                                  THE COMPANY
 
  Enterprise is a healthcare information services company that develops,
markets, installs and services an integrated suite of application software
products that assist healthcare providers in managing their operations. These
resource management systems focus on cost containment and address a broad range
of non-clinical management needs, including materials management, operating
room logistics, patient and staff scheduling and financial management. The
Company's information systems operate on personal computer networks and make
extensive use of electronic data interchange, enabling its customers to
redesign their resource management functions to enhance efficiency and
productivity.
 
  In recent years, governmental and market-driven reform initiatives have
produced significant pressures on healthcare providers to control costs. In
order to manage the economic risk of healthcare delivery, providers are being
forced to change the way they operate and are increasingly focused on measuring
and controlling the cost of delivering care. To date, there has been a lack of
emphasis on integrated information systems that effectively manage operational
costs, which the Company believes constitute a majority of providers' overall
costs. Without the necessary information, it has been difficult for healthcare
managers to allocate efficiently their resources--people, supplies, facilities,
equipment and services--or to understand their costs.
 
  Enterprise has developed information systems that address the operational
aspects of healthcare delivery. The Company offers an integrated suite of
resource management systems that enable healthcare providers to (i) improve
productivity through the redesign and automation of operational processes and
(ii) obtain the information necessary to measure and control costs. The
Company's current product offerings address materials management, operating
room logistics, organization-wide patient and staff scheduling and financial
management, areas which the Company believes offer significant opportunities
for productivity improvement and cost savings. The Company's products are
modular in design, share a common database, and may be used independently or
bundled together in order to provide an integrated resource management system
solution.
 
  The Company's business strategy is to strengthen its existing product lines
and to expand into additional resource management areas. The Company believes a
significant opportunity exists to penetrate further the market of approximately
2,900 large acute care hospitals and 3,100 small hospitals in the United States
and Canada. Most of the Company's existing customers do not currently use the
Company's entire product line. The Company believes that its high customer
retention rate provides an opportunity to sell additional components of its
product suite to its existing customers, which include approximately 1,000
acute care hospitals, of which approximately 270 were added as customers when
the Company acquired the Matkon materials management division of Continental
Healthcare Systems, Inc. in May 1996 (the "Matkon
 
                                       3
<PAGE>
 
Acquisition"). Of those customers (other than customers of the Matkon division)
which have purchased the Company's current products since January 1, 1991,
approximately 97% remained customers at July 1, 1996. The Company also intends
to expand its limited presence in alternate site markets, including outpatient
clinics, ambulatory surgery centers and specialty laboratories. In addition,
the Company has entered into joint marketing agreements with group purchasing
organizations and hospital management organizations, which typically provide
for the Company's products to be recommended on a preferred or exclusive basis.
The Company intends to pursue similar agreements, joint ventures or other
arrangements (which may include investments by the Company) with certain
healthcare information system developers and resellers and certain medical
product suppliers.
 
  The Company was organized under the laws of the State of Illinois in 1981 and
was reincorporated in the State of Delaware in October 1995. The Company's
principal executive offices are located at 1400 South Wolf Road, Wheeling,
Illinois 60090-6524. The Company's telephone number is (847) 537-4800.
 
                              RECENT DEVELOPMENTS
 
  On January 2, 1996, the Company entered into a distribution agreement with
Total Care Technologies, Inc. to distribute a staff scheduling software product
known as ESP for Windows. The agreement provides the Company with exclusive
territorial rights in the United States healthcare market for an initial term
of 26 months with the option to renew thereafter.
 
  On March 22, 1996, the Company entered into a license agreement with
FlexiInternational Software, Inc. that allows the Company to incorporate the
FLEXI general ledger and accounts payable applications into the Company's
products for distribution in the United States healthcare market for an initial
term of four years with the option to renew thereafter.
 
  On May 28, 1996, the Company completed the Matkon Acquisition for a cash
purchase price of approximately $13.9 million. The Matkon division develops,
markets, installs and services a line of hospital materials management software
products which primarily run on a UNIX platform. The Company recorded charges
of $8,453,000 in the quarter ended June 30, 1996 for acquired in-process
technology in connection with the Matkon Acquisition. See "Recent
Developments."

                                 RISK FACTORS
 
  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 shares of Common Stock offered hereby. 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.
 
ABILITY TO DEVELOP NEW SOFTWARE PRODUCTS; RAPID TECHNOLOGICAL CHANGE
 
  The healthcare information systems market is characterized by rapid
technological change, changing customer needs, frequent new software product
introductions and evolving industry standards. Historically, the Company has
derived substantially all of its revenue from three products: NOVA (materials
management), ORBIT (operating room logistics) and TITAN (accounts payable
management). The Company believes that as the market for these products
matures, its future success will depend upon its ability to enhance current
products and to develop and introduce new software products that keep pace
with technological developments and emerging industry standards and that
address the increasingly sophisticated needs of its customers. In addition,
the introduction of competing products embodying new technologies and the
emergence of new industry standards could render the Company's existing
products obsolete and unmarketable. Accordingly, the Company anticipates that
significant amounts of future revenue will be derived from products and
product enhancements which either do not exist today or have not been sold in
large enough quantities to ensure market acceptance. There can be no assurance
that the Company will not experience difficulties that could delay or prevent
the successful development and introduction of product enhancements or new
products, or that such enhancements or new products will adequately meet the
requirements of the marketplace or achieve market acceptance. If the Company
is unable to develop and introduce product enhancements and new products in a
timely and cost-effective manner in response to changing market conditions or
customer requirements, the Company's business, operating results and financial
condition will be materially and adversely affected. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations."
 
PRODUCT CONVERSIONS TO WINDOWS
 
  Currently, the Company is converting its remaining DOS-based products, which
include NOVA, ORBIT and TITAN, to a Windows platform. As a result of the
complexities involved in such a conversion, the new Windows versions will
require significant development and testing periods before they achieve
marketability. There can be no assurance that the Windows versions will be
completed before demand for the DOS versions slows or before the Company's
competitors are able to develop functionally equivalent products on a Windows
platform. Further, certain potential customers may delay purchasing decisions
until Windows versions of the Company's products are available. There can be
no assurance that the Company will not experience difficulties that could
delay or prevent the successful and timely development, introduction and
marketing of the new Windows versions of its products, or that such versions
will adequately meet the requirements of the marketplace and achieve market
acceptance. In addition, the conversions will divert resources away from
developing or enhancing other products. The occurrence of any of these
potential product conversion problems could have a material adverse effect on
the Company's business, operating results and financial condition. See
"Business--Products."
 
NEW PRODUCT ACCEPTANCE
 
  The Company may find that the market does not fully accept certain of its
products in their current forms and may be slow to adopt new information
systems technology. For example, the Company's TouchScan point-of-use resource
management product requires a healthcare organization to re-engineer its
operations in order to realize the full economic benefit from the product. As
a result, the volume of sales of the TouchScan product has been substantially
lower than the Company originally forecasted. If TouchScan does not achieve a
greater degree of market acceptance, the Company's growth in future revenues
may be materially and adversely affected.
 
                                       6
<PAGE>
 
ACQUISITIONS
 
  The Company's growth strategy may be implemented, in part, through
acquisitions of products, technologies and businesses. The success of any such
acquisition will depend on many factors, including the Company's ability to
identify suitable acquisition candidates, the purchase price, the availability
and terms of financing, and management's ability to integrate effectively the
acquired products, technologies or businesses into the Company's operations.
Significant competition for acquisition opportunities exists in the industry,
which may significantly increase the costs of potential acquisitions. Further,
acquisitions may involve a number of special risks, including, failure to
retain key acquired personnel, unanticipated events or circumstances, legal
liabilities and amortization of acquired intangible assets, some or all of
which could have a material adverse effect on the Company's business,
operating results and financial condition. In addition, the Company competes
for acquisition opportunities with other companies that have significantly
greater financial and management resources and experience in acquiring
products, technologies and businesses. There can be no assurance that the
Company will be able to finance or integrate successfully any acquired
products, technologies or businesses, and their identification, acquisition
and integration may cause a diversion of management time and resources. The
Company cannot assure that a given acquisition will not materially and
adversely affect the Company's business, operating results and financial
condition.
 
  The Company recorded charges of $8,453,000 for acquired in-process
technology in connection with the Matkon Acquisition, which reduced the
Company's operating and net income for the six months ended June 30, 1996. The
Company may incur similar charges in connection with future acquisitions. See
"Recent Developments" and "Management's Discussion and Analysis of Financial
Condition and Results of Operations."
 
VARIABLE QUARTERLY OPERATING RESULTS; SEASONALITY
 
  The Company's quarterly revenues and operating results have varied
significantly in the past and are likely to vary substantially from quarter to
quarter in the future. Furthermore, the Company has experienced a seasonal
pattern in its operating results, with a greater proportion of the Company's
revenue and operating profitability occurring in the second half of the year.
Accordingly, results of operations for any particular quarter may not be
indicative of results of operations for future periods. Quarterly revenues and
operating results may fluctuate as a result of a variety of factors including:
the Company's sales cycle; demand for the Company's products; the size and
timing of significant orders; competitive conditions in the industry; the
ability of the Company to develop, introduce and market new products and new
releases on a timely basis; deferrals of customer orders in anticipation of
new products or new releases; delay or deferral of customer implementations of
the Company's products; changes in customer budgets; and general economic
factors. A significant portion of the Company's expenses are relatively fixed,
and the amount and timing of increases in such expenses are based in large
part on the Company's expectations for future revenues. If revenues are below
expectations in any given quarter, the adverse effect may be magnified by the
Company's inability to adjust spending quickly enough to compensate for the
revenue shortfall. Accordingly, even a small variation from expected revenues
could have a material adverse effect on the Company's results of operations
for a given quarter. The Company plans to increase expenditures in order to
fund a larger direct sales and marketing staff, greater levels of research and
development, and development of new distribution and resale channels. To the
extent such expenses precede or are not subsequently followed by increased
revenues, the Company's operating results would be materially and adversely
affected.
 
  The timing and amount of the Company's revenues are subject to a number of
factors that make estimation of operating results prior to the end of a
quarter extremely uncertain. In addition, certain large contracts may, in the
future, constitute a substantial portion of the operating profits for a
quarter. Contract signing may be delayed for a number of reasons outside of
the control of the Company, including customers' budgetary constraints and
internal authorization reviews. In addition, the Company's ability to complete
installation of its systems and recognize revenues is dependent on certain
factors outside the control of the Company, including the customer's ability
to allocate its internal resources to the installation process.
 
                                       7
<PAGE>
 
Consequently, the Company's business or operating results for a particular
quarter could be materially and adversely affected. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations."
 
COMPETITION
 
  The market for healthcare information systems is intensely competitive. The
competitive factors affecting the market for the Company's software and
services include: vendor and product reputation, availability of products on
preferred computer and communications platforms, scalability, integration with
other applications, functionality and features, ease of use, quality of
support, documentation and training, product quality, product innovation,
price and the effectiveness of marketing and sales efforts. The relative
importance of each of these factors depends upon the market segment. Certain
of the Company's competitors have significantly greater financial, technical,
research and development and marketing resources. As a result, they may be
able to respond more quickly to new or emerging technologies and changes in
customer requirements, or to devote greater resources to the development,
promotion, sale and support of their products than the Company. In addition,
consolidation in the healthcare information systems industry may permit the
Company's competitors to have access to increased financial and administrative
resources and greater technological capabilities and to realize other
operational efficiencies and competitive advantages. Moreover, some purchasers
may prefer to buy computer systems from a single source provider. Because the
Company focuses exclusively on healthcare resource management systems (as
opposed to clinical or billing systems), it cannot serve as the sole source of
computer software for healthcare organizations. The Company cannot assure that
it will be able to continue to compete effectively in this environment, that
competition will not intensify or that future competition will not have a
material adverse effect on the Company's business, operating results or
financial condition. See "Business--Competition."
 
UNCERTAINTY AND CONSOLIDATION IN HEALTHCARE INDUSTRY
 
  The healthcare industry is subject to changing political, economic and
regulatory influences that may affect the procurement practices and operation
of healthcare providers. Many federal and state legislators have announced
that they intend to propose programs to reform the United States healthcare
system at both the federal and state level. These programs may contain
proposals to increase governmental involvement in healthcare, lower
reimbursement rates and otherwise change the environment in which providers
operate. Healthcare providers may react to these proposals and the uncertainty
surrounding such proposals by curtailing or deferring investments, including
investments in the Company's products and services.
 
  In response to this environment, many healthcare providers are consolidating
to create larger healthcare delivery organizations. This consolidation reduces
the number of potential customers for the Company's products, and the
increased bargaining power of these organizations could lead to reductions in
the amounts paid for the Company's products. Further, because the Company's
product offerings have expanded into a more extensive package of integrated
products, purchases of the Company's products increasingly require approval by
a customer's executive officers as opposed to departmental managers by whom
the Company is better known. The impact of these developments in the
healthcare industry is difficult to predict and could have a material adverse
effect on the Company's business, operating results and financial condition.
See "Business--Government Regulation."
 
INABILITY TO EXPAND INTO NEW MARKETS
 
  To date, the Company's products have been purchased primarily by acute care
hospitals. However, healthcare services are increasingly being provided at
sites other than hospitals, such as outpatient clinics, ambulatory surgery
centers and specialty laboratories. The Company intends to increase its
limited presence in these alternate site markets. Because the Company has
limited experience in non-hospital markets, it may find that significant
modifications to its products are necessary before they become useful to a
customer or that pricing may have to be adjusted downward. The Company's
business, operating results and financial condition may be materially and
adversely affected if such alternate site markets are not receptive to the
Company's products.

DEPENDENCE ON PROPRIETARY TECHNOLOGY; RISKS OF INFRINGEMENT
 
  The Company depends significantly upon proprietary technology. The Company
relies on a combination of copyright, trade secret and trademark laws,
confidentiality procedures and contractual provisions to protect its
proprietary rights. The Company seeks to protect its software, documentation
and other written materials under trade secret and copyright laws, which
afford only limited protection. Despite the Company's efforts to protect its
proprietary rights, unauthorized parties may attempt to copy aspects of the
Company's products or to obtain and use information that the Company regards
as proprietary. Policing unauthorized use of the Company's products is
difficult, and although the Company is unable to determine the extent to which
piracy of its software products exists, software piracy is a potential
problem. In addition, the laws of some foreign countries in which the Company
sells or may in the future sell its products do not protect the Company's
proprietary rights to as great an extent as do the laws of the United States.
The Company cannot assure that its protective measures for proprietary rights
will be adequate or that the Company's competitors will not independently
develop similar or superior technology, duplicate the Company's products or
circumvent its intellectual property rights.
 
  Substantial litigation regarding intellectual property rights exists in the
software industry, and the Company expects that software products may be
increasingly subject to third-party infringement claims as the number of
products and competitors in the Company's industry segment grows and the
functionality of products overlaps. Although the Company has never received a
claim that it is infringing third parties' intellectual property rights, there
can be no assurance that third parties will not in the future claim
infringement by the Company with respect to current or future products,
trademarks or other proprietary rights. Any such claims, regardless of their
merit, could be time consuming, result in costly litigation, delay or prevent
product shipments or require the Company to enter into costly royalty or
licensing agreements. Such royalty or licensing agreements, if required, may
not be available on terms acceptable to the Company or at all, which could
have a material adverse effect on the Company's business, operating results
and financial condition. See "Business--Proprietary Rights."
 
PRODUCT LIABILITY
 
  The software products offered by the Company may contain undetected errors
or failures when first introduced or as new versions are released. Errors or
failures that are not detected until after the commencement of commercial
shipments of a product could result in loss of or delay in market acceptance
of the product and in claims against the Company. Any of these factors could
have a material adverse effect on the Company's business, operating results
and financial condition. See "Business--Strategy," "--Products" and "--Product
Development and Technology."
 
DEPENDENCE ON KEY PERSONNEL
 
  The Company depends to a significant extent on certain key personnel. In
addition, the Company believes that its growth and success will depend on its
ability to attract and retain qualified management, technical, sales and
marketing personnel. Competition for such personnel is intense. The loss of
the services of one or more of the Company's key employees or the Company's
inability to attract and retain qualified personnel could have a material
adverse effect on the Company's business, operating results and financial
condition. While the Company does have employment contracts with all members
of its executive management team, and with certain key product and software
development employees, these contracts do not guarantee that these individuals
will continue their employment with the Company. The Company maintains "key
man" life insurance of $1,000,000 on the life of Glen E. Tullman, Chief
Executive Officer.
 
CONTROL BY OFFICERS AND DIRECTORS
 
  Upon completion of this offering, Thomas R. Pirelli, a Director and a
founder of the Company, will beneficially own an aggregate of 1,586,630 shares
of Common Stock, representing approximately 20% of the
 
                                       9
<PAGE>
 
outstanding Common Stock assuming 600,000 shares are sold by the Company in
this offering. The Company's other Directors, executive officers and principal
stockholders, including its 401(k) Plan, and their affiliates will
beneficially own approximately 25% of the outstanding Common Stock assuming
600,000 shares are sold by the Company in this offering. Consequently, these
stockholders, acting together, will be able to control all matters requiring
stockholder approval, including the election of directors and approval of
significant corporate transactions. Such concentration of ownership may have
the effect of delaying or preventing a change in control of the Company. See
"Principal Stockholders" and "Description of Capital Stock--Antitakeover
Effects of Provisions of the Certificate of Incorporation, By-Laws and
Delaware Law."
 
UNALLOCATED PROCEEDS OF OFFERING
 
  None of the anticipated net proceeds of this offering have been designated
for specific uses. Therefore, the Board of Directors of the Company will have
broad discretion with respect to the use of the net proceeds of this offering.
See "Use of Proceeds."
 
POSSIBLE VOLATILITY OF STOCK PRICE
 
  Since the Company's initial public offering in October 1995, the market
price for the Common Stock has fluctuated substantially. The market price of
the Common Stock may continue to experience significant fluctuations in
response to quarter-to-quarter variations in the Company's operating results,
announcements of technological innovations or new products by the Company or
its competitors, governmental regulatory actions, general trends in the
industry and other events. In addition, the stock market in recent years has
experienced extreme price and volume fluctuations that have particularly
affected the market prices of many technology companies and that have often
been unrelated or disproportionate to the operational performance of these
companies. These fluctuations, as well as general economic and market
conditions, may materially and adversely affect the market price of the Common
Stock. See "Price Range of Common Stock."
 
SHARES ELIGIBLE FOR FUTURE SALE
 
  Sales of a substantial number of shares of Common Stock in the public market
following this offering could adversely affect the market price for the Common
Stock. Upon completion of this offering, the Company will have 8,119,581
shares of Common Stock outstanding, assuming no exercise of options after
September 1, 1996. Substantially all of these shares will be freely tradeable
without restriction under the Securities Act of 1933, as amended (the
"Securities Act"), or may currently be sold in accordance with Rule 144 under
the Securities Act ("Rule 144"). In addition, the Company has registered on a
registration statement on Form S-8 a total of 1,114,846 shares of Common Stock
reserved for issuance under the Company's Long-Term Incentive Compensation
Plan, of which options for 181,882 shares have been exercised as of September
1, 1996. The remaining 932,964 shares, when and if issued, would be freely
tradeable (unless acquired by an affiliate of the Company, in which case they
would be subject to volume and other limitations under Rule 144). The
Directors and executive officers of the Company and the Company's 401(k) Plan,
beneficially holding an aggregate of 2,784,169 shares of Common Stock as of
September 1, 1996, have entered into lock-up agreements pursuant to which such
stockholders have agreed not to sell or otherwise dispose of any shares of
Common Stock for a period of 90 days after the date of this Prospectus without
the prior written consent of Robertson, Stephens & Company LLC ("Robertson,
Stephens & Company"). However, Robertson, Stephens & Company may, in its sole
discretion and at any time without notice, release all or any portion of the
securities subject to lock-up agreements. Upon expiration or early termination
of the lock-up period, these shares will be eligible for immediate sale,
subject in certain cases to volume and other limitations under Rule 144. See
"Shares Eligible for Future Sale" and "Plan of Distribution."
 
EFFECT OF CERTAIN CHARTER PROVISIONS; ANTITAKEOVER EFFECTS OF CERTIFICATE OF
INCORPORATION, BY-LAWS AND DELAWARE LAW
 
  The Company's Board of Directors has the authority to issue shares of
preferred stock and to fix the rights, preferences, privileges and
restrictions, including voting rights, of those shares without any further
vote
 
                                      10
<PAGE>
 
or action by the stockholders. The rights of the holders of Common Stock will
be subject to, and may be adversely affected by, the rights of the holders of
any preferred stock that may be issued in the future. The issuance of
preferred stock could have the effect of delaying, deferring or preventing a
change in control of the Company. In addition, certain provisions of the
Company's Certificate of Incorporation and By-Laws and of Delaware law could
have the effect of delaying, deterring or preventing a change in control of
the Company. See "Description of Capital Stock--Preferred Stock" and "--
Antitakeover Effects of Provisions of the Certificate of Incorporation, By-
Laws and Delaware Law."
 
HOLDING COMPANY STRUCTURE
 
  The Company derives substantially all of its operating income and cash flows
from its subsidiary. The Company relies on dividends and other distributions
from its subsidiary to generate the funds necessary to meet its obligations.
The ability of the Company's subsidiary to make such distributions is subject
to, among other things, applicable state laws and the terms of the
subsidiary's credit facility. Claims of creditors of the Company's subsidiary,
including trade creditors, will generally have priority as to the assets of
such subsidiary over the claims of the Company. See "Description of Capital
Stock--Recapitalization."

                              RECENT DEVELOPMENTS
 
  On January 2, 1996, the Company entered into a distribution agreement with
Total Care Technologies, Inc. ("TCT") to distribute a staff scheduling
software product known as ESP for Windows ("ESP"). The agreement provides the
Company with exclusive territorial rights in the United States healthcare
market for an initial term of 26 months with the option to renew thereafter.
ESP is a Windows-based client/server product that assists users in managing
the complex staffing issues for numerous clinical and operational areas,
including nursing, dietary/food service, housekeeping, clinical technician
services, surgical services and physical and occupational therapy. The
Company's minimum royalty commitment to TCT over the initial 26-month term of
the agreement is approximately $1.2 million. As of September 27, 1996, the
Company has licensed eleven copies of TCT's staff scheduling software.
 
  On March 22, 1996, the Company entered into a license agreement with
FlexiInternational Software, Inc. ("FLEXI") that allows the Company to
incorporate the FLEXI general ledger and accounts payable applications into
the Company's products for distribution in the United States healthcare market
for an initial term of four years with the option to renew thereafter. The
Company has an exclusive right to sell the FLEXI applications in the United
States upon meeting certain sales levels. FLEXI products are Windows-based
client/server products that operate in both the Windows NT and UNIX
environments. The Company's minimum royalty commitment to FLEXI over the
initial four year term of the agreement is approximately $2.0 million.
 
  On May 28, 1996, the Company completed the Matkon Acquisition for a cash
purchase price of approximately $13.9 million. The Matkon division develops,
markets, installs and services a line of hospital materials management
software products which primarily run on a UNIX platform. The Matkon division
has an installed base of approximately 270 acute care hospitals. The Company
recorded charges of $8,453,000 in the quarter ended June 30, 1996 for acquired
in-process technology in connection with the Matkon Acquisition. See
"Consolidated Pro Forma Financial Information" and "Selected Financial Data."

                                USE OF PROCEEDS
 
  The net proceeds from the sale of the 600,000 shares of Common Stock offered
hereby are estimated to be approximately $13,485,190, assuming a public
offering price of $24.3125 per share and after deducting estimated fees of the
Placement Agents and estimated offering expenses. The Company expects to use
the net proceeds of this offering for general corporate purposes. A portion of
the net proceeds may also be used for acquisitions of, or joint ventures with
respect to, additional businesses, products and technologies. However, the
Company has no agreements or commitments with respect to any such
transactions. Pending such uses, the net proceeds of this offering will be
invested in short-term, investment-grade, interest-bearing securities.
 
  There can be no assurance that the Company will be successful in selling any
or all of the shares of Common Stock offered hereby. The Company has not fixed
a minimum number of shares of Common Stock to be sold pursuant to this
offering. Therefore, the Company may sell less than all of the shares of
Common Stock offered hereby, which may significantly reduce the amount of
proceeds received by the Company.

                                DIVIDEND POLICY
 
  The Company has never paid any cash dividends on its capital stock. The
Company currently anticipates that all of its earnings will be retained for
development of the Company's business, and does not anticipate paying any cash
dividends (other than intercompany dividends) in the foreseeable future.

                 CONSOLIDATED PRO FORMA FINANCIAL INFORMATION
 
  The accompanying consolidated pro forma financial information gives effect
to the Matkon Acquisition. The consolidated pro forma statement of operations
for the fiscal year ended December 31, 1995 combines the audited consolidated
statement of operations of the Company for the fiscal year ended December 31,
1995 with the audited statement of revenues and expenses of the Matkon
division for the twelve-month period ended November 30, 1995 as if the Matkon
Acquisition had occurred at January 1, 1995. The pro forma statement of
operations for the six-month period ended June 30, 1996 combines the unaudited
consolidated pro forma statement of operations of the Company for the six-
month period ended June 30, 1996 with the unaudited statement of revenues and
expenses of the Matkon division for the six-month period ended May 31, 1996 as
if the Matkon Acquisition had occurred at January 1, 1995. The transaction has
been accounted for as a purchase and appropriate adjustments have been made to
the consolidated pro forma statements of operations to reflect the transaction
at the beginning of the respective periods combined. The consolidated pro
forma financial information presented below is not necessarily indicative of
the operating results which would have been achieved had the Matkon
Acquisition occurred at the beginning of the periods presented or of results
to be achieved in the future.

1. On May 28, 1996, the Company completed the Matkon Acquisition for a cash
   purchase price of approximately $13.9 million. The Matkon Acquisition has
   been reflected as though such transaction occurred on January 1, 1995. The
   expected purchase price allocation includes approximately $8.4 million of
   acquired in-process technology and $1.7 million of purchased software. The
   allocation of purchase price represents an estimate of the fair values of
   assets acquired and liabilities assumed including estimated professional
   fees and other acquisition expenses expected to be incurred. The allocation
   is subject to change and is not necessarily indicative of the ultimate
   purchase price allocation. The charge for the acquired in-process
   technology of approximately $8.4 million is not reflected in the
   Consolidated Pro Forma Statement of Operations for the year ended December
   31, 1995. Such amount is a charge to earnings in the period of acquisition.
2. The consolidated pro forma financial information is based on the following
   assumptions and adjustments:
  a. To conform Matkon's policy of capitalizing certain software development
     expenses to the Company's method of software capitalization.
  b. To reflect the amortization of the excess of cost over net assets
     acquired and other intangible assets.
  c. To reduce interest income related to cash payments made for the
     acquisition.
  d. To reflect the net income tax benefit relating to the adjustments
     discussed above using an effective tax rate of 40%.
3. The Company's consolidated statement of operations for the six months ended
   June 30, 1996 includes revenues and net income of $797,000 and $199,000,
   respectively, related to the results of the operations of the Matkon
   division during the period from May 29, 1996 to June 30, 1996.

                     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.
 
OVERVIEW
 
  Enterprise was founded in 1981. The Company develops, markets, installs and
services an integrated suite of application software products that assist
healthcare providers in managing their operations. The Company derives its
revenues from software licenses, installation services, ongoing support,
maintenance and enhancement services, product education, consulting and the
sale of computer hardware. While the Company's customers currently consist
primarily of large acute care hospitals (hospitals with 150 or more beds), it
has increased its efforts to penetrate other healthcare provider markets, in
particular, small hospitals (hospitals with less than 150 beds) and alternate
site facilities such as outpatient clinics, ambulatory surgery centers and
specialty laboratories.
 
  The selling cycle for the Company's software products has generally ranged
from six to twelve months, culminating with the signing of a license
agreement. These agreements provide for up-front fees for each of a system's
components, including the software license, installation services, initial
product education and hardware (if required), as well as annual fees for
ongoing support, maintenance and enhancements. Payment terms for up-front fees
generally provide for remittances upon contract signing, software load,
initial operational use and post-installation review. The agreements typically
provide for a minimum of one year of support, maintenance and enhancement
fees, renewable annually. Generally, fees for support and maintenance are
billed monthly, while enhancement fees are billed annually. The Company also
offers continuing product education and on-site consulting services.
 
  Software revenues consist of software license fees. Services revenues
consist of (i) up-front fees for software installation and initial product
education, (ii) annual fees for ongoing support, maintenance and enhancements
and (iii) fees for continuing product education and consulting services.
Revenues from software licensing and installation services are recognized as
the installation services are performed. Ongoing support, maintenance and
enhancement revenue is recognized ratably over the time periods covered by the
service agreements. The Company recognizes education and consulting revenue as
the services are performed.

Revenues
 
  The Company derives its revenues from software licenses, installation
services, ongoing support, maintenance and enhancement services, product
education, consulting and the sale of computer hardware. Total revenues for
the first half of 1996 were $21,043,000, an increase of $6,603,000 or 46%, as
compared to $14,440,000 for the same period in 1995. Total revenues from all
sources for 1995 were $33,248,000, an increase of $8,536,000 or 35% from 1994
total revenues of $24,712,000. Total revenues in 1994 increased $4,285,000 or
21% over 1993 revenues of $20,427,000.
 
