redeemed not less than 30 nor 
more than 60 days prior to the date fixed for redemption, by certified mail 
enclosed in a postage paid envelope addressed to such holder at such holder's 
address as the same shall appear on the books of the Corporation.  Such notice 
shall (i) state that the Corporation has elected to redeem such shares, (ii) 
state the date fixed for redemption, (iii) state the Redemption Price, (iv) 
state that the shares called for redemption are convertible until the close of 
business on the second day preceding the date fixed for redemption and (v) call
upon such holder to surrender to the Corporation on or after said date at its 
principal place of business designated in such notice, a certificate or 
certificates representing the number of shares of Series A Stock, Series B 
Stock, Series C Stock and Series D Stock to be redeemed in accordance with such
notice.  On or after the date fixed in such notice for redemption, each holder 
of shares of Series A Stock, Series B Stock, Series C Stock and Series D Stock 
to be so redeemed shall present and surrender the certificate or certificates 
for such shares to the Corporation at the place designated in said notice and 
thereupon the Redemption Price of such shares shall be paid to, or to the order
of, the person whose name appears on such certificate or certificates as the 
owner thereof.  From and after the date fixed in any such notice as the date 
for redemption, unless default shall be made by the Corporation in providing 
for the payment of the Redemption Price pursuant to such notice, all rights of 
the holders of the Series A Stock, Series B Stock, Series C Stock and Series D 
Stock so redeemed, except the right to receive the Redemption Price (but 
without interest thereon) shall cease and terminate; provided, however, that on
or before 

                                       5
<PAGE>
 
the date fixed for redemption in such notice, the Corporation shall deposit with
a bank or trust company having a capital stock and surplus of at least
$500,000,000 in trust to be applied to the redemption of the Series A Stock,
Series B Stock, Series C Stock and Series D Stock so called for redemption, an
amount sufficient to redeem the Series A Stock, Series B Stock, Series C Stock
and Series D Stock called for redemption. Any moneys so deposited which relate
to Series A Stock, Series B Stock, Series C Stock and Series D Stock called for
redemption which prior to redemption are converted into Common Stock as provided
herein shall be promptly repaid to the Corporation. Any moneys so deposited for
Series A Stock, Series B Stock, Series C Stock and Series D Stock which remain
unclaimed at the end of one year from the date of such deposit shall be repaid
to the Corporation, but the Corporation shall remain obligated to make payment
thereof to the holders of such Series A Stock, Series B Stock, Series C Stock
and Series D Stock entitled thereto (subject to any applicable escheat or
similar laws).

                        (c)     Any shares of Series A Stock, Series B Stock, 
Series C Stock and Series D Stock redeemed by the Corporation shall be retired 
and shall not be reissued and the Corporation may, from time to time, take such
appropriate corporate action as may be necessary to reduce the number of 
authorized shares of Series A Stock, Series B Stock, Series C Stock and Series 
D Stock.

                        (d)     The Series E Stock is not redeemable.

                4.      Conversion.  (a)  The holder of any share or shares of 
                        ----------
Series A Stock, Series B Stock, Series C, Series D Stock or Series E Stock 
shall have the right, at such holder's option, to convert all or any portion of
such shares into one fully paid and nonassessable share of Common Stock for each
share of Series A Stock, Series B Stock, Series C Stock, Series D Stock or 
Series E Stock or at the rate which results from the making of any adjustment 
specified in subparagraph 4(g) hereof, if applicable (the number of shares of 
Common Stock issuable at any time, giving effect to the latest prior adjustment
pursuant to subparagraph 4(g) hereof, if any and if applicable, in exchange for
one share of Series A Stock, Series B Stock, Series C Stock, Series D Stock or 
Series E Stock being hereinafter called the "Conversion Rate").  To the extent 
permitted by law, when shares of Series A Stock, Series B Stock, Series C Stock,
Series D Stock or Series E Stock are converted, all dividends declared or 
accrued, as applicable, and unpaid on the stock so converted to the date of 
conversion (whether or not currently payable) shall be immediately due and 
payable in cash or in shares of Series A Stock at the rate of .12 of a share for
each $1.6068 of such dividend on Series A Stock, shares of Series B Stock at the
rate of .12 of a share for each $1.6068 of such dividend on Series B Stock, 
shares of Series C Stock at the rate of .12 of a share for each $0.72 of such 
dividend on Series C Stock and shares of Series D Stock at the rate of .12 of a
share for each $0.72 of such dividend on Series D Stock and shares of Series E 
Stock at the rate determined in good faith by the Company's Board of Directors 
and must accompany the shares of Common Stock issued upon such conversion.

                        (b)     The Series A Stock, Series B Stock, Series C 
Stock, Series D Stock or Series E Stock shall be convertible at the principal 
office of the Corporation into fully paid and nonassessable shares of Common 
Stock at the Conversion Rate.  In case of the redemption, pursuant to 
subparagraph 3(a) above, of any shares of Series A Stock, Series B Stock, Series
C Stock or Series D Stock, such right of conversion shall cease and terminate, 
as to the shares to be 

                                       6
<PAGE>
 
redeemed, at the close of business on the second day preceding the date fixed
for such redemption, unless default shall be made in the payment of the
Redemption Price for the shares to be so redeemed.

                        (c)     In order to convert shares of Series A Stock, 
Series B Stock, Series C Stock, Series D Stock or Series E Stock into shares of
Common Stock pursuant to the right of conversion set forth in subparagraph 4(a)
above, the holder thereof shall surrender the certificate or certificates 
representing such shares of Series A Stock, Series B Stock, Series C Stock, 
Series D Stock or Series E Stock duly endorsed to the Corporation or in blank, 
at the principal office of the Corporation and shall give written notice to the
Corporation that such holder elects to convert the same, stating in such notice
the name or names in which holder wishes the certificate or certificates 
representing shares of Common Stock to be issued.  The Corporation shall, 
within five (5) business days, deliver at said office or other place to such 
holder of Series A Stock, Series B Stock, Series C Stock, Series D Stock or 
Series E Stock, or to such holder's nominee or nominees, a certificate or 
certificates for the number of shares of Common Stock to which such holder 
shall be entitled as aforesaid, together with any cash to which such holder 
shall be entitled in lieu of fractional shares in an amount equal to the same 
fraction of the Conversion Amount (as defined in paragraph 7 below) of a whole 
share of Common Stock on the business day preceding the day of conversion.  
Shares of Series A Stock, Series B Stock, Series C Stock, Series D Stock or 
Series E Stock shall be deemed to have been converted as of the date of the 
surrender of such shares for conversion as provided above, and the person or 
persons entitled to receive the shares of Common Stock issuable upon such 
conversion shall be treated for all purposes as the record holder or holders of
such shares of Common Stock on such date.  Upon conversion of only a portion of
the number of shares covered by a certificate representing shares of Series A 
Stock, Series B Stock, Series C Stock, Series D Stock or Series E Stock 
surrendered for conversion, at the expense of the Corporation, a new 
certificate covering the number of shares of Series A Stock, Series B Stock, 
Series C Stock, Series D Stock or Series E Stock representing the unconverted 
portion of the certificate so surrendered, which new certificate shall entitle 
the holder thereof to the rights of the shares of Series A Stock, Series B 
Stock, Series C Stock, Series D Stock or Series E Stock represented thereby to 
the same extent as if the certificate theretofore covering such unconverted 
shares had not been surrendered for conversion.

                        (d)     Notwithstanding the provisions of subparagraph 
4(a) hereof, the issued and outstanding shares of Series A Stock, Series B 
Stock, Series C Stock, Series D Stock and Series E Stock shall be automatically
converted into fully paid and nonassessable shares of Common Stock at the 
Conversion Rate immediately upon the consummation of the Corporation's sale of 
Common Stock in a bona fide firm commitment underwriting pursuant to a 
registration statement filed with, and declared effective by, the Securities 
and Exchange Commission pursuant to the Securities Act of 1933, as amended, at 
a public offering price of not less than $32.50 per share (subject to 
proportionate adjustments to reflect stock splits or similar events) or such 
lesser amount as may be agreed to in writing by holders of at least a majority 
of the outstanding shares of Preferred Stock which results in aggregate gross 
cash proceeds to the Corporation of at least $10,000,000.

                        (e)     At least ten (10) days prior to the closing of 
a sale of Common Stock which meets the requirements of subparagraph (d), the 
Corporation shall give written notice to 

                                       7
<PAGE>
 
each holder of record of shares of Series A Stock, Series B Stock, Series C
Stock, Series D Stock and Series E Stock, by certified mail enclosed in a
postage paid envelope addressed to such holder at such holder's address as the
same shall appear on the books of the Corporation. Such notice shall (i) state
that the shares are being automatically converted pursuant to subparagraph (d)
hereof, (ii) state the expected date of conversion and (iii) call upon such
holder to exchange on or after such date at the principal place of business of
the Corporation a certificate or certificates representing the number of shares
of Series A Stock, Series B Stock, Series C Stock, Series D Stock or Series E
Stock to be converted in accordance with such notice. On or after such date, the
holder of Series A Stock, Series B Stock, Series C Stock, Series D Stock or
Series E Stock shall present and surrender the certificate or certificates for
the shares of Series A Stock, Series B Stock, Series C Stock, Series D Stock or
Series E Stock to the Corporation at the place designated in such notice, and
thereupon the Corporation shall deliver to such holder, or to such holder's
nominee or nominees, a certificate or certificates for the number of shares of
Common Stock to which such holder shall be entitled as aforesaid. Shares of
Series A Stock, Series B Stock, Series C Stock, Series D Stock and Series E
Stock shall be deemed to have been converted and canceled on such conversion
date and the person or persons entitled to receive the shares of Common Stock
issuable upon such automatic conversion shall be treated for all purposes as the
record holder or holders of such shares of Common Stock on the conversion date.
In the case of automatic conversion pursuant to subparagraph 4(d) hereof, the
Corporation shall not be obligated to issue certificates for shares of Common
Stock unless certificates evidencing the converted shares of Series A Stock,
Series B Stock, Series C Stock, Series D Stock or Series E Stock, as the case
may be, are delivered to the Corporation.

                        (f)     The issuance of certificates for shares of 
Common Stock upon the conversion of shares of Series A Stock, Series B Stock, 
Series C Stock, Series D Stock and Series E Stock shall be made without charge 
to the converting stockholder for any original issue or transfer tax in respect
of the issuance of such certificates and any such tax shall be paid by the 
Corporation.

                        (g)     The Conversion Rate shall be subject to the 
following adjustments:

                        (i)     If the Corporation shall declare and pay to the 
holders of Common Stock a dividend or other distribution payable in shares of 
Common Stock, the Conversion Rate in effect immediately prior thereto shall be 
adjusted so that the holders of Series A Stock, Series B Stock, Series C Stock,
Series D Stock and Series E Stock thereafter surrendered for conversion shall 
be entitled to receive the number of shares of Common Stock which such holder 
would have owned or been entitled to receive after the declaration and payment 
of such dividend or other distribution if such shares of Series A Stock, Series
B Stock, Series C Stock, Series D Stock or Series E Stock had been converted 
immediately prior to the record date for the determination of shareholders 
entitled to receive such dividend or other distribution.

                        (ii)    If the Corporation shall subdivide the 
outstanding shares of Common Stock into a greater number of shares of Common 
Stock, or combine the outstanding shares of Common Stock into a lesser number of
shares, or issue by reclassification of its shares of Common Stock any shares of
the Corporation, the Conversion Rate in effect immediately prior thereto shall 
be adjusted so that the holders of Series A Stock, Series B Stock, Series C 
Stock, Series D Stock 

                                       8
<PAGE>
 
and Series E Stock thereafter surrendered for conversion shall be entitled to
receive the number of shares of Common Stock which such holder would have owned
or been entitled to receive after the happening of any of the events described
above if such shares of Series A Stock, Series B Stock, Series C Stock, Series D
Stock and Series E Stock had been converted immediately prior to the happening
of such event on the day upon which such subdivision, combination or
reclassification, as the case may be, becomes effective.

                        (iii)   If, after the date of issuance of the Series A 
Stock, Series B Stock, Series C Stock, Series D Stock or Series E Stock, as the
case may be, the Corporation shall issue or sell any Additional Shares of 
Common Stock (as defined in paragraph 7 below) for a consideration per share 
less than the Conversion Amount for the Series A Stock, Series B Stock, Series 
C Stock, Series D Stock or Series E Stock, respectively, then the Conversion 
Rate with respect to such Series A Stock, Series B Stock, Series C Stock, 
Series D Stock or Series E Stock, as the case may be, shall be adjusted to the 
number determined by multiplying the Conversion Rate in effect immediately 
prior to such issuance or sale by a fraction, the numerator of which shall be 
the number of shares of Common Stock outstanding immediately prior to the 
issuance or sale of such Additional Shares of Common Stock plus (a) the number 
of such Additional Shares of Common Stock so issued or sold and (b) the number 
of shares of Common Stock then issuable upon conversion of all outstanding 
options to the extent that the conversion or exercise prices thereof are less 
than or equal to the price at which the Series A Stock, Series B Stock, Series 
C Stock, Series D Stock or Series E Stock, as the case may be, is convertible 
and the denominator of which shall be the number of shares of Common Stock 
outstanding immediately prior to the issuance or sale of such Additional Shares 
of Common Stock plus (a) the number of shares of Common Stock which the 
aggregate consideration for such Additional Shares of Common Stock so issued or
sold would purchase at a consideration per share equal to the Conversion Amount
and (b) the number of shares of Common Stock then issuable upon conversion of 
all outstanding shares of convertible securities and the exercise of all then 
outstanding options to the extent that the conversion or exercise prices thereof
are less than or equal to the price at which the Series A Stock, Series B Stock,
Series C Stock, Series D Stock or Series E Stock, as the case may be, is 
convertible.  For the purposes of this subparagraph (iii), the date as of which
the Conversion Amount shall be computed shall be earlier of (a) the date on 
which the Corporation shall enter into a firm contract for the issuance or sale
of such Additional Shares of Common Stock or (b) the date of the actual issuance
or sale of such Additional Shares.

                        (iv)    If the Corporation shall issue or sell any 
warrants, options or other rights entitling the holders thereof to subscribe for
or purchase either any Additional Shares of Common Stock or evidence of 
indebtedness, shares of stock or other securities which are convertible into or
exchangeable, with or without payment of additional consideration in cash or 
property, for Additional Shares of Common Stock (such convertible or 
exchangeable evidences of indebtedness, shares of stock or other securities 
hereinafter being called "Convertible Securities"), and the consideration per 
share for which Additional Shares of Common Stock may at any time thereafter be
issuable pursuant to such warrants, options or other rights or pursuant to the 
terms of such Convertible Securities (when added to the consideration per share
of Common Stock, if any, received for such warrants, options or other rights), 
shall be less than the Conversion Amount of the Series A Stock, Series B Stock,
Series C Stock, 

                                       9
<PAGE>
 
Series D Stock or Series E Stock, respectively, then the Conversion Rate with
respect to the Series A Stock, Series B Stock, Series C Stock, Series D Stock or
Series E Stock, as the case may be, shall be adjusted as provided in
subparagraph 4(g)(iii) on the basis that (a) the maximum number of Additional
Shares of Common Stock issuable pursuant to all such warrants, options or other
rights or necessary to effect the conversion or exchange of all such Convertible
Securities shall be deemed to have been issued and (b) the aggregate
consideration (plus the consideration, if any, received for such warrants,
options or other rights) for such maximum number of Additional Shares of Common
Stock shall be deemed to be the consideration received and receivable by the
Corporation for the issuance of such Additional Shares of Common Stock pursuant
to such warrants, options or other rights or pursuant to the terms of such
Convertible Securities.

                        (v)     If the Corporation shall issue or sell 
Convertible Securities and the consideration per share for which Additional 
Shares of Common Stock may at any time thereafter be issuable pursuant to the 
terms of such Convertible Securities shall be less than the Conversion Amount of
the Series A Stock, Series B Stock, Series C Stock, Series D Stock or Series E 
Stock, respectively, then the Conversion Rate with respect to the Series A 
Stock, Series B Stock, Series C Stock, Series D Stock or Series E Stock, as the
case may be, shall be adjusted as provided in subparagraph 4(g)(iii) on the 
basis that (a) the maximum number of Additional Shares of Common Stock 
necessary to effect the conversion or exchange of all such Convertible 
Securities shall be deemed to have been issued and (b) the aggregate 
consideration for such maximum number of Additional Shares of Common Stock 
shall be deemed to be the consideration received and receivable by the 
Corporation for the issuance of such Additional Shares of Common Stock pursuant
to the terms of such Convertible Securities.  No adjustment of the Conversion 
Rate shall be made under this subparagraph 4(g)(v) upon the issuance of any 
Convertible Securities which are issued pursuant to the exercise of any 
warrants, options or other rights, if such adjustment shall previously have 
been made upon the issuance of such warrants, options or other rights pursuant 
to subparagraph 4(g)(iv).

                        (vi)    For the purposes of subparagraphs 4(g)(iv) and 
(v), the date as of which the Conversion Amount shall be computed shall be the 
earliest of (a) the date on which the Corporation shall take a record of the 
holders of its Common Stock for the purpose of entitling them to receive any 
warrants, options or other rights referred to in subparagraph 4(g)(iv) or to 
receive any Convertible Securities, (b) the date on which the Corporation shall
enter into a firm contract for the issuance of such warrants, options or other 
rights or Convertible Securities or (c) the date of the actual issuance of such
warrants, options or other rights or Convertible Securities.

                        (vii)   No adjustment of the Conversion Rate shall be 
made under subparagraph 4(g)(iii) upon the issuance of any Additional Shares of
Common Stock which are issued pursuant to the exercise of any warrants, options
or other rights or pursuant to the exercise of any conversion or exchange 
rights in any Convertible Securities, if such adjustment shall previously have 
been made upon the issuance of such Convertible Securities (or upon the 
issuance of any warrants, options or other rights therefor), pursuant to 
subparagraphs 4(g)(iv) or (v).

                        (viii)  If any warrants, options or other rights (or 
any portions thereof) which shall have given rise to an adjustment pursuant to 
subparagraph 4(g)(iv) or conversion rights pursuant to Convertible Securities 
which shall have given rise to an adjustment pursuant to subparagraph 4(g)(v) 
shall have expired or terminated without the exercise thereof and/or if by 

                                       10
<PAGE>
 
reason of the terms of such warrants, options or other rights or Convertible 
Securities there shall have been an increase or increases, with the passage of 
time or otherwise, in the price payable upon the exercise or conversion 
thereof, then the Conversion Rate with respect to the Series A Stock, Series B 
Stock, Series C Stock, Series D Stock or Series E Stock, as the case may be, 
hereunder shall be readjusted (but to no greater extent than originally 
adjusted) on the basis of (a) eliminating from the computation any Additional 
Shares of Common Stock corresponding to such warrants, options or other rights 
or conversion rights as shall have expired or terminated, (b) treating the 
Additional Shares of Common Stock, if any, actually issued or issuable pursuant
to the previous exercise of such warrants, options or other rights or of 
conversion rights pursuant to any Convertible Securities as having been issued 
for the consideration actually received and receivable therefor, and (c) 
treating any of such warrants, options or other rights or of conversion rights 
pursuant to any Convertible Securities which remain outstanding as being 
subject to exercise or conversion on the basis of such exercise or conversion 
price as shall be in effect at the time; provided, however, that any 
consideration which was actually received by the Corporation in connection with
the issuance or sale of such warrants, options, or other rights shall form part
of the readjustment computation even though such warrants, options or other 
rights shall have expired without the exercise thereof.  The Conversion Rate 
with respect to the Series A Stock, Series B Stock, Series C Stock, Series D 
Stock or Series E Stock, as the case may be, shall be adjusted as provided in 
subparagraph 4(g)(iii) as a result of any increase in the number of Additional 
Shares of Common Stock issuable, or any decrease in the consideration payable 
upon any issuance of Additional Shares of Common Stock, pursuant to any 
antidilution provisions contained in any warrants, options or other rights or 
in any Convertible Securities.

                        (ix)    (A)     In case any Additional Shares of Common
Stock, Convertible Securities or warrants, options or other rights to purchase 
any such Additional Shares of Common Stock or Convertible Securities shall be 
issued or sold for cash, the consideration received therefor shall be deemed to
be the amount received by the Corporation therefor.

                                (B)     In case any Additional Shares of Common
Stock, Convertible Securities or warrants, options or other rights to purchase 
any such Additional Shares of Common Stock or Convertible Securities shall be 
offered by the Corporation for subscription, the consideration received 
therefor shall be deemed to be the subscription price.

                                (C)     In case any Additional Shares of Common
Stock, Convertible Securities or warrants, options or other rights to purchase 
any such Additional Shares of Common Stock or Convertible Securities are sold to
underwriters or dealers for public offering without a subscription offering, the
consideration received therefor shall be deemed to be the initial public 
offering price.

                                (D)     In any such case covered by 
subparagraphs (A), (B), or (C) herein, in determining the amount of 
consideration received by the Corporation, if the consideration is in whole or 
in part consideration other than cash, the amount of the consideration shall be
deemed to be the fair value of such consideration as determined in good faith by
the Board of Directors of the Corporation.  If Additional Shares of Common Stock
shall be issued as part of a unit with warrants, options, or other rights, then
the amount of consideration for the warrants, option or other right shall be 
deemed to be the amount determined at the time of issuance by the 

                                       11
<PAGE>
 
Board of Directors of the Corporation. If the Board of Directors of the
Corporation shall not make any such determination, the consideration for the
warrant, option or other right shall be deemed to be zero.

                                (E)     In any such case covered by 
subparagraphs (A), (B), (C), or (D) herein, in determining the amount of 
consideration received by the Corporation (I) any amounts paid or receivable for
accrued interest or accrued dividends shall be excluded, and (II) any 
compensation, discounts, expenses paid or incurred or underwriting commissions 
or concessions paid in connection therewith shall not be deducted.

                                (F)     In any case covered by subparagraphs 
(A), (B) or (C) herein, there shall be added to the consideration received by 
the Corporation at the time of issuance or sale, the minimum aggregate amount of
additional consideration payable to the Corporation upon the exercise of such 
warrants, options or other rights which relate to Convertible Securities, the 
minimum aggregate amount of consideration, if any, payable upon the conversion 
or exchange thereof.

                                (G)     In case any Additional Shares of
Common Stock, Convertible Securities or any options, warrants or other rights 
to purchase such Additional Shares of Common Stock or Convertible Securities 
shall be issued in connection with any merger or consolidation in which the 
Corporation is the surviving corporation, the amount of consideration therefor 
shall be deemed to be the fair value, as determined by the Board of Directors of
the Corporation, of such portion of the assets and business of the 
non-surviving corporation or corporations as such Board shall determine to be 
attributable to such Additional Shares of Common Stock, Convertible Securities 
or warrants, options or other rights to purchase such Additional Shares of 
Common Stock or Convertible Securities.

                        (x)     In case the Corporation shall effect a 
reorganization, shall merge with or consolidate into another corporation, or 
shall sell, transfer or otherwise dispose of all or substantially all of its 
property, assets or business and, pursuant to the terms of such reorganization,
merger, consolidation or disposition of assets, shares of stock or other 
securities, property or assets of the Corporation, successor or transferee or 
an affiliate thereof or cash are to be received by or distributed to the 
holders of Common Stock, then each holder of Series A Stock, Series B Stock, 
Series C Stock, Series D Stock and Series E Stock shall be given a written 
notice from the Corporation informing each holder of the terms of such 
reorganization, merger, consolidation, or disposition of assets and of the 
record date thereof for any distribution pursuant thereto, at least ten days in
advance of such record date, and each holder of Series A Stock, Series B Stock,
Series C Stock, Series D Stock and Series E Stock shall have the right 
thereafter to receive, upon conversion of such Series A Stock, Series B Stock, 
Series C Stock, Series D Stock and Series E Stock, the number of shares of stock
or other securities, property or assets of the Corporation, successor or 
transferee or affiliate thereof or cash receivable upon or as a result of such 
reorganization, merger, consolidation or disposition of assets by a holder of 
the number of shares of Common Stock equal to the Conversion Rate immediately 
prior to such event, multiplied by the number of shares of Series A Stock, 
Series B Stock, Series C Stock, Series D Stock and Series E Stock as may be 
converted.  The provisions of this subparagraph (x) shall similarly apply to 
successive reorganizations, mergers, consolidations or dispositions of assets.

                                       12
<PAGE>
 
                        (xi)    If a purchase, tender or exchange offer is made
to and accepted by the holders of more than 50% of the outstanding shares of 
Common Stock, the Corporation shall not effect any consolidation, merger or sale
with the person having made such offer or with any affiliate of such person, 
unless prior to the consummation thereof each holder of shares of Series A 
Stock, Series B Stock, Series C Stock, Series D Stock and Series E Stock shall 
have been given a reasonable opportunity to elect to receive, upon conversion of
the shares of Series A Stock, Series B Stock, Series C Stock, Series D Stock and
Series E Stock then held by such holder, either the stock, securities, cash or 
assets then issuable with respect to the Common Stock or the stock, securities,
cash or assets issued to previous holders of the Common Stock in accordance with
such offer, or the equivalent thereof.

                        (xii)   The number of shares of Common Stock outstanding
at any given time shall not include shares owned or held by or for the account 
of the Corporation, and the disposition of such shares shall be considered an 
issue or sale of Common Stock, for the purposes of this subparagraph 4(g).

                        (xiii)  The Corporation will not pay or declare a 
dividend (other than in Common Stock) upon the Common Stock payable otherwise
than out of earnings or earned surplus (determined in accordance with generally
accepted accounting principles).

                        (xiv)   If a state of facts shall occur which, without 
being specifically controlled by the provisions of this subparagraph 4(g), would
not fairly protect the conversion rights of the Series A Stock, Series B Stock,
Series C Stock, Series D Stock and Series E Stock in accordance with the 
essential intent and principles of such provisions, then the Board of Directors
of the Corporation shall make an adjustment in the application of such 
provisions, in accordance with such essential intent and principles, so as to 
protect such conversion rights.

                        (xv)    Anything herein to the contrary notwithstanding,
no adjustment in the Conversion Rate shall be required unless such adjustment, 
either by itself or with other adjustments not previously made, would require a
change of a least 1% in such rate; provided, however, that any adjustment which
by reason of this subparagraph (xv) is not required to be made shall be carried
forward and taken into account in any subsequent adjustment.

                        (xvi)   All calculations under this subparagraph 4(g) 
shall be made to the nearest one-thousandth of a share.

                        (xvii)  Whenever the Conversion Rate shall be 
adjusted pursuant to this subparagraph 4(g), the Corporation shall forthwith 
obtain, and cause to be delivered to each holder of Series A Stock, Series B 
Stock, Series C Stock, Series D Stock, or Series E Stock as the case may be, a 
certificate signed by the principal financial or accounting officer of the 
Corporation, setting forth in reasonable detail the event requiring the 
adjustment and the method by which such adjustment was calculated (including a 
description of the basis on which the Board of Directors of the Corporation 
determined the fair value of any consideration other than cash pursuant to 
subparagraph 4(g)(ix)) and specifying the new Conversion Rate.  In the case 
referred to in subparagraph 4(g)(x), such a certificate shall be issued 
describing the amount and kind of stock, securities, property or assets or cash
which shall be receivable upon conversion of the Series A 

                                       13
<PAGE>
 
Stock, Series B Stock, Series C Stock, Series D Stock, or Series E Stock as the
case may be, after giving effect to the provisions of such subparagraph 4(g)(x).

                        (h)     The Corporation shall at all times reserve and 
keep available out of its authorized but unissued shares of Common Stock, solely
for the purpose of effecting the conversion of Series A Stock, Series B Stock, 
Series C Stock, Series D Stock and Series E Stock, the full number of shares of
Common Stock then deliverable upon the conversion or exchange of all shares of 
Series A Stock, Series B Stock, Series C Stock, Series D Stock and Series E 
Stock at the time outstanding.  The Corporation shall at all times, take such 
corporate action as shall be necessary in order that the Corporation may validly
and legally issue fully paid and nonassessable shares of Common Stock upon the 
conversion of Series A Stock, Series B Stock, Series C Stock, Series D Stock 
and Series E Stock in accordance with the provisions hereof.

                        (i)     No fractional shares of Common Stock or scrip 
representing fractional shares of Common Stock shall be issued upon any 
conversion of Series A Stock, Series B Stock, Series C Stock, Series D Stock or
Series E Stock, but, in lieu thereof, there shall be paid an amount in cash 
equal to the same fraction of the Conversion Amount of a whole share of Common 
Stock on the business day preceding the day of conversion.

                5.      Events of Default.      (a)  The occurrence of any of 
                        -----------------
the following shall constitute an Event of Default:

                        (i)     Default by the Corporation in failing to convert
the Series A Stock, Series B Stock, Series C Stock, Series D Stock or Series E
Stock, as the case may be, in accordance with the provisions hereof or to pay
more than one (1) declared dividend out of funds legally available as specified
herein or the failure to make any payment in accordance with paragraph 2 hereof,
in each case where the failure to perform continues uncured for at least ninety
(90) days;

                        (ii)    Any material default by the Corporation in the 
performance or observance of any of the covenants contained in Section 5 of that
certain Preferred Stock Purchase Agreement, dated as of June 1, 1989, among the
Corporation and certain Investors, (as such term is defined therein), as the 
same may be amended or the provisions thereof waived from time to time (the 
"Agreement"), (which Agreement is on file at the offices of the Corporation), 
which shall default continue uncured for at least ninety (90) days after notice
is given to the Corporation of such default;

                        (iii)   Any material breach by the Corporation of any of
the representations and warranties made by it in the Agreement which shall 
occur and be discovered and notice to the Corporation be given within six (6) 
months following the Closing Date under the Agreement and shall continue 
substantially uncured for at least ninety (90) days following the date of 
discovery and notice;

                        (iv)    The Corporation shall petition or apply to any 
tribunal for the appointment of a trustee or receiver of the Corporation or of 
any substantial part of its assets, or commence any proceedings relating to the
Corporation under any bankruptcy, reorganization, 

                                       14
<PAGE>
 
arrangement, insolvency, readjustment of debt, dissolution or liquidation law of
any jurisdiction, whether now or hereafter in effect; or any such petition or
application shall be filed, or any such proceeding commenced, against the
Corporation and the Corporation shall by any act indicate its approval thereof,
consent thereto or acquiescence therein; or an order shall be entered appointing
any such trustee or receiver, or adjudicating the Corporation bankrupt or
insolvent, or approving the petition in any such proceeding and such order shall
remain in effect for more than ninety (90) days; or an order shall be entered in
any proceeding against the Corporation decreeing the dissolution or split-up of
the Corporation, and such order shall remain in effect for more than ninety (90)
days.

                        (b)     If an Event of Default shall have occurred, 
then the holders of the Series A Stock, Series B Stock, Series C Stock and 
Series D Stock shall have the right, voting together as a single class, to 
elect such number of directors of the Corporation as following such election 
shall constitute a majority of the entire Board of Directors (which majority 
shall include any directors already serving solely as representatives of the 
Series A Stock, Series B Stock, Series C Stock or Series D Stock pursuant to 
the Agreement), the remaining directors to be elected by the classes or series 
of stock (including the Series A Stock, Series B Stock, Series C Stock and 
Series D Stock) entitled to vote therefor.  The directors elected pursuant to 
this subparagraph 5(b) shall not be part of any class of directors, other than 
the class created by this subparagraph 5(b).  Each such director shall have a 
vote equal to the vote of any other director of the Corporation. Such directors
shall serve until the next annual meeting of shareholders or until such earlier
time as (i) they may be removed by a majority vote of the holders of Series A 
Stock, Series B Stock, Series C Stock and Series D Stock voting together as a 
single class or (ii) the holders of Series A Stock, Series B Stock, Series C 
Stock, Series D Stock no longer have the right to elect such directors.  If and
when such right of the holders of the Series A Stock, Series B Stock, Series C 
Stock and Series D Stock becomes operative, the maximum authorized number of 
members of the Board of Directors of the Corporation shall automatically be 
increased to the extent necessary to create any vacancy to be filled only by 
vote of the holders of the Series A Stock, Series B Stock, Series C Stock and 
Series D Stock then outstanding as hereinafter set forth.  Whenever such right 
of the holders of the Series A Stock, Series B Stock, Series C Stock and Series
D Stock shall become operative, such right shall be exercised initially either 
at a special meeting of the holders of the Series A Stock, Series B Stock, 
Series C Stock and Series D Stock called as provided below or at any annual 
meeting of shareholders held for the purpose of electing directors, and 
thereafter at such annual meetings.  The directors elected pursuant to this 
subparagraph 5(b) shall be elected by a plurality of the votes cast.  The right
of the holders of the Series A Stock, Series B Stock, Series C Stock and Series
D Stock voting together as a single class and separately from all other classes
and series, to elect a majority of the members of the Board of Directors of the
Corporation as aforesaid shall continue until such time as the Event of Default
has been cured, at which time the right of the holders of the Series A Stock, 
Series B Stock, Series C Stock and Series D Stock with respect to which such 
Event of Default has been cured to elect such directors under this subparagraph
5(b) shall terminate (subject to becoming operative again in the event of any 
subsequent Event of Default) and the maximum authorized number of members of 
the Board of Directors of the Corporation shall automatically be reduced if 
such number was increased at the time when the terminated voting right of the 
holders of the Series A Stock, Series B Stock, Series C and Series D Stock 
became operative.

        At any time when the voting right of the holders of the Series A Stock,
Series B Stock, Series C Stock and Series D Stock provided in this subparagraph
5(b) shall have become operative and not have been exercised, a proper officer 
of the Corporation shall, upon the written request of the holders of record of 
at least fifteen percent (15%) of the shares of Series A Stock, Series B Stock,
Series C Stock and Series D Stock, counted together as a single class, then 
outstanding addressed to the Secretary of the Corporation, call a special 
meeting of the holders of the Series A Stock, Series B Stock, Series C Stock and
Series D Stock for the purpose of electing the directors to be elected by the 
holders of the Series A Stock, Series B Stock, Series C Stock, and Series D 
Stock.  Such meeting shall be held at the earliest practicable date upon the 
notice required for meetings of shareholders at such place in the continental 
United States as may be specified in such written request.  If such meeting 
shall not be called by the proper officer of the Corporation within seven (7) 
days after the personal service of such written request upon the Secretary of 
the Corporation, or within seven (7) days after mailing the same within the 
United States by registered or certified mail enclosed in a postage paid 
envelope addressed to the Secretary of the Corporation at its principal office,
then the holders of record of at least fifteen percent (15%) of the Series A 
Stock, Series B Stock, Series C Stock and Series D Stock, counted together as a
single class, then outstanding may designate in writing one of their number to 
call such meeting at the expense of the Corporation, and such meeting may be 
called by the person so designated upon the notice required for meetings of 
shareholders and shall be held at such place in the continental United States 
as may be specified in such notice.

        Upon any termination of the right of the holders of the Series A Stock,
Series B Stock, Series C Stock and Series D Stock to vote for directors as 
herein above provided, the term of office of any director then in office elected
by the holders of the Series A Stock, Series B Stock, Series C Stock and Series
D Stock shall terminate immediately.  If the office of any director elected by 
the holders of the Series A Stock, Series B Stock, Series C Stock and Series D 
Stock becomes vacant by reason of death, resignation, retirement, 
disqualification, removal from office or otherwise, then the procedure provided
for in this subparagraph 5(b) shall be used to fill the vacancy.

        The Bylaws of the Corporation shall automatically be deemed amended 
from time to time to provide for the increase or reduction in the maximum 
authorized number of members of the Board of Directors and for the election 
procedure as herein above provided in this subparagraph 5(b).  Whenever holders
of Series A Stock, Series B Stock, Series C Stock or Series D Stock, as the 
case may be, are required or permitted to take any action by vote, such action 
may be taken without a meeting on written consent, setting forth the action so 
taken and signed by the holders of the outstanding Series A Stock, Series B 
Stock, Series C Stock or Series D Stock, as the case may be, having not less 
than the minimum number of votes that would be necessary to authorize or take 
such action at a meeting at which all such shares entitled to vote thereon were
present and voted.

                6.      Voting Rights.  (a)  Except as otherwise provided herein
                        -------------
for the election of directors or as required by the Delaware General Corporation
Law, the holders of shares of Series A Stock, Series B Stock, Series C Stock, 
Series D Stock and Series E Stock shall have the right to vote, together with 
the holders of all the outstanding shares of Series A Stock, Series B Stock, 
Series C Stock, Series D Stock, Series E Stock, and Common Stock and not by 
classes, on all matters on which holders of Series A Stock, Series B Stock, 
Series C Stock, Series 

                                       16
<PAGE>
 
D Stock, Series E Stock and/or Common Stock shall have the right to vote. The
holders of shares of Series A Stock, Series B Stock, Series C Stock, Series D
Stock and Series E Stock shall have the right to cast one vote for each share of
Common Stock into which each share of Series A Stock, Series B Stock, Series C
Stock, Series D Stock or Series E Stock held by them is convertible, with any
fractions rounded to the next full vote.

                (b)     Without the prior approval of the holders of a majority
of the shares of Series A Stock, Series B Stock and Series C Stock outstanding,
voting together as a single class, the Corporation will not (i) authorize, 
create or issue any series or shares of capital stock senior or pari passu to 
                                                                ---- -----

issue any stock options or stock purchase plan for, or otherwise issue any stock
options to, employees, consultants or directors of the Corporation, except that
the Corporation may authorize options for employees, directors or consultants to
purchase up to 519,477 shares of Common Stock; provided, however, that nothing 
                                               --------  -------
contained herein will limit the Corporation's ability to resell any shares from
time to time contained in the treasury of the Corporation, or (ii) take any 
action which would materially alter or adversely affect the rights of the 
holders of the Series A Stock, Series B Stock or Series C Stock set forth 
herein.

                (c)     Without the prior approval of the holders of a majority
of the shares of Series D Stock outstanding, the corporation will not authorize,
create or issue any series or shares of capital stock senior or pari passu to 
the Series D Stock or take any action which would materially alter or adversely
affect the rights of the holders of the Series D Stock if such action would give
the Series D Stock the right to a vote on such action as a separate series under
Section 242(b)(2) of the Delaware General Corporation Law.

                7.      Definitions.

prescribed by the law of the State of Delaware, to provide for the issuance of 
the shares of Preferred Stock in one or more series, and, by filing a 
certificate of designation pursuant to the applicable law of the State of

writing without a meeting, may authorize another person or persons to act for
such stockholder by proxy.  Such a proxy may be prepared, transmitted and
delivered in any manner permitted by applicable law.  If a vote is to be taken
by written ballot, then each such ballot shall state the name of the stockholder
or proxy voting and such other information as the chairman of the meeting deems
appropriate.  Directors shall be elected by a plurality of the votes of the
shares present in person or represented by proxy at the meeting and entitled to
vote on the election of directors.  Unless otherwise provided by applicable law,

a majority of the shares of stock entitled to vote thereon that are present in
person or represented by proxy at the meeting and are voted for or against the
matter.

proxies, any envelopes submitted with those proxies, any information provided in
connection with proxies in accordance with Section 212(c)(2) of the Delaware
General Corporation Law, ballots and the regular books and records of the

for the limited purpose of reconciling proxies and ballots submitted by or on
behalf of banks, brokers, their nominees or similar persons which represent more
votes than the holder of a proxy is authorized by the record owner to cast or
more votes than the stockholder holds of record.  If the inspectors consider
other reliable information for the limited purpose permitted herein, the
inspectors at the time they make their certification of their determinations
pursuant to this Section 1.11 shall specify the precise information considered
by them, including the person or persons from whom they obtained the
information, when the information was obtained, the means by which the
information was obtained and the basis for the inspectors' belief that such
information is accurate and reliable.

director or officer, to repay all amounts so advanced if it should be determined
ultimately that such director or officer is not entitled to be indemnified under
this Article VI or otherwise; and provided, further, that the Corporation shall
                                  --------  -------
not be required to advance any expenses to a person against whom the Corporation

counted for such purpose, if: (i) the material facts as to his, her or their
relationship or interest and as to the contract or transaction are disclosed or

     WHEREAS, each Shareholder would like to grant to the Company, and then to
certain persons, a right of first refusal with respect to any securities of the
Company which the Shareholder proposes to sell or otherwise dispose of, and make
certain other agreements contained herein.

     NOW, THEREFORE, in consideration of the foregoing and of the mutual
covenants, terms and conditions set forth herein, the parties hereby agree as
follows:

     1.  Restrictions on Sale.  During the term of this Agreement, each
         --------------------                                          
Shareholder shall not sell, assign, dispose of, transfer, pledge, or hypothecate
any Securities, whether by operation of law or otherwise, except as expressly
permitted by this Agreement.

     2.  Right of First Refusal.  If a Shareholder (the "Selling Shareholder")
         ----------------------

and the Company shall notify each holder of 10% or more of the Company's
outstanding shares of stock on a fully diluted basis, assuming conversion of all
outstanding convertible securities and the exercise of all outstanding options
(each, a "Qualified Shareholder" and collectively, the "Qualified
Shareholders"), in writing (the "Notice"), setting forth in reasonable detail
the terms and conditions of the proposed disposition of such Securities (which
must be for cash or other consideration with readily ascertainable cash 
<PAGE>

independent third party offeree) and shall offer the Securities to the Company,
and then to the Qualified Shareholders, as provided hereinafter on the same
terms and conditions.

          (a) Within thirty (30) days after receipt of the Notice, the Company

     purchase all or a portion of the Offered Securities.

          (b) If any of the Offered Securities are not to be purchased by the
     Company pursuant to subsection (a) above (the "Unsold Securities"), the
     Qualified Shareholders shall have the right to purchase all or a portion of
     the Unsold Securities pro rata based on the number of shares of common
                           --- ----                                        
     stock of the Company ("Common Stock") held by each Qualified Shareholder
     (assuming conversion of all outstanding convertible securities and the
     exercise of all outstanding options) to the total number of shares of
     Common Stock held by all Qualified Shareholders (assuming conversion of all
     outstanding convertible securities and the exercise of all outstanding
     options).  Such right shall be exercised within the later of (i) ten (10)
     business days after the receipt of the Company Exercise Notice delivered
     pursuant to subsection (a) above, or (ii) if no Company Exercise Notice is
     given, ten (10) business days after the expiration of the thirty (30)-day
     period specified in subsection (a) above by written notice ("Shareholder
     Exercise Notice") delivered or mailed to the Selling Shareholder as
     provided in Section 12 below.  The closing of such purchase shall take

     Shareholder may also indicate in such notice a number of Unsold Securities
     in excess of its pro rata share, determined as hereinabove provided, if
                      --------                     
     any, that it would be willing to purchase if such remain unsold after
     completion of the offering of Unsold Securities as hereinabove provided.
     Any such remaining Unsold Securities shall be sold to those Qualified
     Shareholders who requested to purchase them on a proportionate basis.

          (c) On the date fixed for closing pursuant to subsection (a) or (b)
     above, the Selling Shareholder shall deliver to the purchaser(s) the
     certificates representing the Offered Securities sold to such purchaser(s),
     free and clear of all liens and encumbrances (other than legends on share
     certificates in respect of applicable securities laws and contractual
     restrictions such as those set forth in this agreement) and properly
     endorsed for transfer and each purchaser shall pay the purchase price for
     the Offered Securities purchased by it by delivery of a check payable to
     the Selling Shareholder.

          (d) If all Offered Securities referred to in the Notice are not
     elected to be purchased pursuant to subsections (a) and (b) above, the
     Selling Shareholder may, luring the ninety (90)-day period following the
     expiration of the ten (10)-day period provided for in subsection (b) above,
     sell any remaining Offered Securities not so purchased to the proposed
     transferee on the same terms as specified in the Notice.  If the Selling
     Shareholder shall not have sold such Offered Securities within such period
     or the terms of sale shall have changed, the right provided hereunder shall
     be deemed to be revived, and such Securities shall not be sold unless first
     reoffered to the Company, and then to the Qualified Shareholders, in
     accordance herewith.

     3.  Effectiveness of Agreement.  (a) This Agreement shall be effective upon

sale and distribution of the securities being offered by the Company, then the

               ---------------------------------

of, or constitute a default under or an event which, with or without notice or
lapse of time or each, would be a breach of or default under or violation of the
Certificate of Incorporation or By-Laws of the Company or would be a breach of
or default under or violation of any material agreement, document, indenture,
mortgage or other instrument or undertaking by which the Company is bound or to
which any of its properties are subject, or would be a material violation of any
law, administrative regulation, judgment, order or decree applicable to the
Company; (ii) result in the creation or imposition of any material lien, charge
or encumbrance upon any property or assets of the Company; (iii) result in the
loss of any material license, certificate, legal privilege or legal right

agreement to which the Company is a party a right of termination; or (v) except

of Common Stock required for issuance upon the conversion of all of the
Preferred Shares (including any additional shares of Common Stock which may
become so issuable by reason of the operation of anti-dilution provisions of the
Preferred Shares).

          ----------------------------------------------------------

following legend on each certificate representing the Preferred Shares and on
each certificate representing the Conversion Shares:

          "THE SHARES EVIDENCED BY THIS CERTIFICATE HAVE NOT BEEN
          REGISTERED UNDER THE SECURITIES ACT OF 1933 AND MAY NOT BE
          TRANSFERRED OR SOLD UNLESS (i) A REGISTRATION STATEMENT
          UNDER SUCH ACT IS THEN IN EFFECT WITH RESPECT THERETO, (ii)
          A WRITTEN OPINION FROM COUNSEL FOR THE ISSUER OF MESSRS.
          STROOCK & STROOCK & LAVAN OR OTHER COUNSEL FOR THE HOLDER
          REASONABLY ACCEPTABLE TO THE ISSUER HAS BEEN OBTAINED TO THE
          EFFECT THAT NO SUCH REGISTRATION IS REQUIRED OR (iii) A 'NO
          ACTION' LETTER OR ITS THEN EQUIVALENT HAS BEEN ISSUED BY THE
          STAFF OF THE SECURITIES AND EXCHANGE COMMISSION WITH RESPECT
          TO SUCH TRANSFER OR SALE."

          3.2. Restricted Securities. Each Investor understands that the
               ---------------------
Preferred Shares (and any Conversion Shares) have not been registered under the
Securities Act of 1933 for the reason that the sale provided for in this
Agreement is exempt pursuant to Section 4 of the Securities Act of 1933 and that
the reliance of the Company on such exemption is predicated in part on such
Investor's representations set forth herein. Each Investor represents that it is
experienced in evaluating companies such as the Company, is able to fend for
itself, has such knowledge and experience in financial and business matters as
to be capable of evaluating the merits and risks of its investment, and has the
ability to suffer the total loss of its investment. Such Investor was not formed
solely for the purpose of investing in the Company. Each Investor further
represents that it has had access during the course of the transaction and prior
to its purchase of the Preferred Shares to such information relating to the
Company as it has desired and that it has had 

                                       5

<PAGE>
 
the opportunity to ask questions of and receive answers from the Company
concerning the terms and conditions of the offering and to obtain additional
information (to the extent the Company possessed such information or could
acquire it without unreasonable effort or expense) necessary to verify the
accuracy of any information furnished to it or to which it had access.

     Each Investor understands that the Preferred Shares (and any Conversion
Shares) may not be sold, transferred or otherwise disposed of without
registration under the Securities Act of 1933 or an exemption therefrom and that
in the absence of an effective registration statement covering the Preferred
Shares (or the Conversion Shares) or an available exemption from registration
under the Securities Act of 1933, the Preferred Shares (and any Conversion
Shares) must be held indefinitely.  The benefits of Rule 144 promulgated under
the Securities Act of 1933 are not presently available, the Company has not
covenanted to make the benefits of such Rule available, and the Company has no
present plans to make the benefits of such Rule available.

     4.  Deliveries of the Company.  On May 7, 1991, as a condition to the
         -------------------------

and keep available out of its authorized but unissued Common Stock the number of
shares of Common Stock required for issuance upon the conversion of all of the
Preferred Shares and Exercise Shares (including any additional shares of Common

               2.8.   Litigation.  Except as set forth on Schedule 2.8 attached
                      ----------

sheet fairly presents the financial condition of the Company as of its date and
each statement of income fairly presents the results of operations of the
Company for the period covered thereby.

         3.    Representations, Warranties and Covenants of the Investors.  Each
               -----------------------------------------------------------      
Investor hereby severally represents and warrants to, and agrees with, the
Company as follows effective as of the delivery of the Purchase Price and the
exercise of the Warrants:

               3.1.   Investment Intent.  Each Investor is acquiring the
                      ------------------                                
Securities and Exercise Shares (and any Conversion Shares) for its own account
and not with a present view to, or for sale in connection with, any distribution
thereof in violation of the Securities Act of 1933.  Each Investor consents to
the placement of the following legend on each certificate representing the
Preferred Shares, on each certificate representing the Exercise Shares, on each
certificate representing the Conversion Shares and/or each Warrant:

         "THE SECURITIES EVIDENCED HEREBY HAVE NOT BEEN REGISTERED
         UNDER THE SECURITIES ACT OF 1933 AND MAY NOT BE TRANSFERRED
         OR SOLD UNLESS (i) A REGISTRATION STATEMENT UNDER SUCH ACT IS
         THEN IN EFFECT WITH RESPECT THERETO, (ii) A WRITTEN OPINION
         FROM COUNSEL FOR THE ISSUER OR MESSRS. STROOCK & STROOCK &
         LAVAN OR OTHER COUNSEL FOR THE HOLDER REASONABLY ACCEPTABLE
         TO THE ISSUER HAS BEEN OBTAINED TO THE EFFECT THAT NO SUCH
         REGISTRATION IS REQUIRED OR (iii) A 'NO ACTION' LETTER OR ITS
         THEN EQUIVALENT HAS BEEN ISSUED BY THE STAFF OF THE
         SECURITIES AND EXCHANGE COMMISSION WITH RESPECT TO SUCH
         TRANSFER OR SALE."

