                               PROSPECTUS SUMMARY
 
  The following summary is qualified in its entirety by the more detailed
information and financial statements, including notes thereto, appearing
elsewhere in this Prospectus. This Prospectus contains certain statements of a
forward-looking nature relating to future events or the future financial
performance of the Company. Prospective investors are cautioned that such
statements are only predictions and that actual events or results may differ
materially. In evaluating such statements, prospective investors should
specifically consider the various factors identified in this Prospectus,
including the matters set forth under the caption "Risk Factors," which could
cause actual results to differ materially from those indicated in such forward-
looking statements. Except as otherwise indicated in this Prospectus or the
financial statements, all references to "NxTrend" and the "Company" refer to
NxTrend Technology, Inc. and its predecessors.
 
                                  THE COMPANY
 
  NxTrend is a leading provider of enterprise-wide software solutions that
address the critical business information requirements of durable goods
wholesale distributors. NxTrend offers wholesale distributors a single source
solution for information systems that are designed to enable the distributor to
increase profitability, enhance customer service and implement "best business
practices" in such critical areas as inventory management, order processing,
sales, customer service, warehouse logistics and strategic business analysis.
The Company seeks to serve as its customers' technology partner, helping them
respond to and anticipate the changing demands of the wholesale distribution
industry by designing, implementing and continuously improving their business
information systems. The Company's primary software products are open systems
based on the UNIX platform, and the Company's newest generation of products
utilize a Windows NT-based client/server architecture with Internet and
intranet capabilities. Over the course of its 17 year history of profitable
operations, the Company has established itself as the leading provider of
business information systems within its target market segments of the
distribution industry and as of February 28, 1997 had an installed base of over
1,000 customers.
 
  Durable goods wholesale distributors are operating in a rapidly changing and
intensely competitive environment. Industry consolidation has resulted in fewer
and more powerful distributors competing for market share while new entrants
are targeting increasingly specialized market segments. The proliferation of
"big box" retailers and wholesale clubs has also significantly altered the
competitive landscape, as such new competitors typically bypass traditional
distributors and instead purchase directly from manufacturers. While the
competitive environment has intensified, demand for increased value and
improved service from both manufacturers and customers has placed additional
pressures on wholesale distributors. Manufacturers are seeking increased levels
of marketing support from wholesale distributors, more efficient ordering
procedures and better information on distributors' inventory levels to monitor
"sell through." Concurrently, customers are attempting to better manage their
inventory levels and costs by demanding that their distributors provide prompt
information on product availability and rapid and reliable product delivery.
Both manufacturers and customers are endeavoring to rationalize their selling
and purchasing efforts by concentrating their business with a smaller number of
distributors. As a result of these factors, many distributors have been forced
to lower their margins in order to remain competitive. The various pressures
facing wholesale distributors have created a growing need for enterprise-wide
software solutions that provide a broad range of accurate and current
information to wholesale distributors and enable them to respond more quickly
to the needs of their manufacturers and customers and to manage their
businesses more efficiently and profitably.
 
  The Company's primary software packages, Trend, WDS-II and SHIMS, are
designed to automate key business processes and to integrate information among
customers and manufacturers. These products offer numerous modules in the areas
of (i) inventory management, (ii) warehouse logistics, (iii) electronic
commerce, (iv) business analysis, (v) sales, distribution and customer service,
and (vi) finance and administration, which can be configured to meet customers'
specific needs. The Company's Strategic Exchange client/server family of
 
                                       4
<PAGE>
 
products, based on Windows NT, complements the Company's primary products by
allowing customers to access, organize and analyze the information collected by
such products and to integrate that information into Windows-based productivity
tools. The Company's recently introduced Distribution@Work family of products
adds Internet and intranet capabilities to NxTrend's other software products.
 
  The Company's objective is to maintain and enhance its position as a leading
supplier of enterprise-wide software solutions for the durable goods wholesale
distribution market. The Company seeks to achieve this objective by (i)
leveraging its industry specific focus and industry reputation to further
penetrate its primary target market segments within the durable goods wholesale
distribution industry; (ii) providing a total solution to customers'
information technology needs; (iii) extending its solutions into additional
market segments within the durable goods distribution industry; (iv) enhancing
its technology leadership position through ongoing product development; (v)
continuing to offer products and services which generate significant recurring
and ongoing revenue; and (vi) increasing its product offerings, customer base,
skilled personnel and market segments by pursuing strategic acquisitions.
 
  The Company was incorporated in Iowa in 1979, was reincorporated in Colorado
in 1991 and was reincorporated in Delaware in 1996. The Company's principal
executive offices are located at 5225 North Academy Boulevard, Colorado
Springs, Colorado 80918, and its telephone number is (719) 590-8940.

                                 RISK FACTORS
 
  An investment in the Common Stock being offered hereby involves a high
degree of risk. In addition to other information contained in this Prospectus,
prospective investors should carefully consider the following risk factors
before purchasing the 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.
 
UNCERTAINTY OF FUTURE OPERATING RESULTS; FLUCTUATIONS IN QUARTERLY RESULTS
 
  The Company's quarterly operating results have fluctuated in the past and
are expected to continue to fluctuate in the future. These fluctuations may be
caused by many factors, including, among others: the size and timing of
individual orders; competitive pricing pressures; lengthy sales cycles;
budgeting cycles of customers; delays of customer installations due to delays
in delivery of hardware components by the Company's vendors; customer order
deferrals in anticipation of new products; the mix of products and services
sold; the variation of consulting, maintenance and other services as a
percentage of total revenue; the timing of introduction or enhancement of
products by the Company or its competitors; market acceptance of new products;
technological changes in platforms supporting the Company's products; changes
in networking or communication technology; changes in the Company's operating
expenses; personnel changes; the ability of the Company to increase its sales
and support personnel; software "bugs" and other product quality problems; and
general industry and economic conditions.
 
  A significant portion of the Company's historical revenue has been derived
from initial license fees (and related hardware and service sales) to a
limited number of customers, and the Company currently anticipates that this
trend will continue. Accordingly, any significant cancellation or deferral of
customer orders could have a material adverse effect on the Company's
operating results in any particular quarter. Further, due in part to the time
required to implement the Company's products and the Company's revenue
recognition policy which generally requires that a product has been delivered
and installed, the Company has satisfied all significant performance
obligations and collection is probable before revenue from the sale can be
recognized, the Company may experience potentially significant delays in
recognizing revenue. The Company in the past has realized a substantial
portion of its revenue in the last month of a quarter. In addition, it is not
uncommon for software companies to experience strong fourth quarters followed
by weak first quarters, in some cases with quarter-to-quarter declines in
revenue or operating profit. Further, many of the Company's customers have
their most active business cycles in the third calendar quarter and,
therefore, often elect to defer installation of a new system during that
period of time. In addition, the timing of initial license fee revenue is
difficult to predict because of the length and variability of the Company's
sales cycle.
 
  The Company's operating expense levels are relatively fixed and are based in
part on expectations as to future revenues. Compensation constitutes a
substantial portion of the Company's operating expenses and to a large degree
is fixed. Additionally, in their first year of employment by the Company, new
consulting personnel typically spend between eight and twelve weeks in
training, during which period they do not typically generate revenue. To the
extent anticipated revenue fails to materialize following the hiring and
training of new personnel, the Company's operating results would be adversely
affected. Consequently, any decline in revenues in any period, including a
decline due to delays in revenue recognition, could cause significant
variations in operating results from quarter to quarter and could result in
operating losses. To the extent that the Company's expectations regarding
future revenue are not realized, the Company's business, results of operations
and financial condition would be materially and adversely affected.
 
  As a result of these and other factors, the Company believes that period-to-
period comparisons of its results of operations are not necessarily meaningful
and should not be relied upon as indications of future performance. It is
possible that the Company's future quarterly operating results from time to
time will not meet the
 
                                       7
<PAGE>
 
expectations of market analysts or investors, which would likely have an
adverse effect on the market price of the Company's Common Stock. In addition,
there can be no assurance that the Company will achieve or sustain
profitability on a quarterly or annual basis. See "--Lengthy Sales Cycle" and
"Management's Discussion and Analysis of Financial Condition and Results of
Operations."
 
LENGTHY SALES CYCLE
 
  The sales cycle associated with the purchase of the Company's products
typically ranges from five to seven months and is subject to a number of risks
over which the Company has little or no control. For example, licensing of the
Company's products by its customers may involve a significant technical
evaluation and commitment of capital and other resources, with the attendant
delays associated with the approval of large capital expenditures and the
testing, implementation and acceptance of new technologies that affect key
operations. This evaluation process subjects the sales cycle associated with
the licensing of the Company's products to a number of significant risks,
including customers' budgetary and capital spending constraints and the
internal purchase approval processes of the customer, each of which may cause
a lengthy sales process lasting over several months. The length of the
Company's sales cycle may also vary substantially from customer to customer,
particularly for customers within different market segments. Because of such
possible lengthy sales cycles and the size of typical initial license fees
(and associated hardware and service sales), if revenue forecasted by the
Company from a specific customer for a particular quarter is not realized in
that quarter, the Company's operating results for that quarter could be
materially and adversely affected. See "--Uncertainty of Future Operating
Results; Fluctuations in Quarterly Results" and "Business--Sales and
Marketing."
 
ABILITY TO ATTRACT AND RETAIN SALES, SERVICE AND IMPLEMENTATION PERSONNEL
 
  The Company's future success is heavily dependent upon its ability to
attract, retain and motivate skilled technical and managerial personnel,
consulting personnel who assist in the implementation of the Company's
solutions, and sales personnel who are knowledgeable about enterprise-wide
software solutions and the wholesale distribution industry. The Company will
not be able to continue to increase its business at historical rates without
adding significant numbers of trained consulting personnel. Competition for
these types of personnel, in particular for technical, sales and
implementation personnel, is intense, and the Company competes in the market
for such personnel against numerous companies, including larger, more
established companies with significantly greater financial resources than the
Company. The software industry is characterized by a high level of employee
mobility and aggressive recruitment of skilled personnel. There can be no
assurance that the Company will be able to retain its current personnel, or
that it will be able to attract, assimilate or retain other highly qualified
technical, managerial, consulting or sales personnel in the future. The
inability to attract, hire or retain the necessary personnel could have a
material adverse effect upon the Company's business, operating results and
financial condition. See "--Dependence on Key Personnel" and "--Rapid
Technological Change and New Products."
 
DEPENDENCE ON KEY PERSONNEL
 
  The Company's continued success depends to a significant extent upon its
ability to retain certain key employees, including Guy M. Lammle, Chief
Executive Officer and President, Kathleen J. Cunningham, Chief Operating
Officer and Chief Financial Officer, and Ross J. Elliott, Executive Vice
President, Development. None of NxTrend's executive officers is bound by an
employment agreement, and Mr. Lammle is the only executive officer upon whom
the Company maintains "key-man" insurance. The loss of Mr. Lammle, Ms.
Cunningham, Mr. Elliott or certain other key employees or the Company's
inability to attract and retain other qualified employees could have a
material adverse effect on the Company's business and operations. See "--
Ability to Attract and Retain Sales, Service and Implementation Personnel,"
"--Rapid Technological Change and New Products," "Business--Employees" and
"Management--Executive Officers and Directors."
 
RAPID TECHNOLOGICAL CHANGE AND NEW PRODUCTS
 
  The market for the Company's software products is characterized by rapid
technological advances, evolving industry standards, changes in end-user
requirements and frequent new product introductions and enhancements.
 
                                       8
<PAGE>
 
The introduction of products embodying new technologies and the emergence of
new industry standards could render the Company's existing products and
products currently under development obsolete and unmarketable. Accordingly,
the Company's future success will depend upon its ability to enhance its
current products and develop and introduce new products that keep pace with
technological developments, satisfy varying end-user requirements and achieve
market acceptance. For example, the Company has modified certain modules of
its existing UNIX-based products and developed new products which can be
operated in an open client/server environment and on the Internet or an
intranet. Any failure by the Company to anticipate or respond adequately to
technological developments or end-user requirements, or any significant delays
in product development or introduction, could damage the Company's competitive
position and have a material adverse effect on revenues. There can be no
assurance that the Company will be successful in developing and marketing new
products or product enhancements on a timely basis or that the Company will
not experience significant delays in the future, which could have a material
adverse effect on the Company's business, results of operations and financial
condition. In addition, there can be no assurance that new products or product
enhancements developed by the Company will achieve market acceptance. The
Company may need to increase the size of its product development staff in the
near term to meet these challenges. There can be no assurance that the Company
will be successful in hiring and training adequate product development
personnel to meet its needs. See "--Ability to Attract and Retain Sales,
Service and Implementation Personnel," "--Dependence on Key Personnel" and
"Business--Product Development."
 
DEPENDENCE ON TREND
 
  The Company derives a majority of its revenue from the licensing of its
primary product, Trend, and associated service and hardware sales. The Company
anticipates that Trend will continue to account for a substantial portion of
revenue for the foreseeable future and that revenue from its SHIMS product
will continue to decrease as a percentage of total revenue. Accordingly, any
significant overall decline in revenue from Trend would have a material
adverse effect on the Company's business, operating results and financial
condition. The Company's future operating results are dependent upon continued
market acceptance of Trend and enhancements thereto. There can be no assurance
that Trend will continue to achieve market acceptance or that the Company will
be successful in marketing enhancements thereto. There can be no assurance
that current revenue or margin levels from this product will be sustained. The
Company anticipates that its existing and new competitors will introduce
additional products that compete with Trend, particularly if the demand for
wholesale distribution software products increases. In the event that the
Company's current or future competitors release new products that have more
advanced features, offer better performance or are more price competitive than
Trend, the Company's business, operating results and financial condition would
be materially and adversely affected. See "Business--Products" and "--Product
Development."
 
COMPETITION
 
  Competition in the enterprise-wide software solutions market is, and is
expected to remain, intense. The Company competes on the basis of product
quality, reliability, performance, ease of use, quality of support and price.
The Company believes that its primary competitors are Daly & Walcott, Inc.,
J.D. Edwards, Inc., Mincron SBC Corporation, Prelude, Inc., Prophet 21, Inc.
and Trade Service System, Inc. Certain of the Company's existing competitors,
as well as a number of potential competitors, have more established and larger
marketing and sales organizations, significantly greater financial and
technical resources and a larger installed base of customers than the Company.
In addition, certain of these companies have greater name recognition, more
established positions in the market, and long standing relationships with
customers. There can be no assurance that such competitors will not offer or
develop products that are superior to the Company's products or that achieve
greater market acceptance. The Company also competes against internally
developed legacy solutions in which potential customers may have invested
significant sums and committed valuable management resources to develop. Such
potential customers may resist committing the time and resources necessary to
convert to a third party software product and may instead choose to develop
and enhance their own systems internally. As demand for distribution industry
technology solutions expands, additional companies, some with significantly
greater
 
                                       9
<PAGE>
 
resources than the Company, may enter the market or increase their market
share by acquiring or entering into alliances with competitors of the Company.
There can be no assurance that the Company will be able to compete
successfully against its competitors or that the competitive pressures faced
by the Company will not adversely affect its business, results of operations
or financial condition. See "Business--Competition."
 
MANAGEMENT OF GROWTH
 
  The growth in the size and complexity of the Company's business and
expansion of its product lines and its customer base have placed and are
expected to continue to place a strain on the Company's management and
operations. The Company anticipates that continued growth will require it to
recruit and hire many new employees, including sales, consulting and technical
personnel. The Company's ability to compete effectively and to manage future
growth, if any, also will depend on its ability to implement and improve
operational, financial and management information systems on a timely basis,
to expand, train, motivate and manage its work force, in particular its direct
sales force and consulting services organization, and to deal effectively with
third-party systems integrators and consultants. There can be no assurance
that the Company will be able to manage or continue to manage its recent or
any future growth, and any failure to do so would have a material adverse
effect on the Company's business, operating results and financial condition.
 
INTEGRATION OF POTENTIAL ACQUISITIONS AND JOINT VENTURES
 
  As part of the Company's strategy, the Company seeks to acquire or enter
into business combinations with companies whose products or technologies will
complement or extend the Company's current products, services or target market
segments. In this regard, the Company completed the acquisition of certain of
the assets of Ultimate Data Systems, Inc. in 1995, and the acquisitions in
early 1997 of substantially all of the assets of each of Systemetrix
Corporation and an affiliated entity, Saber Systems, Inc. and Goretek Data
Systems, Inc. The most recent acquisitions, as well as any future
acquisitions, may expose the Company to increased risks, including those
associated with the assimilation of new operations and personnel, the
diversion of financial and management resources from existing operations, and
the inability of management to integrate successfully acquired businesses,
personnel and technologies. Furthermore, there can be no assurance that the
Company will be able to generate sufficient revenue from such acquisitions to
offset associated acquisition costs, or that the Company will maintain uniform
standards, controls, procedures and policies, which may result in the
impairment of relationships with customers, employees, and new management
personnel. Certain acquisitions may also result in additional expense
associated with the amortization of acquired intangible assets or potential
dilution from additional stock issuances. The Company may also evaluate, on a
case-by-case basis, joint venture relationships with certain complementary
businesses. Any such joint venture investment would involve many of the same
risks posed by acquisitions, particularly those risks associated with the
diversion of resources, the inability to generate sufficient revenues, the
management of relationships with third parties, and potential additional
expenses, any of which could have a material adverse affect on the Company's
business, financial condition or operating results. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations--
Acquisitions."
 
DEPENDENCE ON THIRD PARTY SOFTWARE AND HARDWARE; RELIANCE UPON HARDWARE SALES
 
  Most of the Company's products incorporate and use software products and
computer hardware and equipment developed by other entities. The relational
database management systems ("RDBMS") currently used in the Company's products
are those which the Company believes are best suited for the particular
applications required by the wholesale distributors in the Company's targeted
markets. These RDBMS have been developed by Progress Software Corporation
("Progress") and VMark Software, Inc. ("VMark"), and the Company has entered
into agreements with each of Progress and VMark that permit NxTrend to resell
such companies' products in connection with the sale of NxTrend products. The
operating systems on which the Company's products can function (UNIX, SCO-
UNIX, UnixWare and Windows NT) have been developed or are owned by Santa Cruz
Operations ("SCO") and Microsoft Corporation ("Microsoft"). The computer
hardware and related equipment sold as part of the Company's total solutions
are manufactured by Hewlett-Packard Company
 
                                      10
<PAGE>
 
("Hewlett-Packard"), International Business Machines Corporation ("IBM"),
Unisys Corporation, Data General Corporation ("Data General") and others.
There can be no assurance that all of these software or hardware providers
will remain in business, that such entities will continue to support these
product lines, that their product lines will remain viable or that these
products will otherwise continue to be available to the Company on a timely
basis in sufficient quantities or at all. For example, in the fourth quarter
of 1996 unavailability of certain hardware products resulted in delays in the
installation of Trend and the deferral of the revenue from outstanding
customer orders. If any of these entities ceases to do business or abandons or
fails to enhance or continue to support a particular product line, the Company
may need to seek other suppliers. In particular, if the Company was unable,
for any reason, to continue to incorporate Progress software into its Trend
and WDS-II products and to resell Progress software in connection with the
Trend and WDS-II products, the Company's business, results of operations and
financial condition would be materially and adversely affected.
 
  Further, for the year ended December 31, 1996, the Company derived
approximately 23.8% of its revenue and 7.9% of its gross profit from hardware
sales. Due to intense competition in the computer hardware market, and the
resulting declines in hardware prices, the Company's hardware revenue, as a
percentage of total revenue, as well as gross profit attributable to hardware
sales as a percentage of total gross profit, have also declined. The Company
expects these trends to continue. In addition, there can be no assurance that
the Company's current suppliers will not significantly alter their pricing in
a manner which could have a material adverse effect on the Company's business,
results of operations and financial condition. See "Business--Third Party
Products."
 
UNCERTAINTY OF MARKET ACCEPTANCE OF NEW PRODUCTS
 
  The Company has made a substantial investment in developing products which
utilize open systems technologies, such as client/server architectures, to
enable its customers to operate the Company's products on a variety of
operating systems, multiple hardware platforms and to integrate the Company's
products with third-party specialty software applications and legacy systems.
For example, the Company has developed the Distribution@Work family of
products to enable distributors, customers and manufacturers to access and
transmit information in a distributor's Trend or SHIMS database via the
Internet or an intranet. However, since the wholesale distribution industry
has been slow to adopt sophisticated business information technology, there
can be no assurance that the Company's new products will achieve or maintain
market acceptance. Further, there can be no assurance that the Company's
products will achieve and sustain advantages over other competitive
technologies. If the Company's enterprise network solutions do not achieve and
maintain significant and sustained market acceptance, the Company's business,
results of operations and financial condition could be materially and
adversely affected.
 
ABILITY TO EXPAND INTO NEW MARKETS
 
  The Company's future operating results are dependent upon its ability to
penetrate new vertical wholesale distribution market segments, such as
electronics, medical equipment and automotive parts. In order to penetrate new
markets such as these, the Company must develop or acquire the industry-
specific knowledge which is necessary to enable it to customize its primary
software products to meet the needs of wholesale distributors in these
markets. In addition, since wholesale distributors prefer to purchase systems
from well-established suppliers, the Company will need to establish a
reputation in each new market as a reliable provider of enterprise-wide
software solutions. If the Company's products do not achieve and maintain
significant and sustained market acceptance, or if the customer's applications
which incorporate the Company's products do not achieve lasting market
acceptance, the Company's business, results of operations and financial
condition could be materially and adversely affected.
 
DEPENDENCE ON DURABLE GOODS WHOLESALE DISTRIBUTION INDUSTRY
 
  The Company's business depends substantially upon the capital expenditures
of durable goods wholesale distributors in its targeted market segments, which
in part depend upon the demand for such distributors' products. A recession or
other adverse events broadly impacting the wholesale distribution industry in
the United States or other markets served by the Company could affect such
demand, forcing distributors in the Company's
 
                                      11
<PAGE>
 
target markets to curtail or postpone capital expenditures on information
technology systems and business consulting services. Any such change in the
amount or timing of capital expenditures in its target markets could have a
material adverse effect on the Company's business, results of operations and
financial condition.
 
PRODUCT LIABILITY; RISK OF SOFTWARE ERRORS OR FAILURES
 
  The Company may be subject to significant risks of professional and other
liability with respect to both its standard software products and its
consulting and support services. No assurance can be given that the
limitations of liability set forth in the Company's license agreements or
other contracts would be enforceable or would otherwise protect the Company
from liability for damages to a customer resulting from a defect in one of the
Company's products or arising as a result of professional services rendered by
the Company. Such a claim, if successful and of sufficient magnitude, could
have a material adverse effect on the Company's business, results of operation
and financial condition. In addition, software programs as complex as those
offered by the Company may contain undetected errors or "bugs" when first
introduced or as new versions are released that, despite testing by the
Company, are discovered only after a product has been installed and used by
customers. There can be no assurance that errors will not be found in future
releases of the Company's software, or that any such errors will not impair
the market acceptance of these products and adversely affect operating
results. Problems encountered by customers installing and implementing new
releases or with the performance of the Company's products could have a
material adverse effect on the Company's business, results of operations and
financial condition.
 
INTELLECTUAL PROPERTY AND PROPRIETARY RIGHTS
 
  The Company relies on a combination of copyright, trademark and trade secret
laws, employee and third-party nondisclosure agreements and other methods for
protecting ownership of its proprietary software. There can be no assurance,
however, that, in spite of these precautions, an unauthorized third party will
not copy or reverse-engineer certain portions of the Company's products or
obtain and use information that the Company regards as proprietary. The
Company provides source code to all SHIMS end-users and, in certain
circumstances may provide the source code for its Trend and WDS-II software
products, under licenses to its customers to enable them to customize the
software to meet particular requirements. Although the Company's source code
license contains confidentiality and nondisclosure provisions, there can be no
assurance that such customers will take adequate precautions to protect the
Company's source code or other confidential information. While the Company's
license agreements prohibit customers from exporting the product, the laws of
some foreign countries do not protect the Company's proprietary rights to the
same extent as do the laws of the United States. There can be no assurance
that the mechanisms used by the Company to protect its software will be
adequate or that the Company's competitors will not independently develop
software products that are substantially equivalent to or superior to the
Company's software products.
 
  NxTrend licenses products to end-users under license agreements which are
generally in standard form, although each license is individually negotiated
and may contain variations. The standard form agreement allows the licensee to
use the products solely on its computer equipment for its internal purposes,
and the licensee is generally not permitted to sublicense or transfer the
products. The Company's standard form license agreement includes a
confidentiality clause protecting the products. However, there can be no
assurance that such customers will take adequate precautions to protect the
Company's confidential information.
 
  None of NxTrend's software is patented. The Company believes that it has all
necessary rights to market its products, although there can be no assurance
that third parties will not assert infringement claims in the future. The
Company expects that, as the number of software products in the wholesale
distribution industry increases and the functionality of these products
further overlaps, software products will increasingly be subject to such
claims. There can be no assurance that infringement or invalidity claims (or
claims for indemnification resulting from infringement claims) will not be
asserted against the Company or that any such assertions will not materially
adversely affect the Company's business, operating results and financial
condition. Any such claim,
 
                                      12
<PAGE>
 
with or without merit, could be time-consuming, result in costly litigation
and diversion of resources, cause product shipment delays or require the
Company to enter into royalty or licensing arrangements. Such royalty or
licensing arrangements, if required, may not be available on terms acceptable
to the Company or at all. In the event of a successful claim of product
infringement against the Company and the Company's failure or inability to
license the infringed or similar technology, the Company's business, operating
results and financial condition could be materially adversely affected.
 
ABSENCE OF PRIOR TRADING MARKET; POTENTIAL VOLATILITY OF STOCK PRICE; NO
DIVIDENDS
 
  Prior to this offering, there has been no public market for the Common
Stock. There can be no assurance that an active trading market will develop
or, if one develops, that it will be maintained. The initial public offering
price of the Common Stock will be established by negotiation between the
Company and the representatives of the Underwriters. See "Underwriting" for
factors to be considered in determining the initial public offering price. The
market price of the shares of Common Stock could be subject to significant
fluctuations in response to the Company's operating results and other factors,
including announcements by its competitors. In addition, the stock market in
recent years has experienced extreme price and volume fluctuations that often
have been unrelated or disproportionate to the operating performance of
companies. These fluctuations, as well as general economic and market
conditions, may adversely affect the market price of the Common Stock. The
Company has never paid any cash dividends and does not anticipate paying cash
dividends in the foreseeable future. See "Dividend Policy."
 
SHARES ELIGIBLE FOR FUTURE SALE; REGISTRATION RIGHTS
 
  The sale of a substantial number of shares of Common Stock in the public
market following this offering could adversely affect the market price of the
Common Stock. Upon completion of this offering, the Company will have
outstanding an aggregate of 13,370,331 shares of Common Stock assuming (i) no
exercise of the Underwriters' over-allotment option, (ii) no exercise of
outstanding options and (iii) the automatic conversion of all outstanding
shares of the Company's convertible preferred stock. Of these shares, the
4,300,000 shares of Common Stock sold in this offering will be freely tradable
without restriction or further registration under the Securities Act, unless
such shares are held by "affiliates" of the Company, as that term is defined
under the Securities Act and the Regulations promulgated thereunder.
 
  The remaining 9,070,331 shares of Common Stock are "Restricted Shares" and
are subject to restrictions under the Securities Act. All of the Restricted
Shares are subject to lock-up agreements under which the holders have agreed
not to sell or otherwise dispose of any of their shares for a period of 180
days after the date of this Prospectus except with the prior written consent
of Montgomery Securities. Beginning 180 days after the date of the Prospectus,
8,422,535 Restricted Shares will become available for sale in the public
market pursuant to Rule 144 or Rule 701 under the Securities Act. By January
1998, up to an additional 318,791 shares will become eligible for sale in the
public market pursuant to Rule 144 or Rule 701 under the Securities Act.
During the period from March 1998 through March 2004, certain holders of the
Restricted Shares of Common Stock, or their transferees, will be entitled to
certain rights with respect to the registration of such shares under the
Securities Act. Registration of such shares under the Securities Act would
result in such shares becoming freely tradable without restriction under the
Securities Act (except for shares purchased by affiliates) immediately upon

ANTI-TAKEOVER CONSIDERATIONS
 
  Upon completion of this offering, the Board of Directors will have authority
to issue up to 5,000,000 shares of Preferred Stock and to fix the price,
rights, preferences, privileges and restrictions, including voting rights, of
those shares without further vote or action by the stockholders. The rights of
the holders of Common Stock will
 
                                      13
<PAGE>
 
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 may have the effect of delaying, deferring or preventing a
change in control of the Company, may discourage bids for the Common Stock at
a premium over the market price of the Common Stock and may adversely affect
the market price of and the voting and other rights of the holders of the
Common Stock. The Company has no present plans to issue shares of Preferred
Stock. In addition, certain provisions of the Company's bylaws and Delaware
law applicable to the Company could have the effect of discouraging certain
attempts to acquire the Company which could deprive the Company's stockholders
of the opportunities to sell their shares of Common Stock at prices higher
than prevailing market prices. See "Description of Capital Stock."
 
CONTROL BY OFFICERS, DIRECTORS AND PRINCIPAL STOCKHOLDERS
 
  Following completion of this offering, directors, executive officers and
principal stockholders of the Company, and certain of their affiliates, will
beneficially own approximately 66% of the outstanding shares of Common Stock.
Accordingly, these persons, individually and as a group, will be able to
effectively control the Company and direct its affairs and business, including
any determination with respect to the acquisition or disposition of assets by
the Company, future issuances of Common Stock or other securities by the
Company, declaration of dividends in the Common Stock and the election of
directors. Such concentration of ownership may also have the effect of
delaying, deferring or preventing a change in control of the Company. See
"Principal Stockholders."

                               RECAPITALIZATION
 
  On March 14, 1996, the Company effected a recapitalization (the
"Recapitalization"), whereby, among other things, the Company: (i) sold 26,000
shares of Series A Convertible Participating Preferred Stock ("Series A
Preferred Stock") for an aggregate purchase price of $26.0 million; (ii)
obtained a $25.0 million five-year term loan and a $5.0 million revolving line
of credit, of which $1.0 million was drawn at that time; (iii) redeemed all of
the Common Stock owned by Guy M. Lammle, a co-founder of the Company, members
of his immediate family and trusts established for their benefit (the
"Lammles") for a cash payment of $17.5 million and the issuance of 6,500
shares of Series B Convertible Participating Preferred Stock ("Series B
Preferred Stock") valued at $1,000 per share; (iv) redeemed all of the Common
Stock held by Roger H. Linn, a co-founder of the Company, members of his
immediate family and trusts established for their benefit (the "Linns") for a
cash payment of $31.5 million; (v) paid $7.0 million (before withholding
taxes) to certain employees of the Company in connection with the termination
of the Company's Unit Incentive Plan (the "Unit Incentive Plan"); and (vi)
sold 1,473,943 shares of restricted Common Stock to Guy M. Lammle at a
purchase price of $0.217 per share, subject to a repurchase right in favor of
the Company. See "Certain Transactions."
 
  Upon the closing of this offering, the outstanding Series A Preferred Stock
will automatically convert into 5,980,000 shares of Common Stock and 15,500
shares of Senior Redeemable Preferred Stock and the outstanding Series B
Preferred Stock will automatically convert into 1,495,000 shares of Common
Stock, 3,875 shares of Senior Redeemable Preferred Stock and 2,625 shares of
Junior Redeemable Preferred Stock. All shares of Senior Redeemable Preferred
Stock and Junior Redeemable Preferred Stock will be immediately redeemed upon
the consummation of this offering for total payments of approximately $19.4
million and $2.6 million, respectively. For the year ended December 31, 1996,
the Company incurred aggregate interest expense and amortization of debt
issuance costs of approximately $1.8 million relating to the term and
revolving debt incurred in connection with the Recapitalization. The Company
intends to use a portion of the net proceeds of this offering to repay the
term loan borrowing and any outstanding line of credit borrowing. See "Use of
Proceeds."
 
                                USE OF PROCEEDS
 
  The net proceeds to the Company from the sale of the 4,300,000 shares of
Common Stock offered by the Company hereby are estimated to be approximately
$51.4 million ($59.2 million if the Underwriters' over-allotment option is
exercised in full), assuming an initial public offering price of $13.00 per
share and after deducting the estimated underwriting discount and offering
expenses payable by the Company. The Company intends to use approximately
$19.0 million to repay the outstanding term loan whose interest rate is based
upon the prime rate of interest or LIBOR, at the Company's option, plus 25 to
275 basis points depending upon certain borrowing ratios. The weighted average
interest rate for the term loan as of December 31, 1996 was 7.78% and such
loan matures on December 31, 2000. The Company intends to use approximately
$500,000 to repay all outstanding balances under its line of credit which has
an interest rate of 8.50% as of February 28, 1997 and approximately $22.0
million to redeem 19,375 shares of Senior Redeemable Preferred Stock and 2,625
shares of Junior Redeemable Stock which will be issued upon the conversion of
the outstanding Series A Preferred Stock and Series B Preferred Stock. A
portion of the proceeds may also be used to acquire or invest in businesses,
products or technologies that complement or extend the Company's current
products, services or target market segments. While the Company from time to
time evaluates potential acquisitions of such businesses, products or
technologies, there are no present undertakings, commitments or agreements
with respect to any such acquisitions. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations--Acquisitions." The
balance of the proceeds will be used for working capital and general corporate
purposes.
 
  Pending such uses, the net proceeds of this offering will be invested in
short-term, interest-bearing securities.
 
                                DIVIDEND POLICY
 
  The Company currently intends to retain any future earnings to finance the
growth and development of its business and therefore does not anticipate
paying any cash dividends in the foreseeable future. In addition, the
Company's current loan agreement with its lenders contains a covenant
requiring the Company to obtain the lenders' consent before declaring
dividends. The payment of any future dividends will be at the discretion of
the Company's Board of Directors, will require consent of the Company's
lenders and will depend upon, among other things, the future earnings,
operations, capital requirements and financial condition of the Company. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations."

Stock being offered by the Company hereby, at an assumed initial public
offering price of $13.00 per share, and the application of the net proceeds
therefrom, including $22.0 million for the immediate redemption of all

                                   DILUTION
 
  The pro forma net tangible book value (deficit) of the Company at December
31, 1996, was approximately $(39,522,000) or $(4.42) per share. "Net tangible
book value" per share represents the amount of the Company's total tangible
assets less total liabilities, divided by the number of shares of Common Stock
outstanding (which includes, as outstanding, 7,475,000 shares issuable upon
conversion of all outstanding shares of preferred stock upon the completion of
this offering). After giving effect to the sale by the Company of 4,300,000
shares of Common Stock offered hereby (at an assumed initial public offering
price of $13.00 per share), and the application of the estimated net proceeds
therefrom, the pro forma net tangible book value of the Company at December
31, 1996 would have been approximately $11,528,000, or $0.87 per share. This
represents an immediate increase in such net tangible book value of $5.29 per
share to existing stockholders and an immediate dilution of $12.13 per share
to new investors. The following table illustrates this per share dilution:

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
OVERVIEW
 
  NxTrend is a leading provider of enterprise-wide software solutions that
address the critical business information requirements of durable goods
wholesale distributors. NxTrend offers wholesale distributors a single source
solution for information systems that are designed to enable the distributor
to increase profitability, enhance customer service and implement "best
business practices" in such critical areas as inventory management, order
processing, sales, customer service, warehouse logistics and strategic
business analysis.
 
  In 1990, the Company introduced Trend, its principal enterprise-wide
software solution, and since that time has continued to make enhancements,
revisions and upgrades to Trend, which is currently in release 7.0. In 1995,
the Company acquired its second enterprise-wide software solution, SHIMS,
which is currently in release 17.7, as a result of the purchase of certain
assets of Ultimate Data Systems, Inc. ("UDS") through an affiliated entity. In
early 1997, the Company acquired its third enterprise-wide solution, WDS-II,
as a result of the acquisition of certain assets of Goretek Data Systems, Inc.
("Goretek").
 
  The Company's total revenue grew from $18.8 million in 1994 to $35.1 million
in 1995 and $39.6 million in 1996. The 87.1% increase from 1994 to 1995 was
primarily attributable to the acquisition of the SHIMS product line from UDS
in February 1995 and to the continued growth of Trend sales. The Company
experienced strong growth in Trend orders from 1995 to 1996, which was
partially reflected in the increase in revenue from 1995 to 1996. However,
delays in the availability of third party hardware in the fourth quarter of
1996 resulted in delays in installation of Trend software and deferral of the
revenue from such orders. The Company anticipates improved availability of
hardware in 1997 and has expanded its implementation staff to permit more
timely completion of outstanding orders.
 
  The Company generates revenue from initial software license fees, annual
license and support fees, services (including software and hardware
implementation, enhancements, modifications and education), and from hardware
sold in conjunction with the Company's software products. The Company
ordinarily recognizes initial software license revenue when the Company is in
receipt of an executed license agreement, the product has been delivered and
installed, all significant performance obligations have been satisfied and
collection is probable. However, if the terms of the software license
arrangement provide for customer acceptance that is based on non-standard
criteria, revenue is recognized when the customer accepts the product pursuant
to those criteria or when the Company has performed all of its significant
performance obligations. Annual license fees and support agreements are
recognized ratably over the term of the license or support period.
Implementation and education services relating to the Company's software
products are performed and billed under separate agreements, and related
revenue are recorded when the services are performed.
 
  The Company derives a majority of its revenue from the license of its
primary product, Trend, and associated service and hardware sales. The
Company's marketing efforts are focused primarily on increasing its Trend user
base. The Company anticipates that Trend will continue to account for a
substantial and growing portion of the Company's total revenue for the
foreseeable future and that revenue from SHIMS will continue to decrease as a
percentage of total revenue. The Company does not expect to make a significant
number of new sales of SHIMS, and over time some of the existing SHIMS
customers are expected to upgrade to Trend. Accordingly, any significant
overall decline in revenue from Trend would have a material adverse effect on
the Company's business, operating results and financial condition. See "Risk
Factors--Dependence on Trend."
 
  For the year ended December 31, 1996, the Company derived 23.8% of its
revenues and 7.9% of its gross profit from hardware sales. In recent years,
hardware prices have been declining and consequently the Company's hardware
revenue, as a percentage of total revenue, as well as gross profit
attributable to hardware sales as a percentage of total gross profit, have
also declined. The Company expects these trends to continue. The Company acts
as a value added reseller or distributor for several third party software
companies, including Progress,
 
                                      19
<PAGE>
 
VMark and Microsoft. In return, the Company earns a margin or a royalty on the
resale of such software to its customers. See "Business--Products."
 
  The Company's gross profit has fluctuated significantly in the past and may
in the future, based on the mix of services and products licensed or sold by
the Company. The Company's software licenses have a substantially higher gross
profit than its services and hardware revenue. Therefore, to the extent the
Company's total revenue for any particular period includes a higher proportion
of lower margin services or hardware, the Company's overall gross profit will
be lower.
 
  The Company's business has experienced and is expected to continue to
experience some degree of seasonality due in large part to its customers'
buying cycles. Revenues are generally lower during the summer months when the
Company's distribution customers have their busiest operating cycles and
typically elect to defer the installation of a new software system or the
modification of an existing system.
 
RECAPITALIZATION
 
  On March 14, 1996, the Company effected the Recapitalization, whereby, among
other things, the Company (i) sold 26,000 shares of Series A Preferred Stock
for an aggregate purchase price of $26.0 million; (ii) obtained a $25.0
million five-year term loan and a $5.0 million revolving line of credit, of
which $1.0 million was drawn at that time; (iii) redeemed all of the Common
Stock held by the Lammles for a cash payment of $17.5 million and the issuance
of 6,500 shares of Series B Preferred Stock valued at $1,000 per share; (iv)
redeemed all of the Common Stock held by the Linns for a cash payment of $31.5
million; (v) paid $7.0 million (before withholding taxes) to certain employees
of the Company in connection with the termination of the Company's Unit
Incentive Plan; and (vi) sold 1,473,943 shares of Common Stock to Guy M.
Lammle at a purchase price of $0.217 per share, subject to a repurchase right
in favor of the Company. See "Recapitalization," "Certain Transactions" and
Note 1 of Notes to Financial Statements.
 
  Upon the closing of this offering, the outstanding Series A Preferred Stock
will automatically convert into 5,980,000 shares of Common Stock and 15,500
shares of Senior Redeemable Preferred Stock and the outstanding Series B
Preferred Stock will automatically convert into 1,495,000 shares of Common
Stock, 3,875 shares of Senior Redeemable Preferred Stock and 2,625 shares of
Junior Redeemable Preferred Stock. All shares of Senior Redeemable Preferred
Stock and Junior Redeemable Preferred Stock will be immediately redeemed upon
the consummation of this offering for total payments of approximately $19.4
million and $2.6 million, respectively. For the year ended December 31, 1996,
the Company incurred aggregate interest expense and amortization of debt
issuance costs of approximately $1.8 million relating to the term and
revolving debt incurred in connection with the Recapitalization. The Company
intends to use a portion of the net proceeds of this offering to repay the
term loan borrowing and any outstanding line of credit borrowing. See "Use of
Proceeds."
 
ACQUISITIONS
 
  As part of its business strategy, the Company intends to broaden its product
and service offerings and target market segments, as well as increase its
customer base and skilled personnel, in part through strategic acquisitions.
Such acquisitions may include software products and technologies intended to
complement or extend current product offerings in the Company's target market
segments. The Company believes that there will be opportunities to acquire
smaller enterprise software companies because wholesale distribution companies
are increasingly requiring that their long-term, enterprise-wide information
technology solutions be supplied by established companies, such as NxTrend.
The Company completed one acquisition in 1995 and three acquisitions in early
1997.
 
  In 1995, the Company, through an affiliated entity, acquired the SHIMS
product line when it purchased certain of the assets of UDS for cash of
approximately $1.9 million and the assumption of certain liabilities (the "UDS
Acquisition"). In addition to the SHIMS product line, the Company acquired
from UDS a complementary customer base, an additional source of recurring
revenue and a number of skilled employees. The Company currently has an
installed base of approximately 400 SHIMS customers.
 
 
                                      20
<PAGE>
 
  Effective January 2, 1997, the Company purchased substantially all of the
assets of Systemetrix Corporation and an affiliated entity ("Systemetrix"),
the Company's primary independent reseller in Canada, for $250,000 in cash,
63,888 shares of Common Stock and the assumption of certain liabilities (the
"Systemetrix Acquisition"). The Systemetrix Acquisition provides the Company
with 36 skilled employees, direct access to the Canadian wholesale
distribution markets, 40 existing Trend customers and approximately 200 other
customers using general purpose and wholesale distribution software running on
the IBM AS/400 and other proprietary IBM platforms.
 
  Effective January 2, 1997, the Company also purchased substantially all of
the assets of Saber Systems, Inc. ("Saber"), a Minneapolis based reseller of
Trend, for $1.3 million in cash, 57,500 shares of Common Stock and the
assumption of certain liabilities (the "Saber Acquisition"). The Saber
Acquisition provides NxTrend direct access to 20 existing Trend customers,
approximately 80 other customers running general purpose and wholesale
distribution software, and 35 additional skilled personnel. Additionally,
effective February 1, 1997, the Company purchased substantially all of the
assets of Goretek for $1.0 million in cash and the assumption of certain
liabilities (the "Goretek Acquisition"). Goretek is the Minneapolis-based
developer of WDS-II, a Progress-based wholesale distribution software product.
The Goretek Acquisition provides the Company with an additional wholesale
distribution software product, approximately 300 WDS-II customers and 26
skilled personnel (particularly in the area of Java-based development) and the
Company's initial point of entry into the electronics and medical equipment
market segments. Together, the Saber and Goretek Acquisitions also provide
NxTrend with a substantial direct presence in the Great Lakes/upper Midwest
region which was previously served only through Trend resellers.
 
  The UDS Acquisition was recorded as a purchase transaction for accounting
purposes which resulted in, and will result in, annual amortization expense
(which is included in general and administrative expense) of approximately
$520,000, $567,000, $567,000 and $45,000 in the years ending December 31,
1995, 1996, 1997 and 1998, respectively. See Note 3 of Notes to Financial
Statements. The Systemetrix, Saber and Goretek Acquisitions were recorded as
purchase transactions for accounting purposes and will result in aggregate
annual amortization expense of approximately $1,020,000, $1,052,000,
$1,052,000, and $33,000 in each of the years ending December 31, 1997, 1998,
1999 and 2000, respectively. If the Company completes future acquisitions
which are recorded as purchase transactions for accounting purposes,
additional amortization expenses may result.
 
  The Company may engage from time to time in discussions with respect to
potential acquisitions. The Company is not currently engaged in any
negotiations with respect to any potential acquisition and has no current or
pending contracts or commitments with respect to any acquisition. The
Company's recent acquisitions, as well as any future acquisitions, may expose
the Company to increased risks, including those associated with the
assimilation of new operations and personnel, the diversion of financial and
management resources from existing operations, and the inability of management
to integrate successfully acquired businesses, personnel and technologies. See
"Risk Factors--Integration of Potential Acquisitions and Joint Ventures."

COMPARISON OF YEARS ENDED DECEMBER 31, 1994, 1995 AND 1996
 
 
  Total Revenue
 
  Total revenue was $18.8 million, $35.1 million and $39.6 million in 1994,
1995 and 1996, respectively, representing increases of 87.1% from 1994 to 1995
and 12.8% from 1995 to 1996. The increase from 1994 to 1995 was due to the UDS
Acquisition in February 1995, which accounted for $8.3 million in revenue, and
a significant growth in Trend-related revenue. The increase from 1995 to 1996
was primarily due to growth in software license fees and annual license and
support fees due to the increase in the number of Trend customers. This
increase was offset in part by decreases in revenue attributable to hardware
sales caused by declining hardware prices and delays in availability of third
party hardware in the fourth quarter of 1996, which resulted in delays in the
installation of the Trend software and the deferral of revenue from such
orders.
 
    Software License Fees. Software license fee revenue was $6.4 million,
  $10.6 million and $12.4 million in 1994, 1995 and 1996, respectively,
  representing increases of 64.8% from 1994 to 1995 and 17.0% from 1995 to
  1996. The increase in 1995 was due to the recognition of several large
  Trend contracts, an overall increase in the average software license sale,
  and sales of additional modules and license seats to existing Trend
  customers. The increase in 1996 was primarily due to increases in the
  number of Trend customers, sales of additional modules and the number of
  seats for existing Trend customers.
 
                                      22
<PAGE>
 
    Annual License and Support Fees. Annual license and support fee revenue
  was $3.2 million, $8.7 million and $10.8 million in 1994, 1995 and 1996,
  respectively, representing increases of 171.1% from 1994 to 1995 and 23.6%
  from 1995 to 1996. The increase in 1995 was primarily due to the UDS
  Acquisition in February 1995 and its associated support revenue, which
  accounted for $3.9 million, and to a lesser extent, an increase in the
  installed base of Trend customers. The increase in 1996 was primarily due
  to the increase in the Trend customer base resulting in an increase in both
  annual license fee and support revenue.
 
    Services. Service revenue was $3.9 million, $6.2 million and $7.0 million
  in 1994, 1995 and 1996, respectively, representing increases of 59.4% from
  1994 to 1995 and 12.6% from 1995 to 1996. The increase in 1995 was due to
  an increase in the number of Trend customers resulting in an increase in
  service revenue, an increase in billing rates and the UDS Acquisition. The
  increase in 1996 was due to the increase in the Trend customer base
  resulting in an increase in demand for services.
 
    Hardware. Hardware revenue was $5.2 million, $9.6 million and $9.4
  million in 1994, 1995 and 1996, respectively, representing an increase of
  83.8% from 1994 to 1995 and a decrease of 1.5% from 1995 to 1996. The
  increase in 1995 was primarily due to the UDS Acquisition and an increase
  in the installed base of Trend customers resulting in an increase in add-on
  orders and upgrades from all customers. The decrease in 1996 was primarily
  due to a decrease in the average revenue from hardware sales for new
  contracts as a result of decreasing hardware prices. The Company believes
  that hardware prices will continue to decline.
 
  Total Cost of Revenue
 
  Total cost of revenue includes third party software product costs, costs of
maintenance and support, hardware product costs and the expenses (including
overhead) for personnel engaged in customer support and services. Total cost
of revenue was $9.9 million, $17.1 million and $18.2 million in 1994, 1995 and
1996, respectively, representing 52.7%, 48.8% and 45.9% of total revenue in
these periods. The dollar increase in 1995 cost of revenue was primarily due
to the UDS Acquisition. The dollar increase in 1996 was primarily due to costs
associated with the growth in annual license and support fees and services.
Decreases in cost of revenue as a percentage of total revenue in 1995 and 1996
were due to an increase in software license fees and annual license and
support fees as a percentage of total revenue, both of which have a
substantially lower cost of revenue than other products sold by the Company.
 
 
    Cost of Software License Fees. Cost of software license fees includes
  fees paid to third party software vendors. Cost of software license fees
  were $1.4 million, $1.9 million and $1.7 million in 1994, 1995 and 1996,
  respectively, representing 21.6%, 18.3% and 14.0% of software license
  revenue in these periods. The dollar increase in 1995 was primarily due to
  the increase in costs associated with the recognition of several large
  Trend contracts and an overall increase in the average software license
  sale. The dollar decrease in 1996 was primarily due to a decrease in the
  costs associated with the resale of certain third party software as well as
  an increase in add-on sales to existing customers. The cost of software
  license fees as a percentage of software license fees revenue decreased in
  1995 and 1996, primarily due to a decrease in third party software license
  fee revenue as a percentage of total software license fee revenue.
 
    Cost of Annual License and Support Fees. Cost of annual license and
  support fees consist of fees paid to third party software and hardware
  vendors and the expenses (including overhead) for personnel engaged in
  customer support. Cost of annual license and support fees were $1.3
  million, $3.4 million and $4.4 million in 1994, 1995 and 1996,
  respectively, representing 41.4%, 38.7% and 41.3% of annual licensing fees
  and support revenues in these periods. The dollar increase in 1995 was
  primarily attributable to the UDS Acquisition and the corresponding
  increase in support personnel.
 
    Cost of Services. Cost of services consists primarily of expenses
  (including overhead) for personnel engaged in implementation,
  modifications, enhancements and education services. Cost of services were
  $2.8 million, $3.9 million and $4.3 million in 1994, 1995 and 1996,
  respectively, representing 72.1%, 61.8% and 61.1% of service revenue in
  these periods. The dollar increase in 1995 was primarily attributable to
  the UDS Acquisition and the corresponding increase in service personnel.
  The decrease as a percentage of
 
                                      23
<PAGE>
 
  software services revenue in 1995 was due to an increase in billing rates
  and a change in the billing structure. The cost of services as a percentage
  of software services revenues decreased slightly in 1996, primarily because
  the Company increased the billing rate for its consultants.
 
    Cost of Hardware. Cost of hardware consists of fees paid to third party
  hardware vendors. Cost of hardware was $4.3 million, $8.0 million and $7.7
  million in 1994, 1995 and 1996, respectively, representing 83.5%, 83.2% and
  82.1% of hardware revenues in these periods. The dollar increase in 1995
  was primarily due to the UDS Acquisition, due to a large number of hardware
  upgrades purchased by the SHIMS customer base. Hardware revenue declined
  slightly in 1996 due to a decrease in hardware prices.
 
  Gross Profit
 
Gross profit was $8.9 million, $18.0 million and $21.4 million in 1994, 1995
and 1996, respectively. Gross margin increased from 47.3% in the year ended
1994 to 51.2% in the year ended 1995 and to 54.1% in 1996. These increases
were attributable primarily to the increases, as a percentage of total
revenue, in software license fees and annual license and support fees, both of
which have a substantially lower cost of revenue than other products sold by
the Company.
 
  Operating Expenses
 
    Research and Development. Research and development expenses are comprised
  primarily of the expenses (including overhead) for personnel engaged in the
  evaluation of new technologies and the design, development and testing of
  enhancements to existing software modules and products as well as new
  software modules and products. Research and development expenses were $1.3
  million, $2.6 million and $3.0 million in 1994, 1995 and 1996,
  respectively, representing 7.0%, 7.4% and 7.5%, respectively, of total
  revenue in these periods. The dollar and percentage increases in 1995 and
  1996 were primarily due to the addition of research and development
  personnel. The Company believes that it will continue to devote substantial
  resources to product development and that research and development expenses
  will continue to increase both in absolute dollars and as a percentage of
  total revenue.
 
    Sales and Marketing. Sales and marketing expenses are comprised primarily
  of salaries, commissions and promotional and advertising activities. Sales
  and marketing expenses were $1.9 million, $2.3 million and $2.8 million in
  1994, 1995 and 1996, respectively, representing 9.9%, 6.7% and 7.2%,
  respectively, of total revenue in these periods. The dollar increase in
  1995 was due to continued additions to sales and marketing personnel and
  related expenses, while the decrease as a percentage of revenue was due to
  the UDS Acquisition, whose sales and marketing expenditures, as a
  percentage of revenue, were considerably lower than those historically
  experienced by the Company. The increase in 1996 as a percentage of revenue
  was primarily due to an increase in sales and marketing personnel. The
  Company believes that sales and marketing expenses will continue to
  increase in absolute dollars and as a percentage of total revenue.
 
    General and Administrative Expenses. General and administrative expenses
  are comprised primarily of expenses (including overhead) for administrative
  personnel and goodwill expenses. General and administrative expenses were
  $2.9 million, $6.0 million and $6.0 million in 1994, 1995 and 1996,
  respectively, representing 15.6%, 17.1% and 15.1%, respectively, of total
  revenue in these periods. The increase in 1995 reflects the continued
  addition of personnel, as well as additional expenses stemming from the UDS
  Acquisition. The Company anticipates that general and administrative
  expenses will increase in absolute dollars as the Company expands its
  operations, adds additional personnel, amortizes goodwill from recent
  acquisitions and incurs additional expenses related to being a public
  company.
 
    Unit Incentive Plan. Effective January 1, 1995, the Company's
  stockholders approved the Unit Incentive Plan for the purpose of motivating
  and retaining key employees of the Company. Under the terms of the Unit
  Incentive Plan, the Company granted stock incentive units equal, in the
  aggregate, to 10% of the Company's outstanding Common Stock. Upon vesting,
  these units entitled the holders to cash payments equal to 100% of the fair
  market value of shares representing 10% of the Company's outstanding Common
 
                                      24
<PAGE>
 
  Stock. As a result of the Recapitalization in March 1996, the Company paid
  an aggregate of $7.0 million in cash to certain employees of the Company in
  exchange for their units and terminated the Unit Incentive Plan.
  Accordingly, the Company will not record any additional expenses in
  connection therewith. In accordance with the generally accepted accounting
  principles, the Company recorded compensation expense of $3.2 million in
  1995, the year in which the Unit Incentive Plan was originally adopted, and
  $3.8 million in 1996.
 
  Other Income (Expense), Net
 
  Other income (expense), net increased by 18.1% from $724,000 in 1994 to
$855,000 in 1995, and decreased to $(992,000) in 1996. The increase in 1995
was primarily due to the UDS Acquisition and associated commission income from
third party modification companies. The decrease in 1996 is primarily due to
the assumption by the Company of a term loan in connection with the
Recapitalization and the associated interest and fees due under the loan
agreement. See "--Liquidity and Capital Resources."
 
  Provision for Income Taxes
 
  The provisions for federal and state income taxes were $1.4 million, $1.7
million and $1.7 million for the years 1994, 1995 and 1996, respectively. The
effective tax rate was 39.2%, 36.4% and 35.2% for 1994, 1995 and 1996,
respectively.

  The Company's revenue has increased in each quarter in 1995 and 1996, with
the exception of the third quarter of 1996, which was affected by seasonal
factors. Notwithstanding the unusually strong third quarter in 1995 when the
Company recognized a large initial license of Trend, revenue is generally
lower during the summer months when wholesale distributors have their busiest
operating cycles. Software license fees were higher in the third and fourth
quarters of 1995 and for all of 1996 primarily due to an increase in upgrades
by existing Trend customers as well as additional sales of licenses. Services
revenue decreased in the second and third quarters of 1996 due to delays by
SHIMS customers in upgrading their systems until the new version of SHIMS code
had been released. Software license fees decreased in the fourth quarter of
1996 due to delays in installing new Trend systems attributable to delays in
hardware shipments from vendors.
 
  Gross margin ranged from 50.4% in the second quarter of 1995 to 57.3% in the
third quarter of 1996. Fluctuations in gross margin resulted from a varying
mix in a particular quarter by type of revenue, with higher margins from
software license revenue and lower margins from hardware revenue. Gross margin
in the fourth quarter of 1996 decreased to 50.7% due to an increase in
hardware upgrades to existing customers and a delay in the installation of
Trend software due to a delay in the availability of third party hardware.
 
  General and administrative expenses ranged from 12.6% of total revenue in
the fourth quarter of 1996 to 19.3% of total revenue in the second quarter of
1995. While general and administrative expenses have generally increased in
terms of absolute dollars, fluctuations in these expenses as a percentage of
total revenue are primarily due to varying levels of revenue, management
bonuses, and acquisitions and divestitures.

  The Company's quarterly operating results have fluctuated and are expected
to continue to fluctuate in the future. These fluctuations may be caused by
many factors, including, among others: the size and timing of individual
orders; competitive pricing pressures; lengthy sales cycles; budgeting cycles
of cutomers; delays of customer installations due to delays in delivery of
hardware components by the Company's vendors; customer order deferrals in
anticipation of new products; the mix of products and services sold; variation
of consulting, maintenance and other services as a percentage of total
revenue; timing of introduction or enhancement of products by the Company or
its competitors; market acceptance of new products; technological changes in
platforms supporting the Company's products; changes in networking or
communication technology; changes in the Company's operating expenses;
personnel changes; the ability of the Company to increase its sales and
support personnel software "bugs" and other product quality problems and
general industry and economic conditions.
 
  A significant portion of the Company's historical revenue has been derived
from relatively large initial license fees (and related hardware and service
sales) to a limited number of customers. Any significant cancellation or
deferral of customer orders, therefore, could have material adverse effect on
the Company's operating results in any particular quarter. The Company in the
past has realized a substantial portion of its revenue in the last month of a
quarter. It is not uncommon for software companies to experience strong fourth
quarters followed by weak first quarters, in some cases with quarter-to-
quarter declines in revenue or operating profit. Further, many of the
Company's customers have their most active business cycles in the third
calendar quarter and, therefore, often elect to defer installation of a new
system during that period of time.
 
  License revenue is also difficult to forecast because the market for the
Company's next generation products is uncertain and evolving. The Company's
expense levels are based, in part, on its expectations as to future revenues
and to a large extent are fixed. In particular, the Company is required to
increase consulting services capacity, including hiring additional consulting
personnel, in advance of anticipated license revenue. Therefore, the Company
may be unable to adjust spending in a timely manner, to compensate for any
unexpected revenue shortfall and, accordingly, any significant shortfall of
demand in relation to the Company's expectations or any material delay of
customer orders would have an almost immediate adverse effect on the Company's
operating results.
 
  As a result of the foregoing and other factors, the Company believes that
period-to-period comparisons of its results of operations are not necessarily
meaningful and should not be relied upon as indications of future performance.
Fluctuations in operating results may also result in volatility in the price
of the shares of the Company's Common Stock. See "Risk Factors--Uncertainty of
Future Operating Results; Fluctuations in Quarterly Results."
 
LIQUIDITY AND CAPITAL RESOURCES
 
  From inception through the beginning of March 1996, the Company financed its
operations primarily through cash generated from operations. On March 14, 1996
the Company effected the Recapitalization, which included a private placement
of preferred stock to certain investors and the establishment of new term and
revolving credit facilities. See "Recapitalization."
 
  In connection with the Recapitalization, the Company obtained a $25.0
million five year term loan and a $5.0 million revolving line of credit, of
which $1.0 million was drawn at that time. As of December 31, 1996 the balance
of the term loan was $19.0 million and $500,000 was outstanding under the line
of credit. The term loan and line of credit have interest rates, at the
Company's option, based on the prime rate or LIBOR plus between 25 and 275
basis points depending upon certain financial ratios. The weighted average
interest rate as of December 31, 1996 was 7.78% under the term loan. The
interest rate on amounts outstanding under the line of credit as of February
28, 1997 was 8.50%. The term loan and line of credit are collateralized by
substantially all of the assets of the Company, and require the Company to
maintain certain financial ratios. See Note 7 of Notes to Financial
Statements. The Company intends to use a portion of the proceeds of this
offering to repay the term loan and all outstanding balances under the line of
credit. See "Use of Proceeds."

  Net cash provided by operating activities for the years ending December 31,
1994, 1995 and 1996 were $2.8 million, $4.3 million and $1.8 million,
respectively. Net cash provided by operating activities in 1996, excluding the
$7.0 million nonrecurring expense paid under the Unit Incentive Plan, was $8.8
million.
 
  Cash provided by (used in) investing activities in 1994, 1995 and 1996 was
$92,000, $(2.6) million and $(2.0) million, respectively. Such investing
activities principally consisted in 1995 of the UDS Acquisition and in 1996 of
a $1.5 million noncompetition covenant payment made to Mr. Lammle in
connection with the Recapitalization and purchases of property and equipment.
See Note 3 of Notes to Financial Statements.
 
  Cash used in financing activities in 1994, 1995 and 1996 was $2.3 million,
$17,000 and $3.7 million, respectively. Such financing activities in 1994
consisted of repayment of borrowings to stockholders. In 1996, such financing
activities related to the Company's Recapitalization.
 
  Capital expenditures were approximately $108,000, $769,000 and $476,000 in
1994, 1995 and 1996, respectively. These expenditures were for property and
equipment, primarily computer hardware and furniture and fixtures. The Company
expects that capital expenditures in 1997 will not exceed the level of capital
expenditures in 1995. As of December 31, 1996 the Company had $730,000 in cash
and cash equivalents.
 
  The Company believes that the net proceeds from this offering, together with
its current cash balances, available lines of credit and funds generated from
operations, will be sufficient to meet its working capital and capital
expenditure requirements for at least the next 12 months. Thereafter, if the
Company's operating plans change, the Company may find it necessary to seek to
obtain additional sources of financing to support its capital needs, but there
can be no assurance that such financing will be available on commercially
reasonable terms, if at all.

GENERAL
 
  NxTrend is a leading provider of enterprise-wide software solutions that
address the critical business information requirements of durable goods
wholesale distributors. NxTrend offers wholesale distributors a single source
solution for information systems that are designed to enable the distributor
to increase profitability, enhance customer service and implement "best
business practices" in such critical areas as inventory management, order
processing, sales, customer service, warehouse logistics and strategic
business analysis. The Company seeks to serve as its customers' technology
partner, helping them respond to and anticipate the changing demands of the
wholesale distribution industry by designing, implementing and continuously
improving their business information systems. The Company's primary software
products are open systems based on the UNIX platform, and the Company's newest
generation of products utilize a Windows NT-based client/server architecture
with Internet and intranet capabilities. Over the course of its 17 year
history of profitable operations, the Company has established itself as the
leading provider of business information systems within its target market
segments of the distribution industry and as of February 28, 1997 had an
installed base of over 1,000 customers.
 
INDUSTRY BACKGROUND
 
  The durable goods wholesale distribution industry in the United States is
comprised of approximately 575,000 firms, which operate in a variety of market
segments and range from small, single location distributors having annual
revenues of less than $1.0 million dollars to large multi-location, multi-
national firms with annual revenue in excess of $1.0 billion dollars. The
Company's primary target market segments are wholesale distributors of
electrical supplies, plumbing, heating and air conditioning supplies, building
materials, and industrial supplies. There are approximately 60,000 firms in
these target market segments, with annual revenues ranging from under $5.0
million to more than $1.0 billion.
 
  Durable goods wholesale distributors are operating in a rapidly changing and
intensely competitive environment. Industry consolidation has resulted in
fewer and more powerful distributors competing for market share while new
entrants are targeting increasingly specialized market segments. The
proliferation of "big box" retailers and wholesale clubs has also
significantly altered the competitive landscape, as such new competitors
typically bypass traditional distributors and instead purchase directly from
manufacturers. While the competitive environment has intensified, demand for
increased value and improved service from both manufacturers and customers has
placed additional pressures on wholesale distributors. Manufacturers are
seeking increased levels of marketing support from wholesale distributors,
more efficient ordering procedures and better information on distributors'
inventory levels to monitor "sell through." Concurrently, customers are
attempting to better manage their inventory levels and costs by demanding that
their distributors provide prompt information on product availability and
rapid and reliable product delivery. Both manufacturers and customers are
endeavoring to rationalize their selling and purchasing efforts by
concentrating their business with a smaller number of distributors. As a
result of these factors, many distributors have been forced to lower their
margins in order to remain competitive. The various pressures facing wholesale
distributors have created a growing need for enterprise-wide software
solutions that provide a broad range of accurate and current information to
wholesale distributors and enable them to respond more quickly to the needs of
their manufacturers and customers and to manage their businesses more
efficiently and profitably.
 
  To compete effectively in this changing environment, wholesale distributors
must gather and process information on all phases of the product distribution
process, both to better understand their own businesses and to meet the
information and service requirements of the manufacturers and customers that
they serve. Historically, wholesale distributors have been slow to adopt new
business information technology, due primarily to cost concerns and limited
internal management information systems ("MIS") resources. Instead, they have
generally relied upon generic business software packages which are not fully
integrated throughout the business enterprise, do not provide the depth of
functionality and flexibility necessary to address the unique requirements
 
                                      29

of wholesale distributors and are not capable of electronically interfacing
with and capturing data from manufacturers and customers. The various
pressures facing wholesale distributors have created a growing need for
enterprise-wide software solutions that make available to wholesale
distributors a broad range of accurate and current information to enable them
to respond more quickly to the needs of their manufacturers and customers and
to manage their businesses more efficiently and profitably.
 
NXTREND SOLUTION
 
  NxTrend offers durable goods wholesale distributors single source,
enterprise-wide software solutions that are designed to enable the distributor
to increase profitability, enhance customer service and implement "best
business practices" in all of the critical areas of the distributor's
business. The Company provides a total solution to the business information
systems needs of wholesale distributors by integrating the Company's
application software with system hardware and third party specialty software,
and providing an array of services including implementation, customer support,
and specialized training. The Company believes that its total solution
concept, combined with its 17 years of industry experience, provides it with a
significant competitive advantage in addressing the unique and rapidly
changing business information system requirements of durable goods
wholesalers.
 
  The Company's primary software packages, Trend, WDS-II and SHIMS, are UNIX-
based and are designed to automate key business processes and to integrate
information among customers and manufacturers. These products offer numerous
modules in the areas of (i) inventory management, (ii) warehouse logistics,
(iii) electronic commerce, (iv) business analysis, (v) sales, distribution and
customer service, and (vi) finance and administration, which can be configured
to meet customers' specific needs. The Company's Strategic Exchange
client/server family of products, based on Microsoft Windows NT, complements
the Company's primary products by allowing customers to access, organize and
analyze the information collected by such products, and to integrate that
information into Windows-based productivity tools. The Company's recently
introduced Distribution@Work family of products add Internet and intranet
capabilities to NxTrend's other software products.
 
STRATEGY
 
  The Company's objective is to maintain and enhance its position as a leading
supplier of enterprise-wide software solutions for the durable goods wholesale
distribution market. To achieve this objective, the Company is pursuing the
following strategies:
 
  Further Penetrate Existing Vertical Market Segments. The Company intends to
continue to focus on providing enterprise-wide software solutions to its
primary target market segments: the electrical supply, plumbing, heating and
air conditioning, building materials, and industrial supply wholesale
distribution market segments. Although the Company believes that it has
established itself as the leading provider of business information systems to
these market segments, to date only a small portion of the firms operating in
these segments have adopted enterprise-wide systems. The Company believes that
it can increase its market share and generate additional sales from its
existing customer base by leveraging its total solution concept, industry
specific focus and long-standing industry reputation, enhancing current
products and introducing new modules and products designed to address the
specific needs of companies within its targeted market segments.
 
  Provide a Total Solution to Customers. The Company seeks to build long-term
customer relationships by providing a total solution for the information
technology needs of durable goods wholesale distributors based upon its fully-
developed modular suite of software products. Given the limited MIS resources
and unique requirements of durable goods wholesale distributors, the Company
serves as the customers' technology partner, assisting them in designing,
selecting and implementing all elements of their business information systems,
providing ongoing training and support and addressing evolving information
technology needs through sales of hardware and software upgrades.
 
  Pursue Additional Vertical Market Segments. NxTrend intends to expand into
additional vertical market segments within the durable goods wholesale
distribution industry by leveraging its proprietary technology, industry
knowledge and reputation. The Company believes that its products can be
readily adapted to address the information technology requirements of other
vertical market segments. The Company has identified the
 
                                      30
<PAGE>
 
electronics, medical equipment and automotive parts market segments as its
primary candidates for near-term expansion, based upon, among other things,
the size and competitive landscape of these market segments, as well as the
adaptability of the Company's products to such market segments. NxTrend's
recent Goretek Acquisition provides the Company's initial point of entry into
the electronics and medical equipment market segments.
 
  Enhance Technology Leadership Position. The Company seeks to enhance its
technology leadership position by increasing the functionality of existing
products, applying new technologies to extend the breadth of existing products
and developing new applications through innovative technologies. The Company
works closely with its customers to provide ongoing enhancements to their
existing applications. The Company's product development efforts also focus on
meeting evolving customer needs by incorporating into its products significant
advances in client/server architecture (including Internet and intranet
capabilities), advanced database systems and improved graphical user
interfaces. The Company's advanced research and development team evaluates new
technologies and applies them to develop innovative solutions that address
emerging needs and trends.
 
  Continue Emphasis on Recurring and Ongoing Revenue. The Company continues to
pursue a business model that emphasizes generating significant recurring and
ongoing revenue from its installed customer base. Recurring revenue from
annual license and support fees were $3.2 million, $8.7 million and $10.8
million in 1994, 1995 and 1996, respectively, representing approximately 17%,
25% and 27%, respectively, of the Company's total revenue in such years. In
addition, the Company receives a steady stream of revenue from the sale of
upgrades, add-on modules and customized modifications to its installed
customer base.
 
  Expand through Strategic Acquisitions. The Company intends to continue to
broaden its product and service offerings and target market segments, as well
as to increase its customer base and skilled personnel, in part through
strategic acquisitions. The Company completed the UDS Acquisition in 1995 and
the Systemetrix, Saber and Goretek Acquisitions in early 1997. Future
acquisitions may include software products and technologies intended to
complement or extend the Company's current products in its target market
segments. The Company believes that there will be opportunities to acquire
smaller enterprise software companies that serve the durable goods wholesale
distribution industry because distributors increasingly require that their
long-term, enterprise-wide information technology solutions be supplied by
established companies such as NxTrend.
 
PRODUCTS
 
  NxTrend offers durable goods wholesale distributors enterprise-wide software
solutions specifically designed to improve a distributor's financial
performance, enhance customer service and enable the implementation of "best
business practices" in such critical areas as inventory management, order
processing, sales, customer service, warehouse logistics and strategic
business analysis. The Company provides a total solution to the business
information systems needs of wholesale distributors by integrating the
Company's fully-developed modular suite of software products with third party
system hardware and specialty software, and providing an array of services
including implementation, customer support, and specialized training. The
Company offers five product families: three primary software products, Trend,
WDS-II and SHIMS, and two recently introduced complementary client/server
software products, Strategic Exchange and Distribution@Work. In addition, the
Company has developed a comprehensive suite of multimedia edutainment tools,
the Learning Centers, that enable users to learn how to effectively and
efficiently use the Company's products while also providing valuable wholesale
distribution industry knowledge through an engaging and easy-to-use format.
 
  Trend. The Company's principal product family, Trend, is a UNIX-based suite
of business software applications built around Progress' fourth generation
language ("4GL") and relational database. The Company's marketing efforts are
primarily focused on increasing its Trend user base among durable goods
wholesale distributors with annual revenues of $25 million and greater. Trend
is currently licensed to approximately 300 customers and, in 1996, the average
new Trend customer had annual revenues in excess of $50 million. Trend has a
modular design that allows a distributor to scale its investment by purchasing
the modules which satisfy its initial business information requirements and
adding new modules as its needs change.

  Initial Trend software license fees vary depending upon the performance
class of the hardware system, the initial selection of modules and the number
of users. The average initial software license fee for Trend in 1996 was
approximately $175,000, and generally ranges from $75,000 to $500,000, with
occasional license fees of up to $1.0 million. The initial Trend sale
(including software, hardware and services) in 1996 averaged approximately
$375,000. Customers also pay annual license fees equal to 10% of the initial
license fee in order to use the software after the warranty period and receive
Trend maintenance upgrades and new Trend releases. These annual license fees
are typically prepaid and may be increased each year. Virtually all Trend
customers also purchase the Company's annual support option which is mandatory
in the first year and is priced at 5% of the initial license fee and also may
be increased annually. In addition, many customers purchase the Company's
extended support services and operating environment support options.
 
  SHIMS. The Company's SHIMS product family is a UNIX-based suite of business
software applications which runs on an IBM platform and is built around
VMark's uniVerse relational database. The Company's marketing efforts with
respect to SHIMS are primarily focused on maintaining its SHIMS user base
among
 
                                      32
<PAGE>
 
durable goods wholesale distributors with annual revenues between $5 million
and $25 million in the plumbing, heating and air conditioning supplies and
electrical supplies market segments, and upgrading certain of those users to
Trend or WDS-II. SHIMS is currently licensed to approximately 400 customers.
SHIMS was acquired by NxTrend in early 1995 in connection with the UDS
Acquisition.
 
  SHIMS is designed to automate the day-to-day tasks of a distribution
business and offers numerous standard reports to support the areas of
purchasing, sales, inventory management and accounting. SHIMS is an integrated
suite of products which can be supplemented by several Value Added modules
developed by the Company which allows the distributor to scale its investment
by purchasing the modules that satisfy its initial needs and adding new
modules as its needs change.
 
  The following table describes the module groups incorporated into the SHIMS
product, as well as the Value Added modules which may be purchased separately.