  Software. Software revenues for the first half of 1996 increased $2,872,000,
or 41%, as compared to the same period of 1995. In 1995, software revenues
were $16,104,000, a 37% increase over 1994. From 1993 to 1994, software
revenues increased 30% from $9,065,000 to $11,762,000. The increases are
primarily attributable to expansion of the Company's sales force and marketing
efforts.
 
  Services. Services revenues for the first half of 1996 increased $3,214,000,
or 44%, as compared to the first half of 1995. Services revenues in 1995
increased 34% over 1994 to $16,498,000, and 1994 services revenues of
$12,343,000 represented an increase of 15% over 1993 services revenues. The
increase in services revenues is related to the increase in software revenues
coupled with an increase in consulting services revenues and growth in
recurring support fees.
 
  Hardware. Hardware revenues for the first half of 1996 increased $517,000 as
compared to the first half of 1995. Hardware revenues in 1995 increased
$39,000 or 6% over 1994 to $646,000. From 1993 to 1994, hardware revenues
declined $102,000. Prior to 1995, hardware revenues had declined over time as
customers had increasingly elected to purchase personal computer equipment
from other sources. The increases in hardware revenues in 1995 and the first
six months of 1996 are principally attributable to sales of TouchScan, which
was introduced in 1995.

Costs and Expenses
 
  Software Development. Software development expenses for the first half of
1996 increased $667,000, or 20%, as compared to the first half of 1995.
Software development expenses increased to $7,536,000 in 1995 from $6,377,000
in 1994 and $4,237,000 in 1993. The increases in these expenses are primarily
related to development work on new releases of each of the Company's product
lines and the ongoing conversion of its DOS-based products to a Windows-based
platform. For the first six months of 1996, software development expenses
decreased as a percentage of total revenues from the year earlier period,
however, because a larger percentage of development effort was related to new
products, rather than enhancement of existing products, more software
development expenditures were capitalized in that period.
 
  The Company capitalized $666,000 and $338,000 of software development costs,
net of related amortization expense, for the six months ended June 30, 1996
and 1995 and $624,000, $538,000 and $335,000 in 1995, 1994 and 1993,
respectively, in accordance with Statement of Financial Accounting Standards
No. 86. Capitalized software development costs are amortized over the
estimated life of the related products (up to four years). Amounts
capitalized, net of amounts amortized, represent 14% and 9% of total software
development expenditures for the six months ended June 30, 1996 and 1995 and
8%, 8% and 7% for 1995, 1994 and 1993, respectively.
 
  Service and Support. Service and support expenses for the first half of 1996
increased $1,444,000, or 28%, as compared to the first half of 1995. Service
and support expenses increased to $10,742,000 in 1995 from $8,629,000 in 1994
and $7,187,000 in 1993. The increases in these expenses are primarily
attributable to the hiring of additional implementation personnel and related
travel. As a percentage of total revenues, service and support expenses
decreased from 35% in 1994 and 1993 to 32% in 1995.
 
  Hardware. Hardware costs for the first half of 1996 increased $470,000, as
compared to the first half of 1995. Hardware costs were $786,000, $682,000 and
$717,000 in 1995, 1994 and 1993, respectively. The fluctuations in hardware
costs are attributable to the proportionate fluctuations in hardware revenues
in each year.
 
  Sales and Marketing. Sales and marketing expenses for the first half of 1996
increased $1,258,000, or 30%, as compared to the first half of 1995. Sales and
marketing expenses increased to $8,832,000 in 1995 from $5,984,000 in 1994 and
$4,455,000 in 1993. The increases in these expenses are primarily attributable
to the expansion of the Company's sales force and related sales support and
marketing activities.
 
  Administration. Administration expenses for the first half of 1996 increased
$1,283,000, or 70%, as compared to the first half of 1995. The increase in
administration expenses is a result of an increase in administrative services
personnel, public company related expenses, amortization of intangible assets
acquired in the Matkon Acquisition and the provision for bad debts, which has
increased with the increase in revenues. Administration expenses increased to
$3,887,000 in 1995 from $2,878,000 in 1994 and $2,545,000 in 1993. The
increases in administration expenses in these periods are primarily a result
of additions to the management team and investments in the Company's
telecommunications and computer infrastructure.
 
  Acquired In-Process Technology. The Company recorded nonrecurring charges of
$8,453,000 in the quarter ended June 30, 1996 for acquired in-process
technology in connection with the Matkon Acquisition. See "Consolidated Pro
Forma Financial Information."
 
  Interest. Prior to its initial public offering in 1995, the Company borrowed
primarily to finance seasonal working capital needs. A portion of the proceeds
from the initial public offering was used to repay all outstanding debt. Net
interest income for the first half of 1996 was $467,000, as compared to net
interest expense of $81,000 in the first half of 1995. The increase in net
interest income in 1996 was primarily attributable to the investment of a
portion of the initial public offering proceeds in interest-bearing
securities.
 
                                      20
<PAGE>
 
  Income Taxes. For the first half of 1996, the income tax benefit was
$2,646,000, compared to an income tax benefit of $139,000 in the first half of
1995. The Company incurred income tax expense of $682,000 (effective rate of
46%) in 1995, $20,000 (effective rate of 42%) in 1994 and $339,000 (effective
rate of 31%) in 1993. The increase in the effective rate in 1995 is
attributable to the incurrence of a greater proportion of nondeductible
travel-related expenses.
 
QUARTERLY RESULTS OF OPERATIONS
 
  The Company's quarterly results of operations have been seasonal, with a
greater proportion of the Company's revenue and operating profitability
occurring in the second half of the year. This seasonality is primarily
attributable to (i) hospital budgeting practices that are characterized by a
disproportionately larger amount of spending in the second half of the year
and (ii) the Company's sales force compensation program, which is based
significantly on achieving sales quotas by the end of September.
 
  The following table sets forth certain unaudited quarterly financial data
for each of the ten quarters ending with the quarter ended June 30, 1996. In
the opinion of management, this unaudited data contains all adjustments
(consisting of only normal recurring adjustments) necessary to present fairly
the results of operations for the periods presented. The operating results for
any quarter are not necessarily indicative of results for any future period.

LIQUIDITY AND CAPITAL RESOURCES
 
  Prior to its initial public offering in 1995, the Company met its capital
needs through a combination of cash flow from operations and proceeds from
issuance of Common Stock in 1993 ($1.1 million) and 1994 ($3.5 million). The
seasonality of the Company's business has historically necessitated the use of
short-term borrowings at various times during the year. The Company currently
has an $18 million unsecured revolving credit line bearing interest at the
prime rate less 0.5% or LIBOR plus 1.25% to 1.75%, which is available to fund
short-term liquidity needs and other general corporate purposes. As of
September 30, 1996, the Company had $300,000 outstanding under the line of
credit.
 
  On October 25, 1995, the Company completed an initial public offering of its
Common Stock. The initial public offering resulted in net proceeds to the
Company of approximately $31,282,000. Management believes that the net proceeds
from this offering, together with existing cash and cash equivalents, cash flow
from operations and borrowings under its line of credit, will be sufficient to
meet the Company's currently anticipated working capital and capital
expenditure requirements for at least the next twelve months.
 
  On May 28, 1996, the Company completed the Matkon Acquisition for a cash
purchase price of approximately $13.9 million. The Matkon division develops,
markets, installs and services a line of hospital materials management software
products which primarily run on a UNIX platform. The Matkon Acquisition
resulted in declines in cash and investment securities, and increases in a
number of asset accounts reflecting the acquisition of tangible and intangible
assets. Increases in prepaid and deferred income taxes arise as a result of the
tax benefits from the write-off of acquired in-process technology. See "Recent
Developments."
 
  The Company has no outstanding material purchase commitments. The Company is
obligated to make minimum royalty payments in the aggregate amount of
approximately $3.2 million under certain license agreements, of which
approximately $400,000 has been paid. See "Recent Developments."
 
  The Company does not believe that inflation has had a material impact on its
results of operations.
 
PENDING ACCOUNTING STANDARD
 
  In accordance with Statement of Financial Accounting Standards No. 123, the
Company will continue to measure compensation cost for stock options using the
intrinsic value based method of accounting prescribed by APB Opinion No. 25,
"Accounting for Stock issued to Employees." The disclosure requirements of
Statement No. 123 will be incorporated into the December 31, 1996 financial
statements.

  The following Business section 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.
 
GENERAL
 
  Enterprise is a healthcare information services company that develops,
markets, installs and services an integrated suite of application software
products that assist healthcare providers in managing their operations. These
resource management systems, which are sold primarily to acute care hospitals,
focus on cost containment and address a broad range of non-clinical management
needs, including materials management, operating room logistics, patient and
staff scheduling and financial management. The Company's healthcare
information systems operate on personal computer networks and make extensive
use of electronic data interchange ("EDI"), enabling its customers to redesign
their resource management functions to enhance efficiency and productivity.
 
INDUSTRY BACKGROUND
 
  Healthcare spending in the United States in 1995 is estimated to have
exceeded $1 trillion. In recent years, governmental and market-driven reform
initiatives have produced significant pressures on healthcare providers to
control costs. In the past, the financial risk of healthcare delivery was
principally absorbed by third-party payors, and providers were not focused on
cost containment. Through managed care and provider capitation arrangements,
the economic risk of healthcare delivery is shifting from payors to providers.
In order to manage this risk, providers are being forced to change the way
that they operate and are increasingly focused on measuring and controlling
the cost of delivering care. The shifting of risk has also encouraged
consolidation among healthcare providers and the emergence of integrated
healthcare organizations in order to achieve economies of scale and operating
efficiencies. See "Risk Factors--Uncertainty and Consolidation in Healthcare
Industry."
 
  The Company believes that a significant need exists for information systems
that address the operational aspects of healthcare delivery. To date, there
has been a lack of emphasis on integrated information systems that effectively
manage these operational costs, which the Company believes constitute a
majority of providers' overall costs. Most existing healthcare information
systems address the billing and clinical aspects of healthcare delivery.
Without the necessary information, it has been difficult for healthcare
managers to allocate efficiently their resources--people, supplies,
facilities, equipment and services--or to understand their costs. These tasks
have been made more difficult by the operating complexity caused by provider
consolidation and the emergence of integrated healthcare organizations.
 
THE ENTERPRISE SOLUTION
 
  Enterprise has developed information systems that address the operational
aspects of healthcare delivery. The Company offers an integrated suite of
resource management systems that assist users in more efficiently managing
people, supplies, facilities, equipment and services. These systems enable
healthcare providers to (i) improve productivity through the redesign and
automation of operational processes and (ii) obtain the information necessary
to measure and control costs. The Company's current product offerings address
materials management, operating room logistics, organization-wide patient and
staff scheduling and financial management, areas which the Company believes
offer significant opportunities for productivity improvement and cost savings.
 
  The Company's systems can be easily integrated with a wide variety of third-
party products. The Company has developed more than two hundred interfaces for
sharing critical information among its applications and other healthcare
information systems. These interfaces ensure that the Company's systems may be
integrated into a healthcare provider's management information systems
environment, thereby eliminating the need to enter the same data more than
once for use in different applications.

STRATEGY
 
  The Company's objective is to continue to be a leading provider of resource
management systems by aggressively using technology to enable healthcare
providers to manage resources, redesign processes and reduce costs. See "Risk
Factors." The Company's strategy includes the following key elements:
 
  Develop and Acquire New Products; Enhance Existing Products. The Company
intends to continue to strengthen existing product lines and expand into
additional operational management areas. This includes (i) developing and
acquiring new technologies and resource management products that complement
existing product lines, (ii) converting the Company's remaining DOS-based
products to a Windows platform, (iii) enhancing system functionality to better
address the needs of integrated healthcare organizations and (iv) developing
additional interfaces with other software products. See "Recent Developments."
 
  Leverage Existing Customer Base. The Company's existing customer base
includes approximately 1,000 acute care hospitals, of which approximately 270
were added as customers when the Company acquired the Matkon division. See
"Recent Developments." Most of the Company's existing customers do not
currently use the Company's entire suite of products. Because of its high
customer retention rate, the Company believes that many of these customers are
candidates for additional components of its product suite and for upgrades to
Windows versions with enhanced functionality. Of those customers (other than
customers of the Matkon division) which have purchased the Company's current
products since January 1, 1991, approximately 97% remained customers at July
1, 1996.
 
  Increase Penetration in Hospital Market. The Company believes a significant
opportunity exists to penetrate further the approximately 2,900 large acute
care hospitals in the United States and Canada. The Company also believes a
significant opportunity now exists with the approximately 3,100 small
hospitals in the United States and Canada. The Company has expanded its direct
sales force and increased its marketing efforts to capitalize on these
opportunities and has established sales teams focused on these targeted
markets.
 
  Expand Presence in Alternate Site Markets. The Company intends to expand its
limited presence in alternate site markets, including outpatient clinics,
ambulatory surgery centers and specialty laboratories. Accordingly, the
Company has expanded its sales force and is in the process of developing
strategic relationships with medical product suppliers.
 
  Develop Additional Distribution Channels. The Company has entered into joint
marketing agreements with group purchasing organizations and hospital
management organizations, which typically provide for these organizations to
recommend the Company's products on a preferred or exclusive basis. The
Company intends to pursue similar agreements, joint ventures or other
arrangements (which may include investments by the Company) with certain
healthcare information system developers and resellers and certain medical
product suppliers.
 
PRODUCTS
 
  The Company's major product lines include materials management, operating
room logistics, organization-wide patient and staff scheduling and financial
management. Generally, the Company's products are personal computer-based and
utilize either a DOS or Windows platform, linked by a number of network
operating systems, including Novell and Microsoft Windows NT. The software
acquired in the Matkon Acquisition primarily operates on minicomputers using a
UNIX platform. The Company's products are modular in design, share a common
database, and may be used independently or bundled together in order to
provide an integrated resource management system solution that enables
healthcare managers to improve efficiency and obtain the information needed to
make strategic decisions regarding resource utilization. The Company's systems
follow the American National Standards Institute (ANSI) HL7 and X12 standards
to exchange data with other software.

CUSTOMER SERVICE AND SUPPORT
 
  The Company provides its customers with services that begin prior to product
implementation and continue for the duration of product use. Service and
support helps customers realize the benefits offered by the Company's software
solutions and provides the Company with a significant base of recurring
revenue. The services offered by the Company are priced separately and include
the following:
 
  Network Verification and Design. Prior to the installation of the Company's
software, customers normally contract for a network analysis, which includes a
survey of the customer's existing information systems, hardware and networks.
 
  Implementation Services. The Company offers implementation services at the
time of a software purchase, including: (i) loading of the software, (ii)
analysis to identify required interfaces with other applications and the
conversion, where necessary, of data from existing systems into the required
formats and (iii) hands-on education.
 
  Customer Education. The Company regularly conducts a wide range of product
educational seminars at its headquarters. More than 1,000 customer
representatives attended Company seminars in 1995.
 
  Service and Support. The Company provides customer service and support after
installation of the software. Included with basic service is 24-hour, toll-
free access to customer support personnel.
 
  Consulting. The Company provides on-site project management, including cost-
benefit analysis, system optimization review and, in some instances, long-term
staff management functions in an outsourcing capacity.
 
CUSTOMERS
 
  The Company's customers include healthcare providers and medical products
suppliers located throughout the United States and in Canada. As of July 1,
1996, the Company had approximately 1,000 healthcare provider customers using
one or more of its systems, of which approximately 270 were added as customers
when the Company acquired the Matkon division in 1996. Of those customers
(other than customers of the Matkon division) which have purchased the
Company's current products since January 1, 1991, approximately 97% remained
customers at July 1, 1996. In addition, more than 90 suppliers have contracted
with or have arranged through the Company to maintain electronic data
interchange with providers. No single customer accounted for more than 5% of
the Company's revenues in either of the last two fiscal years.
 
  Historically, the Company has focused its marketing efforts on the large
hospital market, which comprises the substantial majority of its customer
base. More recently, the Company has expanded its marketing efforts to include
small hospitals and alternate site providers such as outpatient clinics,
ambulatory surgery centers and specialty laboratories. The Company's potential
customers in the United States and Canada include approximately: (i) 2,900
large acute care hospitals (hospitals with 150 or more beds), (ii) 3,100 small
hospitals (hospitals with less than 150 beds), (iii) 7,000 outpatient clinics,
(iv) 2,100 freestanding ambulatory surgery centers and (v) 8,400 hospital-
based and free-standing specialty laboratories. Because the Company has
limited experience in non-hospital markets, it may find that significant
modifications to its products are necessary before they become useful to a
customer or that product pricing may have to be adjusted downward. See "Risk
Factors--Inability to Expand into New Markets."
 
SALES AND MARKETING
 
  The Company sells its products and services through a direct sales force
located throughout the United States and in Canada that is organized according
to market segments. These segments include large hospitals, small hospitals
and clinics, specialty laboratories and groups and healthcare networks. The
sales cycle of the Company's systems and products varies substantially from
customer to customer and typically requires six to twelve months.
 
                                      26
<PAGE>
 
  Large Hospitals. The large hospital sales team consists of five sales
managers, twenty-seven sales representatives and eight sales specialists who
assist in the more technical aspects of the sales process. These sales
representatives are responsible for selling additional components of the
Company's product suite to existing customers as well as selling the entire
product suite to large hospital prospects.
 
  Small Hospitals, Clinics, Ambulatory Surgery Centers and Specialty
Laboratories. The small hospital, clinic and ambulatory surgery center sales
team consists of a sales manager and ten sales representatives. Although the
Company has a number of existing customers in this segment, this market is a
new focus for the Company. Increasingly, potential customers are affiliated
with a healthcare network or group purchasing organizations, thereby enabling
the Company to pursue small hospitals and clinics more cost effectively. This
team also intends to focus on sales of the Company's point-of-use resource
management product to specialty laboratories.
 
  Groups and Healthcare Networks. The group and healthcare network sales team
consists of five sales managers and three sales representatives. They are
responsible for developing business relationships between the Company and
those groups and networks that either own hospitals or exercise influence over
procurement decisions for their member institutions.
 
  The Company has been named a preferred vendor by a number of group
purchasing organizations, including AllHealth, Health Services Corporation of
America, Horizon Healthcare, Inc., Healthcare Services of New England, Quorum
Health Resources, Inc., and University Hospital Consortium Services
Corporation, all of which provide group purchasing management services to
healthcare providers. Pursuant to these preferred vendor agreements, various
systems sold by the Company are endorsed by the group purchasing organizations
as the preferred or exclusively recommended product in a category. There are
more than 1,900 hospital members in these organizations. In addition, the
Company intends to pursue similar agreements, joint ventures or other
arrangements (which may include investments by the Company) with certain
healthcare information system developers and resellers and certain medical
product suppliers.
 
  To support its sales force, the Company conducts comprehensive marketing
programs that include direct mail, focus groups, user conferences, site visits
and customer seminars. Decision makers for the Company's offerings are well
identified. Therefore, direct marketing techniques are emphasized to raise
marketplace awareness, influence decisions and generate qualified leads. The
marketing group consists of one manager and a staff of eight. Customer
seminars are periodically sponsored in association with Microsoft Corporation
("Microsoft") as part of its "Solution Provider" relationship with the
Company. Through this Solution Provider relationship, the Company has been
granted licenses to use Microsoft systems and applications products, server
products, development tools products and pre-release software in order to
assist the Company in providing comprehensive computer solutions to its
customers.
 
BACKLOG
 
  As of June 30, 1996, the Company had approximately $24 million of backlog
(defined as unrecognized up-front fees pursuant to signed contracts) for
software and services that had not yet been delivered, of which $4 million of
backlog is attributable to the Matkon division, as compared to $13 million of
backlog as of June 30, 1995. These backlog amounts do not include revenues
related to annual support, maintenance and enhancement, continuing education
fees and hardware. Based upon its experience, the Company anticipates that a
majority of the backlog will be completed within the next twelve months.
However, the Company is unable to predict with any degree of accuracy the
amount of revenue it will achieve from its backlog in any particular quarter
because the length of the implementation cycle is dependent to a great extent
on factors outside the Company's control. These factors include the date on
which the installation starts (which the customer may delay), the amount of
internal resources that a customer commits to the installation process, the
availability of customer hardware, the structure and size of databases which
need to be converted and the number of interfaces with other information
systems. See "Risk Factors--Variable Quarterly Operating Results; Seasonality"
and "Management's Discussion and Analysis of Financial Condition and Results
of Operations."

PRODUCT DEVELOPMENT AND TECHNOLOGY
 
  The Company's product development strategy is directed at increasing the
functionality and performance of current products, adapting its products for
other healthcare market segments, integrating its products with products from
other healthcare software vendors and creating new products. The Company uses
several methods to identify new product opportunities and enhancements to
current products, including (i) targeted focus groups to collect feedback on
specific requirements, (ii) co-development arrangements with specific
customers and (iii) user conferences to achieve broad consensus on market
needs.
 
  Through the use of co-development arrangements, the Company believes that it
is able to release products that better address current market demands.
Representative co-development partners have included Covenant Healthcare
System, Inc., Harris Methodist Health Systems, Rex Healthcare Services and
Stanford Health Services.
 
  The Company is currently converting its NOVA and TITAN products from DOS to
a Windows client/server platform using an SQL database. Nova.IDN, the Windows-
based version of NOVA, is currently in beta-testing. Its Enterprise Scheduling
and TouchScan products already operate in this environment, while ESP for
Windows is being converted to use an SQL database. In addition, the functions
of the Company's ORBIT product will be incorporated into Enterprise
Scheduling. See "Risk Factors--Product Conversions to Windows."
 
  Generally, the Company's software operates on IBM-compatible personal
computers, using either a DOS or Windows platform, linked by a number of
network operating systems, including Novell and Microsoft Windows NT. The
software acquired in the Matkon Acquisition primarily operates on
minicomputers using a UNIX platform. The Company's products are modular in
design, share common database elements and may be used independently or
together. The Company's systems follow the American National Standards
Institute (ANSI) HL7 and X12 standards to exchange data with other software.
 
  All new products are being developed with a three-tiered, client/server
architecture, using object-oriented methodologies and the C++ programming
language. The new products are designed to run on 32-bit Microsoft Windows
environments and various SQL databases. See "Risk Factors--Ability to Develop
New Software Products; Rapid Technological Change" and "--New Product
Acceptance."
 
COMPETITION
 
  The market for healthcare information systems is intensely competitive. The
competitive factors affecting the market for the Company's software and
services include: vendor and product reputation, availability of products on
preferred computer and communications platforms, scalability, integration with
other applications, functionality and features, ease-of-use, quality of
support, documentation and training, product quality and performance, product
innovation, price and the effectiveness of marketing and sales efforts. The
relative importance of each of these factors depends upon the market segment.
Certain of the Company's competitors have significantly greater financial,
technical, research and development and marketing resources. As a result, they
may be able to respond more quickly to new or emerging technologies and
changes in customer requirements, or to devote greater resources to the
development, promotion, sale and support of their products than the Company.
In addition, consolidation in the healthcare information systems industry may
permit the Company's competitors to have access to increased financial and
administrative resources, greater technological capabilities and to realize
other operational efficiencies and competitive advantages. Moreover,
purchasers may prefer to buy computer systems from a single source provider.
Because the Company focuses exclusively on healthcare resource information
systems (as opposed to clinical or billing systems), it cannot serve as the
sole source of computer software for healthcare organizations. The Company
believes that its experience, its use of technology to create innovative
solutions, its reputation for customer service and its ability to bring
products to market faster than its competition through joint development
partnerships with key customers will enable the Company to compete effectively
in its marketplace. See "Risk Factors--Competition."

PROPRIETARY RIGHTS AND LICENSES
 
  The Company depends significantly upon proprietary technology. The Company
relies on a combination of copyright, trade secret and trademark laws,
confidentiality procedures and nondisclosure and other contractual provisions
to protect its proprietary rights. The Company seeks to protect its software,
documentation and other written materials under trade secret and copyright
laws, which afford only limited protection. The Company believes that, because
of the rapid pace of innovation within the computer software industry, factors
such as the technological and creative skills of its personnel, frequent
product enhancements and ongoing reliable product maintenance and support are
more important in establishing and maintaining a leadership position within
the industry than are the various legal protections of its technology. See
"Risk Factors--Dependence on Proprietary Technology; Risks of Infringement."
 
  Typically, the Company distributes its products under software license
agreements that grant a customer a nonexclusive, nontransferable license to
use the Company's products for the customer's internal operation at designated
sites. In general, the license agreements require the Company to deposit the
source code for its software products in an escrow that may be accessed by the
customer in the event of the Company's liquidation, dissolution or bankruptcy,
or if the Company fails to cure a material breach of contract.
 
  The Company uses the "TouchScan" name under an agreement with a third party.
This agreement does not provide for the Company's use of the name in the
specialty laboratory market. Consequently, the Company sells its point-of-use
resource management product in this market under the name "TS2000."
 
GOVERNMENTAL REGULATION
 
  The healthcare industry is subject to changing political, economic and
regulatory influences that may affect the procurement practices and operation
of healthcare providers. Many federal and state legislators have announced
that they intend to propose programs to reform the United States healthcare
system at both the federal and state level. These programs may contain
proposals to increase governmental involvement in healthcare, lower
reimbursement rates and otherwise change the environment in which providers
operate. Healthcare providers may react to these proposals and the uncertainty
surrounding such proposals by curtailing or deferring investments, including
investments in the Company's products and related services. See "Risk
Factors--Uncertainty and Consolidation in the Healthcare Industry."
 
LEGAL PROCEEDINGS
 
  The Company is not currently involved in any material legal proceedings.
 
EMPLOYEES
 
  As of September 1, 1996, the Company had 410 full-time employees, of which
74 were in sales and marketing, 102 in product development, 191 in customer
services and 43 in administration. None of the Company's employees is
represented by a labor union, and the Company is not aware of any
organizational efforts on behalf of any labor unions involving the Company's
employees.
 
FACILITIES
 
  The Company leases approximately 59,000 square feet of space at its
corporate headquarters located in Wheeling, Illinois, pursuant to leases which
expire on December 31, 2001 with renewal options through December 31, 2006 and
approximately 12,100 square feet of space in Overland Park, Kansas pursuant to
a sublease which expires on June 1, 1997.

expenses incurred in connection with attending meetings. Directors are not
entitled to additional fees for serving on committees of the Board of
Directors. Pursuant to the terms of the formula program of the Company's Long
Term Incentive Plan, each current director of the Company who was not otherwise
employed by the Company when he became a director automatically was granted an
option to purchase 15,000 shares of Common Stock upon his initial election to
the Board of Directors. These options vest in three annual installments of
5,000 shares each. Messrs. Goldstein, Hutchison and Tullman each received
options to purchase 15,000 shares of Common Stock, all of which have vested.
Outstanding options are exercisable at $4.57 per share. When CID became a
principal stockholder in April 1993, it acquired the right to appoint a nominee
to the Company's Board of Directors. Upon election of its nominee, Mr. Compton,
CID was granted an option to purchase 15,000 shares of Common Stock, all of
which are now vested. These options are exercisable at $4.57 per share. When
Morgan Stanley became a principal stockholder in March 1994, it also acquired
the right to appoint a nominee to the Company's Board of Directors. Upon the
election of such nominee (who has since resigned and been replaced by Mr.
Husain), Morgan Stanley was granted an option to purchase 15,000 shares of
Common Stock, 5,000 of which vested on each of April 21, 1995 and April 21,
1996 and 5,000 of which will vest on April 21, 1997. These options are
exercisable at $5.60 per share. Pursuant to the terms of the formula program of
the Company's Long-Term Incentive Compensation Plan, each director of the
Company appointed in the future who is not otherwise employed by the Company
automatically will be granted an option to purchase 5,000 shares of Common
Stock upon his or her initial election to the Board of Directors. The option
will vest in three equal annual installments. See "Management--Compensation
Pursuant to Plans" and "Certain Transactions."

                       OPTION GRANTS IN LAST FISCAL YEAR
 
- --------
(1) Generally, options granted under the Company's Long-Term Incentive
    Compensation Plan become exercisable over a three-year period at the rate
    of 33% per year and have ten-year terms so long as the optionee's
    employment with the Company continues. All options were granted at fair
    market value as determined by the Board of Directors of the Company on the
    date of grant with the exception of the options that were granted in June
    1995. After the June 1995 options were granted, the Company determined
    that the fair market value of these options were $8.00 at the time of
    grant, rather than $5.93. Accordingly, the Company has recorded an
    adjustment for compensation expenses, but the exercise price has not been
    changed.
(2) Future value of current-year grants assuming appreciation in the market
    value of the Common Stock of 5% and 10% per year over the ten-year option
    period. The actual value realized may be greater than or less than
    potential realizable values set forth in the table.
(3) Mr. Mullen's option to purchase 55,000 shares of Common Stock provides for
    vesting in four equal annual installments beginning on January 23, 1995.