               3.2.   Restricted Securities.  Each Investor understands that the
                      ----------------------
Securities and Exercise Shares (and any Conversion Shares) have not been
registered under the Securities Act of 1933 for the reason that the sale
provided for in this Agreement is exempt pursuant to Section 4 of the Securities
Act of 1933 and that the reliance of the Company on such exemption is predicated
in part on such Investor's representations set forth herein.  Each Investor
represents that it is experienced in evaluating companies such as the Company,
is able to fend for itself, has such knowledge and experience in financial and
business matters as to be capable of evaluating the 

                                      -8-

<PAGE>
 
merits and risks of its investment, and has the ability to suffer the total loss
of its investment. Such Investor was not formed solely for the purpose of
investing in the Company. Each Investor further represents that it has had
access during the course of the transaction and prior to its purchase of the
Securities and Exercise Shares to such information relating to the Company as it
has desired and that it has had the opportunity to ask questions of and receive
answers from the Company concerning the terms and conditions of the offering and
to obtain additional information (to the extent the Company possessed such
information or could acquire it without unreasonable effort or expense)
necessary to verify the accuracy of any information furnished to it or to which
it had access.

         Each Investor understands that the Securities and Exercise Shares (and
any Conversion Shares) may not be sold, transferred or otherwise disposed of
without registration under the Securities Act of 1933 or an exemption therefrom
and that in the absence of an effective registration statement covering the
Securities and Exercise Shares (or the Conversion Shares) or an available
exemption from registration under the 1933 Act, the Securities and the Exercise
Shares (and any Conversion Shares) must be held indefinitely.  The benefits of
Rule 144 promulgated under the Securities Act of 1933 are not presently
available, the Company has not covenanted to make the benefits of such Rule
available, and the Company has no present plans to make the benefits of such
Rule available.

         4.    Deliveries of the Company.  On the Closing Date, as a condition

          2.2. CHARTER DOCUMENTS.  The Company has heretofore made available to
               -----------------                                               
the Investors true, correct and complete copies of the Company's Certificate of
Incorporation, as amended (the "Certificate of Incorporation") and By-Laws, each
as in full force and effect on the Closing Date.

          2.3. CAPITALIZATION.  As of the date hereof, the Company's authorized
               --------------                                                  
capitalization consists of 3,888,166 shares of Common Stock, par value $.01 per
share, of which 938,229 shares are outstanding; and 1,638,166 shares of

Schedule 2.3 attached hereto is a list of the aggregate number of outstanding
securities of the Company. Except pursuant to the 1989 Agreement, the 1991

person is entitled to any preemptive rights with respect to the purchase or sale
of any securities by the Company. When issued and sold to the Investors, the
Preferred Shares will be duly and validly issued, fully paid and non-assessable,

upon conversion of the Preferred Shares, will be duly and validly issued, fully
paid and non-assessable. Except as set forth on Schedule 2.3 attached hereto,
there are no outstanding options, warrants or other rights, commitments or

Schedule 2.4, to the Company's best knowledge, the Company is not in material
default in the performance of any material obligation, agreement, instrument or
undertaking to which it is a party or by which it is bound. The Company is not
in violation of its Certificate of Incorporation or By-Laws. Neither the sale of
the Preferred Shares (or the issuance and delivery of the Conversion Shares),
the execution and delivery of this Agreement, nor the fulfillment of the terms
set forth in this Agreement and the consummation of the transactions
contemplated by this Agreement, will: (i) conflict with or constitute a breach
of, or constitute a default under or an event which, with or without notice or
lapse of time or each, would be a breach of or default under or violation of the
Certificate of Incorporation or By-Laws of the Company or would be a breach of
or default under or violation of any material agreement, document, indenture,
mortgage or other instrument or undertaking by which the Company is bound or to
which any of its properties are subject, or would be a material violation of any
law, administrative regulation, judgment, order or decree applicable to the
Company; (ii) result in the creation or imposition of any material lien, charge
or encumbrance upon any property or assets of the Company; (iii) result in the
loss of any material license, certificate, legal privilege or legal right

agreement to which the Company is a party a right of termination; or (v) except
as provided for in this Agreement, require the consent of any other person or
entity under any agreement, indenture, mortgage, document or other instrument or
undertaking by which the Company is bound or to which any of its properties are
subject.

          2.5. AUTHORIZATION.  The Company has the full corporate power and
               -------------                                               
authority to enter into this Agreement and to perform all of its obligations
hereunder.  The execution, delivery and performance of the terms of this
Agreement by the Company have been duly authorized by all necessary corporate
action.  This Agreement constitutes a legal, valid and binding obligation of the
Company enforceable in accordance with its terms.  The Company, in light of its
business or proposed business, does not require any consent, approval,
authorization or order of, or declaration, filing or registration with, any
court or governmental or regulatory agency or board in connection with the
execution and delivery of this Agreement and the consummation of the
transactions contemplated hereby.

          2.6. COMPLIANCE WITH THE SECURITIES ACT.  Based upon the
               ----------------------------------                 
representations of the Investors set forth herein, and assuming the truth of
such representations, the offer, sale and issuance of the Preferred Shares (and
the issuance and delivery of the Conversion Shares) are exempt from the
registration requirements of the Securities Act of 1933.

          2.7. RESERVATION OF COMMON STOCK.  The Company shall reserve and keep

<PAGE>
 
Stock required for issuance upon the conversion of all of the Preferred Shares
(including any additional shares of Common Stock which may become so issuable by
reason of the operation of anti-dilution provisions of the Preferred Shares).

          2.8. LITIGATION.  Except as set forth on Schedule 2.8 attached hereto,
               ----------

threatened in writing, any litigation, action, suit or proceeding:  (i) to which
the Company is or will be a party in or before or by any court or governmental
or regulatory agency or body; or (ii) to which any of the officers or employees
of the Company is or will be a party in or before or by any court or
governmental or regulatory agency or body, concerning termination by such person
of his or her employment with any of such person's former employers.  In
addition to the foregoing, there is no judgment, decree, injunction, rule or
order of any court, governmental department, commission, agency, instrumentality
or arbitrator outstanding against the Company having any material adverse effect
on the business or proposed business or operations, properties, assets or
condition, financial or otherwise, of the Company.

          2.9. COMPLIANCE WITH LAW.  To its knowledge, the Company is in

                 --------------------                                           
audited balance sheets of the Company at April 30, 1992, and the related
statements of income and retained earnings and changes in financial position,
including the notes thereto, of the Company for the periods then ended, and the
unaudited balance sheet of the Company at April 30, 1993 and the related
statements of income for the period then ended.  The financial statements
referred to above have been prepared in conformity with generally accepted
accounting principles consistently applied subject in the case of the interim
statements to normal year-end audit adjustments, and each balance sheet fairly
presents the financial condition of the Company as of its date and each
statement of income fairly presents the results of operations of the Company for
the period covered thereby.

     3.   REPRESENTATIONS, WARRANTIES AND COVENANTS OF THE INVESTORS.  Each
          ----------------------------------------------------------       
Investor hereby severally represents and warrants to, and agrees with, the
Company as follows effective as of the delivery of the Purchase Price:

          3.1.   INVESTMENT INTENT.  Each Investor is acquiring the Preferred
                 -----------------                                           
Shares (and any Conversion Shares) for its own account and not with a present
view to, or for sale in connection with, any distribution thereof in violation
of the Securities Act of 1933.  Each Investor consents to the placement of the
following legend on each certificate representing the Preferred Shares and on
each certificate representing the Conversion Shares:

          "THE SECURITIES EVIDENCED HEREBY HAVE NOT BEEN REGISTERED UNDER THE
          SECURITIES ACT OF 1933 AND MAY NOT BE TRANSFERRED OR SOLD UNLESS (i) A
          REGISTRATION STATEMENT UNDER SUCH ACT IS THEN IN EFFECT WITH RESPECT
          THERETO, (ii) A 

                                       4

<PAGE>
 
          WRITTEN OPINION FROM COUNSEL FOR THE ISSUER OR COUNSEL FOR THE HOLDER
          REASONABLY ACCEPTABLE TO THE ISSUER HAS BEEN OBTAINED TO THE EFFECT
          THAT NO SUCH REGISTRATION IS REQUIRED OR (iii) A 'NO ACTION' LETTER OR
          ITS THEN EQUIVALENT HAS BEEN ISSUED BY THE STAFF OF THE SECURITIES AND
          EXCHANGE COMMISSION WITH RESPECT TO SUCH TRANSFER OR SALE."

          3.2. RESTRICTED SECURITIES.  Each Investor understands that the
               ---------------------                                     
Preferred Shares (and any Conversion Shares) have not been registered under the
Securities Act of 1933 for the reason that the sale provided for in this
Agreement is exempt pursuant to Section 4 of the Securities Act of 1933 and that
the reliance of the Company on such exemption is predicated in part on such
Investor's representations set forth herein.  Each Investor represents that it
is experienced in evaluating companies such as the Company, is able to fend for
itself, has such knowledge and experience in financial and business matters as
to be capable of evaluating the merits and risks of its investment, and has the
ability to suffer the total loss of its investment.  Such Investor was not
formed solely for the purpose of investing in the Company.  Each Investor
further represents that it has had access during the course of the transaction
and prior to its purchase of the Preferred Shares to such information relating
to the Company as it has desired and that it has had the opportunity to ask
questions of and receive answers from the Company concerning the terms and
conditions of the offering and to obtain additional information (to the extent
the Company possessed such information or could acquire it without unreasonable
effort or expense) necessary to verify the accuracy of any information furnished
to it or to which it had access.

     Each Investor understands that the Preferred Shares (and any Conversion
Shares) may not be sold, transferred or otherwise disposed of without
registration under the Securities Act of 1933 or an exemption therefrom and that
in the absence of an effective registration statement covering the Preferred
Shares (or the Conversion Shares) or an available exemption from registration
under the 1933 Act, the Preferred Shares (and any Conversion Shares) must be
held indefinitely.  The benefits of Rule 144 promulgated under the Securities
Act of 1933 are not presently available, the Company has not covenanted to make
the benefits of such Rule available, and the Company has no present plans to
make the benefits of such Rule available.

     4.   DELIVERIES OF THE COMPANY.  On the Closing Date, as a condition to the
          -------------------------

correct as of the Closing Date.

     5.   DELIVERIES OF THE COMPANY UPON SUPPLEMENTAL CLOSING.  As a condition

purchased in the Supplemental Closing, if any, the Company will deliver to DBDI

and (iii) provide that the definition of "Securities" includes all securities
received in exchange for or upon conversion, exercise or in replacement of the

          (D)  The Investors, on behalf of themselves as holders of Series A

issuance and delivery of the Conversion Shares) are exempt from the registration
requirements of the Securities Act.

               2.20.  Pension Plans. Except as set forth on Schedule 2.20
                      -------------
attached hereto, the Company does not have any pension, health, retirement,
profit sharing, bonus, stock purchase, stock option, severance or similar
employee benefit plans or obligations subject to the Employee Retirement Income
Security Act of 1974, and does not have any other stock purchase or stock option
plans.

               2.21.  Insurance. The Company maintains valid policies of
                      ---------
workers' compensation insurance and such insurance with respect to its
properties and business of the kinds and in the amounts as set forth on Schedule
2.21 attached hereto. The activities and operations of the Company have been
conducted in a manner so as to conform in all material respects to all
applicable provisions of such insurance policies. Such policies are valid and
enforceable in accordance with their terms and are in full force and effect. The
Company is not in material default with respect to any provision contained in
any such policy and has not materially failed to give any notice or present any
claim under any such policy in due and timely fashion.

There are no outstanding unpaid claims under any such policy. The Company has
not received notice of, nor has it knowledge of, any inaccuracy in any
application for such policies, any failure to pay premiums when due or any
similar state of facts that might form the basis for termination of any such
insurance. The Company has not canceled or terminated any insurance policy
listed on Schedule 2.21, nor has any insurance company canceled or terminated
any such insurance policy of the Company.

               2.22.  Financial Statements. Attached hereto as Exhibit E are the
                      --------------------
audited balance sheets of the Company at April 30, 1987, and April 30, 1988, and
the related statements of income and retained earnings and changes in financial
position, including the notes thereto, of the Company for the periods then
ended, and the unaudited balance sheet of the Company at March 31, 1989 and the
related statements of income for the period then ended. The financial statements
referred to above have been prepared in conformity with generally accepted
accounting principles consistently applied subject in the case of the interim
statements to normal year-end audit adjustments, and each balance sheet fairly
presents the financial condition of the Company as of its date and each
statement of income fairly presents the results of operations of the Company for
the period covered thereby.

          3.   Representations, Warranties and Covenants of the Investors.  Each
               ----------------------------------------------------------       
Investor hereby severally represents and warrants to, and agrees with, the
Company as follows:

               3.1. Investment Intent. Each Investor is acquiring the Preferred
                    -----------------
Shares (and any Conversion Shares) for its own account and not with a present
view to, or for sale in connection with, any distribution thereof in violation
of the Securities Act. Each Investor consents to the placement of the following
legend on each certificate representing the Preferred Shares and on each
certificate representing the Conversion Shares:

          "THE SHARES EVIDENCED BY THIS CERTIFICATE HAVE NOT BEEN
          REGISTERED UNDER THE SECURITIES ACT OF 1933 AND MAY NOT BE
          TRANSFERRED OR SOLD UNLESS (i) A REGISTRATION STATEMENT
          UNDER SUCH ACT IS THEN IN EFFECT WITH RESPECT THERETO, (ii)
          A WRITTEN OPINION FROM COUNSEL FOR THE ISSUER OR MESSRS.
          STROOCK & STROOCK & LAVAN OR OTHER

                                      -11-
<PAGE>
 
          COUNSEL FOR THE HOLDER REASONABLY ACCEPTABLE TO THE ISSUER
          HAS BEEN OBTAINED TO THE EFFECT THAT NO SUCH REGISTRATION IS
          REQUIRED OR (iii) A 'NO ACTION' LETTER OR ITS THEN
          EQUIVALENT HAS BEEN ISSUED BY THE STAFF OF THE SECURITIES
          AND EXCHANGE COMMISSION WITH RESPECT TO SUCH TRANSFER OR
          SALE."

               3.2.   Restricted Securities.  Each Investor understands that the
                      ---------------------                                     
Preferred Shares (and any Conversion Shares) will not be registered at the
Closing under the Securities Act for the reason that the sale provided for in
this Agreement is exempt pursuant to Section 4 of the Securities Act and that
the reliance of the Company on such exemption is predicated in part on such
Investor's representations set forth herein. Each Investor represents that it is
experienced in evaluating companies such as the Company, is able to fend for 
itself, has such knowledge and experience in financial and business matters as 
to be capable of evaluating the merits and risks of its investment, and has the 
ability to suffer the total loss of its investment. Each Investor is an 
accredited investor within the meaning of Rule 501 of Regulation D promulgated 
under the Securities Act. Such Investor was not formed solely for the purpose of
investing in the Company. Each Investor further represents that it has had 
access during the course of the transaction and prior to its purchase of the 
Preferred Shares to such information relating to the Company as it has desired 
and that it has had the opportunity to ask questions of and receive answers from
the Company concerning the terms and conditions of the offering and to obtain 
additional information (to the extent the Company possessed such information or 
could acquire it without unreasonable effort or expense) necessary to verify the
accuracy of any information furnished to it or to which it had access.

          Each Investor understands that the Preferred Shares (and any 
Conversion Shares) may not be sold, transferred or otherwise disposed of without
registration under the Securities Act or an exemption therefrom and that in the 
absence of an effective registration statement covering the Preferred Shares (or
the Conversion Shares) or an available exemption from registration under the 
Securities Act, the Preferred Shares (and any Conversion Shares) must be held
indefinitely. The benefits of Rule 144 promulgated under the Securities Act are
not presently available, the Company has not covenanted to make the benefits of
such Rule available, and the Company has no present plans to make the benefits
of such Rule available.

          4.   Affirmative Covenants of the Company.  The Company covenants and
               ------------------------------------                            
agrees with each Qualified Investor that as long as any Preferred Shares are
issued and outstanding:

               4.1.   Accounting System. It will maintain a system of accounting
                      -----------------

of income and retained earnings and cash flow for such fiscal year, setting
forth in each case in comparative form corresponding figures for the preceding
fiscal year and for the budget for the fiscal year just completed (provided,
however, that information as to the budgeted figures will not be audited), all
of which will fairly present the financial condition of the Company at the date
shown and the results of its operations for the 

                                      -12-
<PAGE>
 
period then ended. Such financial statements shall be accompanied by the report
thereon of nationally recognized independent public accountants to the effect
that such financial statements have been prepared in accordance with generally
accepted accounting principles applied on a basis consistent with prior years
(except as otherwise specified in such report). The Company will use its best
efforts to conduct its business so that such report of the independent public
accountants will not contain any qualifications as to the scope of the audit,
the continuance of the Company, or with respect to the Company's compliance with
generally accepted accounting principles consistently applied, except for
changes in methods of accounting in which such accountants concur.

                      (b)  It will furnish to each Qualified Investor, as soon

as at the end of such month and an unaudited statement of income and statement
of cash flows for such month and for the fiscal year to date, setting forth in
each case in comparative form the corresponding figures for the preceding year
and for the budget. All such reports shall be certified to by the chief
financial officer of the Company to fairly present the financial condition of
the Company at the date shown and the results of its operations for the period
then ended and to have been prepared in accordance with generally accepted
accounting principles for interim financial information consistently applied
except for normal year end adjustments. The reports for each calendar month
shall include a narrative discussion prepared by the Company describing the
business and operations of the Company during the preceding calendar month.

                      (c)  It will furnish to its Board of Directors as early as
practicable prior to the end of each fiscal year of the Company for its
approval, and promptly after obtaining such approval will furnish to each
Qualified Investor, an annual Business Plan for the Company as approved by the
Company's Board of Directors for (i) the succeeding fiscal year, containing
projections of profit and loss and cash flow for each month of such fiscal year
and ending balance sheets for each quarter of such fiscal year, and (ii) the
succeeding two fiscal years, 

                                      -13-
<PAGE>
 
containing projections of profit and loss, cash flow and ending balance sheets
for each of such years. Promptly upon preparation thereof, the Company will
furnish to each such holder any other budgets that the Company may prepare and
provide to the Board of Directors generally and any revisions of such previously
furnished budgets.

                      (d)  It will furnish to each Qualified Investor, promptly
after receipt, each audit response letter, accountant's management letter and
other reports submitted to the Company by its independent public accountants in
connection with an annual or interim audit of the books of the Company.

               4.3.   Certificates of Compliance. Concurrently with the
                      --------------------------
furnishing of the reports pursuant to Sections 4.2(a) and 4.2(b) hereof, it will
furnish to each recipient a certificate of an officer stating that the Company
is not in material default under, and has not materially breached, this
Agreement, or if any such default or breach exists, specifying the nature
thereof and what actions the Company has taken and proposes to take with respect
thereto. Concurrently with the furnishing of the reports pursuant to Section
4.2(a) hereof, the Company will cause to be furnished to each Qualified Investor
a statement of the independent public accountants of the Company to the effect
that they have caused the provisions of this Agreement to be reviewed and that
in the course of their audit of the Company nothing has come to their attention
to lead them to believe that any default hereunder exists or, if such is not the
case, specifying such default or possible default and the nature thereof. The
Company covenants that promptly after the occurrence of any material default
hereunder or any material default under or breach of any material agreement, it
will deliver to its Board of Directors a certificate of an officer specifying in
detail the nature and period of existence thereof, and what actions the Company
has taken and proposes to take with respect thereto.

               4.4.   Other Reports and Inspection. It will furnish to each
                      ----------------------------
Qualified Investor, as soon as practicable after issuance, copies of any
financial statements or reports prepared by the Company for and furnished to its
stockholders or the Commission. It will furnish promptly to each Qualified
Investor such other documents, reports and financial data as such 

                                      -14-

holder may reasonably request to the extent such data is readily available. It
will, upon reasonable prior notice, make available to each such holder or such

compensation insurance and such other insurance with financially sound insurers
with respect to its properties and business of the kinds and in amounts similar
to those listed on Schedule 2.21 attached hereto.  The activities and operations
of the Company will be conducted in a manner so as to conform in all material
respects to all applicable provisions of such insurance policies.

               4.6.   Licenses. It will obtain and keep in full force and effect
                      --------
all licenses, permits and other authorizations from governmental authorities
which shall be necessary to the conduct of its business.

               4.7.   Material Changes.  It will promptly advise each Qualified

     8.   Registration Rights.
          ------------------- 

          8.1.    Required Registration.  If at any time following the third
                  ---------------------                                     
anniversary of the Closing Date the holders of at least 50% of the Registrable
Securities shall decide to sell or otherwise dispose of Registrable Securities
of the Company then owned by such holders, such holders may give written notice
to the Company of the proposed disposition, specifying the number of Registrable
Securities so to be sold or disposed of (which must include at least 50% of the
Registrable Securities) and requesting that the Company prepare and file a
registration statement under the Securities Act covering such Registrable
Securities.  The Company shall, within 10 days thereafter, give written notice
to the other holders of Registrable Securities of such request and each of the
other holders shall have the option, for a period of 10 days after receipt by it
of such notice from the Company, to include its Registrable Securities in such
registration statement.  The Company shall use its best efforts to cause an
appropriate registration statement (the "Registration Statement") covering such
Registrable Securities to be filed with the Commission and to become effective
as soon as reasonably practicable and to 

                                      -22-
<PAGE>
 
remain effective until the completion of the distribution of the Registrable
Securities to be offered or sold but not longer than 90 days after effectiveness
of the Registration Statement. (The holders whose Registrable Securities are
included in a Registration Statement are hereinafter referred to as the "Selling
Investors"). The Company shall not be obligated to file more than two
Registration Statements pursuant to the foregoing provisions of this Section
8.1. The Company shall bear all of the Costs and Expenses of the two
Registration Statements. In addition to the foregoing and without regard to
there first having been filed either of the two Registration Statements provided
for in the foregoing provisions of this Section 8.1, the holders of Registrable
Securities will be entitled to demand an unlimited number of Registration
Statements on Form S-3 or any successor form allowing substantial incorporation
by reference to Securities Exchange Act reports filed by the Company, but only
if the Company is eligible to use Form S-3 or such successor Form, at such
holders' Cost and Expense, provided however, that at least $500,000 in aggregate
sales price less underwriters discounts and commissions of Registrable
Securities are proposed to be sold pursuant thereto and no more than one such
Registration Statement is demanded in any twelve month period of time. A demand
for registration under this Section 8.1 will not count as such until it has
become effective and unless the holders of Registrable Securities are able to
register and sell at least 80% of the Registrable Securities included in such
Registration Statement; provided, however, that if the initiating holders
withdraw a request for registration before the Registration Statement becomes
effective, then the initiating holders at their option either shall (i) bear the
Costs and Expenses thereof pro rata on the basis of the number of shares
requested to be included therein or (ii) have such Registration Statement
applied to and counted as one of the two Registration Statements for which the
Company has agreed to bear the Costs and Expenses.

          8.2.   Procedure for Registration.  In connection with the filing of a
                 --------------------------                                     
Registration Statement pursuant to Section 8.1 hereof, and in supplementation
and not in limitation of the provisions hereof, the Company shall:

                                      -23-
<PAGE>
 
                 (a)  Notify the Selling Investors as to the filing of the
Registration Statement and of all amendments or supplements thereto filed prior
to the effective date of said Registration Statement; 

                 (b)  Notify the Selling Investors, promptly after the Company
shall receive notice thereof, of the time when said Registration Statement
became effective or when any amendment or supplement to any prospectus forming a
part of said Registration Statement has been filed;

                 (c)  Notify the Selling Investors promptly of any request by
the Commission for the amending or supplementing of such Registration Statement
or prospectus or for additional information;

                 (d)  Prepare and promptly file with the Commission and promptly
notify the Selling Investors of the filing of any amendments or supplements to
such Registration Statement or prospectus as may be necessary to correct any
statements or omissions if, at any time when a prospectus relating to the
Registrable Securities is required to be delivered under the Securities Act, any
event with respect to the Company shall have occurred as a result of which any
such prospectus or any other prospectus as then in effect would include an
untrue statement of a material fact or omit to state any material fact necessary
to make the statements therein not misleading; and, in addition, prepare and
file with the Commission, promptly upon the Selling Investors' written request,
any amendments or supplements to such Registration Statement or prospectus which
may be reasonably necessary or advisable in connection with the distribution of
the Registrable Securities;

                 (e)  Prepare, promptly upon request of the Selling Investors or
any underwriters for the Selling Investors, such amendment or amendments to such
Registration Statement and such prospectus or prospectuses as may be reasonably
necessary to permit compliance with the requirements of Section 10(a)(3) of the
Securities Act;

                 (f)  Advise the Selling Investors promptly after the Company
shall receive notice or obtain knowledge of the issuance of any stop order by
the Commission 

                                      -24-
<PAGE>
 
suspending the effectiveness of any such Registration Statement or amendment
thereto or of the initiation or threatening of any proceeding for that purpose,
and promptly use its best efforts to prevent the issuance of any stop order or
obtain its withdrawal promptly if such stop order should be issued;

                 (g)  Use its best efforts to qualify, as soon as reasonably
practicable, the Registrable Securities for sale under the securities or blue-
sky laws of such states and jurisdictions within the United States as shall be
reasonably requested by the Selling Investors; provided, that the Company shall
not be required in connection therewith or as a condition thereto to qualify to
do business, to become subject to taxation or to file a consent to service of
process generally in any of the aforesaid states or jurisdictions;

                 (h)  Furnish the Selling Investors, as soon as available,
copies of any Registration Statement and each preliminary or final prospectus,
or supplement or amendment required to be prepared pursuant hereto, all in such
quantities as the Selling Investors may, from time to time, reasonably request;
and

                 (i)  If requested by the Selling Investors, enter into an
agreement with the underwriters of the Registrable Securities being registered
containing customary provisions and reflecting the foregoing.

          8.3.   Incidental Registration.  If at any time the Company shall
                 -----------------------                                   
propose the filing of a Registration Statement on an appropriate form under the
Securities Act of any securities of the Company, otherwise than pursuant to
Section 8.1 hereof and other than a registration statement on Forms S-8 or S-4
or any equivalent form then in effect, then the Company shall give the holders
of Registrable Securities, XIST LTD. and Vanguard notice of such proposed
registration and shall include in any Registration Statement relating to such
securities all or a portion of the Registrable Securities and Common Stock then
owned by such holders, which such holders shall request (such holders to be
considered Selling Investors), by notice given by such holders to the Company
within 30 days after the giving of such notice by the Company, to be so
included.  In the event of the inclusion of Registrable Securities and Common

                                      -25-
<PAGE>
 
Stock pursuant to this Section 8.3, the Company shall bear all of the Costs and
Expenses of such registration; provided, however, that the Selling Investors
shall pay, pro rata based upon the number of Registrable Securities and Common
Stock included therein, the underwriters discounts and compensation.  In the
event the distribution of securities of the Company covered by a Registration
Statement referred to in this Section 8.3 is to be underwritten, then the
Company's obligation to include Registrable Securities and Common Stock in such
Registration Statement shall be subject, at the option of the Company, to the
following further conditions:

          (a)  The distribution for the account of the Selling Investors shall
be underwritten by the same underwriters who are underwriting the distribution
of the securities for the account of the Company and/or any other persons whose
securities are covered by such Registration Statement, and the Selling Investors
will enter into an agreement with such underwriters containing customary
provisions;

          (b)  If the underwriting agreement entered into with the aforesaid
underwriters contains restrictions upon the sale of securities of the Company,
other than the securities which are to be included in the proposed distribution,
for a period not exceeding 150 days from the effective date of the Registration
Statement, then such restrictions will be binding upon the Selling Investors
and, if requested by the Company, the Selling Investors will enter into a
written agreement to that effect; and

          (c)  If the underwriters state in writing that they are unwilling to
include any or all of the Selling Investors' securities in the proposed
underwriting because such inclusion will materially interfere with the orderly
sale and distribution of the securities being offered by the Company, then the
number of Selling Investors' securities to be included will be reduced pro rata
on the basis of the number of shares owned by such holders, or there will be no
inclusion of Selling Investors' securities in the registration statement and
proposed distribution, in accordance with such statement by the underwriters.

      8.4. Indemnification by the Company.  The Company will indemnify and
           ------------------------------                                 
hold harmless each Selling Investor, any underwriter (as defined in the
Securities Act) for

                                      -26-
<PAGE>
 
such Selling Investor, each partner, officer and director of such Selling
Investor, and each person, if any, who controls such Selling Investor or such
underwriter within the meaning of the Securities Act (but, in the case of an
underwriter or a controlling person, only if such underwriter or controlling
person indemnifies the persons mentioned in subdivision (b) of Section 8.5
hereof in the manner set forth therein), against any losses, claims, damages or
liabilities, joint or several, to which such Selling Investor or any such
underwriter, partner, officer, director or controlling person becomes subject,
under the Securities Act or otherwise, insofar as such losses, claims, damages
or liabilities (or actions in respect thereof) are caused by any untrue
statement or alleged untrue statement of any material fact contained in any
preliminary prospectus (if used prior to the effective date of the Registration
Statement and not corrected or supplied in the final prospectus for such
Registration Statement), or contained, on the effective date thereof, in any
Registration Statement under which Registrable Securities were registered under
the Securities Act, the prospectus contained therein, or any amendment or
supplement thereto, or arising out of or based upon the omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading; and the Company will
reimburse such Selling Investor and any such underwriter, partner, officer,
director or controlling person for any legal or other expenses reasonably
incurred by such Selling Investor, or any such partner, officer, director,
underwriter or controlling person in connection with investigating or defending
any such loss, claim, damage, liability or action; provided, however, that the
Company will not be liable to any such persons in any such case to the extent
that any such loss, claim, damage, liability or action arises out of or is based
upon any untrue statement or alleged untrue statement or omission or alleged
omission made in reliance upon and in conformity with information furnished to
the Company in writing by such person expressly for inclusion in any of the
foregoing documents.

      8.5. Indemnification by Selling Investors.  Each Selling Investor shall:
           ------------------------------------
           (a)  Furnish in writing all information to the Company concerning
itself and its holdings of securities of the Company as shall be required in
connection

                                      -27-
<PAGE>
 
with the preparation and filing of any Registration Statement covering any
Registrable Securities; and

           (b)  Indemnify and hold harmless the Company, each of its directors,
each of its officers who has signed a Registration Statement, each person, if
any, who controls the Company within the meaning of the Securities Act and any
underwriter (as defined in the Securities Act) for the Company, against any
losses, claims, damages or liabilities to which the Company or any such
director, officer, controlling person or underwriter may become subject under
the Securities Act or otherwise, insofar as such losses, claims, damages or
liabilities (or actions in respect thereof) are caused by any untrue or alleged
untrue statement of any material fact contained in any preliminary prospectus
(if used prior to the effective date of the Registration Statement) or contained
on the effective date thereof, in any Registration Statement under which
Registrable Securities were registered under the Securities Act, the prospectus
contained therein, or any amendment or supplement thereto, or arising out of or
based upon the omission or alleged omission to state therein a material fact
required to be stated therein or necessary to make the statements therein not
misleading; in each case to the extent, but only to the extent, that such untrue
statement or alleged untrue statement or omission or alleged omission was made
in reliance upon and in conformity with information furnished to the Company by
such Selling Investor expressly for inclusion in any of the foregoing documents,
and such Selling Investor shall reimburse the Company and any such underwriter,
officer, director or controlling person for any legal or other expenses
reasonably incurred by the Company or any such director, officer or controlling
person in connection with investigating or defending any such loss, claim,
damage, liability or action.  Notwithstanding the foregoing provisions of this
Section 8.5, no Selling Investor shall be required to indemnify the Company or
any such underwriter, officer, director or controlling persons for any amount in
excess of the amount of the proceeds received by such Selling Investor.

      8.6. Notification by Selling Investors.  Each Selling Investor and
           ---------------------------------                            
each other person indemnified pursuant to Section 8.4 hereof will, in the event
it receives notice of the

                                      -28-
<PAGE>
 
commencement of any action against it which is based upon an alleged act or
omission which, if proven, would result in the Company's having to indemnify it
pursuant to Section 8.4 hereof, promptly notify the Company, in writing, of the
commencement of such action and permit the Company, if the Company so notifies
such Selling Investor within 10 days after receipt by the Company of notice of
the commencement of the action, to participate in and to assume the defense of
such action with counsel reasonably satisfactory to such Selling Investor or
such other indemnified person, as the case may be; provided, however, that such
Selling Investor shall be entitled to retain its own counsel at the Company's
expense if they have defenses available to them which are not available to the
Company or if there exists a potential for conflict of interest between the
Company and such Selling Investor which would render such dual representation
impractical. The omission to notify the Company promptly of the commencement of
any such action shall not relieve the Company of any liability to indemnify such
Selling Investor or such other indemnified person, as the case may be, under
Section 8.4 hereof, except to the extent the Company shall suffer any loss by
reason of such failure to give notice and shall not relieve the Company of any
other liabilities which it may have under this or any other agreement.

      8.7. Notification by Company.  The Company agrees that, in the event
           -----------------------                                        
it receives notice of the commencement of any action against it which is based
upon an alleged act or omission which, if proven, would result in any Selling
Investor having to indemnify the Company pursuant to subdivision (b) of Section
8.5 hereof, the Company will promptly notify such Selling Investor in writing of
the commencement of such action and permit such Selling Investor, if such
Selling Investor so notifies the Company within 10 days after receipt by it of
notice of the commencement of the action, to participate in and to assume the
defense of such action with counsel reasonably satisfactory to the Company.  The
omission to notify such Selling Investor promptly of the commencement of any
such action will not relieve such Selling Investor of liability to indemnify the
Company under subdivision (b) of Section 8.5 hereof, except to the extent that
such Selling Investor suffers any loss by reason of such failure to give notice
and shall

                                      -29-
<PAGE>
 
not relieve such Selling Investor of any other liabilities which it may have
under this or any other agreement.

      8.8. Costs and Expenses.  As used in this Agreement, "Costs and
           ------------------                                        
Expenses" shall include all of the costs and expenses relating to the
Registration Statement involved, including but not limited to registration,
filing and qualification fees, blue-sky expenses, printing expenses, reasonable
fees and disbursements of counsel to the Company and counsel for the Selling
Investors as the Selling Investors may designate, provided, however, that no
more than one such counsel for the Selling Investors will be so designated on
any occasion, and accounting fees; provided however, that underwriting discounts
and commissions and reimbursable underwriters' expenses will be borne pro rata
by the holders of the securities included in the Registration Statement.

      8.9. Rule 144 Reporting.  After the Company becomes subject to the
           ------------------                                           
reporting requirements of Sections 13 or l5(d) of the Securities Exchange Act,
and with a view to making available the benefits of certain rules and
regulations of the Commission which may permit the sale of the Preferred Shares
or the Conversion Shares without registration, the Company agrees to:

          (a)  Cause public information with respect to the Company to be
available, as set forth in Rule 144 or any comparable rule or regulation under
the Securities Act, at all times;

          (b)  Use its best efforts to tile with the Commission in a timely
manner all reports and other documents required of the Company under the
Securities Act and the Securities Exchange Act; and

          (c)  To furnish to each holder of Registrable Securities forthwith
upon request a written statement by the Company as to its compliance with the
reporting requirements of said Rule 144 and of the Securities Act and the
Securities Exchange Act.

      9.  Expenses.

contemplated hereby are consummated, to pay on a pro rata basis based on the
proceeds received by each of them from the consummation of this Agreement and
the agreements attached as Exhibit G hereto, and save the Investors harmless
against liability for the payment of, the reasonable fees and expenses of

the negotiation, execution and consummation of this Agreement and the
transactions contemplated hereby, which fees and expenses will be paid promptly
after presentation of such counsel's statement, reasonably itemized as to hours
and dates worked, attorneys and other professionals performing services and
nature of the work on each such date.  The Company also agrees to pay, and save
the Investors harmless against liability for the payment of, (a) fees and
expenses (including without limitation, reasonable attorneys' fees) incurred
with respect to any amendments or waivers requested by the Company (whether or
not the same become effective) under or in respect of this Agreement and the
transactions contemplated hereby, (b) stamp and other transfer taxes which may
be payable in respect of the execution and delivery of this Agreement or the
issuance of the Preferred Shares or the Conversion Shares and (c) fees and
expenses (including, without limitation, reasonable attorneys' fees) incurred in
respect of the enforcement by the Investors of the rights granted to the
Investors under this Agreement and the transactions contemplated hereby.

          10.  Right of First Refusal.
               ---------------------- 
          (a)  The Company agrees that until there is a Public Offering of its
securities if it sells any New Securities it will offer to the Qualified
Investors the right to purchase additional shares of such New Securities of the
Company in accordance with, and subject to, the provisions of this Section
10(a).  The Company shall immediately notify the Qualified Investors of the
terms for the sale of such New Securities by the Company (the "Company's
Notice").  Each of the Qualified Investor wishing to purchase such New
Securities pursuant to the Company's Notice (hereinafter referred to as a
"Purchasing Party") shall notify the Company by written notice within 15 days
after receipt of the Company's Notice how many of such shares it 

                                      -31-

desires to purchase. Each Purchasing Party shall be entitled to purchase up to
that number of shares of New Securities specified in its notice which is equal
to a number of shares of New Securities which, when added to the Conversion
Shares then held by such Investor (assuming conversion of all Preferred Shares),
is in the same proportion to the total number of shares of securities of the
Company then outstanding (assuming conversion of all convertible securities and
exercise of all outstanding options and including the New Securities to the
extent outstanding), as the number of Conversion Shares held by such Investor
(assuming conversion of all Preferred Shares) bears to the total number of
shares of securities of the Company outstanding immediately prior to the
issuance of any New Securities (assuming conversion of all convertible
securities and exercise of all outstanding options). If the Company later
changes the terms of the sale in any material respect, the Company shall first
reoffer such New Securities to the Investors pursuant to the procedure set forth
above. Any New Securities which are sold (or issued) by the Company otherwise
than for cash shall be offered to the Investors for an equivalent cash value as
determined by the Board of Directors of the Company in good faith.

          (b)  Whether or not the terms and conditions of a sale of New
Securities provide for the purchaser to have any registration rights, the
Company agrees with the Investors that in the event any Investor acquires any
New Securities pursuant to paragraph (a) above, such Investor may elect either
to (i) have such New Securities be deemed Registrable Securities for the
purposes of Section 8 hereof or (ii) have the registration rights provided in
such sale.

          (c)  The closing of the purchase of shares pursuant to this Section 10
shall occur at the principal office of the Company not later than 45 days after
the closing of the sale of New Securities, or at such other time as the
Purchasing Parties and the Company may mutually determine.  At the closing, the
Company shall deliver to each Purchasing Party, the certificate or certificates
representing such shares, free and clear of all liens and encumbrances
whatsoever (other than those imposed by this Agreement), and such Purchasing
Party shall pay to the Company, in cash or by delivery of a cashier's check, or
by wire transfer, the amount of the

                                      -32-
<PAGE>
 
purchase price for the shares of New Securities purchased by such Purchasing
Party pursuant to this Section 10.

      11. Conduct Prior to the Closing Date.
          --------------------------------- 

          The Investors, their counsel, accountants, employees or other
representatives may, prior to the Closing Date, make such investigations of the
properties, plants and operations of the Company and such audit of the financial
condition of the Company for such purposes as it deems necessary or advisable in
connection with the transactions contemplated hereby; such investigation shall
not, however, affect the representations and warranties of the Company
hereunder.  Prior to the Closing Date, the Company agrees to permit the
Investors and their counsel, accountants, employees or other representatives to
have, after the date hereof and upon reasonable advance notice, full access
during normal business hours to the premises and to all books and records of the
Company and the Investors shall have the right to make copies thereof and
excerpts therefrom, and the Company will furnish the Investors with such
financial and operating data and other information with respect to the business
and properties of the Company as is otherwise readily available and as the
Investors may, from time to time, reasonably request.  Prior to the Closing
Date, the Company agrees to permit the Investors and their counsel, accountants,
employees or other representatives to communicate with and visit suppliers,
customers and others having business relations with the Company.  The Company
acknowledges that the rights set forth in this Section 11 are essential to the
Investors as a means of evaluating the assets and business of the Company and
agree that in no event will they make any claim of any kind as a result of the
exercise by the Investors of such rights and hereby waive any and all rights
they may have to make such claims.

      12. No Brokers.
          ---------- 

          Each of the Company, on the one hand, and the Investors, on the other
hand, represents and warrants to the other that there was no broker or finder
connected with this Agreement or the transactions contemplated hereby.  In the
event of a claim by any broker or finder based upon his or her representing or
being retained by the Investors, the Investors agree

                                      -33-
<PAGE>
 
to indemnify and save harmless the Company in respect of such claim. In the

being retained by the Company the Company agrees to indemnify and save harmless
the Investors in respect of such claim.

exhibit, schedule or certificate delivered in connection herewith shall survive

of six months from the Closing Date.  If the Company shall be required to file a
report with the Commission pursuant to Section 13(a) or 15(d) of the Securities
Exchange Act by reason of the Company having registered any of its securities
pursuant to Section 12 of the Securities Exchange Act or Section 5 of the
Securities Act (a "Reporting Event") then the Company shall be under no further
obligation to perform the covenants contained in Sections 4 and 5 hereof, except
for the covenants contained in Sections 4.1, 4.8, 4.11 and 5.6 (second sentence)
hereof which shall survive the Reporting Event.

The Company hereby represents and warrants to the Investors as follows:

          2.1. Organization.  The Company is a corporation duly organized,
               ------------

list of the holders of all issued and outstanding equity securities of the
Company on the date hereof, including the number of securities owned by each
such holder, is set forth on Schedule 2.3 attached hereto.  Except pursuant to

indirectly convertible into or exchangeable or exercisable for any capital stock
of the Company.

          2.4. Compliance with Other Instruments.  The Company is not in
               ---------------------------------                        
violation of this Certificate of Incorporation or By-Laws.  Neither the sale of
the Preferred Shares (or the issuance and delivery of the Conversion Shares),
the execution and delivery of this Agreement, nor the fulfillment of the terms
set forth in this Agreement and the consummation of the transactions
contemplated by this Agreement, will:  (i) conflict with or constitute a breach
of, or constitute a default under or an event which, with or without notice or
lapse of time or each, would be a breach of or default under or violation of the
Certificate of Incorporation or By-Laws of the Company or would be a breach of
or default under or violation of any material agreement, document, indenture,
mortgage or other instrument or undertaking by which the Company is bound or to
which any of its properties are subject, or would be a material violation of any
law, administrative regulation, judgment, order or decree applicable to the
Company; (ii) result in the creation or imposition of any material lien, charge
or encumbrance upon any property or assets of the Company; (iii) result in the
loss of any material license, certificate, legal privilege or legal right
enjoyed or possessed by the Company; (iv) give any party to any material
agreement to which the Company is a party a right of termination; or (v) except

provided for in this Agreement, require the consent of any other person or
entity under any agreement, indenture, mortgage, document or other instrument or
undertaking by which the Company is bound or to which any of its properties are
subject.

          2.5. Authorization.  The Company has the full corporate power and
               -------------                                               
authority to enter into this Agreement and to perform all of its obligations
hereunder.  The execution, delivery and performance of the terms of this
Agreement by the Company have been duly authorized by all necessary corporate
action.  This Agreement constitutes a legal, valid and binding obligation of the
Company enforceable in accordance with its terms.  The Company, in light of its
business or proposed business, does not require any consent, approval,
authorization or order of, or declaration, filing or registration with, any
court or governmental or regulatory agency or board in connection with the
execution and delivery of this Agreement and the consummation of the
transactions contemplated hereby.

          2.6. Compliance with the Securities Act.  Based upon the
               ----------------------------------                 
representations of the Investors set forth herein, and assuming the truth of
such representations, the offer, sale and issuance of the Preferred Shares (and
the issuance and delivery of the Conversion Shares) are exempt from the
registration requirements of the Securities Act of 1933.

          2.7. Reservation of Common Stock.  The Company shall reserve and keep
               ---------------------------                                     
available out of its authorized but unissued Common Stock the number of shares
of Common Stock required for issuance upon the conversion of all of the
Preferred Shares (including any additional shares of Common Stock which may
become so issuable by reason of the operation of anti-dilution provisions of the
Preferred Shares).

     3.   Representations, Warranties and Covenants of the Investors.  Each
          ----------------------------------------------------------       
Investor hereby severally represents and warrants to, and agrees with, the
Company as follows:

                                       4
<PAGE>
 
          3.1. Investment Intent.  Each Investor is acquiring the Preferred
               -----------------                                           
Shares (and any Conversion Shares) for its own account and not with a present
view to, or for sale in connection with, any distribution thereof in violation
of the Securities Act of 1933.  Each Investor consents to the placement of the
following legend on each certificate representing the Preferred Shares and on
each certificate representing the Conversion Shares:

          "THE SHARES EVIDENCED BY THIS CERTIFICATE HAVE NOT BEEN
          REGISTERED UNDER THE SECURITIES ACT OF 1933 AND MAY NOT BE
          TRANSFERRED OR SOLD UNLESS (i) A REGISTRATION STATEMENT
          UNDER SUCH ACT IS THEN IN EFFECT WITH RESPECT THERETO, (ii)
          A WRITTEN OPINION FROM COUNSEL FOR THE ISSUER OF MESSRS.
          STROOCK & STROOCK & LAVAN OR OTHER COUNSEL FOR THE HOLDER
          REASONABLY ACCEPTABLE TO THE ISSUER HAS BEEN OBTAINED TO THE
          EFFECT THAT NO SUCH REGISTRATION IS REQUIRED OR (iii) A 'NO
          ACTION' LETTER OR ITS THEN EQUIVALENT HAS BEEN ISSUED BY THE
          STAFF OF THE SECURITIES AND EXCHANGE COMMISSION WITH RESPECT
          TO SUCH TRANSFER OR SALE."

          3.2. Restricted Securities. Each Investor understands that the
               ---------------------
Preferred Shares (and any Conversion Shares) have not been registered under the
Securities Act of 1933 for the reason that the sale provided for in this
Agreement is exempt pursuant to Section 4 of the Securities Act of 1933 and that
the reliance of the Company on such exemption is predicated in part on such
Investor's representations set forth herein. Each Investor represents that it is
experienced in evaluating companies such as the Company, is able to fend for
itself, has such knowledge and experience in financial and business matters as
to be capable of evaluating the merits and risks of its investment, and has the
ability to suffer the total loss of its investment. Such Investor was not formed
solely for the purpose of investing in the Company. Each Investor further
represents that it has had access during the course of the transaction and prior
to its purchase of the Preferred Shares to such information relating to the
Company as it has desired and that it has had 

                                       5
<PAGE>
 
the opportunity to ask questions of and receive answers from the Company
concerning the terms and conditions of the offering and to obtain additional
information (to the extent the Company possessed such information or could
acquire it without unreasonable effort or expense) necessary to verify the
accuracy of any information furnished to it or to which it had access.

     Each Investor understands that the Preferred Shares (and any Conversion
Shares) may not be sold, transferred or otherwise disposed of without
registration under the Securities Act of 1933 or an exemption therefrom and that
in the absence of an effective registration statement covering the Preferred
Shares (or the Conversion Shares) or an available exemption from registration
under the Securities Act of 1933, the Preferred Shares (and any Conversion
Shares) must be held indefinitely.  The benefits of Rule 144 promulgated under
the Securities Act of 1933 are not presently available, the Company has not
covenanted to make the benefits of such Rule available, and the Company has no
present plans to make the benefits of such Rule available.

     4.  Deliveries of the Company.  On May 7, 1991, as a condition to the
         -------------------------                                        
Investors' obligation to pay the purchase price, the Company will deliver to the

fulfillment of the terms set forth in 

                                      -5-

Agreement, will: (i) conflict with or constitute a breach of, or constitute a
default under or an event which, with or without notice or lapse of time or
each, would be a breach of or default under or violation of the Certificate of
Incorporation or By-Laws of the Company or would be a breach of or default under
or violation of any material agreement, document, indenture, mortgage or other
instrument or undertaking by which the Company is bound or to which any of its
properties are subject, or would be a material violation of any law,
administrative regulation, judgment, order or decree applicable to the Company;
(ii) result in the creation or imposition of any material lien, charge or
encumbrance upon any property or assets of the Company; (iii) result in the loss
of any material license, certificate, legal privilege or legal right enjoyed or
possessed by the Company; (iv) give any party to any material agreement to which

Agreement by the Company have been duly authorized by all necessary corporate
action. This Agreement constitutes a legal, valid and binding obligation of the

and keep available out of its authorized but unissued Common Stock the number of
shares of Common Stock required for issuance upon the conversion of all of the
Preferred Shares and Exercise Shares (including any additional shares of Common
Stock which may become so issuable by reason of the operation of anti-dilution
provisions of the Preferred Shares and the Exercise Shares).

               2.8.   Litigation.  Except as set forth on Schedule 2.8 attached
                      ----------                                               
hereto, there is not now pending, and to the best knowledge of the Company there
is not threatened in writing, any litigation, action, suit or proceeding:  (i)
to which the Company is or will be a party in or before or by any court or
governmental or regulatory agency or body; or (ii) to which any of the officers
or employees of the Company is or will be a party in or before or by any court

person of his or her employment with any of such person's former employers.  In

order of any court, governmental department, commission, agency, instrumentality
or arbitrator outstanding against the Company having any material adverse effect
on the business or proposed business or operations, properties, assets or
condition, financial or otherwise, of the Company.

               2.9.   Compliance with Law.  The Company is in compliance in all
                      -------------------                                      
material respects with all applicable statutes and regulations of the United
States and of all states, municipalities and agencies in respect of the conduct
of its business.

               2.10.  Financial Statements.  Attached hereto as Schedule 2.10
                      --------------------
are the audited balance sheets of the Company at April 30, 1991, and the related

including the notes thereto, of the Company for the periods then ended, and the

statements of income for the period then ended. The financial statements
referred to above have been prepared in conformity with generally accepted
accounting principles consistently applied subject in the case of the interim
statements to normal year-end audit adjustments, and each balance 

                                      -7-
<PAGE>
 
sheet fairly presents the financial condition of the Company as of its date and
each statement of income fairly presents the results of operations of the
Company for the period covered thereby.