</TABLE>
 
  Initial software license fees for SHIMS vary depending upon the initial
selection of Value Added modules and the number of users. The initial software
license fees average approximately $35,000, and generally range from $20,000
to $50,000. The average initial SHIMS sale (including software, hardware and
services) in 1996 was approximately $125,000. SHIMS users receive perpetual
licenses and, accordingly, do not pay annual license fees. However, the
Company only provides software maintenance, support and software upgrades for
SHIMS customers who pay quarterly support fees.
 
  WDS-II. In February 1997, NxTrend acquired the WDS-II product as part of the
Goretek Acquisition. Like Trend, the WDS-II product is a UNIX-based suite of
business software applications built around Progress' 4GL and relational
database. The Company's marketing efforts with respect to WDS-II will be
focused upon durable goods distributors with annual revenues between $2
million and $50 million. WDS-II is currently licensed to over 300 customers.
The current WDS-II customer base is concentrated in the electronics, medical
equipment and industrial supply segments of the durable goods distribution
industry. Because the WDS-II product is built around the same Progress
database as the Company's Trend product, NxTrend believes that the WDS-II
product will be compatible with the Company's Strategic Exchange and
Distribution@Work client/server products. The current suite of WDS-II modules
include Order Entry, Invoicing, Inventory Control, Purchasing, Inventory
Management, Accounts Receivable, Accounts Payable, General Ledger, Sales
Analysis, Contact Management,

Demand Forecasting, EDI and Warehouse Management. Like Trend, WDS-II has a
modular design which allows a distributor to purchase the modules that it
requires to meet its initial business needs and increase their functionality
by adding new modules as those needs change.
 
  Initial WDS-II license fees have historically ranged from $34,000 to
$500,000, depending upon the modules selected and the number of users. New
licenses of the WDS-II product will have an annual license and support fee
structure consistent with that used for the Trend, Strategic Exchange and
Distribution@Work products.
 
  Strategic Exchange. Strategic Exchange software modules allow distribution
executives to quickly analyze their company's business data from their Trend
or SHIMS database via user-friendly graphical user interfaces. The Company's
Strategic Exchange product family uses a client/server architecture based on
Microsoft Windows NT and integrates into a customer's existing host-based
computing environment. Strategic Exchange was initially released in May 1995
and approximately 95% of the Company's new licensees in 1996 purchased
Strategic Exchange products as part of the initial license.
 
  The Company's principal Strategic Exchange software module, Profit
Workbench, allows a distribution manager to rapidly monitor and analyze over
420 measures of business performance. Profit Workbench builds a strategic data
warehouse using Trend or SHIMS information and also provides sophisticated
query and analysis tools that allow the manager to identify business trends in
a graphical user environment. Profit Workbench includes components such as
First Glance and Financial Flowchart. First Glance graphically displays a
distributor's business performance as measured by eight key financial measures
selected by the user, such as sales, gross margin, accounts receivable and
inventory. Financial Flowchart permits the distribution executive to perform
financial analysis of his business using widely accepted financial formulas
and benchmarks. Other Strategic Exchange modules include (i) InVue, which
provides a graphical environment for Trend, WDS-II or SHIMS and allows
database information from these host-based systems to be downloaded into PC-
based applications such as spreadsheets and word processing programs, and (ii)
Parts Desk, which allows the user to navigate between Trend or SHIMS product-
related functions and CD-ROM product catalogs. InVue serves as a focal point
for all PC activity by allowing the user to access other programs such as
Trend, SHIMS, Strategic Exchange, Microsoft Office or an Internet browser. The
Company is currently in the process of integrating its recently acquired WDS-
II product with Strategic Exchange.
 
  Initial software license fees for Strategic Exchange modules are based upon
the module sold and number of users. The initial license fees range from $49
for a single user InVue license to $180,000 for a 100 user Profit Workbench
license. Customers are also charged annual license fees equal to 10% of the
initial license fee in order to use the software after the warranty period and
receive upgrades and new releases. These annual license fees, which are
typically prepaid and may be increased each year. Strategic Exchange customers
generally also purchase annual support, which is mandatory in the first year,
is priced at 5% of the initial license fee and also may be increased annually.
 
  Distribution@Work. NxTrend's Distribution@Work product family allows
wholesale distributors to incorporate the Internet into their daily business
activities. The Company has developed and intends to continue to focus upon
building Internet tools centered around information maintained in a
distributor's relational database. For example, the Company's Highway Hotel
product is a database driven management tool that enables a distributor to
easily establish, manage and automatically update its World Wide Web site.
Using the Company's proprietary interConnect middleware solution, the Company
has developed Trend@Work and SHIMS@Work, which permit wholesale distributors
to facilitate the flow of critical business information from their Trend or
SHIMS databases, such as pricing, product availability and order status, among
customers and manufacturers over the Internet and to engage in electronic
commerce. Highway Hotel was introduced in September 1996, and all other
Distribution@Work products are currently in beta release. License fees for
Distribution@Work will be server based and will vary depending upon the number
of database connections involved. The Company is currently in the process of
integrating its recently acquired WDS-II product with Distribution@Work.
 
 
                                      34
<PAGE>
 
  The initial software license fees are expected to range from $8,000 for a
single Highway Hotel license to approximately $100,000 for a 20 connection
interConnect license. These products will also have an annual license fee and
support fee structure similar to that used for Trend and Strategic Exchange.
 
PROFESSIONAL SERVICES
 
  As part of its total solution, the Company offers a variety of professional
services to its customers. The Company believes that its professional services
facilitate a distributor's successful adoption of NxTrend products, strengthen
the Company's relationships with its customers, enhance the Company's
industry-specific knowledge and elicit valuable customer feedback.
 
  Consulting. The Company's business consultants provide consulting, systems
analysis and technical services in order to assist distributors in planning,
designing, configuring and implementing new systems or in converting from
existing systems. These consultants typically have distribution industry
experience and training in both distribution operations and the Company's
products. The Company assists in the conversion of the customer's historical
databases to Trend, WDS-II or SHIMS and also assists distributors with the
initial installation of the new systems. The Company's business consultants
also conduct post-installation assessments in order to assure that the
customer's system is functioning properly, provide additional training and
education to increase the customer's use of the product and design and help
implement systems upgrades. As of February 28, 1997, there were 55 employees
within the Company's consulting group. The Company charges customers on an
hourly basis for the services provided by its consultants. Generally the
customer will prepay for a package of consulting hours for the planning,
design and the implementation of its system. In addition, the Company recently
started offering post-implementation consulting services to its customers on
an hourly basis.
 
  Software Integration. The Company's software integration group designs
custom modifications and enhancements to the Company's fully-developed modular
suite of software products to extend the capabilities of the Company's
products for the customer's specific environment. Most modifications and
enhancements are identified by the customer after the software and hardware
have been delivered to the customer and implementation services have been
completed, and typically do not result in significant changes to the Company's
primary products. Other custom modifications and enhancements are made on an
as-requested basis. Most Trend customers will request one to three such custom
modifications and enhancements per year, at a cost of approximately $2,000 per
custom modification or enhancement. SHIMS users generally use outside
consultants to make custom software modifications. The Company maintains a
library of frequently requested modifications which can be reused and quickly
adapted to address particular customer needs. As of February 28, 1997, the
Company's integration group consisted of 51 software integrators.
 
  Maintenance and Support. The Company offers its customers comprehensive
maintenance and support services. Under the Company's license agreements,
maintenance and support is mandatory for one year following the initial
license. Thereafter, virtually all Trend and SHIMS customers purchase
maintenance and support on a voluntary basis. The Company offers remote
accessibility to the customer's system in order to perform quick diagnostics
and provide on-line assistance, as well as telephone assistance. Support
services may be purchased either on an annual or on an hourly basis. A
customer can also purchase environmental support and seven days per week, 24
hours per day support on an hourly or pre-paid package basis. As of February
28, 1997, the Company's maintenance and support group consisted of 64
employees.
 
THIRD PARTY PRODUCTS
 
  As a part of its total solution concept, the Company has entered into
agreements with certain third party suppliers to resell hardware and software
in connection with the license of Trend, WDS-II and SHIMS.
 
  Third Party Hardware. The Company is a value added reseller of UNIX- and
Windows NT-based computer systems manufactured by IBM, Hewlett Packard, Unisys
and Data General that operate the NxTrend product families. Virtually every
customer that installs Trend, WDS-II or SHIMS purchases a computer system and
 
                                      35
<PAGE>
 
peripherals from the Company. As a value added reseller, the Company is able
to purchase the hardware at a discount for resale to its customers. See "Risk
Factors--Dependence on Third Party Software and Hardware; Reliance Upon
Hardware Sales."
 
  Third Party Specialty Software. The Company acts as a value added reseller
for several third party software companies, including Progress and VMark. The
Company integrates the Progress products into its Trend and WDS-II
implementations and the VMark products into its SHIMS implementation. In
return, the Company earns a margin on the resale of such software to its
customers. In order to receive ongoing maintenance and support, Trend and WDS-
II customers typically pay an annual license fee, which is shared by the
Company and Progress. The Company has entered into a value added reseller
agreement through January 1, 1999 with Progress for the resale of Progress
software to the Company's Trend and WDS-II customers. The Company has a value
added reseller agreement with VMark for the resale of VMark software to the
Company's SHIMS customers, which agreement has no specified termination date
but may be terminated by either party upon 90 days' prior written notice. See
"Risk Factors--Dependence on Third Party Software and Hardware; Reliance Upon
Hardware Sales."
 
CUSTOMERS
 
  As of February 28, 1997, the Company's products had been licensed to over
1,000 durable goods wholesale distributors within its targeted market
segments, of which approximately 300 are Trend users, approximately 300 are
WDS-II users and approximately 400 are SHIMS users. The Company's customers
range from small single-location distributors with annual sales of $2 million
to large, geographically dispersed within the United States multi-location
distributors with annual sales of over $1 billion. The Company markets Trend
to wholesale distributors with annual revenues of $25 million or more, WDS-II
to durable goods wholesale distributors with annual revenues of $2 million to
$50 million and SHIMS to wholesale distributors with annual revenues of $5
million to $25 million.
 
  The following table is a listing of the Company's ten largest customers in
each of its target market segments:

SALES AND MARKETING
 
  NxTrend markets and sells its products and services primarily through
regional sales representatives operating out of offices located in Atlanta;
Colorado Springs; Dallas; Green Bay; Houston; Minneapolis; St. Johns,
Newfoundland; Halifax, Nova Scotia; and Toronto, Ontario. This direct sales
force is segmented into regions and is responsible for developing new
customers and servicing existing accounts. The Company also has a network of
independent resellers located in Detroit, New York and Montreal, that sell,
implement, support and maintain NxTrend's products in their respective
territories. These resellers complement the Company's direct sales efforts,
broaden the customer base and strengthen the Company's market share by selling
to Trend and WDS-II customers with revenues under $25 million and/or in
ancillary markets or territories in which the Company does not have a direct
marketing effort.
 
  The sales cycle associated with new Trend, WDS-II and SHIMS sales is
generally five to seven months from the generation of the sales lead to the
execution of a license agreement. The sales process is typically focused on
the technical aspects of the Company's products and usually requires
participation from the Company's sales, product development, product
implementation and product support groups. The Company believes that the
participation of personnel from each of these areas is critical to the success
of the Company's sales efforts because it highlights the depth of the
Company's enterprise network systems expertise and demonstrates the breadth of
the total solution which the Company offers. See "Risk Factors--Lengthy Sales
Cycle."
 
  The Company's marketing activities are also focused on increasing industry
awareness of the Company's products, services and reputation for technological
leadership. Traditionally, the Company's marketing activities have included
issuing press releases, advertising in trade periodicals, attending trade
shows, and participating on technology committees within industry trade
associations. The Company also has active relationships with a number of
industry experts and leading universities which focus on the wholesale
distribution industry. In addition, the Company hosts an annual users
conference which, in 1996, attracted over 1,000 individuals from its customer
base. The users conference is both an opportunity to educate the Company's
user base and to introduce new products and services. As part of its strategy
of maximizing its customers' utilization of the Company's products, the
Company encourages certain of its SHIMS customers to consider Trend or WDS-II
solutions when appropriate to meet the specific business information needs of
such customers.
 
  As of February 28, 1997, the Company's sales and marketing organizations
consisted of 37 sales and 10 marketing personnel. The Company currently has
six resellers located in the United States and one reseller located in Canada.
 
PRODUCT DEVELOPMENT
 
  The Company seeks to strengthen its technology leadership position by
enhancing the functionality of existing products, applying new technologies to
extend the breadth of existing products and developing new applications
through innovative technologies. The Company seeks to design products with
enterprise-wide functionality applicable to most of its customers' needs. The
Company also develops multimedia, edutainment product interfaces to help
customers better use the Company's software products. The Company is currently
in the process of integrating its recently acquired WDS-II product with
Strategic Exchange and Distribution@Work.
 
  The Company continues to devote substantial development resources to
improving and enhancing the functionality of its Trend, WDS-II and SHIMS
solutions and to taking advantage of recent enhancements to the UNIX computing
platform and to the Progress and VMark databases. For example, the Company
recently added and will continue to add functionality which enables its
customers to better communicate, using electronic commerce and other methods,
with manufacturers and customers. The Company's product enhancement strategy
is developed based on feedback from its customers, various wholesale
distribution advisory councils and analysis of competitive products. Product
enhancements are delivered to customers through a combination of annual
releases and new modules. The Company's next product enhancement, Trend 8.0,
is scheduled to be released in the second half of 1997.
 
                                      37
<PAGE>
 
  The Company also focuses on meeting evolving customer needs by incorporating
into its products significant advances in client/server architecture
(including Internet and intranet capabilities), advanced database systems and
improved graphical user interfaces. The Company continues to enhance its
Strategic Exchange product family to make relevant business information
accessible to a broader range of its customers' employees. The Company also
continues to leverage the underlying Distribution@Work technology to enable
broader use of Internet and intranet capabilities by Trend and SHIMS
customers. These product extensions enable customers to take advantage of
their investment in and knowledge of Trend and SHIMS as well as the customer's
existing databases, while protecting this investment and information from
changes in underlying technology and front-end interfaces.
 
  In order to address emerging needs and trends within the wholesale
distribution industry, the Company maintains an advanced research and
development team that evaluates new technologies to be used in the development
of innovative solutions. Consisting of 12 individuals, this team has developed
products such as Profit Workbench, InVue, Parts Desk, Highway Hotel, Learning
Center, Manager's Handbook, Expert Advice, interConnect and interChannel. The
team is currently designing a new multi-layer architecture blending Java-based
user interfaces with reusable business objects and industry standard
databases, such as Microsoft SQL Server, Oracle, Progress and uniVerse. In
addition, the team is building products that enable more effective product
education and training through the use of Inter/intranet-based multimedia and
streaming video products.
 
  The computer software industry is subject to rapid technological change,
changing customer requirements, frequent new product introductions and
evolving industry standards that may render existing products and services
obsolete. As a result, the Company's position in its existing markets or other
markets that it may enter could be eroded rapidly by technology advancements
not embraced by the Company. The life cycles of the Company's products are
difficult to estimate. The products must keep pace with technological
developments, conform to evolving industry standards and address increasingly
sophisticated customer needs. There can be no assurance that the Company will
not experience difficulties that could delay or prevent the successful
development, introduction and marketing of new products or that new products
or product enhancements will meet the requirements of the marketplace and
achieve market acceptance. If the Company is unable to develop and introduce
products in a timely manner in response to changing market conditions or
customer requirements, the Company's business, operating results and financial
condition will be materially adversely affected. See "Risk Factors--Rapid
Technological Change and New Products."
 
  As of February 28, 1997, there were 65 employees in the Company's product
development organization. For the years ended December 31, 1994, 1995 and
1996, the Company's research and development expenses were $1.3 million, $2.6
million and $3.0 million, respectively.
 
COMPETITION
 
  Competition in the enterprise network software solutions market is, and is
expected to remain, intense. The Company competes on the basis of product
quality, reliability, performance, ease of use, quality of support and price.
The Company believes that its primary competitors are Daly & Wolcott, Inc.,
J.D. Edwards, Inc., Mincron SBC Corporation, Prelude, Inc., Prophet 21, Inc.
and Trade Service System, Inc. Certain of the Company's existing competitors,
as well as a number of potential competitors, have more established and larger
marketing and sales organizations, significantly greater financial and
technical resources and a larger installed base of customers than the Company.
In addition, certain of these companies have greater name recognition, more
established positions in the market, and long standing relationships with
customers. There can be no assurance that such competitors will not offer or
develop products that are superior to the Company's products or that achieve
greater market acceptance. The Company also competes against internally
developed legacy solutions in which potential customers may have invested
significant sums and committed valuable management resources to develop. Such
potential customers may resist committing the time and resources necessary to
convert to a third party software product and may instead choose to develop
and enhance their own systems internally. As demand for distribution industry
technology solutions expands, additional companies, some with significantly
greater
 
                                      38
<PAGE>
 
resources than the Company, may enter the market or increase their market
share by acquiring or entering into alliances with competitors of the Company.
There can be no assurance that the Company will be able to compete
successfully against its competitors or that the competitive pressures faced
by the Company will not adversely affect its business, results of operations
and financial condition.
 
INTELLECTUAL PROPERTY
 
  The Company relies on a combination of copyright, trademark and trade secret
laws, employee and third-party nondisclosure agreements and other industry
standard methods for protecting ownership of its proprietary software. There
can be no assurance, however, that, in spite of these precautions, an
unauthorized third party will not copy or reverse-engineer certain portions of
the Company's products or obtain and use information that the Company regards
as proprietary. The Company provides source code to all SHIMS end-users and,
in certain circumstances, may provide the source code for its Trend and WDS-II
software products under licenses to its customers to enable them to customize
the software to meet particular requirements. Although the Company's source
code license contains confidentiality and nondisclosure provisions, there can
be no assurance that such customers will take adequate precautions to protect
the Company's source code or other confidential information. While the
Company's license agreements prohibit customers from exporting the product,
the laws of some foreign countries do not protect the Company's proprietary
rights to the same extent as do the laws of the United States. There can be no
assurance that the mechanisms used by the Company to protect its software will
be adequate or that the Company's competitors will not independently develop
software products that are substantially equivalent or superior to the
Company's software products.
 
  NxTrend licenses products to end-users under license agreements which are
generally in standard form, although each license is individually negotiated
and may contain variations. The standard form agreement allows the licensee to
use the products solely on its computer equipment for its internal purposes,
and the licensee is generally not permitted to sublicense or transfer the
products. The Company's standard form license agreement includes a
confidentiality clause protecting the products. However, there can be no
assurance that such customers will take adequate precautions to protect the
Company's confidential information.
 
  None of NxTrend's software is patented. The Company believes that it has all
necessary rights to market its products, although there can be no assurance
that third parties will not assert infringement claims in the future. The
Company expects that, as the number of software products in the wholesale
distribution industry increases and the functionality of these products
further overlaps, software products will increasingly be subject to such
claims. There can be no assurance that infringement or invalidity claims (or
claims for indemnification resulting from infringement claims) will not be
asserted against the Company or that any such assertions will not materially
adversely affect the Company's business, operating results and financial
condition. Any such claim, with or without merit, could be time-consuming,
result in costly litigation and diversion or resources, cause product shipment
delays or require the Company to enter into royalty or licensing arrangements.
Such royalty or license arrangements, if required, may not be available on
terms acceptable to the Company or at all. In the event of a successful claim
of product infringement against the Company and failure or inability of the
Company to license the infringed or similar technology, the Company's
business, operating results and financial condition could be materially
adversely affected. See "Risk Factors--Intellectual Property and Proprietary
Rights."
 
EMPLOYEES
 
  As of February 28, 1997, NxTrend had 323 full-time employees, including 47
in sales and marketing, 65 in product development, 51 in software integration,
55 in consulting services, 41 in finance and administration and 64 in
maintenance and support services. None of the Company's employees is
represented by a collective bargaining agreement, nor has the Company
experienced any work stoppage. The Company considers that its relations with
its employees are good. The loss of certain key employees or the Company's
inability to attract and retain other qualified employees could have a
material adverse effect on the Company's business and operations. See "Risk
Factors--Ability to Attract and Retain Sales, Service and Implementation
Personnel."

PROPERTIES
 
  The Company's principal facility occupies approximately 45,000 square feet
in Colorado Springs, Colorado. The term of the lease extends through October
10, 1998; however, the Company has an option to extend the lease term by an
additional three or five years. The Company also leases office space in
Atlanta; Dallas; Green Bay; Houston; Minneapolis; St. Johns, Newfoundland;
Halifax, Nova Scotia; and Toronto, Ontario. The Company believes that its
facilities are adequate for its current needs and that suitable additional or
alternative space will be available in the future on commercially reasonable
terms as needed.
 
LEGAL PROCEEDINGS
 
  The Company is subject to various claims and business disputes in the
ordinary course of business. While the outcome of these matters cannot be
predicted with certainty, management anticipates that the ultimate outcome of
these issues will not have a material adverse effect on the Company's
financial condition or results of operations.

    remaining 50% of these options vest over a five-year period beginning on
    the fifth anniversary of the option grant date, subject to acceleration
    upon the Company's achievement of certain performance goals and upon
    redemption of the Company's redeemable preferred stock. Options to
    purchase 13,800 shares will vest for Ms. Cunningham and 10,350 shares for
    Mr. Elliott upon the Company's redemption of its redeemable preferred
    stock in connection with this offering.
 
1996 STOCK OPTION AND GRANT PLAN
 
  The Company's 1996 Stock Option and Grant Plan (as amended, the "Stock
Option Plan") was adopted by the Board of Directors on March 14, 1996 and
approved by the Company's stockholders on March 14, 1996. In January, 1997,
the Board of Directors and the Company's stockholders approved an amendment to
the Stock Option Plan. As of February 28, 1997, there were 4,203,169 shares of
Common Stock reserved for issuance under the Stock Option Plan.
 
  The Stock Option Plan provides for the grant of incentive stock options to
employees (including officers and employee-directors) and nonstatutory stock
options and restricted stock awards or issuances to employees, directors and
consultants. The Stock Option Plan is administered by the Compensation
Committee, which has the authority to select the persons to whom options,
stock grants and stock issuances (collectively, "Stock Awards") may be
awarded; to determine whether a Stock Award will be an incentive stock option
(within the meaning of Section 422 of the Internal Revenue Code of 1986, as
amended (the "Code")), a nonqualified stock option, a stock grant, a stock
issuance or a combination of the foregoing; to set the vesting schedules of
Stock Awards; to determine the number of shares subject to an option; and to
specify the type and amount of consideration to be paid to the Company upon
exercise of an option.
 
                                      46
<PAGE>
 
  Generally an incentive stock option granted under the Stock Option Plan must
have a term that expires no later than the tenth anniversary of the option's
grant date and must have an exercise price equal to at least 100% of the fair
market value of the Company's Common Stock on the date of option grant. With
respect to an incentive stock option granted to a person who beneficially owns
securities representing more than 10% of the voting power of all outstanding
capital stock of the Company (or a parent or subsidiary of the Company), the
exercise price of the option must equal at least 110% of the fair market value
of the Company's Common Stock on the option grant date and the term of the
option may not exceed five years. The aggregate fair market value, determined
at the time of grant, of shares of Common Stock with respect to which
incentive stock options are first exercisable by an optionee (under all plans
of the Company and a parent or subsidiary of the Company) in any calendar year
may not exceed $100,000. If an optionee's employment or service as a director
with the Company or a subsidiary of the Company terminates, the Compensation
Committee may in its discretion provide, at any time, that any outstanding
option granted to such optionee under the Stock Option Plan shall be
exercisable for three months following termination of employment or service as
a director, subject to the expiration date of such option. An option granted
under the Stock Option Plan is not transferable by the optionee except by will
or by the laws of descent and distribution and may be exercised during the
optionee's lifetime only by the optionee or by his or her guardian or legal
representative.
 
  Upon certain changes in control of the Company, the Stock Option Plan and
all outstanding awards under the Stock Option Plan shall be terminated unless
provision is made in connection with such transaction for the assumption of
options theretofore granted or the substitution for such options of new
options of the successor entity or parent thereof. The Stock Option Plan will
terminate in March 2006 unless sooner terminated by the Board of Directors.
 
  Under the Stock Option Plan, as of February 28, 1997, no shares of Common
Stock had been issued upon the exercise of options granted, options to
purchase 1,335,932 shares of Common Stock at a weighted average exercise price
of $2.43 were outstanding, restricted stock awards for 1,473,943 shares had
been granted and 1,393,294 shares remained available for grant. As
compensation for service on the Board of Directors, the Company grants options
to purchase 28,750 shares of Common Stock upon a director's initial election
to the Board of Directors.
 
EMPLOYEE STOCK PURCHASE PLAN
 
  [To be filed by amendment]
 
401(K) PLAN
 
  The Company originally established a Profit Sharing Plan on February 1, 1982
as a defined contribution plan under the provisions of Section 401(a) of the
Internal Revenue Code for the benefit of eligible employees. Under the terms
of such plan, the Company was allowed to contribute up to 15% of all eligible
compensation, as defined in the plan document, for all eligible employees.
During some years, such payments were made in the form of cash bonuses rather
than as contributions directly to such plan. The plan was restated on April
15, 1993 to include a tax qualified deferred plan as described in Section
401(k) of the Internal Revenue Code (the "401(k) Plan"). Pursuant to the
401(k) Plan, as amended to date, eligible employees may elect to reduce their
compensation by up to the lesser of 15% of their eligible compensation or the
statutorily prescribed limit ($9,500 in 1996) and have the amount of such
reduction contributed to the 401(k) Plan. The trustee of the 401(k) Plan, at
the direction of each participant, invests the assets of the 401(k) Plan in
designated investment options. The 401(k) Plan is intended to qualify under
Section 401 of the Internal Revenue Code so that contributions to the 401(k)
Plan, and income earned on the 401(k) contributions are not taxable until
withdrawn, and so that the contributions of the Company will be deductible
when made. Additional discretionary contributions may be made by the Company
to the 401(k) Plan. Such discretionary contributions to participants are
allocated based on the percentage of the participant's compensation to the
total compensation of all participants eligible to share in the contribution.
No such discretionary contributions were made by the Company during 1996.

LIMITATION OF LIABILITY AND INDEMNIFICATION MATTERS
 
  The Company's Amended and Restated Bylaws, to be adopted prior to the
closing of this offering, will provide that the Company shall indemnify its
directors and executive officers and may indemnify its other officers,
employees and other agents to the fullest extent not prohibited by Delaware
law. The Company is also empowered under its Amended and Restated Bylaws to
enter into indemnification contracts with its directors, officers, employees
or agents, and to purchase insurance on behalf of any person it is required or
permitted to indemnify. Pursuant to this provision, the Company has entered
into indemnity agreements with each of its directors. In addition, the Company
has purchased directors and officers insurance on behalf of all of its
directors and executive officers.
 
  The Company's Amended and Restated Certificate of Incorporation, to be
adopted prior to the closing of this offering, will additionally provide that,
to the fullest extent permitted by Delaware law, the Company's directors will
not be personally liable to the Company or its stockholders for monetary
damages for breach of their fiduciary duties as directors, except (i) for any
breach of their duty of loyalty to the Company or its stockholders, (ii) for
acts or omissions not in good faith or which involve intentional misconduct or
a knowing violation of law, or (iii) for any transactions from which the
director derives an improper personal benefit. This provision also does not
affect a director's responsibilities under any other laws, such as the federal
securities laws or state or federal environmental laws.
 
  There is no pending litigation or proceeding involving a director or officer

                             CERTAIN TRANSACTIONS
 
  In October 1993, the Company sold all rights with respect to its initial
software product, GAP, to Intellex, Inc. ("Intellex"), a corporation wholly
owned by Guy M. Lammle and Roger H. Linn, for a purchase price of $200,000.
The purchase price was paid by delivery to the Company of a promissory note,
which was paid in full in November 1994.
 
  On April 1, 1995, the Company acquired certain assets relating to the Profit
Workbench and Handbook programs and assumed certain liabilities from Intellex
in exchange for the cancellation of a $117,237 note payable by Intellex to the
Company, which arose from various intercompany transactions. The assets
acquired and liabilities assumed were recorded at their historical net book
value. The amount by which assets exceeded the liabilities assumed ($115,375)
was treated as a reduction of stockholders' equity due to the fact that the
entities were related through substantially common ownership on the date of
the transaction. The Company has incorporated the operations of Intellex into
its statement of operations from the date of acquisition, April 1, 1995. The
methodology for recording this transaction was made in accordance with
generally accepted accounting principles.
 
  During the period from February 1, 1992 through October 10, 1994, the
Company leased its principal offices from Plumtree of Colorado Springs LLC
("Plumtree LLC"), which members consist of Guy M. Lammle and Roger H. Linn and
their immediate family members. During the period from January 1, 1994 through
October 10, 1994, the lease payments made by the Company to Plumtree LLC
aggregated $378,601. On October 11, 1994, the property was sold by Plumtree
LLC to Plumtree Office Investors, Ltd. ("Plumtree Ltd."), an unaffiliated
entity, at which time the Company entered into a new lease agreement with
Plumtree Ltd. The lease agreement permitted the Company to offset against its
lease payments to Plumtree Ltd. any amounts not paid by Plumtree Ltd. to
Plumtree LLC when due under the promissory note relating to Plumtree Ltd.'s
acquisition of the property. Such promissory note has been repaid and no
offsets against such note were made. The term of the current lease expires in
October 1998; however, the Company has an option to renew the lease for either
a three year or a five year period thereafter.
 
  In February 1995, R&D Hardware Systems Company ("R&D Hardware"), the
shareholders of which are Guy M. Lammle, Roger H. Linn, various members of
each of their families and Patrick J. Becker, acquired certain assets of UDS
in exchange for $2,126,583 in cash and the assumption of liabilities of
$839,190. R&D Hardware immediately sold substantially all of the operating
assets of UDS that it had purchased to the Company for $1,869,757 cash and the
assumption of certain liabilities totalling $839,190. Among the operating
assets of UDS sold to R&D Hardware, and which R&D Hardware subsequently sold
to the Company, were rights to the SHIMS software product.
 
  During the period from January 1, 1993 through January 1, 1996, the Company
engaged in a series of ongoing transactions with R&D Hardware. These
transactions included purchases by the Company from R&D Hardware of computer
equipment for resale (aggregating $4,237,000 during the period from January 1,
1994 through January 1, 1996), equipment procurement services (aggregating
$483,000 during the period from January 1, 1994 through January 1, 1996), and
the provision by the Company to R&D Hardware of administrative services in
exchange for management fees and reimbursement of expenses (aggregating
$360,000 during the period from January 1, 1994 through January 1, 1996). The
shareholders of R&D Hardware sold substantially all of the assets of R&D
Hardware to Western Micro Technology, Inc. ("Western Micro"), a hardware
reseller, on January 2, 1996 for an aggregate purchase price of $1,000,000,
plus 125,000 shares of the common stock of Western Micro. The Company
simultaneously entered into a Value Added Reseller Agreement with Western
Micro which enables the Company to purchase hardware for resale at discounts
that vary dependent upon the aggregate volume purchased.
 
  On August 16, 1995, the Company licensed the program Manager's Handbook to
The Distribution Team, Inc. ("DT"), a corporation whose majority stockholder
is Guy M. Lammle and whose other stockholders are Gordon Graham and Scott
Stratman (who operates DT without involvement from Messrs. Graham and Lammle).
An agreement is in place which permits Mr. Stratman to acquire over time Mr.
Lammle's majority interest in DT. In exchange, DT licensed the GG Handbook, a
program developed from the Manager's Handbook, to the Company. The Company
additionally agreed to pay a royalty to DT of $2,000 per GG Handbook sold. The
Company received the right to buy out its royalty payment obligations to DT
for a payment of $500,000
 
                                      49
<PAGE>
 
less any prior $2,000 royalty payments made to DT (the "Buy-Out Right"). On
August 14, 1996, the Company exercised its Buy-Out Right on the GG Handbook.
 
  On March 14, 1996, the Company effected the Recapitalization. See
"Recapitalization." Pursuant to the Recapitalization, the Company sold 26,000
shares of its Series A Preferred Stock to a group of investors, including a
total of 15,000 shares to entities affiliated with TA Associates, Inc. and
10,000 shares to entities affiliated with Summit Partners, at an aggregate
purchase price of $26,000,000. Jacqueline C. Morby, a general partner of TA
Associates, Inc., and Gregory M. Avis, a general partner of Stamps, Woodsum &
Co., IV, the general partner of Summit Partners IV, L.P., are both directors
of the Company.
 
  As part of the Recapitalization, the Company paid $17,500,000 in cash and
issued 6,500 shares of its Series B Preferred Stock to Guy M. Lammle, the
Company's Chief Executive Officer, President and Chairman of the Board, and
persons or entities with whom he is affiliated, in exchange for all of Mr.
Lammle's previous holdings of the Company's Common Stock.
 
  Upon the closing of this offering, the outstanding Series A Preferred Stock
will automatically convert into 5,980,000 shares of Common Stock and 15,500
shares of Senior Redeemable Preferred Stock and the outstanding Series B
Preferred Stock will automatically convert into 1,495,000 shares of Common
Stock, 3,875 shares of Senior Redeemable Preferred Stock and 2,625 shares of
Junior Redeemable Preferred Stock. All shares of Senior Redeemable Preferred
Stock and Junior Redeemable Preferred Stock will be redeemed upon the closing
of this offering for total payments of $19,375,000 and $2,625,000,
respectively. See "Use of Proceeds."
 
  In connection with the Recapitalization, the Company made payments in an
aggregate amount of $7,000,000 (before withholding taxes) to certain employees
of the Company pursuant to the Company's Unit Incentive Plan, a compensation
plan under which the Company had previously made awards. The following
payments were made under the Unit Incentive Plan to executive officers of the
Company: Ms. Cunningham--$500,000; Mr. Elliott--$250,000; Mr. Becker--
$1,000,000; Mr. Watson--$750,000; and Mr. Dekker--$33,333. After receipt of
the Unit Incentive Plan payments from the Company, all recipients released the
Company from any further obligations to them under the Unit Incentive Plan and
the Company terminated the Unit Incentive Plan. The Company recognized
compensation expense of $3,196,379 and $3,803,621 in 1995 and 1996,
respectively, in connection with the Unit Incentive Plan.
 
  In connection with the Recapitalization, Guy M. Lammle entered into a non-
competition agreement with the Company (the "Non-Competition Agreement"). The
Non-Competition Agreement provides that Mr. Lammle (i) shall not disclose any
confidential information of the Company; (ii) shall return all documents
belonging to the Company upon termination of employment; (iii) shall assign
any and all proprietary rights in Company-related developments and inventions
to the Company; and (iv) until the later of March 14, 2000 or two years after
Mr. Lammle's employment with the Company is terminated, shall not engage in
any business activity the result of which is the development, manufacturing or
marketing of products or services in competition with the Company and shall
not solicit any person to leave the employment of the Company. In addition,
the Non-Competition Agreement requires the Company to pay a total of
$2,500,000 to Mr. Lammle in consideration for his execution of such agreement,
of which $1,500,000 was paid during 1996, $500,000 is required to be paid on
March 14, 1997 and $500,000 is required to be paid on March 14, 1998.
 
  As part of the Recapitalization, the Company sold 1,473,943 shares of the
Company's Common Stock (the "Lammle Shares") to Guy M. Lammle at a purchase
price of $0.217 per share, under the Stock Option Plan. The Company has a
repurchase option, which terminates entirely on March 31, 2006 (subject to
earlier termination for the Company's achievement of certain performance
targets and the redemption of the Company's redeemable preferred stock), with
respect to the Lammle Shares. Subject to adjustment for the Company's
achievement of certain performance targets and the redemption of the Company's
redeemable preferred stock, the Company's repurchase option with respect to
the Lammle Shares will lapse at a rate of 131,602 shares per quarter through
March 31, 1998, and thereafter at a rate of 13,160 shares per quarter through
March 31, 2006. Upon redemption of the Company's redeemable preferred stock in
connection with this offering, 105,281 of the Lammle Shares will vest.

                         DESCRIPTION OF CAPITAL STOCK
 
  The following description of the capital stock of the Company and certain
provisions of the Company's Amended and Restated Certificate of Incorporation
and Bylaws is a summary and is qualified in its entirety by the provisions of
the Amended and Restated Certificate of Incorporation and Bylaws, which have
been filed as exhibits to the Company's Registration Statement, of which this
Prospectus is a part.
 
  Upon the closing of this offering, the authorized capital stock of the
Company, after giving effect to the conversion of all outstanding convertible
preferred stock into Common Stock and redeemable preferred stock (and the
immediate redemption of all redeemable preferred stock), will consist of
27,000,000 shares of Common Stock, $0.01 par value per share, and 5,000,000
shares of Preferred Stock, $0.01 par value per share.
 
COMMON STOCK
 
  As of February 28, 1997, there were 9,070,331 shares of Common Stock
outstanding and held of record by 18 stockholders, assuming the conversion of
all outstanding shares of convertible preferred stock into Common Stock that
will occur upon the consummation of the offering contemplated hereby. Based
upon such number of shares deemed outstanding as of that date and giving
effect to the issuance of 4,300,000 shares of Common Stock offered hereby,
there will be 13,370,331 shares of Common Stock outstanding upon consummation
of this offering. The holder of each share of Common Stock has the right to
one vote on such matters and in such manner as may be provided by law. Holders
of Common Stock are not entitled to cumulative voting rights with respect to
the election of directors, and as a consequence, minority stockholders will
not be able to elect directors on the basis of their votes alone. Subject to
the prior rights of holders of all classes of stock at the time outstanding
having prior rights as to dividends, the holders of Common Stock are entitled
to receive, when and as declared by the Board of Directors, out of any assets
of the Company legally available therefor, such dividends as may be declared
from time to time by the Board of Directors. See "Dividend Policy." In the
event of a liquidation, dissolution or winding up of the Company, whether
voluntary or involuntary, holders of the Common Stock are entitled to share
ratably in all assets remaining after payment of liabilities and the
liquidation preference of any then outstanding Preferred Stock. Holders of
Common Stock have no preemptive rights and no right to convert their Common
Stock into any other securities. There are no redemption or sinking fund
provisions applicable to the Common Stock. All presently outstanding shares of
Common Stock are, and all shares of Common Stock to be outstanding upon
completion of this offering will be, fully paid and nonassessable.
 
PREFERRED STOCK
 
  The Board of Directors has the authority, without further action by the
stockholders, to issue up to 5,000,000 shares of Preferred Stock in one or
more series and to determine or alter the designations, preferences, and
relative, participating, optional or other rights, and such qualifications,
limitations or restrictions thereof, as shall be stated in resolutions adopted
by the Board of Directors and as may be permitted by the Delaware General
Corporation Law. The issuance of Preferred Stock could adversely affect the
voting power of holders of Common Stock and the likelihood that such holders
will receive dividend payments and payments upon liquidation and could have
the effect of delaying, deferring or preventing a change in control of the
Company. No shares of Preferred Stock will be outstanding immediately
following the closing of this offering. The Company has no present plan to
issue any shares of Preferred Stock.
 
REGISTRATION RIGHTS
 
  Holders of 7,475,000 shares of Common Stock to be issued upon conversion of
the Series A Preferred Stock and the Series B Preferred Stock have certain
rights to have the Company register shares of the Company's capital stock
owned by them ("Registrable Shares") with the Securities and Exchange
Commission. If at any time, the Company shall determine to register under the
Securities Act any shares of its Common Stock or securities convertible into
or exchangeable or exercisable for shares of Common Stock, holders of
Registrable
 
                                      53
<PAGE>
 
Shares may request (such rights may be referred to hereinafter as "Piggyback
Registration Rights") that the Company include in such registration any
Registrable Shares that they hold. In such a case, the Company will use its
best efforts to include the Registrable Shares so requested to be included in
the registration. On any two occasions (not less than six months apart), if
holders of at least 40% of the Registrable Shares so request, the Company will
use its best efforts to cause the shares so requested to be registered under
the Securities Act. If the Company becomes eligible to use Form S-3 under the
Securities Act and the holders of 20% of the Registrable Shares request that
their shares be registered, the Company will use its best efforts to register
such shares on a Form S-3 registration statement. The Company is not required
to effect more than one such Form S-3 registration in any twelve month period.
The Company's obligation to register Registrable Shares will terminate seven
years following the consummation of this offering or, commencing on the first
anniversary of the consummation of this offering, with respect to any such
holder, whenever such holder's shares can be fully transferred under
Rule 144(k) of the Securities Act. Generally, the Company is required to bear
all registration and selling expenses incurred in connection with any such
registrations. These rights are subject to certain conditions and limitations,
among them the right of the underwriters of an offering to limit the number of
shares included in such registration. In addition, holders of the 57,500
shares of Common Stock issued by the Company in connection with the Saber
Acquisition will, following this offering, have Piggyback Registration Rights
substantially identical to those provided to the holders of the Registrable
Shares issued upon conversion of the Series A Preferred Stock and Series B
Preferred Stock.
 
DELAWARE ANTI-TAKEOVER LAW AND CERTAIN CHARTER PROVISIONS
 
  The Company is subject to the provisions of Section 203 of the Delaware
General Corporation Law, an anti-takeover law. In general, the statute
prohibits a publicly-held Delaware corporation from engaging in a "business
combination" with an "interested stockholder" for a period of three years
after the date of the transaction in which the person became an interested
stockholder, unless the business combination is approved in a prescribed
manner. For purposes of Section 203, a "business combination" includes a
merger, asset sale or other transaction resulting in a financial benefit to
the interested stockholder, and an "interested stockholder" is a person who,
together with affiliates and associates, owns (or within three years prior,
did own) 15% or more of a corporation's voting stock.
 
  Upon the closing of this offering, the Company's Amended and Restated
Certificate of Incorporation (the "Certificate") will provide that any action
required or permitted to be taken by stockholders of the Company must be
effected at a duly called annual or special meeting of the stockholders and
may not be effected by a consent in writing. Special meetings of the
stockholders of the Company may be called only by the Board of Directors, the
Chairman of the Board, the Chief Executive Officer or by the holders of shares
entitled to cast not less than 50% of the votes at such a meeting. The
Company's Certificate will also provide that the authorized number of
directors may be changed only by resolution of the Board of Directors, and
that directors can only be removed for cause by a majority vote of the
stockholders. In addition, the Company's Certificate will provide for the
classification of the Board of Directors into three classes, only one of which
shall be elected at any given annual meeting. These provisions may have the
effect of delaying, deterring or preventing a change in control of the Company
or depressing the market price of Common Stock or discouraging hostile
takeover bids in which stockholders of the Company could receive a premium for
their shares of Common Stock.
 
TRANSFER AGENT AND REGISTRAR
 
  The First National Bank of Boston has been appointed as the transfer agent
and registrar for the Company's Common Stock.

                        SHARES ELIGIBLE FOR FUTURE SALE
 
  The sale of a substantial number of shares of Common Stock in the public
market following this offering could adversely affect the market price of the
Common Stock. Upon completion of this offering, the Company will have
outstanding an aggregate of 13,370,331 shares of Common Stock assuming (i) no
exercise of the Underwriters' over-allotment option, (ii) no exercise of
outstanding options and (iii) the automatic conversion of all outstanding
shares of the Company's convertible preferred stock. Of these shares, the
4,300,000 shares of Common Stock sold in this offering will be freely tradable
without restriction or further registration under the Securities Act, unless
such shares are held by "affiliates" of the Company, as that term is defined
under the Securities Act and the Regulations promulgated thereunder.
 
  The remaining 9,070,331 shares of Common Stock are "Restricted Shares" and
are subject to restrictions under the Securities Act. All of the Restricted
Shares are subject to lock-up agreements under which the holders have agreed
not to sell or otherwise dispose of any of their shares for a period of 180
days after the date of this Prospectus except in connection with the exercise
of the Underwriters' over-allotment option relating to this offering or with
the prior written consent of Montgomery Securities. Beginning 180 days after
the date of the Prospectus, approximately 8,422,535 Restricted Shares will
become available for sale in the public market pursuant to Rule 144 or Rule
701 under the Securities Act. By January 1998, up to an additional 318,791
shares will become eligible for sale in the public market pursuant to Rule 144
or Rule 701 under the Securities Act. The remaining Restricted Shares will
become eligible for resale pursuant to Rule 144 or Rule 701 under the
Securities Act at various times starting in March 1998 as the Company's
repurchase option for the Restricted Shares lapses. During the period from
March 1998 through March 2004, certain holders of the Restricted Shares of
Common Stock, or their transferees, will be entitled to certain rights with
respect to the registration of such shares under the Securities Act.
Registration of such shares under the Securities Act would result in such
shares becoming freely tradable without restriction under the Securities Act
(except for shares purchased by affiliates) immediately upon effectiveness of
such registration. See "Description of Capital Stock--Registration Rights."
 
  In general, under Rule 144 as currently in effect, a person (or persons
whose shares are aggregated), including an affiliate, who has beneficially
owned restricted shares for at least one year is entitled to sell, within any
three-month period commencing 90 days after the effective date of this
registration statement (the "Effective Date"), a number of shares that does
not exceed the greater of (i) 1% of the then outstanding shares of Common
Stock (approximately 133,703 shares immediately after this offering) or (ii)
the average weekly trading volume in the Common Stock during the four calendar
weeks preceding such sale, subject to the filing of a Form 144 with respect to
such sale and certain other limitations and restrictions. In addition, a
person who is not deemed to have been an affiliate of the Company at any time
during the 90 days preceding a sale, and who has beneficially owned the shares
proposed to be sold for at least two years, would be entitled to sell such
shares under Rule 144(k) without regard to the volume limitations described
above.
 
  Any employee, officer, director or consultant of the Company who purchased
his or her shares pursuant to a written compensatory plan or contract is
entitled to rely on the resale provisions of Rule 701, which permit non-
affiliates to sell their Rule 701 shares without having to comply with the
public-information, holding-period, volume-limitation or notice provisions of
Rule 144 and permit affiliates to sell their Rule 701 shares without having to
comply with Rule 144's holding period restrictions, in each case commencing 90
days after the Effective Date.
 
  Promptly after the Effective Date, the Company intends to file a
registration statement under the Securities Act to register shares of Common
Stock reserved for issuance under the Stock Option Plan and the Purchase Plan,
thus permitting the resale of such shares by non-affiliates in the public
market without restriction under the Securities Act. Such registration
statement will become effective immediately upon filing. Shares registered
under such registration statement will, subject to Rule 144 volume limitations
applicable to affiliates, be available

for sale in the public market, unless such shares are subject to vesting
restrictions with the Company or the lock-up agreements described above. At

outstanding under the Stock Option Plan; no shares of Common Stock had been
purchased under the Purchase Plan.
 
  Prior to this offering, there has been no public market for the Common Stock
of the Company, and any sale of substantial amounts in the open market may
adversely affect the market price of the Common Stock offered hereby.

  The Representatives have advised the Company that the Underwriters propose
initially to offer the shares of Common Stock to the public on the terms set
forth on the cover page of this Prospectus. The Underwriters may allow to
selected dealers a concession of not more than $   per share, and the
Underwriters may allow, and such dealers may reallow, a concession of not more
than $   per share to certain other dealers. After this offering, the offering
price and other selling terms may be changed by the Representatives. The
Common Stock is offered subject to receipt and acceptance by the Underwriters,
and to certain other conditions, including the right to reject orders in whole
or in part.
 
  The Company has granted an option to the Underwriters, exercisable during
the 30-day period after the date of this Prospectus, to purchase up to a
maximum of 645,000 additional shares of Common Stock to cover over-allotment
options, if any, at the same price per share as the initial 4,300,000 shares
to be purchased by the Underwriters. To the extent the Underwriters exercise
this over-allotment option, each of the Underwriters will be committed,
subject to certain conditions, to purchase such additional shares in
approximately the same proportion as set forth in the above table.
 
  The Underwriting Agreement provides that the Company will indemnify the
Underwriters against certain liabilities, including liabilities under the

may grant options or issue stock upon exercise of new or outstanding options
pursuant to the Stock Option Plan and the Purchase Plan. Montgomery Securities
may, in its sole discretion and at any time without notice, release all or any
portion of the securities subject to these lock-up agreements.

expect to make sales to accounts over which they exercise discretionary
authority in excess of 5% of the number of shares of Common Stock offered

  Prior to this offering, there has been no public market for the Common
Stock. Consequently, the initial public offering price will be determined by
negotiations between the Company and the Representatives. Among the factors to
be considered in such negotiations will be the history of, and the prospects
for, the Company and the industry in which it competes, an assessment of the
Company's management, its past and present operations, its past and present
financial performance, the prospects for future earnings of the Company, the
present state of the Company's development, the general condition of the
securities markets at the time of this offering and the market prices of and
demand for publicly traded common stock of comparable companies in recent
periods and other factors deemed relevant.

                   REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To NxTrend Technology, Inc.:
 
  We have audited the accompanying balance sheets of NxTrend Technology, Inc.
(formerly R&D Systems Company), a Delaware corporation, as of December 31,
1995 and 1996, and the related statements of income; mandatorily redeemable
preferred stock and stockholders' equity (deficit); and cash flows for each
year in the three-year period ended December 31, 1996. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.
 
  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
 
  In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of NxTrend Technology, Inc.,
as of December 31, 1995 and 1996, and the results of its operations and its
cash flows for each year in the three-year period ended December 31, 1996 in
conformity with generally accepted accounting principles.

(1) ORGANIZATION
 
  NxTrend Technology, Inc. (formerly known as R&D Systems Company), a Delaware
corporation (the "Company"), is a leading provider of enterprise-wide software
solutions that address the critical business information requirements of
durable goods wholesale distributors. The Company develops, licenses, and
supports proprietary management and accounting software products, which are
marketed under the names "Trend" and "SHIMS." The Company also provides
business consulting services, implementation services, modification services,
and training for its customers. In connection with its software license
arrangements, the Company also sells, installs, and supports third-party
software and computer equipment. The Company operates primarily in the United
States. The Company's products and services are marketed primarily through the
Company's direct sales force and, to a significantly lesser degree,
independent resellers. In March 1996, the Company changed its state of
organization from Colorado to Delaware.
 
  On March 14, 1996, the Company completed a recapitalization (the
"Recapitalization") whereby the following transactions occurred:
 
  . The Company issued 26,000 shares of Series A Mandatorily Redeemable,
    Convertible Preferred Stock for $26,000,000 in cash ($1,000 per share).
 
  . The Company borrowed $26,000,000 under a financing facility (see Note 7).
 
  . 18,400 shares of the Company's common stock were purchased by the Company
    from its founders for $49,000,000 in cash, and retired.
 
  . 4,600 shares of the Company's common stock owned by a founder were
    exchanged for 6,500 shares of the Company's Series B Mandatorily
    Redeemable, Convertible Preferred Stock, with a redemption value of
    $6,500,000 ($1,000 per share).
 
  . 1,473,943 shares of common stock to a founder for $320,000 in cash. This
    stock is subject to certain restrictions (see Note 9).
 
(2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
 Revenue Recognition
 
  The Company generates revenue from four sources: (i) fees for the initial
license of the Company's proprietary software products and software products
developed by third parties, (ii) annual license fees which give the customer
the right to the continued use of the software and to updates of the Company's
software when issued by the Company and telephone support fees paid by the
customer, in advance, generally on an annual basis, (iii) implementation,
training and consulting services, and (iv) sales of third party hardware.
 
  Revenue from the initial license fees of the Company's software products and
third party software, and related sales of hardware, are recognized upon
receipt of an executed license agreement and delivery and installation of the
software and hardware to the customer, provided that the collection of the
license fee is probable and the Company has satisfied all significant
performance obligations, unless the terms of the license agreement contains
non-standard customer acceptance criteria. Until all such significant
performance obligations and all significant customer acceptance criteria are
satisfied, software and hardware revenue and the costs of the related third-
party software and hardware are deferred. Deferred third-party software and
hardware costs totaled approximately $1,037,000 and $52,000 at December 31,
1995 and 1996, respectively, and are presented as a reduction of deferred
revenue in the accompanying balance sheets.
 
  Revenue from annual license fees and maintenance and support agreements are
deferred and recognized ratably over the term of the agreements, which are
typically one year. Implementation, training, consulting and
 
                                     F-10

                  NOTES TO FINANCIAL STATEMENTS--(CONTINUED)
 
other services revenue is generally recognized as the services are performed.
Consulting and implementation services are typically performed under separate
service agreements and are performed on a time and materials basis.
 
  If hardware is sold apart from software, hardware revenue is recognized when
delivered to the customer.
 
  Agreements with distributors of the Company's products typically do not
include any rights of return, commitments to provide updates to the
distributor or provisions for the future adjustment of the selling price. The
Company recognizes revenue from these transactions at the time the products
are shipped to the distributor for installation of the software products at
the end-user site. Telephone support is provided directly to the end-user by
the distributor. The Company receives a portion of the annual license fees
charged to the end-user by the distributor for the continued use and
enhancement of the software, and recognizes such annual license fees ratably
over the appropriate period, typically one year.
 
  The Company typically requires minimum deposits of approximately 25% of the
contract value upon execution of the software license arrangement, which are
recorded as deposit liabilities until significant performance has commenced on
the contract.
 
 Cost of Revenue
 
  Cost of software license fee revenue includes the cost of media, product
packaging, third-party software license fees and other production costs.
 
  Costs of annual licenses, support fees and services consists primarily of
salaries, benefits and allocated overhead costs related to consulting,
training and customer support personnel.
 
 Concentrations of Credit Risk
 
  Financial instruments which potentially subject the Company to
concentrations of credit risk are primarily accounts receivable and cash
equivalents. The Company's customers generally operate as wholesale
distributors of durable goods; accordingly, the Company's accounts receivable
are concentrated in wholesale distributors. The Company performs initial and
ongoing credit evaluations of its customers' financial condition and generally
requires no collateral, except deposits as discussed above. The Company
retains title or a security interest in all third party hardware until the
full purchase price of the hardware has been paid. For the years ended
December 31, 1996 and 1995, no single customer accounted for more than 10% of
the Company's revenue. For the year ended December 31, 1994, one customer
accounted for 12% of the Company's revenue. The Company's cash equivalents are
primarily invested in money market securities. The Company maintains the
majority of its cash balances with financial institutions in the form of
demand deposits and money market accounts.
 
  The Company has no significant off-balance-sheet concentrations of credit
risk such as foreign exchange contracts, option contracts or other foreign
currency hedging arrangements.
 
 
 Cash Equivalents
 
  For purposes of reporting cash flows, the Company considers cash on hand,
demand deposits in banks, and all highly liquid investments with original
maturities of three months or less to be cash and cash equivalents.
 
 Inventories
 
  Inventories consist primarily of computer equipment and third-party software
and are stated at the lower of cost (average cost method) or market.

 Software Development Costs
 
  Research and development costs are expensed as incurred and consist of
salaries and other direct costs. Capitalization of software development costs
commences upon the establishment of technological feasibility of the product.
The Company's software products are deemed to be technologically feasible at
the point a working model of the software product is developed, which is
generally at or near the point the Company commences field testing of the
software. Through December 31, 1996, for the products developed by the
Company, the period from field testing to the general customer release of the
software has been brief and, accordingly, the Company has not capitalized any
qualifying software development costs in the accompanying financial
statements.
 
 
 Other Assets
 
Other assets are comprised of the following:

  The excess of the purchase price paid over net tangible assets acquired and
non-compete payments to a stockholder are being amortized using the straight-
line method over periods of three and four years, respectively. The deferred
debt issuance costs are being amortized using the effective interest rate
method over the term of the debt. Licensed software is being amortized using
the straight-line method over a period of three years.
 
 Fair Market Value of Financial Instruments
 
  Financial instruments include cash and cash equivalents, accounts receivable
and long-term obligations. The carrying amounts for the cash and cash
equivalents and accounts receivable approximate fair market value because of
the short maturity of these instruments. The carrying amount of the long-term
obligation approximates their fair market value because the variable interest
rates under the debt agreement are short-term in nature.
 
 Income Taxes
 
  The Company accounts for income taxes in accordance with Statement of
Financial Accounting Standards No. 109, Accounting for Income Taxes ("SFAS No.
109"). SFAS No. 109 requires recognition of deferred income tax assets and
liabilities for the expected future income tax consequences, based on enacted
tax laws, of temporary differences between the financial reporting and tax
basis of assets, liabilities and carryforwards. SFAS No. 109 requires
recognition of deferred tax assets for the expected future effects of all
deductible temporary differences, loss carryforwards and tax credit
carryforwards. Deferred tax assets are then reduced, if deemed necessary, by a
valuation allowance for the amount of any tax benefits which, more likely than
not, based on current circumstances, are not expected to be realized. Income
tax provision is the tax payable for the period and the change during the
period in deferred tax assets and liabilities.

 Use of Estimates
 
  The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions. Such estimates and assumptions affect the reported amounts of
assets and liabilities as well as disclosures of contingent assets and
liabilities at the date of the financial statements, and the reported amounts
of revenue and expenses during the reporting period. Actual results could
differ from those estimates.
 
 Unaudited Pro Forma Net Income Per Common Share
 
  The Company's historical capital structure is not indicative of its
prospective structure due to the automatic conversion of all shares of
mandatorily redeemable, convertible preferred stock into mandatorily
redeemable preferred stock and common stock concurrent with the closing of the
Company's anticipated initial public offering. Accordingly, historical net
income per common share is not considered meaningful as it would differ
materially from the pro forma net income per common share and common stock
equivalent shares given the contemplated changes in the capital structure of
the Company.
 
  Pro forma net income per common share and equivalents has been computed
using the sum of the weighted average number of shares of common stock and
common stock equivalent shares from convertible preferred stock and options.
Pursuant to Securities and Exchange Commission Staff Accounting Bulletin No.
83, common stock and common stock equivalent shares issued by the Company
(including the common stock equivalents of securities issued in the
Recapitalization) at prices significantly below the assumed public offering
during the twelve month period prior to the filing of the registration
statement related to the Company's proposed initial public offering (using the
treasury stock method and an assumed offering price of $13 per share, which
may not be reflective of the actual offering price) have been included in the
calculation as if they were outstanding for all periods.
 
  As a portion of the proceeds of the offering contemplated by this Prospectus
will be used to repay approximately $19,500,000 in bank debt related to the
Facility (Note 7) and to redeem $22,000,000 of Senior and Junior Mandatorily
Redeemable Preferred Stock (Note 8), the following pro forma information for
the year ended December 31, 1996, is presented, assuming that bank debt was
repaid at the inception of the facility:

  If the offering contemplated by the Prospectus is consummated, all of the
outstanding shares of Series A and B Mandatorily Redeemable, Convertible
Preferred Stock will be automatically converted into shares of common stock
and immediately redeemable Senior and Junior Mandatorily Redeemable Preferred

Convertible Preferred Stock into 7,475,000 shares of common stock, 15,500
shares of Senior Redeemable Preferred Stock and 6,500 shares of Junior
Mandatorily Redeemable Preferred Stock. Shares of Senior and Junior
Mandatorily Redeemable Preferred Stock must be immediately redeemed for
$22,000,000 in cash in the event of a qualified initial public offering, such
as that contemplated by this Prospectus. Such redemption has not been
reflected in the unaudited, pro forma balance sheet as of December 31, 1996.
 
 Stock Split and Changes In Authorized Shares
 
  The Company has approved a 2.3-for-1 share common stock split to be
effective upon the effective date of the Registration Statement on Form S-1
filed by the Company with the Securities and Exchange Commission. Common stock
and equivalent amounts, and per share amounts have been adjusted retroactively
to reflect such stock split. The Company has also approved an increase in the
number of authorized shares of common stock to 31,895,500, effective as of the
Registration Statement effective date. Subsequently, the Company intends to
decrease the number of common shares authorized to 27,000,000 effective upon
the closing of the offering contemplated by such Registration Statement.
 
 Stock Compensation Plans
 
  The Company applies APB Opinion No. 25, Accounting for Stock Issued to
Employees, in accounting for its stock option and other stock-based plans for
employees and directors. The Company has adopted the disclosure provisions of
SFAS No. 123, Accounting for Stock-Based Compensation for such options and
stock-based plans for employees and directors (Note 9).
 
 
 Other, Net
 
  For the years ended December 31, 1994, 1995 and 1996, other income was
primarily comprised of referral fees paid by third-party software vendors.
Other income was also comprised of a gain on a legal settlement for the year
ended December 31, 1994.
 
 Adoption of New Accounting Standard
 
  The Company has adopted Statement of Financial Accounting Standards No. 121,
Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets
to Be Disposed Of. Such adoption did not have a material effect on the
Company's financial position or results of operations.
 
(3) ACQUISITIONS
 
  In February 1995, an affiliate at that time (through substantially common
ownership) of the Company acquired certain assets (including SHIMS) in the
bankruptcy proceeding of Ultimate Data Systems, Inc. ("UDS"), a developer of
management and accounting software used by wholesale distributors, in exchange
for cash of $2,127,000 and the assumption of certain liabilities totaling
$839,000. This affiliate immediately sold substantially all of the operating
assets purchased from UDS to the Company for $1,870,000 in cash and assumption
of $839,000 of related operating liabilities. The Company has included the
operations of UDS in its statement of operations from February 1995.
 
  The acquisition was recorded in accordance with the purchase method of
accounting for business combinations. The tangible assets acquired and
liabilities assumed were recorded at their estimated fair values at the date
of acquisition and the remainder of the purchase price, $1,669,000, was
assigned to intangibles. Intangibles acquired in the transaction, primarily
software and customer lists, are being amortized over three years.

  The above amounts reflect adjustments for amortization of goodwill and
depreciation on revalued fixtures and equipment.
 
  In December 1996 and January 1997, the Company signed letters of intent to
acquire three companies. The Company entered into letters of intent to acquire
substantially all of the assets and assume certain liabilities of the
Company's primary independent reseller in Canada for $250,000 in cash and
63,888 shares of the Company's common stock, to acquire certain assets of an
independent reseller in Minnesota for approximately $1,300,000 in cash plus
the assumption of certain liabilities and 57,500 shares of the Company's
common stock, and to acquire certain assets of Goretek Data Systems, Inc. for
approximately $1,000,000 in cash and the assumption of certain liabilities.
 
(4) RELATED PARTY TRANSACTIONS
 
  During the years ended December 31, 1994 and 1995, the Company purchased
computer equipment for resale of approximately $1,642,000 and $2,595,000,
respectively, from a computer equipment dealer then related through
substantially common ownership. In 1994 and 1995, this related entity also
provided equipment procurement services for which the Company paid the related
entity $200,000 and $283,000, respectively. Additionally, at December 31, 1995
the Company had accounts receivable of approximately $14,000, and accounts
payable of approximately $232,000, respectively, with this related entity.
Management fees and expense reimbursements received from this entity amounted
to approximately $170,000 and $190,000 for 1994 and 1995, respectively. As of
January 1996, this entity was sold to an unrelated third party.
 
  In connection with the Recapitalization, the two Founders of the Company
entered into non-competition agreements with the Company. As part of one such
agreement, the Company paid $1,500,000 to one of the Founders who remains a
stockholder of the Company and, contingent on his continued employment with
the Company after the Recapitalization, agreed to pay him an additional
$500,000 on March 14, 1997 and 1998, respectively.
 
  In August 1996, the Company exercised its buy-out right on a cross license
agreement that provided for royalty payments to an entity partially owned by
one of the Founders. The buy-out right payment of $456,000 was net of previous
royalties paid under the cross license of $44,000. The buy-out amount is
included in other assets and is being amortized over three years.
 
  In early 1995, Intellex, Inc. ("Intellex"), an entity then affiliated
through substantially common ownership, sold its principal operating assets
and ceased operations shortly thereafter. Effective April 1, 1995, the Company
acquired the remaining operating assets and assumed certain liabilities, which
were recorded by the Company at their historical net book value. The amount by
which assets acquired were exceeded by the liabilities assumed ($115,000), was
treated as an effective distribution to the Company's stockholders, and
charged to retained earnings. The Company has incorporated the operations of
Intellex into its statements of operations from April 1, 1995.

(6) LEASES
 
  The Company leased space from a related party through mid-October 1994, at
which time the building was sold by the related party to an unrelated third
party. The Company entered into a new lease for the building with the third
party which expires in October 1998. The Company also leases space under
various leases that expire in 1998. Future minimum annual rental payments due
under these leases and other non-related party noncancelable operating leases
are as follows:

(7) FINANCING FACILITIES
 
  On March 14, 1996, the Company entered into a financing facility (the
"Facility") including a secured term loan ("Term Loan") of $25,000,000 and a
secured revolving credit line ("Revolving Loan"). The Revolving Loan provides
for a maximum outstanding balance of $5,000,000. The Facility expires on
December 31, 2000, or earlier based on certain provisions included in the
Facility. Additionally, the principal balance may be prepaid, without penalty.
Interest accrues on the Term Loan and the outstanding balance of the Revolving
Loan at variable rates based on the terms of the Facility. At December 31,
1996, the weighted average interest rate was 7.78 percent and 8.75 percent on
the Term Loan and the outstanding balance of the Revolving Loan, respectively.
Principal and interest payments are due quarterly. As of December 31, 1996,
$19,000,000 and $500,000 were outstanding under the Term Loan and the
Revolving Loan, respectively. Borrowings under the Facility are secured by
substantially all of the assets of the Company.
 
  The Facility requires the Company to maintain, among other restrictions, a
minimum interest coverage ratio, a minimum debt service coverage ratio, and a
maximum ratio of total indebtedness for borrowed money to earnings. The
Company was in compliance with the covenants as of December 31, 1996.

(8) MANDATORILY REDEEMABLE PREFERRED STOCK
 
  The Company is authorized to issue 54,500 shares of designated preferred
stock, par value of $0.01 per share, consisting of 26,000 shares of Series A
Mandatorily Redeemable, Convertible Preferred Stock ("Series A Preferred"),
6,500 shares of Series B Mandatorily Redeemable, Convertible Preferred Stock
("Series B Preferred"), 19,375 shares of Senior Mandatorily Redeemable
Preferred Stock ("Senior Redeemable Preferred"), and 2,625 shares of Junior
Mandatorily Redeemable Preferred Stock ("Junior Redeemable Preferred"). The
Company is also authorized to issue 50,000 shares of undesignated preferred
stock.
 
  The relative rights and privileges of each class of preferred stock are
summarized as follows:
 
 Series A Mandatorily Redeemable, Convertible Preferred Stock
 
  Holders of Series A Preferred vote together with holders of Series B
Preferred as a single class on an as-if-converted to common stock basis. In
addition, the holders of Series A Preferred, voting as a separate class, are
entitled to elect two directors to the Company's Board of Directors. Dividends
are payable only when, if, and in amounts approved by the Board of Directors
in the same amounts as are available to holders of common stock, on an as-if-
converted basis. Upon a liquidation, merger, sale, change in control of the
Company or redemption or repurchase of shares representing a majority of the
voting power of the outstanding shares of capital stock of the Company, the
holders of Series A Preferred are entitled to a senior liquidation preference,
in parity with holders of Series B Preferred and Senior Redeemable Preferred,
and in priority to holders of Junior Redeemable Preferred and common stock, in
the amount of $596 per share ($15,500,000 at December 31, 1996), or if
proceeds are insufficient, to share ratably with holders of Series B Preferred
and the Senior Redeemable Preferred. If the liquidation preferences due to
Series A and B Preferred and Senior Redeemable Preferred are paid in full, the
holders of Series A Preferred receive a junior liquidation preference of the
greater of $404 per share ($10,500,000 at December 31, 1996) or the ratable
share of amounts payable to holders of all shares of the Company's capital
stock, on an as-if-converted to common stock basis, once the holders of Series
B Preferred have received in full certain amounts, as discussed below. Holders
of Series A Preferred can convert their shares of Series A Preferred into
5,980,000 shares of common stock and 15,500 shares of Senior Redeemable
Preferred. All shares of Series A Preferred are automatically converted upon
the election of two-thirds of the shares of Series A Preferred to convert or
the closing of a qualified initial public offering. In the case of conversion
upon such an initial public offering, the holders of Series A Preferred would
not receive shares of Senior Redeemable Preferred, but rather would receive an
aggregate of $15,500,000 in cash. The Series A Preferred is redeemable at the
election of the holders of Series A Preferred and Series B Preferred, voting
together as a single class on an as-if-converted to common stock basis, if
two-thirds of such class so elect. The redemption amount of $26,000,000 is
payable in three equal installments on March 31, 2001, 2002 and 2003. Until
such redemption is made, no dividends may be paid on any other class of stock,
nor can shares of any other class be repurchased or redeemed. If funds are
insufficient to redeem the Series A Preferred, the unpaid redemption amount
bears interest at the greater of 12% or 5% over a prime rate. Holders of
Series A Preferred are also entitled to share in residual distributions, if
any, on an as-if-converted basis.

 Series B Mandatorily Redeemable, Convertible Preferred Stock
 
  Holders of Series B Preferred vote together with holders of Series A
Preferred as a single class on an as-if-converted to common stock basis.
Dividends are payable only when, if, and in amounts approved by the Board of
Directors in the same amounts as are available to holders of common stock, on
an as-if-converted basis. Upon a liquidation, merger, sale, change in control
of the Company or redemption or repurchase of shares representing a majority
of the voting power of the outstanding shares of capital stock of the Company,
the holders of Series B Preferred are entitled to liquidation preferences, in
parity with holders of Series A Preferred and Senior Redeemable Preferred, and
in priority to holders of Junior Redeemable Preferred and common stock, in the
amount of $596 per share ($3,875,000 at December 31, 1996), or if proceeds are
insufficient, to share ratably with holders of Series A Preferred and the
Senior Redeemable Preferred. If the senior liquidation preferences due to
Series A ($15,500,000 at December 31, 1996) and Series B ($3,875,000 at
December 31, 1996) Preferred and Senior Redeemable Preferred ($0 at
December 31, 1996), are paid in full and the junior liquidation preference due
the holders of Series A Preferred ($10,500,000 at December 31, 1996) is paid
in full, the holders of Series B Preferred receive the greater of $404 per
share ($2,625,000 at December 31, 1996) or the ratable share of amounts
payable to holders of Series A Preferred, Series B Preferred, and common stock
on an as-if-converted to common stock basis. Holders of Series B Preferred are
also entitled to share in residual distributions, if any, on an as-if-
converted to common stock basis. Holders of Series B Preferred can convert
their shares of Series B Preferred into 1,495,000 shares of common stock,
3,875 shares of Senior Redeemable Preferred and 2,625 shares of Junior
Redeemable Preferred. All shares of Series B Preferred are automatically
converted upon the election of a majority of the shares of Series B Preferred
to convert, the election of two-thirds of the shares of Series A Preferred to
convert their shares of Series A Preferred into common stock or the closing of
a qualified initial public offering. In the case of conversion upon such an
initial public offering, the holder of Series B Preferred would not receive
shares of Senior and Junior Redeemable Preferred, but rather would receive
$6,500,000 of cash. The Series B Preferred is redeemable at the election of
the holders of Series A Preferred and Series B Preferred, voting together as a
single class on an as-if-converted basis, if two-thirds of such class so
elect. The redemption amount of $6,500,000 is payable in three equal
installments on March 31, 2001, 2002 and 2003. Until such redemption is made,
no dividends may be paid on any other class of stock, nor can shares of any
other class be repurchased or redeemed, except with regard to payments
required for Series A Preferred. If funds are insufficient to redeem the
Series B Preferred, the unpaid redemption amount bears interest at the greater
of 12% or 5% over a prime rate.
 
 Senior Mandatorily Redeemable Preferred Stock
 
  Senior Redeemable Preferred has no voting rights. Dividends will accrue at
the rate of $50 per share per annum, cumulatively, from and after the date
upon which two-thirds of the shares of Series A Preferred have been converted.
Upon liquidation, holders of Senior Redeemable Preferred are entitled to
$1,000 per share on parity with senior liquidation amounts due to holders of
Series A and B Preferred. Senior Redeemable Preferred must be redeemed in the
amount of $19,375,000 immediately upon a qualified initial public offering, or
in equal installments on March 31, 2001, 2002 and 2003. If funds are
insufficient to redeem the Senior Redeemable Preferred, the unpaid redemption
amount bears interest at the greater of 12% or 5% over a prime rate.
 
 Junior Mandatorily Redeemable Preferred Stock
 
  Junior Redeemable Preferred has no voting rights. Dividends will accrue at
the rate of $50 per share, cumulatively, from and after the date upon which
two-thirds of the shares of Series A Preferred have been converted. Upon
liquidation, holders of Junior Redeemable Preferred are entitled to $1,000 per
share after holders of Series A and B Preferred and Senior Redeemable
Preferred have received their total liquidation preference. Junior Redeemable
Preferred must be redeemed in the amount of $2,625,000 immediately upon a

qualified initial public offering which meets certain criteria or in equal
installments on March 31, 2004, 2005 and 2006. However, no redemption can be
made of Junior Redeemable Preferred until all amounts due Series A Preferred
and Series B Preferred and Senior Redeemable Preferred have been paid by the
Company. If funds are insufficient to redeem the Junior Redeemable Preferred,
the unpaid redemption amount bears interest at the greater of 12% or 5% over a
prime rate.
 
(9) COMMON STOCKHOLDERS' EQUITY (DEFICIT)
 
 1996 Stock Option and Grant Plan
 
  On March 14, 1996, the Company's 1996 Stock Option and Grant Plan (as
amended, the "Plan") was adopted by the Board of Directors. The Plan provides
for the grant of incentive stock options to employees (including officers and
employee--directors) nonstatutory stock options (as defined by the Internal
Revenue Code and regulations), and restricted stock awards or issuances to
employees, directors and consultants. The purchase price of shares subject to
an incentive stock option or nonqualified stock option will be the fair market
value of the Company's common stock on the date the option is granted. If the
grantee owns more than 10% of the total combined voting power of all classes
of stock on the date of grant, the purchase price of the shares subject to a
nonqualified stock option shall be at least 110% of the fair market value at
the date of grant and the exercise term will be up to five years from the date
of grant. All incentive options granted under the Plan are exercisable up to
10 years from the date of grant. As of December 31, 1996, there were 3,053,169
shares of common stock reserved for issuance under the Plan, of which
1,473,943 had been issued as restricted common stock and 1,002,800 had been
issued as options to purchase shares of common stock.
 