EMPLOYMENT AGREEMENTS
 
  Messrs. Tullman, Carey, Mullen, Katz and Carlson have employment agreements
with the Company. The agreements fix each of the officers' base compensation
and provide for reimbursement of travel and other expenses in connection with
such officers' employment. In general, the agreements provide for annual
bonuses of up to 40% of the officer's salary upon attaining certain
performance objectives (such as total revenues and operating income)
determined by the Board of Directors at the beginning of the calendar year.
The current term of the agreements expire on August 31, 1997, are renewable
for successive periods of one year after expiration of the current term and
are terminable by the Company with cause, as defined in the employment
agreements. Upon termination by the Board of Directors without cause, the
executive will be entitled to receive a payment equal to his then current
annual base salary, in addition to all compensation earned but unpaid as of
the date of termination. If so terminated, the Company will be obligated to
pay the following amounts to the Named Executive Officers: Mr. Tullman,
$225,000; Mr. Carey, $170,000; Mr. Mullen, $200,000; Mr. Katz, $190,000; and
Mr. Carlson, $135,000. In addition, if employment of any officer is terminated
by the Company within twelve months of a change in control, the executive will
be entitled to the following additional benefits: (i) any options to purchase
Common Stock, which would otherwise be nonvested, will immediately vest, (ii)
100% of the bonus to which he would have otherwise been entitled had he been
employed on the last day of the calendar year (and then been terminated) and
(iii) payment of his health insurance premiums for the duration of the COBRA
continuation period. These employment agreements also contain confidentiality
and noncompetition provisions for the terms set forth in each agreement.
 
SEVERANCE AGREEMENT
 
  On January 9, 1996, the Company entered into a severance agreement with
Thomas R. Pirelli (the "Severance Agreement"). Pursuant to the Severance

severance payment, the Company paid Mr. Pirelli $200,000, plus $19,682 as
accrued bonus for 1993 and 1994 and $35,000 as a bonus for 1995. In
consideration for such payment, Mr. Pirelli agreed to a general release of all
claims against the Company, a covenant not to sue and an agreement not to
solicit any of the Company's employees through December 31, 1997. Until
January 9, 1998, Mr. Pirelli is subject to noncompetition covenants contained
in his original employment agreement with the Company.
 
COMPENSATION PURSUANT TO PLANS
 
  Long-Term Incentive Compensation Plan. The Board of Directors has adopted
the Enterprise Systems, Inc. Long-Term Incentive Compensation Plan (the "Long-
Term Plan"), which was an amendment and restatement of the Company's 1993
Stock Option Plan. The purpose of the Long-Term Plan is to promote the
interests and enhance the value of the Company by linking the personal
interests of its employees and directors with those of its stockholders, by
inducing individuals of outstanding ability and potential to join and remain
with the Company, by encouraging and enabling eligible employees and directors
to acquire proprietary interests in the Company, and by providing the
participating employees and directors with an additional incentive to promote
the success of the Company.
 
  Awards under the Long-Term Plan may be in the form of stock options
(including both incentive stock options that meet the requirements of Section
422 of the Internal Revenue Code and nonqualified stock options), stock
awards, restricted stock grants, stock appreciation rights ("SARs") and
performance shares (collectively, "Awards"). The Long-Term Plan also includes
the formula program. The formula program provides for the automatic grant of
options to purchase shares of Common Stock to nonemployee directors of the
Company. Pursuant to the terms of the formula program, each director of the
Company who is not otherwise employed by the Company automatically will be
granted an option to purchase 5,000 shares of Common Stock upon his or her
initial election to the Board. The option will vest in three annual
installments, with the first such installment to vest on the first anniversary
of the option grant date.
 
                                      36
<PAGE>
 
  Awards will be evidenced by a written agreement, setting forth the terms and
conditions of that Award, which need not be identical for each Award. Any
Award issued under the Long-Term Plan that is forfeited, expired or terminated
prior to vesting or exercise will again become available for grant under the
Plan.
 
  The Long-Term Plan is administered by the Compensation Committee (the
"Committee"). The Committee has discretion to determine which "key employees"
and "key non-employees" (non-employee directors, consultants or independent
contractors) will be recipients of Awards under the Long-Term Plan, and to
establish the terms, conditions and limitations of each Award (subject to the
terms of the Long-Term Plan and the applicable provisions of the Internal
Revenue Code), including the type and amount of the Award, the number of
shares of Common Stock to be subject to any Award of options or restricted
stock, or the amount of cash or rights to be included in an Award, the
exercise price of any options, and the date or dates upon which options become
exercisable or upon which any restrictions applicable to any Award lapse. The
Committee also has full power to construe and interpret the Long-Term Plan and
the Awards granted under the Long-Term Plan, and to establish rules and
regulations necessary or advisable for its administration. The determination
of the Committee with respect to any matter under the Long-Term Plan to be
acted upon by the Committee is conclusive and binding.
 
  Awards under the Long-Term Plan may be granted only to key employees and key
non-employees of the Company and its subsidiaries. The Committee determines
whether a particular employee or non-employee qualifies as a key employee or
non-employee. Awards also may be granted to a prospective employee,
conditioned upon such person becoming an employee. Members of the Committee
are not eligible for Awards while serving on the Committee, unless the Award
is made pursuant to a formula that states the amount and price of the Common
Stock to be awarded to the members of the Committee and specifies the timing
of the Award.
 
  The maximum number of shares of Common Stock which may be issued and sold
under the Long-Term Plan, subject to adjustment, is 1,114,846 shares. As of
September 1, 1996, participants in the Long-Term Plan held options to purchase
an aggregate of 910,801 shares of Common Stock at per share exercise prices
ranging from $4.57 to $38.50, with a weighted average exercise price per share
of $11.13. As of September 1, 1996, no shares of Common Stock have been issued
pursuant to restricted stock awards and a total of 22,163 shares of Common
Stock remain available for issuance under the Plan. In general, options
automatically vest upon a change in control of the Company depending on the
terms of each individual grant.
 
  401(k) Savings Plan. The Enterprise Systems, Inc. 401(k) Savings Plan (the
"401(k) Plan") is a tax qualified "cash or deferred" plan under Section 401(k)
of the Internal Revenue Code in which all of the Company's employees,
including executive officers, are eligible to participate after completing
three months of service. Participants are able to defer up to 15% of their
salary (to a maximum of $9,500 in 1996, as adjusted annually) to be
contributed to a trust fund and invested, at the participant's election, in
equity or fixed income investments offered by the administrator of the 401(k)
Plan. The Company has the discretion to match a percentage of the
contributions made to the 401(k) Plan in any year. In 1996, the Company will
match 25% of the first $1,000 of salary contributed by each employee, not to
exceed a maximum annual contribution of $250 by the Company. The employees'
contributions are fully vested and nonforfeitable at all times. A
participant's contributions become distributable upon the participant's
retirement, death, disability or other termination of employment and, under
certain emergency circumstances, may be distributed during employment.
 
  In December 1995, the Company merged its ESOP into the 401(k) Plan with
account balances from the ESOP transferring to the 401(k) Plan. The trustee of
the 401(k) Plan is appointed from time to time by the Board of Directors and
currently is Emjay Corporation (the "Trustee"). Shares of Common Stock that
have been allocated to participants under the ESOP and which remain as part of
their account balances in the 401(k) Plan will be voted by the Trustee in
accordance with directions from each participant. Any allocated Common Stock
with respect to which voting directions are not given will be voted by the
Trustee.

  In April 1993, the Company and ESI Research & Development Limited
Partnership (the "Partnership") entered into a letter agreement, pursuant to
which the Company purchased from the Partnership all right, title and interest
in and to certain capital asset management software for a purchase price of
$200,000. Mr. Pirelli, a Director of the Company, was a limited partner with a
7% ownership interest in the Partnership prior to its dissolution in June

valuation.
 
  On December 29, 1988, the Company made a term loan of approximately
$3,100,000 at an interest rate of 8.94% to fund the ESOP. The ESOP serviced
the principal and interest requirements on this loan with contributions from
the Company. The final payment was made in December 1994. Company
contributions to the ESOP amounted to approximately $590,000 and $543,000 for
1993 and 1994, respectively.
 
  The Company entered into an agreement with Broadview Associates LLC
("Broadview"), effective as of February 1, 1996, pursuant to which Broadview

Acquisition. Bernard Goldstein, a Director of the Company and a member of the
Compensation Committee, is a Managing Director of Broadview.

                         DESCRIPTION OF CAPITAL STOCK
 
  The authorized capital stock of the Company consists of 30,000,000 shares of
Common Stock, par value $.01 per share, and 1,000,000 shares of Preferred
Stock, par value $.01 per share. As of September 1, 1996, there were 7,519,581
shares of Common Stock outstanding, held of record by 78 stockholders, and no
shares of Preferred Stock were outstanding.
 
COMMON STOCK
 
  Holders of Common Stock are entitled to one vote per share for the election
of directors and all other matters submitted for stockholder vote, except
matters submitted to the vote of another class or series of shares. Holders of
Common Stock are not entitled to cumulative voting rights. Therefore, the
holders of a majority of the shares voting for the election of directors can
elect all of the directors if they choose to do so. The holders of Common
Stock are entitled to dividends in such amounts and at such times, if any, as
may be declared by the Board of Directors out of funds legally available
therefor. The Company has not paid any dividends on its Common Stock and does
not anticipate paying any cash dividends on such stock in the foreseeable
future. Upon liquidation, dissolution or winding up of the Company, the
holders of Common Stock are entitled to share ratably in all net assets
available for distribution to stockholders after payments to creditors. The
Common Stock is not redeemable and has no preemptive or conversion rights. See
"Dividend Policy."
 
  The rights of the holders of Common Stock are subject to the rights of the
holders of any Preferred Stock which may, in the future, be issued. All
outstanding shares of Common Stock are, and the shares of Common Stock to be
sold by the Company in this offering when issued will be, duly authorized,
validly issued, fully paid and nonassessable.
 
PREFERRED STOCK
 
  The Company's Certificate of Incorporation authorizes 1,000,000 shares of
Preferred Stock. The Board of Directors has the authority to issue the
Preferred Stock in one or more series and to fix the price, rights,
preferences, privileges and restrictions thereof, including dividend rights,
dividend rates, conversion rights, voting rights, terms of redemption,
redemption prices, liquidation preferences and the number of shares
constituting any series or the designation of such series, without further
vote or action by the stockholders. The issuance of Preferred Stock may have
the effect of delaying, deferring or preventing a change in control of the
Company without further action by the stockholders and may adversely affect
the voting and other rights of the holders of Common Stock. The issuance of
Preferred Stock with voting and conversion rights may adversely affect the
voting power of the holders of Common Stock, including the loss of voting
control to others. Upon consummation of this offering, no shares of Preferred
Stock will be outstanding. The Company has no present intention to issue
shares of Preferred Stock.
 
ANTITAKEOVER EFFECTS OF PROVISIONS OF THE CERTIFICATE OF INCORPORATION, BY-
LAWS AND DELAWARE LAW
 
  Certificate of Incorporation and By-Laws. The Company's Certificate of
Incorporation provides that the Board of Directors will be divided into three
classes of directors, each class constituting approximately one-third of the
total number of directors and with the classes serving staggered three-year
terms. In addition, the Certificate of Incorporation provides that all
stockholder action must be effected at a duly called meeting and not by a
consent in writing. The By-Laws provide that the Company's stockholders may
call a special meeting of stockholders only upon a request of stockholders
owning at least 50% of the Company's capital stock. These provisions of the
Certificate of Incorporation and By-Laws could discourage potential
acquisition proposals and could delay or prevent a change in control of the
Company. These provisions are intended to enhance the likelihood of continuity
and stability in the composition of the Board of Directors and in the policies
formulated by the Board of Directors and to discourage certain types of
transactions that may involve an actual or threatened change of control of the
Company. These provisions are designed to reduce the vulnerability of
 
                                      41
<PAGE>
 
the Company to an unsolicited acquisition proposal. The provisions also are
intended to discourage certain tactics that may be used in proxy fights.
However, such provisions could have the effect of discouraging others from
making tender offers for the Company's shares and, as a consequence, they also
may inhibit fluctuations in the market price of the Company's shares that
could result from actual or rumored takeover attempts. Such provisions also
may have the effect of preventing changes in the management of the Company.
See "Risk Factors--Effect of Certain Charter Provisions; Antitakeover Effects
of Certificate of Incorporation, By-Laws and Delaware Law."
 
  Delaware Takeover Statute. The Company is subject to Section 203 of the
Delaware General Corporation Law ("Section 203"), which, subject to certain
exceptions, prohibits a Delaware corporation from engaging in any business
combination with any interested stockholder for a period of three years
following the date that such stockholder became an interested stockholder,
unless: (i) prior to such date, the board of directors of the corporation
approved either the business combination or the transaction that resulted in
the stockholder becoming an interested stockholder; (ii) upon consummation of
the transaction that resulted in the stockholder becoming an interested
stockholder, the interested stockholder owned at least 85% of the voting stock
of the corporation outstanding at the time the transaction commenced,
excluding for purposes of determining the number of shares outstanding those
shares owned (a) by persons who are directors and also officers and (b) by
employee stock plans in which employee participants do not have the right to
determine confidentially whether shares held subject to the plan will be
tendered in a tender or exchange offer; or (iii) on or subsequent to such
date, the business combination is approved by the board of directors and
authorized at an annual or special meeting of the stockholders, and not by
written consent, by the affirmative vote of at least 66 2/3% of the
outstanding voting stock that is not owned by the interested stockholder.
 
  Section 203 defines business combination to include: (i) any merger or
consolidation involving the corporation and the interested stockholder, (ii)
any sale, transfer, pledge or other disposition of 10% or more of the assets
of the corporation involving the interested stockholder, (iii) subject to
certain exceptions, any transaction that results in the issuance or transfer
by the corporation of any stock of the corporation to the interested
stockholder, (iv) any transaction involving the corporation that has the
effect of increasing the proportionate share of the stock of any class or
series of the corporation beneficially owned by the interested stockholder or
(v) the receipt by the interested stockholder of the benefit of any loans,
advances, guarantees, pledges or other financial benefits provided by or
through the corporation. In general, Section 203 defines an interested
stockholder as any entity or person beneficially owning 15% or more of the
outstanding voting stock of the corporation and any entity or person
affiliated with or controlling or controlled by such entity or person.
 
LIMITATION OF LIABILITY AND INDEMNIFICATION
 
  Limitation of Liability. As permitted by the Delaware General Corporation
Law, the Company's Certificate provides that directors of the Company shall
not be personally liable for monetary damages to the Company for certain
breaches of their fiduciary duty as directors, unless they violated their duty
of loyalty to the Company or its stockholders, acted in bad faith, knowingly
or intentionally violated the law, authorized illegal dividends or
redemptions, or derived an improper personal benefit from their action as
directors. This provision would have no effect on the availability of
equitable remedies or nonmonetary relief, such as an injunction or rescission
for breach of the duty of care. In addition, the provision applies only to
claims against a director arising out of his or her role as a director and not
in any other capacity (such as an officer or employee of the Company).
Further, liability of a director for violations of the federal securities laws
will not be limited by this provision. Directors will, however, no longer be
liable for monetary damages arising from decisions involving violations of the
duty of care which could be deemed grossly negligent.
 
  Indemnification. The Certificate provides that directors and officers of the
Company shall be indemnified by the Company to the fullest extent authorized
by Delaware law, as it now exists or may in the future be amended, against all
expenses and liabilities reasonably incurred in connection with service for or
on behalf of the Company. The Certificate also authorizes the Company to enter
into one or more agreements with any
 
                                      42
<PAGE>
 
person which provide for indemnification greater or different from that
provided in the Certificate. The Company has entered into indemnification
agreements with all current members of the Board of Directors.
 
REGISTRATION RIGHTS
 
  Holders of 657,857 shares of Common Stock have certain demand and piggyback
registration rights with respect to the registration under the Securities Act
of shares of Common Stock ("Registrable Shares") held by them from time to
time. Certain holders of the Registrable Shares are Directors and 5% or
greater beneficial stockholders of the Company. See "Certain Transactions."
The holders of not less than 25% of the Registrable Shares may request that
the Company register all or part of their Registrable Shares under the
Securities Act. In addition, if the Company proposes to register any of its
securities under the Securities Act for its own account, holders of
Registrable Shares may require the Company to include all or a portion of
their Registrable Shares in the registration, provided, among other
conditions, that the managing underwriter (if any) of any such offering has
the right, subject to certain conditions, to limit the number of Registrable
Shares included in the registration. In general, all fees, costs and expenses
of such registrations (other than underwriting commissions, dealer's fees,
brokers' fees and applicable concessions) will be borne by the Company. The
rights of holders of Registrable Shares to demand or participate in such
registrations terminate on the earlier of (i) the date all Registrable Shares
are registered under the Securities Act and disposed of in accordance with the
registration statement covering them, or (ii) the date all Registrable Shares
are sold or transferred in accordance with the requirements of Rule 144.
 
RECAPITALIZATION
 
  In October 1995, the Company reincorporated in the State of Delaware and
became a holding company with a wholly owned operating subsidiary (the
"Recapitalization"). The Recapitalization was accomplished in two steps.
First, the Company merged with a wholly owned Delaware subsidiary, with such
subsidiary being the surviving entity. Second, the Company became a holding
company by transferring substantially all of its assets and liabilities to a
new wholly owned Illinois subsidiary named "Enterprise Systems, Inc." See
"Risk Factors--Holding Company Structure."
 
TRANSFER AGENT AND REGISTRAR
 
  The transfer agent and registrar for the Common Stock is Harris Trust and
Savings Bank, Chicago, Illinois.

                        SHARES ELIGIBLE FOR FUTURE SALE
 
  Upon completion of this offering, the Company will have 8,119,581 shares of
Common Stock outstanding, assuming no exercise of options after September 1,
1996. Substantially all of these shares will be freely tradeable without
restriction under the Securities Act or may currently be sold in accordance
with Rule 144 under the Securities Act ("Rule 144"). In addition, the Company
has registered on a registration statement on Form S-8 a total of 1,114,846
shares of Common Stock reserved for issuance under the Company's Long-Term
Plan, of which options for 181,882 shares have been exercised as of September
1, 1996. The remaining 932,964 shares, when and if issued, would be freely
tradeable (unless acquired by an affiliate of the Company, in which case they
would be subject to volume and other limitations under Rule 144).
 
  The Directors and executive officers of the Company and the Company's 401(k)
Plan, beneficially holding an aggregate of 2,784,169 shares of Common Stock as
of September 1, 1996, have entered into lock-up agreements pursuant to which
such stockholders have agreed not to sell or otherwise dispose of any shares
of Common Stock for a period of 90 days after the date of this Prospectus
without the prior written consent of Robertson, Stephens & Company. Upon
expiration of the lock-up period, these shares will be eligible for immediate
sale, subject in certain cases to volume and other limitations under Rule 144.
See "Plan of Distribution."
 
  Generally, shares of Common Stock that have not been registered under the
Securities Act or that are held by affiliates of the Company (whether or not
registered) are deemed "restricted" securities under Rule 144. In general,
under Rule 144 as currently in effect, a person (or persons whose shares are
aggregated) who has beneficially owned "restricted" shares for at least two
years, including a person who may be deemed an affiliate of the Company, is
entitled to sell within any three-month period a number of shares of Common
Stock that does not exceed the greater of 1% of the then outstanding shares of
Common Stock of the Company (81,196 shares after giving effect to this
offering) or the average weekly trading volume of the Common Stock as reported
through the Nasdaq National Market during the four calendar weeks preceding
such sale. Sales under Rule 144 are also subject to certain restrictions
relating to manner of sale, notice and the availability of current public
information about the Company. In addition, under Rule 144(k) of the
Securities Act, a person who is not an affiliate of the Company at any time
within 90 days preceding a sale, and who has beneficially owned shares for at
least three years, would be entitled to sell such shares immediately following
this offering without regard to the volume limitations, manner of sale
provisions or notice or other requirements of Rule 144. The Commission has
proposed to amend the holding period required by Rule 144 to permit sales of
"restricted" securities after one year rather than two years (and two years
rather than three years for "non-affiliates" under Rule 144(k)).
 
  No predictions can be made of the effect, if any, that shares eligible for
market sale will have on the market price of Common Stock prevailing from time
to time. Nevertheless, sales of substantial amounts of shares of Common Stock
in the public market could adversely affect the market price of the Common
Stock. See "Risk Factors--Shares Eligible for Future Sale."

                             PLAN OF DISTRIBUTION
 
  The shares of Common Stock being offered hereby are being offered for sale
by the Company principally to selected institutional investors. Robertson,
Stephens & Company LLC and Wessels, Arnold & Henderson, L.L.C. (the "Placement
Agents") have been retained to act, on a best efforts basis, as the exclusive
agents for the Company in arranging sales of Common Stock to be sold by the
Company in the offering. The Placement Agents may retain one or more
subplacement agents in connection with the offering. The closing of the
offering is not conditioned on the sale of any minimum number of shares of
Common Stock offered hereby.
 
  The Placement Agents are not obligated to purchase any of the Common Stock
offered hereby. It is anticipated that the Placement Agents will obtain
indications of interest from potential investors for the amount of the
offering and that, after obtaining such indications of interest, the Company
will fix the price for the offering and the Placement Agents will confirm
orders to purchase shares of Common Stock from the Company at that price. The
Company does not intend to request effectiveness of the Registration Statement
for the offering until the Company fixes the offering price. However, orders
will not be confirmed until the Registration Statement has been declared
effective. The Company may sell less than all of the shares of Common Stock
offered hereby. There is no required minimum number of shares that must be
sold as a condition to completion of the offering. Confirmations containing
requests for written commitments from investors purchasing in the offering and
final prospectuses will be distributed to all investors as soon as practicable
after pricing. No investor funds will be accepted prior to the effective date
of the Registration Statement. Upon closing, (i) the Company will deliver to
each investor the number of shares purchased by such investor in accordance
with instructions previously delivered by the Placement Agents on behalf of
the investors, (ii) each investor will deliver to the Company immediately
available funds in an amount equal to the aggregate purchase price of the
shares of Common Stock being sold to such investor and (iii) the Company will
pay the Placement Agents their fee. The offering will not continue after the
closing.
 
  The Company has agreed to pay to the Placement Agents a fee equal to 5.5% of
the purchase price of the shares. The Company has also agreed to indemnify the
Placement Agents against certain liabilities, including liabilities under the
Securities Act, or to contribute to payments that the Placement Agents may be
required to make in respect thereof.
 
  The Company, its Directors, executive officers and 401(k) Plan have agreed
that, subject to certain limited exceptions, they will not, for a period of 90
days after the date of this Prospectus, sell, offer to sell, contract to sell
or otherwise dispose of any of their shares of Common Stock (except for sales
described in or contemplated by this Prospectus) or other securities of the
Company without the prior written consent of Robertson, Stephens & Company,
except that the Company may, without such consent, grant options and issue
shares of Common Stock under the Long-Term Plan.

                         INDEPENDENT AUDITORS' REPORT
 
Board of Directors and Stockholders
Enterprise Systems, Inc.:
 
  We have audited the accompanying consolidated balance sheets of Enterprise
Systems, Inc. and subsidiary (the "Company") as of December 31, 1994 and 1995,
and the related consolidated statements of operations, stockholders' equity
and cash flows for each of the years in the three-year period ended December
31, 1995. These consolidated financial statements are the responsibility of
the Company's management. Our responsibility is to express an opinion on the
consolidated 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 consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Enterprise
Systems, Inc. and subsidiary as of December 31, 1994 and 1995, and the results
of their operations and their cash flows for each of the years in the three-
year period ended December 31, 1995 in conformity with generally accepted
accounting principles.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                       DECEMBER 31, 1993, 1994 AND 1995
 
  (AMOUNTS AND DISCLOSURES APPLICABLE TO JUNE 30, 1995 AND JUNE 30, 1996 ARE
                                  UNAUDITED.)
 
(1) DESCRIPTION OF BUSINESS
 
  Enterprise Systems, Inc. develops, markets, installs and services an
integrated suite of application software products that assist healthcare
providers in managing their operations.
 
(2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
 Principles of Consolidation
 
  The consolidated financial statements include the accounts of Enterprise
Systems, Inc. and its subsidiary (the "Company"). All intercompany accounts
and transactions have been eliminated in consolidation.
 
 Revenue Recognition
 
  Revenues from software licensing and installation fees are recognized in
accordance with Statement of Position 91-1, "Software Revenue Recognition."
After contract signing and software delivery, revenues are recognized as the
installation services are performed. Education and consulting revenues are
recognized as the related services are performed. Revenue from first year
maintenance fees implicit in new software licenses and revenue from separately
priced maintenance agreements are recognized ratably over the maintenance
periods. Services revenues include fees from software installation, ongoing
maintenance, education and consulting. Commissions are generally paid in the
month following contract signing and are recognized as the related revenue is
recognized.
 
 Cash Equivalents and Investment Securities
 
  Cash equivalents are comprised of certain highly liquid investments with
original maturities of less than three months. Investment securities consist
of U.S. Treasury notes and municipal bonds with original maturities generally
ranging from one to two years.
 
  Investment securities are classified as held-to-maturity, as the Company has
the ability and intent to hold such securities until maturity. Held-to-
maturity securities are recorded at amortized cost, adjusted for the
amortization or accretion of premiums or discounts. Premiums and discounts are
amortized or accreted over the life of the related security as an adjustment
to yield using the straight-line method, which approximates the effective
interest method. Interest income is recognized when earned.
 
 Property and Equipment
 
  Property and equipment are stated at cost. Depreciation is computed using
the straight-line method based on the estimated useful lives, ranging from
three to five years, of the various classes of property. Amortization of
leasehold improvements is computed over the shorter of the lease term or
estimated useful life of the asset.
 
 Income Taxes
 
  Deferred income taxes are accounted for under the asset and liability
method. 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 year in which
 
                                      F-7
<PAGE>
 
                           ENTERPRISE SYSTEMS, INC.
 
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
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 of enactment.
 
 Software Development
 
  Software development costs are accounted for in accordance with Statement of
Financial Accounting Standards No. 86, "Accounting for the Costs of Computer
Software to be Sold, Leased or Otherwise Marketed." Costs associated with the
planning and designing phase of software development, including coding and
testing activities necessary to establish technological feasibility, are
classified as software development and expensed as incurred. Once
technological feasibility has been established, additional costs incurred in
development, including coding, testing and documentation writing, are
capitalized until general release.
 
  Amortization of developed software is provided on a product-by-product basis
over the estimated economic life of the software, generally four years, using
the straight-line method. Amortization commences when a product is available
for general release to customers. Unamortized software development costs
determined to be in excess of the net realizable value of a product are
expensed at the date of such determination.
 
 Computation of Net Income (Loss) Per Share
 
  Net income (loss) per share is based on the weighted average number of
shares outstanding and includes the dilutive effect of unexercised stock
options using the treasury stock method. Net loss per share is based on the
weighted average number of shares outstanding and does not include the effect
of unexercised stock options.
 
  Pursuant to Securities and Exchange Commission Staff Accounting Bulletin No.
83, options for common stock granted by the Company during the twelve months
immediately preceding the initial public offering (using the treasury stock
method and the mid-point of the then proposed public offering price) have been
included in the calculation of common and common equivalent shares as if they
were outstanding for all periods presented.
 
 Use of Estimates
 
  The preparation of financial statements in conformity with generally
accepted accounting principles necessarily requires management to make
estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the date of
the financial statements and the reported amounts of revenues and expenses
during the reporting period. Actual results could differ from these estimates.
 
 Fair Value of Financial Instruments
 
  The Company's financial instruments are valued at their carrying amounts
which are reasonable estimates of fair value due to the relatively short
period to maturity of the instruments.
 
 Interim Financial Statements
 
  The financial statements as of June 30, 1996 and for the six months ended
June 30, 1995 and 1996 are unaudited. In the opinion of management, the
unaudited financial statements contain all adjustments (consisting of only
normal recurring adjustments) necessary to present fairly the financial
position and results of operations for such periods. Results of operations for
interim periods are not necessarily indicative of results that will be
achieved for the entire year.
 
(3) INITIAL PUBLIC OFFERING
 
  On October 25, 1995, the Company completed an initial public offering of its
common stock in which 1,800,000 shares were sold by the Company. On November
21, 1995, the Company's underwriters exercised their over-allotment option to
purchase an additional 363,750 shares of common stock. The sale of the
Company's common stock resulted in net proceeds of approximately $31,282,000.

  The Company believes its history of profitability and taxable income and its
utilization of tax planning sufficiently supports the value of the deferred tax
assets. Accordingly, the Company has not recorded a valuation allowance as it
is more likely than not that all deferred tax assets will be recovered.

(10) STOCK OPTIONS
 
  In 1993, the Company adopted a stock option plan under which certain
employees and nonemployee directors may be granted the right to purchase
shares of common stock. In October 1995, this stock option plan was amended to
create the Company's Long-Term Incentive Compensation Plan. Stock options vest
over periods ranging from three to five years. Stock options expire ten years
from the date granted. At December 31, 1995 and June 30, 1996, there were
128,416 and 119,049 shares, respectively, reserved for future grants.
 