         3.    Representations, Warranties and Covenants of the Investors.  Each
               -----------------------------------------------------------      
Investor hereby severally represents and warrants to, and agrees with, the
Company as follows effective as of the delivery of the Purchase Price and the
exercise of the Warrants:

               3.1.   Investment Intent.  Each Investor is acquiring the
                      ------------------                                
Securities and Exercise Shares (and any Conversion Shares) for its own account
and not with a present view to, or for sale in connection with, any distribution
thereof in violation of the Securities Act of 1933.  Each Investor consents to
the placement of the following legend on each certificate representing the
Preferred Shares, on each certificate representing the Exercise Shares, on each
certificate representing the Conversion Shares and/or each Warrant:

         "THE SECURITIES EVIDENCED HEREBY HAVE NOT BEEN REGISTERED
         UNDER THE SECURITIES ACT OF 1933 AND MAY NOT BE TRANSFERRED
         OR SOLD UNLESS (i) A REGISTRATION STATEMENT UNDER SUCH ACT IS
         THEN IN EFFECT WITH RESPECT THERETO, (ii) A WRITTEN OPINION
         FROM COUNSEL FOR THE ISSUER OR MESSRS. STROOCK & STROOCK &
         LAVAN OR OTHER COUNSEL FOR THE HOLDER REASONABLY ACCEPTABLE
         TO THE ISSUER HAS BEEN OBTAINED TO THE EFFECT THAT NO SUCH
         REGISTRATION IS REQUIRED OR (iii) A 'NO ACTION' LETTER OR ITS
         THEN EQUIVALENT HAS BEEN ISSUED BY THE STAFF OF THE
         SECURITIES AND EXCHANGE COMMISSION WITH RESPECT TO SUCH
         TRANSFER OR SALE."

               3.2.   Restricted Securities.  Each Investor understands that the
                      ----------------------
Securities and Exercise Shares (and any Conversion Shares) have not been
registered under the Securities Act of 1933 for the reason that the sale
provided for in this Agreement is exempt pursuant to Section 4 of the Securities
Act of 1933 and that the reliance of the Company on such exemption is predicated
in part on such Investor's representations set forth herein.  Each Investor
represents that it is experienced in evaluating companies such as the Company,
is able to fend for itself, has such knowledge and experience in financial and
business matters as to be capable of evaluating the 

                                      -8-
<PAGE>
 
merits and risks of its investment, and has the ability to suffer the total loss
of its investment. Such Investor was not formed solely for the purpose of
investing in the Company. Each Investor further represents that it has had
access during the course of the transaction and prior to its purchase of the
Securities and Exercise Shares to such information relating to the Company as it
has desired and that it has had the opportunity to ask questions of and receive
answers from the Company concerning the terms and conditions of the offering and
to obtain additional information (to the extent the Company possessed such
information or could acquire it without unreasonable effort or expense)
necessary to verify the accuracy of any information furnished to it or to which
it had access.

         Each Investor understands that the Securities and Exercise Shares (and
any Conversion Shares) may not be sold, transferred or otherwise disposed of
without registration under the Securities Act of 1933 or an exemption therefrom
and that in the absence of an effective registration statement covering the
Securities and Exercise Shares (or the Conversion Shares) or an available
exemption from registration under the 1933 Act, the Securities and the Exercise
Shares (and any Conversion Shares) must be held indefinitely.  The benefits of
Rule 144 promulgated under the Securities Act of 1933 are not presently
available, the Company has not covenanted to make the benefits of such Rule
available, and the Company has no present plans to make the benefits of such
Rule available.

         4.    Deliveries of the Company.  On the Closing Date, as a condition
               -------------------------

1.2 hereof, the Company will deliver to the Investors executing this Agreement
the following:

Investor representing the Preferred Shares purchased by such Investor in

the Company that the representations and warranties in Section 2 are true and
correct as of the Closing Date; and

               (g)    a copy of the Certificate of Amendment and the Series D
Certificate.

         5.    Deliveries of the Company Upon Supplemental Closing.  As a
               ------------------------------------------- -------       
condition to the obligations of the Supplemental Investors participating in the
Supplemental Closing to pay the Purchase Price for the Supplemental Securities
purchased in the Supplemental Closing, the Company will deliver to the
Supplemental Investors a stock certificate registered in the name of each such
Supplemental Investor representing the Preferred Shares purchased by such

and any consents under the 1989 Agreement requiring the consent of the holders
of a majority of the Series A Stock, the Preferred Shares sold hereunder and the
Exercise Shares issuable upon exercise of the Warrants will participate pari
passu as a single class with the shares of the Series A Stock sold under the
1989 Agreement and the shares of the Series B Stock sold under the 1991
Agreement on an as-converted to Common Stock basis. Section 14.8 of the 1989
Agreement is hereby amended to include as Registrable Securities all Series B

to this Agreement or upon exercise of the Warrants. The Investors that are
holders of Series A Stock and Series B Stock, on behalf of themselves as holders

Stockholders' Agreement dated as of June 1, 1989 by and among the Company and
its shareholders, as amended (the "Stockholders' Agreement"), hereby agrees to

if such Investor was a Shareholder as defined in the Stockholders' Agreement.

               (d)    Pursuant to Section 14 of the Stockholders' Agreement, the
Investors, constituting the holders of a majority of the Company's outstanding
Preferred Stock and the holders of at least 60% of the Company's outstanding
Common Stock, amend the Stockholders' Agreement to:  (i) add the following to
the last sentence of Section 7 thereof: "and of that certain 1992 Preferred

default in the performance of any material obligation, agreement, instrument or
undertaking to which it is a party or by which it is bound. The Company is not
in violation of its Certificate of Incorporation or By-Laws. Neither the sale of
the Preferred Shares (or the issuance and delivery of the Conversion Shares),
the execution and delivery of this Agreement, nor the fulfillment of the terms
set forth in this Agreement and the consummation of the transactions
contemplated by this Agreement, will: (i) conflict with or constitute a breach

lapse of time or each, would be a breach of or default under or violation of the
Certificate of Incorporation or By-Laws of the Company or would be a breach of
or default under or violation of any material agreement, document, indenture,
mortgage or other instrument or undertaking by which the Company is bound or to
which any of its properties are subject, or would be a material violation of any
law, administrative regulation, judgment, order or decree applicable to the

               -------------

hereunder.  The execution, delivery and performance of the terms of this
Agreement by the Company have been duly authorized by all necessary corporate
action.  This Agreement constitutes a legal, valid and binding obligation of the
Company enforceable in accordance with its terms.  The Company, in light of its
business or proposed business, does not require any consent, approval,
authorization or order of, or declaration, filing or registration with, any
court or governmental or regulatory agency or board in connection with the
execution and delivery of this Agreement and the consummation of the
transactions contemplated hereby.

          2.6. COMPLIANCE WITH THE SECURITIES ACT.  Based upon the

(including any additional shares of Common Stock which may become so issuable by
reason of the operation of anti-dilution provisions of the Preferred Shares).

          2.8. LITIGATION.  Except as set forth on Schedule 2.8 attached hereto,
               ----------

threatened in writing, any litigation, action, suit or proceeding:  (i) to which
the Company is or will be a party in or before or by any court or governmental

of the Company is or will be a party in or before or by any court or
governmental or regulatory agency or body, concerning termination by such person
of his or her employment with any of such person's former employers.  In

order of any court, governmental department, commission, agency, instrumentality
or arbitrator outstanding against the Company having any material adverse effect
on the business or proposed business or operations, properties, assets or
condition, financial or otherwise, of the Company.

audited balance sheets of the Company at April 30, 1992, and the related

including the notes thereto, of the Company for the periods then ended, and the
unaudited balance sheet of the Company at April 30, 1993 and the related
statements of income for the period then ended.  The financial statements
referred to above have been prepared in conformity with generally accepted
accounting principles consistently applied subject in the case of the interim
statements to normal year-end audit adjustments, and each balance sheet fairly
presents the financial condition of the Company as of its date and each
statement of income fairly presents the results of operations of the Company for
the period covered thereby.

     3.   REPRESENTATIONS, WARRANTIES AND COVENANTS OF THE INVESTORS.  Each
          ----------------------------------------------------------       
Investor hereby severally represents and warrants to, and agrees with, the
Company as follows effective as of the delivery of the Purchase Price:

          3.1.   INVESTMENT INTENT.  Each Investor is acquiring the Preferred
                 -----------------                                           
Shares (and any Conversion Shares) for its own account and not with a present
view to, or for sale in connection with, any distribution thereof in violation
of the Securities Act of 1933.  Each Investor consents to the placement of the
following legend on each certificate representing the Preferred Shares and on
each certificate representing the Conversion Shares:

          "THE SECURITIES EVIDENCED HEREBY HAVE NOT BEEN REGISTERED UNDER THE
          SECURITIES ACT OF 1933 AND MAY NOT BE TRANSFERRED OR SOLD UNLESS (i) A
          REGISTRATION STATEMENT UNDER SUCH ACT IS THEN IN EFFECT WITH RESPECT
          THERETO, (ii) A 

                                       4
<PAGE>
 
          WRITTEN OPINION FROM COUNSEL FOR THE ISSUER OR COUNSEL FOR THE HOLDER
          REASONABLY ACCEPTABLE TO THE ISSUER HAS BEEN OBTAINED TO THE EFFECT
          THAT NO SUCH REGISTRATION IS REQUIRED OR (iii) A 'NO ACTION' LETTER OR
          ITS THEN EQUIVALENT HAS BEEN ISSUED BY THE STAFF OF THE SECURITIES AND
          EXCHANGE COMMISSION WITH RESPECT TO SUCH TRANSFER OR SALE."

          3.2. RESTRICTED SECURITIES.  Each Investor understands that the
               ---------------------                                     
Preferred Shares (and any Conversion Shares) have not been registered under the
Securities Act of 1933 for the reason that the sale provided for in this
Agreement is exempt pursuant to Section 4 of the Securities Act of 1933 and that
the reliance of the Company on such exemption is predicated in part on such
Investor's representations set forth herein.  Each Investor represents that it
is experienced in evaluating companies such as the Company, is able to fend for
itself, has such knowledge and experience in financial and business matters as
to be capable of evaluating the merits and risks of its investment, and has the
ability to suffer the total loss of its investment.  Such Investor was not
formed solely for the purpose of investing in the Company.  Each Investor
further represents that it has had access during the course of the transaction
and prior to its purchase of the Preferred Shares to such information relating
to the Company as it has desired and that it has had the opportunity to ask
questions of and receive answers from the Company concerning the terms and
conditions of the offering and to obtain additional information (to the extent
the Company possessed such information or could acquire it without unreasonable
effort or expense) necessary to verify the accuracy of any information furnished
to it or to which it had access.

     Each Investor understands that the Preferred Shares (and any Conversion
Shares) may not be sold, transferred or otherwise disposed of without
registration under the Securities Act of 1933 or an exemption therefrom and that
in the absence of an effective registration statement covering the Preferred
Shares (or the Conversion Shares) or an available exemption from registration
under the 1933 Act, the Preferred Shares (and any Conversion Shares) must be
held indefinitely.  The benefits of Rule 144 promulgated under the Securities
Act of 1933 are not presently available, the Company has not covenanted to make
the benefits of such Rule available, and the Company has no present plans to
make the benefits of such Rule available.

     4.   DELIVERIES OF THE COMPANY.  On the Closing Date, as a condition to the

and (iii) provide that the definition of "Securities" includes all securities

                            1993 STOCK OPTION PLAN
                            ----------------------
                        (as adopted September 10, 1993)


SECTION 1:    PURPOSE OF THE PLAN

This 1993 Stock Option Plan is intended to continue the established policy of
TSI International Software Ltd. ("Company") of encouraging ownership of its
Common Stock by selected persons and of providing incentives for them to
increase the productivity of the Company.  By extending to those selected
persons the opportunity to acquire proprietary interests in the Company and to
participate in its success, this Plan may be expected to benefit the Company and
its shareholders by making it possible for the Company to attract and retain the
best available talent and by rewarding those selected persons for their part in
increasing the value of the Company's stock.

SECTION 2:    PRIOR PLAN

Upon the effectiveness of the merger in which TSI International Ltd., a
Connecticut corporation ("TSI Connecticut") merges with and into the Company,
all options granted pursuant to the TSI Connecticut 1989 Stock Option Plan, as
amended, shall be assumed under this Plan, and shall be deemed granted under
this Plan for all purposes.

SECTION 3:    DEFINITIONS

As used herein, the following definitions shall apply:

     3.01  "Affiliate" shall mean any person or entity which controls, is
controlled by or is under common control with the Company, where "control" means
the ownership of more than fifty percent (50%) of the total voting power of the
outstanding stock of a corporation or of the outstanding ownership of a non-
corporate entity.

     3.02  "Board" shall mean the Board of Directors of the Company.

     3.03  "Code" shall mean the Internal Revenue Code of 1986, including any
amendments made thereto.

     3.04  "Committee" shall mean the Stock Option Committee of the Board of
Directors, if any, and shall otherwise mean the Board.
<PAGE>
 
     3.05  "Common Stock" shall mean the Common Stock, $.01 par value per share,
of the Company.

     3.06  "Company" shall mean TSI International Software Ltd.

     3.07  "Continuous Employment" with the Company or any Parent, Subsidiary or
Affiliate of the Company shall mean, in the case of an employee, continuous
regular employment by the Company or any Parent, Subsidiary or Affiliate of the
Company, or an uninterrupted chain of continuous regular employment by the
Company or any Parent, Subsidiary or Affiliate of the Company.  A leave of
absence granted in accordance with the Company's usual procedure which does not
operate to interrupt Continuous Employment for other benefits granted by the
Company shall not be considered a termination of employment nor an interruption
of Continuous Employment hereunder, and an employee who is granted such a leave
of absence shall be considered to be continuously employed during the period of
such leave.  In the case of an Optionee who is a director, independent
consultant, contractor or advisor, the Committee will have the discretion to
determine whether the Optionee is "continuously employed by the Company."

     3.08  "Formula Value" shall mean the sum of (I) the aggregate exercise
price of all In-the-Money Options to purchase Common Stock exercisable as of the
most recent fiscal year end plus (II) the greater of:

        (A) eighty percent (80%) of the annual sales of the Company for the
fiscal year of the Company most recently ended; or

        (B) the product of the Matrix Factor multiplied by the Company's net
profit before taxes for the twelve-month period ended on the last date of the
most recently ended fiscal year.

     3.09  "In-the-Money Options" shall mean outstanding options to purchase
Common Stock (whether granted pursuant to an employee stock option plan or
otherwise) as to which the exercise price per Share is less than the current
value of Common Stock per Share.  For purposes of the identification of "In-the-
Money Options" only, the current value of Common Stock per Share shall mean the
quotient of (I) the greater of:

        (A) eighty percent (80%) of the annual sales of the Company for the
Company's most recently ended fiscal year; or

        (B) the product of the Matrix Factor multiplied by the Company's net
profit before taxes for the twelve-month period ended on the last day of the
Company's most recently ended fiscal year,
<PAGE>
 
divided by (II) the Outstanding Shares as of the most recent fiscal year end.
- ----------

     3.10  "Matrix Factor" shall mean a percentage represented by the factor set
out in the matrix set forth in the addendum attached hereto.  For purposes of
determining "Earnings Growth" or "Sales Growth" for purposes of such matrix,
sales and net earnings of the Company for the most recently ended fiscal year
shall be compared to sales and net earnings of the Company for the second most
recently ended fiscal year.

          Net earnings, sales and net profits before taxes for each relevant
fiscal year, and annual sales of the Company for each fiscal year, shall be
determined in good faith by the Committee, on the basis of audited financial
statements of the Company prepared by the independent certified public
accountants then retained by the Company, to the extent available or expected to
be available within a reasonable time, or to the extent audited financial
statements are not and will not be so available, on unaudited financial
statements prepared according to generally accepted accounting principles
consistently applied to prior periods.

     3.11  "Option" shall mean a stock option granted pursuant to this Plan.

     3.12  "Optionee" shall mean a selected person who receives an Option.

     3.13  "Outstanding Shares" will mean the sum of the outstanding shares of
Common Stock plus all outstanding convertible preferred stock (on an as-if-
converted to Common Stock basis) plus all In-the-Money Options (on an as-if-
exercised basis).

     3.14  "Parent" means any corporation (other than the Company) in an
unbroken chain of corporations ending with the Company if, at the time of the
granting of the Option, each of such corporations other than the Company owns
stock possessing 50% or more of the total combined voting power of all classes
of stock in one of the other corporations in such chain.

     3.15  "Plan" shall mean this 1993 Stock Option Plan.

     3.16  "Share" shall mean a share of the Common Stock of the Company as
adjusted in accordance with Section 17 of this Plan.

     3.17  "Subsidiary" shall mean any corporation (other than the Company) in
an unbroken chain of corporations beginning with the Company if, at the time of
granting the Option, each of the corporations other than the last corporation in
the unbroken chain owns stock possessing 50% or more of the total combined
voting power of all classes of stock in one of the other corporations in such
chain.
<PAGE>
 
SECTION 4:    TYPES OF OPTIONS AND SHARES

Options to purchase Shares granted under this Plan may be either (a) incentive
stock options ("ISO's") within the meaning of Section 422A of the Code or (b)
non-qualified stock options ("NQSO's"), as designated at the time of grant.

SECTION 5:    STOCK RESERVED FOR THE PLAN

     5.01  Number of Shares.  The aggregate number of Shares, that may be issued
pursuant to Options granted under this Plan is 519,477 Shares, subject to
adjustment pursuant to the provisions of Section 16, plus any Shares that become
available through repurchases pursuant to Section 5.03, below.  At all times
during the term of this Plan, the Company shall reserve out of its authorized
but unissued Shares, or its treasury shares, such number of Shares as may be
issued upon the exercise of Options granted under this Plan.

     5.02  Termination or Expiration of Options.  If any Options granted under
this Plan shall for any reason terminate or expire without having been exercised
in full, the Shares not purchased under such Options shall be available for
future grant and purchase under this Plan.

     5.03  Repurchase of Stock.  Any Shares previously issued pursuant to this
Plan, and any Shares that were previously shares of the Company's Class C Common
Stock, that are subsequently repurchased pursuant to the Company's right to
repurchase stock, shall be available for future grant and purchase under this
Plan; provided that no such repurchased Shares may be made subject to ISO's
granted under this Plan.

SECTION 6:    ADMINISTRATION OF THE PLAN

     6.01  Committee.  The Board shall appoint a Stock Option Committee of
directors (the "Committee") to administer this Plan.  The Board may from time to
time appoint members of the Committee in substitution for or in addition to
members previously appointed to fill vacancies, however caused, in the
Committee.  Prior to such appointment, the entire Board shall act as the
"Committee."  No member of the Committee may participate in any respect
concerning the granting of an Option to such member.

     6.02  Administration by Committee.  The Committee shall have plenary
authority in its discretion (subject to the express provisions of this Plan): to
determine the purchase price of the Common Stock covered by each Option, the
selected persons to whom and the time or times at which Options shall be
granted, time or times at which Options granted hereunder shall become
exercisable, and the number of Shares to be covered by each Option; to interpret
this Plan; to prescribe, amend and rescind rules and regulations relating to
this Plan; to determine the terms (which need not be identical) of option
agreements executed and delivered under this Plan, including such terms and
provisions as shall be requisite in the judgment of the Committee to conform to
any change in any law or regulation applicable thereto; to accelerate the
exercisability 
<PAGE>
 
of any Option; to modify or amend any option agreement entered into pursuant
hereto; to execute on behalf of the Company any instrument required to
effectuate an Option grant; to ensure satisfaction of any withholding tax
obligation which may be imposed with respect to the grant or exercise of an
Option; and to make all other determinations deemed necessary or advisable for
the administration of the Plan. The Committee's determination on the foregoing
matters shall be conclusive. Upon the Committee's request, the President of the
Company shall make recommendations to the Committee as to the granting of
Options and any other determinations within the Committee's discretion.

SECTION 7:    ELIGIBILITY

Options may be granted to employees, officers, directors, consultants,
independent contractors and advisors (provided such consultants, contractors and
advisors render bona fide services not in connection with the offer and sale of
securities of the Company in a capital-raising transaction) of the Company or
any Parent, Subsidiary or Affiliate of the Company.  ISO's may be granted only
to employees (including officers and directors who are also employees) of the
Company or a Parent or Subsidiary of the Company.  The Committee in its sole
discretion shall select the Optionees.  An Optionee may be granted more than one
Option under this Plan.  The Company may also, from time to time, assume
outstanding options granted by another company, whether in connection with an
acquisition of such other company or otherwise, by either (i) granting an option
under this Plan in replacement of the option assumed by the Company, or (ii)
treating the assumed option as if it had been granted under this Plan if the
terms of such assumed option could be applied to an option granted under this
Plan.  Such assumption shall be permissible if the holder of the assumed option
would have been eligible to be granted an option hereunder if the other company
had applied the rules of this Plan to such grant.

SECTION 8:    FACTORS TO BE CONSIDERED IN GRANTING OPTIONS

In determining the selected persons to whom Options shall be granted, the terms
of the Option and the number of Shares to be covered by each Option, the
Committee shall take into account such factors as it shall deem relevant in
connection with accomplishing the purpose of this Plan.

SECTION 9:    GRANT AGREEMENT; CONSIDERATION

The Committee shall cause to be executed by any person receiving and accepting
the grant of an Option, a written option agreement in such form as the Committee
shall determine, specifying the terms and conditions of the Option (the
"Grant").  All Grants shall conform to the provisions of the Plan, but the
specific terms and conditions of each Option granted thereunder need not be the
same.  The Committee shall require such consideration for the granting of the
Option as it shall deem necessary or advisable.

SECTION 10:   OPTION PRICES
<PAGE>
 
The purchase price of Common Stock covered by each Option shall be determined by
the Committee, but shall not be less than 100% of the fair market value of the
Common Stock at the time the Option is granted unless the Committee determines,
with respect to NQSO's only, that a lower purchase price is advisable.  Any
determination of the fair market value or of the method of computing fair market
value of a share made by the Committee shall be final, binding and conclusive on
all parties.  In the absence of any provision by the Committee to the contrary,
the fair market value of the Share shall be (A) the Formula Value of the Company
divided by (B) the sum of (I) the Outstanding Shares plus (II) the maximum
aggregate number of shares of Common Stock which could be purchased by the
exercise of In-the-Money Options exercisable as of the most recent fiscal year
end.

SECTION 11:   TERM OF OPTIONS

Options shall be exercisable within the times or upon the events determined by
the Committee as set forth in the Grant; provided, however, that no Option shall
be exercisable after the expiration of ten (10) years from the date the Option
is granted, and provided further that no ISO granted to a holder of ten percent
(10%) or more of the Outstanding Shares shall be exercisable after the
expiration of five (5) years from the date the Option is granted.

SECTION 12:   EXERCISE OF OPTIONS

     12.01  When exercisable, the Committee shall have the discretion to
establish the vesting schedule for any Options granted under this Plan.

     In the event of a dissolution or liquidation of the Company, a merger in
which the Company is not the surviving corporation (except for a merger in which
the shareholders of the Company own or control a majority of the surviving
corporation's voting stock immediately following such merger), the acquisition
of all or substantially all of the Company's outstanding stock in which the
shareholders of the Company own or control less than a majority of the Company's
voting stock immediately following such acquisition, the sale of all or
substantially all of the assets of the Company, or any other transaction which
qualifies as a "corporate transaction" under Section 425(a) of the Code wherein
the shareholders of the Company give up all of their equity interest in the
Company, any or all outstanding Options shall, notwithstanding any contrary
terms of the Grant, accelerate and become exercisable in full at least twenty
(20) days prior to and shall expire on, (and, if the Company has reserved to
itself a right to repurchase shares issued upon exercise of Options at the
original purchase price of such shares, such right shall terminate upon), the
consummation of such dissolution, liquidation, merger, acquisition or sale of
assets at such times and on such conditions as the Committee shall determine.
The aggregate Fair Market Value (determined at the time an Option is granted) of
stock with respect to all ISOs held by an Optionee that first become exercisable
in the calendar year of such dissolution, liquidation, merger, sale of stock or
sale of assets may not exceed $100,000.  If the Fair Market Value of stock with
respect to which all ISOs are first exercisable in such calendar 
<PAGE>
 
year exceeds $100,000, the Options for the first $100,000 worth of stock to
become exercisable in that year shall be ISOs and the Options for the amount in
excess of $100,000 shall be NQSOs.

     Unless otherwise provided in the option agreement, a holder of an Option
may purchase all, or from time-to-time any part of, the Shares the right to
purchase which has accrued to him or her in accordance with the terms of this
Section.

     Except as provided in Sections 15 and 16, no Option may be exercised at any
time unless the holder thereof is then employed by the Company or a Parent,
Subsidiary or Affiliate of the Company.  In the case of an NQSO held by a
director, consultant, independent contractor or adviser, the Committee shall
determine, in its sole discretion, whether the Optionee is "employed by the
Company."  The holder of an Option shall have none of the rights of a
shareholder with respect to the Shares subject to Option until such Shares shall
have been registered on the transfer books of the Company in the name of the
person or persons exercising the Option upon the exercise of the option.

     12.02 Payment of Purchase Price.  Payment for the Shares may be made in
cash (by check) or, where approved by the Committee in its sole discretion at
the time of grant and where permitted by law: (i) the cancellation of
indebtedness of the Company to the Optionee; (ii) by waiver of compensation due
or accrued to Optionee for services rendered; (iii) by surrender of shares of
Common Stock of the Company that have been owned by the Optionee for more than
six (6) months (and which have been paid for within the meaning of SEC Rule 144)
or were obtained by the Optionee in the open public market having a Fair Market
Value equal to the exercise price of the Option; (iv) provided that a public
market for the Company's stock exists, through a "same day sale" commitment from
the Optionee and a broker-dealer that is a member of the National Association of
Securities Dealers (an "NASD Dealer") whereby the Optionee irrevocably elects to
exercise the Option and to sell a portion of the Shares so purchased to pay for
the exercise price and whereby the NASD Dealer irrevocably commits upon receipt
of such Shares to forward the exercise price directly to the Company; or (v) by
any combination of the foregoing.

     12.03 Withholding taxes.  Prior to issuance of the Shares upon exercise of
an Option, the Optionee shall pay or make adequate provision for any federal or
state withholding obligations of the Company, if applicable.  Where approved by
the Committee in its sole discretion, the Optionee may provide for payment of
withholding taxes upon exercise of the Option by requesting that the Company
retain Shares with a Fair Market Value equal to the minimum amount of taxes
required to be withheld.

     12.04 Notice of Election.  A person electing to exercise an Option shall
give written notice to the Company, as specified by the Committee, of his or her
election to exercise an Option and of the number of Shares such person has
elected to purchase, such notice to be accompanied by the instrument evidencing
such Option and any other documents required by the Committee or the Grant, and
shall at the time of such exercise tender the purchase price of the 
<PAGE>
 
Shares such person has elected to purchase. If the notice of election to
exercise is given by the executor or administrator of a deceased Optionee or by
the person or persons to whom the Option has been transferred under the
Optionee's will or the applicable laws of descent and distribution, the Company
will be under no obligation to deliver Shares pursuant to such exercise unless
and until the Company is satisfied that the person or persons giving such notice
is or are entitled to exercise the Option.

     12.05 Restrictive Agreement.  Any Common Stock purchased pursuant to an
Option granted under this Plan shall be held subject to such restrictions as the
Committee shall determine, in its sole discretion, are appropriate at the time
of grant of the Option.

SECTION 13:   ASSUMED OPTIONS

In the event the Company assumes an option granted by another Company, the terms
and conditions of such option shall remain unchanged (except the exercise price
and the number and nature of shares issuable upon exercise, which will be
adjusted appropriately pursuant to Section 425(c) of the Code).  In the event
the Company elects to grant a new option rather that assuming an existing option
(as specified in Section 7), such new option need not be granted at Fair Market
Value on the date of grant and may instead be granted with a similarly adjusted
exercise price.

SECTION 14:   NON-TRANSFERABILITY OF OPTIONS

An Option granted under this Plan shall not be transferable otherwise than by
will or the laws of descent and distribution, and an Option may be exercised,
during the lifetime of the Optionee, only by such Optionee.

SECTION 15:   TERMINATION OF EMPLOYMENT

     15.01 Right to Exercise Option.  If an Optionee ceases to be employed by
the Company or any Parent, Subsidiary or Affiliate of the Company for any reason
except death or disability, the Optionee may exercise such Optionee's Option to
the extent (and only to the extent) that it would have been exercisable upon the
date of termination, within three (3) months after the date of termination (or
such shorter time period as may be specified in the Grant), provided that, if
Optionee is an Insider and the Company is subject to Section 16(b) of the
Exchange Act, the Optionee's Option will be exercisable for a period of time
sufficient to allow such Optionee from having a matching purchase and sale under
Section 16(b), with any extension beyond three (3) months from termination of
employment deemed to be an NQSO, and provided further that in no event may an
Option be exercisable later than the expiration date of the Option.
<PAGE>
 
     15.02 Employment Relationship.  Options granted under this Plan shall not
be affected by change of duties or position so long as the Optionee continues to
be employed by or to have a similar relationship with the Company or any Parent,
Subsidiary or Affiliate of the Company; provided that the holder of an ISO must
remain an employee of the Company or a Parent or Subsidiary in order for such
Optionee's employment not to be deemed to have terminated as regards such ISO.
Retirement pursuant to any pension plan provided by the Company shall be deemed
to be a termination of employment for the purposes of this Section.  Nothing in
this Plan or in any Option granted pursuant to this Plan shall confer upon any
person employed by the Company or any Parent, Subsidiary or Affiliate of the
Company, any right to continue in the employ of the Company or any Parent,
Subsidiary or Affiliate of the Company or interfere with the right of the
Company to terminate such Optionee's employment or other relationship at any
time.

SECTION 16:   DEATH OF OPTIONEE

If an Optionee's employment or other relationship with the Company or any
Parent, Subsidiary or Affiliate of the Company is terminated because of the
death of the Optionee or disability of Optionee within the meaning of Section
22(e)(3) of the Code, such Optionee's Options may be exercised to the extent
(and only to the extent) that it would have been exercisable by the Optionee on
the date of termination, by the Optionee (or the Optionee's legal
representative) within twelve (12) months after the date of termination (or such
shorter time period as may be specified in the Grant), but in any event no later
than the expiration date of the Options.

SECTION 17:   ADJUSTMENTS UPON CHANGES IN CAPITALIZATION

In the event that the number of outstanding shares of Common Stock of the
Company is changed by the stock dividend, stock split, reverse stock split,
combination, re-classification or similar change in the capital structure of the
Company without consideration, or if a substantial portion of the assets of the
Company are distributed, without consideration in a spin-off or similar
transaction, to the shareholders of the Company, the number of Shares available
under this Plan and the number of Shares subject to outstanding Options and the
exercise price per share of such Option shall be proportionately adjusted,
subject to any required action by the Board or shareholders of the Company and
compliance with applicable securities laws; provided, however, that a fractional
share shall not be issued upon exercise of any Option and any fractions of a
Share that would have resulted shall either be cashed out at Fair Market Value
or the number of shares issuable under the Option shall be rounded up to the
nearest whole number, as determined by the Committee; and provided further that
the exercise price may not be decreased to below the par value, if any, for the
Shares.
<PAGE>
 
SECTION 18:   TIME OF GRANTING OPTIONS

Nothing contained in this Plan or in any resolution to be adopted by the Board
or the holders of securities of the Company shall constitute the granting of any
Option hereunder.  An Option granted pursuant to this Plan shall be deemed to
have been granted on the date on which the name of the recipient and price of
the Shares and the other terms of the Option are determined by the Committee.

SECTION 19:   TERMINATION AND AMENDMENT OF THE PLAN

Unless this Plan shall theretofore have been terminated as hereinafter in this
Section provided, no Option shall be granted hereunder after ten (10) years from
the date of the adoption hereof.  The Board may at any time prior to that date
terminate this Plan or make such modification or amendment of this Plan as it
shall deem advisable; provided, however, that no amendment may be made, without
the approval by the holders of the Company's shareholders, except as provided in
Section 16 hereof, which would (i) increase the maximum number of Shares for
which Options may be granted under this Plan, (ii) extend the period during
which an Option may be granted, or (iii) amend the requirements as to the class
of selected persons eligible to receive Options.  No termination, modification,
or amendment of this Plan or any Grant may, without consent of the Optionee to
whom an Option shall theretofore have been granted, adversely affect the rights
of such Optionee under such Option.

SECTION 20:   CONDITIONS UPON ISSUANCE OF SHARES

Shares of Common Stock shall not be issued with respect to an Option unless the
exercise of such Option and the issuance and delivery of such Shares pursuant
thereto shall comply with all relevant provisions of law, including, without
limitation, the Securities Act of 1933, as amended, the Securities Exchange Act
of 1934, as amended, the rules and regulations promulgated thereunder, the
requirements of any stock exchange upon which the Common Stock may then be
listed, the applicable state securities laws, and shall be further subject to
the approval of counsel for the Company with respect to such compliance.

As a condition to the exercise of an Option, the Company may require the person
exercising such Option to represent and warrant at the time of any such exercise
that the Common Stock is being purchased only for investment and without any
present intention to sell or distribute such Common Stock if, in the opinion of
counsel for the Company, such a representation is necessary or desirable under
any of the aforementioned relevant provisions of law.
<PAGE>
 
SECTION 21:   GOVERNMENT REGULATIONS

The Plan and the granting and exercise of Options hereunder, and the obligation
of the Company to sell and deliver Shares under such Options, shall be subject
to all applicable laws, rules and regulations.

SECTION 22:   EFFECTIVE DATE; SHAREHOLDER'S APPROVAL

          -----------------------
also agreeing to become a party to and be bound by that certain Stockholders'
Agreement dated as of June 1, 1989, as amended to the date hereof and as it may

understood the Plan and the Grant and agrees to abide by and be bound by their

as amended (the "1933 Act").

<PAGE>
 
     4.   Compliance with Securities Laws.  Optionee under- stands and
          -------------------------------
acknowledges that the Shares have not been regis- tered under the 1933 Act and
that, notwithstanding any other provision of the Grant to the contrary, the
exercise of any rights to purchase any Shares is expressly conditioned upon
compliance with the 1933 Act and all applicable state securities laws.  Optionee
agrees to cooperate with the Company to ensure compliance with such laws.  The
Shares are being issued under the 1933 Act pursuant to (the Company will check
the applicable box):

          [ ] the exemption provided by Rule 701;
          [ ] the exemption provided by Rule 504;
          [ ] Section 4(2) of the 1933 Act;
          [ ] other: _______________________.

     5.   Federal Restrictions on Transfer.  Optionee understands that the
          --------------------------------
Shares must be held indefinitely unless they are registered under the l933 Act
or unless an exemption from such registration is available and that the
certificate(s) representing the Shares will bear a legend to that effect.
Optionee understands that the Company is under no obligation to register the
Shares and that an exemption may not be available or may not permit Optionee to
transfer Shares in the amounts or at the times proposed by Optionee.

          (a)  Rule 144.  Optionee has been advised that Rule 144 promulgated
               --------
under the 1933 Act, which permits certain resales of unregistered securities, is
not presently available with respect to the Shares and, in any event, requires
that the Shares be paid for and then held for a minimum of two years before they
may be resold under Rule 144.  Prior to an initial public offering of the
Company's stock, "nonaffiliates" (i.e. persons other than officers, directors
and major shareholders of the Company) may resell only under Rule 144(k), which
requires that the Shares be paid for and held for a minimum of three years.
Rule 144(k) is not available to affiliates.

          (b)  Rule 701.  If the exemption relied upon for exercise of the
               --------
Shares is Rule 701, the Shares will become freely transferable, subject to
limited conditions regarding the method of sale, by nonaffiliates 90 days after
the first sale of common stock of the Company to the general public pursuant to
a registration statement filed with and declared effective by the SEC, subject
to any lengthier market standoff agreement contained in this Agreement or
entered into by the Optionee.  Affiliates must comply with the provisions (other
than the holding period requirements) of Rule 144.

     6.   State Law Restrictions on Transfer.  Optionee understands that
          ----------------------------------
transfer of the Shares may be restricted by applicable state laws and that the
certificate(s) representing the Shares may bear a legend to that effect.

                                      -3-

     7.   Company's Repurchase Option.
          ----------------------------

          (a) Termination Date.  Optionee shall be considered to be employed by
              ----------------
the Company for all purposes under this Section 7 if Optionee is an officer,
director or full-time employee of the Company or any Parent, Subsidiary or
Affiliate of the Company or if the Board of Directors determines that Optionee
is rendering substantial services as a part-time employee, consultant,
contractor or adviser to the Company or any Parent, Subsidiary or Affiliate of
the Company.  The Board of Directors of the Company shall have discretion to
determine whether Optionee has ceased to be employed by the Company or any
Parent, Subsidiary or Affiliate of the Company and the effective date on which
such employment terminated (the "Termination Date").
                                 ----------------

          (b) Repurchase Option.  In the event of Optionee's Termination Date
              -----------------

                                                  -------------------------
Optionee (or Optionee's personal representative) shall immediately offer the
Shares to the Company and the Company shall have a first right and option,
exercisable within thirty (30) days of such offer, to repurchase the Shares.

          (c) Repurchase Price.  The purchase price of each Share in such a case
              ----------------
shall be the "Formula Value per Share."  For purposes of this Section 7(c), the
Formula Value per Share shall mean the quotient obtained by dividing the
"Formula Value" (as defined in the Plan) by the "Outstanding Shares" (as defined
in the Plan.

          (d) Payment of Repurchase Price.  The purchase price in the case of
              ---------------------------
any purchase of Shares by the Company pursuant to this Section 7 shall be paid
in cash within thirty (30) days of acceptance of the offer described above or
within thirty (30) days of such time as audited or unaudited financial
statements setting out the information necessary to calculate the purchase price
are available, whichever is later, at which time the undersigned shall deliver
to the Company the stock certificate or certificates to be duly endorsed for

                       TSI INTERNATIONAL SOFTWARE, LTD.

                          1997 EQUITY INCENTIVE PLAN

                            As Adopted May 8, 1997


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

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

              2.1      Number of Shares Available.  Subject to Sections 2.2 and 
                       --------------------------  
18, the total number of Shares reserved and available for grant and issuance
pursuant to this Plan will be 750,000 Shares.  Subject to Sections 2.2 and 18,
Shares that: (a) are subject to issuance upon exercise of an Option but cease to
be subject to such Option for any reason other than exercise of such Option; (b)
are subject to an Award granted hereunder but are forfeited or are repurchased
by the Company at the original issue price; or (c) are subject to an Award that
otherwise terminates without Shares being issued will again be available for
grant and issuance in connection with future Awards under this Plan.  Any
authorized shares not issued or subject to outstanding grants under the
Company's 1993 Stock Option Plan (the "Prior Plan") on the Effective Date (as
defined below) and any shares that: (a) are issuable upon exercise of options
granted pursuant to the Prior Plan that expire or become unexercisable for any
reason without having been exercised in full or (b) are subject to an option
granted pursuant to the Prior Plan but are forfeited or are repurchased by the
Company at the original issue price; will no longer be available for grant and
issuance under the Prior Plan, but will be available for grant and issuance
under this Plan.  At all times the Company shall reserve and keep available a
sufficient number of Shares as shall be required to satisfy the requirements of
all outstanding Options granted under this Plan and all other outstanding but
unvested Awards granted under this Plan.  No Participant may receive (a)
Restricted Stock Awards, (b) Stock Bonus Awards, or (c) Options with an Exercise
Price below Fair Market Value for more than 100,000 Shares over the term of the
Plan, and the sum of such awards issued under this Plan may not exceed 200,000
Shares in the aggregate over the term of the Plan.

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

         3.   ELIGIBILITY.  ISO (as defined in Section 5 below) may be granted
              -----------                                                     
only to employees (including officers and directors who are also employees) of
the Company or of a Parent or Subsidiary of the Company.  All other Awards may
be granted to employees, officers, directors, consultants, independent
contractors and advisors of the Company or any Parent or Subsidiary of the
Company; provided such consultants, contractors and advisors render bona fide
         --------                                                            
services not in connection with the offer and sale of securities in a capital-
raising transaction.  No person will be eligible to receive more than 200,000
Shares in any calendar year under this Plan pursuant to the grant of Awards
hereunder, other than new employees of the Company or of a Parent or Subsidiary
of the Company (including new employees who are also officers and directors of
the Company or any Parent or Subsidiary of the Company) who are eligible to
receive up to a maximum of 300,000 Shares in the calendar year in which they
commence their employment.  A person may be granted more than one Award under
this Plan.

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

              4.1      Committee Authority.  This Plan will be administered by 
                       -------------------
the Committee or by the Board acting as the Committee.  Subject to the general
purposes, terms and conditions of this Plan, and to the direction of the Board,
the Committee will have full power to implement and carry out this Plan.
Without limitation, the Committee will have the authority to:

         (a)  construe and interpret this Plan, any Award Agreement and any
              other agreement or document executed pursuant to this Plan;

         (b)  prescribe, amend and rescind rules and regulations relating to
              this Plan;

         (c)  select persons to receive Awards;

         (d)  determine the form and terms of Awards;

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

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

         (g)  grant waivers of Plan or Award conditions;

         (h)  determine the vesting, exercisability and payment of Awards;

         (i)  correct any defect, supply any omission or reconcile any
              inconsistency in this Plan, any Award or any Award Agreement;

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

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

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

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

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

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

                                      -2-
<PAGE>
 
              5.3      Exercise Period.  Options may be exercisable within the 
                       ---------------  
times or upon the events determined by the Committee as set forth in the Stock 
Option Agreement governing such Option; provided, however, that no Option will 
                                        --------  -------   
be exercisable after the expiration of ten (10) years from the date the Option 
is granted; and provided further that no ISO granted to a person who directly or
                ----------------
by attribution owns more than ten percent (10%) of the total combined voting
power of all classes of stock of the Company or of any Parent or Subsidiary of
the Company ("Ten Percent Stockholder") will be exercisable after the expiration
of five (5) years from the date the ISO is granted. The Committee also may
provide for Options to become exercisable at one time or from time to time,
periodically or otherwise, in such number of Shares or percentage of Shares as
the Committee determines.

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

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

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

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

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

         (c)  Notwithstanding the provisions in paragraph 5.6(a) above, if a
              Participant is determined by the Board to have committed an act of
              theft, embezzlement, fraud, dishonesty or a breach of fiduciary
              duty to the Company or Subsidiary, neither the Participant, the
              Participant's estate nor such other person who may then hold the
              Option shall be entitled to exercise any Option with respect to
              any Shares whatsoever, after termination of service, whether or
              not after termination of service the Participant may receive
              payment from the Company or 

                                      -3-
<PAGE>
 
              Subsidiary for vacation pay, for services rendered prior to
              termination, for services rendered for the day on which
              termination occurs, for salary in lieu of notice, or for any other
              benefits. In making such determination, the Board shall give the
              Participant an opportunity to present to the Board evidence on his
              behalf. For the purpose of this paragraph, termination of service
              shall be deemed to occur on the date when the Company dispatches
              notice or advice to the Participant that his service is
              terminated.

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

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

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

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

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

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

              6.2      Purchase Price.  The Purchase Price of Shares sold 
                       -------------- 
pursuant to a Restricted Stock Award will be determined by the Committee and
will be at least 85% of the Fair Market Value of the Shares on the date the
Restricted Stock Award is granted, except in the case of a sale to a Ten Percent
Stockholder, in which case 

                                      -4-
<PAGE>
 
the Purchase Price will be 100% of the Fair Market Value. Payment of the
Purchase Price must be made in accordance with Section 8 of this Plan.

              6.3      Restrictions.  Restricted Stock Awards will be subject to
                       ------------                                             
such restrictions (if any) as the Committee may impose.  The Committee may
provide for the lapse of such restrictions in installments and may accelerate or
waive such restrictions, in whole or part, based on length of service,
performance or such other factors or criteria as the Committee may determine.

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

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

              7.2      Terms of Stock Bonuses.  The Committee will determine the
                       ----------------------                                   
number of Shares to be awarded to the Participant and whether such Shares will
be Restricted Stock.  If the Stock Bonus is being earned upon the satisfaction
of performance goals pursuant to a Performance Stock Bonus Agreement, then the
Committee will determine:  (a) the nature, length and starting date of any
period during which performance is to be measured (the "Performance Period") for
each Stock Bonus; (b) the performance goals and criteria to be used to measure
the performance, if any; (c) the number of Shares that may be awarded to the
Participant; and (d) the extent to which such Stock Bonuses have been earned.
Performance Periods may overlap and Participants may participate simultaneously
with respect to Stock Bonuses that are subject to different Performance Periods
and different performance goals and other criteria.  The number of Shares may be
fixed or may vary in accordance with such performance goals and criteria as may
be determined by the Committee.  The Committee may adjust the performance goals
applicable to the Stock Bonuses to take into account changes in law and
accounting or tax rules and to make such adjustments as the Committee deems
necessary or appropriate to reflect the impact of extraordinary or unusual
items, events or circumstances to avoid windfalls or hardships.

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

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

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

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

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

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

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

         (d)  by waiver of compensation due or accrued to the Participant for
              services rendered; provided, however, that the portion of the
              Purchase Price or Exercise Price equal to the par value of the
              Shares, if any, must be paid in cash;

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

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

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

         (f)  by any combination of the foregoing.

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

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

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

                                      -6-
<PAGE>
 
              9.2      Stock Withholding.  When, under applicable tax laws, a
                       -----------------                                     
Participant incurs tax liability in connection with the exercise or vesting of
any Award that is subject to tax withholding and the Participant is obligated to
pay the Company the amount required to be withheld, the Committee may in its
sole discretion allow the Participant to satisfy the minimum withholding tax
obligation by electing to have the Company withhold from the Shares to be issued
that number of Shares having a Fair Market Value equal to the minimum amount
required to be withheld, determined on the date that the amount of tax to be
withheld is to be determined.  All elections by a Participant to have Shares
withheld for this purpose will be made in accordance with the requirements
established by the Committee and be in writing in a form acceptable to the
Committee


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

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

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

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

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

         13.  CERTIFICATES.  All certificates for Shares or other securities
              ------------                                                  
delivered under this Plan will be subject to such stock transfer orders, legends
and other restrictions as the Committee may deem necessary or advisable,
including restrictions under any applicable federal, state or foreign securities
law, or any rules, regulations and other requirements of the SEC or any stock
exchange or automated quotation system upon which the Shares may be listed or
quoted.

         14.  ESCROW; PLEDGE OF SHARES.  To enforce any restrictions on a
              ------------------------                                   
Participant's Shares, the Committee may require the Participant to deposit all
certificates representing Shares, together with stock powers or other
instruments of transfer approved by the Committee, appropriately endorsed in
blank, with the Company or an agent designated by the Company to hold in escrow
until such restrictions have lapsed or terminated, and the Committee may cause a
legend or legends referencing such restrictions to be placed on the
certificates.  Any Participant who is permitted to execute a promissory note as
partial or full consideration for the purchase of Shares 

                                      -7-
<PAGE>
 
under this Plan will be required to pledge and deposit with the Company all or
part of the Shares so purchased as collateral to secure the payment of
Participant's obligation to the Company under the promissory note; provided,
                                                                   --------
however, that the Committee may require or accept other or additional forms of
- -------
collateral to secure the payment of such obligation and, in any event, the
Company will have full recourse against the Participant under the promissory
note notwithstanding any pledge of the Participant's Shares or other collateral.
In connection with any pledge of the Shares, Participant will be required to
execute and deliver a written pledge agreement in such form as the Committee
will from time to time approve. The Shares purchased with the promissory note
may be released from the pledge on a pro rata basis as the promissory note is
paid.

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

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

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

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

              18.1  Assumption or Replacement of Awards by Successor.  In the
                    ------------------------------------------------         
event of

         (a)  a dissolution or liquidation of the Company;

         (b)  a merger or consolidation in which the Company is not the
              surviving corporation (other than a merger or consolidation with a
                                     ----- ----                                 
              wholly-owned subsidiary, a reincorporation of the Company in a
              different jurisdiction, or other transaction in which there is no
              substantial change in the stockholders of the Company or their
              relative stock holdings and the Awards granted under this Plan are
              assumed, converted or replaced by the surviving corporation, which
              assumption will be binding on all Participants);

         (c)  a merger in which the Company is the surviving corporation but
              after which the stockholders of the Company immediately prior to
              such merger (other than any stockholder that merges with the
              Company in such merger, or which owns or controls another
              corporation that merges, with the Company in such merger) cease to
              own their shares or other equity interest in the Company;

         (d)  the sale of all or substantially all of the assets of the Company;
              or

                                      -8-
<PAGE>
 
         (e)  the acquisition, sale or transfer of more than 50% of the
              outstanding shares of the Company by tender offer or similar
              transaction;

any or all outstanding Awards will automatically vest for one additional year
and may also be assumed, converted or replaced by the surviving corporation (if
any), which assumption, conversion or replacement will be binding on all
Participants.  The Committee may, in its sole discretion, provide for additional
accelerated vesting of any or all Awards that are assumed, converted or replaced
by the surviving corporation.  In lieu of assuming, converting or replacing such
Awards, the surviving corporation may substitute equivalent Awards or provide
substantially similar consideration to Participants as was provided to
stockholders (after taking into account the existing provisions of the Awards
and the one year additional vesting).  The surviving corporation may also issue,
in place of outstanding Shares of the Company held by the Participant,
substantially similar shares or other property subject to repurchase
restrictions no less favorable to the Participant.  In the event such surviving
corporation (if any) refuses to assume or substitute Awards, as provided above,
pursuant to a transaction described in this Subsection 18.1, such Awards will
automatically vest for one additional year and will expire on such transaction
at such time and on such conditions as the Committee will determine, provided,
however, that the Committee may, in its sole discretion, provide for additional
accelerated vesting of any or all Awards granted pursuant to this Plan.  If such
accelerated options are not exercised prior to the consummation of the corporate
transaction, they shall terminate in accordance with the provisions of this
Plan.

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

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

         19.  ADOPTION AND STOCKHOLDER APPROVAL.  This Plan will become
              ---------------------------------                        
effective on the date on which the registration statement filed by the Company
with the SEC under the Securities Act registering the initial public offering of
the Company's Common Stock is declared effective by the SEC (the "Effective
Date"); provided, however, that if the Effective Date does not occur on or
        --------  -------                                                 
before December 31, 1997, this Plan will terminate having never become
effective.  This Plan shall be approved by the stockholders of the Company,
consistent with applicable laws, within twelve (12) months before or after the
date this Plan is adopted by the Board.

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

         21.  AMENDMENT OR TERMINATION OF PLAN.  The Board may at any time
              --------------------------------                            
terminate or amend this Plan in any respect, including without limitation
amendment of any form of Award Agreement or instrument to be executed pursuant
to this Plan.

         22.  NONEXCLUSIVITY OF THE PLAN.  Neither the adoption of this Plan by
              --------------------------                                       
the Board, the submission of this Plan to the stockholders of the Company for
approval, nor any provision of this Plan will be construed as creating any
limitations on the power of the Board to adopt such additional compensation
arrangements 

                                      -9-
<PAGE>
 
as it may deem desirable, including, without limitation, the granting of stock
options and bonuses otherwise than under this Plan, and such arrangements may be

                        TSI INTERNATIONAL SOFTWARE, LTD.