  All outstanding options vest over a four to nine year period. The vesting of
a portion of these options can be accelerated if certain conditions are met.
 
 Restricted Stock
 
  In March, 1996, the Company granted 1,473,943 shares of restricted common
stock under the Plan. The holder of such shares of restricted common stock,
who is an executive of the Company, has entered into a stock restriction and
repurchase agreement under which the Company has the right to repurchase
unvested common stock at the original issuance price upon termination of this
individual's business relationship with the Company. Restrictions on these
common stock lapse over a nine-year period, which period is subject to
acceleration under certain conditions. At December 31, 1996, restrictions had
lapsed with regard to 394,806 of such shares.
 
 
 Statement of Financial Accounting Standards No. 123 ("SFAS 123")
 
  SFAS 123, "Accounting for Stock-Based Compensation," defines a fair value
based method of accounting for employee stock options or similar equity
instruments. However, SFAS 123 allows the continued measurement of
compensation cost for such plans using the intrinsic value based method
prescribed by APB Opinion No. 25, "Accounting for Stock Issued to Employees"
("APB 25"), provided that pro forma disclosures are made of net income or loss
and net income or loss per share, assuming the fair value based method of SFAS
123 had been applied. The Company has elected to account for its stock-based
employee and director compensation plans under APB 25 and related
interpretations. For purposes of the pro forma disclosures presented below,
the Company has computed the fair values of all options granted under the Plan
during 1996, using the Black-Scholes pricing model and the following weighted
average assumptions:

                  NOTES TO FINANCIAL STATEMENTS--(CONTINUED)
 
  To estimate lives of options for this valuation, it was assumed that options
will be exercised upon becoming fully vested and the Company had completed an
initial public offering of its common stock. All options are initially assumed
to vest. Cumulative compensation costs recognized in pro forma net income or
loss with respect to options that are forfeited prior to vesting is adjusted
as a reduction of pro forma compensation expense in the period of forfeiture.
Because the Company's common stock is not yet publicly traded, the expected
market volatility was based on one other company deemed to have
characteristics similar to the Company for periods subsequent to their initial
public offering. Actual volatility of the Company's common stock may vary.
Fair value computations are highly sensitive to the volatility factor assumed;
the greater the volatility, the higher the computed fair value of options
granted.
 
  The total fair value of options granted under the Plan was computed to be
approximately $367,000 for the year ended December 31, 1996. These amounts are
amortized ratably over the vesting periods of the options or recognized at
date of grant if no vesting period is required. Pro forma stock-based
compensation, net of the effect of forfeitures, was $46,000 for 1996.
 
  A summary of stock options under the Plan as of December 31, 1996 and
changes during the year then ended is presented below:

(11) PROFIT SHARING PLAN
 
  The Company maintains a profit sharing plan, including a qualified deferral
arrangement as described in Section 401(k) of the Internal Revenue Code,
covering substantially all full-time employees who meet certain minimum age
and employment requirements. Under the plan, the Company may declare a profit
sharing contribution of up to 15% of a participant's compensation, and/or a
discretionary match of a percentage of participant deferrals. Profit sharing
contributions of $302,000, $640,000 and $0 were authorized for the years ended
December 31, 1994, 1995 and 1996, respectively.
 
(12) UNIT INCENTIVE PLAN
 
  Effective January 1, 1995, the Company's stockholders approved a Unit
Incentive Plan (the "UIP") for the purpose of motivating and retaining key
employees of the Company. Under the terms of the UIP, the Company granted
stock incentive units equal, in the aggregate, to 10% of the Company's
outstanding common stock. Upon vesting, these units entitled the holders to
cash payments equal to 100% of the fair market value of shares representing
10% of the Company's outstanding common stock. At each reporting date, the
Company recorded a noncash charge to operations over the vesting period of the
units for the difference between the grant price (which was zero) and the
estimated fair market value of the Company's common stock at the reporting
date. The units vested ratably over five years and accelerated if certain
events occur, including 100% vesting if more than 50% change of the ownership
of the Company's common stock occurred. At December 31, 1995, based on the
Company's estimates of the fair market value of the Company's common stock,
the Company recorded an

amount payable related to this plan of $3,196,000. On March 14, 1996, as a
result of the Recapitalization, 100% of the UIP units vested and $7,000,000
was paid to the participants of the UIP based on units held by each
participant. The Company had recorded compensation expense related to the UIP
of $3,196,000 at December 31, 1995 and on March 14, 1996, recorded the
remaining $3,804,000. Because this plan has been terminated, it was not
considered for the pro forma SFAS 123 disclosures presented in Note 9.
 
(13) CONTINGENCIES
 
  The Company is subject to various claims and business disputes in the
ordinary course of business. While the outcome of these matters cannot be
predicted with certainty, management anticipates that the ultimate outcome of
these issues will not have a material impact on the financial statements.
 
(14) SUBSEQUENT EVENT
 
  On January 21, 1997, the Board of Directors authorized management of the
Company to file a Registration Statement with the Securities and Exchange
Commission which, once effective, may permit the Company to sell shares of its
common stock to the public.

ITEM 14. INDEMNIFICATION OF OFFICERS AND DIRECTORS.
 
  Under Section 145 of the Delaware General Corporation Law ("Delaware Law"),
the Registrant has broad powers to indemnify its directors and officers
against liabilities they may incur in such capacities, including liabilities
under the Securities Act of 1933, as amended (the "Securities Act"). The
Registrant's Bylaws provide that the Registrant will indemnify each of its
directors and executive officers to the fullest extent not prohibited by
Delaware law, provided that such person acted in good faith and in a manner
such person reasonably believed to be in or not opposed to the best interests
of the Registrant and, with respect to any criminal proceeding, had no
reasonable cause to believe his or her conduct was unlawful. The Registrant's
Bylaws also provide that the Company may indemnify other officers, employees
and other agents of the Company as set forth in the Delaware Law.
 
  The Registrant's Certificate of Incorporation provides for the elimination
of liability for monetary damages for breach of the directors' fiduciary duty
of care to the Registrant and its stockholders. These provisions do not
eliminate the directors' duty of care and, in appropriate circumstances,
equitable remedies such an injunctive or other forms of non-monetary relief
will remain available under Delaware law. In addition, each director will
continue to be subject to liability for breach of the director's duty of
loyalty to the Registrant, for acts or omissions not in good faith or
involving intentional misconduct, for knowing violations of law and for any
transaction from which the director derived an improper personal benefit. The
provision does not affect a director's responsibilities under any other laws,
such as the federal securities laws or state or federal environmental laws.
 
  In addition, each of the Registrant's directors and executive officers will
be indemnified by the Registrant, to the fullest extent permitted by the
Delaware Law and the Registrant's Bylaws, pursuant to indemnification
agreements with the Registrant.
 
  The Underwriting Agreement filed as Exhibit 1.1 to this Registration
Statement provides for indemnification by the Underwriters of the Registrant
and its officers and directors in the offering for certain liabilities arising
under the Securities Act or otherwise.
 
ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES.
 
  Since January 1, 1994, the Company has issued and/or sold unregistered
securities as set forth below.
 
    (1) During the period, the Registrant granted stock options to employees,
  consultants, directors, officers and affiliates of the Registrant as
  provided below. From May 9, 1996 to February 28, 1997, the
 
                                     II-1
<PAGE>
 
  Registrant granted stock options under the 1996 Stock Option and Grant Plan
  covering an aggregate of 1,338,807 shares of Common Stock at a weighted
  average exercise price of $2.42 per share. Unless canceled in accordance
  with its terms, each of these options vests over a period of time following
  its date of grant.
 
    (2) On March 14, 1996, the Company sold 26,000 shares of its Series A
  Convertible Participating Preferred Stock to a group of investors for an
  aggregate purchase price of $26.0 million.
 
    (3) On March 14, 1996, the Company effected a recapitalization. Pursuant
  to that recapitalization, the Company issued an aggregate of 6,500 shares
  of its Series B Convertible Participating Preferred Stock to Guy M. Lammle,
  the Company's Chief Executive Officer, President and Chairman of the Board,
  Rita L. Lammle, Amy Lammle Trust, Daina Lammle Trust and Lacey Lammle Trust
  (the "Lammles") in partial consideration for 60% of the Lammles' previous
  holdings of the Company's capital stock.
 
    (4) On March 14, 1996, the Company sold 1,473,943 shares of the Company's
  Common Stock (the "Lammle Shares") to Guy M. Lammle at a purchase price per
  share of $0.217 under the Company's 1996 Stock Option and Grant Plan. The
  Company has a repurchase option, which terminates entirely on March 31,
  2006 (subject to earlier termination for the Company's achievement of
  certain performance targets and the redemption of the Company's redeemable
  preferred stock), with respect to the Lammle Shares. Subject to adjustment
  for the Company's achievement of certain performance targets and the
  redemption of the Company's redeemable preferred stock, the Company's
  repurchase option with respect to the Lammle Shares will lapse at a rate of
  131,602 shares per quarter through March 31, 1998, and thereafter at a rate
  of 13,160 shares per quarter through March 31, 2006. Upon redemption of the
  Company's redeemable preferred stock in connection with this offering,

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

shall be as provided in this Article IV.

     A.   SERIES A CONVERTIBLE PREFERRED STOCK
          
          1.   ELECTION OF DIRECTORS:  VOTING.

               a.   ELECTION OF DIRECTORS. The holders of outstanding shares of
Series A Convertible Preferred Stock shall, voting separately as a separate
class, be entitled to elect two (2) Directors (the "Director Designees"), with
votes cast against such candidates and votes withheld having no legal effect.
The election of the Director Designees by the holders of the Series A
Convertible Preferred Stock shall occur (i) at the annual meeting of holders of
capital stock, (ii) at any special meeting of holders of capital stock, (iii) at
any special meeting of holders of Series A Convertible Preferred Stock called by
holders of two-thirds of the outstanding shares of Series A Convertible
Preferred Stock, or (iv) by the unanimous written consent of holders of the
outstanding shares of Series A Convertible Preferred Stock. If at any time when
any share of Series A Convertible Preferred Stock is outstanding a Director
Designee should cease to be a Director for any reason, the vacancy shall only be
filled by the vote or written consent of the holders of the outstanding shares
of Series A Convertible Preferred Stock, voting separately as a separate class,
in the manner and on the basis specified above. The holders of outstanding
shares of Series A Convertible Preferred Stock shall also be entitled to vote
for all other Directors of the Corporation together with holders of all other
shares of the Corporation's outstanding capital stock entitled to vote thereon,
voting together as a single class, with each outstanding share entitled to the
same number of votes specified in Section A.1(b). The holders of outstanding
shares of Series A Convertible Preferred Stock may, in their sole discretion,
determine to elect less than two Director Designees from time to time, and
during any such period the Board of Directors nonetheless shall be deemed duly
constituted.

               b.   VOTING GENERALLY.  The holder of each share of Series A
Convertible Preferred Stock shall be entitled to notice of any stockholders'
meeting in accordance with the by-laws of the Corporation and shall vote with
holders of Series B Convertible Preferred Stock and holders of the Common Stock,
voting together as single class, upon all matters submitted to a vote of
stockholders.  The holder of each share of Series A Convertible Preferred Stock
shall be entitled to the number of votes equal to the largest number of full
shares of Common Stock into which each share of Series A Convertible Preferred
Stock could be converted pursuant to Section A.4 hereof on the record date for
the vote or for written consent of stockholders, if applicable.  In addition,
the holders of the Series A Convertible Preferred Stock shall also be entitled
to vote separately as a class with respect to those matters required to be
submitted to a class or series vote pursuant to the terms hereof (including,
without limitation, Section A.7) or by law.  Fractional votes shall not,
however, be permitted and any fractional voting rights resulting from the above
formula (after aggregating all shares of Common Stock into which shares of
Series A Convertible Preferred Stock held by each holder could be converted)
shall be rounded to the nearest whole number (with one-half rounded upward to
one).

                                       2
<PAGE>
 
          2.   DIVIDENDS.  In the event the Board of Directors of the
Corporation shall declare a dividend payable upon outstanding shares of the
Common Stock, the holders of the Series A Convertible Preferred Stock shall be
entitled to the same amount of dividends per share of the Series A Convertible
Preferred Stock as such holders would have been entitled had such holders'
shares of Series A Convertible Preferred Stock been fully converted into shares
of Common Stock pursuant to the provisions of Section A.4 hereof as of the
record date for the determination of holders of shares of the Common Stock
entitled to receive such dividend.

          3.   LIQUIDATION AND OTHER EXTRAORDINARY TRANSACTIONS.

               a.   LIQUIDATION PREFERENCE.  Upon (i) any liquidation,
dissolution or winding up of the Corporation and its subsidiaries, whether
voluntary or involuntary (a "Liquidation Event"), or (ii) (w) a merger or
consolidation of the Corporation with or into another corporation (with respect
to which less than a majority of the outstanding voting power of such surviving
corporation is held by stockholders of the Corporation immediately prior to such
event), (x) the sale or transfer of all or substantially all of the properties
and assets of the Corporation and its subsidiaries, (y) any purchase by any
party (other than one of the Investors (as such term is defined in that certain
Stockholders' Agreement dated as of March 14, 1996 among the Corporation and
certain stockholders of the Corporation)) of shares of capital stock of the
Corporation (either through a negotiated stock purchase or a tender for such
shares), the effect of which is that such party that did not beneficially own a
majority of the voting power of the outstanding shares of capital stock of the
Corporation immediately prior to such purchase beneficially owns at least a
majority of such voting power immediately after such purchase, or (z) the
redemption or repurchase of shares representing a majority of the voting power
of the outstanding shares of capital stock of the Corporation (each an
"Extraordinary Transaction"), each holder of outstanding shares of Series A
Convertible Preferred Stock shall be entitled to be paid out of the assets of
the Corporation available for distribution to stockholders, whether such assets
are capital, surplus or earnings:

                    (i) on a parity with the payment of the Senior Series B
Convertible Liquidation Amount (as defined in Section B.3) due on any
outstanding Series B Convertible Preferred Stock and the Senior Redeemable
Liquidation Amount (as defined in Section C.3) due on any outstanding Senior
Redeemable Preferred Stock, and before any amount shall be paid or distributed
to the holders of Common Stock or of any other stock ranking on liquidation
junior to the Series A Convertible Preferred Stock (including, without
limitation, the Junior Redeemable Preferred Stock), an amount in cash equal to
$596.15384 per share (adjusted appropriately for stock splits, stock dividends,
recapitalizations and the like with respect to the Series A Convertible
Preferred Stock) (the "Senior Series A Convertible Liquidation Amount");
provided, however, that if, upon any Liquidation Event or Extraordinary
Transaction, the amounts payable with respect to the Senior Series A Convertible
Liquidation Amount, the Senior Series B Convertible Liquidation Amount and the
Senior Redeemable Liquidation Amount are not paid in full, the holders of the
Series A Convertible Preferred Stock, the Series B Convertible Preferred Stock
and the Senior Redeemable Preferred Stock, if any, shall share ratably in any
distribution of assets in proportion to such respective preferential amounts;
and

                                       3
<PAGE>
 
                    (ii) after the payment of the Senior Series A Convertible
Liquidation Amount, the Senior Series B Convertible Liquidation Amount and the
Senior Redeemable Liquidation Amount, and (except for payments contemplated by
clause (B) below which shall be made on a parity with payments to the holders
of Common Stock) before any amount shall be paid or distributed to the holders
of Common Stock or of any other stock ranking on liquidation junior to the
Series A Convertible Preferred Stock (including, without limitation, the Junior
Redeemable Preferred Stock or with respect to the Series B Convertible Preferred
Stock, the Junior Series B Convertible Liquidation Amount and the Residual
Series B Convertible Liquidation Amount (as such terms are defined in Section
B.3)), an amount equal to the greater of: (A) $403.84616 per share (adjusted
appropriately for stock splits, stock dividends, recapitalizations and the like
with respect to the Series A Convertible Preferred Stock); or (B) the amount
such holder would have received as a result of such Liquidation Event or
Extraordinary Transaction after the Senior Series A Convertible Liquidation
Amount shall have been paid in full, the Senior Series B Convertible Liquidation
Amount and the Junior Series B Convertible Liquidation Amount shall have been
paid in full, the Senior Redeemable Liquidation Amount, if any, shall have been
paid in full and the Junior Redeemable Liquidation Amount (as defined in Section
D.3) shall have been paid in full to the holders of the Junior Redeemable
Preferred Stock and any assets remaining available for distribution shall be
distributed ratably among the holders of the Common Stock, the Series A
Convertible Preferred Stock and the Series B Convertible Preferred Stock based
upon the number of shares of Common Stock (i) then held by each holder of Common
Stock, (ii) issuable upon conversion of the shares of Series A Convertible
Preferred Stock held by a holder of Series A Convertible Preferred Stock
pursuant to Section A.4 immediately prior to the occurrence of any such
Liquidation Event or Extraordinary Transaction or (iii) issuable upon conversion
of the shares of Series B Convertible Preferred Stock held by a holder of Series
B Convertible Preferred Stock pursuant to Section B.4 immediately prior to the
occurrence of any such Liquidation Event or Extraordinary Transaction (the
"Residual Series A Convertible Liquidation Amount" and, together with the Senior
Series A Convertible Liquidation Amount, the "Total Series A Convertible
Liquidation Amount"); provided, however, that if, upon any Liquidation Event or
Extraordinary Transaction, the Residual Series A Convertible Liquidation Amount
is not paid in full, the holders of the Series A Convertible Preferred Stock
shall share ratably in any distribution of assets in proportion to the full
respective preferential amounts to which they are entitled. Upon payment in full
of the Total Series A Convertible Liquidation Amount in accordance with the
terms hereof, the holders of the Series A Convertible Preferred Stock shall not
have any conversion rights hereunder.

               b.   CONVERSION RIGHTS NOT IMPAIRED. Except to the extent that
the holders of Series A Convertible Preferred Stock shall have been paid in full
under Section A.3(a), nothing in this Section A.3 shall in any way limit the
right of conversion of the holders of the Series A Convertible Preferred Stock
under Section A.4.

               c.   NON-CASH CONSIDERATION. Notwithstanding the provisions of
Section A.3(a), in connection with any Extraordinary Transaction, the holders of
Series A Convertible Preferred Stock shall, on the effective date of such
Extraordinary Transaction, be paid by the Corporation, in cash solely to the
extent that cash is paid in such Extraordinary Transaction and then (or
alternatively if no cash payments are involved, as applicable) in such

                                       4
<PAGE>
 
other consideration (valued as provided below) as is delivered in such
Extraordinary Transaction in an amount equal to the Total Series A Convertible
Liquidation Amount.

     Any securities or other consideration to be delivered to the holders
of the Series A Convertible Preferred Stock upon any Extraordinary Transaction
shall be valued as follows:  (i) if traded on a nationally recognized securities
exchange or inter-dealer quotation system, the value shall be deemed to be the
average of the closing prices of the securities on such exchange or system over
the 30-day period ending three (3) business days prior to the closing; (ii) if
traded over-the-counter, the value shall be deemed to be the average of the
closing bid prices over the 30-day period ending three (3) business days prior
to the closing; and (iii) if there is no active public market, the value shall
be the fair market value thereof, as mutually determined by the Corporation and
the holders of not less than a majority in voting power of the outstanding
shares of Series A Convertible Preferred Stock and Series B Convertible
Preferred Stock (voting together as a single class on an as-converted basis),
provided that if the Corporation and the holders of a majority in voting power
of the outstanding shares of Series A Convertible Preferred Stock and Series B
Convertible Preferred Stock (voting together as a single class on an as-
converted basis) are unable to reach agreement, then by independent appraisal by
an investment banker hired and paid by the Corporation, but reasonably
acceptable to the holders of a majority in voting power of the outstanding
shares of Series A Convertible Preferred Stock and Series B Convertible
Preferred Stock (voting together as a single class on an as-converted basis).

               d.   SURRENDER OF CERTIFICATES. On the effective date of any
Extraordinary Transaction, the Corporation shall pay all cash and other
consideration to which the holders of Series A Convertible Preferred Stock shall
be entitled under this Section A.3. Upon receipt of such payment, each holder of
shares of Series A Convertible Preferred Stock shall surrender the certificate
or certificates representing such shares, duly assigned or endorsed for transfer
to the Corporation (or accompanied by duly executed stock powers relating
thereto), at the principal executive office of the Corporation or the offices of
the transfer agent for the Series A Convertible Preferred Stock, or shall notify
the Corporation or any transfer agent that such certificates have been lost,
stolen or destroyed and shall execute an affidavit or agreement satisfactory to
the Corporation to indemnify the Corporation from any loss incurred by it in
connection therewith (an "Affidavit of Loss"), and each surrendered certificate
shall be canceled and retired.

               e.   NOTICE.  Prior to the occurrence of any Liquidation Event or
Extraordinary Transaction, the Corporation will furnish each holder of Series A
Convertible Preferred Stock notice in accordance with Section A.8 hereof,
together with a certificate prepared by the chief financial officer of the
Corporation describing in detail the facts of such Liquidation Event or
Extraordinary Transaction, stating in reasonable detail the amount(s) per share
of Series A Convertible Preferred Stock each holder of Series A Convertible
Preferred Stock would receive pursuant to the provisions of Section A.3(a)
hereof and stating in reasonable detail the facts upon which such amount was
determined and, in connection with any Extraordinary Transaction, describing in
reasonable detail all material terms of such Extraordinary Transaction,
including without limitation the consideration to be delivered in connection
with such 

                                       5
<PAGE>
 
Extraordinary Transaction, the valuation of the Corporation at the time of such
Extraordinary Transaction and the identities of the parties to the Extraordinary
Transaction.

          4.   CONVERSION. The holders of the Series A Convertible Preferred
Stock shall have the following conversion rights:

               a.   VOLUNTARY CONVERSION. At any time, each holder of shares of
Series A Convertible Preferred Stock shall be entitled, without the payment of
any additional consideration, to cause each outstanding share of Series A
Convertible Preferred Stock held by such holder to be converted into (i) the
number of fully paid and nonassessable shares of Common Stock which results from
dividing the Series A Conversion Price (as defined in this Section A.4(a)) then
in effect at the time of conversion into the Conversion Value of the Series A
Convertible Preferred Stock, which shall initially be $1.000 per share, and (ii)
 .59615384 of a fully paid and nonassessable share of Senior Redeemable Preferred
Stock. The "Series A Conversion Price" shall be $10.00 per share of Common
Stock, subject to adjustment from time to time as provided in Section A.5
hereof. If a holder of shares of Series A Convertible Preferred Stock elects to
convert the outstanding shares of Series A Convertible Preferred Stock at a time
when there are any declared but unpaid dividends or other amounts due on or in
respect of such shares, such dividends and other amounts shall be paid in full
in cash by the Corporation in connection with such conversion. If a holder of
Series A Convertible Preferred Stock elects to convert under this Section
A.4(a), such holder shall deliver to the Corporation a written notice of
conversion specifying (i) the number of shares of Series A Convertible Preferred
Stock to be converted, (ii) the name or names in which such holder wishes the
certificate or certificates for Common Stock and Senior Redeemable Preferred
Stock and for any Series A Convertible Preferred Stock not to be so converted to
be issued and (iii) the address to which such holder wishes delivery to be made
of such new certificates to be issued upon such conversion.

               b.   AUTOMATIC CONVERSION. Each share of Series A Convertible
Preferred Stock shall automatically be converted, without the payment of any
additional consideration, into shares of Common Stock and Senior Redeemable
Preferred Stock on the basis provided in Section A.4(a) above upon (i) the
written election of the holder or holders of not less than two-thirds in voting
power of the outstanding shares of Series A Convertible Preferred Stock or (ii)
the closing of an underwritten public offering pursuant to an effective
registration statement under the Securities Act of 1933, as amended, covering
the offer and sale of Common Stock of the Corporation to the public at an
initial public offering price of not less than $20.00 per share (subject to
adjustment for stock splits, stock dividends, recapitalizations and the like)
and resulting in proceeds received by the Corporation, net of underwriting
discounts and commissions, of at least $30,000,000 (a "Qualified Public
Offering"); provided that, in connection with any conversion resulting from a
Qualified Public Offering, each holder of Series A Convertible Preferred Stock
shall receive in lieu of shares of Senior Redeemable Preferred Stock and
notwithstanding anything herein to the contrary, payment in full of the
redemption price for each share of Senior Redeemable Preferred Stock to which
such holder is entitled under Section C.4.

               c.   CONVERSION PROCEDURES. Any holder of Series A Convertible
Preferred Stock converting such shares into shares of Common Stock and Senior
Redeemable

                                       6
<PAGE>
 
Preferred Stock, or whose shares are automatically converted pursuant to Section
A.4(b), shall surrender the certificate or certificates representing the Series
A Convertible Preferred Stock being converted, duly assigned or endorsed for
transfer to the Corporation (or accompanied by duly executed stock powers
relating thereto), at the principal executive office of the Corporation or the
offices of the transfer agent for the Series A Convertible Preferred Stock or
such office or offices in the continental United States of an agent for
conversion as may from time to time be designated by notice to the holders of
the Series A Convertible Preferred Stock by the Corporation, or shall deliver an
Affidavit of Loss with respect to such certificates. Upon surrender of a
certificate representing Series A Convertible Preferred Stock for conversion,
the Corporation shall issue and send by hand delivery, by courier or by first
class mail (postage prepaid) to the holder thereof or to such holder's designee,
at the address designated by such holder, a certificate or certificates for the
number of shares of Common Stock and Senior Redeemable Preferred Stock to which
such holder shall be entitled upon conversion. In the event that there shall
have been surrendered a certificate or certificates representing Series A
Convertible Preferred Stock, only part of which are to be converted, the
Corporation shall issue and send to such holder or such holder's designee, in
the manner set forth in the preceding sentence, a new certificate or
certificates representing the number of shares of Series A Convertible Preferred
Stock which shall not have been converted. The issuance of certificates for
Common Stock and Senior Redeemable Preferred Stock upon conversion of Series A
Convertible Preferred Stock will be made without charge to the holders of such
shares for any issuance tax in respect thereof or other costs incurred by the
Corporation in connection with such conversion and the related issuance of such
stock. Notwithstanding anything to the contrary set forth in this Section
A.4(c), in the event that the holders of shares of Series A Convertible
Preferred Stock elect to convert such shares in connection with any Liquidation
Event or Extraordinary Transaction, the holders shall deliver notice of such
conversion no later than five (5) days before the occurrence of such Liquidation
Event or the closing of such Extraordinary Transaction and such notice shall be
effective as of, and shall in all cases be subject to, the occurrence of such
Liquidation Event or closing of such Extraordinary Transaction. If such
Liquidation Event or Extraordinary Transaction occurs, all outstanding shares of
Series A Convertible Preferred Stock elected to be converted shall be deemed to
have been converted into shares of Common Stock and Senior Redeemable Preferred
Stock immediately prior thereto, and the Corporation shall make appropriate
provisions (i) for the Common Stock issued upon such conversion to be treated on
the same basis as all other Common Stock in such Liquidation Event or
Extraordinary Transaction and (ii) for the payment of the Senior Redeemable
Liquidation Amount in connection with any Liquidation Event or the redemption of
the Senior Redeemable Preferred Stock (issued upon such conversion) upon
election of such redemption in connection with any Extraordinary Transaction, if
applicable, as provided herein.

               d.   EFFECTIVE DATE OF CONVERSION. The issuance by the
Corporation of shares of Common Stock and Senior Redeemable Preferred Stock upon
a conversion of Series A Convertible Preferred Stock into shares of Common Stock
and Senior Redeemable Preferred Stock at the option of the holder(s) thereof
pursuant to Section A.4(a) or A.4(b) hereof shall be effective as of the
surrender of the certificate or certificates for the Series A Convertible
Preferred Stock to be converted, duly assigned or endorsed for transfer to the
Corporation (or

                                       7
<PAGE>
 
accompanied by duly executed stock powers relating thereto) or delivery of an
Affidavit of Loss with respect to such certificates. The issuance by the
Corporation of shares of Common Stock and Senior Redeemable Preferred Stock upon
a conversion of Series A Convertible Preferred Stock into Common Stock and
Senior Redeemable Preferred Stock pursuant to Section A.4(b) hereof upon a
Qualified Public Offering shall be deemed to be effective immediately prior to
the closing of the Qualified Public Offering. On and after the effective date of
conversion, the person or persons entitled to receive the Common Stock and
Senior Redeemable Preferred Stock issuable upon such conversion shall be treated
for all purposes as the record holder or holders of such shares of Common Stock
and Senior Redeemable Preferred Stock.

               e.   NO IMPAIRMENT. The Corporation shall not, by amendment of
this Amended and Restated Certificate of Incorporation or through any
Extraordinary Transaction or other reorganization, transfer of assets,
consolidation, merger, dissolution, issue or sale of securities or any other
voluntary action, avoid or seek to avoid the observance or performance of any of
the terms to be observed or performed hereunder by the Corporation but shall at
all times in good faith assist in the carrying out of all the provisions of this
Section A.4 and in the taking of all such action as may be necessary or
appropriate in order to protect the conversion and other rights of the holders
of the Series A Convertible Preferred Stock and the Senior Redeemable Preferred
Stock against impairment.

               f.   RESERVATION OF STOCK ISSUABLE UPON CONVERSION. The
Corporation shall at all times reserve and keep available out of its authorized
but unissued shares of Common Stock and Senior Redeemable Preferred Stock solely
for the purpose of effecting the conversion of the shares of Series A
Convertible Preferred Stock such number of its shares of Common Stock and Senior
Redeemable Preferred Stock as shall from time to time be sufficient to effect
the conversion of all outstanding shares of Series A Convertible Preferred
Stock; and if at any time the number of authorized but unissued shares of Common
Stock and Senior Redeemable Preferred Stock shall not be sufficient to effect
the conversion of all then outstanding shares of Series A Convertible Preferred
Stock, the Corporation will take such corporate action as may be necessary to
increase its authorized but unissued shares of Common Stock and Senior
Redeemable Preferred Stock to such number of shares as shall be sufficient for
such purpose.

               g.   NO CLOSING OF TRANSFER BOOKS. The Corporation shall not
close its books against the transfer of shares of Series A Convertible Preferred
Stock in any manner which would interfere with the timely conversion of any
shares of Series A Convertible Preferred Stock.

          5.   ADJUSTMENTS.

               a.   If the number of shares of Common Stock outstanding at any
time after the date hereof is increased by a stock dividend payable in shares of
Common Stock or by a subdivision or split-up of shares of Common Stock, then, on
the date such payment is made or such change is effective, the Series A
Conversion Price shall be appropriately decreased so that the number of shares
of Common Stock issuable on conversion of any shares of Series A

                                       8
<PAGE>
 
Convertible Preferred Stock shall be increased in proportion to such increase of
outstanding shares of Common Stock.

               b.   If the number of shares of Common Stock outstanding at any
time after the date hereof is decreased by a combination or reverse split of the
outstanding shares of Common Stock, then, on the effective date of such
combination or reverse split, the Series A Conversion Price of the Series A
Convertible Preferred Stock shall be appropriately increased so that the number
of shares of Common Stock issuable on conversion of any shares of Series A
Convertible Preferred Stock shall be decreased in proportion to such decrease in
outstanding shares of Common Stock.

               c.   In case, at any time after the date hereof, of any capital
reorganization (other than a reorganization constituting an Extraordinary
Transaction), or any reclassification of the stock of the Corporation (other
than as a result of a stock dividend payable on shares of Common Stock in the
form of Common Stock or subdivision, split-up or combination involving the
Common Stock), the shares of Series A Convertible Preferred Stock shall, after
such capital reorganization or reclassification, be convertible into the kind
and number of shares of stock or other securities or property of the Corporation
or otherwise to which such holder would have been entitled if immediately prior
to such capital reorganization or reclassification he or it had converted his or
its shares of Series A Convertible Preferred Stock into Common Stock and Senior
Redeemable Preferred Stock. The provisions of this clause (c) shall similarly
apply to successive capital reorganizations or reclassifications.

               d.   All calculations under this Section A.5 shall be made to the
nearest cent or to the nearest one hundredth (1/100) of a share, as the case may
be.

               e.   Upon the occurrence of each adjustment or readjustment
pursuant to this Section A.5, the Corporation at its expense shall promptly
compute such adjustment or readjustment in accordance with the terms hereof and
prepare and furnish to each holder of Series A Convertible Preferred Stock a
certificate setting forth such adjustment or readjustment and showing in detail
the facts upon which such adjustment or readjustment is based. The Corporation
shall, upon written request at any time of any holder of Series A Convertible
Preferred Stock, furnish or cause to be furnished to such holder a like
certificate setting forth (i) such adjustments and readjustments, (ii) the
Series A Conversion Price before and after such adjustment or readjustment, and
(iii) the number of shares of Common Stock and Senior Redeemable Preferred Stock
and the amount, if any, of other property which at the time would be received
upon the conversion of such holder's shares of Series A Convertible Preferred
Stock.

          6.   REDEMPTION.

               a.   MANDATORY REDEMPTION. Upon the election of the holder or
holders of two-thirds in voting power of the outstanding Series A Convertible
Preferred Stock and Series B Convertible Preferred Stock (voting together as a
single class on an as-converted basis) made at any time on or before March 1,
2001, the Corporation shall, to the extent it may do so under applicable law,
redeem all of the outstanding shares of Series A Convertible Preferred Stock
pursuant to this Section A.6 in three equal installments on March 31, 2001,

                                       9
<PAGE>
 
March 31, 2002 and March 31, 2003 (each, a "Redemption Date") and the Series B
Convertible Preferred Stock pursuant to Section B.6.  The foregoing election
shall be made by such holders giving written notice on or before March 1, 2001
to the Corporation and each of the other holders of Series A Convertible
Preferred Stock.

               b.   REDEMPTION PRICE. Upon the election to cause the Corporation
to redeem the Series A Convertible Preferred Stock pursuant to Section A.6(a),
all holders of Series A Convertible Preferred Stock shall be deemed to have
elected to cause the Series A Convertible Preferred Stock to be so redeemed. The
redemption price for each share of Series A Convertible Preferred Stock redeemed
pursuant to this Section A.6 shall be the sum of (x) the Total Series A
Convertible Liquidation Amount, plus (y) any unpaid dividends to which such
holder of outstanding shares of Series A Convertible Preferred Stock is entitled
under Section A.2 and Section A.6(d) hereof (the "Series A Convertible Preferred
Redemption Price"); provided, however, that if at a Redemption Date shares of
Series A Convertible Preferred Stock are unable to be redeemed (as contemplated
by Section A.6(c) below), in addition to the Series A Convertible Preferred
Redemption Price the holders of Series A Convertible Preferred Stock shall be
entitled to any interest accrued pursuant to Section A.6(c). The Series A
Convertible Preferred Redemption Price shall be payable in cash in immediately
available funds on the Redemption Date. Until the full Series A Convertible
Preferred Redemption Price, including any interest thereon, has been paid in
cash for all shares of Series A Convertible Preferred Stock redeemed as of the
applicable Redemption Date: (A) no dividend whatsoever shall be paid or
declared, and no distribution shall be made, on any capital stock of the
Corporation (other than the dividends accruing on the Senior Redeemable
Preferred Stock); and (B) no shares of capital stock of the Corporation (other
than the Series A Convertible Preferred Stock in accordance with this Section
A.6 and, with respect to the Senior Series B Convertible Liquidation Amount, the
Series B Convertible Preferred Stock in accordance with Section B.6) shall be
purchased, redeemed or acquired by the Corporation and no monies shall be paid
into or set aside or made available for a sinking fund for the purchase,
redemption or acquisition thereof, other than pursuant to vesting, first refusal
or repurchase provisions of agreements with employees, officers, directors or
consultants of the Corporation in which the Corporation repurchases shares of
capital stock of the Corporation at the original purchase price paid therefor by
the applicable individual.

               c.   INSUFFICIENT FUNDS FOR REDEMPTION. If, at a Redemption Date,
the Corporation is prohibited under the General Corporation Law of the State of
Delaware from redeeming all shares of Series A Convertible Preferred Stock for
which redemption is required hereunder, then it shall redeem such shares on a
pro-rata basis among the holders of Series A Convertible Preferred Stock and the
Series B Convertible Preferred Stock (and, if applicable, the Senior Redeemable
Preferred Stock) in proportion to the full respective redemption amounts to
which they are entitled hereunder to the extent possible and shall redeem the
remaining shares to be redeemed as soon as the Corporation is not prohibited
from redeeming some or all of such shares under the General Corporation Law of
the State of Delaware. The shares of Series A Convertible Preferred Stock not
redeemed shall remain outstanding and entitled to all of the rights and
preferences provided in this Article IV. In the event that the Corporation fails
for any reason to redeem shares for which redemption is required pursuant to
Section A.6, then during the period from the applicable Redemption Date through
the date on which such unredeemed shares are redeemed, the applicable Series A
Convertible Preferred Redemption Price of such shares

                                       10
<PAGE>
 
shall bear interest at the greater of twelve percent (12%) per annum or five
percent (5%) over the then prevailing prime rate, which interest shall be
compounded annually.

               d.   DIVIDEND AFTER REDEMPTION DATE. From and after a Redemption
Date, no shares of Series A Convertible Preferred Stock subject to redemption
shall be entitled to any further dividends pursuant to Section A.2 hereof;
provided, however, that in the event that shares of Series A Convertible
Preferred Stock are unable to be redeemed and continue to be outstanding in
accordance with Section A.6(c), such shares shall continue to be entitled to
dividends and interest thereon as provided in Sections A.6(b) and A.6(c) until
the date on which such shares are actually redeemed by the Corporation.

               e.   SURRENDER OF CERTIFICATES. Upon receipt of the applicable
Series A Convertible Preferred Redemption Price by certified check or wire
transfer, each holder of shares of Series A Convertible Preferred Stock to be
redeemed shall surrender the certificate or certificates representing such
shares to the Corporation, duly assigned or endorsed for transfer (or
accompanied by duly executed stock powers relating thereto), or shall deliver an
Affidavit of Loss with respect to such certificates at the principal executive
office of the Corporation or the office of the transfer agent for the Series A
Convertible Preferred Stock or such office or offices in the continental United
States of an agent for redemption as may from time to time be designated by
notice to the holders of Series A Convertible Preferred Stock, and each
surrendered certificate shall be canceled and retired.

          7.   COVENANTS.  So long as any shares of Series A Convertible
Preferred Stock shall be outstanding, the Corporation shall not, without first
having provided the written notice of such proposed action to each holder of
outstanding shares of Series A Convertible Preferred Stock and having obtained
the affirmative vote or written consent of the holders of a majority in voting
power of the outstanding shares of Series A Convertible Preferred Stock, voting

          8.   NOTICE.
          
               a.   LIQUIDATION EVENTS, EXTRAORDINARY TRANSACTIONS, ETC. In the
event (i) the Corporation establishes a record date to determine the holders of
any class of securities who are entitled to receive any dividend or other
distribution or who are entitled to vote at a meeting (or by written consent) in
connection with any of the transactions identified in clause (ii) hereof, or
(ii) any Liquidation Event (as defined in Section A.3), any Extraordinary

issuable upon conversion of the shares of Series B Convertible Preferred Stock
held by a holder of Series B Convertible Preferred Stock pursuant to Section B.4

Extraordinary Transaction (the "Residual Series B Convertible Liquidation
Amount" and, together with the Senior Series B Convertible Liquidation Amount
and the Junior Series B Convertible Liquidation Amount, (the "Total Series B

Liquidation Event or Extraordinary Transaction, the Residual Series B
Convertible Liquidation Amount is not paid in full, the holders of the Series B

proportion to the full respective preferential amounts to which they are
entitled. Upon payment in full of the Total Series B Convertible Liquidation
Amount in accordance with the terms hereof, the holders of the Series B

               b.   CONVERSION RIGHTS NOT IMPAIRED. Except to the extent that
the holders of Series B Convertible Preferred Stock shall have been paid in full

               c.   NON-CASH CONSIDERATION. Notwithstanding the provisions of
Section B.3(a), in connection with any Extraordinary Transaction, the holders of

extent that cash is paid in such Extraordinary Transaction and then (or
alternatively if no cash payments are involved, as applicable), in such other
consideration (valued as provided below) as is delivered in such Extraordinary
Transaction in an amount equal to the Total Series B Convertible Liquidation
Amount.

     Any securities or other consideration to be delivered to the holders of the
Series B Convertible Preferred Stock upon any Extraordinary Transaction shall be
valued pursuant to Section A.3(c) hereof.

               d.   SURRENDER OF CERTIFICATES. On the effective date of any
Extraordinary Transaction, the Corporation shall pay all cash and other
consideration to which the holders of Series B Convertible Preferred Stock shall
be entitled under this Section B.3. Upon receipt of such payment, each holder of
shares of Series B Convertible Preferred Stock shall surrender the certificate
or certificates representing such shares, duly assigned or endorsed for transfer
to the Corporation (or accompanied by duly executed stock powers relating
thereto), at the principal executive office of the Corporation or the offices of
the transfer agent for the Series B Convertible Preferred Stock, or shall notify

          4.   CONVERSION. The holders of the Series B Convertible Preferred
Stock shall have the following conversion rights:

               a.   VOLUNTARY CONVERSION. At any time, each holder of shares of
Series B Convertible Preferred Stock shall be entitled, without the payment of
any additional consideration, to cause each outstanding share of Series B
Convertible Preferred Stock held by such holder to be converted into (i) the
number of fully paid and nonassessable shares of Common Stock which results from
dividing the Series B Conversion Price (as defined in this Section B.4(a)) then
in effect at the time of conversion into the Conversion Value of the Series B
Convertible Preferred Stock, which shall initially be $1,000 per share, (ii)
 .59615384 of a fully paid and nonassessable share of Senior Redeemable Preferred
Stock and (iii) .40384616 of a fully paid and nonassessable share of Junior
Redeemable Preferred Stock. The "Series B Conversion Price" shall be $10.00 per
share of Common Stock, subject to adjustment from time to time as provided in
Section B.5 hereof. If a holder of shares of Series B Convertible Preferred
Stock elects to convert the outstanding shares of Series B Convertible Preferred
Stock at a time when there are any declared but unpaid dividends or other 
amounts due on or in respect of such shares, such dividends and other amounts
shall be paid in full in cash by the Corporation in connection with such
conversion. If a holder of Series B Convertible Preferred Stock elects to
convert under this Section B.4(a), such holder shall deliver to the Corporation
a written notice of conversion specifying (i) the number of shares of Series B
Convertible Preferred Stock to be converted, (ii) the name or names in which
such holder wishes the certificate or certificates for Common Stock, Senior
Redeemable Preferred Stock and Junior Redeemable Preferred Stock and for any
Series B Convertible Preferred Stock not to be so converted to be issued and
(iii) the address to which such holder wishes delivery to be made of such new
certificates to be issued upon such conversion.

               b.   AUTOMATIC CONVERSION. Each share of Series B Convertible
Preferred Stock shall automatically be converted, without the payment of any
additional consideration, into shares of Common Stock, Senior Redeemable
Preferred Stock and Junior Redeemable Preferred Stock on the basis provided in
Section B.4(a) above upon (i) the written election of the holder or holders of
not less than a majority in voting power of the outstanding shares of Series B
Convertible Preferred Stock, (ii) the written election of the holder or holders
of not less than two-thirds in voting power of the outstanding shares of Series
A Convertible Preferred Stock to convert such shares pursuant to Section A.4(b)
hereof, or (iii) the closing of a Qualified Public Offering; provided that, in
connection with any conversion resulting from a Qualified Public Offering, each
holder of Series B Convertible Preferred Stock shall receive in lieu of shares
of Senior Redeemable Preferred Stock and notwithstanding anything herein to the

                                       16
<PAGE>
 
contrary, payment in full of the redemption price for each share of Senior
Redeemable Preferred Stock to which such holder is entitled under Section C.4
and in lieu of shares of Junior Redeemable Preferred Stock and notwithstanding
anything herein to the contrary, payment in full of the redemption price for
each share of Junior Redeemable Preferred Stock to which such holder is entitled
under Section C.4.

               c.   CONVERSION PROCEDURES. Any holder of Series B Convertible
Preferred Stock converting such shares into shares of Common Stock, Senior
Redeemable Preferred Stock and Junior Redeemable Preferred Stock, or whose
shares are automatically converted pursuant to Section B.4(b), shall surrender
the certificate or certificates representing the Series B Convertible Preferred
Stock being converted, duly assigned or endorsed for transfer to the Corporation
(or accompanied by duly executed stock powers relating thereto), at the
principal executive office of the Corporation or the offices of the transfer
agent for the Series B Convertible Preferred Stock or such office or offices in
the continental United States of an agent for conversion as may from time to
time be designated by notice to the holders of the Series B Convertible
Preferred Stock by the Corporation, or shall deliver an Affidavit of Loss with
respect to such certificates. Upon surrender of a certificate representing
Series B Convertible Preferred Stock for conversion, the Corporation shall issue
and send by hand delivery, by courier or by first class mail (postage prepaid)
to the holder thereof or to such holder's designee, at the address designated by
such holder, a certificate or certificates for the number of shares of Common
Stock, Senior Redeemable Preferred Stock and Junior Redeemable Preferred Stock
to which such holder shall be entitled upon conversion. In the event that there
shall have been surrendered a certificate or certificates representing Series B
Convertible Preferred Stock, only part of which are to be converted, the
Corporation shall issue and send to such holder or such holder's designee, in
the manner set forth in the preceding sentence, a new certificate or
certificates representing the number of shares of Series B Convertible Preferred
Stock which shall not have been converted. The issuance of certificates for
Common Stock, Senior Redeemable Preferred Stock and Junior Redeemable Preferred
Stock upon conversion of Series B Convertible Preferred Stock will be made
without charge to the holders of such shares for any issuance tax in respect
thereof or other costs incurred by the Corporation in connection with such
conversion and the related issuance of such stock. Notwithstanding anything to
the contrary set forth in this Section B.4(c), in the event that the holders of
shares of Series B Convertible Preferred Stock elect to convert such shares in
connection with any Liquidation Event or Extraordinary Transaction, the holders
shall deliver notice of such conversion no later than five (5) days before the
occurrence of such Liquidation Event or the closing of such Extraordinary
Transaction and such notice shall be effective as of, and shall in all cases be
subject to, the occurrence of such Liquidation Event or closing of such
Extraordinary Transaction. If such Liquidation Event or Extraordinary
Transaction occurs, all outstanding shares of Series B Convertible Preferred
Stock elected to be converted shall be deemed to have been converted into shares
of Common Stock, Senior Redeemable Preferred Stock and Junior Redeemable
Preferred Stock immediately prior thereto, and the Corporation shall make
appropriate provisions (i) for the Common Stock issued upon such conversion to
be treated on the same basis as all other Common Stock in such Liquidation Event
or Extraordinary Transaction, (ii) for the payment of the Senior Redeemable
Liquidation Amount in connection with any Liquidation Event or the redemption of
the Senior Redeemable Preferred Stock (issued upon such conversion) upon
election of such redemption in

                                       17
<PAGE>
 
connection with any Extraordinary Transaction, if applicable, as provided
herein, and (iii) for the payment of the Junior Redeemable Liquidation Amount in
connection with any Liquidation Event or the redemption of the Junior Redeemable
Preferred Stock (issued upon such conversion) upon election of such redemption
in connection with any Extraordinary Transaction, if applicable, as provided
herein.

               d.   EFFECTIVE DATE OF CONVERSION. The issuance by the
Corporation of shares of Common Stock, Senior Redeemable Preferred Stock and
Junior Redeemable Preferred Stock upon a conversion of Series B Convertible
Preferred Stock into shares of Common Stock, Senior Redeemable Preferred Stock
and Junior Redeemable Preferred Stock at the option of the holder(s) thereof
pursuant to Section B.4(a) or B.4(b) hereof shall be effective as of the
surrender of the certificate or certificates for the Series B Convertible
Preferred Stock to be converted, duly assigned or endorsed for transfer to the
Corporation (or accompanied by duly executed stock powers relating thereto) or
delivery of an Affidavit of Loss with respect to such certificates. The issuance
by the Corporation of shares of Common Stock, Senior Redeemable Preferred Stock
and Junior Redeemable Preferred Stock upon a conversion of Series B Convertible
Preferred Stock into Common Stock, Senior Redeemable Preferred Stock and Junior
Redeemable Preferred Stock pursuant to Section B.4(b) hereof upon the written
election of the holder or holders of not less than two-thirds in voting power of
the outstanding shares of Series A Convertible Preferred Stock to convert such
shares pursuant to Section A.4(b) hereof shall be deemed to be effective as of
the effective time of the conversion of such shares of Series A Convertible
Preferred Stock. The issuance by the Corporation of shares of Common Stock,
Senior Redeemable Preferred Stock and Junior Redeemable Preferred Stock upon a
conversion of Series B Convertible Preferred Stock into Common Stock, Senior
Redeemable Preferred Stock and Junior Redeemable Preferred Stock pursuant to
Section B.4(b) hereof upon a Qualified Public Offering shall be deemed to be
effective immediately prior to the closing of the Qualified Public Offering. On
and after the effective date of conversion, the person or persons entitled to
receive the Common Stock, Senior Redeemable Preferred Stock and Junior
Redeemable Preferred Stock issuable upon such conversion shall be treated for
all purposes as the record holder or holders of such shares of Common Stock,
Senior Redeemable Preferred Stock and Junior Redeemable Preferred Stock.

               e.   NO IMPAIRMENT. The Corporation shall not, by amendment of
this Amended and Restated Certificate of Incorporation or through any
Extraordinary Transaction or other reorganization, transfer of assets,
consolidation, merger, dissolution, issue or sale of securities or any other
voluntary action, avoid or seek to avoid the observance or performance of any of
the terms to be observed or performed hereunder by the Corporation but shall at
all times in good faith assist in the carrying out of all the provisions of this
Section B.4 and in the taking of all such action as may be necessary or
appropriate in order to protect the conversion and other rights of the holders
of the Series B Convertible Preferred Stock, the Senior Redeemable Preferred
Stock and the Junior Redeemable Preferred Stock against impairment.

               f.   RESERVATION OF STOCK ISSUABLE UPON CONVERSION. The
Corporation shall at all times reserve and keep available out of its authorized
but unissued shares of Common Stock, Senior Redeemable Preferred Stock and
Junior Redeemable Preferred Stock solely for the purpose of effecting the
conversion of the shares of Series B Convertible Preferred

                                       18
<PAGE>
 
Stock such number of its shares of Common Stock, Senior Redeemable Preferred
Stock and Junior Redeemable Preferred Stock as shall from time to time be
sufficient to effect the conversion of all outstanding shares of Series B
Convertible Preferred Stock; and if at any time the number of authorized but
unissued shares of Common Stock, Senior Redeemable Preferred Stock and Junior
Redeemable Preferred Stock shall not be sufficient to effect the conversion of
all then outstanding shares of Series B Convertible Preferred Stock, the
Corporation will take such corporate action as may be necessary to increase its
authorized but unissued shares of Common Stock, Senior Redeemable Preferred
Stock and Junior Redeemable Preferred Stock to such number of shares as shall be
sufficient for such purpose.

               g.   NO CLOSING OF TRANSFER BOOKS. The Corporation shall not
close its books against the transfer of shares of Series B Convertible Preferred
Stock in any manner which would interfere with the timely conversion of any
shares of Series B Convertible Preferred Stock.

          5.   ADJUSTMENTS.

               a.   If the number of shares of Common Stock outstanding at any
time after the date hereof is increased by a stock dividend payable in shares of
Common Stock or by a subdivision or split-up of shares of Common Stock, then, on
the date such payment is made or such change is effective, the Series B
Conversion Price shall be appropriately decreased so that the number of shares
of Common Stock issuable on conversion of any shares of Series B Convertible
Preferred Stock shall be increased in proportion to such increase of outstanding
shares of Common Stock.

               b.   If the number of shares of Common Stock outstanding at any
time after the date hereof is decreased by a combination or reverse split of the
outstanding shares of Common Stock, then, on the effective date of such
combination or reverse split, the Series B Conversion Price of the Series B
Convertible Preferred Stock shall be appropriately increased so that the number
of shares of Common Stock issuable on conversion of any shares of Series B
Convertible Preferred Stock shall be decreased in proportion to such decrease in
outstanding shares of Common Stock.

               c.   In case, at any time after the date hereof, of any capital
reorganization (other than a reorganization constituting an Extraordinary
Transaction), or any reclassification of the stock of the Corporation (other
than as a result of a stock dividend payable on shares of Common Stock in the
form of Common Stock or subdivision, split-up or combination involving the
Common Stock), the shares of Series B Convertible Preferred Stock shall, after
such capital reorganization or reclassification, be convertible into the kind
and number of shares of stock or other securities or property of the Corporation
or otherwise to which such holder would have been entitled if immediately prior
to such capital reorganization or reclassification he or it had converted his or
its shares of Series B Convertible Preferred Stock into Common Stock, Senior
Redeemable Preferred Stock and Junior Redeemable Preferred Stock. The provisions
of this clause (c) shall similarly apply to successive capital reorganizations
or reclassifications.

                                       19
<PAGE>
 
               d.   All calculations under this Section B.5 shall be made to the
nearest cent or to the nearest one hundredth (1/100) of a share, as the case may
be.

               e.   Upon the occurrence of each adjustment or readjustment
pursuant to this Section B.5, the Corporation at its expense shall promptly
compute such adjustment or readjustment in accordance with the terms hereof and
prepare and furnish to each holder of Series B Convertible Preferred Stock a
certificate setting forth such adjustment or readjustment and showing in detail
the facts upon which such adjustment or readjustment is based. The Corporation
shall, upon written request at any time of any holder of Series B Convertible
Preferred Stock, furnish or cause to be furnished to such holder a like
certificate setting forth (i) such adjustments and readjustments, (ii) the
Series B Conversion Price before and after such adjustment or readjustment, and
(iii) the number of shares of Common Stock, Senior Redeemable Preferred Stock
and Junior Redeemable Preferred Stock and the amount, if any, of other property
which at the time would be received upon the conversion of such holder's shares
of Series B Convertible Preferred Stock.

          6.   REDEMPTION.

               a.   MANDATORY REDEMPTION. Upon the election of the holder or
holders of two-thirds in voting power of the outstanding Series A Convertible
Preferred Stock and Series B Convertible Preferred Stock (voting together as a
single class on an as-converted basis) made at any time on or before March 1,
2001, the Corporation shall, to the extent it may do so under applicable law,
redeem all of the outstanding shares of Series B Convertible Preferred Stock
pursuant to this Section B.6 in three equal installments on March 31, 2001,
March 31, 2002 and March 31, 2003 (each, a "Redemption Date") and the Series A
Convertible Preferred Stock pursuant to Section A.6. The foregoing election
shall be made by such holders giving written notice on or before March 1, 2001
to the Corporation and each of the other holders of Series B Convertible
Preferred Stock.

               b.   REDEMPTION PRICE. Upon the election to cause the Corporation
to redeem the Series B Convertible Preferred Stock pursuant to Section B.6(a),
all holders of Series B Convertible Preferred Stock shall be deemed to have
elected to cause the Series B Convertible Preferred Stock to be so redeemed. The
redemption price for each share of Series B Convertible Preferred Stock redeemed
pursuant to this Section B.6 shall be the sum of (x) the Senior Series B
Convertible Liquidation Amount, plus (y) any unpaid dividends to which such
holder of outstanding shares of Series B Convertible Preferred Stock is entitled
under Section B.2 and Section B.6(d) hereof (the "Series B Convertible Preferred
Redemption Price"); provided, however, that if at a Redemption Date shares of
Series B Convertible Preferred Stock are unable to be redeemed (as contemplated
by Section B.6(c) below), in addition to the Series B Convertible Preferred
Redemption Price the holders of Series B Convertible Preferred Stock shall be
entitled to any interest accrued pursuant to Section B.6(c). The Series B
Convertible Preferred Redemption Price shall be payable in cash in immediately
available funds on the Redemption Date. In connection with any redemption of the
Series B Convertible Preferred Stock, the holders thereof shall also be entitled
to receive the Junior Redeemable Preferred Stock and Common Stock that would be
issuable upon conversion thereof. Until the full Series B Convertible Preferred
Redemption Price, including any interest thereon, has been paid in cash for

                                       20
<PAGE>
 
all shares of Series B Convertible Preferred Stock redeemed as of the applicable
Redemption Date: (A) no dividend whatsoever shall be paid or declared, and no
distribution shall be made, on any capital stock of the Corporation (other than
the dividends accruing on the Senior Redeemable Preferred Stock); and (B) no
shares of capital stock of the Corporation (other than the Series B Convertible
Preferred Stock in accordance with this Section B.6 and the Series A Convertible
Preferred Stock in accordance with Section A.6) shall be purchased, redeemed or
acquired by the Corporation and no monies shall be paid into or set aside or
made available for a sinking fund for the purchase, redemption or acquisition
thereof, other than pursuant to vesting, first refusal or repurchase provisions
of agreements with employees, officers, directors or consultants of the
Corporation in which the Corporation repurchases shares of capital stock of the
Corporation at the original purchase price paid therefor by the applicable
individual.

               c.   INSUFFICIENT FUNDS FOR REDEMPTION. If, at a Redemption Date,
the Corporation is prohibited under the General Corporation Law of the State of
Delaware from redeeming all shares of Series B Convertible Preferred Stock for
which redemption is required hereunder, then it shall redeem such shares on a
pro-rata basis among the holders of Series A Convertible Preferred Stock and the
Series B Convertible Preferred (and, if applicable, the Senior Redeemable
Preferred Stock) in proportion to the full respective redemption amounts to
which they are entitled hereunder to the extent possible and shall redeem the
remaining shares to be redeemed as soon as the Corporation is not prohibited
from redeeming some or all of such shares under the General Corporation Law of
the State of Delaware. The shares of Series B Convertible Preferred Stock not
redeemed shall remain outstanding and entitled to all of the rights and
preferences provided in this Article IV. In the event that the Corporation fails
for any reason to redeem shares for which redemption is required pursuant to
Section B.6, then during the period from the applicable Redemption Date through
the date on which such unredeemed shares are redeemed, the applicable Series B
Convertible Preferred Redemption Price of such shares shall bear interest at the
greater of twelve percent (12%) per annum or five percent (5%) over the then
prevailing prime rate, which interest shall be compounded annually.

               d.   DIVIDEND AFTER REDEMPTION DATE. From and after a Redemption
Date, no shares of Series B Convertible Preferred Stock subject to redemption
shall be entitled to any further dividends pursuant to Section B.2 hereof;
provided, however, that in the event that shares of Series B Convertible
Preferred Stock are unable to be redeemed and continue to be outstanding in

<PAGE>
 
Corporation to redeem such shares under Sections A.6 and B.6 hereof or to

Redeemable Preferred Stock (or two-thirds in voting power of Series A
Convertible Preferred Stock and the Series B Convertible Preferred Stock voting
together as a single class on an as-converted basis, as applicable, proposing to
convert in order to effect a redemption hereunder), the Corporation shall, to
the extent it may do so under applicable law, redeem all of the outstanding
shares of Senior Redeemable Preferred Stock upon the occurrence of an
Extraordinary Transaction (as defined in Section B.3). The foregoing election
shall be made by such holders giving the Corporation and each other holder of
Senior Redeemable Preferred Stock (or Series A Convertible Preferred Stock and
Series B Convertible Preferred Stock, as applicable) not less that five (5) days
prior written notice, which notice shall set forth the date for such redemption.

               b.   REDEMPTION PRICE.  Upon the election of the holders of

cause the Corporation to redeem the Senior Redeemable Preferred Stock pursuant

Preferred Stock in accordance with Section A.6, the Series B Convertible
Preferred Stock in accordance with Section B.6 and the Senior Redeemable
Preferred Stock in accordance with this Section C.4) shall be purchased,
redeemed or acquired by the Corporation and no monies shall be paid into or set
aside or made available for a sinking fund for the purchase, redemption or
acquisition thereof, other than pursuant to vesting or first refusal provisions
of agreements with employees, officers, directors or consultants of the
Corporation in which the Corporation repurchases shares of capital stock of the
Corporation at the original purchase price paid therefor by the applicable
individual.

               c.   INSUFFICIENT FUNDS FOR REDEMPTION.  If, at a Redemption

<PAGE>

is required hereunder, then it shall redeem such shares on a pro-rata basis
among the holders of Senior Redeemable Preferred Stock (and, if applicable, the
Series A Convertible Preferred Stock) in proportion to the full respective
redemption amounts to which they are entitled hereunder to the extent possible
and shall redeem the remaining shares to be redeemed as soon as the Corporation
is not prohibited from redeeming some or all of such shares under the General
Corporation Law of the State of Delaware. The shares of Senior Redeemable
Preferred Stock not redeemed shall remain outstanding and entitled to all of the
rights and preferences provided in this Article IV. In the event that the
Corporation fails for any reason to redeem shares for which redemption is
required pursuant to Section C.4, then during the period from the applicable
Redemption Date through the date on which such unredeemed shares are redeemed,
the applicable Redemption Price of such shares shall bear interest at the
greater of twelve percent (12%) per annum or five percent (5%) over the current
prime rate, which interest shall be compounded annually.

               d.   DIVIDEND AFTER REDEMPTION DATE.  From and after a
Redemption Date, no shares of Senior Redeemable Preferred Stock subject to
redemption shall be entitled to any further dividends pursuant to Section C.2
hereof; provided, however, that in the event that shares of Senior Redeemable
Preferred Stock are unable to be redeemed and continue to be outstanding in
accordance with Section C.4(c), such shares shall continue to be entitled to
dividends and interest thereon as provided in Sections C.4(b) and C.4(c) until

executed stock powers relating thereto), or shall deliver an Affidavit of Loss
with respect to such certificates at the principal executive office of the
Corporation or the office of the transfer agent for the Senior Redeemable
Preferred Stock or such office or offices in the continental United States of an
agent for redemption as may from time to time be designated by notice to the

amend or repeal the by-laws of the Corporation to the extent specified therein.

                                   ARTICLE VI

     Meetings of stockholders may be held within or without the State of
Delaware, as the by-laws may provide.  No action required to be taken or which
may be taken at any annual or special meeting of stockholders of the Corporation
may be taken, except at a duly convened meeting or by unanimous written consent
of the stockholders entitled to vote thereat with respect to the matters
submitted thereto, and the power of stockholders to act by other than unanimous
written consent without a meeting, is specifically denied, provided that the
foregoing shall not apply with respect to consent, approval or waiver rights of
the holders of the Series A Convertible Preferred Stock, Series B Convertible
Preferred Stock, Senior Redeemable Preferred Stock or Junior 

                                       32

for monetary damages for breach of his or her fiduciary duty as a Director of
the Corporation, except for liability (a) for any breach of the Director's duty
of loyalty to the Corporation or its stockholders, (b) for acts or omissions not
in good faith or which involve intentional misconduct or a knowing violation of
law, (c) under Section 174 of the General Corporation Law of the State of
Delaware, or (d) for any transaction from which the Director derived an improper
personal benefit. If the General Corporation Law of the State of Delaware is
amended after the effective date of this Amended and Restated Certificate of
Incorporation to authorize corporate action further eliminating or limiting the
personal liability of directors, then the liability of each past or present
Director of the Corporation shall be eliminated or limited to the fullest extent
permitted by the General Corporation Law of the State of Delaware, as so
amended.

     Any repeal or modification of this Article VIII by (a) the stockholders of
the Corporation or (b) an amendment to the General Corporation Law of the State
of Delaware (unless such statutory amendment specifically provides to the
contrary) shall not adversely affect any right or protection existing at the
time of such repeal or modification with respect to any acts or omissions
occurring either before or after such repeal or modification, of a person
serving as a Director prior to or at the time of such repeal or modification.

                                   ARTICLE IX

 ______________________________________________________________________________

                                   ARTICLE I

                               OFFICES AND AGENT

          1.   PRINCIPAL OFFICE.  The principal office of R&D Systems Company
(the "Corporation") may be located within or without the State of Delaware, as
designated by the board of directors. The Corporation may have other offices and
places of business at such places within or without the State of Delaware as
shall be determined by the directors.

          2.   REGISTERED OFFICE AND AGENT.  The Corporation shall have and
maintain at all times (a) a registered office in the State of Delaware, which
office shall be located at 1013 Centre Road, Wilmington, Delaware 19805, and (b)
a registered agent located at such address whose name is Corporation Service
Company, until changed from time to time as provided by the General Corporation
Law of the State of Delaware ("Delaware Corporation Law").

                                   ARTICLE II

                             STOCKHOLDERS MEETINGS

          1.   ANNUAL MEETINGS. The annual meeting of stockholders for the
election of directors and for the transaction of such other business as may
properly be brought before the meeting shall be held on such date and at such
time as determined by resolution of the board of directors.  If, at the place of
the meeting, this date shall fall upon a legal holiday, then such meeting shall
be held on the next succeeding business day at the same hour.  If no annual
meeting is held in accordance with the foregoing provisions, the board of
directors shall cause the meeting to be held as soon thereafter as convenient.
If no annual meeting is held in accordance with the foregoing provisions, a
special meeting may be held in lieu of the annual meeting, and any action taken
at that special meeting shall have the same effect as if it had been taken at
the annual meeting, and in such case all references in these Bylaws to the
annual meeting of stockholders shall be deemed to refer to such special meeting.

          2.   SPECIAL MEETINGS.  Special meetings of the stockholders of the
Corporation may be called for any purpose (including, without limitation, the
filling of board vacancies and newly created directorships) and may be held at
such time and place, within or without the State of Delaware, as shall be stated
in a notice of meeting or in a duly executed waiver of notice thereof.  Such
meetings may be called at any time by the board of directors or the president
and shall be called by the president upon the written request of holders of
shares entitled to cast not less than

                                       1.
<PAGE>
 
fifty percent of the votes at such special meeting or by the written request of
the holders of not less than fifty percent of the outstanding shares of any
series or class of the Corporation's stock; provided that if the president does
not so call the meeting, it may be called by the holders of shares entitled to
cast not less than fifty percent of the outstanding shares of any series or
class of the Corporation's stock. Such written request shall specify the purpose
or purposes of, and a proposed date for, the meeting and shall be delivered to
the president. Upon receipt of such written request, the president shall fix a
date and time for such meeting, which such date shall be within five business
days of the proposed date specified in the written request. A special meeting
shall in any event be held within five business days of the creation of a board
vacancy or new directorship.

          3.   PLACE OF MEETINGS.  All meetings of stockholders of the
Corporation shall be held within or without the State of Delaware as may be
designated by the board of directors, the president or the stockholders entitled
to call a meeting pursuant to Section 2 of this Article II, or, if not
designated, at the registered office of the Corporation.

          4.   NOTICE OF MEETING.  Except as otherwise provided in these Bylaws
or the Delaware Corporation Law, written notice of any meeting of stockholders
stating the place, date and hour of the meeting and, in the case of a special
meeting, the purpose for which the meeting is called, shall be delivered either
personally or by mail to each stockholder of record entitled to vote at such
meeting not less than ten (10) nor more than sixty (60) days before the date of
the meeting, by or at the direction of the board of directors, the president or
the secretary.  If mailed, such notice shall be deemed to be delivered as to any
stockholder of record when deposited in the United States mail addressed to the
stockholder at his address as it appears on the stock transfer books of the
Corporation, with postage prepaid.  When a meeting is adjourned to another time
or place, notice need not be given of the adjourned meeting if the time and
place thereof are announced at the meeting at which the adjournment is taken.
At the adjourned meeting the Corporation may transact any business which might
have been transacted at the original meeting.  If the adjournment is for more
than thirty (30) days, or if after the adjournment a new record date is fixed
for the adjourned meeting, a notice of the adjourned meeting shall be given to
each stockholder of record entitled to vote at the meeting.

          5.   WAIVER OF NOTICE.  Any stockholder, either before or after any
stockholders' meeting, may waive in writing notice of the meeting, and his
waiver shall be deemed the equivalent of giving notice.  Attendance at a meeting
by a stockholder shall constitute a waiver of notice, except when the
stockholder attends a meeting for the express purpose of objecting, at the
beginning of the meeting, to the transaction of any business because the meeting
is not lawfully called or convened.

          6.   FIXING OF RECORD DATE.  For the purpose of determining the
stockholders entitled to notice of or to vote at any meeting of stockholders or
any adjournment thereof, or to express consent to corporate action in writing
without a meeting, or entitled to receive payment of any dividend or other
distribution or allotment of any rights, or entitled to exercise any rights in
respect of any change, conversion or exchange of stock or for the purpose of any
other lawful action, the board of directors of the Corporation may fix, in
advance, a record date which shall be not more than sixty (60) days nor less
than ten (10) days prior to the date of such meeting, nor

                                       2.
<PAGE>
 
more than sixty (60) days prior to any other action. If no record date is fixed,
the record date for determining the stockholders entitled to notice of or to
vote at a meeting of stockholders shall be at the close of business on the day
next preceding the day on which notice is given, or, if notice is waived, at the
close of business on the day next preceding the day on which the meeting is
held. The record date for determining the stockholders entitled to express
consent to corporate action in writing without a meeting, when no prior action
by the board of directors is necessary, shall be the day on which the first
written consent is expressed. The record date for determining stockholders for
any other purpose shall be at the close of business on the day on which the
board of directors adopts the resolution relating thereto. A determination of
stockholders of record entitled to notice of or vote at a meeting of
stockholders shall apply to any adjournment of the meeting; provided, however,
that the board of directors may fix a new record date for the adjourned meeting.

          7.   STOCKHOLDERS LIST.  The officer who has charge of the stock
ledger of the Corporation shall prepare and make, at least ten (10) days before
every meeting of stockholders, a complete list of the stockholders entitled to
vote at the meeting, arranged in alphabetical order and showing the address of
each stockholder and the number of shares registered in the name of each
stockholder.  Such list shall be open to the examination of any stockholder, for
any purpose germane to the meeting, during ordinary business hours, for a period
of at least ten (10) days prior to the meeting, at a place within the city where
the meeting is to be held.  The list shall also be produced and kept at the time
and place of the meeting during the whole time thereof and may be inspected by
any stockholder who is present.

          8.   PROXIES.  A stockholder entitled to vote at a meeting of
stockholders or to express consent or dissent to corporate action in writing
without a meeting may authorize another person or persons to act for him by
proxy.  No proxy shall be voted or acted upon after three (3) years from its
date, unless the proxy provides for a longer period.

          9.   VOTING RIGHTS.  Each stockholder shall have one vote for each
share of stock entitled to vote held of record by such stockholder and a
proportionate vote for each fractional share so held, unless otherwise provided
in the Certificate of Incorporation.

          Persons holding stock in a fiduciary capacity shall be entitled to
vote the shares so held.  Persons whose stock is pledged shall be entitled to
vote, unless in the transfer by the pledgor on the books of the Corporation he
has expressly empowered the pledgee to vote thereon, in which case only the
pledgee, or his proxy, may represent such stock and vote thereon.

          If shares having voting power stand of record in the names of two or
more persons, whether fiduciaries, members of a partnership, joint tenants,
tenants in common, tenants by the entirety, or otherwise, or if two or more
persons have the same fiduciary relationship respecting the same shares, unless
the secretary of the Corporation is given written notice to the contrary and is
furnished with a copy of the instrument or order appointing them or creating the
relationship wherein it is so provided, their acts with respect to voting shall
have the following effect: (i) if only one votes, his act binds all; (ii) if
more than one vote, the act of the majority so voting binds all; and (iii) if
more than one vote, but the vote is evenly split on any particular matter, each
fraction may vote the securities in question proportionately, or any person
voting the

                                       3.
<PAGE>
 
shares or a beneficiary, if any, may apply to the Court of Chancery or any court
of competent jurisdiction in the State of Delaware to appoint an additional
person to act with the persons so voting the shares. The shares shall then be
voted as determined by a majority of such persons and the person appointed by
the Court. If a tenancy is held in unequal interests, a majority or even-split
for the purpose of this subsection shall be a majority or even-split in
interest.

          10.  QUORUM AND REQUIRED VOTE.  Except as otherwise provided by law,
the Certificate of Incorporation or these Bylaws, the holders of a majority of
the shares entitled to vote at the meeting, present in person or by proxy, shall
constitute a quorum for the transaction of business.  If a quorum is present,
the affirmative vote of a majority of the shares present or represented by proxy
at the meeting and entitled to vote on the subject matter shall be the act of
the stockholders, and, if there are two or more classes of stock entitled to
vote as separate classes, then, in the case of each such class, the affirmative
vote of a majority of the shares of that class present or represented by proxy
at the meeting shall be the vote of such class unless a different vote is
required by an express provision of law, the Certificate of Incorporation or
these Bylaws.

          11.  INFORMAL ACTION BY STOCKHOLDER.  Except as otherwise provided in
the Certificate of Incorporation, any action required by the provisions of
Delaware Corporation Law to be taken or any action which may be taken at a
stockholders' meeting may be taken without a meeting without prior notice and
without a vote, if a consent in writing, setting forth the action so taken,
shall be signed by the holders of outstanding shares having not less than the
minimum number of votes that would be necessary to authorize or take such action
at a meeting at which all shares entitled to vote thereon were present and
voted.  Prompt notice of the taking of the corporate action without a meeting by
less than unanimous consent shall be given to those stockholders who have not
consented in writing.  Any action taken pursuant to such written consent of the
stockholders shall have the same force and effect as if taken by the
stockholders at a meeting thereof.

                                  ARTICLE III

                               BOARD OF DIRECTORS

          1.   NUMBER, QUALIFICATIONS AND TERM OF OFFICE. Except as otherwise
provided in the Certificate of Incorporation or the Delaware Corporation Law,
the business and affairs of the Corporation shall be managed by or under the
direction of a board of directors.  Directors need not be stockholders of the
Corporation.  The board of directors shall consist of not less than three and
not more than seven members.  Except as otherwise provided in these Bylaws, each
director shall be elected at each annual meeting of stockholders and shall hold
such office until the next annual meeting of stockholders and until his
successor shall be elected and shall qualify.  No decrease in the member of
directors shall have the effect of shortening the term of any incumbent
director.