  In June 1995, stock options were granted to purchase 55,000 shares of the
Company's common stock at an exercise price of $5.93 per share. Deferred
compensation has been recorded representing the difference between the fair
market value of the options at the date of grant and the exercise price.
Compensation expense representing the amortization of the deferred
compensation is recognized over the vesting period of the stock options.
 
  Stock option transactions from January 1, 1994 to June 30, 1996 relating to
the stock option plan are summarized as follows:

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
(13) BUSINESS SEGMENT INFORMATION
 
  The Company operates in one industry segment. The Company markets its
products in the United States and in Canada. No customer accounted for 5% or
more of revenue for the years presented.
 
(14) SUBSEQUENT EVENTS (UNAUDITED)
 
  On January 2, 1996, the Company entered into a distribution agreement to
distribute, install and support a staff scheduling system. The agreement
provides the Company with exclusive territorial rights to the United States
for a term of two years. The Company's minimum royalty commitment over the
term of the agreement is approximately $1.2 million.
 
  On March 22, 1996, the Company entered into a license agreement with
FlexiInternational Software, Inc. ("FLEXI") that allows the Company to
incorporate the FLEXI general ledger and accounts payable applications into
the Company's products for distribution in the United States healthcare
market. The Company has an exclusive right to sell the FLEXI applications in
the United States upon meeting certain sales levels.
 
  On May 28, 1996, the Company purchased certain net assets of the materials
management division of Continental Healthcare Systems, Inc. for approximately
$13.9 million. The acquisition was accounted for under the purchase method.
Accordingly, the purchase price has been allocated to identifiable tangible
and intangible assets acquired and liabilities assumed based on their
estimated fair values. Approximately $8.4 million of the purchase price was
allocated to acquired in-process technology which has been charged to
operations in the consolidated statement of operations for the quarter ended
June 30, 1996. Such allocation is subject to change and is not necessarily
indicative of the ultimate purchase price allocation.

                         INDEPENDENT AUDITORS' REPORT
 
The Boards of Directors
Continental Health Systems, Inc.
and Enterprise Systems, Inc.:
 
  We have audited the accompanying statements of assets to be acquired and
liabilities to be assumed as of November 30, 1994 and 1995 and the statements
of revenues and expenses and cash flows for the years ended November 30, 1994
and 1995 of the Matkon Product Line of Continental Health Systems, Inc.
(Continental). These financial statements are the responsibility of
Continental'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.
 
  As discussed in notes 1(a) and 7 to the financial statements, on May 28,
1996 Continental sold certain assets and liabilities of the Matkon Product
Line of Continental to Enterprise Systems, Inc.
 
  In our opinion, the financial statements referred to above present fairly,
in all material respects, the assets to be acquired and liabilities to be
assumed as of November 30, 1994 and 1995 and revenues and expenses and cash
flows for the years ended November 30, 1994 and 1995, in conformity with
generally accepted accounting principles.

                          NOVEMBER 30, 1994 AND 1995
 
   (AMOUNTS AND DISCLOSURES APPLICABLE TO MAY 31, 1995 AND MAY 31, 1996 ARE
                                  UNAUDITED)
 
(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
 (a) Organization
 
  The Matkon product line (Matkon) of Continental Health Systems, Inc.
(Continental) designs, develops, markets, installs and services application
software products that assist health care providers in managing their
operations.
 
  As more fully described in note 7, Continental has entered into an agreement
to sell assets and liabilities of the Matkon product line to Enterprise
Systems, Inc. (Enterprise).
 
 (b) Basis of Presentation
 
  Matkon's financial results have historically been reported in a combined
manner with the results of Continental. For purposes of this presentation, the
accompanying financial statements present only those assets and liabilities of
Matkon to be acquired by Enterprise as of November 30, 1994 and 1995. The
statements of revenues and expenses of Matkon for the years ended November 30,
1994 and 1995 include only the operating results of Matkon presented on a
stand-alone basis, excluding the impact, if any, on Continental's consolidated
income tax provision.
 
 (c) Inventories
 
  Inventories are valued at the lower of cost or market using the first-in,
first-out (FIFO) method.
 
 (d) Property and Equipment
 
  Property and Equipment are recorded at cost. Depreciation is calculated on
the straight-line method over the estimated useful lives of the assets which
range from three to five years. Leasehold improvements are amortized on the
straight-line method over the shorter of the lease term or estimated useful
life of the assets.
 
 (e) Software Development Costs
 
  Costs incurred internally in creating computer software products are
expensed until technological feasibility has been established upon completion
of a detail program design. Thereafter, all software development costs are
capitalized and subsequently reported at the lower of amortized cost or net
realizable value. Capitalized costs are amortized based on current and future
revenue for each product, with minimum annual amortization equal to the
straight-line amortization over the estimated economic life of the product.
Continental is amortizing capitalized costs on a straight-line basis over five
years.
 
 (f) Revenue Recognition
 
  Revenues from software licensing and installation fees are recognized in
accordance with Statement of Position 91-1, "Software Revenue Recognition."
After contract signing and software delivery, revenues are recognized as the
installation services are performed. Custom programming and consulting
revenues are recognized as the related services are performed. Revenue from
maintenance agreements is recognized ratably over the maintenance periods.
Service revenues include fees from software installation, ongoing maintenance,
custom programming and consulting.
 
 (g) Use of Estimates
 
  The preparation of financial statements in conformity with generally
accepted accounting principles necessarily requires management to make
estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the date of
the financial statements and the reported amounts of revenues and expenses
during the reporting period. Actual results could differ from these estimates.

                  NOTES TO FINANCIAL STATEMENTS--(CONTINUED)
 
 (h) Fair Value of Financial Instruments
 
  Financial instruments consisting of current receivables and accounts payable
are carried at cost, which approximates fair value, as a result of the short-
term nature of the instruments. The fair value of the noncurrent receivables
is estimated to be $829,000 and $432,000 at November 30, 1994 and 1995,
respectively, based on Continental's estimated cost of capital.
 (i) Interim Financial Statements
 
 
  The financial statements as of May 31, 1996 and for the six months ended May
31, 1995 and 1996 are unaudited. In the opinion of management, the unaudited
financial statements contain all adjustments (consisting of only normal
recurring adjustments) necessary to present fairly the financial position and
results of operations for such periods. Results of operations for interim
periods are not necessarily indicative of results that will be achieved for
the entire year.
 
(2) PROPERTY AND EQUIPMENT
 
  A summary of fixed assets follows as of November 30, 1995 and 1994:

line.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
  The Company is a Delaware corporation, subject to the applicable
indemnification provisions of the General Corporation Law of the State of
Delaware (the "DGCL"). Section 145 of the DGCL empowers a Delaware corporation
to indemnify, subject to the standards therein prescribed, any person in
connection with any action, suit or proceeding brought or threatened because
such person is or was a director, officer, employee or agent of the
corporation or was serving as such with respect to another corporation or
other entity at the request of such corporation.
 
  In accordance with Section 102(b)(7) of the DGCL, Article XIII of the
Corporation's Certificate of Incorporation provides that "no director of the
Corporation shall be personally liable to the Corporation or its stockholders
for monetary damages for breach of fiduciary duty as a director,
notwithstanding any provision of law imposing such liability except for
liability (i) for any breach of the director's duty of loyalty to the
Corporation or its stockholders, (ii) for acts or omissions not in good faith
or which involve intentional misconduct or a knowing violation of law, (iii)
under Section 174 of the DGCL, as the same exists or hereafter may be amended,
or (iv) for any transaction from which the director derived an improper
personal benefit. If the DGCL is amended to authorize the further elimination
or limitation of liability of directors, then the liability of a director of
the Corporation, in addition to the limitation on personal liability provided
herein, shall be limited to the fullest extent permitted by an amended DGCL.
Any repeal or modification of this Article XIII by the stockholders of the
Corporation shall be prospective only, and shall not adversely affect any
limitation on the personal liability of a director of the Corporation existing
at the time of such repeal or modification."
 
  The Company's Certificate of Incorporation and By-Laws contain provisions
that require the Company to indemnify its directors and officers to the
fullest extent permitted by Delaware law.
 
  The Company has entered into indemnification agreements with each of its
executive officers and directors in which the Company agrees to indemnify and
hold harmless the officer or director to the fullest extent permitted by
applicable law against any and all reasonable attorneys' fees and all other
reasonable expense, cost, liability and loss (including a mandatory obligation
by the Company to advance reimbursement of legal fees and expenses) paid or
reasonably incurred by such officer or director or on his or her behalf in
connection with any threatened, pending or completed action, suit or
proceeding, or any inquiry or
 
                                     II-1
<PAGE>
 
investigation not initiated by the officer or director that he or she believes
in good faith might lead to a proceeding, inquiry or investigation (a
"Proceeding"), relating to the fact that the officer or director is or was a
director, officer, employee or agent of the Company, or is or was serving at
the request of the Company as a director, officer, employee, trustee, agent or
fiduciary of another corporation, partnership, joint venture, employee benefit
plan, trust or other enterprise, or by reason of any action or inaction by the
officer or director in such capacity. However, the Company's obligation to
indemnify the officer or director is subject to a determination by: (i) the
Company's Board of Directors, by vote of the majority of disinterested
directors; (ii) under certain circumstances, independent legal counsel
appointed by the Board of Directors in a written opinion; (iii) stockholders
of the Company; or (iv) a court of competent jurisdiction in a final,
nonappealable adjudication, that the officer or director acted in good faith
and in a manner he or she reasonably believed to be in or not opposed to the
best interests of the Company and, with respect to any criminal Proceeding,
the officer or director acted in good faith and in a manner he or she
reasonably believed to be in or not opposed to the best interests of the
Company, and the officer or director had no reasonable cause to believe that
his or her conduct was unlawful.
 
  The Placement Agency Agreement (Exhibit 1.1 hereto) provides for
indemnification by the Placement Agents of the Company, its directors and
executive officers, and each person, if any, who controls the Company, for
certain liabilities, including liabilities arising under the Securities Act.

ITEM 17. UNDERTAKINGS
 
  Insofar 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 Commission such indemnification is against public
policy as expressed in the Securities Act and is, therefore, unenforceable. If
a claim for indemnification against such liability (other than the payment by
the Company of expenses incurred or paid by a director, officer or controlling
person of the Company 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 Company 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 Company 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 Company pursuant to Rule 424(b)(1) or (4) or
  497(h) under the Securities Act shall be deemed to be part of this
  registration statement as of the time it was declared effective.
 
                                      II-4
<PAGE>
 
    (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.
 
  The Company hereby undertakes to provide at the closing specified in the
Placement Agency Agreement certificates in such denominations and registered
in such names as required by the Placement Agents to permit prompt delivery to
each purchaser.

a best efforts basis, in connection with the issuance and sale by the Company of
the Shares to the Investors. As compensation for services rendered, on the first
business day following the Closing Date, the Company shall pay to the Placement
Agents, by wire transfer of immediately available funds to an account or
accounts designated by the Placement Agents, an amount equal to 5.5% of the
gross proceeds received by the Company from the sale of the Shares at a price of

     2.   Delivery and Payment.
          -------------------- 

          (a)  On or before the third business day following the date on which

          (b)  On the Closing Date, the Company shall cause its transfer agent,
through the Depository Trust Corporation ("DTC"), to credit "free of payment"

Investors has not credited payment in full to the Nominee Account by the Closing
Date (or such later date as the Company and the Placement Agent may agree), the
Robertson, Stephens & Company LLC shall, through DTC, cause such Shares to be
returned to the Company's transfer agent. The Placement Agents shall have no
liability to the Company for any Purchased Shares credited to the Nominee
Account for which payment of the purchase price for such Shares is not, in turn,
credited to the Nominee Account as long as such Shares are returned to the
Company's transfer agent through DTC.

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 Company's obligation to reimburse the
Placement Agents 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 Placement Agents shall promptly return such payment to the Company

proceeding described in Section 7(b) hereof, they will reimburse the Company on

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 Placement
Agents' obligation to reimburse the Company 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 shall
promptly return such payment to the Placement Agents 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 within thirty (30) days
of a
                                     -18-
<PAGE>

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

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

               (vii)    The Company has the corporate power and authority to
     enter into this Agreement and to issue, sell and deliver to the Investors
     the Shares to be issued and sold by it hereunder.

               (viii)   This Agreement has been duly authorized by all necessary
     corporate action on the part of the Company and has been duly executed and
     delivered by the Company and, assuming due authorization, execution and
     delivery by you, is a valid and binding agreement of the Company,
     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 laws pertaining to bankruptcy, insolvency, fraudulent
     conveyance or transfer, equitable subordination, reorganization, moratorium
     or similar laws and judicial decisions affecting creditors' rights
     generally or by general principles of equity and public policy, including,
     without limitation, concepts of materiality, reasonableness, good faith and
     fair dealing, and except that the remedies of specific performance and
     injunctive relief may be granted or denied in the discretion of a court.

               (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
     which such counsel need express no opinion), as of the effective date of
     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 terms and provisions of the capital stock of the
     Company conform in all material respects to the description thereof
     contained in the Registration Statement and Prospectus under the caption
     "Description of Capital Stock"; and the form of certificates evidencing the
     Common Stock and filed as an exhibit to the Registration Statement is in
     due and proper form and complies with the requirements of Delaware law.

               (xii)    The descriptions in the Registration Statement and the
     Prospectus of statutes, legal and governmental proceedings, contracts and
     other documents, insofar as such statements constitute a summary of
     documents referred to therein or matters of law, are accurate summaries and
     correctly present in all

                                     -21-
<PAGE>
 
     material respects the information required to be presented by the Act and
     the applicable Rules and Regulations.

               (xiii)   To such counsel's knowledge, there are no agreements,
     contracts, leases or documents to which the Company is a party of a
     character required to be described or referred to in the Registration
     Statement or Prospectus or to be filed as an exhibit to the Registration
     Statement which are not described or referred to therein or filed as
     required.

               (xiv)    The performance of this Agreement and the consummation
     of the transactions herein contemplated (other than performance of the
     Company's indemnification obligations hereunder, concerning which no
     opinion need be expressed) will not (a) result in any violation of the
     Company's charter or bylaws or (b) to such counsel's knowledge, result in a
     material breach or violation of any of the terms and provisions of, or
     constitute a default under, any material bond, debenture, note or other
     evidence of indebtedness, or any lease, contract, indenture, mortgage, deed
     of trust, loan agreement, joint venture or other agreement or instrument to
     which the Company or any of its subsidiaries is a party or by which their
     respective properties are bound, or any applicable statute, rule or
     regulation, or any order, writ or decree of any court, government or
     governmental agency or body having jurisdiction over the Company or any of
     its subsidiaries or over any of their respective properties or operations
     (other than state securities or Blue Sky laws, concerning which no opinion
     need be expressed).

               (xv)     No consent, approval, authorization or order of or
     qualification with any court, government or governmental agency or body
     having jurisdiction over the Company or any of its subsidiaries or over any
     of their respective properties or operations is necessary in connection
     with the consummation by the Company of the transactions herein
     contemplated, except such as have been obtained under the Act or such as
     may be required under state or other securities or Blue Sky laws in
     connection with the placement of the Shares by the Placement Agents.

               (xvi)    To such counsel's knowledge, there are no legal or
     governmental proceedings pending or threatened against the Company or any
     of its subsidiaries of a character required to be disclosed in the
     Registration Statement or the Prospectus by the Act or the Rules and
     Regulations, other than those described therein.

               (xvii)   To such counsel's knowledge, neither the Company nor any
     of its subsidiaries is presently (a) in material violation of its
     respective charter or bylaws, or (b) in material breach of any applicable
     statute, rule or regulation or any order, writ or decree of any court or
     governmental agency or body having jurisdiction over the Company or any of
     its subsidiaries or over any of their respective properties or operations.

                                     -22-
<PAGE>
 
               (xviii)  To such counsel's knowledge, except as set forth in the
     Registration Statement and Prospectus, no holders of Common Stock or other
     securities of the Company have registration rights with respect to
     securities of the Company and, except as set forth in the Registration
     Statement and Prospectus, all holders of securities of the Company having
     rights to registration of shares of Common Stock or other securities,
     because of the filing of the Registration Statement by the Company have,
     with respect to the offering contemplated thereby, waived such rights or
     such rights have expired by reason of lapse of time following notification
     of the Company's intent to file the Registration Statement or have included
     securities in the Registration Statement pursuant to the exercise of and in
     full satisfaction of such rights.

               (xix)   Neither the Company nor any of its subsidiaries is, nor
     will the Company or any of its subsidiaries become upon the sale of the
     Shares and the application of the proceeds therefrom as described in the
     Prospectus under the caption "Use of Proceeds," an "investment company" or
     a person controlled by an "investment company" within the meaning of the
     1940 Act.

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

          In addition, such counsel shall state that such counsel has
participated in conferences with officials and other representatives of the
Company, the Placement Agents, Placement Agents' 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 are not passing upon and do not assume
responsibility for the accuracy, completeness or fairness of the statements
contained in the Registration Statement or the Prospectus (except as
specifically provided above), 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, 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 and other financial or statistical
data, 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, the Registration Statement, the Prospectus and any amendment
or supplement thereto (except as aforesaid) contained any untrue statement of a
material fact

                                     -23-
<PAGE>
 
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 Illinois and
Delaware upon opinions of local counsel, and as to questions of fact upon
representations or certificates of officers of the Company, 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 and to
Placement Agents' Counsel.

          (e)  You shall have received on the Closing Date an opinion of Alston
& Bird, 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 a letter from KPMG
Peat Marwick LLP addressed to the Company and the Placement Agents, dated the
Closing Date, 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 (i) confirming, to the extent
true, that the statements and conclusions set forth in the Original Letter are
accurate as of the Closing Date 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 judgment, is material and adverse and that makes
it, in your 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 Placement
Agents in form and substance satisfactory to the Placement Agents 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 sheets of the Company
as of December 31, 1995 and 1994 and related consolidated statements of
operations, stockholders' equity, and cash flows for each of the years in the
three-year period ended December 31, 1995, (iii) state that KPMG Peat Marwick
LLP has performed the

                                     -24-
<PAGE>
 
procedure 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 the six month
periods ended June 30, 1995 and 1995, and (iv) address other matters agreed upon
by KPMG Peat Marwick LLP and you.

          (f)  You shall have received on the Closing Date a certificate of the
Company, dated the Closing Date, 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,
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;

               (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 or the Exchange Act and the applicable
rules and regulations of the Commission thereunder, as the case may be, and in
all material respects conformed to the requirements of the Act and the Rules and
Regulations or the Exchange Act and the applicable rules and regulations of the
Commission thereunder, as the case may be, 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 supplement thereto, did not and does not
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, and, since the effective date of the
Registration Statement, there has occurred no event required to be set forth in
an amended supplemented Prospectus which has not been so set forth;

               (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 prospects of the Company, (b) any
transaction that is material to the Company, except transactions entered into in
the ordinary course of business, (c) any obligation, direct or contingent, that
is material to the Company, incurred by the Company, except obligations incurred
in the ordinary course of business, (d) any change in the capital stock or
outstanding indebtedness of the Company that is material to the Company, (e) any
dividend or distribution of any kind declared, paid or made on the capital stock
of the

                                     -25-
<PAGE>
 
Company, or (f) any loss or damage (whether or not insured) to the property of
the Company which has been sustained or will have been sustained which has a
material adverse effect on the condition (financial or otherwise), earnings,
exemptions, business or business prospects of the Company; and

               (v)      The Shares have been approved for listing on the Nasdaq
National Market.

          (g)  The Company shall have obtained and delivered to you an agreement
from each executive officer and director of the Company [AND EACH PERSON
IDENTIFIED ONSCHEDULE B HERETO] in writing prior to the date hereof that such
person will not, during the Lock-up Period, effect the Disposition of any
Securities now owned or hereafter acquired by such person, directly or
indirectly, or with respect to which such person has or hereafter acquires the
power of disposition, directly or indirectly, other 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 limited partners or stockholders of
such person, provided that the distributees thereof agree in writing to be bound
by the terms of this restriction, (iii) if such person is an individual, to a
member or members of his or her immediate family or to a trust the beneficiaries
of which are exclusively such person and/or a member or members of his or her
immediate family, provided that each transferee thereof agrees in writing to be
bound by the terms of this restriction, or (iv) with the prior written consent
of Robertson, Stephens & Company LLC. As to the trustee of the 401(k) Plan, such
trustee shall have delivered to you an agreement in writing prior to the date
hereof that such trustee will not, during the Lock-up Period, effect a
Disposition of any Securities now owned or hereafter acquired by such trustee,
directly or indirectly, for the benefit of the participants in the ESOP or with
respect to which such trustee has or hereafter acquires the power of
disposition, directly or indirectly, for the benefit of the participants in the
401(k) Plan; other than (i) pursuant to a valid distribution to a 401(k) Plan
participant that is required by the terms and conditions of the 401(k) Plan,
(ii) pursuant to a private sale not effected through a securities broker or
dealer or through the Nasdaq National Market, provided that the purchaser
thereof agrees in writing to be bound by the terms of this restriction, or (iii)
during any period there is outstanding a tender offer that is subject to Section
14(d)(1) of the Exchange Act. The foregoing restrictions are 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 include, without limitation, any short sale
(whether or not against the box) or any purchase, sale or grant of any right
(including, without limitation, any put or call option) with respect to any
Securities or with respect to any security (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 the foregoing restrictions.

                                     -26-

          (i)  The Company shall have furnished to you such further certificates
and documents as you shall reasonably request (including certificates of
officers of the Company) as to the accuracy of the representations and
warranties of the Company herein, as to the Performance by the Company of its
obligations hereunder and as to the other conditions concurrent and precedent to
the obligations of the Placement Agents hereunder.

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

     7.   Indemnification and Contribution.
          
          (a)  The Company agrees to indemnify and hold harmless each of the
Placement Agents against any losses, claims, damages or liabilities, joint or
several, to which either of them may become subject under the Act, the Exchange
Act or otherwise, specifically including, but not limited to, losses, claims,
damages or liabilities, insofar as such losses, claims, damages or liabilities
(or actions in respect thereof) arise out of or are 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 of the Placement Agents for
any legal or other expenses reasonably incurred by either of them 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 the
Placement Agents furnished to the Company by the Placement Agents, directly or
through you, specifically for use in the preparation thereof and, provided
further, that the indemnity agreement provided in this Section 7(a) with respect
to any Preliminary Prospectus shall not inure to the benefit of the Placement
Agents with respect to any Investor 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 who 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 4(d) hereof.

                                     -27-
<PAGE>
 
          The indemnity agreement in this Section 7(a) shall extend upon the
same terms and conditions to, and shall inure to the benefit of, each person, if
any, who controls either of the Placement Agents 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)  The Placement Agents agree severally and not jointly to indemnify
and hold harmless the Company against any losses, claims, damages or
liabilities to which the Company may become subject under the Act or otherwise,
specifically including, but not limited to, losses, claims, damages or
liabilities, insofar as such losses, claims, damages or liabilities (or actions
in respect thereof) arise out of or are based upon (i) any breach of any
representation, warranty, agreement or covenant of such Placement Agent 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 7(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 Placement Agent specifically for
use in the preparation thereof, and agrees to reimburse the Company for any
legal or other expenses reasonably incurred by the Company in connection with
investigating or defending any such loss, claim, damage, liability or action.

          The indemnity agreement in this Section 7(b) 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, and each person, if any, who controls the Company within the meaning of
the Act or the Exchange Act. This indemnity agreement shall be in addition to
any liabilities which the Placement Agents may otherwise have.

          (c)  Promptly after receipt by an indemnified party under this Section
7 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 7, notify the indemnifying party in writing of the commencement
thereof, but the omission to so notify the indemnifying party will not relieve
it from any liability which it may have to any indemnified party under this
Section 7 (except to the extent that such omission materially and adversely
affects the indemnifying party's ability to defend such action) or from any
liability otherwise than under this Section 7. 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

                                     -28-
<PAGE>
 
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 received a written opinion from counsel 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 7 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 7(a)
or 7(b) 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 claims that are the subject
matter of such proceeding.

          (d)  In order to provide for just and equitable contribution in any
action in which a claim for indemnification is made pursuant to this Section 7
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 7 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, except as set forth
in Section 7(e) hereof, the Placement Agents severally and not jointly are
responsible pro rata for the portion represented by the percentage that the
Placement Agents' fee bears to the gross proceeds received by the Company
(before deducting the Placement Agents' fee), and the Company is responsible for
the remaining portion, provided, however, that no person guilty of a fraudulent

                                     -29-
<PAGE>
 
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 7(d) shall extend
upon the same terms and conditions to, and shall inure to the benefit of, each
person, if any, who controls either Placement Agent or the Company 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. This
subsection (d) shall not be operative as to any Placement Agent to the extent
that the Company is entitled to receive or has received indemnity from such
Placement Agent under this Section 7.

          (e)  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 7, and are fully informed regarding said provisions.
They further acknowledge that the provisions of this Section 7 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. The parties are advised that federal or state public policy as interpreted
by the courts in certain jurisdictions, may be contrary to certain of the
provisions of this Section 7, and the parties hereto hereby expressly waive and
relinquish any right or ability to assert such public policy as a defense to a
claim under this Section 7 and further agree not to attempt to assert any such

Registration Statement and the form of Placement Agency Agreement filed with the
Commission as an exhibit to the Registration Statement (the "Placement Agency

such further investigations as we have deemed necessary to enable us to express
the opinion hereinafter set forth.

     We hereby advise you that in our opinion the Shares have been duly
authorized by the Company and, upon payment and delivery in accordance with the
Placement Agency Agreement, will be validly issued, fully paid and
nonassessable.

Registration Statement and to the reference to us under the caption "Legal
Matters" in the Registration Statement.  In giving this consent, we do not
hereby admit that we are in the category of persons whose consent is required
under Section 7 of the Securities Act of 1933 or the rules and regulations of
the Securities and Exchange Commission.

written verification of receipt.

SECTION 8.    PROTECTIVE COVENANTS.  The Associate acknowledges and agrees that
solely by virtue of his employment by, and relationship with, the Employer, he
will acquire "Confidential Information," as hereinafter defined, as well as
special knowledge of the Employer's relationships with its customers and
business brokers, and that, but for his association with the Employer, the
Associate will not have access to said Confidential Information or knowledge of
said relationships. The Associate further acknowledges and agrees (i) that the
Employer has long term, near-permanent relationships with its customers

                                       2
<PAGE>
 
and business brokers, and that those relationships were developed at great
expense and difficulty to the Employer over several years of close and
continuing involvement; (ii) that the Employer's relationships with its
customers and business brokers are and will continue to be valuable, special and
unique assets of the Employer and that the identity of its customers and
business brokers is kept under tight security with the Employer and cannot be
readily ascertained from publicly available materials available to the
Employer's competitors; and (iii) that the Employer has the following
protectable interests that are critical to its competitive advantage in the
industry and would be of demonstrable value in the hands of a competitor:
software designs, including but not limited to designs relating to health care
materials management, health care operating room management, health care patient
cost accounting, health care capital asset management, and health care
centralized patient scheduling; plans; processes and protocols; formulae; and
concepts, ideas and other matters not known to the general public. In return for
the consideration, the receipt and sufficiency of which are hereby acknowledged,
and as a condition precedent to the Employer entering into this Agreement, and
as an inducement to the Employer to do so, the Associate hereby represents,
warrants, and covenants as follows:

     A.   The Associate has executed and delivered this Agreement as his free
     voluntary act, after having determined that the provisions contained herein
     are of material benefit to him, and that the duties and obligations imposed
     on him hereunder are fair and reasonable and will not prevent him from
     earning a comparable livelihood following the termination of his employment
     with the Employer;

     B.   The Associate has read and fully understands the terms and conditions
     set forth herein, has had time to reflect on and consider the benefits and
     consequences of entering into this Agreement, and has had the opportunity
     to review the terms hereof with an attorney or other representative, if he
     so chooses;

     C.   The execution and delivery of this Agreement by the Associate does not
     conflict with, or result in a breach of or constitute a default under, any
     agreement or contract, whether oral or written, to which the Associate may
     be bound;

     D.   The Associate agrees that, during the time of his employment and for a
     period of one (1) year after termination of the Associate's employment
     hereunder for any reason whatsoever or for no reason, whether voluntary or
     involuntary, the Associate will not, except on behalf of Employer:

          (1)  directly or indirectly, contact, solicit or direct any person,
          firm, or Corporation to contact or solicit any of the Employer's
          customers, prospective customers, or business brokers (as hereinafter
          defined) for the purpose of selling or attempting to sell, any
          products and/or services that are the same as or similar to the
          products and services provided by the Employer to its customers during
          the term hereof. In addition, the Associate will not disclose the
          identity of any such business brokers, customers, or prospective
<PAGE>
 
          customers, or any part thereof, to any person, firm, corporation,
          association, or other entity for any reason or purpose whatsoever, and

          (2)  directly or indirectly, whether as an investor (excluding
          investments representing less than five percent (5%) of the common
          stock of a public company), lender, owner, stockholder, officer,
          director, consultant, employee, agent, salesperson or in any other
          capacity, whether part-time or full-time, become associated with any
          business involved in the design, manufacture, marketing, or servicing
          of products then constituting ten percent (10%) or more of the annual
          sales of the Employer; and

          (3)  solicit or accept if offered to him, with or without
          solicitation, on his own behalf or on behalf of any other person, the
          services of any person who is an associate of the Employer, nor
          solicit any of the Employer's associates to terminate employment with
          the Employer; and

          (4)  act as a consultant, advisor, officer, manager, agent, director,
          partner, independent contractor, owner, or employee for or on behalf
          of any of the Employer's business brokers, customers, or prospective
          customers (as hereinafter defined), with respect to or in any way with
          regard to any aspect of the Employer's business and/or any other
          business activities in which Employer engages during the term hereof.