                        1997 DIRECTORS STOCK OPTION PLAN

                             As Adopted May 8, 1997



     1.  Purpose.  This 1997 Directors Stock Option Plan (this "Plan") is
established to provide equity incentives for nonemployee members of the Board of
Directors of TSI International Software, Ltd. (the "Company"), who are described
in Section 6.1 below, by granting such persons options to purchase shares of
stock of the Company.

     2.  Adoption and Stockholder Approval.  This Plan is effective on the date
(the "Effective Date") it is adopted by the Board of Directors of the Company
(the "Board").  This Plan shall be approved by the stockholders of the Company,
consistent with applicable laws, within twelve (12) months after the Effective
Date.

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

     4.  Number of Shares.  The maximum number of Shares that may be issued
pursuant to Options granted under this Plan (the "Maximum Number") is 150,000
Shares, subject to adjustment as provided in this Plan.  If any Option is
terminated for any reason without being exercised in whole or in part, the
Shares thereby released from such Option shall be available for purchase under
other Options subsequently granted under this Plan.  At all times during the
term of this Plan, the Company shall reserve and keep available such number of
Shares as shall be required to satisfy the requirements of outstanding Options
granted under this Plan; provided, however that if the aggregate number of
                         --------  -------                                
Shares subject to outstanding Options granted under this Plan plus the aggregate
number of Shares previously issued by the Company pursuant to the exercise of
Options granted under this Plan equals or exceeds the Maximum Number, then
notwithstanding anything herein to the contrary, no further Options may be
granted under this Plan until the Maximum Number is increased or the aggregate
number of Shares subject to outstanding Options granted under this Plan plus the
aggregate number of Shares previously issued by the Company pursuant to the
exercise of Options granted under this Plan is less than the Maximum Number.

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

provided that a public market for the Company's stock exists, through a "same

forth in the Grant, exercise of an Option shall always be subject to the

and all applicable state securities laws, as they are in effect on the date of
exercise.

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

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

    10.  Privileges of Stock Ownership.  No Optionee shall have any of the
rights of a stockholder with respect to any Shares subject to an Option until
the Option has been validly exercised.  No adjustment shall be made for
dividends or distributions or other rights for which the record date is prior to
the date of exercise, except as provided in this Plan.  The Company shall
provide to each Optionee a copy of the annual financial statements of the
Company at such time after the close of each fiscal year of the Company as they
are released by the Company to its stockholders.

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

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

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

event of (a) a dissolution or liquidation of the Company, (b) a merger or
consolidation in which the Company is not the surviving corporation (other than

replaced by the surviving corporation, which assumption, conversion or
replacement will be binding on all Optionees), (c) a merger in which the Company
is the surviving corporation but after which the stockholders of the Company

the Company in such merger, or which owns or controls another corporation which
merges, with the Company in such merger) cease to own their shares or other
equity interests in the Company, (d) the sale of all or substantially all of the
assets of the Company, or (e) the acquisition, sale or transfer of more than 50%
of the outstanding shares of the Company by tender offer or similar transaction,

options will become exercisable in full prior to the consummation of such event
at such times and on such conditions as the Committee determines, and if such
options are not exercised prior to the consummation of the corporate
transaction, they shall terminate in accordance with the provisions of this
Plan.

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

                        TSI INTERNATIONAL SOFTWARE, LTD.

                       1997 EMPLOYEE STOCK PURCHASE PLAN

                             As Adopted May 8, 1997


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

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

     3.  Administration.  This Plan shall be administered by the Board or by a
committee of not less than two members of the Board appointed to administer this
Plan (the "Committee").  As used in this Plan, references to the "Committee"
shall mean either such committee or the Board, if no committee has been
established.  Subject to the provisions of this Plan and the limitations of
Section 423 of the Code or any successor provision in the Code, all questions of
interpretation or application of this Plan shall be determined by the Board and
its decisions shall be final and binding upon all participants.  Members of the
Board shall receive no compensation for their services in connection with the
administration of this Plan, other than standard fees as established from time
to time by the Board for services rendered by Board members serving on Board
committees.  All expenses incurred in connection with the administration of this
Plan shall be paid by the Company.

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

         (a)  employees who are not employed by the Company or Participating
Subsidiaries ninety (90) days before the beginning of such Offering Period,
except that employees who are employed on the effective date of the registration
statement filed by the Company with the Securities and Exchange Commission
("SEC") under the Securities Act of 1933, as amended (the "Securities Act")
registering the initial public offering of the Company's Common Stock shall be
eligible to participate in the first Offering Period under the Plan;

         (b)  employees who are customarily employed for less than fifteen (15)
hours per week;

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

         (d)  individuals who provide services to the Company or any of its
Participating Subsidiaries as independent contractors whether or not
reclassified as common law employees, unless the Company or a Participating
Subsidiary 
<PAGE>
 
withholds or is required to withhold U.S. Federal employment taxes for such
individuals pursuant to Section 3402 of the Code.

     5.  Offering Dates.  The offering periods of this Plan (each, an
"Offering Period") shall be of twelve (12) months duration commencing on
February 1 and August 1 of each year and ending on the next January 31 and July
31 respectively, thereafter; provided, however, that notwithstanding the
                             -----------------                          
foregoing, the first such Offering Period shall commence on the first business
day on which price quotations for the Company's Common Stock are available on
the Nasdaq National Market (the "First Offering Date") and shall end on July 31,
1998.  Except for the first Offering Period, each Offering Period shall consist
of two (2) six-month purchase periods (individually, a "Purchase Period") during
which payroll deductions of the participants are accumulated under this Plan.
The first Offering Period shall consist of two Purchase Periods, any of which
may be greater or less than six months as determined by the Committee.  The
first business day of each Offering Period is referred to as the "Offering
Date".  The last business day of each Purchase Period is referred to as the
"Purchase Date".  The Board shall have the power to change the duration of
Offering Periods or Purchase Periods with respect to offerings without
stockholder approval if such change is announced at least fifteen (15) days
prior to the scheduled beginning of the first Offering Period or Purchase Period
to be affected.

     6.  Participation in this Plan.  Eligible employees may become participants
in an Offering Period under this Plan on the first Offering Date after
satisfying the eligibility requirements by delivering a subscription agreement
to the Company's treasury department (the "Treasury Department") not later than
fifteen (15) days before such Offering Date unless a later time for filing the
subscription agreement authorizing payroll deductions is set by the Board for
all eligible employees with respect to a given Offering Period.  An eligible
employee who does not deliver a subscription agreement to the Treasury
Department by such date after becoming eligible to participate in such Offering
Period shall not participate in that Offering Period or any subsequent Offering
Period unless such employee enrolls in this Plan by filing a subscription
agreement with the Treasury Department not later than fifteen (15) days
preceding a subsequent Offering Date.  Once an employee becomes a participant in
an Offering Period, such employee will automatically participate in the Offering
Period commencing immediately following the last day of the prior Offering
Period unless the employee withdraws or is deemed to withdraw from this Plan or
terminates further participation in the Offering Period as set forth in Section
11 below.  Such participant is not required to file any additional subscription
agreement in order to continue participation in this Plan.

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

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

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

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

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

                                      -2-
<PAGE>
 
              (a)  if such Common Stock is then quoted on the Nasdaq National
                   Market, its closing price on the Nasdaq National Market on
                   the date of determination as reported in The Wall Street
                   Journal;                                 ---------------
                   -------- 
              (b)  if such Common Stock is publicly traded and is then listed on
                   a national securities exchange, its closing price on the date
                   of determination on the principal national securities
                   exchange on which the Common Stock is listed or admitted to
                   trading as reported in The Wall Street Journal;
                                          ----------------------- 
              (c)  if such Common Stock is publicly traded but is not quoted on
                   the Nasdaq National Market nor listed or admitted to trading
                   on a national securities exchange, the average of the closing
                   bid and asked prices on the date of determination as reported
                   in The Wall Street Journal; or
                      ------------------------    

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

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

         (a)  The purchase price of the shares is accumulated by regular payroll
deductions made during each Offering Period.  The deductions are made as a
percentage of the participant's compensation in one percent (1%) increments not
less than two percent (2%), nor greater than fifteen percent (15%) or such lower
limit set by the Committee.  Compensation shall mean base salary, provided
however, that for purposes of determining a participant's base salary, any
election by such participant to reduce his or her regular cash remuneration
under Sections 125 or 401(k) of the Code shall be treated as if the participant
did not make such election.  Payroll deductions shall commence on the first
payday following the Offering Date and shall continue to the end of the Offering
Period unless sooner altered or terminated as provided in this Plan.

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

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

         (d)  On each Purchase Date, so long as this Plan remains in effect and
provided that the participant has not submitted a signed and completed
withdrawal form before that date which notifies the Company that the participant
wishes to withdraw from that Offering Period under this Plan and have all
payroll deductions accumulated in the account maintained on behalf of the
participant as of that date returned to the participant, the Company shall apply
the funds then in the participant's account to the purchase of whole shares of
Common Stock reserved under the option granted to such participant with respect
to the Offering Period to the extent that such option is exercisable on the
Purchase Date.  The purchase price per share shall be as specified in Section 8
of this Plan.  Any cash remaining in a participant's account after such purchase
of shares shall be refunded to such participant in cash, without interest;
provided, however that any amount remaining in such participant's account on a
Purchase Date which is less than the amount necessary to purchase a whole share
shall be carried forward, without interest, into the next Purchase Period or
Offering Period as the case may be.  In the event that this Plan has been
oversubscribed, all funds not used to purchase 

                                      -3-
<PAGE>
 
shares on the Purchase Date shall be returned to the participant, without
interest. No Common Stock shall be purchased on a Purchase Date on behalf of any
employee whose participation in this Plan has terminated prior to such Purchase
Date.

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

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

     10. Limitations on Shares to be Purchased.

         (a)  No participant shall be entitled to purchase stock under this Plan
at a rate which, when aggregated with his or her rights to purchase stock under
all other employee stock purchase plans of the Company or any Subsidiary,
exceeds $25,000 in fair market value, determined as of the Offering Date (or
such other limit as may be imposed by the Code) for each calendar year in which
the employee participates in this Plan.

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

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

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

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

     11. Withdrawal.

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

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

                                      -4-

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

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

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

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

     In the event of the proposed dissolution or liquidation of the Company, the
Offering Period will terminate immediately prior to the consummation of such
proposed action, unless otherwise provided by the Committee.  The Committee may,
in the exercise of its sole discretion in such instances, declare that the
options under this Plan shall terminate as of a date fixed by the Committee and
give each participant the right to exercise his or her option as to all of the
optioned stock, including shares which would not otherwise be exercisable.  In
the event of (i) a merger or consolidation in which the Company is not the
surviving corporation (other than a merger or consolidation with a wholly-owned
                       ----- ----                                              
subsidiary, a reincorporation of the Company in a different jurisdiction, or
other transaction in which there is no substantial change in the stockholders of
the Company or their relative stock holdings and the options under this Plan are
assumed, converted or replaced by the surviving corporation, which assumption,
conversion or replacement will be binding on all participants), (ii) a merger in
which the Company is the surviving corporation but after which the stockholders
of the Company immediately prior to such merger (other than any stockholder that
merges with the Company in such merger, or which owns or controls another
corporation that merges, with the Company in such merger) cease to own their
shares or other equity interest in the Company, (iii) the sale of all or
substantially all of the assets of the Company or (iv) the acquisition, sale, or
transfer of more than 50% of the outstanding shares of the Company by tender
offer or similar transaction, each option under this Plan may be assumed or an
equivalent option may be substituted by such surviving corporation or a parent
or subsidiary of such surviving corporation.  In the event such surviving
corporation does not assume or substitute the options under this Plan, (x) this
Plan will terminate upon the consummation of such transaction, unless otherwise
provided by the Committee and (y) the Committee may declare that the options
under this Plan shall terminate as of a date fixed by the Committee and give
each participant the right to exercise his or her option as to all of the
optioned stock.  If the Committee makes an option fully exercisable in the event

                                      -5-
<PAGE>
 
of a merger, consolidation or sale of assets, the Committee shall notify the
participant that the option shall be fully exercisable for a certain period, and
the option and this Plan will terminate upon the expiration of such period.

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

     15. Nonassignability.  Neither payroll deductions credited to a
participant's account nor any rights with regard to the exercise of an option or
to receive shares under this Plan may be assigned, transferred, pledged or
otherwise disposed of in any way (other than by will, the laws of descent and
distribution or as provided in Section 22 hereof) by the participant.  Any such
attempt at assignment, transfer, pledge or other disposition shall be void and
without effect.

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

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

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

     19. Equal Rights And Privileges.  All eligible employees shall have equal
rights and privileges with respect to this Plan so that this Plan qualifies as
an "employee stock purchase plan" within the meaning of Section 423 or any
successor provision of the Code and the related regulations.  Any provision of
this Plan which is inconsistent with Section 423 or any successor provision of
the Code shall, without further act or amendment by the Company or the Board, be
reformed to comply with the requirements of Section 423.  This Section 19 shall
take precedence over all other provisions in this Plan.

     20. Notices.  All notices or other communications by a participant to the
Company under or in connection with this Plan shall be deemed to have been duly
given when received in the form specified by the Company at the location, or by
the person, designated by the Company for the receipt thereof.

                                Option to Extend

          21.01  Provided that at the time of exercise of Tenant's right under
     this paragraph this Lease shall then be in full force and effect and Tenant
     shall not be in default of the Lease beyond any applicable notice and cure
     period, then Tenant shall have the right to extend the Term of the Lease in
     accordance with the further provisions of this Article (Tenant's "Right To
     Extend").  The Right To Extend may only be exercised by the Tenant giving

     as herein provided the CPI is no longer published or issued, the Landlord
     shall use such other index as is then generally recognized and accepted for
     similar determination of purchasing power.  Said fair market rent shall be
     determined as the fair market rent for a new lease; of the same type as
     this net Lease; with a term equal to the length of term for the Option
     Term; with a uniform rental rate over the length of the term; and for a
     premises comparable to the Leased Premises in a property comparable to the
     Project.  In the event 

                                      -3-
<PAGE>
 
     Landlord and Tenant cannot agree upon the fair market rent on or before the
     seventh month before the commencement of the Option Term, they shall submit
     to arbitration. The arbitration shall be a three member arbitration panel,
     one arbitrator selected by each of the parties and a third arbitrator
     selected by the first two arbitrators. Each arbitrator shall be a
     commercial real estate appraiser licensed in Connecticut. The manner of
     arbitration shall be that Landlord and Tenant shall each submit, in
     writing, one figure corresponding to such party's opinion of Basic Minimum
     Annual Rent for the Option Term (a "Last Best Offer"). The arbitrators
     shall then find the Basic Minimum Annual Rent for the Option Term to be
     only either the Last Best Offer given by Tenant. The majority vote of the
     arbitrators shall control. Landlord and Tenant shall share in the fees of
     the arbitrators equally. If the fair market rent has not been determined
     prior to the commencement of the Option Term, then the Basic Minimum Annual
     Rent previously in effect, on a per square foot of Tenant's Net Rentable
     Area, shall continue in effect until the fair market rent is determined, at
     which time there shall be a retroactive adjustment, and Tenant shall
     immediately owe the amount of any under paid Basic Minimum Annual Rent,
     together with interest from the shortfall in such underpaid Basic Minimum
     Annual Rent, at the rate of Wall Street Prime plus 2%. Tenant's exercise of
     Tenant's Right To Extend will only valid if it is in strict compliance with
     the provisions of this paragraph. Further, notwithstanding any other
     provisions for determining of the Basic Minimum Annual Rent, the Basic
     Minimum Annual Rent for the Option Term shall in no event be less than the
     Basic Minimum Annual Rent in effect immediately preceding the commencement
     of the Option Term."

     J.  New paragraph, Paragraph 25.09 is added to the Lease, as follows:

          "25.09  Tenant may use the lunch room located on the second floor of
     the building until Landlord finds a tenant to lease it.  When Landlord
     finds a tenant to lease it, Landlord will notify Tenant and the other
     tenants in the building.  If Tenant and some or all of the other tenants in
     the building want to continue to use it for a lunchroom, provided Tenant
     and some or all of the other tenants agree to add a proportionate share of
     the area of the lunchroom to their Leased Premises, and to increase their
     Basic Minimum Annual Rent and Tenant's Pro Rata Share accordingly, Landlord
     will continue to maintain the lunchroom as such otherwise, Landlord may
     proceed with a lease of the space currently used as a lunch room.  While

     the cleaning and maintenance of it."

     finish the Additional Second Floor Space in accordance with Tenant's finish
     plans, with a fit-out of up to a similar character as that provided to the
     original Leased Premises.  Such request must be in writing and must include
     the plans and specifications for the fit-out, subject to Landlord's
     approval, which shall not be unreasonably withheld or delayed.  Upon
     receipt of such request, Landlord shall promptly undertake and diligently
     pursue to completion the fit-out of the Additional Second Floor Space.
     Upon substantial completion of said space, and issuance of a certificate of
     occupancy therefore, the Additional Rent shall increase by a monthly amount
     which is necessary to amortize the cost of such fit-out over the balance of
     the Initial Term of this Lease in equal, consecutive monthly installments,
     with an interest rate of 10% per annum, the first payment commencing on the
     day of the month after substantial completion of the fit-out."

     F.  Exhibit A of the Lease is amended by adding an additional sheet,
showing the Additional Second Floor Space added by way of the First Lease
Amendment.  A copy of said sheet is attached hereto.

     The intent of this First Lease Amendment is to add 1,810 square feet of
tenant's net rentable area (the "Additional Second Floor Space") to the original
Leased Premises.  As of the Effective Date for the Additional Second Floor
Space, the Tenant's Net Rentable Area, the Basic Minimum Annual Rent and other
items dependent upon the square footage of the Leased Premises shall be adjusted
to reflect the addition of the Additional Second Floor Space, as set forth in
this First Lease Amendment.

     In the event of any conflict between this First Lease Amendment and the
Lease, this First Lease Amendment shall control, the Lease being, and is to
remain, in full force and effect in all other respects.

Landlord's building.  The outer vertical boundary of the Leases Premises is
outlined on the floor plan attached hereto as Exhibit A.  The upper boundary of
the Leased Premises shall be the lower surface of the suspended or finished

unfinished floor.  The vertical boundary of the Leased Premises shall be the
unfinished surface exposed to the Leased Premises of all walls bounding the
exterior of the building, other rentable area, building common area, and other
area not for use by Tenant (HVAC duct chases and structural column enclosures
for example).

     2.02  "The Project" means the real property appurtenant to the building in
which the Leased Premises is located.  The current real property boundary is
described in Exhibit B, attached hereto.

     2.03  "Tenant's Net Rentable Area" means the approximate area of the Leased
Premises plus a share of the core area of the buildings in the Project.

     2.04  "Tenant's Pro Rata Share" means the percentage obtained by dividing
Tenant's Net Rentable area by the total Net Rentable Area in the Project.
Although a specific Pro Rata Share may be set forth in the Data Section, the Pro
Rata Share shall be subject to adjustment upon increase or decrease of the total
Net Rentable Area in the Project.  The total Net Rentable Area in the Project as

Share upon execution of this Lease is 55.72%.

     2.05  "General Common Area" means all areas and facilities in the building

month of the Commencement Date.

     2.07  "Term of this Lease" means the Initial Term, and if the Lease grants
any option to extend the Term of this Lease, Term of this Lease shall include
any validly exercised option to extend.

     2.08  "Basic Operating Cost" shall mean all Operating Expenses of the
Project, which shall be computed on the accrual basis and shall consist of all
costs and expenses incurred by Landlord to maintain all facilities in the
operation of the Project and such additional facilities now and in subsequent
years as may be determined by Landlord to be necessary to the Project.  All
Operating Expenses shall be determined in accordance with generally accepted
accounting principles, which shall be consistently applied (with accruals
appropriate to Landlord's business, provided that accruals shall not include any
depreciation).  The term "Operating Expenses" shall include the amortized cost
of capital items, provided, however, that the useful life of any item shall in
no event exceed fifteen years, and provided that capital replacements shall not
be made unless the cost of repair shall be greater than the annual amount of the
amortized cost of the replacement.  The term "operating expenses" as used herein
shall mean all expenses and costs of every kind and nature which Landlord shall
pay or become obligated to pay because of or in connection with the ownership
and operation of the Project and supporting facilities of the Project.

employee's and Landlord's personal property used in connection therewith; (g)
the cost of repairs, replacement and general maintenance (excluding repairs and
general maintenance paid by proceeds of insurance or by Tenant or other third
parties, and alterations attributable solely to tenants of the Project other
than Tenant); (h) gardening, landscaping, planting (except for original
landscaping and planting), replanting and replacing of flowers and shrubbery;
(i) any and all General Common Area maintenance costs relating to public areas

special, ordinary and extraordinary, unforeseen as well as foreseen, of any kind
which are assessed, levied, charged, confirmed, or imposed by any public
authority upon the Project, its operation or the rent provided for in this Lease
Agreement (It is agreed that Tenant will be responsible for ad valorem taxes on
Tenant's personal property, if any, and on the value of leasehold improvements
to the extent that same exceed standard building allowances provided by Landlord
under this Lease); and (l) any other item reasonably expended for the
maintenance, operation, repair and insurance of the Project. Notwithstanding the

enforcement of any lease against any tenant; (iii) any environmental cleanup
costs for any condition existing at the Project as of the date of this Lease;
(iv) the cost of completion of the Project and any and all construction of any
tenant spaces, including the construction of Tenant's Leased Premises; and (iv)

defects or defects in the design of the Project. For the purposes of the
preceding sentence, "structural members" shall mean the building columns and
beams, the exterior concrete walls, the foundation, loan bearing walls, the

                                  ARTICLE III

                                 GRANT AND TERM

     3.01  In consideration of the rent and covenants herein reserved and
contained on the part of Tenant to be observed and performed, Landlord demises
and leases to Tenant and Tenant rents from Landlord the Leased Premises and the
improvements now or hereafter therein.  Together with the Leased Premises,
Landlord grants to Tenant and Tenant's employees and invitees the right to use
the General Common area, subject to the rules and regulations reasonably
established by Landlord.

     3.02  The Initial Term shall be the period of time set forth in the Data
Section.  The Term of this Lease shall commence on the Commencement Date.
Notwithstanding the exact number of years and/or months set forth for the
Initial Term in the Data Section, unless express provision is made to the
contrary, if the Commencement Date is not the first day of a calendar 

                                      -4-
<PAGE>
 
month, the Initial Term set forth in the Data Section shall be increased by any
partial month from the Commencement Date to the end of the calendar month.

                                   ARTICLE IV

                                      RENT

     4.01  Tenant agrees to pay Landlord during the Term of this Lease the Basic
Minimum Annual Rent, it being understood that the Basic Minimum Annual Rent is
$0 until December 1, 1990.

     4.02  Tenant agrees to pay Landlord during the Term of this Lease
Additional Rent, consisting of:  (i) Tenant's Pro Rata Share of the Basic
Operating Cost; (ii) all utility charges which are not included as items of
Basic Operating Cost but are the cost responsibility of Tenant under other
provisions of this Lease (which have not been paid by Tenant directly to the
utility providing the service under other provisions of this Lease); (iii) and
any other item specifically set forth elsewhere in this Lease as an item of
Additional Rent or as an item which is in any other manner the cost
responsibility of Tenant.  Landlord shall give Tenant within a reasonable time
after the commencement of Landlord's fiscal operating year for the Project a
statement of Tenant's Pro Rata Share of estimated Basic Operating Cost for the
ensuing year.  Tenant agrees to pay Tenant's Pro Rata Share of the Basic
Operating Cost for each fiscal year in monthly installments in accordance with
Landlord's statement.  Landlord shall, within ninety days after the end of each
fiscal year for which Basic Operating Cost has been charged in accordance with
the estimated charges, give to Tenant a statement of the actual Basic Operating
Cost incurred for the previous year.  Adjustment shall be made for any
overpayment or underpayment of the actual charges resulting from any variance
between the actual Basic Operating Cost for the previous year and the estimated
Basic Operating Cost paid by Tenant, which adjustment may be made by increasing
or decreasing the Additional Rent charges for the next year, a refund or a lump
sum charge, provided, however, that Landlord shall not be required to make such
adjustment more than once per year.  If during any fiscal operating year,
Landlord shall not have delivered to Tenant the statement mentioned for such
year, Tenant shall continue to pay Landlord the sums payable for the immediately
preceding year, until the statement for the current year shall have been
delivered, at which time the monthly payments by Tenant shall be adjusted
retroactively.  Upon the request of Tenant, Landlord shall supply reasonable
itemization and documentary back-up for the statement of the actual Basic
Operating Cost.  If during all or part of any fiscal year any particular item or
items of service or work (which would constitute an element of Additional Rent
hereunder) are not furnished to any portion of the Project due to the fact that
such portion is not completed, occupied or leased, then for the  purposes of
computing Additional Rent payable hereunder, the amount of such expenses for
such items shall be increased by an amount equal to the expenses which would
have reasonably been incurred during such period if Landlord had at his own
expense furnished such items of service or work to such portion of the Project,
provided in no event shall Landlord recoup more than 100% of the expenses
actually incurred by Landlord.  Utility charges set forth as a portion of
Additional Rent, above, may be included with the statement of estimated Basic
Operating Cost and billed and adjusted in the same manner as Tenant's Pro Rata
Share of the Basic Operating Cost.  If any part of the first or last Lease Years
of the Term of this Lease shall include part of a tax or operating expense year,
Tenant's liability 

                                      -5-
<PAGE>
 
under this paragraph shall be apportioned so that Tenant shall pay only for such
parts of such tax year and operating expense years that shall be included in the
Term of this Lease. Landlord may elect to bill the full amount of any item of
Additional Rent which is not an item of Basic Operating Cost as such item of
expense is incurred by Landlord (repair of damage caused by Tenant, for
example). All items of Additional Rent which are capital items not specifically
the immediate cost responsibility of Tenant pursuant to other terms of the Lease
shall be amortized in accordance with generally accepted accounting principles,
provided that no item shall have a useful life of more than fifteen years.
Notwithstanding the foregoing, items (i) and (ii) of additional rent shall be
payable for the period beginning with the Leased Premises Completion Date
(defined in Article XIX) and shall not begin to accrue until such date.

     4.03  The Basic Minimum Annual Rent and the monthly installment portion of
the Additional Rent shall be due in installments, commencing with the
Commencement Date and continuing on the first day of each month thereafter, in
advance.  If the Commencement Date is not the first day of a calendar month, the
installment due on the Commencement Date shall be pro rated for the fractional
period remaining in the month of the Commencement Date.  It is the intention of
the Landlord and Tenant that the rents herein specified shall be net to the
Landlord in each year during the Term of this Lease, payable without any
reduction, abatement or setoff, and that all costs, expenses and obligations of
every kind relating to the Leased Premises, whether or not specifically set
forth in this Lease, which may arise or become due under any contingency
whatsoever during the Term of this Lease shall be paid by the Tenant and the
Tenant shall indemnify the Landlord and save the Landlord harmless from and
against all such costs, expenses and obligations.  All installments of rent past
due beyond thirty days shall bear interest at the lesser of two percentage
points per annum over the prime rate of interest as announced by The Connecticut
Bank and Trust Company, N.A., or its successor, or the maximum rate permitted by
applicable law, from date due until payment is received.  Any liability for
unpaid Basic Minimum Annual Rent and Additional Rent shall survive the
termination of the Lease.

                                   ARTICLE V

                               CONDUCT OF TENANT

     5.01  Tenant agrees that Tenant and Tenant's permitted assignees or sub-
lessees shall use the Leased Premises for the sole and exclusive purpose set
forth in the Data Section.  The use of the Leased Premises shall also be in
accordance with the ordinances and regulations of the municipality in which the
Leased Premises is located.  Unless the use set forth in the Data Section
expressly provides otherwise, the use of the Leased Premises shall be limited to
the operation of a general business office.  Without limitation of the
foregoing, Tenant agrees that the Leased Premises will not be used for any
purpose other than that provided above.  Tenant agrees to comply with all rules
and regulations, of which Tenant is given notice, reasonably established by
Landlord for the governing of conduct of tenants in general in the Project.  The
current rules and regulations for tenants in the Project are set forth in
Exhibit C.

     5.02  Tenant agrees that Tenant will not keep, use, sell or offer for sale
in or upon the Leased Premises any article which may be prohibited by the
standard form of fire insurance policy.  Tenant agrees to pay any increase in
premiums for fire and extended and/or all risk 

                                      -6-
<PAGE>
 
coverage insurance that may be charged during the Term of this Lease on the
amount of such insurance which may be carried by Landlord on the Project,
resulting from the type of equipment, merchandise or services used by Tenant in
the Leased Premises, whether or not Landlord has consented to the same. In
determining whether increased premiums are the result of Tenant's use of the
Leased Premises, a schedule issued by the organization making the insurance rate
on the Leased Premises, showing the various components of such rate, shall be
conclusive evidence of the several items and charges which make up the fire
insurance rate on the Leased Premises and the Project.

     5.03  Tenant shall not commit or suffer to be committed any waste upon the
Leased Premises or Project or any nuisance or other act or thing which may
disturb the quiet enjoyment of any other tenant in the Project.

     5.04  Tenant shall, at Tenant's sole cost and expense, comply with all of
the requirements of all county, municipal, state, federal and other applicable
governmental authorities, now in force or which may hereafter be in force and
not being reasonably disputed by Tenant, pertaining to the Tenant's use of the
Leased Premises.  Tenant shall faithfully observe in the use of the Leased
Premises all federal, state, county and municipal laws, ordinances and
regulations now in force or which may hereafter be in force not being reasonably
disputed by Tenant, excepting any structural changes required by such
authorities which are not caused by the act or neglect of the Tenant or by
Tenant's specific use of the Leased Premises.  Specific references is made to
Tenant's duty to comply with all state, federal and local laws concerning
environmental protection and Tenant's conduct at the Project.  Tenant shall not
undertake any activity which would cause the Leased Premises to be classified as
an "Establishment" under the Connecticut General Statutes.  Tenant agrees to
indemnify Landlord against any cost and expense which Landlord may suffer by
reason of Tenant's failure to comply with the laws governing its conduct at the
Project, including all laws concerning environmental protection.  Landlord
warrants that the Project and the Leased Premises shall comply with all
applicable laws affecting their construction, as of the date of Tenant's
occupancy, specific reference being made to building codes and environmental
laws.  Landlord further represents that the use of the Leased Premises as a
general office is permitted under the zoning regulations of the Town of Wilton,
and the Leased Premises shall comply with all applicable laws affecting its use
as a general office as of the date of occupancy.

     5.05  Tenant will not place or maintain, or cause to be placed or
maintained, on any portion of the Project exterior to the Leased Premises or any
portion of the Project (including the Leased Premises) visible from the exterior
of the Leased Premises, any sign or advertising matter without Landlord's
written consent.  Tenant shall not place any object on any portion of the
Project exterior to the Leased Premises without Landlord's written consent.
Landlord shall provide the Project with two monuments at the front of the
Project, adjacent Danbury Road, one monument to be for signage to the effect of
"TSI International Building" and the other monument to be for the address of the
building and to contain the signage for other tenants of the building, the two
monuments to be of equal size.  Landlord shall not unreasonably withhold
Landlord's consent to Tenant's design of the "TSI International Building"
signage, but the same shall also be subject any required approval under the
Wilton Zoning Regulations.  Tenant shall not install or maintain any window
treatment without the prior written consent of Landlord.

                                      -7-
<PAGE>
 
     5.06  Tenant agrees to keep the Leased Premises in a clean and sanitary
condition and free from trash, inflammable material and other objectionable
matter and to make all interior repairs other than to Landlord's electrical,
plumbing and mechanical systems.  Tenant shall maintain all equipment installed
by Tenant at Tenant's own cost and expense.  Tenant shall not make any building
alteration or addition to the Leased Premises without Landlord's consent, which
shall not be unreasonably withheld.

     5.07  If Tenant refuses or neglects to perform any item of maintenance or
repair which is Tenant's responsibility within a reasonable time, Landlord may
make such repairs without liability to Tenant for any loss or damage that may
accrue to Tenant's merchandise, fixtures, or other property or to Tenant's
business by reason thereof, and upon completion thereof, Tenant shall pay
Landlord's cost for making such repairs upon presentation of an invoice
therefor, as Additional Rent, which shall include interest from the time payment
of such sums by Tenant is thirty days past due, at the same rate as that due for
overdue rental payments.  In the case of a repair which is not an emergency
repair, Landlord shall not exercise Landlord's right to make the repair unless
Tenant has not commenced the repair within ten days after written demand from
Landlord and proceeds to complete same with diligence.

     5.08  Tenant shall promptly pay all contractors and materialmen hired by
Tenant to furnish any labor or materials which may give rise to the filing of a
mechanic's lien against the Project attributable to contracts entered into by
the Tenant.  Should any such lien be made or filed, Tenant shall cause same to
be discharged as a lien against the Project within the sooner of (i) forty-five
days after Tenant receives notice of such lien or (ii) forty-five days after
request by Landlord to remove such lien.  If bond is filed and such lien is
discharged, Tenant shall not be obligated to discharge the lien by payment.
Notwithstanding any notice and grace period before default elsewhere set forth
in this Lease, if Tenant shall fail to discharge such lien within the time
period set forth in this paragraph above, and shall further fail to discharge
such lien within ten more business days after notice of failure to discharge the
lien is given from Landlord, then Tenant shall be in material default of the
Lease, without any further notice or grace period.

Premises with heating, ventilation and air conditioning Monday through Friday
from 7:00 a.m. to 9:00 p.m. and Saturday from 8:00 a.m. to 2:00 p.m.  Further

or buildings in the 

                                      -8-

Project, all General Common Area in the Project, and all mechanical equipment
installed by Landlord for heating, ventilation and air conditioning, plumbing
and other mechanical systems of the Leased Premises. Tenant shall pay: (i)
Tenant's Pro Rata Share for maintenance and repair of the portion of said
mechanical systems which are building standard; and (ii) the full cost of said
maintenance and repair for the portion of said mechanical systems servicing the
Leased Premises in excess of building standard. Although Landlord is responsible
for the performance of certain work under this paragraph, the cost of such work
may be Tenant's responsibility under this and other provisions of the Lease, in
full or as a Pro Rata Share.

     6.02  Landlord shall furnish keys to Tenant so that Tenant may have access
to the Leased Premises before and after normal business hours.  No locks other
than those furnished by Landlord shall be installed on the doors providing
access to the Leased Premises without Landlord's written consent.  Tenant shall
furnish to Landlord keys to any such locks allowing access to Tenant's Leased
Premises.

     6.03  Landlord shall have the right to make alterations and/or additions to
the Project and the buildings in the Project.  Landlord shall have the right to
construct or demolish other buildings and structures in the Project and may
alter the grade and/or location of the improvements in the Project.  The
exercise by Landlord of any right under this paragraph shall be limited so that
there shall be no unreasonable interference with Tenant's use of the Leased
Premises, the General Common Area or Tenant's use of the parking area.

     6.04  Landlord shall have the right to establish rules and regulations for
the use of the parking areas by Tenant and other tenants in the project, but
Landlord shall not have any duty to police the traffic in the parking areas.
Tenant shall have the use of the parking areas, existing from time to time in
the Project, for the benefit of Tenant's employees, visitors and customers, in
common with other tenants in the Project, which use is to be in accordance with
Tenant's Pro Rata Share of the parking areas available for all tenants in the
Project.  The ratio of parking spaces to the tenant's net rentable area for the
entire building is 3.94 spaces per thousand square feet of tenant's net rentable
area, and Tenant shall have its 3.94 spaces per square foot of its Net Rentable
Area available for its use at all times.

                                  ARTICLE VII

                  INSURANCE, INDEMNITY AND SUBROGATION WAIVER

     7.01  Tenant shall, from the Leased Premises Completion Date, keep in full
force and effect a policy of public liability and property damages insurance.
Tenant's insurance policy shall insure against Tenant's liability for all acts
and omissions with respect to conduct in the Leased Premises and the Project of
Tenant and Tenant's agents, servants, employees, licensees and invitees.  The
policy limits of Tenant's insurance shall be at least $1,000,000 per occurrence,
or such other limits as to public liability and property damage as Landlord may
reasonably require.  Tenant's policy shall name Landlord as an additional
insured and shall contain a clause providing that the insurer will not cancel or
change the insurance without first giving the Landlord fifteen days prior
written notice.  Tenant's insurance policy shall be with an insurance company
selected by Tenant and approved by Landlord; Landlord's approval not to be
unreasonably withheld and 

                                      -9-
<PAGE>
 
to be based upon a sufficient rating by a service such as A. M. Best. A copy of
the policy or a certificate of insurance shall be delivered to Landlord prior to
the Leased Premises Completion Date.

     7.02  Tenant shall, from the Leased Premises Completion Date, keep in full
force and effect a hazard and all risk insurance policy, including fire,
extended and all risk type coverage, in an amount adequate to cover the cost of
repair and replacement of all alterations, decorations, or improvements made by
Tenant in the Leased Premises.  Tenant's policy shall name Landlord as an
additional insured and shall contain a clause that the insurer will not cancel
or change the insurance without first giving the Landlord fifteen days prior
written notice.  Tenant's insurance policy shall be with an insurance company
selected by Tenant and approved by Landlord, Landlord's approval not to be
unreasonably withheld and to be based upon a sufficient rating by a service such

buildings, structures or improvements (excluding tenant improvements required to
be insured by Tenant under other terms of this Lease) in the Project, in an
amount adequate to cover the cost of replacing the foregoing in the event of
fire or other destruction.  In the event of fire or other destruction to such
property, Landlord agrees, subject to the rights of any bona fide mortgagee to
insurance proceeds, to immediately collect or cause to be collected the
insurance proceeds and to apply the same to the reconstruction and repair of the
damaged property.  Tenant shall pay Tenant's Pro Rata Share of the premiums for
the insurance specified herein as an item of Basic Operating Cost Additional
Rent.

     7.04  Each policy of public liability insurance, hazard insurance or other
insurance insuring risks arising out of any occurrence at the Project, carried
by Tenant or Landlord, shall provide that the insurer waives any rights of
subrogation against the Landlord (in the case of Tenant's policies) and against
the Tenant (in the case of Landlord's policies) in connection with or arising
out of any claim or benefit provided under such insurance policy.  In no event
shall Tenant or any person or corporation claiming an interest in the Leased
Premises by, through or under Tenant and over whom Tenant shall have control,
claim, maintain or prosecute any action or suit at law or in equity against the
Landlord for any loss, cost or damage caused by or resulting from fire or other
risk or casualty in the Project for which Tenant is or may be insured under a
standard hazard and all risk insurance policy, including fire, extended and/or
all risk type coverage, whether or not the property (tangible or intangible) is
insured or required to be insured under this Lease, and whether or not caused by
the negligence of the Landlord, or the agents, or servants, or employees of the
Landlord.  In no event shall Landlord or any person or corporation claiming an
interest in the Project by, through or under Landlord and over whom Landlord
shall have control, claim, maintain or prosecute any action or suit at law or in
equity against the Tenant for any property damage to the Project caused by or
resulting from fire or other risk or casualty in the Project for which Landlord
is required to be insured under the provisions of the Lease, whether or not
caused by the negligence of the Tenant or the agents, servants and/or employees
of the Tenant.

     7.05  Tenant will indemnify Landlord and save Landlord harmless from and
against any and all third party claims, actions, damages, liability and expense
in connection with loss of life, personal injury and/or damages to property
arising from or out of any occurrence in, upon or at the Project occasioned
wholly or in part by any act or omission of Tenant, or Tenant's agents,
servants, employees, licensees or invitees.  In case Landlord shall be made a
party to any litigation commenced by or against Tenant in any action described
in this paragraph, the Tenant shall protect Landlord and hold Landlord harmless
and shall pay all costs, expenses and reasonable attorney's fees incurred or
paid by Landlord in connection with such litigation.

     7.06  Landlord will indemnify Tenant and save Tenant harmless from and
against any and all third party claims, actions, damages, liability and expense
in connection with loss of life, personal injury and/or damages to property
arising from or out of any occurrence in, upon or at the Project occasioned
wholly or in part by any act or omission or Landlord, or Landlord's agents,
servants, employees, licensees or invitees, and not in any part by Tenant or
Tenant's agents, servants, employees, licensees or invitees.  In case Tenant
shall be made a party to any litigation commenced by or against Landlord in any
action described in this paragraph, the Landlord shall protect Tenant and hold
Tenant harmless and shall pay all costs, expenses and reasonable attorney's fees
incurred or paid by Tenant in connection with such litigation.

     7.06  Landlord will indemnify Tenant and save Tenant harmless from and
against any and all third party claims, actions, damages, liability and expense
in connection with loss of life, personal injury and/or damages to property
arising from or out of any occurrence in, upon or at the Project occasioned
wholly or in part by any act or omission of Landlord, or Landlord's agents,
servants, employees, licensees or invitees, and not in any part of Tenant or
Tenant's agents, servants, employees, licensees or invitees.  In case Tenant

                                  ARTICLE VIII

                                   UTILITIES

     8.01  From and after the Commencement Date, Tenant shall pay all charges
for utilities used, consumed in or allocable to the Leased Premises, including,
but not limited to, fuel, electricity, water and gas.  Said utilities may be
either directly metered to Tenant or shared with other tenants.  If any utility
consumption in the Leased Premises is not separately metered, Landlord may
allocate the shares utility consumption to the Leased Premises in any reasonable
manner, except that the Tenant electric shall be allocated and charged as
provide below.  In the case of building systems such as HVAC, utility
consumption of such systems may be allocated in accordance with Tenant's Pro
Rata Share.  The charges for all utilities not paid directly to the utility
providing the service shall be paid to Landlord as an element of Additional
Rent; and Tenant shall, at Landlord's option, either pay the separately metered
utilities directly to the utility providing the service, or pay for said
separately metered utilities as an item of Additional Rent.  Tenant and Landlord
acknowledge that the electricity consumed in the Leased Premises is not
separately metered, and Tenant and Landlord agree that the electricity consumed
in the Leased 

                                     -11-
<PAGE>
 
Premises by Tenant shall be fixed at $1.25 per square foot of Tenant's Net
Rentable Area for the first year from the Leased Premises Completion Date and
shall be $1.25 per square foot plus any rate increase by the utility providing
the electricity from the Leased Premises Completion Date. The electricity
charges shall be billed in monthly installments as set forth in Articles IV. The
$1.25 per square foot rate set forth above is based on normal office usage, and
Landlord reserves the right to increase the Tenant electric charges in the event
that Tenant's electric consumption shall be in excess of normal office usage
(for example, excess usage due to a large computer installation with high energy
consumption). Landlord acknowledges that Landlord has inspected Tenant's
existing premises at 295 Westport Avenue, Norwalk, Connecticut. Landlord further
acknowledges that if the usage in the new Leased Premises is the same as that in
the 295 Westport Avenue Premises, on a per square foot basis, such usage would
be normal office space usage and as such would not be subject to increase due to
excess usage.

                                   ARTICLE IX

                              ESTOPPEL STATEMENT,

                            ATTORNEY, SUBORDINATION

     9.01  Upon request of Landlord or any mortgages of Landlord, Tenant shall
execute an estoppel certificate, certifying the status of any facts with respect
to the Lease.  Estoppel certification may include:  whether the Lease is in full
force and effect; the rentals due under the Lease and the degree to which same
have been paid; that there are no defenses or claims against Landlord for any
alleged violation of the Lease by Landlord, or a statement of such defenses or
claims; acknowledgment of the interpretation or meaning of any term of the
Lease, provided such acknowledgment shall not change any term or provision
hereof; any such other matters reasonably requested to be certified in the
estoppel certificate.

     9.02  The Tenant agrees that the Lease and all rights of the Tenant herein
shall, at the election of Landlord or mortgagee, be subordinate to the lien of
any bona fide mortgage or mortgages now or with may hereafter be placed on the
Project or any part of the Project during the term of this Lease, provided such
mortgages provides a standard right of non-disturbance to Tenant.  In the event
any proceeding is brought for the foreclosure of the Leased Premises, Tenant
agrees to attorn to the mortgages in the event of strict foreclosure, or to the
purchaser in the event of foreclosure by sale or deed in lieu of foreclosure,
and recognize such mortgages or purchaser (as the case may be) as the Landlord
under this Lease, provided such mortgages or purchaser recognizes Tenant's right
of non-disturbance.  Tenant further agrees to execute any further instrument or
instruments which the Landlord or its successors in title may reasonably at any
time require to evidence the subordination of this Lease to the lien of any such
mortgage or mortgages and Tenant's agreement to attorn, provided, however, that
the Landlord obtains a standard non-disturbance agreement from the mortgages for
the benefit of the Tenant.  Notwithstanding the foregoing, if there shall be a
bona fide first mortgage placed on all or a portion of the Project, this Lease
shall not be subordinated to any other encumbrance subsequent in right to the
first mortgage unless the first mortgagee shall consent to such subordination,
in writing.

                                     -12-
<PAGE>
 
     9.03  Tenant agreed to execute and deliver to Landlord or the party
designated by Landlord, within ten days after presentation of the proposed form,
any estoppel certificate and/or subordination, attornment and/or non disturbance
agreement requested to be executed by Tenant pursuant  to the terms of this
Lease.  Tenant further agrees to include in any such documents if requested by
Landlord:  an agreement not to pay Landlord rent for more than one month in
advance; an agreement to give any bona fide mortgagee a notice of any alleged
default by Landlord and a reasonable time for such mortgagee to have such
default cured before Tenant will exercise any right to terminate this Lease; and
an agreement that Tenant will not look to such mortgages for the return of any
security deposit or other monies not actually received by such mortgages.  If
Tenant shall not have delivered the executed documents, required to be executed
and delivered under this Article, within the ten day period set forth above,
Landlord may give Tenant written notice of Tenant's failure to deliver such
documents, and if Tenant shall then fail to deliver said executed documents
within three business days after delivery of such written notice,
notwithstanding any provision for notice and grace period for default elsewhere
contained in this Lease, Tenant shall be in material default of the Lease, and
Landlord shall have all rights provided for in the event of such default,
including termination; and Tenant shall be liable for all resulting
consequential damages to Landlord.

                                   ARTICLE X

                         DESTRUCTION OF LEASED PREMISES

     10.01  Landlord agrees, subject to and excepting the other provisions of
this Article, that if the Leased Premises shall be damaged by fire or other
casualty during the terms of this lease, Landlord shall, at Landlord's own
expense, use best efforts to cause the damage to be promptly repaired within a
reasonable time after such damage has occurred, which period shall not exceed
six months.  If by reason of such occurrence, any portion of the Leased Premises
is thereby rendered untenantable and Tenant cease use of said portion, the rent
and other charges payable by Tenant hereunder shall be abated in proportion to
the area of the Leased Premises which is rendered untenantable and which is not
used by Tenant, said abatement to continue until the sooner of the time when the
Leased Premises is repaired or until Tenant uses the damages portion of the
Leased Premises.  Landlord's obligation to restore under this Article shall be
limited to the extent of insurance proceeds made available by any mortgagee
having control over the disposition of such proceeds.  If Landlord shall fail to
commence repair within two months of the casualty and diligently pursue same to
completion, all as a result of the mortgage failing to make available casualty
insurance proceeds for such repair, either party may terminate this Lease upon
written notice to the other.

     10.02  In the event that forty percent or more of the Leased Premises shall
be damaged or destroyed by fire or other cause during the Term of this Lease,
Landlord or Tenant shall have the right, to be exercised by written notice to
the other party, within sixty days from and after said occurrence, to elect to
cancel and terminate this Lease.  Upon the giving of such notice, the term of
this Lease shall expire by lapse of time upon the ninetieth day after such
notice is given, and Tenant shall vacate the Leased Premises and surrender the
same to Landlord on such date of expiration.

                                   ARTICLE XI

                    EMINENT DOMAIN AND CESSATION OF BUSINESS

     11.01  In the event any portion of the Leased Premises or any portion of
the Project which renders the Leased Premises unusable is taken in condemnation
proceedings or by any right of eminent domain or for any public or quasi-public
use, this Lease shall terminate as of the date of vesting of title in the
condemning authority and all rent, including additional rent, payable under this
lease shall be paid to that date.

     11.02  In the event of any taking provided for in this Article, all
proceeds of any award, judgment or settlement payable by the condemning
authority shall be and remain the sole and exclusive property of Landlord, and
Tenant waives any right to make any claim to said award, judgment or settlement
received by Landlord.  Tenant may pursue its own claim against the condemning
authority permitted by statute to be paid to Tenant without diminishing or
reducing the award, judgment or settlement payable to Landlord.

                                  ARTICLE XII

                           ASSIGNMENT AND SUBLETTING

     12.01  Tenant will not assign this Lease in whole or in part nor sublet all
or any part of the Leased Premises without the prior written consent of
Landlord, which shall not be unreasonably withheld.  Landlord hereby expressly
consents to any assignment or subletting to a related entity which controls
Tenant, which Tenant controls, which is a substantial stockholder or partner in
Tenant or in which Tenant is a substantial stockholder or partner.  The consent
by Landlord to any assignment of subletting shall not constitute a waiver of the
necessity for such consent to any subsequent assignment or subletting.  This
prohibition against assigning or subletting shall be construed to include a
prohibition against any assignment or subletting by operation of law.  If the
Leased Premises shall be occupied by anybody other than Tenant, Landlord may
collect rent from the assignee, under-tenant or occupant and apply the net
amount collected to the rent herein reserved, but no such assignment,
underletting, occupancy or collection shall be deemed a waiver of this covenant,
or the acceptance of the assignee, under-tenant or occupant as tenant, or a
release of Tenant from the further performance by Tenant of covenants on the
part of Tenant herein contained.  Notwithstanding any assignment or sublease,
Tenant shall remain primarily liable on this Lease and shall not be released
from performing any of the terms, covenants and conditions of this Lease, but
Tenant and such assignee, under-tenant or occupant shall thereafter be jointly
and severally liable for the full and faithful performance of the obligations of
Tenant under this Lease.  Any attempted assignment by Tenant without the prior
written consent of Landlord shall be void.  No assignment or subletting shall
provide for a rental payment, or other payment for use and occupancy or
utilization, based in whole or in part on the net income or profits derived by
any person or entity from the property assigned, subleased, occupied or utilized
(other than an amount based upon a fixed percentage of sales), and any such
purported assignment or subletting base upon such payment shall be void and any
amount payable thereunder or any rental amount therefor passed to any person or
entity shall not have deducted therefrom any expenses or costs related in any
way to the leasing of such space.