          2.   VACANCIES. Except as otherwise provided by the Certificate of
Incorporation of the Corporation or any amendments thereto, board vacancies and
newly created directorships resulting from any increase in the authorized number
of directors shall be filled by a majority vote of the holders of the
Corporation's outstanding stock entitled to vote thereon, and each

                                       4.
<PAGE>
 
director so chosen shall hold office until the next annual meeting of the
stockholders and until a successor is duly elected and qualified or until his or
her earlier death, resignation or removal as hereinafter provided.

          3.   RESIGNATION.  Any director may resign by delivering his written
resignation to the Corporation at its principal office addressed to the
president or secretary.  Such resignation shall be effective upon receipt unless
it is specified to be effective at some other time or upon the happening of some
other event.

          4.   REMOVAL.  Except as otherwise provided in the Certificate of
Incorporation or the Delaware Corporation Law, any director or the entire board
of directors may be removed with or without cause by the holders of a majority
of the shares then entitled to vote thereon at an election of directors.

          5.   COMPENSATION.  Directors may be paid such compensation for their
services and such reimbursements for expenses of attendance at meetings as the
Board of Directors may from time to time determine. No such payment shall
preclude any director from serving the Corporation in any other capacity and
receiving compensation therefor.

                                   ARTICLE IV

                             MEETINGS OF THE BOARD

          1.   PLACE OF MEETINGS.  The regular or special meetings of the board
of directors or any committee designated by the board shall be held at the
principal office of the Corporation or at any other place within or without the
State of Delaware that a majority of the board of directors or any such
committee, as the case may be, may designate from time to time by resolution.

          2.   REGULAR MEETINGS.  The board of directors shall meet each year
immediately after and at the same place as the annual meeting of the
stockholders for the purpose of electing officers and transacting such other
business as may come before the meeting.  The board of directors or any
committee designated by the board may provide, by resolution, for the holding of
additional regular meetings within or without the State of Delaware without
notice of the time and place of such meeting other than such resolution;
provided that any director who is absent when such resolution is made shall be
given notice of said resolution.

          3.   SPECIAL MEETINGS.  Special meetings of the board of directors or
any committee designated by the board may be held at any time and place, within
or without the State of Delaware, designated in a call by the chairman of the
board, if any, by the president or by a majority of the members of the board of
directors or any such committee, as the case may be.

          4.   NOTICE OF SPECIAL MEETING.  Except as otherwise provided by these
Bylaws or the laws of the State of Delaware, written notice of each special
meeting of the board of directors or any committee thereof setting forth the
time and place of the meeting shall be given to each director by the secretary
or by the officer or director calling the meeting not less than one (1) day

                                       5.
<PAGE>
 
prior to the time fixed for the meeting.  Notice of special meetings may be
either given personally, personally by telephone, or by sending a copy of the
notice through the United States mail or by telegram, telex or telecopy, charges
prepaid, to the address of each director appearing on the books of the
Corporation.  If mailed, such notice shall be deemed to be delivered when
deposited in the United States mail so addressed, with postage prepaid thereon.
If notice be given by telegram; such notice shall be deemed to be delivered when
the telegram, telex or telecopy, is delivered to the telegraph, telex or
telecopy operator.  Neither the business to be transacted at, nor the purpose
of, any regular or special meeting of the board of directors need be specified
in the notice or waiver of notice of such meeting.

          5.   WAIVER OF NOTICE.  A director may waive, in writing, notice of
any special meeting of the board of directors or any committee thereof, either
before, at, or after the meeting; and his waiver shall be deemed the equivalent
of giving notice.  By attending or participating in a regular or special
meeting, a director waives any required notice of such meeting unless the
director, at the beginning of the meeting, objects to the holding of the meeting
or the transacting of business at the meeting.

          6.   QUORUM AND ACTION AT MEETING.  At meetings of the board of
directors or any committee designated by the board, a majority of the total
number of directors, or a majority of the members of any such committee, as the
case may be, shall constitute a quorum for the transaction of business.  In the
event one or more of the directors shall be disqualified to vote at any meeting,
then the required quorum shall be reduced by one for each such director so
disqualified; provided, however, that in no case shall less than one-third (1/3)
of the number so fixed constitute a quorum.  If a quorum is present, the act of
the majority of directors in attendance shall be the act of the board of
directors or any committee thereof, as the case may be, unless the act of a
greater number is required by these Bylaws, the Certificate of Incorporation or
Delaware Corporation Law.  If a quorum shall not be present at any meeting of
the board of directors, the directors present thereat may adjourn that meeting
from time to time, without notice other than announcement at the meeting, until
a quorum shall be present.

          7.   COMMITTEES.  The board of directors may, by a resolution passed
by a majority of the whole board of directors designate one or more committees,
each committee to consist of one or more of the directors of the Corporation.
The board may designate one or more directors as alternate members of any
committee, who may replace any absent or disqualified member at any meeting of
the committee.  In the absence or disqualification of a member of a committee,
the member or members of the committee present at any meeting and not
disqualified from voting, whether or not he or they constitute a quorum, may
unanimously appoint another member of the board of directors to act at the
meeting in the place of the absent or disqualified member.  Any such committee,
to the extent provided in the resolution of the board of directors and subject
to the provisions of Delaware Corporation Law, shall have and may exercise all
the powers and authority of the board of directors in the management of the
business and affairs of the Corporation, and may authorize the seal of the
Corporation to be affixed to all such papers which may require it.  Each such
committee shall keep minutes and make such reports as the board of directors may
from time to time request.  Except as the board of directors may otherwise
determine, any committee may make rules for the conduct of its business, but,
unless otherwise

                                       6.
<PAGE>
 
provided by the directors or in such rules, its business shall be conducted as
nearly as possible in the same manner as is provided in these Bylaws for the
board of directors.

          8.   INFORMAL ACTION BY DIRECTORS.  Except as otherwise provided in
the Certificate of Incorporation, any action required or permitted by the
Delaware Corporation Law to be taken at any meeting of the board of directors or
any committee thereof may be taken without a meeting if all members of the board
or committee, as the case may be, consent to the action in writing, and the
written consents are filed with the minutes of proceedings of the board or
committee.

          9.   TELEPHONIC MEETINGS.  Directors or any members of any committee
designated by the board may participate in a meeting of the board or committee
by means of a conference telephone or similar communications equipment by which
all persons participating in the meeting can hear each other at the same time.
Such participation shall constitute presence in person at the meeting.

                                   ARTICLE V

                              OFFICERS AND AGENTS

          1.   ENUMERATION, ELECTION AND TERM.  The officers of the Corporation
shall consist of a president, a secretary, a treasurer and such other officers
with such other titles as may be deemed necessary or desirable by the board of
directors, including one or more vice presidents, assistant treasurers and
assistant secretaries and a chairman of the board.  Any number of offices may be
held by the same person and no officer need be a stockholder or a resident of
the State of Delaware.  Except as otherwise provided by law, the Certificate of
Incorporation or these Bylaws, each officer shall hold office until his
successor is elected and qualified or until his earlier death, resignation or
removal.  The officers of the Corporation shall be elected annually by the board
of directors at the first meeting of the board held after each annual meeting of
the stockholders.

          2.   GENERAL DUTIES.  All officers and agents of the Corporation, as
between themselves and the Corporation, shall have such authority and shall
perform such duties in the management of the Corporation as may be provided in
these Bylaws or as may be determined by resolution of the board of directors not
inconsistent with these Bylaws.  In all cases where the duties of any officer,
agent or employee are not prescribed by the Bylaws or by the board of directors,
such officer, agent or employee shall follow the orders and instructions of the
president.

          3.   VACANCIES.  The board of directors may fill any vacancy occurring
in any office for any reason and may, in its discretion, leave any vacancy
unfilled for such period as it may determine other than a vacancy in the office
of president or secretary.  The officer so selected shall hold office until his
successor is elected and qualified or until his earlier death, resignation or
removal.

                                       7.
<PAGE>
 
          4.   COMPENSATION.  The board of directors from time to time shall fix
the compensation of the officers of the Corporation.  The compensation of other
agents and employees of the Corporation may be fixed by the board of directors,
or by any committee designated by the board or by an officer to whom that
function has been delegated by the board.

          5.   RESIGNATION AND REMOVAL.  Any officer may resign by delivering
his written resignation to the Corporation at its principal office addressed to
the president or secretary.  Such resignation shall be effective upon receipt
unless it is specified to be effective at some other time or upon the happening
of some other event.  Any officer or agent of the Corporation may be removed,
with or without cause, by a vote of the majority of the members of the board of
directors whenever in its judgment the best interests of the Corporation may be
served thereby, but such removal shall be without prejudice to the contract
rights, if any, of the person so removed.  Election or appointment of an officer
or an agent shall not of itself create contract rights.

          6.   CHAIRMAN OF THE BOARD.  The chairman of the board, if any, shall
preside as chairman at meetings of the stockholders and the board of directors.
He shall, in addition, have such other duties as the board may prescribe that he
perform.  At the request of the president, the chairman of the board may, in the
case of the president's absence or inability to act, temporarily act in his
place.  In the case of death of the president or in the case of his absence or
inability to act without having designated the chairman of the board to act
temporarily in his place, the chairman of the board shall perform the duties of
the president, unless the board of directors, by resolution, provides otherwise.
If the chairman of the board shall be unable to act in place of the president,
the vice presidents may exercise such powers and perform such duties as provided
in Section 8 below.

          7.   PRESIDENT.  The president shall be the chief executive officer of
the Corporation and shall have general supervision of the business of the
Corporation.  In the event the position of chairman of the board shall not be
occupied or the chairman shall be absent or otherwise unable to act, the
president shall preside at meetings of the stockholders and directors and shall
discharge the duties of the presiding officer.  At each annual meeting of the
stockholders, the president shall give a report of the business of the
Corporation for the preceding fiscal year and shall perform whatever other
duties the board of directors may from time to time prescribe.
 
          8.   VICE PRESIDENTS.  Each vice president shall have such powers and
perform such duties as the board of directors may from to time prescribe or as
the president may from time to time delegate to him.  At the request of the
president, in the case of the president's absence or inability to act, any vice
president may temporarily act in his place.  In the case of the death of the
president, or in the case of his absence or inability to act without having
designated a vice president or vice presidents to act temporarily in his place,
the board of directors, by resolution, may designate a vice president or vice
presidents to perform the duties of the president.  If no such designation shall
be made, the chairman of the board of directors, if any, shall exercise such
powers and perform such duties, as provided in Section 7 above, but if the
Corporation has no chairman of the board of directors, or if the chairman is
unable to act in place of the president, all of the vice presidents may exercise
such powers and perform such duties.

                                       8.
<PAGE>
 
          9.   SECRETARY.  The secretary shall keep or cause to be kept in books
provided for that purpose, the minutes of the meetings of the stockholders,
executive committee, if any, and any other committees, and of the board of
directors; shall see that all notices are duly given in accordance with the
provisions of these Bylaws and as required by law; shall be custodian of the
records and of the seal of the Corporation and see that the seal is affixed to
all documents, the execution of which on behalf of the Corporation under its
seal is duly authorized and in accordance with the provisions of these Bylaws;
and, in general, shall perform all duties incident to the office of secretary
and such other duties as may, from time to time, be assigned to him by the board
of directors or by the president.  In the absence of the secretary or his
inability to act, the assistant secretaries, if any, shall act with the same
powers and shall be subject to the same restrictions as are applicable to the
secretary.

          10.  TREASURER.  The treasurer shall have custody of corporate funds
and securities.  He shall keep full and accurate accounts of receipts and
disbursements and shall deposit all corporate monies and other valuable effects
in the name and to the credit of the Corporation in the depository or
depositories of the Corporation, and shall render an account of his transactions
as treasurer and of the financial condition of the Corporation to the president
and/or the board of directors upon request.  Such power given to the treasurer
to deposit and disburse funds shall not, however, preclude any other officer or
employee of the Corporation from also depositing and disbursing funds when
authorized to do so by the board of directors.  The treasurer shall, if required
by the board of directors, give the Corporation a bond in such amount and with
such surety or sureties as may be ordered by the board of directors for the
faithful performance of the duties of his office.  The treasurer shall have such
other powers and perform such other duties as may be from time to time
prescribed by the board of directors or the president.  In the absence of the
treasurer or his inability to act, the assistant treasurers, if any, shall act
with the same authority and shall be subject to the same restrictions as are
applicable to the treasurer.

          11.  DELEGATION OF DUTIES.  Whenever an officer is absent, or
whenever, for any reason, the board of directors may deem it desirable, the
board may delegate the powers and duties of an officer to any other officer or
officers or to any director or directors.

                                   ARTICLE VI

               INDEMNIFICATION OF OFFICERS, DIRECTORS AND OTHERS

          1.   INDEMNIFICATION:  THIRD PARTY ACTIONS.  The Corporation shall
indemnify any person who was or is a party or is threatened to be made a party
to any threatened, pending or completed action, suit or proceeding, whether
civil, criminal, administrative or investigative (other than an action by or in
the right of the Corporation) by reason of the fact that he or she is or was a
director, officer, employee or agent, of the Corporation, or is or was serving
at the request of the Corporation as a director, officer, employee or agent of
another Corporation, partnership, joint venture, trust or other enterprise,
against expenses (including attorneys' fees), judgments, fines and amounts paid
in settlement actually and reasonably incurred by him or her in connection with
such action, suit or proceeding if he or she acted in good faith and in a manner
he or she reasonably believed to be in or not opposed to the best interest of
the Corporation, and,

                                       9.
<PAGE>
 
with respect to any criminal action or proceeding, had no reasonable cause to
believe his or her conduct was unlawful. The termination of any action, suit or
proceeding by judgment, order, settlement, conviction, or upon a plea of nolo
contendere or its equivalent, shall not, of itself, create a presumption that
the person did not act in good faith and in a manner which he or she reasonably
believed to be in or not opposed to the best interest of the Corporation, and,
with respect to any criminal action or proceeding, had reasonable cause to
believe that his or her conduct was unlawful.

          2.   INDEMNIFICATION:  DERIVATIVE ACTIONS.  The Corporation shall
indemnify any person who was or is a party or is threatened to be made a party
to any threatened, pending or completed action or suit by or in the fight of the
Corporation to procure a judgment in its favor by reason of the fact that he or
she is or was a director, officer, employee or agent of the Corporation, or is
or was serving at the request of the Corporation as a director, officer,
employee or agent of another Corporation, partnership, joint venture, trust or
other enterprise, against expenses (including attorneys' fees) actually and
reasonably incurred by him or her in connection with the defense or settlement
of such action or suit if he or she 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
Corporation and except that no indemnification shall be made in respect of any
claim, issue or matter as to which such person shall have been adjudged to be
liable to the Corporation unless and only to the extent that the court in which
such action or suit was brought shall determine upon application that, despite
the adjudication of liability but in view of all the circumstances of the case,
such person is fairly and reasonably entitled to indemnity for such expenses
which the court shall deem proper.

          3.   MANDATORY INDEMNIFICATION.  To the extent that a director or
officer, employee or agent of the Corporation has been successful on the merits
or otherwise in defense of any action, suit or proceeding referred to in
Sections 1 and 2 of this Article VI or in defense of any claim, issue or matter
therein, he or she shall be indemnified against expenses (including attorneys'
fees) actually and reasonably incurred by him or her in connection therewith.

          4.   AUTHORIZATION FOR INDEMNIFICATION.  Any indemnification under
Sections 1 and 2 of this Article VI (unless ordered by a court) shall be made by
the Corporation only as authorized in the specific case upon a determination
that indemnification of the director, officer, employee or agent is proper in
the circumstances because he or she has met the applicable standard of conduct
set forth in Sections I and 2 of this Article VI.  Such determination shall be
made (1) by the board of directors by a majority vote of a quorum consisting of
directors who were not parties to such action, suit or proceeding, or (2) if
such a quorum is not obtainable, or, even if obtainable a quorum of
disinterested directors so directs, by independent legal counsel in a written
opinion, or (3) by the stockholders.

          5.   ADVANCE PAYMENT OF EXPENSES.  Expenses (including attorneys'
fees) incurred in defending a civil, criminal, administrative or investigative
action, suit or proceeding may be paid by the Corporation in advance of the
final disposition of such action, suit or proceeding upon receipt of an
undertaking by or on behalf of the director or officer to repay such amount if
it shall ultimately be determined that he or she is not entitled to be
indemnified by the Corporation

                                      10.
<PAGE>
 
as authorized in Article VI. Such expenses (including attorneys' fees) incurred
by other employees and agents may be so paid upon such terms and conditions, if
any, as the board of directors deems appropriate.

          6.   NON-EXCLUSIVE.  The indemnification and advancement of expenses
provided by, or granted pursuant to, the other subsections of this Article VI
shall not be deemed exclusive of any other rights to which those seeking
indemnification or advancement of expenses may be entitled under any bylaw,
agreement, vote of stockholders or disinterested directors or otherwise, both as
to action in his or her official capacity and as to action in another capacity
while holding such office, and shall continue, unless otherwise provided when
authorized or ratified, as to a person who has ceased to be a director, officer,
employee or agent and shall inure to the benefit of the heirs, executors and
administrators of such a person.

          7.   INSURANCE.  The Corporation shall have power to purchase and
maintain insurance on behalf of any person who is or was a director, officer,
employee or agent of the Corporation or is or was serving at the request of the
Corporation as a director, officer, employee or agent of another Corporation,
partnership, joint venture, trust or other enterprise against any liability
asserted against him or her and incurred by him or her in any such capacity, or
arising out of his or her status as such, whether or not the Corporation would
have the power to indemnify him or her against such liability under the
provisions of this Article VI.

          8.   DEFINITIONS.  For purposes of this Article VI, the following
terms shall have the following meanings:

               (a) references to "the Corporation" shall include, in addition to
the resulting Corporation, any constituent Corporation (including any
constituent of a constituent) absorbed in a consolidation or merger which, if
its separate existence had continued, would have had power and authority to
indemnify its directors, officers, employees or agents so that any person who is
or was a director, officer, employee or agent of such constituent Corporation,
or is or was serving at the request of such constituent Corporation as a
director, officer, employee or agent of another Corporation, partnership, joint
venture, trust or other enterprise shall stand in the same position under the
provisions of this Article VI with respect to the resulting or surviving
Corporation as he or she would have with respect to such constituent Corporation
if its separate existence had continued;

               (b) references to "other enterprises" shall include employee
benefit plans;
               (c) references to "fines" shall include any excise taxes assessed
on a person with respect to an employee benefit plan;

               (d) references to "serving at the request of the Corporation"
shall include any service as a director, officer, employee or agent of the
Corporation which imposes duties on, or involves services by, such director,
officer, employee, or agent with respect to an employee benefit plan, its
participants, or beneficiaries; and

                                      11.
<PAGE>
 
               (e) a person who acted in good faith and in a manner he
reasonably believed to be in the interest of the participants and beneficiaries
of an employee benefit plan shall be deemed to have acted in a manner "not
opposed to the interests of the Corporation" as referred to in this Article VI.

                                  ARTICLE VII

                                 CAPITAL STOCK

          1.   CERTIFICATES OF STOCK.  The shares of the Corporation shall be
represented by certificates; provided that the board of directors of the
Corporation may, by resolution, provide that some or all of any or all classes
or series of its stock shall be uncertificated shares.  Any such resolution
shall not apply to shares represented by a certificate until such certificate is
surrendered to the Corporation.  Notwithstanding the adoption of such a
resolution by the board of directors, every holder of stock represented by
certificates and upon request every holder of uncertificated shares shall be
entitled to have a certificate signed by, or in the name of the Corporation by
the chairman or vice chairman of the board of directors, or the president or
vice president, and by the treasurer or an assistant treasurer, or the secretary
or an assistant secretary of the Corporation representing the number of shares
registered in certificate form.  Any or all the signatures on the certificate
may be a facsimile.  In case any officer, transfer agent, or registrar who has
signed or whose facsimile signature has been placed upon a certificate shall
have ceased to be such officer, transfer agent or registrar before such
certificate is issued, it may be issued by the Corporation with the same effect
as if he were such officer, transfer agent or registrar at the date of issue.

          2.   ISSUANCE OF STOCK.  Unless otherwise voted by the stockholders
and subject to the provisions of the Certificate of Incorporation, the whole or
any part of any unissued balance of the authorized capital stock of the
Corporation or the whole or any part of any unissued balance of the authorized
capital stock of the Corporation held in its treasury may be issued, sold,
transferred or otherwise disposed of by resolution of the board of directors in
such manner, for such consideration and on such terms as the board of directors
may determine.  Consideration for such shares of capital stock shall be
expressed in dollars, and shall not be less than the par value or stated value
therefor, as the case may be.  The par value for shares, if any, shall be stated
in the Certificate of Incorporation, and the stated value for shares, if any,
shall be fixed from time to time by the board of directors.

          3.   LOST CERTIFICATES.  The board of directors may direct a new
certificate to be issued in place of any previously issued certificate alleged
to have been destroyed or lost if the owner makes an affidavit or affirmation of
that fact and produces such evidence of loss or destruction as the board may
require.  The board, in its discretion, may as a condition precedent to the
issuance of a new certificate require the owner to give the Corporation a bond
as indemnity against any claim that may be made against the Corporation relating
to the allegedly destroyed or lost certificate.

                                      12.
<PAGE>
 
          4.   TRANSFER OF SHARES.  Subject to applicable law, shares of stock
of the Corporation may be transferred on its books upon the surrender to the
Corporation or its transfer agent of the certificates representing such shares,
if any, duly endorsed or accompanied by a written assignment or power of
attorney duly executed and with such proof of authority or authenticity of
signature as the Corporation or its transfer agent may reasonably require.  In
that event, the surrendered certificates shall be canceled, new certificates
issued to the persons entitled to them, if any, and the transaction recorded on
the books of the Corporation.

          5.   REGISTERED STOCKHOLDER.  The Corporation shall be entitled to
recognize the exclusive right of a person registered on its books as the owner
of shares to receive dividends, and to vote as such owner, and to hold liable
for calls and assessments a person registered on its books as the owner of
shares, and shall not be bound to recognize any equitable or other claim to or
interest in such share or shares on the part of the other person, whether or not
it shall have express or other notice thereof, except as otherwise provided by
the laws of the State of Delaware.

          6.   STOCK LEDGER.  An appropriate stock journal and ledger shall be
kept by the secretary or such registrars or transfer agents as the directors by
resolution may appoint in which all transactions in the shares of stock of the
Corporation shall be recorded.

          7.   RESTRICTION ON TRANSFER OF SHARES.  Notice of any restriction on
the transfer of the stock of the Corporation shall be placed on each certificate
of stock issued or in the case of uncertificated shares contained in the notice
sent to the registered owner of such shares in accordance with the provisions of
the Delaware Corporation Law.

                                  ARTICLE VIII

                              SEAL AND-FISCAL YEAR

the left of this paragraph of the Bylaws.

          9.   FISCAL YEAR.  The fiscal year of the Corporation shall be
determined by the board of directors and set forth in the minutes of the
directors.  Said fiscal year may be changed from time to time by the board of
directors in its discretion.

                                   ARTICLE IX

                                   DIVIDENDS

          Dividends upon the capital stock of the Corporation, subject to the
provisions of the Certificate of Incorporation, if any, may be declared by the
board of directors at any regular or special meeting, pursuant to law.
Dividends may be paid in cash, in property, or in shares of the capital stock,
subject to the provisions of the Certificate of Incorporation. Before payment of
any dividend, there may be set aside out of any funds of the Corporation
available for dividends such sum or sums as the directors from time to time, in
their absolute discretion, think proper as a

                                      13.
<PAGE>
 
reserve or reserves to meet contingencies, or for equalizing dividends, or for
repairing or maintaining any property of the Corporation, or for such other
purpose as the directors shall think in the best interest of the Corporation,
and the directors may modify or abolish any such reserve in the manner in which
it was created.

                                   ARTICLE X

                                   AMENDMENTS

          Subject to repeal or change by action of the stockholders, the board
of directors may amend, supplement or repeal these Bylaws or adopt new Bylaws,
and all such changes shall affect and be binding upon the holders of all shares
heretofore as well as hereafter authorized, subscribed for or offered.

Audited Financial Statements or disclosed elsewhere in this Agreement (including
the Schedules hereto), all of the accounts receivable of the Company represent
bona fide completed sales made in the ordinary course of business, are valid and
enforceable claims, subject to no set-off or counterclaim and fully-collectible
in the ordinary course. Except as disclosed on Schedule 2.8, the Company has no
                                               ------------

                                       5
<PAGE>
 
with it or from any of the Founders or any of its directors, officers, employees
or stockholders or any affiliates of the Founders of the Company.

     2.9    Title to Properties. The Company has good and marketable title to
            -------------------
or a valid leasehold interest in all of its properties and assets, free and
clear of all liens, restrictions or encumbrances, except as disclosed in
Schedule 2.9, and such properties and assets constitute all of the assets
- ------------
reasonably necessary for the conduct of the Company's business as presently
conducted and as presently contemplated by the Company to be conducted. All
machinery and equipment included in such properties which is necessary to the
business of the Company is in good condition and repair in all material respects
and all leases of real or personal property to which the Company is a party are
in full force and effect and afford the Company peaceful and undisturbed
possession of the subject matter of the lease. The Company is not in violation
of any material zoning, building or safety ordinance, regulation or requirement
or other law or regulation applicable to the operation of its owned or leased
properties, nor has the Company received any written notice of violation with
which it has not complied in all material respects.

     2.10   Tax Matters. Except as set forth in Schedule 2.10 attached hereto:
            -----------                         -------------

            (a)   The Company has paid or caused to be paid all federal,
state, local, foreign, and other taxes, including without limitation, income
taxes, estimated taxes, alternative minimum taxes, excise taxes, sales taxes,
franchise taxes, employment and payroll-related taxes, withholding taxes,
transfer taxes, and all deficiencies, or other additions to tax, interest, fines
and penalties owed by it (collectively, "Taxes"), required to be paid by it
through the date hereof whether disputed or not. All taxes and other assessments
and levies which the Company is required to withhold or collect have been
withheld and collected and have been paid over to the proper governmental
authorities. The Company has, in accordance with applicable law, timely and
properly filed all federal, state, local and foreign tax returns required to be
filed by it through the date hereof, all such returns correctly and accurately
set forth the amount of any Taxes relating to the applicable period and any
deductions from, or credits against any Taxes or taxable income relating to such
returns are valid and proper items of deduction or credit.

            (b)   Neither the Internal Revenue Service nor any other
governmental authority is now asserting or, to the knowledge of the Company,
threatening to assert against the Company any deficiency or claim for additional
Taxes. No claim has ever been made by an authority in a jurisdiction where the
Company does not file reports and returns that the Company is or may be subject
to taxation by that jurisdiction. There are no security interests on any of the
assets of the Company that arose in connection with any failure (or alleged
failure) to pay any Taxes. The Company has never entered into a closing
agreement pursuant to Section 7121 of the Internal Revenue Code of 1986, as
amended (the "Code"). The Company is not and never has been a "personal holding
company" as defined under Section 541 of the Code. There has not been any audit
of any tax return filed by the Company, no such audit is in progress, and the
Company has not been notified by any tax authority that any such audit is
contemplated or pending. No extension of time with respect to any date on which
a tax return was or is to be filed by the Company is in force, and no waiver or
agreement by the Company is in force for the extension of time for the
assessment or payment of any Taxes. The Company is not now and has never been a

                                       6
<PAGE>
 
member of an affiliated group filing a consolidated federal income tax return.
The Company does not have any liability for the Taxes of any person or entity
other than the Company.

            (c)   For purposes of this Agreement, all references to Sections
of the Code shall include any predecessor provisions to such Sections.

     2.11   Contracts and Commitments. Except as set forth on Schedule 2.11,
            -------------------------                         -------------
the Company is not a party to any: (1) customer contract, obligation or
commitment (whether written or oral) which involves an unfulfilled obligation to
provide goods or services valued in excess of $250,000 to any other party; (2)
contract, obligation or commitment (whether written or oral) involving an
obligation to make payments in excess of $250,000 to any other party; (3)

or stockholders of the Company or persons or organizations related to or
affiliated with the Founders or the Company; (9) leases; (10) powers of
attorney; or (11) pension, profit-sharing, retirement or stock option plans. To
the best knowledge of the Company, there is no basis for the termination,
expiration or modification of any such agreements within one year from the date
hereof, which termination, expiration or modification may have a material
adverse effect on the assets, liabilities, business, financial condition or
prospects of the Company. The Company is not in default under any contract,
obligation or commitment set forth on Schedule 2.11, and to the best knowledge
                                      -------------
of the Company, there is no state of facts which upon notice or lapse of time or
both would constitute such a default.

     2.12   Proprietary Rights; Employee Restrictions. Set forth in 
            -----------------------------------------
Schedule 2.12 is a list and brief description of all patents, patent rights,
- -------------
patent applications, trademarks, trademark applications, service marks, service
mark applications, trade names and copyrights owned by or registered in the name
of the Company, or of which the Company is a licensor or licensee (other than
with respect to "off-the-shelf" software which is generally available to the
general public at retail) or in which the Company has any right, and in each
case a brief description of the nature of such right. Except as set forth on
Schedule 2.12, the Company owns or possesses adequate licenses (other than with
- -------------
respect to "off-the-shelf" software which is generally available to the general
public at retail) to use, free and clear of claims or rights of any other
person, all patents, patent applications, trademarks, trademark applications,
service marks, service mark applications, trade names, copyrights, manufacturing
processes, programming processes and software, algorithms, formulae, trade
secrets and know how (collectively "Intellectual Property") necessary to the
conduct of its business as presently conducted and as proposed to be conducted.
Except as disclosed in Schedule 2.12, all Intellectual Property that is used or
                       -------------
incorporated into the Company's products or products actively under development
and which is proprietary to the Company was developed by or for the Company by
the current or former employees, consultants or independent contractors of the
Company or its predecessors in interests and is owned exclusively by the
Company, free and clear of claims or rights of any other person. The Company is
not aware of any infringement by any other person of any rights of the Company
under any Intellectual Property. No claim is pending or to the best of the
Company's knowledge threatened against the Company nor has the Company received
any notice from any third parties, 

                                       7
<PAGE>
 
to the effect that any Intellectual Property owned or licensed by the Company,
or which the Company otherwise has the right to use, or the operation, products
or services of the Company infringe upon or conflict with the asserted rights of
any other person under any Intellectual Property, and, to the best knowledge of
the Company and the Founders, there is no basis for any such claim (whether or
not pending or threatened). No claim is pending or to the best of the Company's
knowledge threatened against the Company, nor has the Company received any
notice from any third parties, to the effect that any Intellectual Property
owned or licensed by the Company, or which the Company otherwise has the right
to use, is invalid or unenforceable by the Company, as the case may be, and, to
the best knowledge of the Company and the Founders, there is no basis for any
such claim (whether or not pending or threatened).

         All licenses or other agreements under which the Company is granted
rights in Intellectual Property are listed in Schedule 2.12. All such licenses
                                              -------------
or other agreements are in full force and effect, to the best of the Company's
knowledge, there is no material default by any party thereto, and, except as set
forth on Schedule 2.12, to the best of the Company's knowledge, all of the
         -------------
rights of the Company thereunder are freely assignable. True and complete copies
of all such licenses or other agreements, and any amendments thereto, have been
provided to the Investors and, neither the Company nor the Founders have any
reason to believe that the licensors under such licenses and other agreements do
not have and did not have all requisite power and authority to grant the rights
purported to be conferred thereby.

         All licenses or other agreements under which the Company has granted
rights to others in Intellectual Property (including all end user agreements)
are listed in Schedule 2.12. All of said licenses or other agreements are in
              -------------
full force and effect, to the best of the Company's knowledge, there is no
material default by any party thereto, and, except as set forth on Schedule
                                                                   --------
2.12, to the best of the Company's knowledge, all of the rights of the Company
- ----
with respect to Trend product contracts are freely assignable. True and complete
copies of all such licenses or other agreements, and any amendments thereto,
have been made available to the Investors.

         All material technical information developed by or belonging to the
Company and which is material to the business of the Company which has not been
patented or copyrighted has been kept confidential. To the best of the Company's
knowledge, the Company is not making unlawful use of any Intellectual Property
of any other person, including without limitation any former employer of any
past or present employees of the Company. Except as disclosed in Schedule 2.12,
                                                                 -------------
to the best of the Company's knowledge, neither the Company nor any of its
employees, officers or consultants has any agreements or arrangements with
former employers of such employees, officers or consultants relating to any
Intellectual Property of such employers, which materially interfere or conflict
with the performance of such employee's or consultant's duties for the Company
or results in any former employers of such employees and consultants having any
rights in, or claims on, the Company's Intellectual Property. To the best of the
Company's knowledge, the activities of the Company's employees, officers and
consultants do not violate any agreements or arrangements which any such
employees have with former employers. The Company has taken commercially
reasonable steps required to establish and preserve its ownership of all of the
Intellectual Property; each current employee and officer of the Company, each
former employee and officer of the Company who was employed by the 

                                       8
<PAGE>
 
Company at any time and, except with respect to the SHIMS products, after
December 31, 1992 and each of the Company's current and former consultants and
independent contractors involved in development of any of the Intellectual
Property (limited, with respect to the SHIMS products to consultants and
contractors employed by the Company or its predecessor after December 31, 1992)
has executed an agreement regarding confidentiality, proprietary information and
assignment of inventions to the Company and, to the knowledge of the Company and
the Founders, none of such employees, consultants and independent contractors
are in violation of such agreements.

expressly disclosed in Schedule 2.12 hereto: (a) the Company has taken
                       -------------
reasonable security measures to guard against unauthorized disclosure or use of
any of the Intellectual Property; and (b) the Company has no reason to believe
that any person (including without limitation any former employee of the
Company) has unauthorized possession of any of the Intellectual Property, or any
part thereof, or that any person has obtained unauthorized access to any of the
Intellectual Property.

         2.13 Litigation. Except as disclosed in Schedule 2.13, there is no
              ----------                         -------------
litigation or governmental proceeding or investigation pending against the
Company, the Founders or any officer of the Company, or, to the best knowledge
of the Company and the Individual Founders, threatened against the Company, the
Founders or any officer of the Company, which may call into question the
validity or hinder the enforceability or performance of this Agreement or the
agreements and transactions contemplated hereby or which could have a material
adverse effect on the assets, liabilities, business, condition (financial or
otherwise) or prospects of the Company; nor, to the best knowledge of the
Company and the Founders, has there occurred any event nor does there exist any
condition on the basis of which any litigation, proceeding or investigation
might properly be instituted.

         2.14 Offerees. Except as set forth on Schedule 2.14, neither the
              --------                         -------------

has in the past offered for sale or solicited offers to buy any securities of
the Company so as to bring the offer, issuance or sale of the Preferred Shares
or the Conversion Shares, as contemplated by this Agreement, within the
provisions of Section 5 of the Securities Act, unless such offer, issuance or

issuance and sale of its Common Stock, Preferred Shares, and other securities
heretofore issued and to be issued upon the closing of this Agreement. The

2.15, the Company has all franchises, permits, licenses and other rights and
- ----
privileges necessary to permit it to own its property and to conduct its
business as it is presently conducted by the Company except where the failure to
possess such rights and privileges would not have a material adverse effect on
the Company. The Company is not in material violation, in any respect, of any
material law, regulation, authorization or order of any public authority. The
Company is in compliance, in

expressly permitted by Section 4.11(b) hereof it will not sell or issue any (i)
shares of capital stock of the Company, or bonds, certificates of indebtedness,
debentures or other securities convertible into or exchangeable for capital
stock of the Company, or options, warrants or rights carrying any rights to
purchase capital stock or convertible or exchangeable securities of the Company
(collectively, "Additional Equity Securities"), other than in connection with a
Qualified Public Offering or as otherwise provided in Section 4.11(b) hereof or
(ii) notes, bonds, certificates of indebtedness, debentures or other debt
securities (collectively, "Additional Debt Securities" and together with
Additional Equity Securities, "Additional Securities") unless (x) the Company
shall have received a bona fide arms-length offer (which may be in response to a
solicitation by the Company) to purchase such Additional Securities from a third
party, and (y) the Company first submits a written offer to the Investors and
the Lammle Entities identifying the third party to whom such Additional
Securities are proposed to be sold and the terms of the proposed sale, and
offering to the Investors and the Lammle Entities the opportunity to purchase
such securities on terms and conditions, including price, not less favorable
than those on which the Company proposes to sell such securities to the third
party. Each of the Investors and the Lammle Entities shall have the right to
purchase its proportionate share of such securities based on the ratio which the
Conversion Shares and shares of Common Stock, respectively, of the Company owned
or obtainable by such Investor or Founder owned by it bears to the sum of all
Conversion Shares and shares of Common Stock owned by all Investors and Founders
immediately prior to such issuance. Any Investor may transfer its right to be
offered any such opportunity to any transferee of shares of its Preferred
Shares. The Company's offer to the Investors and the Lammle Entities shall
remain open and irrevocable for a period of at least 45 days. Any securities so
offered to the Investors and the Lammle Entities which are not purchased
pursuant to such offer shall be offered to the Investors and the Lammle Entities
wishing to purchase any such securities, and thereafter may be sold by the
Company to the third party originally named or assigned in the offer to the
Investors and the Lammle Entities on terms and conditions, including price, not
more favorable to the third party than those set forth in such offer at any time
within 75 days following the date of such offer, but may not be sold to any
other person or on terms and conditions, including price, that are more
favorable to the purchaser than those set forth in such offer or after such
75-day period without renewed compliance with this Section 4.11. Notwithstanding

                                      21
<PAGE>
 
anything contained herein to the contrary, an Investor within an Investor group
shall have the right to purchase any shares with respect to which another
Investor within the same Investor group elects not to purchase hereunder.

              (b) Notwithstanding the foregoing, the Company may (i) issue, or
issue options, warrants or rights to subscribe for, up to an aggregate of
1,327,465 shares of its Common Stock to officers, directors, employees,
consultants or agents of the Company pursuant to the terms of the Company's
Stock Option Plan and Section 4.8 hereof and issue shares of its Common Stock
upon the exercise of such stock options, (ii) issue Conversion Shares upon the
conversion of the Preferred Shares, (iii) declare, make or issue a dividend or
other distribution payable in shares of the Common Stock in respect of
outstanding shares of the Common Stock or the Preferred Stock in accordance with

Offering, (v) issue shares of its Common Stock or other securities in connection
with the acquisition of any other corporation or business concern, whether by

reorganization as long as the beneficial owners of the Company's outstanding
capital stock immediately prior to such transaction hold no less than fifty-one
percent (51%) of the voting power of the outstanding capital stock of the
Company immediately after such transaction, or (vi) with the prior consent of a
a majority-in-interest of the Investors, issue, or issue options, warrants or
rights to subscribe for, shares of its Common Stock in connection with any debt,
capital lease or other similar financing transaction, without offering the
Investors the opportunity to purchase their proportionate share of such shares
or options under this Section 4.11.

         4.12 Stockholders' Agreement, Non-Competition Agreements and
              -------------------------------------------------------
Confidentiality and Proprietary Rights Agreements. The Company will diligently
- -------------------------------------------------
enforce all of its rights under the Stockholders' Agreement described in Section
3.5 hereof, and the agreements described in Section 3.6 hereof. The Company will
not effect any transfer of any of the outstanding capital stock of the Company
on the stock record books of the Company unless such transfer is made in
accordance with the terms of the Stockholders' Agreement referred to in Section
3.5 hereof. The Company will not waive or release any rights under, or consent
to the amendment of, any such agreement without the written consent of a
majority-in-interest of the Investors.

         4.13 Distributions on, and Redemptions of, Capital Stock. Except as
              ---------------------------------------------------
otherwise expressly provided in this Agreement or in Exhibit B hereto, the
                                                     ---------
Company will not declare or pay any dividends or make any distributions of cash,
property or securities of the Company with respect to any shares of its Common
Stock or any other class of its capital stock, or directly or indirectly redeem,
purchase, or otherwise acquire for consideration any shares of its Common Stock
or any other class of its capital stock; provided, however, that this
restriction shall not apply to the repurchase of shares of the Common Stock
pursuant to stock repurchase agreements under which the Company has the option
to repurchase such shares upon the occurrence of certain events, including the
termination of employment and involuntary transfers, by operation of law,
provided that the repurchase price paid by the Company does not exceed the
purchase price paid to the Company for such shares. Any redemption, repurchase
or other acquisition by

<PAGE>
 
the Company of any shares of its capital stock shall be made in compliance with

(a) sell, lease or otherwise dispose of (whether in one transaction or a series
of related transactions) all or substantially all of its assets, (b) merge
with or into or consolidate with another entity (except into or with a

for borrowed money (other than the Senior Debt), capital leases, or other
similar commitments or obligations, which, for any one such borrowing or series
of related borrowings, is in excess of $300,000, (g) grant or permit to exist
any liens, security interests or encumbrances on any of the Company's assets or
properties, except as permitted by the terms of the Senior Debt as in effect on
the date hereof or except for purchase money security interests, or (h) enter
into any agreement with any party which by its terms restricts the payments due
the holders of the Preferred Shares pursuant to Exhibit B hereto.

         4.15 No Amendments to Certificate of Incorporation. The Company will
              ---------------------------------------------

majority-in-interest of the Preferred Shares and Conversion Shares.

         4.16 Capital Expenditures. The Company will not, without the prior
              --------------------
approval of the Board of Directors of the Company, make any expenditures for
fixed or capital assets, or any commitments for such expenditures, exceeding an
amount of $100,000 for any one such expenditure or series of related
expenditures in any one year.

         4.17 Life Insurance. The Company will, within thirty (30) days after

SECTION 5.  INVESTOR REPRESENTATIONS
            ------------------------

         In order to induce the Company and the Founders to enter into this
Agreement, each Investor hereby severally represents with respect to such
Investor's purchase of Securities hereunder that:

                  (a) The execution of this Agreement and all other documents
executed pursuant hereto has been duly authorized by all necessary action on the
part of the Investor, has 


                                      23
<PAGE>
 
been duly executed and delivered, and constitutes a valid, binding and
enforceable agreement of the Investor.

                  (b) The Investor is acquiring the Preferred Shares for its own
account, for investment, and not with a present view to any "distribution"
thereof within the meaning of the Securities Act. The Investor was not formed or
organized for the purpose of acquiring the Preferred Shares.

                  (c) The Investor understands that because the Preferred Shares
have not been registered under the Securities Act, it cannot dispose of any or
all of the Preferred Stock or the Common Stock issuable upon conversion thereof
unless such securities are subsequently registered under the Securities Act or
exemptions from such registration are available. The Investor understands that
each certificate representing the Preferred Stock will bear the following legend
or one substantially similar thereto:

                  The securities represented by this certificate have not been
                  registered under the Securities Act of 1933 (the "Act"). These
                  securities have been acquired for investment and not with a
                  view to distribution or resale, and may not be sold,
                  mortgaged, pledged, hypothecated or otherwise transferred
                  without an effective registration statement for such
                  securities under the Act or the availability of an exemption
                  from such registration requirements.

                  (d) The Investor is sufficiently knowledgeable and experienced
in the making of venture capital investments so as to be able to evaluate the
risks and merits of its investment in the Company, and is able to bear the
economic risk of loss of its investment in the Company.

                  (e) The Investor has been advised that the Preferred Shares
have not been and are not being registered under the Act or under the "blue sky"
laws of any jurisdiction and that the Company in issuing the Preferred Stock is
relying upon, among other things, the representations and warranties of the
Investors contained in this Section 5.

                  (f) No broker, finder, agent or similar intermediary has acted
on behalf of an Investor in connection with this Agreement or the transactions
contemplated hereby and there are no brokerage commissions, finder's fees or
similar fees or commissions payable in connection therewith.

                  (g) The Investor is an "accredited investor" as defined in
Regulation D of the Securities Act.

                  (h) The Investor is not "controlled" by any other entity for
purposes of the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as
amended.

                  (i) Advent VII L.P., Advent Atlantic and Pacific II L.P.,
Advent Atlantic and Pacific III, L.P., Advent New York L.P., Summit Ventures IV,
L.P., Summit Investors III, L.P. 


                                      24

"institutional buyers" as described in the Massachusetts Uniform Securities Act.

                  (j)      Technology Leaders II L.P. and Technology Leaders II
Offshore C.V. represent that they are "institutional investors" as described in
the Pennsylvania Securities Act.

                  (a) any inaccuracy in or breach of any representation or
warranty made by the Founders or the Company in this Agreement, or in any
Schedule, exhibit or certificate delivered by or on behalf of the Founders or
the Company as part of or pursuant to this Agreement (collectively, "Warranty
Claims");

                  (b) any breach of the representations set forth in Section 2.4
relating to the capital stock and capitalization of the Company and Section 2.16
relating to investment banking or brokerage fees or any covenant or agreement
made by or on behalf of the Founders or the Company in this Agreement, or in any
Schedule, exhibit or certificate delivered by or on behalf of the Founders or
the Company as part of or pursuant to this Agreement;

                  (c) any liability of the Company for Taxes arising from an
event or transaction prior to the Closing or as a result of the Closing which
have not been paid by the Company prior to the Closing, including without
limitation, any increase in Taxes due to the unavailability of any loss or
deduction claimed by the Company; or

                  (d)      any liability of the Company arising from the defense
or disposition of Data Dynamics, Inc. v. R&D Systems Company (which for purposes
                  ------------------------------------------
of this Section 6 shall be deemed to be a Warranty Claim).


                                      25
<PAGE>
 
         The rights of Indemnified Parties to recover indemnification in respect
of any occurrence referred to in either of clauses (b), (c) and (d) of this
Section 6.2 shall not be limited by the fact that such occurrence may constitute
an inaccuracy in or breach of any representation, warranty or agreement referred
to in clause (a) of this Section 6.2.

         6.3      Limitations on Indemnification.
                  ------------------------------

                  (a)      The right of Indemnified Parties to indemnification
under Section 6.2 shall be subject to the following provisions:

                           (i) Indemnification with respect to Warranty Claims
         shall expire on the earlier to occur of (A) a Qualified Public Offering
         or (B) thirty (30) days after receipt by the Company of the audited
         financial statements of the Company for the fiscal year ending December
         31, 1996; provided, however, that the limitation of this clause (i)
         shall not apply to (x) Warranty Claims involving fraud, intentional
         misrepresentation or breach of Section 2.4 or 2.16, (y) Taxes, for
         which the period for making such claims shall expire on the date which
         is six (6) months after the termination of the applicable statute of
         limitations relating thereto and (z) claims arising from the defense or
         disposition of Data Dynamics, Inc. v. R&D Systems Company if such
                        ------------------------------------------
         lawsuit has not been finally adjudicated as of such date (in which
         event appropriate reserves for the estimated liabilities, losses and
         expenses arising from such lawsuit shall remain in escrow (which
         reserves will not, in any event exceed $650,000)). If prior to the
         relevant date of expiration a specific state of facts shall have become
         known which may constitute or give rise to any Warranty Claim as to
         which indemnity may be payable and an Indemnified Party shall have
         given notice of such facts to the Founders, then the right to
         indemnification with respect thereto shall remain in effect without
         regard to when such matter shall have been finally determined and
         disposed of, according to the date on which notice of the applicable
         claim is given.

                           (ii) No indemnification shall be payable with respect
         to Warranty Claims (other than those involving fraud, intentional
         misrepresentation, breach of Section 2.4 or 2.16 or Taxes) to
         Indemnified Parties unless the total of all Warranty Claims shall
         exceed $500,000 in the aggregate, whereupon only the amount of such
         excess claims shall be recoverable in accordance with the terms hereof;
         provided, however, that with respect to indemnification claims relating
         --------  -------
         to Section 6.2(d) hereof, indemnification shall be available from the
         first dollar of loss or claim, notwithstanding anything herein to the
         contrary.

                           (iii) The Founders shall not be obligated to
         indemnify Indemnified Parties for Warranty Claims (other than any such
         claims involving fraud, intentional misrepresentations, or Taxes) after
         the cumulative amount of all amounts paid by the Founders to
         Indemnified Parties with respect thereto exceeds FOUR MILLION NINE
         HUNDRED THOUSAND DOLLARS ($4,900,000) and the sole remedy with respect
         to any such claim described in this Section 6.3(a)(iii) shall be as
         provided in the Escrow Agreement; provided, further, that the Founders
                                           --------  -------
         shall not be obligated to indemnify 


                                      26
<PAGE>
 
         Indemnified Parties for indemnification claims relating to Section
         6.2(d) in an amount in excess of Six Hundred and Fifty Thousand Dollars
         ($650,000).

                           (iv) The limitations herein with respect to certain
         Warranty Claims shall not limit the rights of any Indemnified Party
         with respect to any other claims arising under provisions of Section
         6.2 and the Founders shall not have any right of contribution from, or
         claims against, the Company with respect to their indemnification
         claims hereunder.

         (b) In the event any claim for indemnification hereunder arises under
more than one provision of Section 6.2 and as such may be subject to limitations
pursuant to this Section 6.3 if deemed to arise under a particular provision but
not if deemed to arise under a different provision, then the claim shall be
deemed to arise under the provision to which no restrictions or the least
restrictive provisions apply.

         6.4 Notice; Defense of Claims. Promptly after receipt by an indemnified
             -------------------------
party of notice of any third party or other claim, liability or expense to which
the indemnification obligations hereunder would apply, including in connection
with any governmental proceeding, the indemnified party shall give notice
thereof in writing to the indemnifying party or parties, but the omission to so
notify the indemnifying party or parties promptly will not relieve the
indemnifying party or parties from any liability except to the extent that the
indemnifying party or parties shall have been materially prejudiced as a result
of the failure or delay in giving such notice. Such notice shall state the
information then available regarding the amount and nature of such claim,
liability or expense and shall specify the provision or provisions of this
Agreement under which the liability or obligation is asserted.

         In the case of any third party claim, if within twenty (20) days after
receiving the notice described in the preceding paragraph the indemnifying party
or parties (i) give written notice to the indemnified party or parties stating
that they intend to defend in good faith against such claim, liability or
expense at their own cost and expense and (ii) provide assurance and security
reasonably acceptable to such indemnified party or parties that such
indemnification will be paid fully and promptly if required and such indemnified
party or parties will not incur cost or expense during the proceeding, then
counsel for the defense shall be selected by the indemnifying party or parties
(subject to the consent of such indemnified party or parties which consent shall
not be unreasonably withheld) and such indemnified party or parties shall not be
required to make any payment with respect to such claim, liability or expense as
long as the indemnifying party or parties are conducting a good faith and
diligent defense at their own expense; provided, however, that the assumption of
defense of any such matters by the indemnifying party or parties shall relate
solely to the claim, liability or expense that is subject or potentially subject
to indemnification. If the indemnifying party or parties assume such defense in
accordance with the preceding sentence, they shall have the right, with the
consent of such indemnified party or parties, which consent shall not be
unreasonably withheld, to settle all Indemnifiable matters related to claims by
third parties which are susceptible to being settled provided the indemnifying
party or parties' obligation to indemnify such indemnified party or parties
therefor will be fully satisfied and the settlement includes a complete release
of such indemnified party or parties. The 


                                      27
<PAGE>
 
indemnifying party or parties shall keep such indemnified party or parties
apprised of the status of the claim, liability or expense and any resulting
suit, proceeding or enforcement action, shall furnish such indemnified party or
parties with all documents and information that such indemnified party or
parties shall reasonably request and shall consult with such indemnified party
or parties prior to acting on major matters, including settlement discussions.
Notwithstanding anything herein stated, such indemnified party or parties shall
at all times have the right to fully participate in such defense at its own
expense directly or through counsel; provided, however, if the named parties to
the action or proceeding include both the indemnifying party or parties and the
indemnified party or parties and representation of both parties by the same
counsel would be inappropriate under applicable standards of professional
conduct, the expense of separate counsel for such indemnified party or parties
shall be paid by the indemnifying party or parties. If no such notice of intent
to dispute and defend is given by the indemnifying party or parties, or if such
diligent good faith defense is not being or ceases to be conducted, such
indemnified party or parties shall, at the expense of the indemnifying party or
parties, undertake the defense of (with counsel selected by such indemnified
party or parties), and shall have the right to compromise or settle, such claim,
liability or expense with the consent of the Indemnifying Party, which will not
be unreasonably withheld, provided, however, if such consent is requested and
the Indemnifying Party does not respond within ten (10) business days, such
Indemnifying Party shall be deemed to have consented. If such claim, liability
or expense is one that by its nature cannot be defended solely by the
indemnifying party or parties, then such indemnified party or parties shall make
available all information and assistance that the indemnifying party or parties
may reasonably request and shall cooperate with the indemnifying party or
parties in such defense.

         6.5 Satisfaction of Indemnification Obligations; Disputed Claims. Any
             ------------------------------------------------------------
indemnity payable pursuant to this Section 6 shall be paid in accordance with
the Escrow Agreement within the later of (a) fifteen (15) days after the
indemnified party's request therefor or (b) ten (10) days prior to the date on
which the Loss upon which the indemnity is based is required to be satisfied by
the indemnified party. Notwithstanding anything to the contrary set forth in
this Agreement, any dispute relating to any indemnification claim hereunder
shall be resolved in accordance with the provisions of the Escrow Agreement.

SECTION 7.  GENERAL
            -------

         7.1 Amendments, Waivers and Consents. For the purposes of this
             --------------------------------
Agreement and all agreements, documents and instruments executed pursuant
hereto, except as otherwise specifically set forth herein or therein, no course
of dealing between the Company or the Founders on the one hand and any Investor
on the other and no delay on the part of any party hereto in exercising any
rights hereunder or thereunder shall operate as a waiver of the rights hereof
and thereof. No covenant or other provision hereof or thereof may be waived
otherwise than by a written instrument signed by the party so waiving such
covenant or other provision; provided, however, that except as otherwise
provided herein or therein, changes in or additions to, and any consents
required by, this Agreement may be made, and compliance with any term, covenant,
condition or provision set forth herein may be omitted or waived (either
generally or in 


                                      28
<PAGE>
 
a particular instance and either retroactively or prospectively) by a consent or
consents in writing signed by the Investors holding a majority-in-interest of
the Preferred Shares (including for such purposes, on a proportional basis, any
Conversion Shares into which any of the Preferred Shares have been converted
that have not been sold to the public) and (in the case of any such change or
addition) the Company; provided, however, that the amendment, modification or
                       --------  -------
waiver of any provision which by its terms requires the consent or approval of
more than a majority-in-interest of the Investors shall only be effective if it
is signed by holders of such requisite percentage. All references in this
Agreement to a majority-in-interest of the Investors refer to Investors holding
a- majority-in-interest of the outstanding Preferred Shares and Conversion
Shares on an as converted basis. Any amendment or waiver effected in accordance
with this Section 7.1 shall be binding upon each holder of Preferred Shares
purchased under this Agreement at the time outstanding (including securities
into which such Preferred Shares have been converted), each future holder of all
such securities and the Company.

         7.2 Survival of Representations, Warranties and Covenants;
             ------------------------------------------------------
Assignability of Rights. All covenants, agreements, representations and
- -----------------------
warranties of the Company and/or the Founders made herein and in the
certificates, lists, exhibits, schedules or other written information delivered
or furnished by or on behalf of the Company and/or the Founders to any Investor
in connection herewith shall be deemed material and to have been relied upon by
such Investor, and, except as otherwise provided in this Agreement, shall
survive the delivery of the Securities regardless of any instruction and shall
not merge in the performance of any obligation and shall bind the Company's and
the Founders' successors, assigns and heirs, whether so expressed or not, and,
except as otherwise provided in this Agreement, all such covenants, agreements,
representations and warranties shall inure to the benefit of the Investors'
successors and assigns and to transferees of the Securities, whether so
expressed or not. The representations and warranties made by the Investors in
Section 5 of this Agreement shall survive the delivery of the Securities and
shall bind the Investors' successors and assigns and shall inure to the benefit
of the Company's successors and assigns.

         7.3 Governing Law. Except for Delaware corporate law matters relating
             -------------
to the Company which shall be governed by and construed in accordance with the
Delaware General Corporation Law, this Agreement shall be deemed to be a
contract made under, and shall be construed in accordance with, the laws of The
Commonwealth of Massachusetts (without giving effect to principles of conflicts
of law). Each party also waives trial by jury in any action relating to this
Agreement

         7.4 Section Headings; Counterparts. The descriptive headings in this
             ------------------------------
Agreement have been inserted for convenience only and shall not be deemed to
limit or otherwise affect the construction of any provision thereof or hereof.
This Agreement may be executed simultaneously in any number of counterparts,
each of which when so executed and delivered shall be taken to be an original;
but such counterparts shall together constitute but one and the same document.

         7.5 Notices and Demands. Any notice or demand which, by any provision
             -------------------

         7.6 Severability. Whenever possible, each provision of this Agreement
             ------------
shall be interpreted in such a manner as to be effective and valid under
applicable law, but if any provision of this Agreement shall be deemed
prohibited or invalid under such applicable law, such provision shall be
ineffective to the extent of such prohibition or invalidity, and such
prohibition or invalidity shall not invalidate the remainder of such provision
or the other provisions of this Agreement.

         7.7 Expenses. The Founders shall pay all attorneys' fees (including
             --------
costs) that each of the Company, the Founders and the Investors incurs with

executed pursuant hereto and the Founders shall pay all other costs and expenses
that they and the Company incur with respect to the negotiation, execution,
delivery and performance of this Agreement and the agreements, documents and
instruments contemplated hereby or executed pursuant hereto (including, without
limitation, any amounts payable to The Wallach Company).

         7.8 Integration. This Agreement together with the Stockholders'
             -----------
Agreement, including the exhibits, documents and instruments referred to herein
or therein, constitutes the entire agreement, and supersedes all other prior
agreements and understandings, both written and oral, among the parties with
respect to the subject matter hereof.

                           REGARDING CONFIDENTIALITY
                            AND PROPRIETARY RIGHTS


Employee Name:

Date:


          WHEREAS, certain investors have agreed to provide financing (the
"Financing") to R&D Systems Company (the "Company") subject to the terms of
that certain Stock Purchase Agreement (the "Stock Purchase Agreement"), dated as
of the date hereof, by and among the Company, the stockholders of the Company
identified therein (the "Founders") and the investors identified therein (the
"Investors");

          WHEREAS, such Financing will significantly benefit the Company and
indirectly benefit the above-named Employee as a stockholder of the Company; and

          WHEREAS, this Agreement is a condition to the Stock Purchase
Agreement.

          NOW THEREFORE, in consideration of the foregoing and the mutual
covenants and agreements hereinafter set forth, the parties hereto agree as
follows:

1.        Non-Disclosure Obligation.  I understand and agree that my
          -------------------------                                 
employment creates a relationship of confidence and trust between me and the
Company with respect to (a) all proprietary and confidential information of the
Company, and (b) the confidential information of others with which the Company
has a business relationship.  The information referred to in clauses (a) and (b)
of the preceding sentence is referred to in this Agreement, collectively, as
"Confidential Information." I will not at any time, whether during or after the
termination of employment, for any reason whatsoever (other than to promote and
advance the business of the Company), reveal to any person or entity (both
commercial and non-commercial) or use for any purpose other than the furtherance
of the Company's business interests any of the trade secrets or Confidential
Information, including, but not limited to, the Company's research and
development activities; marketing plans and strategies; pricing and costing
policies; customer and supplier lists; and business or financial information of
the Company so far as they have come or may come to my knowledge, except as may
be required in the ordinary course of performing my duties as an employee of the
Company.  This restriction shall not apply to: (i) information that may be
disclosed generally or is in the public domain through no fault of mine; (ii)
information received from a third party outside the Company that was disclosed
without a breach of any confidentiality obligation; or (iii) information that
may be required by law or an order of any court, agency or proceeding to be
disclosed; provided, that such disclosure is subject to all applicable
governmental or judicial protection available for like material and I agree to
provide the Company with prior notice of any such disclosure.  I shall keep
secret all matters of such nature entrusted to me and shall not use or disclose
any such information in any manner, except as may be required in the ordinary
course of performing my duties as an employee of the Company.

          2.        Assignment of Inventions.  I expressly understand and agree
                    ------------------------                                   
that any and all right or interest I have or obtain in any designs, trade
secrets, technical specifications, technical data, know-how and show-how,
internal reports and memoranda, marketing plans, inventions, concepts, ideas,
expressions, discoveries, improvements, copyrights, and patent or patent rights
conceived, devised, developed, reduced to practice, or which I otherwise have or
obtain during the 
<PAGE>
 
term of this Agreement which relate to the business of the Company or arise out
of my employment with the Company are expressly regarded as "works for hire"
(the "Inventions").

          I hereby assign to the Company the sole and exclusive right to such
Inventions.  I agree that I will promptly disclose to the Company any and all
such Inventions, and that, upon request of the Company, I will execute and
deliver any and all documents or instruments and take any other action which the
Company shall deem necessary to assign to and vest completely in the Company, to
perfect trademark, copyright and patent protection with respect to, or to
otherwise protect the Company's trade secrets and proprietary interest in such
Inventions.  The obligations of this Section shall continue beyond the
termination of my employment with respect to such Inventions conceived of or
made by me during the term of this Agreement.  The Company agrees to pay any and
all copyright, trademark and patent fees and expenses or other costs incurred by
me for any assistance rendered to the Company pursuant to this Section.

          My obligation to assign Inventions shall not apply to any invention
about which I can prove that: (i) it was developed entirely on my own time and
effort; (ii) no equipment, supplies, facilities, trade secrets or confidential
information of the Company was used in its development; (iii) it does not relate
to the business of the Company or to the Company's actual or anticipated
research and development; and (iv) it does not result from any work performed by
me for the Company.

          3.        Documents, records, etc.  All documents, records, apparatus,
                    -----------------------                                     
equipment and other physical property, whether or not pertaining to Confidential
Information, which are furnished to me by the Company or are produced by me in
connection with my employment will be and remain the sole property of the
Company.  I will return to the Company all such materials and property as and
when requested by the Company.  In any event, I will return all such materials
and property immediately upon termination of my employment for any reason.  I
will not take with me any such material or property or any copies thereof upon
such termination.

          4.        Restrictions on Corporate Opportunities.  During my
                    ---------------------------------------            
employment with the Company and for a period of one (1) year thereafter, I will
not pursue, engage in or have an interest in other business ventures or
opportunities which arise out of, are similar to or competitive with the
business of the Company.  In addition, I will be obligated to present any
computer software business or investment opportunity arising out of the
Company's operations to the Company, and the Company shall have the exclusive
right to pursue such business or investment opportunity.
 
          5.        Absence of Conflicting Agreements.  I understand the Company
                    ---------------------------------                           
does not desire to acquire from me any trade secrets, know-how or confidential
business information that I may have acquired from others.  I represent that I
am not bound by any agreement or any other existing or previous business
relationship which conflicts with or prevents the full performance of my duties
and obligations to the Company under this Agreement or otherwise during the
course of my employment.

          6.        No Employment Obligation.  I understand that this Agreement
                    ------------------------                                   
does not create an obligation on the part of the Company to continue my
employment with the Company.  I am employed as an employee "at will."

          7.        Remedies Upon Breach.  I agree that it would be difficult to
                    --------------------                                        
measure any damages caused to the Company which might result from any breach by
me of the promises set forth in this Agreement, and that, in any event, money
damages would be an inadequate remedy for any such breach.  Accordingly, I agree
that if I breach, or propose to breach, any portion of this Agreement, the
Company shall be entitled, in addition to all other remedies that it may have,
to an injunction or other appropriate equitable relief to restrain any such
breach without showing or proving any actual damage to the Company.
<PAGE>
 
          8.        Binding Effect.  This Agreement will be binding upon me and
                    --------------                                             
my heirs, executors, administrators and legal representatives and will inure to
the benefit of the Company, any subsidiary of the Company, and its and their
respective successors and assigns.  My obligations under this Agreement shall
survive the termination of my relationship with the Company regardless of the
manner of such termination.

          9.        Enforceability.  If any portion or provision of this
                    --------------                                      
Agreement is to any extent declared illegal or unenforceable by a court of
competent jurisdiction, then the remainder of this Agreement, or the application
of such portion or provision in circumstances other than those as to which it is
so declared illegal or unenforceable, will not be affected thereby, and each
portion and provision of this Agreement shall be valid and enforceable to the
fullest extent permitted by law.  In the event that any provision of this
Agreement is determined by any court of competent jurisdiction to be
unenforceable by reason of excessive scope as to geographic, temporal or
functional coverage, such provision will be deemed to extend only over the
maximum geographic, temporal and functional scope as to which it may be
enforceable.


          10.       Entire Agreement.  This Agreement constitutes the entire
                    ----------------                                        
agreement between the Company and myself with respect to the subject matter
hereof, and supersedes all prior representations and agreements with respect to
such subject matter.  This Agreement may not be amended, modified or waived
except by a written instrument duly executed by the person against whom
enforcement of such amendment, modification or waiver is sought.  The failure of
any party to require the performance of any term or obligation of this
Agreement, or the waiver by any party of any breach of this Agreement, in any
particular case will not prevent any subsequent enforcement of such term or
obligation or to be deemed a waiver of any separate or subsequent breach.

          11.       Third Party Beneficiaries.  This Agreement is being entered
                    -------------------------                                  
into at the request of the Investors and such Investors are intended to be third
party beneficiaries hereunder with full power to enforce the terms hereof.

          12.       Notices.  Any notices, requests, demands and other
                    -------                                           
communications provided for by this Agreement will be sufficient if in writing
and delivered in person or sent by registered or certified mail, postage
prepaid, to me at the last address which I have filed in writing with the
Company or, in the case of any notice to the Company, at its main offices, to
the attention of its Chief Executive Officer.

          13. Governing Law.  This is a State of Colorado contract and shall be
              -------------                                                    
construed under and be governed in all respects by the laws of the State of
Colorado, without giving effect to its conflicts of law principles.

                                   ---------

                              R&D SYSTEMS COMPANY

                        1996 Stock Option and Grant Plan
                        --------------------------------

1.  PURPOSE

    This Stock Option and Grant Plan (the "Plan") is intended as a performance
incentive for officers, employees, directors, consultants and other key persons
of R&D Systems Company (the "Company") or its Subsidiaries (as hereinafter
defined) to enable the persons to whom options are granted (the "Optionees") or
to whom shares of common stock are granted (the "Grantees") to acquire or
increase a proprietary interest in the success of the Company. The Company
intends that this purpose will be effected by the granting of "incentive stock
options" ("Incentive Options") as defined in Section 422 of the Internal Revenue
Code of 1986, as amended (the "Code"), nonqualified stock options ("Nonqualified
Options") and outright grants of common stock under the Plan. The term
"Subsidiaries" includes any corporations in which stock possessing fifty percent
or more of the total combined voting power of all classes of stock is owned
directly or indirectly by the Company.

2.  OPTIONS TO BE GRANTED AND ADMINISTRATION

    (a)   Options granted under the Plan may be either Incentive Options or
Nonqualified Options, and shall be designated as such at the time of grant. To
the extent that any option intended to be an Incentive Option shall fail to
qualify as an "incentive stock option" under the Code, such option shall be
deemed to be a Nonqualified Option.

    (b)   The Plan shall be administered by a committee (the "Option Committee")
of not less than two directors of the Company appointed by the Board of
Directors of the Company (the "Board of Directors") each of whom is an "outside
director" within the meaning of Section 162(m) of the Code.


                                       1
<PAGE>
 
    (c)   Subject to the terms and conditions of the Plan, the Option Committee
shall have the power:
          
          (i)    To determine from time to time the options or stock to be
    granted to eligible persons under the Plan, to prescribe the terms and
    provisions (which need not be identical) of options or stock granted under
    the Plan to such persons and to approve the grant of options or stock, as
    the case may be;

          (ii)   To construe and interpret the Plan and grants thereunder and to
    establish, amend, and revoke rules and regulations for administration of the
    Plan. In this connection, the Option Committee may correct any defect or
    supply any omission, or reconcile any inconsistency in the Plan, in any
    option agreement, or in any related agreements, in the manner and to the
    extent it shall deem necessary or expedient to make the Plan fully
    effective. All decisions and determinations by the Option Committee in the
    exercise of this power shall be final and binding upon the Company, the
    Optionees and the Grantees; and

          (iii)  Generally, to exercise such powers and to perform such acts as
    are deemed necessary or expedient to promote the best interests of the
    Company with respect to the Plan.

3.  STOCK

    (a)   The stock granted under the Plan, or subject to the options granted
under the Plan, shall be shares of the Company's authorized but unissued common
stock, par value $.01 per share (the "Common Stock"). The total number of shares
that may be issued under the Plan shall not exceed an aggregate of 1,327,465
shares of Common Stock and the total number of shares of Common Stock that may
be issued to, and/or for which Options may be granted to, any one


                                       2
<PAGE>
 
individual during any one calendar year shall not exceed 700,000. Such number
shall be subject to adjustment as provided in Section 7 hereof.

    (b)   Whenever any outstanding option under the Plan expires, is cancelled
or is otherwise terminated (other than by exercise), the shares of Common Stock
allocable to the unexercised portion of such option may again be the subject of
options under the Plan or grants of Common Stock.

4.  ELIGIBILITY

    (a)   Incentive Options may be granted only to officers or other employees
of the Company or its Subsidiaries, including members of the Board of Directors
who are also employees of the Company or its Subsidiaries. Nonqualified Options
may be granted to officers or other employees of the Company or its
Subsidiaries, members of the Board of Directors and consultants and other key
persons who provide services to the Company or its Subsidiaries (regardless of
whether they are also employees). Grants of Common Stock may be made to any
officer, director, employee, consultant or other key person of the Company.

    (b)   No person shall be eligible to receive any Incentive Option under the
Plan if, at the date of grant, such person beneficially owns stock representing
in excess of 10% of the voting power of all outstanding capital stock of the
Company (a "Ten Percent Stockholder") unless notwithstanding anything in this
Plan to the contrary (i) the purchase price for the Common Stock subject to such
option is at least 110% of the fair market value of such stock at the time of
the grant and (ii) the option by its terms is not exercisable more than five
years from the date of grant thereof.

    (c)   Notwithstanding any other provision of the Plan, to the extent that
the aggregate fair market value of the stock with respect to which Incentive
Options are exercisable for the first

                                       3
<PAGE>
 
time by any individual during any calendar year (under all plans of the Company
and its parent and Subsidiaries) exceeds $100,000, the options attributable to
the excess over $100,000 shall be treated as Nonqualified Options under the
Plan. Such annual limitation shall be applied by taking Incentive Options into
account in the order in which they were granted.

5.  TERMS OF THE OPTION AGREEMENTS

    Subject to the terms and conditions of the Plan, each option agreement shall
contain such provisions as the Option Committee shall from time to time deem
appropriate. Option agreements need not be identical, but each option agreement
by appropriate language shall include the substance of all of the following
provisions:

    (a)   Expiration; Termination of Employment. Notwithstanding any other
          -------------------------------------
provision of the Plan or of any option agreement, each option shall expire on
the date specified in the option agreement, which date in the case of any
Incentive Option shall not be later than the tenth anniversary of the date on
which the option was granted; provided, however, that if such Incentive Option
is held by a Ten Percent Stockholder, the expiration date of such Incentive
Option shall not be later than five years from the date of grant thereof. If an
Optionee's employment or service as a director with the Company and its
Subsidiaries terminates for any reason, the Option Committee may in its
discretion provide, at any time, that any outstanding option granted to such
Optionee under the Plan shall be exercisable for three months following
termination of employment, subject to the expiration date of such option.

    (b)   Minimum Shares Exercisable. The minimum number of shares with respect
          --------------------------
to which an option may be exercised at any one time shall be fifty (50) shares,
or such lesser number as is subject to exercise under the option at the time,
provided that no fractional shares may be issued.


                                       4
<PAGE>
 
    (c)   Exercise. Each option shall be exercisable in such installments (which
          --------
need not be equal) and at such times as may be designated by the Option
Committee. To the extent not exercised, installments shall accumulate and be
exercisable, in whole or in part, at any time after becoming exercisable, but
not later than the date the option expires.

    (d)   Purchase Price. The purchase price per share of Common Stock subject
          --------------
to each option shall be determined by the Option Committee; provided, however,
that the purchase price per share of Common Stock subject to each Incentive
Option shall be not less than the fair market value of the Common Stock on the
date such Incentive Option is granted. For the purposes of the Plan, the fair
market value of the Common Stock shall be determined in good faith by the Option
Committee; provided, however, that (i) if the Common Stock is admitted to
quotation on the National Association of Securities Dealers Automated Quotation
System ("NASDAQ") on the date the option is granted, the fair market value shall
not be less than the average of the highest bid and lowest asked prices of the
Common Stock on NASDAQ reported for such date, or (ii) if the Common Stock is
admitted to trading on a national securities exchange or the NASDAQ National
Market System on the date the option is granted, the fair market value shall not
be less than the closing price reported for the Common Stock on such exchange or
system for such date or, if no sales were reported for such date, for the last
date preceding such date for which a sale was reported.

    (e)   Rights of Optionees. No Optionee shall be deemed for any purpose to be
          -------------------
the owner of any shares of Common Stock subject to any option unless and until
(i) the option shall have been exercised pursuant to the terms thereof, (ii) all
requirements under applicable law and regulations shall have been complied with
to the satisfaction of the Company, (iii) the Company shall have issued and
delivered the shares to the Optionee, and (iv) the Optionee's name shall 

                                       5
<PAGE>
 
have been entered as a stockholder of record on the books of the Company.
Thereupon, the Optionee shall have full voting, dividend and other ownership
rights with respect to such shares of Common Stock.

    (f)   Transfer. No option granted hereunder shall be transferable by the
          --------
Optionee other than by will or by the laws of descent and distribution, and such
option may be exercised during the Optionee's lifetime only by the Optionee, or
his or her guardian or legal representative.

5A. TERMS OF STOCK GRANT

    Subject to the terms and conditions of this Plan, the Option Committee may
grant (or sell at a purchase price determined by such committee) shares of
Common Stock to eligible participants under this Plan. Such grants or issuances
may be on such terms as the Option Committee may determine, including
restrictions on transfer, rights of first refusal and repurchase provisions
based upon continuing employment and/or the achievement of performance goals or
other conditions. In no event may Common Stock issued or granted under this Plan
(other than as a result of the exercise of Options issued under this Plan) be
transferred or sold within six months of the date of issuance thereof.