     E.   The Associate acknowledges and agrees that the scope described above
     is necessary and reasonable in order to protect the Employer in the conduct
     of its business and that, if the Associate becomes employed by another
     employer, he shall be required to disclose the existence of this Paragraph
     8 to such employer.

     F.   For purposes of this Paragraph 8, "customer" shall be defined as any
     person, firm, or entity that purchased any type of product and/or service
     from Employer or is or was doing business with the Employer or the
     Associate within the twelve (12) month period immediately preceding
     termination of the Associate's employment. For purposes of this Paragraph
     8, "prospective customer" shall be defined as any person, firm, or entity
     contracted or solicited by the Employer or the Associate (whether directly
     or indirectly) or who contacted the Employer or the Associate (whether
     directly or indirectly) within the twelve (12) month period immediately
     preceding termination of the Associate's employment for the purpose of
     having such persons, firms, or entities become a customer of the Employer.
     For purposes of this Paragraph 8, "business broker" shall be defined as any
     person, firm, or entity who is or was doing business with the Employer or
     the Associate who was contacted or solicited by the Employer or the
     Associate (whether directly or indirectly) or who contacted or solicited
     the Employer or the Associate (whether directly or indirectly) within the
     twelve (12) month period immediately preceding termination of the
     Associate's employment.

                                       4

     G.   The Associate agrees that both during his employment and thereafter
     the Associate will not, for any reason whatsoever, use for himself or
     disclose to any person not employed by the Employer any "Confidential
     Information" of the Employer acquired by the Associate during his
     relationship with the Employer, both prior to and during the term of this
     Agreement. The Associate further agrees to use Confidential Information
     solely for the purpose of performing duties with the Employer and further
     agrees not to use Confidential Information for his own private use or
     commercial purposes or in any way detrimental to the Employer. The
     Associate agrees that "Confidential Information" includes but is not
     limited to: (a) any financial, business, planning, software, operations,
     services, potential services, products, potential products, designs,
     technical information and/or know-how, formulas, production, purchasing,
     marketing, sales, personnel, customer, broker, supplier, or other
     information of the Employer; (b) any papers, data, records, processes,
     methods, techniques, systems, models, samples, devices, equipment,
     compilations, invoices, customer lists, or documents of the Employer; (c)
     any confidential information or trade secrets of any third party provided
     to the Employer in confidence or subject to other use or disclosure
     restrictions or limitations; and (d) any other information, written, oral,
     or electronic, whether existing now or at some time in the future, whether
     pertaining to current or future developments, and whether previously
     accessed during the Associate's tenure with the Employer or to be accessed
     during his future employment with the Employer, which pertains to the
     Employer's affairs or interests or with whom or how the Employer does
     business. The Employer acknowledges and agrees that Confidential
     Information does not include (i) information properly in the public domain,
     or (ii) information in the Associate's possession prior to the date of his
     original employment with the Employer.

     H.   During and after the term of employment hereunder, the Associate will
     not remove from the Employer's premises any documents, records, files,
     notebooks, correspondence, computer printouts, computer programs, computer
     software, price lists, microfilm, or other similar documents containing
     Confidential Information, including copies thereof, whether prepared by him
     or others, except as his duty shall require, and in such cases, will
     promptly return such items to the Employer. Upon termination of his
     employment with the Employer, all such items including summaries or copies
     thereof, then in the Associate's possession, shall be returned to the
     Employer immediately. The Associate agrees to return of such items, which
     shall be a requirement in order for the Associate to receive, at the time
     of such termination, or any time thereafter, any compensation due him
     pursuant to any paragraphs hereunder or otherwise.

     I.   The Associate recognizes and agrees that all ideas, inventions,
     enhancements, plans, writings, and other developments or improvements (the
     "Inventions") conceived by the Associate, alone or with others, during the
     term of his employment, whether or not during working hours, that are
     within the scope of the Employer's business operations or that relate to
     any of the Employer's work or projects, are the sole and exclusive property
     of the Employer. The Associate further agrees that (a) he

                                       5
<PAGE>
 
     will promptly disclose all Inventions to the Employer and hereby assigns to
     the Employer all present and future rights he has or may have in those
     Inventions, including without limitation those relating to patent,
     copyright, trademark or trade secrets; and (b) all of the Inventions
     eligible under the copyright laws are "work made for hire." At the request
     of and without charge to the Employer, the Associate will do all things
     deemed by the Employer to be reasonably necessary to perfect title to the
     Inventions in the Employer and to assist in obtaining for the Employer such
     patents, copyrights or other protection as may be provided under law and
     desired by the Employer, including but not limited to executing and signing
     any and all relevant applications, assignments or other instruments.
     Notwithstanding the foregoing, pursuant to the Employee Patent Act,
     Illinois Public Act 83-493, the Employer hereby notifies the Associate that
     the provisions of this Paragraph 8 shall not apply to any Inventions for
     which no equipment, supplies, facility or trade secret information of the
     Employer was used and which were developed entirely on the Associate's own
     time, unless (a) the Invention relates (i) to the business of the Employer,
     or (ii) to actual or demonstrably anticipated research or development of
     the Employer, or (b) the Invention results from any work performed by the
     Associate for the Employer.

     J.   The Associate acknowledges and agrees that all customer lists,
     supplier lists, and customer and supplier information, including, without
     limitation, addresses and telephone numbers, are and shall remain the
     exclusive property of the Employer, regardless of whether such information
     was developed, purchased, acquired, or otherwise obtained by the Employer
     or the Associate. The Associate agrees to furnish to the Employer on demand
     at any time during the term of this Agreement, and upon termination of this
     Agreement, his complete list of the correct names and places of business
     and telephone numbers of all of its customers served by him and located
     within any and or all of the territories to which he has been assigned,
     including all copies thereof wherever located. The Associate further agrees
     to immediately notify the Employer of the name and address of any new
     customer, and report all changes of location of old customers, so that upon
     the termination of this Agreement, the Employer will have a complete list
     of the correct names and addresses of all of its customers with which the
     Associate has had dealings. The Associate also agrees to furnish to the
     Employer on demand at any time during the term of this Agreement, and upon
     the termination of this Agreement, any other records, notes, computer
     printouts, computer programs, computer software, price lists, microfilm, or
     any other documents related to the Employer's business, including originals
     and copies thereof; and

     K.   It is agreed that any breach or anticipated or threatened breach of
     any of the Associate's covenants contained in this Paragraph 8 will result
     in irreparable harm and continuing damages to the Employer and its business
     and that the Employer's remedy at law for any such breach or anticipated or
     threatened breach will be inadequate and, accordingly, in addition to any
     and all other remedies that may be available to the Employer at law or in
     equity in such event, any court of competent jurisdiction may issue a
     decree of specific performance or issue a temporary and permanent
     injunction, without providing special damages or irreparable injury,

                                       6
<PAGE>
 
          enjoining and restricting the breach, or threatened breach, of any
          such covenant, including, but not limited to, any injunction
          restraining the Associate from disclosing, in whole or in part, any
          Confidential Information. The Associate acknowledges the truthfulness
          of all factual statements in this Agreement and agrees that he is
          estopped from and will not make any factual statement in any
          proceeding that is contrary to this Agreement or any part thereof. The
          Associate further agrees to pay all of the Employer's costs and
          expenses, including reasonable attorneys' fees and accountants' fees,
          incurred in enforcing such covenants.

SECTION 9.  TERMINATION.  The Corporation shall have the right to discharge
Associate at any time. Unless otherwise stated under SECTION 2 of this
Agreement, or as defined hereafter:

               Revolving Loan; provided, however, that such notice is received
               by the Bank not later than 2:00 p.m. on the Banking Day on which
               the Borrower is requesting the Revolving Loan be made available
               by the Bank in the case of a Revolving Loan to bear interest at
               the Floating Rate and not later than two (2) Banking Days prior
               to the Banking Day on which the Borrower is requesting the
               Revolving Loan be made available by the Bank in the case of a
               Revolving Loan to bear interest at the LIBOR-

               Based Rate.  Each and every request for a Revolving Loan shall
               constitute Borrower's representation and warranty that (i) as of
               the date of said request, no Event of Default (or event which,
               with the giving of notice or lapse of time or both, would
               constitute an Event of Default) has occurred and is continuing,
               (ii) no material adverse change has occurred in the operations or
               financial condition of the Borrower since the date of the most
               recent fiscal quarter for which the Borrower's Financial
               Statements have been delivered to the Bank and received thereby,
               subject to Bank's reasonable discretion to determine whether such
               a material adverse change has occurred, (iii) the representations
               and warranties of the Borrower set forth within Article IV are
               true and correct as of the date of the request for a Revolving
               Loan, (iv) the affirmative and negative covenants set forth in
               Article V are not currently being breached and are inviolate as
               of the date of such request for a Revolving Loan, and (v) the
               aggregate Revolving Loans, including the Revolving Loan
               requested, do not exceed the Revolving Loan Commitment.

     2.2  The Borrower's Loan Account.  The Bank shall maintain a loan account
          ("Loan Account") on its books in which shall be recorded (i) the Loans
          made by the Bank to the Borrower pursuant to this Agreement, (ii) all
          payments made by the Borrower on the Loans, and (iii) all other
          appropriate debits and credits as provided in this Agreement, the Loan
          Supporting Documents or the Note, including, without limitation, all
          fees, charges, expenses and interest provided for hereunder or
          thereunder.  All advances to the Borrower and all other debits and
          credits provided for in this Agreement or the Note, shall be evidenced
          by entries made by the Bank in its internal data control systems, in
          accordance with the Bank's customary accounting practices as in effect
          from time to time, showing the date, amount and reason for each such
          debit or credit.  The Bank shall send the Borrower statements of all
          amounts due hereunder as reflected in the Loan Account, which
          statements shall be considered presumptively correct as to the
          indebtedness due and owing by the Borrower to the Bank unless the
          Borrower notifies the Bank within one hundred twenty (120) days of
          receipt of such statement that the Borrower considers such statement
          to be incorrect and the Borrower specifically identifies the items on
          such statement which it considers to be incorrect and attaches any
          evidence in its possession supporting its position.

     2.3  Interest Rate; Payments.
          ----------------------- 

  2.3 (a) The Revolving Loans; Rate.   Each Revolving Loan shall bear
          interest at the Borrower's option at either of the following
          rates:  (i) the Prime Rate less one-half of one percent (1/2%),
          computed on the basis of actual days elapsed over a 360-day year
          (the "Floating Rate"); or (ii) a fixed interest rate per annum
          (computed for the actual number of days elapsed on the basis of 

                                      -9-
<PAGE>
 
          a 360-day year) which shall be equal to the LIBOR-Based Rate in
          effect on the date the Bank quotes such rate to the Borrower (the
          "LIBOR-Based Rate").  The Borrower's acceptance of any LIBOR-
          Based Rate shall be final and conclusive as to all matters with
          respect to the determination thereof.  Interest on Loans bearing
          interest at the Floating Rate shall be payable monthly in arrears
          beginning on June 30, 1996, and continuing on the last day of
          each calendar month thereafter.  The Floating Rate shall
          fluctuate concurrently with and in an amount equal to any
          increase or decrease in the Prime Rate. Interest on Loans bearing
          interest at the LIBOR-Based Rate shall be payable in
          arrears on the last day of the applicable LIBOR Rate Borrowing
          Period.

 2.3 (b)  Interest Rate Election. Borrower shall make an election in writing
          pursuant to Section 2.1 (c) as to whether such Revolving Loan shall
          bear interest at the Floating Rate or the LIBOR-Based Rate. If
          Borrower elects to have a Revolving Loan bear interest at the LIBOR-
          Based Rate, Borrower shall also specify the applicable LIBOR Rate
          Borrowing Period for such Revolving Loan; provided, however, no more
          than eight (8) Revolving Loans may bear interest at the LIBOR-Based
          Rate at any time and each Revolving Loan bearing interest at the 
          LIBOR-Based Rate shall be in a minimum amount of $500,000.

 2.3 (c)  Borrowing Periods. At any time when the Borrower shall select or renew
          the LIBOR-Based Rate to apply to any Revolving Loan, it shall fix a
          period for each such Revolving Loan during which such LIBOR-Based Rate
          shall apply, such periods to be for periods (the "LIBOR Rate Borrowing
          Periods") of 30, 60, 90 and 180 days; provided that (i) in no event
          shall any LIBOR Rate Borrowing Period so selected expire later than
          the Revolving Loan Termination Date; and (ii) if any LIBOR Rate
          Borrowing Period expires on a day which is not a Banking Day, such
          LIBOR Rate Borrowing Period shall expire on the next Banking Day.

 2.3 (d)  Conversion to LIBOR-Based Rate. Upon two (2) Banking Days prior
          written or telephonic notice to Bank, Borrower may elect to convert
          any Revolving Loan bearing interest at the Floating Rate into a
          Revolving Loan bearing interest at the LIBOR-Based Rate in effect on
          the date of the election. Borrower shall, in such notice, specify the
          LIBOR Borrowing Rate Period for such LIBOR-Based Revolving Loan. Upon
          such election, Bank shall make a notation on its books and records
          evidencing such conversion.

 2.3 (e)  Renewal of Interest Rate Option. Upon the expiration of any LIBOR Rate
          Borrowing Period, the Borrower may renew the LIBOR-Based Rate for one
          or more additional LIBOR Rate Borrowing Periods; provided that
          Borrower shall give to the Bank notice of the renewal date in
          accordance with the provisions of Section 2.3(b) hereof. In 

                                      -10-
<PAGE>
 
          the absence of the receipt of a notice from the Borrower of renewal in
          accordance with this Section 2.3(e) or of conversion in accordance
          with Section 2.3(d), the interest rate with respect to any such
          Revolving Loan as to which such notice is not properly received shall
          automatically be converted to the Floating Rate on the last day of the
          expiring LIBOR Rate Borrowing Period.

 2.3 (f)  LIBOR Rate Unascertainable; Impracticability.  The Bank shall
          promptly notify the Borrower in the event that:

          (i)  on any date on which a LIBOR-Based Rate selected by the Borrower
               by notice to the Bank would otherwise be set (including any
               conversion to or renewal thereof), the Bank shall have determined
               in good faith (which determination shall be final and conclusive)
               that adequate and reasonable means do not exist for determining
               the LIBOR Rate; or

          (ii) at any time the Bank shall have determined in its reasonable
               business judgment (which determination shall be final and
               conclusive) that the selection of a LIBOR-Based Rate or the
               continuation of or the conversion or renewal of a LIBOR-Based
               Rate has been made impossible or impracticable or unlawful by
               compliance by Bank with any applicable law or governmental
               regulation, guideline or order or interpretation thereof by any
               governmental authority charged with the interpretation or
               administration thereof or with any request or directive of any
               such governmental authority (whether or not having the force of
               law).

 2.3 (g)  Effect of Unascertainability or Impractibility. Once the Bank has
          given notice of its determination under (i) or (ii) above, the
          obligation of the Bank to allow conversion to or selection or renewal
          of the LIBOR-Based Rate by the Borrower with respect to any Revolving
          Loan shall be suspended until the Bank gives further notice to the
          Borrower that the selection of a LIBOR-Based Rate or the continuation
          of or the conversion or renewal of a LIBOR-Based Rate is no longer
          impossible or impracticable or unlawful. If the Bank has determined in
          accordance with (ii) above that it may no longer continue any LIBOR
          Rate Revolving Loans, then upon the date specified in any notice of
          determination under (ii) above (which shall not be earlier than the
          date such notice is given), (x) the LIBOR-Based Rate shall cease to
          apply and any Revolving Loans bearing interest at the LIBOR-Based Rate
          shall automatically be converted to the Floating Rate and (y) the
          Borrower shall pay to Bank the accrued and unpaid interest on any
          Revolving Loans bearing interest at the LIBOR-Based Rate to (but not
          including) such
                                      -11-
<PAGE>
 
               specified date. If, at the time notice of a determination is
               given pursuant to this Section 2.3(g), the Borrower has
               previously been offered the LIBOR-Based Rate by the Bank and has
               previously notified the Bank that it wishes to convert to or
               select or renew the LIBOR-Based Rate, but such rate has not yet
               been set, such notification shall be of no force and effect, and
               the Borrower shall, with respect to any Revolving Loan subject to
               such notice, either (i) convert such Revolving Loan to the
               Floating Rate or (ii) if such Revolving Loan is bearing interest
               at the Floating Rate, retain the Floating Rate as to such
               Revolving Loan.

     2.3 (h)   Indemnity.  Without prejudice to any other provision of this
               Agreement, the Borrower shall compensate the Bank upon written
               request by the Bank for all losses (including, but not limited
               to, lost profits) and expenses in respect of any interest paid by
               the Bank to lenders of funds borrowed by the Bank or deposited
               with the Bank to make or maintain any of the Revolving Loans
               which accrue interest at the LIBOR-Based Rate, which the Bank may
               sustain (i) if for any reason not due to an error or omission by
               Bank, a borrowing to which the LIBOR-Based Rate is to apply does
               not occur on a date specified therefor hereof; (ii) if any
               prepayment or repayment of any of the Revolving Loans bearing
               interest at the LIBOR-Based Rate occurs on a date which is not
               the last date of the relevant LIBOR Rate Borrowing Period; (iii)
               as a consequence of any Event of Default by the Borrower under
               this Loan Agreement or any acceleration or mandatory prepayment
               or principal reduction.  Without limiting the generality of the
               foregoing, the Borrower shall indemnify the Bank against any loss
               or expense which the Bank may sustain or incur as a consequence
               of the default by the Borrower in payment of principal of or
               interest on any Revolving Loan bearing interest at the LIBOR-
               Based Rate, including, but not limited to, any premium or penalty
               incurred by the Bank in respect of funds borrowed by it or
               deposited with it for the purpose of making or maintaining any of
               the Revolving Loans, as determined by the Bank in the exercise of
               its sole discretion.  A certificate submitted by the Bank to the
               Borrower shall, in the absence of error, be conclusive and
               binding as to the amount thereof.

     2.3 (i)   Discretion of Bank as to Manner of Funding.  Notwithstanding any
               other provision of this Agreement, Bank shall be entitled to fund
               and maintain its funding of all or any part of its Revolving
               Loans in any manner it sees fit, it being understood, however,
               that for purposes of this Agreement all determinations hereunder
               shall be made as if Bank had actually funded and maintained each
               Loan bearing interest at the LIBOR-Based Rate through the
               purchase of deposits in the interbank market having a maturity
               corresponding to such Loan bearing interest at the LIBOR-Based
               Rate and

                                      -12-
<PAGE>
 
               bearing an interest rate equal to the LIBOR-Based Rate for such
               LIBOR Rate Borrowing Period.

     2.4      Fees and Expenses.
              ----------------- 

     2.4 (a)  Unused Line Fee.  The Borrower shall pay to the Bank an unused
              line fee of 18.75 basis points per annum on the daily average of
              the unused amount of the Revolving Loan Commitment. Such unused
              line fee shall be payable quarterly in arrears on the last day of
              each calendar quarter commencing with the quarter ending June 30,
              1996.

     2.4 (b)  Expenses.  The Borrower shall reimburse the Bank for all its
              expenses incurred in connection with the preparation,
              negotiation, documentation, amendment, modification,
              administration or enforcement of this Agreement, the Note or any
              Loan Supporting Documents, including reasonable attorney and
              paralegal fees.

     2.5      Optional Prepayment.  The Borrower may, upon same day written
              notice, prepay in whole or in part, at any time and from time to
              time, without premium or penalty, the principal, accrued interest
              and all other amounts of any Revolving Loans bearing interest at
              the Floating Rate. The Borrower may from time to time prepay
              Revolving Loans bearing interest at the LIBOR-Based Rate; however,
              the Borrower shall pay to the Bank an amount equal to the amount
              of interest which the Bank would have earned for the balance of
              such LIBOR Rate Borrowing Period in respect of the Revolving Loan
              so prepaid if such Revolving Loan had not been prepaid prior to
              the end of such LIBOR Rate Borrowing Period, plus any reasonable
              expense or penalty incurred by Bank on so relending or reinvesting
              such Revolving Loan, reduced, if Bank is able to relend or
              reinvest the principal amount of the Revolving Loan so prepaid for
              the balance of such LIBOR Rate Borrowing Period, by the amount of
              interest to Bank on so relending or reinvesting the Revolving
              Loan. Such additional payment shall not exceed the difference
              between the amount of interest the Bank would have earned for the
              balance of such LIBOR Rate Borrowing Period in respect of the
              Revolving Loan so prepaid if such Revolving Loan had originally
              been made at the Floating Rate in effect as of the date of the
              prepayment, plus any reasonable expenses incurred by Bank on so
              relending or reinvesting such Revolving Loan.

     2.6      Application of Payments and Prepayments. Any payments made by the
              Borrower under this Agreement, the Note or any of the other Loan
              Supporting Documents shall be applied to Obligations owing as of
              the date of payment in the following order: (i) to any amounts
              owing to the Bank pursuant to Sections 2.7 and 5.1(j) of this
              Agreement;
               
                                      -13-
<PAGE>
 
              (ii) regard to interest accrued pursuant to the terms of the Note;
              and (iii) to the principal balance of the Loans.

     2.7      Default Interest.  In the event any amount of principal or
              interest due hereunder or any other payment due under this
              Agreement or any of the other Loan Documents becomes overdue, such
              overdue amount shall accrue interest at the Default Interest Rate
              from twenty-four hours after receipt of notice thereof from Bank
              through the date of payment.

     2.8      Service Charges.  Borrower acknowledges that Bank will charge
              Borrower monthly service charges for various services performed by
              Bank, which service charges have been provided to the Borrower
              from the Bank and shall be updated from time to time by Bank, in
              connection with the Loans and/or other aspects of the relationship
              between Borrower and Bank, and Borrower hereby agrees with Bank
              that if such service charges arising in any one month exceed the
              credit to Borrower in that month arising from earnings
              attributable to funds on deposit with Bank in demand deposit
              accounts, such service charge deficiency shall be charged by Bank
              against Borrower's operating account.

     2.9      Payment to the Bank.  All sums payable to the Bank hereunder shall
              be paid directly to the Bank, at the address set forth in Section
              8.8, in immediately available funds. With the prior consent of
              Borrower or after the occurrence of an Event of Default, the Bank,
              in its sole discretion, may charge against or debit any deposit
              account of the Borrower all or any part of any amount due
              hereunder or under the Note. Any check, draft or similar item of
              payment by or for the account of Borrower delivered to the Bank on
              account of the Obligations shall, provided the same is honored and
              final settlement is reflected by irrevocable credit to Bank, be
              applied on account of Borrower's Obligations on the date of final
              settlement. The Bank's right from time to time after the
              occurrence or happening of an Event of Default hereunder (which
              has not been waived in a writing signed by the Bank) to setoff
              indebtedness owing by the Borrower to the Bank against the
              Borrower's monies, deposits, credits, accounts or other property
              now or at any time in the possession or control of the Bank, is
              hereby acknowledged and agreed to by the Borrower.

              Borrower to the Bank shall constitute separate and distinct
              conditions precedent to the making of any additional Loans by the
              Bank to the Borrower:

     3.1 (a)  A duly executed copy of this Agreement;

full, regardless of any investigation by the Bank of the Borrower's financial
condition or assets:

          failure to obtain such consent, approval or authorization or to make
          such filing, registration or qualification would have a material
          adverse effect on the condition or operations of Borrower, Borrower's
          Property or Borrower's ability to perform the Obligations, or, if so
          required, has been duly obtained or effected before the date hereof.

               (ii) the violation or contravention of, the occurrence of a
                    default, event of default or event, which with the passage

                    Incorporation or bylaws of the Borrower or any Affiliates,
                    any certificates of authority to do or transact business,

          their terms and provisions (except as enforcement thereof may be
          subject to applicable bankruptcy, insolvency, moratorium or similar
          laws affecting creditors' rights generally and to general principles
          of equity) and, on the date of delivery, the Borrower will not be in
          violation or contravention of, and no Event of Default will exist
          under, any of the foregoing.

     4.4  Default of Indebtedness.  The Borrower is not in default and no Event
          of Default or event, which with the passage of time or giving of
          notice or both, 

                                      -17-

          fully and fairly present the financial condition of the Borrower as at

          received thereby, no material adverse change in the Borrower's
          financial condition or affairs has occurred and no dividends on or

          Affiliates which could materially adversely affect the assets,

          good and marketable title to all of its Property and assets, including

          possession of Borrower's salesmen from time to time; (c) all Inventory
          is presently owned and will continue to be owned by the Borrower,
          except as otherwise permitted pursuant to the terms of this Agreement,

          the validity, amount or imposition of the above while maintaining
          accounting reserves on the books of Borrower in an amount not less
          than the maximum potential liability of Borrower, and such contest
          does not have or cause a material adverse change in the Borrower's
          financial condition or operations and does not impair the Borrower's
          ability to perform its Obligations, has made adequate provision for
          the payment of all taxes, assessments, penalties, interest and other

          issued in connection with the above shall provide that said policies

<PAGE>
 
          required if an Event of Default has occurred and is continuing), but

          applicable present and future Laws unless the Borrower is contesting
          in good faith, by an appropriate proceeding, the validity, amount or
          imposition of the above, while maintaining reserves to cover the above
          which are adequate in accordance with prudent business practices, and
          such contest does not have or cause a material adverse change in the
          Borrower's financial condition or operations and does not impair
          Borrower's ability to perform its Obligations.  In the event
          the Borrower fails to pay any such taxes, assessments, charges or
          levies, the Bank may, without waiving or releasing any of Borrower's
          Obligations or any Event of Default hereunder, pay the same upon
          notice to Borrower (which notice shall not be required if an Event of
          Default shall have occurred and be continuing), but shall be under no
          obligation to do so.  All sums so paid by the Bank and any expenses
          incurred in connection therewith shall be part of the Obligations
          payable by the Borrower to the Bank on demand pursuant to Section
          5.1(j) hereof.

          maintenance to the foregoing and all rentals or mortgage payments on
          the foregoing, and in the event the Borrower fails in the foregoing,
          the Borrower hereby authorizes, without requiring the Bank, to perform
          the same and to incur such reasonable costs,

          such financial information concerning the Borrower's Property or

          relating to the this Agreement and the Loan Supporting Documents,
          except where it is determined that Bank's action or failure to act
          constituted gross negligence or willful misconduct.

          the Bank and hold the Bank harmless from any and all claims, demands,
          liabilities, losses, damages, diminutions of value, costs and expenses
          relating to or in any way arising out of or from this Agreement, the
          Loan Supporting Documents and/or the Loans, except as the foregoing
          relate to the Bank's gross negligence, reckless or intentional
          misconduct.  The Borrower hereby releases the Bank from any and all

          effected or such Employee 

                                      -26-

          so as to prevent any default thereunder which may result in the
          exercise or enforcement of any landlord's or other lien against the
          Borrower unless (i) the Borrower is contesting in good faith, by an
          appropriate proceeding, the validity, amount or imposition of any
          lease charges or expenses while maintaining reserves to cover the
          above which are adequate in accordance with prudent business
          practices, and such contest does not have or cause material adverse
          changes in the Borrower's financial condition or operations and does
          not impair the Borrower's ability to perform the Obligations or (ii)
          the failure by Borrower to comply will not have a material adverse
          effect on such lease and Borrower's ability to occupy the premises

               whether by cash or check.  The Borrower may have unlimited access
               to the Operating Account until such time after the occurrence of
               an Event of Default as the Bank notifies the Borrower in writing
               that it intends to restrict the Borrower's access to the
               Operating Account.

          (ii) The Borrower agrees that at the Bank's option during the
               continuance of an Event of Default, all cash Funds deposited in

               Obligations on the Banking Day on which the cash Funds became

                  after which such Funds become available for deposit. The
                  Borrower agrees to pay all fees, costs and expenses which the
                  Bank incurs in connection with opening and maintaining the
                  Operating Account and depositing for collection by the Bank
                  any check or other item of payment received by the Bank on
                  account of the Borrower's Obligations. All of such fees, costs
                  and expenses shall be payable to the Bank by the Borrower upon
                  demand, and, until paid, shall bear interest at the rate then
                  applicable hereunder. All checks, drafts, instruments and
                  other items of payment shall be endorsed by the Borrower to
                  the Bank, and, if that endorsement of any such items shall not
                  be made for any reason, the Bank is hereby irrevocably
                  authorized to endorse the same on the Borrower's behalf.