                                     -14-
<PAGE>
 
     12.02  In the event Tenant desires to sublet or assign this Lease in whole
or in part to a non related entity and the resulting agreement provides the
Tenant with any net profit, Landlord and Tenant shall share in such profit on
the basis of 50% to Landlord and 50% to Tenant.  Net profit shall be the gross
difference between the rent payable by the subtenant or assignee and the rent
payable by Tenant hereunder (on a per square foot basis in the case of a partial
space), net of any reasonable rent concessions given to the subtenant or
assignee as an inducement to enter into the sublease or assignment, any
reasonable real estate brokerage commission and reasonable renovation expense
Tenant incurs in the course of the subletting or assigning to the subtenant or
assignee.  If the rent payable to the subtenant or assignee is not greater than
the rent payable by Tenant hereunder, there shall be no net profit.

                                  ARTICLE XIII

                             DEFAULT OF THE TENANT

     13.01  In the event of any failure of Tenant to pay any Basic Minimum
Annual Rent, Additional Rent or any other monies payable to Landlord under this
Lease within ten (10) days after written notice of failure to pay said sums,
Tenant shall be in material default of the Lease.  Tenant shall also be in
material default of this Lease upon the happening of any of the following:  (i)
the failure to deliver any estoppel or subordination, non disturbance and/or
attornment agreement within the time limits set forth for default in the Article
of this Lease requiring execution and delivery of such documents; (ii) the
failure to have any mechanic's lien discharged within the time period set forth
for default in the Article requiring removal of mechanic's liens; (iii) the
failure to commence within thirty (30) days after written notice of failure to
perform, and diligently pursue the performance of, any other of the terms,
conditions or covenants of this Lease to be observed or performed by Tenant;
(iv) if Tenant or any guarantor shall become bankrupt or insolvent, or file any
debtor proceedings, or take or have taken against them, in any court, pursuant
to any statute either of the United States or of any State, a petition in
bankruptcy or insolvency or for the reorganization or for the appointment of a
receiver or trustee of all or a portion of Tenant's property or make an
assignment for the benefit of creditors; or (v) if Tenant's interest in this
Lease shall be taken under any writ of execution.  The foregoing conditions of
default shall be limited to the extent required by any state or federal laws
affecting this Lease and Landlord's rights against Tenant, including the United
States bankruptcy laws.  To the extent permitted by law, all payments are due on
the due dates set forth in the Lease, and there shall be no grace period for the
due date of the rent other than the above ten day period after notice from
Landlord.

     13.02  In the event of default, then Landlord, besides other rights or
remedies Landlord may have, shall have the right to terminate this Lease and
proceed under any law entitling Landlord to recover possession of the Leased
Premises, and to the extent permitted by law, shall be entitled the right of
immediate reentry and to eject Tenant from the Project, without resort to court
proceedings.  Upon such default, to the extent permitted by law, Tenant's
property may be removed and stored in a public warehouse or elsewhere at the
cost of, and for the account of Tenant.  Tenant acknowledges that this Lease is
a commercial Lease, and to the extent permitted by law, Tenant waives the
requirement of a statutory notice to quit possession prior to commencement of
summary process proceedings.

                                     -15-
<PAGE>
 
     13.03  Should Landlord elect to reenter, as herein provided, or should it
take possession pursuant to legal proceedings or pursuant to any notice provided
for by law, Landlord may either terminate this Lease or Landlord may from time
to time, without terminating this Lease, make such alterations and repairs as
may be necessary in order to relet the Leased Premises, or any part thereof, for
such term or terms (which may be for a term extending beyond the terms of this
Lease) and at such rental or rentals and upon such other terms and conditions as
Landlord in Landlord's discretion may deem advisable.  Upon each such reletting,
all rentals received by the Landlord from such reletting shall be applied first
to the payment of any indebtedness other than rent due hereunder from Tenant to
Landlord; second, to the payment of any costs and expenses of such reletting,
including brokerage fees and attorney's fees and of costs of such alterations
and repairs; third, to the payment of rent due and unpaid hereunder, and the
residue, if any, shall be held by Landlord and applied in payment of future rent
as the same may become due and payable hereunder.  If such rentals received from
such reletting during any month are less than that to be paid during that month
by Tenant hereunder, Tenant shall pay any deficiency to Landlord.  Such
deficiency shall be calculated and paid monthly.  No such reentry or taking
possession of the Leased Premises by Landlord shall be construed as an election
on Landlord's part to terminate this Lease unless a written notice of such
intention be given to Tenant or unless the termination thereof be decreed by a
court of competent jurisdiction.  Notwithstanding any such reletting without
termination, Landlord may at any time thereafter elect to terminate this Lease
for such previous breach.  Should Landlord at any time terminate this Lease for
any breach, in addition to any other remedies Landlord may have, Landlord may
recover from Tenant all damages Landlord may incur by reason of such breach,
including the cost of recovering the Leased Premises, reasonable attorney's
fees, and the present value of the lost rent resulting from the failure of
Landlord or Tenant to obtain another Tenant for the Leased Premises for any
period of time after Tenant's default, and/or resulting from the fact that the
reasonable rental value of the Lease Premises at the time of Tenant's default is
less than the value of the remaining rental payments due under this Lease.
Landlord acknowledges a duty to mitigate damages under the law.

     13.04  In case Landlord shall retain an attorney to enforce the provisions
of this Lease or if suit shall be brought for recovery of possession of the
Leased Premises, for the recovery of rent or any other amount due under the
provisions of this Lease, or because of the breach of any other covenant herein
contained on the part of Tenant to be kept or performed, Tenant shall pay to
Landlord all reasonable expenses incurred therefor, including a reasonable
attorney's fee.

                                  ARTICLE XIV

                                SECURITY DEPOSIT

     14.01  Tenant's Security Deposit shall be due and payable to Landlord upon
execution of this Lease, and may be in the form of an unconditional and
irrevocable letter of credit in favor of Landlord or Landlord's heirs,
successors or assigns.  The Security Deposit shall be security for the full and
faithful performance of all the covenants and conditions contained herein during
the Term of this Lease and any extension or renewal thereof.  The rights and
remedies reserved to the Landlord under this Lease are cumulative, and in the
event of a default by the Tenant, the Landlord shall not be required to resort
to the Security Deposit before exercising any other remedy available to Landlord
under this Lease or by law.  The Security Deposit shall be refunded 

                                     -16-
<PAGE>
 
without interest to the Tenant within ten days following the expiration of this
Lease, or any renewal or extension thereof, unless there shall be damages or
unpaid rent due Landlord, in which event the same shall be deducted by Landlord
and the remainder returned to Tenant. In no event, except when the Landlord
elects at Landlord's sole option to do so, may the Tenant set off or apply any
part of the Security Deposit against any rent owing by the Tenant to the
Landlord hereunder.

                                   ARTICLE XV

                      LIMITATION OF LIABILITY OF LANDLORD

     15.01  In the event of any alleged default of Landlord, Tenant agrees that
Tenant shall not seek to secure any claim for damages or indemnification by any
attachment, garnishment or other security proceeding against any property of the
Landlord other than the Project or property related thereto, and in the event
Tenant obtains any judgment against Landlord by virtue of an alleged default by
Landlord under this Lease, Tenant agrees that Tenant will not look to any
property of Landlord other than the Project for satisfaction of such judgment.

     15.02  Landlord shall not be liable for any damage to property of Tenant or
of others located on the Leased Premises, or for the loss of or damage to any
property of Tenant or of others by theft or otherwise.  Landlord shall not be
liable for any injury or damage to persons or property resulting from fire,
explosion, falling plaster, steam, gas, electricity, water, rain or snow or
leaks from any part of the Leased Premises or from the pipes, appliances or
plumbing works or from the roof, street or subsurface or from any other place or
by dampness or by any other cause of whatsoever nature.  Landlord shall not be
liable for any such damage caused by other tenants or persons in the Project, by
occupants of adjacent property to the Project, by other members of the public,
or caused by operation or construction of any other private or public work.  All
property of Tenant kept or stored on the Leased Premises shall be so kept or
stored at the risk of Tenant only.

     15.03  Upon any transfer of Landlord's interest in the Project, the then
transferor Landlord shall be relieved of any and all liability to Tenant under
this Lease, except for claims of Tenant against Landlord arising out of events
occurring prior to such transfer.

                                  ARTICLE XVI

                                QUIET ENJOYMENT

     16.01  Upon payment by the Tenant of the rents herein provided, and upon
the observance and performance of all the covenants, terms and conditions on
Tenant's part to be observed and performed, Tenant shall peaceably and quietly
hold and enjoy the Leased Premises for the term hereby demised without hindrance
or interruption by Landlord, subject, nevertheless to the terms and conditions
of this Lease, and subject to the restrictions and easements or other matters as
appear in Exhibit B.

                                  ARTICLE XVII

                            MISCELLANEOUS COVENANTS

     17.01  The Landlord and Tenant hereby waive trial by jury in any action,
proceeding or counterclaim brought by Landlord for possession of the Leased
Premises.  In any dispute between the parties relating to the tenancy hereby
created, the exclusive forum for any such legal action shall be the Norwalk,
Connecticut, state courthouse, if venue shall be accepted by such court, or the
nearest state courthouse to Bridgeport having jurisdiction and venue over the
matter.  Connecticut law shall apply to all state law matters arising under this
Lease.

     17.02  The waiver by Landlord of any breach by Tenant of any term, covenant
or condition herein contained shall not be deemed to be a waiver of such term,
covenant or condition or any subsequent breach of the same or any other term,
covenant or condition herein contained.  The subsequent acceptance of rent
hereunder by Landlord shall not be deemed to be a waiver of any preceding breach
by Tenant of any term, covenant or condition of this Lease, other than the
failure of Tenant to pay the particular rental so accepted, regardless of
Landlord's knowledge of such preceding breach at the time of acceptance of such
rent.  No covenant, term or condition of this lease shall be deemed to have been
waived by Landlord unless such waiver be in writing by Landlord.

     17.03  No payment by Tenant or receipt by Landlord of a lesser amount then
the monthly rent herein stipulated shall be deemed to be other than on account
of the earliest stipulated rent, nor shall any endorsement or statement on any
check or any letter accompanying any check or payment as rent be deemed an
accord and satisfaction, and Landlord may accept such check or payment without
prejudice to Landlord's right to recover the balance of such rent or pursue any
other remedy in this Lease provided.

     17.04  This Lease and the Exhibits, attached hereto and forming a part
hereof, set forth all the covenants, promises, agreements, conditions and
understandings between Landlord and Tenant concerning  the Leased Premises and
there are no covenants, promises, agreements, conditions or understandings,
either oral or written, between the parties other than those herein set forth.
No subsequent alteration, amendment, change or addition to this lease shall be
binding upon Landlord or Tenant unless reduced to writing and signed by the
party to be charged.

     17.05  If any term, covenant or condition of this Lease or the application
thereof to any person or circumstances shall, to any extent, be invalid or
unenforceable, the remainder of this Lease, or the application of such term,
covenants or condition to persons or circumstances other than those as to which
it is held invalid or unenforceable, shall not be affected thereby and each
term, covenant or condition of the Lease shall be valid and enforced to the
fullest extent permitted by law.

     17.06  If the Commencement Date is not a date certain, the Commencement
Date shall in no event be later than a time which would not violate any
applicable rule against perpetuities, determined as if all relevant lives in
being ceased as of the date of execution of this Lease.

                                     -18-

     17.07  In the event that Landlord shall be delayed in, hindered in, or
prevented from, the performance of any act required hereunder by reason of Force
Majeure, which shall mean strikes, lock-outs, labor troubles, inability to
procure materials, failure of power, restrictive governmental laws or
regulations, riots, insurrection, war or other reason of a like nature not the
fault of the Landlord and despite his good faith efforts to avoid such Force
Majeure, then performance of such act shall be excused for the period of the
delay.  Notwithstanding the foregoing, any Force Majeure shall not affect
Tenant's cancellation right in the event the Leased Premises Completion Date is
not within 180 days of the date Tenant submits its final plans, as set forth in
paragraph 19.01.

     17.08  Tenant agrees that the Landlord and Landlord's agents and other
representatives shall have the right to enter into and upon the Leased Premises
at all reasonable hours, upon reasonable notice, consistent with Tenant's
security requirements, (without notice in the case of an emergency) for the
purpose of making such repairs or alterations therein as may be necessary for
the safety and preservation the Project.  Tenant shall have the right to have a
member of Tenant's staff accompany the person making the entry on behalf of
Landlord, except in the case of an emergency.

     17.09  During the Term of this Lease, Tenant agrees to permit the Landlord
or Landlord's agents to show the Leased Premises to persons wishing to purchase
the same upon reasonable notice to Tenant and at reasonable hours.  During the
six months next prior to the expiration of the term (which term has not then
been renewed), Tenant agrees to permit the Landlord or Landlord's agents to show
the Leased Premises to persons wishing to rent the same upon reasonable notice
to Tenant and at reasonable hours.

     17.10  Tenant shall not encumber or obstruct the General Common area in the
Project, nor allow the same to be obstructed or encumbered in any manner.
Landlord shall not obstruct the entrance to the Leased Premises and shall not
unreasonably interfere with Tenant's use of the General Common Area.

     17.11  The submission of this Lease for examination does not constitute a
reservation of or option for the Leased Premises and this Lease shall become
effective only upon execution and delivery thereof by Landlord and Tenant.

     17.12  Neither party shall record this Lease, but the parties hereto agree
to execute a Notice of Lease drawn in accordance with the Connecticut statutes,
and the parties agree to execute in recordable form an agreement establishing
the specific commencement date of this Lease when the same is ascertainable.

     17.13  If there shall be one or more tenants or one or more landlords, each
tenant and landlord shall be jointly and severally liable for all of the
covenants and obligations of the Tenant and Landlord hereunder, as the case may
be, except as express provision may be elsewhere made to the contrary.

     17.14 The use of the neuter singular pronoun to refer to Landlord or Tenant
shall be deemed a proper reference even though Landlord or Tenant may be an
individual, a partnership, a corporation, or a group of two or more individuals
or corporations. The necessary grammatical

                                     -19-
<PAGE>
 
changes required to make the provisions of this Lease apply in the plural sense
where there is more than one Landlord or Tenant, or to either corporations,
associations, partnerships, or individuals, males or females, shall in all
instances be assumed as though in each case fully expressed.

     17.15  The headings, section numbers and article numbers appearing in this
Lease are inserted only as a matter of convenience and in no way define, limit,
construe, or describe the scope or intent of such sections or articles of this
Lease nor in any way affect this Lease.

                                 ARTICLE XVIII

                           SURRENDER AND HOLDING OVER

     18.01  At the expiration of the tenancy hereby created, whether by lapse of
time or otherwise, Tenant shall surrender the Leased Premises in the same
condition as the Leased Premises were in upon delivery of possession thereto
under this Lease, reasonable wear and tear and insured casualty excepted, and
Tenant shall surrender all keys for the Leased Premises to Landlord at the place
then fixed for the payment of rent, and Tenant shall inform Landlord of all
combinations on locks, safes and vaults, if any, in the Leased Premises.  Tenant
shall remove all its trade fixtures and/or, at the option of the Landlord, any
alteration or improvements installed by Tenant, before surrendering the premises
as aforesaid and shall repair any damage to the Leased Premises caused thereby.
Tenant's obligation to observe or perform this covenant shall survive the
expiration or other termination of the term of this Lease.  If Tenant fails to
remove such trade fixtures and restore the Leased Premises, then upon the
expiration or sooner termination of this Lease, and upon the Tenant's removal
from the premises, all such alterations, decorations, additions and improvements
shall become the property of the Landlord.

     18.02  Holding over with the written consent of Landlord shall be at the
Basic Minimum Annual Rent and the Additional Rent specified herein and shall
otherwise be on all terms and conditions set forth herein, except for the term,
which shall be month to month, and without any right of first refusal or options
to extend the term, lease other space and/or purchase property.  Should Tenant
withhold possession of the premises from Landlord after termination of the
within Lease, whether by lapse of time, by termination by either party as
provided herein, or in any other manner, and except in the case where the
Landlord has given written consent to holding over, the damages Tenant shall be
liable for are hereby liquidated at a monthly sum equal to one and one-half the
monthly minimum and additional rent in effect for the month immediately
preceding the holdover period, plus any items of additional rent Tenant would
otherwise be responsible for under this Lease (attorney's fees and damage to
Landlord's property, for example).

                                  ARTICLE XIX

                  WORK TO BE PERFORMED IN THE LEASED PREMISES

     19.01  The work set forth in this Article below and any plans initialed and
approved by both the Landlord and Tenant are hereby made a party of this Lease
and set forth the Landlord's responsibility with respect to work to be done in
the Leased Premises.  Upon Tenant's furnishing 

                                     -20-
<PAGE>
 
to Landlord Tenant's finish plans, Landlord shall promptly undertake the
construction of the Leased Premises and pursue the same to completion with
diligence. The date on which a certificate of occupancy is issued for the Leased
Premises, substantially complete in accordance with Tenant's finish plans is the
"Leased Premises Completion Date", which is date upon which the Additional rent
(defined in Article IV) begins to accrue. "Substantially complete" shall mean
that: (i) the carpet shall have been installed; (ii) the computer room and
telephone room floors and all mechanical/electrical to be supplied to the rooms
by Landlord shall have been installed; and (iii) all mechanical/electrical
systems and light fixtures provided by Landlord shall be working. It is
estimated that the Leased Premises Completion Date shall be 90 days from the
date Tenant furnishes Landlord with approved finish plans. Notwithstanding the
foregoing, if Landlord shall be delayed in completing work which is Landlord's
responsibility or if Landlord shall be otherwise delayed in obtaining a
certificate of occupancy for the Leased Premises, and if such delay is caused by
the failure of Tenant to provide Tenant's finish plans within a reasonable time,
the failure of Tenant to provide reasonable turn around time on architectural
decisions to be made by Tenant, or the failure of Tenant to provide items to the
Leased Premises on time which are Tenant's responsibility, then the Leased
Premises Completion Date shall be the date on which the Leased Premises would
have been ready but for the delay due to Tenant. If the Leased Premises
Completion Date shall not be within 180 days of the date Tenant has delivered
its architectural drawings, Tenant shall have the right to cancel this Lease by
giving written notice to Landlord not sooner than the 181st day and not later
than the 190th day. If Tenant shall exercise its cancellation right under this
paragraph, this Lease shall immediately come to and end by lapse of time. If
Tenant shall not exercise its cancellation right within the above time period,
the right shall expire. Notwithstanding the provisions of paragraph 1.05 and
Article IV, if the Leased Premises Completion Date shall not be on or before 150
days after Tenant has delivered its architectural drawings, for every day beyond
the 150 days until the Leased Premises Completion Date, the Basic Minimum Annual
Rent shall be abated by an additional two days beginning December 1, 1990 and
continuing for the cumulative total of the two abatements. Notwithstanding the
foregoing, if Tenant shall not delivery its architectural plans, the 180 day and
150 day periods and 181st and 190th dates set forth above shall be extended by
one day for every day of delay beyond 30 days in the delivery of the final and
complete finish plans.

     19.02  The work performed by Landlord in the Leased Premises and in the
construction of the Project shall be warranted for a period of one year from the
completion date, and Tenant shall not be responsible for repair or replacement
of said items during said one year period.  Thereafter, repair and replacement
of the aforesaid shall be an element of Additional Rent, either by Tenant's Pro
Rata Share or the full responsibility of Tenant, as otherwise provided in this
Lease.

     19.03  Tenant shall, on or before December 31, 1989, deliver to Landlord a
final architectural plan, a final ceiling plan, a final lighting plan and plan
from an electrical estimation may be made.  The architectural plan shall include
a layout for Tenant's partitions, including specifications for the partitions,
and layout for the door openings and any other openings.  Tenant shall, within
30 days after the submission of the aforementioned plans, deliver the final
electrical plan, final finish plans and all specifications, and any and all
other information as may be necessary to complete the Leased Premises, including
the flooring selection, color choices and other finish materials selection.
Notwithstanding any provision for determination of the Leased 

                                     -21-
<PAGE>
 
Premises Completion Date elsewhere set forth in this Lease, if Tenant shall fail
to submit the plans required above, within the time limits required above, the
Leased Premises Completion Date shall be accelerated by the period of delay in
submission of the aforementioned plans beyond the promised dates.

     19.04  All plans shall be reviewed by the Landlord's architect and shall
include both Exhibit D Work and Extra Work (defined in paragraph 19.05) and
shall be consistent with the design, construction and equipment of the Building.
Such plans shall show the location and extent of any excess floor loading and
all special requirements for air conditioning, plumbing and electricity, and the
estimated total electrical load.  All such plans and specifications are
expressly subject to Landlord's written approval, which Landlord will not
unreasonably withhold or delay, and Landlord shall provide prompt turnaround
time in the review of all plans.  Landlord shall bear the cost and expense of
filing such plans and specifications with the appropriate governmental agencies.

     19.05  Landlord shall bear the cost of all work set forth in Exhibit D,
attached hereto, except for the noted exceptions (the "Exhibit D Work").  Unless
the Lease is cancelled pursuant to paragraph 19.01, Tenant shall pay for the
cost of all that part, if any, of the work not set forth in Exhibit D as
Landlord's responsibility (the "Extra Work").  No allowance shall be made for
the omission of any Exhibit D Work except as specifically set forth herein.
Tenant may elect to pay for the Extra Work, if any, in equal monthly
installments beginning with the Leased Premises Completion Date and ending on
December 1, 1996, amortized at the rate of 10% per annum, or Tenant may elect to
prepay the outstanding and unpaid balance at any time during the initial Term of
this Lease, without penalty.  Notwithstanding the foregoing, if this Lease shall
terminate for any reason and if there shall remain any sums due Landlord for the
Extra Work, such sums shall become immediately due and payable upon the
termination.  Tenant may have a shower and locker room facility in its own
Leased Premises, at its own cost and expense (Extra Work).  Tenant shall have
the right to obtain bids for any extra work, or for work where an allowance has
been set, that may reasonably be performed or supplied by a contractor other
than the contractors used by Landlord for performance of the Exhibit D work.
For example, if Tenant requires a specialized partition that is integral with
the standard partitions, Landlord may require that the work be done by
Landlord's drywall contractor.  If, however, Tenant requires a special carpet,
Tenant may obtain bids for the special carpet.  Notwithstanding anything in this
article to the contrary, if the bidding shall cause any portion of the Leased
Premises construction job to be delayed, the Leased Premises Completion Date
shall be accelerated by the period of delay.  Landlord shall notify Tenant
within 10 days after Landlord becomes aware that any bidding process is
beginning to cause delay in the Leased Premises construction job.  Change orders
up to a total value of $1,000 in extra cost may be made verbally by Richard
Bankosky, Constance Galley or Ann Ericson.  Any other change order must be in
writing.

     19.06  Landlord will, subject to all the covenants, agreements, terms,
provisions and conditions of this Lease give access to the Leased Premises to
decorators and other contractors employed by Tenant for the purpose of making
improvements therein, when so long as, in Landlord's reasonable judgment, the
work to be done in the Leased Premises by Landlord as provided herein shall have
been completed to such an extent that the making of such improvements will not
interfere with or delay Landlord's performance of the remaining portion of its
work; it being understood that Tenant shall not be deemed to have entered into
occupancy of 

                                     -22-
<PAGE>
 
the Leased Premises by reason of the presence in the Leased Premises of any
decorator or other contractor. If at any time such entry shall cause disharmony,
delay or interference with Landlord's performance of the remaining portion of
the work, this license may be withdrawn by Landlord immediately upon written
notice to Tenant.

     19.07  In the event Landlord shall be delayed in obtaining delivery of any
item specially ordered for Tenant's Leased Premises in accordance with Tenant's
finish plans and if such delay shall cause a delay in Landlord's obtaining a
certificate of occupancy, the Leased Premises Completion Date shall be the date
on which Landlord would have been able to obtain a certificate of occupancy but
for the delay in obtaining the specially ordered item.  Landlord shall use best
efforts to obtain prompt delivery of all items required for completion of the
Leased Premises in time to complete the Leased Premises on time.  In the event,
however, that Landlord shall foresee difficulty in obtaining timely delivery of
any such specially ordered item referred to above, Landlord shall notify Tenant
of this condition, and Tenant shall have the option of obtaining delivery of
said item through Tenant's own source or replacing the item for which timely
delivery is not obtainable with an item with an earlier delivery date.

                                   ARTICLE XX

                                EXPANSION SPACE

     20.01  Provided that this Lease shall then be in full force and effect and
the Tenant shall not then be in default of the Lease, Tenant shall have the
right to add an additional approximately 5,000 square feet of Tenant's Net
Rentable Area to its Leased Premises (the "Expansion Space").  Tenant may only
exercise its right to add the Expansion Space under this paragraph by giving
written notice to Landlord on or before January 1, 1992.  If Tenant exercises
its right to add the Expansion Space, Landlord shall prepare the space in
accordance with Tenant's finish plans, the Exhibit D portion of the work to be
Landlord's expense and the Extra Work to be at Tenant's expense, payable upon
completion of the work.  Tenant shall provide Landlord with all architectural
plans, ceiling plans, electrical plans, lighting plans, final finishes and all
specifications and any other plans necessary to construct the Leased Premises,
within ninety days after notice of exercise of the right to expand under this
paragraph.  Upon the Expansion Commencement Date, the Tenant's Net Rentable Area
shall be adjusted by addition of the square footage for the Expansion Space, the
Basic Minimum Annual Rent for the Initial Term shall be increased by $17.80 per
square foot of Tenant's Net Rentable Area for the Expansion Space, and all other
items based on Tenant's Net Rentable Area shall be adjusted accordingly.  The
"Expansion Commencement Date" shall be the date upon which Landlord obtains a
certificate of occupancy for the space, substantially completed (as defined in
paragraph 19.01) in accordance with Tenant's finish plans, which in either case
shall be, at Landlord's election, during the 34th month through the 40th month
from the original Commencement Date (January 1, 1990).  Notwithstanding the
foregoing, in the case where the Expansion Space has not been previously fitted
up, if Tenant shall not furnish Tenant's finish plans within the time period set
forth above or the Expansion Commencement Date shall be accelerated by the
period of the delay in providing the finish plans.  If the Expansion
Commencement Date shall not be on or before the last day of the 40th month from
the original Commencement Date, and provided that Tenant has delivered its final
and complete finish plans within 90 days after notice of exercise of its right
to 

                                     -23-
<PAGE>
 
add the Expansion Space, the Basic Minimum Annual Rent for the Expansion Space
shall be abated by two days for every day beyond the last day of the 40th month
that the Expansion Commencement Date is delayed.

                                  ARTICLE XXI

                               OPTIONS TO EXTEND

     21.01  At the expiration of the Initial Term, if Tenant shall not then be
in default of the Lease, then Tenant shall have the option to extend this Lease
(the "First Option Term"), upon the same terms and conditions excepting the
provision for minimum rental, for one option term of five years, the First
Option Term to commence on expiration of the Initial Term.  The First Option
Term shall be exercised by the Tenant first giving written notice to Landlord of
Tenant's request to commence the procedure for determining fair market rent for
the First Option Term, the written notice to be given not less than sixteen (16)
months prior to the expiration of the Initial Term.  The Basic Minimum Annual
Rent for the First Option Term shall be the lesser of: (i) the Basic Minimum
Annual Rent in effect immediately prior to the commencement of the First Option
Term (adjusted to reflect the Expansion Space) annum increased by the percentage
increase in the United States Department of Labor Bureau of Labor Statistics
Consumer Price Index-All Urban Consumers-All Cities (1982-84 = 100) (the "CPI")
between the dates of October 1, 1989 and October 1, 1995; or (ii) 90% of the
fair market rent for the space on the commencement of the First Option Term.
Provided further, that if at the time for the determination of the rental
increase as herein provided the CPI is no longer published or issued, the
Landlord shall use such other index as is then generally recognized and accepted
for similar determinations of purchasing power.  Said fair market rent shall be
determined as the fair market rent for net leases on a square foot basis for
similar property located in the Town of Wilton, which comparable rates shall
apply to new leases.  Upon receipt of the notice to commence the procedure for
determining fair market rent, Landlord and Tenant shall attempt to agree upon
said fair market rent.  In the event Landlord and Tenant cannot agree upon said
fair market rent prior to fifteen months before the commencement of the First
Option Term, within fifteen days thereafter they each shall appoint a person
experienced in commercial rental appraisals to act in their behalf in arriving
at said market rent.  If the two appraisers cannot arrive at an agreement at
least thirteen months and fifteen days prior to the commencement of the First
Option Term, then the representatives shall, within fifteen days thereafter,
select and agree upon a third party who shall be the arbitrator.  The two
appraisers and the arbitrator shall then vote upon the fair market rent, and the
majority vote being controlling.  The figure upon which the vote is taken may be
the figure of either appraiser or a figure between the figures of the two
appraisers.  The vote shall be made not later than thirteen months prior to the
commencement of the First Option Term.  Notwithstanding the foregoing, the Basic
Minimum Annual Rent for the First Option Term, on a per square foot of Tenant's
Net Rentable Area basis, shall in no event be less than the Basic Minimum Annual
Rent in effect immediately preceding the commencement of the First Option Term.
If Tenant then wishes to exercise the First Option Term, Tenant may only do so
by giving written notice to Landlord not later than twelve (12) months prior to
the commencement of the First Option Term that Tenant is exercising the First
Option Term.  The Basic Minimum Rent shall be as determined as above, and all
other terms and conditions of the extension will be exactly the same as the
conditions set forth in this Lease including all provisions for additional 

                                     -24-
<PAGE>
 
rent and payments, but without, however, containing a further provision for
extension or renewal except as set forth in paragraph 21.02.

     21.02  At the expiration of the preceding, validly exercised First Option
Term, if this Lease shall then be in full force and effect and if Tenant shall
not then be in default of the Lease, then Tenant shall have the option to extend
this Lease (the "Second Option Term"), upon the same terms and conditions
excepting the provision for minimum rental, for another option term of five
years, the Second Option Term to commence on expiration of the First Option
Term.  The Second Option Term shall be exercised by the Tenant giving written
notice to Landlord of Tenant's request to commence the procedure for determining
fair market rent for the Second Option Term, the written notice to be given not
less than sixteen (16) months prior to the expiration of the First Option Term.
The Basic Minimum Annual Rent for the Second Option Term shall be 100% of the
fair market rent for the space on the commencement of the Second Option Term.
Said fair market rent shall be determined as the fair market rent for net leases
on a square foot basis for similar property located in the Town of Wilton, which
comparable rates shall apply to new leases.  Upon receipt of the notice to
commence the procedure for determining fair market rent, Landlord and Tenant
shall attempt to agree upon said fair market rent.  In the event Landlord and
Tenant cannot agree upon said fair market rent prior to fifteen months before
the commencement of the Second Option Term, within fifteen days thereafter they
each shall appoint a person experienced in commercial rental appraisals to act
in their behalf in arriving at said market rent.  If the two appraisers cannot
arrive at an agreement at least thirteen months and fifteen days prior to the
commencement of the Second Option Term, then the representatives shall, within
fifteen days thereafter, select and agree upon a third party who shall be the
arbitrator.  The two appraisers and the arbitrator shall then vote upon the fair
market rent, and the majority vote being controlling.  The figure upon which the
vote is taken may be the figure of either appraiser or a figure between the
figures of the two appraisers.  The vote shall be made not later than thirteen
months prior to the commencement of the Second Option Term.  Notwithstanding the
foregoing, the Basic Minimum Annual Rent for the Second Option Term, on a per
square foot of Tenant's Net Rentable Area basis, shall in no event be less than
the Basic Minimum Annual Rent in effect immediately preceding the commencement
of the Second Option Term.  If Tenant then wishes to exercise the Second Option
Term, Tenant may only do so by giving written notice to Landlord not later than
twelve (12) months prior to the commencement of the Second Option Term that
Tenant is exercising the Second Option Term.  The Basic Minimum Rent shall be as
determined as above, and all other terms and conditions of the extension will be
exactly the same as the conditions set forth in this Lease including all
provisions for additional rent and payments, but without, however, containing a
further provision for extension or renewal.

                                  ARTICLE XXII

                               CANCELLATION RIGHT

     22.01  If this Lease shall then be in full force and effect and if Tenant
shall not then be in default of the Lease, then Tenant shall have the right to
cancel and terminate this Lease, the effective date of the termination to be the
end of any calendar month from December 31, 1994 through and including November

                                     -25-
<PAGE>
 
delivering to Landlord, not less than twelve months prior to the effective date
of the termination, written notice of Tenant's exercise of this cancellation
right, which shall include the effective date of the termination, and payment of
or a letter of credit for the following items: (i) the unamortized balance all
tenant improvement work (Exhibit D Work and Extra Work) for construction of the
original Leased Premises (defined in paragraph 19.05); (ii) the unamortized
balance of the Rent Reduction Amount; (iii) the unamortized balance of the
$45,000 moving allowance; (iv) the unamortized balance of the amounts expended
by Landlord for the payment of Tenant's lease obligations on its 295 Westport

1990); and (v) the unamortized cost of all tenant improvement work (Exhibit D
Work and Extra Work) for the construction of the Expansion Space. Tenant's
written notice of exercise shall not be valid unless the payments set forth in
items (i) through (v) above, or an irrevocable letter of credit therefor,
accompany the notice or have been delivered to Landlord prior to the notice. If
Tenant shall elect to deliver an irrevocable letter of credit, the letter shall
be drawn on a Connecticut or national bank having an office in Bridgeport,
Connecticut, callable by Landlord, or Landlord's assignee, at said Bridgeport
office, upon the effective date of the termination and any consecutive business
day thereafter, the letter to expire not sooner than 60 days after the effective
date of the termination. Landlord shall provide an itemized statement of the
cost of the item (i) tenant improvement work within 120 days of completion of
the Leased Premises and shall provide an itemized statement of the cost of the
item (v) tenant improvement work within 120 days of the Expansion Space
Commencement Date. The item (ii) Rent Reduction Amount shall be the amount of
11/12ths multiplied by $17.80 per annum per square foot of Tenant Net Rentable
Area on the original Leased Premises. The amortization of items (i) through (iv)
shall be calculated such that the items are completely amortized on the basis of
equal monthly installments, beginning January 1, 1991 and ending on December 31,
1996, at the rate of 10% per annum. The "unamortized balance" in items (i)
through (v) above shall mean the unamortized balance as of the effective date of
the termination. The amortization of item (v) shall be calculated in the same
manner as items (i) through (iv), except that the amortization period for item
(v) shall be from the Expansion Commencement Date to December 31, 1996. If
Tenant shall exercise its right of cancellation under this Article, the Lease
shall come to an end by lapse of time, as if the Initial Term expired on the
effective date of the termination.

                                 ARTICLE XXIII

                        RIGHT OF FIRST REFUSAL TO LEASES

     23.01  Provided that this Lease shall then be in full force and effect and
the Tenant shall not then be in default of the Lease, after the sooner of the
initial rent up of the building or January 1, 1991, Tenant shall have the right
of first refusal to any lease of other space in the building.  Landlord shall
notify Tenant when Landlord becomes aware that space will become available in
the building after its initial rent up, and Landlord shall copy Tenant on all
initial proposals to prospective tenants for space available in the building
after the initial rent up.  Landlord shall also notify the Tenant in writing of
the terms of any bona fide offer to lease space to which Tenant's right of
refusal applies, and Tenant shall have five (5) business days after receipt of
said notice of terms of rental to notify Landlord of its acceptance of said
rental terms, in writing.  If Tenant shall not exercise its right of refusal
within the five business day time 

                                     -26-
<PAGE>
 
period, Landlord shall be free to rent the space which was subject to the offer
at the rent set forth in the offer or at a higher rent, and Tenant's refusal
right shall be of no further force and effect with respect to any space that
Landlord so rents, except that if such Lease shall terminate prior to the
termination of Tenant's Lease, Tenant's right of refusal shall reapply to the
space whose lease terminated. If Landlord wishes to rent the space at a lower
rent, Landlord must again notify Tenant of the terms of any such bona fide offer
acceptable to Landlord and the above process shall be repeated. If the
notification of bona fide offer to Tenant shall not be in the form of a formal
lease and if Tenant shall accept the offer, Tenant shall promptly execute a
formal lease in accordance with the accepted offer (the offer not necessarily
addressing legal terms such as subordination, casualty and eminent domain, for
example). If Tenant shall fail to execute the proffered lease, Landlord may give
notice to Tenant that unless Tenant delivers the executed lease within five days
to Landlord, Landlord intends to rent the space to another party. If Tenant
shall fail to deliver the executed lease within such five day period, Landlord
shall be free to rent the space on the terms set forth in such lease to another
party, and upon such renting, the space shall be free of Tenant's right of
refusal.

                                  ARTICLE XXIV

                         RIGHT OF FIRST REFUSAL TO SALE

     24.01  If this Lease shall then be in full force and effect and if Tenant
shall not then be in default of the Lease, then during the Term of this Lease,
Tenant shall have the right of refusal to a sale of the Project, under the
following terms and conditions.  Provided that Tenant's right of refusal shall
be in full force and effect and in the event the Landlord shall receive a bona
fide offer to purchase the Project upon terms and conditions satisfactory to
Landlord, then Landlord shall give Tenant written notice of the terms and
conditions of the bona fide offer, which may include other real estate in
addition to the Exhibit B property.  Tenant shall have the right to purchase the
Project upon the same terms and conditions presented in Landlord's notice.  If
Tenant wishes to exercise the right to refusal to sale, Tenant must give written
notice of its exercise of the right and acceptance of the terms and conditions
set forth in Landlord's notice within fifteen days of the date of Landlord's
notice to Tenant.  If Landlord's notice to Tenant shall be in the form of a
proposed formal contract, Tenant's acceptance shall be accompanied by return of
the contract with Tenant's execution and the payment of any deposit, if and when
required under the terms of the contractor.  If said contract is not presented
at the time of Landlord's notice of offer to Tenant, Tenant shall sign and
return the formal contract embodying the terms and conditions of the offer
within fifteen days of presentment of same by Landlord.  Notwithstanding any
time period for closing in the offer received by Landlord.  If Tenant shall
exercise its right to purchase under this paragraph, Landlord may require the
closing of title to be not later than sixty days from the signing of the
contract.  If Tenant shall fail to exercise the right of refusal to sale with
respect to any notice of bona fide given by Landlord, Landlord shall be free to
sell the Project to any party at any later date at a price at least as high as
that in the offer which Tenant failed to accept.  The rights of Tenant under
this paragraph shall be subordinate to any bona fide mortgage on the Project,
and such rights shall not be applicable to a foreclosure of the Project or deed
in lieu thereof and shall not survive the passing of title under such
foreclosure or deed in lieu of foreclosure.  The right of refusal under this
paragraph shall also not be applicable in the case of a transfer of the Project
or an interest therein to a corporation, a partnership or another 

                                     -27-
<PAGE>
 
entity in which the original Landlord or an immediate family member or members
of the original Landlord retain a majority interest. If Tenant shall accept the
terms and conditions of Landlord's notice but shall thereafter default in the
obligations of Tenant under this paragraph or in the obligations of purchaser
under the contract signed by Tenant, Tenant's right to refusal of sale shall
terminate.

                                  ARTICLE XXV

                                 MISCELLANEOUS

     25.01  Upon the Leased Premises Completion Date and occupancy of the Leased
Premises by Tenant, if this Lease shall then be in full force and effect and if
Tenant shall not then be in default of this Lease, then Landlord shall pay to
Tenant $45,000 as a moving allowance.  Landlord agrees to make the $45,000
payment on the date Tenant moves into and occupies the Leased Premises.

     25.02  All construction work on the building lobby shall be complete upon
the completion of the Leased Premises construction, except that the art work for
the lobby may not then be installed.  Tenant shall have reasonable input on the
decor and art work for the lobby and any common corridors on the second and
third floors.

     25.03  Unless incidental to an office use, Landlord shall not, without
Tenant's approval, lease the remaining space in the building for either of the
following uses: a restaurant; or the retail sale of goods to the public on site.
The intent of this paragraph is that a permitted use of other space would be
incidental to an office use.  For example, a cafeteria within an office for the
use of the employees of the office would be permitted.  Landlord shall also not
rent other space in the building for any use which would interfere with the
operation of Tenant's business or be incompatible with uses appropriate for a
first class office building in Fairfield County.

     25.04  Landlord shall mark ten parking spaces near the front door of the
building as visitor parking.

     25.05  Tenant shall have the right to approve or disapprove of the design
of the signage for the tenants on the monument which is to be for the building
address, as set forth in paragraph 5.05, which approval shall not be
unreasonably withheld by Tenant.

     25.06  Subject to Landlord's approval, which shall not be unreasonably
withheld, and any required governmental approval (such as Wilton  zoning
approval), Tenant shall have the right to place a small satellite dish on the
roof of the Leased Premises building.  Any such dish shall be for the use of
Tenant only and shall not be used as a utility transmission or reception
station.

     25.07  Landlord shall complete the Project, at Landlord's sole cost as
expense, in accordance with the plans entitled: "Wilton Office Building, 47
Danbury Road, Route 7, Wilton, Connecticut, Prepared for R.D. Scinto by Kasper
Associates/Design Collaborative Architects, Sheet SP-4 (landscape plan - last
revised 1/6/89, Sheets A-1, A-2 & A-3 (architectural plans - last revised
2/24/89) and Sheets A-5 & A-6 (architectural plans - last revised 8/28/89)".

     25.08  If and so long as this Lease shall then be in full force and effect
and if Tenant shall not then be in default of this Lease, Landlord shall
reimburse Tenant for any rental liability Tenant may incur on its existing
premises at 295 Westport Avenue, Norwalk for the period from January 1, 1990 to
October 7, 1990, provided further that Landlord's liability under this paragraph
shall not exceed $23,657 per month, with partial months to be pro rated.
Payments shall commence January 1, 1990 to continue on the first day of each
month thereafter.  The reimbursement payments shall be made payable directly to
Tenant.  Landlord shall promptly provide Tenant with an irrevocable letter of
credit to secure Landlord's obligation under this paragraph.  In the event that
any draw shall be made on the letter of credit, in accordance with its terms,
and in the further event that Landlord's payment was made too late to be
credited for the month in which a draw was made, Tenant shall promptly reimburse
Landlord for any overpayment by reason of Tenant receiving both a payment from
Landlord and a draw on the letter of credit for any particular month.

     This agreement shall inure for the benefit and be binding upon the parties
hereto, their respective heirs, representatives, successors and assigns, except
where provided to the contrary by express provisions contained herein.

     IN WITNESS WHEREOF, the parties have hereunto set their hands and seals as
of the day and year first above written.

SOFTWARE LTD., a Delaware corporation ("Tenant").

                               R E C I T A L S:
                               - - - - - - - --

     A. Landlord and Tenant entered into that certain Office Building Lease

     NOW, THEREFORE, in consideration of the foregoing Recitals and other good
and valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, Landlord and Tenant agree as follows:

         1.  RECITALS; CAPITALIZED TERMS; CAPTIONS. The Recitals set forth
             -------------------------------------

"Lease." The Paragraph headings are for convenience of reference only, do not
define or construe the contents of such paragraphs and shall be ignored in any
construction thereof.

         2.  EXTENSION OF TERM. The Term of the Office Lease is hereby extended
             -----------------
for a period of five (5) years from January 1, 1996 through December 31, 2000
(the "Extension Period"), unless sooner terminated as provided in the Lease,
upon all of the same terms, covenants and conditions as set forth in the Office
Lease, except as modified hereby.

         3.  MODIFICATION OF PREMISES. Effective as of January 1, 1996, (the
             ------------------------
"Effective Date") the Office Lease is hereby amended to modify the Premises from
the Original Premises to that portion of the Original Premises which the parties
agree consists of 10,552 rentable square feet as depicted on Exhibit A attached
hereto and made a part hereof (the "Modified Premises"). From and after January

         ------------------------------
herein or elsewhere in the Lease to the contrary, Landlord and Tenant
acknowledge that when the Premises are modified from the Original Premises to
the Modified Premises, the Surrendered Space will "share" an electric meter and
panel with the Premises, and Landlord or the tenant of the Surrendered Space and
Tenant will be required to share, on an equitable basis, the electric costs
associated with the Premises and the Surrendered Space. Initially such parties
shall share the cost on a square footage basis, that is, initially eighty-seven
and 24/100 percent (87.24%) to the Premises and twelve and 76/100 percent
(12.76%) to the Surrendered Space, as modified from time to time if the Premises
shall be expanded to include some or all of the Surrendered Space pursuant to
Paragraph 8 hereof or otherwise. The parties further agree, however, that Tenant
may utilize an electric load which may be substantially greater than the
electrical load utilized at the Surrendered Space, and, therefore, a pure "pro
rata" basis may not equitably apportion the amount to each space. In such event,
the parties shall, in good faith, determine a reasonable allocation based upon
the electrical loads each party utilizes.

     7.  CAP ON EXPENSES.  Notwithstanding anything in the Lease to the
         ---------------
contrary, for the purpose of computing Additional Rent under the Lease only, the
amount of Expenses for Adjustment Years 1996, 1997, 1998, 1999 and 2000 which
shall be payable by Tenant shall be subject to the following limitation:
Expenses payable by the Tenant for Adjustment Year 1996 (if any) shall not
exceed an amount equal to $5.40 per rentable square foot of the Premises.
Thereafter for Adjustment Years 1997, 1998, 1999 and 2000 (the "Capped Years"),
Tenant's expense Adjustment (hereinafter defined) with respect to Expenses (or
components of Expenses) which are not "Uncontrollable Expenses," shall not
increase by more than five percent (5%) over the prior Adjustment Year during
the Capped Years on a cumulative compounding basis. The capped amount of
Expenses for any Capped Year is herein referred to as the "Capped Expense
Amount." The portion of the Expense Adjustment attributable to Expenses (or
components of Expenses) which are Uncontrollable Expenses (as hereinafter
defined) shall not be capped. "Uncontrollable Expenses (including uncontrollable
components of Expenses)" shall mean: the cost of snow removal, the cost of road
salt, the cost of insurance premiums required to be carried by Landlord
hereunder, the cost of internal and external common area utilities, including
electricity, water and gas, supplies and union wages for both direct employees
and employees of contractors.

     8.  RIGHT OF FIRST OFFER. Landlord hereby grants to Tenant the continuing
         --------------------
right of opportunity ("Right of Opportunity"), during the Extension Period of
the Lease to lease the Surrendered Space as depicted on and described in Exhibit
C attached hereto and made a part hereof (which is referred to hereinafter as
the "Opportunity Premises"), subject to the terms and conditions hereinafter set
forth.

   Prior to entering into the negotiation of any lease with any tenant prospect
for any part or all of the Opportunity Premises (such portion which Landlord
intends to lease to any such tenant prospect at any time being the "Offered
Premises") during the Extension Period of the Lease, so long as Tenant shall not
be in Default under this Lease, Landlord shall notify Tenant in writing of the
business and economic terms (including, without limitation, the proposed term of
the tenancy) upon which Landlord would be willing to lease the Offered Premises
to such tenant

                                       7
<PAGE>
 
prospect, and Tenant shall have the right for a period of ten (10) calendar days
from and after the giving of such notice within which to notify Landlord that it
will lease the Offered Premises on the terms and conditions as contained in
Landlord's notice and other terms and conditions of the Lease not in conflict
with the terms in the notice. Provided, however, during the period from January
1, 1996 through June 30, 1996, if Tenant shall exercise its Right of Opportunity
to lease the Offered Premises, the Base Rent shall be at the then applicable
rates for the applicable periods set forth in Paragraph 4 above per square foot
of rentable area of such Offered Premises, and the Landlord's contribution
toward the cost of tenant improvements in such Offered Premises will be an
amount equal to Eleven and 82/100 Dollars ($11.82) per rentable square foot of
Offered Premises for any Offered Premises leased in January 1996, and reduced by
$.1970 each month thereafter through June, 1996, so that for space leased during
February, 1996, the amount would be Eleven and 62/100 Dollars ($11.62), for
space leased in March, 1996, the amount would be Eleven and 43/100 Dollars
($11.43) and so forth. If Tenant shall timely elect to lease the Offered
Premises, then Landlord and Tenant shall proceed in good faith to finalize such
lease of the Offered Premises. If Tenant elects to lease the Offered Premises,
the Offered Premises shall be added to the Lease and become Premises by an
amendment to the Lease and shall be governed by the terms and conditions of this
Lease as modified or supplemented by the terms in the notice or the alternate
rent and construction contribution provision, if applicable, as aforesaid. If
Tenant fails to notify Landlord in writing that it will accept the Offered
Premises within the prescribed ten (10) calendar day period, Tenant's right to
lease such Offered Premises shall be terminated and Landlord may thereafter
lease such Offered Premises to such other tenant prospect free of the rights of
Tenant, except as provided in the next sentence. If Landlord elects to offer the
Offered Premises to such tenant prospect on terms economically less favorable
(from Landlord's perspective) by ten percent (10%), then Landlord shall again
offer the Offered Premises to Tenant on such less favorable (from Landlord's
perspective) economic terms in accordance with the provisions in this
grammatical paragraph.

   Tenant may not elect to lease less than all of the Offered Premises described
in any notice from Landlord to Tenant concerning the Right of Opportunity. In
addition, Tenant's right to exercise the Right of Opportunity in any instance
and the commencement of the term for any Offered Premises shall be conditioned
upon satisfaction of the following terms and conditions: (a) at the time of the
exercise of the Right of Opportunity this Lease shall be in full force and
effect, and Tenant's right to possession of the Premises shall not have been
terminated, and Tenant shall not be in Default hereunder, and, at Landlord's
option, at the time the term of the lease for the related Offered Premises
commences, the Lease shall be in full force and effect and Tenant's right to
possession of the Premises shall not have been terminated, and Tenant shall not
be in Default hereunder; (b) at the time of the exercise of the Right of
Opportunity and, at Landlord's option, at the time the term of the lease for the
related Offered Premises commences, the original Tenant named herein or an
affiliate of Tenant as described in Section 42a of the Office Lease (a "Tenant
Affiliate") shall be occupying all of the Rentable Area of the Premises, and
such Tenant shall not have assigned the lease or sublet any portion of the
Premises other than to a Tenant Affiliate, it being agreed that the Right of
Opportunity granted hereby is personal to the named Tenant or a Tenant
Affiliate; (c) the term of the lease for the Offered Premises shall commence on
the date set forth in the opportunity notice given with respect to such Offered
Premises; (d) in the event Landlord shall be unable to tender possession of any
Offered Premises

                                       8
<PAGE>
 
to Tenant upon the commencement of the term thereof, Landlord shall not be
subject to any liability on account thereof and the failure to do so shall not
affect the validity of the Lease or the obligations of Tenant under the Lease or
the lease of the Offered Premises by Tenant, or be construed to extend the term
as to such Offered Premises, or the Term of the remainder of the Premises, but
Rent shall not commence with respect to such Offered Premises until Landlord
tenders possession thereof to Tenant; and (e) Tenant shall accept possession
from Landlord of all Offered Premises in their "as is" condition as of the date
upon which the term of the lease for such Offered Premises commences unless
specifically provided to the contrary in the pertinent opportunity notice.