6.  METHOD OF EXERCISE; PAYMENT OF PURCHASE PRICE

    (a)   Any option granted under the Plan may be exercised by the Optionee in
whole or, subject to Section 5(b) hereof, in part by delivering to the Company
on any business day a written notice specifying the number of shares of Common
Stock the Optionee then desires to purchase (the "Notice"). As a condition
precedent to the exercise of any option (i) prior to the closing date of the
Company's first underwritten public offering of the Common Stock, on or prior to
the exercise date, the Optionee shall execute and deliver a Stockholders'
Agreement with substantially the terms attached hereto as Exhibit A, which may
                                                          ---------
be amended from time to time 

                                       6
<PAGE>
 
and (ii) the Optionee shall pay or make arrangements for the payment of all
taxes to be withheld, in accordance with Section 9 of the Plan.

    (b)   Payment for the shares of Common Stock purchased pursuant to the
exercise of an option shall be made either: (i) in cash, or by certified or bank
check or other payment acceptable to the Company, equal to the option exercise
price for the number of shares specified in the Notice (the "Total Option
Price"); (ii) if authorized by the applicable option agreement and if permitted
by law, by delivery of shares of Common Stock that the optionee may freely
transfer having a fair market value, determined by reference to the provisions
of Section 5(d) hereof, equal to or less than the Total Option Price, plus cash
in an amount equal to the excess, if any, of the Total Option Price over the
fair market value of such shares of Common Stock; or (iii) by the Optionee
delivering the Notice to the Company together with irrevocable instructions to a
broker to promptly deliver the Total Option Price to the Company in cash or by
other method of payment acceptable to the Company; provided, however, that the
Optionee and the broker shall comply with such procedures and enter into such
agreements of indemnity or other agreements as the Company shall prescribe as a
condition of payment under this clause (iii).

    (c)   The delivery of certificates representing shares of Common Stock to be
purchased pursuant to the exercise of an option will be contingent upon the
Company's receipt of the Total Option Price and of any written representations
from the Optionee required by the Option Committee, and the fulfillment of any
other requirements contained in the option agreement or applicable provisions of
law.


                                       7
<PAGE>
 
7.  ADJUSTMENT UPON CHANGES IN CAPITALIZATION

    (a)   If the shares of the Company's Common Stock as a whole are increased,
decreased, changed into or exchanged for a different number or kind of shares or
securities of the Company, whether through merger, consolidation,
reorganization, recapitalization, reclassification, stock dividend, stock split,
combination of shares, exchange of shares, change in corporate structure or the
like, an appropriate and proportionate adjustment shall be made in the number
and kind of shares subject to the Plan, and in the number, kind, and per share
exercise price of shares subject to unexercised options or portions thereof
granted prior to any such change. In the event of any such adjustment in an
outstanding option, the Optionee thereafter shall have the right to purchase the
number of shares under such option at the per share price, as so adjusted, which
the Optionee could purchase at the total purchase price applicable to the option
immediately prior to such adjustment.

    (b)   Adjustments under this Section 7 shall be determined by the Option
Committee and such determinations shall be conclusive. The Option Committee
shall have the discretion and power in any such event to determine and to make
effective provision for acceleration of the time or times at which any option or
portion thereof shall become exercisable. No fractional shares of Common Stock
shall be issued under the Plan on account of any adjustment specified above.

8.  EFFECT OF CERTAIN TRANSACTIONS

    In the case of (i) the dissolution or liquidation of the Company, (ii) a
reorganization, merger, consolidation or other business combination in which the
Company is acquired by another entity (other than a holding company formed by
the Company) or in which the Company is not the surviving entity, or (iii) the
sale of all or substantially all of the assets of the Company 

                                       8
<PAGE>
 
to another entity, the Plan and the options issued hereunder shall terminate
upon the effectiveness of any such transaction or event, unless provision is
made in connection with such transaction for the assumption of options
theretofore granted, or the substitution for such options of new options of the
successor entity or parent thereof, with appropriate adjustment as to the number
and kind of shares and the per share exercise price, as provided in Section 7.
In the event of such termination, all outstanding vested options shall be
exercisable for at least fifteen (15) days prior to the date of such termination
whether or not otherwise vested or exercisable during such period.

9.  TAX WITHHOLDING

    Each Optionee shall, no later than the exercise date of any option, pay to
the Company, or make arrangements satisfactory to the Option Committee regarding
payment of any Federal, state, or local taxes of any kind required by law to be
withheld with respect to such income. The Company and its Subsidiaries shall, to
the extent permitted by law, have the right to deduct any such taxes from any
payment of any kind otherwise due to the Optionee.

10. CONDITION TO GRANTS OF COMMON STOCK

    As a condition precedent to the grant of Common Stock to any Grantee under
the Plan prior to the closing date of the Company's first underwritten public
offering of the Common Stock, the Grantee shall execute and deliver a
Stockholders' Agreement with substantially the terms attached hereto as Exhibit
                                                                        -------
A, which may be amended from time to time. The Option Committee may also impose
- -
such other terms and conditions on the grant of any Common Stock under the Plan
as it may determine.

11. AMENDMENT OF THE PLAN

    The Board of Directors may discontinue the Plan or amend the Plan at any
time, and from time to time, subject to any required regulatory approval and the
limitation that, except as 

                                       9
<PAGE>
 
provided in Sections 7 and 8 hereof, no amendment shall be effective unless
approved by the stockholders of the Company in accordance with applicable law
and regulations at an annual or special meeting held within twelve months before
or after the date of adoption of such amendment, where such amendment will:

    (a)   increase the number of shares of Common Stock as to which options may
be granted under the Plan;

    (b)   change in substance Section 4 hereof relating to eligibility to
participate in the Plan;

    (c)   change the minimum option exercise price; or

    (d)   otherwise materially increase the benefits accruing to participants
under the Plan.

    Except as provided in Sections 7 and 8 hereof, rights and obligations under
any option granted before any amendment of the Plan shall not be altered or
impaired by such amendment, except with the consent of the Optionee.

12. NONEXCLUSIVITY OF THE PLAN

    Neither the adoption of the Plan by the Board of Directors nor the
submission of the Plan to the stockholders of the Company for approval shall be
construed as creating any limitations on the power of the Board of Directors to
adopt such other incentive arrangements as it may deem desirable, including,
without limitation, the granting of stock or stock options otherwise than under
the Plan, and such arrangements may be either applicable generally or only in
specific cases. Neither the Plan nor any option granted hereunder shall be
deemed to confer upon any employee any right to continued employment with the
Company or its Subsidiaries.

13. GOVERNMENT AND OTHER REGULATIONS; GOVERNING LAW

    (a)   The obligation of the Company to sell and deliver shares of Common
Stock with respect to options granted under the Plan shall be subject to all
applicable laws, rules and regulations, including all applicable federal and
state securities laws, and the obtaining of all such approvals by governmental
agencies as may be deemed necessary or appropriate by the Option Committee.

    (b)   The Plan shall be governed by Delaware law, except to the extent that
such law is preempted by federal law.

14. EFFECTIVE DATE OF PLAN; STOCKHOLDER APPROVAL

    The Plan shall become effective upon the date that it is approved by the
Board of Directors of the Company; provided, however, that the Plan shall be
subject to the approval of the Company's stockholders in accordance with
applicable laws and regulations at an annual or special meeting held within
twelve months of such effective date. No options granted under the Plan prior to
such stockholder approval may be exercised until such approval has been
obtained. No options may be granted under the Plan after the tenth anniversary
of the effective date of the Plan.

                               ESCROW AGREEMENT
                               ----------------


     This Agreement is made and entered into as of March 14, 1996 by and among

(collectively, the "Linn Entities") and Guy M. Lammle, Rita L. Lammle, Amy

     WHEREAS, reference is made to the Stock Purchase Agreement, dated as of the

the Investors (the "Investment Agreement"), pursuant to which the Investors have
purchased 26,000 shares of Convertible Participating Preferred Stock, par value
$.01 per share, of the Company;

     WHEREAS, the Founders have agreed to indemnify the Investors against
certain losses resulting from breaches of the representations, obligations,
warranties and covenants made by the Company and the Founders in the Investment
Agreement;

     WHEREAS, under the Investment Agreement, the Founders and the Investors
have agreed that an aggregate amount of $4,900,000 will be deposited into
escrow, on the terms and conditions hereinafter provided, in an aggregate amount
equal to $4,900,000, to secure payment of such indemnification;

     WHEREAS, the Founders and the Investors acknowledge that the Founders have
not received, nor do they have control over, the funds deposited hereunder, and
that the Founders will not receive any control over such funds until certain
conditions set forth herein have been satisfied; and

     WHEREAS, Norwest Bank Colorado, N.A. is willing to serve as Escrow Agent
pursuant to the terms and conditions hereinafter set forth.

     NOW, THEREFORE, in consideration of the premises and agreements contained
herein, and other good and valuable consideration, the receipt and sufficiency
of which is hereby acknowledged by each party hereto, it is hereby agreed by and
among the Founders, the Investors and the Escrow Agent as follows:

     1.  Establishment of Escrow.  The Investors have herewith deposited with
         -----------------------                                             
the Escrow Agent, and the Escrow Agent acknowledges receipt of, the sum of Four
Million Nine Hundred Thousand Dollars ($4,900,000).  The consideration deposited
hereunder, and all interest and earnings thereon, shall be referred to as the
"Escrowed Funds."  The Escrowed Funds shall be held in escrow in the name of the
Escrow Agent or its nominee, subject to the terms and conditions set forth
herein.

<PAGE>
 
     2.  Investment of Escrowed Funds.  The Escrow Agent shall invest the
         ----------------------------                                    
Escrowed Funds in United States Treasury obligations with a remaining maturity
of less than one year and investment- grade commercial paper.  The Escrow Agent
shall not be responsible for any loss incurred upon any such investment made in
good faith.  All income and earnings of the Escrowed Funds shall be attributed
to the Founders.

     3.  Distribution of Earnings.  All amounts earned on the Escrowed Funds (by
         ------------------------                                               
way of interest, dividends or otherwise) shall not be distributed except as
provided in Section 6 and shall be held by the Escrow Agent under the terms of
this Agreement and shall be considered as part of the Escrowed Funds.

     4.  Claims Against Escrowed Funds.  At any time or times prior to the
         -----------------------------                                    
expiration of this Agreement, the Investors may make claims against the Escrowed
Funds, pursuant to the indemnification provisions set forth in Section 6 of the
Investment Agreement.  The Investors shall notify each of the Founders and the
Escrow Agent in writing prior to the expiration of this Agreement of each such
claim, including a brief description (based on information then available) of
the amount and nature of such claim.  If any of the Founders shall dispute such
claim, such Founder shall give written notice thereof to the Investors and to
the Escrow Agent within thirty (30) days after the date of notice of the
Investors' claim, in which case the Escrow Agent shall continue to hold the
Escrowed Funds in accordance with the terms of this Agreement; otherwise, such
claim shall be deemed to have been acknowledged to be payable out of the
Escrowed Funds in the full amount thereof and the Escrow Agent shall pay such
claim in immediately available funds to the Investors within three (3) business
days after expiration of said thirty-day period.  If the amount of the claim
exceeds the value of the Escrowed Funds, the Escrow Agent shall pay to the
Investors the entire Escrowed Funds and shall have no liability or
responsibility for any deficiency.

     5.  Disputed Claims.
         --------------- 

     (a) If any of the Founders shall dispute an indemnification claim of the
Investors by written notice as provided above, the Escrow Agent shall set aside
a portion of the Escrowed Funds sufficient to pay said claim in full, which
shall be based upon the full amount of such claim as set forth in the Investors
initial notice (the "Set Aside Amount").  In addition to the Set Aside Amount,
in the event the Investors notify the Escrow Agent in writing that it has made
out-of-pocket expenditures in connection with any such disputed claim, an amount
equal to such expenditures shall be set aside and added to and become a part of
the Set Aside Amount.

     (b) If the disputed indemnification claim has not been resolved or
compromised within sixty (60) days after any of the Founders gives notice of
dispute of the same, or in the event of a third-party claim or suit, within
fifteen (15) days after its resolution or compromise, said indemnification claim
shall be submitted to arbitration to be held in Boston, Massachusetts in
accordance with the rules and procedures of the American Arbitration
Association, and the decision of such arbitrators shall be final and conclusive
and judgment thereof may be entered in any court of law having jurisdiction,
including, without limitation, any Superior Court in the Commonwealth of
Massachusetts.  Notwithstanding the foregoing, in the

                                       2
<PAGE>
 
event the Escrow Agent seeks to become a party to any arbitration claim, the
venue for such claim shall be removed to Denver, Colorado. The fees and expenses
of the arbitrators shall be borne equally by the Investors on the one hand and
the Founders on the other, unless the arbitrators shall in their sole discretion
specify another allocation, and in such case such fees and expenses shall be
borne as so allocated. In no event shall the Escrow Agent be made a party to,
nor be responsible for any fee or expense of any party to, any arbitration
proceeding. The Escrow Agent shall make payment of such claim, as and to the
extent allowed, to the Investors out of the Set Aside Amount within three (3)
business days following said determination by the arbitrators.

     6.  Termination.  This Agreement shall terminate on the earlier to occur of
         -----------                                                            
(a)  the closing of an underwritten public offering pursuant to an effective
registration statement under the Securities Act of 1933, as amended, covering
the offer and sale of Common Stock of the Company to the public at a per share
price of at least $20.00, appropriately adjusted for stock dividends, stock
splits and the like, and in which the proceeds received by the Company, net of
underwriting discounts and commissions, equal or exceed $30,000,000, or (b)
thirty (30) days after receipt by the Company of the audited financial
statements for the fiscal year ending December 31, 1996, together with an
audited statement of income and retained earnings of the Company for the fiscal
year then ended (such earlier date, the "Termination Date"), and the balance of
the Escrowed Funds (including any amounts earned on the Escrowed Funds, less any
taxes paid or accrued by the Escrow Agent on such earnings) shall be distributed
to the Founders in the ratio of five-eighths to the Linn Entities and three-
eighths to the Lammle Entities (the "Sharing Ratio"); provided that there are no
                                                      -------- ----             
indemnification claims outstanding on the Termination Date and provided further
                                                               ----------------
that in the event that Data Dynamics, Inc. v. R&D Systems, Inc. has not been
                       ----------------------------------------             
finally adjudicated as of such Termination Date (in which event appropriate
reserves for the estimated liabilities, losses and expenses arising from such
lawsuit shall remain in escrow pending final adjudication of such lawsuit (which
reserves will not, in any event exceed $650,000)). If there are indemnification
claims outstanding on the Termination Date, this Agreement shall continue in
effect until all indemnification claims the Investors have made pursuant to
Section 4 hereof on or prior to the Termination Date shall have been disposed
of.  As of the Termination Date, an amount of the Escrowed Funds adequate to
cover all disputed and undisputed claims made by the Investors pursuant to
Section 4 hereof will be held by the Escrow Agent, and the Escrow Agent shall
distribute on the Termination Date the balance, if any, of the Escrowed Funds to
the Founders in accordance with the Sharing Ratio.  At such time as all
remaining indemnification claims hereunder have been resolved and the Escrow
Agent has received a written notice executed in counterpart by the Investors and
each of the Founders to that effect and any amounts to be distributed to the
Investors in connection therewith have been so distributed, the Escrow Agent
shall distribute the remaining Escrowed Funds, if any, to the Founders in
accordance with the Sharing Ratio or as directed by each of the Founders.

     7.  Duties and Responsibilities of Escrow Agent.
         ------------------------------------------- 

     (a) The Founders and the Investors acknowledge and agree that the Escrow
Agent (i) shall not be responsible for any of the agreements referred to herein

involve any expense or liability unless it shall have been furnished with
acceptable indemnification; (iii) may rely on and shall be protected in acting
or refraining from acting upon any written notice, instruction, instrument,
statement, request or document furnished to it hereunder and believed by it to
be genuine and to have been signed or presented by the proper person, and shall
have no responsibility for determining the accuracy thereof, and (iv) may
consult counsel satisfactory to it, including house counsel, and the opinion of
such counsel shall be full and complete authorization and protection in respect
of any action taken, suffered or omitted by it hereunder in good faith and in
accordance with the opinion of such counsel.

     (b) Neither the Escrow Agent nor any of its directors, officers or
employees shall be liable to anyone for any action taken or omitted to be taken
by it or any of its directors, officers or employees hereunder except in the
case of gross negligence or wilful misconduct.  The Founders and the Investors,
jointly and severally, covenant and agree to indemnify the Escrow Agent and hold
it harmless without limitation from and against any loss, liability or expense
of any nature incurred by the Escrow Agent arising out of or in connection with
this Agreement or with the administration of its duties hereunder, including but
not limited to reasonable legal fees and other costs and expenses of defending
or preparing to defend against any claim or liability, unless such loss,
liability or expense shall be caused by the Escrow Agent's willful misconduct or
gross negligence.  In no event shall the Escrow Agent be liable for indirect,
special or consequential damages.

     (c) The Founders agree to assume any and all obligations imposed now or
hereafter by any applicable tax law with respect to the payment of Escrowed
Funds under this Agreement, and to indemnify and hold the Escrow Agent harmless
from and against any taxes, additions for late payment, interest, penalties and
other expenses, that may be assessed against the Escrow Agent on any such
payment or other activities under this Agreement.  The Founders undertake to
instruct the Escrow Agent in writing with respect to the Escrow Agent's
responsibility for withholding and other taxes, assessments or other
governmental charges, certifications and governmental reporting in connection
with its acting as Escrow Agent under this Agreement.  The Founders agree to
indemnify and hold the Escrow Agent harmless from any liability on account of
taxes, assessments or other governmental charges, including without limitation
the withholding or deduction or the failure to withhold or deduct same, and any
liability for failure to obtain proper certifications or to properly report to
governmental authorities, to which the Escrow Agent may be or become subject in
connection with or which arises out of this Agreement including costs and
expenses (including reasonable legal fees), interest and penalties.

     (d) Concurrently with the execution of this Agreement by the parties
hereto, the Investors will pay to the Escrow Agent by check, as compensation for
the services of the Escrow Agent hereunder, a fee in accordance with the
schedule attached hereto as Exhibit A.  The Founders shall be liable for out of
                            ---------                                          
pocket expenses of the Escrow Agent referred to in Exhibit A.
                                                   --------- 

     (e) The Escrow Agent may at any time resign as Escrow Agent hereunder by
giving at least thirty (30) days' prior written notice of resignation to the
Founders and the 

                                       4
<PAGE>
 
Investors. Prior to the effective date of the resignation as specified in such
notice, the Founders and the Investors will issue to the Escrow Agent a written
instruction authorizing redelivery of the Escrowed Funds to a bank or trust
company that they select. Such bank or trust company shall have capital, surplus
and undivided profits in excess of $50,000,000. If, however, the Founders and
the Investors shall fail to name such a successor escrow agent within twenty
(20) days after receipt of notice of resignation from the Escrow Agent, the
Escrow Agent may apply to a court of competent jurisdiction for appointment of a
successor escrow agent. The provisions of paragraph (b) and (c) of this Section
7 shall survive the termination of this Agreement.

     8.  Dispute Resolution.  It is understood and agreed that should any
         ------------------                                              
dispute arise with respect to the delivery, ownership, right of possession,
and/or disposition of the Escrowed Funds, or should any claim be made upon the
Escrowed Funds by a third party, the Escrow Agent, upon receipt of written
notice of such dispute or claim by the parties hereto or by a third party, is
authorized and directed to retain in its possession without liability to anyone,
all or any of the Escrowed Funds until such dispute shall have been settled
either by the mutual agreement of the parties involved or by the dispute
resolution procedure set forth in Section 5(b) hereof.  The Escrow Agent may,
but shall be under no duty whatsoever to, institute or defend any legal
proceedings which relate to the Escrowed Funds.

     9.  Force Majeure.  Neither the Founders nor the Investors nor the Escrow
         -------------

from acts beyond its control.  Such acts shall include but not be limited to
acts of God, strikes, lockouts, riots, acts of war, epidemics, governmental
regulations superimposed after the fact, fire, communication line failures,
power failures, earthquakes or other disasters.

     10.  Notices.  Any notice permitted or required hereunder shall be deemed

     This General Release is delivered in connection with that certain Stock
Purchase Agreement (the "Purchase Agreement") dated as of March 14, 1996.

releases and discharges the Company, its past, present and future officers,
directors, employees, agents, successors, predecessors, divisions, subsidiaries,
affiliates, business units, assigns, subrogees and attorneys (each a "Released
Party") of and from any and all commitments, indebtedness, suits, demands,
obligations and liabilities, contingent or otherwise, every kind and nature,
including claims and causes of action both in law and in equity, which the
undersigned and/or his heirs, executors, administrators or assigns ever had, now
has or, to the extent arising from or in connection with any act, omission or
state of facts taken or existing on or prior to the date hereof, may have after

has been informed that from time to time the Company has received indications of
interest from third parties regarding possible acquisitions, joint ventures, or
additional types of financing, including a possible initial public offering, for
the Company ("Financing Transactions"), and that the Company may, at any time,
enter into one or more Financing Transactions which could result in a valuation
for the capital stock of the Company that is significantly higher than the
present value, (w) he is a sophisticated investor accustomed to making
valuations of investments such as the capital stock of the Company and agrees
that, in making his decision to have his capital stock redeemed by the Company
as contemplated by the Purchase Agreement, he has relied upon his own valuation
of the capital stock held by him and not upon a valuation provided by the
Company, (x) he has had an opportunity to obtain all information from the
Company relevant to his decision to have his capital stock redeemed by the
Company as contemplated by the Purchase Agreement, (y) notwithstanding the
possibility of any future Financing Transactions and the undersigned's review of
all Company-related information which he has deemed to be relevant to his
redemption decision, the undersigned has made a decision to have his capital
stock redeemed, and (z) the execution and delivery of this General Release was a
condition to the investment by the Investors

in the Company which funded the redemption of the undersigned's capital stock
and was relied upon by the Investors. The undersigned hereby acknowledges that
it is entering into this General Release with the full understanding of the
possibility that the Company may enter into one or more Financing Transactions.

     This General Release shall be governed by and construed in accordance with
the internal laws of Delaware.

To the Investors Listed in Appendix A to the Stock Purchase Agreement dated as
of March 14, 1996

Ladies and Gentlemen:

         We have acted as special counsel to R&D Systems Company, a Delaware
corporation (the "Company") and the Lammle Parties (as defined below) in
connection with (i) the merger (the "Merger") of R&D Systems Company, a Colorado
corporation, with and into the Company, (ii) the negotiation, execution and
delivery of the Stock Purchase Agreement (the "Purchase Agreement") dated as of
March 14, 1996, by and among (a) the Company, (b) Roger H. Linn ("R. Linn"),
Lois J. Linn, Jennifer Linn Trust and Sara Linn Trust, (collectively, the "Linn
Parties"), (c) Guy M. Lammle ("G. Lammle"), Rita L. Lammle, Amy Lammle Trust,
Daina Lammle Trust and Lacey Lammle Trust (collectively, the "Lammle Parties")
(the "Linn Parties" and the "Lammle Parties" collectively referred to as the
"Stockholders"), and (d) the Investors named therein (the "Investors"); (iii)
the issuance and sale by the Company of 26,000 shares (the "Preferred Shares")
of its authorized but unissued Series A Convertible Participating Preferred
Stock, par value $.01 per share (the "Preferred Stock"), for a purchase price of
$1,000 per Preferred Share to the Investors; (iv) the redemption (the
"Redemption") by the Company of 5,000 shares of the Company's common stock, par
value $.01 per share (the "Common Stock"), held by the Linn Parties and 3,000
shares of the Company's Common Stock held by the Lammle Parties; (v) the payment
to employees and agents of the Company of an aggregate of $7,000,000 (before
applicable withholding) (the "MSUIP Payment") pursuant to the Management Stock
Unit Incentive Plan of the Company (the "MSUIP") and (vi) the issuance to G.
Lammle of 640,845 shares of the Company's Common Stock (the "Common Stock")
pursuant to the Stock Purchase and Restriction Agreement, dated March 14, 1996
between the Company and G. Lammle (the "Restricted Stock Agreement"). This
opinion is being delivered to you pursuant to Section 3.2 of the Purchase
Agreement. Capitalized terms used in this opinion, unless
<PAGE>

specifically defined herein, shall have the meanings assigned them in the
Purchase Agreement.

         For purposes of this opinion, we have examined copies of the following
documents:

         a.    an executed copy of the Purchase Agreement;
           
         b.    an executed copy of the Stockholders' Agreement;
           
         c.    an executed copy of the Escrow Agreement;
           
         d.    an executed copy of the Non-Competition Agreement, dated March
14, 1996, between the Company and G. Lammle (the "Lammle Non-Competition
Agreement");

         e.    an executed copy of the Non-Competition Agreement between the
Company and R. Linn, dated March 14, 1996 (the "Linn Non-Competition
Agreement");

         f.    an executed copy of the Redemption and Exchange Agreement, dated
March 14, 1996, among the Company, the Lammle Parties and the Linn Parties (the
"Redemption Agreement");

         g.    an executed copy of the Restricted Stock Agreement;

         h.    an executed copy of the Indemnification Agreement, dated March
14, 1996 between the Company and the Investors (the "Indemnification
Agreement").

         i.    the Certificate of Incorporation of the Company as filed with the
Secretary of State of Delaware on March 11, 1996; the Agreement and Plan of
Merger, dated as of March 12, 1996 by and between the Company and R&D Systems
Company, a Colorado corporation ("R&D Colorado"); the Articles of Merger of R&D
Colorado into the Company, dated as of March 12, 1996 and the Certificate of
Merger of R&D Colorado into the Company dated as of March 12, 1996
(collectively, the "Merger Documents");

         j.    the Company's Amended and Restated Certificate of Incorporation
certified to us by an officer of the Company as being in full force and effect
as of the date of this opinion;
<PAGE>
 
March 15, 1996
Page 3



         k.    the Bylaws of the Company, as amended to date, and certified to
us by an officer of the Company as being complete and in full force and effect
as of the date of this opinion;

         l.    the trust agreements for the Daina Lammle Trust dated July 2,
1984, Amy Lammle Trust dated July 2, 1984, and Lacey Lammle Trust dated October
16, 1985 (collectively the "Lammle Trusts"); and

         m.    records certified to us by an officer of the Company as
constituting all records of proceedings and actions of the Board of Directors
and Stockholders of the Company relating to the transactions contemplated by the
Purchase Agreement.

         We have also examined such other documents, corporate records, other
certificates, instruments and statements of government officials and corporate
officials and other representatives of the Company as we have deemed necessary
or appropriate for the purpose of this opinion. As to certain questions of fact
material to such opinion, we have relied upon certificates from officers or
other representatives of the Company.

         As used in this opinion, the expression "to our best knowledge" with
reference to matters of fact means that, after an examination of documents in
our files and documents made available to us by the Company and the Stockholders
and after inquiries of officers of the Company and the Stockholders and based on
the actual present knowledge of the Holland & Hart attorneys who have had
significant responsibility representing the Company during the course of our
representation of the Company with respect to this matter, we find no reason to
believe that the opinions expressed herein are factually incorrect; but beyond
that we have made no independent factual investigation for the purpose of
rendering this opinion.

         We are qualified to practice in the State of Colorado, and we do not
purport to be experts in, and do not express any opinion herein concerning any
law other than the laws of such jurisdiction, the General Corporation Law of the
State of Delaware and federal law of the United States.

         In rendering the opinions expressed herein, we have assumed, without
independent verification, but with your consent, that:
<PAGE>
 
March 15, 1996
Page 4




         1.    the signatures of persons signing all documents in connection
with which this opinion is rendered are genuine (other than those of each of the
Company and the Lammle Parties, as to which our opinion is rendered below);

         2.    all documents submitted to us as originals or duplicate originals
are authentic;

         3.    all documents submitted to us as copies, whether certified or
not, conform to authentic original documents; and

         4.    all parties to the documents reviewed by us (other than the
Company and the Lammle Parties as to which our opinion is rendered below) have
full power, authority and legal capacity to execute and deliver, and to perform
their obligations under, such documents, and all such documents have been duly
authorized by all necessary corporate or other action on the part of such
parties, have been duly executed by such parties, have been duly delivered by
such parties and constitute the legal, valid and binding agreement of such
parties, enforceable in accordance with their terms.

         Based on the foregoing and upon an examination of such questions of law
as we have considered necessary or appropriate, it is our opinion that:

         1.    The Company is a corporation duly incorporated, validly existing
and in good standing under the laws of the State of Delaware and has the
corporate power to conduct its business.

         2.    The Merger has become effective under the laws of the states of
Delaware and Colorado.

         3.    The Company has the corporate power and authority (a) to execute,
deliver and perform the (i) Purchase Agreement, including, without limitation,
the power to issue the Preferred Shares, (ii) the Stockholders' Agreement, (iii)
the Lammle and Linn Non-Competition Agreements, (iv) the Redemption Agreement
(collectively, the "Company Transaction Documents"), (v) the Restricted Stock
Agreement and (vi) the Indemnification Agreement and (b) to make the MSUIP
Payment.

         4.    The Lammle Trusts have the power and authority to execute,
deliver and perform the Purchase Agreement, the
<PAGE>
 
March 15, 1996
Page 5



Stockholders' Agreement, the Escrow Agreement and the
Redemption Agreement.

         5.    Each of the Company Transaction Documents, the Restricted Stock
Agreement and the Indemnification Agreement has been duly authorized, executed
and delivered by the Company. The Redemption Agreement constitutes the legal,
valid and binding agreement of the Company, enforceable against the Company in
accordance with its terms. We note that the Purchase Agreement and the
Stockholders' Agreement are governed by the laws of The Commonwealth of
Massachusetts, and the Restricted Stock Agreement is governed by the laws of the
State of Delaware. However, if the laws of the State of Colorado were determined
by a court of competent jurisdiction to govern the Purchase Agreement, the
Stockholders' Agreement and the Restricted Stock Agreement, each of the Purchase
Agreement, the Stockholders' Agreement and the Restricted Stock Agreement would
constitute the valid and binding obligation of the Company enforceable against
the Company in accordance with its terms. Our opinion is subject to the
qualification that enforceability may be limited by bankruptcy, insolvency,
fraudulent conveyance, reorganization, moratorium and other laws affecting or
limiting the enforcement of creditors' rights generally; and such enforceability
is subject to general principles of equity (regardless of whether such
enforceability is considered in a proceeding in equity or at law). Furthermore,
we express no opinion on the enforceability of Section 7.3 of the Purchase
Agreement, Sections 4.6 and 6.10 of the Stockholders' Agreement, Section 8.4 of
the Restricted Stock Agreement or the Lammle or Linn Non-Competition Agreements.

         6.    The Lammle Non-Competition Agreement and the Restricted Stock
Agreement have been executed and delivered by G. Lammle. Each of the Purchase
Agreement, the Stockholders' Agreement, the Escrow Agreement and the Redemption
Agreement has been duly authorized, executed and delivered by the Lammle
Parties. The Escrow Agreement and the Redemption Agreement each constitutes the
legal, valid and binding agreement of the Lammle Parties, enforceable against
the Lammle Parties in accordance with its terms. We note that the Purchase
Agreement, the Stockholders' Agreement and the Restricted Stock Agreement are
governed by the laws of The Commonwealth of Massachusetts. However, if the laws
of the State of Colorado were determined by a court of competent jurisdiction to
govern the Purchase
<PAGE>
 
March 15, 1996
Page 6



Agreement, the Stockholders' Agreement and the Restricted Stock Agreement, each
of the Purchase Agreement and the Stockholders' Agreement would constitute the
valid and binding obligation of the Lammle Parties, and the Restricted Stock
Agreement would constitute the valid and binding obligation of G. Lammle,
enforceable in accordance with their respective terms. Our opinion is subject to
the qualification that enforceability may be limited by bankruptcy, insolvency,
fraudulent conveyance, reorganization, moratorium and other laws affecting or
limiting the enforcement of creditors' rights generally; and such enforceability
is subject to general principles of equity (regardless of whether such
enforceability is considered in a proceeding in equity or at law). Furthermore,
we express no opinion on the enforceability of Section 7.3 of the Purchase
Agreement, Sections 4.6 and 6.10 of the Stockholders' Agreement, Section 14 of
the Escrow Agreement or the Lammle and Linn Non-Competition Agreements.

         7.    Neither the execution or delivery of the Company Transaction
Documents, nor the performance by the Company of its obligations under the
Company Transaction Documents (a) violates any provision of the Amended and
Restated Certificate of Incorporation or the Bylaws of the Company, or (b)
except as set forth on Schedule A attached to this opinion, results in the
breach, constitutes a default under or results in the creation or imposition of
any lien, charge or encumbrance on any property or assets of the Company under
any indenture, agreement or other instrument listed on Schedule 2.11 of the
Purchase Agreement, or (c) assuming the accuracy of the representations of the
Investors in Section 5 of the Purchase Agreement, violates any federal, State of
Colorado or Delaware General Corporation law which affects the Company.

         8.    Assuming the accuracy of the representations of the Investors in
Section 5 of the Purchase Agreement, no authorization, approval or other action
by or notice to or filing with any federal, State of Colorado or Delaware
governmental authority or regulatory body is required in connection with the
execution and delivery of the Company Transaction Documents by the Company or
the performance of its obligations thereunder, except for the filing of the
Merger Documents with the Secretaries of State of Colorado and Delaware; filings
contemplated by the Loan Agreement dated March 14, 1996 between the Company,
Fleet Bank of Massachusetts, The First National Bank of Boston and Other
<PAGE>
 
March 15, 1996
Page 7



Financial Institutions (the "Loan Agreement"); and filings pursuant to federal
and state securities laws.

         9.    The Amended and Restated Certificate of Incorporation has been
duly adopted by the Company, has been duly filed with the Secretary of State of
Delaware and has become effective under the laws of Delaware.

         10.   The stock certificates representing the Series A Convertible
Participating Preferred Stock (the "Series A Preferred Stock") purchased at the
Closing have been duly authorized, executed and delivered by the Company, such
Series A Preferred Stock has been validly issued and is outstanding, fully paid
and nonassessable, and there are no statutory, or to our best knowledge
contractual, preemptive rights of stockholders or rights of first refusal with
respect to the issuance of such Preferred Stock.

         11.   The Senior Redeemable Preferred Stock and Common Stock issuable
upon conversion of the Series A Preferred Stock has been duly authorized and
reserved for issuance by the Company, there are no statutory, or to our best
knowledge contractual, preemptive rights of stockholders or rights of first
refusal with respect to the issuance of such Senior Redeemable Preferred Stock
and Common Stock and the Senior Redeemable Preferred Stock and Common Stock to
be issued upon conversion of such Preferred Stock will upon such issuance be
validly issued, fully paid and nonassessable.

         12.   Assuming the accuracy of the representations of the Investors in
Section 5 of the Purchase Agreement, the sale and issuance of (a) the Series A
Preferred Stock under the Purchase Agreement and (b) the Company's Common Stock
under the Restricted Stock Agreement does not require registration under the
Securities Act of 1933, as amended.

         13.   Schedule B attached to this opinion correctly sets forth the
number of shares of each class of the Company's authorized capital stock and the
number of outstanding shares of each such class as of the Closing.

         14.   To our best knowledge, except as set forth on Schedule B, there
are no (a) outstanding shares of capital stock or securities convertible into or
exchangeable or exercisable for shares of the Company's capital stock, or (b)
outstanding options for the purchase of any such capital stock.

         term of this Agreement, and provided further that the Transferee shall
                                     -------- -------
         have entered into an enforceable written agreement consented to by

              In addition to and without limitation of the other

         Incorporation of the Company.

              Section 3.2.  Right of Last Refusal. In the event that any of the
              -----------   ---------------------
         Stockholders, including any of their Permitted Transferees, receives a
         bona fide offer to purchase all or any portion of the Shares held by

         "Offeror"), such Stockholder (a "Transferring Stockholder") may,
         subject to the restrictions in the last paragraph of Section 3.1 and
         the provisions of Section 3.3 hereof, Transfer such Shares pursuant to
         and in accordance with the following provisions of this Section 3.2:

                                       6
<PAGE>
 
                   (a)  Such Transferring Stockholder shall cause the
         Transaction Offer and all of the terms thereof to be reduced to writing
         and shall notify each Investor (enclosing a copy of the Transaction
         Offer) of its wish to accept the Transaction Offer and otherwise comply
         with the provisions of this Section 3.2 and, if applicable, Section 3.3
         (such notice, the "Offer Notice").

                   (b)  Each Investor shall have the right (the "Right of Last
         Refusal") to offer to purchase that number of Shares covered by the
         Transaction Offer as shall be equal to the product obtained by
         multiplying (i) the total number of Shares subject to the Transaction
         Offer by (ii) a fraction, the numerator of which is the total number of
         shares of Common Stock owned by such Investor on the date of the Offer
         Notice on an as converted basis (including any shares of Common Stock
         that may be received upon conversion of the Series A Convertible
         Preferred Stock), and the denominator of which is the total number of
         Shares of Common Stock then held by all Investors on the date of the
         Offer Notice on an as converted basis. (The number of Shares that each
         Investor or its transferee is entitled to purchase under this Section
         3.2 shall be referred to as its "Pro Rata Fraction"). Each Investor
         shall have the right to transfer its right to any Pro Rata Fraction or
         part thereof to any transferee. In the event an Investor does not wish
         to purchase or to transfer its right to purchase its Pro Rata Fraction,
         then any Investors who so elect shall have the right to offer to
         purchase, on a pro rata basis with any other Investors who so elect,
         any Pro Rata Fraction not purchased by an Investor or its transferee.
         Each Investor shall have the right to accept the Transaction Offer as
         to all or part of the Shares offered thereby within thirty (30) days
         after receipt of the Offer Notice. In the event that an Investor shall
         elect to purchase all or a part of the Shares covered by the
         Transaction Offer, such Investor shall individually communicate in
         writing such election to purchase to the Transferring Stockholder,
         which communication shall be delivered by hand or mailed to such
         Transferring Stockholder in accordance with Section 6.4 hereof and
         shall, when taken in conjunction with the Transaction Offer, be deemed
         to constitute a valid, legally binding and enforceable agreement for
         the sale and purchase of the Shares covered thereby to the extent of
         the number of Shares, if any, allocated to such Investor in accordance
         with the following paragraph. In the event that the price set forth in
         the Offer Notice is stated in consideration other than cash or cash
         equivalents, the Board of Directors of the Company may determine the
         fair market value of such consideration, reasonably and in good faith,
         and the Investors may exercise their Right of Last Refusal by payment
         of such fair market value in cash or cash equivalents. Notwithstanding
         anything contained herein to the contrary, an Investor within an
         Investor Group shall have the right to purchase any shares with respect
         to which another Investor within the same Investor Group elects not to
         exercise their Right of Last Refusal.

               Upon the expiration of thirty (30) days following receipt of
         the Offer Notice by all Investors, the number of Shares to be purchased
         by each Investor shall be determined as follows: (x) there shall first
         be allocated to each Investor a number of Shares equal to the lesser of
         (A) the number of Shares as to which such Investor accepted the
         Transaction Offer or (B) such Investor's Pro Rata Fraction, and (y) the
         balance, if any, not allocated under clause (x) above, shall be
         allocated to those Investors who accepted the Transaction Offer as to a
         number of Shares which exceeded their respective Pro Rata Fractions, in
         each case on a pro rata basis in proportion to the amount of such
         excess. The closing for any purchase of Shares to the Investors
         hereunder shall take place within thirty (30) days after the expiration
         of the first thirty (30) day period following the Investors' receipt of
         the Offer Notice at the place and on the date specified by a
         majority-in-interest of the Investors.

                       (c)  In the event that the Investors do not elect to
         exercise the Right of Last Refusal with respect to all of the Shares
         proposed to be sold, the Investors shall not be entitled to purchase
         any such Shares and the Transferring Stockholder may sell all such
         Shares proposed to be sold to the Offeror on the terms and conditions
         set forth in the Offer Notice, subject to the restrictions set forth in
         the last paragraph of Section 3.1 and the further provisions of Section
         3.3. If the Transferring Stockholder's transfer to an Offeror is not
         consummated in accordance with the terms of the Transaction Offer
         within the later of (i) ninety (90) days after the expiration of the
         Right of Last Refusal and the Co-Sale Option set forth in Section 3.3
         below, if applicable, and (ii) the satisfaction of all governmental
         approval or filing requirements, the Transaction Offer shall be deemed
         to lapse, and any Transfers of Shares pursuant to such Transaction
         Offer shall be deemed to be in violation of the provisions of this
         Agreement unless the Investors are once again afforded the Right of
         Last Refusal provided for herein with respect to such Transaction
         Offer.

         Section 3.3.  Co-Sale Option. In the event that any Transferring
         -----------   --------------
Stockholder receives a Transaction Offer from an Offeror, and the Right of Last
Refusal is not exercised, such Transferring Stockholder may Transfer such Shares
only pursuant to and in accordance with the following provisions of this Section
3.3:

                       (a)  Each of the Investors shall have the right to
         participate in the Transaction Offer on the terms and conditions herein
         stated. The class of Shares with which the Investors shall have the
         right to participate in the Transaction Offer shall be determined in
         accordance with the following: (a) if the Transferring Stockholder
         elects to Transfer Series B Convertible Preferred Stock then the
         Investors shall have the right to participate in the Transaction Offer
         with Series A Convertible Preferred Stock; (b) if the Transferring
         Stockholder elects to Transfer Senior Redeemable Stock or Junior


                                       8
<PAGE>
 
         Redeemable Stock then the Investors shall have the right to participate
         in the Transaction Offer with Senior Redeemable Stock; and (c) if the
         Transferring Stockholder elects to Transfer Common Stock then the
         Investors shall have the right to participate in the Transaction Offer
         with Common Stock. The right to participate shall be exercisable upon
         written notice (the "Acceptance Notice") to the Transferring
         Stockholder within the later of (i) thirty (30) days after delivery to
         it of the Offer Notice and (ii) ten (10) days after the Transferring
         Stockholder notifies the Investors that the Investors have not elected
         to exercise the Right of Last Refusal with respect to all of the Shares
         proposed to be sold (the "Co-Sale Option"). The Acceptance Notice shall
         indicate the maximum number of Shares such Investor wishes to sell
         including the number of Shares it would sell if one or more other
         Investors do not elect to participate in the sale on the terms and
         conditions stated in the Offer Notice, except that any Investor who
         holds Preferred Stock shall be permitted to sell to the relevant
         purchaser Shares of Common Stock acquired upon conversion thereof or,
         at its election, an option to acquire such Common Stock when it
         receives the same upon such conversion at the election of such Investor
         or as otherwise provided in the Charter with the same effect as if
         Common Stock were being conveyed.

                       (b)  Each of the Investors shall have the right to sell a
         portion of its Shares pursuant to the Transaction Offer which is equal
         to or less than the product obtained by multiplying (i) the total
         number of Shares subject to the Transaction Offer by (ii) a fraction,
         the numerator of which is the total number of shares of Common Stock
         owned by such Investor on the date of the Offer Notice on an as
         converted basis (including any Common Stock issuable upon exercise of
         the Series A Convertible Preferred Stock), and the denominator of which
         is the total number of shares of Common Stock then held by all
         Investors and Stockholders on the date of the Offer Notice on an as
         converted basis. To the extent one or more Investors elect not to sell,
         or fail to exercise their right to sell, the full amount of such Shares
         which they are entitled to sell pursuant to this Section 3.3, the other
         Investors' rights to sell Shares shall be increased proportionately and
         the other Investors shall have an additional five (5) days from the
         date upon which they are notified of such election or failure to
         exercise in which to increase the number of Shares to be sold by them
         hereunder.

                       (c)  Within ten (10) days after the date by which the
         Investors were first required to notify the Transferring Stockholder of
         their intent to participate, the Transferring Stockholder shall notify
         each participating Investor of the number of Shares held by such
         Investor that will be included in the sale and the date on which the
         Transaction Offer will be consummated, which shall be no later than the
         later of (i) thirty (30) days after the date by which the Investors
         were required to notify the Transferring Stockholder of their intent to
         participate and (ii) the satisfaction of any governmental approval or
         filing requirements, if any.

                           (d) Each of participating Investors may effect its
         participation in any Transaction Offer hereunder by delivery to the
         Offeror, or to the Transferring Stockholder for delivery to the
         Offeror, of one or more instruments or certificates, properly endorsed
         for transfer, representing the Shares it elects to sell therein. At the
         time of consummation of the Transaction Offer, the Offeror shall remit
         directly to each Investor that portion of the sale proceeds to which
         each Investor is entitled by reason of its participation therein (less
         any adjustments due to the conversion of any convertible securities or
         the exercise of any exercisable securities).

                           (e) In the event that the Transaction Offer is not
         consummated within the period required by subsection (c) hereof or the
         Offeror fails timely to remit to each Investor its portion of the sale
         proceeds, the Transaction Offer shall be deemed to lapse, and any
         Transfers of Shares pursuant to such Transaction Offer shall be deemed
         to be in violation of the provisions of this Agreement unless the
         Transferring Stockholder once again complies with the provisions of
         Section 3.2 and this Section 3.3 hereof with respect to such
         Transaction Offer.

         Section 3.4.      Drag-Along Obligations.
         -----------       ----------------------

                           (a)  In the event that two-thirds-in-interest of the
         Investors determine to sell or otherwise dispose of all or
         substantially all of the assets of the Company or all or substantially
         all of the capital stock of the Company owned by the Investors to any
         non-Affiliate(s) of the Company or any of the Investors, or to cause
         the Company to merge with or into or consolidate with any non-
         Affiliate(s) of the Company or any of the Investors (in each case, the
         "Buyer") in a bona fide negotiated transaction (a "Sale"), each of the
         Stockholders, including any of their respective Permitted Transferees
         (collectively, the "Non-Investor Stockholders"), shall be obligated to
         and shall upon the written request of two-thirds-in-interest of the
         Investors: (i) sell, transfer and deliver, or cause to be sold,
         transferred and delivered, to the Buyer, his, her or its Shares
         (including for this purpose all of such Non-Investor Stockholder's
         Shares that presently or as a result of any such transaction may be
         acquired upon the exercise of options (following the payment of the
         exercise price therefore)) on substantially the same terms applicable
         to the Investors (with appropriate adjustments to reflect the
         conversion of convertible securities, the redemption of redeemable
         securities and the exercise of exercisable securities as well as the
         relative preferences and priorities of the Preferred Stock); and (ii)
         execute and deliver such instruments of conveyance and transfer and
         take such other action, including voting such Shares in favor of any
         Sale proposed by the Investors and executing any purchase agreements,
         merger agreements, indemnity agreements, escrow agreements or related
         documents, as the Investors or the Buyer may reasonably require in
         order to carry out the terms and provisions of this Section 3.4.

                           (b) In the event of a Sale to a Buyer as contemplated
         in Section 3.4(a) above, each Founder shall in the event that the
         Investors do not exercise their "drag- along" rights in Section 3.4(a)
         above, have the right to require the Investors to include such
         Founder's Shares in the Sale on the same terms as the Investors' Shares
         (with appropriate adjustments to reflect the conversion of convertible
         securities, the redemption of redeemable securities and the exercise of
         exercisable securities as well as the relative priorities and
         preferences of the Preferred Stock and the terms of any options issued
         by the Company), which such right shall be exercisable by the delivery
         of written notice to the Company and each of the Investors at least
         twenty (20) days prior to the date proposed for the closing of the
         Sale.

                           (c) Not less than thirty (30) days prior to the date
         proposed for the closing of any Sale, the Investors shall give written
         notice to each Non-Investor Stockholder, setting forth in reasonable
         detail the name or names of the Buyer, the terms and conditions of the
         Sale, including the purchase price, and the proposed closing date. In
         furtherance of the provisions of this Section 3.4, each of the
         Non-Investor Stockholders hereby (i) irrevocably appoints TA
         Associates, Inc. as its agent and attorney-in-fact (the "Agent") (with
         full power of substitution) to execute all agreements, instruments and
         certificates and take all actions necessary or desirable to effectuate
         any Sale hereunder; and (ii) grants to the Agent a proxy (which shall
         be deemed to be coupled with an interest and irrevocable) to vote the
         Shares held by such Non-Investor Stockholder and exercise any consent
         rights applicable thereto in favor of any Sale hereunder; provided,
         however, that the Investors shall not exercise such powers-of-attorney
         or proxies with respect to any Non-Investor Stockholder unless such 
         Non-Investor Stockholders are in breach of their obligations under this
         Section 3.4.

         Section 3.5. Prohibited Transfers. If any Transfer is made or attempted
         -----------  --------------------
contrary to the provisions of this Agreement, such purported Transfer shall be
void ab initio; the Company, the Investors and the other Stockholders shall
have, in addition to any other legal or equitable remedies which they may have,
the right to enforce the provisions of this Agreement by actions for specific
performance (to the extent permitted by law); and the Company shall have the
right to refuse to recognize any Transferee as one of its stockholders for any
purpose. Without limitation to the foregoing, each of the Investors and
Stockholders further agrees that the provisions of Section 6.7 shall apply in
the event of any violation or threatened violation of this Agreement.

ARTICLE IV  REGISTRATION RIGHTS
- ----------  -------------------

         The Company's obligation to register shares of Common Stock under this
Article IV shall terminate seven (7) years following the closing by the Company
of its first underwritten public 

                                      11
<PAGE>
 
offering pursuant to a registration statement under the Securities Act (an
"IPO") or, with respect to shares held by particular Investors or the Founders
and commencing on the first anniversary of any IPO, whenever such shares can be
fully transferred under Rule 144(k) of the Securities Act.

         Section 4.1. Piggyback Registration Rights. If at any time or times
         -----------  -----------------------------
after the date hereof, the Company shall determine to register any shares of its
Common Stock or securities convertible into or exchangeable or exercisable for
shares of Common Stock under the Securities Act (whether in connection with a
public offering of securities by the Company (a "primary offering"), a public
offering of securities by stockholders (a "secondary offering"), or both, but
not in connection with a registration effected solely to implement an employee
benefit plan or a transaction to which Rule 145 or any other similar rule of the
Commission under the Securities Act is applicable or a registration effected
pursuant to Sections 4.2 or 4.3 hereof), the Company will promptly give written
notice thereof to the Investors and the Founders. In connection with any such
registration, if within thirty (30) days after their receipt of such notice any
Investor or Founder requests the inclusion in such registration of some or all
of the Common Stock owned by such Investor or Founder, or into which any Shares
held by such Investor or Founder are convertible or exchangeable (the
"Registrable Shares"), the Company will use its best efforts to effect the
registration under the Securities Act of all Registrable Shares which all such
Investors and Founders so request; provided, however, that in the case of an
                                   --------  -------
underwritten public offering, if the underwriter determines that a limitation on
the number of shares to be underwritten is required, and (i) if such
registration is the first registered offering of the Company's securities to the
public, the underwriter may (subject to the allocation priority set forth below)
exclude from such registration and underwriting some or all of the Registrable
Shares which would otherwise be underwritten pursuant to the notice described
herein, and (ii) if such registration is other than the first registered
offering of the sale of the Company's securities to the public, the underwriter
may (subject to the allocation priority set forth below) limit the number of
Registrable Shares to be included in the registration and underwriting to not
less than thirty percent (30%) of the securities included therein (based on
aggregate market values). The Company shall advise all Investors and Founders
promptly after such determination by the underwriter, and the number of shares
of Registrable Shares that may be included in the registration and underwriting
shall be allocated among all Investors and Founders in proportion, as nearly as
practicable, to their respective holdings of Registrable Shares. If the Company
includes in such registration any Registrable Shares to be offered by it, all
expenses of the registration and offering and the reasonable fees and expenses
of one independent counsel for all of the Investors as a group on the one hand,
and the Founders as a group on the other, shall be borne by the Company, except
that the Investors and the Founders shall bear underwriting and selling
commissions attributable to their Registrable Shares being registered and
transfer taxes on Shares being sold by such Investors and Founders.

         Section 4.2. Demand Registration Rights. If on any two (2) occasions
         -----------  --------------------------
(which occasions shall in no event be less than six months apart from each
other) after the earlier of (i) two (2) years after the date of this Agreement
or (ii) six (6) months after the closing of the Company's first public offering
pursuant to a registration statement under the Securities Act, holders of an
aggregate of at least 40% of the Registrable Shares shall notify the Company in
writing that it or they intend to offer or cause to be offered for public sale
all or any portion of its or their Registrable Shares, the Company will notify
all of the Investors and the Founders of its receipt of such notification from
such Investor(s) or Founder(s). If within thirty (30) days after their receipt
of such notice any Investor or Founder requests the inclusion of some or all of
the Registrable Shares owned by such Investor or Founder in such registration,
the Company will use its best efforts to cause such Registrable Shares so
requested (including the Registrable Shares held by the Investor(s) or
Founder(s) giving the initial notice of intent to register hereunder) to be
registered under the Securities Act in accordance with the terms of this Section
4.2; provided, however, that unless such registration becomes effective, the
     --------  -------
Investors and the Founders shall be entitled to require an additional
registration pursuant to this Section 4.2; and, provided further that if such
                                                -------- -------
registration is underwritten and the underwriter determines that a limitation on
the number of shares to be underwritten is required, the first shares to be
excluded from such registration should be any shares registered for the benefit
of the Company, and thereafter any shares which the Investors and the Founders
have requested to be registered shall be limited, to the extent necessary, based
upon their respective holdings of Registrable Shares.

         All expenses of such registrations and offerings and the reasonable
fees and expenses of one independent counsel for all of the Investors as a group
on the one hand, and the Founders as a group on the other, shall be borne by the
Company. The Company may postpone the filing of any registration statement
required hereunder for a reasonable period of time, not to exceed 180 days
during any twelve month period, if the Company determines in good faith that
such filing would require the disclosure of a material transaction or other
matter and the Company determines reasonably and in good faith that such
disclosure would have a material adverse effect on the Company or otherwise
would not be in the best interest of the Company. The Company shall not be
required to cause a registration statement requested pursuant to this Section
4.2 to become effective prior to 180 days following the effective date of a
Registration Statement initiated by the Company, if the request for registration
has been received by the Company subsequent to the giving of written notice by
the Company, made in good faith, to the Investors and the Founders to the effect
that the Company is commencing to prepare a Company-initiated Registration
Statement (other than a registration effected solely to implement an employee
benefit plan or a transaction to which Rule 145 or any other similar rule of the
Commission under the Securities Act is applicable); provided, however, that the
Company shall use its best efforts to achieve such effectiveness promptly
following such 180-day period if the request pursuant to this Section 4.2 has
been made prior to the expiration of such 180-day period. If so requested by any
Investor or Founder in connection with a registration under this paragraph, the

                                      13
<PAGE>
 
Company shall take such steps as are required to register the Investors' and the
Founders' Registrable Shares for sale on a delayed or continuous basis under
Rule 415, and also take such steps as are required to keep any registration
effective until all of the Investors' and the Founders' Registrable Shares
registered thereunder are sold. Notwithstanding the foregoing, the Company shall
have no obligation to keep any registration effective more than 120 days after
the initial date of effectiveness of such registration.

         Section 4.3. Form S-3. If the Company becomes eligible to use Form S-3
         -----------  --------
under the Securities Act or a comparable successor form, (a) the Company shall
use its best efforts to continue to qualify at all times for registration of its
capital stock on Form S-3 or such successor form, and (b) holders of an
aggregate of not less than twenty percent (20%) of the Registrable Shares shall
have the right to request and have effected one (1) registration of Shares on
Form S-3 or such successor form (such requests shall be in writing and shall
state the number of Shares to be disposed of and the intended method of
disposition of such Shares by such Investor(s) or Founder(s)) within any
consecutive twelve (12) month period. The Company will use its best efforts to
effect promptly the registration of all Shares on Form S-3 or such successor
form to the extent requested by such Investor(s) or Founder(s). If so requested
by such Investor(s) or Founder(s) in connection with a registration under this
Section 4.3, the Company shall take such steps as are required to register such
Investor's or Founder's Registrable Shares for sale on a delayed or continuous
basis under Rule 415, and to keep such registration effective until all of such
Investor's or Founder's Registrable Shares registered thereunder are sold.
Notwithstanding the foregoing, the Company shall have no obligation to keep any
registration effective more than 120 days after the initial date of
effectiveness of such registration. All expenses incurred in connection with a
registration requested pursuant to this Section 4.3 and the reasonable fees and
expenses of one independent counsel for all of the Investors as a group on the
one hand, and all of the Founders as a group on the other shall be borne by the
Company. The Company may postpone the filing of any Registration Statement
required hereunder for a reasonable period of time, not to exceed 180 days, if
the Company determines in good faith that such filing would require the
disclosure of a material transaction or other factor and the Company determines
reasonably and in good faith that such disclosure would have a material adverse
effect on the Company. The Company shall not be required to cause a Registration
Statement requested pursuant to this Section 4.3 to become effective prior to
180 days following the effective date of a Registration Statement initiated by
the Investors pursuant to Section 4.2 or by the Company, if the request for
registration has been received by the Company subsequent to the giving of
written notice by the Company, made in good faith, to the Investors and the
Founders to the effect that the Company is commencing to prepare a Company-
initiated Registration Statement (other than a registration effected solely to
implement an employee benefit plan or a transaction to which Rule 145 or any
other similar rule of the Commission under the Securities Act is applicable);
provided, however, that the Company shall use its best efforts to achieve such
- --------  -------
effectiveness 

                                      14
<PAGE>
 
promptly following such 180-day period if the request pursuant to this Section
4.3 has been made prior to the expiration of such 180-day period.

         Section 4.4. Further Obligations of the Company. Whenever, under the
         -----------  ----------------------------------
provisions of Sections 4.1, 4.2 or 4.3 of this Agreement, the Company is
required to register any Registrable Shares, it agrees that it shall also do the
following:

                       (a) Use its best efforts to diligently prepare and file
         with the Commission a registration statement and such amendments, post-
         effective amendments and supplements to said registration statement and
         the prospectus used in connection therewith as may be necessary to keep
         said registration statement effective and to comply with the provisions
         of the Securities Act with respect to the sale of securities covered by
         said registration statement for the period necessary to complete the
         proposed public offering;

                       (b) Furnish to each selling Investor or Founder such
         copies of each preliminary and final prospectus and such other
         documents as such Investor or Founder may reasonably request to
         facilitate the public offering of its Registrable Shares;

                       (c) Enter into any reasonable underwriting agreement
         required by the proposed underwriter for the selling Investors or
         Founders, if any;

                       (d) Use its commercially reasonable efforts to register
         or qualify the securities covered by said registration statement under
         the securities or "blue-sky" laws of such jurisdictions as any selling
         Investors or Founders may reasonably request, provided that the Company
         shall not be required to register or qualify the securities in any
         jurisdictions which require it to qualify to do business or subject
         itself to general service of process therein;

                       (e) Immediately notify each selling Investor or Founder,
         at any time when a prospectus relating to his Registrable Shares is
         required to be delivered under the Securities Act, of the happening of
         any event as a result of which such prospectus contains an untrue
         statement of a material fact or omits any material fact necessary to
         make the statements therein not misleading, and, at the request of any
         such selling Investor or Founder, prepare a supplement or amendment to
         such prospectus so that, as thereafter delivered to the purchasers of
         such Registrable Shares, such prospectus will not contain any untrue
         statement of a material fact or omit to state any material fact
         necessary to make the statements therein not misleading;

                                      15
<PAGE>
 
                      (f) Cause all such Registrable Shares to be listed on or
         included in each securities exchange or quotation system on which
         similar securities issued by the Company are then listed;

                      (g) Otherwise use its best efforts to comply with all
         applicable rules and regulations of the Commission and make generally
         available to its stockholders, in each case as soon as practicable, but
         not later than 30 days after the close of the period covered thereby an
         earnings statement of the Company which will satisfy the provisions of
         Section 11(a) of the Securities Act;

                      (h) The Company shall cooperate with each Investor and
         Founder and each underwriter participating in the disposition of
         Registrable Shares and their respective counsel in connection with any
         filings required to be made with the National Association of Securities
         Dealers, Inc.;

                      (i) The Company shall, during the period when the
         Prospectus is required to be delivered under the Securities Act,
         promptly file all documents required to be filed with the Commission
         pursuant to Sections 13(a), 13(c), 14 or 15(d) of the Exchange Act;

                      (j) The Company shall appoint a transfer agent and
         registrar for all Registrable Shares covered by a Registration
         Statement not later than the effective date of such Registration
         Statement; and

                      (k) In connection with an underwritten offering, the
         Company will participate, to the extent reasonably requested by the
         managing underwriter for the offering or the Investors or the
         Stockholders, in customary efforts to sell the securities under the
         offering, including without limitation, participating in "road shows."

         Section 4.5. Information about Holders. Each holder of Registrable
         -----------  -------------------------
Shares shall furnish to the Company such information regarding such holder
(including a statement as to whether such holder believes or has reason to
believe that the Company is in default under any of its agreements with such
holder) and the distribution proposed by such holder as the Company may request
in writing and as shall be required in connection with any registration,
qualification or compliance referred to in this Agreement.

         Section 4.6. Indemnification; Contribution.
         -----------  -----------------------------

                  (a) Incident to any registration statement referred to in this
Article IV, and subject to applicable law, the Company will indemnify and hold
harmless each underwriter, each 

                                      16
<PAGE>
 
Investor or Founder who offers or sells any such Registrable Shares in
connection with such registration statement (including its partners (including
partners of partners and stockholders of any such partners), and directors,
officers, employees and agents of any of them (a "Selling Stockholder"), and
each person who controls any of them within the meaning of Section 15 of the
Securities Act or Section 20 of the Securities Exchange Act of 1934 (the
"Exchange Act") (a "Controlling Person"), from and against any and all losses,
claims, damages, expenses and liabilities, joint or several (including any
investigation, legal and other expenses incurred in connection with, and any
amount paid in settlement of, any action, suit or proceeding or any claim
asserted), to which they, or any of them, may become subject under the
Securities Act, the Exchange Act or other federal or state statutory law or
regulation, at common law or otherwise, insofar as such losses, claims, damages
or liabilities arise out of or are based on (i) any untrue statement or alleged
untrue statement of a material fact contained in such registration statement
(including any related preliminary or definitive prospectus, or any amendment or
supplement to such registration statement or prospectus), (ii) any omission or
alleged omission to state in such document a material fact required to be stated
in it or necessary to make the statements in it not misleading, or (iii) any
violation by the Company of the Securities Act, any state securities or "blue
sky" laws or any rule or regulation thereunder in connection with such
registration; provided, however, that the Company will not be liable to the
extent that such loss, claim, damage, expense or liability arises from and is
based on an untrue statement or omission or alleged untrue statement or omission
made in reliance on and in conformity with information furnished in writing to
the Company by such underwriter, Selling Stockholder or Controlling Person
expressly for use in such registration statement. With respect to such untrue
statement or omission or alleged untrue statement or omission in the information
furnished in writing to the Company by such Selling Stockholder expressly for
use in such registration statement, such Selling Stockholder will indemnify and
hold harmless each underwriter, the Company (including its directors, officers,
employees and agents), each Founder, each other Investor (including its partners
(including partners of partners and stockholders of such partners) and
directors, officers, employees and agents of any of them) so registered, and
each person who controls any of them within the meaning of Section 15 of the
Securities Act or Section 20 of the Exchange Act, from and against any and all
losses, claims, damages, expenses and liabilities, joint or several, to which
they, or any of them, may become subject under the Securities Act, the Exchange
Act or other federal or state statutory law or regulation, at common law or
otherwise to the same extent provided in the immediately preceding sentence. In
no event, however, shall the liability of a Selling Stockholder for
indemnification under this Section 4.6(a) in its capacity as such (and not in
its capacity as an officer or director of the Company) exceed the lesser of (i)
that proportion of the total of such losses, claims, damages or liabilities
indemnified against equal to the proportion of the total securities sold under
such registration statement which is being sold by such Selling Stockholder or
(ii) the proceeds received by such Selling Stockholder from its sale of
Registrable Shares under such registration statement.

                                      17

                  (b) If the indemnification provided for in Section 4.6(a)
above for any reason is held by a court of competent jurisdiction to be
unavailable to an indemnified party in respect of any losses, claims, damages,
expenses or liabilities referred to therein, then each indemnifying party under
this Section 4.6, in lieu of indemnifying such indemnified party thereunder,
shall contribute to the amount paid or payable by such indemnified party as a
result of such losses, claims, damages, expenses or liabilities (i) in such
proportion as is appropriate to reflect the relative benefits received by the
Company, the other Selling Stockholders and the underwriters from the offering
of the Registrable Shares or (ii) if the allocation provided by clause (i) above
is not permitted by applicable law, in such proportion as is appropriate to
reflect not only the relative benefits referred to in clause (i) above but also
the relative fault of the Company, the other Selling Stockholders and the
underwriters in connection with the statements or omissions which resulted in
such losses, claims, damages, expenses or liabilities, as well as any other
relevant equitable considerations. The relative benefits received by the
Company, the Selling Stockholders and the underwriters shall be deemed to be in
the same respective proportions that the net proceeds from the offering (before
deducting expenses) received by the Company and the Selling Stockholders and the
underwriting discount received by the underwriters, in each case as set forth in
the table on the cover page of the applicable prospectus, bear to the aggregate
public offering price of the Registrable Shares. The relative fault of the
Company, the Selling Stockholders and the underwriters shall be determined by
reference to, among other things, whether the untrue or alleged untrue statement
of a material fact or the omission or alleged omission to state a material fact
relates to information supplied by the Company, the Selling Stockholders or the
underwriters and the parties' relative intent, knowledge, access to information
and opportunity to correct or prevent such statement or omission.

                  The Company, the Selling Stockholders, and the underwriters
agree that it would not be just and equitable if contribution pursuant to this
Section 4.6(b) were determined by pro rata or per capita allocation or by any
other method of allocation which does not take account of the equitable
considerations referred to in the immediately preceding paragraph. In no event,
however, shall a Selling Stockholder be required to contribute any amount under
this Section 4.6(b) in excess of the lesser of (i) that proportion of the total
of such losses, claims, damages or liabilities indemnified against equal to the
proportion of the total Registrable Shares sold under such registration
statement which are being sold by such Selling Stockholder or (ii) the proceeds
received by such Selling Stockholder from its sale of Registrable Shares under
such registration statement. No person found guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Securities Act)
shall be entitled to contribution from any person who was not found guilty of
such fraudulent misrepresentation.

                  (c) The amount paid by an indemnifying party or payable to an
indemnified party as a result of the losses, claims, damages and liabilities
referred to in this Section 4.6 shall be deemed to include, subject to the
limitations set forth above, any legal or other expenses

                                      18
<PAGE>
 
reasonably incurred by such indemnified party in connection with investigating
or defending any such action or claim, payable as the same are incurred. The
indemnification and contribution provided for in this Section 4.6 will remain in
full force and effect regardless of any investigation made by or on behalf of
the indemnified parties or any officer, director, employee, agent or controlling
person of the indemnified parties.

                  (d) Any person entitled to indemnification hereunder will (i)
give prompt written notice to the indemnifying party of any claim with respect
to which it seeks indemnification, but the failure to do so shall not relieve
the indemnifying party from any liability, except to the extent it is actually
prejudiced by the failure or delay in giving such notice, and (ii) unless in
such indemnified party's reasonable judgment a conflict of interest between such
indemnified and indemnifying parties may exist with respect to such claim,
permit such indemnifying party to assume the defense of such claim with counsel
reasonably satisfactory to the indemnified party. If such defense is assumed,
the indemnifying party will not be subject to any liability for any settlement
made by the indemnified party without its consent (but such consent will not be
unreasonably withheld). An indemnifying party with respect to such claim, unless
in the reasonable judgment of any indemnified party a conflict of interest may
exist between such indemnified party and any other of such indemnified parties
with respect to such claim.

         Section 4.7. Rule 144 Requirements. If the Company becomes subject to
         -----------  ---------------------
the reporting requirements of either Section 13 or 15(d) of the Exchange Act,
the Company will use its best efforts thereafter to file with the Commission
such information as is specified under either of said Sections for so long as
any of the Investors hold any Registrable Shares; and in such event, the Company
shall use its best efforts to take all action as may be required as a condition
to the availability of Rule 144 under the Securities Act (or any successor or
similar exemptive rules hereafter in effect). The Company shall furnish to any
holder of Registrable Shares upon request a written statement executed by the
Company as to the steps it has taken to comply with the current public
information requirement of Rule 144 or such successor rules.

         Section 4.8. Market Stand-Off. Each Investor and Founder agrees, if
         -----------  ----------------
requested by the Company and an underwriter of Registrable Shares of the
Company, not to sell or otherwise transfer or dispose of any Shares held by it
for such period, not to exceed 180 days following the effective date of any
registration statement (other than a registration effected solely to implement
an employee benefit plan or a transaction to which Rule 145 or any other similar
rule of the Commission under the Securities Act is applicable) of the Company
filed under the Securities Act as the Company or such underwriter shall specify
reasonably and in good faith.

statements and accounting practices), consisting in each case of three (3)
Directors, two (2) of whom shall have been designated by the Investors

such Investors, and in the case of the Founders, determined by the vote of a
majority-in-interest of the Founders).

         Section 5.5. No Waiver. Any failure by any of the parties hereto to
         -----------  ---------
fully exercise their rights to designate one or more Directors under this
Article V at any time shall not be construed to waive or limit their rights to

intended to be complete and exclusive statement of the agreement and
understanding of the parties hereto in respect of the subject matter contained

agreements contemplated hereby and thereby (including the exhibits hereto and
thereto) supersede all prior agreements and understandings between the parties
with respect to such subject matter.

         Section 6.9. Adjustments. All references to share prices and amounts
         -----------  -----------
herein shall be equitably adjusted to reflect stock splits, stock dividends,
recapitalizations and similar changes affecting the capital stock of the
Company.

         Section 6.10. Law Governing. This Agreement shall be construed and
         ------------  -------------
enforced in accordance with and governed by the laws of The Commonwealth of
Massachusetts (without giving effect to principles of conflicts of law), except
that any Delaware corporate law matters relating to the Company shall be
construed and enforced in accordance with and governed by the Delaware General
Corporation Law (without giving effect to principles of conflicts of law). Each
party also waives trial by jury in any action relating to this Agreement.

                    Stock set forth on Exhibits A and B opposite his, her or

                    pledges, security interests and rights of any kind or nature
                    whatsoever.

              b.    Authorization for and Validity of this Agreement.  The

                    accordance with its terms.

              c.    Breach or Default.  Neither the execution of this 
                    -----------------
                    Agreement nor the consummation of the transactions
                    contemplated by it will: 

                    (1)    result in the breach of any of the terms or
                           conditions of, or constitute a default under, any
                           mortgage, note, bond, indenture, contract, agreement,
                           license or other instrument or obligation of any kind

                    (2)    violate any order, writ, injunction or decree

5.     Lammle Entities Representations.  Each Lammle Entity severally represents
       -------------------------------                                          
       and warrants as follows:

              a.    The Lammle Entity is acquiring the Preferred Stock for its
                    own account, for investment, and not with a present view to
                    any "distribution" thereof within the meaning of the
                    Securities Act of 1933, as amended (the "Act").

              b.    The Lammle Entity understands that neither the Preferred
                    Stock to be issued and delivered to it pursuant to this
                    Agreement, nor any of the


                                       2
<PAGE>
 
                securities that the Preferred Stock is convertible into, have
                been registered under the Act, and that it cannot dispose of any
                or all of the Preferred Stock or the securities issuable upon
                conversion thereof unless such securities are registered under
                the Act or exemptions from such registration are available. The
                Lammle Entity understands that each certificate representing the
                Preferred Stock will bear the following legend or one
                substantially similar thereto:

                The securities represented by this certificate have not been
                registered under the Securities Act of 1933 (the "Act"). These
                securities have been acquired for investment and not with a view
                to distribution or resale, and may not be sold, mortgaged,
                pledged, hypothecated or otherwise transferred without an
                effective registration statement for such securities under the
                Act or the availability of an exemption from such registration
                requirements.

          c.    The Lammle Entity is sufficiently knowledgeable and experienced
                in the making of venture capital investments so as to be able to
                evaluate the risks and merits of its investment in the
                Corporation, and is able to bear the economic risk of loss of
                its investment in the Corporation.

6.     Survival of Representations, Warranties and Covenants.  All
       -----------------------------------------------------      
       representations, warranties, covenants and agreements of the parties
       hereto contained in this Agreement shall survive the Closing and shall
       continue in full force and effect indefinitely thereafter, subject only
       to applicable statutes of limitations.

7.     Indemnification.  Each Stockholder severally hereby agrees to save, 
       ---------------  
       defend, indemnify and hold harmless the Corporation and its officers,
       directors, stockholders, partners, members, managers, employees, agents,
       representatives and affiliates (collectively, the "Corporation
       Affiliates") against any loss, liability, damage or expense (including
       reasonable legal fees and expenses), or any claim which if unsuccessful
       would result in any such loss, liability, damage or expense, suffered or
       incurred by the Corporation for or on account of or arising from or in
       connection with a breach of any representation, warranty, covenant or
       agreement of any Stockholder contained in this Agreement.

Progress Software Corporation (PSC) and the Value Added Reseller (VAR) listed
above agree as follows:

  1.  PSC hereby grants to VAR, and VAR hereby accepts from PSC, the right to
obtain PSC products on a non-exclusive basis and to market their products to
Customers within the Territory set forth above (or the United States if no
Territory is indicated).

          1.1  VAR or its Customers who make use of PSC products to implement or
enhance products they supply shall be free to market PSC products in connection
with the products they supply, in any manner and in any territory they choose
and without incurring any liabilities or obligations to PSC, provided, however,
that in PSC's judgment the products they supply constitute substantial value
added and VAR or its customers are not attempting solely to market PSC products
within such territory in violation of this Agreement.

          1.2  VAR agrees to train within 60 days of signing the Agreement and
maintain a sufficient number (minimum of (1) one) of capable technical and sales
personnel to carry out the obligations and responsibilities of VAR under this
Agreement.