            (iii) The Borrower will maintain all its primary depository and
                  disbursement banking accounts at the Bank and shall be

account of Borrower's Liabilities or any guaranty thereof. Bank shall have no 
obligation to protect, secure or insure any of the foregoing security interests,
liens or encumbrances or the properties or interests in properties subject 
thereto. Guarantor's Liabilities shall in no way be impaired, affected, reduced

Guaranty shall not, by the lapse of time, the giving of notice or otherwise, 
conflict with or result in a breach of the Certificate of Incorporation or 
Bylaws of Guarantor or constitute a violation of any provision of applicable 
law, or contained in any agreement, instrument or document

                                      -2-

to which Guarantor is now or may hereafter become a party or by which Guarantor
is or may become bound.

     (F) Guarantor is now and at all times hereafter, shall be solvent and
generally able to pay its debts as such debts become due and Guarantor now owns

Guarantor's knowledge, threatened against Guarantor which might result in any
material and adverse change in Guarantor's financial condition or materially
affect Guarantor's ability to perform Guarantor's Liabilities.

enforceability of any security interests of any kind or nature granted by
Borrower to Bank.

relating to Borrower's ability to pay and perform Borrower's Liabilities.

further acknowledges and agrees that in executing this Guaranty and at all times
hereafter, Guarantor has relied and will continue to rely upon Guarantor's own

and Guarantor has not and will not hereafter rely upon Bank for any such
information or facts.

exercise of prudent business practices believes are or were due and payable,
unless Guarantor is contesting in good faith, by an appropriate proceeding, the

Borrower.

     (C) Guarantor waives, but only in favor of Bank, any and all rights of

Liabilities, or against or with respect to the Borrower's property (including,
without limitation, property collateralizing Borrower's Liabilities), arising
from the existence or performance of this Guaranty until all of Borrower's
Liabilities are paid in full.

     (D) Guarantor waives any right to assert against Bank as a defense,
counterclaim, setoff or crossclaim to the payment or performance of Guarantor's
Liabilities, any defense (legal or equitable), setoff, counterclaim or claim
which Guarantor may now or at any time or times hereafter have against Borrower
or any other party liable to Bank in any way or manner with respect to
Borrower's Liabilities.

     (E) Guarantor hereby waives notice of the following events or occurrences
and agrees that Bank may do any or all of the following in such manner, upon
such terms and at such times as Bank in its sole discretion deems advisable
without in any way impairing, affecting, reducing or releasing Guarantor from
Guarantor's Liabilities:  (i) Bank's acceptance of this Guaranty; (ii) Bank's
heretofore, now or from time to time hereafter loaning monies or giving or
extending credit to or for the benefit of Borrower, whether pursuant to the Loan
Agreements or any amendments, modifications or additions thereto or alterations
or substitutions made heretofore, now or at any time or times hereafter; (iii)
Borrower's heretofore, now or at any time or times hereafter granting to Bank
security interests, liens or encumbrances in any of Borrower's assets or Bank's
heretofore, now or from time to time hereafter obtaining, substituting for,
releasing, waiving or modifying any 

                                      -6-
<PAGE>
 
such security interests, liens or encumbrances; (iv) Bank's heretofore, now or
at any time or times hereafter obtaining, releasing, waiving or modifying of any
other party's guaranty of Borrower's Liabilities or any security interest, lien
or encumbrance in any other party's assets given to Bank to secure such party's
guaranty of Borrower's Liabilities; (v) Bank's heretofore, now or at any time or
times hereafter obtaining, amending, substituting for, releasing, waiving or
modifying any of the Loan Agreements; (vi) presentment, demand, notices of

to Bank on account of Borrower's Liabilities) of any indulgences or extensions
of time of payment of Borrower's Liabilities; and (viii) Bank's heretofore, now
or at any time or times hereafter accepting from Borrower or any other party any
partial payment or payments on account of Borrower's Liabilities or any
collateral securing the payment thereof or Bank's settling, subordinating,
compromising, discharging or releasing the same.

          6.   Subordination.  Guarantor covenants and agrees with Bank that:
(a) all indebtedness, liability or liabilities owed and at any time or times
hereafter owing by Borrower to Guarantor are hereby subordinated to Borrower's
Liabilities; (b) all security interests, liens and encumbrances which Guarantor

indebtedness, liability or liabilities now and at any time or times hereafter
owing to Guarantor by any party liable to Bank by reason of any security

Bank.

Liabilities.  Regardless of the adequacy of any Collateral securing Guarantor's
Liabilities hereunder, any deposits or other sums at any time credited by or
payable or due from Bank to Guarantor, or any monies, cash, cash equivalents,
securities, instruments, documents or other assets of Guarantor in possession or

successors and assigns.  Written notice to Guarantor shall be to the address or
addresses specified below.

          Bank's failure at any time hereafter to require strict performance by
Guarantor of any provision of this Guaranty shall not waive, effect or diminish
any right of Bank thereafter to demand strict compliance and performance
therewith.

                             AMENDMENT TO GUARANTY

     This Amendment to Guaranty is made as of May 31, 1996 by and between
Enterprise Systems, Inc. (formerly known as Enterprise Systems International,
Inc.), a Delaware corporation ("GUARANTOR") and LaSalle National Bank ("BANK"),
has reference to the following facts and circumstances.

     WHEREAS, Guarantor has made a guaranty in favor of Bank dated as of May 31,
1996 (the "GUARANTY") with respect to financial accommodations made by Bank to
Enterprise Systems, Inc., an Illinois corporation; and

     WHEREAS, Guarantor and Bank desire to amend the Guaranty to correct an
ambiguity contained therein.

     Now Therefore, in consideration of the foregoing Recitals, each of which is
made a part hereof, the parties hereby delete the first paragraph in Section
4(D) of the Guaranty and substitute the following therefor:

          (D)  THE GUARANTOR SHALL NOT (I) CHANGE ITS CORPORATE NAME OR ADOPT AN
     ASSUMED CORPORATE NAME WITHOUT PROVIDING THE BANK PRIOR WRITTEN NOTICE, AND
     SUCH NAME CHANGE SHALL BE DONE IN COMPLIANCE WITH ANY APPLICABLE LAWS, (II)
     CONSOLIDATE OR MERGE WITH ANY PERSON, WITHOUT THE PRIOR WRITTEN CONSENT OF
     BANK, WHICH CONSENT SHALL NOT BE UNREASONABLY WITHHELD, (III) AT ANY TIME
     THAT THE OUTSTANDING PRINCIPAL BALANCE UNDER THE LOAN AGREEMENT IS
     $9,000,00 OR MORE, ISSUE SHARES OF STOCK IN A NEW PUBLIC OFFERING, WITHOUT
     THE PRIOR CONSENT OF BANK WHICH CONSENT SHALL NOT BE UNREASONABLY WITHHELD,
     OR (IV) ACQUIRE ANY STOCK IN, OR OTHERWISE ACQUIRE ALL OR SUBSTANTIALLY ALL
     OF THE ASSETS OR PROPERTIES OF, ANY PERSON, FOR CASH OR THE ISSUANCE OR
     TRANSFER OF SHARES OF STOCK OF GUARANTOR, WITHOUT THE PRIOR WRITTEN CONSENT
     OF BANK, WHICH CONSENT SHALL NOT BE UNREASONABLY WITHHELD.

     The parties agree that the substitute language shall be deemed to have been
in effect from and after May 31, 1996, and the deleted text shall be void ab
initio and deemed never to have taken effect. Except as expressly amended
hereby, the Guaranty shall remain in full force and effect, unamended hereby.
Guarantor hereby reaffirms and remakes the Guaranty as of the date hereof, as if
fully set forth herein. From and after the date hereof, all references to the
Guaranty in the Guaranty and the other Loan Documents, shall mean the Guaranty,
as amended hereby.

     This Agreement may be signed in one or more counterparts, each of which
shall be an original, but all of which together shall constitute one agreement,
binding on all of the parties hereto notwithstanding that all of the parties
hereto are not signatories to the same counterpart. For purposes of negotiating
and finalizing this Agreement (including any subsequent amendments thereto), any
signed document transmitted by facsimile machine ("FAX") shall be treated in all
manner and respects as an original document. The signature of any party by FAX
shall be considered for these purposes as an original signature. Any such FAX
document shall 




<PAGE>
 

be considered to have the same binding legal effect as an original document. At
the request of either party, any FAX document subject to this Agreement shall be
re-executed by both parties in an original form. The undersigned parties hereby
agree that neither shall raise the use of the FAX or the fact that any signature
or document was transmitted or communicated through the use of a FAX as a
defense to the formation of this Agreement.

     Guarantor of Bank have executed this Amendment as of the date set forth
herein.

                              Enterprise Systems, Inc.

applicable laws (including, without limitation, compliance with the health care

and each applicable ERISA Affiliate have received favorable determination
letters as to the qualification under the Code of each pension plan, as defined
in Section 3(2) of ERISA ("PENSION PLAN"), and there have been no amendments or
other developments since the date of such determination letters which would
cause the loss of such qualified status.  No violation of ERISA has at any time
occurred in connection with the administration of any of the Plans, and there
are no actions, suits, or claims (other than routine, non-contested claims for
benefits) pending or, to the knowledge of Company or Stockholder, threatened
against the Plans, or any administrator or fiduciary thereof, which could result
in any liability.

     4.16.(c) Neither Company nor any ERISA Affiliate nor any of their
employees, stockholders, or directors have engaged in any transaction in
connection with which any of them would be subject either to civil penalty
assessed pursuant to Section 502 of ERISA or a tax imposed by Section 4975 of

412 of the Code), whether or not waived, exists with respect to any Plan, nor
has there been any lien imposed under Section 412(n) of the Code. The execution

otherwise) becoming due to any employee of Company or any ERISA Affiliate of
Company.

         4.18.(a) Schedule 4.18.(a) contains a complete list (other than items

description by category and indication of status (completed or in process) of
all Patents, Trademarks, Software and Licenses-In which are owned, licensed by,
licensed to, used or held for use in the Matkon Business as such Matkon Business
is currently conducted (other than "off the shelf" software, the license fees
for which are immaterial), or as to which Company has a contractual right.

         4.18.(b) The rights of Company in and to each item of the Intellectual
Property other than Intellectual Property subject to Licenses-In ("OWNED
INTELLECTUAL PROPERTY") are owned outright by Company, free and clear of any
security interests. Except as set forth on Schedule 4.18(a) all of Company's
rights in and to such Intellectual Property are freely assignable in its own
name, including the right to create derivatives, and Company is under no
obligation to pay any royalty or other compensation to any third party or to
obtain any approval or consent for use of any of the Owned Intellectual
Property. None of the Owned Intellectual Property is subject to any outstanding
judgment, order, decree, stipulation, injunction or charge; no charge,
complaint, action, suit, proceeding, hearing, investigation, claim, or demand is
pending or, to the knowledge of Company or Stockholder, threatened, which
challenges the legality, validity, enforceability, use or ownership of any of
the Owned Intellectual Property; and, except pursuant to the Licenses-Out,
Company has never agreed to indemnify any person for or against any
interference, infringement, misappropriation, or other conflict with respect to
Owned Intellectual Property.

         4.18.(c) No material breach or default (or event which with notice or
lapse of time or both would result in a material breach or default) by Company
exists under any License-In or other agreement pursuant to which Company uses
any Intellectual Property, and, subject to obtaining any necessary consents to
transfer such licenses, the consummation of the transactions contemplated by
this Agreement will not violate or conflict with or constitute a breach or
default (or an event which, with notice or lapse of time or both, would
constitute a breach or default) or result in a forfeiture under, or constitute a
basis for termination of, any such License-In or other agreement.

                                      19

         4.18.(d) Company owns or has the right to use all the Intellectual
Property necessary to provide, produce, sell and license the Software, systems,
services and products currently provided, produced, sold and licensed by the
Matkon Business, and to conduct Matkon Business as presently conducted, and,
subject to obtaining any necessary consents to the transfer of Licenses-In, the
consummation of the transactions contemplated hereby will not alter or impair
any such rights, including any right of Company to use or sublicense any
Intellectual Property owned by others. The Intellectual Property includes all
patents, trademarks, trade names, service marks, copyrights and trade secrets,
and the Software (together with the Licenses-In) includes all software, which
are necessary to operate the Matkon Business as it is presently conducted.

         4.18.(e) The Owned Intellectual Property does not infringe any
trademark, trade name, copyright, trade secret, patent, right of publicity,
right of privacy or other proprietary right of any person give rise to an
obligation to render an accounting to any person as a result of co-authorship,
co-invention or an express or implied contract for any use or transfer. Company
has received no notice of any adversely held patent, invention, trademark,
copyright, service mark, trade name or trade secret of any other person alleging
or threatening to assert that Company's use of any of the Intellectual Property
infringes upon or is in conflict with any intellectual property or proprietary
rights of any third party. Neither Company nor Stockholder has any knowledge of
any basis for any charge or claim, threatened claim or any suit or action
asserting any such infringement or conflict by the Owned Intellectual Property
or asserting that Company does not have the legal right to own, enforce, sell,
license, sublicense, lease or otherwise use any Owned Intellectual Property, and
neither Company nor Stockholder has any knowledge of any facts which should give
such person reason to believe that there exists any basis for such claim,
threatened claim or suit or that any such claim, threatened claim or suit may be
asserted or instituted in the future.

         4.18.(f) Company has not sent or otherwise communicated to any other
person any notice, charge, claim or assertion of, and neither Company nor
Stockholder has any knowledge of, any present, impending or threatened
infringement by any other person of any Owned Intellectual Property.

been issued by, registered with or filed with the United States Patent and
Trademark Office or the corresponding offices of other countries identified in
Schedule 4.18.(a) have been so duly registered, filed in or issued, as the case
may be, and have been properly maintained and renewed in accordance with all
applicable provisions of law and administrative regulations in the United States
and each such other country. Company has used reasonable efforts to protect its
rights in the Owned Intellectual Property and any related apparatus or processes
and to maintain the confidentiality of its trade secrets, know-how and other
confidential Owned Intellectual Property, and neither Company nor Stockholder is
aware of any acts or omissions, the result of which would be to


                                      20
<PAGE>
 
compromise the rights of Company to apply for or enforce appropriate legal
protection of Owned Intellectual Property.

         4.18.(h) It is the Company's policy to have each employee of the
Company hired since 1986 to sign an employee nondisclosure agreement
substantially in the form of Schedule 4.18.(h) (and all but approximately five
Matkon-related employees have executed such agreements) and Company is hereby
assigning to Buyer all of Company's rights under such agreements with respect to
the Matkon employees. No employees or independent contractors of Company have
any valid claims or rights to any of the Owned Intellectual Property. To the
knowledge of Company and Stockholder, no employee of Company is a party to or
otherwise bound by any agreement with or obligated to any other person
(including, any former employer) which in any respect conflicts with any
obligation, commitment or job responsibility of such employee to Company under
any agreement to which currently he or she is a party or otherwise.

         4.18.(i) Schedule 4.14.(a) identifies each person to whom Company has
sold, licensed, leased or otherwise transferred or granted any interest or
rights to any Owned Intellectual Property, and the date of each such sale,
license, lease or other transfer or grant. Company has previously made available
to Buyer complete and accurate copies of all documents relating to each such
sale, license, lease or other transfer or grant. Company has made available to
Buyer copies of all copyright and trademark registration certificates.

         4.18.(j) Without limiting the generality of the foregoing, Company has
never used, adopted, appropriated or disclosed to any person, and none of
Company's owned Software, systems or products incorporates, is based upon or is
derived or adapted from, or was developed using, any proprietary rights, trade
secrets, source code, intellectual property or confidential information of any
other person in violation of any statutory or common law obligation or any
agreement. In addition, Company is not in default under that certain License
Agreement between Company and Healthcare Purchasing Partner, Inc. (formerly
known as Health One) dated July 1, 1992 (the "HEALTH ONE AGREEMENT"); Company
has the right to assign its interest as set forth under the Health One
Agreement, including a nonexclusive license to use the software and the property
covered under the Health One Agreement; and neither Company nor Buyer will have
any further obligations to make royalty payments or satisfy other obligations
under the Health One Agreement.

         4.18.(k) Dealers and Distributors.  Company does not use any sales
representatives, dealers, distributors or franchisees in connection with the
Matkon Business.

contracts.  The amount of the

"Deferred Revenue" liability for the Matkon Business on the Company's May 20,
1996 balance sheet exceeds the cost (based on Company's current business
practices) of work to be performed by the Matkon Business with respect to the
Unbilled Receivables and any claims or demands of customers of the Matkon
Business outstanding on the date hereof. Schedule 4.19 lists all customers who
have terminated, canceled or allowed to expire service or maintenance agreements
for the Software during the twelve months prior to the date hereof. Except as
set forth in Schedule 4.19, the Software owned by the Company conforms,
functions and operates in all material respects in accordance with its
specifications, and neither Company nor Stockholder is aware of any defects in
the design, coding, implementation or operation of the Software owned by the
Company that would substantially impair the operation of the Software owned by
the Company. The foregoing representation shall not apply with respect to any
Software under development, including, without limitation, the accounts payable
module. The Software owned by the Company complies with all governmental
standards and specifications currently in effect.

geographical scope or activity, it is expressly agreed that this covenant not to
compete shall be construed so that the remaining provisions shall not be
affected, but shall remain in full force and effect, and any such over broad

efforts (which shall not be deemed to include providing any guarantees, deposits
or other financial assistance) to secure, on Buyer's behalf, agreements between

             (a)   Notwithstanding anything in this Agreement to the contrary,
this Agreement shall not constitute an agreement to assign or transfer any of 
the Assumed Contracts or part thereof or right or benefit arising thereunder or 
resulting therefrom if any attempted assignment or transfer thereof, without the
consent of a third party thereto, would constitute a breach thereof.  If such 
consent is not obtained, or if an attempted assignment thereof would be 
ineffective or would affect the rights of Buyer so that Buyer would not in fact 
receive all such rights, Company and Buyer (i) shall cooperate in endeavoring 
to obtain such consent promptly at no cost to either party and (ii) if any such 
consent is unobtainable, shall cooperate in any reasonable arrangement (the 
"Assignment Substitute") designed to provide Buyer the benefits under any such 
Assumed Contract or part thereof or any right or benefit arising thereunder or 
resulting therefrom, including enforcement for the benefit of Buyer of any and 
all rights of Company against a third party arising out of the breach or 
cancellation by such third party or otherwise.  Buyer shall, to the extent 
necessary, perform under the Assignment Substitute without a fee to Company 
except for the consideration to be paid under such contract.

             (b)   Notwithstanding anything in this Section 7.13 to the
contrary, if no consent to assignment is obtained for Assumed Contracts set
forth in Schedule 7.13, Company and Stockholder, jointly and severally, hereby
agree to indemnify Buyer from and against all amounts required to be refunded to
customers, and all lost profits on Unbilled Receivables relating to, such
Assumed Contracts for which no consent is obtained. With respect to Company's
contract with North Broward Hospital District, the indemnification provided for
under this paragraph 7.13(b) shall not apply if consent is denied as a result of
Buyer's failure of performance under such contract after the date hereof (other
than failure of performance solely with respect to the accounts payable module).
Upon obtaining consent to assignment of a contract, the indemnity in this
paragraph will terminate with respect to such contract.


     7.14.   Franciscan Agreement.  Company and Stockholder, jointly and 
severally, agree to indemnify Buyer from and against all amounts due and owing 
from Company (or Buyer) under the Franciscan Agreement for the provision of an 
accounts payable system from a third party provider.  Buyer agrees to use its 
reasonable efforts to attempt to convince Franciscan to accept one of Buyer's 
accounts payable modules in satisfaction of such obligation under the Franciscan
Agreement.  Buyer agrees to provide status reports related to progress under the
Franciscan Agreement at the request of the Company.

any such Claim, and the Indemnifying Party will undertake the defense thereof by
representatives chosen by it (subject to the Indemnified Party's reasonable 
approval).  The assumption of defense shall constitute an admission by the 
Indemnifying Party of its indemnification obligation hereunder with respect to 
such Claim, and its undertaking to pay directly all costs, expenses, damages,

Failure to give such notice shall not affect the Indemnifying Party's duty or

Claim actively and in good faith, shall not settle such Claim.  The Indemnified

faith, the Indemnified Party will have the right to undertake the defense,
compromise or settlement of such Claim or consent to the entry of a judgment
with respect to such Claim, on behalf of and for the account and risk of the
Indemnifying Party, and the Indemnifying Party shall thereafter have no right to
challenge the Indemnified Party's defense, compromise, settlement or consent to
judgment.

        8.3.(c)    Indemnified Party's Rights. The Indemnifying Party shall not,
without the written consent of the Indemnified Party, settle or compromise any
Claim or consent to the entry of any judgment which does not include as an
unconditional term thereof the giving by the claimant or the plaintiff to the
Indemnified Party of a release from all Liability in respect of such Claim.

     8.4.    Payment.  The Indemnifying Party shall promptly pay the Indemnified
Party any amount due under this Article 8.  Upon judgment, determination, 
settlement or compromise of any third party Claim, the Indemnifying Party shall 
pay promptly on behalf of the Indemnified Party, and/or to the Indemnified Party
in reimbursement of any


                                       29

amounts theretofore paid by it, the amount so determined by judgment,
determination, settlement or compromise and all other Claims of the Indemnified
Party with respect thereto, unless in the case of a judgment an appeal is made

judgment, then the Indemnifying Party shall post and pay the cost of the
security or bond to stay execution of the judgment pending appeal.

                          (i)  There shall be no time limitation on claims on
              actions brought for breach of any representation or warranty made
              in or pursuant to Sections 4.11(c), 4.12(a), 4.18(b), (e), and
              (j).

                          (ii)  Any claim or action brought for breach of any
              representation or warranty made in or pursuant to Section 4.5 may
              be brought at any time until the underlying tax obligation is
              barred by the applicable period of limitation under federal and
              state laws relating thereto (as such period may be extended by
              waiver).

                          (iii) Any claim made by a party hereunder by sending
              written demand to the other party specifying the nature of the
              breach prior to the termination of the survival period for such
              claim shall be preserved despite the subsequent termination of
              such survival period.

                          (iv)  If any act, omission, disclosure or failure to
              disclose shall form the basis for a claim for breach of more than
              one representation or warranty, and such claims have different
              periods of survival hereunder, the termination of the survival
              period of one claim shall not affect a party's right to make a
              claim based on the breach of representation or warranty still
              surviving.

        8.5.(b)   Amount Limitation.  Except with respect to claims for breaches
of representations or warranties contained in Sections 4.12(a), 4.18(b), (e) and
(j), 4.23, or 5.4 an Indemnified Party shall not be entitled to indemnification
under this Article 8 for breach of a representation or warranty unless the
aggregate of the Indemnifying Party's indemnification obligations to the
Indemnified Party pursuant to this Article 8 (but for this Section 8.5(b))
exceeds $100,000 but in such event, the Indemnified Party shall be entitled to
indemnification in full for all breaches of representations and/or warranties.

     10.7.   Continued Performance.  The fact that the dispute resolution 
procedures specified in this Article 10 shall have been or may be invoked shall 
not excuse any party from performing its obligations under this Agreement and 
during the pendency of any such procedure all parties shall continue to perform 
their respective obligations in good faith, subject to any rights to terminate 
this Agreement that may be available to any party.

     10.8.   Tolling. All applicable statutes of limitation shall be tolled

11.  MISCELLANEOUS

     11.1.   Further Assurance. From time to time, at Buyer's request and
without further consideration, Company and Stockholder will execute and deliver
to Buyer such documents, instruments and consents and take such other action as
Buyer may reasonably request in order to consummate more effectively the
transactions contemplated hereby, to discharge the covenants of Company and
Stockholder, and to vest in Buyer good and valid title to the Matkon Business
and Purchased Assets.

     11.2.   Disclosures and Announcements.  Both the timing and the content of
all disclosure to third parties and public announcements concerning the 
transactions provided for in this Agreement by either Company or Buyer shall be 
subject to the approval of the other in all essential respects, except that the 
Company's approval shall not be required as to any statements and other 
information which Buyer may submit to the Securities and Exchange Commission, 
the Nasdaq Stock Market, Inc. or Buyer's Stockholders or be required to make 
pursuant to any rule or regulation of the Securities and Exchange Commission or 
the Nasdaq Stock Market, Inc., or otherwise required by law.  Company hereby 
agrees to provide its consent, which may not be unreasonably withheld, to 
Buyer's presentation of pro forma financial information related to Buyer's 
acquisition of the Matkon Business, as may be required under the securities 
laws, rules and regulations of the Securities and Exchange Commission.

     11.3.   Assignment; Parties in Interest. 

        11.3.(a)  Assignment. Except as expressly provided herein, the rights
and obligations of a party hereunder may not be assigned, transferred or
encumbered without the prior written consent of the other parties.
Notwithstanding the foregoing, Buyer may, without consent of any other party,
cause one or more subsidiaries of Buyer to carry out all or part of the
transactions contemplated hereby; provided, however, that Buyer shall,
nevertheless, remain liable for all of its obligations, and those of any such
subsidiary, to Company hereunder. In addition, Buyer may assign this agreement
in connection with the transfer or sale of substantially its entire business to
which this Agreement pertains or

                                       34
<PAGE>
 
in the event of its merger or consolidation with another entity, provided Buyer
will remain liable under this Agreement.

        11.3.(b)   Parties in Interest. This Agreement shall be binding upon,
inure to the benefit of, and be enforceable by the respective successors and
permitted assigns of the parties hereto. Nothing contained herein shall be
deemed to confer upon any other person any right or remedy under or by reason of
this Agreement.

     11.4.   Equitable Relief.  Company and each Stockholder agree that any 
breach by Company or any stockholder of its or their obligations imposed by 
Sections 7.6 hereof, will result in irreparable injury to Buyer for which a 
remedy at law would be inadequate; and that, in addition to any relief at law 
which may be available to Buyer for such breach and regardless of any other 
provision contained in this Agreement, Buyer shall be entitled to injunctive and
other equitable relief as a court may grant.  This Section 11.4 shall not be 
construed to limit Buyer's and Company's right to obtain equitable relief for 
other breaches of this Agreement under general equitable standards.

     11.5.   Law Governing Agreement.  This Agreement shall be construed and 
interpreted according to the internal laws of the State of Illinois, excluding 
any choice of law rules that may direct the application of the laws of another 
jurisdiction.  Process and pleadings mailed to a party at the address provided 
in Section 11.7 shall be deemed properly served and accepted for all purposes.

                 specifications of FLEXIEnhancements no later than
                 April 30, 1996.  On or before May 15, 1996, FLEXI

                 FLEXI shall enhance FlexiFinancials and shall
                 develop and incorporate the agreed upon subset of
                 FLEXIEnhancements described in Exhibit 3.1.1 and
                 shall use commercially reasonable efforts to
                 deliver FlexiFinancials (with such

                 the described FLEXIEnhancement specifications on
                 or before October 1, 1996. FLEXI agrees to use
                 reasonable efforts to deliver the remaining
                 FLEXIEnhancements as part of its first year
                 commitment of development resources as provided in

                 on or embodied in such suitable medium as mutually
                 agreed by the parties.  FLEXI also agrees to
                 deliver Documentation for such FLEXIEnhancements

                 and agents.  To the extent such enhancements are
                 omitted from the Documentation, FLEXI shall
                 provide materials in order for ESi to draft the
                 applicable documentation.  FLEXI, in its own
                 discretion, shall determine the manner and means
                 for developing the FLEXIEnhancements and preparing
                 the Documentation, which includes the
                 FLEXIEnhancements, as provided above.

          In the event FLEXI fails to deliver any FlexiFinancials (with the
                 agreed upon subset of FLEXIEnhancements) or not substantially
                 deliver the agreed upon FLEXIEnhancements on or before October

                 per month for each full calendar month of delay not to exceed
                 three (3) months.

                 Should FLEXI not deliver any of the agreed upon
                         FLEXIEnhancements within 120 days after October 1,
                         1996, January 28, 1997 ("Trigger Date"), ESi may
                         terminate this Agreement with no further obligations
                         between the parties, except those provisions that
                         survive termination. Upon such termination, ESi shall
                         receive a full refund of the Royalty Payments and the
                         Payments and Exclusivity Payments provided in Sections
                         9.1 and 9.3, to the extent such payments have been made
                         to FLEXI

                 Should FLEXI not substantially deliver the agreed upon
                         FLEXIEnhancements within 120 days after October 1,
                         1996, January 29, 1997 ("Trigger Date"), ESi may
                         terminate this Agreement with no further obligations
                         between the parties, except those provisions that
                         survive termination. Upon such termination, ESi shall

                     Payments and the Payments and Exclusivity Payments provided
                     in Sections 9.1 and 9.3, to the extent such payments have
                     been made to FLEXI less $150,000.

               Section 3.1.2.1 and Section 3.1.2.2 state the entire liability of
                     FLEXI with respect to FLEXI's failure to deliver the
                     FLEXIEnhancements as provided in Section 3.1.1.