     9.  WORKLETTER APPLICABLE TO MODIFIED PREMISES. Tenant acknowledges and
         ------------------------------------------
agrees that it is leasing the Modified Premises in "as is" condition except as
provided in the Modified Premises Workletter attached hereto as Exhibit B and
made a part hereof (the "Modified Premises Workletter"), and Landlord shall have
no obligation to provide or pay for or reimburse Tenant for any improvements to
the Modified Premises, except as provided in the Modified Premises Workletter.
The Modified Premises shall be improved pursuant to and in accordance with the
provisions of the Modified Premises Workletter.

     10. REAL ESTATE BROKERS. The parties agree that Stein & Company Investor
         -------------------
Services, Inc. and Julien J. Studley, Inc. are the only brokers with whom the
parties have dealt in connection with this First Amendment and the modification
of Premises and the extension of the Term of the Extension Period, and whose
commissions, if any, shall be paid by Landlord pursuant to separate agreement,
and each of the parties hereto agrees to indemnify and hold the other (and in
the case of Landlord, its beneficiaries), and their affiliates and the
respective partners, shareholders, directors, officers, agents and employees of
each of the foregoing harmless from all damages, liability and expense
(including reasonable attorneys' fees) arising from any claims or demands of any
other broker or brokers or finders for any commission alleged to be due any such
broker or brokers or finders in connection with participating with the
indemnifying party in effecting this First Amendment and the modification of
Premises and the extension of the Term for the Extension Period in violation of
the indemnifying party's representation above or otherwise claiming by, through
or under such indemnifying party.

         ---------------------------------------------

Section:

               Notwithstanding any of the foregoing, Tenant shall not be
               obligated to subordinate its interest in the Lease pursuant to
               any of the foregoing provisions to any new Mortgagee after the
               date hereof, unless such new Mortgagee requesting such
               subordination executes a non-disturbance agreement providing that
               if there is a foreclosure of such Mortgage and no Default then
               exists (a) such Mortgagee cannot make Tenant a party defendant to
               such foreclosure or termination nor in any other way foreclose
               Tenant from its rights, evict Tenant, disturb Tenant's possession
               under the Lease or

                                       9
<PAGE>
 
               terminate or disturb Tenant's leasehold estate or rights under
               the Lease, subject, however, to the terms of the Lease, and (b)
               the Lease shall continue as a direct lease between Mortgagee and
               Tenant (any such agreement or any agreement of similar import,
               from any Mortgagee being hereinafter called a "Non-Disturbance
               Agreement"), provided that such Non-Disturbance Agreement may
               contain such other terms and conditions as are contained in the
               customary form of non-disturbance agreement of any such Mortgagee
               (provided that such other terms and conditions and such customary
               form will not materially adversely change the rights and
               obligations of Tenant under the Lease), and Tenant may be
               required to execute such Non-Disturbance Agreement prior to its
               execution by the Mortgagee.

</TABLE>

<PAGE>
 
250, 2201 Waukegan Road, Bannockburn, Illinois 60015, or at such the agent or at
such other place as Landlord may from time to time designate in writing.

         Any rent (whether Base Rent, Additional Rent or other rent or other
amount provided herein as may be due to Landlord [collectively sometimes
referred to as "rent"]) or other amount due from Tenant to Landlord under this
Lease which is not paid promptly when due shall, at Landlord's mortgagee's
option, either (i) bear interest from the date due until the date paid at the
Default Rate as specified in Landlord's mortgagee's Substitute (Mortgage) Not
dated September 1, 1983 or (ii) be subject to a five percent (5%) late charge
("Late Charge") upon the total of Base Rent and Additional Rent due also as
specified in the aforesaid Substitute (Mortgage) Note. Partial payment of
monthly rent shall be construed to be first applied on account of Operating
Express and Taxes and, thereafter, toward Base Rent and other Additional Rent.
The Late Charge shall apply if Tenant has failed to pay such rent or other
amount in a timely manner for any two (2) months within a calendar year during
the term hereof and if Landlord's mortgagee does, in fact, impose the full five
percent (5%) Late Charge or a lesser sum for such month in which Tenant shall
not have paid rent on or before the first day of the month. In such event, then
all of Tenant's late payments shall likewise be subject to a Late Charge in a
like percentage or proportionate sharing less any interest as shall have been
paid by Tenant pursuant to (I) above for such months. The payment, however, of
such interest or Late Charge shall not excuse or cure any default by Tenant
under this Lease. The covenants herein to pay rent (whether Base Rent,
Additional Rent or other rent) and other amounts which may become due hereunder
shall be independent of any other covenant set forth in this Lease.

5.       ADDITIONAL RENT ADJUSTMENT FORMULA (AND DEFINITIONS).

         To the amount of Base Rent as is set forth in Section 4 above shall be
added such additional amounts as are hereinafter set forth in its Section 5 and
in Section 6.

         For the purpose of Section 5 and 6, the following words and phrases
shall have the following meanings:

DEFINITIONS

         "Adjustment Date" shall mean January 1 following the commencement date
of the Term and each January 1 thereafter falling within the Term.

         "Base Year" shall mean January 1 following the commencement date of the

Statistics shall be substantially revised an adjustment shall be made in such
revised index which would produce results equivalent, as nearly as possible, to
those which would have been obtained if the Consumer Price Index had not been so
revised. If the 1982-84 average shall no longer be used as an index of 100, such
change shall constitute a 

                                      12
<PAGE>
 
substantial revision. If the Consumer Price Index shall become unavailable to
the public because publication thereof is discontinued or is otherwise
unavailable, Landlord shall substitute therefor a comparable index based upon
changes in the cost of living or purchasing power of the consumer dollar
published by any other governmental agency or, if no such index shall be
available, then a comparable index published by a major bank or other financial
institution or by a university or a recognized financial publication or
authority.

wages, salaries or other compensation paid to any employees above the grade of
"building manager", or "property manager" (i.e., the person who is the highest

recoups, by way of setoff, reduction of recovery allowed, or otherwise.

         "Per Square Foot Operating Expenses" shall mean the amount of Operating
Expenses for any calendar year divided by 105,720 square feet (the Rentable Area
of the Building).

         "Per Square Foot Taxes" shall mean the accrued amount of Taxes for
which payment will be due for any calendar year divided by 105,720 square feet
(the Rentable Area of the Building), whether or not such payment shall actually
be paid during such year.

         "Taxes" shall mean any and all federal, state, county, local
municipality, or other political subdivision, authority, agency or taxing body

and apparatus located therein or used in connection therewith including, without
limitation, real estate taxes, personal property taxes, sewer rents, water
rents, special assessments, transit or transit district taxes or assessments,

rental received for use and occupancy of any or all of the Building and the
Property, and including any rental or similar taxes levied in lieu of, or in
addition to, general real and/or personal property taxes. If a change occurs in
the method of taxation during the Term which change shall result in whole or in
part in the substitution of any such taxes, or any other assessment, for any
Taxes, above defined, such substituted taxes or assessments shall be included in
the Taxes. For purposes hereof, if taxes are accessed or become a lien during
one year, but are due for payment or paid in a subsequent year,

were assessed or became a lien; provided however, that to the extent that a 
then-current year's reserve or escrow has under or over-estimated the 
then-current year's taxes, the net adjustment, either additional or credit, may
constitute Taxes or a credit to Taxes, respectively, in the year following the
then-current year. It is understood the real estate tax is escrowed each month
in an amount equal to one-twelfth of the estimated tax for the then-current
calendar year so that, by December 31st of each year, an amount is reserved

payable until the calendar year subsequent to the then-current year. The sum of
all such monthly reserved amounts shall be considered as a part of Taxes for
each then-current calendar year. There shall be included in Taxes for any year
the amount of all fees, costs and expenses, including attorneys' fees, paid by
the Landlord during, or relative to, such year as pertain to seeking or
obtaining reductions in or refunds of real estate taxes. Taxes in any year shall

payments for utilities, however denominated, to the extent, and if, the same are
included in Operating Expenses; (iii) any special assessments for public

ADDITIONAL RENT FORMULA

         (i)   Taxes.

         The Tenant shall pay to the Landlord, as Additional Rent, the amount of
Taxes as defined in this Section ("Taxes") equal to that proportion as the
Rentable Area of the Premises bears to the Rentable Area of the Building (such
proportion hereinafter being called "Tenant's Proportion") for the Base Year and
each Subsequent Year. The amount of Taxes, attributable to the Base Year and to
Subsequent years, shall be the amount accrued during any such year, even though
the payment date for such taxes may be in a different year or years. Such sum
shall be paid in such monthly installments as shall be reasonably estimated by
Landlord.

                                      15
<PAGE>
 
         If the tax year for real estate taxes shall be changed by the
applicable governmental authority and shall result in the payment by the
Landlord in one calendar year of taxes which relate to more than one calendar
year, then, notwithstanding anything to the contrary contained in this Lease,
for purposes of determining the Taxes for such calendar year, such amount of
Taxes paid shall be adjusted to an amount which is equivalent to a one-year
payment of Taxes.

         In the event that Property is not assessed as fully improved for the
Base Year, then, for the purposes of Sections 5 and 6 of this Lease the Real
Estate Taxes payable in such year shall be borne by the tenants based upon the
assessment of the Property in the following manner: As to the land portion of
the assessment, Tenant shall pay Tenant's Proportion thereof. As to the building
improvement portion of the assessment, Tenant shall pay Tenant's Proportion
unless it shall be shown that the Assessor limited its assessment to only the
Premise of Tenant or to a lesser area than the Rentable Area of the Building, in
which event Tenant shall pay its equitable share based upon the composition
assessment.

         (ii)  Operating Expenses.

         The Tenant shall pay to the Landlord, as Additional Rent, Tenant's
Proportion of the amount of Operating Expense for the Base Year and each
Subsequent Year, and such sum shall be paid in such monthly installments as
shall be reasonably estimated by the Landlord.

         If any Project Operating Expense, although paid in one year, relates to
more than one calendar year, at the option of Landlord such Operating Expense
may be proportionately allocated among such related calendar years.

         In the event that, during all or any portion for the Base Year or any
Subsequent year, the Building is not fully rented and occupied, Landlord shall
make an appropriate adjustment of Operating Expense for such year, employing
sound accounting and management principles, to determine the Operating Expenses
that would have been paid or incurred by Tenant had the Building been fully
rented and occupied and the amount so determined shall be deemed to have been
the Operating Expenses for such year.

         (iii) Cost of Living Increase.

               (Applicable only if Option B, Section 42 (d) is exercised by
Tenant).

         In the event that the Consumer Last Index at January 1st for any
Subsequent year shall be greater than the Consumer Price Index at January 1st of
the Base year, Tenant shall pay to the Landlord, as Additional Rent, an amount
equal to thirty-three and one-third percent (33-1/3%) of the percentage of
increase by which the Consumer Price Index at January 1st of such Subsequent
year exceeds the Consumer Price Index at January 1st of the Base Year (said
product shall be referred to herein as the "Cost of Living Increase") and then
multiplied by the aggregate amount of the Base Rent and Additional Rent for the
prior calendar year as finally adjusted.

                                      16

         (iv)  Triple Net Lease.

         Notwithstanding any provisions of this Lease which may appear to be in
conflict herewith, the parties acknowledge and agree that this Lease is intended
to be what is commonly known in the real estate industry as a "triple net" or
"net-net-net" lease; that is, in addition to Base Rent, Tenant is obligated to
pay Landlord, as Additional Rent, Tenant's Proportion of Operating Expenses and
Taxes, as defined.

6.       ADDITIONAL RENT ADJUSTMENT PAYMENT.

         Effective as of each Adjustment Date, and at the time for the payment
of each monthly installment of Base Rent thereafter until the next Adjustment
Date, Tenant shall pay, as Additional rent, an amount equal to 1/12 of the
product of (a) the Rentable Area of the Premises, as specified above, multiplied
by (b) the sum of: (1) the amount of the estimated Per Square Foot Operating
Expenses for the Subsequent Year in which such Adjustment Date falls, plus (2)
the amount of the estimated Per Square Foot Taxes for the Subsequent Year in
which such Adjustment Date falls, plus (3) an amount equal to the product of :
thirty-three and one-third percent (33-1/3%) of the percentage increase, if any,
in the Consumer Price Index for the month of the Adjustment Date over the
Consumer Price Index for January of the Base Year, multiplied by the annual rate
of monthly Base Rent and Additional Rent for the prior calendar year as finally
adjusted divided by the Rentable Area of the Premises.

         For purposes of calculating Taxes, Operating Expenses and the Consumer
Price Index for any Subsequent Year, as provided in the preceding paragraph,
Landlord ;may make reasonable estimates, forecasts or projections (hereinafter
the "Projections") of Taxes, Operating Expenses and changes in the Consumer
Price Index for such Subsequent Year. On or about March 1st following each
adjustment Date, Landlord shall deliver to Tenant a written statement (i)
setting forth the Projections of Operating Expenses, Taxes and changes in the
Consumer Price Index for the Subsequent Year in which such Adjustment Date
falls, and (ii) providing a calculation of the Additional Rent which became
effective retroactive to, and as of, said Adjustment Date and until the next
Adjustment Date; provided, however, that the failure of Landlord to provide any
such statement shall not relieve Tenant from its obligation to continue to pay
monthly Base Rent and Additional Rent at the rate then in effect under this
Lease, and when Tenant receives such statement from Landlord, Tenant shall pay
Additional Rent reflected thereby effective retroactively to the related
Adjustment Date.

         On or about March 1st following the end of each Subsequent Year, or at
such later time as Landlord shall be able to determine the actual amounts of
Taxes, Operating Expenses and the Consumer Price Index for the Subsequent Year
last ended, Landlord shall notify Tenant in writing of such actual amounts. If
such actual amounts exceed the Projections for such Adjustment Year, then Tenant
shall, within thirty (30) days after the date of such written notice from
Landlord, pay to Landlord the amount of excess of the Additional Rent payable
for the Subsequent Year last ended based upon the actual Taxes, Operating
Expenses and the Consumer Price Index for such year over the total Additional
Rent paid by Tenant on account based on the Projections during and for such
Subsequent Year last ended. The obligation to make such 

                                      17
<PAGE>
 
payment shall survive the expiration or earlier termination of the Lease. If the
Additional Rent paid by Tenant during such Subsequent Year based upon the
Projections exceeds the amount payable for such year based upon the actual
Taxes, Operating Expenses and the Consumer Price Index for such Subsequent Year,
then Landlord shall credit such excess to installments of Additional Rent which
shall become payable after the date of Landlord's notice until such excess has
been exhausted or, if this Lease shall expire or terminate prior to full
application of such excess, Landlord shall pay to Tenant the balance thereof not
theretofore applied against Additional Rent within thirty (30) days after
expiration or termination. No interest or penalties shall accrue on any amounts
which Landlord is obligated to credit or pay to Tenant by reason of this Section
unless not credited as aforesaid or paid to Tenant within thirty (30) days after
expiration or termination.

         The annual determination and statement of Taxes, Operating Expenses and
the Consumer Price Index shall be prepared in accordance with the income tax
basis of accounting and otherwise in accordance with generally accepted
accounting principles. Tenant shall have the right, at its sole cost and
expense, to inspect Landlord's accounting records relative to Taxes, Operating
Expenses and the Consumer Price Index at Landlord's accounting office during
normal business hours upon reasonable notice at any time within sixty (60) days
following the furnishing by Landlord to Tenant of such statement. Unless Tenant
shall take written exception to any item within such sixty (60) day period, such
statement shall be considered as final and accepted and conclusive upon the
Tenant. If Tenant makes a timely written exception, a certification as to the
proper amount of Additional Rent shall be made by an accounting firm selected by
Tenant from the twenty-five largest independent certified public accounting
firms in Chicago, as designated in the last available Crain's Chicago Business
Annual Survey of Accounting Firms, provided same has not performed work for
Tenant or its affiliates for the three (3) years immediately preceding the date
of the exception notice, which certification shall be final and conclusive.
Tenant agrees to pay the cost of such certification unless it is determined that
Landlord's presentation or determination of the aggregate amount of the Taxes,
Operating Expenses and the Consumer Price Index for the year was in error by
more than three percent (3%).

         In the event of the termination of this Lease by expiration of the Term
or for any other cause or reason whatsoever prior to the determination of the
rental adjustment as hereinabove set forth, Tenant's agreement to pay Base Rent,
Additional Rent, other rent and all other sum or sums due or which may become
due to Landlord up to the time of and upon or pursuant to the expiration or
termination of this Lease, shall survive the expiration or termination of this
Lease and the Tenant shall pay amounts due to Landlord promptly upon demand.
Insofar as the annual determination and statement of Taxes is concerned,
Landlord agrees to make such additional accounting or adjustment as is necessary
following the expiration of the Lease Term, based upon the actual tax bills
received by Landlord after such date of Lease expiration inasmuch as such bills
are likely to be received after the accounting date and procedure set forth in
Section 6.

         Notwithstanding anything to the contrary contained in this Lease,
Tenant shall not be entitled to any payment or credit against Base Rent in the
event that the Consumer Price Index shall decrease from its January 1, 1989
level.

7.       HOLDING OVER.

         Should Tenant hold over after the termination of this Lease, by lapse
of time or otherwise, Tenant shall become a tenant from month to month only upon
each and all of the terms herein provided as may be applicable to such month to
month tenancy and any such holding over shall not constitute an extension of
this Lease, provided, however, during such holding over, Tenant shall pay
monthly Base Rent and Additional Rent (pursuant to Sections 5 and 6, or as
estimated by Landlord) at 150% of the rate payable for the month immediately
preceding said holding over and, in addition, Tenant shall pay to Landlord all
damages, consequential as well as direct, sustained by reason of Tenant's
holding over, unless Landlord has consented in writing to the hold-over. The
provisions of this Section do not exclude the Landlord's rights of re-entry or
any other right pursuant to this Lease.

constitute an eviction, whether such failure is caused by accident, breakage,
repairs, energy shortages or restrictions, strikes, lockouts or other labor
disturbances or labor disputes of any character, riots, civil disturbance or by
any other cause, similar or dissimilar, beyond the reasonable control of
Landlord. Landlord shall not be liable under any circumstances for loss of or
injury or other loss or damage, direct or indirect, regardless of type and
however occurring through, or in connection with or incidental to, failure to

limited to, word processing, photoreproduction, computer and telephone
equipment, are selected by Tenant for us in the Premises and such machinery or
equipment adversely affects the seasonal temperature otherwise maintained by the

thereof including the cost of installation and the cost of operation and
maintenance thereof, shall be paid by Tenant to Landlord upon demand by
Landlord, or (ii) charge Tenant for the additional costs for air conditioning

                                      19
<PAGE>
 
be borne by the other tenants or Landlord as excessive operating expenses) as

such special uses of water by Tenant, the Landlord, upon a notice of not less
than ten (10) days, may, in addition to any other remedy provided in this Lease,
discontinue furnishing that special service and no such discontinuance shall be
deemed an eviction or disturbance furnishing that special service and no such
discontinuance shall be deemed an eviction or disturbance furnishing that
special service and no such discontinuance shall be deemed an eviction or

Premises after the initial installation thereof at the commencement of the
Lease. Tenant covenants and agrees that at no time shall its use of electricity
current ever exceed the capacity of the feeders to the Building or the risers or
wiring installation. Tenant will not, without the prior written consent of
Landlord, use any apparatus or device in the Premises which will in any way
increase the amount of electricity or increase the amount of water which
Landlord determines to be reasonable for use of the Premises as general office

description which may arise out of, or be connected in any way with, said

<PAGE>
 
that any addition, hardware, non-trade fixture or improvement (whether temporary
or permanent), in or upon the Premises, be removed by Tenant at the termination
of this Lease, Landlord shall so advise Tenant prior to the installation of such
item in order that Tenant may determine whether such items should be installed
in light of Landlord's desire that such item be removed by Tenant at a later
date, provided Tenant has given Landlord, prior to the installation of such
item, reasonable written notice of the intended installation allowing Landlord
and its engineers and architects to examine such plans, and Tenant has complied
with all other provisions of this Lease which may affect such installation. The
Tenant shall remove the Tenant's furniture, machinery, safes, trade fixtures and
other items of personal property of ever kind and description from the Premises

days prior to notice to Tenant, and the Tenant shall promptly pay the cost
thereof. At any time or times, the Landlord, either voluntarily or pursuant to
governmental requirements, may, at the Landlord's own expense, make repairs,
alterations or improvements in or to the Building or any part thereof, including
the Premises, and, during operations, may close entrances, doors, corridors,

deemed abandoned, at the option of Landlord.

14.      ASSIGNMENT AND SUBLETTING.

         Tenant shall not assign this Lease, or any interest herein, and shall
not sublet the Premises or any part thereof, or any right or privilege
appurtenant thereto, or suffer any other person or entity to occupy or use the
Premises, or any portion thereof, without the prior written consent of 

                                      24
<PAGE>
 
Landlord first had and obtained. Landlord agrees not to unreasonably withhold
consent to any such assignment, occupancy or subletting provided: (i) at the
time thereof Tenant is not in default under this Lease; (ii) Landlord in its
sole discretion reasonably exercised, determines that the reputation, business,
proposed use of the Premises and financial responsibility of an by the proposed

the sum of amounts otherwise required to be paid pursuant to this Lease and all

one assignment, subletting, occupation or use by any person or entity other than
Tenant shall not be deemed to be a consent to any subsequent assignment,
subletting, occupation or use by another person or entity; and (vii) no such
assignment, subletting or occupation shall infer the ability to divide the
Premises into smaller suites or among more than one entity. Any such assignment,
subletting or occupancy without such consent shall be void and shall, at the
option of Landlord, constitute a default under this Lease. Neither this Lease
nor any interest herein shall be assignable as to the interest of Tenant by
operation of law without the written consent of Landlord, which consent may be
arbitrarily withheld. If Tenant shall at any time seek Landlord's consent to
assign this Lease or subject or have another person or entity occupy all of the
Premises as provided herein, then, within thirty (30) days following such notice
by Tenant to Landlord, which notice shall specify all particulars as Landlord
may request concerning the proposed sublease, assignment or occupancy including
but not limited to, names of proposed assignees of sublessees and term of the
proposed transaction, Landlord shall have the right to terminate this Lease as
to all of the Premises and recapture possession of the Premises, in which case
Tenant shall thereafter be released from all obligations under this Lease
accruing after such termination if such obligations relate to the remaining
portion of the Term following the date the Lease has been terminated and so long
as not in conflict with other provisions contained elsewhere in this Lease. In
the event that Tenant shall elect to attempt to assign or sublease all of its
Premises and shall choose to advertise, list with a real estate broker or
brokers, or otherwise show the Premises to prospective assignees or sub-lessees,
Tenant shall be required (i) to comply with Rules and Regulations in relation to
use of any likeness of the Building or Property, and (ii) to refrain from
publicly advertising a rental rate less than that then-quoted by the Landlord

from the outside of the Building or Premises without the prior written consent
of Landlord. The Tenant shall not display, inscribe, print, paint, maintain or
affix on any place in or about the Building or Property any sign, notice,
legend, direction, figure or advertisement.

17.      DAMAGE OR DESTRUCTION.

         In the event the Premises or the Building are damages by fire or other
casualty, Landlord may elect by notice to the Tenant within thirty (30) days
after the fire or casualty; (a) to terminate this Lease; or (b) to repair and

written notice to Tenant of such election to terminate, specify a date for the
termination of the Lease, which shall not be more than sixty (60) days after the
giving of such notice, and upon the date specified in such notice the Term shall

<PAGE>

Landlord shall be paid up to such date and any payments of rent made by Tenant
which were on account of any period subsequent to such date shall be returned to
Tenant. Unless Landlord shall serve a termination notice as provided for herein,
Landlord shall make the repairs and restorations under the conditions hereof
with all reasonable expedition. If the Landlord elects to so repair and restore
the Building or the Premises and does not substantially complete the work within
the one hundred eighty (180) day period or within such additional period to
which such period may be extended pursuant to the provisions of Section 27
hereof, either party may terminate this Lease as of the date of the fire or
casualty by notice to the other party not later than ten (10) days following the

not be canceled and terminated by reason of such damage as provided hereinabove,
then the base Rent and Additional Rent shall abate during the period beginning
with the date of such damage and ending with the date when the Premises are
again rendered tenantable. Such abatement shall be in an amount bearing the same
ratio to the total amount of Base Rent and Additional Rent for such period as
the untenantable portion of the Premises from time to time bears to the entire
Premises. Except as provided in this Section, there shall be no abatement of
rent and no liability of Landlord by reason of any injury to or interference
with Tenant's business or property arising from the making of any repairs,
alterations or improvements in or to any portion of the Building or the Premises
or in or to fixtures, appurtenances and equipment therein, which repairs,
alterations or improvements are necessitated by fire or other casualty.

on Tenant's furniture and furnishings or on any fixtures or equipment including
but not limited to, trade fixtures, removable by Tenant under the provisions of

thereto or to replace the same. Landlord shall not be required to repair any
damage thereto or to replace the same. Landlord shall not be required to repair
any injury or damage caused by fire or other cause or to make any repairs to or
replacements of improvements installed in the Premises by or for Tenant unless

pertinent details concerning replacement values. Tenant hereby agrees at
Tenant's election, to either: (i) insure the portion of tenant improvements and
other improvements made by Tenant as its cost within Tenant's premises to the
extent in excess of the Landlord's contribution as set forth in Exhibit C, and
provide Landlord a certificate of insurance evidencing such insurance coverage
which shall name Landlord as additional insured; or (ii) pay to Landlord as
Additional Rent or other rent from time to time, upon demand, the cost to
Landlord of insuring the portion of tenant improvements and other improvements
made by Tenant at its cost within Tenant's Premises to the extent in excess of
the Landlord's contribution as set forth in Exhibit C. Such charges shall b e
computed by Landlord on the basis of the appropriate prorated portion of
insurance premium allocable to Tenant at the actual rate from time to time being
charged to Landlord to insure improvements within the Building. Tenant's
election shall be in writing and shall be transmitted to Landlord prior to
completion of any such improvements. In the absence of such written election,
alternative (ii) shall apply.

purpose of examining or inspecting the same, to supply janitorial and cleaning
services and any other service to be provided by Landlord to Tenant hereunder,
to render emergency repair or other emergency service, to investigate unusual
noises or odors, to show the same to present or prospective purchasers, lenders,

tenants of the Building, and to make such alterations, repairs, improvements or
additions, whether structural or otherwise, to the Premises or to the Building
as Landlord may deem necessary or desirable. Landlord may enter by means of a
master key without liability to Tenant, except for any failure to exercise due
care for Tenant" property and without affecting this Lease. Landlord shall use
reasonable efforts on any such entry not to unreasonably interrupt or interfere
with Tenant's use and occupancy of the Premises.

19.      INSOLVENCY OR BANKRUPTCY.

         If, at any time during the Term or prior thereto, there shall be filed
by or against Tenant ii any court pursuant to any statute, either of the United
States or of any state, a petition in bankruptcy or insolvency or for
reorganization or for the appointment of a receiver or trustee of all or a
portion of Tenant's property, and within sixty (60) days thereof Tenant shall
fail to secure a discharge thereof, or if Tenant makes an assignment for the
benefit of creditors at the option of Landlord exercised within a reasonable
time after notice of the happening of any one or more of such events, this Lease
may be canceled and terminated, in which event neither Tenant nor any person
claiming through or under Tenant by virtue of any statute or of an order of any
court shall be entitled to possession or to remain in possession of the Premises
demised, but shall forthwith quit and surrender the Premises. In addition to the
other rights and remedies Landlord has by virtue of any other provisions herein
or elsewhere in this Lease contained or by virtue of any statute or rule of law,
Tenant specifically agrees that Landlord may retain any rent, security deposit
or other monies received by it from Tenant or others in behalf of Tenant to be
applied upon the obligations of Tenant hereunder as may be or become due and
unpaid in such manner as Landlord may deem appropriate.

20.      DEFAULT.

         If any of the following events of default shall occur, to wit:

               (i)   Tenant defaults in the payment of rent (whether Base Rent
         or Additional Rent or other rent) or any other sum required to be paid
         hereunder or any part thereof and such default shall continue for a
         period of ten (10) days after written notice thereof to Tenant, or

               (ii)  Tenant defaults in the prompt and full performance of any
         non-monetary covenant, agreement or condition of this Lease and such
         other default shall continue for a period of thirty (30) days after
         written notice thereof to Tenant (unless such default 

                                      29
<PAGE>
 
         involves a hazardous condition, in which event it shall be cured
         forthwith), excepting, however, any default which cannot be cured
         within such thirty (30) days period with which Tenant has commenced,
         and with due diligence is proceeding to cure. or

               (iii) The leasehold interest of Tenant be levied upon under
         execution or be attached by process of law or if Tenant abandons the
         Premises,

then, and in any such event, besides other rights or remedies it may have by law
or otherwise, Landlord shall have the immediate right of re-entry without
process of law and may remove all persons and property from the Premises; and
such property may be removed and stored in any other place, for the account of
and at the expense and at the risk of Tenant. Any such property of the Tenant
not claimed oar retaken from storage by Tenant within sixty (60) days after the
end of the Term, however, ended (or, in the event Tenant's right to possession
is terminated without a termination of this Lease, within sixty [60] days after
the date such right is terminated), shall be conclusively presumed to have been
conveyed by the Tenant to the Landlord under this Lease as a Bill of Sale
without further payment or credit by the Landlord to the Tenant. Tenant hereby
waives all claims for damages which may be caused by the re-entry of Landlord
and taking possession of the Premises or removing or storing the furniture and
property as herein provided, and shall save Landlord harmless from any loss,
costs or damages occasioned to Landlord thereby; and no such re-entry shall be
considered or construed to be a forcible entry or detainer, trespass or
eviction, or a relinquishment of Landlord's right to rent or other rights given
to Landlord hereunder or by operation of law.

         Should Landlord elect to re-enter, as herein provided, or take
possession pursuant to legal proceedings or pursuant to any notice provided for
by law, it may either terminate this Lease or it may, either terminate this
Lease or it may, but need not, from time to time, without terminating this
Lease, relet the Premises or any part thereof for such term or terms and at such
rentals and upon such other terms and conditions as Landlord in its sole
discretion may deem advisable, with the right to make alterations and repairs to
the Premises, the costs for which shall be paid for by Tenant, provided such
costs do not exceed the aggregate remaining financial obligations of Tenant
hereunder. The Landlord shall not be required to accept any tenant offered by
Tenant or otherwise observe any instructions given by the Tenant concerning such
reletting; provided, however, that if any substitute tenant tendered by Tenant
shall be financially responsible and shall, by all other normal and reasonable
standards, be at least as acceptable to Landlord as Tenant would be if Tenant
were not in default, then the approval of Landlord shall not be unreasonably
withheld.

         Landlord may elect to apply rentals received by it to any or all of the
following, in such order as Landlord may deem appropriate from time to time: (i)
to the payment of any indebtedness, other than rent, due hereunder from Tenant
to Landlord; (ii) to the payment of all costs, commissions and other expenses of
such reletting; (iii) to the payment of the cost of alterations and repairs to
the Premises; (iv) to the payment of rent due and unpaid hereunder; and the
residue, if any, shall be held by Landlord and applied in payment of future rent
as the same may become due and payable hereunder. If, at any time, the net rent
received from reletting after applications by Landlord of payments described in
the foregoing clauses (i) through (iv) be less 

                                      30
<PAGE>
 
than that agreed to be paid by Tenant hereunder, then Trustee shall pay such
deficiency to Landlord. Such deficiency shall be calculated by Landlord and paid
by Tenant to Landlord promptly on demand.

         In lieu of electing to terminate this Lease, to terminate possession,
or to receive and apply rentals as provided in the immediately preceding
paragraph, Landlord may elect to receive from Tenant, as and for Landlord's
liquidated damages for Tenant's default, an amount equal to the sum of the
present value of (i) the entire amount of Base Rent provided for in this Lease
for the remainder of the Term, plus all other amounts to become due and payable
to Landlord under any other provisions of this Lease for the remainder of the
Term, including, but not limited to, Additional Rent, other rent and other
amounts to become due from Tenant to Landlord, as may be, at Landlord's
election, projected by Landlord at the then current rates for such item(s) or
otherwise reasonably estimated by Landlord; plus (ii) all other amounts then due
and payable to Landlord under any other provisions of this Lease, including, but
not limited to, all then accrued and unpaid Base Rent, Additional rent, other
rent and other amounts then due from Tenant to Landlord such as, but not limited
to, payment for tenant improvements. For purposes of determining present value,
Landlord shall use a discount rate equal to one percent above the then-current
published or quoted prime or base rate charged by American National Bank and
Trust Company of Chicago on short term commercial loans to its customers.

         No such re-entry or taking possession of the Premises by Landlord shall
be construed as an election on its part to terminate this Lease unless a written
notice of such intention be given to Tenant pursuant to this Section 20 or
unless the termination thereof be decreed by a court of competent jurisdiction.
Notwithstanding any such reletting without termination, Landlord may at any time
thereafter elect to terminate this Lease for such previous breach.

         Nothing herein contained shall limit or prejudice the right of Landlord
to obtain as damages by reason of any such termination of this Lease or of
possession an amount equal to the maximum allowed by any statute or rule of law
in effect at the time when such termination takes place, whether or not such
amount be greater, equal to, or less than the amounts of damages which Landlord
may elect to receive as set forth above.

         The Tenant shall pay upon demand all the Landlord's costs, charges and
expenses, including the fees of counsel, agents and other retained by the
Landlord, incurred in enforcing the Tenant's obligations hereunder or incurred
by the Landlord in any litigation, negotiation or transaction in which the
Tenant causes the Landlord, without the Landlord's fault, to become involved or
concerned.

21.      RULES AND REGULATIONS.

         Tenant hereby agrees to obey the following rules and regulations, as
well as such rules and regulations as may be hereafter adopted by Landlord
pursuant to the provisions of Section 29, for the safety, care and cleanliness
of, and maintenance of good order in and on the Premises, the Building, the
Property and all contiguous property and improvements thereon. The violation by
Tenant of any such rules and regulations set forth in this Section 21 or as may

Tenant for the right of cancellation, and Tenant shall have no right to share in

25.      SUBORDINATION TO MORTGAGE AND DEEDS OF TRUST.

made subject and subordinate to the lien of any mortgage, mortgages or deeds of
trust now or hereafter existing 

                                      34
<PAGE>
 
against the Building, the Property or any part or parts thereof, and to all
renewals, modifications, consolidations, replacements and extensions thereof.
Although such subordination shall be self-operating, Tenant, or its successors
in interest, shall, upon Landlord's request, execute and deliver to Landlord any
and all instruments desired by Landlord subordinating in the manner requested by
Landlord this Lease to any such mortgage or deed of trust. Tenant shall execute
all such subordination instruments within ten (10) days after Tenant's receipt
of notice from Landlord (requiring the execution thereof.)

         Should any mortgage affecting the Building or the Property be
foreclosed: (i) the liability of the mortgagee, trustee or purchaser at such
foreclosure sale or the liability of a subsequent owner designated as Landlord
under this Lease shall exist only so long as such trustee, mortgagee, purchaser
or owner is the owner of the Building or Property and such liability shall not
continue or survive after further transfer of ownership; and (ii) Tenant shall
be deemed to have attorned, as tenant, under this Lease to purchaser at any
foreclosure sale thereunder subject to the condition that Tenant shall have the
right to remain in possession subject to the terms of this Lease, and this Lease
shall continue in force and effect as a direct lease between and binding upon
Tenant and such mortgagee. As used in this Section, "mortgagee" shall include
the successors and assigns of any such party, whether immediate or remote, the
purchaser of any mortgage, whether at foreclosure or otherwise, and the
successors, assigns and mortgagee of such purchaser, whether immediate or
remote. Tenant, to the extent not prohibited by law, waives the provisions of
any statute or rule of law, now or hereafter in effect, which may give or
purport to give Tenant any right or election to terminate or otherwise adversely
affect this Lease and the obligation of Tenant hereunder in the event any such
foreclosure proceeding is brought, prosecuted or completed.

         Notwithstanding the foregoing, if any mortgagee or trustee elects to
have this Lease and the interest of Tenant hereunder superior to any such
interest or right and evidences such election by notice given to Tenant, then
this Lease and the interest of Tenant hereunder shall be deemed superior to any
such instrument, whether this Lease was executed before or after such instrument
and in that event such mortgagee or trustee shall have the same rights with
respect to this Lease as if it had been executed and delivered prior to the
execution and delivery of such instrument and had been assigned to such
mortgagee or trustee. The provisions of this paragraph shall be self-operative
if such election shall be made and no further instrument shall be required;
provided, however, in confirmation thereof Tenant shall execute such further
assurances as may be required.

         So long as Tenant shall observe and perform its covenants and
agreements hereunder, Tenant shall, at all times during the Term herein granted,
peacefully and quietly have and enjoy possession of the Premises without any
encumbrance or hindrance by, from or through Landlord, its successors or
assigns, including any mortgagee.

         Landlord further reserves the right from time to time, without notice
to Tenant, to collaterally assign this Lease and the rents to become due to
Landlord hereunder as security for a loan or loans. Tenant Hereby consents to
all such assignments from time to time 

                                      35

(notwithstanding any lack of notice thereof) and upon notice to Tenant, Tenant
is hereby directed and agrees to comply with the terms of any such assignment.

26.      NON-WAIVER.

         The waiver by Landlord of any breach of any term, covenant or condition
therein contained shall not be deemed to be a waiver of the subsequent breach of
the same or any other term, covenant or condition herein contained. The
acceptance of rent or any other sums due to Landlord hereunder shall not be
construed to be a waiver of any breach by Tenant of any term, covenant or
condition of this Lease. It is understood and agreed that the remedies herein
given to Landlord shall be cumulative and the exercise of any one remedy by
Landlord shall not be to the exclusion of any other remedy.

27.      INABILITY TO PERFORM.

         This Lease and the obligation of Tenant to pay rent and other sums due
to Landlord hereunder and perform all of the other covenants and agreements
hereunder on the part of Tenant to be performed shall not be affected, impaired
or excused, nor shall Landlord at any time be deemed to be in default hereunder,
because Landlord is unable to fulfill any of its obligations under this Lease or
cannot supply or is delayed in supplying any service expressly or by implication
to be supplied or performed or is unable to make or is delayed in making any
Building improvements, repairs, additions, alterations or decorations or is
unable to supply or is delayed in supplying any equipment or fixtures if
Landlord is prevented or delayed from so doing by reason of any cause whatsoever
beyond the reasonable control of Landlord, including but not limited to strike
or labor disputes, Acts of God, riots and civil disturbances or energy shortages
or governmental preemption in connection with a national emergency or by reason
of any rule, order or regulation of any department or subdivision thereof or any
government agency or quasi-government agency or by reason of the conditions of
supply and demand which have been, are or may be affected by, war or other
emergency.

28.      SUBROGATION.

         The parties hereto agree to use good faith efforts to have any and all
fire, extended coverage and any and all material damage insurance which may be
carried endorsed with a subrogation clause to the effect that such insurance
shall not be invalidated nor shall the right of the insured to recovery
thereunder be adversely affected should the insured waive in writing prior to a
loss any or all right of recovery against any party for loss occurring to the
property described therein; and each party hereto hereby waives all claims for
recovery from the other party for any loss or damage (whether or not such loss
or damage is caused by negligence of the other party and notwithstanding any
provision or provisions contained in this Lease to the contrary) to any of its
property insured under valid and collectible insurance policies to the extent of
any recovery collected under such insurance, subject to the limitation that this
waiver shall apply only when it is not prohibited by the applicable policy of
insurance.

implied, herein contained in favor of Tenant, and in such event Tenant agrees to
look solely to the responsibility of the successor in interest of Landlord in
and to this Lease. If any security deposit has been made by Tenant, Landlord may
transfer or credit such security deposit to such successor in interest of
Landlord and thereupon Landlord shall be released from any further obligations
hereunder.

31.      RIGHT OF LANDLORD TO PERFORM.

         All covenants and agreements to be performed by Tenant under any of the
terms of this Lease shall be performed by Tenant at Tenant's sole cost and
expense and without any abatement of rent or setoff of any other amount due from

act on its part to be performed hereunder, and Tenant shall not have commence to

Tenant, make any such payment or perform any such other act on Tenant's part to
be made or performed as in this Lease provided. All sums so paid by Landlord and
all necessary incidental costs together with interest thereon at the rate set

payment by Landlord, shall be payable to Landlord promptly on demand. Tenant

non-payment thereof by Tenant as in the case of default by Tenant in the payment
of rent.

there are no uncured defaults in Landlord's performance and that nor more than
one (1) months' rent has been paid in advance. Further, such failure by Tenant

42.      ADDITIONAL RIDER PROVISIONS.

         a. Assignment and Subletting, Further Provisions. Anything to the
            ---------------------------------------------
contrary in Section 14 of the Lease notwithstanding, upon a prior written
notification to Landlord sufficiently detailed as to the circumstances and
financial aspects, but without requiring the prior consent of the Landlord,
Tenant may assign the Lease or sublet the Premises to any directly or 

                                      41
<PAGE>
 
indirectly wholly- or partially-owned subsidiary of The Dun & Bradstreet
Corporation or an affiliate thereof or Tenant or parent of Tenant or an
affiliate of Tenant or a successor corporation by a merger, consolidation or
sale of assets, subject to the condition that Tenant shall remain liable for the
faithful performance of all of the terms and covenants of the Lease, and further
subject to the condition that the financial responsibility of Tenant or Assignee
shall not have been materially diminished by merger, consolidation, sale of
assets, acquisition by a parent or other company or for any other reason and
that Assignee possesses a financial worth at least equivalent to Tenant's
financial worth at the date of execution hereof or can, in Landlord's
estimation, fulfill Tenant's obligations under this Lease. Tenant hereby agrees
to notify Landlord with the specifics thereof in advance of, or
contemporaneously with, any such merger, consolidation, sale of assets or
acquisition.

         Anything to the contrary in Section 14 of the Lease notwithstanding,
the spaces shall be so subleased in a manner so as not to divide the Premises
into small separate areas of less than one full wing, and the foregoing does not
and shall not be construed to be a waiver of Landlord's rights to approve any
alterations and additions as provided in Section 12 of this Lease.

         In the event Tenant shall at any time be required to seek Landlord's
consent to assign this Lease or sublet a portion or all of the Premises as
provided in Section 14 of this Lease and Landlord shall thereafter elect not to
terminate pursuant to said Section 14, then, in such event, Tenant shall pay to
Landlord, at the time and in the manner that it makes monthly payments of rent,
fifty percent (50%) of the excess (if any), after deducting Tenant's expenses
incurred in effecting the assignment or sublease, of the rent and all other
similar amounts received by Tenant from any such assignee or subtenant over the
sum of Base Rent (as periodically adjusted) and Additional Rent (as periodically
adjusted) then being paid by Tenant to Landlord for such space.

            ---------------
system for the Building which currently includes an after-hours key system for
entrance to the outer vestibule and, currently, a Honeywell magnetic card system
for access to the inner lobby atrium area. A Schlage central processing unit is
currently maintained by the Building management and controls card access into
the Building. If Tenant shall so elect, the Landlord shall make available to
Tenant magnetic card readers, wiring and related equipment for use at such of
its entrances as Tenant may choose, at a per-reader material, labor and an
overhead cost and fee of 21% to Tenant. The cost will vary depending upon floor,
distance of card reader from central connections within the Building and any
other necessary or desired related equipment. Currently, there is no charge for
use of conduit, wiring or other equipment of Landlord as may be located outside
the Building. A nominal monthly maintenance charge, on a per-card reader basis,
will be charged to Tenant if individual card readers are elected by Tenant for
the use of its employees in gaining entry into any of Tenant's Premises within
the Building. If requested, and at Tenant's costs, Landlord shall cooperate with
Tenant to cause a security key-pad or card reader to be installed in the
elevators and/or within the stairwells so as to bar access to the third floor
level by unauthorized persons.

                            Re:      Lease of Premises, Suite E-100, First Floor
                                       in Building B at
                                     Bannockburn Lake Office Plaza,
                                     To TSI International Software Ltd.

Gentlemen:

         In Accordance with the provisions of Paragraph 33 of that certain
Office Building Lease (the "Lease") dated January 26, 1994 by and between
American National Bank and Trust Company of Chicago, not individually but solely
as Trustee under Trust Agreement dated June 1, 1978 and known as Trust 42978
("Landlord") and TSI International Software Ltd. ("Tenant"), we hereby make the
following certifications to Transamerica Life Insurance and Annuity Company
("Transamerica")(and/or Landlord's other mortgagee):

         1.       The Lease is in full force and effect. The Term of the Lease
                  commences on May 1, 1994. The primary Least Term expires on
                  December 31, 1995. No necessary licenses and permits are
                  required. The use of the Premises is and will be lawful. The
                  Lease had not been modified.

         2.       There are not, to Tenant's knowledge, any uncured defaults on
                  the part of Landlord under the terms of the Lease.

         3.       Landlord has satisfied all conditions of an inducement nature
                  in the Lease.

         4.       Tenant has no charge, lien, claim or offset of any kind
                  against Landlord. Tenant will not withhold or reduce payments
                  on account of rent for any reason, except as may be specified
                  in the Lease.

                                      52
<PAGE>
 
         5.       If a security deposit has been paid to Landlord pursuant to
                  the Lease, Tenant agrees not to look to Transamerica, as
                  mortgagee, mortgagee in possession, or successor in title to
                  the Property for accountability on any security deposit
                  received by Landlord for the prompt and full performance by
                  Tenant under the Lease, unless said sum has actually been
                  received by Landlord for performance by Tenant under the Lease
                  and unless said sum has actually been received by
                  Transamerica.

         6.       Tenant understands that the Lease may have been collaterally
                  assigned to Transamerica as security for a loan to Landlord
                  and agrees that Tenant has not and will not prepay rent other
                  than the one month's rent next becoming due.

         7.       Tenant agrees that it will not terminate the Lease or its
                  tenancy on account of any default by Landlord unless Tenant
                  shall first have given a written notice to Transamerica
                  specifying such default and afforded a reasonable opportunity
                  to cure such default.

We understand and agree that the above certifications may be relied upon by the
above addressees and any prospective purchaser or encumbrancer of all or a
portion of the Property of which the Premises are a part.

                                            TENANT:

(Corporate Seal)                            TSI International Software Ltd.

                             ---------------------

1.   PARTIES.  This lease, dated, for reference purposes only, July 1, 1996, is
made by and between BOCA CORNERS L.P., LTD., a Georgia limited partnership
(herein called "Lessor") and TSI INTERNATIONAL SOFTWARE, LTD (herein called
"Lessee").

2.   PREMISES.  Lessor leases to Lessee and Lessee hereby leases for Lessor, for
the term, at the rental, and upon all of the conditions set forth herein, those
certain premises substantially as shown on the floor plan attached hereto as
Exhibit "A" (herein called the "Premises"), on Floor 2, in Suite 250, in the
office building (herein called the "Building") known as Lake Wyman Plaza,
located at 2424 North Federal Highway, Boca Raton, Florida 33431.

3.   TERM.

     3.1  TERM.  The term of this Lease shall be for sixty (60) months
commencing on December 1, 1996 ("Commencement Date") and ending on November 30,
2001 ("Termination Date") unless sooner terminated pursuant to any provision
hereof.

     3.2  DELAY IN POSSESSION.  Notwithstanding said commencement date, if for
any reason Lessor cannot deliver possession of the Premises to Lessee on said
date, Lessor shall not be subject to any liability therefor, nor shall such
failure affect the validity of this lease or the obligations of Lessee hereunder
or extend the term hereof, but in such case, Lessee shall not be obligated to
pay rent until possession of the Premises is tendered to Lessee.

     3.3  EARLY POSSESSION.  If Lessee occupies the Premises prior to said
commencement date, such occupancy shall be subject to all provisions hereof,
such occupancy shall not advance the termination date, and Lessee shall pay rent
for such period at the initial monthly rates set forth below.

4.   RENT.

     4.1  BASIC MONTHLY RENT.  Lessee shall pay to Lessor, as initial Basic
Monthly Rent for the Premises, monthly payments of $9,642.50 each, plus
applicable sales tax as provided in paragraph 4.3(g), in advance, on the first
day of each month of the term hereof, subject to adjustments as provided in
paragraphs 4.2 and 4.3.  Lessee shall pay to Lessor upon execution hereof the
sum of $15,849.10 as rent for the first month of the term hereof.  Rent for any
period during the term hereof which is less than one month shall be a pro rata
portion of the monthly payment.  Rent shall be payable in lawful money of the
United States to Lessor at the address stated herein or at such other persons or
at such other places as Lessor may designate in writing.

     4.2  ANNUAL ADJUSTMENT.  The Base Monthly shall be a minimum rental for the
initial term of this lease.  Subsequent to the commencement of the second Lease
Year and subsequent to the commencement of each Lease Year thereafter, the Base
Monthly Rent shall be increased by an amount equal to four percent (4%) per
annum.  Accordingly, the Base Monthly Rent due for the second Lease Year and for
each Lease Year thereafter shall equal to one hundred four percent (104%) of the
Base Monthly Rent prevailing hereunder for the Lease Year immediately preceding
the increase.  Each "Lease Year" shall consist of each period of twelve (12)
month subsequent to the Commencement Date.

     4.3  BUILDING EXPENSE ADJUSTMENTS.

          (a) Lessee agrees to pay as additional rent for the Lessee's
proportionate share of all Building Expenses as hereinafter defined, incurred by

thereto.  Such additional rent shall be payable in equal monthly installments

<PAGE>
 
so as to escrow Lessee's proportionate share during each calendar year during
the term of this Lease. Lessee's proportionate shall be 5.1%.