          1.3  VAR agrees to actively market PSC's then current annual
maintenance plan to its Customers.

          1.4  VAR agrees to notify PSC of each Customer to which it ships PSC
products (including product designation, serial number and name and address)
within five working days of shipment of product to such customer.

  2.  Prices and discounts attached hereto, and payment and credit terms may be
changed by PSC, subject to the following conditions:

          2.1  If the change results in an increase in cost to VAR, then such
change shall become effective only upon 30 days prior written notice by PSC.

          2.2  If the change results in a decrease in cost to VAR, then PSC will
grant VAR credit for the difference in cost on all products purchased within 30
days prior to the effective date of the change and not yet resold by VAR on the
effective date of the decrease.

          2.3  Payment shall be made to PSC by VAR within 30 days of shipment,
provided VAR meets PSC's credit requirements.  Otherwise payment shall be made
in advance or on a C.O.D. basis.  Interest shall accrue on any delinquent
amounts owed by VAR for PSC products at the lesser of eighteen percent (18%) per
annum or the maximum rate permitted by applicable usury law.

  3.  Each order placed by VAR for products shall be deemed to incorporate all
of the terms and conditions of this Agreement and any terms and conditions of
such order which are in addition to or inconsistent with the terms of this
Agreement shall be deemed stricken from such order.

      PSC shall ship products ordered by VAR as soon as practical after
acceptance of VAR's order. Delivery of products shall be FOB PSC's offices, and
risk of loss shall pass to VAR upon delivery to the carrier. VAR shall pay all
transportation and handling charges, insurance costs and sales and use taxes.

  4.  Each product shall be delivered to VAR in a package which may contain one
or more system media, introductory media, manual and license agreement.  VAR
shall deliver each product to the Customer unopened (except for those products
which require that VAR first record an application program on the system media).

  Title to PSC products (including the manual, media and program contained
therein) shall remain with PSC.  VAR shall not, and shall require in any
contrasts with its Customers that such Customers shall not, copy or modify any
products, nor remove, alter, cover or obfuscate any copyright notices or other
proprietary rights notices placed or embedded by PSC on or in any part of the
products.  VAR shall not be responsible for any actions of its Customers made in
violation of this Agreement or VAR's agreements without VAR's knowledge. VAR
shall be responsible for notifying PSC of such violations as they come to VAR's
attention.

  Because of the unique and proprietary nature of the products, it is understood
and agreed that PSC's remedies at law for a breach by VAR of its obligations
under this Section 4 will be inadequate and that PSC shall, in the event of any
such breach, be entitled to equitable relief (including without limitation
provisional and permanent injunctive relief and specific performance) in
addition to all other remedies provided under this Agreement or available to PSC
at law.
<PAGE>
 
  PSC through this Agreement shall acquire no rights to any application programs
developed or resold by VAR.

  PSC shall have the right to inspect and audit all the accounting, sales, and
customer service books and records of VAR to ensure compliance with the terms of
this Agreement.  Any such audit shall be conducted only by a Certified public
Accountant whose fee is paid by PSC and all audits shall be conducted during
regular business hours at VAR's offices and in such a manner as not to interfere
with VAR's normal business activities.

  5.  OTHER THAN THE LIMITED WARRANTY, IF ANY, ACCOMPANYING THE PRODUCT, PSC
MAKES NO WARRANTIES OR REPRESENTATIONS AS TO PERFORMANCE OF PSC PRODUCTS OR AS
TO SERVICE TO VAR OR TO ANY OTHER PERSON.  PSC RESERVES THE RIGHT TO CHANGE THE
WARRANTY AND SERVICE POLICY SET FORTH IN SUCH LIMITED WARRANTY, OR OTHERWISE AT
ANY TIME, WITHOUT FURTHER NOTICE AND WITHOUT LIABILITY TO VAR OR ANY OTHER
PERSON.

          5.1  TO THE EXTENT PERMITTED BY APPLICABLE LAW, ALL IMPLIED
WARRANTIES, INCLUDING BUT NOT LIMITED TO IMPLIED WARRANTIES OF MERCHANTABILITY,
FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT, ARE HEREBY EXCLUDED AND
THE LIABILITY OF PSC, IF ANY, FOR DAMAGES RELATED TO ANY PSC PRODUCTS SHALL BE
LIMITED TO THE ACTUAL AMOUNTS PAID BY VAR FOR SUCH PSC PRODUCT AND SHALL IN NO
EVENT INCLUDE INCIDENTAL OR CONSEQUENTIAL DAMAGES OF ANY KIND.

          5.2  VAR SHALL NOT MAKE OR PASS ON TO CUSTOMER ANY WARRANTY OR
REPRESENTATION ON BEHALF OF PSC OTHER THAN OR INCONSISTENT WITH THE LIMITED
WARRANTY.

          5.3  VAR agrees to take all actions reasonably specified by PSC in
writing from time to time in order to insure that the Limited Warranty is made
in compliance with all applicable laws.

  6.  VAR shall bear primary responsibility for developing applications or for
assisting Customers in developing applications with PSC products, and will
provide appropriate support to Customers in using PSC products and/or using
applications developed with PSC products.  PSC will provide  support to VAR from
PSC's offices by letter and telephone, and will provide support to VAR's
Customers in accordance with the applicable User Support Plan (if any) set forth
in the manual that accompanies each product.

  7.  For purposes of this Agreement, the term "PSC Trademarks" shall mean
those names and designations by which any of the products is known, and the name
"Progress Software Corporation" or "PSC".  VAR shall insure that none of the PSC
Trademarks ( or any variation thereof) appears in any portion of VAR's name or
any name under which VAR does business.

  8.  This Agreement may not be assigned by either party, except in connection
with a merger or sale of assets of such party which does not materially affect
its business activities nor its ability to carry out its obligations under this
Agreement.

  9.  This Agreement shall become effective upon the Effective Date (or upon the
date the Agreement is accepted by PSC if no Effective Date of Agreement is
indicated) set forth above and shall continue in force for three months.
Thereafter, it may be terminated upon thirty days written notice.

  Notwithstanding the foregoing, so long as any material breach of this
Agreement by VAR continues after thirty days written notice by PSC, PSC may
terminate this Agreement, including any orders issued by VAR, on written notice
to VAR.

  So long as any material breach under this Agreement by PSC continues after
thirty days written notice by VAR, VAR may terminate this Agreement on written
notice to PSC.

  In addition to any material breach of this Agreement, the application or
adjudication in bankruptcy of VAR, or the dissolution of VAR shall terminate
this Agreement.

  In the event this Agreement is terminated for any reason, VAR shall remain
responsible for safeguarding the trade secrets and proprietary rights of PSC,
and for payment to PSC for all products previously supplied.

  10. This Agreement shall be construed in accordance with the laws of the
Commonwealth of Massachusetts.

          include source code license fees charged by R&D or a Marketing
          Associate to an R&D customer; provided that such source code license
          fees are in addition to (and do not supersede) R&D's standard product
          license fee for an object code license.  If R&D or a Marketing
          Associate charge only the source code license fee, without the
          standard object code product license fee (pursuant to R&D's then-
          current price schedule), the special royalty provisions set forth in
          Sections 3(c) and 3(d) shall not apply and R&D or Marketing Associate
          shall purchase the required PSC product licenses pursuant to PSC's
          then-current price list less the discount set forth in Exhibit D."

3.   Notwithstanding anything to the contrary contained in the Agreement, the
     following terms and conditions shall apply to the distribution by R&D of
     the PSC products set forth in Section 3(e) hereof in connection with the
     R&D Trend Modules:

     a.  For the period commencing on March 1, 1996 and ending on January 1,
     1999, R&D shall have the right to distribute the PSC products identified in
     Section 3(e) hereof solely in connection with the deployment of the R&D
     Trend Software Modules in the United States and Canada subject to the terms
     and conditions of the Agreement and this Second Amendment.

     b.  R&D will, in its sole discretion, establish and maintain a product
     price schedule setting forth the product fees for the R&D Trend Modules.  A
     copy of the current price schedule is attached hereto as Exhibit B. R&D
     shall provide PSC with written notice of any updates to the above-mentioned
     price schedule.


                                      ***

<PAGE>
 
                                     ***



     e.   R&D shall have the right to deploy the following PSC product
     configuration for R&D Trend Modules customer for the fees set forth above:


 
     V7/V8        Enterprise server                Users equal to # of R&D Trend
                                                   Module users licensed
 
     V7/V8        Query/Results, Report Builder    16 users (combined)
 
     V7/V8        4GL Development System           1 user


     The above PSC product configuration is subject to modification upon written
     mutual agreement of the parties.  In the event PSC renames any of the
     above-listed PSC products in future releases, the above PSC product
     configuration shall be modified to reflect equivalent substitutions
     available under future releases.


                                     ***

<PAGE>
 
     g.   The special pricing provisions set forth in Section 3(c) above shall
     not apply to R&D existing customers (licensees of R&D Trend Software
     Modules prior to the effective date of this Second Amendment).  In the
     event any such customer requires additional PSC products or modifications
     to its current configurations or environments, such PSC product licenses or
     configuration modifications will be purchased from PSC pursuant to the then
     current PSC price list.  AP shall receive the discount set forth in Exhibit
     D hereto.

     h.   With respect to all licenses of the R&D Trend Software Modules which
     require additional PSC products or configurations different from Subsection
     3(e) above, R&D shall purchase such PSC product licenses and/or
     configurations (and optional PSC maintenance services) from the then-
     current PSC price list. R&D shall receive the discounts set forth in
     Exhibit D on the purchase of these PSC product licenses and/or
     configurations.  As of the effective date of this Second Amendment, all
     existing PSC Unlimited user licenses will remain unlimited unless PSC is
     notified in writing that R&D wishes otherwise.

4.   The royalty payment method described herein shall not be applicable if R&D
     discounts the PSC products at a percentage higher than the average discount
     applied to all components (hardware, software, professional services, etc.)
     of the total sale to the R&D customer.  Under such circumstances, R&D shall
     pay PSC the then-current list price for the  PSC products and maintenance
     services less the discounts set forth in Exhibit D hereto.

5.   The special pricing and distribution terms and conditions set forth herein
     apply only to the PSC product configurations described in Section 3(e),
     distributed by R&D or its Marketing Associates solely in conjunction with
     the R&D Trend Software Modules. R&D's deployment of PSC products in
     conjunction with any other PROGRESS-based application shall be subject to
     the standard terms and conditions set forth in the Agreement and PSC's
     then-current price list and standard AP discount schedule. R&D's  purchase
     of PSC product licenses for internal use shall be subject to PSC's then-
     current price list.

6.   PSC shall, at R&D's request, provide R&D master media for each of R&D's
     deployment operating system environments. Upon request, PSC shall provide
     one master media set for each additional environment or updates to the
     original environments at the then-current PSC media handling charges. R&D
     shall have the right to reproduce and distribute the PSC product
     configurations described in Section 3(e) for deployment to its R&D end-
     users in accordance with the terms and conditions of the Agreement and this
     Second Amendment. For each R&D end-user receiving PSC products, R&D shall,
     PRIOR TO SENDING ANY PSC PRODUCTS, enter into a license agreement executed
     by such end-user which incorporates by reference PSC's end-user license
     agreement (attached hereto as Exhibit E) and states that software delivered
     to the end-user includes PSC products subject to the terms and conditions
     of the attached PSC end-user license agreement. R&D shall maintain sole
     control over all copies of the master media and shall not release any such
     copies to any other party including but not limited to the R&D Marketing
     Associates.

7.   On a monthly basis, R&D shall provide the following reports to PSC:

<PAGE>
 
     (1) R&D Trend Software Modules Deployment Report including for each copy of
     the R&D Trend Modules licensed to an R&D customer directly by R&D or
     through an R&D Marketing Associate during the report month, the customer
     name, location, number of users, hardware configuration, PSC serial
     number(s), R&D Initial License Fee, R&D Annual License Fee and information
     about whether the products were distributed directly by R&D or through an
     R&D Marketing Associate;

     (2) Annual License Fee Report including for each existing R&D customer who
     has paid to R&D or an R&D Marketing Associate an Annual License Fee for a
     renewal release term during the report month, the customer name, location,
     PSC serial number(s) and the R&D Annual License Fee.

     Such required reports are due by the fifteenth (15th) day of each month
     following the month in which the R&D Trend Software Modules licenses are
     deployed and/or renewal Annual License Fee revenue is collected directly by
     R&D or one of its authorized Marketing Associates.

     Payment in full for PSC license royalties described in Section 3(c) above
     and the PSC royalties from the initial R&D Annual License Fees described in
     Section 3(d) above shall be due and payable within fifteen (15) business
     days of the due date for the R&D Trend Software Modules Deployment Report
     (regardless of whether or not R&D or an R&D Marketing Associate has
     collected the Initial License Fees or the initial Annual License Fees from
     the R&D customers).

     Payment in full for PSC royalties from renewal Annual License Fees (such
     royalties are described in Section 3(d) above) shall be due and payable
     within fifteen (15) business days of the due date for the Annual License
     Fee Report.  In the event R&D or an R&D Marketing Associate is unable to
     collect an Annual License Fee from an existing R&D customer for a renewal
     annual release term or an existing R&D customer elects not to purchase a
     renewal annual release term, R&D shall not be liable to PSC for payment of
     the PSC royalties for the Annual License Fee with respect to such
     customers; however, the PSC maintenance for such R&D customers will be
     considered to have lapsed and reinstatement will be subject to PSC's
     current policies concerning penalties and maintenance fees in effect at the
     time of reinstatement.

8.   R&D agrees that when providing PSC products to R&D Marketing Associates for
     further distribution to R&D end-users, R&D shall require such Marketing
     Associates to distribute PSC products solely in conjunction with the R&D
     Trend Software Modules.

9.   R&D shall have the right to distribute a reasonable number of PSC
     Application Development Environment product licenses to Marketing
     Associates without the requirement of licensing a PROGRESS-based
     application.  The term "reasonable" is defined to be TWO copies, but with
     mutual written agreement this number may be increased to more appropriately
     reflect unique businss opportunities. The license fees owed to PSC for the
     licenses described herein shall be subject to PSC's current price list less
     the product discount set forth in Exhibit D.  R&D shall require such
     Marketing Associate to use the aforementioned PSC product licenses solely
     to develop, enhance, and/or support R&D's applications for licensing to
     end-users and not use the copies for internal data processing requirements.
     For each of the aforementioned PSC

<PAGE>
 
     Application Development Environment product licenses, R&D shall report to
     PSC the following information: R&D Marketing Associate name, the location,
     hardware configuration, PSC serial numbers and designation as a Marketing
     Associate internal development and support license. Such information shall
     be reported to PSC on a monthly basis along with the above-mentioned
     license fees, in accordance with the reporting schedule and payment
     schedule set forth in Section 7. R&D shall have the right to distribute,
     free of charge, a single copy of a single PSC Deployment product to each
     Marketing Associate; provided that Marketing Associate's use of such
     product shall be solely for the purpose of demonstrating the R&D Trend
     Software Modules and shall, under no circumstances, be used for Marketing
     Associate's internal data processing activities. For each of the
     aforementioned PSC deployment licenses, R&D shall report to PSC the
     following information: R&D Marketing Associate name, the location, hardware
     configuration, PSC serial numbers, and designation as a Marketing Associate
     demonstration license. Such information shall be reported to PSC on a
     monthly basis in accordance with the reporting schedule set forth in
     Section 7 above.

10.  The special pricing terms and conditions specified above apply only to PSC
     products distributed by R&D or an R&D Marketing Associate for installation
     in the United States or Canada in accordance with the terms and conditions
     of the Agreement and this Second Amendment. R&D shall inform the R&D
     customers of the installation site restriction and require the Marketing
     Associates to do the same.

11.  R&D and PSC mutually agree that when sales conflict in the field takes
     place, R&D and PSC will work together to solve issues in an expeditious
     manner.


                                      ***


13.  Notwithstanding anything to the contrary set forth in the first paragraph
     of Section 9 of the Agreement, this Second Amendment shall continue in
     force until January 1, 1999 (unless any one or more of the reasons for
     termination listed in Section 9 of the Agreement occurs, i.e., uncured
     breach by either one of the parties, bankruptcy or involuntary dissolution
     of R&D).  Thereafter, provided R&D has not violated the terms

<PAGE>
 
     and conditions of the Agreement or this Second Amendment; and R&D and PSC
     have not negotiated a new pricing and distribution amendment, R&D shall
     purchase PSC products and services from PSC subject to the standard terms
     and conditions of the Agreement (prior to the Amendment and this Second
     Amendment) and the then current PSC price list and application partner
     discount schedule. Upon expiration or termination of this Second Amendment,
     R&D shall return to PSC all master media disks of the PSC products,
     including all copies thereof, in the possession of R&D.

14.  Notwithstanding anything to the contrary set forth in Section 8 of the
     Agreement, the special pricing and distribution terms and conditions set
     forth in this Second Amendment may not be assigned by R&D without the prior
     written consent of PSC, which shall not be unreasonably withheld.

15.  Except as modified herein, all provisions of the Agreement are hereby
     confirmed and in all respects this Second Amendment (including Exhibits A
     through D hereto) and the Agreement shall be read and construed together as
     if the provisions of this Second Amendment had been part of the Agreement.
     This Second Amendment completely supersedes the earlier Amendment.  No
     other modifications or additions are made to the Agreement.  Except as may
     be modified or amended by this Agreement, the terms and conditions of the
     Agreement shall remain in effect until termination of the Agreement.  In
     the event of conflict between the terms and conditions of the Agreement and
     this Second Amendment, the terms and conditions of this Second Amendment
     shall govern.

IN WITNESS WHEREOF, this Second Amendment has been executed under seal for and
on behalf of each of the parties hereto by their duly authorized representative
as of the date first set forth above.

CAUTION: OPENING THE MEDIA PACKAGE INDICATES YOUR UNDERSTANDING AND ACCEPTANCE 
OF THE FOLLOWING TERMS AND CONDITIONS. PLEASE CAREFULLY READ THESE TERMS AND 
CONDITIONS BEFORE OPENING THE SEALED PACKAGE. IF YOU DO NOT AGREE WITH THEM, 
PROMPTLY RETURN THE UNOPENED PACKAGE TO PROGRESS SOFTWARE CORPORATION OR THE 
DEALER FROM WHICH IT WAS ACQUIRED.
Subject to the following terms and conditions, Progress Software Corporation
(PSC) grants to you ("User") a non-exclusive license to use the enclosed
software Product(s) and related manuals ("Documentation").
1. SCOPE OF LICENSE.
1.1 This license allows User to install and use the Product solely on the single
computer model or on the nodes of a single network of specified computers for 
which the license was purchased, as set forth on the applicable license 
addendum, purchase order, or other documentation. If such documentation 
specifies a maximum number of simultaneous sessions, User agrees to limit usage 
in accordance with this restriction.
1.2 The Product may not be transferred, sold, assigned, or otherwise conveyed by
User to another party without PCS's prior written consent. Transfer of the 
Product to another computer or network may only be made following payment of the
then current Product Upgrade fees as specified in the applicable PSC price list.
1.3 A Product Update replaces part or all of a Product or Product Update 
previously licensed. Use of a Product Update terminates the license to use the 
Product or that part of the Product which the Product Update replaces and User 
shall destroy or return to PSC all copies of any prior Product or Product 
Update.
1.4 User may not grant sublicenses, leases, or other rights in the Product to 
others.
1.5 User may obtain rights to acquire Product Updates and other technical 
services under PSC's then current fees and terms.
1.6 This Agreement automatically terminates if User transfers possession of any 
copy of the Product or Product Update to another party.
2. PROGRESS SOFTWARE'S RIGHTS.
The Product and Documentation are proprietary products of PSC, or its 
licensor(s), and are protected by copyright law. By virtue of this Agreement, 
User acquires only the non-exclusive right to use the Product and does not 
acquire any rights of ownership in the Product or the media upon which it is 
embodied. PSC, or its licensor(s), shall at all times retain all rights, title 
and interest in the Product and the media.
3. NON-DISCLOSURE; COPIES; ALTERATIONS.
User agrees not to cause or permit the reverse engineering, disassembly, 
copying, or decompilation of the Product, except to reproduce machine-readable 
object code portions for back-up purposes and installation of new releases, 
under penalty of license termination but not exclusive of any other remedies. 
User may copy the Product for installation, back-up, or other purposes as 
described in the Documentation. User may not copy nor allow others to copy the 
Product or Product Update for any other purpose. User agrees not to remove any 
product identification, copyright notices, or other notices or proprietary 
restrictions from the Product. User may not copy nor allow others to copy any 
part of the manuals or other printed material provided with the Product or 
Product Update by any means, including data transmission or translation.
4. LIMITED WARRANTY.
PSC warrants that the materials of both the Product media and Documentation are 
not defective and that the software is properly recorded on the media. If either
the media (such as the diskettes, cartridges, and magnetic tapes) or the 
Documentation is physically defective, PSC will replace it free of charge during
the 90 day warranty period. User's remedy is limited to return of the media 
and/or Documentation to the supplier or to PSC for replacement. This Limited 
Warranty is in effect for claims made with 90 days from User's purchase of the 
Product.
PSC warrants that it has the right to license the Product(s). PSC will defend 
User against any claim based on an allegation that a Product infringes a U.S. 
patent or copyright, but only if PSC is notified promptly in writing of such 
claim and is given sole control of the defense thereof and all related 
settlement negotiations related thereto. Notwithstanding the foregoing, PSC 
shall not be liable to User for any claim arising from or based upon the 
alteration or modification of any of the Product(s). The Product has been tested
and the Documentation has been reviewed. However, except as specifically stated 
above, PSC MAKES NO WARRANTY OR REPRESENTATION, EITHER EXPRESSED OR IMPLIED, 
INCLUDING WARRANTIES OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE, 
WITH RESPECT TO THIS PRODUCT AND DOCUMENTATION. For example, PSC does not 
warrant that there are no discrepancies between the Product and the 
Documentation, nor that errors cannot arise during the use of the Product. THIS 
WARRANTY GIVES THE USER SPECIFIC LEGAL RIGHTS, AND MAY ALSO IMPLY OTHER RIGHTS 
WHICH VARY FROM STATE TO STATE. SOME STATES DO NOT ALLOW THE EXCLUSION OR 
LIMITATION OF IMPLIED WARRANTIES, AND DO NOT ALLOW A LIMITATION ON HOW LONG ANY
IMPLIED WARRANTY LASTS, SO THE ABOVE LIMITATIONS MAY NOT APPLY. No PSC employee,
supplier, or agent is authorized to make any modification or addition to this 
warranty.
5. LIMITATION OF LIABILITY.
TO THE EXTENT PERMITTED BY APPLICABLE LAW, THE LIABILITY OF PSC, IF ANY, FOR 
DAMAGES RELATING TO ANY PSC PRODUCTS SHALL BE LIMITED TO THE ACTUAL AMOUNTS PAID
BY USER FOR SUCH PSC PRODUCT AND SHALL IN NO EVENT INCLUDE INCIDENTAL OR 
CONSEQUENTIAL DAMAGES OF ANY KIND. SOME STATES DO NOT ALLOW THE EXCLUSION OF 
INCIDENTAL OR CONSEQUENTIAL DAMAGES, SO THE ABOVE LIMITATIONS MAY NOT APPLY.
6. EXPORT ADMINISTRATION.
User agrees to comply fully with all relevant regulations of the United States 
Department of Commerce and with the United States Export Administration Act to 
assure that the Product and Documentation are not exported or re-exported in 
violation of United States law. Further, User shall not directly or indirectly 
export or re-export any Products, Documentation, or the direct Product thereof 
without first obtaining PSC's written approval.

<PAGE>
 
                       Such Support Services shall be provided by VMARK at
                       VMARK's then prevailing prices, terms and conditions, as

14.     Infringement Indemnification
        ----------------------------

        14.1           VMARK shall defend any claim, suit or proceeding brought
                       against DISTRIBUTOR so far as it is based on a claim that
                       the use or transfer of Product(s) and related material
                       delivered hereunder constitutes an infringement of a
                       United States patent or copyright, so long as VMARK is
                       notified promptly in writing by DISTRIBUTOR as to any
                       such action and is given full authority, information and
                       assistance (at VMARKs expense) for the defense of any
                       such claim or proceeding. VMARK shall pay all damages and
                       costs awarded therein against DISTRIBUTOR but shall not
                       be responsible for any compromise made without its
                       consent. In the event of a final judgment which prohibits
                       DISTRIBUTOR or DISTRIBUTOR's customers continued use of
                       Product(s) by reason of infringement of a United States
                       patent or copyright, or if at any time VMARK is of the
                       opinion that Product(s) is likely to become the cause of
                       an action for infringement of a United States patent or
                       copyright, VMARK shall, at its sole option and at its
                       expense, either obtain the rights to continued use of
                       Product(s) or replace or modify Product(s) so that it is
                       no longer infringing.

        14.2           DISTRIBUTOR shall indemnify and hold harmless VMARK from
                       any loss, cost, or expense suffered or incurred in
                       connection with any claim, suit or proceeding brought
                       against VMARK so far as it is based on a claim that
                       Product(s) modified, altered or combined by DISTRIBUTOR
                       with any equipment, device or software not supplied by
                       VMARK hereunder constitutes such an infringement because
                       of such modification, alteration or combination.

15.     Use of VMARK's Name
        -------------------

        15.1           VMARK expressly prohibits any direct or indirect use,
                       reference to, or other employment of its name, trademarks
                       or trade names or of any name, trademark or trade name
                       exclusively licensed to VMARK, except in this Agreement
                       or as expressly authorized by VMARK in writing.

        15.2           All DISTRIBUTOR advertising and other promotional
                       material for Product(s) shall identify VMARK and will be
                       submitted to VMARK

                                       5
<PAGE>
 
                       for approval prior to release by DISTRIBUTOR. VMARK
                       acknowledges that its consent may not be unreasonably
                       withheld.

        15.3           VMARK hereby authorizes DISTRIBUTOR's use of the legend
                       VMARK AUTHORIZED DISTRIBUTOR. If utilized by DISTRIBUTOR,
                       said legend shall appear in conjunction with, and after,
                       DISTRIBUTOR's name and shall not be more prominent than
                       DISTRIBUTOR's name. DISTRIBUTOR shall submit to VMARK the
                       full particulars as to any requested use of the
                       authorized legend in any manner and shall not utilize the
                       same unless and until VMARK's written approval is
                       obtained.

        15.4           Upon termination of this Agreement, DISTRIBUTOR shall
                       discontinue the use of such legend in any manner and
                       thereafter shall not use, either directly or indirectly,
                       such legend or any similar legend, the use of which might
                       confuse or deceive the public and/or potential
                       DISTRIBUTOR customers.

        15.5           DISTRIBUTOR agrees that the names uniVerse and VMARK are
                       owned by VMARK, and DISTRIBUTOR shall upon request from
                       VMARK and at VMARK's cost and expense, assist VMARK in
                       taking appropriate steps to protect its rights in said
                       names.

        literature at no additional charge to DISTRIBUTOR. VMARK shall also
        provide one (1) set of system manuals with the initial version of
        Product(s) licensed by DISTRIBUTOR. DISTRIBUTOR may purchase additional
        manual(s) at VMARK's then prevailing prices for such manual(s).

18.     Excusable Delays
        ----------------

        VMARK shall not be liable for any loss, damage or penalty for delay in
        delivery or for failure to give notice of delay when such delay is due
        to causes beyond the reasonable control of VMARK, such as, but not
        limited to, acts of God, fire or explosions, war or civil disturbances,
        labor disturbances, delays in transportation or unreasonable delay in
        delivery by VMARK's vendors. The time for performance hereunder shall be
        extended by a period of time equal to the time lost because of any such
        delay.

        22.2      Termination of this Agreement shall not affect any of
                  DISTRIBUTOR's pretermination obligations hereunder and any
                  such term termination is without prejudice to the enforcement
                  of any undischarged obligations existing at the time of
                  termination.

        22.3      In the event of termination of this Agreement, DISTRIBUTOR

                  granted by DISTRIBUTOR to use Product(s).

        22.5      Sections 8 and 9 shall survive the termination or expiration

        24.4      The parties hereto agree that the terms and conditions
                  contained herein shall prevail notwithstanding any variations
                  on any orders submitted by DISTRIBUTOR.

        24.5      This Agreement shall be governed by, subject to and
                  construed in accordance with the laws of the Commonwealth of

                  parties except as may be required by law.

        24.7      DISTRIBUTOR understands that VMARK is subject to regulation by
                  agencies of the U.S. Government, including the U.S. Department
                  of Commerce, which prohibit export or diversion of VMARK
                  products to certain countries, and agrees it will not
                  knowingly assist or participate in any such diversion or other
                  violation of applicable U.S. laws and regulations. DISTRIBUTOR
                  warrants that it shall not license Product(s) in countries or

          annual basis, demonstrate sufficient business with VMARK to meet the
          following criteria:

          .  THRESHOLD SALES REVENUE for the elected COMMITMENT LEVEL

             following set out below:

                                                          THRESHOLD
              COMMITMENT  VANTAGE     QTRLY     LICENSE     SALES

  RHL          Gold        30%       $5,000       90%       $800K

______         Bronze      50%       $3,000       85%       $100K
 
               b.   As a VANTAGE PARTNER, DISTRIBUTOR's COMMITMENT LEVEL, and
                    accompanying criteria, shall be reviewed each year. If
                    DISTRIBUTOR fails to meet any of the above criteria
                    appropriate to the DISTRIBUTOR's COMMITMENT LEVEL, VMARK may
                    provide written notice, effective upon receipt by
                    DISTRIBUTOR, that DISTRIBUTOR shall be treated under the
                    terms and conditions of a different COMMITMENT LEVEL or
                    shall be required to select VANTAGE RESELLER terms and
                    conditions.

               c.   Upon each anniversary of the Effective Date of this
                    Agreement, DISTRIBUTOR may elect to change its VANTAGE
                    PARTNER COMMITMENT LEVEL or change to a VANTAGE RESELLER

                    change to a VANTAGE RESELLER status, the terms and
                    conditions and payments to VMARK for all Product licenses
                    sold prior to the effective date of change shall be those in

<PAGE>
 
                    VANTAGE PARTNER COMMITMENT LEVEL prior to the elected status
                    change.

        4.     Vantage Partner Payments
               ------------------------

               VMARK, at the beginning of each quarter, shall invoice
               DISTRIBUTOR for the greater of either;

               a.   The QUARTERLY MINIMUM appropriate to the COMMITMENT LEVEL as
                    elected by DISTRIBUTOR herein, or

               b.   The result of the following calculation:

                    Quarterly VMARK Charge = (VANTAGE PERCENTAGE x LICENSEE
                    PERCENTAGE x TOTAL MAINTENANCE CHARGE) divided by 4

                    EXAMPLE.

                    DISTRIBUTOR OMEGA, A VANTAGE PARTNER, HAS A COMMITMENT LEVEL
                    OF "GOLD". AS OF 12/13/94, DISTRIBUTOR OMEGA HAD SOLD 1,000
                    LICENSES WITH 10,000 TOTAL USERS; 5,000 OF THESE USERS HAVE
                    A LIST MAINTENANCE PRICE OF $56 PER USER (5,000 X $56 =
                    $280,000), AND 5,000 USERS HAVE A LIST MAINTENANCE PRICE OF
                    $51 PER USER (5,000 X $51= $255,000). THE TOTAL MAINTENANCE
                    CHARGE FOR DISTRIBUTOR OMEGA IS $535,000 (= $280,000 +
                    $255,000) FOR THE 10,000 USERS. THE QUARTERLY VMARK CHARGE
                    TO DISTRIBUTOR OMEGA FOR JANUARY 1, 1994, TO MARCH 31, 1994,
                    IS CALCULATED AS FOLLOWS: $36,112.50 = (.30 X.90 X $535,000)
                    divided by 4.
                    The first Quarterly VMARK Charge shall be invoiced upon the
                    effective Date of this Agreement and shall be prorated based
                    upon the number of days remaining within VMARK's business
                    quarter as a percentage of a ninety (90) day quarter.
                    Payments are due within thirty (30) days after invoice date.

        B.  VANTAGE RESELLER
            ----------------

Initial     As a VANTAGE RESELLER, for each Maintenance Agreement with the sub-
_______     licensee DISTRIBUTOR procures for VMARK for Product(s) licensed by
            DISTRIBUTOR, VMARK shall pay to DISTRIBUTOR a sales commission equal
            to the following percentages of the MAINTENANCE CHARGE, net of any
            discounts, e.g., for multi-year contracts, prepayments, etc., paid
            to VMARK:

                                       4
<PAGE>
 
                   .    1st year - twenty percent (20%)
                   .    2nd year - ten percent (10%)
                   .    3rd year - five percent (5%)

            To qualify for these payments, DISTRIBUTOR must procure the
            Maintenance Agreement with the sub-licensee at point of sale or
            within thirty (30) days of the date of license. Such commission
            payments shall be made by VMARK to DISTRIBUTOR each quarter for
            MAINTENANCE CHARGE payments made by DISTRIBUTOR's sub-licensee(s) to
            VMARK during the prior quarter. Payments will be made to DISTRIBUTOR
            within forty-five (45) days following the end of each quarter.

     United States Patent or copyright, DISTRIBUTOR or its Supplier shall, at
     its sole option and at its expense, either obtain the rights to continue
     use of product, replace or modify product so that it is no longer

                               Termite Amendment
                               -----------------

VMARK Software, Inc., ("VMARK") having its principal place of business at 50
Washington Street, Westboro, Massachusetts, 01581, and R & D Systems Company,
(CUSTOMER"), having its principal place of business at 5225 N. Academy Blvd,
Suite 100, Colorado Springs, CO 80918 agree that the terms and conditions herein
shall govern the licensing of the software listed on Schedule 1 ("SOFTWARE")
attached hereto at the prices set forth thereon and by this reference made a
part hereof.

Whereas, VMARK & Distributor have entered into a Distribution Agreement date
March 30,1995, such agreement is hereby amended as follows:

TERMITE is a product of Pixel innovations, Limited of Hemel Hempstead, Herts
Unit Kingdom, hereinafter referred to as "Pixel", with whom VMARK has a
worldwide re-seller and support agreement.

VMARK grants to DISTRIBUTOR the right to sell a limited function version of
TERMITE as part of DISTRIBUTOR's "Invision" product.  This limited function
version of TERMITE, hereinafter referred to as "PRODUCT," consists of:

     1.        The TERMITE Version 6 Windows executable program, with VT420 and
               WYSE 50 terminal emulation only.

     2.        'C' language, UNIX host file transfer routines. PRODUCT is not
               licensed for use with any other PIXEL developed host routines
               (i.e. PICK-based) or programs.

     3.        A VBX (Visual Basic Extension) that provides control of TERMITE
               executable program from another Windows program.

     4.        DISTRIBUTOR logos and markings in place of all PIXEL logos and
               markings.

     5.        All previously agreed enhancements as defined in attachment I
               (Intellex Letter dated 10 17-95, punch list)

PRODUCT does not include:

     1.        Any terminal emulations other than those specified above.

     2.        Any PICK host routines.

     3.        Any formal documentation. DISTRIBUTOR is responsible for
               supplying such documentation to its customers.

VMARK will provide DISTRIBUTOR with a "Master" diskette containing the PRODUCT
for the purpose of duplication and distribution as part of DISTRIBUTOR's
"Invision" product.  DISTRIBUTOR may only sell PRODUCT in conjunction with, and
for use with, "TREND", "SHIMS", and "GAP" applications.

VMARK will provide DISTRIBUTOR with electronic version of documentation and help
at no additional charge.

Upon execution of this agreement, DISTRIBUTOR agrees to place an advance order
for 1000 licenses of PRODUCT at a royalty of $35.00 per license.  In
consideration thereof, VMARK grants to DISTRIBUTOR at no additional charge an
internal use license for PRODUCT, to be used for development, sales and customer
support purposes.  This License will be limited to a total of 250 users.

After DISTRIBUTOR distributes the initial 1000 licenses of PRODUCT, DISTRIBUTOR
agrees to pay VMARK $35.00 per user for each license distributed thereafter.
<PAGE>
 
The royalty to VMARK for upgrades to any future versions of existing PRODUCT
will be $15.00 per user.

DISTRIBUTOR will report and pay to VMARK on a monthly basis the previous month's
sales of PRODUCT and PRODUCT upgrades.  VMARK reserves the right to audit
DISTRIBUTOR records at any time upon reasonable notice.

DISTRIBUTOR is responsible for providing all technical support for PRODUCT to
its customers.  VMARK shall provide DISTRIBUTOR with technical support for a
period of thirty (30) days following DISTRIBUTOR reporting sale of PRODUCT to a
customer.  Thereafter, DISTRIBUTOR may obtain technical support by purchasing
from VMARK Vantage Incident Packs for TERMITE.  Vantage Incident Packs for
TERMITE give DISTRIBUTOR telephone support 8 hours a day 5 days a week for a
period of 12 months.  An incident is defined as a single support issue and the
reasonable effort(s) needed to resolve it.  A single support issue is a problem
that cannot be broken down into subordinate problems.  If a problem consists of
subordinate problems, each problem is considered a separate incident.  Before
VMARK provides support for an incident, DISTRIBUTOR and VMARK's designated
support engineer(s) must agree on what the problem is and the parameters for an
acceptable solution.  An incident may require multiple telephone calls and off-
line research to resolve it.  A quarterly audit of incident usage will be
provided to DISTRIBUTOR upon request.

Vantage Incident Packs for TERMITE options available to DISTRIBUTOR are:

1.   10 Incidents for 12 months at $1,199.00, or
2.   25 Incidents for 12 months at $1,799.00 or
3.   50 Incidents for 12 months at $3,199.00.

The above Vantage Incident Packs for TERMITE options and prices are available as
of the date of this agreement and are subject to change in the future.

DISTRIBUTOR acknowledges that the PRODUCT and its source code are the property
of PIXEL.  All copyrights to the PRODUCT and its source code are owned by PIXEL.
The PRODUCT, its source code, routines associated programs, and documentation
remain the confidential property of PIXEL and can not be disclosed to anyone
without the prior written consent of PIXEL.

August, 1995  (the Effective Date), by and between R&D Systems Company, ("R&D"),
a Colorado corporation having its principal place of business at 5225 North
Academy Blvd., Suite 100, Colorado Springs, Colorado  80918 , and The
Distribution Team, Inc. ("DT"), a Texas Corporation having its principal
location at 4164 Austin Bluffs Parkway, Suite 338, Colorado Springs, Colorado,
80918.

R&D either owns or has the right to license the software products ("Software")
and their accompanying printed material ("Collateral Material") covered by this
Agreement;

R&D desires to grant and DT desires to accept a license to use the Software
subject to the terms and conditions contained herein;

In consideration of the above premises and the mutual covenants and conditions
contained herein, R&D and DT agree as follows:

1.  Recitals.
    -------- 

(a) R&D Systems Company. R&D is engaged in the business of developing,
    -------------------                                               
distributing and licensing distribution inventory management Software called
Trend, as well as selling the computer hardware on which to run said Software.
Among the Software modules developed and licensed by R&D is an on-line
Operations Guide ("Operations Guide").

(b) Intellex:  Intellex, a division of R&D, is engaged in the business of
    --------                                                             
developing strategic data warehouse applications for PC networks primarily to
complement the operational systems (like Trend) offered by other R&D divisions.
Included with Intellex's initial Software product offering, is a subsystem
Software product entitled  Manager's Handbook ("Handbook").  This subsystem
allows the user access to expert advice from ideas generated by industry
experts, and supplied to DT or the Intellex Division for inclusion in the
Handbook and which may be licensed along with the Operations Guide.

(c) The Distribution Team: The Distribution Team, hereinafter "DT" desires to
    -----------------------                                                  
obtain a copy of the Handbook code in order to develop a specific expert module
incorporating the expertise and advice of an industry expert Gordon Graham,
whose philosophies and teachings will be incorporated in a specific Handbook
called the "GGHandbook", or other handbooks at their sole discretion.

2.   Grant of License.  R&D grants to DT and DT accepts,  the following non-
     ----------------                                                      
transferable, non-exclusive rights:

(a)  A perpetual license to  market and sublicense the Handbook Software in
source or object code format as a standalone application outside of the R&D
and/or Intellex customer base, (unless modified in writing to the contrary); DT
acknowledges they are receiving a copy of the Handbook Software in both source
and object code format, and may sublicense source and object code to its'
customers. DT agrees to provide a list of its customers so licensed to R&D on a
quarterly calendar basis.

(b)  A $2,000 royalty  shall be paid to DT on every GGHandbook Software module
sold with each new Operations Guide customer licensed by R&D. For the purposes
of this Agreement, a new Operations Guide customer shall be defined as a
customer licensing Software from R&D wherein Operations Guide is licensed along
with other Software modules or products and is part of an overall Software
package licensed thereunder. R&D shall have no limitations on the prices for
such Software charged to its' customers, and R&D shall also have total
discretion as to whether such GGHandbook is sold as a separate module or
sold/bundled within its Software. If the SHIMS Software, owned by R&D and
marketed through the UDS division of R&D, uses Operations Guide concepts or
chooses to market the GGHandbook, the same $2,000 royalty will apply. Payments
will be made to DT on a quarterly basis and will be disbursed by R&D within
thirty (30) days of the close of a calendar quarter (March, June, September and
December). To qualify for payment, a sale must have been recognized as revenue
by R&D and R&D must have been paid in full by customer. R&D hereby commits to
including the GGHandbook in each license of its Operations Guide. The $2,000 per
license royalty may be fully paid up at any time by R&D via the execution of a
one-time $500,000 license payment to DT less any previously paid $2,000 royalty
payments accumulated up until execution of this one-time buy-out provision. Upon

                                       1
<PAGE> 
execution of the buy-out provision by R&D, DT shall be released from any support
or update obligations on the GGHandbook and R&D shall be granted a perpetual
license for the GGHandbook and all related Collateral Materials. Updated
Collateral materials and releases of the GGHandbook Software will become the
responsibility of R&D for its' own customers.

(c)  An option to market GGHandbook directly into R&D and/or Intellex customer
base.  Should  DT choose to exercise this option, they will:

     1)  Notify R&D in writing of their intention to exercise the option sixty
(60) days in advance of the date they wish to begin marketing;

     2)  Assume all responsibilities for billing and collections for sales of
Handbook into the R&D and/or Intellex customer base; and

     3)  Pay R&D a pre-negotiated royalty (in writing) on any sale into the
R&D and/or Intellex customer base (regardless of actual sale price by DT to
customer).

(d)  The understanding between the parties that, should a customer license
GGHandbook from DT and later become a customer of R&D/Intellex for an
operational system such as Trend or SHIMS or another like strategic system such
as Profit Workbench, DT will not receive the $2,000 royalty payment.
Furthermore, in such cases, the Intellex division of R&D will not pay its
royalty payment specified in section 2.c.4.

3.   Grant from DT to R&D: R&D shall be granted the right from the effective
     ----------------------                                                 
date of this Agreement until January 1, 1997, to purchase from DT  books and
videos known as the Gordon Graham books and videos owned by DT at a fifty
percent (50%) discount off current list price (Attached as Exhibit 1.) After
January 1, 1997, R&D's discount will be eighteen percent (18%) of the current
list price.

4.   Ownership of Software.  The Software, Handbook (including any images,
     ---------------------                                                
"applets", photographs, animations, video, audio, music and text incorporated
into the Software) is owned by R&D or its suppliers and DT shall have no
ownership interests therein.  The Software is protected by United States
copyright laws and international treaty provisions.  Therefore, DT must treat
the Handbook Software like any other copyrighted material (e.g., a book or
musical recording) except that they may either (a) make one (1) copy of the
                   ------                                                  
Handbook Software solely for backup or archival purposes, or (b) transfer the
Handbook Software to a single hard disk provided they keep the original solely
for backup or archival purposes.  DT agrees to take all reasonable steps to
protect the confidentiality of the Handbook Software and Collateral Material.

Likewise, the data stored in the Handbook database is owned by DT and is
protected by United States copyright laws and international treaty provisions.
R&D agrees to take all reasonable steps to protect the confidentiality of DT's
copyrighted material.

R&D acknowledges that DT shall have full ownership of the GGHandbook and R&D
shall have no rights of ownership therein.

5.   Technical & other Support Services from R&D.  R&D will provide DT with
     -------------------------------------------                           
unlimited access to the Intellex/R&D  Bulletin Board.  Should DT need technical
support other than through the Bulletin Board, R&D will make it available to DT
subject to the applicable fees and terms in place at the time such support is
requested by DT.  R&D will supply DT with contacts of all third party tool
vendors to enable DT to establish their own relationships with such vendors. R&D
will provide assistance to DT via reasonably requested and required resources,
which may be a combination of personnel, video and personal computer equipment.
Accounting and other administrative support services will be supplied at $250
per month or $3,000 per year and so long as R&D continues to receive the
preferred royalty rate of $2,000. The adequacy of such fees will be reviewed
annually by R&D's Board of Directors.  All costs of duplication and distribution
of GGHandbook Software and Collateral Materials will be the sole responsibility
of DT.
 
6.   Confidentiality.  DT agrees that they shall, during the term of this
     ---------------                                                     
Agreement, take all steps which are reasonable to safeguard the confidentiality
of, and proprietary rights to, the confidential information ("Confidential
Information") of the other party which may be disclosed as part of the execution
of this Agreement (including, but not limited to, product plans, designs,
business plans, technical specifications, research, customer or financial data)
and shall not, without prior written consent of R&D, (i) use such Confidential
Information for their own benefit or the benefit of any third party except for
purposes expressly provided for in this Agreement, or (ii) disclose such
Confidential Information to any third party; provided, however, that this
provision shall not be construed to restrict the disclosure of information which
(a) is publicly known at the time of its disclosure to DT, (b) is lawfully
received by DT from a third party not bound to a confidential relationship to
R&D, (c) was already known by DT prior to entering into this Agreement or (d) is
required by law to be disclosed.

                   DEFINITIONS AND ACCOUNTING AND OTHER TERMS

          Section 1.1.  Certain Defined Terms.  As used in this Agreement, the
          -----------   ---------------------                                 
following terms shall have the following meanings (such meanings to be equally

          "Adjusted Libor Rate" means, with respect to any Libor Loan to be made
          --------------------                                                  
by the Lenders for the Interest Period applicable to such Libor Loan, the
interest rate per annum determined by the Agent (fixed throughout such Interest
Period (subject to adjustments for the Libor Rate Reserve Percentage)) and
rounded upwards, if necessary, to the next 1/16 of 1%) which is equal to the
quotient of (i) the rate of interest determined by the Agent to be the average
of the interest rates per annum at which Dollar deposits in immediately
available funds are offered to each Reference Lender by first-class banks in the
London interbank market at approximately 11:00 a.m., London time, two Business

Reference Lender during such Interest Period under regulations of the Board of
Governors of the Federal Reserve System (or any successor), including without
limitation Regulation D or any other regulation dealing with maximum reserve

"Eurocurrency Liabilities", as that term may be defined from time to time by the
Board of Governors of the Federal Reserve System (or any successor) or are
otherwise imposed by the Board of Governors of the Federal Reserve System (or
any successor) and which in any other respect relate directly to the funding of
loans bearing interest at rates based on the interest rates at which Dollar
deposits in immediately available funds are offered to banks by first-class
banks in the London interbank market. If any Reference Lender fails to provide
its offered quotation to the Agent, the Adjusted Libor Rate shall be determined
on the basis of the offered quotation of the other Reference Lender. The
Adjusted Libor Rate shall be adjusted automatically on and as of the effective
date of any change in the Libor Rate Reserve Percentage.

          "Advance" and "Advances" means the funding by any Lender of all or a
           -------       --------

more of the securities having ordinary voting power for the election of

and policies of such Person whether by contract or otherwise, and the legal

the ratio of (a) total Indebtedness for Borrowed Money of the Borrower and its
Subsidiaries on a consolidated basis as of the last day of the most recently
ended fiscal quarter of the Borrower to (b) EBITDA for such fiscal quarter and
for the three immediately preceding Borrower fiscal quarters, (i) is less than
2.75:1.0, but greater than or equal to 2.25:1.0 and if and so long as no Event
of Default or Default exists and is continuing, the Applicable Margin shall,
subject to the last sentence of this definition, be two and one half percent
(2.50%), or (ii) is less than 2.25:1.0, but greater than or equal to 1.75:1.0
and if and so long as no Event of Default or Default exists and is continuing,

than or equal to 1.25:1.0 and if and so long as no Event of Default or Default
exists and is continuing , the Applicable Margin shall, subject to the last
sentence of this definition, be two percent (2.0%), or (iv) less than 1.25:1.0
and if and so long as no Event of Default or Default exists and is continuing,
the Applicable Margin shall, subject to the next-to-last sentence of this
definition, be one and three quarters percent (1.75%); provided further,
however, that if on any date the Borrower would be entitled to an Applicable
Margin other than 2.75% except for the fact that a Default exists, the
Applicable Margin shall not change until the first to occur of (a) such Default
becoming an Event of Default and (b) waiver or cure of such Default, at which
time the Applicable Margin shall be adjusted or remain the same in accordance
with the provisions of this definition preceding this further proviso.

          Any change in the Applicable Margin required pursuant to the foregoing
shall become effective on the fifth Business Day after the Agent receives the
Borrower's financial statement for the Borrower's fiscal quarter or year-end, as
the case may be, in question and only after, in the case of a decrease in the
Applicable Margin, receipt by the Agent of a written request for such rate
decrease from the Borrower; provided, however, that each of the above-referenced
interest rates shall remain in effect only so long as Borrower qualifies
therefor and provided further, however, that interest rate reductions shall
become final only on the basis of Borrower's annual audited financial statements
and in the event that such annual audited financial statements establish that
the Borrower was not entitled to a rate

                                       3

reduction which was previously granted, the Borrower shall, upon written
demand by the Agent repay to the Agent for the account of each Lender an amount
equal to the excess of interest at the rate which should have been charged based
on such annual audited financial statements and the rate actually charged on the
basis of Borrower's quarterly financial statement(s) (provided that in the event
of a dispute as to the appropriate fiscal quarter as to which any adjustment
should be allocated, the decision of the independent accountants of the Borrower
shall be made in accordance with GAAP and shall be binding upon the Agent, the
Lenders and the Borrower absent manifest error); and provided further, however,
that in the event that Borrower fails to provide any financial statement on a
timely basis in accordance with Section 5.3.3, any interest rate increase
                                -------------

accordance with the Agent's customary procedures as in effect from time to time.

          "Authorized Representative" means such senior personnel of the
           -------------------------

          Section 2.1.0.  The Revolving Credit Loans.  Each of the Lenders
          -------------   --------------------------                      
severally agrees, subject to the terms and conditions of this Agreement, to make
Advances of Revolving Credit Loans to the Borrower from time to time after
receipt by the Agent from time to time before the Revolving Credit Repayment
Date of, and at the times provided for in, a Request and an Interest Rate
Election from the Borrower in accordance with this Agreement, during the period
commencing on the Closing Date and ending on the Business Day immediately
preceding the Revolving Credit Repayment Date, in an aggregate principal amount
at any one time outstanding not to exceed the lesser of (i) such Lender's Pro
Rata Share of the Revolving Credit Loan Commitment less (ii) in each case, such
Lender's Pro Rata Share of the aggregate amount of any reductions of the
Revolving Credit Loan Commitment made pursuant to Section 2.6.4.
                                                  ------------- 

          Promptly after receipt of a Request and Interest Rate Election, Agent
shall notify each Lender by telephone, telex or telecopy of the proposed
borrowing.  Subject to the immediately preceding paragraph, each Lender agrees
that after its receipt of notification from Agent of Agent's receipt of a
Request and Interest Rate Election, such Lender shall send its Pro Rata Share
(or such portion thereof as may be necessary to provide Agent with such Pro Rata
Share in Dollars and in immediately available funds, without consideration or
use of any contra accounts of any Lender) of the requested Loan by wire transfer
to Agent so that Agent receives such Pro Rata Share in Dollars and in
immediately available funds not later than 12:00 P.M. (Boston, Massachusetts
time) on the first day of the Interest Period for any such requested Libor Loan
and on the Business Day for such Advance set forth in Borrower's Request for any
such requested Prime Rate Loan, and Agent shall advance funds to the Borrower by
depositing such funds in Borrower's account with the Agent upon Agent's receipt
of such Pro Rata Shares in the amount of the Pro Rata Shares of such Loan in
Agent's possession.  Agent's failure to receive any Pro Rata Share from a Lender
other than Fleet shall not excuse Agent from advancing Fleet's Pro Rata Share to
the Borrower.  Unless Agent shall have been notified by any Lender (which notice
may be telephonic if confirmed promptly in writing) prior to the first day of
the Interest Period in respect of any Loan which such Lender is obligated to
make under this Agreement, that such Lender does not intend to make available to
Agent such

                                      20
<PAGE>
 
Lender's Pro Rata Share of such Loan on such date, Agent may assume that such
Lender has made such amount available to Agent on such date and Agent in its
sole discretion may, but shall not be obligated to, make available to the
Borrower a corresponding amount on such date.  If such corresponding amount is
not in fact made available to Agent by such Lender, Agent shall be entitled to
recover such corresponding amount from such Lender promptly upon demand by Agent
together with interest thereon, for each day from such date until the date such
amount is paid to Agent, at the Federal Funds Rate for three (3) Business Days
and thereafter at the interest rate on the Loan in question.  If such Lender
does not pay such corresponding amount forthwith upon Agent's demand therefor,
Agent shall promptly notify the Borrower and the Borrower shall promptly pay
such corresponding amount to Agent. Nothing contained in this Section shall be
deemed to relieve any Lender from its obligation to fulfill its obligations
hereunder or to prejudice any rights which the Borrower may have against any
Lender as a result of any default by such Lender hereunder.

          Section 2.1.1.  Term Loans.  Each of the Lenders severally agrees,
          -------------   ----------                                        
subject to the terms and conditions of this Agreement, to make a Term Loan to
the Borrower in the amount of its respective Pro Rata Share of $25,000,000.
Borrower shall pay on the last day of each calendar quarter ending on or in
between the dates set forth below the amount of the Term Loans set forth
immediately opposite such dates below:

     Section 2.2.  Interest and Fees on the Loans.
     -----------   ------------------------------ 

          Section 2.2.1.  Interest.  Interest shall accrue and be paid currently
          -------------   --------                                              
on the Loans at Effective Prime or the Libor Rate for each of the Loans'
Interest Periods in accordance with the Borrower's Interest Rate Elections for
the Loans subject to and in accordance with the terms and conditions of this
Agreement and the Note(s); provided that if a Default or an Event of Default
exists and is continuing, no Interest Rate Election electing the Libor Rate
shall be effective and any Loan or portion thereof with respect to which any
such Interest Rate Election would otherwise have been effective shall bear
interest at Effective Prime plus, so long as an Event of Default exists and is
continuing, two percent (2.0%); (provided that the Borrower may elect one-month
Interest Periods while a Default exists, so long as no Event of Default exists)
all of the foregoing being applicable until such Default or Event of Default is
cured or waived and an Interest Rate Election electing the Libor Rate for such
Loan or portion thereof which is effective in accordance with this Agreement is
submitted to the Agent; and provided further that the Borrower shall submit
Interest Rate Elections so that on any date on which under Section 2.1.1 a
                                                           -------------  
regularly scheduled payment of principal of the Term Loans is to be made, at
least the amount of the Term Loans to be so repaid is bearing interest at
Effective Prime and/or such repayment date is an Interest Adjustment Date for
outstanding Libor Loans in such amount of the Term Loans.  The Borrower shall
pay such interest to the Agent for the pro rata account of each Lender in
arrears on the Loans (including without limitation Libor Loans) outstanding from
time to time after the Closing Date,  such payments to be made monthly on the
last Business Day of each calendar month of each year commencing March 31, 1996.
All provisions of each Note and any other agreements between the Borrower and
the Lenders are expressly subject to the condition that in no event, whether by
reason of acceleration of maturity of the Indebtedness evidenced by any Note or
otherwise, shall the amount paid or agreed to be paid to the Lenders which is
deemed interest under applicable law exceed the maximum permitted rate of
interest under applicable law (the "Maximum Permitted Rate"), which shall mean
the law in effect on the date of this Agreement, except that if there is a
change in such law which results in a higher Maximum Permitted Rate, then each
Note shall be governed by such amended law from and after its effective date.
In the event that fulfillment of any provision of any Note, or this Agreement or
any document, instrument or agreement providing security for any Note results in
the rate of interest charged under any Note being in excess of the Maximum
Permitted Rate, the obligation to be fulfilled shall automatically be reduced to
eliminate such excess.  If, notwithstanding the foregoing, any Lender receives
an amount which under applicable law would cause the interest rate under any
Note to exceed the Maximum Permitted

                                      22
<PAGE>
 
Rate, the portion thereof which would be excessive shall automatically be
deemed a prepayment of and be applied to the unpaid principal balance of such
Note to the extent of then outstanding Prime Rate Loans and not a payment of
interest and to the extent said excessive portion exceeds the outstanding
principal amount of Prime Rate Loans, said excessive portion shall be repaid to
the Borrower.

          Section 2.2.2.  Fees.  On the Closing Date the Borrower shall pay the
          -------------   ----                                                 
Facility Fee to the Agent for the accounts of Fleet and Bank of Boston in
accordance with their Pro Rata Shares.  In addition, on the last Business Day of
each March, June, September and December commencing March 31, 1996 and
continuing through the Revolving Credit Repayment Date, the Borrower shall pay
to the Agent for the pro rata account of each Lender, a fee in an amount equal
to .50% per annum of the amount, if any, by which the average actual daily
amount of the Revolving Credit Loan Commitment for the quarterly period just
ended (or in the case of the first such payment, the period from the Closing
Date to the date such payment is due) exceeds the average of the actual daily
outstanding principal balances of the Revolving Credit Loans (the "Unused
Fees").  In addition, the Borrower shall pay to the Agent for its own account
certain fees as specified in the Side Letter.

          Section 2.2.3.  Increased Costs - Capital.  If, after the date hereof,
          -------------   -------------------------                             
any Lender shall have reasonably determined that the adoption after the date
hereof of any applicable law, governmental rule, regulation or order regarding
capital adequacy of banks or bank holding companies, or any change therein, or
any change in the interpretation or administration thereof by any governmental
authority, central bank or comparable agency charged with the interpretation or
administration thereof, or compliance by such Lender with any policy, guideline,
directive or request regarding capital adequacy (whether or not having the force
of law and whether or not failure to comply therewith would be unlawful) of any
such authority, central bank or comparable agency, has or would have the effect
of reducing the rate of return on the capital of such Lender or such Lender's
holding company as a consequence of the obligations hereunder of such Lender to
a level below that which such Lender could have achieved but for such adoption,
change or compliance (taking into consideration the policies of such Lender with
respect to capital adequacy immediately before such adoption, change or
compliance and assuming that the capital of such Lender was fully utilized prior
to such adoption, change or compliance) by an amount reasonably deemed by such
Lender to be material, then such Lender shall notify the Agent and the Borrower
thereof and the Borrower shall pay to the Agent for the account of such Lender
from time to time as specified by such Lender such additional amounts (which
shall be deemed additional interest) as shall be sufficient to compensate such
Lender for such reduced return,

                                      23
<PAGE>
 
each such payment to be made by the Borrower within ten (10) Business Days
after each demand by such Lender, provided that the liability of the Borrower to
pay such costs shall only accrue with respect to costs accruing from and after
the 90th day prior to the date of each such demand.  A certificate in reasonable
detail of one of the officers of such Lender describing the event giving rise to
such reduction and setting forth the amount to be paid to such Lender hereunder
and a computation of such amount shall accompany any such demand and shall, in
the absence of manifest error, be presumed correct.  In determining such amount,
such Lender shall act reasonably and will use any reasonable averaging and
attribution methods which will, to the extent such increased costs or reductions
relate to such Lender's loans bearing interest at a rate based on the Adjusted
Libor Rate in general and are not attributable solely to the Loans hereunder, be
applied generally to such Lender's loans bearing interest at a rate based on the
Adjusted Libor Rate and such Lender's Libor Loans.  If the Borrower shall, as a
result of the requirements of this Section 2.2.3 above, be required to pay any
                                   -------------                              
Lender the additional costs referred to therein and the Borrower, in its sole
discretion, shall deem such additional amounts to be material, the Borrower
shall have the right to substitute another bank satisfactory to the Agent for
such Lender which has certified the additional costs to the Borrower, and the
Agent shall use reasonable efforts to assist the Borrower to locate such
substitute bank.  Any such substitution shall take place in accordance with
                                                                           
Section 9.11 and otherwise be on terms and conditions reasonably satisfactory to
- ------------                                                                    
the Agent, and until such time as such substitution shall be consummated, the
Borrower shall continue to pay such additional costs.  Upon any such
substitution, the Borrower shall pay or cause to be paid to the Lender that is
being replaced, all principal, interest (to the date of such substitution) and
other amounts owing hereunder to such Lender and such Lender will be released
from liability hereunder.

Section 2.3.  Notations.  At the time of (i) the making of each Loan evidenced 
- -----------   ---------                                             
by any Note, (ii) each change in the interest rate under any Note effected as a
result of an Interest Rate Election; and (iii) each payment or prepayment of any
Note, each Lender may enter upon its records an appropriate notation evidencing
(a) such Lender's Pro Rata Share of the Loans and (b) the interest rate and
Interest Adjustment Date applicable thereto or (c) such payment or prepayment
(voluntary or involuntary) of principal and (d) in the case of payments or
prepayments (voluntary or involuntary) of principal, the portion of the
applicable Loan which was paid or prepaid. No failure to make

                                      24
<PAGE>
 
any such notation shall affect the Borrower's unconditional obligations to
repay the Loans and all interest, fees and other sums due in connection with
this Agreement and/or any Note in full, nor shall any such failure, standing
alone, constitute grounds for disproving a payment of principal by the Borrower.
However, in the absence of manifest error, such notations and each Lender's
records containing such notations shall constitute presumptive evidence of the
facts stated therein, including, without limitation, the outstanding amount of
such Lender's Pro Rata Share of the Loans and all amounts due and owing to such
Lender at any time.  Any such notations and such Lender's records containing
such notations may be introduced in evidence in any judicial or administrative
proceeding relating to this Agreement, the Loans or any Note.

Section 2.4.  Computation of Interest.  Interest due under this Agreement and 
- -----------   -----------------------                          
any Note shall be computed on the basis of a year of 360 days for the actual
number of days elapsed.

Section 2.5.  Time of Payments and Prepayments in Immediately Available Funds.
- -----------   ---------------------------------------------------------------

          Section 2.5.1.  Time.  All payments and prepayments of principal,
          -------------   ----                                             
fees, interest and any other amounts owed from time to time under this Agreement
and/or under each Note shall be made to the Agent for the pro rata account of
each Lender at the address referred to in Section 9.6 in Dollars and in
                                          -----------                  
immediately available funds prior to 12:00 o'clock P.M. on the Business Day that
such payment is due, provided that the Borrower hereby authorizes and instructs
the Agent to charge against the Borrower's accounts with the Agent on each date
on which a payment is due hereunder and/or under any Note and on any subsequent
date if and to the extent any such payment is not made when due an amount up to
the principal, interest and fees due and payable to the Lenders, the Agent or
any Lender hereunder and/or under any Note and such charge shall be deemed
payment hereunder and under the Note(s) in question to the extent that
immediately available funds are then in such accounts.  The Agent shall use
reasonable efforts to give subsequent notice of any such charge to the Borrower
within a reasonable period, but the failure to give such notice shall not affect
the validity of any such charge.  To the extent that immediately available funds
are then in such accounts, the failure of the Agent to charge any such account
or the failure of the Agent to charge any such account prior to 12 o'clock P.M.
shall not be basis for an Event of Default under Section 6.1.1 and any amount
                                                 -------------               
due on the Loans on such date shall be deemed paid; provided that the Agent
shall have the right to charge any such account on any subsequent date for such
unpaid payment and an Event of Default shall exist if

                                      25
<PAGE>
 
sufficient immediately available funds are not in such accounts on the date
the Agent so charges such account after the expiration of any applicable cure
period.  In the event of any charge against the Borrower's accounts by the Agent
pursuant to the immediately preceding sentence, the Agent shall provide notice
to the Borrower of such charge within a reasonable time thereafter, but the
failure to provide such notice shall not in any way be a basis for any liability
of the Agent nor shall such failure adversely affect the validity and
effectiveness of any such action by the Agent.  Any such payment or prepayment
which is received by the Agent in Dollars and in immediately available funds
after 12 o'clock P.M. on a Business Day shall be deemed received for all
purposes of this Agreement on the next succeeding Business Day unless the
failure by Agent to receive such funds prior to 12 o'clock P.M. is due to
Agent's failure to charge the account of Borrower prior to 12 o'clock P.M.
except that solely for the purpose of determining whether a Default or Event of
Default has occurred under Section 6.1.1, any such payment or prepayment if
                           -------------                                   
received by the Agent prior to the close of the Agent's business on a Business
Day shall be deemed received on such Business Day.  All payments of principal,
interest, fees and any other amounts which are owing to any or all of the
Lenders or the Agent hereunder and/or under any of the Notes that are received
by the Agent in immediately available Dollars prior to 12:00 o'clock P.M. on any
Business Day shall, to the extent owing to the Lenders other than the Agent, be
sent by wire transfer by the Agent to any such other Lenders (in each case,
without deduction for any claim, defense or offset of any type) before 3:00
o'clock P.M. on the same Business Day.  Each such wire transfer shall be
addressed to each Lender in accordance with the wire instructions set forth in
Exhibit 1.9 hereto.  The amount of each payment wired by the Agent to each such
- -----------                                                                    
Lender shall be such amount as shall be necessary to provide such Lender with
its Pro Rata Share of such payment (without consideration or use of any contra
accounts of any Lender), or with such other amount as may be owing to such
Lender in accordance with this Agreement (in each case, without deduction for
any claim, defense or offset of any type).  Each such wire transfer shall be
sent by the Agent only after the Agent has received immediately available
Dollars from or on behalf of the Borrower and each such wire transfer shall
provide each Lender receiving same with immediately available Dollars on receipt
by such Lender.  Any such payments of immediately available Dollars received by
the Agent after 12:00 o'clock P.M. and before 3:00 o'clock P.M. on any Business
Day shall be forwarded in the same manner by the Agent to such Lender(s) as soon
as practicable on said Business Day, and if any such payments of immediately
available Dollars are received by the Agent after 3:00 o'clock P.M. on a
Business Day, the Agent shall so forward same to such

                                      26
<PAGE>
 
Lender(s) before 10:00 o'clock A.M. on the immediately succeeding Business
Day.  Any such wire transfer from the Agent to a Lender which is not received by
such Lender within said time frames shall not, standing alone, result in
additional interest expense or other liability to the Borrower.

          Section 2.5.2.  Setoff, etc.  Regardless of the adequacy of any
          -------------   -----------                                    
collateral for any of the Obligations, upon the occurrence and during the
continuance of any Event of Default, each Lender is hereby authorized at any
time and from time to time, without notice to the Borrower (any such notice
being expressly waived by the Borrower), to set off and apply any and all
deposits (general or special, time or demand, provisional or final) at any time
held and any other Indebtedness at any time owing by such Lender to or for the
credit or the account of the Borrower against any and all of the Obligations of
the Borrower irrespective of whether or not such Lender shall have made any
demand under this Agreement or any Note and although such obligations may be
unmatured.  Each such Lender agrees to promptly notify the Borrower and the
Agent after any such setoff and application; provided that the failure to give
such notice shall not affect the validity of such setoff and application.
Promptly following any notice of setoff received by the Agent from a Lender
pursuant to the foregoing, the Agent shall notify each other Lender thereof.
The rights of each Lender under this Section 2.5.2 are in addition to all other
                                     -------------                             
rights and remedies (including, without limitation, other rights of setoff)
which such Lender may have and are subject to Section 9.12.

provided for in this Agreement and the other Financing Documents shall be
unconditional.  Each such payment shall be made without deduction for any claim,
defense or offset of any type, including without limitation any withholdings and
other deductions on account of income or other taxes (except to the extent
provided in Section 2.5.3.2) and regardless of whether any claims, defenses or
            ---------------

contained in this Agreement, the Borrower shall be entitled, to the extent it is
required to do so by law, to deduct or withhold income or interest, fees or
other amounts payable hereunder for the account of any Lender other than a
Lender (i) which is a domestic corporation (as such term is defined in Section
7701 of the Code) for Federal income tax purposes or (ii) who has the prescribed
forms on file with the Borrower for the

          -------------   ------------------------                           
provision of this Agreement, if, prior to or on the date on which all or any
portion of the Loans is to be made as or converted into a Libor Loan, any of the
Lenders (or the Agent with respect to (ii) below) shall reasonably determine
(which determination shall be conclusive and binding on the Borrower), that

             (i)  Dollar deposits in the relevant amounts and for the relevant
     Interest Period are not offered to such Lender in the London interbank
     market,

                                      31
<PAGE>
 
          (ii)  by reason of circumstances affecting the London interbank
     market, adequate and reasonable means do not exist for ascertaining the
     Adjusted Libor Rate, or

          (iii)  the Adjusted Libor Rate shall no longer represent the effective
     cost to such Lender for Dollar deposits in the London interbank market for
     reasons other than the fact, standing alone, that the Adjusted Libor Rate
     is based on an averaging of rates determined by the Agent and that such
     Lender's rate may exceed such average,

such Lender may elect not to accept any Interest Rate Election electing a Libor
Loan and such Lender shall notify the Agent by telephone or telex thereof,
stating the reasons therefor, not later than the close of business on the second
Business Day prior to the date on which such Libor Loan is to be made.   The
Agent shall promptly give notice of such determination and the reason therefor
to the Borrower, and all or such portion of the Loans, as the case may be, which
are subject to any of Section 2.9.2 (i), (ii) through (iii) as a result of such

Lender's determination shall be made as or converted into, as the case may be,
Prime Rate Loans and such Lender shall have no further obligation to make Libor
Loans, until further written notice to the contrary is given by the Agent to the
Borrower.  If such circumstances subsequently change so that such Lender shall
no longer be so affected, such Lender's obligation to make or maintain its Pro
Rata Share of all or any portion of the Loans as Libor Loans shall be reinstated
when such Lender obtains actual knowledge of such change of circumstances and
promptly after obtaining such actual knowledge such Lender shall forward written
notice thereof to the Agent and the Borrower.  Upon or after receipt by the
Borrower of such written notice, the Borrower may submit an Interest Rate
Election in accordance with this Agreement electing an Interest Period ending no
later than the Interest Adjustment Date for the then current Interest Period for
the other Lenders' Pro Rata Shares of Libor Loans and electing the Libor Rate
for such Lenders' or Lender's Pro Rata Share(s) of the Loans as to which such
Lender's or Lenders' obligation(s) to make or maintain its or their Pro Rata
Share(s) of the Loans as Libor Loans was suspended and such Pro Rata Share(s)
shall be converted to Libor Loans in accordance with this Agreement. During any
period throughout which any of the Lenders has or have no obligation to make or
maintain its or their Pro Rata Share(s) of the Loans as Libor Loans, no Interest
Rate Elections electing the Libor Rate shall be effective with regard to the
Loans to the extent of the Pro Rata Share(s) of such Lender(s), but shall be
effective as to the other Lenders.

in applicable laws or regulations (including the introduction of any new
applicable law or regulation) or in the interpretation thereof (whether or not
having the force of law) by any governmental or other regulatory authority
charged with the administration thereof, shall make it unlawful for any of the
Lenders to make or continue to maintain its Pro Rata Share of all or any portion
of the Loans as Libor Loans, each such Lender shall promptly notify the Agent by
telephone or telex thereof, and of the reasons therefor, and the obligation of
such Lender to make or maintain its Pro Rata Share of the Loans or such portion
thereof as Libor Loans shall, upon the happening of such event, terminate and
the Agent shall, by telephonic notice to the Borrower, declare that such
obligation has so terminated with respect to such Lender, and such Pro Rata
Share of the Loans or any portion thereof to the extent then maintained as Libor
Loans, shall, on the last day on which such Lender can lawfully continue to
maintain such Pro Rata Share of the Loans or any portion thereof as Libor Loans,
automatically convert into Prime Rate Loans without additional cost to the
Borrower.  If circumstances subsequently change so that such Lender shall no
longer be so affected, such Lender's obligation to make or maintain its Pro Rata
Share of all or any portion of the Loans as Libor Loans shall be reinstated when
such Lender obtains actual knowledge of such_change of circumstances, and
promptly after obtaining such actual knowledge such Lender shall forward written
notice thereof to the Agent and the Borrower.  Upon or after receipt by the
Borrower of such written notice, the Borrower may submit an Interest Rate
Election in accordance with this Agreement electing an Interest Period ending no
later than the Interest Adjustment Date for the then current Interest Period for
the other Lenders' Pro Rata Shares of Libor Loans and electing the Libor Rate
for such Lenders' or Lender's Pro Rata Share(s) of the Loans as to which such
Lender's or Lenders' obligation(s) to make or maintain its or their Pro Rata
Share(s) of the Loans as Libor Loans was suspended and such Pro Rata Share(s)
shall be converted to Libor Loans in accordance with this Agreement.  During any
period throughout which any of the Lenders has or have no obligation to make or
maintain its or their Pro Rata Share(s) of the Loans as Libor Loans, (i) no
Interest Rate Elections electing the Libor Rate shall be effective with regard
to the Loans to the extent of the Pro Rata Share(s) of such Lender(s), but shall
be effective as to the other Lenders and (ii) any of the Lenders which has or
have no_obligation to make or maintain its or their Pro Rata Share(s) of the
Loans as Libor Loans shall use reasonable efforts to make available to the
Borrower an alternative index for establishing a fixed interest rate facility
providing a yield to such Lenders equal to the Libor Rate, but only to the
extent that any such Lenders, independently and without regard to this

                                      33

Agreement or the Libor Loans, are generally providing such alternative index to
similarly situated customers of such Lenders in the ordinary course of such
Lenders' business.

agrees to pay to the Agent for the account of the applicable Lender or Lenders
such amounts (which shall be deemed additional interest) as will compensate any
of the Lenders for any increase in the cost to such Lender of making or
maintaining (or of its obligation to make or maintain) all or any portion of its
Pro Rata Share of the Loans as Libor Loans and for any reduction in the amount
of any sum receivable by such Lender under this Agreement in respect of making
or maintaining all or any portion of such Lender's Pro Rata Share of the Loans
as Libor Loans, in either case, from time to time by reason of:

          (i)  any reserve, special deposit or similar requirement against
    assets of, deposits with or for the account of, or credit extended by, such
    Lender, under or pursuant to any law, treaty, rule, regulation (including,
    without limitation, any Regulations of the Board of Governors of the Federal
    Reserve System) or requirement in effect on or after the date hereof, any
    interpretation thereof by any governmental authority charged with
    administration thereof or by any central bank or other fiscal or monetary
    authority or other authority, or any requirement imposed by any central bank
    or such other authority whether or not having the force of law; or

          (ii)  any change in (including the introduction of any new)
    applicable law, treaty, rule, regulation or requirement or in the
    interpretation thereof by any official authority, or the imposition of any
    requirement of any central bank, whether or not having the force of law,
    which shall subject such Lender to any tax (other than taxes on net income
    imposed on such Lender), levy, impost, charge, fee, duty, deduction or
    withholding of any kind whatsoever or change the taxation of such Lender
    with respect to making or maintaining all or any portion of its Pro Rata
    Share of the Loans as Libor Loans and the interest thereon (other than any
    change which affects, and to the extent that it affects, the taxation of net
    income of such Lender); provided, that with respect to any withholding the
    foregoing shall not apply to any withholding tax described in sections 1441,
    1442 or 3406 of the Code, or any succeeding provision of any legislation
    that amends, supplements or replaces any such section, or to any tax, levy,
    impost, duty, charge, fee, deduction or withholding that results from any
    noncompliance by a Lender with any federal, state or foreign law or from any
    failure by

                                      34
<PAGE>
 
   a Lender to file or furnish any report, return, statement or form the filing
   or furnishing of which would not have an adverse effect on such Lender and
   would eliminate such tax, impost, duty, deduction or withholding;

In any such event, such Lender shall promptly notify the Agent thereof, and of
the reasons therefor, and the Agent shall promptly notify the Borrower thereof
in writing stating the reasons provided to the Agent by such Lender therefor and
the additional amounts required to fully compensate such Lender for such
increased or new cost or reduced amount as reasonably determined by such Lender.
Such additional amounts shall be payable on each date on which interest is to be
paid hereunder or, if there is no outstanding principal amount under any of the
Notes, within 20 Business Days after the Borrower's receipt of said notice.
Such Lender's certificate as to any such increased or new cost or reduced amount
(including calculations, in reasonable detail, showing how such Lender computed
such cost or reduction) shall be submitted by the Agent to the Borrower and
shall, in the absence of manifest error, be presumptive.  In determining any
such amount, the Lender(s) shall act reasonably and will use reasonable
averaging and attribution methods which will, to the extent such increased costs
or reductions relate to such Lender's loans bearing interest at a rate based on
the Adjusted Libor Rate in general and are not attributable solely to the Loans
hereunder, be applied generally to such Lender's loans bearing interest at a
rate based on the Adjusted Libor Rate and such Lender's Libor Loans.
Notwithstanding anything to the contrary set forth above, the Borrower shall not
be obligated to pay any amounts pursuant to this Section 2.9.4 as a result of
                                                 -------------               
any requirement or change referenced above with respect to any period prior to
the ninetieth (90th) day prior to the date on which the Borrower is first
notified thereof (other than any amounts which relate to any such requirement or
change which is adopted with retroactive effect in which case the Borrower shall
be obligated to pay all such amounts accrued from the date as of which such
requirement or change is retroactively effective) unless the failure to give
such notice within such ninety (90) day period resulted from reasonable
circumstances beyond such Lender's reasonable control.