          It is understood and agreed that changes to the agreed upon
                   specifications subset of FLEXIEnhancements, or any changes to
                   the specifications for FLEXIEnhancements, or any additional
                   work not specified, or follow-on work shall be made only upon
                   written agreement as provided in Section 0, which shall
                   result in the expiration of ESi's option to terminate this
                   Agreement as provided in Section 3.1.2.1 and Section 3.1.2.2.
                   In addition, ESi's failure to notify FLEXI in writing of its
                   exercise of the option to terminate this Agreement as
                   provided in Section 3.1.2.1 and Section 3.1.2.2 within thirty
                   (30) business days after the Trigger Date shall result in
                   ESi's waiver of its option to terminate as provided in
                   Section 3.1.2.1 and Section 3.1.2.2 and such termination
                   option shall expire. Upon expiration or termination of ESi's
                   option to terminate this Agreement as provided in Section
                   3.1.2.1 and Section 3.1.2.2, ESi's sole and exclusive remedy
                   shall be as for FLEXI to correct Errors as provided in
                   Section 3.3.

     Progress Review; Acceptance FLEXIEnhancements.  During the development of
             the FLEXIEnhancements under this Agreement, ESI and FLEXI
             shall meet as mutually agreed at the offices of FLEXI to
             assess progress on FLEXIEnhancements.  Within thirty (30)
             days of delivery of the agreed upon subset of
             FLEXIEnhancements to ESi, or sixty (60) days thereafter if
             ESi delivers FlexiFinancials containing FLEXIEnhancements to
             an End User prior to the end of the thirty (30) day period,
             ESI shall determine in good faith whether or not there is
             Acceptance of FlexiFinancials containing FLEXIEnhancements.
             ESi shall notify FLEXI of its Acceptance or rejection due to
             Errors of FlexiFinancials as provided in Exhibit 3.1.1;
             should ESI fail to notify FLEXI of its Acceptance on or
             before the end of such period, FlexiFinancials containing
             FLEXIEnhancements shall be deemed accepted.  Should ESi
             reject FlexiFinancials, ESi shall provide a report
             describing in detail the basis for such rejection and
             providing information in order for FLEXI to reproduce the
             Error(s) in the FLEXIEnhancements.  Upon request, ESi shall
             provide such additional information for FLEXI to reproduce
             such Errors.  Failure to provide information or FLEXI's
             failure to reproduce such Errors shall result in the
             Acceptance of FlexiFinancials.  Upon FLEXI's confirmation of
             Errors, ESi's sole and exclusive remedy shall be for FLEXI
             to correct such Errors as provided in Section 3.3.

     Joint Testing; Correction of Error.  ESi shall use commercially reasonable
             efforts to test the delivered FLEXIEnhancements as incorporated
             within FlexiFinancials at ESi's headquarters or at FLEXI's
             headquarters. FLEXI shall use commercially reasonable efforts to
             correct in a timely manner material Errors identified during such
             testing as provided in Section 4.3.

                   FLEXIEnhancements") to FlexiFinancials as mutually agreed
                   by FLEXI and ESi. To the extent such enhancements are not
                   prepared as part of FLEXI's development resource
                   commitment specified in Section 4.2.1, FLEXI shall propose
                   reasonable additional compensation for such enhancements.

          General Enhancements; Extra Cost Options.  FLEXI shall advise ESi as
               to its plans for preparation of any General Enhancements, which
               shall mean Enhancements prepared and/or licensed for additional
               compensation ("Extra Cost Options") or prepared and/or licensed

               and licensed for no additional compensation to existing FLEXI
               licensees.  If ESi elects to obtain Extra Cost Options, FLEXI
               shall propose reasonable additional compensation for such
               enhancements.

          ESi and FLEXI agree to modify this Agreement to reflect the parties'
               understanding with respect to General Enhancements or Additional
               FLEXIEnhancements.  Upon such modification of this Agreement, the
               General Enhancements or Additional FLEXIEnhancements shall become
               part of FlexiFinancials and FlexiFinancials Documentation.  Under
               no circumstances shall FLEXI be obligated to undertake any Extra
               Cost Options or Additional FLEXIEnhancements without a written
               agreement between the parties.

               FLEXIEnhancements that are requested by ESi and mutually agreed
               upon by the parties, subject in both instances to FLEXI's
               development methodology and development schedules. During the
               second calendar year following Acceptance, FLEXI agrees to
               provide twenty (20) man-weeks of development resources for
               Additional FLEXIEnhancements, subject to FLEXI's development
               methodology and development schedules and ESi agrees to pay to
               FLEXI at least $41,000, which payment may be based upon a credit
               for any Maintenance and Enhancement Fees paid pursuant to Section
               9.10.2 in the second year. For the third and fourth calendar
               year, to the extent ESi paid to FLEXI at least $41,000 in
               Maintenance and Enhancement Fees, FLEXI agrees to provide ESi

                              man-weeks for each $10,000 in Maintenance and
                              Enhancement Fees in excess of $41,000, subject to
                              FLEXI's development methodology and development
                              schedules.

     Error Correction Services.  Subject to Section 4.2, should there occur an
                    Error in FlexiFinancials during the term of this Agreement,
                    and ESI notifies FLEXI in writing of the Error in sufficient
                    detail for FLEXI to reproduce such Error, FLEXI shall
                    provide at FLEXI's expense commercially reasonable
                    correction services to resolve the Error ("Error Correction
                    Services"), provided the Error is not the result of any
                    change or modifications in FlexiFinancials made by ESI or
                    any of its End-Users.  FLEXI may furnish Error Correction
                    Services in any format that resolves the Error, including,
                    but not limited to, Product Temporary Fix ("PTF") format,
                    until such time as such correction can be conveniently
                    incorporated into the generally available release of
                    FlexiFinancials or the associated documentation.

     Source Code Escrow.  FLEXI agrees to deposit a copy of the Source Code of
                    FlexiFinancials with an escrow agent ("Escrow Agent") and
                    agrees to notify ESI of the Escrow Agent. FLEXI shall update
                    the Source Code with each Release as designated by FLEXI and
                    maintain such release in escrow.

                    In the event (a) FLEXI has filed a petition in bankruptcy,
                              or has made a general assignment for the benefit
                              of creditors or has had a receiver appointed for
                              all or substantially all of its business, or has
                              been liquidated or dissolved, (b) the institution
                              of bankruptcy, receivership, insolvency,
                              reorganization or other similar proceedings
                              against FLEXI under the Federal Bankruptcy Code or
                              any state court receivership proceedings, if such
                              proceedings have not been dismissed or discharged
                              within ninety (90) days after they are instituted,
                              or (c) a final adjudication of FLEXI as bankrupt
                              and, in each such case, FLEXI (its successor and
                              assigns) fails to continue to support the then
                              current release of the FlexiFinancials, ESI will,
                              upon payment of the duplication cost and other
                              handling charges of the Escrow Agent, be entitled
                              to obtain a copy of the Source Code of            
                              FlexiFinancials from the Escrow Agent as long as
                              ESI is current with all its obligations to FLEXI
                              and licensed to use said release of 
                              FlexiFinancials. ESI will, however, only use the
                              Source Code of FlexiFinancials to maintain
                              ESiFinancials as provided in this Agreement.

                    Attached hereto in Exhibit 4.4.2 is a form of escrow
                              agreement, "Preferred Escrow Agreement," to be
                              executed by Data Securities International, Inc.,
                              FLEXI's Escrow Agent, and FLEXI and ESi. Licensee
                              understands that the Preferred Escrow Agreement is
                              subject to the approval of the Escrow Agent. ESi
                              agrees to pay all fees and reasonable expenses of
                              the Escrow Agent imposed upon FLEXI in connection
                              with the Preferred Escrow Agreement or substitute
                              thereto. It is FLEXI's understanding that the
                              Escrow Agent's current fees are $2,300 with a
                              renewal fee on each anniversary of $1,300 and that
                              the Escrow Agent's current facility for notices
                              and deposit materials is: Data Securities
                              International, Inc., 9555 Chesapeake Drive, Suite
                              200, San Diego, CA 92123. ESi understands and
                              agrees that such fees are subject to determination
                              by the Escrow Agent."

RESPONSIBILITIES OF ESI

     Development Assistance.  ESI shall provide to FLEXI certain information and
                    software as determined by the parties and all other
                    information and technical support that is necessary for
                    FLEXI to create and maintain FLEXIEnhancements ("ESI
                    Information").  ESI shall deliver to FLEXI ESI Information
                    in a form mutually agreed upon by the parties.  A listing of
                    such ESI Information shall be provided to FLEXI upon the
                    delivery of such information and incorporated by reference
                    as Exhibit 0.  After delivery of 

                                       6
<PAGE>
 
          FlexiFinancials, FLEXI shall retain copies of the ESI Information
          while this Agreement is in effect, for use in the maintenance of
          FlexiFinancials as provided pursuant to Section O. FLEXI shall return
          to ESI or destroy all copies of such ESI Information as long as ESI
          and FLEXI have no further continuing obligations as provided in
          Section O (except such information provided to FLEXI under normal
          commercial terms and conditions) upon termination of this Agreement.

     Dedicated Client Workstation.  During the term of this Agreement, ESI shall
          dedicate a client workstation as reasonably specified by FLEXI solely
          for use for FlexiFinancials and ESiFinancials.  ESI acknowledges and
          agrees that FLEXI may provide technical support and perform other
          services for ESI through the dedicated client workstation (or through
          such other means as the parties mutually agree) and, therefore, access
          to FlexiFinancials or ESiFinancials as the case may be through the
          dedicated client workstation and telecommunications facilities must be
          maintained.  Should ESI fail to maintain such dedicated client
          workstation or telecommunications facilities access, FLEXI may impose
          additional fees for technical support.

     Designated ESI Personnel.  ESI shall designate an ESI project manager and
          technical support specialist at its own expense to work with FLEXI in
          determining the specifications and test criteria, and to work with
          FLEXI during the course of the development of the FLEXIEnhancements.
          From time to time and as agreed by the parties, ESI further agrees to
          provide such other staff at its own expense to assist FLEXI.
          Notwithstanding ESi's assistance, FLEXI shall retain responsibility
          for overall project management resulting in the development of the
          FLEXIEnhancements and FlexiFinancials.

     ESI Accounting for Royalties; Reporting.  ESI shall maintain detailed and
          accurate records with respect to License-Related Gross Revenues and
          such other revenue that is the basis for payments to FLEXI and shall
          pay to FLEXI royalties as set forth in Section O.  ESI shall within
          thirty (30) days after the end of each calendar month send to FLEXI a
          statement identifying the End User and showing the number of copies of
          ESiFinancials, FlexiFinancials, and Third Party Software licensed by
          it during that month, the License-Related Gross Revenues of such
          licenses as invoiced by FLEXI, and the Royalty Payments in respect of
          such sales and Support Fees and Maintenance and Enhancement Fees to
          which FLEXI is entitled pursuant to Section O and Section 9.10 hereof.
          ESI shall keep separate and accurate records in respect of all
          licenses of the ESiFinancials, FlexiFinancials, and Third Party
          Software made by it during the term of this Agreement and for three
          (3) years thereafter, and shall permit FLEXI or its authorized agent
          to inspect all such records and make copies thereof for FLEXI's own
          use as provided in Section O hereof.

     Inspection and Audit.  FLEXI, or any agent authorized by FLEXI, shall have
          the right at all reasonable times upon seven (7) days prior written
          notice, and in any event no more than semiannually (or as often as
          FLEXI determines necessary if an audit reveals that actual Royalty
          Payments with respect to any quarter were less than ninety percent
          (90%) of the Royalty Payments paid by ESi), to inspect ESi's
          facilities and audit ESi's relevant books, records and any other
          relevant information at ESi's offices in order to determine whether
          ESI is in compliance with the terms and conditions of this Agreement.
          ESI agrees to reasonably cooperate and provide all reasonably
          necessary documentation to enable FLEXI or its agent to conduct such
          audit, including, but not limited to, providing the Source Code,
          Object Code, and Executable Code of ESiModifications and
          ESiFinancials.  Should any such audit reveal that actual Royalty
          Payments with respect to any quarter were less than ninety percent
          (90%) of the Royalty Payments paid by ESI to FLEXI for such quarter,
          ESI shall, in addition to paying all fees and expenses associated with
          the audit, remit to FLEXI the amount of the unpaid Royalty Payments or
          in the case two or more quarters within a four quarter period reveal
          that actual Royalty Payments were less 

                                       7
<PAGE>
 
          than ninety percent (90%), payment of twice the amount of the unpaid
          Royalty Payments, and in each case interest as provided in Section 0
          hereof.

     ESI Compliance with Laws.  ESI agrees to comply with all applicable laws,
          rules and regulations in performance of its duties and obligations in
          connection with this Agreement.

DISTRIBUTION, MARKETING AND CLIENT SUPPORT ARRANGEMENTS

     ESI Determination of Marketing and Pricing.  ESI shall retain full
          discretion with respect to all decisions relating to distribution and
          marketing of FlexiFinancials and ESiFinancials, including, without
          limitation, the determination to introduce or withdraw ESiFinancials
          or FlexiFinancials, and the terms, conditions, and pricing of
          ESiFinancials and FlexiFinancials. ESI shall use commercially
          reasonable efforts to promote ESiFinancials and FlexiFinancials. Under
          no circumstances shall ESI misrepresent or mislead the features and
          functionality of FlexiFinancials or ESiFinancials, or make any claims
          detrimental to FLEXI.

     ESI shall bear all costs of preparation and writing of FLEXIEnhancements
          Documentation to the extent such enhancements shall not be
          incorporated within the generally available version of FlexiFinancials
          for sublicensing to FLEXI licensees, and delivery, duplication and
          production of ESiFinancials, FlexiFinancials, and FlexiFinancials
          Documentation and ESiFinancials Documentation delivered to End Users.

     ESI shall, at its own cost, provide sales, marketing, and support staff
          that are sufficiently trained in relation to ESiFinancials, and for
          such purpose ESI shall upon payment of the then-current professional
          service rates send to FLEXI suitably qualified employees of ESI for
          on-going training by FLEXI in matters relating to FlexiFinancials, its
          technical support and marketing.  The numbers of such employees, the
          times at which such employees are sent and the period for which such
          employees are sent to FLEXI shall be mutually agreed upon in writing.
          FLEXI agrees to provide the foregoing training at no additional cost
          to ESi up to twenty-five (25) man-days for ESi employees, provided
          such employees attend a regularly scheduled FLEXI training class for
          which FLEXI has available space for such employees.

     End User License.  Any distribution of ESiFinancials or ESiFinancials
          Documentation by ESI shall be pursuant to the terms and conditions of
          an End User License.

     Client Support.  ESI shall provide, at a minimum, a telephone "hotline" for
          technical support of ESiFinancials, FlexiFinancials, and Third Party
          Software, if any, for End Users, which includes, among other things,
          problem identification, verification, and resolution, to the extent
          possible.  Such hotline shall be available during regular business
          hours of ESI and shall be maintained by a trained staff on sufficient
          telephone lines to meet reasonably anticipated demand for service.
          ESI understands and agrees that FLEXI is not obligated to support ESI
          clients, except by providing support to ESI as provided in Section 0
          and assistance to ESi for Early Adopter License End User Licenses as
          agreed upon by the parties.  ESi further agrees not to deliver to any
          End User that is not subscribed to ESi's Maintenance or Enhancement
          Plan, or the like, any Maintenance Modifications or Enhancements to
          FlexiFinancials or ESiFinancials.

     Notwithstanding any of the foregoing, ESI shall not without the express
          written consent of FLEXI:

          give or make on behalf of FLEXI any other warranties, conditions,
                  guarantees or representations or to vary or modify in any way
                  such warranties, conditions, guarantees or representations as
                  given or made by FLEXI, provided that ESI may itself give or
                  make such warranties, conditions, guarantees or
                  representations that are more favorable to End-Users upon the
                  clear understanding that any additional liability shall be
                  incurred solely by ESI and

                                       8
<PAGE>
 
                   not by FLEXI, and ESI shall indemnify and hold FLEXI harmless
                   from any such additional liability during and after the term
                   of this Agreement, and such favorable terms and conditions
                   shall terminate upon termination of this Agreement.

          reproduce, sublicense, market, distribute, sell, support or service
                   FlexiFinancials or ESiFinancials to any customer that is
                   outside the Health Care Industry; or

          obtain FlexiFinancials for sublicensing from any person other than the
                   FLEXI;

     Export Compliance.  Notwithstanding the laws of any other jurisdiction, to
                   the extent that ESiFinancials or FlexiFinancials constitutes
                   "technical data" or such other classification for purposes
                   of the Export Control Regulations of the United States, no
                   copy of such software may be exported or re-exported to any
                   country that is at the time of export included in the
                   Department of Commerce's list of countries to which
                   exportation is restricted or prohibited unless that
                   exportation is authorized specifically by a special license
                   issued to ESI at ESi's own cost pursuant to the Exportation
                   Administration Regulations of the Department of Commerce or
                   any other United States government agency controlling the

OWNERSHIP

     Nothing herein shall be construed to assign or transfer any intellectual
                   property rights in FlexiFinancials Code and FlexiFinancials
                   Documentation, in which FLEXI retains all right, title, and
                   interest subject only to the rights and license hereby
                   granted.

     Upon ESi's payment of the Payments specified in Section 9.1 and Section
                   9.2, if applicable, and provided ESi remains current with its
                   Royalties as provided in Section 9.3 0, ESI shall retain all
                   right, title, and interest in the Interface and
                   ESiModifications, except to the extent FlexiFinancials Code
                   or Documentation is included therein. Notwithstanding the
                   foregoing, ESI acknowledges and agrees that creation of any
                   unauthorized modifications or enhancements or any use of
                   ESiModifications or the Interface separate and apart from
                   ESiFinancials or FlexiFinancials constitutes copyright
                   infringement or other infringement of the proprietary rights
                   of FLEXI. ESI hereby grants to FLEXI an irrevocable,
                   worldwide and fully paid-up license in and to the Interface,
                   ESiModifications, and ESiFinancials for the sole purpose of
                   enabling FLEXI to support ESi and, to the extent necessary,
                   End-Users or ESi licensees. Upon FLEXI's request, the
                   Interface, ESiModifications, and ESiFinancials shall be
                   recorded on or embodied in such suitable medium as mutually
                   agreed upon by the parties, and shall be promptly delivered
                   to FLEXI.

     ESI acknowledges and agrees that FlexiFinancials and portions of
                   ESiFinancials and the Interface constitutes confidential and
                   proprietary information and contains trade secrets of FLEXI.
                   Even should ESI license, distribute, market, service and
                   support ESiFinancials and the Interface under ESi's own name,
                   ESI agrees to attribute copyright, trade secret, and
                   trademark ownership of FlexiFinancials, FlexiFinancials
                   Documentation, ESiFinancials, ESiFinancials Documentation,
                   and the Interface in a form acceptable to and approved by
                   FLEXI, which form shall include at a minimum the information
                   provided in Exhibit 7.3 and the following language:

                    Copyright (C) 1992-1996 FlexiInternational Software, Inc.
                    All Rights Reserved.

                   FLEXI also agrees that portions of ESiFinancials and the
                   Interface contain confidential and proprietary information,
                   and contains trade secrets of ESI, and agrees to treat such
                   information as it treats its confidential and proprietary
                   information and trade secrets of a similar nature.

     ESI agrees that it shall not:

                                       9
<PAGE>
 
          alter, remove, or tamper with any trademarks, copyrights or other
               means of identification used on or in relation to FlexiFinancials
               or FlexiFinancials Documentation, including, but not limited to
               ESi's incorporation of FlexiFinancials into ESiFinancials and the
               Interface and ESiFinancials Documentation;

          use any of the trademarks, trade secrets, copyrights, or other
               intellectual property rights in any way that might prejudice the
               distinction, validity or goodwill of FLEXI; and

          acquire any rights and goodwill in the trademarks, trade secrets,
               copyrights, and other intellectual property rights.

     ESI further agrees that it shall:

          reproduce all trademarks, copyrights, or other means of identification
               used on or in relation to FlexiFinancials, the ESiFinancials,
               Interface, and documentation thereto;

          use the trademarks in compliance with all relevant laws and
               regulations;

          provide samples of ESiFinancials and the Interface, and such other
               materials that ESi uses of such trademarks, and use such
               trademarks in compliance with this Agreement.

          Failure to comply with the provisions of Section 7.4 and this Section
          shall constitute a material breach of this Agreement entitling Owner
          to terminate this Agreement or suspend ESi's use of the Trademarks,
          effective immediately, until such time that ESI has cured such failure
          and confirms in writing that ESi shall thereafter comply with this
          Section.

     ESI agrees that it will not claim any ownership rights in or to
          FlexiFinancials and FlexiFinancials Documentation and, to the extent
          necessary, shall, at the request and sole expense of FLEXI, execute,
          acknowledge, deliver or file all further acts, deeds, transfers,
          conveyances, assignments or assurances that FLEXI shall reasonably
          require to release any rights that might appear to have been acquired
          by ESI in FlexiFinancials, FLEXIEnhancements.

     Enforcement of Copyright. ESi agrees to promptly notify FLEXI of any
          infringement of any copyrights or other intellectual property rights
          of FLEXI in connection with or in relation to FlexiFinancials,
          ESiFinancials, the Interface, FlexiFinancials Documentation, and
          ESiFinancials Documentation. ESI shall use commercially reasonable
          efforts to fully enforce FLEXI's rights against infringers of its
          copyrights or other intellectual property rights in FlexiFinancials,
          ESiFinancials, the Interface, FlexiFinancials Documentation, and
          ESiFinancials Documentation by End Users and shall provide FLEXI
          reasonable assistance at its own expense in FLEXI's enforcement of its
          copyrights and intellectual property rights. ESI shall have materially
          breached this Agreement if it fails to so enforce rights against
          infringers within thirty (30) days after appropriate notification, if
          such failure results in a material loss of value in FlexiFinancials,
          ESiFinancials, FlexiFinancials Documentation, and ESiFinancials
          Documentation.

     U.S. Government Rights. ESi shall not provide ESiFinancials,
          FlexiFinancials, or Third Party Software ("Software") or Documentation
          to any unit or agency of the United States Government or such other
          government unless specified in an agreement between ESi and End User.
          Should ESi provide Software or Documentation to a unit or agency of
          the United States Government or such other government, ESi shall
          include any necessary provision in its contract with such unit or
          agency to limit the rights of the United States Government or such
          other government (as the case may be) in such Software or
          Documentation to the terms and conditions set forth in the End User
          License between ESi and End User. Such provision in the case of the
          United States Government shall note

                                      10

<PAGE>
 
          that such Software or Documentation is "commercial computer software"
          or "commercial computer software documentation" and that the United
          States Government's rights with respect to such Software or
          Documentation are limited by the terms and conditions of the End User
          License, pursuant to FAR (S)12.212(a) and/or DFARS (S)227.7202-1(a),
          as applicable. ESI agrees to place a legend "Restricted Rights
          Legend", in addition to the applicable copyright notices, on the
          Documentation, and on the tape and diskette labels, or on such other
          medium, as may be required.

     Nothing in this Agreement shall be deemed to preclude or prevent FLEXI from
          using in any manner it sees fit any expertise or know-how, or
          information embedded in the code, system design and configuration
          gained in the performance of this Agreement.

                    terms and conditions of an agreement within fifteen (15)
                    days of FLEXI's notification of FLEXI's desire or intention
                    to seek, or enter into discussions or enter into such
                    similar agreement;

               a license agreement with a FLEXI End User that is either an
                    affiliate of a present or future client of FLEXI ("FLEXI
                    Client") or said license is made in connection with a
                    license or series of licenses of FlexiFinancials to said
                    client of FLEXI and the sole motive of FLEXI for entering

               Canada, and such other ancillary agreements in support of the
               license agreement, provided FLEXI shall obtain ESi's consent,

               Canadian operations represent more than twenty-five percent (25%)

     Competing Products.

          Provided the Licenses are in effect: ESI shall not promote any the
               financial accounting software programs of any software products
               that compete with FlexiFinancials, except ESi may promote the
               following two products which may be considered to be competitive
               with FlexiFinancials, ESiFinancials and Third Party Software to
               be marketed by ESi hereunder, (y) its own proprietary Btrieve
               File System based accounts payable software program, provided the
               features and functionality of the such software program shall be
               substantially similar to the current features and functionality
               of such program and as such programs are enhanced for its current
               intended use, but in no event shall such programs be client
               server enabled, and (z) its own proprietary client server windows
               based invoicing matching program (as such program is commonly
               known in the industry as of the Effective Date of this
               Agreement), and, in both instances (y) and (z), ESi's proprietary
               software shall not include any programs acquired through, but not
               limited to, the purchase of another entity's programs, or the
               sale of or merger with another entity; and

          Provided the Exclusive Licenses are in effect, FLEXI shall not enter
               into any agreement to allow promotion and marketing of
               FlexiFinanicals in the Health Care Industry to any entity other
               than ESI as named herein, except as provided in Section 8.2 of
               this Section.

          Notwithstanding any provisions in this Agreement, FLEXI agrees not to
               market or solicit FlexiFinancials to those entities enumerated in
               Exhibit 8.1.2.5, enter into an agreement similar to this
               Agreement with any entity identified in Exhibit 8.3.2, nor
               promote a materials management computer software program (as such
               program is commonly known in the industry as of the Effective
               Date of this Agreement) in the Health Care Industry.

     Except for the rights granted herein to ESI, no right or license is granted
          under this Agreement by implication or otherwise.

PAYMENTS AND ROYALTIES
In consideration for the Licenses granted under this Agreement, ESI agrees to
make the following payments to FLEXI.

     Payments. ESI shall pay FLEXI Five-Hundred-Thousand Dollars ($500,000) non-
          refundable cash payment, except as provided in Section 3.1.2. Such
          payment shall be in accordance with the schedule in Exhibit 0.

     Exclusivity Payment. Upon ESi's election to expand its license grant as

                                       14
<PAGE>
 
     Royalty Payments.  Upon execution of this Agreement, ESI shall make
          payments ("Royalty Payments") to FLEXI equal to the applicable
          percentage specified in Exhibit 9.3 ("Royalty Rate") multiplied by the
          License-Related Gross Revenues.  As used herein, the term License-
          Related Gross Revenues shall mean the cumulative amount of all ESI
          executed licenses for ESiFinancials and/or FlexiFinancials from the
          date hereof respecting any and all licenses of ESiFinancials and
          FlexiFinancials (exclusive of implementation, consulting, support,
          education, maintenance, enhancements, and Third Party Software).

     Royalty Payments shall be paid in accordance with the Schedule enumerated
          in Exhibit 9.4 and shall commence no later than the 15th day of each
          month immediately after the execution by each End User of the End User
          License, but in no event shall Royalty Payments for an End User
          License be paid to FLEXI later than six (6) months after execution of
          each End User License.  Such Royalty Payments shall be reduced by the
          cumulative Non-Refundable Quarterly Payments made pursuant to Section
          9.5.  ESi may withhold a portion of the Royalty Payment associated
          with an End User License if ESi demonstrates in good faith that
          FlexiFinancials contains a material Error substantially precluding
          the End User from substantially using FlexiFinancials or ESiFinancials
          and FLEXI reproduces such error and fails to correct such error as
          provided in Section 4.3.  Upon FLEXI's correction of the material
          Error, ESi shall promptly pay to FLEXI that portion of the Royalty
          Payment withheld.

     Non-Refundable Scheduled Quarterly Royalty Payments. To the extent the Non-
          Refundable Scheduled Quarterly Royalty Payments as provided in Exhibit
          9.5a (or as adjusted due to a buy down of the Royalty Rate as provided
          in Exhibit 9.5b), exceed the aggregate actual royalty payments paid to
          FLEXI for such quarter, ESi shall make a non-refundable payment to
          FLEXI of the difference ("Non-Refundable Quarterly Payment") on or
          before the tenth (10th) day of the month following the end of the
          quarter.  At the end of each quarter, to the extent the cumulative
          royalty payments paid to FLEXI exceed the corresponding cumulative
          Non-Refundable Scheduled Quarterly Royalty Payments as provided in
          Exhibit 9.5a or Exhibit 9.5b, the difference shall be credited toward
          the next quarter's Non-Refundable Scheduled Quarterly Royalty
          Payments, and each quarter thereafter until such credit is exhausted.
          Non-Refundable Scheduled Quarterly Royalty Payments shall cease upon
          ESi's payment to FLEXI of $2,000,000 as provided in Exhibit 9.5a or
          such other amount as reflected in the applicable tables in Exhibit
          9.5b.

     Minimum Royalty Payment per End User License.  ESI agrees that the minimum
          Royalty Payment in connection with an End User License shall not be
          less than Royalty Rate specified in Exhibit 9.3 of (i) the then-
          current ESI suggested retail price for ESiFinancials as specified in
          Exhibit 9.6a and modified by ESi from time-to-time multiplied by
          discounted rate specified in such exhibit ("Discounted Rate") or (ii)
          the actual license fee for the End User, whichever is greater.  In the
          case of the Third Party Software specified in Exhibit 1.7, ESI agrees
          to pay FLEXI the Royalty Payments enumerated in Exhibit 9.6b.