          (b) Prior to the commencement of the Lease term and of each calendar
year thereafter, Lessor shall use best efforts to provide Lessee a written
estimate of Building Expenses and Lessee's proportionate share thereof for the
ensuing year or portion thereof.  If, during the course of any year, it appears
that Lessor's estimate of Building Expenses was insufficient, Lessor may revise
its written estimate.  Lessee shall pay the then current estimated amount to
Lessor as additional rent, in equal monthly installments, in advance.  Within
one hundred twenty (120) days after the end of each calendar year, Lessor shall
furnish to Lessee a statement showing in reasonable detail the actual Building
Expenses incurred by Lessor during such period, and the parties, shall within
thirty (30) days thereafter make any payment or allowance necessary to adjust
Lessee's estimated payments to Lessee's actual proportionate share required by
such annual payment.  Any amount due to Lessee shall be credited against
installments next coming due under this paragraph 4.

          (c) The term "Building Expenses" as used herein shall include all
costs of operation and maintenance of the Building and appurtenances thereto, as
determined by generally accepted accounting practices consistently applied, and
shall include the following costs by way of illustration but not limitation:

compensation, uniforms and related expenses for employees; (3) the cost of all

depreciation of hand tools and other movable equipment used in the repair,
maintenance, or operation of the Building; (8) the cost of all charges for
window and other cleaning and janitorial and security services; (9) amounts

Building or any portions thereof made by the Lessor at its expense; (11)
alterations and improvements to the Building made by reason of laws and
requirement of any public authorities or the requirements of insurance bodies;
(12) management fees; (13) the cost of any capital improvements to the building
or of any machinery or equipment installed in the Building which is made or
becomes operational, as the case may be, and which has the effect of reducing
the expenses which otherwise would be included in the Building Expenses, to the
extent of the lessor of: (i) such cost, amortized over the useful life of the
improvements, machinery or equipment (as reasonably estimated by Lessor), or
(ii) the amount of each reduction in the Building Expenses; (14) reasonable
legal, accounting and other professional fees incurred in connection with the
operation, maintenance, and management of the Building; (15) refurbishing,
repainting, recarpeting or redecorating any portion if the Building; (16) taxes,
as hereinafter defined; and (17) all other charges allocable to the repair,
operation, and maintenance of the Building in accordance with generally accepted
accounting principles.

          The term "Taxes" as referred to in Subparagraph 4.3(d)(p) above, shall
mean the aggregate amount for which the Building, and all land or real property
owned by Lessor underlying the Building or adjacent thereto and used in
connection with the operation of the Building are assessed by the County or any
city or municipal or other governmental body having jurisdiction for the purpose
of imposition of real estate taxes, and any expenses incurred by Lessor in
contesting such taxes or 

                                 Page 2 of 31
<PAGE>
 
assessments of the assessed value of the Building. Any special or other
assessment or levy which is imposed upon the Building shall be added to the
amount so determined and shall be deemed to be included within the term "Taxes"
for the purpose hereof. If at any time during this Lease, the methods of
taxation prevailing on the date hereof shall be altered, such additional or
substitute tax, assessment, levy, imposition, or charge, shall be deemed to be
included within the term "Taxes" for the purpose hereof.

          Notwithstanding the above, the following are excluded for the
definition of Building Expenses: depreciation (except as provided above);
interest on and amortization of debts; improvements made for new lessees' of the
Building; refinancing costs; the cost of any work or services performed for nay
lessee of the Building, to the extent that such work or service is separately
reimbursed; the cost of any repair or replacement (other than those described
above) which would be required to be capitalized under generally accepted
accounting principles, unless such cost may be, under said principles, amortized
over a period of not more than ten (10) years, in which event a proportionate
part of such costs may be included each year in Building Expenses over the
useful life (as reasonably estimated by Lessor) of such repair and replacement.

          Notwithstanding any provision in this Lease to the contrary, the
Building Expenses which have a direct relationship to occupancy, shall be
determined as though the Building were at an occupancy rate of one hundred
percent (100%).

          (d) Annual and other determinations of Building Expenses hereunder
shall be made reasonably and in good faith by Lessor. In the event of any
dispute as to the amount thereof. Lessee shall have the right after reasonable
notice and at reasonable times to inspect Lessor's accounting in any calendar
year. Such inspection will be conducted where Lessor maintains Building Expense
records Lessee shall not have the right to inspect at any time Lessee is in
default of any of the terms of the Lease. Inspection rights shall only pertain
to the Lessee and not any subtenants or assignees. If, after such inspection,
Lessee still disputes the Lessor's determination, certification as to the proper
amount shall be made by Lessor's independent certified public accountant, and
such certification shall be final and conclusive. Lessee agrees to pay the cost
of such certification unless it is determined that Lessor's original
determination was in error to Lessee's disadvantage by more than five percent
(5%). Lessee agrees that the payment of any disputed sum and, if applicable, the
deposit of the estimated cost of certification, shall be conditions precedent to
the initiation of the foregoing procedure.

          (e) The Basic Monthly Rent, and other amounts required to be paid by
Lessee hereunder, are sometimes collectively referred to as, and shall
constitute, "rent".

          (f) In addition to Base Monthly Rent, as adjusted and with all
additions thereto, Lessee shall pay all sales, use occupancy or other taxes
levied by the State of Florida, or any other governmental jurisdiction having
authority for the privilege of leasing or occupying the premises.

5.   SECURITY DEPOSIT.  Lessee shall deposit with Lessor upon execution hereof
$16,683.23 as security for Lessee's faithful performance of Lessee's obligations
hereunder.  If Lessee fails to pay rent or other charges hereunder, or otherwise
defaults with respect to any provision of this Lease, Lessor may use, apply or
retain all or any portion of said deposit for the payment of any rent or other
charge in default or for the payment of the any other sum to which Lessor may
become obligated by reason of Lessee's default, or to compensate Lessor for any
loss or damage which Lessor may suffer thereby.  If Lessor so uses or applies
all or any portion of said deposit, Lessee shall within ten (10) days after
written demand therefor deposit cash with Lessor in an amount sufficient to
restore the said deposit to the full amount hereinabove stated and Lessee's
failure to do so shall be in a material breach of this Lease.  Lessor shall not
be required to keep said deposit separate from its general accounts.  If Lessee
performs all of Lessee's obligations hereunder, said deposit, or so much thereof
as has not theretofore been applied by Lessor, shall be returned, without
payment of interest or other increment for its use, to Lessee (or, at Lessor's
option, to the last assignee, if any, of Lessee's interest hereunder) within
thirty (30) days of the 

                                 Page 3 of 31

trust relationship is created herein between Lessor and Lessee with respect to
said Security Deposit.

business purposes.  Only Lessee may conduct business from the Premises subject
to the requirements of paragraph 12 hereof.

promptly with all applicable statues, ordinances, rules regulations, orders,
covenants, and restrictions, and requirements in effect during the term of any
part of the term hereof, regulating the use by Lessee of the Premises.  Lessee
shall not use or permit the uses of the Premises in any manner that will tend to
create waste or a nuisance or to disturb other tenants in the Building.

     6.2  CONDITION OF PREMISES.  Lessee hereby accepts the Premises in their
condition existing as of the lease commencement date or the date that Lessee
takes possession of the Premises, whichever is earlier, subject to Exhibit "C"
attached hereto and subject to all applicable zoning, municipal, county and
state laws, ordinances and regulations governing and regulating the use of the

representation or warranty as to the present or future suitability of the
Premises for the conduct of Lessee's business.

and every part thereof, including, without limiting the generality of the
foregoing, all of Lessee's personal property, fixtures, signs, interior walls
and interior surfaces of exterior walls, ceilings, windows, doors, plate glass
and skylights located within the Premises.  Lessee expressly waives the benefit
of any statute now or hereinafter in effect which would otherwise afford Lessee
the right to make repairs at Lessor's expense or to terminate this lease because
of Lessor's failure to keep the premises in good order, condition and repair.

          (b) If Lessee fails to perform Lessee's obligations under this
paragraph 7.2 or under any other paragraph under this Lease.  Lessor may at
Lessor's option enter upon the Premises after ten (10) days prior written notice
to Lessee (except in the case of emergency, in which case no notice shall be
required), perform such obligations on Lessee's behalf and put the premises in

to the exterior of the Premises nor the exterior of the Building without
Lessor's prior written consent.  As used in this paragraph 7.3 the term "Utility

Lessor may require Lessee to provide Lessor, at Lessee's sole cost and expense,
a lien and completion bond in an amount equal to one and one-half times the
estimated cost of such improvements, to insure Lessor against any liability for
mechanics or materialmen's liens and to insure completion of the work.  Should
Lessee make any alterations, improvements, additions, or Utility Installations
without the prior approval of Lessor, Lessor may require that Lessee remove any
or all of the same.

          (b) Any alterations, improvements, additions or Utility Installation
in, or about the Premises that Lessee shall desire to make and which requires

proposed detailed plans.  If Lessor shall give its consent, the consent shall be
deemed conditioned upon Lessee acquiring a permit to do so from appropriate

commencement of the work and the compliance by Lessee of all condition of said
permit in a prompt and expeditious manner.

          (c) Lessee shall pay, when due, all claims for labor or materials

than ten (10) days' notice prior to the commencement of any work in the
Premises, and Lessor shall have the right to record a Memorandum of Lease in the
public records as provided by law.  If Lessee shall, in good faith, contest the
validity of any such lien, claim or demand, then Lessee shall, at its sole
expense defend itself and Lessor against the same and shall pay and satisfy any
such adverse judgment that may be rendered thereon before the enforcement
thereof against the Lessor or the Premises, upon the condition that if Lessor
shall require, Lessee shall furnish to Lessor a security bond satisfactory to
Lessor in an amount equal to such contested lien claim or demand indemnifying
Lessor against liability for the same and holding the Premises free from the
effect of such lien or claim.  In addition, Lessor may require Lessee to pay
Lessor's attorneys fees and cost in participating in such action if Lessor shall

improvement bond or bonds, levy or tax (other than inheritance, personal income
or estate taxes) imposed on the Premises by any authority having the direct
power to tax, including any city, state or federal government, or any school,
agricultural, sanitary, fire, street, drainage or other improvement district
thereof, as against any legal equitable interest of Lessor in the Premises or in
the real property of which the Premises are a part, as against Lessor's right to
rent or other income therefrom, and as against Lessor's business of leasing the
Premises.  The term "real property tax" shall also include any tax, fee, levy,
assessment or charge (i) in substitution of, partially or totally, any tax, fee,
levy, assessment or charge hereinabove included within the definition of "real
property tax" or (ii) the nature of which was hereinbefore included within the
definition of "real property tax."

     10.4  PERSONAL PROPERTY TAXES.

          (a) Lessee shall pay prior to delinquency all taxes assessed against
and levied upon trade fixtures, furnishings, equipment and all other personal
property of Lessee contained in the Premises or elsewhere.  When possible,
Lessee shall cause said trade fixtures, furnishings, equipment and all other
personal property to be assessed and billed separately from the real property of
Lessor.

          (b) If any of Lessee's said personal property shall be assessed with
Lessor's real property, Lessee shall pay Lessor the taxes attributable to Lessee
within 10 days after receipt of a written statement setting forth the taxes
applicable to Lessee's property.

11.  UTILITIES.  Lessee shall pay for all water, gas, heat, light, power,
telephone and other utilities and services supplied to the Premises, together
with any taxes thereon.  If any such services are not separately metered to
Lessee, Lessee shall pay a reasonable proportion to be determined by Lessor of
all charges jointly metered with other premises.  All such charges not
separately metered shall be a Building Expense.

12.  ASSIGNMENT AND SUBLETTING.

     12.1  LESSORS CONSENT REQUIRED.  Lessee shall not voluntarily or
involuntarily assign, sublet, mortgage or otherwise encumber all or any portion
of its interest in this Lease or in the Premises without obtaining the prior
written consent of Lessor, which consent shall not be unreasonably withheld, and
any such attempted assignment, subletting, mortgage or other encumbrance with
such consent shall be null

                                 Page 9 of 31
<PAGE>
 
and void and of no effect. It shall not be unreasonable for Lessor to withhold
its consent in order to exercise its rights set forth in paragraph 12.4.

     12.2  NO RELEASE OF LESSEE.  No permitted assignment, subletting, mortgage
or other encumbrance of Lessee's interest in this Lease shall relieve Lessee of
its obligation to pay the rent and to perform all of the other obligations to be
performed by Lessee hereunder.  The acceptance of rent by Lessor from any other
person shall not be deemed to be a waiver by Lessor of any provision of this
Lease or be a consent to any subletting, assignment, mortgage or other
encumbrance.  Consent to one sublease, assignment, mortgage other encumbrance
shall not be deemed to constitute consent to any subsequent attempted
subletting, assignment, mortgage or other encumbrance.

     12.3  SUBMISSION TO LESSOR.  If Lessee desires at any time to assign this
Lease or to sublet the Premises or any portion thereof, it shall first notify
Lessor of its desire to do so and shall submit it in writing to Lessor (i) the
name of the proposed subtenant or assignee; (ii) the nature of the proposed
subtenant's or assignees business to be carried on in the Premises; (iii) the
terms and provisions of the proposed sublease or assignment; and (iv) such
financial information as Lessor may reasonably request concerning the proposed
subtenant or assignee.

     21.4  LESSOR'S ELECTION TO RECAPTURE.  At any time within thirty (30) days
after Lessor's receipt of the information specified in paragraph 12.3 above,
Lessor may by written notice to Lessee elect (i) to sublease the Premises or the
portion thereof so proposed to be subleased by Lessee, or to take an assignment
of Lessee's leasehold estate hereunder, or such part thereof as shall be
specified in the said notice, on the same terms stated in this Lease and in turn
sublease or assign to the proposed subtenant of assignee on the same terms as
those offered by Lessee to the proposed subtenant or assignee, as the case may
be; or (ii) to terminate this Lease as to the portion (including all) of the
Premises so proposed to be subleased or assigned, with a proportionate abatement
in the rent payable hereunder; provided, however, that if the proposed sublease
will cover less than one-half of the area of the Premises covered by this Lease,
will have a term (including all options to renew or extend the same) of less
than two years, and will terminate more than two years prior to the expiration
date of this Lease, then Lessor shall not be entitled to exercise option (ii)
above, but may exercise option (i).  If Lessor does not exercise any option set
forth in this paragraph 12.4 within the said thirty (30) day period, Lessee may
thereafter within ninety (90) days after the expiration of said thirty (30) day
period enter into a valid assignment or sublease of the Premises or portion
thereof, upon the terms and conditions set forth in the information furnished by
Lessee to Lessor pursuant to paragraph 12.3 above, subject, however, in each
instance, to Lessor's consent, which shall not unreasonably be withheld as set
forth in paragraph 12.1 above.

     12.5  OTHER PROVISIONS.  The voluntary or other surrender of this Lease by
Lessee or a mutual cancellation hereof shall not work a merger, and shall at the
option of Lessor, terminate all or any existing subleases or subtenancies or
shall operate as an assignment to Lessor of such subleases or subtenancies.  If
Lessee is a corporation, or is an unincorporated association or partnership, the
transfer, assignment or hypothecation of any stock or interest in such
corporation, association or partnership in the aggregate in excess of fifty
percent (50%) shall be deemed an assignment within the meaning of this Paragraph
12.  Lessee agrees to reimburse Lessor for Lessor's reasonable costs and
attorneys' fees incurred in conjunction with the processing and documentation of
any requested assignment, subletting, transfer, change of ownership or
hypothecation of this Lease or Lessee's interest in and to the Premises.

13.  DEFAULT.  In the event that Lessee defaults in the payment of any rent due
hereunder or in any other obligations under this Lease, and fails to cure such
default within (5) days after notice thereof, Lessor may accelerate all rent due
hereunder and may also, at its option, proceed with any and all of its remedies
provided by this Lease, including, but not limited to, the removal of the tenant
from the Premises.  Lessee shall vacate the Premises within fifteen (15) days of
notice from Lessor.  Lessor may take possession of the Premises on said date and
recover all rents and damages accrued or accruing hereunder.  If on account of
any breach or default by Lessee in its obligations under this lease, it shall

                                 Page 10 of 31
<PAGE>
 
become necessary for Lessor to employ legal services to enforce or defend
Lessor's rights or remedies hereunder, Lessee agrees to pay any reasonable
attorneys' fees thus incurred by Lessor.  If Lessee files a petition in
bankruptcy or be adjudicated a bankrupt, or makes an assignment for the benefit
of creditors or takes advantage of any insolvency act, Lessor may, at its option
at any time thereafter, terminate this Lease upon giving Lessee fifteen (15)
days notice of Lessor's intention to do so, and this Lease shall then expire and
end on that date fixed in such notice as if said date were the date originally
fixed in this Lease for the expiration hereof.  If the Premises shall be vacated
or abandoned, or in the event of a default by Lessee, for any cause whatsoever,
Lessee shall, nevertheless, remain and continue liable to Lessor in a sum equal
to all fixed and additional rent herein reserved for the balance of the term
herein originally granted; and Lessor may re-enter the Premises using such
reasonable force for that purpose as may be necessary without being liable to
any prosecution for said re-entry or the use of such force, and Lessor may
repair or alter the Premises in such manner as Lessor may deem necessary or
advisable, or relet the Premises or any or all parts thereof for the whole or
any part of the remainder of the original term hereof or for a longer period, in
Lessor's name, or as the agent of Lessee, and out of any rent so collected or
received.  Lessor shall first pay to itself the expense and cost of retaking,
repossessing, repairing, or altering the Premises (including court costs and
legal fees) and the expense of removing all persons and property therefrom, and,
second, pay to itself any cost or expense sustained in securing any new tenant
or tenants, and, third, pay to itself any balance remaining on account of the
liability of Lessee to Lessor for the sum equal to the rents reserved herein and
then unpaid by Lessee for the remainder of the term originally herein demised.
Any entry or re-entry by Lessor, whether had or taken under summary proceedings
or otherwise shall not absolve or discharge Lessee from liability hereunder.

     Should any rent so collected by Lessor after the payments aforesaid be
insufficient to pay to Lessor a sum equal to all fixed and additional rent
herein reserved, the balance or deficiency shall be paid by Lessee and Lessee
shall be and remain liable for any such deficiency.

     Suit or suits for the recovery of any such deficiency or damages, or for a
sum equal to any installment or installments of rent or additional rent payable
hereunder, may be brought by Lessor from time to time at Lessor's election.

     In the event of a breach or a threatened breach by Lessee of any of the
terms, covenants or conditions hereof, Lessor shall have the right of injunction
to restrain the same and the right to invoke any removal allowed by law or in
equity, as if specific remedies, indemnify or reimbursement where not herein
provided for.

     The rights and remedies given to Lessor in this Lease are distinct,
separate and cumulative remedies and no one of them, whether or not exercised by
Lessor, shall be deemed to be in exclusion of any of the others herein by law or
equity provided.

     The receipt of rent by Lessor with knowledge of any breach of this Lease by
Lessee or of any default on the part of Lessee in the observance or performance
of any of the terms, covenants, or conditions of this Lease, shall not be deemed
to be a waiver of any provision of this Lease.

     No receipt of monies by Lessor from Lessee shall reinstate, continue or
extend the term hereof, or affect any notice theretofore given to Lessee, or
operate as a waiver of the right of Lessor to enforce the payment of fixed or
additional rent or other charges then due or thereafter falling due or operate
as a waiver of the right of Lessor to recover possession of the premises by
proper suit, action, proceedings or remedy; it being agreed that, after the
service of notice of default, and the expiration of the time therein specified,
if the default has not been cured in the meantime, or after the commencement of
suit, action or summary proceedings or of any other remedy, or after a final
order, warrant or judgment for the possession of the Premises, Lessor may
demand, receive, and collect any monies then due, or thereafter becoming due,
without in any manner affecting such notice, proceeding, suit, action, order,
warrant or judgment and any and all such monies so collected shall be deemed to
be payments on account for the

                                 Page 11 of 31
<PAGE>
 
use and occupation of the Premises, or at the election of Lessor, on account of
Lessee's liability hereunder. Acceptance of the keys to the premises, or any
similar act, by Lessor, or any agent or employee, during the term hereof, shall
not be deemed to be an acceptance of a surrender of the Premises unless Lessor
shall consent thereto in writing.

     13.3  DEFAULT BY LESSOR.  Lessor shall not be in default unless Lessor
fails to perform obligations required of Lessor within a reasonable time, but in
no event later than thirty (30) days after written notice by Lessee to Lessor
and to the holder of any first mortgage or deed of trust covering the Premises
whose name and address shall have theretofore been furnished to Lessee in
writing, specifying wherein Lessor has failed to perform such obligation,
provided, however, that if the nature of Lessor's obligation is such that more
than thirty (30) days are required for performance then Lessor shall not be in
default if Lessor commences performance within such 30-day period and thereafter
diligently prosecutes the same to completion.

     13.4  LATE CHARGES.  Lessee hereby acknowledges that late payment by Lessee
to Lessor of rent and other sums due hereunder will cause Lessor to incur costs
not contemplated by this Lease, the exact amount of which will be extremely
difficult to ascertain.  Such costs include, but are not limited to, processing
and accounting charges, and late charges which may be imposed on Lessor by the
terms of any mortgage or trust deed covering the Premises.  Accordingly, if any
installment of rent or any other sum due from Lessee shall not be received by
Lessor or Lessor's designee within five (5) days after such amount shall be due,
then, without any requirement for notice to Lessee, Lessee shall pay to Lessor a
late charge equal to 6% of such overdue amount.  The parties hereby agree that
such late charge represents a fair and reasonable estimate of the costs Lessor
will incur by reason of late payment by Lessee.  Acceptance of such late charge
by Lessor shall in no event constitute a waiver of Lessee's default with respect
to such overdue amount, nor prevent Lessor from exercising any of the other
rights and remedies granted hereunder.  In the event that a late charge is
payable hereunder, whether or not collected, for three (3) consecutive
installments of rent, then rent shall automatically become due and payable
quarterly in advance, rather than monthly, notwithstanding paragraph 4 or any
other provision of this Lease to the contrary.

14.  CONDEMNATION.  If the Premises or any portion thereof are taken under the
power of eminent domain, or sold under the threat of the exercise of said power
(all of which are herein called "condemnation"), this lease shall terminate as
to the part so taken as of the date the condemning authority takes title or
possession, whichever first occurs.  If more than 10% of the floor area of the
Premises is taken by condemnation, Lessee may, at Lessee's option, to be
exercised in writing only within ten (10) days after Lessor shall have given
Lessee written notice of such taking (or in the absence of such notice, within
ten (10) days after the condemning authority shall have taken possession)
terminate this Lease as of the date the condemning authority takes such
possession.  If Lessee does not terminate this Lease in accordance with the
foregoing, this Lease shall remain in full force and effect as to the portion of
the Premises remaining, except that the rent shall be reduced in the proportion
that the floor area taken bears to the total floor area of the Premises.  Any
award for the taking of all or any part of the Premises under the power of
eminent domain or any payment made under threat of the exercise of such power
shall be the property of Lessor, whether such award shall be made as
compensation for diminution in value of the leasehold or for the taking of the
fee, or as severance damages; provided, however, that Lessee shall be entitled
to any award for loss of or damage to Lessee's trade fixtures and removable
personal property.  In the event that this Lease is not terminated by reason of
such condemnation, Lessor shall to the extent of severance damages received by
Lessor in connection with such condemnation, repair any damage to the Premises
caused by such condemnation except to the extent that Lessee has been reimbursed
therefor by the condemning authority.  Lessee shall pay any amount in excess of
such severance damages required to complete such repair.

15.  ESTOPPEL CERTIFICATE.

     (a) Lessee shall at any time upon not less than ten (10) days prior written
notice from Lessor execute, acknowledge and deliver to Lessor a statement in
writing (i) certifying that this Lease is unmodified and in full force and
effect (or, if modified, stating the nature of such modification and certifying
that this Lease, as so modified, is in full force and effect) and the date to
which the rent and other charges are paid in advance, if any, and (ii)
acknowledging that there are not, to Lessee's knowledge, any uncured defaults on
the part of Lessor hereunder, or specifying such defaults if any are claimed.
Any such statement may be conclusively relied upon by any prospective purchaser
or encumbrancer of the Premises.

     (b) At Lessor's option, Lessee's failure to deliver such statement within
such time shall be a material breach of this Lease or shall be conclusive upon
Lessee (i) that this Lease is in full force and effect without modification
except as may be represented by Lessor, (ii) that there are no uncured defaults
in Lessor's performance, and (iii) that not more than one month's rent has been
paid in advance or such failure may be considered by Lessor as a default by
Lessee under this Lease.

     (c) If Lessor desires to finance, refinance, or sell the Premises, or any
part thereof, Lessee hereby agrees to deliver to any lender or purchaser
designated by Lessor such financial statement of Lessee as may be reasonably
required by such lender or purchaser.  Such statements shall include the past
three years' financial statements of Lessee.  All such financial statements
shall be received by Lessor and such lender or purchaser in confidence and shall
be used only for the purposes herein set forth.

16.  LESSOR'S LIABILITY.  The term "Lessor" as used herein shall mean only the
owner or owners at the time in question of the fee title or a Lessee's interest
in a ground lease of the Premises, and except as expressly provided in paragraph
15, in the event of any transfer of such title or interest.  Lessor herein names
(and in case of any subsequent transfers than the grantor) shall be relieved
from and after the date of such transfer of all liability as respects to
Lessor's obligations thereafter to be performed, provided that any funds in the
hands of Lessor or the then grantor at the time of such transfer, in which
Lessee has an interest, shall be delivered to the grantee.  The obligation
contained in this Lease to be performed by Lessor shall, subject to the
aforesaid, be binding on Lessor's successor and assigns, only during their
respective periods of ownership.

17.  SEVERABILITY.  The invalidity of any provision of this Lease as determined
by a court of competent jurisdiction, shall in no way effect the validity of any
other provision hereof.

18.  INTEREST ON PAST-DUE OBLIGATIONS.  Except as expressly herein provided, any
amount due to Lessor not paid when due shall bear interest at the maximum rate
then allowable by law from the date due.  Payment of such interest shall not
excuse or cure any default by Lessee under this Lease, provided, however, that
interest shall not be payable on late charges incurred by Lessee nor on any
amounts upon which late charges are paid by Lessee.

19.  TIME OF ESSENCE.  Time is of the essence.

20.  ADDITIONAL RENT.  Any monetary obligations of Lessee to Lessor under the
terms of this Lease shall be deemed to be rent.

21.  INCORPORATION OF PRIOR AGREEMENTS; AMENDMENTS.  This Lease contains all
agreements of the parties with respect to any matter mentioned herein.  No prior
agreement or understanding pertaining to such matter shall be effective.  This
Lease shall be modified in writing only, signed by the parties in interest at
the time of the modification.  Except as otherwise stated in this Lease, Lessee
hereby acknowledges that neither Lessor nor any employees or agents of any of
Lessor has made any oral or written warranties or representations to Lessee
relative to the condition or use by Lessee of said Premises

                                 Page 13 of 31
<PAGE>
 
and Lessee acknowledges that Lessee assumes all responsibility regarding the
Occupational Safety Health Act (OSHA), the legal use and adaptability of the
Premises and the compliance thereof with all applicable laws and regulations in
effect during the term of this Lease except as otherwise specifically stated in
this Lease.

22.  NOTICES.  Any notice required or permitted to be given hereunder shall be
in writing and may be given by personal delivery or by certified mail, and if
given personally or by mail shall be deemed sufficiently given if addressed to
Lessee or to Lessor at the address noted below the signature of the respective
parties as the case may be.  Either party may by notice to the other specify a
different address for notice purposes accept that upon Lessee's taking
possession of the Premises the Premises shall constitute Lessee's address for
notice purposes.  A copy of all notices required or permitted to be given to
Lessor hereunder shall be concurrently transmitted to such party or parties at
such addresses as Lessor may from time to time hereafter designate by notice to
Lessee.

23.  WAIVERS.  No waiver by Lessor of any provision hereof shall be deemed a
waiver of any provision hereof or of any subsequent breach by Lessee of the same
or any other provision.  Lessor's consent to, or approval of any act, shall not
be deemed to render unnecessary the obtaining of Lessor's consent to or approval
of any subsequent act by Lessee.  The acceptance of rent hereunder by Lessor
shall not be a waiver of any preceding breach by Lessee of any provisions
hereof, other than the failure of Lessee to pay the particular rent so accepted,
regardless of Lessor's acknowledge of such preceding breach at the time of
acceptance of such rent.

24.  RECORDING.  Lessee shall, upon request of Lessor, execute, acknowledge and
deliver to Lessor a "short form" memorandum of this Lease for recording
purposes.  Unless requested by Lessor, neither this Lease nor a "short form"
hereof shall be recorded.  If Lease or "short form" is recorded, other than, by
the request of Lessor, such action would be considered a material default of the
Lease.

25.  HOLDING OVER.  If Lessee, with Lessor's consent, remains in possession of
the Premises or any part thereof after the expiration of the term hereof, such
occupancy shall be a tenancy at sufferance.  Except as set forth in this
paragraph to the contrary, all the provisions of this Lease pertaining to the
obligations of Lessee shall apply to the Tenant during its occupancy at
sufferance.  All options and rights of first refusal, if any, granted to Lessee
under the terms of this Lease shall be deemed terminated and be of no further
effect during said tenancy at sufferance, Base Monthly Rent during the tenancy
at sufferance shall be one and one-half times the Base Monthly Rent for the last
month during which the Lease was in effect.  The Tenant shall vacate the
Premises upon written demand by Lessor.

26.  CUMULATIVE REMEDIES.  No remedy or election hereunder shall be deemed
exclusive but shall, wherever possible, be cumulative with all other remedies at
law or in equity.

27.  COVENANTS AND CONDITIONS.  Each provision of this Lease performable by
Lessee shall be deemed both a covenant and a condition.

28.  BINDING EFFECT; CHOICE OF LAW.  Subject to any provisions hereof
restricting assignment or subletting by Lessee and subject to the provisions of
Paragraph 16, this Lease shall bind the parties, their personal representatives,
successors and assigns.  This Lease shall be governed by the laws of the State
wherein the Premises are located, in the value of Palm Beach County.

29.  SUBORDINATION.

     (a) This Lease, at Lessor's option, shall be subordinate to any ground
lease, mortgage, deed of trust, or any other hypothecation or security now or
hereafter placed upon the real property of which the Premises are a part and to
any and all advances made on the security thereof and to all renewals,
modifications, consolidations, replacements and extensions thereof.
Notwithstanding such 

                                 Page 14 of 31
<PAGE>
 
subordination, Lessee's right to quiet possession of the Premises, as set forth
in Section 37 of this Lease, shall not be disturbed if Lessee is not in default
and so long as Lessee shall pay the rent and observe and perform all of the
provisions of this Lease, unless this Lease is otherwise terminated pursuant to
its terms. If any mortgagee, trustee or ground lessor shall elect to have this
Lease subordinate to the lien of its mortgage, deed of trust or ground lease,
and shall give written notice thereof to Lessee, this Lease shall be deemed
subordinate to such mortgage, deed of trust, or ground lease, whether this Lease
is dated prior or subsequent to the date of said mortgage, deed of trust or
ground lease or the date of recording thereof.

     (b) Lessee agrees to execute any documents required to effectuate an
attornment, a subordination or to make this Lease subordinate to the lien of any
mortgage deed of trust or ground lease, as the case may be.  Lessee's failure to
execute such documents within 10 days after written demand shall constitute a
material default by Lessee hereunder, or, at Lessor's option, Lessor shall
execute such documents on behalf of Lessee as Lessee's attorney-in-fact.  Lessee
does hereby make, constitute and irrevocably appoint Lessor as Lessee's
attorney-in-fact and in Lessee's name, place and stead, to execute such
documents in accordance with this paragraph 29(b).

30.  ATTORNEY'S FEES.  If either party brings an action to enforce the terms
hereof or declare rights hereunder, the prevailing party in any such action, on
trial or appeal, shall be entitled to his reasonable attorney's fees to be paid
by the losing party as fixed by the court.

31.  LESSOR'S ACCESS.  Lessor and Lessor's agents shall have the right to enter
the Premises at reasonable times for the purpose of inspecting the same, showing
the same to prospective purchasers, lenders, or lessees, and making such
alterations, repairs, improvements or additions to the Premises or to the
building of which they are a part as Lessor may deem necessary or desirable.
Lessor may at any time place on or about the Premises any ordinary "For Sale"
signs and Lessor may at any time during the last 120 days of the term hereof
place on or about the Premises any ordinary "For Lease" signs, all without
rebate of rent or liability to Lessee.

32.  AUCTIONS.  Lessee shall not conduct, nor permit to be conducted, either
voluntarily or involuntarily, any auction upon the Premises without first having
obtained Lessor's prior written consent.  Notwithstanding anything to the
contrary in this Lease, Lessor shall not be obligated to exercise any standard
of reasonableness in determining whether to grant such consent.

33.  SIGNS.  Lessee shall not place any sign upon the Premises.  The Lessee
shall be listed in the Building Directory and shall utilize the standard
building sign at the designated area at or near the entry to its premises.  All
signs must be approved by Lessor.

34.  MERGER.  The voluntary or other surrender of this Lease by Lessee, or a
mutual cancellation thereof or a termination by Lessor shall not work a merger,
and shall, at the option of Lessor, terminate all or any existing subtenancies
or may, at the option of Lessor, operate as an assignment to Lessor of any or
all of such subtenancies.

35.  CONSENTS.  Except for paragraph 32 hereof, wherever in this Lease the
consent of one party is required to an act of the other party, such consent
shall not be unreasonably withheld.

36.  GUARANTOR.  In the event that there is a guarantor of this Lease, said
guarantor shall have the same obligations as Lessee under this Lease.

37.  QUIET POSSESSION.  Upon Lessee paying the rent for the Premises and
observing and performing all of the covenants, conditions and provisions on
Lessee's part to be observed and performed hereunder.  Lessee shall have quiet
possession of the Premises for the entire term hereof subject to all of the
provisions of this Lease.  The individuals executing this Lease on behalf of
Lessor represent and warrant

                                 Page 15 of 31
<PAGE>
 
to Lessee that they are fully authorized and legally capable of executing this
Lease on behalf of Lessor and that such execution is binding upon all parties
holding an ownership interest in the Premises.

38.  RULES AND REGULATIONS.  Lessee agrees that it will abide by, keep and
observe all reasonable rules and regulations which Lessor may make from time to
time for the management, safety, care, and cleanliness of the Building and
grounds, the parking of vehicles and the preservation of good order therein as
well as for the convenience of other occupants and tenants of the Building.  The
violations of any such rules and regulations shall be deemed a material breach
of this Lease by Lessee.

39.  SECURITY MEASURES.  Lessee assumes all responsibility for the protection of
Lessee, its agents and invitees from acts of third parties.

40.  EASEMENTS.  Lessor reserves to itself the right, from time to time, to
grant such easements, rights and dedications that Lessor deems necessary or
desirable, and to cause the recordation of Parcel Maps and restrictions, so long
as such easements, rights, dedications, maps and restrictions do not
unreasonably interfere with the use of the Premises by Lessee.  Lessee shall
sign any of the aforementioned documents upon request of Lessor and failure to
do so shall constitute a material breach of this Lease.

41.  AUTHORITY.  If Lessee is a corporation, trust, or general or limited
partnership, each individual executing this Lease on behalf of such entity
represents and warrants that he or she is duly authorized to execute and deliver
this Lease on behalf of said entity.  If Lessee is a corporation, trust or
partnership, Lessee shall, within thirty (30) days after execution of this
Lease, deliver to Lessor evidence of such authority satisfactory to Lessor.

LESSOR AND LESSEE HAVE CAREFULLY READ AND REVIEWED THIS LEASE AND EACH TERM AND
PROVISION CONTAINED HEREIN AND, BY EXECUTION OF THIS LEASE, SHOW THEIR INFORMED
AND VOLUNTARY CONSENT THERETO.  THE PARTIES HEREBY AGREE THAT, AT THE TIME THIS
LEASE IS EXECUTED, THE TERMS OF THIS LEASE ARE COMMERCIALLY REASONABLE AND
EFFECTUATE THE INTENT AND PURPOSE OF LESSOR AND LESSEE WITH RESPECT TO THE
PREMISES.

The parties hereto have executed this Lease at the place on the dates specified
immediately adjacent to their respective signatures.

     Landlord's Lien

     Lessee acknowledges and agrees that, in addition to any such lien provided
     by law, Lessor has and shall have a Landlord's lien for the rent upon the
     property, fixtures, and improvements of Lessee upon, brought upon, and/or
     found upon the Premises, and said landlord's lien shall be and remain in
     full force and effect continuously and uninterruptedly throughout the term
     of the Lease, including options, extensions and renewals thereof, and any
     such landlord's lien has been, is and shall at all times be superior to any
     claim that any person or entity whatsoever had or has on the Premises and
     any fixtures, property, and/or improvements located on or about the
     Premises, but specifically excluding an existing lien in favor of the Bank
     of New York or any subsequent bank lender to Lessee, which loan document
     pertaining to the lien has been provided to Lessor.  Lessor shall have no
     lien rights on any intellectual property of Lessee.

     In addition to the rent, Lessee agrees to pay Lessor all appropriate sales
     and other taxes as referred to in Paragraph 4.3(g) of the Lease Agreement.

            Atlanta, Georgia 30368-0228

6.   BUILDING EXPENSES.
     ------------------

     A.   During the calendar year 1996, Lessee acknowledges that Building
          Expenses as referred to in paragraph 4.3 of the Lease are estimated at
          $7.80 per square foot plus applicable tax.  Lessee agrees to pay
          Building Expenses plus tax on the first of each month beginning on the
          Lease Commencement Date.

     B.   Lessee acknowledges that all provisions of Paragraph 4.3 of the Lease
          Agreement shall survive the expiration or earlier termination of this
          Lease Agreement.

7.   SERVICES.
     ---------

     A.   Lessor shall furnish the following services without charge, during
          reasonable hours (7:00 a.m. to 7:00 p.m. Monday through Saturday
          inclusive) on normal business days, except National Holidays observed
          by Lessor: (i) elevator service; (ii) common use of restrooms and
          toilets; (iii) cleaning services within both the Premises and the
          Building which notwithstanding (A) above need not be performed during
          business hours or on Saturday and (iv) air conditioning in Lessor's
          judgment sufficient to reasonably cool or heat premises.  Lessee
          acknowledges there may be occasional short term power interruptions
          and other events that may cause temporary loss of air conditioning.
          Air conditioning will be made available to the Premises on Sundays or
          Holidays at an additional charge, with twenty-four (24) hours proper
          notice.

     B.   Lessor shall also furnish electric current on Premises for lighting
          and for business machinery only (e.g., typewriters, computers, word
          processors, photocopiers, kitchen appliances and other small office
          equipment) using 110 volt, 20 AMP circuits, except as provided in
          Exhibit "C'.  Lessee will not use any electrical equipment which in
          Lessor's opinion will overload the wiring installations or interfere
          with the reasonable use thereof by other users in Building.  Lessee
          will not, without Lessor's prior written consent in each instance
          (which shall not be unreasonably withheld) connect any additional
          items to 

                                 Page 19 of 31
<PAGE>
 
          Building's electrical distribution system, or make any
          alteration or addition to such system.  Should Lessor grant such
          consent, all additional circuits or equipment required thereof shall
          be provided by Lessor and the reasonable cost of installation and use
          thereof shall be paid by Lessee upon Lessor's demand.

     C.   If Lessee uses any of the services or electric current enumerated in
          this Paragraph in an amount or for a period in excess of that provided
          for herein, then Lessor reserves the right to charge Lessee as
          additional rent a reasonable sum as reimbursement for the direct cost
          of such added services.  In the event of disagreement as to
          reasonableness of such charge, the opinion of the appropriate local
          utility company or a local independent professional engineer shall
          prevail.

     D.   Except for Lessor's negligence or willful misconduct, Lessor shall in
          no way be liable for cessation of any of the above services caused by
          strike, accident or breakdown, nor shall Lessor be liable for damages
          from the stopping of elevators or elevator service, or any of the
          fixtures or equipment in Building being out of repair, or for injury
          to person or property, caused by any defects in the electrical
          equipment, heating, ventilating and air conditioning system, elevators
          or water apparatus, or for any damages arising out of failure to
          furnish the services enumerated in this Paragraph 7.

     E.   Notwithstanding anything in the contrary in subparagraph 4.3 of the
          Lease Agreement, Lessor shall have the right, at any time, to install
          an electrical metering device to monitor electrical consumption on the
          Premises.  Lessor's right to install a metering device pursuant to
          this subparagraph 7(E) shall be in addition to Lessor's right to
          install such device pursuant to subparagraph 7(B) of this Lease.

     F.   It is understood and agreed that any and all costs and expenses for
          which Lessor bills Lessee and which Lessee is liable to pay to Lessor
          under the provisions of this Paragraph 7 shall be deemed to be
          additional Rent due from Lessee, and any default in the payment
          thereof will entitle Lessor to all remedies provided for herein or at
          law or in equity on account of Lessee's failure to pay rent.

8.   CANCELLATION OPTION.
     --------------------

     Lessee shall have the option to cancel the Lease at the end of the third or
     fourth Lease Year upon giving Lessor notice of at least one hundred eighty

9.   CANCELLATION PENALTY.
     ---------------------

     If Lessee exercises its Cancellation Option, Lessee shall pay Lessor on the
     effective date of such cancellation an amount to reimburse the Lessor for
     the unamortized portion of leasing commissions and tenant improvements.
     Such amount will be amortized based upon a sixty (60) month term at ten
     percent (10%) interest.  Such Cancellation Penalty amounts are broken down
     as follows:

                                                                     $34,229.93

10.  OPTION TO RENEW.
     ---------------

     Provided Lessee is not in default, Lessor will provide Lessee with one,
     three (3) year option to renew the Lease.  Such renewal will be on the same
     terms and conditions of the primary lease except the base rental rate will
     be the greater of the then current market rate for comparable office
     buildings in Boca Raton or one hundred four percent (104%) above the base
     rental rate being paid in the last Lease Year of the primary term.  The
     base rental rate shall increase each subsequent year during such renewal
     period by an amount equal to one hundred four percent (104%) of the Base
     Monthly Rent for the Lease Year immediately preceding the increase.  Lessee
     must notify Lessor in writing of its intent to exercise this option at
     least one hundred twenty (120) days, but in no event more than one hundred
     eighty (180) days, prior to the expiration of the initial lease term.

     ----------------------

     Provided Lessee is not in default, Lessor shall provide Lessee an ongoing
     Right of First Refusal on any contiguous space that may become available
     during the term of the Lease.  Upon the Lessor's intent to offer any
     contiguous space for lease to any prospect, Lessor shall offer to Lessee an
     option to expand into such space based upon the terms currently being
     offered for the space.  Lessor shall notify Lessee, in writing, of its
     intent to offer such space and Lessee shall have three (3) business days
     from receipt of such notice to accept such premises under the terms and
     conditions being offered.

12.  OCCUPANCY DATE.
     --------------

     Lessee shall have full use of the premises upon the issuance of a
     Certificate of Occupancy ("CO").  Commencing upon such date as the "CO" is
     issued, Lessee shall be obligated by all terms and conditions of the Lease.
     Notwithstanding anything to the contrary, Lessee shall not be obligated to
     pay base rent as stipulated in Section 4.1 until December 1, 1996.  Lessee
     shall be obligated to pay their proportionate share of Building Expenses
     upon the date the "CO" is issued.

13.  BUILDING EXPENSES.
     -----------------

     Notwithstanding anything to the contrary, Lessee shall be responsible for
     up to a maximum five percent (5%) per annum increase on a cumulative basis
     for Building Expenses, exclusive of real estate taxes and/or special
     assessments, insurance, and utilities, which includes waste removal.  Such

                             RULES AND REGULATIONS
                             ---------------------

1.   The rights of Lessees in the entrances, corridors and elevators of the
     Building are limited to ingress to and egress from the Lessees' premises
     for the Lessees and their employees, licensees and invitees, and no Lessee
     shall use, or permit the use of, the entrances, corridors, or elevators for
     any other purpose.  No Lessee shall invite to the Lessee's premises or
     permit the visit of, persons in such numbers or under such conditions as to
     interfere with the use and enjoyment of any of the plazas, entrance,
     corridors, elevators and other facilities of the Building by other lessees.
     No Lessee shall encumber or obstruct, or permit the encumbrance or
     obstruction of any of the sidewalks, plazas, entrances, corridors,
     elevators, fire exits or stairways of the Building.  The Lessor reserves
     the right to control and operate the public portions of the Building and
     the public facilities, as well as facilities furnished for the common use
     of the Lessees, in such manner as it deems best for the benefit of the
     Lessees generally.  Lessor is not responsible for any "down time" or other

     business hours, to any person not having a pass or key issued by the Lessor
     or the Lessee whose premises are to be entered or not otherwise properly
     identified, and may require all persons admitted to or leaving the Building
     outside of ordinary business hours to register.  Any person whose presence
     in the Building at any time shall, in the judgment of the Lessor, be
     prejudicial to the safety, character, reputation and interests of the
     Building or of its Lessees may be denied access to the Building or may be
     ejected therefrom.  In case of invasion, riot, public excitement or other
     commotion the Lessor may prevent all access to the Building during the
     continuance of the same, by closing the doors or otherwise, for the safety
     of the Lessees and protection of property in the Building.  The Lessor may
     require any person leaving the Building with any package or other object to
     exhibit a pass from the Lessee from whose premises the package or object is
     being removed, but the establishment and enforcement of such requirement
     shall not impose any responsibility on the Lessor for the protection of any
     Lessee against the removal of property from the premises of the Lessee.
     The Lessor shall in no way be liable for any Lessee for damages or loss
     arising from the admission, exclusion or ejection of any person to or from
     the Lessee's premises or the Building under the provisions of this rule.

     Lessee shall cooperate to prevent the same.

     Lessee, shall be paid by such Lessee.

5.   No lettering, sign, advertisement, notice or object shall be displayed in

     at any point inside any Lessee's premises where the same might be visible
     outside of such premises, except that the name of the Lessee may be
     displayed on the entrance door of the Lessee's premises, and in the
     elevator lobbies of the floors which are occupied entirely by any Lessee,
     subject to the approval of the Lessor as to the size, color and style of

     equipment into or out of the Building.  Only service elevators designated
     by Lessor will be utilized for such activities.  In particular, no freight,
     furniture, business equipment, merchandise or other bulky matter may be
     delivered to or removed from the premises without the express written

     disturbing noise, vibration or electrical or other interference from being
     transmitted from such premises to any other area of the Building.

     Lessees in the Building, shall be made or permitted by any Lessee, and no
     cooking (excluding a microwave oven) shall be done in the Lessee's
     premises, except as expressly approved by the Lessor.  Nothing shall be
     done or permitted in any Lessee's premises, and nothing shall be brought
     into or kept in any Lessee's premises, which would impair or interfere with
     any of the Building services or the proper and economic cleaning or other
     servicing of the Building or the premises, nor shall there be installed by
     any Lessee any ventilating, air conditioning, electrical or other equipment
     of any kind, except in the Porting Lab and Stratus Rooms, which, in the
     judgment of the Lessor, might cause any such impairment or interference.
     No dangerous, inflammable, combustible or explosive object or material
     shall be brought into the Building by any Lessee or with the permission of
     any Lessee.  Any cuspidors or similar containers or receptacles used in any

     doors or windows in any Lessee's premises and no lock on any door therein
     shall be changed or altered in any respect.  Additional keys for a Lessee's
     premises shall be procured only from the Lessor, which may make

                                 Page 29 of 31

     a reasonable charge therefor. Upon the termination of the Lessee's lease,
     all keys of the Lessee's premises shall be delivered to the Lessor.

12.  All entrance doors in each Lessee's premises shall be left locked by the
     Lessee when the Lessee's premises are not in use.  Entrance doors shall not

        Section 1.4     Interest.  (a)  Rates.  Each Loan shall bear interest on
                        --------        -----

Event of Default (and whether before or after judgment), each Loan (whether or 
not due) and to the maximum extent permitted by Applicable Law, each other 
amount due and payable under the Borrower Loan Documents shall bear interest at
a rate per annum equal to the applicable Post-Default Rate.

                (b)     Payment.  Interest shall be payable in arrears on each

exceeding the Maximum Permissible Rate.  If interest payable by the Borrower on
any date would exceed the maximum amount permitted by the Maximum Permissible 
Rate, such interest payment shall automatically be reduced to such maximum 
permitted amount, and interest for any subsequent period, to the extent less 
than the maximum amount permitted for such period by the Maximum Permissible 
Rate, shall be increased by the unpaid amount of such reduction.  Any interest 
actually received for any

prepaid.  Amounts to be prepaid pursuant to this Section 1.6(a) shall 
irrevocably be due and payable on the date specified in the applicable notice of
prepayment, together with interest thereon as provided in Section 1.4(b).

                (b)     Mandatory Prepayments.  If at any time the aggregate

                        --------------------------------------------------
Commitment.  (a)  The Borrower shall pay to the Bank a commitment fee on the 
- ----------
daily unused amount of the Commitment for each day from the Agreement Date 
through the Termination Date at a rate per annum of 1/2%, payable on the last 
day of each fiscal quarter of the Borrower, on the Termination Date and on the

of Credit (the "Letter of Credit Fee") at the rate of two percent (2%) per

                        -----

additional amounts as may be necessary so that the net amount received by the
Bank with respect to such payment, after withholding or deducting all Taxes
required to be withheld or deducted, is equal to the full amount payable under
the Borrower Loan Documents and (B) an amount equal to all Taxes payable by the
Bank as a result of payments made by the Borrower (whether to a taxing authority
or to the Bank) pursuant to this Section 1.9(c). If any Tax is withheld or

payment due to the Bank under the Borrower Loan Documents, the Borrower shall,
within thirty (30) days after the date of such payment, furnish to the Bank the

therefrom, or otherwise paying in connection therewith, any Tax payable to any
taxing authority, the Borrower shall, within 30 days after any request from the
Bank, furnish to the Bank a certificate from such taxing authority, or an
opinion of counsel acceptable to the Bank, in either case stating that no Tax
payable to such taxing authority was or is, as the case may be, required to be

its Affiliates (whether maintained at a branch or office located within or

deficiency.