          -------------   --------------------                                  
prepayment of a Libor Loan is received on a date other than the last day of an
Interest Period, such payment or prepayment shall be held by the Agent in a
separate account and considered pledged to the Agent as collateral for the
obligations of the Borrower arising in connection with this Agreement, the Notes
and the other Financing Documents until the end of the then current Interest
Period, at which time the Agent  shall apply

                                      35
<PAGE>
 
such payment or prepayment, pro rata for the Lenders, to the outstanding Libor
Loans.  Notwithstanding the foregoing, in the event any of the Lenders shall
incur any loss or reasonable expense (including, without limitation, any loss or
reasonable expense incurred by reason of the liquidation or reemployment of
deposits or other funds acquired by such Lender to fund or maintain all or any
portion of the Loans as Libor Loans) as a result of:

              (i)  payment or prepayment by the Borrower of all or any portion
    of any Libor Loan on a date other than the Interest Adjustment Date for such
    Libor Loan, for any reason; provided, however that this clause shall not be
    deemed to grant the Borrower any right to convert a Libor Loan to a Prime
    Rate Loan prior to the end of any Interest Period or to imply such right;

              (ii)  conversion of all or any portion of any Libor Loan on a day
    other than the last day of an Interest Period applicable to such Loan to a
    Prime Rate Loan for any reason including, without limitation, acceleration
    of the Loans upon or after an Event of Default, any Interest Rate Election
    or any other cause whether voluntary or involuntary and whether or not
    referred to or described in this Agreement, other than any such conversion
    resulting solely from application of Sections 2.9.2 or 2.9.3 by any Lender;

its officers, directors, employees or agents shall be liable to any Lender for
any action taken or omitted hereunder or under any of the Financing Documents,
or in connection herewith or therewith unless caused by its or their gross
negligence or willful misconduct.  If the Agent shall request instructions from

affiliates may accept deposits from, lend money to and generally engage in any
kind of banking, trust, financial advisory or other business with the Borrower,
any of the Stockholders, or any Affiliate or Subsidiary as if it were not
performing the duties specified herein, and may accept fees and other

Section 8.3.  Representations and Warranties; No Responsibility or Appraisal of
- -----------   -----------------------------------------------------------------
Creditworthiness.  Each Lender represents and warrants that it has made its own 
- ----------------
independent investigation of the financial condition and affairs of the
Borrower, the Stockholders and any Subsidiaries of any of them in connection
with the making of the Loans hereunder and has made and shall continue to make
its own appraisal of the creditworthiness of the Borrower, the Stockholders and
the Subsidiaries. The Agent shall not have any duty or responsibility, either
initially or on a continuing basis, to make any such investigation or any such
appraisal on behalf of Lenders or to provide any Lender with any credit or other
information with respect thereto whether coming into its possession before the
making of any Loan or any time or times thereafter (except for information
received by the Agent under Section 5.3 hereof which the Agent will promptly

forward to the Lenders), and the Agent shall further not have any responsibility
with respect to the accuracy of or the completeness of the information provided

Section 8.4.  Right to Indemnity.  Each Lender severally agrees to indemnify

the Agent proportionately to its Pro Rata Share of the Loans, to the extent the
Agent shall not have been reimbursed by or on behalf of the Borrower, for and
against any and all liabilities, obligations, losses, damages, penalties,
actions, judgments, suits, costs, expenses (including, without limitation,
counsel fees and disbursements) or disbursements of any kind or nature
whatsoever which may be imposed on, incurred by or asserted against the Agent in
performing its duties hereunder or in any way relating to or arising out of this
Agreement and/or any of the other Financing Documents; provided that no Lender
shall be liable for any portion of such liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses or disbursements
resulting from the Agent's gross negligence or willful misconduct. If any
indemnity furnished to the Agent for any purpose shall, in the

opinion of the Agent, be insufficient or become impaired, the Agent may call
for additional indemnity and cease, or not commence, to do the acts indemnified
against until such additional indemnity is furnished.

Section 8.5.   Payee of Note Treated as Owner.  The Agent may deem and treat
- -----------    ------------------------------                         
the payee of any Note as the owner thereof for all purposes hereof unless and
until a written notice of the assignment or transfer thereof shall have been
filed with the Agent. Any request, authority or consent of any person or entity
who, at the time of making such request or giving such authority or consent, is
the holder of any Note shall be conclusive and binding on any subsequent holder,
transferee or assignee of that Note or of any Note or Notes issued in exchange
for such Note.

          For such time as any of the Indebtedness of the Borrower to any Lender
and/or the Agent shall be unpaid in whole or in part and/or the Commitment is in
effect, the Borrower irrevocably designates the registered agent or agent for

brought in any such court and agrees and consents that any such service of
process upon such agent and written notice of such service to the Borrower by
registered or certified mail shall be taken and held to be valid personal
service upon the Borrower regardless of where the Borrower shall then be doing
business and that any such service of process shall be of the same force and
validity as if service were made upon it according to the laws governing the
validity and requirements of such service in each such state and waives any
claim of lack of personal service or other error by reason of any such service.
Any notice, process, pleadings or other papers served upon the aforesaid

assertion or employment of any right or remedy under any of the Financing
Documents, or otherwise, shall not prevent the concurrent assertion or
employment of any other appropriate right or remedy.

remedy or constitute a waiver of any such Default or Event of Default or an
acquiescence therein.  Every right and remedy given by any of the Financing
Documents or by law to the Agent  and/or any of the Lenders may be exercised

stay or extension law wherever enacted, now or at any time hereafter in force,
which may affect the covenants or the performance of any of the Financing

- -----------   ---------------                              
waiver of any provision of any of the Financing Documents nor consent to any
departure by the Borrower therefrom shall in any event be effective unless the
same shall be in a written notice given to the Borrower by the Agent and
consented to in writing by the Majority Lenders (or by the Agent acting alone if
any specific provision of this Agreement provides that the Agent, acting alone,
may grant such amendment, modification, termination, waiver or departure) and
the Agent shall give any such notice if the Majority Lenders so consent or
direct the Agent to do so; provided, however, that any such amendment,
modification, termination, waiver or consent shall require a written notice
given to the Borrower by the Agent and consented to in writing by all of the
Lenders if the effect thereof is to (i) change any of the provisions affecting
the interest rate on the Loans, (ii) extend or modify the Commitment, (iii)
discharge or release the Borrower from its obligation to repay all principal due

the Borrower to assign any of its rights under or interest in this Agreement,
and then such waiver or consent shall be effective only in the specific instance
and for the specific purpose for which given. Any amendment or modification of
this Agreement must be signed by the Borrower, the Agent and at least all of the
Lenders consenting thereto who shall then hold the Pro Rata Shares of the Loans
required for such amendment or modification under this Section 9.5 and the Agent
                                                       -----------

Section 9.11.    Substitutions and Assignments.  Upon the request of any 
- ------------     -----------------------------
Lender, the Agent and such Lender may, subject to the terms and conditions
hereinafter set forth, take the actions set forth below to substitute one or
more financial institutions having at least $500,000,000 in assets (a
"Substituted Lender") as a Lender or Lenders hereunder having an amount of the
Loans as specified in the relevant Substitution Agreement executed in connection
therewith; provided that no Lender, Selling Lender or Substituted Lender shall
have a Pro Rata Share of the Commitment and the Loans in the aggregate of less
than 25% and Fleet and/or its Affiliates shall retain for their own account at
least 25% of the Term Loan and 25% of the Revolving Credit Loan Commitment.

          Section 9.11.1.  In connection with any such substitution the
          --------------                                               
Substituted Lender and the Agent shall enter into a Substitution Agreement in
the form of Exhibit 9.11.1 hereto (a "Substitution Agreement") pursuant to which
            --------------                                                      
such Substituted Lender shall be substituted for the Lender requesting the
substitution in question (any such Lender being hereinafter referred to as a
"Selling Lender") to the extent of the reduction in the Selling Lender's portion
of the Loans specified therein. In addition, such Substituted Lender shall
assume such of the obligations of each Selling Lender under the Financing
Documents as may be specified in the Substitution Agreement and this Agreement
shall be amended by execution and delivery of each Substitution Agreement to
include such Substituted Lender as a Lender for all purposes under the Financing
Documents and to substitute for the then existing Exhibit 1.9 to this Agreement
                                                  -----------                  
a new Exhibit 1.9 in the form of Schedule A to such Substitution Agreement
      -----------                                                         
setting forth the portion of the Loans belonging to each Lender following
execution thereof.  Each Lender and the Borrower hereby appoint the Agent as
Agent on its behalf to countersign and accept delivery of each Substitution
Agreement and, to the extent applicable, the provisions of Article 8 hereof
shall apply mutatis mutandis with respect to such appointment and anything done
            ------- --------                                                   
or omitted to be done by the Agent in pursuance thereof.  The Agent shall
provide the Borrower with prior written notice of any substitution of any Lender
under this Section 9.11 including the name and Pro Rata Share of the Substituted
           ------------                                                         
Lender.

          Section 9.11.2.  Without prejudice to any other provision of this
          --------------                                                   
Agreement, each Substituted Lender shall, by its execution of a Substitution
Agreement, agree that neither the Agent nor any Lender is any way responsible
for or makes any representation or warranty as to:  (a) the accuracy and/or
completeness of any information supplied to such Substituted Lender in
connection therewith, (b) the financial condition, creditworthiness, affairs,
status or nature of the Borrower, any of the Stockholders and/or any of the
Subsidiaries or the


                                      82
<PAGE>
 
observance by the Borrower, or any other party of any of its obligations under
this Agreement or any of the other Financing Documents or (c) the legality,
validity, effectiveness, adequacy or enforceability of any of the Financing
Documents.

          Section 9.11.3.  The Agent shall be entitled to rely on any
          --------------                                             
Substitution Agreement delivered to it pursuant to this Section 9.11 which is
                                                        ------------         
complete and regular on its face as to its contents and appears to be signed on
behalf of the Substituted Lender which is a party thereto, and the Agent shall
have no liability or responsibility to any party as a consequence of relying
thereon and acting in accordance with and countersigning any such Substitution
Agreement.  The effective date of each Substitution Agreement shall be the date
specified as such therein and each Lender prior to such effective date shall,
for all purposes hereunder, be deemed to have and possess all of their
respective rights and obligations hereunder up to 12:00 o'clock Noon on the
effective date thereof.

          Section 9.11.4.  Upon delivery to the Agent of any Substitution
          --------------                                                 
Agreement pursuant to and in accordance with this Section 9.11 and acceptance
                                                  ------------               
thereof by the Agent (which delivery shall be evidenced and accepted exclusively
and conclusively by the Agent's countersignature thereon pursuant to the terms
hereof without which such Substitution Agreement shall be ineffective): (i)
except as provided hereunder and in Section 9.11.5, the respective rights of
                                    --------------                          
each Selling Lender and the Borrower against each other under the Financing
Documents with respect to the portion of the Loans being assigned or delegated
shall be terminated and each Selling Lender and the Borrower shall each be
released from all further obligations to the other hereunder with respect
thereto (all such rights and obligations to be so terminated or released being
referred to in this Section 9.11 as "Discharged Rights and Obligations"); and
                    ------------                                             
(ii) the Borrower and the Substituted Lender shall each acquire rights against
each other and assume obligations towards each other which differ from the
Discharged Rights and Obligations only in so far as the Borrower and the
Substituted Lender have assumed and/or acquired the same in place of the Selling
Lender in question; and (iii) the Agent, the Substituted Lender and the other
Lenders shall acquire the same rights and assume the same obligations between
themselves as they would have acquired and assumed had such Substituted Lender
been an original party to this Agreement as a Lender possessing the Discharged
Rights and Obligations acquired and/or assumed by it in consequence of the
delivery of such Substitution Agreement to the Agent.

          Section 9.11.5.  Discharged Rights and Obligations shall not include,
          --------------                                                       
and there shall be no termination or release pursuant to this Section 9.11 of
                                                              ------------   
(i) any rights or obligations


                                      83
<PAGE>
 
arising pursuant to any of the Financing Documents in respect of the period or
in respect of payments hereunder made during the period prior to the effective
date of the relevant Substitution Agreement or, (ii) any rights or obligations
relating to the payment of any amount which has fallen due and not been paid
hereunder prior to such effective date or rights or obligations for the payment
of interest, damages or other amounts becoming due hereunder as a result of such
nonpayment.

                Section 9.11.6.  With respect to any substitution of a 
                --------------
Substituted Lender taking place after the Closing Date, the Borrower shall issue
to such Substituted Lender and to such Selling Lender, new Notes reflecting the
inclusion of such Substituted Lender as a Lender and the reduction in the
respective Loans of such Selling Lender, such new Notes to be issued against
receipt by the Borrower of the existing Notes of such Lender which shall be
marked "cancelled". The Selling Lender or the Substituted Lender shall pay to
the Agent for its own account an assignment fee in the amount of $3,000 for each
assignment hereunder, which shall be payable at or before the effective date of
the assignment.

                Section 9.11.7.  Each Lender may furnish to any financial 
                --------------
institution having at least $500,000,000 in assets which such Lender proposes to
make a Substituted Lender or to a Substituted Lender any information concerning
such Lender, the Borrower, Stockholders and any Subsidiary in the possession of
that Lender from time to time; provided that any Lender providing any
confidential information about the Borrower, any of the Stockholders and/or any
Subsidiary to any such financial institution shall first obtain such financial
institution's agreement to keep confidential any such confidential information.

          Section 9.12.  Payments Pro Rata.  The Agent agrees that promptly
          ------------   -----------------                                 
after its receipt of each payment from or on behalf of the Borrower in respect
of any obligations of the Borrower hereunder it shall distribute such payment to
the Lenders pro rata based upon their respective Pro Rata Shares, if any, of the
obligations with respect to which such payment was received. Each of the Lenders
agrees that, if it should receive any amount hereunder (whether by voluntary
payment, by realization upon security, by the exercise of the right of setoff
under Section 2.5.2 or otherwise or banker's lien, by counterclaim or cross
      -------------                                                        
action, by the enforcement of any right under the Financing Documents, or
otherwise), which is applicable to the payment of the Obligations of a sum which
with respect to the related sum or sums received by other Lenders is in a
greater proportion than the total amount of such Obligation then owed and due to
such Lender bears to the total amount of such Obligation then owed and


                                      84
<PAGE>
 
due to all of the Lenders immediately prior to such receipt, except for any
amounts received pursuant to Section 2.2.3, then such Lender receiving such
                             -------------                                 
excess payment shall purchase for cash without recourse or warranty from the
other Lenders an interest in the Obligations of the Borrower to such Lenders in
such amount as shall result in a proportional participation by all the Lenders
in such amount; provided further, however, that if all or any portion of such
excess amount is thereafter recovered from such Lender, such purchase shall be
rescinded and the purchase price restored to the extent of such recovery, but
without interest.

          Section 9.13  Indemnification.  The Borrower irrevocably agrees to and
          ------------  ---------------                                         
does hereby indemnify and hold harmless Agent and each of the Lenders, their
agents or employees and each Person, if any, who controls any of the Agent and
the Lenders within the meaning of Section 15 of the Securities Act of 1933, as
amended, and each and all and any of them (the "Indemnified Parties"), against
any and all losses, claims, actions, causes of action, damages (excluding
consequential damages) or liabilities (including any amount paid in settlement
of any action, commenced or threatened and any amount described in Section 8.4)
                                                                   ----------- 
(collectively, the "Damages"), joint or several, to which they, or any of them,
may become subject under statutory law or at common law, and to reimburse the
Indemnified Parties for any legal or other out-of-pocket expenses reasonably
incurred by it or them in connection with investigating, preparing for or
defending against any of the Indemnified Parties, insofar as such losses,
claims, damages, liabilities or actions arise out of or are related to any act
or omission of the Borrower and/or any Subsidiary with respect to any of the
Related Transactions, this Agreement, any of the Notes, any of Loans and/or any
offering of securities by the Borrower and/or any Subsidiary after the date
hereof and/or in connection with the Securities and Exchange Act of 1933 and/or
failure to comply with any applicable federal, state or foreign governmental
law, rule, regulation, order or decree, including without limitation, any
Damages which arise out of or are based upon any untrue statement or alleged
untrue statement of a material fact with respect to matters relative to any of
the foregoing contained in any document distributed in connection therewith, or
the omission or alleged omission to state in any of the foregoing a material
fact necessary to make the statements therein, in the light of the circumstances
under which they were made, not misleading, but excluding any Damages to the
extent arising from or due to the gross negligence or willful misconduct of any
of the Indemnified Parties.

          Promptly upon receipt of notice of the commencement of any action, or
information as to any threatened action against any of


                                      85
<PAGE>
 
the Indemnified Parties in respect of which indemnity or reimbursement may be
sought from the Borrower on account of the agreement contained in this Section
                                                                       -------
9.13, notice shall be given to the Borrower in writing of the commencement or
- ----                                                                         
threatening thereof, together with a copy of all papers served, but the omission
so to notify the Borrower of any such action shall not release the Borrower from
any liability which it may have to such Indemnified Parties unless, and only to
the extent that, such omission materially prejudiced Borrower's ability to
defend against such action.

          In case any such action shall be brought against any of the
Indemnified Parties, the Borrower shall be entitled to participate in (and, to
the extent that it shall wish, to select counsel and to direct) the defense
thereof at its own expense. Any of the Indemnified Parties shall have the right
to employ its or their own counsel in any case, but the fees and expenses of
such counsel shall be at the expense of such Indemnified Party unless the
employment of such counsel shall have been authorized in writing by the Borrower
in connection with the defense of such action or the Borrower shall not have
employed counsel to have charge of the defense of such action or such
Indemnified Party shall have received an opinion from an independent counsel
that there may be defenses available to it which are different from or
additional to those available to the Borrower (in which case the Borrower shall
not have the right to direct the defense of such action on behalf of such
Indemnified Party), in any of which events the same shall be borne by the
Borrower.  If any Indemnified Party settles any claim or action with respect to
which the Borrower has agreed to indemnify such Indemnified Party pursuant to
the terms hereof, the Borrower shall have no liability pursuant to this Section
                                                                        -------

Borrower shall have consented in writing to the terms of such settlement.

          The provisions of Section 9.13 shall be effective only to the fullest
                            ------------                                       
extent permitted by law.

          Section 9.13A.  Governing Law.  This Agreement and each Note shall be
          -------------   -------------                                        
governed by, and construed in accordance with, the laws of The Commonwealth of
Massachusetts.

          ------------    --------------------------                        
Agreement which is prohibited or unenforceable in any jurisdiction shall, as to
such jurisdiction, be ineffective to the extent of such prohibition or
unenforceability without invalidating the remaining provisions hereof or
affecting the validity or enforceability of such provision in any other
jurisdiction.

                               NET MASTER LEASE


          THIS LEASE is made in duplicate this 11th day October, 1994, by and
between PLUMTREE OFFICE INVESTORS, LTD., a Colorado limited partnership,
hereinafter called "Lessor", and R & D SYSTEMS COMPANY, a Colorado corporation,
hereinafter collectively called "Lessee."

                                  WITNESSETH:

          That in consideration of the payment of the rent and the keeping and
performance of the covenants and agreements by Lessee, as hereinafter set forth,
Lessor has agreed to lease and hereby does lease and demise unto Lessee that
certain office building known and described as Plumtree Center, consisting of
approximately 45,000 rentable square feet, described as Lot 1, Plumtree Center,
Filing Number 2, El Paso County, Colorado, hereinafter called the "Leased
Premises", and the address of which is 5225 N. Academy Boulevard, Colorado
Springs, CO 80918, hereinafter called the "Building".

          TO HAVE AND TO HOLD the same, with all the appurtenances, unto Lessee,
from 12 o'clock noon on the day of closing of the purchase of the Building by
Lessor for, during and until 12 o'clock noon on the day which is four (4) years
after the date of closing, hereinafter the "Lease Term," at and for a Base Rent
for the full term aforesaid in the sum of One Million Eight Hundred Thousand and
no/100 Dollars ($1,800,000.00), payable in installments, the initial payment
being the sum of Thirty-Seven Thousand Five Hundred and no/100 Dollars
($37,500.00), together with additional rent as set forth hereinafter, due upon
execution of this Lease.  Thereafter installments of Thirty-Seven Thousand Five
Hundred and no/100 Dollars ($37,500.00) per month, together with additional rent
as set forth hereinafter, shall be paid in advance, the first such installment
being due and payable on the first calendar month following the month in which
falls the first day of this Lease with other installments being due and payable
on the first day of each and every calendar month of said term thereafter until
the full payment of the total sum shall be made.  Base Rental Rate shall mean
$10.00 per rentable square foot of the Leased Premises.  All rentals shall be
paid without notice at the office of Lessor in accordance with Paragraph 4
below.

                                 1.   SERVICES
                                      --------

          Lessee understands that Lessor shall designate a property management
company to supply property management services to the Building.  The costs of
these services, together with other services supplied to Lessee, shall be paid
by Lessee to Lessor as additional rent in accordance with the more specific
provisions of this Lease.  Lessor agrees to supply to Lessee heating,
electrical, air conditioning, sewer and plumbing, elevator, trash, snow and ice
removal, janitorial, lighting, property management services, and other contract
services in accordance with the custom for comparable first class office
buildings in the Colorado Springs area and the costs of all such services shall
be based upon commercially reasonable rates.  In the event of any interruption,
reduction or discontinuance of services which is beyond Lessor's control, Lessor
shall not be liable for damages to persons or property as a result thereof, nor
shall the occurrence of any such event in any way be construed as an eviction of
Lessee or cause or permit an abatement, reduction or setoff of rent, or operate
to release Lessee from any of Lessee's
<PAGE>
 
obligations hereunder. In the event of any such interruption, reduction or
discontinuance of service, Lessor must demonstrate a diligent effort to effect
such repairs as soon as reasonably possible. If Lessor's failure to make such
diligent effort results in three (3) consecutive days of interruption of such
services and such interruption does not result from either (a) Lessee's actions
or omissions, or from (b) actions or omissions under the control of any public
authority or utility provider, rent, and additional rent shall be abated for
each day of further interruption and such abatement will be Lessee's sole
remedy.

                              2.   QUIET ENJOYMENT
                                   ---------------

          Subject to the provisions of this Lease, Lessor covenants that Lessee
on paying the rent and performing the covenants of this Lease on its part to be
performed, shall and may peacefully and quietly have, hold and enjoy the
Premises for the term of this Lease.  Lessor shall not be responsible for the
acts or omissions of any third party which may interfere with Lessee's use and
enjoyment of the Premises.

                              3.  PAYMENT OF RENT
                                  ---------------

          A.   BASE RENT.  Lessee agrees to pay all Base Rents, Additional
               ---------                                                  
Rents, and sums to be paid to Lessor under this Lease at the times and in the
manner herein provided without notice or demand.  Rental checks will be made
payable to the order of Plumtree Office Investors, Ltd., and be paid at c/o
Diamante Properties Corp., 121 East Pikes Peak Avenue, Suite 335, Colorado
Springs, Colorado 80903.  Lessor reserves the right to change the party to whom
payment will be made and the address of the same by providing five (5) days
prior written notice to Lessee.  Notwithstanding the foregoing, Lessee shall be
entitled to collect all rents payable from subtenants of the Building so long as
Lessee is not in default hereunder.

          Lessee's covenants to pay rental and other sums due under this Lease
are independent of any other covenant, condition, provision or agreement herein
contained, and said rental payments shall not be subject to setoff or deductions
of any kind by Lessee, with the exception that Lessee may setoff against amounts
owing under this Lease any amounts not paid when due by Lessor under Note and
the Deed of Trust dated October 11, 1994 encumbering the premises for the
benefit of Plumtree of Colorado Springs.

          B.   ADDITIONAL RENT.  In addition to the foregoing, it is hereby
               ----------------                                            
agreed that Lessee shall pay to Lessor as Additional Rent during each calendar
year during the term hereof, all "Real Estate Taxes," all costs of water and
sanitary and storm drainage services, all charges for electricity, gas, fuel,
telephone, trash removal, snow removal, janitorial services, a property
management fee to the management firm designated by Lessor from time to time
equal to four and one-half percent (4-1/2%) of the Base Rent payable with
respect to the Building, all insurance costs associated with the Building, and
all other utility costs, common area maintenance and repair costs, elevator and
HVAC maintenance costs, and all costs of maintaining the building as a first-
class office building (collectively "Charges").

          (1) For purposes hereof, "Real Estate Taxes" shall mean all real
property taxes and assessments levied against the Building by any governmental
or quasi-governmental authority, including any taxes, assessments, surcharges,
or service or other fees of a nature not

                                       2
<PAGE>
 
presently in effect which shall hereafter be levied on the Building as a result
of the use, ownership or operation of the Building or for any other reason,
whether in lieu of or in addition to any current real estate taxes and
assessments; provided, however, that any taxes which shall be levied on the
rentals of the Building shall be determined as if the Building was Lessor's only
property and provided further, that in no event shall the term "Taxes and
Assessments," as used herein, include any federal, state or local income taxes
levied or assessed on Lessor, unless such taxes are a specific substitute for
real property taxes; such term shall, however, include gross taxes on rentals
and expenses incurred by Lessor for consultants which have been approved in
advance in writing by Lessee, whose approval shall not be unreasonably withheld
or delayed, and in contesting the amount or validity of any such Taxes or
Assessments (all of the foregoing are collectively referred to herein as
"Taxes"). "Assessments" shall include any and all so-called special assessments,
license tax, business license fee, business license tax, commercial rental tax,
levy, charge or tax imposed by any authority having the direct power to tax,
including any city, county, state or federal government, or any school,
agricultural, lighting, water, drainage or the improvement or special district
thereof, against the Premises or the Building, or against any legal or equitable
interest of Lessor therein. For the purposes of this Lease, any special
assessment shall be deemed payable in such number of installments as is
permitted by law, whether or not actually so paid. In addition, Lessee shall be
liable for and shall pay before delinquency and Lessee hereby agrees to
indemnify and hold Lessor harmless from and against any liability in connection
with all taxes levied against any personal property, fixtures, machinery,
equipment, apparatus, systems and appurtenances placed by or on behalf of Lessee
in or about the Premises ("Equipment Taxes"). If any Equipment Taxes are levied
against Lessor or Lessor's property or if the assessed value of Lessor's
property is increased by the inclusion therein of a value placed upon such
personal property, fixtures, machinery, equipment, apparatus, systems or
appurtenances of Lessee, and if Lessor, after written notice to Lessee, pays the
Equipment Taxes or taxes based upon such an increased assessment (which Lessor
shall have the right to do regardless of the validity of such levy, but under
proper protest if requested by Lessee prior to such payment and if payment under
protest is permissible), Lessee shall pay to Lessor upon thirty (30) days
advance notice, as Additional Rent hereunder, the taxes so levied against Lessor
or the proportion of such taxes resulting from such increase in the assessment;
provided, however, that in any such event, Lessee shall have the right, on
behalf of Lessor, to bring suit in any court of competent jurisdiction to
recover the amount of any such tax so paid under protest, and any amount so
recovered shall belong to Lessee (provided Lessee has previously paid such
amount to Lessor). Notwithstanding the foregoing to the contrary, Lessee shall
cooperate with Lessor to the extent reasonably necessary to cause the fixtures,
furnishings, equipment and other personal property to be assessed and billed
separately from the real property of which the Premises form a part, and the
Lessor shall use reasonable efforts to treat all other tenants on the same
basis.

          (2) Lessee shall pay to Lessor as Additional Rent during each calendar
year during the term hereof, in advance on the first (1st) day of each month, an
estimate of the Charges for the calendar year as reasonably estimated by Lessor,
at the rate of one twelfth (1/12) thereof, on the same date and at the same
place Base Rent is payable, with an adjustment to be made between the parties at
a later date as hereinafter provided.  Lessor shall deliver to Lessee within
ninety (90) days following the end of one calendar year an estimate of the
Charges for the new calendar year (the "Budget Sheet").  Until receipt of the
Budget Sheet, Lessee shall continue to pay its monthly Charges based upon the
estimate for the preceding calendar year.  To the extent that the Budget Sheet
reflects an estimate of Charges for the new calendar year greater

                                       3
<PAGE>
 
than the amount actually paid to the date of receipt of the Budget Sheet for the
new calendar year, Lessee shall thereafter pay the amount of its monthly Charges
as set forth in the Budget Sheet. As soon as practicable following the end of
any calendar year, but not later than April 1st, Lessor shall submit to Lessee a
statement in reasonable detail, with supporting documentation if requested by
Lessee, describing the computations of the Charges for the calendar year just
completed (the "Statement"), and the differences, if any, between the actual
Charges for the calendar year just completed and the actual amount of the
Charges paid by Lessee to Lessor. To the extent that the actual Charges for the
period covered by the Statement is higher than the estimated Charges which
Lessee previously paid during the calendar year just completed, Lessee shall
also pay to Lessor such balance within thirty (30) days following receipt of the
Statement from Lessor. To the extent that the actual Charges for the period
covered by the Statement is less then the estimated Charges which Lessee
previously paid during the calendar year just completed, Lessor shall credit,
within thirty (30) days, the excess against any sums then owing or next becoming
due from Lessee under this Lease.

          C.   NET LEASE.  Lessor and Lessee agree that the Base Rent paid
               ---------                                                  
hereunder shall be completely net to Lessor and Lessee shall be responsible for
the payment to Lessor, as Additional Rent, of all expenses of every kind and
nature related to the occupancy, operation, maintenance and repair of the
Building (collectively "Operating Expenses"), including, without limiting the
generality of the foregoing, all costs incurred in an effort to maintain the
Building in the condition of a first-class office building.  Lessee will pay as
Additional Rent its share, if any, of any common area charges for the Building.
For purposes of this Lease, "common area" shall refer to areas of the Property
and Building which are not reserved for the exclusive use of any tenant and
common areas within the Plumtree Center for which the Building is assessed a
share of the costs of operating and maintaining in accordance with the
Declaration of Covenants for Plumtree Center or any maintenance agreements
pertaining to the Plumtree Center or any maintenance agreements pertaining to
the Plumtree Center, as the same may be amended from time to time.
Notwithstanding the foregoing, Lessee shall not be responsible for the cost of
any curative action required of, or repair, replacement or alteration made by
Lessor to (i) remedy damages caused by or resulting from the negligence or
tortious actions of Lessor or Lessor's agents; (ii) costs in connection with a
transfer or disposition of all or any portion of the building and/or the
Building Complex; and (iii) accounting, legal or other fees incurred in
connection with the preparation of Lessor's income tax returns.  Operating
Expenses will include costs of capital improvements which reduce other Operating
Expenses or which are required under any governmental law or regulation,
provided that these costs are amortized over the useful life of the improvement.
Operating Expenses will not include depreciation on the Building, brokerage
commissions, the costs of any items for which Lessor is reimbursed by insurance,
the costs of any interior maintenance within the offices of Lessee to the extent
such areas are maintained by Lessee, and the costs of any capital expenditures
to the extent they upgrade or improve the Building as opposed to repairing or
replacing existing items.

          D.   RETURNED CHECK FEE.  A fee of the greater of $100.00 or actual
               ------------------                                            
cost associated with any returned check shall be paid by the Lessee to the
Lessor for any returned check.

                                  4.   DEPOSIT
                                       -------

          Lessee, concurrently with the execution of this Lease, has deposited
with Lessor and shall keep on deposit in an interest-bearing account at all
times during the term of this Lease, the sum of Thirty-Seven Thousand Five
Hundred and no/100 Dollars ($37,500.00) for the purpose hereinafter set forth,
to be held by Lessor.  If at any time during the term of this Lease, Lessee
shall be in default in the performance of any of the terms, provisions,
covenants or conditions of this Lease, Lessor shall have the right to apply said
deposit, or so much thereof as may be necessary, toward damage to the Leased
Premises, the costs or expenses associated with such default, and for any
attorney's fees and legal costs incurred by Lessor by reason of such default;
and in the event such deposit shall be diminished by any such payment from or
application of the same, Lessee shall and will forthwith pay to Lessor, or its
agent, as Lessor may request, such sum as shall be necessary to restore said
deposit to the original amount mentioned above.  Provided that Lessee is not
then in default under this Lease, on each anniversary date of this Lease all
interest that has accrued on the security deposit shall be paid by Lessor to
Lessee.  If the amount of said deposit shall be insufficient to pay, reimburse
and fully discharge such expenses and damages, Lessee shall be and remain liable
for the balance thereof remaining unpaid, and shall pay the amount of such
deficiency to Lessor.  Within thirty (30) days after the termination of the
Lessee's tenancy, Lessor shall return to Lessee such part or portion of said
deposit, plus accrued interest, as shall not be required to pay, discharge and
reimburse Lessor for the said expenses and damages.

          In the event the property in which the Leased Premises is located is
sold or otherwise conveyed, or a new management agent is named by Lessor, said
security deposit shall be transferred by Lessor to the new owner of the property
or new management agent, and notice thereof acknowledged by the new owners shall
be given to Lessee, and upon such transfer, Lessor shall be released from any
and all liability associated therewith.

                                 5.  INSURANCE
                                     ---------

          A.   "ALL-RISK" COVERAGE.  Lessor will, at the expense of Lessee as
                ------------------                                              
Additional Rent, obtain and keep in force from the commencement of construction
of the improvements to the Premises and during the term of this Lease, "all-
risk" coverage insurance naming Lessor and Lessee as their interests may appear
and such other parties as Lessor or Lessee may designate as additional insureds,
in the customary form in the City of Colorado Springs for buildings and
improvements of similar character, on all buildings and improvements now or
after this date located on the Premises.  The amount of insurance will be
designated by Lessor no more frequently than once every twelve (12) months; will
be set forth on an "agreed amount endorsement" to the policy of insurance; will
not be less than the agreed value of the buildings and improvements; and will be
subject to arbitration pursuant to this Lease if Lessor and Lessee do not agree
with regard to the value.  Lessor and Lessee agree that the value of the
existing building on the premises as of the date this Lease is executed is
$4,000,000.00.

          B.   GENERAL LIABILITY.  Lessee will, at its sole expense, obtain and
               -----------------                                               
keep in force during the term of this Lease commercial general liability
insurance with a combined single limit of not less than $1,000,000.00 for injury
to or death of any one person, for injury to or death of 

                                       5
<PAGE>
 
any number of persons in one occurrence, and for damage to property, insuring
against any and all liability of Lessee, including without limitation coverage
for contractual liability, host liquor liability, and non-owned automobile
liability, with respect to the Premises or arising out of the use or occupancy
of the Premises. Such insurance will insure the performance by Lessee of the
indemnity agreement as to liability for injury to or death of persons and damage
to property set forth in this Lease. Such insurance will be noncontributing with
any insurance that may be carried by Lessor. The limits and coverage of all such
insurance will be adjusted by agreement of Lessor and Lessee during every third
lease year during the term of this Lease in conformity with the then prevailing
custom of insuring liability in the City of Colorado Springs, and any
disagreement regarding such adjustment will be submitted to arbitration in the
manner provided in this Lease.

          C.   OTHER MATTERS.  All insurance required in this paragraph and all
               -------------                                                   
renewals of it will be issued by companies authorized to transact business in
the State of Colorado and rated at least a Class X by Best's Insurance Reports
(property liability) or approved by Lessor.  The builder's "all-risk" coverage
insurance will be payable to Lessor, Lessee, and any lender as their interests
may appear.  The "all-risk" coverage insurance and the general liability
insurance will be carried in the joint names of Lessee, Lessor, and such other
parties having an interest in the Premises as Lessor and Lessee may designate.
All insurance policies will be subject to approval by Lessor and any lender as
to form and substance; will expressly provide that such policies will not be
canceled or altered without thirty (30) days' prior written notice to Lessor and
any lender, in the case of "all-risk" coverage insurance, and to Lessor, in the
case of general liability insurance; will, to the extent obtainable, provide
that no act or omission of Lessee that would otherwise result in forfeiture or
reduction of the insurance will affect or limit the obligation of the insurance
company to pay the amount of any loss sustained; and will, to the extent
obtainable, contain a waiver by the insurer of its rights of subrogation against
Lessor.  Upon issuance, each insurance policy or a duplicate or certificate of
such policy will be delivered to Lessor and any lender whom Lessor designates.
Lessee may satisfy its obligation under this paragraph by appropriate
endorsements of its blanket insurance policies.

          D.   ADDITIONAL INSUREDS.  All policies of liability insurance that
               -------------------                                           
Lessee is obligated to maintain according to this Lease (other than any policy
of workmen's compensation insurance) will name Lessor and such other persons or
firms as Lessor specifies from time to time as additional insureds.  A current
certificate of insurance shall be delivered to Lessor displaying that the
coverages required by this Lease are in full force and effect at all times
during the term of this Lease.  All public liability, property damage liability,
and casualty policies maintained by Lessee will be written as primary policies,
not contributing with and not in excess of coverage that Lessor may carry.  No
insurance required to be maintained by Lessee by this paragraph will be subject
to any deductible without Lessor's prior written consent.

                            6.  HAZARDOUS MATERIALS
                                -------------------

          (1) Lessee shall not cause or permit any Hazardous Material to be
brought upon, kept, or used in or about the Premises by Lessee, its agents,
employees, contractors, licensees or invitees, without the prior written consent
of Lessor.  If Lessee breaches the obligations stated in the preceding sentence,
or if the presence of Hazardous Material on the Premises caused or permitted by
Lessee results in contamination of the Premises of Building, or 

                                       6
<PAGE>
 
any part thereof, or if contamination of the Premises or Building by Hazardous
Material otherwise occurs for which Lessee is legally liable to Lessor for
damage resulting therefrom, then Lessee shall indemnify, defend and hold Lessor,
its agents, employees, legal representatives, successors and assigns, harmless
from any and all claims, judgments, damages, penalties, fines, costs
liabilities, or losses (including, without limitation, diminution in value of
the Premises and Building, damages for the loss or restriction on use of any
rentable or usable space or of any amenity of the Premises or Building, damages
arising from any adverse impact on marketing of space in the Building, and sums
paid in settlement of claims, attorneys' fees, consultant fees and expert fees)
which arise during or after the Lease term as a result of such contamination.
This indemnification of Lessor by Lessee includes, without limitation, costs
incurred in connection with any investigation of site conditions or any cleanup
remedial, removal or restoration work required by any federal, state, or local
governmental agency or political subdivision because of Hazardous Material
present in or about the Building or the soil or ground water on or under the
building. Without limiting the foregoing if the presence of any Hazardous
Material on or about the Building caused or permitted by Lessee results in any
contamination of any portion thereof, Lessee shall promptly take all actions at
its sole expense as are necessary to return the Building to the condition
existing prior to the introduction of such Hazardous Material, subject to
obtaining Lessor's prior written consent to the actions to be taken by Lessee.
Lessor may properly require its consent to the selection of the contractors and
other experts involved in the inspection, testing and removal or abatement
activities, the scope of activities to be performed, the manner and method for
performance of such activities, and such other matters as may be required or
requested by Lessor for the safety of and continued use of the Building and all
occupants thereof. The obligation and liabilities of Lessee herein shall survive
expiration or termination of this Lease.

          (2) "Hazardous Material," as used in this Lease, shall be construed in
its broadest sense and shall include asbestos, other asbestotic material (which
is currently or may be designated in the future as a Hazardous Material), any
petroleum base products, pesticides, paint and solvents, polychlorinated
biphenyl, lead, cyanide, DDT, acids, ammonium compounds and other chemical
products (excluding commercial use cleaning materials in ordinary quantities)
and any substance or material if defined or designated as a hazardous or toxic
substance, or other similar term, by any federal, state or local law statute,
regulation or ordinance affecting the Building or Premises presently in effect
or that may be promulgated in the future, as such statutes, regulations and
ordinances may be amended from time to time.

          (3) The provisions of this Section 6 shall not be applicable with
respect to the dentist currently occupying a portion of the Premises, so long as
such dentist complies with all applicable laws and ordinances pertaining to
Hazardous Materials.

                          7.   CHARACTER OF OCCUPANCY
                               ----------------------

          Lessee agrees to occupy the Leased Premises for general offices only
and to use them in a careful, safe and proper manner; to pay promptly for any
damage to the Leased Premises; not to use or permit the Leased Premises to be
used for any purposes prohibited by the laws of the United States or any
applicable law, statute, regulation or ordinance.  Lessee further agrees that it
will not commit waste nor suffer nor permit waste to be committed nor permit any
nuisance on or in the Leased Premises.  Lessee shall procure, at its sole
expense, all permits and licenses

                                       7
<PAGE>
 
required for the operation of the Building. Lessee shall make, at its sole
expense, all repairs and improvements required in order to comply with any law,
statute, regulation, or ordinance. In addition, the terms of this Lease shall be
subject in all respects to the provisions of all covenants affecting the
Building, including the Declaration of Covenants for Plumtree Center, as the
same may be amended from time to time, and any failure by Lessee to comply with
the terms and provisions thereof shall be a default under this Lease.

                           8.   ALTERATIONS BY LESSOR
                                ---------------------

          Lessee agrees to permit Lessor at any time upon reasonable advance
notice and prior written consent, which shall not be unreasonably withheld
(except in the event of an emergency), to enter the Leased Premises to examine
and inspect the same or make such repairs, additions or alterations as Lessor
may deem necessary or proper for the safety, improvement or preservation
thereof, and it is expressly understood that Lessor shall at all times have the
right at its election to make such alterations or changes in other portions of
the Building as it may from time to time deem necessary and desirable, as long
as such alterations and changes do not unreasonably interfere with Lessee's use
and occupancy of the Leased Premises.

                           9.  ALTERATIONS BY LESSEE
                               ---------------------

          Lessee agrees to make no alterations in or additions to the Leased
Premises without first obtaining the written consent of Lessor; and all
alterations, additions or improvements made by either party at the expense of
the Lessee (except only movable office furniture not attached to the Building)
shall be deemed a part of the real estate and the property of Lessor and shall
remain upon and be surrendered with the Leased Premises as a part thereof,
without molestation, disturbance or injury at the end of said term, whether by
lapse of time or otherwise.  At its option, Lessor may require removal of all
improvements made by Lessee to the Leased Premises and that the Leased Premises
be returned to their condition at the time this Lease was executed, unless the
parties agree at the time Lessor grants its consent to such alterations that
such removal shall not be required.  In the event Lessee makes any additions,
alterations or improvements in excess of $1,000.00, a performance bond shall be
posted by the Lessee insuring the Lessor against any liability for mechanic's
liens.

          All improvements to the Leased Premises if requested in writing by
Lessee and approved by Lessor shall be made at the sole cost and expense of
Lessee.  Lessee shall comply with all requirements of Lessor with respect to the
proposed improvements, including, without limiting the generality of the
foregoing the following:

          (1) The Improvements will not result in a violation of or require a
change in any certificate of occupancy applicable to the Premise or to the
Building;

          (2) The character, outside appearance of the Building or any part
thereof shall not be changed in any material way without Lessor's consent which
consent shall not be unreasonably withheld, and such Improvements shall not
adversely affect or weaken or impair (temporarily or permanently) the structure
of the Premises or Building, either during the making of such Improvements or
upon their completion;

                                       8
<PAGE>
 
          (3) In performing the work involved in making such Improvements,
Lessee shall be bound by and observe all of the terms of this Lease and any
applicable laws, regulations, or covenants affecting the Building; and

          (4) Lessee shall provide notice to Lessor at least ten (10) business
days prior to commencement of any Improvements, and Lessor shall be entitled to
post notices on and about the Premises with respect to Lessor's non-liability
for mechanics' liens and Lessee shall not permit such notices to be defaced or
removed.

          All Improvements to the Premises, including, by way of illustration
but not by limitation, all counters, screens, grilles, special cabinetry work,
fixed partitions and panelling, carpeting, drapes or other window coverings and
light fixtures, shall be deemed a part of the real estate and the property of
Lessor and shall remain upon and be surrendered with the Premises as a part
thereof without molestation, disturbance or injury at the end of the Lease term.
All movable partitions, machines and equipment which are installed in the
Premises by or for Lessee, without expense to Lessor, and can be removed without
structural damage to or defacement of the Building or the Premises, and all
furniture, furnishings and other articles of personal property owned by Lessee
and located in the Premises (all of which are herein called "Lessee's Property")
shall be and remain the property of Lessee and may be removed by it at any time
during the term of this Lease.  However, if any of Lessee's Property is removed,
Lessee shall repair or pay the cost of repairing any damage to the Building or
the Premises resulting from such removal.  All additions or improvements which
are to be surrendered with the Premises shall be surrendered with the Premises,
as a part thereof, at the end of the term or the earlier termination of this
Lease.

          If Lessor permits persons requested by Lessee to perform any
Improvements to the Premises, which consent shall not be unreasonably withheld,
then prior to the commencement of any such work costing $1,000.00 or more in any
one instance, Lessee shall deliver to Lessor certificates issued by insurance
companies qualified to do business in the State of Colorado evidencing that
workmen's compensation, public liability insurance and property damage
insurance, all in amounts, with companies and on forms satisfactory to Lessor,
are in force and maintained by all such contractors and subcontractors engaged
by Lessee to perform such work.  All such policies shall name Lessor as an
additional insured and shall provide that the same may not be canceled or
modified without thirty (30) days prior written notice to Lessor.  Lessor shall
respond within five business days to any written request for consent to
Improvements.  If Lessor shall fail to respond, Lessor's consent to such
improvements shall be presumed to have been given.

          Lessee shall not permit any lien or claim for lien of any mechanic,
laborer or supplier or any other lien to be filed against the Building, the
common areas, the land which comprises the Building, or any part of such
property arising out of work performed, or alleged to have been performed by, or
at the direction of, or on behalf of Lessee.  If Lessee fails to have such lien
or claim for lien so released or to deliver such bond to Lessor, Lessor without
investigating the validity of such lien, may pay or discharge.

          Lessee hereby agrees to indemnify, defend and save Lessor harmless of
and from all liability, loss, damages, costs or expenses, including attorneys'
fees, incurred in connection with any claims of any nature whatsoever for work
performed for, or materials or supplies furnished to 

                                       9
<PAGE>
 
Lessee, including lien claims of laborers, materialmen and others. Should any
such liens be filed or recorded against the Building with respect to work done
for or materials supplied to or on behalf of Lessee or should any action
affecting the title thereto be commenced, Lessee shall cause such liens to be
released of record within twenty (20) days after notice thereof. If Lessee
desires to contest any such claim of lien, Lessee shall nonetheless cause such
lien to be insured against by purchase of a bond from a title company
satisfactory to Lessor at Lessee's expense. If Lessee shall be in default in
paying any charge for which such a mechanic's lien or suit to foreclose such a
lien has been recorded or filed and shall not have caused the lien to be
released as aforesaid, Lessor may (but without being required to do so) pay such
lien or claim and any costs associated therewith, and the amount so paid,
together with interest at the default Interest Rate, as defined hereinafter, and
reasonable attorneys' fees incurred in connection therewith, shall be
immediately due from Lessee to Lessor as additional rent.

                          10.  REPAIRS AND MAINTENANCE
                               -----------------------

          Lessee agrees to pay, as Additional Rent, all costs incurred in
keeping the Building, including all exterior areas, in good order, condition and
repair in accordance with the standards prevailing for a first-class office
building in the Colorado Springs area.

          (1) Notwithstanding any other provisions of this Lease, Lessee shall
pay all costs and expenses of repairing and maintaining in a first-class
condition all portions of the Building (including exterior areas), including,
without limiting the generality of the foregoing, the structural portions of the
Building, the elevators, plumbing, air conditioning, heating and electrical
systems.  Except in the event of an emergency, Lessee shall have the right to
approve in advance any single repair expenditure in excess of $5,000.00, which
approval shall not be unreasonably withheld or delayed.  If Lessee does not
object to any such repair expenditure in a writing delivered to Lessor within
five (5) business days after Lessor's delivery of written notice to Lessee
requesting approval of the expenditure, Lessee's approval shall be deemed to
have been given.  Lessee shall also pay all costs to maintain and keep in good
order and repair the Building roof; all exterior doors, the Building ventilating
systems; elevators; escalators; Building telephone and electrical closets;
public portions of the Building or Building complex, including but not limited
to the balconies, landscaping, walkways, and upper floor lobbies and corridors,
and interior portions of the Building above and below grade; the interior
surfaces of the ceilings, walls and floors, all doors, interior glass partitions
or glass surfaces and pipes, electrical wiring, switches and fixtures; common
areas; and parking areas.

          (2) Lessor shall have the right to do such acts and expend such funds
at the expense of Lessee as are reasonably required to perform such work in
order the maintain the Building in such condition.  Lessor shall have no
liability to Lessee for any damage, inconvenience or interference with the use
of the Premises by Lessee as a result of performing any such work.

          (3) Lessee shall do all acts required to comply with all applicable
laws, ordinances, regulations and rules of any public authority relating to its
occupancy of the Building.

          Notwithstanding the foregoing, Lessee owns and shall be responsible
for the maintenance and repair of the R & D Systems and Prudential signs;
provided that Lessee agrees that it will not

                                       10
<PAGE>
 
remove the Prudential sign without the prior written consent of Lessor so long
as Prudential is a tenant of the Building.

                         11.  ASSIGNMENT AND SUBLETTING
                              -------------------------

          Lessee shall not assign this Lease or any right hereunder or sublet
the Leased Premises or any part thereof, nor permit any persons other than
Lessee and its employees to operate in said Leased Premises without the prior
written consent of Lessor, which consent shall not be unreasonably withheld.  A
consent to any assignment of this Lease or any subletting of said Leased
Premises shall not constitute a waiver or discharge of the provisions of this
paragraph with respect to a subsequent assignment or subletting.

          All subleases shall be in writing and Lessee shall provide copies of
all subleases to Lessor within thirty (30) days of execution thereof.  All
subleases shall be in a form approved by Lessor.  Further, all subleases shall
contain an express provision providing that if an event of default by Lessee
exists under this Lease, then upon notice thereof to the subtenant from Lessor,
all rentals payable by the subtenant shall be paid directly to Lessor, for
Lessee's account, until subsequent notice from Lessor that such event of default
has been cured.  Notwithstanding the foregoing, receipt by Lessor of rent
directly from the subtenant shall not be considered a waiver of such event of
default by Lessee nor an acceptance of such subtenant.

          In the event of any Transfer of this Lease of all or any part of the
Premises by Lessee without the prior written consent of Lessor, Lessor, in
addition to any rights arising upon a default by Lessee, shall have the right to
re-enter and take possession of the Premises or the part thereof subject to such
Transfer, and to enforce all rights of Lessee, and receive and collect all rents
and other payments due to Lessee, in accordance with such sublet or assignment
of the Premises, or any part thereof, as if Lessor was the sublessor or
assignor, and to do whatever Lessee is permitted to do pursuant to the terms of
such sublease or assignment.

          Within ten (10) days after the sale of a majority of the stock of
Lessee or merger of Lessee with another entity, Lessee shall deliver to Lessor
certified financial statements of the purchaser and newly established entity.
If Lessor determines, in its reasonable discretion, that the financial condition
of the Lessee is materially and adversely affected by such transaction, such
stock transfer or merger shall be deemed a default under this Lease.

          At the time of making a request for Lessor's consent to a Transfer and
not less than thirty (30) days prior to the proposed effective date thereof,
Lessee shall provide to Lessor such information as Lessor, its accountants and
attorneys, shall reasonably require with respect to such proposed Transfer,
including but not limited to name and address of the proposed transferee,
description of business operations, financial information and certificate of
corporate authority and good standing or partnership certificates, as
applicable.

          Consent of Lessor to a Transfer shall not relieve Lessee from seeking
consent to any subsequent Transfers.

          Subletting or assignments by subtenants or assignees shall not be
permitted under any circumstances, nor shall Lessee be permitted to assign this
Lease or subject all or any part of the 

                                       11
<PAGE>
 
Premises during any period of time that all or any portion of the Base Rent is
abated. Further, no option to renew or extend the term of this Lease or to lease
additional space, if any, shall be exercisable by any subtenant or assignee.

          All subleases, assignments, and modifications shall be in writing and
a copy thereof provided to Lessor within ten (10) days of its effective date.
All subleases shall further contain an express provision that in the event of
any default by Lessee under this Lease and upon notice thereof to the subtenant
from Lessor, all rentals payable by the subtenant shall be paid directly to
Lessor, for the Lessee's account, until subsequent notice from Lessor that such
default has been cured.  Notwithstanding the foregoing, receipt by Lessor or
rent directly from the subtenant shall not be considered a waiver of the default
on the part of Lessee, nor an acceptance of such subtenant.

          In the event a sublease or assignment is made as herein provided,
Lessee shall pay Lessor a charge of Two Hundred Fifty and no/100 Dollars
($250.00) in order to reimburse Lessor for all of the necessary legal and
accounting services required in order to accomplish such assignment or
subletting.

          The provisions of this Article 11 shall not be applicable with respect
to the two existing leases on the Property and any modifications thereof which
are not in conflict with the terms of this Lease and do not extend the term of
such lease beyond the term of this Lease, which are deemed approved by Lessor,
provided that any other modifications of such leases shall be subject to the
terms hereof.

                       12.   ASSIGNMENT OR SALE BY LESSOR
                             ----------------------------

          In the event Lessor shall assign this Lease and/or sell or convey the
Building, the same shall operate to release Lessor from any future liability
upon any of the covenants or conditions, express or implied, herein contained in
favor of Lessee, and in such event Lessee agrees to look solely to the successor
in interest of Lessor in and to this Lease.  This Lease shall not be affected by
such assignment or sale, and Lessee agrees to attorn to the purchaser or
assignee.

                       13.  INJURY TO PERSON OR PROPERTY
                            ----------------------------

          Lessee agrees that Lessor, its agents and employees will not be liable
for any loss, injury, death, or damage (including consequential damages) to
persons, property, or Lessee's business occasioned by theft, act of God, public
enemy, injunction, riot, strike, insurrection, war, court order, requisition,
order of governmental body or authority, or from any acts or omissions of any
other tenant, occupant, or visitor of the premises, or from any cause beyond
Lessor's control.

                           14.   INDEMNITY TO LESSOR
                                 -------------------

          Lessee will indemnify Lessor, its agents, and employees against, and
hold Lessor, its agents, and employees harmless from, any and all demands,
claims, causes of action, fines, penalties, damages (including consequential
damages), losses, liabilities, judgments, and expenses (including without
limitation attorneys' fees and court costs) incurred in connection with or
arising from: (a) the use or occupancy of the premises by Lessee or any person
claiming 

                                       12
<PAGE>
 
under Lessee; (b) any acts, omissions, or negligence of Lessee or any person
claiming under Lessee or the employees, agents, contractors, invitees, or
visitors of Lessee or any such person; (c) any breach, violation, or
nonperformance by tenant or any person claiming under Lessee or the employees,
agents, contractors, invitees, or visitors of Lessee or any such person or any
term, covenant, or provision of this Lease or any law, ordinance, or
governmental requirements of any kind; or (d) (except for loss of use of all or
any portion of the premises or Lessee's property located within the leased
Premises that is proximately caused by or results proximately from the
negligence of Lessor), any injury or damage to the person, property, or business
of Lessee, its employees, agents, contractors, invitees, visitors, or any other
person entering upon the premises under the express or implied invitation of
Lessee. If any action or proceeding is brought against Lessor, its employees, or
agents by reason of any such claim, Lessee upon notice from Lessor, will defend
the claim at Lessee's expense.

                           15.  ESTOPPEL CERTIFICATE
                                --------------------

          Lessee agrees that from time to time upon not less than ten (10)
business days prior written request by Lessor, Lessee (or any permitted
assignee, sublessee, licensee, concessionee or other occupant of the Premises
claiming by, through or under Lessee) will deliver to Lessor, a statement in
writing signed by Lessee certifying (a) that this Lease is unmodified and in
full force and effect (or if there have been modifications, that this Lease as
modified is in full force and effect and identifying the modifications); (b) the
dates to which the rent and other charges have been paid; (c) that Lessor is not
in default under any provision of this Lease, or, if in default, the nature
thereof in detail; (d) that Lessee is in occupancy and paying rent on a current
basis with no rental offsets or claims; (e) that there has been no prepayment of
rent other than that provided for in this Lease; (f) that there are no actions,
whether voluntary or otherwise, pending against Lessee under the bankruptcy laws
of the United States or any State thereof, and (g) such other matters as may be
required by a prospective purchaser or lender of the Building.  Lessee's failure
to deliver such a statement within ten (10) days of the request by Lessor shall
be conclusive upon Lessee that this Lease is in full force and effect, without
modification except as may be represented by Lessor, that there are no uncured
defaults in Lessor's performance and that not more than one month's rental has
been paid in advance.  Lessee hereby appoints Lessor as attorney-in-fact for
Lessee with full power and authority to execute and deliver in the name of
Lessee any such certificate in the event Lessee fails to do so on request.

                           16.   SURRENDER AND NOTICE
                                 --------------------

          Lessee agrees to surrender and deliver possession of the Leased
Premises promptly at the expiration of this Lease, or in the case of the
termination of this Lease by Lessor by reason of a breach in any one or more of
the covenants or agreements hereof, in accordance with the laws of the State of
Colorado and any court order pertaining thereto.  This lease shall be construed
and governed by the laws of the State of Colorado.

                     17.   ACCEPTANCE OF PREMISES BY LESSEE
                           --------------------------------

          Lessor and Lessee agree that the possession of the Building by Lessee
shall be conclusive evidence as against Lessee that said Premises are in good
and satisfactory condition when possession was taken.

                                       13
<PAGE>
 
                      18.   FIRE, RESTORATION OF PREMISES
                            -----------------------------

          Lessor and Lessee agree that if the Leased Premises, or the Building
shall be so damaged by fire or other casualty as to render the Leased Premises
wholly untenantable, and if such damage shall be so great that a competent
architect, in good standing and selected by Lessor, shall certify in writing to
Lessor and Lessee that the Leased Premises, with the exercise of reasonable
diligence, cannot be made fit for occupancy within ninety (90) days from the
happening thereof, then this Lease shall cease and terminate from the date of
the occurrence of such damage at the sole option of Lessor; and Lessee thereupon
shall surrender to Lessor the Leased Premises and all interest therein
hereunder, and Lessor may reenter and take possession of the Leased Premises and
remove Lessee therefrom.  Lessee shall pay rent, duly apportioned, up to the
time of such damage.

          If, however, the damage shall be such that said architect shall
certify that the Leased Premises can be made tenantable within said ninety (90)
day period from the happening of such damage, then Lessor shall repair the
damage so done with all reasonable speed and the rent shall be abated only for
the period during which Lessee shall be deprived of the use of the Leased
Premises by reason of such damage and the repair thereof.

          If the Leased Premises, without the fault of Lessee, shall be slightly
damaged by fire or other casualty, but not so as to render the same untenantable
Lessor shall cause the same to be repaired with reasonable promptness.

          In case the Building throughout be so damaged, whether by fire or
otherwise (though said Leased Premises may not be affected) that Lessor within
sixty (60) days after the happening of such damage shall decide to reconstruct,
rebuild, or raze the Building, then upon thirty (30) days' notice in writing to
that effect given by Lessor to Lessee, this Lease shall cease and terminate from
the date of the occurrence of said damage, and Lessee shall pay the rent,
properly apportioned up to such date, and both parties hereto shall be
discharged of all further obligations hereunder.

                   19.   EMINENT DOMAIN, TERMINATION OF LEASE
                         ------------------------------------

          If the Leased Premises or such portion thereof as shall render the
remaining portion unusable by the Lessee for its intended purpose shall be taken
by right of eminent domain, then this Lease, at the option of Lessor, shall
forthwith cease and terminate, and the current rent shall be properly
apportioned to the date of such taking; and in such event Lessor shall receive
the entire award for the lands and improvements so taken.  Notwithstanding the
foregoing, Lessee shall have the right to make its own claim for damages caused
by the taking and receive the award pertaining to such claim.

                        20.   DEFAULT--EVENTS OF DEFAULT
                              --------------------------

          The following occurrences are "events of default":

                                       14
<PAGE>
 
          (1) Lessee defaults in the due and punctual payment of rent, and the
default continues for five (5) business days after notice from Lessor;

                    (a) Lessee vacates or abandons the Premises;

                    (b) This lease or the Premises or any part of the Premises
are taken upon execution or by other process of law directed against Lessee, or
are taken upon or subjected to any attachment by any creditor of Lessee or
claimant against Lessee, and the attachment is not discharged within fifteen
(15) days after its levy;

                    (c) Lessee files a petition in bankruptcy or insolvency or
for reorganization or arrangement under the bankruptcy laws of the United States
or under any insolvency act of any state, or is dissolved, or makes an
assignment for the benefit of creditors;

                    (d) Involuntary proceedings under any bankruptcy laws or
insolvency act or for the dissolution of Lessee are instituted against Lessee,
or a receiver or trustee is appointed for all or substantially all of Lessee's
property, and the proceeding is not dismissed or the receivership or trusteeship
is not vacated within sixty (60) days after the institution or appointment;

                    (e) Lessee fails to take possession of the Premises on the
commencement date of the term; or

                    (f) Lessee breaches any of the other agreements, terms,
covenants, or conditions that this Lease requires Lessee to perform, and the
breach continues for a period of thirty (30) days after notice by Lessor to
Lessee, or such longer period as may be necessary to cure such breach, so long
as Lessee continuously and diligently works to cure the breach.

                       21.  DEFAULTS BY LESSEE
                            ------------------

          (1) If Lessee at any time is in default with respect to any rental
payments or other charges payable by Lessee, and if the default continues for a
period of 5 business days after written notice from Lessor to Lessee; or if
Lessee is in default in the prompt and full performance of any other of its
promises, covenants, or agreements contained in this Lease, and if the default
or breach of performance continues for more than a reasonable time (in no event
to exceed 30 days) after written notice from Lessor to Lessee specifying the
particulars of such default or breach of performance; or if Lessee vacates or
abandons the Premises, Lessor may treat the occurrence of any one or more of the
foregoing events as a breach of this Lease, and in addition to any or all other
rights or remedies of Lessor by law, Lessor may, at the option of Lessor,
without further notice or demand of any kind to Lessee or any other person:

                    (a) Declare the term ended, reenter the Premises, take
possession of the Premises, and remove all persons from the Premises; or

                    (b) Without declaring this lease terminated, reenter the
Premises, occupy the whole or any part of the Premises for and on account of
Lessee, and collect any
                                       15
<PAGE>
 
unpaid rentals and other charges which have become payable or which may
thereafter become payable; or

                   (c) Even though it may have reentered the Premises, elect to
terminate this Lease and all of the rights of Lessee in or to the Premises.

          If Lessor has reentered the Premises under the provisions of
subparagraph (b) above, Lessor will not be deemed to have terminated this lease,
or the liability of Lessee to pay any rental or other charges accruing after
Lessor's entry, or to have terminated Lessee's liability for damages under any
of the provisions of this lease, by any reentry or by any action, in unlawful
detainer or otherwise, to obtain possession of the Premises, unless Lessor has
notified Lessee in writing that it has elected to terminate this lease.  Lessee
further covenants that the service by Lessor of any notice pursuant to the
unlawful detainer statutes of the state where the shopping center is situated
and the surrender of possession pursuant to such notice will not (unless Lessor
elects to the contrary at the time of or at any time subsequent to the serving
of such notices and such election is evidenced by a written notice to Lessee) be
deemed to be a termination of this lease.  In the event of any entry or taking
possession of the Premises, Lessor will have the right, but not the obligation,
to remove all or any part of the personal property located in them and may place
it in storage at a public warehouse at the expense and risk of Lessee.

          (2)  If Lessor elects to terminate this Lease pursuant to the
provisions of subparagraph (a) or (c) above, Lessor may recover from Lessee as
damages:

                   (a) The worth at the time of award of any unpaid rental that
had been earned at the time of termination;

                   (b) The worth at the time of award of the amount by which the
unpaid rental that would have been earned after termination until the time of
award exceeds the amount of such rental loss Lessee proves could have been
reasonably avoided; plus

                   (c) The worth at the time of award of the amount by which the
unpaid rental for the balance of the term after the time of award exceeds the
amount of such rental loss Lessee proves could be reasonably avoided; plus

                   (d) Any other amount necessary to compensate Lessor for all
the detriment proximately caused by Lessee's failure to perform its obligations
under this lease or which in the ordinary course of things would be likely to
result from Lessee's failure, including, but not limited to, any costs or
expenses incurred by Lessor in retaking possession of the Premises, including
reasonable attorneys' fees; maintaining or preserving the Premises after such
default; preparing the Premises for reletting to a new Lessee, including repairs
or alterations to the Premises for such reletting; leasing commissions; or any
other costs necessary or appropriate to relet the Premises.

          As used in subparagraphs (a) and (b), the "worth at the time of award"
is computed by allowing interest at the maximum lawful rate but in no event
greater than 18% per annum.  As used in subparagraph (c), the "worth at the time
of award" is computed by discounting such 

                                       16
<PAGE>
 
amount at the discount rate of the Federal Reserve Bank situated nearest to the
location of the Premises at the time of award plus 1%.

          The term "rental" will be deemed to be the minimum annual rental and
all other sums required to be paid by Lessee pursuant to the terms of this
lease.  All such sums, other than the minimum annual rental, will, for the
purpose of calculating any amount due under the provisions of subparagraph (c),
be computed on the basis of the average monthly amount accruing during the
immediately preceding 60-month period, except that if it becomes necessary to
compute the rental before such a 60-month period has elapsed then the rental
will be computed on the basis of the average monthly amount accruing during the
shorter period.

          Notwithstanding any other provisions of this paragraph, Lessor agrees
that if the default complained of, other than for the payment of monies, is of
such a nature that it cannot be cured within the period requiring such curing as
specified in the written notice relating to it, then the default will be deemed
to be cured if Lessee, within such period, has commenced the curing and
continues with all due diligence to cause the curing and completes the curing
with the use of such diligence.

          The rights and remedies given to Lessor in this paragraph will be in
addition and supplemental to all other rights or remedies that Lessor may have
under laws then in force.

                           22.   REMEDIES UPON BREACH
                                 --------------------

          Any rents or other amounts owing to Lessor hereunder which are not
paid within ten (10) business days of the date they are due, shall thereafter
bear interest from the due date at the rate of eighteen percent (18%) per annum
("Interest Rate") until paid.  Similarly, any amounts paid by Lessor to cure an
default of Lessee or to perform any obligation of Lessee, shall bear interest
from the date paid by Lessor at the Interest Rate until paid.  In addition to
the foregoing, Lessee shall pay to Lessor whenever any Base Rent, Additional
Rent or any other sums due hereunder remain unpaid more than ten (10) days
after the due date thereof, a late charge equal to ten percent (10%) of the
amount due.  Further, in the event of default by Lessee, in addition to all
other rights and remedies, Lessor shall be entitled to receive from Lessee all
sums, the payment of which may previously have been waived or abated by Lessor,
or which may have been paid by Lessor pursuant to any agreement to grant Lessee
a rental abatement or the monetary inducement or allowance or moving allowance,
together with interest thereon from the date or dates such amounts were paid by
Lessor or would have been due from Lessee but for the abatement, at the Interest
Rate, until paid; it being understood and agreed that such concession or
abatement was made on the condition and basis that Lessee fully perform all
obligations and covenants under the Lease for the entire term.

             23.   PREMISES LEFT VACANT--LESSOR MAY TAKE POSSESSION
                   ------------------------------------------------

          Lessor and Lessee agree that if Lessee shall abandon or vacate the
Leased Premises before the end of the term of this Lease, Lessor may, at its
option and without notice, and using such force as may be necessary, enter the
Leased Premises, remove any signs of Lessee therefrom, and relet the same, or
any part thereof, as Lessor may see fit for the account of Lessee, without
thereby voiding or terminating this Lease, and, for the purpose of such
reletting, Lessor 

                                       17
<PAGE>
 
is authorized to make any repairs, changes, alterations or additions in or to
the Leased Premises, as may in the opinion of Lessor, be necessary or desirable
for the purpose of such reletting, and if a sufficient sum shall not be realized
from such reletting (after payment of all the costs and expenses of such
repairs, changes or alterations, and the expense of such reletting and the
collection of rent accruing therefrom) to equal the aggregate monthly rental
agreed for the balance of this Lease Term or for any renewal period to be paid
by Lessee under the provisions of this Lease, then Lessee agrees to pay such
total deficiency upon demand therefore, and if no other rental can be obtained
after reasonable effort by Lessor for a period of sixty (60) days after Lessee's
breach as contemplated herein, then Lessee shall be liable for the total rental
due for the balance of the period from the date of such default.

                       24.  REMOVAL OF LESSEE'S PROPERTY
                            ----------------------------

          Lessor and Lessee agree that if Lessee shall fail to remove all
effects from the Leased Premises upon the abandonment thereof or upon the
termination of this Lease for any cause whatsoever, Lessor, at its option, may
remove such effects in any manner that it shall choose, and store them without
liability to Lessor for loss or damage thereof, and Lessee agrees to pay Lessor
on demand any and all expenses incurred in such removal, including court costs
and attorney's fees and storage charges on such effects for any length of time
they shall be in Lessor's possession; and/or Lessor, at its option, without
notice, may sell said effects, or any of them, at private sale and without legal
process, for such prices as Lessor may obtain, and apply the proceeds of such
sale upon any amounts due under this Lease from Lessee to Lessor and upon the
expense incident to the removal and sale of said effects, rendering the surplus,
if any, to Lessee.

                25.  CONSTRUCTIVE EVICTION--NOTICE REQUIREMENT
                     -----------------------------------------

          If Lessee believes that Lessor has or is committing an act or acts
which constitute constructive eviction, Lessee must provide Lessor with written
notice specifying the act or acts which allegedly constitute a constructive
eviction, and Lessor shall have ten (10) days from the receipt of said notice to
cure the alleged constructive eviction.  Lessee shall not exercise his legal
rights to assert a constructive eviction until Lessor's ten (10) day cure period
has expired, and Lessee shall be deemed to have conclusively waived its rights
to assert a constructive eviction if it abandons the Premises before the cure
period has expired.