     ESI further agrees to act in good faith towards FLEXI with respect to the
          Royalty Payments and shall not intentionally take any action with
          respect to the pricing of ESiFinancials to End Users where a
          motivation of such action is to reduce the amount of the Royalty
          Payments owing by ESI to FLEXI hereunder, including, but not limited
          to, disproportionately discounting or decreasing the suggested retail
          prices of ESiFinancials vis-a-vis ESI license fees or suggested retail
          prices for other products and services or disproportionately
          increasing ESI suggested retail prices for other products and services
          of ESI vis-a-vis the ESiFinancials or FlexiFinancials.

     Minimum Royalty Payment. Upon Acceptance, the minimum annual Royalty
          Payments from ESI to FLEXI for ESiFinancials or FlexiFinancials shall
          be as provided in Exhibit 9.8 

                                       15
<PAGE>
 
          ("Minimum Royalty Payment"). Minimum Royalty Payments shall cease upon
          ESi's payment to FLEXI of the actual cumulative Royalty Payments as
          provided in such Exhibit 9.8.

     Minimum Exclusivity Royalty Payment.  Upon ESi's exclusivity Notification
          as provided in Section 8.1.2.6, the Minimum Royalty Payment in order
          to maintain the Exclusive Licenses for ESiFinancials shall be as
          provided in Exhibit 9.9 ("Minimum Exclusivity Royalty Payments").  In
          the event ESI fails to pay to FLEXI during the course of the
          applicable period the Minimum Exclusivity Royalty Payment, ESI may pay
          to FLEXI on the fifteenth (15th) day after each anniversary following
          Notification the difference between the Minimum Exclusivity Royalty
          Payments and the actual Royalty Payments and the Non-Refundable
          Quarterly Payment, if any, to maintain the Exclusive Licenses granted
          herein or, notwithstanding any other provision in this Agreement, such
          Exclusive Licenses shall become non-exclusive for the remaining Term
          of this Agreement or any renewals thereto.

     Support and Maintenance Fees and Enhancement Fees.

          Support and Maintenance Fees. ESI shall pay FLEXI an annual cumulative
               support fee and renewal support fees corresponding to each End
               User License equal to (i) 2-1/2% of the total cumulative License-
               Related Gross Revenue for such End User License ("Base Support
               and Maintenance Fee") or (ii) the Base Support and Maintenance
               Fee plus any pro rata increase in ESi's actual support and
               maintenance fee to such End User, whichever is greater ("Support
               and Maintenance Fee"). On the fifteenth (15th) day of each month
               following the sixtieth (60th) day after ESi and an End User sign
               an End User License ("Anniversary Date") and every month
               thereafter, ESi shall pay FLEXI the Support Fee pro-rated
               monthly. The maximum Support Fee for all End User Licenses in any
               given month shall be $5,000.

               ESi may withhold the Support and Maintenance Fee of an End User
                    if ESi demonstrates in good faith that FlexiFinancials
                    contains a material Error substantially precluding the End
                    User from substantially using FlexiFinancials or
                    ESiFinancials and FLEXI reproduces such error and fails to
                    correct such error as provided in Section 4.3. Upon FLEXI's
                    correction of the material Error, ESi shall promptly pay to
                    FLEXI that portion of the Support and Maintenance Fee
                    withheld.

          Enhancement Fees. ESI also agrees that on the fifteenth (15th) day of
               each month following the first and each subsequent Anniversary
               Date to pay FLEXI an Enhancement Fee equal to (i) 5% of the total
               License-Related Gross Revenue ("Base Enhancement Fee") or (ii)
               the Base Enhancement Fee plus any pro rata increase in ESi's
               actual enhancement fee to an End User, whichever is greater
               ("Enhancement Fee").

          Termination of Support and Maintenance Fees, and Enhancement Fees;
               Reinstatement Fees.  Should an End User terminate its
               participation in the ESi Maintenance Plan or cease to pay ESi
               ESi Support and Maintenance Fees, and ESi Enhancement Fees
               (except as provided in Section 9.10.1.1), ESi shall cease to
               provide such End User support, maintenance, and enhancements.  In
               such event, FLEXI is not obligated to provide support, 
               maintenance, and enhancements to ESi on behalf of such End User
               and ESi shall not be obligated to pay FLEXI Support and
               Maintenance Fees, and Enhancement Fees for such End User.  In the
               event such End User resumes participation in ESi's support and
               maintenance plan, and/or enhancement plan, ESi shall pay to FLEXI
               a reinstatement fee equal to the same pro rata reinstatement
               charge, if any, such End User pays to 

                                       16
<PAGE>
 
               ESi to resume participation in ESi's support and maintenance
               plan, and/or enhancement plan.

          Third Party Fees. ESi also agrees to pay FLEXI a Support and
               Maintenance Fee and an Enhancement Fee for Third Party Software
               as specified in Exhibit 9.10.3.

          ESI further agrees to act in good faith towards FLEXI with respect to
               the above fees and shall not intentionally take any action with
               respect to the pricing of such enhancements, maintenance and
               support to End Users where a motivation of such action is to
               reduce the amount of the payments owing by ESI to FLEXI
               hereunder, including, but not limited to, disproportionately
               discounting or decreasing the suggested retail prices of such
               enhancement, maintenance and support vis-a-vis ESI fees or
               suggested retail prices for other products and services or
               disproportionately increasing ESI suggested retail prices for
               other products' maintenance and support of ESI vis-a-vis the
               FlexiFinancials or ESiFinancials maintenance and support fees.

     Taxes. ESI agrees to pay to FLEXI or make direct payments of the amount of
               any sales, excise or similar taxes other than income, or
               franchise tax payable by FLEXI which applicable law requires
               FLEXI to (i) collect from ESI in connection with the Licenses and
               support and maintenance of such Licenses, and (ii) pay to the
               applicable taxing authority.

     No Royalties for Demonstration, Evaluation or Educational Use.  No
               royalties shall be payable to FLEXI for ESi's demonstration of
               ESiFinancials or FlexiFinancials by ESi or use in educational and
               training activities conducted by ESi for End Users or prospective
               End Users who ESi is engaged in soliciting or licensing
               ESiFinancials or FlexiFinancials. Under limited circumstances,
               but for no more than three (3) End Users prior to Acceptance
               without the consent of FLEXI and in the case of more than three
               (3) End Users prior to Acceptance with the consent of FLEXI,
               which consent shall not be unreasonably withheld, ESi may provide
               FlexiFinancials for "Evaluation Use" for an End User who has
               executed an Evaluation License Agreement. "Evaluation Use" in
               excess of three (3) months shall subject the license to a Royalty
               Payment equivalent to the amount that would be due and owing if
               the End User had licensed FlexiFinanicals.

     No Right of Off-set.  ESI shall not have the right to set-off any amounts
               claimed to be owed by FLEXI to ESI hereunder against any Payments
               or Royalty Payments provided in this Section unless, and only to
               the extent that, ESI obtains an enforceable judgment against
               FLEXI or unless ordered or allowed by a court of competent
               jurisdiction.

WARRANTIES OF FLEXI

     Ownership; Right to License.  FLEXI represents and warrants to ESI that
               FLEXI has the authority to grant all Licenses granted herein.

     FLEXI warrants that as of the day and year first written above that it is
          not aware of any pending or threatened legal action challenging
          FLEXI's authority to perform its obligations hereunder, nor is FLEXI
          aware of any claim that FlexiFinancials violates or infringes any
          copyright, patent, or other intellectual property rights of a third
          party.

     Diligence; Conformity to Specifications. FLEXI represents and warrants to
          ESI that FlexiFinancials delivered hereunder has been or shall be
          prepared by FLEXI with due diligence and skill, and during the term of
          this Agreement, FlexiFinancials and FlexiTools shall conform in all
          material respects to the applicable documentation.  FLEXI does not
          represent, warrant or undertake that FlexiFinancials, including any
          future versions of FlexiFinancials, nor FlexiTools, including any
          future versions of the FlexiTools, is free from errors, omissions or
          inconsistencies that may prevent it or certain features from operating
          as described in the FLEXIDocumentation or as intended and whether
          alone or in conjunction with certain hardware configurations,
          operating systems 

                                       17
<PAGE>
 
          or other software, or will perform in an acceptable manner on any
          given hardware under any given operating system (whether or not
          recommended as a sufficient configuration in the Documentation or on
          the packaging).

     Pre-Release Software.  To the extent ESI receives a pre-release
          FlexiFinancials module, ESI understands that such module is not at the
          level of performance and compatibility of the final, generally
          available release product offering and is designated as pre-release
          code ("Beta Release"). It is understood that a Beta Release is not
          intended for production use and, therefore, is provided without any
          warranty of any kind and is distributed on an "AS IS" basis.

     The extent of FLEXI's liability under this warranty, TO THE EXCLUSION OF
          ALL OTHER REMEDIES IN CONTRACT, TORT, OR OTHERWISE, shall be limited
          to the correction or replacement of any defective item(s) in the
          physical media on which FLEXI delivers FlexiFinancials, Additional
          FLEXIEnhancements, and FlexiFinancials Documentation and, in the case
          of FlexiFinancials, shall be limited to Error Correction Services
          which FLEXI determines to be necessary at FLEXI's own cost and expense
          ("Warranty Correction Services"), provided, in both instances, written
          notice of any defective item(s) or Error is given to FLEXI during the
          warranty period and reduced to a writing in sufficient detail for
          FLEXI to reproduce the defective item. FLEXI shall provide
          commercially reasonable Warranty Correction Services consistent with
          FLEXI's Maintenance Plan and Error Correction Services as provided in
          Section 4.2 and Section 4.3, respectively, during FLEXI's regular
          business hours, excluding holidays.

     This warranty is invalidated and shall not apply if:  (w) FlexiFinancials
          and FlexiTools shall not be used in accordance with FLEXI's
          instructions as evidenced in writing in the current user documentation
          and other materials provided by Flexi; (x) FlexiFinancials (except as
          authorized pursuant to Section 8.1.1.2) or FlexiTools is altered,
          modified, translated, or reverse engineered; (y) any of ESi's
          equipment shall malfunction; or (z) any other cause within the control
          of ESI shall result in a feature or function of FlexiFinancials, and
          FlexiTools becoming inoperative.

     THE FOREGOING WARRANTIES ARE IN LIEU OF ALL OTHER WARRANTIES, EXPRESS OR
          IMPLIED, ORAL OR WRITTEN, WITH RESPECT TO THE SOFTWARE, INCLUDING, BUT
          NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS
          FOR A PARTICULAR PURPOSE.

INDEMNIFICATION

     Infringement of Intellectual Property Rights.  FLEXI hereby agrees to
          indemnify and defend ESI and its respective directors, officers,
          employees, representatives and agents against all claims losses,
          liabilities, damages, costs or expenses that FlexiFinancials and
          FlexiTools infringes against any U.S. or Canadian copyright,
          servicemark, trademark, trade name, or allegations that FLEXI has
          misappropriated trade secrets of a third party (excluding ESi and
          subsidiaries), and FLEXI will pay all costs, damages, and reasonable
          attorney fees finally awarded by a court of competent jurisdiction
          arising from or in connection with any such claim, provided, however,
          that said indemnification shall not apply to: (i) the use of a
          superseded or altered version of FlexiFinancials and FlexiTools if
          such infringement would have been reasonably avoided by use of the
          latest release of FlexiFinancials and FlexiTools; (ii) any such
          claims, losses, liabilities, damages, costs or expenses to the extent
          caused by any changes, modifications, to FlexiFinancials and
          FlexiTools by ESi or End Users; or (iii) any actions of ESI in
          violation of this Agreement.

     FLEXI shall have no obligation to defend ESI, or to pay any such costs,
          damages, and attorney fees for any claim based upon the combination,
          operation, or use of FlexiFinancials or FlexiTools with any programs
          or data not supplied by FLEXI if such infringement would 

                                       18
<PAGE>
 
          have been avoided by the combination, operation, or use of
          FlexiFinancials without such particular programs or data.

     In the event that FlexiFinancials or FlexiTools, or part thereof, as
          furnished under this Agreement and used within the scope of the
          Licenses hereunder is held in such a suit or proceeding to infringe a
          third party's proprietary right, and the use of FlexiFinancials or
          FlexiTools, or part thereof, is enjoined, FLEXI may, at its sole
          option: (y) procure for ESI the right to continue to use the Licenses
          granted hereunder; or (z) replace or modify FlexiFinancials or
          FlexiTools with non-infringing software. If FLEXI determines in its
          own discretion that neither of the foregoing options is commercially
          practicable, and only in the event that use of FlexiFinancials or
          FlexiTools, or part thereof, is determined in an administrative
          proceeding or by a court to actually infringe upon a third party's
          proprietary rights, or that in connection with a settlement of such
          claim, FLEXI shall cease to distribute FlexiFinancials or FlexiTools,
          or part thereof, FLEXI may terminate the Licenses, or part thereof,
          for FlexiFinancials or FlexiTools. Notwithstanding any other provision
          in this Agreement, upon such termination, FLEXI's maximum liability
          shall be no more than the amortized amount of the Royalty Payment
          received by FLEXI corresponding to the terminated End User License(s),
          or part thereof, based upon straight line amortization over a period
          of five (5) years. Sections 11.1 and 11.2 and 11.3 states the entire
          liability of FLEXI with respect to infringements of any patents,
          copyrights, trade secrets or other proprietary rights by
          FlexiFinancials or FlexiTools, or any part thereof.

     ESI hereby agrees to indemnify, defend and hold harmless FLEXI and its
          respective directors, officers, employees, representatives and agents
          from and against any and all claims, losses, liabilities, damages,
          costs or expenses which FLEXI may at any time suffer, incur or be
          required to pay by reason of any claim, action, suit or proceeding
          that may be made or instituted against FLEXI and its respective
          directors, officers, employees, distributors, representatives or
          agents for damages or other relief based upon any breach of any
          obligation of ESi under this Agreement or actual or alleged violation
          or infringement of any, U.S. or Canadian trademark, servicemark, trade
          name, copyright or allegations that ESi has misappropriated trade
          secrets of a third party due to any changes, modifications, or
          FLEXIEnhancements (to the extent FLEXI adhered to ESi's written
          specifications or other written instructions, if any),
          ESiModifications to FlexiFinancials, the Interface, and/or
          ESiFinancials.

     Conditions to Indemnification. The foregoing indemnities are conditioned on
          (1) prompt written notice of any claim or proceeding subject to
          indemnity; (2) reasonable cooperation by the indemnified party in the
          defense and settlement of such claim at the expense of the
          indemnifying party; and (3) prior written approval by the indemnifying
          party of any settlement, which approval shall not be unreasonably
          withheld.

     To the extent indemnified party delays notifying the indemnifying party of
          any demand, suit, claim or judgment, or adversely affects indemnifying
          party's ability to defend, settle, compromise or appeal any demand,
          suit, claim or judgment, the indemnifying party's obligation to
          indemnify Licensee shall be reduced accordingly.

     Notwithstanding the foregoing, indemnified party may participate in the
          defense or appeal of any such demand, suit, claim, or judgment should
          the indemnified party choose to participate, at its own expense (such
          expense not being indemnified by indemnifying party) and with
          attorneys of its own choice, provided, however, indemnifying party
          shall have sole control and authority with respect to any such
          defense, compromise, settlement, appeal or similar action.

CONFIDENTIAL INFORMATION; NON-SOLICITATION

                                       19

     Confidential Information.  This Agreement incorporates by reference the
          Confidentiality and Non-Disclosure Agreement executed by and between
          Enterprise Systems, Inc. and FlexiInternational Software, Inc. dated
          as of July 21, 1995. All confidential information exchanged between
          the parties during the term of this Agreement shall be governed by
          such Confidentiality and Non-Disclosure Agreement. This paragraph
          shall survive termination of this Agreement.

     Confidentiality of Terms.  Neither FLEXI nor ESI shall, without written
          authorization from the other party, disclose to any third party the
          terms and conditions of this Agreement except as may be necessary to
          establish or assert rights hereunder or as required by law; provided,
          however, that either party may, on a confidential basis, disclose this
          Agreement to its accountants, attorneys, and financing organizations.

     Press Release.  FLEXI and ESI agree that within ten (10) days after
          execution of this Agreement, the parties shall have prepared a

          otherwise retain employees of the other during the term of this
          Agreement and for a period of one (1) year thereafter without the
          express written consent of the other party.

FREEDOM OF INDEPENDENT DEVELOPMENT

     Nothing in this Agreement shall be construed as prohibiting or restricting
          either party from independently developing or acquiring and marketing
          materials or programs that are competitive with each others product
          lines, except as otherwise expressly provided herein. Neither party
          has any expectation nor has received any assurances that the business
          relationship established by this Agreement will continue beyond the
          stated term of this Agreement, nor that either party has any
          expectation of any anticipated amount of profits by virtue of this
          Agreement.

     Nothing in this Agreement shall be construed to constitute or create a
          joint venture, partnership, or formal business organization of any
          kind and the rights and obligations of each party shall be only those
          expressly set forth herein. Neither party shall have authority to bind
          the other, and neither party assumes any liabilities of the other
          party.

TERM AND TERMINATION

     Basic Term and Renewals.  This Agreement shall be effective on the date
          first above written and shall remain in force until the fourth
          anniversary from the date of Acceptance (or as such term may be
          extended as specified herein), unless sooner terminated as provided
          below.

          This Agreement shall automatically renew without the Exclusive
               Licenses for an additional year and successive one year terms
               with no Minimum Royalty Payment as provided in Section 9.8,
               provided ESi is current with all its obligations to FLEXI, and
               ESi has not materially breached this Agreement.

          This Agreement shall automatically renew with the Exclusive Licenses
               for an additional year and successive one year terms, provided
               the Exclusive Licenses were in effect for the previous year, ESi
               is current with all its obligations to FLEXI, and ESi has not
               materially breached this Agreement and, provided further, ESi
               paid to FLEXI $2,000,000 in actual Royalty Payments for the
               previous year or at the end of the such year ESi paid the
               difference between $2,000,000 and the actual Royalty Payments for
               such year as provided in Section 9.9.

     Discretionary Termination.  ESI and FLEXI may agree in writing at any time
          to terminate this Agreement.

                                       20
<PAGE>
 
     Termination by ESI for FLEXI Material Breach.  ESI may at its own
          discretion terminate this Agreement in writing upon FLEXI's breach of
          any of its material obligations hereunder, which obligations are not
          cured within ninety (90) days after delivery thereof.

     Termination by Flexi for ESI PAYMENT DEFAULT.  If ESI fails to pay any sum
          due to FLEXI in full by the due date thereof and fails to cure any
          such payment default within thirty (30) days after receiving written
          notice of such default from FLEXI, FLEXI shall be entitled (without
          prejudice to any other right or remedy it may have) to treat the non-
          payment as a breach of this Agreement entitling FLEXI to terminate the
          Agreement.

     Termination by FLEXI for ESI Material Breach. FLEXI shall have the right to
          furnish notice of termination of this Agreement in the event of a
          material and continuing breach by ESI of its obligations hereunder.
          Written notice to such effect identifying the breach upon which notice
          of termination is based shall be furnished to ESI and shall become
          effective ninety (90) days after delivery thereof unless ESI shall
          have cured the breach during such 90-day period. Curing of such breach
          shall render the notice void.

     Termination for Cessation of Business.  Either FLEXI or ESI may terminate
          this Agreement if the other party ceases conducting business in the
          normal course, becomes insolvent, makes a general assignment for the
          benefit of creditors, suffers or permits the appointment of a receiver
          for its business or assets or avails itself of or becomes subject to
          any proceeding under the Federal Bankruptcy Code or any other statute
          of any state relating to insolvency or the protection of rights of
          creditors.

     Continuing Rights and Obligations.  In the event of the termination of this
          Agreement for any reason, the provisions of this Section, and those
          other Sections or provisions of this Agreement which by their nature
          are intended to extend beyond the term of this Agreement, shall remain
          in full force and effect. Provided ESI makes all payments pursuant to
          Section O and the Agreement was not terminated pursuant to Section O,
          ESI shall have a license to continue to reproduce, sublicense, market,
          distribute, support and service ESiFinancials in connection with ESi's
          obligations to fulfill certain reasonable number of orders received
          prior to the effective date of termination of this Agreement. ESI
          shall have a license to continue to support clients in connection with
          the fulfillment of ESi's obligations under orders received during the
          term of the Agreement, provided ESI pays FLEXI the Support Fees
          provided in Section 9.10.1. Except to the extent the Licenses remain
          in force as provided in the foregoing sentence and except as provided
          elsewhere in this Agreement, upon any termination of this Agreement,
          all Licenses shall terminate (except End User Licenses granted to End
          Users by ESi entered into prior to termination) and the parties shall
          promptly destroy or return all copies of Confidential Information
          received hereunder, but may retain one copy of such information,
          provided such copy is retained with corporate counsel for archival
          purposes in case of a subsequent dispute between the parties.

REMEDIES

     Except as provided in Section 15.8, in the event that FLEXI violates the
          provisions of Sections 11 or O hereof, there shall be no limit on
          FLEXI's liability for the amount of monetary damages owed to ESI.

     Except as provided in Section 15.8, with respect to all other violations of
          this Agreement by FLEXI not described in Section 15.1, should a court
          of competent jurisdiction award monetary damages, FLEXI's liability
          for such damages to ESI shall be limited to the amount of any Royalty
          Payments theretofore paid by ESI to FLEXI for the previous twelve
          months. ESI agrees to waive any further recovery of damages in excess
          of the limit established pursuant to this Agreement.

     In the event that ESI violates the provisions of Section O or such other
          sections that require ESi to make payments to FLEXI, in addition to
          all other remedies, FLEXI may

                                       21
<PAGE>
 
            Cancel or suspend all services and any further delivery of
                   FlexiFinancials and ESiFinancials, and any other
                   deliverables; and/or

            Charge ESI interest on the outstanding balance due from time to time
                   at the rate of one and one-half percent (1%) per month or the
                   maximum lawful amount, whichever is less, compounded with
                   interest on the last day of each calendar month.

     Except as provided in Section 15.8, in the event ESi violates the
            provisions of Sections 8.1.1 and 8.1.2 hereof, ESi's liability for
            such violation shall be limited to an amount equal to the License-
            Related Gross Revenues and Maintenance and Support Fees and such
            other fees received by ESi as a result of such violation, or an
            amount equal to the license fee revenues and maintenance and support
            fees or such other fees, e.g., Royalty Payments and Maintenance and
            Support Fees, whichever is greater, FLEXI would have received but
            for ESi's violation of such section(s), whichever is greater, and
            interest on the amounts from the date of each violation until paid
            at the rate of one and one-half percent (1%) per month or the
            maximum lawful amount, whichever is less, compounded with interest
            on the last day of each calendar month.

     Except as provided in Section 15.8, in the event ESi violates the
            provisions of Section 11 and Section 12 hereof, there shall be no
            limit on ESi's liability for the amount of monetary damages owed to
            FLEXI.

     Except as provided in Section 15.8, with respect to all other violations of
            this Agreement by ESI not described in Section O, 15.3, and 15.4
            there shall be no limit on ESi's liability for the amount of
            monetary damages owed to FLEXI and should such liability be the
            result of an infringement upon FLEXI's intellectual property rights
            subsequent to a sale of shares, sale of assets, merger,
            consolidation or similar transaction where control of ESI or its
            assets is transferred to a competitor of FLEXI by such competitor,
            such damages shall be multiplied by three. Nothing in this provision
            shall waive any right to obtain such damages for any other
            violations.

     In the event that any party hereto shall default in the performance of any
            of said party's obligations hereunder, in addition to any and all
            other rights or remedies which a non-defaulting party hereto may
            have against said defaulting party, said defaulting party shall be
            liable to the non-defaulting party for all court costs and
            reasonable attorneys' fees incurred by the non-defaulting party in
            connection with the enforcement of said non-defaulting party's
            rights and remedies against said defaulting party.

     Notwithstanding any of the foregoing, under no circumstances shall either
            party be liable to the other party for any loss of profits or any
            incidental, special, exemplary punitive, indirect, or consequential
            damages, even if advised of the possibility of such matters.

     The parties agree that neither party shall be required to post any bond or
            similar payment in any proceedings wherein an injunction or similar
            relief is being sought by a party to enforce any of its rights or
            remedies hereunder.

ARBITRATION

     All disputes and claims arising under or in connection with this Agreement
            (except for the right of either party to apply to a court of
            competent jurisdiction for a temporary restraining order, a
            preliminary injunction, or other equitable relief to preserve the
            status quo or prevent irreparable harm) shall be submitted to the
            American Arbitration Association under and in accordance with its
            then-prevailing commercial arbitration rules, to the extent such
            rules do not conflict with this Agreement. The Arbitration will be
            governed by the laws of the State of Connecticut and held in the
            county of the charging party; in the case of ESi, Cook County

          Connecticut. The award rendered, if any, by the arbitrator shall be
          final and binding upon the parties and any judgment may be entered in
          any court having jurisdiction.

GENERAL

     Entire Agreement.  The provisions herein constitute the entire agreement
          between the parties with respect to the subject matter hereof and
          supersede all prior agreements, oral or written, and all other
          communications relating to the subject matter hereof. No amendment or
          modification of any provision of this Agreement will be effective
          unless set forth in a document that purports to amend this Agreement
          and is executed by both parties.

     Waiver.  No waiver by either of the parties to this Agreement of any
          condition, term or provision hereof shall be valid unless set forth in
          an instrument in writing signed on behalf of such party, and no such
          waiver shall be deemed a waiver of any preceding or subsequent breach
          of the same of any other condition, term or provision of this
          Agreement.

     No Assignment. Neither party shall without the prior written consent of the
          other party assign or transfer this Agreement, except by merger,
          reorganization, consolidation or sale of all or substantially all of
          the party's assets; provided in the case of ESI:

          In the event of an official announcement that ESi shall engage in a
               "Transaction" with a business entity (or an affiliate of such
               business entity) that is primarily engaged in the Health Care
               Industry that elects to terminate this Agreement, or a competitor
               of FLEXI enumerated in Exhibit 18.3.1a, the Licenses shall
               immediately terminate upon closing and ESi or its successor or
               assign shall pay to FLEXI at the closing of the Transaction the
               amount specified in Exhibit

                                       23
<PAGE>
 
               18.3.1b. In the event ESi enters into any discussions involving
               the exchange of information with a direct competitor of FLEXI in
               contemplation of a Transaction or otherwise, ESi shall not
               disclose any FLEXI Confidential and Proprietary Information.

          In the event of an official announcement that ESi shall engage in a
               "Transaction" with a business entity (or an affiliate of such
               business entity) that is not a competitor of FLEXI and primarily
               engaged in the Health Care Industry, who elects to accept
               assignment of this Agreement within thirty (30) days after the
               announcement of the Transaction, the Licenses shall remain in
               effect without the prior written consent of FLEXI, provided upon
               prompt written notice and written assumption thereof by the
               assignee to FLEXI, assign this Agreement in its entirety,
               provided further, ESi is current with all its obligations under
               this Agreement and continues to remain obligated hereunder.
          provided in the case of FLEXI,

          In the event of an official announcement that FLEXI shall engage in a
               "Transaction" with a business entity (or an affiliate of such
               business entity) that is a competitor of ESi as specified in
               Exhibit 8.3, ESi may terminate this Agreement. In the event FLEXI
               enters into any discussions involving the exchange of information
               with a direct competitor of ESi in contemplation of a Transaction
               or otherwise, FLEXI shall not disclose any ESi Confidential and
               Proprietary Information.

          For purposes of this Section, "Transaction" shall mean ESi or FLEXI
               merges, reorganizes, consolidates, or sells all or substantially
               all of its respective assets, or engages in a similar transaction
               where control of ESi or FLEXI or its respective assets are
               assigned by virtue of such transaction.

          Assignment.  Notwithstanding the foregoing, FLEXI reserves the right
               to assign payment under this Agreement or grant a security
               interest in this Agreement or such payment right to any third
               party without requiring that such third party be liable for the
               obligations of FLEXI under this Agreement.

     Force Majeure. Neither party shall be held liable for failure to fulfill
          its obligations hereunder if such failure is due to a natural
          calamity, act of government, or other cause beyond the control of such
          party.

     Days.  Should the date on which any payment or other performance of either
          of the parties hereto is due fall on a date that is a Saturday, Sunday
          or legal holiday (recognized as such by the Federal Government) or
          such other holiday recognized by one of the parties (together,
          "Holiday"), then payment or performance shall not be due until the
          next day which is not a Saturday, Sunday or Holiday.

     Governing Law. The validity, construction, and performance of this
          Agreement shall be governed by the substantive law of the State of
          Connecticut.

     Consent to Jurisdiction.  ESI hereby consents to the jurisdiction of any
          Federal or state court located in the State of Connecticut in
          connection with any action or lawsuit instituted by FLEXI against ESI
          to enforce any provision of this Agreement. FLEXI hereby consents to
          the jurisdiction of any Federal or state court located in the State of
          Illinois in connection with any action or lawsuit instituted by ESI
          against FLEXI to enforce any provision of this Agreement.
          Notwithstanding the foregoing, neither ESI nor FLEXI shall be
          prohibited from instituting actions against the other in any other
          court having jurisdiction over the parties.

     Severability. If any provision of this Agreement is held by a court of
          competent jurisdiction to be contrary to law, the remaining provisions
          of the Agreement will remain in full force and effect.

                                      24