                (e)     Extension of Payment Dates.  Whenever any payment to the
                        --------------------------
Bank under the Borrower Loan Documents would otherwise be due (except by reason
of acceleration) on a day that is not a Business Day, such payment shall instead
be due on the next succeeding Business Day.  If the date any payment under the 
Borrower Loan Documents is due is extended (whether by operation of any Borrower
Loan Document, Applicable Law or otherwise), such payment shall bear interest 
for such extended time at the rate of interest applicable hereunder.

Bank, the Bank or any Affiliate of the Bank is required, under Applicable Law,

determined in accordance with a method specified, by the Bank.

contemplated by Sections 7.1 and 7.2, the Bank may make such estimates, 
assumptions, allocations and the like that the Bank in good faith determines to

respect to a Lending Office that entitles the Bank to make a claim under 
Section 7.1 or 7.2, the Bank shall, if requested by the Borrower, use 
reasonable efforts to designate another Lending Office or Offices the 
designation of which will eliminate such operability or reduce the amount the 
Bank is so entitled to claim, provided that such designation would not, in the 
sole and absolute discretion of the Bank, be disadvantageous to the Bank in any 
manner or contrary to Bank policy.  The Bank may at any time and from time to 
time change any Lending Office and shall give notice of any such change to the 
Borrower.  Except in the case of a change in Lending Offices made at the request
of the Borrower, the designation of a new Lending Office by the Bank shall not 
entitle the Bank to make a claim under Section 7.1 or 7.2 if the operability of 
such clause or such claim results solely from such designation and not from a 
subsequent Regulatory Change.

                WHEREAS, the Borrower and the Bank wish to amend certain 
provisions of the Credit Agreement.

                NOW, THEREFORE, for good and valuable consideration, the receipt
and sufficiency of which are hereby acknowledged, the Borrower and the Bank 
agree as follows:

                1.      Section 1.1 of the Credit Agreement is hereby deleted in
its entirety and replaced with the following:

                Section 1.1     Commitment to Lend.  Upon the terms and subject 
                                ------------------
        to the conditions of this Agreement, the Bank agrees to make, from time
        to time during the period from the Agreement Date through the 
        Termination Date, one or more Loans to the Borrower in an aggregate 
        unpaid  principal amount not exceeding at any time the lesser of (a) the
        Commitment at such time (which amount includes the aggregate stated 
        amount of Letters of Credit issued for the account of the Borrower) and 
        (b) the Borrowing Base at such time.  Subject to Section 1.11 and the 
        other terms and conditions of this Agreement, the Loans may, at the 
        option of the Borrower, be made as, and from time to time continued as 
        or converted into, Prime Rate Loans or LIBOR Rate Loans of any permitted
        Type, or any combination thereof.  The Loans will be made at the rate of
        interest established pursuant to the terms of Section 1.4 below.  The 
        amount of the Commitment on the Agreement Date is $4,000,000.

                2.      Section 1.2 of the Credit Agreement is hereby deleted in
its entirety and replaced with the following:

                Section 1.2     Manner of Borrowing.    (a)  The Borrower shall
                                -------------------
        give the Bank notice (which shall be irrevocable) no later than 10:00
        a.m. (New York time) on, in the case of Prime Rate Loans, the Business
        Day, and, in the case of LIBOR Rate Loans, the second Business Day,
        before the requested date for the making of a Loan.  Each such notice

                                      -1-
<PAGE>
 
        shall be in the form of Schedule 1.2 and shall specify (i) the requested
                                ------------
        date for the making of the requested Loan, which shall be a Business 
        Day,(ii) the Type or Types of Loans requested and (iii) the amount of 
        each such Type of Loan, which amount shall be, in the case of each such 
        Type of Loan, not less than $50,000 and in multiples of $50,000, or, if 
        less, the maximum amount that can then be borrowed hereunder.  Each Loan
        so requested shall be disbursed by the Bank not later than 12:00 noon 
        (New York time) on the requested date therefor in Dollars in funds
        immediately available to the Borrower by credit to an account of the
        Borrower at the Bank's Office or in such other manner as may have been
        specified in the applicable notice and as shall be acceptable to the
        Bank.

                (b)     At the time of any drawing under a Letter of Credit, the
        resulting reimbursement obligation of the Borrower (regardless of
        whether the amount complies with the requirements of Section 1.2(a)
        (iii)) shall immediately become a Prime Rate Loan and no notice of
        borrowing as described in Section 1.2(a) shall be required.

                3.      Section 1.4 of the Credit Agreement is hereby amended by
deleting sections (a) and (b) in their entirety and replacing them with sections
(a) and (b) below, and by adding a new section (d), as set forth below:

                (a)     Rates.  Each Loan shall bear interest on the outstanding
                        -----
        principal amount thereof until due at a rate per annum equal to, (i) so
        long as it is a Prime Rate Loan, the Alternative Base Rate as in effect
        from time to time plus 1.00%, and (ii) so long as it is a LIBOR Rate
        Loan, the LIBOR Rate applicable thereto plus 3.00%.  During an Event of
        Default (and whether before or after judgment), each Loan (whether or
        not due) and to the maximum extent permitted by Applicable Law, each
        other amount due and payable under the Borrower Loan Documents, shall
        bear interest at a rate per annum equal to the applicable Post-Default
        Rate.

                (b)     Payment.  Interest shall be payable in arrears, (i) in
                        -------
        the case of Prime Rate Loans, on each Interest Payment Date, and (ii) in
        the case of LIBOR Rate Loans, on the last day of each applicable
        Interest Period (and, if an Interest Period is longer than 90 days, at
        intervals of 90 days after the first day of such Interest Period) and
        (iii) in the case of any Loan, when such Loan shall be due (whether at
        maturity, by reason of notice of prepayment or acceleration or
        otherwise).  Notwithstanding the foregoing, interest at the Post-Default
        Rate shall be payable on demand.

                (d)     Conversion and Continuation.  (i) All or any part of the
                        ---------------------------
        principal amount of Loans of any Type may, on any 

                                      -2-

        Business Day, be converted into any other Type or Types of Loans,
        subject to the provisions of this Section 1.4(d).

                (ii)    Each Prime Rate Loan shall continue as a Prime Rate Loan
        unless and until such Loan is converted into a Loan of another Type.
        Each LIBOR Rate Loan of any Type shall continue as a Loan of such Type
        until the end of the then current Interest Period therefor, at which
        time it shall be automatically converted into a Prime Rate Loan unless
        the Borrower shall have given the Bank notice in accordance with Section
        1.4(d)(iv) requesting either that such Loan continue as a Loan of such
        Type for another Interest Period or that such Loan be converted into a
        Loan of another Type at the end of such Interest Period.

                (iii)   Notwithstanding anything to the contrary contained in
        Section 1.4(d)(i) or (ii), during a Default, the Bank may notify the
        Borrower that Loans may only be converted into or continued as Loans of
        certain specified Types and, thereafter, until no Default shall continue
        to exist, Loans may not be converted into or continued as Loans of any
        Type other than one or more of such specified Types.

                (iv)    The Borrower shall give the Bank notice (which shall be
        irrevocable) of each conversion of a Loan or continuation of a LIBOR
        Rate Loan no later than 10:00 a.m. (New York time) on, in the case of a
        conversion into or a continuation of a Prime Rate Loan, the Business 
        Day, and, in the case of a conversion into or continuation of a LIBOR 
        Rate Loan, the second Business Day, before the requested date of such
        conversion or continuation.  Each notice of conversion or continuation
        shall be in the form of Schedule 1.4(d) (iv) and shall specify (A) the

        prepayment shall be in an aggregate principal amount of at least $50,000

        a.m. (New York time) on, in the case of a prepayment of a Prime Rate
        Loan, the Business Day, and, in the case of a prepayment of a LIBOR Rate
        Loan, the second Business Day, before the date of such prepayment.  Each
        such notice of prepayment shall be in the form of Schedule 1.6(a) and

        unpaid principal amount of the Loans exceeds the Borrowing Base, the
        Borrower shall immediately prepay the Loans in an amount not less than
        the amount of such excess.  Amounts prepaid pursuant to this Section
        1.6(b) shall be applied first to prepay Prime Rate Loans and then to
        prepay LIBOR Rate Loans in the order that the Interest Periods for such
        Loans end.  Amounts to be prepaid pursuant to this Section 1.6(b) shall
        be paid within the time period specified therefor, whether or not such
        payment would require a prepayment of a LIBOR Rate Loan prior to the
        last day of an applicable Interest Period or would result in losses,
        costs or expenses compensable under Section 7.6.

        case of a change in Lending Offices made at the request of the Borrower,
        the designation of a new Lending Office by the Bank shall not make
        operable the provisions of clause (b) or (c) of Section 7.5 or entitle
        the Bank to make a claim under Section 7.1 or 7.2 if the operability of
        such clause or such claim results solely from such designation and not
        from a subsequent Regulatory Change.

                18.     Two new sections of the Credit Agreement, Sections 7.5
and 7.6, are hereby inserted following Section 7.4 of the Credit Agreement as
set forth below:

                Section 7.5     Mandatory Suspension and Conversion of Fixed
                                --------------------------------------------
        Rate Loans.  The Bank's obligations to make, continue or convert into
        ----------
        LIBOR Rate Loans of any Type shall be suspended, all outstanding Loans
        of that Type shall be converted on the last day of their applicable
        Interest Periods (or, if earlier, in the case of clause (b) below, on
        the last day the Bank may lawfully continue to maintain Loans of that
        Type or, in the case of clause (c) below, on the day determined by the
        Bank to be the last Business Day before the effective date of the
        applicable restriction) into, and all pending requests for the making
        or 

                                      -8-
<PAGE>
 
        continuation of or conversion into Loans of such Type shall be deemed
        requests for, Prime Rate Loans, if:

                (a)  on or prior to the determination of an interest rate for a
        LIBOR Rate Loan of that Type, the Bank determines that for any reason 
        such LIBOR Rate would not accurately reflect the cost to the Bank of
        making, continuing or converting into a LIBOR Rate Loan for such
        Interest Period;

                (b)  at any time the Bank determines that any Regulatory Change
        makes it unlawful or impracticable for the Bank or a Lending Office to
        make, continue or convert into any LIBOR Rate Loan of that Type, or to
        comply with its obligations hereunder in respect thereof; or

                (c)  the Bank determines that, by reason of any Regulatory
        Change, the Bank or a Lending Office is restricted, directly or
        indirectly, in the amount that it may hold of (i) a category of
        liabilities that includes deposits by reference to which, or on the
        basis of which, the interest rate applicable to LIBOR Rate Loans of that
        Type is directly or indirectly determined or (ii) the category of assets
        that includes LIBOR Rate Loans of that Type.

        The Bank shall promptly notify the Borrower of any circumstance that
        would make the provisions of this Section 7.5 applicable, but the
        failure to give any such notice shall not affect the Bank's rights
        hereunder.

                Section 7.6     Funding Losses.  The Borrower shall pay to the
                                --------------
        Bank, upon the Bank's written request, such amount or amounts as the
        Bank determines are necessary to compensate it for any loss, cost or
        expense incurred by it as a result of (a) any payment, prepayment or
        conversion of a LIBOR Rate Loan on a date other than the last day of
        an Interest Period for such LIBOR Rate Loan or (b) a LIBOR Rate Loan 
        for any reason not being made or converted, or any payment of principal
        thereof or interest thereon not being made, on the date therefor
        determined in accordance with the applicable provisions of this
        Agreement.  At the election of the Bank, and without limiting the
        generality of the foregoing, but without duplication, such compensation
        on account of losses may include an amount equal to the excess of (i)
        the interest that would have been received from the Borrower under this
        Agreement on any amounts to be reemployed during an Interest Period or
        its remaining portion over (ii) the interest component of the return
        that the Bank determines it could have obtained had it placed such
        amount on deposit in the interbank Dollar market selected by it for a
        period equal to such Interest Period or its remaining portion.

Pledgor shall, should it receive any such proceeds or Distribution Collateral, 
hold all such proceeds and Distribution Collateral in trust for the Secured 
Party, not commingle the same with other property or funds of the Pledgor and, 
unless the Secured Party shall have otherwise instructed the Pledgor, deliver 
the same or cause the same to be delivered in the exact form received, together
with any necessary endorsements, to the 

                                      -4-
<PAGE>

                     ----------------------
that constituted the proceeds of property insurance subject to Section

the Authority to issue to eligible institutions guarantees of loans and other

interest in all of its property to the Lender to secure the repayment of its

Lender shall provide a fully executed copy of the Lender Loan Documents to 
counsel for the Authority, in order for such counsel to confirm on behalf of the
Authority that the Lender Loan Documents are consistent with the Guarantee
Request and the Commitment and are adequate to fully protect and preserve 

                                      -7-
<PAGE>
 
the interests of the Authority with respect to the Lender Loan. Upon
satisfactory review of such Lender Loan Documents by counsel to the Authority,
the Lender Loan Documents shall be deemed to be in accordance with the terms and
conditions set forth in the Guarantee Request and Commitment for the Lender Loan
unless Lender (i) modifies any of the approved documents other than as permitted

Documents, or (iii) fails to file or cause to be filed such financing
statements, mortgages and other security documents (collectively the "Security

offices or with the authorities noted on the Security Filings, or file such
continuation statements, mortgages and other security documents as are necessary

security interests evidenced by the Security Filings. If (i), (ii) or (iii)
shall occur, the Authority may exercise its rights under Section 15 hereof.
Lender Loan Documents shall include an opinion of Borrower's counsel
satisfactory to Authority counsel, which shall provide that it may be relied
upon by any participant in or purchaser of the Lender Loan, including the
Authority. Execution and delivery by the Authority of this Guarantee shall be
deemed conclusive evidence of such satisfactory review by counsel to the
Authority

                                      -8-
<PAGE>
 
and of the approval of the closing activities to the time of the delivery of
this Guarantee.

        Promptly after closing, Lender shall deliver a copy of the Lender Loan 
Documents to the Authority.  The Authority shall be entitled at any time during
regular business hours, upon reasonable advance written notice to the Lender, 
to inspect any of the Lender Loan Documents or other documents relating to the 
Lender Loan which are in the Lender's possession, including without limitation,
repayment records.

        Section 4.      Lender Loan Servicing.  Lender shall have the sole right
                        ---------------------
to service the Lender Loan at all times except as provided in Section 12.  
Lender shall exercise substantially the same care in administering, servicing 
and managing the Lender Loan as it exercises with respect to similar loans made
or held by Lender, and will employ its customary practices to collect all 
payments from the Lender Loan and will perform all customary servicing 
responsibilities with respect to the Lender Loan.  Lender's customary and usual
servicing practices include, without limitation, (i) the receipt and review of 
financial statements; (ii) the receipt and review of insurance policies, reports
and certificates; (iii) inspection of plant, property and equipment; and (iv) 
monitoring of assets taken as collateral.

        Section 5.      Reports to the Authority.  Within fifteen days from the
                        ------------------------
last day of each December, March, June and September, 

                                      -9-
<PAGE>
 
Lender shall provide the Authority with a quarterly report for the quarter
ending on such day with respect to the Lender Loan, in the form attached hereto
as Exhibit A.

        Lender shall deliver to the Authority, promptly after receipt of a 
written request by the Authority, copies of all financial statements, insurance
policies and certificates, environmental reports, accounts receivable and 
inventory reports, and other material documentation as shall have been delivered
by or on behalf of the Borrower, to the extent retained by the Lender.  Lender 
shall also provide the Authority with a copy of each and every written notice of
demand, acceleration or default, legal summons or process sent to or served upon
the Borrower by the Lender and every other written communication to or from the 
Borrower which, in Lender's reasonable judgment, materially and adversely 
affects any interest of the Authority.  Nothing in this Section shall be deemed
to require Lender to disclose any information which it is prohibited by law from
disclosing.

        Section 6.      No Warranty by Lender.  Lender shall not be deemed to
                        ---------------------
have made any covenant, warranty or representation with respect to the ability 
of the Borrower to repay the Lender Loan or the truth, accuracy or completeness 
of any report, statement or certificate now or hereafter given by the Borrower 
in connection with the Lender Loan.  Lender will exercise substantially the same
care in administering the Lender Loan as 

                                      -10-
<PAGE>
 
it exercises with respect to similar loans made or held by Lender.

        Section 7.      Changes to Lender Loan Documents.  Lender shall not, 
                        --------------------------------
without the prior written consent of the Authority, which consent shall be given
promptly, commensurate with the nature of the request, (i) enter into any 
amendment, modification, supplement or replacement of any Lender Loan Document 
which would materially and adversely affect the Authorities rights hereunder; 
(ii) otherwise make or consent to any increase in the principal amount of the 
Lender Loan, any change in interest rate on the Lender Loan not contemplated by
the Lender Loan Documents, any change in the maturity of the Lender Loan, or any
change in the principal amortization schedule for the Lender Loan, except as set
forth below; (iii) waive or release any claim against Borrower arising out of or
under any Lender Loan Document; or (iv) make or consent to releases of any 
collateral securing the Lender Loan, unless (A) the sum of the fair market value
of such collateral, as reasonably determined by Lender, and the fair market 
value, as reasonably determined by Lender, of all collateral previously released
does not exceed one percent (1%) of the original principal amount of the Lender
Loan, (B) the Borrower or any other entity pledges or grants to the Lender a 
security interest and lien on substitute collateral of equal or greater fair 
market value, as reasonably determined by Lender, than such released collateral,
or (C) the Lender receives payment 

                                      -11-
<PAGE>
 
on the Lender Loan in connection with such release of an amount equal to or
greater than the fair market value, as reasonably determined by Lender, of such
released collateral.

        Notwithstanding the foregoing, Lender shall have the right, without the
consent of the Authority, to extend the maturity of the Lender Loan or modify 
the principal amortization of the Lender Loan so that the outstanding principal
balance of the Lender Loan is reduced more slowly than the Scheduled 
Amortization Loan Balance; provided, however, that in the event Lender so 
extends the maturity or modifies the principal amortization without the consent
of the Authority, the Guarantee Amount shall continue to be reduced in 
proportion to the reduction in the Scheduled Amortization Loan Balance in 
accordance with the terms of Section 8 hereof as if no such modification shall 
have occurred.

        The Lender shall promptly furnish to the Authority copies of each and 
every written amendment, waiver or consent entered into or given with respect to
any Lender Loan Document, whether or not the Authority's consent thereto is 
required hereunder.

        Section 8.      Guarantee Amount.  The Guarantee Amount at any given 
                        ----------------
time shall be equal to (i) thirty percent (30%) of the lesser of (a) the then 
outstanding principal balance of the Lender Loan or (b) the Scheduled 
Amortization Loan Balance as of such date, minus (ii) the total of all payments
theretofore made by the Authority under this Guarantee.  Upon any payment by the

                                      -12-
<PAGE>
 
Authority under its Guarantee (other than payments pursuant to the Authority's 
cure rights described in Section 9 which are not allocated to principal on the 
Lender Loan), the Guarantee Amount shall be immediately and automatically 
reduced by the amount of such payment, except that the Guarantee Amount may be 
reinstated as provided in Section 9 hereof.  Notwithstanding the foregoing, the
Guarantee Amount shall automatically reduce to zero and this Guarantee shall 
terminate on a date two years from the date hereof, unless a demand on this 
Guarantee is outstanding on such date; provided, however, that in the event that
an Authority Cure Period is in effect on such date, the Guarantee Amount shall 
not reduce to zero and this Guarantee shall not terminate until forty-five (45)
days after the end of such Authority Cure Period.

        Section 9.      Procedures upon Default.  In the event that there shall
                        -----------------------
occur and continue any event of default as defined in the Lender Loan Documents
and such event of default shall have been declared by Lender (ar "Event of 
Default"), Lender shall give written notice to the Authority of such Event of 
Default prior to enforcing any of its rights or exercising any of its remedies 
under the Lender Loan Documents with respect to such Event of Default, 
including, without limitation, acceleration of the maturity of the indebtedness
evidenced thereby, and in any event no later than forty-five (45) days after the
Lender shall first have declared such Event of Default.  After providing such 
notice to the Authority, Lender shall, except as provided in the 

                                      -13-
<PAGE>
 
next sentence below, further forbear from enforcing any of its rights or
exercising any of its remedies under the Lender Loan Documents (other than the
exercise of any right of set-off or garnishment), including, without limitation,
acceleration of the maturity of the indebtedness evidenced thereby, for an
additional period of thirty (30) days (the "Authority Cure Period"), commencing
on the date the Authority receives such notice, unless the Authority, by written
notice to Lender, elects to terminate the Authority Cure Period on an earlier
date. Notwithstanding the foregoing, there shall be no Authority Cure Period and
Lender shall be entitled to enforce its rights and exercise its remedies under
the Lender Loan Documents at any time after notifying the Authority of an Event
of Default if (i) Lender reasonably believes that there has been fraud,
conversion or other irregularities committed by the Borrower with respect to the
Lender Loan, (ii) Lender reasonably anticipates that its loss on the Lender
Loan, after foreclosure of the collateral securing the Lender Loan and
enforcement by Lender of its other rights and remedies under the Lender Loan
Documents with respect thereto, but not taking into account any payment by the
Authority on its Guarantee, will exceed ten percent (10%) of the outstanding
principal balance of the Lender Loan at the time Lender provides notice to the
Authority of such Event of Default or (iii) any insolvency or bankruptcy
relating to the Borrower or all or substantially all of its assets shall have
been commenced (each of (i), (ii) and (iii) above a "Cure Termination Event");

                                      -14-
<PAGE>
 
provided, however, that in any such event Lender shall give written notice 
- --------  -------
thereof to the Authority at the time it notifies the Authority of such Event of
Default.

        During the Authority Cure Period, the Authority shall have the right, 
but not the obligation, to cure any Event of Default which results from the 
Borrower's failure to pay principal of or interest on the Lender Loan or any 
other amount due under the Lender Loan Documents by making payment of such 
amount.  The portion of any such payment by the Authority applicable to 
principal of the Lender Loan shall be deemed made under this Guarantee, and 
shall reduce the Guarantee Amount by the amount of such principal payment.  If 
the Authority elects to make a payment or payments curing an Event of Default 
during the Authority Cure Period, the Authority may, but shall be under no 
obligation to, continue such payments for a period of up to six (6) consecutive
months from the date the Authority first received notice of such Event of 
Default, and the Authority Cure Period shall, for all purposes hereunder, 
continue while such payments are being made; provided, however, that if at any 
time during such six month period a Cure Termination Event occurs or is 
discovered by Lender, Lender may provide written notice thereof to the Authority
and the Authority's Cure Period shall terminate upon receipt of such notice.  
The Authority shall be entitled to recover from the Borrower all sums paid with
respect to the Lender Loan by the Authority pursuant to its right to cure, so 
long as no other Event of Default has occurred and so long as a 

                                      -15-
<PAGE>
 
recovery would not result in another Event of Default, and further that such
right of recovery is subordinate to Lender's rights to payment in full of the
Lender Loan. In the event that the Authority recovers all such sums, plus
interest at the rate on the Lender Loan and all costs and expenses incurred in
connection therewith, then the Authority shall reinstate its Guarantee of the
Lender Loan to the amount that would otherwise have been in effect on the date
of such reinstatement if the Event of Default had not occurred.

        In addition to the foregoing, the Authority shall have the right, but 
not the obligation, at any time during the Authority Cure Period, to make 
payment to Lender of all amounts outstanding under the Lender Loan Documents, 
and thereupon the Authority shall be deemed to have purchased and shall succeed
to the rights and interests of Lender under the Lender Loan Documents.  In the
event that the Authority so purchases the rights and interests of Lender under 
the Lender Loan Documents, Lender shall execute and deliver such assignments and
other documents as the Authority shall reasonably request to reflect such 
purchase by the Authority, such assignments to be without recourse, 
representation or warranty to or by the Lender.

        In the event that an Event of Default under such Lender Loan Documents 
has occurred and the Authority Cure Period for such Event of Default is not 
applicable, or has expired without such Event of Default being cured, then 
Lender shall thereafter be free to enforce its rights and exercise its remedies
under the 

                                      -16-
<PAGE>
 
Lender Loan Documents without the consent of the Authority and shall be free to
make demand upon the Authority under its Guarantee, on the terms and subject to
the conditions set forth in Section 10 hereof.

        Section 10.     Payment of Estimated Loss.  In the event that (i) an 
                        -------------------------
Event of Default has occurred, (ii) the Authority Cure Period for such Event of
Default has expired without cure of such Event of Default (or the Authority Cure
Period is not applicable) and (iii) either (A) Lender has accelerated the 
maturity of the Lender Loan or (B) Lender cannot accelerate the maturity of the
Lender Loan because a proceeding under the Federal Bankruptcy laws is pending 
with respect to the Borrower, then Lender shall be entitled to demand, and the 
Authority shall be obligated to make, payment under the Guarantee, which payment
shall equal that portion of the Guarantee Amount or Estimated Loss as is 
described below.  Lender shall make such demand on the Authority by delivering 
to the Authority a statement, which shall indicate Lender's estimated loss on 
the Lender Loan based on a liquidation of the collateral securing the Lender 
Loan and enforcement by Lender of its other rights and remedies under the Lender
Loan Documents (the "Estimated Loss"), shall contain such qualifications, 
limitations, and assumptions as Lender shall reasonably deem necessary, and 
shall include (i) the most recent appraisal in the Lender's possession of all 
fixed asset collateral for the Lender Loan and (ii) a statement of the 

                                      -17-
<PAGE>
 
methodology used by Lender in determining the value of all other collateral.  
Upon delivery of such a statement, Lender shall be entitled to receive under 
this Guarantee eighty percent (80%) of the lesser of (i) the Estimated Loss and
(ii) the Guarantee Amount as of the date that Lender notified the Authority of 
the Event of Default, less any unreimbursed payments on this Guarantee since 
such date.  The Authority will make payment to Lender of such amount within 
thirty (30) days of delivery of such statement.  Any payment by the Authority of
all or any portion of the Guarantee Amount shall permanently and irrevocably 
reduce the Guarantee Amount by the amount of such payment in accordance with the
provisions of Section 8, but subject to reinstatement pursuant to Section 9.

        Section 11.     Lender Recovery and Payment of Final Loss.  In the event
                        -----------------------------------------
that the Authority has made a payment to Lender pursuant to this Guarantee, 
Lender shall pursue enforcement of such rights and remedies of Lender under the
Lender Loan Documents in accordance with prudent and customary bank practices, 
including, without limitation, foreclosure against collateral securing the 
Lender Loan, as and to the extent that the enforcement of such rights and 
remedies would be prudent and commercially reasonable for Lender to pursue if it
were acting solely for its own account in order to realize the maximum recovery
on the Lender Loan. After Lender reasonably believes there is no reasonable 
prospect for any further material 

                                      -18-
<PAGE>
 
recovery, Lender shall provide a written certification to the Authority stating
that there is no reasonable prospect for any further material recovery and
setting forth (i) the total principal, interest and Liquidation Costs then due
and owing under the Lender Loan Documents with respect to the Lender Loan (the
"Total Indebtedness"), and (ii) the aggregate amount recovered by the Lender
under the Lender Loan Documents which the Lender is entitled to retain (the
"Recoveries"). In the event that the sum of (i) the Recoveries and (ii) all
amounts previously paid by the Authority under this Guarantee exceed the Total
Indebtedness, then Lender shall promptly remit to the Authority the amount of
such excess, provided that the Authority shall not be entitled to receive from
Recoveries amounts in excess of all amounts paid by the Authority under this
Guarantee. In the event that the sum of (i) the Recoveries and (ii) all amounts
previously paid by the Authority under this Guarantee is less than the Total
Indebtedness, then the Authority shall promptly remit to Lender the lesser of
(x) such difference and (y) the Guarantee Amount as of the date Lender notified
the Authority of the Event of Default pursuant to Section 9 hereof, less all
unrecovered payments made by the Authority on this Guarantee since such date. If
at any time after such settlement, Lender realizes additional Recoveries such
that the sum of (i) all Recoveries realized by the Lender and (ii) all amounts
paid by the Authority under this Guarantee exceeds the Total Indebtedness,
Lender shall notify the Authority of such excess 

                                      -19-
<PAGE>
 
and shall promptly remit to the Authority the same, provided that the Authority
shall not be entitled to receive from Recoveries amounts in excess of all
amounts paid by the Authority under this Guarantee. Similarly, if at any time
Lender receives any Recoveries which Recoveries or any part thereof are
subsequently invalidated, declared to be fraudulent or preferentially set aside
and/or required to be repaid to a trustee, receiver or any other party under any
bankruptcy laws, state or federal law, common law or equitable doctrine, to the
extent that the sum of (i) all Recoveries actually retained by the Lender and
(ii) all amounts paid by the Authority under this Guarantee is less than the
Total Indebtedness, Lender shall so notify the Authority and the Authority shall
promptly remit to Lender the lesser of (x) such difference and (y) the Guarantee
Amount as of the date Lender notified the Authority of the Event of Default
pursuant to Section 9 hereof, less all unreimbursed payments made by the
Authority on this Guarantee since such date.

        Section 12.     Sale of Lender Loan; Assignment of Rights.  Lender shall
                        -----------------------------------------
be permitted at any time to sell participations or other interests in the Lender
Loan without cancelling, modifying or affecting in any way this Guarantee, so 
long as Lender continues to service the Lender Loan and otherwise performs all 
of its obligations to the Authority hereunder.  In the event that Lender 
transfers all or part of the Lender Loan and does not continue to service the 
Lender Loan, then this Guarantee of such 

                                      -20-
<PAGE>
 
Lender Loan shall automatically terminate and be of no force and effect, unless
the Authority has otherwise consented in writing, which consent shall not be
unreasonably withheld. For purposes of this Section, the term "transfer" shall
include, without limitation, any assignment, assumption, sale, participation or
other conveyance of the Lender Loan, including as part of a transfer of Lender's
loan portfolio; any merger or consolidation of Lender with another entity that
is not currently an affiliate of the Lender, unless Lender is the surviving
entity; and the administration of Lender by the Federal Deposit Insurance
Corporation or the Resolution Trust Corporation or any equivalent agency,
department or successor thereto, as receiver or otherwise.

        Section 13.     No Benefit to Borrower.  In no event shall any provision
                        -----------------------
of this Guarantee be deemed to give any rights to the Borrower, this Guarantee 
being solely for the purpose of defining the respective rights of Lender and the
Authority. No payment by the Authority on this Guarantee shall be deemed to 
discharge or release the Borrower from any of its obligations under the Lender 
Loan Documents.

        Section 14.     Fees and Expenses of Authority.  Lender shall pay or 
                        ------------------------------
cause the Borrower to pay an annual guarantee fee to the Authority on the date 
of closing of the Lender Loan and on each anniversary of such date, which 
guarantee fee shall be equal to 

                                      -21-
<PAGE>
 
the product of (i) the Scheduled Amortization Loan Balance on such date
multiplied by (ii) the applicable percentage for such date determined as
hereafter set forth (the "Fee Percentage"). The Fee Percentage on the closing
date shall be one-half of one percent (.5%). The Fee Percentage shall increase
each year by 37.5 basis points, up to a maximum of one and one-quarter percent
(1.25%). Such fees shall be in addition to any application or commitment fees.

        If such annual guarantee fee is not paid within fifteen (15) days of the
date due, then the Authority shall be entitled to deliver to Tender a notice 
providing that this Guarantee may be terminated if such annual guarantee fee is
not paid according to the provisions hereunder.  Upon receipt of such notice, 
Lender will have a period of thirty (30) days either to cause payment of the 
guarantee fee by the Borrower or make such payment to the Authority itself.  
Such payment by Lender will be deemed an event of default under the Lender Loan
Documents.  In the event that such fee is not paid within such thirty (30) day 
period, the Authority may terminate this Guarantee by providing written notice 
of such termination to Lender, whereupon the Authority's obligations under this
Guarantee shall immediately be deemed terminated and of no further force or 
effect.  The Authority may not terminate this Guarantee for nonpayment of the 
guarantee fee after demand has been made on this Guarantee.

        The Borrower shall be liable to the Authority for all of the Authority's
costs and expenses relating to the Lender Loan, 

                                      -22-
<PAGE>
 
including, without limitation, reasonable attorneys' fees and expenses. It shall
be a condition to issuance of this Guarantee that all such costs and expenses of
the Authority incurred prior thereto shall have been paid in full by the
Borrower.

        Section 15.     Termination of Guarantee.  If Lender shall be in default
                        ------------------------
under the terms of this Guarantee with respect to the Lender Loan, the Authority
may notify Lender of such default in writing and Lender shall have sixty (60) 
days from the date of receipt of such written notice to cure such default; 
provided, however, that if such default cannot be reasonably cured in such sixty
(60) day period, Lender shall have an additional period of sixty (60) days to 
cure such default so long as Lender is making a diligent attempt to cure during
the initial sixty (60) day period.  The Authority shall not be required to make
any payments on this Guarantee during such 60 day periods if a default by Lender
hereunder has occurred and is continuing.  If Lender does not cure such default
within the cure period set forth above, the Authority may terminate this 
Guarantee by providing written notice to Lender to such effect.  Notwithstanding
the foregoing, the Authority shall not be entitled to terminate this Guarantee 
after the issuance thereof for any default of Lender which occurs prior to the 
issuance of the Guarantee, except in the event of fraud by Lender, or as 
provided in Section 3 hereof.

                                      -23-
<PAGE>
 
        The rights of the Authority under this Section shall be in addition to 
and not in lieu of any other rights or remedies the Authority may have upon 
breach of this Agreement by Lender.

        Section 16.     Adequacy of Bank Capitalization.  In the event that 
                        -------------------------------
Lender's tier 1 capital to assets ratio shall at any time fall below three 
percent (3%) Lender shall promptly notify the Authority.  In such event, the 
Authority may direct Lender to use its best efforts to transfer the Lender Loan
to another lender who is participating in the Guarantee program or is otherwise
acceptable to the Authority.  The Authority may terminate this Guarantee if it 
has not been so transferred within ninety (90) days of such direction by 
providing written notice thereof to Lender; provided, however that if, prior to
the termination of this Guarantee, Lender's tier 1 capital to assets ratio is
once again above three percent (3%), then the Authority shall no longer be 
entitled to direct Lender to transfer the Lender Loan or to terminate this 
Guarantee. Lender and the Authority acknowledge that federal bank regulatory 
agencies may formulate a new classification system for the capitalization of 
banks which are subject to the authority of such agencIes.  Upon implementation
of such classification system, Lender and the Authority will revise this Section
to employ such classification system in evaluating the adequacy of Lender's 
capitalization.

                17.1  This Guarantee may only be amended by an instrument in 
writing executed by Lender and the Authority.

                17.2  All of the provisions hereof shall be binding upon and 
inure to the benefit of the parties hereto and their respective successors and 
assigns, provided that any assignment by(Lender of its rights, duties or 
obligations hereunder shall be subject to terms of Section 12 hereof.

                17.3  All notices and other communications provided hereunder 
shall be in writing and mailed by registered or certified mail (return receipt 
requested), postage paid, or delivered by hand or by overnight courier or by 
telecopier or telex (with prompt confirmation by telephone), addressed to the 
respective parties hereto at their respective addresses set forth in the first 
paragraph hereof, or to such other address as shall have been furnished in 
writing to the party initiating the notice or communication.  Any notice or 
communication so addressed and mailed or delivered shall be deemed given when 
actually received by addressee.

                17.4  This Guarantee shall be governed by and construed in 
accordance with the laws of the State.

                17.5  The section headings hereof appear only as a matter of 
convenience and shall not affect the construction of this Guarantee.

        Section 18.     Requirements of the Act.  Pursuant to the terms of the 
                        -----------------------
Act, the obligations of the Authority under this Guarantee 

                                      -25-
<PAGE>
 
shall first be paid from any amounts readily available in the Connecticut Works
Guarantee Fund (as defined in the Act) before any amounts available from the
bond authorization contained in Section 32-262 of the Connecticut General
Statutes are utilized. In accordance with and subject to the Act, the faith and
credit of the State of Connecticut is pledged, pursuant to such bond
authorization and in accordance with Section 3-20 of the Connecticut General
Statutes, to provide to the Connecticut Works Guarantee Fund moneys as and when
necessary to make timely payments of all amounts required to be paid under the
terms of this Guarantee, but not in excess of the amount of bonds so authorized
by the State of Connecticut Bond Commission for such purpose less the amounts
paid by the State of Connecticut for deposit to the Connecticut Works Guarantee
Fund. NOTWITHSTANDING ANYTHING HEREIN TO THE CONTRARY, THE OBLIGATION OF THE
AUTHORITY TO MANE PAYMENTS UNDER THIS GUARANTEE SHALL BE LIMITED SOLELY TO SUCH
SOURCES AND SHALL NOT CONSTITUTE A DEBT OR LIABILITY OF THE AUTHORITY OR THE
STATE OF CONNECTICUT.

        The Lender and the Borrower each acknowledges that this Guarantee 
Certificate has been issued subject to the terms of Section 32-5a of the 
Connecticut General Statutes, as amended by Public Act 93-218 and Public Act 
93-360.  Section 32-5a:

                (i)     provides that a business organization receiving 
                financial assistance from the Authority shall not relocate 
                outside of the State of Connecticut for (A) ten (10) years after
                receiving such assistance from the Authority or (B) during the 
                term that any loan or loan guarantee constituting such financial
                assistance is outstanding, whichever is longer (such period 

                                      -26-
<PAGE>
 
                being hereafter referred to as the "Benefit Period"), unless the
                full amount of the assistance is repaid to the Authority and a 
                penalty equal to five percent (5%) of the total assistance 
                received is paid to the Authority; and

                (ii) provides that if such business organization relocates 
                within the State of Connecticut during the Benefit Period, such
                business organization shall offer employment at the new location
                to its employees from the original location if such employment 
                is available.

        Notwithstanding anything herein to the contrary, if at any time within 
the Benefit Period the Borrower relocates (as such term is defined in Section 
32-5a of the Connecticut General Statutes, and regulations related thereto, as 
the same may be amended from time to time) outside of the State of Connecticut 
(an "Out-of-State Relocation") or relocates within the State of Connecticut and
does not offer employment as provided above, then:

                (1)     such action shall constitute an immediate event of 
                default under the Lender Loan Documents and the Authority, at 
                its option, may terminate this Guarantee (if the same is still 
                in effect) by giving written notice thereof to the Lender 
                following such Out-of-State Relocation or failure to provide 
                employment, which termination shall be effective ninety (90) 
                days after the date of such notice unless the Lender makes 
                demand under this Guarantee prior to such date.  In the event 
                that the Lender makes demand under this Guarantee as a result of
                such notice and prior to the effective date of such termination,
                this Guarantee shall remain in effect with respect to the 
                Authority's and the Lender's rights and obligations following a
                demand hereon as provided in this Guarantee, except that the 
                Authority shall be deemed to have waived the Authority Cure 
                Period; and

                (2)     with respect to an Out-of-State Relocation, the Borrower
                shall immediately upon demand pay to the Authority an amount 
                equal to the full amount paid by the Authority at any time on 
                account of 

                                      -27-
<PAGE>
 
                this Guarantee, if any, and a penalty equal to five percent (5%)
                of the Guarantee Amount at the time this Guarantee was initially
                issued, such penalty to be due and payable whether or not the
                Authority has made any payment on account of this Guarantee;
                provided that the Authority's right to receive payment of the
                full amount paid on account of this Guarantee (but not its right
                to receive payment of such penalty) shall be subordinate in
                right of payment to repayment of the Lender Loan in accordance
                with the terms of this Guarantee.

        If the Borrower decides to relocate within or outside of the State of 
Connecticut at any time within the Benefit Period, the Borrower agrees to 
provide the Authority and the Lender with immediate written notice when such 
decision is made, together with such other information concerning such 
relocation as the Authority or the Lender may request.

        The Borrower's obligations pursuant to this Section 18 shall survive the
repayment of the Lender Loan and the termination of this Guarantee.

        This AMENDMENT NO. 1 (this "Amendment") to the Guarantee Agreement (the 
"Guarantee Agreement") dated as of August 22, 1994 between the CONNECTICUT

        WHEREAS, the Authority and the Bank wish to amend certain provisions of

sufficiency of which are hereby acknowledged, the Authority and the Bank agree 
as follows:

        1.      The following definitions in Section 1 of the Guarantee 
Agreement are hereby deleted in their entirety and replaced with the following:

                "Guarantee" shall mean this agreement of the Authority to

        per annum.

        2.      The second paragraph of Section 7 of the Guarantee is hereby 
amended by deleting the words "reduced in proportion to the reduction in" and 
inserting in lieu thereof "determined in part based on".

        3.      Section 8 of the Guarantee is hereby deleted in its entirety and
replaced with the following:

                Section 8.  Guarantee Amount.  The Guarantee Amount at any given
                            ----------------

        Authority under this Guarantee (other than payments pursuant to the 
        Authority's cure rights described in Section 9 which are not allocated 
        to principal on the Lender Loan), the Guarantee Amount shall be 
        immediately and automatically reduced by the amount of such payment, 
        except that the Guarantee Amount may be reinstated as provided in 
        Section 9 hereof.  Notwithstanding the foregoing, the Guarantee Amount

        to zero and this Guarantee shall not terminate until forty-five (45) 
        days after the end of such Authority Cure Period.

        4.      The first paragraph of Section 14 of the Guarantee is hereby

        and on each anniversary of such date, which guarantee fee shall be equal
        to the product of (i) the lesser of (a) the Scheduled Amortization Loan 
        Balance on such date and (b) Two Million Dollars ($2,000,000), and (ii) 
        the Fee Percentage.

        5.      All references in the Guarantee Agreement to "this Agreement," 
"herein," "hereof" and "hereunder" shall mean the Guarantee Agreement as amended
by this Amendment.

        6.      This Amendment shall be construed in accordance with and

choice of law principles).

                             EMPLOYMENT AGREEMENT
                             --------------------



Employment Agreement ("Agreement") made and entered into effective no later than
December 5, 1995 by and between Eric A. Amster (the "Employee"), and TSI
                                --------------
International Software Ltd. ("TSI"), a Delaware corporation having its principal
place of business at 45 Danbury Road, Wilton, Connecticut 06897.

WHEREAS, TSI wishes to employ the Employee and the Employee wishes to be
employed under the terms and conditions set forth herein;

NOW, THEREFORE, in consideration of the mutual covenants herein contained, the
parties hereto agree as follows:

1.  Employment and Term.
    --------------------

    1.1  TSI agrees to employ the Employee as Vice President of Sales and the
Employee agrees to render his/her full-time services to TSI for a term of one
(1) year, which term shall commence as of the date of this Agreement and
terminates at the end of the first full fiscal year thereafter, subject to the
terms of Article 6 below and annual renewal for one (1) year increments as set
forth in Paragraph 1.2.  The Employee agrees to devote his/her full business
time and the best of his/her abilities to the faithful and diligent performance
of his/her services to TSI under the direction of the President of TSI.

    1.2  Unless either party shall have given written notice of non-renewal to
the other party no fewer than thirty (30) days before the expiration of the
initial or then current renewal term, this Agreement shall automatically renew
for successive periods of one (1) year.

2.  Compensation.
    -------------

    2.1  TSI agrees to pay the Employee a salary at the annualized rate of One
Hundred Twenty-Five Thousand Dollars ($125,000.00), payable in accordance with
TSI's standard payroll practices.  This salary is for the initial term of this
Agreement, and thereafter will be as determined by the President of TSI.

    2.2  TSI will pay the Employee bonuses and commissions targeted at One
Hundred Forty-Five Thousand Dollars ($145,000.00) based upon meeting revenue
related goals (see offer letter attached).

                                                                               1
<PAGE>
 
3.  Benefits.
    ---------

    3.1  The Employee shall be entitled to participate on the same basis,
subject to the same qualifications as other TSI employees and pursuant to TSI's
then prevailing policies, in any group medical, hospitalization, or other fringe
benefit plans in effect with respect to employees of TSI in general, but not
including any group profit sharing or other profit-based incentive program.

    3.2  The Employee shall be entitled to the same number of paid holidays per
year as set forth by TSI for its employees in general plus twenty (20) paid
vacation days to be scheduled by the mutual agreement of the parties.

4.  Stock Options.  As soon as is practical after signing of this Agreement by
    -------------
both parties, but no later than three (3) months after signing, TSI shall issue
24,000 options to the Employee as described in the TSI Stock Option Plan
attached hereto as Appendix A.  There will be a change to Section 12.01 of the
Stock Option Plan as we have discussed.

5.  Employment Guidelines.  The Employee agrees to at all times be bound by and
    ---------------------
adhere to the Conditions of Employment attached hereto as Appendix B and
incorporated herein by reference, and to use his/her best efforts to protect the
proprietary and confidential materials and information of TSI and of TSI's
clients, including valuable trade secrets.

6.  Termination.
    ------------

    6.1  This Agreement shall terminate and all payments due hereunder shall
cease, except to the extent accrued, upon death of the Employee, without further
act of TSI. If, however, at the time of Employee's death, Employee is receiving
severance compensation per the terms of Paragraph 1.3, unpaid severance will be
paid to the Employee's estate in a lump sum.

    6.2  TSI shall have the right to terminate this Agreement and any payments
due hereunder upon prior written notice to the Employee if a licensed physician
employed by the Board of Directors of TSI shall determine that the Employee, by
reason of physical or mental disability (excluding infrequent and temporary
absences due to ordinary transitory illness) shall be unable to perform the
services required of him/her hereunder for more than three (3) consecutive
months or an aggregate of six (6) months during any twelve (12) month period,
except as otherwise provided by law.

                                                                               2
<PAGE>
 
    6.3  TSI shall have the right to terminate this Agreement, without further
compensation, upon a breach of failure to fulfill and perform obligations and
duties hereunder, which condition, breach or failure Employee shall fail to
remedy within ten (10) days after written demand from TSI.  Further, TSI shall
have the right to terminate this Agreement, without further compensation, if,
(i) in the opinion of the Board of Directors of TSI, the Employee is guilty of
insubordination, fraud, dishonesty, misconduct or negligence in connection with
the performance of duties hereunder, (ii) the Employee is convicted of a felony
or of a crime involving moral turpitude, (iii) the Employee causes TSI
disrepute, or (iv) otherwise for good cause.

    6.4  TSI shall have the right to terminate this Agreement, for convenience,
at the discretion of the Board of Directors. If such termination occurs, the
Employee will receive a severance compensation of six (6) months of salary, as
outlined in paragraph 2.1, payable in accordance with TSI's standard payroll
practices, and six (6) months of continuance of eligible benefits as outlined in
Paragraph 3.1, and shall be entitled to no other payment or benefit from TSI.

    6.5  Upon termination or expiration of this Agreement, irrespective of the
reason therefor, the Employee shall promptly turn over to TSI all proprietary
and confidential materials of the kind referred to in Section 5 and all tangible
forms of the Employee's work product (including work files) without retaining
any copies or duplicates thereof, except as to which TSI may in writing give
permission.

7.  Negative Covenant.
    ------------------

    7.1  The Employee agrees that during the term of this Agreement (including
any renewal terms hereunder) and for a period of one (1) year following the
termination of this Agreement, he/she will not, directly or indirectly, own,
operate, manage, join, control, or participate in the ownership, management,
operation or control of, or be connected with as a partner, stockholder,
director, officer, agent, employee, or consultant, any business, firm, or
corporation in any capacity that involves the development, production or sale of
any product that is directly competitive with TSI in the territories TSI serves;
provided, however, that nothing in this Section 7.1 shall bar the acquisition of
any publicly traded securities which do not confer upon the Employee the right
to control or influence the policy of the issuer.

    7.2  The Employee further agrees that for a period of one (1) year following
the termination of this Agreement, he/she will not, without the prior written
consent of TSI, (a) solicit for employment any of the staff of TSI or of TSI's
customers, or (b) solicit the business of TSI's customers for products that are
directly competitive to TSI products.

                                                                               3
<PAGE>
 
    7.3  In the event a court of competent jurisdiction finds any part of this
Article 7 unenforceable, the parties agree that such finding shall not effect or
render invalid or unenforceable any other provision of this Article.  The
parties further agree to execute any amendments necessary to accomplish the
intent of this Article to the fullest extent possible under the law.

8.  Remedies.  The parties hereto recognize that, in the event of any breach by
    --------
the Employee of the provisions of Sections, 5, 6 or 7 hereof, damages may be
difficult, if not impossible, to ascertain and it is therefore agreed that TSI,
in addition to and without limiting any other remedy it might have under this
Employment Agreement, or at law or in equity, shall be entitled to an injunction
against the Employee issued by any court of competent jurisdiction enjoining any
such breach.  The Employee agrees to reimburse TSI for all out-of-pocket costs
and expenses, including reasonable attorney's fees, incurred by TSI by reason of
any such breach; provided, however, that if a court of competent jurisdiction in
any action wherein TSI is the claimant with respect to such breach shall
determine that no such breach occurred or is likely, and if any appeal therefor
be taken by TSI where such determination shall be fully and finally upheld, TSI
shall reimburse the Employee for all out-of-pocket costs and expenses, including
reasonable attorney's fees, incurred by the Employee by reason of such action
and any appeal.

                                                                               4
<PAGE>
 
9.  Representation and Warranty.  Employee represents and warrants that he/she
    ---------------------------
is not now and was not on the date of commencement of this Agreement, a party to
any Agreement, contract or understanding, whether of employment or otherwise,
which would in any way restrict or prohibit him/her from undertaking or
performing employment in accordance with the terms and conditions of this
Agreement.

10. Miscellaneous.
    --------------

    10.1  Should any provision or part of this Employment Agreement be declared
void or unenforceable by any court or administrative body of competent
jurisdiction, such provisions or part shall be deemed severable and, without
further action by the parties to this Agreement, shall be severed from the
remainder of this Agreement which shall continue in all respects valid and
enforceable.

    10.2  Any notices or communications hereunder shall be in writing and shall
be personally delivered or sent by registered or certified mail to the addresses
specified herein or, after proper notice, to such addresses as the parties may
specify.

    10.3  This Agreement shall be binding upon and inure to the benefit of TSI,
its successors or assigns, or any corporation which acquires all or
substantially all of its assets. This Agreement is personal as to the Employee
and shall not be assignable by the Employee.

    10.4  This Agreement constitutes the entire understanding of the parties
hereto with respect to the Employee's employment and his/her compensation
therefor and supersedes any prior Agreements and understandings between the
parties concerning employment or compensation.

    10.5  This Agreement shall be governed by and construed under the laws of
the State of Connecticut.

                                                                               5