                      26.  NO IMPLIED SURRENDER OR WAIVER
                           ------------------------------

          Lessor and Lessee agree that no act or thing done by Lessor or its
agents during the term of this Lease shall be deemed an acceptance of a
surrender of the Leased Premises, and no agreement to accept a surrender of the
Leased Premises shall be valid, unless the same be made in writing and
subscribed by Lessor.  The mention in this Lease of any particular remedy shall
not preclude Lessor from any other remedy Lessor might have, either in law or in
equity, nor shall the waiver of any violation of any covenant or condition
contained in this Lease or any of the rules and regulations set forth herein, or
hereafter adopted by Lessor, prevent a subsequent act, which would have
originally constituted a violation, from having all the force and effect of any
original violation.

                           27.   COSTS OF CONVERSION
                                 -------------------

          In case it should be necessary or proper for Lessor to bring any
action under this Lease or to place this Lease with an attorney for the
enforcement of any of Lessor's rights hereunder, then Lessee agrees in each and
any such case to reimburse Lessor for Lessor's reasonable attorney's fees and
legal expenses, including, but not limited to, direct in-house legal expenses.

                                  28.   WAIVER
                                        ------

          The receipt by Lessor of rent with knowledge of the breach of any
covenant in this Lease, shall not be deemed a waiver of such breach.  The
failure to enforce any of the rules and regulations set forth herein, or
hereafter adopted, against Lessee and/or any other Lessee in the Building shall
not be deemed a waiver of such rules and regulations or any covenant thereof.
The receipt by Lessor of rent from any assignee, subtenant, or occupant of the
Leased Premises shall not be deemed a waiver of the covenant contained in this
Lease against assignment and subletting, or an acceptance of the assignee,
subtenant or occupant as Lessee, or a release of Lessee from the further
observance or performance by Lessee of the covenants in this Lease to be
observed and performed by the Lessee. No provisions of this Lease shall be
deemed to have been waived by Lessor unless such waiver be in writing and signed
by Lessor.

                   29.   HOLDING OVER--TENANCY MONTH TO MONTH
                         ------------------------------------

          Lessor and Lessee agree that if after the expiration of this Lease,
Lessee shall remain in possession of the Leased Premises and continue to pay
rent and without any express agreement as to such holding over, then such
holding over shall be deemed to be a tenancy from month-to-month, and Lessee
shall be regarded as a Lessee from month-to-month, subject to all the terms and
conditions of this Lease, except that the base monthly rental rate for any such
holdover period shall be an amount equal to one and one half (1-1/2) times the
last base monthly rental amount.

                        30.   PAYMENTS AFTER TERMINATION
                              --------------------------

          Lessor and Lessee agree that no payments of money by Lessee to Lessor
after the termination of this Lease, in any manner, or after the giving of any
notice (other than a demand for payment of money) by Lessor to Lessee, shall
reinstate, continue or extend the term of this Lease or affect any notice given
to Lessee prior to the payment of such money, it being agreed that after the
service of notice or the commencement of a suit or after final judgment granting
Lessor possession of the Leased Premises, Lessor may receive and collect any
sums of rent due, or any other sums of money due under the terms of this Lease,
and the payment of such sums of money, whether as rent or otherwise, shall not
waive said notice, or in any manner affect any pending suit or any judgment
theretofore obtained.


                    31.   COMPLETION OF THE LEASED PREMISES
                          ---------------------------------

          It is mutually understood and agreed that anything to the contrary or
apparent contrary herein, Lessee has occupied the Leased Premises for several
years and that its continued 

                                       19
<PAGE>
 
occupancy of the Leased Premises shall be conclusive evidence as against Lessee
that the Leased Premises are complete and satisfactory whether all of the
Building and tenant spaces shall be completed or not.

                                 32.   NOTICE
                                       ------

          Any notice to be given to Lessor as provided for in this Lease shall
be delivered in writing in person, or by certified mail to Robert Spade, 121 E.
Pikes Peak Avenue, Suite 335, Colorado Springs, Colorado 80903; with a copy to
Richard Nipert, Bright, Gibson & Nipert, P.C., 1140 Grant Street, Suite 100,
Denver, Colorado 80203.  Any notice to be given Lessee under the terms and
provisions of this Lease shall be in writing and may be given in person or by

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

          (1) The "common area" of the property is that part of the property
designated by Lessor from time to time for the common use of all tenants
including, among other facilities, parking areas, sidewalks, landscaping, curbs,
truckways, delivery passages, loading area, private street and alleys, and
lighting facilities and certain common areas provided for the common use of
parties in the Plumtree complex pursuant to the Declaration of Covenants for
Plumtree Center, as the same may be amended from time to time.  Lessor reserves
the right to change from time to time the dimensions and location of the common
areas as well as the dimension, identity and type of any buildings (except the
Leased Premises) on the property and to construct additional buildings or
additional stories on existing buildings or other improvements on the property
(except the Leased Premises) for street, park, utility and other public
purposes.  Lessee and its employees, customers, invitees, sublessees,
concessionaires and licensees shall have the non-exclusive right to use the
common area, as constituted from time to time, such use to be in common with
Lessor, other tenants of the property and other persons entitled to use the
same, and subject to the rules and regulations governing use as they may be
amended from time to time, including the designation of specific areas for
automobiles owned by any tenant or subtenant, its employees, sublessees,
concessionaires or licensees.  Lessee shall not take any action which would
interfere with the rights of other persons to use the common area.  Lessor may
temporarily close any part of the common area for such periods of time as may be
necessary to prevent the public from obtaining prescriptive rights or to make
repairs or alterations.

          (2) Lessor will operate and maintain the interior and exterior common
areas associated with the Building.  The costs shall be those of operating and
maintaining the common area in a manner deemed by Lessor reasonable and
appropriate and for the best interests of the property, including, without
limitation: all costs and expense of managing, operating, maintaining,
repairing, lighting, providing janitorial service, cleaning, painting, striping,
policing, insuring, providing utilities, removing snow, ice and debris;
efficiency studies (if approved in Lessee's reasonable discretion) and
regulating traffic; costs and expenses, if any, of heating the common areas;
costs and expenses of inspection maintenance, and depreciation of machinery and
equipment used in the operation and maintenance of the common facilities,
including, if any, the common area heating equipment, and personal property
taxes and other charges incurred in connection with such equipment; costs and
expenses of maintaining, planting, replanting, and 

                                       20
<PAGE>
 
replacing flowers and shrubbery and planters and other landscaping; real estate
taxes and special assessments applicable to common area and land underlying
same; sprinkler maintenance costs; and administrative cost of operating and
maintaining the common area. Such costs and expenses shall not include
depreciation (other than depreciation above specified). The costs of operating
and maintaining the common areas shall also include the costs assessed to the
Building pursuant to the Declaration of Covenants of Plumtree Center, as the
same may be amended from time to time.

          (3) Lessee shall pay Lessor, as Additional Rent, the costs of
operating and maintaining the common areas on a monthly basis on the same date
Base Rent is due.

          (4) The charge required hereunder shall be paid by Lessee in twelve
(12) monthly installments in such amounts as are estimated by Lessor at the
beginning of a twelve (12) month period commencing and ending on dates
designated by Lessor, each such installment being due on the first day of each
month.  The monthly payments to be made by Lessor shall be adjusted and revised
to compensate for any overpayment or underpayment made by Lessee in such
preceding twelve (12) month period.  Within ninety (90) days after the end of
each twelve (12) month period, Lessor shall make available Lessor's records
related to Lessor's operating cost for such preceding twelve (12) month period.

                          34.   RULES AND REGULATIONS

any other defaults herein:

<PAGE>
 
approved by Lessor as to color, size, style and location; but there shall be no
obligation or duty on Lessor to allow any additional sign, advertisement or
notice to be inscribed, painted or affixed on any part of the inside or outside
of the Leased Premises or of the Building. A directory in a conspicuous place,
with the name of Lessee, will be provided by Lessor, with the original building
standard directory strips being paid for by Lessor. Any necessary revision in
the building standard suite sign and directory strip, will be made by Lessee
within a reasonable time after notice of the error or change making the revision
necessary; such revisions being at the sole expense of Lessee. No furniture
shall be placed in front of the Building or in any lobby or corridor without the
prior written consent of Lessor. Lessor shall have the right to remove all non-
permitted signs and furniture, without notice to Lessee, at the expense of
Lessee.

          (4)  Lessee shall not do or permit anything to be done in the Leased
Premises, or bring or keep anything therein, which will in any way increase the
cost of fire insurance for the Building, or on property kept therein, or in any
way injure or annoy other occupants or their guests, or conflict with the laws
relating to fire, or with any regulations of the fire department, or with any
insurance policy upon the Building or any part thereof, or conflict with any
applicable fire or health law, statute, regulation or ordinance.

back or wedging the faucets in any manner.

          (7)  No animals, except handicapped assistance animals, shall be

the use of any radio or musical instrument or by the making of loud or improper
noises.

          (8)  Bicycles or other vehicles shall not be permitted in the offices,
halls, corridors and elevators in the Building, nor shall any obstruction of
sidewalks or entrances of the Building be permitted.  Bicycles shall not be
locked to trees, downspout, signs or other portions of the Building or
surrounding Premises.

          (9)  Lessee shall not allow anything to be placed in the outside
window ledges of the Building, nor shall anything be thrown by Lessee, its
agents or employees, out of the windows or doors, or down the halls, elevator
shafts or ventilating ducts or shafts of the Building. Lessee, except in the
case of fire or other emergency, shall not open any outside window as this
interferes with the proper functioning of the Building air conditioning system.

          (10) No additional lock or locks or security system shall be placed by
Lessee on any door in the Building unless written consent of Lessor shall first
have been obtained, which consent shall not be unreasonably withheld.  A master
key to all areas of the Leased Premises and to the toilet rooms will be
furnished by Lessee to Lessor.  A reasonable charge for extra keys will 

                                       22
<PAGE>
 
be made to Lessee. At the termination of this tenancy, Lessee shall promptly

          (11) No awnings shall be placed over the windows except by the prior
written consent of Lessor.  No inside screening, draping, shades or blinds shall
be hung on or over the windows except by the prior written consent of Lessor.

          (12) Whenever heat generating machines or equipment, including
telephone equipment, are used in the Leased Premises, and such machines or
equipment affect the temperature otherwise maintained by the air conditioning

operation and maintenance of such supplemental air conditioning, shall be paid
by Lessee upon demand by Lessor.

          (13) Lessee shall not install or operate any steam or gas engine or

in accordance with law and are customarily used by dentists in their practice.

          (14) Any painting or decorating as may be agreed to be done by, and at
the expense of Lessor, shall be done during regular working hours; should Lessee
desire such work done on Sundays, holidays or outside of regular working hours,

          (15) Except normal picture hanging and except as otherwise permitted
by Lessor, Lessee shall not mark upon, paint signs upon, cut, drill into, drive

injury caused by Lessee, its agents or employees shall be paid for by Lessee.

          (16) Lessor shall at all times have the right, by its officers or

days prior to the termination of this lease, place upon the doors and windows of
the Leased Premises the notice "For Rent", which notice shall not be removed by
Lessee.

          (17) Lessor reserves the right to make other reasonable rules and
regulations, or amend these rules and regulations, as Lessor's judgment may from
time to time be necessary and desirable for the safety, care and cleanliness of
the Leased Premises, and for the preservation of good order thereof, provided
that no such new rules and regulations shall materially and adversely alter
Lessee's rights under this Lease.

          (18) No storing of vehicles shall be permitted.

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

          Lessor and Lessee agree that this Lease is subject to, and subordinate
to, all ground or underlying leases and to all present mortgages affecting the
real estate on which the Building is located and the Building of which the
Leased Premises is a part, and to all renewals and extensions thereof, and to
any mortgage or mortgages which may hereafter be executed affecting the same.

                        36.   AMENDMENT OR MODIFICATION
                              -------------------------

          Lessee acknowledges and agrees that it has not relied upon any
statement, representation, agreement or warranty except such as is expressed
herein, and that no amendment or modification to this Lease shall be valid or
binding unless expressed in writing and executed by Lessor and Lessee in the
same manner as in the execution of this Lease.

                           37.   SEVERABILITY CLAUSE
                                 -------------------

          If any clause or provision of this Lease is illegal, invalid or
unenforceable under present or future laws effective during the term of this
Lease, then and in that event, it is the intention of Lessor and Lessee that
the remainder of this Lease shall not be affected thereby, and it is also the
intention of Lessor and Lessee that in lieu of each clause or provision of this
Lease that is illegal, invalid or unenforceable there be added as a part of this
Lease a clause or provision as similar in terms to such illegal, invalid or
unenforceable clause or provision as may be possible and be legal, valid and
enforceable.  The caption of each paragraph hereof is added as a matter of
convenience only and shall be considered to be of no effect in the construction
of any provision or provisions of this Lease.

                          38.  SUCCESSORS AND ASSIGNS
                               ----------------------

          It is expressly understood that Lessor and Lessee are not partners or
joint venturers and the Lessor has no right, title or interest in and to the
business of Lessee, and that Lessor has no right to represent or bind Lessee in
any respect whatsoever and that nothing herein contained shall be deemed, held
or construed as making Lessor a partner, joint venturer, or associates of
Lessee, nor as rendering Lessor liable for any debts, liabilities or obligations
incurred by Lessee.  Neither is the relationship between Lessor and Lessee that
of principal and agent.  It is expressly understood that the relationship
between the parties hereto is and shall at all times remain, that of Lessor and
Lessee.

                                       --------

          Where there is an Addendum to this Lease, if there are any conflicts
between the provisions of the Addendum and the provisions of this Lease, the
provisions of the Addendum shall control.

                                       -------

          Lessee warrants that it has not dealt with any real estate broker or
agent in connection with the negotiation of this Lease to whom a real estate
commission might be due, or who might have an interest in this transaction.

          Lessee agrees to indemnify and hold harmless Lessor and the Manager
from and against any and all liabilities and claims for commissions and fees
arising out of a breach of the foregoing representation.  Lessor shall be
responsible for the payment of all commissions to the broker, if any, specified
in this Article, based upon the leasing commission policy of Lessor applicable
to the Complex as of the date of this Lease.

                              42.   LEGAL COUNSEL
                                    -------------

          No representation or recommendation is made by the real estate broker
or its agents or employees as to the legal sufficiency, legal effect, or tax
consequences of this Lease, or the transactions relating thereto.  It is
recommended that the Lessee employ an attorney prior to executing this Lease to
review the Lease and provide legal counsel.

                             43.   OPTION TO RENEW
                                   ---------------

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

          Lessor's liability under this Lease shall be limited to Lessor's
estate and interest in the Building (or to the proceeds thereof) and no other
property or other assets of Lessor or its partners (if Lessor is a partnership),
agents, employees, legal representatives, successors or assigns, shall be
subject to levy, execution or other enforcement procedure for the satisfaction
of Lessee's remedies under or with respect to this Lease, the relationship of
Lessor and Lessee hereunder or Lessee's use and occupancy of the Premises.
Nothing contained in this Paragraph shall be construed to permit Lessee to
offset against rents due a successor landlord, a judgment (or other judicial
process) requiring the payment of money by reason of any default of a prior
landlord, except as otherwise specifically set forth herein.

                             45.   PRIOR TENANCIES
                                   ---------------

          Lessee understands and acknowledges that portions of the building are
subject to the prior tenancies of Jeff M. Rayl, D.D.S. and Kathleen Rayl, and
Prudential Insurance Company of America, and that this Lease is subject to the
rights of said tenants.  Notwithstanding the 

                                       25
<PAGE>
 
foregoing, upon commencement of this Lease term, the provisions hereof shall act
as and constitute an assignment to and acceptance by Lessee of all of Lessor's
right, title and interest with respect to the foregoing tenancies. More
specifically, Lessee shall be entitled to receive all rental payments payable by
said tenants accruing during the term of this Lease and Lessee shall be
obligated to perform all covenants and obligations on the part of the Lessor
with respect to said tenancies. In furtherance of the foregoing, Lessor agrees
to execute all documents in form mutually acceptable to Lessor and Lessee
reasonably necessary to effectuate the foregoing and shall execute any and all
notices to said tenants in form mutually acceptable to Lessor and Lessee
reasonably requested by Lessee with respect to effectuating the foregoing.

                              46.   FORCE MAJEURE
                                    -------------

          In the event that either party shall be delayed or hindered in or
prevented from the performance of any act required hereunder by reason of
strikes, riots, insurrection, or war, then performance of such act shall be
excused from the period of the delay and the period from the performance of any
such act shall be extended for a period equivalent to the period of such delay.
The provisions of this section shall not operate to excuse Lessee from prompt
payment of rents or any other payments required by the terms of this Lease.

                                OPTION TO RENEW

          (a) So long as Lessee is not in default under this Lease, either at
the time of exercise or at the time the extended term commences, Lessee will
have the option to extend the initial four (4) year term of this Lease for an
additional period of either three (3) or five (5) years (the "option period") on
the same terms, covenants, and conditions of this Lease, except that the monthly
rent during the option period will be determined pursuant to the following
paragraph.  Lessee will exercise its option by giving Lessor written notice
("option notice") at least one (1) year prior to the expiration of the initial
term of this Lease, which notice shall include Lessee's election to extend the
term for either three (3) or five (5) years.

          (b) The initial monthly rent for the option period will be determined
as follows:

                 (i) Lessor and Lessee will have fifteen (15) days after Lessor
receives the option notice within which to agree on the then-fair market rental
value of the Premises, and rental increases to the monthly rent for the option
period. If they agree on the initial monthly rent and rental increases for the
option period within fifteen (15) days, they will amend this Lease by stating
the initial monthly rent and rental increases for the option period.

                (ii) The "then-fair market rental value of the Premises" means
what a landlord under no compulsion to lease the Premises and a tenant under no
compulsion to lease the Premises would determine as rents (including initial
monthly rent and rental increases) for the option period, as of the commencement
of the option period, taking into consideration the uses permitted under this
Lease, the quality, size, design, and location of the Premises, and the rent for
comparable buildings located in the vicinity of the Building. The then-fair
market rental value of the Premises and the rental increases in the monthly rent
for the option period will not be less than that provided during the initial
term.

               (iii) Within seven (7) days after the expiration of the fifteen
(15) day period set forth in paragraph (b)(2), the parties will attempt to agree
upon the selection of an appraiser to determine the then-fair market rental
value of the Premises and rent escalators. If the parties cannot agree upon an
appraiser, each party will hire an appraiser with at least five years full-time
commercial appraisal experience in the Colorado Springs area. The then-fair 
market rental value and rent escalators will then be determined by averaging the
rental values and escalators of the two appraisers. The determination of the
appraiser (if one is agreed upon by the parties) or the calculation of the
averages of the two appraisers shall conclusively determine the rental increases
during the renewal term. This rent determination process shall be completed
within ninety (90) days of option notice receipt by Lessor, or Lessor, at its
discretion, may terminate the lease renewal option. This rent determination
process shall be completed within ninety (90) days of receipt of the notice

exercising the option by Lessor, or Lessor, at its discretion, may terminate
this Lease renewal option.

                                      --------  -------
that the Company redeems the Senior Redeemable Preferred Stock issued or
issuable to the Investors (as defined in a certain Stock Purchase Agreement
dated the date hereof by and among the Company, the Investors and certain other

accelerated vesting provided hereunder for such year if the Company achieves
Revenue and Operating Profit levels for the following year which exceed the
relevant Schedule A or Schedule B targets for such following year by amounts
which equal or exceed the amounts by which the Company failed to achieve the
Revenue and Operating Profit targets on that Schedule for the prior year and the
Officer remains an employee of the Company when the audited financial statements
for such following year are delivered. The number of shares set forth in this

         Section 2.  Purchase and Sale of Shares; Investment Representations.
                     -------------------------------------------------------

         (a) Purchase and Sale. On the date hereof and pursuant to the Company's
             -----------------
1996 Stock Option and Grant Plan, the Company hereby sells to the Officer, and
the Officer hereby purchases from the Company, the Shares at a purchase price of
$0.50 per Share payable in cash for an aggregate purchase price of $320,242.50.
The Company and the Officer agree that the aggregate fair market value of the

         (b)  Investment Representations.  In connection with the purchase and 
              --------------------------
sale of the Shares contemplated by Section 2(a) above, the Officer hereby
represents and warrants to the Company as follows:

                (i)      The Officer is purchasing the Shares for his own 
account for investment only, and not for resale or with a view to the
distribution thereof.

                (ii)     The Officer has had such an opportunity as he has 
deemed adequate to obtain from representatives of the Company such information
as is necessary to permit him to evaluate the merits and risks of his investment
in the Company.

                                       2
<PAGE>
 
                (iii)    The Officer has sufficient experience in business,
financial and investment matters to be able to evaluate the risks involved in
the purchase of the Shares and to make an informed investment decision with
respect to such purchase.

                (iv)     The Officer can afford a complete loss of the value of 
the Shares and is able to bear the economic risk of holding such Shares for an
indefinite period.

                (v)      The Officer understands that the Shares are not 
registered under the Act or any applicable state securities or "blue sky" laws
and may not be sold or otherwise transferred or disposed of in the absence of an
effective registration statement under the Act and under any applicable state
securities or "blue sky" laws (or exemptions from the registration requirements
thereof).

         Section 3.  Repurchase Option.
                     -----------------

         3.1. Repurchase Option. In the event of a Termination Event, the 
              -----------------
Company shall have the right and option (the "Repurchase Option") to repurchase
all, but not less than all, of the Non-Vested Shares at a per share repurchase
price equal to the aggregate of (i) $0.50 (adjusted for stock splits, stock
dividends and the like) plus (ii) the documented, per share amount of any taxes
paid by the Officer with respect to such Non-Vested Shares on account of Section
83 of the Internal Revenue Code of 1986, as amended minus (iii) the amount of
any tax reduction realized by the Officer during the tax year in which the
repurchase occurs as a result of the application of the capital loss
attributable to the repurchase to offset other capital gains. The Company may
elect to exercise its Repurchase Option pursuant to the provision of Section 3.2
below. In the event that the Company does not elect to exercise its Repurchase
Option, all of the Non-Vested Shares shall thereafter be deemed to be Vested
Shares.

         3.2. Exercise of Repurchase Option and Closing. The Company may 
              -----------------------------------------
exercise the Repurchase Option by delivering or mailing to the Officer, in
accordance with Section 8.7, written notice of its election to exercise within
45 days after the Termination Event. If and to the extent the Repurchase Option
is not so exercised within such 45-day period, the Repurchase Option shall
automatically expire and terminate effective upon the expiration of such 45-day
period. The closing of any such repurchase of Non-Vested Shares shall be held at
the principal office of the Company, or at such other location as the parties to
such repurchase may mutually determine. At any such closing, the Company shall
pay to the Officer and/or any holder of the Non-Vested Shares the aggregate
repurchase price for the Non-Vested Shares to be purchased by certified or bank
check. At such time, the Officer and/or any holder of the Non-Vested Shares
shall deliver to the Company the certificate or certificates representing the
Non-Vested Shares so repurchased, duly endorsed for transfer, free and clear of
any liens or encumbrances.

         Section 4.  Restrictions on Transfer of Shares. None of the Shares now
                     ----------------------------------
owned or hereafter acquired shall be sold, assigned, transferred, pledged,
hypothecated, given away or in any other manner disposed of or encumbered,
whether voluntarily or by operation of law, unless such transfer is in
compliance with all foreign, federal and state securities laws (including,
without limitation, the Act), and such disposition is in accordance with the
terms and conditions of this 

                                       3
<PAGE>
 
Section 4. In connection with any transfer of Shares, the Company may require an
opinion of counsel to the transferor, reasonably satisfactory to the Company,
that such transfer is in compliance with all foreign, federal and state
securities laws (including without limitation, the Act). Any attempted
disposition of Shares not in accordance with the terms and conditions of this
Section 4 shall be null and void, and the Company shall not reflect on its
records any change in record ownership of any Shares as a result of any such
disposition, shall otherwise refuse to recognize any such disposition and shall
not in any way give effect to any such disposition of any Shares. The Officer is
also a party to a certain Stockholders' Agreement dated as of the date hereof by
and among the Company and its stockholders (the "Stockholders' Agreement").
Subject to the foregoing general provisions and except as otherwise amended by
this Section 4, Non-Vested Shares may be transferred to Permitted Transferees
(as defined in the Stockholders' Agreement) and Vested Shares may be transferred
in accordance with and subject to the provisions of the Stockholders' Agreement.

         Section 5.  Legend.  Any certificate (s) representing the Shares shall 
                     ------
carry the following legends:

                         "The transferability of this Certificate and the shares
                of stock represented hereby are subject to the restrictions,
                terms and conditions (including repurchase and restrictions
                against transfers) contained in a certain Stock Purchase and
                Restriction Agreement dated as of March 14, 1996 between the
                Company and Guy M. Lammle (copies of which are available at the
                offices of the Company for examination)."

                and

                         "The shares represented by this Stock Certificate have
                not been registered under the Securities Act of 1933 or the
                securities laws of any State. The shares may not be sold or
                transferred in the absence of such registration or an exemption
                from registration."

         Section 6.  Escrow. In order to more effectively carry out the 
                     ------
provisions of Sections 3 and 4 of this Agreement, the Company shall hold the
Shares in escrow together with a stock power endorsed by the Officer in blank.
The Company shall not dispose of the Shares except as otherwise provided in this
Agreement or the Stockholders' Agreement. If the Company exercises the
Repurchase Option, the Company is hereby authorized by the Officer to date and
complete the stock powers necessary for the transferto the Company of the Shares
it has duly elected to purchase and to transfer the Shares being purchased to
the Company. At such time as any Shares are transferred pursuant to Section 4
(including pursuant to the right of first refusal provisions in the
Stockholders' Agreement), the Company shall, at the written request of the
Officer, deliver to the Officer (or his proposed transferee) a certificate
representing such Shares with the balance of the Shares to be held in escrow
pursuant to this Section 6. All Shares which remain in escrow upon the
termination 

                                       4
<PAGE>
 
of this Agreement shall then be delivered to the Officer and/or the record
holders of such Shares. The right to vote the Shares and to receive cash
dividends on the Shares shall remain in the Officer unless and until the Shares
are purchased by the Company pursuant to the Repurchase Option.

         Section 7.  Withholding Taxes. The Officer acknowledges and agrees that
                     -----------------
the Company has the right to deduct from payments of any kind otherwise due to
the Officer, or from the Shares held pursuant to Section 6 hereof, any federal,
state or local taxes of any kind required by law to be withheld with respect to
the purchase of the Shares by the Officer. In furtherance of the foregoing the
Officer agrees that if he elects, in accordance with Section 83(b) of the
Internal Revenue Code of 1986, as amended, to recognize ordinary income in the
year of acquisition of the Shares, the Officer will pay to the Company all
withholding taxes shown as due on his Section 83(b) election form, or otherwise
ultimately determined to be due with respect to such election, based on the
difference, if any, between the purchase price for such Shares and the fair
market value of such Shares as of the date of the purchase of such Shares by the
Officer.

         Section 8.  Miscellaneous Provisions.
                     ------------------------

         8.1  Termination. The restrictions on transfers of Vested Shares
              -----------
contemplated by Section 4 hereof shall terminate as provided in the
Stockholders' Agreement; provided, however, that all other provisions of this
Agreement (including restrictions on transfers of Non-Vested Shares) shall
remain in effect until all of the Shares shall have become Vested Shares.

         8.2. Equitable Relief. The parties hereto agree and declare that legal
              ----------------
remedies may be inadequate to enforce the provisions of this Agreement and that
equitable relief, including specific performance and injunctive relief, may be
used to enforce the provisions of this Agreement.

         8.3. Change and Modifications.  This Agreement may not be orally 
              ------------------------
changed, modified or terminated, nor shall any oral waiver of any of its terms
be effective. This Agreement may be changed, modified or terminated only by an
agreement in writing signed by the Company and the Officer.

         8.4. Governing Law; Entire Agreement.  This Agreement shall be 
              -------------------------------
governed by and construed in accordance with the laws of the State of Delaware.
This Agreement, together with the Stockholders' Agreement and other agreements
specifically contemplated hereby and thereby, is intended by the parties as a
final expression of their agreement and intended to be complete and exclusive
statement of the agreement and understanding of the parties hereto in respect of
the subject matter contained herein and therein. This Agreement and the

         8.5. Headings.  The headings are intended only for convenience in 
              --------
finding the subject matter and do not constitute part of the text of this
Agreement and shall not be considered in the interpretation of this Agreement.

         8.6. Saving Clause.  If any provision(s) of this Agreement shall be

              -------
shall be in writing and be deemed given when delivered personally, by telex or
facsimile transmission or when received if mailed by first class registered or
certified mail, postage prepaid. Notices to the Company or the Officer shall be
addressed as set forth underneath their signatures below, or to such other
address or addresses as may have been furnished by such party in writing to the
other. Notices to any holder of the Shares other than the Officer shall be
addressed to the address furnished by such holder to the Company.

         8.8. Benefit and Binding Effect. This Agreement shall be binding upon
              --------------------------
and shall inure to the benefit of the parties hereto, their respective
successors, assigns, and legal representatives. The Company has the right to
assign this Agreement, and such assignee shall become entitled to all the rights
of the Company hereunder to the extent of such assignment. Notwithstanding
anything herein to the contrary, an assignment by the Company shall not relieve
the Company of the obligation to pay any part of the aggregate repurchase price
for Non-Vested Shares which is not paid by the Company's assignee.

                           INDEMNIFICATION AGREEMENT
                           -------------------------

         This Agreement made and entered into as of March 14, 1996
("Agreement"), by and between R&D Systems Company (the "Company," which term
shall include any Entity (as hereinafter defined), directly or indirectly,
controlled by or affiliated with the Company) and [each director]
("Indemnitee").

         WHEREAS, it is essential to the Company that it be able to retain and
attract as directors the most capable persons available;

         WHEREAS, increased corporate litigation has subjected directors to
litigation risks and expenses, and the limitations on the availability of
directors and officers liability insurance have made it increasingly difficult
for the Company to attract and retain such persons;

         WHEREAS, the Company's by-laws require the Company to indemnify its
directors and officers to the fullest extent permitted by law and permit it to
make other indemnification arrangements and agreements;

         WHEREAS, the Company desires to provide Indemnitee with specific
contractual assurance of Indemnitee's rights to full indemnification against
litigation risks and expenses (regardless, among other things, of any amendment
to or revocation of such by-laws or any change in the ownership of the Company
or the composition of its Boards of Directors), which indemnification is
intended to be greater than that which is afforded by the Company's charter,
by-laws and, to the extent insurance is available, the coverage of Indemnitee
under the Company's directors and officers liability insurance policies; and

         WHEREAS, Indemnitee is relying upon the rights afforded under this
Agreement in entering and continuing in Indemnitee's position as a director of
the Company:

         NOW, THEREFORE, in consideration of the premises and the covenants
contained herein, the Company and Indemnitee do hereby covenant and agree as
follows:

                     Company, (ii) in any capacity with respect to any
                     employee benefit plan of the Company or any

                     partner, trustee, officer, employee, agent or owner

                     criminal, administrative or investigative, whether formal
                     or informal, including a proceeding initiated by Indemnitee
                     pursuant to Section 10 of this Agreement to enforce
                     Indemnitee's rights hereunder.

              (g)    "Subsidiary" shall mean any Entity that is directly or
                     indirectly wholly-owned or controlled by the Company.

         2.   Services of Indemnitee. In consideration of the Company's
              ----------------------
covenants and commitments hereunder, Indemnitee agrees to serve or continue to
serve as a director of the Company. However, this Agreement shall not impose any
obligation on Indemnitee or the Company to continue Indemnitee's service to the
Company or any other Entity beyond any period otherwise required by law or by
other agreements or commitments of the parties, if any, and subject to the
foregoing, Indemnitee shall be free to resign from any position he holds at any
time.

         3.   Agreement to Indemnify. The Company agrees to indemnify Indemnitee
              ----------------------
as follows:

              (a)   Subject to the exceptions contained in Section 4(a) below,
                    if Indemnitee was or is a party or is threatened to be made
                    a party to any Proceeding (other than an action by or in the
                    right of the Company) by reason of Indemnitee's Corporate
                    Status, Indemnitee shall be indemnified by the Company
                    against all Expenses and Liabilities incurred or paid by

                                       2
<PAGE>
 
 
                    Indemnitee in connection with such Proceeding (referred to
                    herein as "Indemnifiable Expenses" and "Indemnifiable
                    Liabilities," respectively, and collectively as
                    "Indemnifiable Amounts").

              (b)   Subject to the exceptions contained in Section 4(b) below,
                    if Indemnitee was or is a party or is threatened to be made
                    a party to any Proceeding by or in the right of the Company
                    to procure a judgment in its favor by reason of Indemnitee's
                    Corporate Status, Indemnitee shall be indemnified by the
                    Company against all Indemnifiable Expenses.

         4.   Exceptions to Indemnification. Indemnitee shall be entitled to
              -----------------------------
indemnification under Sections 3(a) and 3(b) above in all circumstances other
than the following:

              (a)   If indemnification is requested under Section 3(a) and it
                    has been adjudicated finally by a court of competent
                    jurisdiction that, in connection with the subject of the
                    Proceeding out of which the claim for indemnification has
                    arisen, Indemnitee failed to act in good faith and in a
                    manner Indemnitee reasonably believed to be in or not
                    opposed to the best interests of the Company or the
                    relevant Entity, or, with respect to any criminal action or
                    proceeding, Indemnitee had reasonable cause to believe that
                    Indemnitee's conduct was unlawful, Indemnitee shall not be
                    entitled to payment of Indemnifiable Amounts hereunder.
                    
              (b)   If indemnification is requested under Section 3(b) and

                                  (i)     it has been adjudicated finally by a
                                          court of competent jurisdiction that,
                                          in connection with the subject of the
                                          Proceeding out of which the claim for
                                          indemnification has arisen, Indemnitee
                                          failed to act in good faith and in a
                                          manner Indemnitee reasonably believed
                                          to be in or not opposed to the best
                                          interests of the Company or the
                                          relevant Entity, Indemnitee shall not
                                          be entitled to payment of
                                          Indemnifiable Expenses hereunder; or

                                  (ii)    it has been adjudicated finally by a
                                          court of competent jurisdiction that
                                          Indemnitee is liable to the Company or
                                          the relevant Entity with respect to
                                          any claim, issue or matter involved in
                                          the Proceeding out of which the claim
                                          for indemnification has arisen,
                                          including, without limitation, a claim
                                          that Indemnitee received an improper
                                          personal benefit, no Indemnifiable
                                          Expenses shall be paid with respect to
                                          such claim, issue or matter unless the
                                          Court of Chancery or another court in
                                          which such Proceeding was brought
                                          shall determine upon application that,
                                          despite the adjudication of liability,
                                          but in view of all the 

                                       3
<PAGE>

 
                                          circumstances of the case, Indemnitee
                                          is fairly and reasonably entitled to
                                          indemnity for such Indemnifiable
                                          Expenses which such court shall deem
                                          proper.

         5.   Procedure for Payment of Indemnifiable Amounts. Indemnitee shall
              ----------------------------------------------
submit to the Company a written request specifying the Indemnifiable Amounts for
which Indemnitee seeks payment under Section 3 of this Agreement and the basis
for the claim. The Company shall pay such Indemnifiable Amounts to Indemnitee
within twenty (20) calendar days of receipt of the request. At the request of
the Company, Indemnitee shall furnish such documentation and information as are
reasonably available to Indemnitee and necessary to establish that Indemnitee is
entitled to indemnification hereunder.

         6.   Indemnification for Expenses of a Party Who is Wholly or Partly
              ---------------------------------------------------------------
Successful. Notwithstanding any other provision of this Agreement, and without
- ----------
limiting any such provision, to the extent that Indemnitee is, by reason of
Indemnitee's Corporate Status, a party to and is successful, on the merits or
otherwise, in any Proceeding, Indemnitee shall be indemnified against all
Expenses reasonably incurred by Indemnitee or on Indemnitee's behalf in
connection therewith. If Indemnitee is not wholly successful in such Proceeding
but is successful, on the merits or otherwise, as to one or more but less than
all claims, issues or matters in such Proceeding, the Company shall indemnify
Indemnitee against all Expenses reasonably incurred by Indemnitee or on
Indemnitee's behalf in connection with each successfully resolved claim, issue
or matter. For purposes of this Agreement, the termination of any claim, issue
or matter in such a Proceeding by dismissal, with or without prejudice, shall be
deemed to be a successful result as to such claim, issue or matter.

         7.   Effect of Certain Resolutions. Neither the settlement or
              -----------------------------
termination of any Proceeding nor the failure of the Company to award
indemnification or to determine that indemnification is payable shall create an
adverse presumption that Indemnitee is not entitled to indemnification
hereunder. In addition, the termination of any proceeding by judgment, order,
settlement, conviction, or upon a plea of nolo contendere or its equivalent
shall not create a presumption that Indemnitee did not act in good faith and in
a manner which Indemnitee reasonably believed to be in or not opposed to the
best interests of the Company or, with respect to any criminal action or
proceeding, had reasonable cause to believe that Indemnitee's action was
unlawful.

         8.   Agreement to Advance Interim Expenses; Conditions. The Company
              -------------------------------------------------
shall advance to Indemnitee all Indemnifiable Expenses incurred by Indemnitee in
connection with any Proceeding, including a Proceeding by or in the right of the
Company, in advance of the final disposition of such Proceeding, if Indemnitee
furnishes the Company with a written undertaking to repay the amount of such
Indemnifiable Expenses advanced to Indemnitee if it is finally determined by a
court of competent jurisdiction that Indemnitee is not entitled under this
Agreement to indemnification with respect to such Expenses. Such undertaking
shall be an unlimited general obligation of Indemnitee, shall be accepted by the
Company without regard to the financial ability of Indemnitee to make repayment,
and in no event shall be required to be secured.

                                       4
<PAGE>
 
 
         9.   Procedure for Payment of Interim Expenses. Indemnitee shall submit
              -----------------------------------------
to the Company a written request specifying the Indemnifiable Expenses for which
Indemnitee seeks an advancement under Section 8 of this Agreement, together with
documentation evidencing that Indemnitee has incurred such Indemnifiable
Expenses. Payment of Indemnifiable Expenses under Section 8 shall be made no
later than twenty (20) calendar days after the Company's receipt of such request
and the undertaking required by Section 8.

         10.  Remedies of Indemnitee.
              ----------------------

              (a)      Right to Petition Court. In the event that Indemnitee
                       -----------------------
                       makes a request for payment of Indemnifiable Amounts
                       under Sections 3 and 5 above or a request for an
                       advancement of Indemnifiable Expenses under Sections 8
                       and 9 above and the Company fails to make such payment or
                       advancement in a timely manner pursuant to the terms of
                       this Agreement, Indemnitee may petition the Court of
                       Chancery or other appropriate court with jurisdiction
                       over this matter to enforce the Company's obligations
                       under this Agreement.

              (b)      Burden of Proof. In any judicial proceeding brought under
                       ---------------
                       Section 10(a) above, the Company shall have the burden of
                       proving that Indemnitee is not entitled to payment of
                       Indemnifiable Amounts hereunder.

              (c)      Expenses. The Company agrees to reimburse Indemnitee in
                       --------
                       full for any Expenses incurred by Indemnitee in
                       connection with investigating, preparing for, litigating,
                       defending or settling any action brought by Indemnitee
                       under Section 10(a) above, or in connection with any
                       claim or counterclaim brought by the Company in
                       connection therewith, but only if and to the extent
                       Indemnitee prevails therein. If it shall be determined in
                       such action that Indemnitee is entitled to receive part
                       but not all of the advancement or indemnification sought,
                       the expenses incurred by Indemnitee in connection with
                       such action shall be appropriately prorated.

              (d)      Validity of Agreement. The Company shall be precluded
                       ---------------------
                       from asserting in any Proceeding, including, without
                       limitation, an action under Section 10(a) above, that the
                       provisions of this Agreement are not valid, binding and
                       enforceable, that there is insufficient consideration for
                       this Agreement or that this Agreement and the actions of
                       the Company's Board of Directors in approving this
                       Agreement constituted a breach of their fiduciary
                       obligations and shall stipulate in court that the Company
                       is bound by all the provisions of this Agreement.

              (e)      Failure to Act Not a Defense. The failure of the Company
                       ----------------------------
                       (including its Board of Directors or any committee
                       thereof, independent legal counsel, or shareholders) to
                       make a determination concerning the permissibility of the
                       payment of Indemnifiable Amounts or the advancement of
                       Indemnifiable 

                                       5
<PAGE>
 
 
                       Expenses under this Agreement shall not be a defense in
                       any action brought under Section 10(a) above, and shall
                       not create a presumption that such payment or advancement
                       is not permissible.

         11.  Representations and Warranties of the Company. The Company hereby
              ---------------------------------------------
represents and warrants to Indemnitee as follows:

              (a)      Authority. The Company has all necessary power and
                       ---------
                       authority to enter into, and be bound by the terms of,
                       this Agreement, and the execution, delivery and
                       performance of the undertakings contemplated by this
                       Agreement have been duly authorized by the Company.

              (b)      Enforceability. This Agreement, when executed and
                       --------------
                       delivered by the Company in accordance with the
                       provisions hereof, shall be a legal, valid and binding
                       obligation of the Company, enforceable against the
                       Company in accordance with its terms, except as such
                       enforceability may be limited by applicable bankruptcy,
                       insolvency, moratorium, reorganization or similar laws
                       affecting the enforcement of creditors' rights generally.

         12.  Insurance. The Company will use its commercially reasonable
              --------- 
efforts to obtain and maintain a policy or policies of insurance with a
reputable insurance company or companies providing the Indemnitee with coverage
for losses from wrongful acts, and to ensure the Company's performance of its
indemnification obligations under this Agreement. In all policies of director
and officer liability insurance, Indemnitee shall be named as an insured in such
a manner as to provide Indemnitee at least the same rights and benefits as are
accorded to the most favorably insured of the Company's officers and directors.
Notwithstanding the foregoing, if the Company, after employing commercially
reasonable efforts as provided in the immediately preceding sentence, determines
in good faith that such insurance is not available, if the premium costs for
such insurance are disproportionate to the amount of coverage provided, or if
the coverage provided by such insurance is limited by exclusions so as to
provide an insufficient benefit, the Company shall use its commercially
reasonable efforts to obtain and maintain a policy or policies of insurance with
coverage having features as similar as practicable to those described above.

         13.  Contract Rights Not Exclusive. The rights to payment of
              -----------------------------
Indemnifiable Amounts and advancement of Indemnifiable Expenses provided by this
Agreement shall be in addition to, but not exclusive of, any other rights which
Indemnitee may have at any time under applicable law, the Company's by-laws or
charter, or any other agreement, vote of shareholders or directors, or
otherwise, both as to action in Indemnitee's official capacity and as to action
in any other capacity as a result of Indemnitee's serving as a director of the
Company.

         14.  Successors. This Agreement shall be (a) binding upon all
              ----------
successors and assigns of the Company (including any transferee of all or a
substantial portion of the business, stock and/or assets of the Company and any
direct or indirect successor by merger or consolidation or otherwise by
operation of law) and (b) binding on and shall inure to the benefit of the
heirs, 

                                       6
<PAGE>
 

personal representatives, executors and administrators of Indemnitee. This
Agreement shall continue for the benefit of Indemnitee and such heirs, personal
representatives, executors and administrators after Indemnitee has ceased to
have Corporate Status.

         15.  Subrogation. In the event of any payment of Indemnifiable Amounts
              -----------
under this Agreement, the Company shall be subrogated to the extent of such
payment to all of the rights of contribution or recovery of Indemnitee against
other persons, and Indemnitee shall take, at the request of the Company, all
reasonable action necessary to secure such rights, including the execution of
such documents as are necessary to enable the Company to bring suit to enforce
such rights.

         16.  Change in Law. To the extent that a change in applicable law
              -------------
(whether by statute or judicial decision) shall permit broader indemnification
than is provided under the terms of the by-laws of the Company and this
Agreement, Indemnitee shall be entitled to such broader indemnification and this
Agreement shall be deemed to be amended to such extent.

         17.  Severability. Whenever possible, each provision of this Agreement
              ------------
shall be interpreted in such a manner as to be effective and valid under
applicable law, but if any provision of this Agreement, or any clause thereof,
shall be determined by a court of competent jurisdiction to be illegal, invalid
or unenforceable, in whole or in part, such provision or clause shall be limited
or modified in its application to the minimum extent necessary to make such
provision or clause valid, legal and enforceable, and the remaining provisions
and clauses of this Agreement shall remain fully enforceable and binding on the
parties.

         18.  Indemnitee as Plaintiff. Except as provided in Section 10(c) of
              -----------------------
this Agreement and in the next sentence or in connection with any
indemnification claim under any acquisition or investment agreement of even
date, Indemnitee shall not be entitled to payment of Indemnifiable Amounts or
advancement of Indemnifiable Expenses with respect to any Proceeding brought by
Indemnitee against the Company, any Subsidiary or any Entity which the Company
directly or indirectly controls or is affiliated with, any director or officer
thereof, or any third party, unless the Company has consented to the initiation
of such Proceeding. This Section shall not apply to counterclaims or affirmative
defenses asserted by Indemnitee in an action brought against Indemnitee.

         19.  Modifications and Waiver. Except as provided in Section 16 above
              ------------------------
with respect to changes in applicable law which broaden the right of Indemnitee
to be indemnified by the Company, no supplement, modification or amendment of
this Agreement shall be binding unless executed in writing by each of the
parties hereto. No waiver of any of the provisions of this Agreement shall be
deemed or shall constitute a waiver of any other provisions of this Agreement
(whether or not similar), nor shall such waiver constitute a continuing waiver.

         20.  General Notices. All notices, requests, demands and other
              ---------------
communications hereunder shall be in writing and shall be deemed to have been
duly given (a) when delivered by hand, (b) when transmitted by facsimile and

                           NON-COMPETITION AGREEMENT
                           -------------------------

         This Agreement is made and entered into as of March 14, 1996 by and
between R&D Systems Company, a Delaware corporation (the "Company"), and Guy M.
Lammle ("Founder").

         WHEREAS, certain investors have agreed to provide financing (the
"Financing") to the Company subject to the terms of that certain Stock Purchase
Agreement (the "Stock Purchase Agreement"), dated as of the date hereof, by and
among the Company, the Founder, the other stockholders of the Company identified
therein, and the investors identified therein;

         WHEREAS, a portion of the proceeds from the Financing will be used by
the Company to repurchase outstanding capital stock held by the Founder;

         WHEREAS, the Founder is an executive of the Company; and

         WHEREAS, the execution of this Agreement by the Company and the Founder
is a condition precedent to the transactions contemplated by the Stock Purchase
Agreement.

         NOW, THEREFORE, in consideration of the mutual covenants contained
herein and other good and valuable consideration, the receipt and sufficiency of
which is hereby acknowledged, the Company and the Founder agree as follows:

         1.    Confidential Information, Non-Competition and Non-Solicitation.
               --------------------------------------------------------------

               (a)   Definitions.
                     -----------

                     (i)   Proprietary Information.  As used in this Agreement,
                           -----------------------
               "Proprietary Information" means information which the Company
               possesses or to which the Company has rights which has commercial
               value. Proprietary Information includes, by way of example and
               without limitation, trade secrets, product ideas, designs,
               configurations, processes, techniques, formulas, software,
               improvements, inventions, data, know-how, copyrightable
               materials, marketing plans and strategies, sales and financial
               reports and forecasts, and customer lists. Proprietary
               Information includes information developed by the Founder in the
               course of the Founder's employment by the Company or otherwise
               relating to Inventions which belong to the Company under Section
               1(d) below, as well as other information to which the Founder may
               have access in connection with the Founder's employment.

                     (ii)  Inventions and Developments.  As used in this
                           ---------------------------
               Agreement, "Inventions and Developments" means any and all
               inventions, developments, creative works and useful ideas of any
               description whatsoever, whether or not 
<PAGE>
 
               patentable or copyrightable. Inventions and Developments include,
               by way of example and without limitation, discoveries or
               improvements which consist of or relate to any form of
               Proprietary Information.

                     (iii) Company-Related Inventions and Developments.
                           -------------------------------------------
               For purposes of this Agreement, "Company-Related Inventions and
               Developments" means all Inventions and Developments which either
               (A) relate at the time of conception or development to the actual
               or demonstrably anticipated business of the Company or to its
               actual or demonstrably anticipated research and development; (B)
               result from or relate to any work performed for the Company,
               whether or not during normal business hours; (C) are developed on
               Company time; or (D) are developed through the use of the
               Company's Proprietary Information, equipment and software, or
               other facilities or resources.

               (b) Confidentiality. The Founder understands and agrees that
                   ---------------
         the Founder's employment has created a relationship of confidence and
         trust between the Founder and the Company with respect to (i) all
         Proprietary Information, (ii) the confidential information of others
         with which the Company has a business relationship with reasonable
         expectations (whether as a result of a contract or otherwise) that such
         information will not be disclosed and (iii) any information about the
         financing and transactions related to the financing, including but not
         limited to amounts paid, parties involved, ownership interests sold and
         restrictions on the Company and its stockholders. The information
         referred to in clauses (i), (ii) and (iii) of the preceding sentence is
         referred to in this Agreement, collectively, as "Confidential
         Information." At all times, both during the Founder's employment with
         the Company and after its termination, the Founder will keep in
         confidence and trust all such Confidential Information, and will not
         use or disclose any such Confidential Information without the written
         consent of the Company, except as may be necessary in the ordinary
         course of performing the Founder's duties to the Company except to the
         extent required by applicable law or court order (in each case
         following notice to the Company) and except for disclosure to the
         Founder's attorneys and assessments for tax, estate planning on legal
         purposes. The restrictions set forth in this Section 1(b) will not
         apply to information which is or becomes known to the public or in the
         trade, unless such knowledge results from an unauthorized disclosure by
         the Founder, but this exception will not affect the application of any
         other provision of this Agreement to such information in accordance
         with the terms of such provision.

               (c) Documents, Records, etc. All documents, records, apparatus,
                   -----------------------
         equipment and other physical property, whether or not pertaining to
         Confidential Information, furnished to the Founder by the Company or
         produced by the Founder in connection with the Founder's employment
         will be and remain the sole property of the Company. The Founder will
         return to the Company all such materials and property as and when
         requested by the Company. In any event, the Founder will return all
         such materials and property immediately upon termination of the
         Founder's employment for any reason. The

                                       2
<PAGE>
 
         Founder will not retain with the Founder any such material or property
         or any copies thereof after such termination, except that one copy of
         any such materials may be delivered to independent counsel for the
         Company to the extent the Founder deems it reasonably necessary to
         preserve any of its rights hereunder, provided that such independent
         counsel is reasonably acceptable to the Company, and the Founder
         provides prior notice to the Company describing any such materials and
         such independent counsel agrees to keep such material confidential.

               (d) Ownership of Inventions and Developments. The Founder agrees
                   ----------------------------------------
         that all Company-Related Inventions and Developments which the Founder
         conceives, creates or develops, in whole or in part, either alone or
         jointly with others, prior to or during the course of the Founder's
         employment with the Company will be the sole property of the Company.
         The Founder agrees that the Company will be the sole owner of all
         patents, copyrights and other proprietary rights in and with respect to
         such Company-Related Inventions and Developments. To the fullest extent
         permitted by law, such Company-Related Inventions and Developments will
         be deemed works made for hire. The Founder hereby transfers and assigns
         to the Company any proprietary rights which the Founder may have or
         acquire in any such Company-Related Inventions and Developments. The
         Founder agrees to execute any documents and take any actions that may
         be required to effect and confirm such transfer and assignment and
         waiver. The provisions of this Section 1(d) will apply to all Company-
         Related Inventions and Developments which are conceived, created or
         developed during the course of the Founder's employment with the
         Company, whether before or after the date of this Agreement, and
         whether or not further development or reduction to practice may take
         place after termination of the Founder's employment, for which purpose
         it will be presumed that any Company-Related Inventions and
         Developments conceived by the Founder which are reduced to practice
         within one year after termination of the Founder's employment were
         conceived during the course of the Founder's employment with the
         Company unless the Founder is able to establish a later conception date
         by clear and convincing evidence. The provisions of this Section 1(d)
         will not apply, however, to any Inventions and Developments which may
         be disclosed in a separate Schedule attached to this Agreement prior to
         its acceptance by the Company, representing Inventions and Developments
         made by the Founder prior to the Founder's employment by the Company.

               (e) Disclosure of Inventions and Developments. The Founder
                   -----------------------------------------
         agrees promptly to disclose to the Company, or any persons designated
         by it, all Company-Related Inventions and Developments which are or may
         be subject to the provisions of Section 1(d).

               (f) Obtaining and Enforcing Proprietary Rights. The Founder
                   ------------------------------------------
         agrees to assist the Company, at the Company's request from time to
         time and at the Company's expense, to obtain and enforce patents,
         copyrights or other proprietary rights with respect to Company-Related
         Inventions and Developments in any and all countries. The Founder 

                                       3
<PAGE>
 
         will execute all documents reasonably necessary or appropriate for this
         purpose. This obligation will survive the termination of the Founder's
         employment, provided that the Company will compensate the Founder at a
         reasonable rate after such termination for time actually spent by the
         Founder at the Company's request on such assistance. In the event that
         the Company is unable for any reason whatsoever to secure the Founder's
         signature to any document reasonably necessary or appropriate for any
         of the foregoing purposes (including renewals, extensions,
         continuations, divisions or continuations in part), the Founder hereby
         irrevocably designates and appoints the Company and its duly authorized
         officers and agents as the Founder's agents and attorneys-in-fact to
         act for the Founder and on the Founder's behalf, but only for the
         purpose of executing and filing any such document and doing all other
         lawfully permitted acts to accomplish the foregoing purposes with the
         same legal force and effect as if executed by the Founder.

               (g) Third-Party Agreements and Rights. The Founder hereby
                   ---------------------------------
         confirms that the Founder is not bound by the terms of any agreement
         with any previous company or other party which restricts in any way the
         Founder's use or disclosure of information or the Founder's engagement
         in any business. The Founder represents to the Company that the
         Founder's execution of this Agreement, the Founder's employment with
         the Company and the performance of the Founder's proposed duties for
         the Company will not violate any obligations the Founder may have to
         any such previous company or other party. In the Founder's work for the
         Company, the Founder will not disclose or make use of any information
         in violation of any agreements with or rights of any such previous
         company or other party, and the Founder will not bring to the premises
         of the Company any copies or other tangible embodiments of non-public
         information belonging to or obtained from any such previous employment
         or other party.

               (h) Non-competition and Non-solicitation. For a period
                   ------------------------------------
         beginning on the date hereof and ending on the later of the fourth
         anniversary of the date hereof and the second anniversary of the date
         on which the Founder ceases to be employed by the Company for any
         reason whatsoever, the Founder, directly or indirectly, whether as
         owner, sole proprietor, partner, shareholder, director, consultant,
         agent, Founder, co-venturer or otherwise, (i) will not engage,
         participate or invest in any business activity anywhere in the world
         which develops, manufactures or markets products or performs services
         which are competitive with the products or services of the Company at
         the time of the Founder's termination, or products or services which
         the Company has under development at the time of the Founder's
         termination or which are the subject of active planning at any time
         during the course of the Founder's employment (and which active
         planning is not thereafter abandoned); provided, however, that the
                                                --------  -------
         Founder may own, as a passive investor, publicly-traded securities of
         any corporation which competes with the business of the Company so long
         as such securities do not, in the aggregate, constitute more than 1% of
         any class of outstanding securities of such corporation, (ii) will
         refrain from hiring or attempting to employ, recruiting or otherwise
         soliciting, inducing or influencing any person to leave employment with
         the Company or its resellers or distributors, and (iii)

                                       4
<PAGE>
 
         will refrain from directly or indirectly soliciting business from any
         of the Company's customers, end users, resellers or distributors on
         behalf of any business which competes with the Company. The Founder
         understands that the restrictions set forth in this Section 1(h) are
         intended to protect the Company's interest in its Proprietary
         Information and established customer relationships and goodwill, and
         agrees that such restrictions are reasonable and appropriate for this
         purpose.

               (i) Injunction. The Founder agrees that it would be difficult
                   ----------
         to measure any damages caused to the Company which might result from
         any breach by the Founder of the promises set forth in this Agreement,
         and that in any event money damages would be an inadequate remedy for
         any such breach. Accordingly, the Founder agrees that if the Founder
         breaches, or proposes to breach, any portion of this Agreement, the
         Company shall be entitled, in addition to all other remedies that it
         may have, to an injunction or other appropriate equitable relief to
         restrain any such breach without showing or proving any actual damage
         to the Company.

         2.    Extent of Service. So long as the Founder is employed by the
               -----------------
Company, the Founder shall devote all of the Founder's business time, attention
and energies, best efforts and business judgment, skill and knowledge to the
advancement of the Company's interests and to the discharge of the Founder's
duties and responsibilities hereunder. The Founder shall not engage in any other
business activity, except as may be approved by two-thirds of the Board of
Directors; provided, however, that nothing herein shall be construed as
preventing the Founder from the following:

               (a) investing the Founder's assets in any other entity in a
         manner not prohibited by Section 1(h) hereof and in such form or manner
         as shall not require any material services on the Founder's part in the
         operations or affairs of the companies or other entities in which such
         investments are made; or

               (b) acting as director of other companies so long as in a manner
         not prohibited by Section 1(h); or

               (c) engaging in religious, charitable or other community or
         non-profit activities that do not impair the Founder's ability to
         fulfill the Founder's duties and responsibilities consistent with the
         foregoing.

         3.    No Employment Obligation.  The Founder understands and agrees
               ------------------------
that this Agreement does not create an obligation on the part of the Company to
continue the Founder's employment by the Company. The Founder acknowledges and
agrees that, except as expressly provided in any subsequent agreement to the
contrary, he is an employee "at will."

         4.    Inclusion of Company's Subsidiaries. For the purposes of Sections
               -----------------------------------
1, 2, 3 and 5 hereof, all references to "Company" shall be deemed to include the
Company and each of its subsidiaries, as in existence from time to time.

         5.    Integration.  This Agreement and the Stock Purchase Agreement
               -----------
constitute the entire agreements between the parties with respect to the subject
matter hereof and supersede all prior agreements between the parties with
respect to any related subject matter.

         6.    Assignment; Successors and Assigns, etc. Neither the Company nor
               ---------------------------------------
the Founder may make any assignment of this Agreement or any interest herein, by
operation of law or otherwise, without the prior written consent of the other
party; provided, however, that the Company may assign its rights under this
Agreement without the consent of the Founder in the event that the Company shall
hereafter effect a reorganization, consolidate with or merge into any other
corporation, partnership, organization or other entity, or transfer all or
substantially all of its properties or assets to any other corporation,
partnership, organization or other entity in which even for purposes of Section
1(h) hereof as used in determining the scope of the Company's business,
references to the Company shall be deemed to refer to the Company immediately
prior to such reorganization, consolidation or merger. This Agreement shall
inure to the benefit of and be binding upon the Company and the Founder, their
respective successors, executors, administrators, heirs and permitted assigns.

         7.    Enforceability. If any portion or provision of this Agreement
               --------------
shall to any extent be declared illegal or unenforceable by a court of competent
jurisdiction, then the remainder of this Agreement, or the application of such
portion or provision in circumstances other than those as to which it is so
declared illegal or unenforceable, shall not be affected thereby, and each
portion and provision of this Agreement shall be valid and enforceable to the
fullest extent permitted by law.

         8.    Waiver. No waiver of any provision hereof shall be effective
               ------
unless made in writing and signed by the waiving party. The failure of any party
to require the performance of any term or obligation of this Agreement, or the
waiver by any party of any breach of this Agreement, shall not prevent any
subsequent enforcement of such term or obligation or be deemed a waiver of any
subsequent breach.

         9.    Notices.  Any notices, requests, demands and other communications
               -------
provided for by this Agreement shall be sufficient if in writing and delivered
in person or sent by registered or certified mail, postage prepaid, return
receipt requested, to the Founder at the last address the Founder has filed in
writing with the Company or, in the case of the Company, at its main offices,
attention of the Chairman of the Board of Directors.

         10.   Amendment.  This Agreement may be amended or modified only by a
               ---------
written instrument signed by the Founder and by a duly authorized representative
of the Company.

         11.   Governing Law.  This is a Colorado contract and shall be
               -------------
construed under and be governed in all respects by the internal laws of the
State of Colorado, without giving effect to its conflicts of law principles.

         12.   Counterparts.  This Agreement may be executed in any number of
               ------------
counterparts, each of which when so executed and delivered shall be taken to be
an original; but such counterparts shall together constitute one and the same
document.

         13.   Payment. In consideration of the covenants set forth in this
               -------
Agreement and provided that the Founder is not in material breach of this
Agreement, the Company agrees to pay to the Founder, by certified or bank
cashier's check or by wire transfer, the sum of $1,500,000 on the date hereof,
$500,000 on the first anniversary of the date hereof and $500,000 on the second
anniversary of the date hereof. The Founder acknowledges that such payments
shall be deemed as payment in full by the Company for the performance of such
covenants by the Founder.

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

              (a)      Definitions.
                       -----------

                       (i) Proprietary Information. As used in this
                           -----------------------
              Agreement, "Proprietary Information" means information which
              the Company possesses or to which the Company has rights which
              has commercial value. Proprietary Information includes, by way
              of example and without limitation, trade secrets, product
              ideas, designs, configurations, processes, techniques,
              formulas, software, improvements, inventions, data, know-how,

              information to which the Founder may have access in connection
              with the Founder's employment.

                       (ii) Inventions and Developments. As used in this
                            ---------------------------
              Agreement, "Inventions and Developments" means any and all
              inventions, developments, creative works and useful ideas of any
              description whatsoever, whether or not
<PAGE>
 
               patentable or copyrightable. Inventions and Developments include,
               by way of example and without limitation, discoveries or
               improvements which consist of or relate to any form of
               Proprietary Information.

                        (iii) Company-Related Inventions and Developments.
                              -------------------------------------------
               For purposes of this Agreement, "Company-Related Inventions
               and Developments" means all Inventions and Developments which
               either (A) relate at the time of conception or development to
               the actual or demonstrably anticipated business of the Company
               or to its actual or demonstrably anticipated research and
               development; (B) result from or relate to any work performed
               for the Company, whether or not during normal business hours;
               (C) are developed on Company time; or (D) are developed
               through the use of the Company's Proprietary Information,
               equipment and software, or other facilities or resources.

               (b) Confidentiality. The Founder understands and agrees that
                   ---------------
         the Founder's employment has created a relationship of confidence and
         trust between the Founder and the Company with respect to (i) all
         Proprietary Information (ii) the confidential information of others
         with which the Company has a business relationship with reasonable
         expectations (whether as a result of a contract or otherwise) that such
         information will not be disclosed and (iii) any information about the
         financing and transactions related to the financing, including but not
         limited to amounts paid, parties involved, ownership interests sold and
         restrictions on the Company and its stockholders. The information
         referred to in clauses (i), (ii) and (iii) of the preceding sentence is
         referred to in this Agreement, collectively, as "Confidential
         Information." At all times, both during the Founder's employment with
         the Company and after its termination, the Founder will keep in
         confidence and trust all such Confidential Information, and will not
         use or disclose any such Confidential Information without the written
         consent of the Company, except as may be necessary in the ordinary
         course of performing the Founder's duties to the Company except to the
         extent required by applicable law or court order (in each case
         following notice to the Company) and except for disclosure to the
         Founder's attorneys and assessments for tax, estate planning on legal
         purposes. The restrictions set forth in this Section 1(b) will not
         apply to information which is or becomes known to the public or in the
         trade, unless such knowledge results from an unauthorized disclosure by
         the Founder, but this exception will not affect the application of any
         other provision of this Agreement to such information in accordance
         with the terms of such provision.

               (c) Documents, Records, etc. All documents, records,
                   -----------------------
         apparatus, equipment and other physical property, whether or not
         pertaining to Confidential Information, furnished to the Founder by the
         Company or produced by the Founder in connection with the Founder's
         employment will be and remain the sole property of the Company. The
         Founder will return to the Company all such materials and property as
         and when requested by the Company. In any event, the Founder will
         return all such materials and property immediately upon termination of
         the Founder's employment for any reason. The 

                                       2
<PAGE>
 
         Founder will not retain with the Founder any such material or property
         or any copies thereof after such termination, except that one copy of
         any such materials may be delivered to independent counsel for the
         Company to the extent the Founder deems it reasonably necessary to
         preserve any of its rights hereunder, provided that such independent
         counsel is reasonably acceptable to the Company, and the Founder
         provides prior notice to the Company describing any such materials and
         such independent counsel agrees to keep such material confidential.

                  (d) Ownership of Inventions and Developments. The Founder
                      ----------------------------------------
         agrees that all Company-Related Inventions and Developments which the
         Founder conceives, creates or develops, in whole or in part, either
         alone or jointly with others, prior to or during the course of the
         Founder's employment with the Company will be the sole property of the
         Company. The Founder agrees that the Company will be the sole owner of
         all patents, copyrights and other proprietary rights in and with
         respect to such Company-Related Inventions and Developments. To the
         fullest extent permitted by law, such Company-Related Inventions and
         Developments will be deemed works made for hire. The Founder hereby
         transfers and assigns to the Company any proprietary rights which the
         Founder may have or acquire in any such Company-Related Inventions and
         Developments. The Founder agrees to execute any documents and take any
         actions that may be required to effect and confirm such transfer and
         assignment and waiver. The provisions of this Section 1(d) will apply
         to all Company-Related Inventions and Developments which are conceived,
         created or developed during the course of the Founder's employment with
         the Company, whether before or after the date of this Agreement, and
         whether or not further development or reduction to practice may take
         place after termination of the Founder's employment, for which purpose
         it will be presumed that any Company-Related Inventions and
         Developments conceived by the Founder which are reduced to practice
         within one year after termination of the Founder's employment were
         conceived during the course of the Founder's employment with the
         Company unless the Founder is able to establish a later conception date
         by clear and convincing evidence. The provisions of this Section 1(d)
         will not apply, however, to any Inventions and Developments which may
         be disclosed in a separate Schedule attached to this Agreement prior to
         its acceptance by the Company, representing Inventions and Developments
         made by the Founder prior to the Founder's employment by the Company.

                  (e) Disclosure of Inventions and Developments. The Founder
                      -----------------------------------------
         agrees promptly to disclose to the Company, or any persons designated
         by it, all Company-Related Inventions and Developments which are or may
         be subject to the provisions of Section 1(d).

                  (f) Obtaining and Enforcing Proprietary Rights. The Founder
                      ------------------------------------------
         agrees to assist the Company, at the Company's request from time to
         time and at the Company's expense, to obtain and enforce patents,
         copyrights or other proprietary rights with respect to Company-Related
         Inventions and Developments in any and all countries. The Founder

         will execute all documents reasonably necessary or appropriate for this
         purpose. This obligation will survive the termination of the Founder's
         employment, provided that the Company will compensate the Founder at a
         reasonable rate after such termination for time actually spent by the
         Founder at the Company's request on such assistance. In the event that
         the Company is unable for any reason whatsoever to secure the Founder's
         signature to any document reasonably necessary or appropriate for any
         of the foregoing purposes (including renewals, extensions,
         continuations, divisions or continuations in part), the Founder hereby
         irrevocably designates and appoints the Company and its duly authorized
         officers and agents as the Founder's agents and attorneys-in-fact to
         act for the Founder and on the Founder's behalf, but only for the
         purpose of executing and filing any such document and doing all other
         lawfully permitted acts to accomplish the foregoing purposes with the
         same legal force and effect as if executed by the Founder.

                  (g) Third-Party Agreements and Rights. The Founder hereby
                      ---------------------------------
         confirms that the Founder is not bound by the terms of any agreement
         with any previous company or other party which restricts in any way the
         Founder's use or disclosure of information or the Founder's engagement
         in any business. The Founder represents to the Company that the
         Founder's execution of this Agreement, the Founder's employment with
         the Company and the performance of the Founder's proposed duties for
         the Company will not violate any obligations the Founder may have to
         any such previous company or other party. In the Founder's work for the
         Company, the Founder will not disclose or make use of any information
         in violation of any agreements with or rights of any such previous
         company or other party, and the Founder will not bring to the premises
         of the Company any copies or other tangible embodiments of non-public
         information belonging to or obtained from any such previous employment
         or other party.

                  (h) Non-competition and Non-solicitation. For a period
                      ------------------------------------
         beginning on the date hereof and ending on the fourth anniversary of
         the date hereof, the Founder, directly or indirectly, whether as owner,
         sole proprietor, partner, shareholder, director, consultant, agent,
         Founder, co-venturer or otherwise, (i) will not engage, participate or
         invest in any business activity anywhere in the world which develops,
         manufactures or markets products or performs services which are
         competitive with the products or services of the Company at the time of
         the Founder's termination, or products or services which the Company
         has under development at the time of the Founder's termination or which
         are the subject of active planning at any time during the course of the
         Founder's employment (and which active planning is not thereafter
         abandoned); provided, however, that the Founder may own, as a passive
                     --------  -------
         investor, publicly-traded securities of any corporation which competes
         with the business of the Company so long as such securities do not, in
         the aggregate, constitute more than 1% of any class of outstanding
         securities of such corporation, (ii) will refrain from hiring or
         attempting to employ, recruiting or otherwise soliciting, inducing or
         influencing any person to leave employment with the Company or its
         resellers or distributors, and (iii) will refrain from directly or
         indirectly soliciting business from any of the Company's customers, end
         users, resellers or distributors on

                                       4
<PAGE>
 
         behalf of any business which competes with the Company. The Founder
         understands that the restrictions set forth in this Section 1(h) are
         intended to protect the Company's interest in its Proprietary
         Information and established customer relationships and goodwill, and
         agrees that such restrictions are reasonable and appropriate for this
         purpose.

                  (i) Injunction. The Founder agrees that it would be difficult
                      ----------
         to measure any damages caused to the Company which might result from
         any breach by the Founder of the promises set forth in this Agreement,
         and that in any event money damages would be an inadequate remedy for
         any such breach. Accordingly, the Founder agrees that if the Founder
         breaches, or proposes to breach, any portion of this Agreement, the
         Company shall be entitled, in addition to all other remedies that it
         may have, to an injunction or other appropriate equitable relief to
         restrain any such breach without showing or proving any actual damage
         to the Company.

         2. Extent of Service. So long as the Founder is employed by the
            -----------------
Company, the Founder shall devote all of the Founder's business time, attention
and energies, best efforts and business judgment, skill and knowledge to the
advancement of the Company's interests and to the discharge of the Founder's
duties and responsibilities hereunder. The Founder shall not engage in any other
business activity, except as may be approved by two-thirds of the Board of
Directors; provided, however, that nothing herein shall be construed as
preventing the Founder from the following:

                  (a) investing the Founder's assets in any other entity in a
         manner not prohibited by Section 1(h) hereof and in such form or manner
         as shall not require any material services on the Founder's part in the
         operations or affairs of the companies or other entities in which such
         investments are made; or

                  (b) acting as director of other companies so long as in a
         manner not prohibited by Section 1(h); or

                  (c) engaging in religious, charitable or other community or
         non-profit activities that do not impair the Founder's ability to
         fulfill the Founder's duties and responsibilities consistent with the
         foregoing.

         3. No Employment Obligation.  The Founder understands and agrees that
            ------------------------
this Agreement does not create an obligation on the part of the Company to
continue the Founder's employment by the Company. The Founder acknowledges and
agrees that, except as expressly provided in any subsequent agreement to the
contrary, he is an employee "at will."

         4. Inclusion of Company's Subsidiaries. For the purposes of Sections 1,
            -----------------------------------
2, 3 and 5 hereof, all references to "Company" shall be deemed to include the
Company and each of its subsidiaries, as in existence from time to time.

                                       5
<PAGE>
 
         5. Integration.  This Agreement and the Stock Purchase Agreement
            -----------
constitute the entire agreements between the parties with respect to the subject
matter hereof and supersede all prior agreements between the parties with
respect to any related subject matter.

         6. Assignment; Successors and Assigns, etc. Neither the Company nor the
            ---------------------------------------
Founder may make any assignment of this Agreement or any interest herein, by
operation of law or otherwise, without the prior written consent of the other
party; provided, however, that the Company may assign its rights under this
Agreement without the consent of the Founder in the event that the Company shall
hereafter effect a reorganization, consolidate with or merge into any other
corporation, partnership, organization or other entity, or transfer all or
substantially all of its properties or assets to any other corporation,
partnership, organization or other entity in which even for purposes of Section
1(h) hereof as used in determining the scope of the Company's business,
references to the Company shall be deemed to refer to the Company immediately
prior to such reorganization, consolidation or merger. This Agreement shall
inure to the benefit of and be binding upon the Company and the Founder, their
respective successors, executors, administrators, heirs and permitted assigns.

         7. Enforceability. If any portion or provision of this Agreement shall
            --------------
to any extent be declared illegal or unenforceable by a court of competent
jurisdiction, then the remainder of this Agreement, or the application of such
portion or provision in circumstances other than those as to which it is so
declared illegal or unenforceable, shall not be affected thereby, and each
portion and provision of this Agreement shall be valid and enforceable to the
fullest extent permitted by law.

         8. Waiver. No waiver of any provision hereof shall be effective unless
            ------
made in writing and signed by the waiving party. The failure of any party to
require the performance of any term or obligation of this Agreement, or the
waiver by any party of any breach of this Agreement, shall not prevent any
subsequent enforcement of such term or obligation or be deemed a waiver of any
subsequent breach.

         9. Notices. Any notices, requests, demands and other communications
            -------
provided for by this Agreement shall be sufficient if in writing and delivered
in person or sent by registered or certified mail, postage prepaid, return
receipt requested, to the Founder at the last address the Founder has filed in
writing with the Company or, in the case of the Company, at its main offices,
attention of the Chairman of the Board of Directors.

         10. Amendment.  This Agreement may be amended or modified only by a
             ---------
written instrument signed by the Founder and by a duly authorized representative
of the Company.

         11. Governing Law.  This is a Colorado contract and shall be construed
             -------------
under and be governed in all respects by the internal laws of the State of
Colorado, without giving effect to its conflicts of law principles.

                                       6

         12. Counterparts.  This Agreement may be executed in any number of
             ------------
counterparts, each of which when so executed and delivered shall be taken to be
an original; but such counterparts shall together constitute one and the same
document.

instrument by the Company, by its duly authorized officer, and by the Founder,
